Description

Title of the invention: BUILDING CLADDING COMPRISING A PANEL FIXING STRUCTURE ADJUSTABLE IN POSITION AND METHOD OF INSTALLING SUCH CLADDING ON A BUILDING technical field

[0001] The invention relates to the field of cladding buildings with panels with technical functions, such as insulation, energy storage, air circulation, lighting, display, or aesthetic functions. Previous technique

[0002] A photovoltaic structure integrated into a building is commonly called a "BIPV" (from the English "building-integrated photovoltaics").

[0003] Prior art document EP3182580A1 is known, which describes a photovoltaic module for ventilated facade, comprising a photovoltaic panel consisting of a front pane, a rear pane, laminated films adhering to the panes, and a set of photovoltaic cells arranged between the panes and films, these cells being arranged in parallel rows and separated by conductive tracks; the rear pane of the photovoltaic panel is permanently connected to vertically oriented aluminum carrier profile wings, the webs of which are fitted with profiled hooks at their ends, and the edge of a membrane resting on the horizontal edge of a metal angle with equal branches is adjacent to the lower side of the rear pane.

[0004] Document EP3594427Al describes a system for fixing facade elements, including windows or photovoltaic modules, on a facade with mounting profiles arranged on a building wall, and connecting means that are attached on one side to the rear face of the facade elements and on the other side can be connected to the mounting profiles. The fixing system comprises mounting profiles of a first type and mounting profiles of a second type for a predominantly horizontal arrangement on a substructure of a building wall. Other components of the fixing system are a fixing profile intended to be positioned on the rear of the facade elements, an anchor intended to be removably positioned on the fixing profile, and a sliding support on the second type of profile that is guided longitudinally in the direction of the profile. The mounting profiles, the anchor, and the sliding support are designed to have an initial connection by adjusting form between the anchor and the mounting profile of the first type and a second connection by interlocking between the anchor and the sliding part.

[0005] Document CH708361A1 describes a facade anchor for fixing facade elements to a building wall. It has a first front insertion end for anchoring in a building wall and a second rear end with a fastening option for fixing facade elements. Between the first and second ends is a rod section made of fiber-reinforced plastic. The front end has at least one intermediate section of reduced diameter, and the fiber reinforcement is formed by a fibrous fabric, preferably predominantly unidirectional, or by strands aligned essentially in the longitudinal direction.

[0006] US2020291659A1 describes a profiled element and a facade system for mounting on buildings, having facade panels connected to profiled elements, each profiled element having a receiving section, a fixing section, and a mounting section. The receiving section forms a receiving space at its free end, and the fixing section is formed such that it rests at least partially on the back of the facade panel. The fixing section is positioned relative to the facade panel so that the mounting section extends beyond the facade panel.

[0007] Document EP2180115A1 describes a device comprising a set of L-shaped end pieces connected by a plate-shaped spacer that fills a gap between a support frame and a building envelope panel. The spacer is made of a material with a thermal conductivity of 20 Watts per meter Kelvin to increase resistance to heat transfer between the end pieces. Fastening passages are provided in the spacer and the end pieces, and a fastener, i.e., a rivet fastener, is formed between the end pieces and the spacer by the fastening passages. The spacer is made of a non-metallic material such as wood, a ceramic or polymer material, or metal.

[0008] Document EP2362034A2 describes a support body to which a plate is fixed. The support body is a frameless construction and includes a fastening device for fixing the support body to a building wall. The support body includes an adjustment unit. The distances between a front stop and a rear stop are fixed and adjustable using the adjustment unit.

[0009] Document EP2568095A1 describes a device for a wall assembly of a cladding panel, which forms an intermediate space with a wall, and includes a mechanism for regulating the vertical height of the panel supported by a base fixed to the surface of the panel. The regulation mechanism includes a slide and a screw for controlling the translation of the slide, which also A section for attaching the device to a plate fixed to the wall. The base and height adjustment mechanism are entirely contained within the intermediate space. A second horizontal (depth) adjustment screw for the panel is also entirely contained within the intermediate space and works with the slider; the free end of this second screw has a cam profile that acts on an edge of the plate, thus varying the thickness of the intermediate space.

[0010] However, prior art facade cladding remains difficult to install; the geometric adjustments between panels are delicate and in some cases require significant gaps between the panels. Furthermore, removing these panels is sometimes dangerous. Description of the invention

[0011] The objective of the present invention is to remedy these drawbacks by offering a very versatile facade cladding, with panels of all types, with technical or aesthetic functionalities, and in particular very well adapted to the installation of photovoltaic panels in complete safety for both equipment and personnel.

[0012] The invention relates in particular to a photovoltaic structure integrated into a building, placed on a ventilated facade.

[0013] To this end, the present description relates to a cladding intended for a building, comprising a fixing structure for a panel adjustable in position relative to the structure, the structure comprising a first part intended to be fixed to the building comprising a lower rail and an upper rail each comprising a part with an open hollow profile forming a channel and intended to be mounted parallel, the structure comprising a second part intended to be fixed removably to the first part and comprising a rear panel rail intended to support said panel, the rear panel rail comprising a lower support arranged to cooperate in support with the open hollow profile of the lower rail, the rear panel rail being able to be movable in translation on the lower rail and on the upper rail,the rear panel rail carrying an upper hook assembly comprising a locking hook arranged to cooperate by pinching with the upper rail, the upper hook assembly and the rear panel rail having means for guiding and adjusting in translation, the upper hook assembly being able to be movable in translation relative to the rear panel rail, the upper hook assembly having a movable hook able to be movable in translation along the rear panel rail under the action of the adjustment means for bearing on the upper rail and for vertical adjustment of the rear panel rail relative to the building, and the locking hook being able to be movable, under the action of the adjustment means, in rotation and / or in translation relative to the movable hook, , and the upper hook assembly includes a locking guide having guide grooves cooperating with the movable hook and the locking hook to move from a release configuration to a locking configuration of the locking hook relative to the upper rail and vice versa.

[0014] Thanks to the invention, it is possible to pre-position the panel by means of the lower support inserted into the groove of the lower rail, which bears part of its weight, and then to secure it to the upper rail with the upper hook assembly, in a connection that allows adjustments before locking into position. The configuration of the movable hook in translation allows the position of the panel to be adjusted in a first direction, parallel to the rear panel rail, in particular vertically. It is understood that to move from the release configuration to the locking configuration, the locking hook is brought closer to the upper rail by a kinematic action applied to the upper hook assembly, and that to move from the locking configuration to the release configuration, the locking hook is moved away from the upper rail by a kinematic action applied to the upper hook assembly.

[0015] In the release configuration, the rear panel rail can translate along the upper rail and / or the movable hook assembly can be disengaged from the upper rail.

[0016] The friction between the upper rail and the rear panel rail, combined with the locking mechanism, ensures that the panel remains securely in place even in severe weather conditions (strong winds, wind shear, unusual climatic loads, and the like). The panel can be adjusted in a second direction, in particular horizontally.

[0017] In some embodiments, the locking hook includes a lower notch and the upper rail includes a retractable rim, the lower notch and the retractable rim being able to cooperate in a locking configuration.

[0018] In some embodiments, the locking hook includes a ratcheting tooth and the upper rail includes a ratcheting tooth, the ratcheting teeth being configured to cooperate in a locking configuration.

[0019] In some embodiments, the locking hook has a hook pin and a first bore suitable for receiving the hook pin, the locking guide having a first lower groove suitable for guiding the hook pin and a second upper groove, not aligned with the first lower groove, suitable for guiding a locking pin received in a second bore of the locking hook.

[0020] Thus, the juxtaposition of simple components allows for a kinematic of the hook of lockdown.

[0021] In some embodiments, the locking guides are interspersed with the movable hook and the locking hook.

[0022] The guidance of the locking axis and that of the hook axis are thus optimized.

[0023] In some embodiments, the second upper groove is either a curved groove or a straight groove oblique to the first lower groove.

[0024] The kinematics of guidance by such grooves is simple, reliable, and reversible. Curved grooves, in particular, allow for smooth, jerk-free movement. By way of non-limiting example, the grooves can be slots.

[0025] In some embodiments, the movable hook has a bore for guiding the hook axis.

[0026] The upper hook assembly is thus a rigid assembly.

[0027] In some embodiments, the movable hook has a hole for guiding a safety pin and the locking hook has a top notch for housing the safety pin, the safety pin being arranged to prevent unlocking the locking hook.

[0028] The safety pin limits the angular travel of the locking hook. The choice of bore on the movable hook, to guide the hook pin, also allows locking between the hook notch and the safety pin.

[0029] In some embodiments, the bore is oblong in shape.

[0030] In some embodiments, the movable hook forms a yoke surrounding the locking hook.

[0031] In some embodiments, the locking hook is in two parts, the movable hook being disposed between the two parts.

[0032] In some embodiments the upper hook assembly includes two locking guides.

[0033] In some embodiments, the locking guide is interposed between the movable hook and the locking hook.

[0034] In some embodiments, the upper hook assembly includes a locking hook return element in the release configuration.

[0035] In some embodiments, the return element is a compression spring attached to the locking hook or housed in a chamber of the locking hook.

[0036] This spring allows the locking hook to be moved apart to release the edge of the upper rail, when the stresses on the locking hook are reduced allowing the locking hook to leave the locking configuration to take the release configuration.

[0037] In certain embodiments, the adjustment means comprise a nut that can be stopped axially by a nut support and arranged to control the rotation of a threaded shaft that is able to cooperate with a tapping that includes the movable hook to move it in translation.

[0038] Thus, the adjustment means are both robust and inexpensive, allowing for fine and reproducible adjustment.

[0039] In certain embodiments, the rear panel rail is adapted to be movable angularly and in translation to allow the insertion or extraction of the upper hook assembly into or from the upper rail channel in order to allow the installation or removal of the panel.

[0040] Here again, the arrangement facilitates installation and removal. The translation allows the upper hook assembly to be inserted or removed from the upper rail channel, and the rotation allows the lower support to be inserted or removed from the lower rail.

[0041] In some embodiments, the second part comprises a lower support assembly, which includes the lower support and a lower vertical blocker fixed by a screw to the lower support and having an inclined surface arranged to cooperate with a complementary inclined surface which includes the lower support to form with it an adjustable wedge arranged to be held by pressure in a profile of the rear panel rail.

[0042] The lower support assembly is thus rigid, and can be positioned at will on the rear panel rail, in which it is firmly held by the expanding corner effect.

[0043] In certain embodiments, the lower support has, on the side opposite the rear panel rail, a stop arranged to cooperate in support with the lower rail, in a mounted and assembled position of the second part on the first part.

[0044] The pivoting of the panel is facilitated, and the stop is an anti-tipping safety feature and makes it possible to reduce, or even eliminate, noises related to vibrations of the panel subjected in particular to wind.

[0045] In some embodiments, the upper hook assembly includes a locking indicator.

[0046] The locking indicator is a visual indicator.

[0047] By way of non-limiting example, the locking indicator is a perforation, a visual mark that is visible when the system is in the locked configuration. This locking indicator allows verification that the system is indeed in the locked configuration.

[0048] In certain embodiments, the rear panel rail has, at its lower end, a lower safety hook arranged to support the weight of said panel, and / or, at its upper end, an upper safety hook arranged to prevent the panel from tipping over.

[0049] Thus, safety during operation is ensured, as well as safety on the installation or removal site. This arrangement allows the panel to be fixed to rails after installation. of panels already installed and pre-positioned on the rails. It also offers safety during handling and reduces the stress on the panel fixing methods to the panel rails.

[0050] In some embodiments, the means for fixing the panel to the panel rail include at least one interface seal or at least one adhesive film.

[0051] Thus, the use of mechanical fixing means is avoided which, in addition to their cost, may prove unsuitable with panels, particularly those with glazing, of low thickness.

[0052] In some embodiments, the panel is a photovoltaic panel, or a reflective glazing panel, or a panel comprising light diffusion or display means, or an insulation panel, or a forced air circulation panel.

[0053] The invention is thus versatile, and suitable for installing any type of panel.

[0054] The invention further relates to a building comprising a cladding according to the invention and a panel, said panel being a photovoltaic panel, or a reflective glazing panel, or a panel comprising light diffusion or display means, or an insulation panel, or a forced air circulation panel.

[0055] The invention further relates to a method for installing a cladding according to the invention on a building defining a plan, comprising the following steps: a step of obtaining a cladding according to the invention; a step of fixing the lower rail and the upper rail mounted parallel to each other on the building; a step of fixing the lower support and the upper hook assembly on each rear panel rail through the adjustment translation guide means; a step of separating the upper hook assembly and the lower support by acting on the adjustment means; a step of inserting each lower hook assembly into the channel of the lower rail for temporary support; a step of adjusting the position of the upper hook assembly of each rear panel rail, so that its locking hook fits into the channel of the upper rail;a step of fixing the upper hook assembly of each rear panel rail by pinching it onto the upper rail; a step of adjusting the position of the rear panel rail in the vertical direction.

[0056] The building is arranged on a surface defining a vertical direction along the Earth's gravitational field, a longitudinal direction perpendicular to the vertical direction, the vertical and longitudinal directions forming a plane parallel to the plane of the building, and a transverse direction perpendicular to the vertical and longitudinal directions. The direction of the upper and lower rails is along the longitudinal direction.

[0057] This makes it easy to adapt to the building's layout and to optimize the fixing methods for each panel. It is possible to choose to install the panel directly, equipped with its panel rail(s). This greatly simplifies site organization.

[0058] In particular, when installing the panel, the panel and therefore the rear panel rail can be assembled simultaneously on the upper and lower rails, i.e. the rear panel rail is inserted parallel to the plane formed by the upper and lower rails.

[0059] In some embodiments, the method includes a step of adjusting the position of each rear panel rail along the upper and lower rails after the introduction step.

[0060] The position adjustment is along the longitudinal direction. Brief description of the drawings

[0094] The present invention represents an improvement of prior designs for cladding a building facade with panels, in particular BIPV panels. In each of these designs, the mounting system is equipped with panel rails which are fixed, in particular glued, to the panel; on each panel rail there are two hook assemblies, one lower, the other upper, which can be adapted to the position of the rails, which are fixed to the building structure; and the mounting system is equipped with a fastening system accessible from one side of the panel; this fastening makes it possible to fix the panel to the rail and to prevent the panel from moving after installation.

[0095] The invention relates to a modifiable fastening system with at least two fasteners per rear panel rail, the upper one serving to lock the system (the upper fastener can be moved up and down by rotating the leveling system, which also locks the system in place). The system is applicable to both portrait and landscape orientations and to modules of all special shapes in addition to standard rectangular modules. The fastening is achieved by blocking one of the upper hooks with a plate that is raised and screwed in from the side. A spring is attached to the upper clamp to hold it open by default, and with a turn of the screw and the weight of the system, it locks in place. It can be moved vertically using the leveling system and locked in place.

[0096] In addition, there is an additional locking mechanism to prevent vertical movement of the panels once they are in the locked position under the panel's own weight, advantageously with an additional verification of the locking by means of a color code which ensures that the system is properly locked.

[0097] The system also allows horizontal movement of the panels on the rails in the unlocked position, i.e. in the release configuration.

[0098] The device according to the invention is a standard solution for photovoltaic panels (it can also be used for any other type of cladding, for example, glass, wood, metal, composite panel, board material, or other). It is also possible to adapt different panel shapes by placing the mechanical supports at strategic locations to hold the panels in place and prevent any failure of the system's attachment.

[0099] Thus, more particularly, and as can be seen in the figures, the invention relates to a cladding 1000 of a building 2000. This cladding 1000 comprises at least one structure 100 for fixing at least one panel 22 adjustable in position on the structure 100.

[0100] The figures refer to a reference trihedron XYZ, with a first direction Z designated vertical, a second direction Y designated longitudinal, perpendicular to the first direction Z, and a third direction X designated transverse, perpendicular to both the first direction Z and the second direction Y. While the invention is illustrated in the specific, non-limiting case where the first direction Z corresponds to that of the gravitational field of the mounting location, it is also applicable to the mounting of panels 22 with a slight inclination. According to the invention, the panel 22 is adjustable vertically along the first vertical direction Z, and longitudinally along the second longitudinal direction Y.

[0101] As seen in [Fig.1], the structure 100 comprises a first load-bearing part 200, which is arranged to be fixed to the building 2000, and a second part 300 which is arranged to be removably fixed to the first part 200.

[0102] The first part 200 comprises at least two mounting rails, which are mounted parallel and spaced apart, according to a predefined spacing: a lower rail 201A is arranged to be mounted closer to the ground than an upper rail 201B. Each rail, lower 201A or upper 201B, detailed in particular in [Fig.22] in an advantageous embodiment as a profile, comprises at least one part with an open hollow profile forming a channel, the open hollow profile being arranged to receive a lower support 2 of the second part 300. The channel may have an opening arranged to be turned upwards, i.e. towards the side opposite the ground.

[0103] The lower rail 201A and the upper rail 201B are fixed to the building 2000 by traditional means of fastening, known to those skilled in the art; advantageously, These fixing means do not protrude inside the cable tray, for example, by using countersunk screws cooperating with chamfered holes in the rail, or protrude only slightly, with flat-head screws 101, or similar, as shown in the figures. Most particularly and advantageously, the lower rail 201A and the upper rail 201B are identical, which simplifies handling.

[0104] By convention, the longitudinal direction Y is here called the direction along which the rails 201A and 20IB extend.

[0105] The second part 300 comprises at least one rear panel rail 1, which is arranged to support at least one panel 22, either directly or through fastening means. The number of rear panel rails 1 depends on the mass and dimensions of the panel 22 to be supported. The example in [Fig. 16] comprises two rear panel rails 1 mounted parallel to each other, along the vertical direction Z.

[0106] According to the invention, the rear panel rail 1 carries an upper hook assembly 30 comprising a locking hook 9 arranged to cooperate by pinching with the upper rail 201B. The upper hook assembly 30 and the rear panel rail 1 have means for translational guidance and adjustment. The upper hook assembly 30 is able to be movable in translation relative to the rear panel rail 1. The upper hook assembly 30 includes a movable hook 8 able to be movable in translation along the vertical direction Z along the rear panel rail 1 under the action of the adjustment means for bearing against the upper rail 201B and for vertical adjustment of the rear panel rail 1 relative to the building 2000. The locking hook 9 is able to be movable, under the action of the adjustment means, in rotation and / or translation relative to the movable hook 8.And the upper hook assembly 30 includes locking guides 12 having guide grooves cooperating with both the movable hook 8 and the locking hook 9 to control a kinematic movement of the locking hook 9 apart or together with the upper rail 201B to release or lock it respectively.

[0107] The locking hook 9 has a hook pin 11 and a first bore 91 suitable for receiving the hook pin 11. And each locking guide 12 has a first lower oblong groove 141 in which the hook pin 11 is suitable for movement and a second upper oblong groove 142 not aligned with the first lower oblong groove 141 and which is suitable for receiving a locking pin 13 guided in a second bore 92 of the locking hook 9.

[0108] The rear panel rail 1 is thus movable along a longitudinal direction Y along the lower rail 201 A, and carries a lower support 2 arranged to cooperate with the groove of the lower rail 201 A. locking hook

[0109] The upper hook assembly 30 is movable in translation relative to the rear panel rail 1, and therefore relative to the lower support 2, thanks to the adjustment means of the second part 300. These adjustment means are accessible to the user, here in the upper part of the rear panel rail 1, preferably flush with the upper end of the panel 22. These adjustment means include a translation means operable by a user, and cooperating with a movable hook solution to move it in translation.

[0110] The upper hook assembly 30 is movable from an insertion position to a holding position in vertical support of the rear panel rail 1 relative to the gravity field. In this insertion position, the distance between the lower support 2 and the upper hook assembly 30 is greater than the gap between the lower rails 201A and upper rails 201B, and the lower support 2 is insertable into the channel of the lower rail 201A; in this insertion position, the rear panel rail 1 is free angularly and in translation relative to the building 2000.

[0111] More particularly, the upper hook assembly 30 is arranged to, in the vertical support position of the rear panel rail 1, clamp the upper rail 201B by means of clamping means carried by the upper hook assembly 30.

[0112] These clamping means comprise a cooperation of elements for clamping the upper rail 201B. More particularly, the upper hook assembly 30 comprises a movable hook 8, detailed in [Fig. 17], which is movable in translation along the rear rail of panel 1 under the action of the adjustment means for its bearing on the upper rail 201B, and for the vertical adjustment of the rear rail of panel 1 relative to the building 2000 for its placement in a predefined position or in a position of alignment with other elements of the building 2000.

[0113] More particularly, the adjustment means comprise a threaded shaft 5, controlled by a nut 6 operable by the user and stopped axially by a nut support 4 detailed in [Fig.20], and cooperating with a tapped hole 85 of the movable hook 8, as seen in [Fig.28] and [Fig.29], to move it in translation.

[0114] In embodiments of [Fig. 28] and [Fig. 29], the locking guides 12 each include a locking indicator, in particular a visual locking indicator. In embodiments of [Fig. 28] and [Fig. 29], the visual locking indicator is a hole 149. As shown in [Fig. 29], the hole 149 is visible only when the system is in the locked configuration, i.e., when the panel 22 is locked onto the building 2000. In the release configuration, the hole 149 is not visible. It is hidden by the movable hook 8.

[0115] More particularly, the upper hook assembly 30 includes locking means, which are arranged to press the upper rail 201B and the rear panel rail 1 against each other.

[0116] More particularly, these immobilizing means include a locking hook 9, detailed in [Fig. 18], which is arranged to, in a locked holding position of the rear panel rail 1, immobilize the rear panel rail 1 on the upper rail 201B in all directions, and to, in an unlocked holding position, permit a translational movement of the upper hook assembly 30 along the direction of the upper rail 201B, i.e. the longitudinal direction Y along which this upper rail 201B extends, to permit a lateral adjustment of the position of the panel 22.

[0117] Advantageously, the immobilizing means comprise a locking hook 9 having a first bore 91 in which the hook pin 11 is received, also guided in two aligned recesses 82 of the movable hook 8, which are preferably oblong grooves allowing a small stroke, on the order of 2 mm for example. This locking hook 9 is movable in rotation and / or translation relative to the movable hook 8, in an opening / closing kinematics which is controlled by locking guides 12, detailed in [Fig. 19], which are interposed between the movable hook 8 forming an external yoke and the locking hook 9 disposed between these locking guides 12.The locking hook 9 closes and locks by the simultaneous action of the threaded rod 5 and the locking guides 12 when the latter come into contact with the upper surface of the upper rail 201B, aided by the weight of the rear panel rail 1 and the panel 22.

[0118] The movable hook 8 thus comprises a U-shaped profile bracket, in which the locking hook 9 is positioned, separated from the movable hook 8 by a locking guide 12 on each side. The two arms 81 of the bracket have aligned recesses 82, receiving the hook axis 11, which constitutes the axis of the locking hook 9, and around which this locking hook 9 can pivot. The movable hook 8 has a guide surface 83 for its guidance in the rear panel rail 1, and, in a particular embodiment, a bearing notch 84 on the upper rail 201B.

[0119] The assembly of the movable hook 8, the locking guides 12, and the locking hook 9 is made with minimal functional clearance to prevent any Y-axis movement of the locking hook 9 relative to the movable hook 8. The two locking guides 12 are identical. Preferably, the hook axis 11 and the locking axis 13 are both mounted with an interference fit, either with the movable hook 8 or with the locking hook 9. It is understood that the combination of the directions of the oblong grooves defines a movement of the locking hook 9 combining translation and rotation. This first variant is very robust and particularly well-suited for supporting heavy panels.

[0120] The user begins by fully separating the upper hook assembly 30 and the lower support 2, pre-positioning the lower support 2 in the groove of the lower rail 201 A, and then tilting the rear panel rail 1 towards the upper rail 20IB. In this starting position, the hook pin 11 and the locking pin 13 are in the upper part of the corresponding grooves, i.e., opposite the lower support 2. Then, by rotating the threaded rod 5 with the help of the nut 6, which is in particular equipped with a hexagonal head or similar for accepting a very thin open-end wrench, the user controls the movement of bringing the upper hook assembly 30 and the lower support 2 together until the upper hook assembly 30 rests on the upper rail 201B.During this approach maneuver, the hook pin 11 and the locking pin 13 move into the lower part of the corresponding grooves, i.e., on the side of the lower support 2, which controls the spacing of the locking hook 9 relative to the plane of the rear panel rail 1. It is then possible to move the rear panel rail 1, still supported at its lower end in the lower rail 201A, in the longitudinal direction Y, to adjust its position. Continuing the movement of the threaded rod 5, still in the same direction, has the simultaneous effect of folding the locking hook 9 onto the upper rail 201B, and of moving the lower support 2 away from the bottom of the lower rail 201A, by raising the lower support 2 in the vertical direction Z, which allows the position of the rear panel rail 1 relative to the lower rail 201A and the upper rail 201B, in the vertical direction Z.

[0121] More specifically, the upper hook assembly 30 comprises, in both the first and second variants, at least one spring 10, which is attached to the locking hook 9, particularly at a recess 99, and which tends to keep it open by default: this spring 10 works in repulsion, except when it is installed on the rail, the locking hook 9 is open. The locking hook 9 closes and locks by the simultaneous action of the threaded rod 5 and the oblong locking guides 12 when they come into contact with the upper face of the upper rail 201B (aided by the weight of the panel rail, or of the rear panel rail 1 and the panel 22 when the latter is pre-mounted on the rear panel rail 1). The upper hook assembly 30 is then clamped onto the upper rail 20IB.

[0122] The movable hook 8 forms an outer flange surrounding the locking hook 9 and has two aligned holes 87 for guiding a safety pin 7 arranged to prevent the locking hook 9 from falling. The locking hook 9 has an upper notch 97 for housing the safety pin 7. Indeed, the locking hook 9 has a natural tendency to open (due to the spring 10): if the panel is lifted by force, there is a risk of the hook opening and the system being released. Hence the addition of this safety pin 7 and this upper notch 97, which, when the movable hook 8 is in contact with the rail and the hook is closed, prevents The locking hook 9 is prevented from opening; this is true as long as the panel is not removed. It is therefore an inexpensive and very useful safety feature.

[0123] In reverse operation, the system is unlocked by manipulating the threaded rod 5 until the lower support 2 touches the lower rail 201A. The weight of the assembly is then no longer supported by the upper part but by the lower rail 201A. If the operation is continued, the locking hook 9 is released from the upper rail 201B, pushed by the spring 10 and the locking guides 12. The movable hook 8 and the locking hook 9 can then be released above the upper rail 201B, allowing the panel to be tilted for safe removal.

[0124] More particularly, between the insertion position and the vertical support holding position, the rear panel rail 1 is angularly and translationally movable, to allow the insertion or extraction of the upper hook assembly 30 into or from the upper rail 201B channel, in order to allow the installation or removal of a panel 22.

[0125] More specifically, at least the upper rail 201B has internally, at its upper part furthest from its support on the building 2000, a retractable lip 190, which is directed towards the building 2000. And the locking hook 9 and the movable hook 8 are arranged so as, in the locked holding position of the rear panel rail 1, to immobilize the retractable lip 190 of the upper rail 20IB, and, in an intermediate mounting position, to allow the retractable lip 190 to be released to permit the insertion or extraction of the upper hook assembly 30 into or from the channel of the upper rail 201B, in order to allow the installation or removal of a panel 22. For this purpose, the locking hook 9 advantageously has a lower notch 93 provided for immobilizing this retractable lip 190.

[0126] More particularly, the second part 300 comprises a lower support assembly, which includes the lower support 2 and a lower vertical blocker 3 fixed by a screw 20 to the lower support 2 and having an inclined surface 38 arranged to cooperate with a complementary inclined surface 28 which includes the lower support 2 to form with it an adjustable wedge arranged to be held by pressure in a profile of the rear panel rail 1. The adjustment can be adapted during the installation of the panel, since the lower support 2 and the lower vertical blocker 3 slide in the rear panel rail 1. No pre-drilling for positioning is necessary.

[0127] More particularly, and without limitation, the lower support 2 further comprises, on the side opposite the rear panel rail 1, a stop 29 which is arranged to cooperate in support with the lower rail 201A, in the mounted and assembled position of the second part 300 on the first part 200, in which the lower part The substantially cylindrical 25 rests on a side wall of the lower rail 201 A. This arrangement allows, with an appropriate dimensioning of the lower support 21 in relation to the calibrated rail 1, to have a lower support without play in this mounted and assembled position, while the upper hook assembly 30 is also firmly clamped on the upper rail 201B, which prevents vibrations and preserves the structure 100 and the panel 22 that it supports.

[0128] More specifically, the rear panel rail 1 has, at its end closest to the ground, a lower safety hook 15 arranged to support the weight of the panel 22. This ensures a secure fastening capable of supporting the mass of the panel 22, and the stop provides an anti-tipping safety feature. Or / and the rear panel rail 1 has, at its end furthest from the ground, an upper safety hook 14 arranged to prevent the panel 22 from tipping.

[0129] More particularly, and not limitingly, the means for fixing the panel 22 to the rear rail of panel 1 include at least one interface seal 16 or at least one adhesive film 17. The panel 22 can also be fixed by conventional mechanical means, screws, slides, profiles or the like, or by a combination of adhesive means and mechanical means.

[0130] Advantageously, the guidance of the nut 6 in the upper part of the rear panel rail 1 is secured to ensure that only rotation around the vertical axis Z is possible.

[0131] In an advantageous embodiment, the rear panel rail 1, detailed in [Fig.21], is a hollow profile, and the nut support 4 has a shape complementary to the inner profile of this profile, into which it is threaded, it is therefore blocked in the longitudinal Y and transverse X directions by the shape of the rear panel rail 1. The nut support 4 is blocked in a unique position along the vertical Z axis, in particular by front screws, once the pre-assembly of the system has been carried out.

[0132] In another particular embodiment, to secure the position adjustment made, the upper end of the rear panel rail 1 has a latch, movable in the longitudinal direction Y, to immobilize the locking system, and in particular to prevent the rotation of the nut 6 once the rear panel rail 1 and the panel 22 are adjusted in position.

[0133] More specifically, panel 22 is a photovoltaic panel, or a reflective glazing panel, or a panel incorporating light diffusion or display means, or an insulation panel, or a forced air circulation panel.

[0134] The invention also relates to a building 2000 comprising at least one such cladding 1000.

[0135] The invention further relates to a method of installing such a cladding 1000 on a building 2000.

[0136] According to the invention, the process comprises the following steps: - a step of obtaining El of the cladding 1000, of a lower rail 201A and of an upper rail 201B; we have previously determined the geometry of the structure 100, the spacing between the lower rail 201A and the upper rail 201B, and the number and position of the panel rails 3 in relation to the panel 22; - a fixing step E2 on the building 2000 of the lower rail 201A and the upper rail 201B, parallel to each other along the second direction Y, which in a usual but not limiting variant may coincide with the horizontal of the location of the building 2000, the lower rail 201A mounted closest to the ground of the location of the building 2000, with the openings turned towards the side opposite the ground; - a fixing step E3 on each rear panel rail 1 of the lower support 2 and of the upper hook assembly 30 through the translational guide means and the adjustment means; - a spacing step E4 of the upper hook assembly 30 and the lower support 2 by action on the adjustment means - an introduction step E5 of each lower support 2 into the channel of the lower rail 201A for temporary support along the vertical direction Z, and adjustment of the longitudinal position of each rear panel rail 1 along the longitudinal direction Y; - an adjustment step E6 of the position of the upper hook assembly 30 of each rear panel rail 1, so that its locking hook 9 fits into the channel of the upper rail 201B; - a fixing step E7 of the upper hook assembly 30 of each rear panel rail 1 by pinching on the upper rail 201B; - an adjustment step E8 of the position of the rear rail of panel 1 according to the vertical direction Z.

[0137] The panel 22 is finally fixed onto the rear rail of panel 1, either directly or through fixing means, during the fixing step E3 or during, or after, the adjustment step E8.

[0138] More particularly, for each panel 22 a selection step selects, according to its size and mass, either a first alternative for handling the panel 22 equipped with each rear rail of panel 1, fixed together beforehand, or a second alternative for positioning each rear rail of panel 1 relative to the lower rail 201A and the upper rail 201B before fixing the panel 22 on each rear rail of panel 1.

[0139] For each rear panel rail 1, an insertion step consists of inserting its lower support 2 into the groove of the lower rail 201A, and a folding step consists of folding the rear panel rail 1 angularly towards the upper rail 201B in support of the lower rail 201 A, a maneuvering step consists of controlling the adjustment means to bring the upper hook assembly 30 into support of the upper rail 201B, and to clamp the upper rail 201B by clamping means carried by the upper hook assembly.

[0140] In a first alternative, a release step allows the clamping means to be released to permit a longitudinal adjustment along the longitudinal direction Y of the position of the panel 22 relative to the lower rail 201A and the upper rail 201B and along the direction of the lower rail 201A and the upper rail 20IB, before locking the clamping means and proceeding to a vertical adjustment of the position of the panel 22 in distance relative to the lower rail 201A and the upper rail 201B by continuing the action on the adjustment means and loss of the lower support of the lower support 2 in the channel of the lower rail 201 A.

[0141] Or, in a second alternative, a fixing step consists of fixing the panel 22 on each rear rail of panel 1, before a step of releasing the clamping means to allow a longitudinal adjustment along the longitudinal direction Y of the position of the panel 22 relative to the lower rail 201A and the upper rail 201B and along the direction of the lower rail 201A and the upper rail 20IB, before locking the clamping means and proceeding to a vertical adjustment of the position of the panel 22 in distance relative to the lower rail 201A and the upper rail 201B by continuing the action on the adjustment means and loss of the lower support of the lower support 2 in the channel of the lower rail 201A.

[0142] [Fig. 10] to [Fig. 14] illustrate the assembly and disassembly kinematics of the cladding in relation to the building.

[0143] [Fig. 10] illustrates, in three drawings 01, 02, 03, the presentation of the ready-to-mount panel (as seen in [Fig. 17]) relative to the building structure. Drawing 01 and its detail 01A show the oblique presentation with the lower hook assembly 2 inserted into the lower rail 201A: the BIPV system is tilted to allow the insertion of part 10 into the fixed lower rail. Drawing 02 and its detail 02B show the tilting of the assembly in the plane of the building rails: the lower hook assembly 2 comes into contact (A1) with the lower rail 201A fixed to the wall. Drawing 03 shows the verticalization of the panel until it contacts the upper rail 201B of the building: the BIPV system is brought into a vertical position until it comes into contact (A2) with the upper rail 201B fixed to the wall.

[0144] [Fig. 11] illustrates, in two drawings 04 and 05, the beginning of the locking kinematics of the upper hook assembly on the upper rail of the building. Drawing 04 and its detail 04C show the descent of the upper hook assembly onto the upper rail of the building: by rotating the nut 6 and the threaded rod 5, the upper hook assembly 30 descends in a Z-shape until it makes contact (A3) with the rail upper 201B fixed to the wall. Drawing 05 and its detail 05D show the angular movement of the locking hook 9 with bypassing the edge 190 of the upper rail 201B, then its closing on the upper rail 201B by compressing the spring 10: by continuing the rotation of the nut 6 and the threaded rod 5, the locking hook 9 closes (A4) on the upper rail 201B fixed to the wall, by action of the locking guides 12, compressing the spring 10.

[0145] [Fig. 12] illustrates, in two drawings 06 and 07, the continuation of the locking kinematics of the upper hook assembly 30 on the upper rail 201B of the building. Drawing 06 and its detail 06E show the bearing of the hook axis 11 on the lowest point of the lower slot 82 of the movable hook 8, and the locking of the locking hook 9: by continuing the rotation of the nut 6 and the threaded rod 5, the hook axis 11 reaches the lowest point (A5) of the lower slot 82 and locks the locking hook 9.Drawing 07 and its detail 07F show the height adjustment of panel 22 to the desired height relative to the building: by continuing the rotation of nut 6 and threaded rod 5, the BIPV system assembly rises to the desired height (A6) (with a stroke in particular, but not limited to, of the order of 10mm); it is noted that, when the lower hook assembly 2 is no longer in contact with the lower rail 201A fixed to the wall, the BIPV system is considered to be completely locked and enters the adjustment phase.

[0146] [Fig. 13] illustrates, in two drawings 08 and 09, the beginning of the unlocking kinematics during a panel removal operation. Drawing 08 and its detail 08H show the descent of the panel until the lower hook assembly 2 contacts the lower rail 21A of the building. The initial unlocking of the locking hook 9 occurs during this descent: by reverse rotation of the nut 6 and the threaded rod 5, the entire BIPV system descends to make contact (A7) with the lower rail 201 fixed to the wall. The movable hook 8 continues to rise, placing the hook axis 11 on the lowest point (A8) of the opening 82. This action unlocks the locking hook 9. Drawing 09 and its detail 091 show the complete unlocking of the locking hook 9: with this locking hook 9 (A9), the reverse rotation of the nut 6 and the threaded rod 5 continues.

[0147] [Fig. 14] illustrates, in three drawings 10, 11, 12, the end of the unlocking kinematics. Drawing 10 and its detail 10J show the disengagement of the upper hook assembly 30 from the upper rail 201B to allow the panel to be removed: the reverse rotation of the nut 6 and the threaded rod 5 continues until there is sufficient space (A9) to remove the BIPV system. Drawing 11 shows the oblique tilting of the panel, by the opposite action to that of drawing 02 of [Fig. 10]. Drawing 12 shows the extraction of the panel by lifting for the extraction of the lower hook assembly 2 of the lower rail 201, by the opposite action of that of drawing 01 of [Fig. 10].

[0148] In summary, the building cladding according to the invention is a new mounting system for facades, particularly for cladding with BIPV photovoltaic panels, and is much easier to install than systems available on the market. Furthermore, it is equipped with a single-point fixing system and an easily accessible leveling system compared to other systems available on the market (in some cases, fixing and leveling are absent from systems available on the market).

[0149] In addition, the position of the fixings can be adapted to the location of the fixing on the facade.

[0150] In summary, the designs are based on a glued mounting system for the rear bar, in which the rear bars are fixed to a horizontal mounting rail.

[0151] The invention makes it possible to achieve a level of stability much higher than current competing systems on the market.

[0152] The leveling system is accessible at the horizontal joints.

[0153] The locking system is based on a simple and effective clamping mechanism.

[0154] Installation is much faster and easier than standard systems.

[0155] There is no need to manage sets of spare parts, as everything is already integrated into the rear rail system and the various hooks and adjustment systems; it is truly a ready-to-mount device.

[0156] The installation method ensures the safety of the installation personnel, thanks to prior support on the lower rail, and also guarantees the integrity of the panels, which can be handled without risk. The possibility of easy flat adjustment in two dimensions, namely vertical and horizontal, allows for perfect alignment of a panel with other panels or according to specific architectural elements of the building.

[0157] Access to the adjustment means requires only a space of a few millimeters, sufficient for the insertion and manipulation of a tool such as a flat wrench, which makes it possible to guard against the insertion of foreign bodies, in particular insects, under the panel.

[0158] The invention is also usable for panels mounted slightly obliquely with respect to the field of gravity, either with rails slightly oblique with respect to the horizontal, or with a panel plane slightly oblique with respect to the vertical of the place with for example a sloping facade.

[0159] The invention also allows for easy and secure assembly of panels of a shape other than rectangular and allows for good adaptation to the architectural design of the building.

[0160] In some embodiments, the locking indicator may be carried by an element other than the locking guide 12.

[0161] By way of non-limiting example, the locking indicator may be carried by the locking hook 9, in particular when the locking hook 9 is in two parts.

[0162] Although the present description has been made with reference to a specific embodiment, it is evident that various modifications and changes can be made to these examples without departing from the general scope of the invention as defined by the claims. Furthermore, individual features of the various embodiments mentioned can be combined in additional embodiments. Therefore, the description and drawings should be considered in an illustrative rather than restrictive sense.
