Description

TECHNICAL FIELD The invention relates to the field of mounting a photovoltaic installation on a roof structure 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 system.

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

A second type of assembly is an assembly said to be in 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 to anchor on the frame. This type of assembly also has a high risk of infiltration of water or waste, such as leaves, at the mounting devices. In addition, the assembly is complex and must be able to compensate for the mounting tolerances of the tiles, which are likely to be important. summary

An idea underlying the invention is to provide a mounting device for mounting a photovoltaic system on a roof structure covered with tiles that allows, on the one hand, to limit the infiltration of water and waste into the interior of the building. the roof and on the other hand, to compensate for the tolerances of mounting the tiles of the roof. Furthermore, the mounting device is intended to facilitate the installation 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 framework and having a tile hole; a socket fixed inside the tile opening, 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, secondly, intended to be fixed to the photovoltaic installation; a cover covering the opening of the socket to protect it, the lid being provided with a lid orifice and being fixed to the anchoring member which passes through said lid orifice in a sealed manner, said lid being placed at distance from the socket so as to guarantee a positioning tolerance of the anchoring member with respect to the socket.

Thus, the mounting device makes it possible to fix the photovoltaic installation through the roof, via the tile opening, coming to anchor on the frame with the aid of the anchoring member.

The lid prevents water and waste from entering through the opening of the socket by covering it. In addition, since the cover is not fixed on the socket and is free with respect thereto, the positioning of the mounting device with respect to the tile accepts inaccuracies without the cover exerting mechanical stresses on the socket. .

According to other advantageous embodiments, such a mounting device may have one or more of the following features: According to one embodiment, the socket comprises an outer periphery equipped with at least one stop configured to limit the insertion of the socket in the tile. Thus, the sleeve protrudes from the tile to limit the infiltration of water through the tile hole, and the stopper allows for easier mounting of the device by clearly indicating where the embedding depth of the tile is. the socket. In one embodiment, the cover has a main wall disposed opposite the opening of the socket and an annular skirt which protrudes from the main wall towards the tile and which is disposed around the socket. The combination of the annular skirt and the main wall optimally protect the socket completely covering the top of the socket, which has the effect of reducing the risk of water infiltration and / or waste. According to one embodiment, the sleeve comprises an annular flange projecting radially outwards in the direction of its annular skirt. The annular collar thus placed makes it possible to fill the space between the socket and the cover at the level of the lateral skirt, which again makes it possible to reduce the risks of water infiltration. The combination of the main wall, the annular skirt and the collar allow the device to avoid any infiltration problem. According to one embodiment, the lid has an axis of revolution and the lid orifice is eccentric with respect to said axis of revolution. The main relative positioning tolerances of the tile relative to the member being directed in a lateral direction which is transverse to the slope direction of the roof, an eccentric cover hole allows the lid to be positioned with the lid orifice laterally. to the left of the lid axis, or with the lid opening to the right of the axis. Thus, this makes it possible to offer a wider range of relative positioning of the anchoring member with respect to the bushing, in the transverse direction, without the cover coming into contact with the bushing while maintaining 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 nut. stud and disposed respectively on either side of said lid. 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 respectively disposed on either side of said support, preferentially on both sides of an upper part of the anchoring support. - According to one embodiment, the sleeve is fixed by gluing in the tile hole. The purpose of the glue is thus to fix the sleeve to the tile but also to form a seal between these two elements thus avoiding any problem of sealing at this level.

According to one embodiment, the glue may be a polyurethane glue, a putty adhesive, or a modified silane polyether glue, also called "MS polymer", or any other type of glue for bonding the sleeve to the tile. According to one embodiment, the sleeve is force-fitted into the tile hole, preferably the force fitting also acts as a seal. Alternatively, the sleeve is provided with a socket gasket at the fitting. According to one embodiment, the lid comprises a lid gasket at its orifice so as to seal the connection between the anchoring member and the lid.

According to one embodiment, the cover has on its main wall a recess for inserting the cover gasket. According to one embodiment, the lid gasket may be a ring-shaped gasket, preferably a flat gasket. The seal may consist of a flat or slightly curved surface of greater thickness than the recess so that after tightening it can crash while keeping a sufficient thickness to seal.

According to one embodiment, the tile may be a flat tile, a channel tile, an interlocking or sliding tile, strongly or slightly curved, or a flattened tulle.

According to one embodiment, the lower fixing element is located in the interior space of the anchoring support and is fixed to a lower end of the anchoring member. The upper fastening element is aligned with the lower fastening element in the zenith direction and is located outside the interior space so as to be traversed by the anchoring member.

According to one embodiment, in the tightened position, the anchoring member is fixed to the upper part of the anchoring support by gripping 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 orifice and by significantly increasing the adaptability of the assembly assembly. With the slidably loose position of the slider, the anchor member can be attached to the anchor support by optimally placing it for clamping.

According to one embodiment, the anchoring support comprises support orifices, preferably of circular or oblong shape, which enables the support to be mounted more easily and more rapidly.

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

Detailed description of embodiments

In the description and 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 plan of the roof. The term "zenith direction" means a direction orthogonal to the plane of the roof, that is to say orthogonal to the transverse direction and the longitudinal direction.

Figure 1 shows a photovoltaic system mounted on a raised roof. The photovoltaic system is composed of a photovoltaic installation 2 and several mounting devices 1. The mounting devices 1 are designed to keep the photovoltaic installation 2 in position while 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 composed in particular of slats which extend in the lateral direction and chevrons 4 which extend in the longitudinal direction and serve as anchoring points for the mounting devices 1. The frame 3 is covered of tiles 5 on all its surface. The tile formats allow a coverage density ranging from 60 tiles per square meter (small sizes) to 5 tiles per square meter (large formats). The tiles are placed on the battens, themselves placed on rafters and traditional failures or industrial farms. The spacings between rafters or trusses depend on the structural dimensioning of the structure varying according to the type of tile, its slope, its geographical location related to the loads of wind and snow. To guarantee watertightness, the tiles can be arranged aligned or offset in the longitudinal direction (crawling direction). The mounting devices 1 are designed to each comprise a tile 6 which is provided with a tile hole 7 for anchoring on the rafters 4.

The photovoltaic system of this embodiment which is thus fixed in elevation avoids having a great length of joint all around the installation as what is done in the assembly integrated to the roof and which was responsible for the problems. sealing of photovoltaic systems. In a raised installation, the sealing or water infiltration problems can occur at the mounting devices 1 because they are directly related to the roof. This is why the invention presented here aims to solve this problem by providing mounting devices 1 to greatly and durably limit the risk of water infiltration. In addition, in order to facilitate the mounting of the photovoltaic system and to avoid stress concentrations on tiles 6 provided with tile openings 7, the mounting devices 1 are designed to include means allowing greater mounting tolerance avoiding thus any problem when mounting the photovoltaic system.

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

The bushing 8 also comprises an outer periphery equipped with at least one abutment 10 and preferably at least two abutments 10. Each abutment 10 is constituted by a protuberance protruding radially outwardly from the outer periphery of the abutment. socket and is intended to abut against the periphery of the tile hole 7. Each stop is thus configured to limit the depression of the sleeve 8 in the tile 6. In one embodiment, the two stops 10 are diametrically opposed on both sides of the outer periphery of the sleeve 8.

This limitation of the depression allows the sleeve 8 to protrude from the tile 6 sufficiently to limit the infiltration of water through the tile hole 7 during the flow of water on the roof.

In the embodiment shown in the figures, the tile hole 7 is in the center of the tile 6. It may be envisaged in an alternative embodiment that the tile hole 7 is offset from the center to vary. more precisely the distance between two mounting devices 1 thus facilitating the mounting of the photovoltaic installation 2.

As shown in Figure 5, the sleeve 8 is in a cylindrical embodiment. The sleeve has an opening so as to allow an element to pass through the bushing 8 along its axis of revolution. Each abutment 10 is equipped on the outer periphery of the sleeve 8, preferably the at least one abutment 10 is halfway up the sleeve. According to one embodiment, the at least one abutment 10 is of rectangular shape, preferably its rectangular shape having its greatest length in the direction of the axis of revolution of the sleeve.

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

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

FIG. 7 represents a roof structure 3 where some tiles have been removed to visualize an element, namely an anchoring support 11 which allows the attachment of a mounting device 1 to at least one chevron 4 of the frame 3. In one embodiment, the anchoring support 11 is of elongated shape whose length 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 chevron. 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 tile row. However, the placement in the lateral direction is more complex because it is necessary that a mounting device 1 is in alignment with a chevron 4 to be anchored. However, in the present invention, the anchoring support 11 overcomes this difficulty by allowing a non-alignment between a mounting device 1 and a chevron 3 due to its elongated shape and its layout 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 mounting on the frame 3 thus forming support orifices 12, pre-drilling having the purpose of facilitating the mounting of an anchoring support 11.

In Figures 8 and 9, there is shown an embodiment of an anchor support 11 isolated. In this embodiment, the anchoring support 11 is an elongate shaped profiled element. The anchoring support 11 comprises a lower part 13 intended to be fixed to the frame 3, in particular to at least one chevron 4, an upper part 14 connected to an element of the mounting device 1 and an intermediate part 15 allowing the connection between the lower parts 13 and upper 14. Preferably, the anchoring support has an S-shaped section as can be seen in Figure 9 which facilitates mounting by shifting laterally the upper part of the lower part to facilitate assembly 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 facilitating the connection between the anchoring support 11 and an element of the mounting device 1. Embodiment 11 is pre-drilled, so it comprises support orifices 12, preferably of circular or oblong shape. Preferably, the support orifices 12 on the lower part 13 and the support orifices 12 on the upper part 14 are of circular or oblong 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 chevron 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 at least one chevron 4 of the frame 3, for example by means of a fastening element of the screw type, preferably the lower part 13 of the anchoring support 11 is fastened to at least two chevrons 4. 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 respectively disposed on either side of the upper portion 14 of said anchoring support 11. Alternatively, the anchoring member 16 is fixed to the anchoring support with a single nut 22. The anchoring member is located inside the opening of the sleeve 8 which is itself fixed to the orifice 7 of the tile 6. The anchoring member 16 passes through the opening of the sleeve 8. The anchoring member 16 is also connected to a cover 17. The cover 17 is configured to cover the opening the sleeve 8 to protect it and also to prevent water and / or waste, such as leaves seep through the opening of the sleeve 8. The cover 17 is provided with a lid orifice 20 and the anchor member sealingly passes through the lid orifice 20, With the aid of, for example, a cover gasket 21. The cover 17 is placed at a distance from the bushing 8 so as to guarantee a positioning tolerance of the anchoring member 16 with respect to the bushing 8. The cover 17 comprises a main wall 18 disposed facing the opening of the bushing 8. The cover 17 also has an annular skirt 19 which protrudes from the main wall 18 in the direction of the tile 6 and which is arranged around the bushing 8 The combination of the annular skirt 19 and the main wall 18 optimally protects the sleeve 8 by completely covering the top of the sleeve 8, which has the effect of reducing the risk of water infiltration. In addition, the annular flange 9 of the bushing 8 projecting radially outwards in the direction of the annular skirt 19 makes it possible to reduce the clearance between the bushing 8 and the cover 17 at the level of the lateral skirt 19, which has the consequence to reduce the risk of water infiltration. The cover gasket 21 is located in a recess in its main wall 18 of the cover 17 and is of flat shape whose thickness 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 provided with the seal 21, the annular skirt 19 and the flange 9 allow the mounting device 1 to avoid any infiltration problem. The lid is fixed on the anchoring member 16 by means of at least one nut 22, preferably two nuts which are mounted on the anchoring member 16 and disposed respectively on either side of said lid 17 The clearance between the collar 9 and the cover 17 is greater than or equal to 4 mm. The anchoring member 16 is then connected to the photovoltaic installation by means of a flange. The flange is fixed to the mounting device 1 while 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 connected to a frame of the photovoltaic installation 2.

FIGS. 12 to 14 show an embodiment of a cover 17 isolated from the other elements constituting a mounting device 1. As said above, the cover 17 comprises a main wall 18 and an annular skirt 19. Moreover, in this embodiment, the lid 17 has an axis of revolution and the lid orifice 20 is eccentric with respect to said axis of revolution. The eccentric lid port 20 allows the mounting device 1 to be easier to assemble. In fact, by moving in the lateral direction, the lid 17 therefore has two possible positions, the orifice to the left of Axis of the lid or to the right. These two positions allow the device to be able to catch mounting tolerances.

Fig. 15 shows an embodiment of a cover gasket 21. In this embodiment, the cover gasket 21 is a ring-shaped flat gasket. The seal 21 is intended to be inserted into the recess of the main wall 18 of the cover 17.

FIGS. 16 and 17 show a second embodiment of the anchoring support 11 which is fixed to a traditional framework 3 consisting of chevrons 4 having a substantial section, an anchoring member 16 of the mounting device 1 being connected to the support of FIG. Anchoring 11. For reasons of readability, the tile provided with an orifice 6 and the sleeve 8 are not shown in these figures.

As in the embodiment of FIGS. 8 and 9, the anchoring support 11 is an elongated shaped profiled element comprising a lower part 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 portion 15 allowing the junction between the lower portion 13 and upper 14. The section of the rafters 4 being of sufficient size, the anchoring support 11 is fixed directly by its lower portion 13 to one or more rafters for example using a screw.

In the embodiment of Figures 16 and 17, the intermediate portion 15 is composed of two branches disposed on either side of the lower portion 13. The upper portion 14 is also composed of two branches disposed on each of the branches of the intermediate portion 15, the branches of the upper portion 14 being directed towards each other substantially parallel to the lower portion 13. The lower portion 13, the upper portion 14 and its intermediate portion 15 thus delimit a space As can be seen in FIGS. 16 and 17, the anchor support thus has a C-shaped section. More particularly, the anchoring support 11 may have a cross-section. so-called rectangular C-shaped when the sectional dimension of the branches of the intermediate portion 15 is smaller than the dimension in section of the lower portion 13. The anchoring support can also have a so-called square C-shaped section when the section dimension of the branches of the intermediate portion 15 is equal to the dimension in section of the lower portion 13. The anchoring member 16 of the mounting device 1 is fixed to anchoring support 11 with an upper fixing member 25 and a lower fixing member 26. Indeed, as can be seen in Figures 16 and 17, the lower fixing member 26 is housed in the inner 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 fastening element 25 is aligned with the lower fastening element 26 in the zenith direction and is located outside the interior space 33 so as to be traversed by the anchoring member 16. In this way, the lower and upper fastening 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 comes into contact with the using the tightening force of the nut 22 on the anchoring member 16 the upper fastening member 25 against the upper portion 14 of the anchoring support 11. Thus, the anchoring member 16 is fixed to the anchoring support 11 by gripping the upper part between the upper and lower fastening 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 fermettes 24 as well as contrelattes 23. Unlike the rafters 4 of a traditional framework 3, the The trusses 24 do not allow, by their size, to fix the anchoring support 11 properly and directly. In this case, it seems advantageous to use a reinforcing plate 27 making it possible to connect the contralact 23 and the trestle 24 to the support of 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 provided with a hole 31 of complementary shape 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 a portion of the upper portion 29 is housed in the interior space 33 of the support 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 truss 24 and a contralact 23, the reinforcing plate 27 is inserted on the anchoring support 11 via the In this way, its lower portion 28 is thus pressed against the trestle 24 and the contralatte in the lateral direction and the wings 30 are placed above the contralatte 23 on either side of the support. anchoring 11. Using fastening devices such as screws, the lower portion 28 is fixed to the trestle 24 and the contralact 23 by introducing the fixing devices into the fixing holes 32 and the wings 30 are fixed to 23.
