Abstract

Description

Background of the invention

[0001] The invention relates to a building protection element and a solar module arrangement.

[0002] It is known to mount solar modules on a structure, particularly on a flat roof or balcony, using a support frame or support element. With this arrangement, care must be taken to ensure that the structure on or against which the solar module is mounted is not damaged by the support frame and / or a fastening device for the support frame.

[0003] For this purpose, structural protection mats are typically used. These are placed between the support frame and the building and prevent damage to the building, in particular penetration of the building's waterproofing. To ensure that the support frame does not leave the structural protection mat during installation, for example, due to alignment or displacement, the structural protection mats are laid out over a large area or have considerable dimensions. However, this increases the material required for a solar module arrangement to be installed, as well as the effort required for providing, in particular transporting, the structural protection mats to the installation site and subsequently laying them out. In all cases, the installation costs for a corresponding solar module arrangement are significantly increased.

[0004] Furthermore, placing the support frame on the building protection mat inherently raises the surface above the installation area. This makes it difficult to arrange known mounting weights on the support frame, which are intended to prevent weather-related shifting of the solar module array after installation. The resulting elevation is typically compensated for with bulk material, such as gravel or earth, to create a level support surface for the mounting weights. However, this further increases the installation time and may require additional effort to provide the bulk material. Object of the invention

[0005] It is an object of the invention to provide a building protection element to enable the installation of a solar module arrangement in a cost-effective and damage-free manner and at the same time to ensure security against displacement of the solar module arrangement. Description of the invention

[0006] This object is achieved according to the invention by a building protection element with at least one first groove-like recess for receiving a support element section of a support element carrying a solar module, as well as with load-bearing surfaces for supporting assembly weights.

[0007] The building protection element according to the invention is preferably arranged between a supporting element section and the building, for example a flat roof, a balcony or a terrace. Thus, the supporting element has no direct contact with the building. This measure alone can prevent damage to the building. The fact that a groove-like recess is provided on the building protection element predetermines the relative position of the building protection element and the supporting element section. Relative movement of the building protection element and the supporting element is prevented in at least one direction, thereby effectively preventing displacement of the supporting element beyond the edge of the building protection element. Furthermore, the supporting element can be moved together with the building protection element, thereby enabling easy repositioning of the supporting element.The fact that the building protection element also has load-bearing surfaces to support installation weights also prevents the load-bearing element from causing local elevation. This means that additional compensation for the height difference is no longer necessary. In addition, the load-bearing surfaces prevent an installation weight from coming into direct contact with the structure. This means that even with small building protection elements, damage to the structure caused by installation weights can be prevented. In particular, the load-bearing element section can be clamped between the building protection element and one or more installation weights. The depth of the groove-like recess, i.e. the distance from a load-bearing surface to a groove base, can roughly correspond to the height of the load-bearing element section.

[0008] The building protection element can have a rectangular basic shape, in particular an I-shape. The rectangular basic shape can be square. However, advantages arise if the rectangular basic shape has an I-shape, i.e., has a shorter and a longer side. This allows a building protection element to be realized with little material expenditure and simple geometries, thereby reducing manufacturing costs. The building protection element can be designed symmetrically with respect to a longitudinal axis. It can also be designed symmetrically with respect to a transverse axis. This reduces the outlay for preparing the building protection elements. A compact basic shape facilitates transport.

[0009] In a special embodiment, the width of the rectangular structural protection element is half the length of the rectangular structural protection element. This allows two similar structural protection elements to be arranged with their longer sides adjacent to each other. This ensures, on the one hand, a predetermined installation distance between two support element sections, and, on the other hand, a single square weight can be used to weigh down both structural protection elements and the support element sections arranged on them.

[0010] According to an advantageous embodiment, the structural protection element can have at least one second groove-like recess for receiving a supporting element section. Thus, multiple supporting element sections can be supported by the structural protection element.

[0011] The groove-like recesses can be aligned parallel to each other, whereby a predetermined distance between two support frame elements can be ensured.

[0012] Preferably, the first and second groove-like recesses are aligned perpendicular to each other. It is particularly advantageous if the first and second recesses intersect. This allows the structural protection element to accommodate beam intersections, or a special longitudinal or transverse arrangement of supporting elements can be realized. This ensures flexible use of the structural protection elements in predetermined installation spaces.

[0013] The structural protection element can have at least one lateral stop for a mounting weight. This allows the relative position of the mounting weight and the structural protection element to be determined, ensuring consistently reliable installation. Furthermore, slipping of the mounting weight can be prevented.

[0014] It is often necessary to readjust the alignment of the solar module. This may be difficult or even impossible if all the required mounting weights are installed. However, if no mounting weight is installed during the adjustment, there is a risk that the solar module will move if a mounting weight is installed after the adjustment and the precise adjustment will be lost. With the building protection element according to the invention, it is possible, for example, to arrange just one mounting weight on the building protection element and to fix its position relative to the building protection element and support element so that the solar module still remains movable. During alignment, the lateral stop prevents the mounting weight from slipping relative to the building protection element. Opposing stops are preferably provided so that the mounting weight rests against a lateral stop on opposite sides.Particular advantages arise when at least four lateral stops are provided. This allows the position of the mounting weight to be determined and maintained particularly well. In particular, stops can be provided in a number and arrangement such that the mounting weight rests against at least one stop on all sides.

[0015] The underside of the structural protection element can be laminated, particularly with aluminum. This prevents plasticizers from escaping, particularly from migrating into a film of the structure and negatively affecting the sealing properties.

[0016] The structural protection element is preferably designed with multiple levels in the vertical direction. This allows for the creation of surfaces at different heights for different functions. In particular, a surface can be created on which a supporting element section rests. Another surface can be created on which an installation weight can rest. At a further height, a surface can be created that closes off the structural protection element at the top. In particular, the highest surface can represent the top of a lateral stop.

[0017] The underside of the structural protection element can have recesses corresponding to the lateral stops. In particular, the underside of the structural protection element can be designed, at least partially, as a negative of the upper side. This allows the structural protection elements to be easily stacked on top of one another. This can be advantageous if a roof was not constructed precisely due to structural reasons, i.e., has certain unevenness, or if the flat roof already has different heights due to planning. Stacking the elements on top of one another compensates for these unevenness, and the stacked structural protection elements cannot slip against one another.

[0018] Particular advantages arise when the structural protection element is made of a flexible and / or elastic material. Such a material can adapt, at least to a limited extent, to a substrate, such as the gravel on a flat roof. The material can interlock, particularly with a substrate that is not completely smooth, thus ensuring a reliable installation. Even minor weather-related relative movements between the substrate and the supporting element can be compensated for.

[0019] The first and / or second recesses can extend parallel to a side edge of the structural protection element. In particular, the recesses can be substantially rectilinear. They can each be provided centrally on the structural protection element.

[0020] The building protection element can be implemented particularly cost-effectively if it is made of rubber, especially rubber granulate. This material also exhibits elastic properties.

[0021] The building protection element can have a height in the range of 15 to 25 mm, preferably 20 mm, in the region of the first and / or second recess. In the region of the load-bearing surfaces, it can have a height in the range of 25-35 mm, preferably 29 to 31 mm, in particular 30.5 mm. The recesses can have a depth, i.e., distance from the load-bearing surface to the groove base, in the range of 5 to 15 mm, preferably approximately 10 mm, in particular 10.5 mm. The stops can protrude 5 to 15 mm, preferably 10 mm, above the load-bearing surfaces.

[0022] The recesses can each have a width in the range of 50 to 90 mm, in particular in the range of 60 to 80 mm, preferably 70 mm. The width of the recess is preferably adapted to the width of the support element section to be accommodated and / or to the width of two support element sections to be accommodated side by side in a recess. In other words, the width of the recess can accommodate one or two support element sections. Particularly preferably, the width of the recess is slightly narrower than the width of the support element section, so that the support element section can be clamped in the recess.

[0023] Alternatively or additionally, it can be provided that the groove-like recesses have two or more locking lugs which project laterally into the recesses and clamp the support element section arranged therein.

[0024] The recesses can be the same width. This means that in some cases, the orientation of the building protection element does not need to be considered during installation.

[0025] The building protection element can have a length of 300 - 500 mm, preferably 400 mm, and a width of 100 - 300 mm, preferably 200 mm.

[0026] The scope of the invention also includes a solar module arrangement comprising a solar module, a support element to which the solar module is fastened, at least one building protection element according to the invention and at least one mounting weight, wherein a support element section is arranged in a recess of the building protection element and the mounting weight is placed on the load-bearing surfaces of the building protection element in the region of the support element section.

[0027] Further advantages of the invention will become apparent from the description and the drawings. Likewise, the above-mentioned and further-described features can be used individually or in combination in any desired manner. The embodiments shown and described are not intended to be exhaustive, but rather are exemplary in nature for describing the invention. Detailed description of the invention and drawing Fig. 1 shows a perspective view of a building protection element; Fig. 2 shows a plan view of an alternative design of a building protection element; Fig. 3 shows a side view of a solar module arrangement; Fig. 4 shows a bottom view of an alternative design of the building protection element; Fig. 5 shows a side view of an alternative solar module arrangement with several building protection elements according to Fig. 4.

[0028] The Fig. 1 shows a building protection element 10 which has a rectangular basic shape, i.e., an I-shape. The building protection element 10 is stepped. This means that several surfaces of different heights are provided. A first groove-like recess 12 extends in the longitudinal direction of the building protection element 10, in particular parallel to a side edge 14. The groove-like recess 12 is arranged centrally with respect to the width of the building protection element 10. The groove-like recess 12 serves to accommodate a support element section (not shown here) of a support element which serves to hold a solar module. The groove base of the first groove-like recess 12 represents a first surface and thus a first height level.

[0029] The building protection element 10 has a second groove-like recess 16, which is aligned parallel to the side edge 18. The groove-like recesses 12, 16 are arranged perpendicular to one another. In particular, they intersect. The second groove-like recess 16 is arranged centrally with respect to the length of the building protection element 10, as shown. Alternatively or additionally, however, it can also be provided that the first and / or second groove-like recess is arranged off-center with respect to the length of the building protection element 10. The groove base of the second groove-like recess 16 is at the same height as the groove base of the first groove-like recess 12.

[0030] The structural protection element 10 further comprises load-bearing surfaces 20, 22, 24, 26. A mounting weight can be placed on the load-bearing surfaces 20-26, clamping a supporting element section between the structural protection element 10 and the mounting weight. The load-bearing surfaces 20, 22, 24, 26 represent a second height level of the structural protection element 10. The first height level typically has a height difference from the second height level, which corresponds to the height of the supporting element section to be accommodated.

[0031] Adjacent to the load-bearing surfaces 20-26 are stops 28, 30, 32, and 34. A mounting weight can be applied laterally to these stops 28-34, thus fixing its position. In particular, the stops 28-34 prevent relative movement between the structural protection element 10 and the mounting weight. The upper side of the stops 28-34 represents a further height level of the structural protection element 10. The different height levels create the stepped design of the structural protection element 10. The further height level typically has a height difference from the second height level, which corresponds to the height of the mounting weight to be supported. This allows for a level connection between the mounting weight and the stops, creating a flat surface.

[0032] Typically, the first height level, the second height level and / or the further height level are formed parallel to each other.

[0033] The first and second groove-like recesses 12, 16 have the same width in the illustrated embodiment. In particular, they can have a width of approximately 70 mm. The height of the groove-like recesses 12, 16, in particular the distance from the groove base of the groove-like recesses 12, 16 to the load-bearing surfaces 20-26, can be approximately 10 mm. Likewise, the distance between the load-bearing surfaces 20-26 and the upper side of the stops 28-34 can be approximately 10 mm. The total height, i.e. the distance from the underside 36 to the upper side of the stops 28-34, can be approximately 40 mm. The underside 36 can have a lamination, in particular an aluminum lamination.

[0034] The Fig. 2 shows a plan view of an alternative embodiment of a building protection element 100. Features that are similar to those of the building protection element 10 of Fig. 1 are marked with the same reference numerals. The main difference between the building protection element 100 and the building protection element 10 of Fig. 1 is that the structural protection element 100 is square. Furthermore, the stops 28-34 are not rectangular, but L-shaped. Thus, a square mounting weight can be supported at its corners by the stops 28-34 and thus immovably mounted on the structural protection element 100.

[0035] The Fig. 3 shows a side view of a solar module arrangement 200 arranged on a base 202, in particular a building. The solar module arrangement 200 comprises a solar module 210, for example a photovoltaic collector or a solar thermal collector, which is attached to a support element 212. The support element 212 has a horizontally oriented support element section 214, which is inserted over part of its length into the first groove-like recess 12 of two building protection elements 10. A plurality of mounting weights 216 are stacked on the building protection elements 10. It can be seen that the respective lowest mounting weight 216 is arranged between stops 28, 34 and is thus immovably arranged on the respective building protection element 10. The support element section 216 is clamped between the building protection elements 10 and the mounting weight 216 and is thus fixed.

[0036] The Fig. 4 shows a bottom view of an alternative embodiment of a building protection element 300. The building protection element 300 essentially corresponds to the building protection element 10 from Fig. 1. However, the building protection element 300 has four receptacles 36, 38, 40, 42, which are formed as recesses in the building protection element 300. The receptacles 36, 38, 40, 42 are designed to complement the stops 28, 30, 32, 34 of another building protection element 10, 100, 300. This allows the stops 28, 30, 32, 34 to be received in the receptacles 36, 38, 40, 42. This enables the building protection elements 10, 100, 300 to be stacked in a precise position and also prevents them from shifting among each other.

[0037] The Fig. 5 shows a side view of an alternative solar module arrangement 400 arranged on a base 404 having a height difference 402. The solar module arrangement 400 essentially corresponds to the solar module arrangement 200 of Fig. 2. However, according to the embodiment in Fig. 5, several building protection elements 300 are stacked to compensate for the height difference 402 and / or to arrange the support element 412 at a higher elevation. An elevated arrangement can be advantageous with respect to a possible shadow gradient. The support element 412, or the support element section 414, can be aligned horizontally accordingly, and the arrangement of the mounting weights 416 can thus be carried out in a positionally accurate manner. According to Fig.Figure 5 shows the stacked arrangement of the structural protection elements 300 on a support element section 414. It goes without saying that a height difference can be achieved by stacking the structural protection elements 300 on different support element sections 414 of the support element 412, in particular sections arranged parallel to one another.
