Description

Retaining profile and sealing profile for plate-shaped modules

The invention relates to a retaining profile and a sealing profile for plate-shaped modules, preferably roof modules, as well as a multi-part frame comprising the holding profile and the sealing profile. In particular, the invention is concerned with modular roof mounting systems for photovoltaic systems.

Generic holding and sealing profiles are known from the documents WO 00/02256, DE 10 2004 026 786 A1 or DE 202 17 489 U1.

Roof mounting systems for photovoltaic (PV) are roughly subdivided into rooftop, in-roof, complete roof and flat roof systems. So far Rooftop systems dominate with a market share of 60-70%, because such systems are historically preferred, there are few problems with the tightness, good ventilation and cooling of the modules and thus high yields are guaranteed, and because no good alternatives on the Market are available. Rooftop systems have certain disadvantages. So a stable frame and a stable mounting system to absorb forces necessary, which requires a high material usage. The variety of components requires a complex assembly. In addition, rooftop systems are visually less appealing. The disadvantages mentioned above result in relatively high costs (material and working time) and a low cost-cutting potential.

In-roof systems have previously had a lower market share, because there are only a few suppliers and the large number of components requires complex assembly. Poor ventilation and cooling of the modules causes a 2 - 5% lower yield.

The market for in-roof and full-roof systems is growing in Germany and abroad, because the trend is towards larger systems, which is what in-roof and complete roof solutions are all about. In addition, building-integrated systems are also visually appealing. Intelligent in-roof systems can be produced more economically, since stability does not have to be ensured by the frame and the mounting system, but is taken over by the already existing roof construction. Furthermore, the usual roofing is saved.

Previous in-roof or complete systems are complicated in structure, include many components, require a high assembly costs and are mounted on site on the roof. This makes in-roof systems more expensive than rooftop systems plus roofing. Above all, the high costs are the main reason for the so far low use of roof systems in Germany. Further disadvantages result from the large number of system components, the complicated roof connection, the complex assembly work, the cumbersome installation, a low assembly tolerance and the lack of protection against precipitation of any kind.

The invention has for its object to simplify the assembly of plate-shaped modules of a modular mounting system considerably.

In order to solve the object underlying the invention, the holding profile for plate-shaped modules, preferably roof modules, provided according to claim 1, wherein the holding profile has a one-piece, at least partially flexible profile body made of plastic, which is designed to two adjacent Hold modules on a support structure, preferably a roof substructure, in an overlapping state, so that the profile body extends in sections between the modules. The holding profile forms the central element for mounting the plate-shaped modules. The retaining profile according to the invention enables easy mounting on the support structure, for example by attachment by means of wood screws on the roof battens of the roof substructure, secure fixation of the modules on the support profile, and a slip-off protection and protection against snow loads and gusts. In addition, the holding profile causes an intelligent water flow through shingling or overlapping of the modules. Due to the one-piece design of the profile body optimum tightness is guaranteed. The term "one-piece profile body" is to be understood as meaning that a profile body with cohesively connected sections, in particular a profile body with coextruded sections made of different plastics, is also grasped.Using the flexible properties of the plastic, the modules can be mounted without tools and individual modules in the middle be easily replaced from a module field. In addition, plastic is usually easy to process and does not corrode. A punctiform loading of the modules is avoided and a simple roof connection is made possible. The flexibility of the profile body allows relatively large manufacturing and installation tolerances, so that plate-shaped modules of different thickness can be mounted with one and the same holding profile. In addition, a thermal expansion of the modules can be compensated. The term "at least partially flexible plastic profile body" is understood to mean that the profile body has at least one flexible section but does not have to be completely flexible. The preferred material for the profile body is acrylonitrile / styrene / acrylic ester (ASA). This material is extrudable, weatherproof, chemical and UV resistant.

It may prove to be useful if the profile body is designed such that at least one of the adjacent modules, preferably both modules, engage peripherally in the overlapping state. As a result, a plate-shaped module can be held positively and securely between two holding profiles.

It may prove to be advantageous if the profile body has a substantially S-shaped holding section which defines two substantially U-shaped module receptacles. The terms s-shaped and u-shaped refer to the preferred cross-sectional shape of the profile body. By means of the S-shaped cross-sectional shape, two module receptacles can be implemented whose directions of insertion in different planes are oriented substantially opposite one another, which favors a simple and systematic construction of the modular mounting system from top to bottom.

It may prove practical if the s-shaped holding portion has legs which extend substantially parallel to each other. As a result, the plate-shaped modules can be aligned precisely parallel to one another.

It may prove practical if a leg of the s-shaped holding portion has a flexible tab. As a result, if required, a module can also be introduced transversely to the insertion direction into the associated module receptacle of the profile body, e.g. locked, are what is particularly desirable under the aspect of "tool-free installation".

It can prove to be advantageous if the retaining profile has an anti-theft device, which allows a single insertion of a module and blocks further insertion of the module. This can prevent a module held between two holding profiles from being stolen. Another aspect of the present invention relates to a sealing profile for plate-shaped modules, preferably roof modules, wherein the sealing profile is designed to hold two adjacent modules lying in a plane sealingly, so that the sealing profile extends in sections between the modules. As a result, an arrangement consisting of several plate-shaped modules can be extended as desired to the right and left (verge).

It may prove to be advantageous if the sealing profile has a one-piece, at least partially flexible profile body made of plastic, which is designed to seal two adjacent modules lying in a plane, so that the profile body extends in sections between the modules. The one-piece profile body allows a very fast installation with high stability. It ensures a high degree of tightness. Overall, a simple side connection (verge) can be accomplished.

It may prove helpful if the profile body is substantially H-shaped and defines two substantially U-shaped module receptacles. The designations H-shaped and U-shaped refer to the preferred cross-sectional shape of the profile body. Due to the H-shaped cross-sectional shape, two module receptacles can be implemented whose insertion directions are aligned in a plane substantially opposite to each other, which favors a simple and systematic construction of the modular mounting system while allowing a simple roof connection on the side.

It may prove to be practical if the sealing profile has two one-piece and at least partially flexible profile body made of plastic, which are connectable to keep two adjacent modules lying in a plane sealingly, so that the profile body sections extend between the modules. This makes it possible to premount both sides, whereby the profile bodies are glued to the roof with one plate-shaped module each before installation. Preferably, the two profile bodies are positively and sealingly connectable.

Another aspect of the present invention relates to a multi-part frame for plate-shaped modules, preferably roof modules, comprising at least one retaining profile according to one of the preceding embodiments and a sealing profile according to one of the preceding embodiments. Essentially, the sealing profile fulfills the task of sealing the module or the gap between two modules adjacent to one another in a plane, enabling simple and rapid assembly, and at the same time undertaking the edge protection on the roof by pre-assembly. Optionally, an edge protection profile can be used, which protects the plate-shaped module during transport and installation on site and at the same time performs a sealing function.

The frame according to the invention comprises at least one retaining profile according to the invention and at least one sealing profile according to the invention, and forms, in conjunction with the matching plate-shaped modules, a form-fitting, watertight quick-mounting system. It goes without saying that the holding profile according to the invention and the sealing profile according to the invention can also be used independently of each other.

The frame according to the invention integrates all the essential functions of a mounting system in 2 profiles:

Form-fitting fixation of plate-shaped modules on the roof to safely accommodate all loads such. Wind and snow according to DIN1055;

Safe sealing due to shingling of the modules and shingling of the lateral sealing profiles;

Soft support for the floating mounting of the modules to protect the module edges and the backsheet on PV modules and to compensate for a distortion of the roof substructure;

Flexible tabs or lips for receiving modules of different thicknesses;

Installation with high mounting tolerance (> ± 5 mm, which is more or less the same as with roof tiles) on substructure;

Drainage of liquids that penetrate into a space between the profile body and the module to prevent frost damage; Covering different module thicknesses with only one retaining profile and only one sealing profile taking advantage of the flexibility of the profile body (especially the soft pads and the sealing portions) and using compensating profiles (or adapters) and / or edge protection profiles, which are attached to the edges of the modules to thickness differences to compensate.

Tool-free installation of the modules;

Tool-free installation of the sealing profiles.

The frame according to the invention has the advantage that no terminals, screw, adapter, strips and additional horizontal and support sealing profiles are needed. Moreover, an intelligent water drainage can be accomplished. The frame according to the invention can be assembled by adapted lengths of the retaining profile according to the invention and the sealing profile according to the invention easily to any module size. The same profiles can also be used for roof connections above (first), below (eaves) and right and left (verge). Without additional installation effort, effective theft protection can be accomplished. In addition, there are design freedoms, z. B. with regard to the color of the profiles.

It may be advantageous if the profile body of the holding profile and / or the sealing profile is formed as an extruded profile or extrusion profile. Such profiles can be produced in the required quantities at relatively low cost.

It may prove to be practical if a reinforcing insert is embedded in the profile body of the holding profile and / or the sealing profile. As a result, the strength of the profiles can be increased, which is quite desirable in view of extreme weather events (hail, storm, etc.). The reinforcing insert is preferably a metal profile with a matched to the cross-sectional shape of the profile body cross-sectional shape. Preferred materials for the reinforcing insert are stainless steel, aluminum or sheet steel. Through intelligent combination of different materials, the different properties of metal (high mechanical and thermal stability) and plastic (flexibility, sealing, insulation and passivation properties) can be optimally combined and integrated into a profile. By embedding the reinforcing insert in the profile body, the reinforcing insert can be protected against corrosion and weathering. The Oichtprofil increases the stability of the module against deflection, especially in the vertical assembly of modules. This can be achieved, for example, by a strong metal insert or by attaching the sealing profile to the roof structure.

It may prove to be advantageous if the profile body of the holding profile and / or the sealing profile has a contact portion for point and / or line-shaped contacting of a module. It may prove to be particularly advantageous if the profile body has a plurality of contact sections for point and / or line-shaped contacting different sides of a module. As a result, a coarse sealing of the profile body in cooperation with the module can already be achieved with respect to solids (foliage, etc.).

It may prove useful if the profile body of the holding profile and / or the sealing profile has a soft support for contacting a module. The soft support is preferably formed on an inner side of a module receptacle, preferably coextruded. The soft support is preferably made of a different, preferably softer plastic than a lying behind section of the profile body, on which the soft support is formed. Preferred materials for soft contact are thermoplastic elastomer (TPE) or acrylonitrile / styrene / acrylic ester (ASA) with SoftTouch (chemical and UV resistant). The soft support serves for the floating storage of the modules in order to protect the module edges and the backsheet for PV modules, and to compensate for a delay of the roof substructure. In addition, the soft support allows, within certain limits, compensation for variations in module thickness or thickness, so that modules of different thickness and / or thickness can be accommodated in one and the same profile body. The soft pad is preferably dimensioned so that all commercially available crystalline PV modules (e.g., 5 mm to 7 mm thick) can be sealingly received.

It may prove advantageous if the profile body of the holding profile and / or the sealing profile has a sealing portion for sealing a gap between the holding profile and a module. As a result, a finer sealing of the profile body in cooperation with the module against liquids (precipitation, etc.) can be accomplished. The sealing portion is formed, for example, in an opening region of a module receiving, preferably coextruded. The sealing portion consists of a different, preferably softer plastic than a section of the profile body lying behind, on which the sealing portion is formed. Preferred materials for the sealing section are thermoplastic elastomers (TPE) or acrylonitrile / styrene / acrylic ester (ASA) with SoftTouch (chemical and UV resistant).

It may prove to be practical if the profile body of the holding profile and / or the sealing profile has a lamination. The lamination is preferably a UV and / or weather-resistant plastic film, such as polyvinylidene fluoride (PVDF) or polymethyl methacrylate (PMMA), which is applied to a weather side of the profile body. The lamination accomplishes an effective UV protection and allows an individual color design of the profile body, e.g. in coordination with a color of the modules.

It can prove to be helpful if the profile body of the holding profile and / or the sealing profile has a drainage device in order to allow liquids that penetrate into an intermediate space between the profile body and the module to drain. This can prevent frost damage. The drainage device is designed, for example, as a bore penetrating the profiled body, which bore is arranged in such a way that the liquid drains under the influence of the force of gravity when the profiled body is arranged as intended (for example on a roof substructure). In the case of the profile body of the upper profile, the drainage device is designed, for example, as a bore penetrating the bottom of the upper module receptacle, which is preferably lined with corrosion-resistant material in order to protect any reinforcing insert which may be present from corrosion. The drainage device can also be accomplished in such a way that, when the profile body is arranged as intended (for example on a roof substructure), the liquid runs under the influence of the weight force between the module and contact sections and / or soft supports.

A method described herein for mounting a modular system with at least one plate-shaped module using the holding profile according to one of the preceding embodiments, comprises the steps:

a) attaching retaining profiles to the support structure, at a distance which corresponds approximately to the distance between two opposite edges of the plate-shaped module; b) introducing an edge of the plate-shaped module into a receptacle of a holding profile; and

c) introducing an opposite edge of the plate-shaped module into a receptacle of another holding profile, so that the plate-shaped module is held in a form-fitting manner between the holding profiles.

This method allows the tool-free installation of a module between two retaining profiles without the introduction of additional rubber profiles with sealing properties. The elimination of the use of tools and the shorter time required cause a significant reduction in the cost of the method over conventional methods for mounting a modular system with at least one plate-shaped module.

Using sealing profiles, the arrangement formed by the method of two holding profiles and a module from left to right is arbitrarily expandable.

The features of the preferred embodiments of the invention will be explained below with reference to the accompanying drawings:

Detailed Description of the Preferred Embodiments

Figure 1 shows a not to scale, perspective view of the modular system 1, comprising four plate-shaped roof modules 3 with edge enclosing edge protection profiles 5. Each one of the top two roof modules 3 and one of the lower two roof modules 3 are held by an inventive retaining profile 2 in the overlapping state. Two laterally adjacent in a plane roof modules 3 are each sealingly connected by an inventive sealing profile 4. The sealing profiles 4 are also shingled or arranged in the overlapping state.

It goes without saying that the position-indicating terms, such as top, bottom, left, right, front, back, inside, outside, which are used in the context of this description, refer to the respective view and beyond have no binding character.

The retaining profile 2 according to the invention is designed for plate-shaped modules, preferably roof modules. Modularity is the division of a whole into parts. The parts are called modules, components or components. In a modularized design, complete systems are assembled from standardized individual components. In the context of the present invention, modular systems with plate-shaped modules and in particular modular roof mounting systems for photovoltaic systems with plate-shaped photovoltaic modules are concerned. However, the principle of the invention is not limited to the field of photovoltaic (PV), but is applicable to other fields of technology in which plate-shaped modules are used. In particular, the principle of the invention is applicable to the field of blanketing.

The holding profile 2 according to the invention comprises a one-piece, at least partially flexible profile body 21, 22 made of plastic, which is designed to hold two adjacent modules 3 on a support structure 7, preferably a roof substructure, in an overlapping state, so that the profile body 21, 22 extends in sections between the modules 3 and the modules 3 surrounds the edge. The term overlapping state is to be understood as meaning that two adjacent plate-shaped modules extend in different, preferably substantially parallel, planes, wherein a module in a view orthogonal to the plane of the module at least partially conceals the adjacent module. The overlapping state of adjacent plate-shaped modules is shown clearly in FIGS. 2 a, 2 b and 5 to 7.

The term "encompassing the edge" is to be understood as meaning that the profile body 21, 22 extends in sections on both sides of the module 3, ie both the outside and the inside of the module 3. As a result, the module 3 can form-fit between two retaining profiles 2 being held.

FIG. 2a shows a sectional view of the retaining profile 2 according to the invention according to variant A for modules 3 with edge protection profile 5, two modules 3 with edge protection profile 5 adjacent over the shorter side being intended to be held in the overlapping state according to FIG.

FIG. 2b shows a sectional view of the retaining profile 2 according to the invention according to variant B for modules 3 without edge protection profile, wherein two modules 3 without edge protection profile adjacent to one another over the shorter side are intended to be held in the overlapping state according to FIG.

The edge protection profile 5 according to FIG. 4 can optionally be used to protect the plate-shaped module 3 during transport and assembly on site and at the same time to assume a sealing function. The edge protection profile 5 comprises a U-shaped cross section and is made of plastic. The edge protection profile 5 can be used as an adapter for different module thicknesses.

Seen in cross-section, the profile body of the retaining profile 2 comprises a fastening section 21 which can be fixed to the retaining structure 7, and a substantially s-shaped retaining section 22 which defines two substantially U-shaped module receptacles. The s-shaped holding portion 22 comprises three legs 24 which extend substantially parallel to each other and define therebetween the module receptacles. At the top, free leg 24 of the S-shaped holding portion 22, a sealing portion 26 is formed, which forms a flexible sealing lip or tab. The tab is deformable such that the module in the proper assembly, which is shown schematically in Figure 8, with displacement of the flexible tab 26 can be latched transversely to the intended insertion in the upper module receiving the lower retaining profile 2. The attachment portion 21 extends essentially in the direction of escape of the lowermost leg 24 of the s-shaped holding portion 22, and forms with this leg a substantially flat support surface 23 of the holding profile 2. At the bottom of each module receptacle, opposite the mouth, and in sections to the Inner sides of the module receptacle are formed on soft pads, preferably coextruded. The soft support consists of a softer plastic than a lying behind it section of the profile body, on which the soft support is formed. Preferred materials for the sealing section and the soft support are TPE or ASA with Soft-Touch (chemical and UV resistant).

According to variant A, the distances between the legs 24 are dimensioned such that the module 3 can be positively accommodated with attached edge protection profile 5. In this case, the holding profile 2 in the lower module receiving contact portions 25 for point and / or line-contacting different sides 31, 32 of the module 3, wherein the edge protection profile 5 can engage positively behind the contact portions 25. The contact portions 25 are arranged such that the module can be levered with attached edge protection profile 5. In the upper module receiving a contact portion 25 for point and / or line-shaped contacting of the inner side 32 of a module 3 is provided, wherein the edge protection profile 5 can be levered behind the contact portion 25 and under the leg 24 and engage positively. The edge protection profile serves not only the edge protection but also the compensation of different module thicknesses, so that modules of different thickness or thickness can be held with only one holding profile and only one sealing profile.

The preferred dimensions of the holding profile according to the invention according to variant A for a module 3 with a thickness (= distance between outside 31 and inside 32) of 5 mm are explained below with reference to FIG. 2a. The support surface 23 has an extension in the image plane of 90 mm, wherein the fixing portion 21 is about 40 mm long and the lowermost leg 24 of the holding portion 22 is about 50 mm long. The inner sides of the lower module receiving leg defining 24 have a distance of 9 mm, wherein the contact portions 25 protrude about 2 mm above the respective inner sides of the legs 24 and have a vertical distance of 5 mm. The distance between the inner sides of the upper module receiving leg forming 24 is also 9 mm, the contact portion 25 protrudes from the central leg by 2 mm upwards. At the upper leg 24, a flexible tab is formed, wherein the free end of the flexible tab has a distance from the central leg 24 of about 8.5 mm. As a result, the edge protection profile 5 engage positively behind the contact section 25 and the flexible flap.

According to variant B, no contact portions 25 are provided. Tolerance compensation is accomplished via sealing portions 26 and / or soft pads. The other features essentially correspond to variant A.

In a preferred embodiment, the retaining profile 2 comprises an anti-theft device 28, which allows a single insertion of a module and blocks further insertion of the module. In this case, the anti-theft device 28 can be transferred from a non-activated state, in which insertion of a module 3 is possible, into an activated state, in which insertion of a module 3 is blocked.

The structure and operation of the anti-theft device 28 will be explained below with reference to FIG. 8.

In the present example, the anti-theft device 28 is an insertion profile or a metal insertion clip, which is arranged in the lower module receptacle of the profile body 21, 22. The insert profile has a substantially rectangular cross section with two shorter legs 28a and two longer legs 28b in the non-activated state. The longer legs 28b are biased against each other and are spaced by a shorter leg 28a, which is movable with respect to a longer leg 28b and slightly inclined towards an enclosed cavity 28c. The leg 28a is thereby frictionally held in the upright position shown in Fig. 8a. Upon first insertion of the module 3, the leg is folded inwardly from the upright position shown in Figure 8a, while a front edge 33 of the module 3 enters the space 28c between the longer legs 28b. Upon removal of the module 3 from the anti-theft device 28, the bias of the longer legs 28b causes the longer legs 28b to be pressed against each other and form a tip directed counter to the insertion direction so that the module 3 will no longer enter the space 28c between the longer legs 28b can penetrate.

The multi-part frame according to the invention for plate-shaped modules 3, preferably roof modules, comprises at least one retaining profile 2 according to one of the embodiments described above and a sealing profile 4.

The sealing profile 4 according to the invention can be manufactured in one piece or in two parts. When one-piece profile two opposite U-shaped sealing surfaces are provided so that the profile can not slip out. This also allows a simple side connection (verge). The two-part profile a total of three sealing surfaces are provided, with a seal of the sealing profile to both adjacent modules 3 and between the two parts of the sealing profile 4 is required. The two-part construction of the sealing profile enables pre-assembly of both sides. For this purpose, preferably a part of the sealing profile is glued firmly using a butyl adhesive using a module. Butyl stops the diffusion of water. In the simplest case, by separating the one-piece profile and attaching a fold or double fold (as in the case of bricks), a two-part profile can be produced.

Two variants of a sealing profile 4 of the multi-part frame according to the invention are shown in FIG. 3a and FIG. 3b:

The one-piece sealing profile 4 will be explained in more detail below with reference to FIG. 3a. The profile body 41 is formed substantially H-shaped so as to hold two adjacent modules 3 lying in a plane sealingly, so that the profile body 41 extends in sections between the modules 3. Each two legs 44 extending substantially parallel define a module receptacle. The legs 44 each have a free length of about 13 mm, each protruding at the free end sealing portions 46 in and against a direction of insertion into the module receptacle. The sealing portions 46 are integrally formed in the mouth region of each module receptacle, preferably coextruded. Each of the sealing sections 46 preferably consists of a different, preferably softer, plastic than a section of the profile body 41 lying behind, on which the sealing section 46 is formed. Two U-shaped reinforcing inserts 47 made of metal (eg aluminum foil with 0.5 mm thickness) are embedded in the profile body 41 such that the legs of each reinforcing insert 47 extend within the opposite legs 44 of a module receptacle. At the bottom of each module receptacle, opposite the mouth, a soft pad 45 is formed, preferably coextruded. The soft support 45 is made of a softer plastic than a section of the profile body 41 lying behind, on which the soft support 45 is formed. Preferred materials for the sealing portion 46 and the soft pad 45 are TPE or ASA with SoftTouch (chemical and UV resistant).

The two-part sealing profile 4 will be described below with reference to Figs. 3b and 3c. The two-part sealing profile 9 comprises two identical, one-piece and at least partially flexible profile body 91 made of plastic, which are positively connected to hold two adjacent modules 3 lying in a plane sealing, so that the profile body 91 sections extend between the modules 3. Each profile body 91 comprises a substantially U-shaped connecting portion 92 and a substantially U-shaped receiving portion 93. The connecting portion 92 and the receiving portion 93 have at least one common leg. A connecting direction in which the profile bodies 91 can be connected, and a plug-in direction in which a module 3 can be inserted into a module receptacle of a profile body 91, extend substantially perpendicular to one another. The connecting portion 92 and the receiving portion 93 are partially provided with an integrally formed, preferably co-extruded, plastic jacket. The plastic jacket forms sealing portions 96 in the mouth region of each receiving portion 93 and sealing portions in the region of the connecting portion 92. A U-shaped reinforcing insert 97 made of metal (aluminum foil with 0.5 mm thickness) is embedded in the receiving portion 93 of each profile body 91 such that the legs of the reinforcing insert 97 extend within the opposite legs 94 of a module receptacle. At the bottom of each module receiving a soft pad 95 is formed, preferably coextruded. The soft support 95 consists of a different, preferably softer plastic than a section of the profile body 91 lying behind it, on which the soft support 95 is formed. Preferred materials for sealing portion 46 and soft pad 95 are TPE or ASA with SoftTouch (chemical and UV resistant). In the connected state according to FIG. 3 c, no part of the connecting portion 92 or the receiving portion 93 is exposed inwardly or outwardly. The sealing profile 9 is held in the sealed state between two in-plane modules.

The dimensions of the holding profile 2 and the sealing profile 4, 9 are matched to the dimensions of the plate-shaped module 3, so that the desired holding, hedging and sealing functions are ensured. The profile body of the holding profile 2 and the sealing profile 4, 9 is preferably an extrusion profile made of plastic, preferably ASA. Depending on requirements, the retaining profile 2 and / or the sealing profile 4 can be modified to meet various requirements: For example, the profile body 21, 22; 41, 91 of the holding profile 2 and / or the sealing profile 4, 9 a reinforcing insert 27; 47, 97 included. In addition, the profile body 21, 22; 41, 91 of the holding profile 2 and / or the sealing profile 4, 9 have a contact portion 25, 45 for point and / or linienför- shaped contacting a module 3. The contact sections 25, 45 are preferably provided on both sides of a module receptacle in order to positively receive a module 3 provided with an edge protection profile 5 so that the legs 24, 44 defining a module receptacle extend parallel to the module 3 and the contact sections 25, 45 come into contact with an outside 31 or inside 32 of a module 3 point and / or line, as can be seen for example in Figure 2a.

A method for assembling a modular system with at least one plate-shaped module 3 using the holding profile 2 according to one of the preceding embodiments, comprises the steps:

a) fastening of retaining profiles 2, 2 'to the support structure 7, at a distance which corresponds approximately to the distance between two opposite edges 33, 34 of the plate-shaped module 3;

b) introducing an edge 33 of the plate-shaped module 3 into a receptacle of a holding profile 2; 2 '; c) introducing an opposite edge 34 of the plate-shaped module 3 in a receptacle of another holding profile 2 ', so that the plate-shaped module 3 is positively held between the holding profiles 2, 2'.

The method will be described in detail below with reference to FIG. 8, wherein FIG. 8 schematically shows the working steps in the assembly of a plate-shaped module 3 between two holding profiles 2.

First, a plurality of retaining profiles 2, 2 'are mounted on a roof substructure 7. For this purpose, the contact surface 23 of the profile body of each retaining profile 2, 2 'is applied to a bearing surface 71 of a roof batten 7. Subsequently, a fastening means 6 is screwed through the attachment portion 21 in the roof batten 7. The distance between the upper retaining profile 2 and the lower retaining profile 2 'is to be dimensioned such that the steps described below are executable.

FIG. 8 a shows views of an upper holding profile 2 and of a lower holding profile 2 'during the insertion of an upper edge 33 of the plate-shaped module 3 into a receptacle of the upper holding profile 2.

To see is an inventive retaining profile 2 according to variant B for plate-shaped modules 3 without edge protection profile. The profile body is reinforced with two reinforcing inserts 27 (aluminum 0.7 mm). In the lower module holder is the anti-theft device 28 with a substantially rectangular cross-section. The anti-theft device 28 is in the non-activated state, wherein the two longer legs 28b are kept at a distance. The right in the drawing, shorter leg 28a is movable relative to the upper, longer leg 28b and is held in the state shown in FIG. 8 non-positively in the upright position.

The front edge 33 of the module 32 is now inserted into the lower module receptacle of the upper retaining profile 2, while the rear edge 34 is located outside the upper module receptacle of the lower retaining profile 2 ', as can be seen in the right half of Fig. 8a. The module 3 is now moved from the position shown in Fig. 8a in the position shown in Fig. Δb, wherein the front end 33 of the module 3 penetrates into the space 28c between the longer legs 28b of the insert profile 28 and thereby the movable, shorter Leg 28a pushes inward and folded. The front end 33 of the module 3 is inserted to the stop. The distance between the upper retaining profile 2 and the lower retaining profile 2 'is to be dimensioned such that the rear edge 34 of the module 3 in the upper module receiving the lower retaining profile 2' can be inserted when the front end 33 of the module until it stops in the lower module receiving the upper retaining profile 2 is introduced. Nevertheless, a flexible tab is integrally formed on the upper leg 24, which can be deformed such that the rear edge 34 of the module 3 can be locked by displacing the flexible tab transversely to the intended insertion in the upper module receiving the lower holding section 2 '.

Subsequently, the module 3 is transferred from the position shown in Fig. 8b in the position shown in Fig. 8c, wherein the front end 33 of the module 3 is pulled out of the Einlegepro- fil 28 and in the upper module receiving the lower retaining profile 2 'completely locks. When the front edge 33 of the module is pulled out of the insertion profile 28, the longer legs 28b of the insertion profile 28 are pressed against one another by their own biasing force in order to block access to the space 28c located between the longer legs 28b. This activated state of the thief-steel fuse 28 is shown clearly in Fig. 8c.

The anti-theft device 28 and the distance of the holding profiles 2, 2 'is dimensioned so that the module 3 is held in the position shown in Fig. 8c positively between the upper Haiteprofil 2 and the lower support section 2' and not further into the lower receptacle of the upper retaining profile 2 can be inserted. Consequently, the between see the holding profiles 2, 2 'positively held module 3 can not be removed. With adjacent modules 3 is moved in the same way.

In the position shown in FIG. 8c, the module 3 is arranged as intended with respect to the retaining profiles 2, 2 'and is sealed by sealing sections or sealing lips 26 relative to the upper retaining profile 2 and the lower retaining profile 2', as shown clearly in FIG. 8c , Other plate-shaped modules can be mounted in the same way. The arrangement can be extended upwards and downwards as well as left and right as desired. In an extension of the arrangement to the left and right is adjacent to the first plate-shaped module module according to the sequence of steps a) to c) to assemble, see between the modules lying in a plane, a sealing profile according to the invention is to be arranged sealingly. In an extension of the arrangement up and down further holding profiles are provided, which is to proceed according to the sequence of steps a) to c). The upwardly and downwardly adjacent modules and sealing profiles are arranged in the overlapping state, so that rainfall does not assume any undesired flow directions.

The connections to ridge and eaves can be easily accomplished:

6 shows schematically a ridge-side connection of the retaining profile 2 according to the invention. The profiled body of the retaining profile 2 comprises the fastening section 21 and the essentially s-shaped retaining section 22, wherein the fastening section 21 forms the bearing surface 23 of the retaining profile 2 with a leg 24 of the retaining section 22 , with which rather the retaining profile 2 rests against a roof substructure (not shown). The uppermost module 3 is received in the lower module receptacle of the holding profile 2, wherein the sealing lip 26 seals a gap between the holding profile 2 and an outer side 31 of the module 3. An inner side 32 of the module 3 faces the roof substructure (not shown). The roof connection on the ridge side is effected by a folded sheet 85, which extends from ridge tile 83 to the top retaining profile 2. The length of the ridge plate 85 is independent of the module length. An additional retaining profile 2 is not required. A ridge batten 84 is located under the ridge tile 83. The ridge plate 85 protrudes under the ridge bat 84 and under the ridge tile 83, wherein the lower end of the ridge plate 85 behind the contact portion 25 positively engages between two legs 24 of the retaining profile 2.

The connection to the eaves is effected by a folded sheet 81 from the bottom retaining profile 2 to the gutter 82. The length of the sheet 81 is independent of the length of the module 3, so that no additional profile 2 is necessary. The eaves sheet 81 is received in the lower receptacle of the holding profile 2 such that the folded end of the eaves sheet 81 with the contact portion 25 is in point and / or line contact. The attachment portion 21 forms with a leg 24 of the holding portion 22, the support surface 23 of the retaining profile 2, with which the retaining profile 2 rests against the roof substructure (not shown). The attachment portion 21 is fixed to the roof substructure with a fastener (not shown). The module 3 is arranged in the manner described above between the upper module receiving leg defining legs 24 of the holding profile 2, so that the outer side 31 of the module 3 faces outward and the inner side 32 of the module 3 faces the roof substructure. The lowermost module 3 and the eaves sheet 81 as well as the eaves sheet 81 and the gutter 82 are arranged in the overlapping state, so that precipitation can not assume an undesired flow direction.

The lateral roof connection is accomplished on both sides with the sealing profile according to the invention. For this purpose, a folded sheet metal for the lateral roof connection in a module receiving the sealing profile is positively received. The upwardly and downwardly adjacent modules and sealing profiles are arranged in the overlapping state. An additional profile is therefore not necessary.

The invention has the potential to bring the total cost of a building-integrated photovoltaic system (in-roof, complete roof and possibly also facade system) below the cost of an on-roof system. This is achieved by the favorable production of the profiles (by extrusion), the small number of components, the low assembly work, a faster and easier installation on the roof with high mounting tolerance, a top-down mounting, a tool-free assembly of the modules, a simple roof connection to ridge, eaves and verge, as well as a simple and flexible design of the plant. Furthermore, the invention allows a high degree of freedom in terms of design, for. B. by a color adjustment and an adaptation of the Ania- gengröße to local conditions. Furthermore, it is possible shaded areas with dummies, z. As simple glass panes, and thus improve the yield and appearance of photovoltaic systems. The modules 3 mounted with the holding profile according to the invention can be subjected to a high degree of static load, with values of up to 5,400 N / m ^{2 being} achievable. The retaining profile 2 according to the invention guarantees optimum shingling and tightness.
