Description

Integrated roof system, attachment of insert profiles on sandwich panels with undercut grooves

The present invention relates to the provision of profiled plate-like plates, which are used in particular as a building envelope. The structure of profiled sheet-like plate is suitable to attach objects without drilling through the plate.

Profile sheets are well known and often find use in roofing systems of buildings, especially industrial buildings. In this case, corrugated sheets or conventional trapezoidal sheets are often preferred for a long time. However, these have the disadvantage that an attachment of any objects, such as the attachment of solar modules, only via a penetration, ie a through hole, the profile sheet and thus the building envelope is possible. If the attached object is then to be removed again, then boreholes remain in the profiled sheet often can only be sealed at great expense.

For fastening objects without damaging the profile sheet or the building shell, profiled sheets have been developed in recent years, the webs of which in some cases have a cross-section in dovetail shape. The shape of adjacent webs can alternate between trapezoidal shape and dovetail shape. For the attachment of objects to such profiled metal sheets there are fastening elements which are screwed in such a way that a lower part engages around the dovetail-shaped web and an upper part is connected to the object to be fastened. The attachment by means of such fasteners leads, especially in the attachment of elongated and / or widely extended objects, to stability losses and the risk of bursting of the fastened objects due to large forces.

The object of the present invention is now to provide a profiled sheet-like plate which makes it possible to fasten objects without penetrating the profiled sheet and in particular to stabilize elongate or extended objects by utilizing a self-locking effect.

Starting from the prior art, it is therefore the object of the present invention to provide a profiled plate-like plate which eliminates the above-mentioned problems in the attachment of objects to profile sheets known from the prior art.

This task is formed by the profile-like The panel of claim 1, the sandwich panel of claim 10 and the building envelope of claim 11. Advantageous developments of the profiled sheet-like plate according to the invention and the building envelope are given in the respective dependent claims. Furthermore, in claims 16 and 17 advantageous uses of the profiled sheet-like plate according to the invention, the sandwich panel and the building envelope are called.

According to the invention, a profiled plate-like plate for the interior or exterior cladding of buildings has a plate plane from which at least two first webs extending parallel in a first direction protrude. The at least two first webs have a predetermined web height in a second direction, which is perpendicular to the first direction and to the disk plane. Furthermore, the profiled plate-like plate has at least one elongated protuberance from the plate plane, which runs substantially parallel to the first webs. The protuberance is preferably arranged between the at least two first webs. The protuberance has a maximum of the plate plane remote area, which is seen from the plate level below the web level. This means that the at least one elongate protuberance protrudes in the direction of the second direction from the plane of the plate, wherein the maximum distance from the plate plane area between plate plane and a plane which is given by the web heights of the at least two first webs, or that protruding at least one protuberance in a direction opposite to the second direction of the plate plane, wherein the maximum of the Plate level removed portion of the protuberance on the at least two first webs opposite side of the plate plane. The at least one elongated protuberance from the plane of the plate can accordingly be a groove or a web. According to the invention, at least one of the at least one protuberance is formed as a groove which is undercut at least on one side in the longitudinal direction of the protuberance or at least one undercut undercut on one side. In other words, this means that the cross section of the protuberance has at least one undercut perpendicular to the plane of the plate.

In the case of the profiled plate-like plate according to the invention, the at least two first serve

Webs and the at least one elongated protuberance not only the stability of the profile surface like plate itself, but also the stabilization of possibly to be fixed elongated or extended objects. Thus, the profiled plate-like plate on a mounting plane, which is arranged parallel to the plane of the plate in the region of the undercut of the protuberance. Furthermore, the areas of the at least two first webs which are at a maximum distance from the plane of the plate form a supporting plane. With the aid of fastening elements, the first region of which engages or engages around the at least one protuberance in a positive and / or positive engagement and whose second region is connected to the object to be fastened, in particular elongate objects can be placed on the support plane and with the aid of the Fastener are pulled in the direction of the mounting plane, so that they are in constant contact with the maximum of the Plattenebe- ne remote areas of the at least two first webs. With the help of the profiled plate-like plate high pressure forces, for example due to snow loads, can be taken up by the at least two first webs and introduced into the substructure. Thus, the plate according to the invention has a large number of load application points. In addition, the distance between the fastening elements in the protuberances, defined by the maximum web height, leads to self-locking, for example in the case of roof-parallel loads, so that, for example, slippage of the object is prevented. Furthermore, a ventilation of the attached objects is guaranteed.

Preferably, the profiled plate-like plate according to the invention is attachable to a building in such a way that the first webs protrude out of the plane of the plate in the direction of an object to be fastened. In the case of attachment of the object to a building exterior wall or a roof top, the profiled sheet-like plate according to the invention is aligned such that the webs outwardly, in a direction away from a building or a building wall or a roof top, emerge from the plane of the plate. In this case, the second direction is to be defined as the direction away from the building wall or the roof or towards the surroundings.

Preferably, the formed as a groove or web at least one protuberance is formed as a bead. Inventive profile-like plates can be produced easily and inexpensively, for example by means of a roll forming. The profiled sheet-like plates are thus preferably formed two-dimensionally. The at least one protuberance preferably has a cross section in the form of a dovetail or a drop. Alternatively, the cross section of the at least one protuberance may also be T- or L-shaped. Alternatively, the cross section of the elongated protuberance may also have the shape of a two-dimensional geometric body selected from the group consisting of rectangle, trapezium, tri or polygonal, circular sector, circular segment, ellipsoidal sector, ellipsoidal segment or combinations thereof. It should be noted, however, that the two-dimensional geometric body describing the cross-section is oriented such that the cross-section of the protuberance has at least one undercut. For example, if the shape of a rectangle is chosen, make sure that parallel sides are not aligned parallel to the plane of the plate. In individual cases, however, pin-shaped or rectangular protuberances without undercut are also advantageous.

By contrast, the cross section of the at least two first webs is preferably trapezoidal and has no undercut. However, the cross section of the at least two first webs may also have one or more undercuts and be in the form of a dovetail or a drop. Likewise, the cross-section may take the form of a two-dimensional geometric body selected from the group consisting of rectangle, rhombus, trapezium, triad or polygon, circular sector, circular segment, ellipsoidal sector, ellipsoidal segment, and combinations thereof. The orientation of the two-dimensional geometric body, which indicates the shape of the cross section of the first webs, is in this case Ie negligible.

The profiled sheet-like plate according to the invention leaves open the possibility that at least two of the at least two first webs have different cross-sections. Thus, there is the possibility that the profiled plate-like plate has a number of first webs, wherein adjacent webs or by an elongated Ausstül- pung separate first webs have different cross-sections. In addition, the first webs may be formed so that adjacent first webs have different cross sections, while separated by a protuberance first webs each having a same cross-section.

It can vary not only the cross section of the first webs, but also the height of the webs. Thus, at least one of the first webs, for example, have a lower web height than the other first webs. The web with the smaller web height then only contributes to the stability of the disk itself, since its maximum distance from the disk plane area seen from the disk plane below the support level. A profiled sheet-like plate according to the invention with a series of first webs can be designed so that at least two of the first webs have a maximum web height and thus form the support plane. The remaining first webs may have a smaller web height. The first webs with the lower web height can be arranged in a certain regular or non-regular order around the first webs with the maximum web height and the at least one protuberance. Preferably, the web height of the at least two first webs coincides with the maximum web height, so that the support plane, which is formed by the maximum of the plate plane remote areas of the webs with maximum web height, parallel to the plate plane. In individual cases, however, the support plane can be clamped by two first webs with different web height, so that the support plane no longer runs parallel to the plate plane.

The profiled plate-like plate according to the invention preferably contains at least one metal and / or at least one polymer material and / or at least one fiber material or consists of one of these materials. Alternatively, inventive profiled plate-like plates may also be made of wood or glass.

Preferably, the profiled plate-like plate is a profiled sheet. It can either consist of or contain a single arbitrary metal or a mixture of several metals. The metal used is preferably aluminum, steel or stainless steel. Profiled sheet-like plates containing at least one metal are preferably produced by roll forming and sawed off to a desired length. In individual cases, production of the plates according to the invention by extrusion is possible.

Alternatively, the profiled plate-like plate can also be made of one or more polymeric materials and / or of one or more fiber composite materials. In this context, polyvinyl chloride (PVC) and / or other witte- Resistant plastics particularly suitable. Extrusion processes, but also casting processes or rolluraforming processes, are preferred for the production. In addition, a plate made of plastic according to the invention can be deep-drawn.

The profiled plate-like plate may have a coating. This coating can serve, for example, as corrosion protection and is preferably attached to at least one side of the panel forming a building exterior. Preferably, the plate side, which faces outward or points in the second direction and thus has at least the first webs, the building exterior. A coated profiled plate-like plate can, for example, be painted, anodized, printed, galvanized or powder-coated. Furthermore, a plate formed like a profiled plate can not only be made up of a layer, in particular a sheet, but it can have several layers. These layers can be pressed or glued together. The individual layers may have the same or different materials and the same or different thickness.

The plate according to the invention preferably has an extension of several square meters. Thus, the plate preferably has a length in the first direction in the range of 1 m and 25 m, in particular in the range of 3 m to 18 m, a width perpendicular to the first direction in plate plane in the range of 0.3 m to 3 m, in particular Range of 0.5 m to 2 m, preferably a width of 1 m, and a height perpendicular to the plane of the plate in the range of 2 cm to 40 cm, in particular in the range of 5 cm to 30 cm, preferably a height of 10 cm. The height is determined sen if the elongated protuberance is a web, or the distance between the support plane and the plane which is spanned by the maximum of the plate plane remote areas of the protuberance, if the protuberance is a groove. Depending on the roof length between eaves and ridge, the length of the plate according to the invention may deviate from the values given above.

A sandwich panel is to be understood as a layer sequence, wherein a lower outer layer and / or an upper outer layer is formed as a sheet metal or plastic layer and in the middle of which there is an intermediate layer. The upper outer layer and / or the lower outer layer are formed according to the invention as profiled sheet-like plate. The intermediate layer is preferably filled with foam, so that a high carrying capacity is achieved with simultaneously high thermal insulation. Depending on the need, the upper outer layer and / or the lower outer layer may thus have the structure of a profiled plate-like plate according to the invention. If the sandwich panel serves, for example, as a building wall, depending on the design of the sandwich panel, objects can be fastened on the inside or the outside of the building wall.

The profiled sheet-like plate used as the outer upper and / or outer lower layer is preferably arranged in the sandwich panel such that the first ribs protrude in a direction away from the intermediate layer from the panel. If, for example, the outer upper layer forms the outside of a building, the first webs of the outer the upper panel to the outside, in one direction away from the sandwich panel and thus away from the wall or roof.

According to the invention, a building envelope with suitability for fastening objects has at least one profiled sheet-like plate according to the invention or a sandwich panel according to the invention. The term "building envelope" is preferably the roof cover and / or the cladding of walls to understand.

The profiled plate-like plate or the sandwich panel according to the invention is preferably, in particular in the case of an external building envelope, integrated into the building envelope in such a way that the first webs protrude outwards, in the direction of the building environment or the sky and away from the building, out of the plane of the panel.

For attachment of objects, the building envelope preferably has at least one fastening element. This fastening element contains at least one gripping element for positive and / or non-positive engagement in the at least one protuberance and / or for positive and / or non-positive gripping around the at least one protuberance of a profile surface-like plate, a holding element with a region for holding an object and a connecting element for screwing and / or for clamping and / or for clamping the gripping element with the holding element. Such fasteners are available partially prefabricated.

Does the building shell, for example, profiled sheet-like plates or sandwich panels, wherein the at least one protuberance of each plate is a groove, the gripping element is preferably formed as a first sliding block with a first screwed bolt. On the other hand, if the protuberance is configured as a web, then the gripper element is designed as a web clamp with a first screwed-in bolt. The bolt preferably has a thread or an undercut on its side facing away from the first sliding block or the web clamp side. The gripping element can be formed in one or more parts. The gripping element can thus for example also be a screw with a correspondingly shaped head.

Does the object to be fastened have a groove-shaped

Undercut on how, for example, the insertion profile of a solar module has a groove, the retaining element is preferably formed as a second sliding block with a second screwed threaded bolt. The second threaded bolt has a thread or an undercut on its side remote from the second sliding block. The second sliding block can thus be inserted into the groove-shaped undercut of the object for attachment, i. inserted or screwed. The retaining element can also be formed in one piece as well as in several parts.

Alternatively, the holding element can be designed as a second web clamp, wherein a second bolt, as has already been described above, is screwed into the second web clamp.

The connecting element of the fastening element can be designed as a nut with right-left thread or union nut and allows screwing of the gripping element with the holding element. Alternatively, a snap or tension lock can serve as a connecting element.

A further possibility for training the fastening element proposes as a gripping element a first sliding block or a first web clamp which can be screwed or clamped parallel or perpendicular to the first direction, as a holding element a second nut stone or a second web clamp and as a connecting element a threaded bolt, which on his has a thread at both ends. With the help of the threaded bolt, the gripping element and the holding element can be screwed together.

Another embodiment variant of a fastening element proposes an angle, which is slotted on top and fastened by screwing on the insertion profile and rests on the bottom of the profiled plate-like plate and is screwed or clamped in the protuberance of the plate.

The attachment of objects by means of such fasteners is simple and vorzugswei- se only the use of a wrench. In addition, the dismantling without affecting the building envelope and even a reuse of fasteners is possible.

The length of the first and the second threaded bolt is preferably selected so that the threaded bolts abut each other when tightening the connecting element, in particular the nut, and so the distance between the plane of the plate plate-shaped plate or the sandwich panel and an elongated object to be fastened is precisely defined, so that over-rotation of the screw connection and a resulting deformation of the insertion profile or even tearing of the grooves is avoided. By virtue of such a design of fastening element and plate or sandwich panel formed as a profile plate, the fastening elements only have to absorb tensile forces from wind suction loads, whereas the pressure forces from wind suction and snow loads over the first webs have a maximum web height of the profiled sheet-like plate or sandwich panel can be initiated in the substructure.

The second sliding block of the fastening element for fastening objects to building envelopes is preferably designed such that it engages positively and / or positively in a groove-shaped undercut on an object to be fastened, in particular in the groove of an insertion profile for solar modules. For fixing a typical insert profile for a solar module, the width of the second sliding block is in the range of 20 mm to 80 mm, in particular 60 mm, and the height of the sliding block in the range of 2 mm to 10 mm, in particular 6 mm.

The attachment in particular of insertion rails for solar modules of the present invention profiled sheet-like plates, sandwich panels and building envelopes according to the invention is particularly advantageous because the insertion rails can be fixed at a desired distance, which is tuned to the extent of the solar module, and thus sufficient a single-layer substructure. A further advantage is a low construction height of the solar modules on the support level. The solar modules are preferably located at a distance corresponding to the sum Frame height and 1.5 cm to 2.5 cm, in particular 2 cm, away from the support plane. The insertion profiles lie directly on the webs, for example, to initiate snow loads via the webs into the substructure. To protect the web surface, however, at least one intermediate layer may be positioned between the webs and the insertion profiles. Preferably, ethylene-propylene-diene rubber or rubber or the like is used for this purpose.

The described building envelope and / or the described profiled sheet-like plate or the sandwich panel are used in particular as a roof and / or wall and / or as an inner and / or outer cladding of a building wall and / or a roof. Preferably, the building envelope described is intended to attach preferably elongate objects to building interior and / or building outer shells. In this case, the elongated objects are preferably mounted parallel to the plate plane or support plane and perpendicular to the first, that is to say perpendicular to the longitudinal direction of the webs.

Preferably insertion profiles for solar modules and / or snow catch elements are attached to building outer shells. Furthermore, an attachment of, for example, solar thermal collectors, antennas, glazings, flower boxes and / or roller shutter boxes and / or gutters and / or downpipes and / or trellises on building outer shells is possible. In the interior of the building, the building envelope with the fastening element makes it possible, for example, to mount ventilation hoods, shelves, forehear rails, interior roller blinds, glazings or else for guide rails of cable pulls or gripper arms.

FIG. 1 shows the cross section of a sandwich panel 1 perpendicular to the first direction and to the plane of the plate 2 of a profile-like plate 3, which is contained in the sandwich panel 1. The sandwich panel 1 has a lower outer layer 4, which is designed as a planar sheet metal or planar plastic layer, an upper outer layer, which is formed as profiled sheet-like plate, and arranged between lower outer layer 4 and profiled sheet-like plate 3 arranged Intermediate layer 5 on. The profiled plate-like plate 3 has a plate plane 2, from which four webs 6, which has a trapezoidal cross-section have projected in a second direction perpendicular to the plane of the plate. The webs 6 have a predetermined web height 7, which is identical for all four webs 6. Between the webs 6 protrude from the plate plane 2 in a direction opposite to the second direction direction protuberances 8, which have a dovetail-shaped cross-section. Accordingly, the opening between the two undercuts 9 of the protuberance 8 in the region of the plate plane 2 is less than the distance between the left and right side wall of the groove or protuberance 8 in a plane parallel to the plate plane 2 in the area between plate plane 2 and one by the maximum of The sandwich panel 1 is constructed so that the right foot 10 of the right land 6A is adjoined by a boundary wall 11 in a direction opposite to the second direction, which terminates at the right edge of the lower outer layer 4. Thus, the right foot 10 of the right leg 6A, the intermediate layer 5 and the lower outer layer 4 in the right area of the sandwich panel are flush and are bounded by the boundary wall 11. In the left area of the sandwich panel 1, on the other hand, adjoining the right foot 10 of the left web 6B is a boundary wall 12, which is oriented in a direction opposite to the second direction. This terminates at the left edge of the lower outer layer 4. The left web 6B of the profiled sheet-like plate 3 thus protrudes beyond the intermediate layer 5 and the lower outer layer 4. When linking a plurality of profiled sheet-like plates 1, the projection of the left web 6B of the seal is used. This web 6B projects beyond the right web 6A of a further sandwich panel and engages with it in a form-fitting manner. FIG. 2 again shows a cross section through a sandwich panel 1 perpendicular to the first direction and perpendicular to the plane of the plate 2 of a profiled sheet-like plate 3, which is contained in the sandwich panel 1. The sandwich panel 1 again contains an upper outer layer, which is the profiled plate-like plate 3, a lower outer layer 4 and an intermediate layer 5. The profiled plate-like plate 3, as in the example shown in Figure 1, four webs. 6 with a trapezoidal cross section and a web height 7. From the plate plane 2 projects in each case between two webs 6 in the direction of the second direction webs 13, which have a dovetail-shaped cross-section. Due to the dovetail-shaped webs 13, two undercuts 14 are arranged between the plate plane 2 and a plane which is formed by the regions of the webs 13 which are at a maximum distance from the plate plane 2. As in the example shown in Figure 1, the right foot 10 of the right leg 6A terminates flush with the intermediate layer 5 and the lower outer layer 4, with the right leg 10 of the right leg 6A overlapping the right edge of the lower outer layer 4 a boundary wall 11 are connected. In the left region of the sandwich panel 1, the intermediate layer 5 and the lower outer layer 4 are flush with the right foot 10 of the left web 6B, the right foot 10 of the left web 6B and the left edge of the lower outer layer 4 via a boundary wall 12th are connected. The left bridge 6B is over again.

Figure 3 shows again a sandwich panel 1, which is only by the cross-sectional shape of the Webs trained protuberances 13 different. Figure 3 shows webs 13 which are T-shaped. The T-shaped cross-section has a first leg parallel to the second direction and a second leg parallel to the plate plane 2. In the area between the second leg and plate plane 2, the webs 13 have undercuts 14.

FIG. 4 again shows a sandwich panel, which differs from the sandwich panel 1 shown in FIG. 2 only by the cross section of the protuberance 13 formed as webs. In FIG. 4, the cross-section of the webs 13 has the shape of a drop or the shape of a circle which rests on a pin arranged parallel to the second direction. In a region of the webs 13 adjacent to the plate plane 2, a constriction of the web cross-section is formed, through which undercuts 14 are again formed.

FIG. 5 shows a sandwich panel 1, which differs from the sandwich panel shown in FIG. 2 only by the shape of the protuberance 13 designed as a web. The cross section of the webs 13 in FIG. 5 is pin-shaped. The pin-shaped webs 13 protrude perpendicularly from the plane of the plate in the direction of the second direction. In such a configuration of the cross section of the webs 13 no undercuts are formed by the webs 13.

FIG. 6A shows the section through a fastening element 20 perpendicular to the first direction. The fastener 20 shown is intended to attach an object to a sandwich panel 1 as shown in FIG. Therefore, the fixing element 20 in the lower part of a gripping element, which is constructed of a sliding block 21 in trapezoidal shape and a threaded bolt 22. The threaded bolt 22 is screwed at its lower end in the sliding block 21 and has at its upper end a thread. In the upper region of the fastening element 20 is a holding element which is formed from a sliding block 23 with a rectangular cross-section and a bolt 24. The bolt 24 is screwed with its upper end in the sliding block 23 and has at its lower end undercuts 25 fertilization. Finally, a union nut 26 ensures that retaining element and gripping element can be screwed together. For this purpose, the union nut 26 is slipped over the undercuts 25 of the bolt 24. Subsequently, the threaded bolt 22 is screwed into the union nut 26. By screwing the threaded bolt 22 with the union nut 26, the fastener 20 is tensioned and thus ensures a secure hold of an object.

FIG. 6B essentially shows a fastening element comparable to the fastening element shown in FIG. 6A. The fastening element 20 again has a trapezoidal sliding block 21 and a threaded bolt 22, which constitutes the gripping element. The holding element in the upper region of the fastening element 20 is in this case constructed by a sliding block 23 with a rectangular cross-section and a threaded bolt 27, which has a thread on both sides thereof. By means of a right-left thread nut 28, the threaded bolt 22 and the threaded bolt 27 and thus the holding element and the gripping element can be screwed together. With the aid of such a fastening element 20 In turn, for example, objects are fastened to a sandwich panel, as shown in FIG.

FIG. 7 shows the section of a building envelope which has a sandwich panel IA and a sandwich panel IB. An elongate object 30 is fastened to this building envelope by means of fastening elements 20. At the transition between sandwich panel IA and sandwich panel IB, the left web 6B of the right sandwich panel IA overlaps the right web 6B of the left sandwich panel IB. Thus, the tightness of the building envelope is guaranteed.

FIG. 8 shows a section of the building envelope shown in FIG. 7 with a fastened object 30. FIG. 8 shows a sandwich panel 1, as already shown in FIG. The section of the sandwich panel 1 shown in FIG. 8 shows two webs 6 whose cross-section is trapezoidal. Between these two webs 6 protrudes from the plate plane 2 in a direction opposite to the second direction, a protuberance 8. This protuberance 8 has the shape of a groove with a dovetail-shaped cross-section. Above the supporting plane, which is given by the areas of the webs 6 which are at a maximum distance from the plane of the plate 2 and runs parallel to the plane of the plate 2, there is an elongate object 30. This object 30 is attached to the sandwich panel 1 by means of a fastening element 20. The fastening element 20 has in its lower region a gripping element, which is constructed from a trapezoidal sliding block 21 and a threaded bolt 22. The sliding block 21 is inserted or screwed into the protuberance 13 designed as a groove. The fastener 20 has further via a holding element, which is designed as a threaded bolt 27.

The gripping element and the retaining element of the fastening element 20 are screwed by means of a right-left threaded nut 28, so that a secure hold is ensured.

FIG. 9 shows a side view of a sandwich panel 1 on which a solar module 40 is fastened with the aid of insertion profiles 30, viewed from a direction perpendicular to the first direction and parallel to the plane 2. The insertion profiles 30 are formed by means of a fastening element, as shown in FIG 6A and 6B is attached to the sandwich panel 1. The insert profile itself has a cross-section, as shown in FIG. The insert profile initially has a groove in its lower region, which has a width of 60 mm and a height of 6 mm. In this can be a sliding block 23 with rectangular cross section introduce or screw. In its upper region, the insertion profile has a section 33 for introducing a solar module and a section 34 for clamping a solar module. Such insert profiles 30 are already known from the prior art. The insertion of the solar module 40 in the attached to the sandwich panel 1 insertion profiles, as shown in Figure 11, according to the prior art. For this purpose, first insertion profiles 30 are attached to the sandwich panel 1 and the building envelope at a predetermined distance. The solar module 40 is then inserted into the section 33 of a first insertion profile 3OA and subsequently embedded in the section 34 of a second insertion profile 3OB. In Figure 9 is further shown that between the two Insertion profiles 3OA and 3OB sunken solar module 40 by means of a support pad 50 is stabilized. This support block 50 is centered between the support plane, which is given by the maximum of the plate plane 2 remote areas of the webs, and the bottom 41 of the solar module 40. The supporting blocks 50 or support profiles described serve a better introduction of force of compressive forces into the substructure.

A particular advantage of the profiled sheet-like plate according to the invention or the sandwich panel according to the invention or the building envelope according to the invention lies in the fact that the roof covering and / or the side cover can be separated from the profile assembly and the solar module assembly. A solar module can therefore be retrofitted and dismantled without leaving any residue.

With the help of protruding into the second direction of a plate plane webs whose maximum distance from the plate plane areas form a support plane, offer the object to be fastened a number of load application points, which make it possible to take higher compressive forces, for example, from snow loads on the webs and in the Substructure to initiate. In addition, the defined by the height of the webs distance of the fastener between the protuberances and the object to be fastened at loads parallel to the plane leads to a self-locking and thus ensures the slipping of, for example, attached to a roof objects. Furthermore, the webs cause a back ventilation of the modules is provided.
