Device for fastening plate-shaped components, in particular solar modules and solar collectors 5

The invention relates to a device for fastening plate-shaped components, in particular solar modules and solar collectors, preferably on sloping surfaces, in particular on pitched roofs, whereby the plate-shaped components are arranged on them in the longitudinal direction, lying one above the other in a scale-like manner, and the component lying on top in the direction of the higher side overlaps with its front end the rear end of the component lying underneath and the plate-shaped components on the profiles which are fastened in the longitudinal direction to essentially horizontally lying framework parts, such as roof battens, and are hooked into hooks with their lower end, whereby each profile has on its upper side two lateral support surfaces extending in its longitudinal direction and a recess lying between these support surfaces, and the components rest with their lateral edges on one of the support surfaces of the profile and a gap remaining free between them is arranged above the recess, whereby each profile has on its upper side two lateral support surfaces extending in its longitudinal direction and a recess between these support surfaces and the components rest with their lateral edges on one of the support surfaces of the profile and a gap remaining free between them is arranged above the recess, wherein the profile has a U-profile part that is open at the bottom, wherein an upwardly open angle is connected to the two vertical legs at their free ends, the horizontal leg of which forms the lower leg of the profile and the vertical outer leg of which laterally delimits the profile, wherein a horizontal shoulder is arranged in the outer leg of the upwardly open angle, which divides the leg into an upper section and a lower section, wherein the lower section of a second profile can be inserted into the upper section of a profile and both sections lie against one another in a form-fitting manner, wherein the plate-shaped component projects forwards beyond the profile with its front end.

DE1199RÖ01

Such a device is already known from EP 0 761 A1. In this device, holes for horizontally receiving a retaining bolt are arranged in the upper section of the profile at a predetermined location in the legs of the U-profile part and the outer legs of the angle, with the hook for holding the plate-shaped components being pivotably mounted on the retaining bolt.

Such a device is well suited to arranging plate-shaped components, preferably on sloping surfaces, especially on pitched roofs. When using such profiles, simple assembly is possible, especially of solar modules and solar collectors. However, when using the device, it has become apparent that the pivoting arrangement of the hooks when holding the plate-shaped components is not an optimal solution. When hanging the plate-shaped components, the hooks must be brought into the receiving direction for the components so that they can be hung. This is particularly difficult with large plate-shaped components. In addition, the arrangement of a retaining bolt in holes in the legs and outer legs of the profile requires additional manufacturing effort.

The invention is based on the object of creating a device for fastening plate-shaped components, in particular solar modules and solar collectors, in accordance with the preamble of claim 1, in which the hanging of the plate-shaped components in hooks is simplified and at the same time a secure suspension is ensured.

According to the invention, the object is achieved in that the plate-shaped component is fixed in its position by the hooks and the plate-shaped component rests on a web of the hook and the front end of the web is U-shaped and forms the actual receptacle of the plate-shaped component, with one leg extending vertically upwards from the web and a second leg extending downwards from the leg.

is bent at the back in the direction of the web and parallel to it and in the area of the rear end of the hook a leg that is almost at a right angle to the web is bent downwards and on the leg another leg is bent at a right angle to the back, so that the rear end of the hook is Z-shaped and in the rear, horizontal leg there is a hole for receiving a fastening element and that the hook is fastened to the lower leg of the profile via the fastening element.

The inventive design of the suspension with the hooks enables the plate-shaped components to be attached easily and safely to the installation location. The hooks are firmly connected to the profile so that the components can be pushed along the profile and the web of the hook into the front U-shaped part of the hook.

It is advantageous that at the front end of the hook with the U-shaped end of the web, the clear width between the leg arranged parallel to the web and the web corresponds at least to the thickness of the plate-shaped component.

A rubber-like material can be arranged between the surface of the plate-shaped component and the inside of the front end of the hook, whereby damage to the plate-shaped component can be largely prevented.

To ensure a good connection between the plate-shaped components and the profile, it is advisable that the length of the leg bent downwards from the web corresponds at least to the clear height of the profile.

A preferred embodiment consists in that when forming the plate-shaped component as a solar module

DE1199RÖ01

dul or as a solar collector between the support surface of the plate-shaped component on the profile and the underside of the component, a glass support made of a rubber-like material is arranged.

With the solution according to the invention, it is possible that the position of the plate-shaped component and the scale-like overlap of the plate-shaped components are determined by the point of attachment of the hook to the lower leg of the profile and the distance between the center axis of the hole in the rear, horizontal leg of the hook and the inside of the vertical leg of the U-shaped front end of the hook.

The invention is explained in more detail using an embodiment. The accompanying drawing shows:

In Fig. 1, a device is shown with which plate-shaped components 1 are arranged as solar modules in the longitudinal direction on a sloping roof, lying one above the other in a scale-like manner. The solar module, which is located at the top in the direction of the roof ridge, overlaps the rear module with its front end.

End of the underlying solar module. The solar modules are located on profiles 2 that also extend in the longitudinal direction of the roof. The profiles 2 are attached to horizontally running framework parts 3 in the form of roof battens with fastening elements 4. A hook 5 is arranged at the front end of the profile 2. The plate-shaped component 1 is inserted into the hook 5 with its front end.

The device can be used to attach frameless and framed solar modules. However, other plate-shaped components 1, such as solar collectors or cladding elements, can also be attached. The device can also be used to attach plate-shaped components 1 to vertical walls.

Fig. 2 shows the suspension of the plate-shaped component 1 designed as a solar module. The solar module protrudes forwards beyond the profile 2 with its front end, which means that it can lie above the rear end of the solar module below it, as shown in Fig. 1. The solar module is fixed in position by the hook 5. The hook 5 is shown in more detail in Fig. 5. The solar module rests on a web 23 of the hook 5. The front end of the web 23 is U-shaped and forms the actual holder for the solar module or the plate-shaped component 1. Here, one leg 21 of the web 23 is bent vertically upwards and a second leg 22 of the leg 21 is bent backwards parallel and in the direction of the web 23. The clear width between the web 23 and the leg 22 corresponds to at least the thickness of the plate-shaped component 1. To avoid structural damage to the solar module, an insert 20 made of a rubber-like material, such as EPDM or neoprene, can be arranged between the surface of the solar module and the inside of the U-shaped lower end of the hook 5.

In the area of the rear end of the hook 5, a leg 24 is bent downwards from the web 23 at approximately a right angle.

gen. On the leg 24, a further leg 25 is bent backwards at a right angle, so that the rear end of the hook 5 is Z-shaped. A hole 26 for receiving the fastening element 6, preferably a screw, is provided in the horizontal leg 25. The hook 5 (Fig. 2) is fastened to the lower leg 16 of the profile 2, on which the plate-shaped component 1 rests, by means of the fastening element 6.

The length of the leg 24 bent downwards from the web 23 corresponds at least to the clear height of the profile 2, wherein a glass support 7 made of a rubber-like material, preferably EPDM or neoprene, is preferably arranged between the support of the solar module on the profile 2 and the underside of the solar module.

The position of the plate-shaped component 1 and the scale-like overlap of the plate-shaped components 1 and the solar modules in the longitudinal direction shown in Fig. 1 are essentially determined by the point at which the hook 5 is attached to the lower leg 16 of the profile 2 and the distance between the center axis of the hole 26 in the leg 25 at the rear end of the hook 5 and the inside of the vertical leg 21 of the U-shaped front end of the hook 5.

In Fig. 3, a profile 2 is shown in the installed state corresponding to the section A-A in Fig. 1. The profile 2 consists of metal, preferably aluminum or an aluminum alloy. It has a central, downwardly open U-profile part 8, to the two front legs 12 of which an upwardly open right angle 15 with its horizontal legs 16 is connected at their free ends, with its vertical outer leg 17 laterally delimiting the profile 2. The horizontal web 9 of the U-profile part 8 forms the middle area of the profile 2. On the top of the web 9, at a predetermined lateral distance from one another, two profile elements 10 with a horizontal surface are arranged.

DE1199RÖ01

support surface 10a and a gap 10b for receiving the glass support 7. The glass support 7 consists, as described above, of a rubber-like material and has a horizontal flat surface 7a and a vertical web 7b. The vertical web 7b of the glass support 7 is inserted in the gap 10b of the profile element 10, so that the glass support 7 is positively connected to the profile element 10. The flat surface 7a rests on the support surface 10a of the profile element 10. The plate-shaped component 1, in the present case the solar module, rests on the free side of the flat surface 7a of the glass support 7. Between the profile elements 10, vertical webs 27 are arranged, which form a recess serving as a water drain 28 and limit it laterally. The vertical legs 12 extend without a step from the horizontal web 9 of the U-profile part 8 downwards to the horizontal leg 16 of the angle 15.

A horizontal step 13 is arranged in the vertical outer leg 17 of the angle 15, which divides the leg 17 into an upper section 28 and a lower section 29 with an approximately equal internal clear height. On the vertical outer leg 17 of the angle 15, a sliding piece 18 of the same width is arranged at the upper end on the inside and at the lower end on the outside, the height of which corresponds approximately to half the internal clear height of the sections 28; 29. The clear width of the upper section 28 is greater on the side of the vertical outer leg 17 of the angle 15 by the material thickness of the profile 2 and the width of the sliding piece 18 than the clear width of the lower section 29. This allows the profiles 2 to be pushed into one another in the longitudinal direction.

Openings 16a for receiving fastening elements 4 are provided in the horizontal leg 16 of the angle 15.

With the fastening elements 4, in the example wood screws, the profiles 2 are fastened at their upper ends to the scaffolding parts 3, i.e. to the roof battens (Fig. 4).

The lower end of the upper profile 2 is, as shown in more detail in Fig. 4, inserted into the upper end of the underlying profile 2 or is also attached to a scaffolding part 3 at the lower end of the device.

The fastening element 4 can be designed differently depending on the design of the scaffolding part 3.

As shown in Fig. 3, the horizontally arranged plate-shaped components 1 are placed on the profiles 2 with their lateral edges on a support surface 10a of the profile element 10 or the flat surface 7a of the glass support 7, with a gap 14 between them above the water drain 11, which prevents them from colliding with one another. Penetrating moisture, such as rainwater, flows downwards via the water drain 11.

Fig. 4 shows how the profiles 2 are mounted to achieve the scale-like arrangement. The rear end of the lower profile 2 is fastened to the scaffolding part 3 with the fastening element 4, in this example a wood screw. The front end of the upper profile 2 is pushed with its lower lateral section 29 into the upper lateral section 28 of the lower profile 2.

The structural design of the profile 2 described above ensures a positive connection between both profiles. The horizontal surfaces of the sliding pieces 18 arranged on the vertical outer legs 17 rest against one another and thus prevent loosening by lifting the upper profile 2.

The profiles 2 can be pushed into each other to any length, which allows differences in length to be compensated.
