Description

Laying system for a floor built from panels and supporting frame therefor

Technical Field

The present invention relates to floor covering systems and is particularly suitable for use with ceramic tiles, natural stone tiles and wood panels.

Background

In the case of tiles or stone tiles, the floor is in principle laid on a correspondingly prepared foundation, for example a plastered layer, with the aid of a suitable adhesive, the joint width here being determined mostly by the insertion of joint cross-bars and these joints having to be subsequently sewn. This laying is rather laborious in terms of the tools required and the materials required and also requires a considerable manual skill of the worker. In addition, a long time is required before the pavement can be stepped on. A further disadvantage is that the floor covering laid as intended cannot be detached without problems, i.e. without damaging the floor.

In wood boards, such as parquet floors or laminates for floor covering, it is known to provide grooves on two intersecting side faces and tenons on the other two intersecting side faces. When laying the boards, the boards are butted and bonded to each other with corresponding grooves and tenons, respectively. The board decking cannot be subsequently disassembled here without destroying the board.

DE19962812a1 or DE20009717U1 disclose stone tiles with a supporting frame and a seal. DE19962812a1 discloses that the edges of the floor and wall panels to be laid each have a profiled edge, which can be glued to the panels. The profiled frame is formed in such a way that a first leg for the support plate and a second leg for the support on the circumferential edge surface of the plate are present. Furthermore, the leg extending at the edge of the panel has a projection on the side facing away from the panel, which projection together with the projection of the adjacent panel ensures that a minimum seam width is achieved. A covering section bar is added into a joint formed by two special-shaped frame edges which are arranged in a mirror symmetry mode. The cladding profile does not slip out through a tooth. A slip-resistant damping layer can be provided on the plate, but here the edge region of the bottom side of the plate is free, since there the profiled frame is arranged around. The plate, pre-formed with profiled rims, is laid on the ground in such a way that the projections butt together.

DE20009717U1 discloses that between two adjacent plates a substantially T-shaped support profile is provided, which has two lateral support webs for supporting a plate and a central positioning section with a slot for sealing. The locating portion extends for a distance along the edge of the plate and the seal is formed such that it provides a plurality of successive sealing surfaces towards the upper surface of the plate. A sealing strip is arranged between the plate and the lateral support webs, which sealing strip prevents water which may flow past the sealing strip from flowing out onto the bottom surface of the plate. In addition, a guide web can be provided in the region of the receiving web in order to form the drainage channel.

Disclosure of Invention

The object of the invention is to provide a laying system in which the laying of the boards can be carried out relatively simply, that is to say by less skilled persons. The laying system is particularly suitable for natural stone slabs such as granite slabs, marble slabs and the like, but also for slabs made of wood, ceramic materials or other materials. Furthermore, it should be ensured that the decking can be disassembled again as required without damaging the individual panels.

With the laying system proposed according to the invention, the above-mentioned disadvantages can be avoided. Each plate rests with its bottom surface at least partially on the surface on a support frame having a profiled rim with a resting area, wherein the support frame has a cross piece projecting towards the upper surface of the plate beyond the resting surface, which cross piece extends at least partially along the edge of the plate towards the upper surface of the plate. The support frames can be connected to each other. The cross-webs are arranged only on two adjacent profiled rims, while the other two profiled rims have a receiving region without cross-webs. The first profiled rim has at least one locking extension projecting beyond the plate, and the other two second profiled rims have at least one locking extension located below the plate, each profiled rim having a profiled rim cooperating with the other profiled rim.

If the panels are square or rectangular, the supporting frame has four profiled frame sides, wherein the laid rows of parallel panels can be moved by means of a special connecting structure. In this way, the plates can be arranged offset. Thus, in this case, instead of four corners being paired together at one corner of one board, two corners are against one side edge of an adjacent board row. By the separate laying of the mutually sealing joint rubbers, a precise and constant seam pattern is obtained, which is also believed to have a waterproof sealing property.

According to the invention, expansion joints are no longer required when laying large areas, since no hard contact with the foundation occurs by floating the planks. Thus, the risk of cracks in the floor covering or in the individual boards, such as occurs when the boards are stuck to a cement seamless floor, is not present. Furthermore, no glue is used for the purpose of sheeting. A significant advantage is obtained when laying high-priced boards, such as granite boards or the like, because here the additional cost of the laying system becomes less important from the point of view of the price of a single piece, while a much more important advantage is that even for a barely trained panellist, paving errors are avoided. In addition, the cost of the floor is obviously reduced.

By means of the floating floor, the granite floor can be quickly and cheaply laid on the existing wood structure without a pre-construction site in the dismantling and construction process of the old building paved with the wood floor. In the case of wooden buildings, granite and natural stone can also be laid by means of the invention.

When using the laying system according to the invention, the usual problem of imperfect stepping sound insulation in existing cement-based seamless floors (often due to the occurrence of acoustic bridges as a result of an irregular laying) is no longer present in connection with a stepping sound insulation material and an optimum sound insulation effect is ensured. For this purpose, the support frame has a tread sound insulating material on its underside. In this case, it is preferable that a step sound insulating material is provided under the mounting region.

In the laying system according to the invention, a sealing profile is formed on the crosspiece, which sealing profile extends along the panel edge towards the upper surface of the panel. Furthermore, the support frame and the plate always form a unit and are bonded to one another.

In addition to the laying system, the subject of the present application is also a support frame with profiled rims with a receiving area, the support frame having a cross piece projecting towards the upper surface of the plate to be placed in the receiving area beyond the receiving area, the cross piece itself extending at least sectionally along the plate edge towards the upper surface of the plate, the support frame being able to be joined to each other, characterized in that the cross piece is provided only on two adjacent profiled rims, the other two profiled rims having a receiving area without a cross piece, at least one of the profiled rims having at least one locking extension projecting beyond the plate, the other two profiled rims having at least one locking extension located below the plate, one of said profiled rims cooperating with the other of said profiled rims, respectively.

In the support frame according to the invention, the support frame and the plate constitute a brick. Here, a floor is constructed from the above-described tiles. Furthermore, a seal is fixed to the crosspiece. In this case, a groove is formed in the crosspiece in which the seal can be seated. In addition, the support frame has a sound-insulating profile on its underside, which is accommodated in a groove. According to the invention, the support frame has reinforcing ribs and the support surface has recesses, the reinforcing ribs having a groove on the underside thereof for receiving the sealing and sound-insulating profile. In this case, the recesses taper conically in the receiving surface, starting from the plate.

According to the invention, the support frame is prefabricated from a single piece. Alternatively, the support frame is formed by assembled profiles. Furthermore, both the sealing and the sound-insulating profile are materially connected to the frame, in particular by spraying. In addition, the locking extension is in the shape of a protrusion.

Detailed Description

The embodiments shown are based on a floor covering consisting of a number of aligned slabs, such as granite slabs, which are laid floating on a foundation, for example a rough concrete floor or wood flooring, with a gap joint between them.

Fig. 1 shows in one view a quadrilateral frame 1 for supporting a plate (not shown in this figure), such as a granite plate. The frame 1 is made of plastic and is prefabricated, and it can be made of an integral injection-molded part or of parts consisting of an extruded profile. Recycled plastics can also be used as raw materials.

Of the four rims 1a-1d of the frame 1, two rims 1c, 1d adjacent to each other have a profiled insert part 3 as shown in the cross-sectional view of fig. 4. The other two rims 1a, 1b have a profiled insert part 4 as shown in the cross-sectional view of fig. 5. The four frame sides 1a-1d have a strip-shaped support surface 5 on which a plate 2 insertable into the frame rests in the laid state.

Fig. 2a shows such a plate 2 resting on a strip-shaped support surface 5 with profiled inserts 4. When the width of the plate is 305 mm, the width of the bearing surface 5 is suitably equal to 20 mm.

The distance of the laying foundation (cement-based flat ground) from the installed plate 2, which is defined by the thickness (structural height) of the bearing surface 5 of the frame 1, can advantageously be used for inserting the stepping sound insulation material 12. Here, the size of the stepping sound insulation material 12 is determined such that it corresponds to the distance of the laid foundation from the plate only in a stressed state. The stepping sound insulating material 12 is advantageously stuck on the bottom surface of the board. Thus, the formation of echoes, which is considered to be a problem in the field of parquet floors, is reliably avoided.

In fig. 2b, the two panels are shown in the installed state, but the right one of the panels 2 is shown without a rearward offset for the sake of clarity. The plate 2 rests with its bottom edge region on a strip-shaped support surface 5 and is glued to this.

In contrast to fig. 2a, step sound insulation 12 does not extend only in the vicinity of bearing surface 5, but also below the bearing surface, so that an insulation effect is produced in the region of bearing surface 5, which is illustrated by a dashed line, wherein the region below bearing surface 5 is indicated by reference numeral 13.

If minor irregularities or roughnesses in the surface of the laid foundation must be eliminated, for example when the concrete floor is rough, a bottom layer of flexible foam material, not shown, can advantageously be glued to the underside of the frame 1. The substrate may be applied in a spot or a surface.

As shown in fig. 4, the profiled plug-in part 3 of the frame sides 1c, 1d has a vertically upward shoulder 6, on both sides of which the plate rests in the laid state. The shoulder 6 is provided with a groove 7 in which a rubber seal 8, shown in cross-section in figure 6, is seated. If necessary, the seal 9 can also be glued to the shoulder 6 of the frame edge in the region of the groove, so that a projection is reliably avoided. It is also provided that the seal 8 is manufactured in a color that matches the color pattern of the plate. Therefore, there is no need to coordinate the color of the frame to the plates. The rubber seal 8 is mushroom-shaped, where the stem 8a of the seal 8 is configured such that it can be inserted into the groove 7 of the protruding shoulder 6. The cover part 8b is preferably trapezoidal and has a height such that its upper edge is approximately flush with the upper edge of a board 2 mounted in the frame in the laid state, as shown in fig. 2 b.

The width of the rubber seal 8 is larger than the width of the protruding shoulder 6 at least towards its upper end, so that in the laid state of the board the rubber seal is compressed and the effect of sealing the gap is obtained. At the corners, that is to say at the intersections of the plates, the rubber seals 8 are mitred at an angle of 90 degrees (fig. 3), as a result of which a sealing effect is also obtained at the intersections.

The profiled plug part 3 (fig. 4) comprises an extension 9 which corresponds to a correspondingly formed latching groove 11 (fig. 5) in the profiled plug part 4. The two profiled plug parts 3, 4 thus form a plug lock, by means of which a plurality of frames can be simply assembled together and can also be subsequently simply separated. In order to assemble these parts smoothly without cutting in situ, in each frame the extensions 9 are retracted with the locking projections 10 a distance X with respect to the outer edge of the frame.

As shown in fig. 1, each board 2 to be laid is provided with a frame. The frames are preferably glued to the underside of the board so that the board and the frames form one unit. Furthermore, the adhesive bonding has the advantage that the plates, when firmly fixed in the assembly of plates, are prevented from protruding even if the paved pavement is stepped on for a long time. For laying, the plates and the frame to be glued together are laid on the prepared foundation on which the pavement is to be laid (here the cement screeded ground) and spliced together, as a result of which the rim with the locking grooves 11 always butts against the rim with the locking projections 10. By assembling (locking) these parts, a mechanical connection is formed, which can then be disengaged again, as required. At assembly, the rubber seal 8 is also compressed to such an extent that a certain prestress is generated, as described above. With this prestress a sufficiently strong sealing effect against the ingress of dirt and moisture is ensured. In addition, the tolerances in laying the floor are eliminated.

Fig. 7 shows a further locking connection, in which the locking projection 10 projecting beyond the frame edge 1c has undercuts on its upper face and on its underside, which engage in a groove 11, which also has two undercuts, on the receiving frame edge 1 a. When the locking projection enters the locking groove, the locking groove is expanded and snaps back after it has fully entered and the side edge of the rim 1a rests against the side edge or shoulder 6 of the rim 1 c. The material elasticity is then chosen such that this can be done smoothly.

In fig. 8, the locking connection is formed without undercuts in the region of a projection 14 and a groove 15, so that only a guiding effect is provided here. The mechanical fixing is accomplished by a locking protrusion 10 on the bottom surface of the protrusion 14 and a locking concavity 11 in the lower sidewall surface of the groove 11. In addition, an engagement ramp 16 may be provided to simplify installation, as shown in phantom.

As can be seen very clearly in fig. 4, 5, 7 and 8, the female profile plug 4 acts on the underside of the male profile plug 3 over a length, that is to say according to the width of the shoulder 6.

Another embodiment of the present invention is shown in fig. 9. Here, in addition to the profiled rims 21a, 21b, 21c and 21d on the edges, a support frame 21 comprises reinforcing ribs 22, 23, of which a first set of reinforcing ribs 22 is parallel to the sides and a second set of reinforcing ribs 23 is diagonal. The reinforcing ribs 22, 23 cross each other so that a crossing point 24 occurs. These intersections may have different sizes.

On the profiled rims 21a, 21b, 21c and 21d, upper and lower projections 25, 26 are formed, which are half of the locking connection, i.e. the upper half locking connection and the lower half locking connection, respectively. This will be explained later. Each receiving region 27 defined by the profiled rims 21a, 21b, 21c and 21d and the reinforcing ribs 22, 23 has recesses which are indicated by dashed lines and whose function will be described later.

Fig. 10 shows a cross section of the support frame shown in fig. 9, wherein the profiled frame edges 21b and 21d in the edge regions can be seen. Furthermore, the course of the cross-piece 28 can be seen. The cross-piece 28 extends from the profiled rims 21a, 21b, 21c and 21d almost over the entire length or width of the supporting frame 21, but only on two adjacent side edges. Fig. 9 shows a crosspiece 28 arranged on the profiled rim 21a and a crosspiece 29 arranged on the adjacent profiled rim 21 b.

Also shown in fig. 10 are notches 30 and inner ribs 22. The upper and lower parts 25, 26 of the locking connection can also be seen.

In fig. 11 is shown the left side as section AA in fig. 9, the right side of fig. 11 corresponding to an adjacent panel according to the invention. First, the support frame 21 is shown with a profiled rim 21a, on which a plate 2 is mounted, which plate is furthermore held in place by a crosspiece 28 that acts as a stop.

The support frame 21 is provided with a notch 30 described later. On the outer surface of the support frame 21, an upper projection 25 is shown, which has a locking tooth 31 pointing downwards. The transition of the projection 25 to the profiled frame edge 21a is designed to be resilient, so that the projection 25 has a certain flexibility.

On the right in fig. 11, an adjacent bottom plate is provided, the edge structure of which corresponds to the section BB in fig. 9. The plate 2' rests on a profiled rim 21c, which has a lower projection 26 with a locking tooth 32. The plate 2 ' also overlaps the lower projection 26 at this time, so that the plate 2 ' rests on the upper projection 25 of the profiled rim 21a when the floor panels 21, 21 ' are assembled. On the left side of fig. 11, the mounting situation for the plate 2' is shown, where the lower projection 26 of the profiled rim 21c is located below the upper projection 25 of the profiled rim 21 a. In order for the upper locking projection 25 to still slide past the locking tooth, it is spaced from the plate 2 'such that the upper surface of the locking projection 25 is lower than the lower surface of the plate 2' or the resting surface of the plate.

The plates 2, 2' are held at a predetermined minimum distance from one another by the cross webs 28, wherein the seals 33 arranged on the cross webs 28 seal the plates against the upper surface. For this purpose, the seal 33 widens in a wedge-shaped manner in the upward direction and has a sealing lip 34, 34 'in the region of the tip, which lip extends toward the plate 2 or 2'. When the panels are assembled, the wedge-shaped end of the seal 33 comes into contact with a correspondingly formed bevel on the panels 2, 2' with a bevel and thereby causes a sealing effect. If moisture, such as sprayed-on cleaning liquid, still enters through this sealing surface, the sealing lips 34, 34' prevent further downward penetration.

In addition, the support frame 21 has a recess 35 on its underside, in which a sound-insulating profile 36 is arranged. The acoustic profile 36 protrudes beyond the lower edge of the profiled rim 21a and may have lateral balancing spaces 37, 37' which, under force, are able to deform the acoustic profile 36. In addition to the profiled frame 21a, the reinforcing ribs 22, 23 are also provided with sound-insulating profiles which engage in a groove, so that a good sound-insulating effect of the tread is achieved.

In fig. 12, a section along the line AA is also shown, but here the arrangement of the recesses 30, 30' and the supporting crosspiece 38 located therebetween can be seen. It is particularly expedient for the side walls of the transverse webs 38 to extend in such a way that the recesses 30 are enlarged from the receiving surface for the panels toward the bottom of the support frame 21. This allows the plate to be mechanically fixed in the support frame 21 by means of an adhesive passing through these notches 30. In this way, the plates, not shown, are also mechanically firmly joined to the support frame 21, since a honeycomb connection is present.

There is a distance between the bottom surface or gap 30 of the supporting crosspiece 38 and the bottom surface of the profiled rim 21 a. The application of glue to the top surface of the support rails 38 is accomplished mechanically, for example, with the aid of a squeegee. Alternatively, the back of the plate may be glued or both sides may be glued. Furthermore, it is not always necessary to bond the entire surface. In most cases it is sufficient that the partial surfaces are coated with glue, wherein the glue can also be applied in the form of glue lines.

As the adhesive, a thermoplastic glue, so-called hot melt glue, may be used, but also a one-component or multi-component reactive glue, in particular a PU glue with poor foaming properties, may be used.

The upper and lower projections 25, 26 are also visible in fig. 12, but these projections 25, 26 are not opposite the profiled frame edge 21a, but are displaced a distance into the drawing plane, as shown in fig. 9. But here too the engagement of the locking teeth can be clearly seen. It is to be noted here that the lower projection 26 is also resilient in order to enable the locking tooth to slide past. In this case, however, no additional space for escape is required, since it is a prerequisite that the entire panel can be lifted even when the locking connection is released. Thus, the disengagement of the locking connection can only be achieved if the upper locking projection bears directly on the underside of the plate.

Fig. 13 shows a part of the lower right corner shown in fig. 9. The course of the profiled frame edges 21a and 21d and the projecting cross webs 28 and the diagonally running reinforcing ribs 23 and the reinforcing ribs 22 running parallel to the profiled frame edges 21a can be seen here. The profiled frame edges 21a, 21d and the reinforcing ribs 22, 23 have a sound-insulating profile 36 which is injected into the groove 35 provided for this purpose via a central injection point 40 in the region of the intersection 24 after the production of the support frame in the first injection molding operation. Between the profiled frame edge 21a and the reinforcing rib 23, the receiving surface has recesses 30, 30' between which a support crosspiece 38 extends.

Fig. 14a again shows a section through the profiled rims 21a and 21d, wherein it can also be seen that only the profiled rim 21a is provided with a cross piece 28, which acts as a stop for the plate, while the profiled rim 21d does not have such a cross piece.

Fig. 15a shows a special embodiment of the seal 33. Instead of the sealing lip shown in fig. 11, a sealing projection 34 is provided, which projects into a groove on the edge of the plate 2, 2'. In the detail of fig. 15b it can be seen that the groove 41 can be completely larger than the sealing projection 34, as long as it is ensured that the sealing effect is at least locally produced. There is thus a sealing surface 42.

As mentioned above, the connection of the plate to the supporting frame is produced, for example, by means of an adhesive technique. A hot glue or a glue that hardens can be applied at this point, so that the glue passes all the way through the conically widening recess 30 and produces a mechanical fixing. The normal adhesive connection is present at the placement surface between the recesses, so that the plates are fixed in place after the glue has hardened not only by adhesive bonding but also by mechanical fixing in the form of a dovetail-type connection.

The support frame can be provided with a thermoplastic elastomer and a seal 33 for the step sound insulation 36 by a two-component injection molding method, it being possible to use a hard plastic material, such as polystyrene or polyurethane, for the frame itself, as step sound insulation, taking into account the thermoplastic elastomer TPE.

In addition, the locking teeth can be locked individually in the case of using a single projection, or in a plurality of locking engagements as described in the embodiments, so that the dimensional difference can be possibly eliminated. The locking connection is designed in such a way that, when the panels are lifted, the opposite edges are released by leverage. Whereas when the flat-laid panels are subjected to tensile stresses only, the detachment should only be possible after loads exceeding those normally used.

The advantage of the one-sided locking connection of the second embodiment is that the overall height is also significantly reduced compared to a plug connection.

Step sound insulation is embedded in the setting surface, in the embodiment, in the reinforcing ribs 22, 23 and the profiled rims 21a, 21b, 21c and 21 d. In this way, a lower structural height can also be achieved. The stepping sound insulating material can be constituted so that the anti-slip effect can be obtained.

The floor consisting of the panels and the supporting frame has an increased static strength due to the adhesive bonding, so that the required panel thickness can be reduced from the current 10 mm to 8 mm or even 6 mm in the case of granite panels. This results in considerable material and even cost savings in the manufacture of floor coverings.

As described above, the sound-insulating profiles 36 protrude beyond the bottom surfaces of the shaped frame rims 21a, 21b, 21c and 21d or the bottom surfaces of the reinforcing ribs 22 and 23, but here, the bottom surfaces of the shaped frame rims or the reinforcing ribs are also supported under high load and prevent damage to the stepping sound insulator. Therefore, the stepping sound insulating material embedded in the groove is not damaged when the load is high.

The glue itself is selected such that it has sufficient thermal stability when the floor heating system is in use. If the lay-up is to be done in outdoor areas, the glue must be resistant to weather attack.
