Description

Support frame for plate-shaped solar cell or solar panel modules

The invention relates to a support frame for plate-shaped solar cell or solar panel modules, with at least two parallel longitudinal members for mounting the modules in a mounting plane.

For the formation of freestanding photovoltaic systems Traggestell known, in which parallel side members are mounted on anchored in the ground stand at a distance from each other. The solar cell modules are placed in juxtaposed arrangement on the side members and fixed thereto by means of hat clamps, so that they are fixed in an inclined relative to the horizontal mounting plane on the support frame. A disadvantage of this prior art device is, among other things, the great installation effort. Furthermore, the solar cell modules are included in the static system in such a way that they must absorb forces so that the given total load can be borne. Especially with additional wind loads or snow loads, there is the danger that hair cracks will form in the solar cells due to the deflection of the modules, which results in a reduction of the module output.

The object of the invention is to provide a support frame of the type mentioned, in which the assembly costs for attaching the modules is substantially reduced. According to the invention, this is achieved by a support frame having the features of claim 1.

In a support frame according to the invention, the modules can be mounted in a very simple manner, preferably completely without screws. After inserting a respective module into the receiving grooves of the two longitudinal members, at least one insert part is inserted at least into the intermediate space between the front side of the module located in the first receiving groove and the bottom of the first receiving groove. This insert part may preferably be a part which is clamped in this intermediate space by a spring-elastic design.

Conveniently, the side members are on cross members and are attached thereto. It can thereby be formed in a rigid support frame with high stability, which can absorb the forces occurring. In this case, the static system is designed independently of the modules and the modules have significantly lower forces, in particular in the case of wind loads and snow loads. Preferably, the cross members are attached to uprights, which in turn are secured to anchored in the ground anchoring parts. In this way, an advantageous freestanding construction (that is not attached to a building) can be formed.

Preferably, the longitudinal members are each formed in one piece.

In a preferred embodiment, the longitudinal members each comprise an upper flange, a lower flange and a gutter formed by at least two individual webs, wherein webs protrude from the intermediate web on both sides and form the lower side limbs of a first and a second receiving groove. The upper side legs of the first and second receiving groove are in this case formed by the respective over the gutter projecting portion of the upper belt and forming the groove bottom, connecting the two side leg connecting web of the respective receiving groove is formed by a portion of the double-walled gutter of the longitudinal member. Such a longitudinal beam can be formed with a relatively low material cost with sufficient stability and it is provided in the area between the lower side legs and the lower flange a space for the passage of cables or other installation elements. Also are not required in differently shaped side members.

Conveniently, the receiving grooves on the two longitudinal sides of the longitudinal member here are formed differently deep, with an advantageous assembly and anchoring of the modules can be achieved.

Further advantages and details of the invention are explained below with reference to the accompanying drawings. In this show:

In the embodiment shown in FIGS., The free-standing support frame comprises three parallel side members 1 (= longitudinal profiles), wherein in each space between two side rails 1, a series of plate-shaped modules 2 is arranged. The modules 2, which are shown only schematically in the figures, can in particular be solar cell modules. The modules 2 can also be solar collector modules.

The longitudinal members 1 are located in the longitudinal direction of the longitudinal members 1 spaced apart and perpendicular to the longitudinal members 1 extending cross members 3 (= cross sections) and are attached thereto. The cross member 3 are fixed by means of gusset plates 4, 5 on stators 8, 9. The uprights 8, 9 are mounted by means of gusset plates 6, 7 to ground anchors, concrete foundations o. The like., Which may be formed in a conventional manner and are not visible in the figures. Between the gussets 6, 5 extend oblique struts 10, whereby a kind of truss structure is formed. For example, all three to seven meters cross member 3 and these supporting parts may be present.

A possible embodiment of the cross member is shown in FIG. 14. The cross members are formed as box-like profiles, wherein the upper wall is thickened and projects laterally beyond the side walls and is formed in this way as a support flange 11 for the longitudinal members 1. On the side walls undercut grooves 12, 13 are arranged for receiving sliding blocks, whereby the connection with the gusset plates 4, 5 can take place. The gusset plates 4 to 7 may be connected in an analogous manner to the uprights 8, 9, which for this purpose also have undercut grooves 14, 15, as shown in FIG. 15 can be seen. The oblique struts 10 may have the same cross-sectional shape as the uprights 8, 9 and be connected in the same way with the gusset plates 5, 6.

Other connections between the cross members 3, the uprights 8, 9 and the oblique struts 10 are conceivable and possible, for example, screw or welded joints.

The longitudinal beams 1 shown in detail in FIGS. 11 and 12 comprise a top flange 16, a bottom flange 17 and a gutter 18 connecting the top flange 16 to the bottom flange 17. The intermediate web 18 is double-walled in the embodiment shown and is formed by two upper flange 16 and 16 the lower flange 17 interconnecting individual webs 19, 20 are formed, each extending continuously in the longitudinal direction of the longitudinal member 1. On opposite sides of the intermediate web 18, a first receiving groove 21 and a second receiving groove 25 are arranged. These longitudinally extending receiving grooves 21, 25 are formed by U-shaped sections of the longitudinal member 1, which comprise an upper side leg 22, 26, a lower side leg 23, 27 and connecting webs 24, 28 connecting the upper and lower side legs. The upper side legs 22,

26 of the receiving grooves 21, 25 are formed by sections of the upper belt 16, which project beyond the intermediate web 18 of the longitudinal member 1 on both sides. The lower side legs 23,

27 of the grooves 21, 25 are on both sides of the gutter 18 from. The connecting webs 24, 28 of the receiving grooves 21, 25 are formed by sections of the two individual webs 19, 20 of the intermediate web 18.

The distance between the individual webs 19, 20 preferably increases, starting from the region in which the lower side legs 23, 27 are arranged on the individual webs 19, 20, to the lower belt 17. The individual webs 19, 20 run in this case to the lower flange 17 initially apart and in turn in turn parallel to each other. Other courses in which the distance of the individual webs 19, 20 increases towards the lower flange 17 are conceivable and possible. By this increase in the distance between the individual webs 19, 20, the stability of the longitudinal member 1 is increased.

Between the individual webs 19, 20 further preferably runs a connecting crosspiece 29, and conveniently in the area in which the lower side legs 23, 27 of the grooves 21, 25 emanating from the individual webs 19, 20. Instead, for stiffening other configurations of extending between the individual webs 19, 20 webs may be present, for example, a Y-shaped web, on the one hand on the lower flange 17, on the other hand on the individual webs 19, 20 is attached (for example, again in the region of the lower side legs 23, 27).

The thicknesses of the upper belt 16 and lower belt 17 are favorably greater than the thicknesses of the individual webs 19, 20, at least in their central regions. The lower belt 17 has the greatest thickness in its middle region in the illustrated embodiment.

The side wall 30 of the first receiving groove 21 formed by the lower side limb 23 has a depression 32 in the region adjoining the bottom 31 of the receiving groove 21. This depression is formed by an obliquely extending portion of the lower side limb 23. Other embodiments of such a recess 32 are conceivable and possible, for example, by a stepped course of the lower side leg 23 or by reducing its wall thickness. By such a recess 32, the insertion of the modules 2 described in more detail between two side members 1 is facilitated.

The modules 2 are mounted on the longitudinal members 1 in a mounting plane 33, which is inclined to the horizontal. The side members 1 lie with their lower chords 17 on the support flanges 11 of the cross member 3 and are attached thereto. A particularly advantageous type This attachment consists in a bond. In this case, preferably, a horizontal, double-sided adhesive tape is attached to the support flanges 11 of the cross member 3 initially in a region in which a lower lying in the assembled state portion of the lower belt 17 is to come to rest. In the region of the support flange 11, which is higher than the adhesive tape and in which a higher lying in the assembled state portion of the lower belt 17 comes to rest, an adhesive, preferably a silicone adhesive is applied. The longitudinal member is aligned and placed on the support flange 11. By the pre-applied double-sided adhesive tape in this case the alignment of the longitudinal support is facilitated and a swelling of adhesive down is prevented. Also results from the double-sided tape a good initial adhesion.

Other connections of the longitudinal members 1 with the cross members 3 are conceivable and possible, for example via clamping connections, screw or welded joints.

The longitudinal members 1 are aligned such that of two longitudinal beams 1, between which a series of adjacent modules 2 is to be mounted, the first receiving groove 21 has obliquely downwards at the higher longitudinal member 1 and the second receiving groove 25 obliquely upward at the lower longitudinal member 1. The reverse orientation of the longitudinal members 1 (in the higher longitudinal member, the second receiving groove 25 obliquely down and the lower longitudinal member, the first receiving groove 21 obliquely upward) is conceivable and possible, but less preferred.

To insert a module 2 between two adjacent side members 1, the module 2 is first tilted about an imaginary axis 34 parallel to the longitudinal members 1 with respect to the mounting plane 33, as shown in Fig. 5. In this orientation, the higher side member 1 facing, parallel to the side member 1 extending end face 35 is inserted into the first receiving groove 21 of this higher-lying longitudinal member 1, and indeed deeper than in the finished assembled state of the module 2 is the case in particular, the end face 35th are introduced into the first receiving groove 21 until it abuts the bottom 31 of the first receiving groove 21. The recess 32 of the side wall 30 of the lower side leg 23 of the first receiving groove 21 in this case forms an exemption for insertion of the peripheral portion of the module 2 in its tilted position. The acting on parts of the longitudinal member 1 during insertion bending load and the game in the inserted state is thereby reduced. Preferably, the edge-side portion of the module 2 is in the inserted state without play between the side legs 22, 23 of the first receiving groove 21st

In this state, the module 2 is pivoted about the imaginary axis 34, which passes through the module 2 in the region of the end face 35 in the mounting plane 33 Here comes to the lower side member 1 facing end face 36 subsequent portion of the module 2 to rest on the lower side leg 27 of the second receiving groove 25 of the lower longitudinal member 1. This state is shown in Fig. 6. As a result, the end face 36 is inserted into the second receiving groove 25 until the position shown in Fig. 7 is reached. In this position, the end face 36 wins in the illustrated embodiment at the bottom 47 of the second receiving groove 25 at. The edge portion of the module 2 may preferably be arranged without play in the second receiving groove 25.

In order to prevent or limit a displacement of the module 2 in its plane (= in the mounting plane 33) perpendicular to the longitudinal members 1 after inserting a respective module 2, the modules 2 are inserted into the intermediate spaces between the end faces 35 located in the first receiving grooves 21 and the bottom 31 of the first receiving groove 21 Einsatztei- Ie 37 used. These serve in the embodiment shown at the same time to form a predetermined gap between two adjacent modules in a row. 2

The insert parts 37 are apparent in particular from FIGS. 9 and 13. These are seen in front view (FIG. 13) formed T-shaped and comprise a spacer leg 38 and at one end of the spacer leg 38 on both sides of this projecting T-leg 39. At the free ends of the T-leg of both sides of the spacer leg 38 are resilient Kiemmflügel 40 arranged, which extend starting from the respective free end of the T-leg 39 arcuately in the direction of the spacer leg 38. A rectilinear oblique course of the clamping wings 40 would also be conceivable and possible, for example. The resilient deflection of the clamping wings 40 in the direction of the T-leg 39 is limited by protruding from the T-leg. 39 stop webs 41.

After a respective module 2 has been threaded between the two side members 1, on the side of the module 2 on which the next module 2 of this series is to be inserted, an insert 37 with one side of its T-leg and the clamping wing 40 attached thereto pressed into the space between the end face 35 and the bottom 31 of the first receiving groove 21 until the spacer leg 38 abuts the perpendicular to the longitudinal members 1 extending end face 42 of the module 2, as shown in Fig. 9.

After the next module 2 has been threaded in the manner described between the side members 1, wherein it is further spaced from the previous module as in the final state (this state is shown in Fig. 9), this next module 2 in the receiving grooves 21, 25 parallel to the longitudinal beams 1 in the direction of the previously attached module 2, wherein the other side of the T-leg 39 of the insert member 37 and attached thereto clamping wing 40 in the space between the end face 35 of this next module 2 and the bottom 31 of the first Receiving groove 21 is inserted until the end face 43 of this next module 2 rests on the spacer leg 38 (see Fig .. 8).

This assembly process is repeated until all modules 2 are mounted. To the outside. ing edges 42, 43 of the peripheral modules 2 of a respective row are also inserted inserts 37 between the end faces 35 and the bottom 31 of the first receiving groove 21. The projecting on the other side of the spacer leg 38 T-leg 39 can be canceled in the sequence at a predetermined breaking point 44. To form cable ducts between a respective lower side limb 23, 27 and the lower chord 17, cable clamps 45 with slots 46 (cf., Figures 16 and 17) may be slipped onto the lower chords 17, as shown in Figure 10 (prior to sticking a respective longitudinal member 1 on the support flanges 1 1 of the cross member 3). Also Rastverbindun-- gene for cable clamps to form cable channels are, for example, conceivable and possible.

The cables themselves are not illustrated in the figures for the sake of simplicity.

The side members were previously described as "double belt carrier" with a top flange 16, a bottom flange 17 and an intermediate web 18 extending therebetween and webs 23, 27 extending from both sides on this intermediate web. Instead, this side rail could also be considered as a box section, wherein on the side walls of the box at least upper and lower side legs 22, 26; 23, 27 protrude and preferably has the lower side wall protruding extensions on both sides and, where appropriate, a lateral web connecting the side walls in a central region 29 is present.

The length I _{1 of} the upper side leg 26 of the second receiving groove 25 is smaller than the difference d (FIG. 4) between the distance A of the bottoms 31, 47 of the first and second

Receiving groove 21, 25 and the perpendicular to the longitudinal extent of the longitudinal beams 1 measured length L of the modules 2. The length I _{2 of} the lower side leg 27 of the second receiving groove 25, however, is preferably greater than this difference d to a support for the modules 2 when threading between to provide the two side members 1. The lengths ITi ₁ , m _{2 of} the upper and lower side limbs 22, 23 of the first receiving groove 21 are greater than this difference d, so that in the threaded and moved to the bottom of the second receiving groove 25 state of the end face 36 of the module 2 a subsequent to the end face 35 Section of the module 2 in the first receiving groove 21 remains.

In principle, it would also be conceivable and possible to also use an insert part between the end face 36 of the module 2 and the bottom 47 of the second receiving groove 25. The lengths ITi ₁ , ITi _{2 of} the upper and lower side limbs 22, 23 of the first receiving groove 21 could then also be smaller than the difference d, but in the inserted between two side members 1 state of a module 2 to the end faces 35, 36 adjoining edge portions of Module 2 should still be within the grooves 21, 25.

Various further modifications of the embodiment shown are conceivable and possible without departing from the scope of the invention. For example, instead of having three side rails, only two side rails (for a single row of modules) or more than two side rails (for more than two rows of modules) could be present. It would also be conceivable and possible for the highest longitudinal member to have a receiving groove only on the side facing downwards and the lowermost longitudinal member only on the side facing upwards. Also, all side members could only have one single take-up at a time. menut (which is respectively formed as the first or second receiving groove), wherein for a respective row of modules in each case two longitudinal members would be provided with mutually facing first and second grooves.

The first and second receiving grooves 21, 25 could also be formed in a different manner than shown, but a spaced from the lower flange 17 of the longitudinal member 1 arrangement is preferred. In principle conceivable and possible, it would also be the gutter 18 of the longitudinal member only form single-walled, but this is less preferred.

Also for the inserts 37 are various other training options, which in principle also bolted to the side rail 1, glued or otherwise fixed spacer blocks conceivable and possible without resilient elements. A resilient loading of the protruding into the first receiving groove 21 end face 35 of the module 2 by the insert member 37 is preferred. Even if the spacing of modules 2 following one another in a row is preferred by the insert parts 37, such a spacing through the insert parts 37 could also be dispensed with.

Anti-theft protection can also be achieved by the insert parts 37 (the edge-side modules still have to be secured separately against being pushed out in the longitudinal direction).

Figs. 18 to 19 show a slightly modified embodiment of the side member to allow easy longitudinal connection of two side rails. On the mutually facing inner sides of the individual webs 19, 20 are on the one hand at the same distance from the lower flange 17, on the other hand at the same distance from the upper flange 16 each strip-like projections 48 to 51 arranged between the lower flange 17 and the projections 48, 49, a first forming tube 52, which has a rectangular cross-section, are inserted in the longitudinal direction of the longitudinal member 1. Between the upper flange 16 and the projections 50, 51, a second forming tube 53, which has a rectangular cross-section, can be inserted in the longitudinal direction of the longitudinal carrier 1. On the partially inserted into a side rail 1 forming tubes 52, 53 (as shown in Fig. 19), now a second side rail can be pushed, wherein the forming tubes 52, 53 are inserted into the corresponding spaces of this second longitudinal member 1. As a result, the forming tubes 52, 53 can be connected to the longitudinal members 1, for example by introducing bores and inserting rivets. Other attachment possibilities of the molding tubes 52, 53 on the longitudinal members 1 would be adhesive, screw or pin connections. L egende to the reference numbers:
