Description

The present invention relates to a protective element and covering system, in particular for use on modular roof systems.

Covering systems, particularly roof systems, by means of which a green roof surface can be created are already known from the state of the art. It is technically challenging to achieve the necessary stability and tightness of the covering system and at the same time a sufficient layer thickness of the soil and/or substrate layer, as well as a sufficient water absorption capacity of the covering system. In particular with modular covering systems, which are advantageous in terms of their versatility and easy assembly, there is still a great need for improvement in terms of the achievable planting depth, as well as the possibility of draining or storing excess liquid from the covering system in a controlled manner and thus ensuring the tightness of the covering system.

The object of the present invention is to achieve an improvement of the covering systems known in the prior art with regard to the achievable planting depth and the corresponding tightness and to prevent roots from penetrating the fastening section between elements of the covering system.

This object is achieved by a protective element according to claim 1 and a covering system according to claim 10. Further advantages and features of the invention emerge from the dependent claims.

According to the invention, the protective element has a holding section and at least one leg, the holding section having a cross-section defined perpendicular to a longitudinal axis, which forms a receiving space, the at least one leg being integrally formed on a lateral end of the holding section or being fixed to it in a materially bonded manner or being fixed in a form-fitting manner, the holding section and the at least one leg extending with a substantially constant cross-section along the longitudinal axis, the extension of the protective element parallel to the longitudinal axis being a multiple of its extension transverse to the longitudinal axis. The protective element is, to put it simply, a cover element which extends elongatedly along a longitudinal axis and which is designed in particular to engage, cover and protect a fastening section of a cover system. The protective element is in particular intended to protect the fastening section of a cover system, in particular the area in which two elements of the cover system are fixed to one another, against environmental influences. Furthermore, the protective element preferably contributes to ensuring a controlled drainage of water, in particular in the case of ice formation and/or stagnant water formation when there is planting on the roof system. In particular in the case of so-called ice embankment formation, the protective element according to the invention ensures that any meltwater that occurs does not reach the connecting area between two surface elements of a covering system. Furthermore, the protective element fixes the plant substrate and protects the fastening section against the penetration of roots. According to the invention, the holding section of the protective element is closed in three spatial directions and is designed to be placed on a fastening area of a covering system or to be pushed onto it. The essentially constant cross-section of the protective element along or parallel to its longitudinal axis advantageously allows the profile to be produced by means of extrusion and the profile to be pushed onto the fastening section of a covering system along the longitudinal axis. However, within the scope of the present invention, smaller projections for local engagement on the fastening section, which represent deviations from the constant cross section along the longitudinal axis, can be provided on the protective element, in which case its cross section is still defined as essentially constant despite these deviations. In a first embodiment, the at least one leg of the protective element is designed as one piece with the holding section. A one-piece design of the protective element facilitates its manufacture and improves the strength thanks to optimized stress distribution in the homogeneously distributed material in the protective element. Alternatively, the leg is preferably fixed to the holding section in a form-fitting manner, for example by connecting by clinching as known in the prior art. Particularly preferably, as an alternative or in addition to the form-fitting connection, a material-fitting connection, for example by gluing, can be provided. This combination of features makes it possible in particular to use different materials for the leg and the holding section. This makes it possible to allow relatively high water levels in a plant substrate arranged on a covering system without there being a risk that this water will get directly into the connection area of the surface elements. Advantageously, the protective element is an elongated profile body with an extension length parallel to the longitudinal axis, which is substantially greater, preferably more than ten times and particularly preferably more than twenty times the extension in the other spatial directions.

The holding section advantageously has an undercut acting perpendicular to the longitudinal axis, wherein the holding section is open in the area of the undercut. The holding space arranged in the holding section of the protective element forms an undercut which allows a positive fastening of the protective element to a covering system. The undercut can preferably be formed by an inwardly projecting web. Alternatively, the wall of the holding section, viewed in cross section, is preferably curved or bent in such a way that an undercut acting perpendicular to the longitudinal axis is formed. In addition or as an alternative to fastening the protective element to the fastening section by means of an undercut on the holding section, the protective element can have at least one holding flange extending transversely to the direction of extension of the at least one leg, which is held by the plants and/or the plant substrate of the covering system and thus secures the protective element.

Advantageously, the at least one leg is shaped at least in some areas in such a way that a channel is formed. The channel is advantageously formed between the leg and a part of a covering system. In a first embodiment, the channel is formed as a cavity which serves to drain water and in particular reduces the capillary effect between the protective element and the covering system in such a way that no water is sucked or drawn between the protective element and the other parts of the covering system. Alternatively, the channel is preferably filled with sealing material which achieves a seal through the protective element and particularly preferably protects the connecting area of two surface elements against the ingress of liquids and foreign bodies.

In a preferred embodiment of the protective element with two legs, it can be advantageous if only one of the legs forms a channel. This advantageously results in an asymmetrical design of the protective element in relation to a vertical plane in which the longitudinal axis lies. This embodiment makes it possible to equip the protective element with a channel and/or a sealing section on just one side, whereby the other side can be designed to save particularly little material. The channel is preferably formed on the leg that is on the side of the connection area between two surface elements, on which at least one distal end of the surface element is arranged, next to which liquid could penetrate into the connection area.

In a preferred embodiment of the protective element, it has only the first leg on the holding section, with the distal end of the holding section opposite the first leg preferably forming an undercut acting perpendicular to the longitudinal axis, which is designed for positive engagement with the connecting area of two surface elements. The single-leg design of the protective element is particularly material- and therefore cost-saving, since a second leg can be dispensed with. The leg and the associated protective function of the protective element is preferably arranged on the side on which the connecting area of two surface elements is open, in order to prevent water from entering this connecting area.

In an alternative preferred embodiment, the protective element has two legs, one of which is arranged and formed on a lateral, distal end of the holding section. In this embodiment, the protective element is advantageously designed to be plane-symmetrical to a plane in which the longitudinal axis lies. The area between the legs is advantageously designed in such a way that at least one channel is formed. This at least one channel for draining fluid and foreign bodies is advantageously delimited on one side by the leg and on the other side by a support element of a covering system to which the protective element is advantageously fixed. In an alternative embodiment, the protective element is designed to be used on the edge of a covering system, whereby only one leg is required. In this case, a channel is formed between the leg and the edge of the covering system. The protective element is supported via its holding section on the edge of the covering system, particularly preferably on one of the surface elements. It is understood that the features described below for a protective element with two legs are also applicable to a protective element with one leg, where this is not excluded for technical reasons.

Furthermore, the first leg preferably has an extension along a first leg axis, wherein the second leg has an extension along a second leg axis, wherein the first leg axis and the second leg axis are at an angle to each other, wherein the angle is greater than 10°. The legs extend at least at their distal ends along a leg axis, wherein the leg axes enclose an angle which is greater than 10°. In this embodiment, the plant substrate placed on the cover system advantageously presses the legs of the protective element in such a way that against the surface elements, that a seal takes place between the legs and the respective surface element. Furthermore, in this embodiment, the protective element itself, in addition to its fixation via the holding section on the fastening section of the cover system, is also held by the engagement of the plant substrate on the legs and the weight of the green roof applied to the cover system. In addition, the legs in this embodiment ensure that a sufficient channel cross-sectional area is formed between the support element and the respective leg. In this way, the drainage of fluid and foreign bodies is always guaranteed. Preferably, the angle spanned by the legs is greater than 10°, particularly preferably greater than 20°. Due to the inclination of the legs relative to one another, on the one hand, a sufficient channel cross-sectional area is ensured and, on the other hand, the weight of the plants creates a stronger holding force, which holds the protective element to the cover system.

The first leg advantageously has an extension along a first leg axis at least at its distal end spaced from the holding section, the second leg having an extension along a second leg axis at least at its distal end spaced from the holding section, the first leg axis and the second leg axis being substantially parallel to one another and spaced from one another, the first leg having a first sealing section and a first line section, the second leg having a second sealing section and a second line section, the line sections being further apart from one another than the sealing sections. In this embodiment, the legs extend substantially parallel to one another, a sufficient channel area being provided by means of two line sections, which are designed as local markings on the legs. In the present case, an extension substantially parallel to one another means that the predominant extension of the legs runs parallel to the plane that lies between the legs. This plane is preferably the plane of symmetry, to which the protective element is preferably designed to be plane-symmetrical. The legs particularly preferably have a sealing section at their distal end, which is designed to come into contact with a support element and/or a surface element, with the sealing section of the protective element resting as fully as possible on the other component of the cover system creating a seal. The line section of the respective leg is advantageously provided below or above the respective sealing section. It is understood that within the scope of the present invention, a design of a part of a leg with an inclined position can be combined with a line section and a sealing section. Starting from the holding section, a line section is advantageously provided on the leg, to which a sealing section adjoins, with an area being provided below the sealing section, which extends at an angle to the plane of symmetry of the protective element. In this way, the previously described advantages of the individual variants can be combined with one another.

The holding section is advantageously shaped as a hollow cylinder cutout. In other words, the holding section has a substantially cylindrical outer and inner surface. The cylinder is designed to be open on one side, with the legs being formed on the holding section on this open side. The cylindrical shape of the holding section on the inside is particularly suitable for engaging in a fold area of two sheet-like surface elements, which has a substantially cylindrical outer surface. In addition, a partially hollow-cylindrical design of the holding section is particularly suitable for elastic bending, minimizing the risk of notch effects at heavily loaded points on the holding section.

The protective element is preferably made of elastically deformable plastic, preferably PTFE, or of metal, preferably aluminum or precious metal. A protective element made of plastic, preferably PTFE, reduces the manufacturing costs of the protective element and allows a particularly lightweight construction of the file covering system equipped with this protective element. In addition, the elastic plastic is easily deformable, so that the protective element can be mounted on a covering system without technical aids, by simply pressing it on. Alternatively, the protective element is preferably made of an elastically deformable metal, in particular an aluminum alloy. It has been shown that aluminum is a very practical and weather-resistant, as well as radiation-resistant material, in the area of roof systems. The fastening section of a covering system can be additionally reinforced with a protective element made of an aluminum alloy, whereby the service life of the protective element is essentially the same as the expected service life of the entire covering system.

Advantageously, at least one leg has a retaining knee, which forms an outwardly projecting projection. The retaining knee of the leg is in particular an outwardly projecting projection, which is designed to engage positively with a substrate or a corresponding planting mat. In this way, the protective element ensures that the elements for planting are held even in windy conditions. In addition, the retaining knee can be combined with the likewise preferred feature of a previously described line section. Advantageously, the protective element has a wall thickness that is essentially constant over its entire cross-section. It is understood that in this case an outwardly projecting area, such as the preferred retaining knee, simultaneously also means a cavity formed on the inside of the protective element, which can be used, for example, as a channel for draining accumulated water. In a particularly preferred embodiment, the retaining knee is designed in the shape of a barb, such that plant substrate can easily be pushed from above the protective element in the direction of the covering system, whereby movement of the plant substrate in the opposite direction is prevented or made more difficult by the barb shape of the retaining knee.

According to the invention, a covering system is also provided, comprising a first surface element and a second surface element, wherein the first surface element and/or the second surface element is fixed at least in a form-fitting manner in a fastening section on a support element, wherein a protective element is provided which can be fixed in the fastening section on the first and/or on the second surface element in such a way that the protective element at least partially surrounds the first and/or second surface element in the fastening section with a holding section, wherein the protective element has at least one leg, wherein the leg is arranged at a distance from the support element in such a way that the fastening section is protected against the ingress of water and foreign bodies. In a further preferred embodiment, a channel is formed between the leg and the support element. The covering system is preferably a roof system which is constructed from sheet-metal surface elements and support elements provided in the connecting region of the surface elements. The surface elements are advantageously provided with bevels or folds, which increases the torsional rigidity of the entire covering system. The respective surface element advantageously has a shape with a substantially flat central surface and sections that project vertically or upwards at the lateral ends. At the distal ends of the vertically projecting sections, a folded connection is made between the first surface element and the second surface element around a support element. The surface elements are advantageously assembled to form a covering system by plastic deformation at their respective distal ends, overlapping one another and enclosing an end section of the support element. The positive connection of the surface elements to one another and to the support element created by the plastic deformation ensures a particularly stable roof construction. In order to achieve sealing and protection of the fastening section on a covering system designed in this way and at the same time to drain off the excess water collected on the covering system, a protective element is provided which is attached to the fastening section. The protective element essentially surrounds the fastening section and at least one of the surface elements with a holding section in a form-fitting manner. The at least one leg formed on the protective element forms a channel in which fluid can be collected and drained along the longitudinal direction of the protective element. Thanks to the protective element provided on the cover system, it is possible to significantly increase the planting height on the cover system, i.e. to use a thicker substrate, which allows a greater root depth of the plants applied to the cover system. The layer thickness of the planting substrate can even exceed the height or the extension of the support element and the surface elements in the vertical direction, since the protective element ensures that no water can penetrate into the fastening section from above and at the same time the water that would penetrate from below is drained via the channel. It goes without saying that in order to successfully drain excess water through the channel, a certain inclination of the entire cover system is preferred. The protective element also ensures that roots that could penetrate into the fastening section of the surface elements and cause permanent damage or even bending of the folded surfaces of the surface elements are diverted.

Advantageously, a protective element with the features described above is fixed to the cover system as a protective element. It goes without saying that the advantageously described features of the protective element are particularly effective in interaction with the other components of a cover system.

Preferably, the legs are spaced apart from each other in such a way that at least one channel is formed between the legs, which channel is used to drain fluid and foreign bodies along the Longitudinal axis is suitable. In the preferred embodiment of the protective element with two legs, a channel is formed on each side of the fastening section. Thus, in the region of the first surface element, between the first leg of the protective element and the vertical surface of the surface element and/or the support element, a first channel is formed. In addition, in the region of the second surface element, between the second leg of the protective element and the corresponding vertical wall of the surface element and/or the support element, a second channel is formed.

Preferably, the angle spanned by the leg axes is greater than 10°, particularly preferably greater than 20° and particularly preferably greater than 30°. It goes without saying that the more obliquely the legs of the protective element are aligned, the greater the weight of the plant substrate causes the legs to be pressed directly against the respective surface element. At the same time, however, the protective element is designed to be more expansive at a larger angle and, in case of doubt, can be less easily removed from a covering system in order to be replaced, for example, by a newer protective element.

The holding section and/or the legs are advantageously pre-tensioned against the support element. Particularly preferably, by pre-tensioning the holding section and/or the legs against the support element, a positive connection can be achieved between the protective element and the composite of support element and surface elements before the plant substrate is introduced into the area of the cover system. In this way, the assembly of the cover system is made easier and the protective element is prevented from accidentally detaching from the fastening section. It goes without saying that the protective element can advantageously be mounted on the fastening section by pressing it vertically by hand. Alternatively, the protective element, particularly in an aluminum version, is pushed onto the fastening section along the longitudinal axis.

This in 1 The cover system shown has a first surface element 2, a second surface element 4, and a support element 6. The support element 6 has a fastening area designed as a local thickening, around which the respective upwardly projecting sections of the surface elements 2, 4 are laid and are plastically deformed in this area in such a way that a positive connection is established between the surface elements 2, 4 and the support element 6. This section of the cover system, defined as fastening section B, is surrounded by a protective element 8. The protective element 8 has a holding section 82 which is essentially adapted to the shape of the fastening section B and thus forms a particularly firm, positive connection with the fastening section B. In particular, the holding section 82 of the protective element 8 preferably has a receiving space 82A which forms an undercut which acts against displacements transverse to the longitudinal axis A. In other words, the inner diameter of the receiving space 82A of the holding section 82 is larger than the arcuate region provided at its lower end, in which the distance between the two inwardly projecting surfaces of the concavely shaped region of the protective element 8 is smaller. 1 In the embodiment shown, the protective element 8 has a first leg 84A and a second leg 84B, wherein the legs 84A, 84B each extend along a leg axis S1, S2. The leg axis sen S1, S2 span in a plane orthogonal to the longitudinal axis A (section plane in 1 ) form an angle α with one another, which is preferably greater than 10°, particularly preferably greater than 20°. It is understood that the effect of a weight force or pressure force on the outward-facing surfaces of the legs 84A, 84B causes the legs to be pressed together, whereby at the same time the holding section 82 also comes into a firmer form fit with the fastening section B. The protective element 8 is therefore preferably additionally secured to the fastening section B by introducing plant substrate onto the covering system. This has the particular advantage that the installation of the protective element 8 is relatively easy, while an unintentional detachment of the protective element 8 once the planting is complete is only possible with a great deal of force. This achieves a particularly strong connection between the protective element 8 and the usual components of the covering system.

2 shows a perspective view of another preferred embodiment of a protective element 8. In contrast to the 1 In the embodiment shown, the leg axes S1, S2 are not at an angle to one another, but run essentially parallel to one another. In this embodiment, legs 84A, 84B are formed on the protective element 8, adjacent to the two lateral ends of the holding section 82, which are each essentially straight and run downwards. The legs 84A, 84B preferably each have a line section 86A, 86B, to which a sealing section 85A, 85B is connected. The power areas (line sections) 86A, 86B are preferably further apart from one another than the sealing sections 85A, 85B. In practice, this embodiment results in the fact that when the legs of the protective element 8 are prestressed against a support element 6 arranged between them or one of the surface elements 2, 4, only the sealing sections 85A, 85B come into contact with the support element 6, while the line sections 86A, 86B each form a channel K on each side of the support element 6. It is understood that a combination of the embodiments of the 1 and 2 For example, preference is still given to the lower end of the 1 shown, oblique legs 84A, 84B each have an inwardly projecting sealing section 85A, 85B, which can come into contact with the support element 6 and particularly effectively prevents roots from penetrating the fastening section B. The sealing section in 2 The receiving space 82A of the holding section 82 shown is essentially cylindrical. The cylindrical shape of the receiving space 82A is particularly optimized for attachment to a surface element 2, 4 provided with a curve.

3 shows an embodiment of the protective element 8, which corresponds to 2 shown embodiment. In the transition area between the respective line sections 86A, 86B and the sealing sections 85A, 85B, a retaining knee 87 is provided, which is designed in particular to hold a plant substrate or a planting inserted into the cover system. The barb-shaped outer geometry of the retaining knee 87 ensures simple assembly or insertion of plant substrate into the cover system, while an unintentional lifting of the plant substrate by the retaining knee 87 is essentially prevented.

4 shows a further, preferred embodiment of the protective element 8, in which a combination of the oblique parts of the legs 84A, 84B and the vertically provided parts of the legs 84A, 84B are provided. Line sections 86A, 86B, adjoining retaining knees 87 and sealing sections 85A, 85B formed underneath these are advantageously formed on the legs, with dovetail-shaped sections being formed at the lower end of the sealing sections 85A, 85B, which extend obliquely downwards at an angle to one another. The oblique parts of the legs 84A, 84B essentially function as a sealing lip, which deflects water and roots and thus protects the fastening section B and the area inside the protective element 8 particularly effectively.

The 5 to 9 show various preferred embodiments of a protective element 8 according to the present invention. The protective element 8 according to 5 is similar to the protective element 8 according to 3 , wherein at the distal end of the sealing sections 85A, 85B there is provided a dovetail-like protruding, oblique part of the leg 84A, 84B, which is particularly designed to hold a plant substrate.

In the 6 The embodiment of a preferred protective element 8 shown preferably has web-like protruding retaining knees 87, which ensure that the protective element 8 is held against displacement both upwards and downwards relative to the plant substrate. The sealing sections 85A, 85B thereby achieve a preferably full-surface contact with the first surface element 2 or with the second surface element 4.

At the 7 shown preferred embodiment of the element 8, are similar to the Embodiment of 6 , web-like, outward-projecting retaining knees 87 are provided. At the same time, the upper part of the legs 84A, 84B is designed to taper obliquely in the direction of the sealing sections 85A, 85B.

The 8th and 9 The embodiments of the protective element 8 shown differ from the previously explained embodiments in particular in that the holding section 82 of the protective element 8 does not form an undercut. In this embodiment, it is therefore preferred that the protective element 8 is held on the cover system via a first holding flange 88A and a second holding flange 88B. In particular, the plant substrate and the plants themselves preferably press with their weight on the holding flange 88A, 88B and thus hold the protective element 8 in its position. At the same time, the preferably large contact surface of the holding flange 88A, 88B on the surface elements 2, 4 forms a sealing surface which prevents liquid and roots from penetrating the interior of the protective element 8.

The preferred embodiments of the 10 and 11 show the protective element 8 without channel K and instead closely fitting the surface elements 2, 4, which results in a good seal and stable form-fitting fixation at the fastening section. The 11 The preferred embodiment shown with only one leg 84A is particularly light and material-saving.

The 12 and 13 The preferred embodiment of the protective element 8 shown is asymmetrical and shown in two installation directions. The asymmetrical design of the protective element 8 allows the channel K to be arranged specifically on one of the sides of the fastening area B and to save material and weight on the other side. In this way, optimal sealing, water drainage and protection against the penetration of roots can be combined with the preferably low weight of the side of the protective element 8 without channel K and sealing section 85A, 85B.

In the 14 The preferred embodiment of the protective element 8 shown is an asymmetric variant of the one already shown in 8th illustrated protective element 8. Instead of the second leg 84B, only a rounded section of the holding section 82 is provided, which forms an undercut for positive fixing to the fastening section B of the surface elements 2, 4.

The 15 and 16 show a preferred asymmetrical variant of the protective element 8 and an alternatively preferred plane-symmetrical variant of the protective element 8, each with at least one sealing section 85A, 85B, which is equipped with a rubber element or with a pasty filling or a foam section. An adhesive is advantageously provided on the sealing sections 85A, 85B for the material-locking sealing against at least one of the surface elements 2, 4. The 16 The embodiment shown combines a sealing section 85A, 85B with a channel K formed on each of the legs 84A, 84B in a particularly compact manner, which is considered to be particularly safe against the ingress of waterlogging and water.

In the 17 The embodiments of a protective element 8 shown show various possibilities for designing the holding section 82. These preferred variants of the cross-sectional geometry of the holding section can be used in any of the previously shown embodiments of the 1-16 For example, in order to facilitate the manufacture of the protective element 8, the holding section 82 can have a rectangular shape, which preferably allows a channel K for draining water to be formed in the head region of the protective element 8. Alternatively, a hexagonal basic shape, an elliptical basic shape or a rectangular basic shape with an inwardly projecting web, which provides an undercut on the holding section 82, can be provided on a protective element 8 according to the present invention.
