With reference to FIG. 1, an installation is composed of a plurality of juxtaposed panels 1 that can form a flat surface.

The installation comprises a support structure based on fastening profiles extending vertically along the slope of a roof. As shown in Figures 2 and 3, the fastening profiles 2 are placed at a predetermined horizontal spacing substantially corresponding to the width of a panel. Each fastening section 2 is provided with at least one support joint 5. Several panels are placed in connection with two consecutive fastening profiles to form a row, two opposite edges of a panel resting on the support joints 5.

Each fixing profile corresponds to a glazing bead 6 provided with at least one seal 9.

The fastening profiles and the corresponding glazing beads may preferably be models of the SAPA RC System, such models illustrated in FIG. 3 may comprise at each fastening profile 2 two lateral wings 3a and 3b each having a flange of The corresponding glazing beads 6 may comprise a yoke 7 and two longitudinal uprights 8a and 8b in which the seal 9 is housed.

As illustrated in Figures 1, 4 and 5, two successive panels 1a and 1b of a row are interconnected by spacers 10. The spacers 10 form a junction frame panels, they extend horizontally in a spacing predetermined and have two ends 11a and 11b in connection with two consecutive fastening profiles (Figure 1). As illustrated in FIGS. 5, 7 and 9, a spacer 10 comprises a base profile 12 and a covering profile 13 for sealingly connecting a panel located upstream of the spacer in the direction of

the slope of the roof with a panel located downstream of the spacer. The spacers are of sufficient length so that each end 11a and 11b takes support on the support joints of two consecutive fastening profiles.

The frame and the panels are locked when assembling the glazing beads with corresponding fastening profiles. As illustrated in FIG. 5, the installation of the glazing beads 6 on the fastening profiles 2 makes it possible to simultaneously grip the panels and the two ends of each spacer connecting two successive panels of the rows. Thus two consecutive fastening profiles and their glazing beads allow tight sealing of the panels and the ends of the spacers between the support joints 5 and sealing 9 of the fastening profiles and glazing beads.

Preferably, the panels may be of rectangular shape and have two horizontal edges of a predetermined width, and two vertical edges of a predetermined height. Advantageously, the spacer has a length substantially equal to the width of the two successive panels it connects.

According to an improvement illustrated in Figures 1 and 4 to 6, each bead 6 can be screwed to a fastening profile 2 by at least two screws 14a and 14b respectively located upstream and downstream of each spacer 10, in the direction of the slope the roof, allowing a crushing of the support 5 and sealing 9 joints to conform to the shape of the panels and the ends 11a and 11b of the spacer 10. Preferably, the screws 14a and 14b can be introduced by the top of the bead 6 and screwed into a longitudinal protrusion 15 (Figure 3) between the two lateral wings 3a and 3b. This protrusion 15 may be a cavernous body made of a deformable material of aluminum type.

The crushing of the joints depends on the tightening torque of the screws 14a and 14b, the value of the torque is reached when the joints 5 and 9 perfectly match the shape of the panels and the spacer, thus sealing the slight protrusions formed by the spacer above and below the panels at each junction (Figure 5).

As illustrated in FIGS. 5 and 7, a spacer for fastening panels comprises: a base profile 12 provided with a first bearing surface 16 equipped with first male engagement means 17, and a covering profile 13 provided with a second bearing surface 18 equipped with second female engagement means 19. The first male engagement means 17 comprise two parallel walls 20a and 20b separated from each other, and each comprising grooves 21 constituting a thread locking device for a screw 23 passing through the second surface of the cover profile 13, and whose helical surface can be screwed into the grooves of the walls 20a and 20b. Preferably, the spacer comprises a plurality of screws 23. The female interlocking means 19 may be delimited by two parallel sections 22a and 22b and arranged facing one another.

When assembling a spacer, illustrated in FIGS. 5 and 9, two panels 1a and 1b rest on the first bearing surface 16 on either side of the first male engagement means 17. covering profile 13 is then attached to the male interlocking means 17 until contact between the second bearing surface 18 of the covering profile 13 and the panels 1a and 1b. The assembly is then secured by assembly screws 23 placed in a regular pitch to ensure a constant tightening of the two successive panels 1 a and 1 b.

Preferably, the sealing of the junction between two successive panels is provided by a U-shaped seal inserted between the two bearing surfaces 16 and 18 on either side of the female interlocking means 19. As illustrated in FIGS. Figures 5, 8 and 9, each seal 24 is a section whose section comprises a base 25 connecting two parallel branches 26a and 26b. The width of the base corresponds substantially to the thickness of the panels to be connected. Each spacer 10 may then comprise two U-shaped joints located between the panels 1a and 1b to be connected and the spacer 10, the screws 23 then ensuring a constant tightening of the panels and the U-shaped joints 24 on any the length of the spacer 10.

The thickness of the panels in a row may be different, which may cause mounting problems. To address this problem, the base profile 12 and the cover profile 13 may preferably comprise a range of adaptation depending on the height of the panels to be connected. This adaptation range requires that the spacer is H-shaped variable geometry. The adaptation range is then defined by all possible thickness values of panels that can be connected by the spacer. This range has a minimum and a maximum. The minimum can be defined by the height of the female interlocking means and / or the height of the male interlocking means 17, the maximum being defined by the sum of the heights of the male and female interlocking means 17.

When using a variable geometry spacer, the U-shaped seal has a profile capable of accommodating different panel thicknesses. The base 25 of the U-shaped joint 24 is compression-deformable. Compression acts on articulation means. As illustrated in Figure 8, the hinge means may be formed by at least one depression 27 and, preferably, by two notches 28 located at the connection between the base 25 and the parallel branches 26a and 26b.

The depression 27 then allows the deformation of the seal 24 at the junction of the two bearing surfaces. The two notches 28, the section of which is preferably circular, allow the two branches 26a and 26b of the U-shaped joint 24 to approach one another when the base is compressed.

An installation as described can allow the assembly of photovoltaic panels, thermal or simple glazing. When assembling photovoltaic panels, it is important for the cells to capture as much solar radiation as possible. To optimize this radiation capture, the installation will generally be placed on the slope of a roof. The roof can not follow the movement of the sun, especially when the sun is grazing the glazing beads comprise two longitudinal beveled edges 29 (Figure 6) to limit the shading of the cells.

The installation solves the known problems, moreover, during the use of thermal or photovoltaic panels, it may be necessary to dismantle a single panel to make the change, that is why the glazing beads and the covering profiles are screwed, allowing a quick disassembly of a panel.
