Definitions

• the present invention relates to building facade cladding using juxtaposed metal cladding panels.
• FR-2563262 thus describes a covering assembly comprising rectangular metal plates coating, having at their ends longitudinal folds for attachment to fastening lugs integral amounts fixed to the facade.
• BE1004142 teaches a cladding system with platelet-type elements, involving rigid, generally C-shaped profiled panels, fixed horizontally along the wall to be covered. Said plates are then fixed to the rods with hooks.
• DE10313649 discloses a facade cladding assembly comprising thin metal panels attached to rails. Fixings, however, allow some lateral play, useful when laying juxtaposed plates. This game can also take into account the thermal expansion. The panels are therefore not immobilized laterally. Note also that this device requires significant slots between juxtaposed plates, of the order of one centimeter.
• DE9004887 (Gebrauchsmuster) relates to a device for fixing wall covering plates. Each plate is pressed by at least one key on support profiles fixed to the wall. This system immobilizes the plates laterally, but allows a useful vertical displacement when replacing a plate. The thermal expansion and retraction or hygrometry of the elements of the device, as well as the vibrations induced by the wind, will cause more or less long term the disengagement of said key. Note also that this device requires large slots between adjacent plates, of the order of one centimeter. Unlike the prior art, the object of the invention is here primarily focused on obtaining an aesthetic effect, and less on waterproofing. Some protection of the facade against the weather remains desirable. This can be achieved by minimizing the gaps between adjacent plates.
• the desired aesthetic effect is essentially that of a flat and smooth skin based on elements of various shapes, without apparent repetitive structure based on strips or rectangular panels such as that presented by clapboard.
• the system must be able to withstand the variations of temperatures encountered outdoors.
• a solution is sought that simplifies the assembly of the individual elements. It is clear that the prior art cited above does not meet these criteria at all.
• the present invention achieves the desired result using a building facade cladding assembly, including rails (2, 2) attached to the facade and thin metal cladding panels. (1, 1 ', 1 ") juxtaposed and placed parallel to the facade, each panel being provided on its front side face of fastening elements (3, 3', 3") secured to said panel by non-through means, said fastening elements being provided for cooperating with said rails, characterized in that this co-operation defines, for each panel:
• the rails can advantageously be attached to the facade in a substantially horizontal direction, defining with respect to each panel an upper rail (2) and a lower rail (2 ').
• the sliding fastening points are then made using one or more fastening elements (3) located on the upper part of said panel, intended to co-operate with said upper rail, and one or more fasteners (3 ') located on the lower part of said panel, intended to co-operate with said lower rail.
• the co-operation between fastening elements (3) and the upper rail only allows sliding along said rail, while co-operation between the fastening elements (3 ') and the lower rail allows only a parallel movement to the facade.
• the fixing point without degree of freedom (3 ") is preferably obtained by locking on the upper rail of a sliding fastening element (3) This can be achieved by means of a fixed bracket, preferably by screwing, to said upper rail.
• top rail and bottom rail functions can be combined into a single rail.
• profile of the composite rail will include:
• a profile (4) having a horizontal opening directed towards the outside of said facade, provided with hooks (5, 5 ') retaining intended to close on horizontal protuberances (7, 7 ') provided in the fastening elements (3, 3 ");
• fastening elements (3, 3 ', 3 ") in an electrically insulating material.
• Thin metal panels means sheets having a thickness of less than 5 mm, for example 1 mm. There is no need to preform them.
• the system recommends the attachment of the panels along their upper edge, their lower edge can slide vertically over a distance of a few mm, ie enough to take the thermal expansion into account. As the panels are thus suspended, any risk of buckling, in particular during the implementation of particularly thin panels, is avoided.
• This arrangement also ensures easy installation: the lower fasteners of the panel are initially based on the vertical edge of the lower profile, the top of the panel is then pushed horizontally to the front, and clipped on the upper profile. This clipping causes a slight translation of the panel upwards, thus partially disengaging the vertical edge of the lower profile out of the slot at the lower fasteners. It is precisely this partial clearance that allows thermal expansion in the vertical direction.
• Thermal expansion in the horizontal direction is also guaranteed: the expansion propagates from the fixed attachment point which is preferably on the upper part of the panel considered.
• the other points of attachment both those on the upper part and those on the lower part, have the freedom to slide horizontally.
• the system allows, at least in a preferred implementation, the installation of the panels in an arbitrary order. This means that during assembly on site, it is possible to work upwards or downwards, in synchronism with the assembly or disassembly of a scaffolding.
• the use of a bucket elevator allows a quite arbitrary order of installation.
• any panel can be removed and replaced, without having to intervene on the adjacent panels.
• the fastening elements are preferably made of electrically insulating material. This facilitates the choice of metals compatible for rail and panel: the electrical contact between these elements is avoided and there is therefore no formation of an electrochemical couple that can induce accelerated corrosion.
• Figure 1 shows an overview of the system, illustrating the use of a single profile rail (2, 2 ') for the upper and lower connections of a panel.
• Figure 2a shows a type (3, 3 ") fastener normally used on the top of a panel
• Figure 2b shows a fastener (3 ') normally used on the bottom.
• a particular implementation uses pre-patinated zinc sheet sheets with a thickness of 1.5 mm (QUARTZ-ZINC ® ). These sheets are then cut using precision equipment, such as a digital cutting table. It is useful to limit the area of each panel thus obtained to less than 2 m 2 , this for the purpose of maneuverability during transportation and installation. The cuts are usefully arranged so that once assembled on the facade, the various panels completely cover the whole, while leaving thin expansion slots, of the order of 2 to 3 mm between the elements.
• the façade to be covered is provided with horizontal rails having a profile according to Figure 1. These rails are fixed with screws respecting a distance between rails allowing a correspondence between the upper and lower attachment points for a whole horizontal row. of panels.
