Description

The present invention relates to an improved device for ensuring the fixing and sealing between the panels (cladding) commonly used to cover the facades of various constructions in order, on the one hand, to ensure the finish and, on the other hand, to provide external thermal insulation.

One of the problems in the field of construction is that of finishing facades as well as thermal insulation.

One of the solutions proposed to date for solving this problem consists, after the walls have been made, of bringing a covering consisting of elementary panels, juxtaposed to each other and behind which an insulation material (wool) is placed on the facade. glass for example).

Such panels, commonly designated by the expression "cladding can be based on various materials such as slate, fiber cement stone, laminate ...

In general, as is apparent in particular from FR-A-2 308 746, these panels are fixed to the wall by means of a system comprising brackets and the sealing between the panels is ensured, after assembly, using joint covers. The main drawbacks of the solutions proposed to date relate, on the one hand, to the assembly proper which is difficult to carry out and, on the other hand, to the fact that the added seals can be easily removed.

Now we have found, and this is what is the subject of the present invention, a solution which not only makes it easier to assemble the panels, but also makes it possible to ensure the seal between said panels without having to report exterior seals.

• les moyens fixés sur la face arrière des panneaux élémentaires destinés à former le revêtement sont constitués d'au moins deux glissières horizontales espacées l'une de l'autre ;
• les systèmes à équerre fixés à la paroi et destinés à assurer le maintien desdits panneaux sont constitués d'éléments déplaçables les uns par rapport aux autres et permettent de réaliser un réglage horizontal parallèlement et perpendiculairement à la paroi, ces éléments supportant sùr leur face avant un ensemble formant griffe susceptible d'être introduit à l'intérieur des glissières de deux panneaux consécutifs, ledit ensemble étant muni d'un joint vertical pouvant être déplacé mécaniquement après montage pour le rapprocher contre l'arrière des panneaux, de part et d'autre de la zone de jonction entre deux panneaux, ce qui permet d'assurer à la fois l'étanchéité entre les panneaux élémentaires ainsi que le blocage desdits panneaux sur les équerres de maintien et de positionnement.

In general, the device according to the invention making it possible to ensure both the fixing and the sealing of panels attached to the facades of various constructions and comprising means fixed on the rear face of each panel and which are adaptable on square systems fixed in turn against the facade or wall to be covered is characterized by the fact that:

• the means fixed on the rear face of the elementary panels intended to form the covering consist of at least two horizontal slides spaced from one another;
• the square systems fixed to the wall and intended to ensure the maintenance of said panels are made up of elements that can be moved relative to each other and allow horizontal adjustment to be made parallel and perpendicular to the wall, these elements supporting on their front face a assembly forming a claw capable of being introduced inside the runners of two consecutive panels, said assembly being provided with a vertical seal which can be moved mechanically after assembly to bring it together against the rear of the panels, on either side of the junction zone between two panels, which ensures both the sealing between the elementary panels as well as the blocking of said panels on the retaining and positioning brackets.

• les glissières fixées à l'arrière des panneaux élémentaires se présentent sous la forme de profils en U, montés directement en usine,
• les équerres de positionnement et de maintien des plaques contre la paroi sont formées de deux parties élémentaires réglables l'une par rapport à l'autre,
• le système à griffe fixé aux extrémités desdites équerres est constitué par un profil métallique cintré supportant un bloc de même nature que les plaques de revêtement, ce profilé étant susceptible d'être introduit à l'intérieur des glissières et son maintien à l'extrémité des équerres étant assuré à l'aide d'un système à vis accessible de l'extérieur.

According to one form of implementation of the invention:

• the slides fixed to the rear of the elementary panels are in the form of U-shaped profiles, mounted directly at the factory,
• the brackets for positioning and holding the plates against the wall are formed of two elementary parts adjustable relative to each other,
• the claw system fixed to the ends of said brackets is constituted by a curved metal profile supporting a block of the same kind as the covering plates, this profile being able to be introduced inside the slides and its retention at the end of the brackets being secured using a screw system accessible from the outside.

Alternatively, the horizontal slides fixed to the rear of the elementary plates intended to form the covering are in the form of brackets, spaced from one another and between which are arranged, vertically, slightly recessed relative to the edge of the panel, additional vertical brackets. These horizontal and vertical brackets have regularly spaced along their length, lights. The connection is also obtained by means of a claw system capable of being introduced inside the lights of the vertical brackets of two consecutive panels. This variant makes it possible to obtain a perfect blocking of the panels as well as a possibility of adjustment in the vertical direction and a strengthening of the plate which prevents it from deforming.

If reference is made to the appended diagrams, the invention relates to an improvement in the production of a coating of facades by means of elementary panels fixed against said facade, spaced from the latter so as to preferably trap a layer of insulation. thermi ques.

The elementary panels capable of being used for the implementation of the invention may be based on any material commonly used for such an application, for example made from a laminated material. These plates may also have variable dimensions. For example, plates of 1 m x 1.50 m having a thickness of 6 mm could be used. Of course, this is not limiting and other dimensions of plates could be used without departing from the scope of the invention.

These plates are pre-cut in the factory and possibly coated with an exterior finishing layer, for example a plaster.

The appended figures illustrate two embodiments of a device allowing, in accordance with the invention, the fixing of elementary plates (1, 2) against a wall (3).

According to a first embodiment illustrated by Figures 1, 2 and 3, each of the plates (1, 2) has on its rear face, arranged horizontally, slides (4) at least two in number on the height, and constituted by U-shaped profiles fixed to the plates (1, 2) by means of bolts (5). The mounting of these slides (4) is carried out in the factory.

The fixing of the elementary panels thus formed against the facade (3) is carried out in accordance with the invention by means of an assembly making it possible, on the one hand to maintain the plates (1, 2) spaced from the facade (3) to interpose an insulating layer, formed for example of rigid panels of mineral wool fixed to structural work in a conventional manner and, on the other hand, ensuring the connection between the consecutive plates as well as the sealing between these plates.

This set comprises a system of brackets, formed of two elementary brackets (7, 8), one (7) being fixed against the wall (3) by means of screws (or equivalent) (9), lights (10) being advantageously provided to allow a transverse adjustment, the other (8) being fixed on the branch (11) of the bracket (7), preferably in an adjustable manner with respect to these branches, for example by providing a light (12 ) on this branch (11). The brackets (7, 8) therefore allow horizontal adjustment to be made parallel and perpendicular to the wall.

On the front part (13) of the bracket (8), is fixed a claw (6), in the shape of a U, projecting on either side of this bracket. This claw (6) supports an interior joint cover (14), which is based on a material similar to that of the plates (1, 2), having on its front face sealing strips (15), constituted for example foam adhesive strips. This seal (14) is fixed to a metal profile (16) by means of screws (17) in order to ensure the rigidity of the assembly. These joint elements (14) -profile (16) are mounted on the claw (8) and the part (13) of the bracket by means of a special screw (18) and a nut (19), this flanged screw , itself tapped in its center, receives another screw (21), controlled from the outside of the seal. This flanged screw is left-hand, allows, when the assembly is in place, to press the joint block against the rear of the panels (1, 2) (see Figure 3). The establishment of the elementary panels using the device according to the invention is carried out as follows.

First, the brackets (7, 8) are mounted against the wall and adjusted, the claw (6) having been removed.

The claw (6) is then put in place with the seal (14) which is kept completely loose (see FIG. 2). The end of the claw is then introduced inside the slides (4) provided at the rear of the panels and, after having adjusted the levels, the clamping nuts (19, 20) of the claws are blocked. The next plate is mounted on the other side and so on. The final fixing of the plates (1, 2) and the sealing between these plates is then carried out by tightening the joint block (14) by means of the screw system (21) which, as said previously, has a step to the left .

The second embodiment in accordance with the invention illustrated by FIG. 4, a figure in which the same references have been used to designate elements similar or equivalent to those of the example given above differs from this example essentially by the fact that the elementary plates (1, 2), intended to form the covering, comprise on their rear face not only horizontal slides (4) spaced from one another (only one of these slides being shown), but also additional vertical slides ( 4b) arranged between the horizontal slides (4) slightly set back relative to the lateral edges (22, 23) of the elementary plates (1, 2). In this embodiment, the claw system capable of being introduced inside the slides of two consecutive panels consists of a plate (6), projecting, capable of being introduced into the slots (24) of the vertical slides (4b).

The devices according to the invention described above make it possible to obtain perfect immobilization of the covering plates as well as a very good seal, the seals cannot be removed.

Compared to previous solutions, the devices according to the invention have numerous advantages in that all of the elements (plates and fixings) can be prepared in the factory and that only the simple adjustment and positioning operations are carried out on site.

Furthermore, it should be noted that in the variant which is the subject of FIG. 4, an additional horizontal seal (25) can be introduced between the panels proper (1, 2) and the vertical slides (4b).
