Description

Sealing device for a wall formed of a plurality of juxtaposed solar panels

The present invention relates to a device for sealing a wall formed of a plurality of juxtaposed panels, of the solar panel type, assembled so that the upper faces of the plurality of said panels, which define the outer face of the wall, are arranged in a smooth surface. The solar panels can be of any type, and are more particularly made on the basis of photovoltaic panel technology. The main object of the present invention is to propose an integrated photovoltaic wall sealing device simultaneously producing the electricity production and the sealing of the wall, in particular against bad weather and in particular with water, while allowing a structure of simplified wall to make assembly easy and fast, with a reasonable cost of production and implementation. Another object of the present invention is to provide a sealing device having aesthetic characteristics.

Another object of the present invention is to provide a sealing device having good protection against theft of panels. More specifically, said sealing device is characterized in that it comprises: a plurality of parallel longitudinal longitudinal beams for supporting said solar panels, a first panel at least of said plurality of solar panels comprising a first filler plate for capturing solar energy, and a first frame surrounding said first plate, said first frame having first and second longitudinal sides and third and fourth transverse sides; sealing means of said first solar panel with the juxtaposed solar panels, comprising: a first wall seal fixed and extending on one of said first and second longitudinal sides of said first frame, said first seal covering the edge of the longitudinal side opposite a second panel juxtaposed at said first panel, and - a second wall gasket attached and extending r one of said third and fourth transverse sides of said first frame, said second seal covering the edge of the transverse side vis-à-vis a third panel juxtaposed to said first panel. The sealing device according to the invention provides a seal of the discretized wall, built by the successive assembly of the solar panels, each panel which is installed having sealing means cooperating with those of two juxtaposed panels already laid to form a Sealing on all four sides of the panel that is installed. Thus, when the plurality of solar panels has been installed, the tightness of the wall has been simultaneously achieved.

Tightness as a function is conceived as inseparable from the solar panels which each provide its own wall-sealing part for its integration into it. In addition, the sealing device according to the invention contributes to ease of maintenance of the wall in case of replacement of a panel or intervention on a panel, the affected sealing being restricted to the local level of the panel removed and replaced or replaced, and redone by sealing the replacement panel or the same panel when it is put back in place, if necessary, without the operator having to intervene specifically on the integral seals of the adjacent panels remained in place during the intervention. The panels in addition are an integral part of the waterproofing of the roof. According to an advantageous characteristic, said first and second seals respectively adopt a T-shaped cross-section, the transverse bar of the T covering two juxtaposed edges of two juxtaposed panels, and the vertical bar of the T being associated with said first frame. According to an advantageous characteristic, the vertical bar of the T comprises at its free end a longitudinal return extending in the direction of the transverse bar of the T, said longitudinal return being engaged in a groove of said first panel frame for fixing said seal sealing on said first panel. According to an advantageous characteristic, the longitudinal return and the crossbar portion of the T vis-à-vis said longitudinal return, form a clipping clip of the seal on the edge of said first frame. According to an advantageous characteristic, said first and second seals are profiled joints of identical cross section. This feature allows uniformity of the wall joints with a single section in the longitudinal direction as in the transverse direction of the wall. According to an advantageous characteristic, said first and second seals are bi-hardness joints, the transverse bar of the T having at its two transverse ends respectively at least two longitudinal sealing lips made of a flexible elastic material, the structure T being made of a rigid or substantially rigid plastic material so as to impart to the seal its mechanical strength for a connection thereof with the panel frame.

The flexible lips perform the sealing of the wall by pressing on the outer surface of the panels, in particular bearing on the frame, this support ensuring the seal being made possible by the mechanical strength of the rigid or substantially rigid T-joint profile, which allows the panel on which the seal is attached, to exert pressure, via the flexible lips, on the adjacent panel through the U-shaped interlock on the first spar on the one hand and thanks to the fastening means of the second side of the first frame to the second spar on the other hand. According to an advantageous characteristic, a plurality of crosspieces is disposed between the longitudinal longitudinal members of said plurality of longitudinal longitudinal members, a cross member being placed in abutment on a first and a second longitudinal longitudinal stringers so as to provide support for the first and third frames of the first and third panels juxtaposed by their third and fourth transverse sides, respectively, perpendicular to said first and second longitudinal sides thereof. The sleepers make it possible to consolidate the supporting structure made up of the longitudinal members and crosspieces in this case, by allowing a better distribution of the forces exerted on the wall, for example snow or weight of people, while ensuring a good seal by the increased rigidity in the transversal direction in relation to the strength of the frame. The sleepers also have a function of draining water that could seep through the wall. The sleepers also allow a better setting of the panels in the direction of the slope. According to an advantageous characteristic, said first frame of said first panel consists of four assembled section sections between which said first filler plate is fixed. The structure of the panels from a frame formed of sections allows a simple construction of panels whose solar plates can be naturally trapped in the frame after the assembly of the latter. In addition, the method of construction of panels from profiles reduces manufacturing costs and assembly possibilities. Other benefits will be developed further. According to an advantageous characteristic, said four section sections constituting said first frame of said first panel, adopt identical transverse sections and define a longitudinal recess whose cross section adopts a U-shaped shape, in which the edges of said first filler plate to capture solar energy are nested. The four constitutive profiles of the frame advantageously identical allow a simplification of manufacture while nevertheless responding to an asymmetry in the assembly of the frame on the longitudinal longitudinal members, by interlocking one side and simple support of the other, as will be explained with the description of an exemplary embodiment of the invention. According to an advantageous characteristic, said four section sections constituting said first frame of said first panel are made of a thermally insulating material.

The thermally insulating material may be any suitable rigid plastic material ensuring both a good mechanical strength of the panel and a thermal insulation forming a thermal break wall, at cost costs improved due to the constitution by profiles of these frames . The panel with its frame is thus thermally insulated from the supporting structure. A thermally insulating frame will also advantageously be electrically insulating to ensure the safety of people in the case of a photovoltaic nature of the panel, thus avoiding having to connect these panels to the ground, if any, for the same level of security.

According to an advantageous characteristic, said first and second seals of a first panel are identical for the panels of said plurality of juxtaposed panels.

This characteristic makes it possible to offer a single seal profile for sealing the wall. According to an advantageous characteristic, said first and second seals are joined at an angle of said first frame by a corner sealing piece covering the ends of said first and second seals. According to an advantageous characteristic, said angle sealing piece is fixed to said angle of said first frame so that it forms two free covering edges, respectively extending said first and second seals. According to an advantageous characteristic, said second wall seal is fixed and extends on said third transverse side of said first frame, said third transverse side being the lower side of said first frame in position on the wall. This feature contributes to an improvement in the effectiveness of the sealing device according to the invention, as developed later.

Other characteristics and advantages will become apparent on the following reading of the description of an exemplary embodiment of a sealing device according to the invention, accompanied by the drawings, an example given by way of nonlimiting illustration.

Fig. 15 is a view similar to Fig. 14, the attachment point being shown exploded. The sealing device of a wall 1 shown in the figures, more particularly shows a waterproof roof which is advantageously integrated into a frame (not shown) and forms the integral roof of said frame, 10 having its supporting structure, as detailed below. below. Any beams arranged transversely under the longitudinal longitudinal members of the wall 1 are considered part of the frame and have not been shown. Figure 1 shows four panels 2 juxtaposed. The roof has a plurality of panels which covers the entire area required from substantially identical solar panels. The roof 1 partially shown in FIG. 1 is formed of a plurality of juxtaposed panels 2, of the solar panel type, preferably of the photovoltaic type, assembled so that the upper faces 3 of the plurality of panels 2, which define the outer face 4 of the roof, are arranged on a smooth surface P. The folded superimposed transverse sections of Figure 1 substantially show the alignment of the upper faces of the panels 2. Thus, the solar panels 2 do not overlap edge to edge, with the exception of the seal 30 as will be explained later; two slices of solar panels 2 juxtaposed are arranged face to face longitudinally and transversely directly or indirectly, in the latter case with a portion of a crossbar between the two in the transverse direction, and / or 35 with a portion of the spar between the two in the longitudinal direction, as will be further developed later.

The waterproof roof 1, as shown more particularly in FIGS. 1 to 6, advantageously comprises: a plurality of parallel longitudinal longitudinal members 5 supporting the solar panels 2, constituting the bulk of the supporting structure of the solar panels, having a function of chevrons a first panel 2a at least of the plurality of solar panels comprising a first filler plate 6 for capturing solar energy, and a first frame 7a surrounding the first plate 6, the first frame 7a comprising on at least a first 9 of its longitudinal sides a longitudinal rib 8 extending parallel to the smooth surface P, and on the second longitudinal side opposite the first 9 longitudinal side, a lower plane bearing 11 extending parallel to the smooth surface P. The roof 1 shown in the figures, and more particularly in FIGS. 5 and 6, additionally and advantageously comprises: minus a first longitudinal spar 5a supporting the first frame 7a comprising: - on a first 12 of its two longitudinal sides, a longitudinal housing 13 in U whose inner faces 25 of the legs of the U extend substantially parallel to the smooth surface P , and whose opening of the U opens on the first longitudinal side of the first spar 5a in a plane perpendicular to each longitudinal housing 5 of opens the same perpendicular or substantially smooth surface P, so that longitudinal 13 in U of a spar the plurality of longitudinal spars first 12 side of each longitudinal spar 5 of support, and - at least a second longitudinal spar 5b support 35 of the first frame 7a, parallel and successive to the first longitudinal spar 5a support of the first frame, and comprising: - on a second 14 of its longitudinal sides located vis-à-vis the first 12 longitudinal side of the first longitudinal spar inal 5a, a plane support 15 extending parallel to the smooth surface P, cooperating with a longitudinal free space 16 situated above the flat support 15 and extending in a direction perpendicular to the flat support 15, such that: - the longitudinal rib 8 situated on the first side of the first frame 7a, extending parallel to the smooth surface P, is fitted into the longitudinal U-shaped housing 13 of the first side of the first longitudinal support spar 5a of the first frame 7a, as shown in FIG. 6 with the panel 2 to the right of the figure, and that the lower planar support 11 located on the second side of the first frame 7a, extending parallel to the smooth surface P, is in contact with the plane support 15 of the second longitudinal side of the second longitudinal support spar 5b of the first frame 7a, successive to the first longitudinal spar 5a, in order to bind the first frame 7a to the first 5a and second 5b longitudinal members successive longitudinal axes through the first two first and second longitudinal sides opposed to each other of the first frame 7a, by a partial connection to a degree of freedom in rotation, as shown in FIG. 6, considering that the interlocking U-shaped frame on the spar confers, by its play or its elasticity, a certain limited freedom in rotation of said frame, about a longitudinal axis, relative to said spar.

In FIGS. 2, 3, 4, 5, 6 and 8, the solar panels 2, their respective frame 7, have respectively been referenced, respectively, 2a, 2b, 2c, on the one hand and 7a, 7b, 7c, on the other hand because the panels 2 considered are identical, as well as their constituent frame 7; the index a, b, or c assigned to these references 2 or 7 indicates that it is the panel 2 or frame 7 considered for the index a, of the panel 2 or frame 7 which is adjacent thereto transversely for the index b, and panel 2 or frame 7 which is longitudinally adjacent thereto for index c, as shown in FIG. 1; the longitudinal longitudinal members 5 have also been referenced 5a or 5b indifferently in Figures 5, 6, 11, 12, and 13, because these longitudinal longitudinal members 5 are advantageously identical in the example shown. FIG. 5 shows a mounting view of a panel 2 in which the references a and b for the longitudinal members 5 apply to two longitudinal members 5 supporting a solar panel 2. The roof partially shown in the figures also comprises: advantageously fastening means 17 on the second side of the first frame 7a to the second longitudinal spar 5b, cooperating with the U-shaped interlock located on the first side of the first frame to fix the latter to the first 5a and second longitudinal 5b longitudinal spars, - According to the invention sealing means 18 of the first solar panel 2a with the solar panels juxtaposed, as will be explained later. The assembly structure of the solar panels 2 with the support members 5 is described here by way of example only, and offers good overall strength of the wall 1, while allowing quick installation by interlocking or embedding and pivot panels 2 along a longitudinal interlocking axis, successively as will be explained in detail below. The panels 2, in direct contact with the longitudinal members 5, are an integral part of the wall 1 and participate in the resistance thereof. The wall 1 described advantageously allows the use of identical solar panels whose outer surface exposed to the sun forms a smooth surface, the slices of the constituent frames of the solar panels being vis-à-vis without overlap or overlap. In the wall 1 described, the solar panels and the support profiles advantageously cooperate directly between them by interlocking or embedding for better overall strength of the wall. Other methods of assembling the panels on the supporting structure may be suitable for the sealing device according to the invention.

The solar panels 2, as shown more particularly in FIGS. 2 to 4, respectively comprise, by way of example, a filler plate, preferably of known photovoltaic plate 6 type or laminated, and which will therefore not be described in more detail here. . It will be simply stated that the plate 6 may comprise, in a known manner, from the outside towards the inside, a glass layer, a first encapsulant layer, photovoltaic cells, a second encapsulating layer, and a protective film in under face.

The solar panel 2 further comprises, in known manner, an electrical connection box (not shown), disposed under the plate 6 inside the frame, which allows to connect the panels together, and to make an electrical circuit. The connection box also has a role of electrical protection. This plate 6 is enclosed in the frame 7 which has the following functions: - to give the panel 2 its mechanical strength, and in particular its intrinsic rigidity, especially with a view to its transport, and its handling during the assembly of the roof, - to protect the plate 6 against possible breakage, thanks to the resistance conferred by the frame 7 secured, and in particular the edges of the plate 6 against shocks for example, - participate in the strength of the roof, thanks to the inertia of the cross section the frame, and by its connection to longitudinal longitudinal members 5; the frames 7 are thus an integral part of the supporting structure of the roof. Preferably, the frame 7 of a panel 2 consists of four section sections assembled between which the photovoltaic plate 6 is trapped and fixed. For this purpose, the four section sections constituting the frame 7 of a panel 2, advantageously adopt identical cross-sections, as shown in FIGS. 2 to 4 for the longitudinal sides of the frame, and define a longitudinal housing 22 whose cross section transverse adopts a U-shaped inward facing frame, wherein the edges of the photovoltaic plate 6 are nested.

Thus, because of the identity of the sections of the frame 7, the rib 8 is peripheral around the frame. The four section sections constituting a frame 7 of panel 2 are advantageously made of a thermally insulating material, for example a plastic, polyamide or the like, rigid, and having mechanical strength characteristics appropriate to the needs. The thermally insulating frame advantageously furthermore allows electrical insulation between the photovoltaic plate 6 and the longitudinal longitudinal members 5, in order to ensure the safety of the persons in the event of an electrical fault on the photovoltaic plate 6, avoiding having to connect the panels. photovoltaics to the ground. It should be noted that the frame 7 can also be made of a light alloy from section sections, advantageously also identical, insofar as the thermal / electrical insulation of the roof would be less dominant or managed differently. Referring to FIGS. 2 to 4, it can be seen that the cross-section of the constituent section of the frame 7 advantageously adopts a shape of two U's inverted and secured by one of their branches, a first U in the upper part of the section, facing the inside the frame for fixing the photovoltaic plate 6, and in the lower part, a second U facing outwardly of the frame 7, the lower branch of the second U being constitutive of the rib 8 of assembly with the spar 5 as explained above. The second U may consist of a double wall, as shown, both to increase the inertia module of the section and to increase the thermal insulation if necessary by the presence of a cellular section for example. The outer portion of the lower branch of the second U is advantageously constitutive of the lower plane support 11 of the frame 7 for the seat thereof on the longitudinal spar 5, as explained above. The frame 7 adopts, for example, a polygonal planar shape, for example preferably rectangular or square, so that the side-by-side assembly of the frames 7 constitutes a construction of puzzle, mosaic or similar type, and covers the surface of the roof. The joining lines of the panels 2 in the direction of the longitudinal members 5 necessarily pass along said longitudinal longitudinal members. The roof shown in the figures, and more particularly partially in FIG. 5, advantageously comprises a plurality of crosspieces 19 arranged between the longitudinal longitudinal members 5 of the plurality of longitudinal longitudinal members 5, a cross member 19 being placed in abutment on two first 5a and second 5b longitudinal longitudinal members so as to provide support for a first 7a and a third 7c frames of the first 2a and third 2c panels juxtaposed by their third 20 and fourth transverse sides, respectively, perpendicular to said first 9 and second longitudinal sides thereof. Two successive crosspieces 19 make it possible to support the same frame 7 by its third 20 and fourth 21 transverse sides as shown in FIG. 5. The crosspieces 19 may for example be derived from profiles, and adopt a single transverse section. for example a U-shaped cross section, the base of the U extends on either side of the branches of the U, by two support wings, respectively, constituting support for the two frames 7 juxtaposed to the same cross 19 on either side of the U, via the lower single support 11 of the transverse sides 20 and 21 of each of the two juxtaposed frames 7, as shown in the detail view of FIG. 1 relating to the section of a crossmember 19 The sleepers 19 may advantageously assume a draining function of the infiltration and condensation water which could appear at the transverse junction of the panels and under the panels 2 themselves, via transverse ducts 30 e drainage formed in the U of the crossbar 19 and for example on one of the extension wings of the base of the U crossbar 19, as shown in said detail view of Figure 1. These transverse conduits 30 drainage on the sleepers 19 open at their ends on two successive longitudinal longitudinal beams 5a and 5b, which take up the drainage of this water via longitudinal conduits 31 collector of all transverse conduits 30 opening on these two sections 5a and 5b, as shown for example in Figure 6 The crosspieces 19 can simply be placed on the longitudinal longitudinal members 5 and made trapped by the fixing of the frames 7 to said longitudinal members as will be explained later, or fixed directly to these side members, for example by screws (not shown). The sleepers 19 are made of metal, for example light alloy, and serve to resume the efforts exerted on the load-bearing structure, weight of the solar panels, wind, snow, or weights of maintenance technicians. In addition, these crosspieces 19 are advantageously used to wedge the panels 2 between them along the axis of the slope. The sleepers 19 will preferably be fixed according to the inclination of the roof, in order to recover the forces due to the weight of the panels 2 in the direction of the slope. The plurality of longitudinal longitudinal members 5 respectively and advantageously, as shown more particularly in Figures 5, 6, 11, and 13, a plurality of sections 5 of identical cross section, including the first 5a and second 5b longitudinal longitudinal members. Referring more particularly to FIG. 6, a longitudinal section adopts any section able to withstand the mechanical strength of the bending carrier structure as a function, in particular, of the weight of the panels, for example an inverted T-shaped cross-section. , preferably honeycombed, the foot bar of the T having at its upper free end the longitudinal groove 13 U-shaped interlocking frames 7 and the single support 15 for said frames 7, as shown in Figure 6 and explained above . The cross members 19 are placed in abutment on the longitudinal sides 12, 14 of the longitudinal members 5, as shown in FIG. 6, for example on longitudinal legs 32 enabling said crosspieces 19 to be screwed to the longitudinal longitudinal members 5 at their ends. The longitudinal longitudinal members 5 are fixed to the frame by beams or the like, in a known manner (not shown). Since the flat support 15 of the spar 5 is located at the upper end of the foot, it will be noted that there is a free space 16 situated above the flat support 15 and extending in a direction perpendicular to the support plan 15, so that the second side 10 of a panel 2 can be placed on the support plane 15, through the frame 7 of the panel, by rotation around the rib 8 of the latter located on the opposite side and fitted into the spar 5 juxtaposed. Referring now more particularly to FIGS. 1 to 11, according to the invention, the sealing means 18 of the first solar panel 2a with the solar panels juxtaposed, comprise: a first fixed wall seal 23 and extending over one of the first 9 and second 10 longitudinal sides of the first frame 7a, the first seal 23 covering the edge of the longitudinal side facing a second panel 2b juxtaposed with the first panel 2a, and a second wall seal fixed and extending on one of the third and fourth transverse sides of the first frame, the second seal covering the edge of the transverse side facing each other. a third panel 2c juxtaposed to the first panel 2a. In the example described and in connection with the described assembly example of the panels, the first roof seal 23 is fixed and extends on the second longitudinal side of the frame 7a of the first panel 2a, which is resting on the plane support 15 of the second longitudinal spar 5b, cooperating with the free space 16 situated above the flat support 15 and extending in a direction perpendicular to it, occupied by the second side of the frame 7a of the first panel 2a. The first seal 23 covers the edge of the first side of a second panel 2b juxtaposed to the first panel 2a, having a second frame 7b having a longitudinal rib 8 engaged in the U-shaped housing 13 of the first 12 side of the second longitudinal spar 5b.

Still in the example described and in connection with the described assembly example of the panels, the second wall seal 24 is fixed and advantageously extends on the third side 20 of the frame 7a, or on the transverse side lower, as shown in Figure 5, so that the panels 2 are placed from bottom to top. In addition, this arrangement of the second seal 24, on the lower transverse side of a panel 2, has the advantage of a reinforced transverse seal with the joints 23, 24 as described below. It is the seals 23, 24 which determine the orientation of a panel 2 on the roof in the case where the four sides of the frame 7 are identical, with respect to its four possible positions.

Advantageously, as more particularly shown in FIGS. 2 to 4, the first 23 and second 24 seals respectively adopt a T-shaped cross-section, the transverse bar 25 of the T covering two juxtaposed edges of two panels 2 juxtaposed, and the vertical bar 26 of the T being associated with the first frame 7a.

The vertical bar 26 of the T preferably has at its free end a longitudinal return 27 extending in the direction of the transverse bar 25 of the T, as shown in Figure 2 or 4, the longitudinal return 27 being engaged in a groove 28 of the first frame 7a of the panel 2a for fixing the seals 23, 24 on the first panel 2a. The sides of the first frame 7a is preferably of identical section, it is advantageous that the first 23 and second 24 seals, are profiled joints of identical cross section. The longitudinal return 27 is inserted in force, by a clipping-type connection, into the groove 28 of the frame 7a, in order to be fixed firmly to it, conferring between each seal 23, 24 and the frame 7a, a complete rigid connection capable of sealing by pressure of the transverse bar of the T on the panel 2b, 2c juxtaposed. The first 23 and second 24 seals are advantageously dual-hardness joints, the transverse bar 25 of the T having at its two transverse ends respectively at least two longitudinal sealing lips made of a flexible elastic material, the structure of the T being made of a rigid or substantially rigid plastic material so as to give the joint its mechanical strength for a connection thereof with the frame 7 of panel 2. In the example shown, each transverse end of the transverse bar 25 of the T preferably comprises two parallel longitudinal lips as shown in Figures 2 and 4 to enhance the seal.

The longitudinal recess 27 and the transverse bar portion of the T face to face, form a clipping clip of the gasket 23, 24 on the edge of the frame 7 as shown in FIG. upstream of the roof, for the transverse seal 24, it advantageously strengthens by its elastic clamping force the sealing of the or lips of the clamp, located opposite the longitudinal return 27. Thus, the placement of the transverse seal 24 in the lower part of the frame 7 (third side 20 in the example) which has to cope with the maximum water flow pressure on the roof, is preferred.

The first 23 and second 24 seals are advantageously joined at an angle of the first frame 7a by a corner sealing piece 33, more particularly shown in FIGS. 5 to 11. This piece 33 of corner sealing , of substantially square or rectangular shape in plan view, covers the ends of the two seals 23, 24 meeting in said angle of the first frame 7a, and form sealing with said ends so that the water can not normally not infiltrate between the piece 33 and the seals 23 and 24. The piece 33 of angle seal is fixed to the angle of the frame 7 by any means, for example by clipping and / or gluing, of such that two sides of the square or rectangle defined by this piece 33 form two free ledges 34, 35 of coverage, respectively extending the first 23 and second 24 seals, optionally and advantageously provided with a m sealing sleeve (not shown), to cover the free ends of the two seals 23, 24 of the two panels 2b and 2c juxtaposed to the first panel 2a, as shown in Figure 9. The bonding of the piece of Angle 33 also advantageously makes it possible to seal the 45 ° angle of the section sections constituting the frame 7. The corner sealing piece 33 is made of a flexible or semi-rigid plastic material. In the example shown, the attachment of the piece 33 in the angle of the frame 7 is in particular made by a bracket 36 of angular positioning, protruding at right angles under the cap 37 of square or rectangular shape, the bracket 36 advantageously comprising a rib 58 fitting into the outer corner edge 39 of the frame 7. In addition, the corner sealing piece 33 preferably comprises a centering stud 38, placed under the cap 37, which advantageously insert in the upper inner corner of the first frame 7a and for example bears on the filler plate 6 of the panel 2a. Three other pads 40, 41, 42, respectively disposed at the other three angles of the cap 37, advantageously and respectively bear on the three photovoltaic plates of the three adjacent panels. The sealing means 18 as described above for the first panel 2a are advantageously identical for the other solar panels of the plurality of solar panels 2. Thus, a panel 2 has only two of its sides provided with a seal, joining in an angle of the panel by means of a piece of sealing angle. As more particularly shown in FIGS. 5, 6, and 11 to 15, the fastening means 17 of the second side of the first frame 7a to the second longitudinal spar 5b, cooperating with the U-shaped interlock located on the first side of the first frame 7a for fixing the latter to the first 5a and second successive longitudinal 5b longitudinal members, advantageously comprise a pivoting flange 29 in a plane parallel to the smooth surface P, having the effect of preventing the rotation of the first panel 2a about an axis parallel to the longitudinal rib 8 of the first frame 7a, by blocking the second side of the first frame 7a between the flat support 15 of the second spar 5b and the pivoting flange 29. In general, the pivoting flange 29 makes it possible to imprison rapidly the second side 10 of the frame 7 on the second spar 5b by a quarter-turn maneuver, and thus realize the fixing of the panel, the first side of it being a prisoner the U-groove of the first spar 5a. The pivoting flange 29 prevents the raising of the panel 2 under the effect of a rotation around the rib 8 constituting the U-shaped socket. To disassemble a panel 2, it will be necessary to deactivate this pivoting flange 29 to allow the bearing to be raised. panel 2 and then its release of the U-fitting, as will be explained later. It is noted in Figure 1 main (top view of the wall 1), the fixing points 17 are not visible, being advantageously hidden under the seals 23; in this figure 1, the attachment points 17 have not been shown on the folded section of the longitudinal members 5, to simplify this section, an attachment point 17 being shown elsewhere in FIG. 6. The fastening means 17 for a panel 2 may comprise several advantageously identical fastening points evenly distributed along the second side 10 of the frame 7 of the panel 2, or evenly distributed along the length of each longitudinal spar 5, as shown in FIG. 13 where three points are seen A particularly advantageous attachment point will now be described with the help of FIGS. 6, 14 and 15 more particularly. An attachment point 17 comprises: a rod 43 intended to be fixed at one end to the longitudinal spar, for example by screwing or the like, in a median zone of the spar 5 left free between the two panels 2a, 2b when the latter are supported on the spar 5; a flange 29 pivoting about the longitudinal axis of the rod 43; A nut 44 screwed onto the other end 47 of the rod 43, which is free, allowing the flange 29 to be immobilized by screwing in the position of holding the panel 2 on the longitudinal spar 5, in cooperation with the U-shaped interlock situated on the first opposite side 9 of the panel 2 considered. The rod 43 preferably comprises a transverse flange 45 positioned substantially midway between its two ends 46, 47, intended to serve, on one of its faces, abutment of depression of the rod 43 in the spar 5, as shown in FIG. 6, and on the opposite side of its faces, bearing for the pivoting flange 29 during screwing by means of the nut 44 so that a pressure is preferably exerted by the flange 29 on the frame 7 after screwing on the nut 44. The end 46 of the rod 43 intended to be inserted into the longitudinal spar 5 may comprise for example a profile giving it a self-tapping capacity as shown in FIGS. The other end 47 of the rod 43 is threaded for screwing the nut 44. The free end 47 of the rod 43 is advantageously provided with a means 50 for direct engagement with a tool (not shown) for screwing. and unscrewing the rod 43, for example e screwing the rod 43 alone, and unscrewing the rod 43 provided with the flange 29 and the associated nut 44. The profiles 5 are advantageously equipped in the workshop with fixing points each consisting of a rod 43, a flange 29 and a nut 44. In case of replacement of a panel 2, the operator, by means 50 direct drive, can disable the attachment point 17 faster quarter turn by partial unscrewing, by acting directly on the rod 43, instead of having to unscrew the nut 44 and to maneuver the pivoting flange 29 to release the second side 10 of the panel 2 before lifting it by pivoting around the U-shaped interlock located on the opposite first side 9 of the frame 7. Once the quarter-turn movement is performed by the operator, the panel 2 is free to be rotated. This engagement means 50 may for example consist of a faceted hole, as shown, accessible from above the end 47 of the rod 43, for an intravis-type key or the like (not shown). The flange 29 consists of an oblong plate at a first end 52 of which is formed a hole 51 for passage of the rod 43, the diameter of which is smaller than the outside diameter of the flange 45. The length of the oblong plate is defined so that the second end 53 of the oblong plate can pass above the rib 8 of the frame 7 placed on the spar 5, when the longitudinal axis of the oblong plate is rotated so as to be perpendicular to the axis longitudinal beam 5 or locking position as shown in Figure 11; in this locking position, the frame 7 is immobilized against the spar 5 and can not be pivoted or lifted. The width of the oblong plate is such that when the longitudinal axis of this oblong plate is rotated so as to be parallel to the longitudinal axis of the spar 5, or positioning position of the panel, as shown in FIG. 13, the frame 7 is released from the spar 5 and can be pivoted about the axis of rotation defined by the rib 8 located on the first side 9 of the frame 7, nested in the U-shaped housing of the adjacent spar 5. The first end 52 of the plate 29 will advantageously be provided with a stop 54, for example a right angle, as shown in FIGS. 12, 14 and 15, intended to prevent the complete rotation of the flange 29 once the latter has been in place. on the spar. The stop 54 is made in such a way that it will limit the rotation of the pivoting flange 29 from its installation position of the panel 2 (FIG. 9) to its locking position (FIG. 11) as explained above, either in the example at a quarter turn rotation of the flange. The limitation of rotation of the flange 29 is advantageously by bearing it against the longitudinal spar 5 by means of the abutment 54, in the example against the outer surface of a longitudinal wall of the spar 5 constituting the housing 13 in U, as shown in particular in FIGS. 6 and 11. FIG. 12 shows the flange 29 in an intermediate position between the locking position of the panel 2 and the positioning position of the panel 2; in this figure 12, the stop 54 is not in abutment against the spar 5. Figure 12 shows further that the locking is oriented, in the example preferably in the direction of clockwise.

The nut 44 must make it possible to immobilize the flange 29 in position perpendicular to the longitudinal axis of the spar 5 to fix the frame 7 of the panel on the spar 5, by screwing the nut on the rod 43 and clamping the flange. 29 pivoting against the flange 45.

It should be noted that the attachment point 17 as described above is, once the panels 2 assembled on the support structure comprising the longitudinal members 5 and possibly the cross members 19, inaccessible, as shown in FIG. mounting panels 2 successively, as will be explained later, this is not a problem for the panel 2a, because at the time of fixing this panel 2a, the adjacent panel 2b is not yet in place, thus releasing the access to the attachment point 17, and so on for the successive panels that can be easily blocked with the fastening means 17 as and when they are laid. However, once all the panels 2 assembled on the longitudinal members 5, in the case of dismantling a panel 2 for maintenance or replacement thereof for example, it is necessary to access the fixing points in order to disable and be able to remove the defective panel wall 1. This access to the attachment points 17 is advantageously under the longitudinal seal 23 of this panel in a location whose access is thus limited and not visible. The deactivation of the fixing point 17 by a direct unscrewing action on the rod 43, of the quarter-turn movement type, reverses the quarter-turn movement of the flange 29 alone for fastening the panel, via the engagement means 50, as well as the position of the longitudinal axis of this rod 43 below the seal 23, facilitates in this case the disassembly of the panel, for example via a hole in the seal 23 above the point which must be deactivated. For this purpose, a mapping of the location of the attachment points 17 will be retained. The hole in the seal, necessary for access of the disassembly tool to the point of attachment, can then, once the panel 2 is put back in place and fixed, be closed by means of a suitable sealant . The engagement means 50 disposed hollow at the end of the axis of the rod 43, advantageously makes it possible to be actuated by a small-sized tool (not shown), such as a screwdriver shaft, an intra-screw key, or the like, in this case of small diameter, according to a rotation around the vertical axis of the rod 43, thus minimizing the hole required to pass through the seal 23. An example of a method of producing a sealing device as described higher by assembly of the wall 1 described above will now be developed. The method comprises the following steps: - preferably producing a plurality of solar panels 2 as previously described, advantageously all identical, - producing a carrier structure, in the example as described above, comprising a plurality of parallel longitudinal longitudinal support spars 5 solar panels 2, and advantageously a plurality of ties 19 associated as described above, so that: - at least a first longitudinal spar 5a supporting the first frame 7a of a first panel 2a has on a first 12 of its two sides longitudinal, a U-shaped longitudinal housing 13 whose inner faces of the legs of the U extend substantially parallel to the smooth surface P, and whose opening of the U opens on the first longitudinal side of the first longitudinal member 5a in a plane perpendicular or substantially perpendicular to the smooth surface P, so that each longitudinal housing e n U 13 of a longitudinal spar 5 of the plurality of longitudinal spars opens from the same first 12 side of each longitudinal spar support 5, and - at least a second longitudinal spar 5b of support of the first frame 7a, parallel and successive to the first longitudinal support beam 5a of the first frame, has on a second 14 of its longitudinal sides located vis-a-vis the first longitudinal side of the first longitudinal spar 5a, a flat support 15 extending in a plane parallel to the smooth surface P, cooperating with a free space 16 situated above the plane support 15 and extending in a direction perpendicular to the flat support 15, - fit the longitudinal rib 8 located on the first longitudinal side of the first solar panel 2a, on the first longitudinal spar 5a located at one lateral end of the supporting structure, and at the lower end of the first spar 5a, in the longitudinal U-shaped housing 13 of the latter whose opening is turned towards the second longitudinal spar 5b in succession, so as to immobilize the first side 9 of the panel 2a on the first spar 5a, in a direction perpendicular to the plane of the wall 1 and the spar 5a while allowing a pivoting of the panel towards the outside about a longitudinal axis of the longitudinal U-shaped housing, - placing the second longitudinal side of the first solar panel 2a, by means of its lower plane support 11, on the support plane 15 disposed of the second longitudinal side 14 of the second longitudinal spar 5b in succession, by rotation of the first solar panel 2a around a longitudinal axis substantially passing through the longitudinal rib 8; advantageously fixing the second longitudinal side of the first frame 7a to the second longitudinal spar 5b, for example by means of three attachment points as previously described, engaged with the second longitudinal spar 5b, making Preferably for each attachment point 17 a quarter-turn movement on a pivoting flange 29, so that the latter passes over the rib 8 of the frame to prevent the pivoting of the first panel 2a, and tighten the flange 29 in the locking position of the first panel 2a by means of a nut 44, - reiterate the steps of interlocking the longitudinal rib 8 and laying the second longitudinal side of the panels, successively for the panels 2 of the plurality of panels, from the first solar panel 2a placed on the first longitudinal spar 5a located at a lateral end of the supporting structure, and in a longitudinal direction and a transverse direction oriented, the orientation of the transverse direction being given by the direction according to which open the housing 13 U longitudinal longitudinal members 5, - fix the panels 2 as and when they are laid, 25 before the nesting of u n juxtaposed panel 2 prevents access to fixing points. The exemplary method of producing a sealing device according to the invention, as described above by assembling a wall 1 as described above is simple and fast; more particularly, the installation of a panel is simplified and fast, made in two operations: fit the rib in the U-shaped groove of the spar and then put the panel on the adjacent spar; the interlocking of the rib can advantageously be done with an inclined panel in order to present the rib in the lower part for the interlocking, then the complete installation of the panel is done by simple rotation, once the interlocking realized, until the support on the spar, under the simple weight of the panel. The solar panels are thus placed successively next to each other respectively in two directions and two single directions of laying, the transverse direction and the longitudinal direction. The single direction of longitudinal laying depends on the location of the transverse seal. The installation of the panels is thus simple and fast.

When laying the panels 2 in the longitudinal direction, in the example of the lower end of the longitudinal spar towards the upper end thereof, the last panel 2 is placed resting on two longitudinal members 5a, 5b successive and preferably against a crossmember 19 each able to take all the more weight of the panel 2 that the wall is vertical. The panels 2 can be laid longitudinally successively for all the panels 2 of a longitudinal row resting on two successive longitudinal members 5a, 5b, then fixing all the panels 2 of the longitudinal row on the spar 5b with the attachment points 17 described above, before installing the panels 2 longitudinally of the successive longitudinal row, resting on the longitudinal members 5b, 5c in order to access the fixing points on the spar 5b. The installation can be done so on until the completion of the roof. The laying of the panels 2 can be carried transversely successively for all the panels 2 of a transverse row resting on all the longitudinal members 5, then all the panels of the upper transverse row. In this installation mode, each panel 2 placed must be immediately fixed with its attachment points 17, because the adjacent adjacent panel would hide access to these attachment points. Once the first lower transverse row of panels 2 has been placed, the operator can set and fix the next upper adjacent transverse row, and so on until the last highest transversal row of the roof.

Another method of laying may be to lay the panels simultaneously in the two transverse and longitudinal directions combined, respecting the orientation of these directions because of the position of the seals 23, 24 covering the panels 2 as explained more high. In all cases of laying mode, the solar panels 2 must be electrically connected together via the connection boxes (not shown), this in a known manner.

According to the described example of a method for producing a sealing device according to the invention, the step of sealing the wall 1 consists in sealing the wall, progressively, by the laying operation. successive solar panels 2 next to each other, each provided with sealing means 18 as described above, the sealing between two juxtaposed sides of two juxtaposed solar panels being achieved by the installation of two panels juxtaposed on the side members and sleepers.

The sealing device of a wall formed of a plurality of juxtaposed panels, according to the invention, is suitable for flat roofs, curved profile facets, slope, horizontal, or vertical walls, depending on the needs depending the disposition of the wall with respect to sunshine.
