Description

Technical area

The invention relates to the field of mounting a photovoltaic installation on a frame covered with tiles.

The invention relates more particularly to a mounting device for mounting a photovoltaic installation on a roof structure covered with tile, a mounting assembly for mounting a photovoltaic installation comprising a plurality of mounting devices, a photovoltaic system comprising such a mounting assembly and finally a method of mounting a mounting assembly on a roof.

Technological background

In the state of the art, there are different types of mounting of a photovoltaic installation.

A first type of mounting, the most widespread, is a mounting integrated into the roof, that is to say that the mounting of the photovoltaic installation is done in place of tiles of the roof. In this assembly, it is therefore necessary to provide sealing means around the photovoltaic installation, therefore between the installation and the tiles still in place. This arrangement if it saves space in height and a complete integration into the structure of the roof, has the disadvantage of increasing the risk of water infiltration at the sealing means.

A second type of mounting is a mounting said to be on elevation, that is to say that the photovoltaic installation is fixed by means of mounting device, above the roof, on or through the tiles coming from s 'anchor on the frame. This type of mounting also presents high risks of infiltration of water or waste, such as sheets, at the mounting devices. In addition, the installation is complex and must be able to compensate for the mounting tolerances of the tiles, these being likely to be significant.

summary

An idea underlying the invention is to propose a mounting device for mounting a photovoltaic installation on a frame covered with tiles which allows, on the one hand to limit the infiltration of water and waste inside the roof and on the other hand, to compensate for the mounting tolerances of the roof tiles. In addition, the mounting device is provided to facilitate the mounting of a photovoltaic installation on a roof already in place.

To do this, according to one embodiment, the invention provides a mounting device comprising:

- a tile intended to cover the frame and having a tile orifice;

- a socket fixed inside the tile orifice, said socket having an opening;

- An anchoring member intended to anchor the photovoltaic installation on the frame, the anchoring member passing through the opening of the socket and being, on the one hand, intended to be fixed to an anchoring support fixed to the frame and, on the other hand, intended to be fixed to the photovoltaic installation;

a cover covering the opening of the socket in order to protect it, the cover being provided with a cover orifice and being fixed to the anchoring member which passes in leaktight manner through said cover orifice, said cover being placed at distance from the sleeve so as to guarantee a tolerance of positioning of the anchoring member with respect to the sleeve.

Thus, the mounting device makes it possible to fix the photovoltaic installation through the roof, via the tile orifice, coming to anchor on the frame using the anchoring member.

The cover prevents water and waste from entering through the opening of the socket by covering it. In addition, the cover not being fixed on the socket and being free relative to the latter, the positioning of the mounting device relative to the tile accepts inaccuracies without the cover exerting mechanical stresses on the socket .

According to other advantageous embodiments, such a mounting device can have one or more of the following characteristics:

- According to one embodiment, the socket comprises an external periphery equipped with at least one stop configured to limit the driving of the socket into the tile. Thus, the socket protrudes from the tile to limit the infiltration of water through the tile orifice, and the stop allows easier mounting of the device by clearly indicating where the insertion depth of the the socket.

- According to one embodiment, the cover has a main wall arranged opposite the opening of the socket and an annular skirt which projects from the main wall in the direction of the tile and which is arranged around the socket. The combination of its annular skirt and the main wall makes it possible to optimally protect the socket by completely covering the top of the socket, which has the consequence of reducing the risks of infiltration of water and / or waste.

- According to one embodiment, the sleeve comprises an annular flange projecting radially outwards in the direction of the annular skirt. The annular flange thus placed makes it possible to fill the space between the sleeve and the cover at the level of the side skirt, which again makes it possible to reduce the risk of water infiltration. The combination of the main wall, the annular skirt as well as the flange allow the device to avoid any problem of infiltration.

- According to one embodiment, the cover has an axis of revolution and the cover orifice is eccentric with respect to said axis of revolution. The main tolerances of relative positioning of the tile relative to the member being directed in a lateral direction which is transverse to the direction of slope of the roof, an eccentric opening of the cover makes it possible to position the cover either with the opening of the cover laterally to the left of the cover axis, or with the hole in the cover to the right of the axis. Thus, this makes it possible to offer a wider range of relative positioning of the anchoring member relative to the sleeve, in the transverse direction, without the cover coming into contact with the sleeve and this while retaining a diameter of restricted cover.

- According to one embodiment, the anchoring member is a stud having a thread, the cover being fixed to the stud by means of at least one nut, preferably by means of two nuts which are mounted on the thread of said stud and arranged respectively on either side of said cover.

- According to one embodiment, the anchoring member is fixed to the anchoring support by means of at least one nut, preferably by means of two nuts which are arranged respectively on either side of said support, preferably on either side of an upper part of the anchoring support.

- According to one embodiment, the sleeve is fixed by gluing in the tile orifice. The purpose of the glue is therefore to fix the socket to the tile but also to form a joint between these two elements, thus avoiding any problem of sealing at this level.

According to one embodiment, the glue can be a polyurethane glue, a mastic glue, or a glue of silane modified polyethers, also called "MS polymer", or any other type of glue allowing the socket to be bonded to the tile.

- According to one embodiment, the sleeve is force-fitted into the tile orifice, preferably, the force-fitting also acts as a seal. Alternatively, the sleeve is provided with a sleeve seal at the fitting.

- According to one embodiment, the cover has a cover seal at its orifice so as to seal the connection between the anchoring member and the cover.

According to one embodiment, the cover has a recess on its main wall allowing the cover gasket to be inserted therein.

- According to one embodiment, the cover seal can be an annular seal, preferably flat. The seal may consist of a flat or slightly curved surface with a thickness greater than the recess so that after tightening it can be crushed while retaining a thickness sufficient to ensure the seal.

According to one embodiment, the tile can be a flat tile, a channel tile, a nesting or sliding tile, strongly or slightly curved, or a tile with a flat column.

According to one embodiment, in the clamped position, the anchoring member is fixed to the upper part of the anchoring support by the pincer grip of the upper part between the upper and lower fixing elements.

Thus, the slider makes it possible to fix an anchoring member to an anchoring support without the need for a fixing hole and by significantly increasing the adaptability of the mounting assembly. With the sliding loosened position of the slide, the anchor can be fixed to the anchor support, placing it optimally for tightening.

According to one embodiment, the anchoring support comprises support holes, preferably of circular or oblong shape, which allows the support to be mounted more easily and more quickly.

According to one embodiment, the assembly comprises at least one reinforcing plate, the reinforcing plate comprising a hole configured to allow an anchoring support to pass through the reinforcing plate, and a lower portion comprising configured fixing holes to allow attachment to an element of the frame, for example using a screw-type fixing device.

According to one embodiment, the reinforcing plate comprises an upper portion where the hole for anchoring support is located and at least two wings located on either side of the upper portion.

According to one embodiment, the hole for anchoring support is of shape complementary to the sectional shape of the anchoring support.

Detailed description of embodiments

In the description and the claims, the term "longitudinal direction" means in the direction of the roof slope and the terms "lateral direction" and "transverse direction" are synonymous and mean in the direction orthogonal to the roof slope and in the roof plan. The term "overhead direction" means a direction orthogonal to the plane of the roof, that is to say orthogonal to the transverse direction and to the longitudinal direction.

FIG. 1 represents a photovoltaic system mounted in elevation on a roof. The photovoltaic system is composed of a photovoltaic installation 2 and several mounting devices 1. The mounting devices 1 are designed to hold the photovoltaic installation 2 in position by being fixed on the one hand to different positions of the photovoltaic installation and on the other hand to a frame 3 of a roof. The frame 3 of the roof is in particular composed of battens which extend in the lateral direction and rafters 4 which extend in the longitudinal direction and which serve as anchor points for the mounting devices 1. The frame 3 is covered of tiles 5 over its entire surface. The formats of the tiles allow a coverage density that can range from 60 tiles per square meter (small formats) to 5 tiles per square meter (large formats). The tiles are laid on the battens, themselves laid on the rafters and traditional purlins or industrial farms. The spacing between rafters or small farmhouses depends on the structural dimensioning of the frame varying according to the type of tile, its slope, its geographic location linked to wind and snow loads. To guarantee watertightness, the tiles can be arranged aligned or offset in the longitudinal direction (creeping direction). The mounting devices 1 are designed to each comprise a tile 6 which is provided with a tile orifice 7 allowing it to be anchored on the rafters 4.

The photovoltaic system of this embodiment which is therefore fixed in elevation makes it possible to avoid having a large length of joint all around the installation as what is done in the assembly integrated into the roof and which was responsible for the problems for sealing photovoltaic systems. In a raised installation, the problems of sealing or water infiltration can arise at the level of the mounting devices 1 because these are directly linked to the roof. This is why the invention presented here aims to solve this problem by providing mounting devices 1 which greatly and durably limit the risks of water infiltration. In addition, in order to facilitate the mounting of the photovoltaic system and to avoid stress concentrations on the tiles 6 provided with tile orifice 7, the mounting devices 1 are designed to include means allowing greater mounting tolerance avoiding thus any problem during the assembly of the photovoltaic system.

Figures 2 to 4 show three types of tiles 6 provided with a tile orifice 7 allowing a mounting device 1 to be anchored to a rafter 4 of the frame 3. The mounting device 1 comprises a socket 8 which is fixed inside the tile orifice 7, this socket 8 having an opening. The socket 8 is also provided with an annular collar 9 projecting radially outwards.

The socket 8 also has an external periphery equipped with at least one stop 10 and preferably at least two stops 10. Each stop 10 is constituted by a protrusion projecting radially outward from the external periphery of the socket and is intended to come into abutment against the periphery of the tile orifice 7. Each stop is thus configured to limit the insertion of the socket 8 into the tile 6. In one embodiment, the two stops 10 are diametrically opposite on either side of the outer periphery of the sleeve 8.

This limitation of penetration allows the socket 8 to protrude from the tile 6 sufficiently to limit the infiltration of water through the tile orifice 7 during the flow of water on the roof.

In the embodiment presented in the figures, the tile orifice 7 is located in the center of the tile 6. It can be envisaged in an alternative embodiment that the tile orifice 7 is offset from the center to vary more precisely the distance between two mounting devices 1, thereby making it easier to mount the photovoltaic installation 2.

As shown in Figure 5, the sleeve 8 is according to one embodiment of cylindrical shape. The douiiie has an opening so that an element can pass through the douiiie 8 along its axis of revolution. Each stop 10 is equipped on the outer periphery of the douiiie 8, preferably at least one stop 10 is located halfway up the douiiie. According to one embodiment, the at least one stop 10 is of rectangular shape, preferably its rectangular shape having its greatest length in the direction of the axis of revolution of the shaft.

FIG. 6 represents a roof structure 3 provided in particular with rafters 4, the surface of which is covered with both standard 5 tiles and specific 6 tiles. The specific cases 6 are provided with tile openings 7, Its sockets 8 being fixed inside the tile openings 7. As can be seen clearly in FIG. 6, the socket 8 protrudes from the roof thus allowing no longer have tile openings 7 at the same height as the water flow on a roof thus avoiding any risk of infiltration.

According to one embodiment, the douiiie 8 is fixed by coloring in the orifice of tile 7 so as to make the connection between these two elements more robust and avoid any untimely separation but also in order to prevent the water from s' infiltrates directly between the tile 6 and the tile 8. In fact, the glue also plays a sealing role at the connection between the tile 8 and the tile orifice 7. Preferably, the glue used is a glue of flexible type. In particular, the adhesive is chosen from: a polyurethane adhesive, a mastic adhesive or an adhesive of silane modified polyethers, also called "MS polymer". These different types of glue have the advantage of being easy to use, of being adapted to external conditions, for example temperature and humidity variations, and of being adaptable for fixing different types of materials.

FIG. 7 represents a roof frame 3 where certain tiles have been removed to display an element, namely an anchoring support 11 which allows the fixing of a mounting device 1 to at least one rafter 4 of the frame 3. In one embodiment, the anchoring support 11 is of elongated shape, the length of which is in the lateral direction of the roof slope. This arrangement of the anchoring support 11 makes it possible to fix an element of the mounting device 1 present in this alignment, even if this element is not directly in the alignment of a rafter. Indeed, when fixing the mounting devices 1, the placement of the mounting devices 1 in the longitudinal direction of the roof slope is known because it corresponds to the row of tiles. However, placement in the lateral direction is more complex since it is necessary that a mounting device 1 is in alignment with a rafter 4 to be able to anchor there. However, in the present invention, the anchoring support 11 overcomes this difficulty by allowing a non-alignment between a mounting device 1 and a rafter 3 thanks to its elongated shape and its arrangement which is in the direction lateral. In addition, its elongated shape can also make it possible to connect several mounting devices 1 on the same row of tiles to the same anchoring support 11. Preferably, the anchoring support 11 is pre-drilled before it is mounted on the frame. 3 thus forming support holes 12, the purpose of pre-drilling being to facilitate the mounting of an anchoring support 11.

In FIGS. 8 and 9, an embodiment of an isolated anchoring support 11 is shown. In this embodiment, the anchoring support 11 is a profiled element of elongated shape. The anchoring support 11 comprises a lower part 13 intended to be fixed to the frame 3, in particular to at least one rafter 4, an upper part 14 linked to an element of the mounting device 1 and an intermediate part 15 allowing the junction between the lower 13 and upper 14 parts. Preferably, the anchoring support has an S-shaped section as can be seen in FIG. 9 which makes it easier to assemble by laterally shifting the upper part from the lower part in order to facilitate mounting on the frame and with each of the mounting devices. In addition, the upper part 14 is, in this configuration, higher with respect to the frame 3 than the lower part 13, thus making it possible to facilitate the connection between the anchoring support 11 and an element of the mounting device 1. According to a embodiment where the anchoring support 11 is pre-drilled, it therefore comprises support orifices 12, preferably of circular or oblong shape. Preferably, the support holes 12 on the lower part 13 and the support holes 12 on the upper part 14 are circular or oblong in shape, the oblong shape being in the longitudinal direction of the support and making it possible to increase the mounting tolerance.

Figures 10 and 11 show a mounting device 1 connected to a rafter 4 of the frame 3 and also connected to a photovoltaic installation 2. The mounting device 1 is intended to be mounted to an anchoring support 11 which is directly fixed to at least one rafter 4 of the frame 3, for example using a screw-type fixing element, preferably the lower part 13 of the anchoring support 11 is fixed to at least two rafters 4. The anchoring support 11, preferably the upper part 14, is connected to an anchoring member 16. In one embodiment, the anchoring member 16 is a stud. In addition, the anchoring member 16 is fixed to the anchoring support 11 by means of two nuts 22 which are disposed respectively on either side of the upper part 14 of said anchoring support 11. Alternatively, the anchor member 16 is fixed to the anchor support with a single nut 22. The anchor member is located inside the opening of the socket 8 which is itself fixed to the orifice of tile 7 of tile 6. The anchoring member 16 passes through the opening of the socket 8.

The anchoring member 16 is also connected to a cover 17. The cover 17 is configured to cover the opening of the socket 8 in order to protect it and also to prevent water and / or waste, such as sheets do not infiltrate through the opening of the sleeve 8. The cover 17 is provided with a cover orifice 20 and the anchoring member sealingly passes through the cover orifice 20, at the using, for example, a cover gasket 21. The cover 17 is placed at a distance from the socket 8 so as to guarantee a positioning tolerance of the anchoring member 16 relative to the socket 8. The cover 17 has a main wall 18 disposed opposite the opening of the socket 8. The cover 17 also includes an annular skirt 19 which projects from the main wall 18 in the direction of the tile 6 and which is arranged around the socket 8. The combination of the annular skirt 19 and of the oi principal 18 make it possible to optimally protect the socket 8 by completely covering the top of the socket 8, which has the consequence of reducing the risks of water infiltration. In addition, the annular flange 9 of the sleeve 8 projecting radially outwards in the direction of the annular skirt 19 makes it possible to reduce the clearance between the sleeve 8 and the cover 17 at the level of the side skirt 19 which has the consequence reduce the risk of water infiltration. The cover gasket 21 is located in a recess in the main wall 18 of the cover 17 and is of flat shape, the thickness of which is greater than the recess so that after fixing the cover 17 with the anchoring member 16, the seal fulfills its sealing role. The combination of the main wall 18 fitted with the seal 21, the annular skirt 19 and the collar 9 allow the mounting device 1 to avoid any problem of infiltration. The cover is fixed to the anchor member 16 by means of at least one nut 22, preferably two nuts which are mounted on the anchor member 16 and disposed respectively on either side of said cover 17 The clearance between the collar 9 and the cover 17 is greater than or equal to 4mm.

The anchor member 16 is then connected to the photovoltaic installation by means of a flange. The flange is fixed to the mounting device 1 by being tightened on the anchoring member 16 between a nut 22 and the cover 17. The flange is then connected to a rail which is linked to a frame of the photovoltaic installation 2.

Figures 12 to 14 show an embodiment of a cover 17 isolated from the other components of a mounting device 1. As said previously, the cover 17 has a main wall 18 and an annular skirt 19. In addition, in this embodiment, the cover 17 has an axis of revolution and the cover orifice 20 is eccentric with respect to said axis of revolution. The eccentric cover hole 20 allows the mounting device 1 to be easier to mount. Indeed, by placing itself in the lateral direction, the cover 17 therefore has two possible positions, the orifice to the left of the axis of the cover or to the right. These two positions allow the device to be able to make up for mounting tolerances.

FIG. 15 represents an embodiment of a cover seal 21. In this embodiment, the cover seal 21 is a flat seal of annular shape. The seal 21 is intended to be inserted into the recess of the main wall 18 of the cover 17.

Figures 16 and 17 show a second embodiment of the anchoring support 11 which is fixed to a traditional frame 3 consisting of rafters 4 having a substantial section, an anchoring member 16 of the mounting device 1 being linked to the support d anchorage 11. For reasons of readability, the tile provided with an orifice 6 and the socket 8 are not shown in these figures.

As in the embodiment of FIGS. 8 and 9, the anchoring support 11 is a profiled element of elongated shape comprising a lower part 5 13 intended to be fixed to one or more rafters 4, an upper part 14 linked to an element of the mounting device 1 and an intermediate part 15 allowing the junction between the lower 13 and upper 14 parts. The cross section of the rafters 4 being of sufficient dimensions, the anchoring support 11 is fixed directly by its lower part 13 to one or more rafters, for example using a screw.

In the embodiment of Figures 16 and 17, the intermediate part 15 is composed of two branches arranged on either side of the lower part

13. The upper part 14 is also composed of two branches arranged on each of the branches of the intermediate part 15, the branches of the upper part 14 being directed towards one another in a manner substantially parallel to the lower part 13. The lower part 13, the upper part 14 and the intermediate part 15 thereby delimit an interior space 33 of the anchoring support 11. As can be seen in FIGS. 16 and 17, the anchoring support therefore has a C-shaped section. More particularly, the anchoring support 11 can have a so-called rectangular C-shaped section when the cross-sectional dimension of the branches of the intermediate part 15 is less than the cross-sectional dimension of the lower part. 13. The anchoring support may also have a so-called square C-shaped section when the cross-sectional dimension of the branches of the intermediate part 15 is equal to the dimension in lower section 13.

The anchoring member 16 of the mounting device 1 is fixed to the anchoring support 25 using an upper fixing element 25 and a lower fixing element 26. In fact, as can be see Figures 16 and 17, the lower fixing element 26 is housed in the interior space 33 of the anchoring support 11 and is fixed to the lower end of the anchoring member 16, for example by screwing. The upper fixing element 25 is aligned with the lower fixing element 26 in the zenithal direction and is situated outside the interior space 33 so as to be crossed by the anchoring member 16. From in this way, the lower and upper fixing elements 25, 26 are located on either side of the upper part 14 of the anchoring support 11. A nut 22 placed on the anchoring member 16 then presses against the using the clamping force of the nut 22 on the anchor member 16 the upper fixing element 25 against the upper part 14 of the anchor support 11. Thus, the anchor member 16 is fixed to the anchoring support 11 by the pincer grip of the upper part between the upper and lower fixing elements 25, 26.

FIG. 18 represents the second embodiment of the anchoring support 11 which is this time fixed to an industrial frame 3 made up of small width trusses 24 as well as counter-lattices 23. Unlike the rafters 4 of a traditional frame 3, the farms 24 do not allow, by their size, to properly and directly fix the anchoring support 11. In this case, it seems advantageous to use a reinforcing plate 27 making it possible to link the counterplate 23 and the farmhouse 24 to the support anchoring 11.

As can be seen in particular in FIG. 19, the reinforcing plate 27 comprises a lower portion 28, an upper portion 29 and two wings 30 located on either side of the upper portion 29. The wings 30 are designed so to be oriented orthogonally to the lower and upper portions 28, 29. The wings 30 and the lower portion 28 are provided with fixing orifices 32. The upper portion 29 is in turn provided with an orifice 31 of shape complementary to the shape in section of the anchoring support 11 so that the anchoring support 11 can be introduced into the orifice 31. In this way part of the upper portion 29 is housed in the interior space 33 of the support d anchoring 11 when the reinforcing plate 27 is in the mounting position.

As can be seen in FIG. 18, so as to fix or improve the fixing of the anchoring support 11 to a small farm 24 and a counter-plate 23, the reinforcing plate 27 is inserted on the anchoring support 11 via the orifice 31. In this way, the lower portion 28 is thus pressed against the farmhouse 24 and the counter-lattice in the lateral direction and the wings 30 come to be placed above the counter-lattice 23 on either side of the support. anchoring 11. With the aid of fixing devices such as for example screws, the lower portion 28 is fixed to the farmhouse 24 and the counterplate 23 by introducing the fixing devices into the fixing holes 32 and the wings 30 are fixed to the counterplate 23. Thus, the reinforcing plate 27 surrounds the anchoring support 11 using its shape complementary to the orifice 31 and is fixed securely to the farmhouse 24 and the counterplate 23 in multiple directions so to fix er reliably or improve the fixing of the anchoring support 11 to the frame 3.

On a roof under construction, the photovoltaic system, composed of a photovoltaic installation 2, a plurality of mounting devices 1 and a plurality of anchoring supports 11, is first installed by fixing the supports d anchoring 11 to the frame 3, with or without the aid of reinforcement plates 27, then by placing the tiles 6 provided with tile orifice 7, sockets 8 being previously fixed in the tile orifices 7, then fixing the anchoring members 16 to the anchoring supports 11 through each of the openings of the sockets 8 and finally to fix each of the covers 17 to each of the respective anchoring members 16. Preferably, the anchoring supports 11 are drilled before the step of fixing the anchoring supports 11 on the frame 3, so as to form support holes 12. This drilling before installation on the frame makes it possible to reduce the assembly time on the roof.

During a roof renovation to install a photovoltaic system, it is necessary first of all to remove part of the tiles 5 in order to be able to fix on the frame 3, the anchoring supports 11, then to carry out the same steps as during a roof construction.
