Description

[0001] The invention relates to a profile and a system for mounting a roof covering, in particular including a solar cell, which allows for simple and flexible mounting, especially directly on a waterproof and / or fire-resistant film, is easy to manufacture and in particular can be used modularly.

[0002] This involves using at least one profile that fulfills various functions. In more complex designs, the system is supplemented by at least one second type of component. For example, the profile can be connected to a solar cell array, and the second component can be a profile with a plastic panel. This allows for the modular combination of solar cells and plastic panels during roofing.

[0003] In further embodiments, a second profile can be attached opposite the plate or solar cell, which, for example, seals together with the first profile of an adjacent component.

[0004] Profiles and panels or solar cells can also be provided separately and designed to be plugged together. This further increases flexibility.

[0005] Generally, it is preferred that the building components are coordinated in terms of their dimensions, in particular having a uniform length and height with respect to the sections to be joined. Several system sizes can also be kept on hand to accommodate differently shaped and / or sized roof areas with adapted sizes.

[0006] The purely schematic and non-restrictive figures are described below as purely exemplary illustrations. They also show preferred designs.

[0007] The problem is solved by a profile for covering a roof with slab-shaped roofing tiles, - wherein the profile has at least one recess, in particular circular and / or hole, for screwing through with a screw, in particular wood screw and / or self-tapping screw, from a top to a bottom of the profile, - wherein the profile has a longitudinal extent and, in particular over at least 50% of the longitudinal extent, in particular between the upper and lower sides, has at least one, in particular lateral, receptacle for a, in particular plate-shaped, roof covering which extends after the receptacle in particular to one side of the profile, or is connected with such a receptacle, - wherein the profile, extending along its longitudinal extent, in particular over at least 50% of the length and / or the length of the at least one receptacle and / or the length over which the at least one receptacle is (distributed), has on its upper side extending in the direction of the longitudinal extent at least one sealing element, in particular designed as a first part and / or comb of a labyrinth and / or gap seal, - wherein the profile has a limiting element on its underside, configured to engage a plate-shaped element and thereby limit the sliding of the profile onto the plate-shaped element, formed by a spacer section projecting from the underside and an engagement section projecting from it in the direction of the longitudinal extent of the profile, - wherein the profile has a protruding support section, in particular a support nose, on its underside, which protrudes further from the underside than the limiting element, in particular the interlocking section, wherein in particular the spacer section is part of the support section, - wherein the recess extends in the direction of the longitudinal extent of the profile on the side of the spacer section and / or the support section facing away from the interlocking section.

[0008] The problem is also solved by a system of two profiles, wherein the first profile is a profile according to one of the preceding claims and the second profile is a profile for covering a roof with slab-shaped roof coverings and - wherein the second profile has a top and bottom and a longitudinal extent in the range of 10 cm less than the longitudinal extent of the first profile up to the longitudinal extent of the first profile - wherein the profile has a longitudinal extent and has at least one, in particular lateral, receptacle for a, in particular plate-shaped, roof covering over at least 50% of the longitudinal extent between the upper and lower surfaces, or is connected to such a receptacle. - wherein the profile, extending along its longitudinal extent, in particular over at least 50% of the length and / or the length of the receptacle, has on its underside extending in the direction of the longitudinal extent at least one sealing element, in particular designed as a second part and / or comb of a labyrinth and / or gap seal.

[0009] The top side is specifically the side intended to be oriented away from the building during installation. It is specifically positioned opposite the support section. "Lateral" means, in particular, perpendicular to the longitudinal extent of the profile and perpendicular to the direction from the top to the bottom.

[0010] The at least one receptacle can be designed, for example, as a receptacle for placement and three-sided or four-sided limitation and / or as a slot for insertion and / or as several recesses, in particular for the respective reception of a mushroom-shaped extension in cross-section along the longitudinal direction of the profile, in particular a second profile of a further component.

[0011] Advantageously, the receiver has at least one longitudinal groove for receiving adhesive for bonding the plate-shaped roof covering, in particular solar cell arrangement and / or plastic panel.

[0012] Advantageously, the first and / or second profile and / or the first and / or second recess is designed as a drainage system, particularly in the longitudinal direction, especially by forming a longitudinally extending groove and / or drain, particularly in the form of a notch, a slot, and / or a hole at the end of the longitudinal extension opposite the recess, particularly at the end of the longitudinal extension extending in the longitudinal direction and / or to the underside. This allows water penetrating the profile, especially into the second recess, to drain away, particularly onto plate-shaped elements arranged below.

[0013] Advantageously, the receptacle has a limiting section extending perpendicular to the longitudinal extent at the end of the longitudinal extent opposite the recess, or at the end of the longitudinal extent, and / or a second interlocking section extending away from the recess, which extends, in particular, perpendicular to the longitudinal extent beyond the receptacle and / or across the entire width of the profile. The limiting section can also extend into a second receptacle and / or across the entire width of the profile. In this way, a second receptacle for another plate-shaped element is created next to the first.

[0014] Advantageously, the recess is arranged in a mounting section projecting from the top, from which the second interlocking section extends and / or which is formed with at least one end curve, particularly with respect to the longitudinal extent of the profile. This curve allows the components, which are pushed on from above, to slide off during assembly. The screw can be countersunk into the projecting mounting section.

[0015] Advantageously, the profile has a second recess for a plate-shaped roof covering, which is directly adjacent to the first, is parallel to it and / or has the same length and / or has a limiting section extending perpendicular to the longitudinal extension towards the side of the recess or at the end of the longitudinal extension and / or has a second interlocking section extending away from the recess, which in particular extends perpendicularly to the longitudinal extension beyond the recess and / or over the entire width of the profile, wherein the limiting section and / or interlocking section are in particular parallel to the respective section of the first recess and / or formed integrally with it.

[0016] Advantageously, the support section is designed with a curve that extends over its entire height and / or on the side of the support section facing away from the interlocking section. This curve protects an underlying structure, particularly a film, and prevents tears in the film.

[0017] Advantageously, the profile has a flat, rod-shaped base body, which can be made of solid material or be partially hollow and, in particular, open at the bottom by webs, which defines the top and bottom surfaces as well as the longitudinal extent.

[0018] Advantageously, the profile has at least one, and in particular at least two, sealing devices on its underside around the recess. These devices are particularly concentric, nested within one another, and / or circular in shape. They are particularly concentric around the recess and, in particular, integral with the profile, especially as protruding ridges and / or recesses. This allows a hole created in a foil by the screw connection to be effectively resealed.

[0019] Advantageously, the mounting is such that when the profile is screwed onto a plate with its underside, the mounted plate-shaped element is secured against lifting perpendicular to the plate surface and / or the mounting is designed such that a receiving space is formed between the underside and top of the profile, limited towards the top and especially also towards the underside, and / or at least a second interlocking element is provided above the top to secure the mounted plate-shaped element against lifting.

[0020] Advantageously, the first and / or second profile and / or the plastic sheet is made of plastic, in particular plastic, polymer, polycarbonate and / or ASA (acrylonitrile styrene acrylate), in particular comprising 10 to 30 wt. % glass fiber, for example Prospector HiFill ASA GF20 or Prospector Bayblend T88 GF-20.

[0021] Advantageously, the profile is connected, in particular bonded, to a solar cell arrangement included in the recording, in particular comprising a carrier plate, solar cells arranged on it and a cover plate, wherein the support section extends to at least 5 mm, in particular at least 10 mm, behind the solar cell arrangement.

[0022] A solar cell assembly preferably comprises a plate-shaped support, solar cells, and a cover layer. It preferably does not have a metallic frame.

[0023] Advantageously, the profile is connected, particularly bonded, to a solar cell arrangement included in the mount, in particular comprising a carrier plate, solar cells arranged on it, and a cover plate, wherein the support section extends at least 5 mm, and in particular at least 10 mm, behind the solar cell arrangement. This allows a space for rear ventilation to be created behind the solar cells. In particular, the plastic plate and / or the system containing it are also designed to form an air space, in particular so that a continuous cavity is created when combining components with solar cells and those with plastic plates.

[0024] Advantageously, the profile is connected to a plastic plate held in the recess, in particular by gluing or snapping, wherein the bearing section extends at least 5 mm, in particular at least 10 mm, behind the plastic plate, wherein the plate in particular has a grid extending perpendicular to the longitudinal extent of the profile and arranged at the end of the longitudinal extent facing away from the recess. This allows ventilation of the cavity and / or improves stability against externally exerted pressure.

[0025] Advantageously, the profile features a grid extending perpendicular to its longitudinal axis and positioned at the end of the longitudinal axis furthest from the recess. This allows for ventilation of the cavity and / or improves stability against external pressure.

[0026] In one embodiment, the receptacle is designed for the, in particular lateral, insertion of a plate-shaped element and has, in particular, clamping elements extending into the receiving space, in particular designed to hold a received plate-shaped element clamped in the receiving space.

[0027] Advantageously, the profile and / or the first / or second receptacle and / or the plastic plate have expansion compensation lugs projecting perpendicular to the longitudinal extent and perpendicular to the direction from the top to the bottom, and / or the receptacle has a lateral boundary designed to allow lateral movement of the received plate-shaped element of at least 0.5 mm, in particular through elastic deformation and / or non-elastic breaking. The lugs can be designed to be pressed into the first or second profile and / or to compress themselves. Lugs that break away under pressure are also conceivable. In principle, assembly could also be carried out while keeping a plate open, but this is difficult to implement in practice, so the expansion compensation lugs must ensure sufficient clearance during assembly and can later break away, and may be designed accordingly.

[0028] The problem is also solved by a system comprising at least one profile according to one of the preceding claims and at least one plate-shaped roof covering, in particular comprising at least two profiles and at least one solar cell arrangement and a plate-shaped element, in particular made of plastic.

[0029] Advantageously, both the solar cell assembly and / or plastic plate, on the one hand, and the (first) profile and / or the second profile, on the other hand, each have locking mechanisms designed to secure the solar cell assembly and / or plastic plate within the receptacle against removal. This enables particularly simple and quick assembly and allows for a high degree of modularity.

[0030] Fig. Figure 1 shows two profiles, each connected to a plate-shaped element: a solar cell array on the left and a plastic plate on the right. The plate-shaped element is shown as semi-transparent.

[0031] For assembly, the right profile is first attached by screwing it through recess 2. Then, the left profile with the solar cell is placed on top and also screwed through recess 2. The left part of the right profile forms a second recess and seals against the solar cell. A grid is visible at the bottom edge of the panel and the solar cell. Also shown are the second interlocking sections 3 of the profiles, which secure the panel or solar cell against lifting upwards.

[0032] Fig. 2 showed a representation of a profile with a solar cell as in Fig. 1 Fig. Figure 3 shows an arrangement of many such profiles. Fig. 2. The solar-active areas are illustrated by squares, of which four are each.

[0033] The contact points described below are marked by gray circles and ensure excellent load-bearing capacity of the surface. The grids, which also increase stability, are highlighted by broad gray lines. It is evident that the profiles overlap with the solar cells.

[0034] Fig. Figure 4 shows a side view of the assembly on a wooden board with a foil layer over it. The profiles are screwed to the foil. A starter bracket is screwed to the bottom. A limiting element (Figure 4) secures the profile against slipping, and its interlocking section prevents it from lifting off. The limiting element is part of the support section. The profile rests on the foil via the support section. It can be seen that the profiles overlap with their solar cells.

[0035] Fig. Figure 5 shows a rear view of a profile 1 with a solar cell and a second profile 10. The profile 1 is designed as in the preceding figures. It also shows a limiting element 4 that secures the profile against slipping and its interlocking section 6 against lifting. The limiting element is part of the support section 7.

[0036] It shows a recess 2 and around it concentrically and circularly arranged sealing ribs 8 and around it a rectangular sealing rib arranged concentrically.

[0037] Figure two shows profile 1 as part of a more complex component. In addition to the solar cell arrangement bonded to the profile, it has a second profile 10 which, on the back, forms a labyrinth seal together with the top surface of a first profile of an identical component.

[0038] Fig. 6 shows the first profile from Fig. 5 again individually from different directions. Also visible are the second interlocking section 3, the recess 2, and a limiting element 12, which secures the solar cell arrangement against slipping downwards during bonding and forms impact protection for the solar cell arrangement. The limiting element extends across the entire width of the profile into a second receptacle for receiving a second profile and a solar cell arrangement of an adjacent component during assembly, thus securing the components against each other together with the second interlocking section 3, which also extends across the entire width.

[0039] Fig. Figure 7 shows a detailed view of part of the component. Fig. 4.

[0040] Fig. Figure 8 shows a detailed view of the profile. Fig. 6. Two images can be seen with a bridge in between and the continuous boundary element at the bottom.

[0041] Fig. Figure 9 also shows a detailed view of the profile. Fig. 6 for better visibility of the second interlocking section.

[0042] Fig. 10 shows the right profile from Fig. 1. Three recesses, marked by red arrows and distributed along the longitudinal direction, can be seen for the lateral insertion of a plate with corresponding mushroom-shaped projections, as shown in the final result in Fig. 11 shown, for the formation of the right-hand component from Fig. 1.

[0043] The underside is formed here by the end faces of the outer, longitudinally running ribs that connect them perpendicularly. Protruding from this are the bearing section and the sealing ribs around the recess.

[0044] Fig. 12 shows a detailed view of the profile from Fig. 6, which makes the sealing ribs around the recess more visible.

[0045] Fig. Figure 13 shows a left-hand portion of a first profile on the right and a solar cell array with a second profile on the left. The second profile has small tabs, one of which is visible. These serve as spacers during assembly but can be elastically deformed into the second profile by thermal expansion of the components.

[0046] Fig. Figure 14 illustrates this process from top to bottom.

[0047] Fig. Figure 15 illustrates the size and distribution of the noses in a view of the solar cell array. The noses are indicated by arrows.
