Abstract

The invention relates to a weather protection element (10, 30, 40, 50, 60) made of a flat material, wherein the weather protection element (10, 30, 40, 50, 60) has a plurality of raised beads and the weather protection element (10, 30, 40, 50, 60) has at least two raised beads of different heights, wherein the low raised bead (14) is provided and suitable for fastening to a supporting structure (102).

Description

[0001] The invention relates to a weather protection element made of a flat material, wherein the weather protection element has several raised beads.

[0002] Such weather protection elements are known, for example, under the name "trapezoidal sheeting." They are used, for example, as roof panels. They are attached to a substructure by screws screwing through the raised ribs into a supporting structure. The screws are screwed through the raised ribs because no water collects on the raised ribs, allowing the weather protection element to be attached to the supporting structure in a fluid-tight manner. If screws were used through the deep ribs between the raised ribs, water could collect in the deep ribs, which could then penetrate the supporting structure in the area of ​​the screws.

[0003] The problem with fastening using raised beads is that no other elements can be attached to the weather protection elements, such as photovoltaic panels, because the screw heads that protrude beyond the raised beads impair this.

[0004] The object of the present invention is therefore to provide a weather protection element to which further components can be attached.

[0005] This object is achieved according to the invention by a weather protection element made of a flat material, wherein the weather protection element has a plurality of raised beads, wherein the weather protection element has at least two raised beads of different heights and the lower raised bead is provided and suitable for attachment to a supporting structure. If raised beads of different heights are provided, the weather protection element can be attached via the lower raised beads. The lower raised beads are preferably high enough that they are not completely covered by water during normal rainfall. This enables a tight attachment. On the other hand, it is not necessary to screw through the higher raised beads. Additional elements, such as photovoltaic elements, can therefore be attached to these higher raised beads. These can, for example, be glued to the higher raised beads.

[0006] It is particularly advantageous if the height of the lower raised bead is at least 5%, preferably at least 10%, particularly preferably at least 20% of the height of the higher raised bead. This ensures that the lower raised bead is high enough for a watertight fastening.

[0007] The weather protection element can have support points located on a single plane, in particular support points, support lines, and / or support surfaces. The raised beads thus extend upwards from this plane. These support points ensure that the weather protection element can be adequately supported by a supporting structure.

[0008] The height of one or more low raised ridges can be at least 5 mm, preferably at least 30 mm. Such heights ensure that the low raised ridges are not completely submerged during normal rainfall, thus ensuring a tight attachment of the weather protection element.

[0009] Further advantages arise when the higher raised bead is at least 5 mm higher than the lower raised bead. The height difference between the lower raised bead and the higher raised bead is sufficiently large that a screw, and possibly a cap, used to secure the lower raised bead remains below the level of the higher raised bead. This means that the attachment of other components, such as photovoltaic modules, to the higher raised bead is not compromised by the attachment to the lower raised bead.

[0010] Particularly preferably, at least two high raised beads are provided. If two high raised beads are provided, two support points are formed on which another component, such as a photovoltaic module, can be placed and secured.

[0011] Furthermore, at least two low raised beads can be provided. This allows for reliable attachment of the weather protection element to a supporting structure.

[0012] In one embodiment of the invention, at least one low raised bead can be arranged between two higher raised beads. Several low raised beads can also be arranged between two higher raised beads.

[0013] It is also conceivable that several high beads are arranged next to each other.

[0014] At least one higher raised bead can be arranged between two lower raised beads. The lower raised beads can be used for attachment to a supporting structure, and the higher raised beads can be used for attachment of additional components.

[0015] According to one embodiment of the invention, high and low raised beads can be arranged alternately.

[0016] According to a further variant of the invention, more high raised beads than low raised beads can be provided.

[0017] Furthermore, it can be provided that all high raised ribs have the same height. Furthermore, all low raised ribs can have the same height. Thus, the weather protection element can have two types of raised ribs: high raised ribs that all have the same height and low raised ribs that also all have the same height. In principle, however, it would be conceivable to provide more than two raised ribs of different heights. The highest raised ribs would serve as support for additional components, such as photovoltaic modules.

[0018] Advantages arise when one or more raised beads are flat at the top. They are thus provided with a support surface, allowing additional components to be placed flatly on the raised beads.

[0019] Particularly good stability of the raised beads and the weather protection element as a whole is achieved when the raised beads are trapezoidal in shape.

[0020] In an alternative design, the weather protection element can have a wave-shaped cross-section. The raised beads are thus rounded.

[0021] The weather protection element can be made of metal, especially aluminum or steel, or of plastic, especially fiber-reinforced plastic. Weather protection elements are particularly easy to manufacture from these materials. They are also relatively lightweight. At the same time, they offer good watertightness and weather resistance.

[0022] The flat material from which the weather protection element is formed can have a thickness in the range of 0.3 mm to 2 mm, preferably in the range of 0.6 mm to 1.0 mm. Such material thicknesses achieve a good compromise between stability and low weight.

[0023] The scope of the invention also includes a roof construction with a supporting structure and at least one weather protection element according to the invention, wherein the weather protection element is fastened to the supporting structure by at least one screw and the screw is screwed through a low raised bead.

[0024] According to a further development, the roof construction can have a further component, in particular a photovoltaic module, which is fastened to the high ridges of the weather protection element, in particular glued to them.

[0025] Further features and advantages of the invention will become apparent from the following detailed description of exemplary embodiments of the invention with reference to the figures of the drawing, which illustrate details essential to the invention, as well as from the claims. The features shown therein are not necessarily to scale and are presented in such a way that the special features of the invention can be clearly seen. The various features can be implemented individually or in combinations in variants of the invention.

[0026] The schematic drawing shows embodiments of the invention and explains them in more detail in the following description.

[0027] They show: Fig. 1 a weather protection element with alternating high and low raised beads, which are trapezoidal in shape; Fig. 2 a weather protection element with high and low raised beads, with at least two raised beads of the same height arranged next to each other; Fig. 3 a weather protection element with more high than low raised beads; Fig. 4 a weather protection element similar to that of Fig. 1 with a larger height difference between high and low ridges; Fig. 5: a wave-shaped weather protection element in section; Fig. 6: a roof construction.

[0028] Fig. 1 shows a perspective schematic representation of a weather protection element 10. The weather protection element 10 has higher raised beads 12 and, in comparison, lower raised beads 14. Furthermore, the weather protection element 10 has support points 16 designed as support surfaces, which are arranged between two raised beads 12, 14. The support points 16 lie on a plane 20. The raised beads 12, 14 extend upwards from this plane 20. The lower raised beads 14 are intended to be fastened to a supporting structure. For this purpose, one or more screws can be screwed from above through the lower raised beads 14. In the exemplary embodiment shown, the higher raised beads 12 have a plane 18 at the top. They thus have a support surface to which further components, such as a PV module, can be fastened. In particular, such a module can be glued to the higher raised beads 12.

[0029] Furthermore, it can be seen that the weather protection element 10 is made of a flat material. In particular, the material from which the weather protection element 10 is made is significantly flatter, ie, it has a lower material thickness than the height of the raised beads 12, 14. The height of the higher raised bead 12, in particular the height relative to the plane 20, is designated H1 and the height of the lower raised bead 14 is designated H2. In the embodiment of the Fig. 1 High and low raised beads 12, 14 are arranged alternately. Both types of raised beads 12, 14 are trapezoidal in shape.

[0030] The height H2 is dimensioned such that, during normal rainfall, the lower raised bead 14 is not completely covered by water. In the illustrated embodiment, the height H2 is approximately 80% of the height H1. The difference between the heights H1 and H2 is preferably such that this difference is greater than the height of a cap and a screw head used to attach the weather protection element 10 to the lower raised bead 14.

[0031] The weather protection element 30 of the Fig. 2 Two low raised beads 14 are always arranged between higher raised beads 12. Furthermore, three higher raised beads 12 are always arranged between two lower raised beads 14. In particular, groups of three higher raised beads 12 and two lower raised beads 14 alternate. In the illustrated embodiment, the height of the low raised bead 14 is approximately half the height of the higher raised bead 12.

[0032] When designing a weather protection element 40 according to the Fig. 3 A low raised bead 14 is arranged between two higher raised bead 12. There are more higher raised bead 12 than low raised bead 14. Groups of three higher raised bead 12 and one low raised bead 14 alternate. The higher raised bead 12 is narrower at the top than the low raised bead 14.

[0033] The Fig. 4 shows a weather protection element 50 which is similar to that of the Fig. 1 Here, too, higher and lower raised beads 12, 14 alternate. However, the height difference between the high and low raised beads 12, 14 is greater than in the design according to the Fig. 1 .

[0034] The Fig. 5 shows another weather protection element 60, which has a wave-shaped cross-section. The higher and lower raised beads 12, 14 are therefore rounded at their upper ends. The support points 16 are also rounded. Here, too, higher and lower raised beads 12, 14 alternate.

[0035] The Fig. 6 shows a roof construction 100 with a supporting structure 102, on which a weather protection element 50 is placed. The weather protection element 50 is attached to the supporting structure 102 by means of the lower raised beads 14. This is indicated by the screws 104. Here, it can be seen that the screw head 106 of the screw 104 is arranged below the upper side of the higher raised bead 12. This leaves a gap to a PV module 108, which is placed on the higher raised beads 12 and attached to them by adhesive.
