Description

DEVICE FOR FIXING PHOTOVOLTAIC PANELS ON A FRAME, FRAME AND DEVICE FOR INTEGRATION OF ASSOCIATED PHOTOVOLTAIC PANELS

The present invention relates to the field of photovoltaic panels of the IAB type (acronym for the expression " Building Integration ", namely photovoltaic panel systems in which the photovoltaic element assumes, in addition to the function of electricity production, the role of a construction element, such as a roof or an awning for example.

The invention relates in particular to a device for adjusting the width of a frame intended to receive and to fix a photovoltaic panel on a frame. It also relates to a frame and an integration device for associated photovoltaic panels.

The invention advantageously makes it possible to adapt the width of the frame in situ to all the dimensions of photovoltaic panels.

Prior art

As part of the energy transition, one of the main challenges is to reduce the share of fossil fuels and increase the share of renewable energies in the energy mix. To do this, incentive measures have been put in place to encourage the deployment of photovoltaic panels in buildings.

To this end, there is a first category of systems making it possible to fix a posteriori , on a finished roof, photovoltaic panels.

Unlike this first category, systems including type IAB photovoltaic panels are placed directly on a frame, for example the frame of a roof, so as to be integrated directly into the roof covering. The structure combined with the photovoltaic panels therefore forms all or part of the roof, and must therefore ensure its main function, namely guaranteeing good sealing or at least reducing the risk of water infiltration into the building.

To do this, document DE-20 2005 015455 has, for example, proposed a technical solution consisting of sealing between the photovoltaic panels and the framework of the roof by means of a membrane covering the upper face of the roof. underlying flat plates. However, the actual panels are themselves fixed at the level of sections secured for example to the framework, by means of screws or nails passing through and therefore perforating said membrane, so that sealing is not guaranteed. Moreover, this solution requires the prior installation of such a membrane, inducing in fact an additional loss of time, increasing the overall costs.

To overcome these drawbacks, document EP 2 395 562 proposes a device for integrating photovoltaic panels on a frame including a plurality of frames, and in particular one-piece frames of standardized dimensions complementary to the dimensions of the photovoltaic panels. The frames are formed by two longitudinal sections of fixed size intended to be arranged in the slope of the roof and two transverse sections, also of fixed size. This frame is in particular capable of receiving the lateral edges of a photovoltaic panel, and it is provided with gutters or projecting elements arranged so as to limit the infiltration of water into the building. However, the size of the sections being fixed, this type of system cannot be adapted in situ to all the dimensions of photovoltaic panels.

Indeed, there are no standards defining a standardized size of photovoltaic panels. The dimensions vary according to the needs and the manufacturers. For example, the photovoltaic panels conventionally found on the market have dimensions that vary within a range of 1.5 to 2 meters in length by 0.8 to 1.1 meters in width. But it is also possible to find custom photovoltaic panels, for example square or very elongated.

Thus, the system proposed by document EP 2 395 562 requires prior knowledge, when cutting the profiles, of the dimensions of the photovoltaic panels. This system therefore has a lack of adaptability which can cause additional costs and installation delays in the event that the cutout is not adapted to the format of the photovoltaic panels.

Thus, the problem that the invention proposes to solve is to develop a device for integrating photovoltaic panels on a frame making it possible, on the one hand, to guarantee the tightness of the structure and, on the other hand , to adapt the device to different dimensions of photovoltaic panels.

Description of the invention

To solve this problem, the invention proposes a device for adjusting the width of a frame intended to receive and to fix a photovoltaic panel on a protective frame with an inclined slope, and in particular on the frame of a roof, of an awning, a shade house, said device comprising:
– a profile extending along a longitudinal axis, parallel to one of the sides of the frame, and
– two structural parts mounted on the profile,
the structural parts being capable, independently of one another, of sliding along the longitudinal axis of the profile in order to adjust the width of the frame.

According to the invention, the adjustable width of the frame corresponds to the sides of the frame extending in a direction transverse to that of the slope or crawling of the roof, the awning or the shade.

The adjustment device thus makes it possible to receive and fix photovoltaic panels of variable dimensions. To do this, the structural parts slide along the profile until they correspond to the length of the side of the photovoltaic panel to be installed. The adjustment is therefore continuous and adaptable to all the dimensions between a length corresponding to the length of the profile taken “alone” and a length corresponding to the length of the profile plus part of the lengths of the two structural parts.

In practice, the device makes it possible to fix the photovoltaic panels according to a “portrait” or “landscape” orientation. The device is also very versatile since it makes it possible to receive and fix, on the same structure, several photovoltaic panels of several sizes, provided that the photovoltaic panels of the same column have the same width and that the photovoltaic panels of the same line have the same length.

This particularity makes it possible to optimize the layout of the photovoltaic panels according to the geometry and the exposure of the buildings.

According to a characteristic of the invention, the profile comprises a chute, in particular intended to be arranged plumb with the underside of the photovoltaic panel, and furthermore intended for the recovery of condensate.

Indeed, when the photovoltaic panel is fixed on the frame, its upper face is exposed to the weather. The water therefore tends to run off the photovoltaic panels and to infiltrate at the level of the interstices separating two adjacent panels. The condensate is thus collected in the channel of the profile. This chute forms a reserve that allows water to accumulate and prevents it from infiltrating further into the building.

According to another characteristic, the structural parts comprise a channel able to evacuate the water from the profile out of the adjustment device.

The channel of the structural parts has a shape adapted to, on the one hand, fit and slide on the profile and, on the other hand, receive the water streaming from the profile.

In order to guarantee the effectiveness of the system when the quantity of water is too great in relation to the capacity of the channel, the structural parts advantageously comprise lateral gutters arranged on either side of the channel, intended to evacuate the channel water out of the adjuster.

Thus, if the water level goes above the side walls of the channel, the overflowing water is received in a second compartment of the structural parts corresponding to the gutters. These gutters constitute a second safety perimeter to ensure the tightness of the roof structure.

Advantageously, the channel and/or the side gutters are flared with respect to the longitudinal axis of the profile in order to increase the capacity of the compartments.

Furthermore, in an equally advantageous embodiment, the channel and/or the side gutters are at least partially inclined with respect to the longitudinal axis of the profile so as to allow the evacuation of the water contained in the channel outside adjustment device. This slope makes it possible to impose a direction and a speed on the water to optimize its evacuation out of the device.

In addition, the side walls of the channel may have discontinuities. These discontinuities have a drip function. They thus make it possible to create a barrier to the progression of drops which would stream along the side walls of the device.

Advantageously, the discontinuities can extend to the level of the lower wall of the channel.

According to one embodiment of the invention, the discontinuities can be filled at least in part by means capable of partly absorbing the water so as to improve the drip function of the discontinuities.

In practice, the profile comprises two slides arranged at the level of the side walls of the profile, and the side walls of the channel of the structural parts each comprise a rail capable of sliding in the slides of the profile. It is partly thanks to this principle that the structural parts can slide on the profile in order to adjust the width of the device.

In order to position the adjustment device within the frame, the structural parts further comprise notches capable of cooperating with a side of the frame perpendicular to the adjustment device.

The notches also have a "drip breaker" function in the event that water runs off the lower portion of the structural parts. The notches thus prevent the drops from migrating towards the frame and compromising its watertightness. Once broken, the drops fall back into the structure at the side of the frame perpendicular to the adjuster.

According to another aspect, the invention relates to a frame intended to receive and to fix a photovoltaic panel on a roof, an awning, a shade, said frame comprising:
– two reception chutes intended to be arranged in the direction of the slope of the roof concerned,
– two devices for adjusting the width of the frame as described above, intended to be arranged in a direction transverse to that of the reception chutes and to cooperate with the reception chutes to allow the evacuation of water from the device, And
– Means for fixing the photovoltaic panel to the frame.

In other words, the frame according to the invention is free of any material in its center, and therefore hollow. The sides of its width are of variable dimensions to adapt to the variable dimensions of the photovoltaic panels on the market. This frame is in particular suitable for receiving the side edges of a photovoltaic panel, and it is provided with chutes and gutters and/or gutters arranged in such a way as to reduce the infiltration of water into the building.

To this end, the channel and/or the side gutters of the structural parts at least partially overlap the receiving channel so that the water contained in the channel and/or the side gutters of the structural parts is evacuated into the receiving channel. reception.

In other words, the combination of the central trough of the adjustment device profile, the channel and/or the side troughs of the structural parts and the longitudinal receiving troughs forms a continuous H-shaped channel.

According to another aspect, the invention relates to a device for integrating photovoltaic panels on a frame comprising:
– a plurality of frames as described above,
– means for fixing the frames to the frame, and
– means of joining the executives together,
the reception chutes being shared by two adjacent frames in the transverse direction of the slope of the roof, and the adjustment devices being shared by two adjacent frames in the direction of the slope of the roof,
the receiving chutes of two frames being adjacent in the direction of the slope of the roof, interlocking or partially overlapping in order to allow the evacuation of water from the device.

Preferably, the free side edges of the receiving chutes of each frame are dimensioned so as to allow overlapping from above. The top overlap corresponds to the overlapping of the free lateral edge of the reception chute of a first frame, by the free lateral edge of the reception chute of another frame, located directly above the first frame, in the direction of the slope of the roof, like tiles.

This ability to cover the reception trunking of adjacent frames ensures sealing without necessarily implementing connection joints. This is an important element in terms of saving time during installation, and consequently in terms of reducing the associated costs.

According to the invention, the means for fixing the frames to the frame comprise, for example, a set of securing parts and screws capable of cooperating with through-holes or machining operations carried out in the securing parts. The use of these connection pieces makes it possible to avoid creating openings in the reception trunking, which would risk compromising the tightness of the structure.

In doing so, we end up with a covering system like tiles, making it possible to protect a building from water infiltration while avoiding the implementation of any seal.

As illustrated in Figures 1 and 2, the adjustment device 100 of the invention comprises a profile 10 and two structural parts 20 mounted to slide on either side of the profile 10. Such a device 100 is intended to form the width of a frame 50 ( ) supporting a photovoltaic panel 51.

For this purpose, the section 10, as illustrated in the , comprises a bottom wall 16 and two side walls 15, oriented perpendicularly with respect to the bottom wall 16, the assembly thus constituting a chute or channel 13.

The side walls 15 are provided at their free upper edge with slideways 12 . To do this, the end of the side walls 15 is curved downwards to form a slot extending over the entire length of the section 10 .

In the example described, the profile 10 has a length of between 0.5 and 2 meters and a width of between 7 and 15 cm. The height of the side walls 15 is typically between 2 and 5 cm. The sections 10 are preferably made of a metallic material having good properties of resistance to deformation and to oxidation in the presence of water, typically aluminum or stainless steel. They can be obtained using dies, making it possible to conform them in a single operation, or even result from a bending operation.

The lower wall 16 internal to the chute 13 comprises a number of grooves 19 , the function of which will be described later.

As shown on the , a structural part 20 comprises a bottom wall 29 and two internal side walls 22 extending perpendicularly relative to the bottom wall 29 so as to form a channel 23.

The inner side walls 22 are provided at their free upper edge with rails 21 . For this purpose, the end of the internal side walls 22 comprises a rounded portion of greater thickness. This rounded portion is configured to penetrate into the slot of the slide 12 of the profile 10 via a lateral end of the slide 12 . Thus, only a lateral sliding movement makes it possible to disengage the structural part 20 from the profile 10 .

A movement of the two parts apart would be blocked by the rounded portion which could not be easily disengaged from the slide because of its greater thickness.

The structural part 20 also comprises two external side walls 42 extending perpendicularly relative to the lower wall 29, forming, in association with the internal walls 22 , side gutters 24 .

In the example described, the structural part 20 has a length of between 15 and 25 cm, and a width of between 7 and 15 cm. The height of the inner side walls 22 is between 2 and 5 cm and the height of the outer side walls 42 is between 1 and 4 cm. Preferably, the height of the outer side walls 42 is lower than that of the inner side walls 22 so as not to interfere with the fixing of the photovoltaic panel 51 on the profile 10 . The structural parts 20 can also be made of a metallic material having good properties of resistance to deformation and to oxidation in the presence of water, typically aluminum or stainless steel. Alternatively, they can be made of plastic, and typically fireproof polypropylene, with the aim of optimizing the entire frame and roof, the fireproof nature, and therefore reduce the risk of fire spreading. .

According to one embodiment of the invention, the internal side walls 22 comprise a plurality, and for example between 1 and 10 discontinuities 26 . These are thus defined by a succession of lugs 25 , comprising at their free upper edge the rounded portion of greater thickness. The lugs 25 have for example a width of between 1 and 2 cm.

Discontinuities 26 may also extend to bottom wall 29 . The latter thus comprises an alternation of extra thicknesses 43 and discontinuities 44 . The extra thicknesses 43 connect the two lugs 25 of the two internal side walls 22 and in fact have the same width as the lugs 25 .

Discontinuities 26 and 44 provide a drip-breaker function. They make it possible to create a barrier to the progression of drops which would run off along the side walls 15 of the section 10. In order to reinforce this drip-breaking effect, elements 47, as illustrated on the , can be added to at least partially fill the discontinuities 26. The elements 47 are for example formed by a polyurethane foam, in particular with open cells.

Advantageously, the lower wall 29 also comprises, at one end, a rim 45 connecting the outer side walls 25 and making it possible to prevent water from flowing beyond this end, and therefore to compromise the sealing of the frame 50 .

The end opposite the rim 45 is intended for the evacuation of the water contained in the structural part 20 . For this purpose, this end is preferably flared, that is to say that the lower wall 23 comprises a trapezoidal portion 46 on which the internal 22 and/or external 42 side walls extend forming an angle of 30 to 60 degrees relative to the longitudinal axis of the profile 10 .

Preferably, this trapezoidal portion 46 is inclined downwards by an angle of 1 to 10 degrees with respect to the longitudinal axis of the section 10 .

The structural parts 20 are advantageously identical so that they can be easily interchanged.

The structural parts 20 are mounted on the profile 10 by positioning the end of the structural parts 20 having the flange 45 against the profile 10 and by aligning the internal side walls 22 in the slots located at the level of the free upper edge of the side walls. 15 of profile 10 . A lateral movement in the direction of the profile 10 thus makes it possible to cause the structural parts 20 to slide on the profile 10 .

The width of the device 100 can be adjusted by a length corresponding substantially to the sum of the lengths of the two structural parts 20 , to the nearest dimension of cooperation of said section 10 with said structural parts 20 . Thus, for example, if the profile 10 has a length of 1 meter and the profile pieces 20 each have a length of 20 cm, then the device can be adjusted continuously over a length of between 1 and 1.20 meters. . This device 100 therefore advantageously makes it possible to reduce the number of references with profiles 10 of variable lengths since the device 100 now makes it possible to cover a wide range of lengths for a single reference.

As shown on the , the structural parts 20 advantageously include a detent 41 making it possible to block the end of the section 10 and prevent it from protruding from the end of the structural parts 20.

To summarize, when water falls on the photovoltaic panel 51 , it can run off and infiltrate at the level of the lower wall of the panel 51 to form drops in suspension. The drops are received and fill the chute 13 of the profile 10 . In normal operation, that is to say when the quantity of water is sufficiently low, the water flows in the direction of the structural parts 20 and is transferred from the chute 13 of the section 10 to the channel 23 of the parts of structure 20 in order to be evacuated from the device 100 .

Additional evacuation systems have been put in place to prevent the overflow of the chute 13 of the profile 10 and of the channel 23 of the structural parts 20 . Thus, the side gutters 24 , the widening and the inclination of the structural parts 20 make it possible to overcome an excessive flow of water.

The frame 50 is formed of two receiving chutes 30 comprising a bottom wall and two side walls substantially perpendicular to the bottom wall. These receiving chutes 30 are intended to be arranged in the direction of the slope of a roof.

For example, the receiving chutes 30 have a length of between 1.5 and 2.5 meters and a width of between 7 and 15 cm. The height of the side walls is between 2 and 5 cm. The receiving chutes 30 are advantageously made of a metallic material having good properties of resistance to deformation and to oxidation in the presence of water, typically aluminum or stainless steel.

The frame also includes two devices 100 for adjusting the width of the frame 50 as described above and intended to be arranged in the direction transverse to the slope of the roof.

During assembly of the frame, the receiving chutes 30 are fixed to the frame 300 of the roof by fixing parts 31 , illustrated in FIGS. 7 and 8. These fixing parts 31 comprise a flat portion intended to be arranged facing the reception chute 30 and two side bridges intended to span and hold the side walls of the reception chutes 30 . The fasteners 31 further comprise two lugs having at least one thread allowing a screw to be inserted. The lugs are intended to be arranged and fixed to the frame 300 . The fixing parts 31 advantageously make it possible to hold the receiving chutes 30 on the frame 300 of the roof without drilling them directly, which could compromise the tightness of the frame 50 .

The adjustment devices 100 are then adjusted so that structural parts 20 come to rest on the side walls of the receiving chutes 30 . To do this, the structural parts 20 include notches 28 , as shown in Figures 4 and 5. These notches 28 , located at the level of the underside of the trapezoidal portion of the structural parts 20 are preferably among the number of two. They allow the adjusting device 100 to rest, without slipping, on the receiving chutes 30 and ensure the tightness of the frame 50 at the level of the transition devices 100 from adjusting devices 100 to receiving chutes 30 .

Indeed, the notches 28 have a drip-breaker function because they increase and complicate the path to be traveled by the drops which would trickle under the structural parts 20 so that the drops end up falling back into the receiving chute 30 .

The water therefore flows into the receiving chute 30 , from the channel 23 and the side gutters 24 of the structural parts 20 .

The photovoltaic panel 51 is then placed on the frame 50 . It is fixed by means of a selvedge 32 comprising an upper face and two rails extending downwards, perpendicular to the upper face over the length of the selvedge 32 . The upper face of the edge 32 is intended to cover part of the upper wall of the photovoltaic panel 51 , while one of the two rails is intended to rest against the side wall of the photovoltaic panel 51 . Screws 34 make it possible to secure the photovoltaic panel 51 to the fixing piece 31 .

Preferably, several photovoltaic panels 51 are integrated on the frame 300 of the roof. The integration device 200 can form all or part of the roof, as illustrated in the . To this end, the device for integrating photovoltaic panels 51 on a frame 300 is composed of a plurality of frames 50 arranged in the form of a grid. For example, the integration device 200 is composed of two rows of eight photovoltaic panels 51 of the same type, but it can also be formed of a column of photovoltaic panels 1 m wide and of another column comprising 1.2 meter wide photovoltaic panels.

Thus, as illustrated in Figures 7 and 8, the receiving chutes 30 are aligned to form a continuous chute in the direction of the slope of a roof. To do this, the receiving chutes 30 overlap at the top, that is to say that the free lateral edge of the reception chute of a first frame is covered by the free lateral edge of the reception chute d another frame, located directly above the first frame, in the direction of the slope of the roof. Thus, the water, which naturally follows a direction of flow along the slope of the roof, pours from receiving chutes 30 to receiving chutes 30 . This advantageously makes it possible to maintain the tightness of the system and to ensure mutual maintenance of the receiving chutes 30 between them.

The adjustment devices 100 are then arranged in the direction transverse to the slope of the roof and the photovoltaic panels 51 are placed on the frames 50 as mentioned previously.

The edge 32 advantageously makes it possible to fix two contiguous photovoltaic panels 51 in the transverse direction of the slope of the roof. Thus, the two rails 33 of the edge 32 each rest against the side wall of a photovoltaic panel 51 . The two rails 33 are spaced apart by a distance of between 0.5 and 1.5 cm so as to allow the passage of a screw from the upper surface of the selvedge 32 to the fixing piece 31 , in which it is screwed.

The structure therefore forms a sealing barrier in which the water runs off in the direction of the slope of the roof. The receiving gutters 30 located at the lower end of the structure, that is to say at the lowest point of the slope of the roof, discharge the water out of the device, preferably in the direction of a gutter of the roof. .

According to an advantageous embodiment, the integration device 200 can include a top flashing 70, as illustrated in the . This top flashing 70 is formed of at least one plate, preferably metal, arranged at the level of the upper end of the integration device 200 and extending over the entire width of the integration device 200. The top flashing 70 makes it possible to seal the joint between the upper part of the frame 300 covered by tiles and the lower part of the frame 300 covered by the photovoltaic panels 51 and to facilitate the runoff of water towards the photovoltaic panels 51.

Preferably, the top flashing 70 is attached to the frame width adjusters 100 by means of fasteners 60. As shown in the , the fixing piece 60 comprises rails configured to slide in the grooves 19 of the profile 10. A lateral sliding movement in the grooves 19 thus makes it possible to position the fixing piece 60 on the profile 10.

As shown on the , the photovoltaic panel 51 and the top flashing 70 then at least partially cover the adjustment device 100 and the fixing piece 60. In particular, the top flashing 70 comprises a curved portion 71 intended to be positioned in an opening 62 of fixing part 60.

A deflector 72 is then positioned opposite the adjustment device 100 provided with the fixing piece 60 , above the photovoltaic panel 51 and the top flashing 70 .

The deflector 72 and the fixing piece 60 further comprise fixing means such as a thread 61 , cooperating with a screw. The latter makes it possible to fix and hold the deflector 72 on the fixing part 60 , thus trapping in a sandwich the upper portion of the photovoltaic panel 51 and the curved portion 71 of the top flashing 70 .

Thus, the invention is a device for integrating photovoltaic panels on a frame making it possible, on the one hand, to guarantee the tightness of the structure and, on the other hand, to adapt the device to different dimensions of panels. photovoltaic.
