Description

The invention relates to a Dachsolarmodulbefestigungssystem for attachment of roof modules arranged on a roof with a number of carrier rails, are placed on the roof modules.

Photovoltaic roof modules, hereafter referred to simply as PV modules, can be mounted in three fundamentally different roof constructions: In an in-roof construction, the PV modules are used as roof-covering elements, so that they replace roof tiles, shingles or the like. In an on-roof construction, the PV modules are placed on top of an existing roof so that they cover the existing roof. In so-called open-land constructions, the PV modules together with the supporting system holding them themselves form the roof and are not additionally placed on a roof or in a roof construction. Outdoor constructions are also suitable as a roof for simple buildings, such as sheds and carports.

For installation, PV modules are incorporated into a roof-mounted solar module mounting system and securely fastened there so that they do not come loose in a storm, for example.

It is an object of the present invention to provide a roof solar module mounting system with which roof modules can be easily, quickly and securely fastened.

This object is achieved by a Dachsolarmodulbefestigungssystem of the aforementioned type, which according to the invention comprises a clamping means for clamping holding a roof module on a support rail. The roof modules can be easily mounted and securely clamped on at least one of the support rails.

A roof module is expediently a roof covering element and may be a PV module, a thermal solar module for heating liquid, a roof window or another module. The roof may be a pitched roof, with the roof modules being scaled, ie partially superimposed, so that running water falls from the bottom edge of an overhead module to the underlying one. It is also possible that the roof modules abut each other so that there is no oversupply.

The support rails can be aligned in the direction of flow, ie in the direction of the strongest roof pitch, and constructions are conceivable in which they are aligned perpendicular thereto. They have expediently an upper side or a side facing the roof module for direct or indirect support of the roof module on it. The support rail may be a rail, z. As a metal rail, with aluminum has proved to be particularly advantageous.

The Dachsolarmodulbefestigungssystem is advantageously constructed so that it forms a roof together with the roof modules, so it carries the roof modules, the support elements and the roof modules thus form the roof without another subframe of a roof structure. Advantageously, the carrier rails during installation of the roof modules on it and in particular after the completion of the roof from below accessible. The roof solar module mounting system is preferably a system for outdoor construction, which also includes roof structures for a simple building, such as a shed or a carport, in which the roof solar module mounting system forms the supporting roof structure.

In an advantageous embodiment of the invention, the clamping means engages positively in a recess of the carrier rail and extends together with a holding means for locking the clamping means in clamping position completely through the carrier rail therethrough. The holding means can be connected to the support rail on the back or underside of the support rail, ie on the side facing away from the roof module, for example, be screwed to this, whereby a stable and easy-to-install attachment of the roof module is achieved on the support rail.

The clamping means serves for the indirect or immediate clamping holding a roof module on a support rail. It extends together with the holding means from top to bottom through the support rail, wherein the holding means advantageously engages behind the support rail for locking the clamping means below. To lock it is conveniently visible and operable from below. However, it does not have to extend to the lowest point of the carrier rail, but can extend into a recess accessible from below. Advantageously, the clamping means is designed so that it is prepared for clamping holding two adjacent roof modules.

The holding means can be made in one piece with the clamping means or separately thereto, wherein it then advantageously cooperates positively after assembly with the clamping means. If the holding means projects through a recess, for example a hole, out of the underside of the carrier rail facing away from the roof module, then it can simply be fastened to the carrier rail and the roof module can be easily mounted. The lower end of the holding means may be arranged in a profile recess in the underside of the carrier rail, it being advantageous if it can be operated from below, clamped, screwed or the like. A profile recess may be a depression in the profile, which is produced by the profile cross-section, that extends along the entire profile. The holding means may be a screw or any form, force or cohesively acting fastener. Roof modules can be mounted particularly easily if the holding means is a blind rivet.

In a further advantageous embodiment of the invention, the holding means is a traction means, which pulls the clamping means down on the carrier unit, or is prepared in the unassembled state. As a result, the roof module can be held with a voltage on the support rail, so that a more secure connection between the support rail and roof module is created.

A further embodiment of the invention provides that the holding means protrudes through a lower plate of the support rail and a lower plate of the clamping means and braces both plates together with the roof module clamped. The two plates are thus suitably pulled towards each other, wherein the two plates form an advantageous attack and holding surface for the holding means.

A uniform over the length of the roof module clamping force can be applied to the roof module when the clamping means is a rail. Conveniently, the clamping means is connected to a plurality of holding means, which extend completely through the carrier rail, so that the clamping means can be rigidly fixed at several points with the support rail and expediently clamped with it.

The clamping means engages positively in a recess of the carrier rail. This recess of the carrier rail is advantageously an upwardly open and U-shaped recess, ie with two mutually parallel walls. As a result, the clamping means can be inserted from above into the recess. The recess is expediently a profile recess, so it extends through the entire length of the carrier rail. By the U-shape, the holding means can always be performed safely at different depths of the recess, whereby a simple mounting of the clamping means in the carrier rail can be achieved.

The invention is also directed to a method of mounting a roof module on a support rail of a roof solar module mounting system. It is proposed that a clamping means inserted into a recess of the support rail, the roof module is placed on the support rail and pushed under the clamping means and the clamping means is pulled by means of a holding means from below into the recess, so that the roof module is clamped on the support rail , Conveniently, the clamping means is first inserted into a recess of the support rail and then the roof module indirectly or directly placed on the support rail. Subsequently, the roof module can be inserted under an overlap, which expediently has the clamping means, so that the roof module is overlapped by the clamping means. Here, the roof module can abut the side of the clamping means. Subsequently, the clamping means can be pulled from below by means of the holding means in the recess, so that the roof module is clamped on the support rail.

When the roof module is clamped in, the clamping means expediently has a clearance downwards of at least 1 mm in the recess. This allows a reliable clamping of the roof module can be achieved on the support rail.

For good guidance of the clamping means in the support rail, it is advantageous if the clamping means in the recess of the support rail has a thickening and the side of the thickening on both sides of the wall of the recess of the support rail, advantageously on both sides flat, so that an outer surface of the thickening area on a Inside the recess is applied, with a game is referred to 1 mm as concerns.

If the clamping means engaged in the recess of the carrier rail or latched before mounting designed with the carrier rail, the clamping means can be particularly easily mounted in the carrier rail. With the same advantage, the clamping means can be dimensioned in its dimensions so that it is frictionally inserted in the recess of the carrier rail, so that the clamping means alone holds its position and does not fall into the recess further. For this purpose, the clamping means may have a small shape or the carrier rail in the recess a small inwardly directed formation, which holds the clamping means in the recess in the position in which it was inserted.

A further advantageous embodiment of the invention provides that the clamping means projects into the recess of the carrier rail with a bracket into which the holding means engages. Also, the bracket is advantageously a profile element, so extends over the entire length of the clamping means. The retaining means can engage behind the bracket, either inserted laterally or through an opening of the bracket.

It is also proposed that the carrier rail has a profile recess on its underside and the holding means engages through the carrier rail in the recess. The profile recess extends along the entire length of the carrier rail and may have a flattened V-shape, in the flattening of the holding means is arranged. The end of the holding means advantageously remains in the recess and does not extend down beyond the carrier rail.

Especially with non-scaled arranged roof modules, the task is to seal the composite of the roof modules so that the composite forms a sealing roof. Here, the seal should be as easy to assemble and done with simple means.

To solve this problem it is proposed that the carrier rail has a Wasserabführrinne and the clamping means comprises a water absorber, which initiates along the clamping means running water in the Wasserabführrinne. In this way, water running between roof modules can be routed via the water drainage into the water discharge channel, where it drains off and can be led to a desired location, so that the composite of roof modules can already assume a sealing roof function. This solution is particularly suitable for open-air structures or open roofs, z. B. of carports, scales or the like.

A water drain can be made particularly efficient if the support rail has two Wasserabführrinnen symmetrically arranged to each other and the clamping means two symmetrically arranged to each other and water discharge, each of the clamping means along running water into one of the Wasserabführrinnen.

If the water collectors form a saddle roof structure together, a simple and reliable discharge of water into the water discharge channels can be ensured. The water arresters form a saddle roof structure, in particular, when they are oblique to the vertical and horizontal and in particular to the profile center of the clamping means are designed as mutually symmetrical surfaces.

When mounting roof modules on a pitched roof or slanted support rails, it may happen that a previously placed on a support rail roof module slips down before it was fixed, so that the installation of this and other roof modules is obstructed.

This problem can be solved in that the carrier rail has a shape that engages behind a roof module at one of its lower edges such that it is held positively in the direction of flow. The roof module to be mounted can be placed on the carrier rail, the shaping engages behind the roof module and thus holds it in a desired position.

Conveniently, the molding is an elastic locking means which is pressed by the roof module in a tensioned position and engages elastically behind the lower edge in a movement of the lower edge of the roof module via the locking means. The roof module can be pushed over the locking means until the lower edge reaches the locking means. The locking means snaps behind the lower edge and holds the roof module in position.

The molding can be made particularly simple and inexpensive if the support rail is an extruded profile and the formation is a bent out of the extruded profile molding.

If the form-fit occurs along the longitudinal direction of the carrier rail, the module can be prevented from slipping in the longitudinal direction of the carrier rail, so that it does not slip in the direction of flow and thus down.

In order to achieve a secure holding the latched roof modules, it is advantageous if the molding is an elastic latching means and the clamping means compresses the latching means in the mounted state of a roof module against its latching function. The locking can even be canceled, so that the roof module taut on the support rail. In this case, an adjacent roof module lie on molding and press down the molding.

The invention will be explained in more detail with reference to exemplary embodiments, which are illustrated in the drawing.

Show it:

1 a section of a roof with a plurality of roof modules, which are held by a roof solar module mounting system,

2 two roof modules, which are held by a clamping means on a support rail in a sectional view,

3 a clamping means which is locked in a carrier rail.

5 another carrier rail with latching webs,

6 the carrier rail off 5 with a molded locking means under a roof module and

7 the locking means 6 which is pressed down from an adjacent roof module.

1 shows a section of a pitched roof 2 with a roof pitch of, for example, 30 °. The pitched roof 2 is with a variety of roof modules 4 . 6 of which, for the sake of clarity, only four roof modules 4 . 6 are shown. There are two types of roof modules 4 . 6 shown, with the roof modules 4 PV modules are and the roof module 6 another roof module, such as a roof window, a thermosol solar panel, or a regular roofing panel without solar function. The PV modules 4 are glass modules for the photovoltaic generation of electricity.

The roof modules 4 . 6 are supported by a roof solar module mounting system 8th with • a number of carrier rails 10 in the flow direction 12 and are arranged transversely thereto and forming a crossbar assembly forming interconnected. The carrier rails 10 , of which only in the flow direction 12 are arranged arranged, carry the pitched roof 2 static, so the roof solar module mounting system 8th with the roof modules 4 . 6 the pitched roof 2 forms.

The roof modules 4 . 6 are arranged in an overlapping manner, so that a lower edge 14 an upper roof module 4 . 6 a piece wide an upper portion of an underlying roof module 4 . 6 over covers, so its top edge 16 below the respective roof module above 4 . 6 to come to rest. In this way, the roof modules 4 . 6 as the pitched roof 2 forming and sealing elements of a roofing performed analogous to conventional roofing systems. The pitched roof 2 is part of a carport and protects a surface below it from rain. The carrier rails 10 are at least largely accessible from below.

2 shows a carrier rail 10 the roof solar module mounting system 8th out 1 in a sectional view in the flow direction 12 , The carrier rail 10 is an extruded aluminum profile, which is formed mirror-symmetrically to a longitudinal center plane. On top of it 18 lie two roof modules 4 immediately on. The roof modules 4 are PV modules, with a photovoltaic glass element 20 in a metallic frame 22 is caught. To increase the rigidity of the roof module 4 is between the frame 22 and the glass element 20 a cavity 24 with a depth of about 35 mm from top to bottom, so the roof module 4 has a total thickness of about 40 mm.

The roof module 4 lies with its frame 22 immediately on top 18 the carrier rail 10 on and off by a clamping means 26 clamping on this top 18 held. The clamping means 26 is also a extruded or extruded one-piece rail made of plastic or metal, in particular aluminum. It is with a jetty 28 equipped, at the top of a T-shaped roof 30 is formed on both sides of the bridge 28 protrudes, each with a half roof of the roof modules 4 partially overlaps. The roof modules 4 lie with their side surface flat on the bridge 28 so that a compact composite of roof module 4 , Footbridge 28 and again roof module 4 arises.

At the bottom of the dock 28 is a strap 32 molded in the manner of a stirrup, but according to the extruded profile, the entire length of the clamping means 26 the same shape. The coat hanger 32 has a side surface on both sides 34 , each flat on an inner surface 36 the carrier rail 10 issue. The dimension of the clamping device 26 and a U-shaped recess 38 the support rail are such that side surfaces 34 of the clamping means 26 frictionally engaged with inner surfaces 36 the recess 38 of the carrier rail 10 are connected, so that the clamping means 26 Although expediently easily slipped, but still so tight in the recess 38 it is not held by itself in the recess 38 falls into it.

In the bottom of the clamping device 26 is an opening 40 introduced, for example in the form of a bore. Alternatively, the opening 40 be a continuous profile opening, so that can be dispensed with holes. Also in a bottom 42 the carrier rail 10 is an opening 44 brought in with the opening 40 flees. Also the opening 44 may be a hole. In these two aligned openings 40 . 44 is a holding agent 46 positioned in the in 2 a blind rivet shown, which is shown somewhat in perspective for the sake of clarity, however, in the 2 shown cutting plane is therefore in the paper plane. The clamping means 26 goes together with the holding means 46 completely from top to bottom through the carrier rail 10 therethrough.

By the holding means 46 , which may alternatively be a self-tapping screw or an equivalent acting means, may be the clamping means 26 With the bottom 42 be positively connected, expediently by the holding means 46 the clamping means 26 down to the bottom 42 draws. In the case of a rivet, this is very easy to do by the blind rivets is tightened so that the head 48 the blind rivets the clamping means 26 down towards the bottom 42 draws. In the case of a selbstscheidenden screw would be the opening 44 slightly larger than the opening 40 so that the tightened screw is the clamping means 26 also pulls down. The train transfers over the jetty 28 on the roof 30 that the two roof modules 4 down to the top 18 the carrier rail 10 presses and thus safely on the support rail 10 holds. The bottom 42 can be designed in the form of a lower plate. Also the clamping means 26 has a lower plate 43 on. Both sub-plates 42 . 43 , which expediently parallel to each other and in particular perpendicular to the pulling direction of the holding means 46 run, are braced together.

In order to produce sufficient rigidity, the support rail has 10 a sufficient tread depth 50 on, in the illustrated embodiment, for example, 60 mm. The high tread depth 50 is advantageous for the carrier rails 10 of the pitched roof 2 form a self-supporting umbrella organization, the roof modules 4 . 6 wears without, for example, needing a rafter scaffolding. This tread depth 50 However, it does not have to be present over the entire width of the profile but can be reduced, especially in the middle of the profile. This creates a profile recess 52 - that would be - the carrier rail 10 turn 180 ° upside down - forming an elongated sink. In this profile recess 52 is the lower end of the holding means 46 arranged so that its lower end advantageously completely in the profile recess 52 is safe and not on the tread depth 50 stands out. In addition, a distance 54 between the underside of the clamping means 26 and the bottom 42 the carrier rail 10 be reduced, so that the length of the holding means 46 or the clamping means 26 does not have to be carried out as long, which can save material. In addition, through the profile recess 52 also material of the carrier rail 10 be saved without significantly reducing their rigidity.

The distance 54 However, it should be chosen so that it does not fall below 1 mm, in order to leave enough room for tensioning the clamping device 26 in the recess 38 to ensure. In the embodiment shown, the distance 54 8 mm, which achieves the additional advantage that even 5 mm thinner roof modules 4 . 6 can be attached. This would be the distance 54 be reduced by the corresponding smaller thickness, in the exemplary embodiment by 5 mm to 3 mm, so that without changing the clamping means 26 and the carrier rail 10 different thickness roof modules 4 . 6 on the carrier rail 10 can be attached.

For mounting the roof modules 4 . 6 on the carrier rail 10 First, the clamping means 26 into the recess 38 the carrier rail 10 inserted. The clamping means 26 This expediently only pushed in so far that the roof modules 4 . 6 under the roof on both sides 30 of the clamping means 26 can be inserted, conveniently directly to the bridge 28 , After inserting the roof modules 4 . 6 can the clamping means 26 pushed down, leaving the roof 30 directly on the roof modules 4 . 6 rests.

Is the opening 40 designed as a bore, so is an alignment of the openings 40 . 44 necessary. The longitudinal alignment of the clamping means 26 with the carrier rail 10 and thus the alignment of the openings 40 . 44 can be simplified by the fact that the clamping means 26 and the carrier rail 10 are executed the same length. As a result, the clamping means 26 parallel on both sides with the carrier rail 10 finally in the recess 38 be positioned so that thereby the two openings 40 . 44 lying in alignment on top of each other. Alternatively, the clamping means 26 only at one longitudinal end in alignment with the carrier rail 10 be arranged so that the two openings 40 . 44 cursing one above the other.

In the aligned openings 40 . 44 Now, the holding means can be inserted from below, for example screwed or inserted in the case of blind rivets and tightened. Alternatively, a shape of the clamping means 26 from above through the opening 44 the bottom 42 reach through and so the connection between clamping means 26 and support rail 10 produce. It would also be possible to lock the shape of the clamping means 26 in or under the bottom 42 , a bayonet lock for locking the clamping means 26 on the bottom 42 or a similar element.

In 3 is an alternative clamping device 56 in an alternative carrier rail 58 shown. The following description is essentially limited to the differences from the exemplary embodiment in FIGS 1 and 2 which is referred to for consistent features and functions. Substantially identical components are generally numbered with the same reference numerals and features not mentioned are taken over in the following embodiment, without being described again. This also applies to the in the 4 to 7 illustrated further embodiments.

In contrast to the carrier rail 10 has the carrier rail 58 in the recess 38 latching recesses 60 on, in the corresponding Rastausformungen 62 of the clamping means 56 intervention. In this way, the clamping means 56 from above into the recess 38 inserted and locked there in several stages, the step steps depending on the period length of the latching formations 60 . 62 depends. A positive connection against withdrawal of the clamping means 56 from the carrier rail 58 thus takes place by locking, which locking in addition to the positive connection by means of the holding means 46 or alternatively may be performed. In a very fine Rastausformung 60 . 62 This can also be used to hold the clamping means 56 in the recess 38 used before the clamping means 56 through the holding means 46 is pulled down so that when making the support rail 58 - On the frictional connection can because of the slightly positive connection by the Rastausformungen 60 . 62 be waived - no such high manufacturing requirements in terms of manufacturing tolerances must be made.

4 shows a section of an alternative roof solar module mounting system with another support rail 64 and another clamping means 66 , The carrier rail 64 and the clamping means 66 are arranged in the direction of drainage of the saddle roof. The top of the stirrup 32 of the clamping means 66 is with two water diversion 68 provided with respect to each other with respect to a longitudinally extending symmetry surface of the clamping means 66 symmetrically opposite and together form a saddle roof.

Water, between the two of the clamping means 66 held roof modules 4 runs through it, runs down a drain 68 and from this into a water drainage channel 70 the carrier rail 64 directed. Accordingly, the support rail 64 for every water drain 68 a water drainage channel 70 on that under the associated water drain 68 lies. Water is dripping from the drain 68 into the water drainage channel 70 and is directed by this down, z. B. to another carrier rail 64 or to a gutter or other suitable element. As the water drain 68 over the entire length of the clamping means 66 and the drainage channels 70 extend over the entire length of the carrier rail, can with such carrier rails 64 and clamping means 66 the roof will be completely sealed.

Another carrier rail 72 is in the 5 . 6 and 7 shown. The carrier rail 72 is on her the roof modules 4 facing side provided with web-like lateral extensions, the Rastmittelstege 74 form.

The carrier rails 72 are in the 6 and 7 shown from the side. They run in the drain direction of the saddle roof with a roof pitch of 25 °. To simplify the installation of the roof modules 4 are in the Rastmittelstege 74 each two mutually parallel and 5 mm to 50 mm apart incisions introduced, extending from the outer edge 76 to the vertical profile section 78 extend. The piece between the cuts lying Rastmittelsteg 74 is bent slightly upwards, z. B. with a pair of pliers, and forms a molding 80 up. This formation forms a locking means which is elastically movable up and down.

For mounting the roof modules 4 First, the overhead roof module 4 on the carrier rails 72 pushed up until it's the shape 80 reached. The shape 80 is with its lower end slightly below the beginning of the lower part of the Rastmittelstegs 74 arranged so that the roof module pushed upwards 4 on the shape 80 can slide without touching its bottom edge. This will scratch the roof module 4 avoided.

Subsequently, the roof module 4 pushed further upwards. With its weight, it presses the shape at least a little way down. Reached a bottom edge 82 of the roof module 4 the upper edge of the molding 80 , so the shape snaps up and locked so with the bottom edge 82 of the roof module 4 and forms a positive connection in the flow direction. The roof module is now at the formation 80 and can not slide down again.

To scratch the roof module 4 Even when it is pushed upwards during assembly and pushed back down, is the shaping 80 in the longitudinal direction of the carrier rail 72 Wavy shaped, so that its top edge is slightly down to the latching web 74 has. Thus, the top edge of the roof module 4 while sliding the roof module 4 about the shape 80 do not touch but always stay away from it. Only when the shape behind the lower edge 82 of the roof module 4 engages the upper edge of the molding touches the lower side surface of the roof module 4 , The roof module 4 is now held for the time being and can then be fastened, z. B. by the clamping means 26 . 56 . 66 ,

Subsequently, the adjacent lower roof module 4 on the carrier rails 72 pushed up, as in 6 indicated by the arrow. Its upper lower edge reaches the molding 80 without touching its lower edge, continues to slide and on the molding 80 up and pushes them down, in whole or in part. The shape 80 can lose its holding function, which is not a disadvantage, since the upper roof module 4 now from the roof module below 4 is held in position - if the upper roof module 4 not already attached differently.

Alternatively, the roof modules 4 stay a little bit apart, z. B. to reduce a wind attack force from below into the roof. On a rain seal is then waived. The shape 80 retains its effect and holds the upper roof module 4 in place, with the lower roof module 4 not quite to the shape 80 , is pushed to the shape zoom or only partially. In this way, slots remain between the modules in the direction of travel 4 , Conveniently, the formations 80 in their extent, z. B. between the cuts, so that they specify the desired slot width, so that the lower roof module 4 to the shape 80 can be pushed on. As a result, an exact installation can be facilitated. For this it is advantageous if the molding 80 forms a stop down, so its lower edge over the locking means web 74 protrudes. To scratch the upper roof module 4 To avoid, the formation may be bent downwards at both ends, in particular also on the outer edge 76 ,

Subsequently, the clamping means 26 . 56 . 66 be mounted and tightened so that the two roof modules 4 firmly on the carrier rail 72 be pressed. The shape 80 In this case, it is pushed completely downwards so that it covers the rest of the locking means 74 no longer towering above. It thus completely loses its holding function, now from the clamping means 26 . 56 . 66 is taken over.

The in the 1 to 7 shown details are shown only for the sake of clarity in various embodiments. It is also possible to combine all or any combination of the details shown in a single embodiment.
