Description

The invention relates to a substructure for plate-shaped covering elements of a floor covering, for example of balconies or terraces. The invention also relates to a floor structure with such a substructure. In addition, the invention relates to individual components of the substructure and/or the floor structure.

Substructures of the type discussed here serve as a substructure for floor coverings on terraces, balconies or other walkable areas. Such floor coverings often consist of plate-shaped covering elements, such as stone slabs. The substructure enables such covering elements to be laid in an orderly manner. An integral part of the substructures are substructure strips that support the covering elements. The substructure strips are usually arranged transversely and longitudinally and thus form a stable connection with one another.

A substructure for plate-shaped covering elements of a floor covering is made from DE 20 2015 008 251 U1 Another substructure is known from the DE 20 2016 002 718 U1 known.

One object of the invention is to propose a substructure of the type mentioned at the beginning, through which plate-shaped covering elements can be laid in an easy-to-assemble manner and the construction of a stable floor covering with a visually appealing surface is facilitated. Furthermore, a floor structure is to be proposed which is suitable for the use of such a substructure. In addition, individual components for such a substructure and/or such a floor structure are to be provided.

The problem is solved with a substructure having the features of claim 1. The problem is also solved with a substructure having the features of claim 5. The problem is also solved with a substructure having the features of claim 9. To solve the problem, a support element having the features of claim 14, a support element having the features of claim 18, a limiting element having the features of claim 21, a cover strip having the features of claim 23 and an end profile having the features of claim 25 are also proposed. To solve the problem, a floor structure having the features of claim 30 and a floor structure having the features of claim 34 are also proposed. Advantageous embodiments and/or configurations and/or aspects of the invention emerge from the subclaims, the following description and the figures.

A basic substructure for plate-shaped covering elements of a floor covering, for example of balconies, terraces or other preferably walkable surfaces, comprises at least one substructure strip and at least one support element for supporting at least one of the plate-shaped covering elements on the substructure strip. The support element comprises a preferably plate-shaped base body with an upper side and a lower side. The base body in turn comprises a support surface assigned to the upper side for supporting the at least one covering element thereon, a support surface assigned to the lower side and a side surface also assigned to the lower side, wherein the support element is placed on the substructure strip via the support surface and the side surface serves to limit lateral movement and/or to guide the movement of the support element relative to the substructure strip. For example, the side surface serves as a guide when the support element moves in the longitudinal direction of the substructure strip. The side surface is preferably fixed in position with respect to the base body. The support surface and/or the support surface are also preferably fixed in position with respect to the base body. For example, the side surface is formed on a projection that protrudes outwards from the base body, in particular a rib-shaped and/or web-shaped projection. The projection can be connected to the base body or to the underside of the base body, in particular be molded onto it.

The support element comprises at least one spring element which presses the base strip against the side surface of the support element. The support element promotes a stable support of the at least one covering element on the base strip. The support surface and the contact surface of the support element contribute to this, by means of which areas for contact with the at least one covering element and for contact with the base strip are already defined on the support element.

The support element also facilitates easy installation of the covering elements. The side surface and the spring element contribute to this. The side surface allows the support element to be positioned on the substructure strip at a desired location before at least one covering element is placed on it. The spring force of the spring element clamps the support element to the substructure strip at this desired location. This makes it is difficult to detach the support element from the base strip. Any changes in the position of the base strip can be made together with the pre-assembled support element to a certain extent without the support element immediately falling off the base strip or losing its position on the base strip.

If the side surface performs the function of guiding the movement of the support element relative to the base strip, it is possible to move the support element on the base strip along the side surface despite the clamping by means of the spring element, for example in order to align the support element relative to the base strip and/or relative to the at least one covering element to be supported.

Overall, the supporting element makes laying the panel-shaped covering elements easier. The supporting element also supports the construction of a stable floor covering with a visually appealing surface appearance, as the supporting element makes it easy to align the covering elements in an optimal way.

It is advisable for the support element to have at least one fastening point for fastening to the base strip. This allows the support element to be fastened to the base strip, for example after alignment with the base strip using the side surface. For example, the at least one fastening point is formed by a through opening, in particular a through hole, which is arranged, for example, in the area of the support element's contact surface. This allows the support element to be screwed to the base strip using a screw element.

The base body comprises a further side surface which is arranged at a distance from the side surface. Preferably, both side surfaces serve to limit lateral movement and/or to guide the movement of the support element relative to the base strip. It is provided that the further side surface is fixed in position with respect to the base body over two surface sections and is movable relative to the base body over at least one other surface section, wherein the movable surface section is assigned to the spring element in such a way that the spring element acts on the support element via the movable surface section and presses the support element against the side surface. The base strip is thus located between the side surface and the further side surface and is pressed against the other side surface by the restoring force of the spring element and the movable surface section of one side surface. The two side surfaces, together with the contact surface on the support element, form a receptacle for the base strip. The additional side surface provided in addition to one side surface supports the lateral movement limitation or the movement guidance of the support element relative to the base strip while maintaining the clamping force exerted by the spring element on the base strip.

It is provided that the further side surface is formed on a projection that protrudes outwards from the base body. It is also provided that the spring element is formed by the projection. This facilitates technically simple production. The further side surface and/or the spring element can be realized by a common material section of the support element. The projection is connected to the base body or to the underside of the base body in the area of the two fixed surface sections of the further side surface, in particular molded thereon, and in the area of the movable surface section of the further side surface without any connection to the base body, in particular to the underside of the base body. The movable surface section thus forms a spring section that can be moved elastically, which acts on the support element and presses the support element against the side surface.

In a technically simple manner, the projection in the area of its movable surface section is realized without connection to the underside of the base body in that the base body has a through opening there. The movable surface section bridges the through opening of the base body and is thus spring-elastically movable relative to the base body.

According to a further embodiment, it is provided that in the area of the movable surface section of the further side surface, the projection is rib-shaped and protrudes at least over a length section relative to the at least one fixed surface section in the direction of the side surface. This makes it easier for the movable surface section acting as a spring section to be tensioned by placing the support element on the base strip between the side surface and the further side surface, thereby building up a clamping force against the base strip. For example, the movable surface section runs in a wave-like manner in the direction of its longitudinal extension and in particular has an M-shape and/or W-shape.

In a further embodiment, the substructure comprises at least one transverse to the Cross bar arranged on the base bar. One possible embodiment of the support element is that the base body comprises a transverse surface assigned to the underside, which is transverse to the side surface. The support element is placed on the base bar and the cross bar via the mounting surface, the side surface serving to limit lateral movement and/or to guide the movement of the support element relative to the base bar and the transverse surface serving to limit lateral movement and/or to guide the movement of the cross bar. The transverse surface gives the support element the additional function of interacting with a cross bar, i.e. a cross bar that is transverse to the base bar. The support element can be the support element described above with the spring element. The support element can also be a different design that does not have such a spring element.

It can be provided that the transverse surface is formed on a material projection of the base body, wherein a lateral end of the material projection is spaced from the side surface in such a way that the base strip is accommodated between them and the lateral end serves as a lateral movement limiter and/or as a movement guide for the base strip. The material projection can be designed as a web or rib. For example, the material projection is elongated, wherein the transverse surface is formed on one of its long sides and the end face is opposite the side surface and serves as a lateral movement limiter and/or as a movement guide for the base strip. This promotes a simple geometric structure of the support element in order to work together with both a base strip and a transverse strip arranged transversely thereto. For example, the at least one material projection is arranged on a surface section of the underside of the base body that projects laterally beyond the base strip.

It can also be provided that a further transverse surface is assigned to the underside of the base body. For example, the further transverse surface is spaced apart from the transverse surface and the cross bar is accommodated between them, with the two transverse surfaces serving to limit lateral movement and/or to guide movement for the cross bar. This creates a sliding mount for the cross bar.

It is advisable for the support element to have at least one projection which protrudes outwards from the top of the base body and serves, for example, to form joints between two adjacent covering elements. The at least one projection can be designed as a web raised from the support surface of the base body. For example, the longitudinal extent of the web extends in such a way that the joint formed by the adjacent covering elements runs in the direction of the longitudinal extent of the web. For example, the at least one projection or web is formed on the base body.

Several such projections or webs can also be provided, each of which protrudes outwards from the top of the base body and serves, for example, to form joints between adjacent covering elements. The projections or webs can be arranged crosswise with their respective longitudinal extensions, so that the projections or webs can be used to form joints, which are present when there are a total of four covering elements supported on the support surface of the support element. The at least one web or projection can be detachably arranged on the base body in order to be able to form no, one or more joints using the at least one projection or web, depending on the number of covering elements to be supported on the support element. If the at least one projection or web is formed on the base body, a predetermined breaking point can be provided, which enables the projection or web to be broken off from the base body in a simple manner.

It is advisable for the support element to be a plastic part, for example manufactured by injection molding. This means that the support element can be manufactured cost-effectively as a mass-produced part. In principle, the support element can also be a metal part, for example made of or made from aluminum or an aluminum alloy.

Another basic substructure for plate-shaped covering elements of a floor covering, for example of balconies or terraces, comprises at least one substructure strip, a support structure for supporting at least one of the plate-shaped covering elements on the substructure strip and at least one limiting element for limiting the lateral overhang of one of the plate-shaped covering elements over the substructure strip. The support structure comprises at least one support element for supporting the at least one plate-shaped covering element on the substructure strip and optionally a support applied to the substructure strip or to the support element, which, for example, performs an anti-slip and/or impact sound-damping function between the components of the substructure placed on it.

The substructure strip can be the substructure strip described for the above substructure. The supporting element can also be the The supporting element described above can be the supporting element described above. In this respect, the further substructure can comprise the components and configurations already described for the above substructure as well as the associated advantageous effects.

The further substructure also includes the limiting element. The limiting element comprises a preferably plate-shaped base body with a top and a bottom. The base body of the limiting element comprises a contact surface assigned to the bottom and a side surface also assigned to the bottom, whereby the limiting element is placed on the base strip via the contact surface and the side surface serves to limit lateral movement and/or to guide the movement of the limiting element relative to the base strip. For example, the side surface serves as a guide when the limiting element moves in the longitudinal direction of the base strip.

The side surface is preferably fixed in position with respect to the base body. The contact surface is also preferably fixed in position with respect to the base body. For example, the side surface is formed on a projection that protrudes outwards from the base body, in particular a rib-shaped and/or web-shaped projection. The projection can be connected to the base body or to the underside of the base body, in particular be molded onto it.

Furthermore, the base body of the limiting element comprises a projection which rises from the top side and which is located at a distance from the support surface via a lateral extension section and serves as a stop for a front side of one covering element. Furthermore, it is provided that the limiting element has a maximum height starting from the bottom side in the area of its support surface, which is smaller than the height of the support structure in such a way that the limiting element can be moved between the one covering element and the substructure strip when the one covering element is supported on the support structure.

The limiting element provided in this substructure limits the lateral overhang of the at least one covering element over the substructure strip. This is helped by the projection that serves as a stop for the at least one covering element, by means of which the at least one covering element is supported in a predetermined position on the support structure and the substructure strip. This is a measure to achieve a uniform joint pattern in the floor covering to be installed and thus a visually appealing surface appearance. This is because the stop means that the covering element lying above can no longer slip sideways. The support structure provided also supports the installation of a stable floor covering with a visually appealing surface structure, since the supporting element of the support structure alone makes it easy to bring the covering elements into optimal alignment with one another, especially if the supporting element is the supporting element described for the above substructure.

The specified maximum height of the limiting element ensures that the limiting element itself has no load-bearing function for the covering elements resting on the substructure. This means that the limiting element can still be mounted on the substructure strip when the covering elements are already resting on the support structure. In the event that the limiting element is already placed on the substructure and the covering elements are also already resting on the substructure, it can still be aligned, i.e. moved into an intermediate or final position relative to the substructure strip and/or the associated at least one covering element. The height of the limiting element is preferably selected such that when the limiting element is placed on the substructure strip, the covering element above it has a certain amount of play in relation to the limiting element, at least when the covering element is not yet loaded, i.e. no object has been placed on it or no person is standing on it. This play is preferably so small that any possible tipping of the limiting element relative to the substructure strip is counteracted.

It can be provided that the base body of the limiting element has at least one, preferably several, spaced apart web-shaped elevations on the top. The elevations serve to support the covering element in order to prevent or at least counteract the tipping of the limiting element relative to the base strip. The web-shaped elevations limit the contact surface of the limiting element to the covering element to a minimum if the limiting element tends to tip relative to the base strip.

The elevations can run parallel or essentially parallel to the projection or side surface that serves as a stop. This results in manufacturing advantages, for example, since the limiting element can be made from an extruded profile. The elevations then run in the longitudinal direction of the extruded profile.

According to one embodiment, the base body of the limiting element in the area of the contact surface comprises a connection point spaced from the side surface, via which the limiting element can be fastened to the base strip by means of a fastening element. The connection point is, for example, a through hole or a through bore. The fastening element can be a screw element. The limiting element can thus be fastened to the base strip by the screw element reaching through the through hole and screwing the limiting element against the base strip. By fastening the limiting element against the base strip, the limiting element has a stabilizing effect on the covering element located above it in the area of its lateral overhang over the base strip. The covering element can therefore also be loaded in the protruding edge, for example by a person walking on it, without the covering element tipping sideways or at most a slight and tolerable lateral tipping occurring.

It is advisable for the limiting element to be a metal part, in particular made of or consisting of aluminum or an aluminum alloy. This gives the limiting element a high level of stability and deformation resistance. In this respect, any deformations on the limiting element when high loads occur are counteracted by the covering element above it. This helps to prevent the covering element above it from tipping over.

At least one cover strip can be provided for at least one of the substructures described above, which covers at least one of the outer sides of a floor surface formed by means of the substructure and the covering elements. The cover strip can be a decorative strip and serves to achieve a visually appealing surface appearance of the floor covering together with a visually appealing finish in the area of the edges of the floor covering.

According to one embodiment, the cover strip comprises two angle profiles, each with two legs, whereby one of the angle profiles has a plug-in receptacle on one of the legs, into which the other angle profile is inserted with one leg end. For example, the other leg of one angle profile has a contact surface for laying on the floor surface and the other leg of the other angle profile has a support surface for placing the cover strip on a subsurface. This also makes it easy for the cover strip to compensate for an inclined position of the subsurface relative to the laid floor surface. This compensation can be achieved by a variable insertion depth of one angle element in the insertion receptacle of the other angle element. This insertion depth is created automatically by one leg with the contact surface, which rests on the top of the floor covering.

For example, in a first step, the angle profile is placed with the contact surface on the subsurface and in a further step the other angle profile is pushed against the already mounted angle profile, forming a plug connection, until the leg with the contact surface comes into contact with the surface of the covering. This means that the side area of the floor covering is covered by the two-part cover strip, even if the subsurface is slanted or crooked relative to the surface of the floor covering.

It can be provided that the insertion receptacle is formed by a flat profile which is connected in the region of one longitudinal end to one leg of one angle profile, for example welded, riveted and/or glued, and forms an insertion opening with its other longitudinal end together with the one leg. This facilitates a technically simple manufacture of the insertion receptacle. For this purpose, it can also be provided that the flat profile is connected in the region of one longitudinal end to one leg of one angle profile by a clip connection in order to form the insertion receptacle.

The cover strip can be a metal part. For example, both angle profiles are made of metal. In principle, the cover strip can also be a plastic part.

In particular, the base strip comprises a top side and a bottom side and side surfaces between the top side and the bottom side, which form or at least partially form the outer circumference. The top side of the base strip corresponds at least partially with the contact surface of the support element, so that the support element can be placed with its contact surface on the top side of the base strip. At least one of the side surfaces of the base strip is designed to correspond to the side surface of the support element, so that when the support element is placed on the base strip, the side surface of the support element acts as a Stop and/or guide, for example along the longitudinal extension of the side surface of the support element. For example, the side surfaces of the base strip are arranged essentially orthogonally or orthogonally to the top of the base strip. For example, the top and at least part of the side surfaces of the base strip are part of a base body which is angular in cross-section, in particular square, and can be in the form of a hollow body. The side surfaces can be extended downwards towards the underside and form legs of a receptacle into which a damping element or another support element can be received, in particular can be received in a clamped manner.

The invention also includes individual components of the substructure or components which are suitable for use in at least one of the above substructures. In this respect, according to a further aspect of the invention, a support element is provided for the support of plate-shaped covering elements on a substructure strip. The support element can be the support element described for the above substructures. Reference is therefore made to the advantageous effects already described in this regard.

The support element comprises a preferably plate-shaped base body with an upper side and a lower side. The base body comprises a support surface assigned to the upper side for supporting at least one of the covering elements thereon, a mounting surface assigned to the lower side for mounting the support element on the base strip and a side surface also assigned to the lower side, wherein the side surface serves to limit lateral movement and/or to guide the movement of the support element relative to the base strip when the base strip is mounted on the mounting surface. Preferably, the side surface is fixed in position with respect to the base body. Preferably, the support surface and/or the mounting surface are also fixed in position with respect to the base body. For example, the side surface is formed on a projection protruding outwards from the base body, in particular a rib-shaped and/or web-shaped projection. The projection can be connected to the base body or to the lower side of the base body, in particular can be molded onto it.

The support element further comprises at least one spring element which is elastically movable transversely to the side surface such that when the support element is placed on the base strip, the support element is received against the force of the spring element between the spring element and the side surface and the spring element then presses the base strip against the side surface.

The base body comprises a further side surface which is arranged at a distance from the side surface. Preferably, both side surfaces serve to limit lateral movement and/or to guide the movement of the support element relative to the base strip when the base strip is accommodated between the side surfaces. The further side surface is fixed in position relative to the base body over two surface sections and is movable relative to the base body over at least one other surface section. The movable surface section is assigned to the spring element in such a way that when the support element is placed on the base strip, the spring element acts on the support element via the movable surface section and the support element presses against the side surface.

The further side surface is formed on a projection that protrudes outwards from the base body, and the spring element is formed by the projection. For this purpose, the projection is connected to the underside of the base body in the area of the two fixed surface sections of the further side surface, in particular molded thereon, and in the area of the movable surface section of the further side surface without connection to the underside of the base body, for example in that the base body has a through opening there. The movable surface section therefore has the function of a spring-elastically movable spring section and forms the spring element or is part of the spring element. For this purpose, it can be provided that in the area of the movable surface section of the further side surface the projection is rib-shaped or web-shaped and protrudes at least over a length section relative to the at least one fixed surface section in the direction of the side surface. The movable surface section can be wave-shaped, for example M-shaped or W-shaped. For example, the support element is a plastic part, in particular a plastic part manufactured by injection molding.

In addition or as an alternative, in addition to the side surface, which is designed to be used as a lateral movement limiter and/or as a movement guide for the base strip, a transverse surface is also assigned to the underside of the base body. The transverse surface runs transversely to the side surface and is designed to be used as a lateral movement limiter and/or as a movement guide for a transverse strip that is transverse to the base strip. For example, the side surface serves to limit the lateral movement and/or to guide the movement of the support element. opposite the base bar and the transverse surface for limiting lateral movement and/or for guiding the movement of the cross bar when the support surface is placed on the base bar and/or the cross bar.

The transverse surface is formed on a material projection of the base body, wherein a lateral end of the material projection is spaced from the side surface in order to accommodate the base strip therebetween and to be used as a lateral movement limiter and/or as a movement guide for the accommodated base strip. The material projection can be a web or a rib or a step or similar elevation, which is, for example, molded or formed onto the base body.

A further transverse surface can be assigned to the underside of the base body. For example, the further transverse surface is spaced from the transverse surface in such a way as to accommodate the transverse bar between them and to be used in particular as a lateral movement limiter and/or as a movement guide for the accommodated transverse bar.

It can also be provided that the further transverse surface is formed on a further material projection of the base body. For example, a lateral end of the further material projection is spaced apart from the side surface in such a way as to accommodate the base strip between them and to be used in particular as a lateral movement limiter and/or as a movement guide for the accommodated base strip. The further material projection can be a web or a rib or a step or similar elevation, which is for example formed or molded onto the base body.

Furthermore, it can be provided that the support element has at least one projection which protrudes outwards from the top of the base body and serves, for example, to form joints between two adjacent covering elements. The at least one projection can be designed as a web raised from the contact surface of the base body. For example, the longitudinal extent of the web extends in such a way that the joint formed by the adjacent covering elements runs in the direction of the longitudinal extent of the web. For example, the at least one projection or web is formed on the base body. Several such projections or webs can also be provided, each of which protrudes outwards from the top of the base body and serves, for example, to form joints between adjacent covering elements. The projections or webs can be arranged crosswise with their respective longitudinal extent, so that the projections or webs can be used to form joints which are present when a total of four covering elements are supported on the support surface of the support element.

It can also be provided that the support element has at least one fastening point for fastening to the base strip. For example, the at least one fastening point is formed by a through-opening, in particular a through-bore, which is arranged, for example, in the area of the support element's contact surface. The through-opening is designed in such a way that a fastening element, such as a screw element, can be inserted in order to fasten or screw the support element to the base strip.

According to a further aspect of the invention, a limiting element is provided for limiting the lateral overhang of a plate-shaped covering element over a substructure strip. The limiting element can be the limiting element described for the above substructure. Reference is therefore made to the advantageous effects already described in this regard.

The limiting element comprises a preferably plate-shaped base body with a top side and a bottom side. The base body of the limiting element comprises a contact surface assigned to the bottom side for placing the limiting element on the base strip and a side surface also assigned to the bottom side, wherein the side surface serves to limit lateral movement and/or to guide the movement of the limiting element relative to the base strip when the base strip is placed on the contact surface. For example, the side surface serves as a guide when the limiting element moves in the longitudinal direction of the base strip.

The side surface is preferably fixed in position with respect to the base body. The contact surface is also preferably fixed in position with respect to the base body. For example, the side surface is formed on a projection that protrudes outwards from the base body, in particular a rib-shaped and/or web-shaped projection. The projection can be connected to the base body or to the underside of the base body, in particular be molded onto it.

The base body of the limiting element further comprises a projection rising from the upper side, which has a lateral extension section at a distance from the There is a contact surface and it serves or can be used as a stop for a front side of the covering element. The base body also comprises at least one elevation on the top side, preferably several web-shaped elevations spaced apart from one another. The at least one elevation serves to support the covering element in order to prevent or at least counteract a tipping of the limiting element relative to the base strip.

It can be provided that the at least one elevation runs parallel or substantially parallel to the projection serving as a stop and/or the side surface. It can also be provided that the base body of the limiting element in the area of the contact surface comprises a connection point spaced from the side surface, such as a through hole, for fastening the limiting element to the base strip. It can also be provided that the limiting element is a metal part, in particular comprises or consists of aluminum or an aluminum alloy.

In a further aspect of the invention, a cover strip is provided for covering the outside of raised, particularly walkable floor areas of terraces or other floors. The cover strip can be the cover strip described for the above substructures. Reference is therefore made to the advantageous effects already described in this regard.

The cover strip comprises two angle profiles, each with two legs. One of the angle profiles has a plug-in receptacle on one of the legs, into which the other angle profile is inserted with one leg end. The other leg of one angle profile has a contact surface for laying on the raised floor surface and the other leg of the other angle profile has a support surface for placing the cover strip on a substrate. It can be provided that the plug-in receptacle is formed by a flat profile which is connected to one leg of one angle profile in the area of a long side end, for example welded, riveted and/or glued, and forms an insertion opening with its other long side end together with the one leg.

For example, the cover strip, in particular at least one of the angle profiles, is a metal part. Both angle profiles can also be a metal part. The metal part can consist of aluminum or an aluminum alloy or a stainless steel or a stainless steel alloy or can comprise such a material. The metal part can also consist of steel or can comprise such a material, with the metal part preferably then being provided with a corrosion-inhibiting or corrosion-preventing protective layer. In principle, the cover strip can also be a plastic part.

According to a further aspect of the invention, a finishing profile is provided for a surface of terraces or other floors, preferably formed by plate-shaped and/or plank-shaped covering elements. The finishing profile can be used as a finish for the surface or floor surface. The finishing element can also be used as a connection, for example to create a transition from the floor surface to a vertical facade surface.

The end profile comprises a plate-shaped, elongated base body with a top and a bottom. In particular, the base body is flat. A decorative and/or functional surface in one plane is assigned to the top of the base body. Furthermore, at least one longitudinal rib is assigned to the bottom of the base body, which extends with its longitudinal extension in the longitudinal direction of the base body. Seen in the cross-section of the end profile, the longitudinal rib protrudes downwards from the bottom of the base body and has a support surface at a lower end or in the region of a lower end for laying on a substructure or at least one of the substructures described above.

In one embodiment, a material section is arranged on the underside of the base body, which has a plug-in receptacle. Viewed in the cross-section of the end profile, the plug-in receptacle is arranged at a distance from the longitudinal rib and is designed to engage a limiting section of the substructure by means of a translatory engagement movement, in particular an exclusively translatory engagement movement, along an engagement direction, transverse to the plane of the decorative and/or functional surface. This facilitates easy installation of the end profile on the substructure, since the engagement of the limiting section in the plug-in receptacle enables exact positioning of the end profile on the substructure.

The end profile is designed to perform a drainage function. For this purpose, the base body of the end profile is provided with a large number of through holes, which are distributed over the decorative and/or functional surface. This facilitates the drainage of liquid on the floor surface. Any splashing of Rainwater, such as that which occurs during heavy rainfall, is counteracted, thereby providing protection for adjacent facade surfaces.

In particular, it is provided that a side wall of the insertion receptacle is formed on a further longitudinal rib which, viewed in the cross-section of the end profile, protrudes downwards from the underside and has a support surface at a lower end or in the area of a lower end for laying on the substructure. This also gives the material section a supporting function in relation to the substructure if, for example, the installation location on the substructure does not have a limiting section for insertion into the insertion receptacle.

In particular, it is further provided that the insertion receptacle has a bottom surface which is offset downwards at a predetermined distance from the underside of the base body in order to bring the decorative and/or functional surface of the end profile into a defined alignment with respect to the substructure by placing the bottom surface against the boundary section of the substructure.

For example, the longitudinal rib is molded onto the base body. For example, the material section is molded onto the base body. It is particularly provided that the end profile is made from a molded part produced by extrusion. In one embodiment, the end profile is designed as a metal part. For example, the end profile consists of aluminum or an aluminum alloy or stainless steel or a stainless steel alloy or comprises such a material. In principle, the end profile can also consist of steel or comprise steel. The end profile is then at least partially surrounded by a corrosion-protective coating.

Another aspect of the relates to a floor structure for terraces or other floors. The floor structure comprises one of the substructures described above or at least one of the designs of the substructures described above and covering elements laid on top of it. The covering elements can be plate-shaped. The covering elements can also be plank-shaped. For example, the substructure is placed on a substrate.

In one embodiment, the floor structure comprises the cover strip described above, wherein the contact surface of one angle profile of the cover strip rests on the floor surface formed by the covering elements and the contact surface of the other angle profile is placed on the subsurface.

In a further embodiment, the floor structure comprises the above-described end profile, wherein the support surface of the at least one longitudinal rib of the end profile rests on the above-described limiting element and/or the limiting element of the above-described substructure, in particular rests on the one elevation of the limiting element, and the limiting section protruding upwards from the base body of the limiting element engages in the insertion receptacle of the end profile and in particular is supported against the bottom surface of the insertion receptacle.

The invention enables a floor covering to be constructed from plate-shaped covering elements, such as ceramic stone slabs. The invention is also fundamentally suitable for constructing a floor covering from plank-shaped covering elements. The components described above, in particular the supporting element and/or the limiting element and/or the substructure strips and/or the cover strip and/or the end profile, can also be used for plank-shaped covering elements.

The invention facilitates the floor covering to have a flat and uniform installation pattern. The invention also facilitates the fact that the joints between adjacent covering elements are formed with precise dimensions over the entire floor surface and the covering elements lie exactly on a common plane. This avoids elevations at the joints and thus any tripping edges. In addition, the invention facilitates the fact that the edge area of the floor covering has a visually appealing and clean finish.

1 shows - in a schematic representation - a possible embodiment of a floor structure 200, for example a terrace, forming a floor surface 320, in a perspective view. The floor structure 200 comprises a substructure 100, which is placed on a flat surface 400, for example. The floor structure 200 further comprises a plurality of preferably plate-shaped covering elements 210, 220, 230, 240, 250, 260 laid on the substructure 100, which form a floor covering 300. The upper side of the floor covering 300 in turn forms the floor surface 320 of the floor structure 200. In order to illustrate the structure of the substructure 100, in the 1 the floor covering 300 has not yet been completely laid, thus revealing the substructure 100.

The substructure 100 comprises at least one substructure strip 90 and at least one support element 10, by means of which at least one of the covering elements 210 to 260 is or can be supported on the substructure strip 90. The substructure strip 90 can in turn be placed on the substrate 400, for example directly. At least one intermediate element can also be provided between the substructure strip 90 and the substrate 400. The intermediate element can be or comprise a pedestal support, in particular a height-adjustable pedestal support, or another support 110 or plate support. In addition or alternatively, the intermediate element can be or comprise, for example, a rubber-elastic base. The base can consist of a rubber-like material, such as rubber granulate, or comprise such a material, which is preferably vapor-permeable and/or impact sound-damping.

The substructure 100 preferably has the substructure strip 90 several times. For example, the substructure strips 90 are arranged at a distance from each other, in particular at a substantially equal distance from each other with respect to their respective long sides. For example, the distance between adjacent substructure strips 90.1 and 90.2 is dimensioned such that several covering elements 230, 240 in a row behind can be supported on each other, whereby the covering elements 230.1, 240.1 rest with their respective opposite edges on one of the adjacent substructure strips 90.1, 90.2.

Preferably, the adjacent substructure strips 90.1, 90.2 protrude with a surface section over the row of covering elements 230.1, 240.1, so that an adjoining row of covering elements 210.1, 220.1 can be supported on them, which runs, for example, parallel or essentially parallel to the other row of covering elements 230.1, 240.1. The support element 10 is provided for supporting the said covering elements 230.1, 240.1, 210.1 and 220.1 on the adjacent substructure strips 90.1, 90.2, which is preferably also present in multiple quantities.

In addition, further substructure strips 90.3 can be provided transversely to the substructure strips 90.1, 90.2, which are arranged at a distance from one another, which are connected to the substructure strips 90.3 that are spaced from one another, whereby the substructure strips 90 can together form a frame or cross connection. The further substructure strips 90.3 are preferably identical in construction to the substructure strips 90 already described above.

A further component of the substructure 100 can be at least one limiting element 50, which serves to limit the lateral overhang Ü of one of the covering elements 210 to 260 over the associated substructure strip 90. In the substructure 100, the limiting element 50 is preferably provided multiple times, so that at least one of the limiting elements 50 is assigned to the covering element laid in the edge area, such as the covering element 210, in order to limit the lateral overhang of the covering element 210 over the underlying substructure strip 90.

Another component of the substructure 100 can also be at least one cover strip 70, which serves to cover the outer sides of the floor surface 320 constructed by the floor structure 200. The cover strip 70 is also preferably provided multiple times, so that, for example, all outer sides of the floor structure 200 can be covered by means of the cover strip 70.

2 and 3 show a possible embodiment of the support element 10, as it is in the substructure 100 according to the 1 is used. The 2 the support element 10 in a perspective view from above and the 3 the support element 10 in a perspective view from below.

The support element 10 comprises a preferably plate-shaped base body 11 with an upper side 12 and a lower side 13. The base body 11 in turn comprises a support surface 14 assigned to the upper side 12 for supporting at least one covering element, for example at least one of the covering elements 210 to 260 of the substructure 100 according to the 1 . Furthermore, the base body 11 comprises a support surface 15 associated with the underside 13 for placing the support element 10 on a substructure strip, for example the substructure strip 90 of the substructure 100 according to the 1 . The base body 11 also comprises a side surface 16 which is also associated with the underside 13 and which serves to limit the lateral movement and/or to guide the movement of the support element 10 relative to the base strip 90 when the base strip 90 is placed on the support surface 15. The side surface 16 is designed to be fixed in position relative to the base body 11.

Preferably, the support element 10 further comprises at least one spring element 18 which is elastically movable transversely to the side surface 16 such that when the support element 10 is placed on the base strip 90, the support element 10 is received against the force of the spring element 18 between the spring element 18 and the side surface 16 and the spring element 18 presses the base strip 90 against the side surface 16 ( 4 ). The side surface 16 allows the support element 10 to be positioned on the base strip 90 at a desired location, for example by moving along the side surface 16 before the at least one covering element 210 is placed thereon. The spring force of the spring element 18 then holds the support element 10 in a clamped manner at this desired location on the base strip 90.

In addition, the base body 11 comprises a further side surface 17, which is at a distance A ( 3 ) to the side surface 16. Preferably, both side surfaces 16, 17 then serve to limit the lateral movement and/or to guide the movement of the support element 10 relative to the base strip 90, for example by accommodating the base strip 90 between the side surfaces 16, 17. It is provided that the further side surface 17 is fixed in position with respect to the base body 11 via two surface sections 20, 21 and is movable relative to the base body 11 via at least one other surface section 22, which is arranged between the two fixed surface sections 20, 21. The movable surface section 22 is assigned to the spring element 18, so that when the support element is placed 10 on the base strip 90, the spring element 18 acts on the support element 90 via the movable surface section 22 and presses the support element 90 against the side surface 16 ( 4 ).

The further side surface 17 is formed on a projection 23 that projects outward from the base body 11. The spring element 18 is formed by the projection 23. This is realized in such a way that the projection 23 is formed on the underside 13 of the base body 11 in the area of the fixed surface sections 20, 21 and is not connected to the underside 13 of the base body 11 in the area of the movable surface section 22, for example in that the base body 11 has a through opening 24 there. The projection 23 can then carry out a spring-elastic movement in the area of the movable surface section 22, so that the projection 23 forms a spring-elastic movable spring section 19 in the area of the movable surface section 22, which is an integral part of the spring element 18 or forms the spring element 18. For example, the projection 23 is rib-shaped and/or web-shaped at least in the area of the movable surface section 22, i.e. in the area of the elastically movable spring section 19, and protrudes in relation to the fixed surface sections 20, 21 in the direction of the side surface 16. For example, the spring section 19 is formed by a wave-shaped, in particular M-shaped or B-shaped length section of the projection 23. Preferably, the projection 23 is also rib-shaped or web-shaped in the area of the fixed surface sections 20, 21.

The side surface 16 is preferably formed on a projection 25 that protrudes outward from the base body 11. The projection 25 can be rib-shaped and/or web-shaped and its longitudinal extension can run, for example, at the same distance or essentially the same distance from the projection 23, for example in the region of at least one of the fixed surface sections 20, 21. The projection 25 is preferably formed on the underside 13 of the base body 11.

Preferably, the side surface 16 is arranged transversely to the support surface 15. For example, the side surface 16 runs essentially orthogonally or orthogonally to the support surface 15. Preferably, the further side surface 17 is arranged transversely to the support surface 15. For example, the further side surface 17 runs essentially orthogonally or orthogonally to the support surface 15. For example, the side surface 16 and the further side surface 17 as well as the support surface 15 form an essentially U-shaped or U-shaped receptacle for the base strip 90.

The base strip 90 comprises an upper side 92 and a lower side 93 and side surfaces 94, 95 between the upper side 92 and the lower side 93, which form or at least partially form the outer circumference ( 4 and 6 ). The top side 92 of the base strip 90 corresponds at least partially to the support surface 15 of the support element 10, so that the support element 10 can be placed with its support surface 15 on the top side 92 of the base strip. At least one of the side surfaces 94, 95 of the base strip 90 is designed to correspond to the side surface 16 of the support element 10, so that when the support element 10 is placed on the base strip 90, the side surface 16 serves as a stop and/or guide relative to the then facing side surface 94 or 95 of the base strip 90, for example along the longitudinal extent of the side surface 16.

For example, the side surfaces 94 and 95 of the base strip 90 are arranged essentially orthogonally or orthogonally to the top side 92. For example, the top side 92 and at least a part of the side surfaces 94 and 95 are a component of a base body of the base strip 90, which is angular in cross-section, in particular square, and can be in the form of a hollow body. The side surfaces 94, 95 can be extended downwards to the bottom side 93 and form legs of a receptacle in which a base part, such as a damping element 91, can be accommodated ( 4 and 6 ).

The support element 10 can additionally be provided with at least one fastening point 26 for fastening to the base strip 90. The fastening point 26 can be a through-opening. The fastening point 26 is preferably located in the area of the mounting surface 15, so that when the support element 10 is placed on the base strip 90, a fastening element, such as a screw element, can be inserted via the fastening point 26 in order to fasten the support element 10 to the base strip 90 using the fastening point 26.

Preferably, the support element 10 also comprises at least one projection 28 which protrudes outward from the upper side 12 of the base body 11 and allows the formation of joints between two adjacent covering elements, such as the covering elements 210 and 240 of the substructure 100 according to the 1 The projection 25 can be designed as a web raised from the support surface 14 of the base body 11. For example, the longitudinal extent of the web extends such that the joint formed by the adjacent covering elements 210, 240 runs in the direction of the longitudinal extent of the web.

Preferably, the projection 28 is molded onto the base body 11. In the region of the molding, the base body 11 can have a recess 27. Furthermore, a predetermined breaking point can be provided on the projection 28, at which the projection 28 can be specifically separated from the base body 11. Preferably, the projection 28 can be provided multiple times, for example four times. The projections 28 can be aligned with each other in a cross arrangement, wherein the respective opposite projections 28 can be at a distance from each other. As a result, up to four of the covering elements 210 to 260 can be supported on the support element 10, each with a corner region.

4 shows the supporting element 10 in the mounted state on the substructure strip 90, as for example in the substructure 100 according to the 1 The base strip 90 is placed there, for example, on at least one damping element 91, which can form the support 110, as is the case with the 1 The damping element 91 serves, for example, to dampen impact sound and/or to promote vapor diffusion. The damping element 91 can consist of rubber or rubber granulate or can comprise such a material. For example, the damping element 91 is accommodated in a receptacle provided on the underside 93 of the base strip 90 between the side surfaces 94 and 95 or legs of the receptacle ( 6 ).

When the support element 10 is placed on the base strip 90, the side surface 16 is in contact with the side surface 94 of the base strip 90, with the spring element 18 on the other side pressing against the side surface 95 of the base strip 90. In this state, the fixed surface sections 20, 21 of the further side surface 17 serve as additional movement guides and/or side limitations.

As from the 4 As can be seen, the support element 10 can have a support 29 on its support surface 14. The support 29 can perform a vapor diffusion function and/or a sound-damping function and can consist of rubber or rubber granulate or contain such a material. In this case, the support element 10 together with the support 29 forms a support structure for at least one of the covering elements, such as the covering elements 210 to 260 of the substructure 100 according to the 1 .

5 shows a possible embodiment of the limiting element 50, as it is used for example in the substructure 100 according to the 1 is used. The limiting element 50 comprises a preferably plate-shaped base body 51 with an upper side 52 and a lower side 53. The base body 51 in turn comprises a support surface 55 assigned to the lower side 53 for placing the limiting element 50 on a substructure strip, such as the substructure strip 90 of the substructure 100 according to the 1 . Furthermore, the base body 51 comprises a side surface 56 which is also assigned to the underside 53 and which serves to limit the lateral movement and/or to guide the movement of the limiting element 50 relative to the base strip 90 when the base strip 90 is placed on the support surface 55.

Furthermore, the base body 51 comprises a projection 58 which rises from the upper side 52 and which is provided via a lateral extension section 59 at a distance from the support surface 55 and serves as a stop for a front side of a covering element, for example the covering element 210 of the substructure 100 according to the 1 The projection 58 can be formed on a material section which extends beyond the underside 53 of the limiting element 50, so that a further projection 64 extending outward from the underside 53 is formed.

The base body 51 of the limiting element 50 can have at least one, preferably several, spaced apart web-shaped elevations 60, 61, 62 on the upper side 52. For example, the elevations 60, 61, 62 serve to support the covering element 210 located above them ( 1 ) to counteract the tilting of the limiting element 50 relative to the substructure strip 90. This makes it easier to erect the substructure 100.

Preferably, the base body 51 of the limiting element 50 has, in the region of the support surface 55, a connection point 57 spaced from the side surface 56, via which the limiting element 50 can be fastened to the base strip 90 by means of a fastening element 54. 6 shows the limiting element 50 mounted on the base strip 90, wherein the limiting element 50 is fastened to the base strip 90 by means of the connection point 57 and the fastening element 54. For example, the connection point 57 is formed by a through hole and the fastening element 54 is a screw element, so that the limiting element 50 is fastened by inserting the screw element 54 through the through hole and screwing it into the base strip 90. By fastening the limiting element 50 against the base strip 90, a tilting of the covering element 210 located above it is counteracted, if the covering element 210 is loaded, for example by walking on the edge area protruding beyond the substructure strip 90.

The side surface 56 is formed, for example, on a projection 63 that projects outward from the base body 51. The projection 63 can be rib-shaped and/or web-shaped. The projection 63 is preferably formed on the base body 51. For example, the side surface 56 is arranged transversely to the support surface 55, for example the side surface 56 is essentially orthogonal or orthogonal to the support surface 55. The side surface 56 preferably uses that section, in particular that side surface 94 or 95 of the base strip 90, which can also be used for applying and/or for guiding the movement of the support element 10 with its side surface 16. Preferably, the support surface 55 is designed in such a way that the limiting element 50 can be placed on the upper side 92 of the base strip 90, namely on the same area on which the support element 10 with its support surface 15 can be placed.

7 and 8 show the limiting element 50 in the installed state on the substructure strip 90, wherein in each case a covering element, in particular the covering element 210 of the substructure 100 according to the 1 , is located above the limiting element 50. The covering element 210 is supported on the left and right sides by a respective support structure on the substructure strip 90, wherein the support structure comprises, for example, the support element 10 and the support 29. The limiting element 50 is located between the support structures. 7 shows a front view of this structure and the 8 shows a rear view of it.

As from the 7 As can be seen, the projection 58 of the limiting element 50 serves as a stop for an overhang of the covering element 210 that protrudes beyond the base strip 90. The stop or projection 58 is brought into contact with the front side of the covering element 210 or at least there is a gap between them. From the 8 It can be seen that the covering element 210 is supported on the support 29 and the supporting element 10 on the substructure strip 90.

The limiting element 50 is preferably arranged with play S between the underside of the covering element 210 and the upper side 92 of the base strip 90, so that the limiting element 50 can be moved back and forth relative to the base strip 90 when the covering element 210 is in place. This is achieved by the fact that the limiting element 50, starting from the underside 53, has a maximum height or construction height in the area of its mounting surface 55, which is smaller than the height or construction height of the support structure, i.e. the height of the support element 10 and the height or thickness of the support 29. The maximum height of the limiting element 50 is selected such that, on the one hand, the limiting element 50 is still movable between the covering element 10 and the base strip 90 when the covering element 210 is supported on it. On the other hand, the clearance is preferably dimensioned such that tilting of the limiting element 50 relative to the base strip 90 is counteracted.

9 shows a possible embodiment of the cover strip 70, which for example in the substructure 100 according to the 1 is used. The cover strip 70 serves to cover at least one of the outer sides of the floor surface 320 formed by the substructure 100 and the covering elements 210 to 260. The cover strip 70 comprises two angle profiles 71, 72, each with two legs 71.1, 71.2, 72.1, 72.2, wherein one of the angle profiles 71, 72 has an insertion receptacle 73 on one of the legs 71.1, 71.2, into which the other angle profile 72 is or can be inserted with a leg end 74.

The other leg 71.1 of one angle profile 71 comprises a contact surface 76 for resting on the floor surface 320. The other leg 72.1 of the other angle profile 72 comprises a support surface 75 for placing the cover strip 70 on the substrate 400. For example, the insertion receptacle 73 is formed by a flat profile 77 which is connected to one leg 71.2 of one angle profile 71 in the region of a longitudinal end 78 and forms an insertion opening 80 with its other longitudinal end 79 together with the one leg 71.2.

10 shows the cover strip 70 in the assembled state, as shown in the example of the substructure 100 according to the 1 The plug connection of the angle profiles 71, 72 makes it possible to compensate for an inclined position of the substrate 400 relative to the laid floor surface 320 by varying the insertion depth of one angle element 72 in the insertion receptacle 73 of the other angle element 71. In this way, an interruption of the cladding is avoided.

In order to permanently maintain the angle profiles 71 and 72, once aligned with one another via the plug-in connection, in the aligned position relative to one another in the cover strip 70, at least one fixing element 82 can be provided, by means of which the angle profiles 71 and 72 are fixed in a fixed position relative to one another. The fixing element element 82 is, for example, a pin element which is passed through the plug connection so that the inserted leg 72.2 is prevented from being pulled out of the plug-in receptacle 73.

The angle profile 72 can have at least one, preferably two, projections 81 protruding outwards on its other leg 72.1 on the top side. The projections 81 can serve as a receptacle or lateral limitation for a damping element, in particular the damping element 91, which can be used as a base for the base strip 90 (cf. 4 ).

The 11 the supporting element 10.1 in a perspective view from above and the 12 the support element 10.1 in a perspective view from below. Components of the support element 10.1 of the 11 and 12 , which are connected to components of the supporting element 10 of the 2 and 3 are identical or functionally equivalent, are provided with the same reference numerals; in this respect, reference is made to the description of the support element 10 of the 2 and 3 referred to.

The supporting element 10.1 of the 11 and 12 differs from the support element 10 of the 2 and 3 in that the underside 13 of the base body 11 is assigned a transverse surface 30 which runs transversely to the side surface 16, in particular at a right angle to the side surface 16. The transverse surface 30 is designed such that it can be used as a lateral movement limiter and/or as a movement guide of a transverse strip which is transverse to a substructure strip, wherein the substructure strip is supported against the side surface 16.

The transverse surface 30 is formed on a material projection 32 of the base body 11 and a lateral end 34 of the material projection 32 is spaced from the side surface 16 such that the base strip can be received therebetween and the end 34 can be used as a lateral movement limiter and/or as a movement guide for the received base strip.

Preferably, a further transverse surface 31 is assigned to the underside 13 of the base body 11. Preferably, the further transverse surface 31 is spaced from the transverse surface 30 in such a way that the transverse bar can be accommodated therebetween and both transverse surfaces serve as a lateral movement limiter and/or as a movement guide for the accommodated transverse bar.

For example, the further transverse surface 31 is formed on a further material projection 33 of the base body 11. For example, a lateral end 35 of the further material projection 33 is spaced from the side surface 16 in such a way that the base strip can be accommodated between the lateral end 35 and the side surface 16 and the lateral end 35 of the further material projection 33 together with the lateral end 34 of the material projection 32 serve as a lateral movement limiter and/or as a movement guide for the accommodated base strip.

14 , 15 and 16 show the support element 10.1 together with a substructure strip 90' and a transverse strip 90''. In the 14 the support element 10.1 is placed with its support surface 15 on the upper side of the base strip 90' and/or the cross strip 90'', whereby the base strip 90' is received between the side surface 16 and the lateral ends 34 and 35 of the material projections 32, 33. The cross strip 90'' is located between the cross surfaces 30, 31. The 15 shows the substructure strip 90' and the cross strip 90'' as well as the supporting element 10.1 before assembly. 16 clarifies the arrangement when at least the base strip 90' is in support on the support surface 15.

17 shows a further possible embodiment of a floor structure 200' in a sectional view in the area of a side closure. The floor structure 200' comprises a further embodiment of a cover strip 70'. The floor structure 200' has a substructure strip in the manner of the substructure strip 90, which is supported or rests with its underside on a damping element 91'. On the top of the substructure strip 90 there is a covering element 270. A limiting element in the manner of the limiting element 50 is provided for lateral limitation.

The cover strip 70' is constructed, for example, in the manner of the cover strip 70. The cover strip 70' differs from the cover strip 70 in that in the cover strip 70' the insertion receptacle is formed by the flat profile 77 being connected to the leg 71.2 by a clip connection 84. For this purpose, the leg 71.2 has a clip element 84.1 and the flat profile 77 has a corresponding clip receptacle 84.2.

In the cover strip 70', the leg 72.1 of the angle profile 72 has a receptacle 85 in order to introduce the damping element 91' therein and thus to hold it in a defined position, for example for lateral closure, by the cover strip 70'. The receptacle 85 can be designed in the manner of a dovetail receptacle, so that a positive connection with the damping element 91' is created with inwardly projecting edges when it is pressed into the receptacle. The leg 72.2 also has an outwardly projecting projection or web 83 on its end facing the other leg 72.2.

18 shows another possible embodiment of a floor structure 200'', in which a so-called terrace bearing 150 is provided. The terrace bearing 150 is supported with its base against the web 83 and stands with its base on the leg 72.1 of the angle profile 72 of the cover strip 70. This prevents the cover strip 70' from moving in the direction of the terrace bearing 150 due to external forces. At the same time, a distance is provided between the web 83 and the leg 72.2, in which, depending on requirements, the longitudinal end 79 of the flat profile 77 can be accommodated.

19 shows the example of the floor structure 200'', as it is used for example in the 18 As already shown, a possible installation situation with regard to the area of a transition to a facade wall 500 without the 18 The floor structure 200' uses a substructure 100'', which, for example, corresponds to the substructure 100 according to the 7 corresponds, whereby in the 19 the terrace support 150 is used. In the floor structure 200'', a last covering element 280 is shown as an example for the entire floor area created by covering elements. The last covering element 280 faces the facade wall 500 and in a transition a finishing profile 40 is placed on the substructure 100''. 20 shows the end profile 40 in a perspective view.

The end profile 40 has a plate-shaped, elongated base body 41. The base body 41 has an upper side 42 and a lower side 43 opposite the upper side 42. The end profile 40 further comprises two mutually opposite longitudinal end faces 44.1, 44.2 and two mutually opposite transverse end faces 44.3, 44.4. For example, one of the longitudinal end faces 44.1, 44.2 faces the facade wall 500 and the other longitudinal end face 44.1 faces the last covering element 280. Preferably, the longitudinal end faces 44.1, 44.2 and/or the transverse end faces 44.3, 44.4 form the front outer sides of the base body 41.

In the end profile 40, a decorative and/or functional surface 45 is assigned to the top 42. The decorative and/or functional surface 45 is preferably formed on the top 42 of the base body 41. Furthermore, a longitudinal rib 46 is provided on the underside 43 of the base body 41. The longitudinal rib 46 extends with its longitudinal extent in the longitudinal direction of the base body 41. Seen in the cross section of the end profile 40, the longitudinal rib 46 projects downwards from the underside 43 and a lower end 46.1 has a support point, in particular a support surface 46.2 for laying on the substructure 100''. For this purpose, the support surface 46.2 is formed on an angled edge section of the longitudinal rib 46.

The end profile 40 further comprises a material section 47 on the underside 43, which comprises a plug-in receptacle 47.1. Seen in the cross section of the end profile 40, the plug-in receptacle 47.1 is arranged at a distance from the longitudinal rib 46 and is designed to engage a limiting section, namely the projection 58 of the limiting element 50, by means of a translatory engagement movement along an engagement direction 47.2 ( 20 ) transversely to a plane formed by the decorative and/or functional surface 45.

The longitudinal rib 46 and the insertion receptacle 47.1 enable the installation of the end profile 40 on the substructure 100'' in such a way that the support surface 46.2 of the longitudinal rib 46 rests on the limiting element 50, in particular on the elevation 61 of the limiting element 50, and the upwardly projecting projection 58 of the limiting element 50 engages in the insertion receptacle 47.1 of the end profile 40 and is supported against a base surface 47.5 of the insertion receptacle 47.1 ( 19 ). As a result, the base body 41 is arranged at a distance from the lower limiting element 50 and any lower substructure strips, such as the substructure strip 90. This in turn forms at least one free space below the base body 41, which extends in the longitudinal direction of the end profile 40 when the end profile 40 is in the installed state.

The end profile 40 is designed to perform a drainage function. The drainage function is achieved in that the base body 41 has a plurality of distributed through openings 48, each of which has a passage from the top side 42 through the bottom side 43. Any precipitation or other liquid that hits the top surface 42 can thus run off via the through-openings 48 and be drained off laterally through the free space below the base body 41, so that a splashing effect caused by raindrops hitting the decorative and/or functional surface 45 is counteracted. In this respect, the end profile 40 promotes drainage of liquid that has backed up or accumulated on the covering surface.

Preferably, the base surface 47.5 is arranged offset downwards from the underside 43 of the base body 41 at a predetermined distance. The predetermined distance is selected such that by placing the limiting section 58 on the base surface 47.5, the decorative and/or functional surface 45 of the end profile 40 is brought into a defined alignment with respect to the substructure 100''. For example, the decorative and/or functional surface 45 is in a horizontal position in the defined alignment and/or is located at an approximately parallel distance to the top of the at least one substructure strip 90 or the decorative and/or functional surface 45 is flush with the covering surface formed by the covering elements.

In addition to the base surface 47.5, the material section 47 has opposite side surfaces, with the side surfaces and the base surface 47.5 forming the insertion receptacle 47.1. The side surfaces are preferably each formed on a leg 47.3, 47.4. The legs 47.3, 47.4 can each be formed as a longitudinal rib, the length of which extends in the longitudinal direction of the base body 41. Viewed in the cross section of the end profile 40, the legs 47.3, 47.4 preferably each protrude downwards from the underside 43 of the base body 41. Viewed in the cross section of the end profile 40, the length of one of the legs 47.3, 47.4 can be longer than the other leg 47.4. Preferably, the longer leg 47.3 has a support surface 47.6 at a lower end for laying on the substructure 100''.

The end profile 40 preferably has an outer rib 49 or 49' on each of its longitudinal end faces 44.1, 44.2, which form, for example, a frontal boundary of the end profile 40. The ribs 49, 49' are preferably arranged on the underside 43 of the base body 41 and protrude downwards from it. Preferably, at least one of the ribs 49 or both ribs 49, 49' have a shape which, as seen in the cross section of the end profile 40, is formed by several legs. The ribs 49, 49' are preferably identical to one another, and are arranged as mirror images of one another.

Preferably, the at least one rib 49 or 49' has a first leg 49.1, which is arranged on the underside 43 of the base body 41. Preferably, this is followed by a second leg 49.2, which is transverse to the first leg 49.1. The second leg 49.2 and a section of the base body 41 located above it form a groove or similar recess, which extends, for example, in the longitudinal direction of the base body 41 and can be used, for example, to accommodate fastening elements, by means of which the end profile 40 can be fastened to the base strip 90.

Preferably, it is also provided that the section of the base body 41 used to form the groove has an angled edge 49.5 on its longitudinal end 44.1 or 44.2, which is angled downwards, for example. Preferably, a third leg 49.3 is arranged on the second leg 49.2, which is transverse to the second leg 49.2 and has a support surface 49.4 at its end for resting against the substructure 100''.

Preferably, the material section 47 and/or the longitudinal rib 46 and/or the outer ribs 49, 49' are formed on the base body 41. For example, the end profile 40 is formed by an extruded molded part and consists of aluminum or comprises such a material.

In this description, the term "plate-shaped covering element" is to be understood in particular as referring to cuboid-shaped or rectangular covering elements, which are made of natural stone, concrete, ceramic or similar stoneware, for example. In this description, the term "plank-shaped covering element" is to be understood in particular as referring to the covering element being much longer than it is wide. Such covering elements are made of wood or a composite material, such as WPC, for example.
