Description

[0001] The invention relates to a mounting system for wind suction-proof fastening of solar modules on roofs. STATE OF THE ART

[0002] EP 2 194 335 A1 discloses a mounting system for solar collectors. The mounting system comprises a multitude of individual components, the assembly of which requires various tools. The available components allow only a limited range of applications.

[0003] DE 202 04 963 U1 describes a mounting device for collectors using a roof anchor. The described device does not offer universal application. TASK

[0004] The present invention is based on the object of creating a mounting system that accommodates virtually any type of solar module and allows for simple and secure attachment of the modules, which can be achieved with just a few simple steps. The mounting system should enable the creation of a permanent functional surface in which the solar modules are mounted without tension while still being stable against wind forces. Furthermore, it should be resistant to weather and atmospheric influences, preventing waterlogging and thus preventing moss growth.

[0005] This object is achieved by a mounting system according to the proposed claim 1.

[0006] Further advantageous details and embodiments of the invention as well as further developments and variants are apparent from the dependent claims and the drawing explained below. ADVANTAGES OF THE INVENTION

[0007] According to the invention, a mounting system for the wind suction-proof fastening of solar modules on roofs is proposed, with means for fastening to the existing roof substructure, which emerges under the roof covering, projects above the roof covering and forms a support device for the substructure for receiving the solar elements and comprises a roof hook for fastening to the roof substructure, a base profile for forming the substructure, an insert profile for receiving the solar modules and for forming part of the substructure and a profile connector for connecting the base profile to the insert profile, which are used in a quantity determined according to the installation area of ​​the solar modules.

[0008] The invention is characterized in that the insert profile is clipped into the profile connector, wherein the profile connector is designed in several parts and has means which fix both the profile connector on the base profile and the insert profile on the profile connector by the contact force of a screw.

[0009] The invention achieves several advantages. Installation is possible from above using just one tool, and there are only a few attachment points. Despite being wind-resistant, the solar modules are installed and secured in a floating, tension-free manner. Wind influences prevent rattling, nor can the components become loose. Furthermore, the system is weather-resistant.

[0010] Only one tool is required for installation, as all system components can be pre-assembled prior to installation. This is particularly advantageous when working on roofs.

[0011] Preferably, the profile connector consists of a receptacle, a clamp, and a clasp, along with the screw. The screw provides the fixing, with the clamp exerting the clamping force on the insert profile, not the screw itself.

[0012] A preferred embodiment of the invention provides that the receptacle consists of a trough with a receiving bed enclosed by a piping and a hook and a hood arranged on the receptacle. The hood allows the clamp to be accommodated, which creates the connection to the base profile, while the piping and the hook serve to engage behind the insert profile. This function is supplemented by the clamp placed on the hood having a U-shaped cross-section with an angled flange that protrudes into the receiving bed of the receptacle and engages over the hook of the receptacle. When the screw is tightened, the clamp is both spread and tightened and the flange of the clamp applies pressure to the insert profile. The screw therefore only has an indirect tightening force and cannot damage the insert profile.

[0013] A preferred embodiment of the invention provides that the clasp has a U-shaped cross-section and at the free ends of its parallel walls each has a hook-shaped foot, which has a mushroom-shaped head on the outside and a shoulder towards the profile interior, wherein a threaded bore (58a) is recessed in the profile cover.

[0014] When the screw is tightened, the brace is also pulled upwards, which further increases the clamping forces already exerted by the expansion.

[0015] A preferred embodiment of the invention provides that the insert profile is rod-shaped and comprises a connecting base and a surround. A strip is arranged on one side of the connecting base in the longitudinal direction of the rod, and a hook is arranged on the opposite side. These strips engage under the piping and the hook on the holder, as well as the flange of the clamp, thus enabling a clip connection between the two parts.

[0016] A further preferred embodiment of the invention provides for a separating strip to rise on the connection base of the insertion profile. This separating strip is limited at the top by a cover. Together with support struts extending from the connection base, this strip forms the enclosure. This geometric design allows the solar modules to be inserted, which are then enclosed in a concealed manner.

[0017] A particularly preferred embodiment of the invention provides for drainage holes to be provided through the separating strip of the insert profile at the transition to the connecting base. This prevents water accumulation.

[0018] Another particularly preferred embodiment of the invention provides for a spacer to be inserted into the frame of the insert profile. This spacer compensates for the necessary clearance between the solar modules and the supporting structure, thus preventing rattling under wind influences, since the solar modules cannot be moved by wind force alone.

[0019] Preferably, the spacer is a bridge-like bar that is raised on feet on both sides. A pin that can be removed via predetermined breaking points is arranged on the bar. The spacer can thus exert a preload on the solar modules, with the pin protruding between two modules and creating the necessary distance there. At the same time, the spacer can also be inserted at the edge. The pin is then broken off so that it does not obstruct the end panels to be installed. The bridge of the spacer is flexible, which allows for longitudinal expansion of the solar modules, as a floating installation is achieved.

[0020] A preferred embodiment of the invention provides that the roof hook consists of a mounting bracket, a support arm, and a boom. The mounting bracket has a hollow chamber profile with a cross groove extending in the longitudinal direction of the profile and open at the top. In this groove, a threaded plate is accommodated for longitudinal displacement, to which the support arm accommodating the boom is attached. This allows any desired grid to be created for a solar module surface.

[0021] A further preferred embodiment of the invention provides that the base profile has a U-shaped cross-section, with facing lugs arranged at the free ends of its flanges. These serve as retaining means for the feet of the brace.

[0022] Further advantages and advantageous embodiments of the invention can be found in the following description, the drawings and the claims.

[0023] There are various possibilities for advantageously embodying and developing the teachings of the present invention. Reference is made, on the one hand, to the subordinate claims and, on the other hand, to the following explanation of an embodiment of the invention with reference to the drawing.

[0026] The Fig. Figure 1 shows the mounting system 1 according to the invention, which is used on a pitched roof. Essentially, the mounting system 1 consists of, among other things, a roof hook 10, a base profile 40, a profile connector 60, and an insert profile 90. A roof hook 10 is fastened to a wooden roof batten 7 of the supporting roof substructure by means of screws 8. According to a specific installation pattern, which depends on the type and size of the solar modules 5 to be installed, a plurality of roof hooks 10 are mounted in a predetermined grid (see also Fig. 43). The roof hooks 10 serve as supports for the base profiles 40 to be attached to them. The profile connectors 60 are mounted on these, into which the insert profiles 90 are inserted. These, in turn, serve to accommodate the individual solar modules 5.

[0027] Before the individual assembly steps are explained, the following detailed drawings describe the system components mentioned.

[0028] The Fig. 2 to 5 show the roof hook 10. This consists of a mounting bracket 11, a support arm 21 and a boom 31.

[0029] The one in the Fig. The mounting bracket 11 shown in Figures 6 to 8 is a hollow chamber profile 12 with a leg 13 projecting upwards, preferably at a right angle, which is penetrated by through holes 14.

[0030] The hollow chamber profile 12 has a cavity 15 extending in the longitudinal direction of the profile and a cross groove 16 running parallel thereto, which has an opening 17 at the top of the hollow chamber profile 12. A grid surface 18 is arranged on the top of the hollow chamber profile 12. This is formed by grooves 19 running parallel in the longitudinal direction of the profile.

[0031] The support arm 21 according to the Fig. 9 to 11 has a Z-shaped cross-section with a diagonal web 22, at the ends of which two flanges 23, 24 are arranged, which are aligned parallel to one another but pointing away from one another. The upper flange 23 in the picture has a grid surface 26 on its underside, which is formed from grooves running alongside one another. An elongated hole 25, aligned from the front edge 30 to the web 22, passes through the upper flange 23. The web 22 starts at the upper flange 23 with a section 22a that is orthogonal to it and merges into a slightly angled section 22b, which then starts at the other end, at the lower flange 24 in the picture. The lower flange 24 has a threaded hole 27 through it and has a shoe-shaped depression 29 at its free end. On the underside of the lower flange 24 there is a further grid surface 28, which in turn is formed by grooves running parallel to one another.

[0032] The one in the Fig. The bracket 31 shown in Figures 12 to 15 has an L-shaped cross-section with a leg 32 (lower in the figure) and an upstanding web 33 which forms an angle α with the leg 32 that is greater than 90°. At its free end 34, the web 33 is slightly bent and penetrated by a threaded bore 35. The lower end of the web 33, shown in the figure, merges into the leg 32 with its slightly inclined orientation, with a stepped shoulder 36 being provided at the transition. The leg 32 is penetrated by an elongated hole 37 and has, on its upper side 38 facing the web 33, a grid surface 39 which in turn is formed by parallel grooves.

[0033] The roof hook components are in the Fig. 2 to 5 in the pre-assembled state. To connect the mounting bracket 11 with the support arm 21, a threaded plate 140 is inserted into the cross groove 16. The threaded plate 140 is in the Fig. 39 to 41. Using the system screw 150 ( Fig. 34-38), which is screwed into an internal thread 141 of the threaded plate 140, the connection between mounting bracket 11 and support arm 21 is established.

[0034] The Fig. 16 and Fig. 17 shows the base profile 40. This has a U-shaped cross-section. The profile base 41 is penetrated by elongated holes 42 aligned in the longitudinal direction of the profile and arranged one behind the other. Flanges 43, 44 extend on both sides of the profile base 41, each with a lug 45, 46 integrally formed on its free end. The lugs 45 and 46 are directed toward each other, forming a shoulder 45a, 46a opposite the flanges 43, 44. A slot 47 runs between the two lugs 45, 46 in the longitudinal direction of the profile, opening the chamber 49 of the base profile 40 at its ceiling 48.

[0035] The Fig. Figures 18 to 26 show the profile connector 60, which consists of three components: a receptacle 61, a clamp 75, and a clip 85.

[0036] Recording 61 ( Fig. 18, Fig. 19 and Fig. 25, Fig. 26) comprises a tub 62 and a hood 63 formed thereon. The tub 62 surrounds a receiving bed 64, which is bordered by a piping 65 on one side and a hook 66 on the side closest to the hood 63. The transition between the tub 62 and the hood 63 is formed by a diagonal strip 67, which extends into the first side wall 68 of the U-shaped hood 63. A second side wall 69 lies parallel to the first side wall 68 and is connected to the opposite wall 68 by a ceiling 70. A bore 71 passes through the ceiling 70.

[0037] Terminal 75 ( Fig. 20, Fig. 21, Fig. 25, Fig. 26) has a U-shaped cross-section with a crosspiece 76 penetrated by a bore 83 and with flanges 77, 78 arranged on both sides. A nose 79 rises on the crosspiece 76. The flange 77 extends downwards orthogonally to the crosspiece 76 and has an outer side 80 that slopes inwards, giving the flange 77 a wedge shape. On its inner side, the flange 77 has a cam 81. The flange 78 and the crosspiece 76 form an obtuse angle β with each other due to their alignment, with the flange 78 having a bent portion 82 at its free end.

[0038] The Fig. Figures 22 to 24 show the clip 85. This has a U-shaped cross-section and encloses a cavity 86 with a lower chamber 86a and an upper chamber 86b. The two chambers are separated from each other by separating webs 87, 88 projecting into the cavity 86, which are directed towards each other and enclose a narrowed passage 89 between them. The cavity 86 of the clip 85 is enclosed by a profiled ceiling 58, through which a threaded bore 58a passes, and two parallel walls 56, 57. At their free ends, the walls 56, 57 each have a hook-shaped foot 54, 55, which largely close the cavity 86 on its underside, leaving only a slot 53 open. As a result, the feet 54, 55 each form a shoulder 51, 52 relative to the walls 56, 57. Grooves 56a, 57a are recessed in the walls 56, 57, which, among other things, contribute to the feet 54, 55 receiving a mushroom-shaped head 54a, 55a.

[0039] In the Fig. 25 and Fig. Figure 26 shows the preassembled profile connector 60. The cover 68 of the holder 61 is encompassed by the clamp 75. The cover 68 accommodates the clip 85. In this situation, the holes 71, 83 and the threaded hole 58a are positioned coaxially one above the other, so that the screw 84 can be inserted here.

[0040] In the Fig. 27 to 29, the insert profile 90 is shown. Essentially, the insert profile 90 consists of a connecting base 91 and a surround 92. The connecting base 91 is a rod profile that can be designed as a tube. With increased wall thickness, the profile can also be open at the bottom. Extending along its rod length on the connecting base 91 is a strip 93 on one side and a hook 94 on the opposite side. The profile walls 95, 96 and the profile cover 97 enclose a hollow chamber 98. Both profile walls 95, 96 have an inward-facing bulge 101, 102, in each of which a screw hole 103, 104 is formed. Just above the bulges 101, 102, support struts 105, 106 protrude from the profile walls 95, 96, pointing away from the hollow chamber 98. A dividing web 107 rises perpendicularly from the profiled ceiling 97, with a cover 108 projecting on both sides of the dividing web 107.The cover 108 extends further over the separating strip 107 on one side (facing away from the roof ridge) than on the other. This helps later when inserting the solar module 5, which is then overlapped by the cover 108 in its final position. The separating strip 107 is interspersed with drainage holes 110 along its entire length.

[0041] The Fig. 30 and Fig. 31 shows the spacer 120. This has a bridge-shaped strip 121, which rests on a foot 122, 123 on both sides. From the feet 122, 123, the strip leads with a rising web 124, 125 to a crossbar 126, on which a pin 127 is arranged. The pin 127 is integrally formed on the crossbar 126 and connected to the crossbar 126 by only four tongues 131, 132, 133, 134. The material recesses 135, 136, 137, 138 create predetermined breaking points so that the pin 127 can be separated from the spacer 120 if it is not inserted between two solar panels but at the end of the solar covering.

[0042] The Fig. 31 and Fig. 32 is used to close the front of the insert profile 90. The two holes 141 and 142 are drilled coaxially over the screw holes 103, 104 ( Fig. 27) and penetrated by two system screws 150, which fasten the profile cover 140 to the insert profile 90.

[0043] The Fig. Figures 34 to 38 show the system screw 150. This is used for most system components that require screwing. The only exception is the connection of the profile connector 60 to the base profile 40 using the screw 84. The system screw 150 comprises a shaft 151 with an external thread 152 and a head 153 with an external turning engagement 154 in the shape of a hexagon. A load distribution disc 155 is formed between the head 153 and the shaft 151, with locking teeth 156 applied to its underside. In addition to the external turning engagement 154, the head 153 of the system screw 150 also provides an internal turning engagement 157 in the shape of an internal Torx head.

[0044] The Fig. 39 to 41 show the threaded plate 140. This has a square cross-section and has a central internal thread 141.

[0045] The Fig. 42 to 58 show the individual work steps when using the assembly system 1 according to the invention.

[0046] The Fig. 42 prepared roof hooks 10 are pre-assembled. The support arm 21 is screwed to the mounting bracket 11 by inserting the threaded plate 140 ( Fig. 39, Fig. 1 and Fig. 3) and fixed with the system screw 150. First, the support arm 21 with its grid 26 is positioned on the grid surface 18 of the mounting bracket in such a way as to achieve the distance “b” ( Fig. 1) to an existing counter batten. Use wood screws 8 ( Fig. 1), the mounting bracket 11 is mounted on a roof batten 7. The support arm 21 and the bracket 31 are connected to each other using another system screw 150. Depending on the type of roof covering and the desired distance between the roof covering and the solar element 5, the grid 28 of the support arm 21 is aligned with the grid surface 39 of the bracket 31 with the dimension "a" ( Fig. 1) and fixed with the system screw 150.

[0047] In Fig. 43 shows the mounting grid created with the roof hooks 10 without roof substructure and roof covering.

[0048] The roof hooks 10 are then attached to the prepared mounting grid according to the Fig. 44 and Fig. 45 the base profiles 40 are mounted. For this purpose, the system screw 150 is also used, which is inserted through the slot 47 into the chamber 49 of the base profile 40 and passes through one of the elongated holes 42 in the profile base 41 ( Fig. 17) and into the threaded hole 35 of the boom 31 ( Fig. 32). The assembled situation is also shown in Fig. 46 shown.

[0049] The Fig. 47 in connection with the Fig. 22 and Fig. 25 show the next step. Now, the profile connector 60 is mounted on the base profile 40. The clip 85 is pressed into the base profile. The feet 54, 55 snap behind the lugs 45, 46 of the base profile 40 ( Fig. 16). The lugs 45, 46 of the base profile 40 come to rest in the grooves 56a, 57a of the clip 85. If now the Fig. When the screw 84 shown in Figure 25a is tightened, the pin 84a spreads the feet 54, 55 of the clip 85 and simultaneously slightly raises the clip 85. This optimizes the clamping force between the clip 85 and the base profile 40.

[0050] The assembly of the profile connectors 60 on the base profiles 40 is again carried out according to a specific grid, as shown in the Fig. 48 and Fig. 49. The insert profiles 90 are now attached to the prepared mounting points. For this, a few steps must be observed again, which are described in the Fig. 50 to 51. The insert profiles 90 are aligned transversely to the base profiles 40. The insert profiles 90 are connected to the base profiles 40 using profile connectors 60, which were previously attached to the base profiles 40. No fasteners in the form of screws or the like are required for assembly. The insert profiles 90 are clipped into the profile connectors 60. Fig. Figure 50 shows how the insert profile 90 is inserted, slightly tilted, into the trough 62 of the holder 61 of the profile connector 60. The hook 94 of its connecting base 91 engages the piping 65 of the holder 61. The insert profile 90 is then moved into its horizontal position and, in the process, its strip 93 is pushed past the flange 78 of the clamp 75 of the profile connector 60, which is thereby slightly displaced so that the strip 93 comes to rest under the hook 66 of the holder 61, while the flange 78 springs back to its original position due to its flexurally elastic properties. The insert profile 90 is thus fastened to the profile connector 60 in a wind suction-proof manner. By screwing in the screw 84, the flange 78 is also pressed down onto the strip 93, thus ensuring a wind suction-proof fastening. This situation is also in Fig. 51 shown.

[0051] In the Fig. 52 to 58 are related to the Fig. 1 and Fig. 27 describes the steps for inserting the solar modules 5. First, the solar module 5, which is slightly lifted at the rear or bottom, is inserted with its front side 6 first into the frame 92 of the insertion profile 90, so that its front side 6 rests against the separating web 107. Since this is a pitched roof (in the drawing the situation is shown horizontally), there is a slope, so that the previously Fig. 53 inserted solar module 5, still lying on the separating bar, moves downwards due to gravity (to the right in the picture), which in Fig. 54 through the resulting distance to the separating web 107.

[0052] As in the Fig. 55, the spacers 120 now come into effect, imparting a prestress to the inserted solar modules 5. The bridge-like structure of the spacer 120 compensates for the distance between the separating web 107 and the respective end face of the solar module 5, so that the solar module 5 is securely held. Fig. 55 also shows how the pin 127 of the spacer 120 protrudes between two adjacently inserted solar modules 5 and keeps them at a distance. If the spacer 120 is inserted on the outer solar module 5, the pin 127 can be secured with the aid of the provided material recesses 135 to 138 ( Fig. 31) must be broken off, otherwise it will prevent the profile cover 140 from being screwed on (see Fig. 57). The profile cover 145 is screwed onto the front edge of the insert profile 90 using the system screws 150.
