Description

The present invention relates to a system for fixing cladding panels on a building surface, a connecting piece, a cladding panel and a support piece intended for the implementation of this system, and a method of mounting of this fastening system.

Traditionally, cladding system fastening systems on a building surface include a counterframe consisting of a mesh of vertical uprights and horizontal cross members. This makes it possible to create a flat structure that corrects the unevenness of the surface to be dressed and on which the covering panels are mounted.

However, it can result from a failure of assembly of the backbone residual problems of flatness, only visible when all the cladding panels have already been mounted on the structure. If necessary, this requires a complete disassembly of the cladding panels and an intervention on the structure to regain flatness. It will be readily understood that the cladding of a surface with a traditional fastening system can be expensive in terms of manpower. In addition, in case of deterioration of one or more cladding panels, by accident or by vandalism, it is often necessary to disassemble all the cladding panels, because their system of attachment or socket, between them and / or on the structure, makes adjacent cladding panels interdependent in terms of assembly and disassembly. Also the present invention aims to overcome all or part of these disadvantages by proposing a system for fixing cladding panels on a surface to be clad a building, offering the possibility of mounting / disassembling the cladding panels independently of one of the other and offering the possibility of correcting punctually any flatness defects of the surface to be dressed, during the installation of cladding panels, and after the installation of cladding panels, without having to disassemble them all.

For this purpose, the subject of the present invention is a system for fixing cladding panels on a surface of a building, in particular a facade, wall, ceiling, roof or terrace, characterized in that the fixing system comprises a piece of support provided with a base to be fixed on the surface to be dressed, two covering panels, each covering panel having a first main face intended to be oriented towards the surface to be dressed and a second main face opposite to the first main face, a connecting piece intended to be connected to the support piece, adjusting means for adjusting the distance between the connecting piece and the base of the support piece, interlocking means of each panel of covering on the connecting piece, the interlocking means comprising, on one of the sides of each covering panel, a protruding portion extending from the first face ncipale, and, on the connecting piece, at least two housings separated by a separating member and intended to each receive the protruding portion of one of the two trim panels, the housing having a similar shape adapted to guide the insertion of each of the projecting portions in a same direction, so that the two separate covering panels can be nested independently of one another on the connecting piece via a similar interlocking movement guided by the cooperation of the projecting portion and the housing in which it is inserted, and means for immobilizing each covering panel on the connecting piece, the immobilizing means comprising, on each covering panel, a shoulder on the outside flank of their protruding portion, and a bearing surface arranged to abut against a corresponding abutment surface provided on the connecting piece. sound to stop the insertion of each of the protruding portions in the corresponding housing in a position in which the corresponding locking shoulder is at the height of the upper face of the separating member, and on the connecting piece, a locking member movably mounted on the upper face of the separating member between a first position in which the locking member cooperates with at least one of the locking shoulders to prevent withdrawal of the corresponding projecting portion out of the housing in which it is inserted, and a second position in which the locking member allows the withdrawal of at least one of the projecting portions out of the housing in which it is inserted. Thus, the fastening system according to the invention makes it possible to fit several covering panels independently of one another on the same connecting piece, given the distance between the housings causing a lack of contact between the panels, and in view of their similar shape, which requires the installation of the cladding panels in a same lateral movement oriented towards the connecting piece (no interference between two adjacent cladding panels during assembly or disassembly).

In addition, the locking member, located on the housing separator member, and therefore between the adjacent cladding panels fitted on the connecting piece, is accessible even when the adjacent cladding panels are fitted on the part. link ; therefore, the release of one of the cladding panels (for example to replace it because it is damaged), is not subject to disassembly of adjacent cladding panels. Finally, the adjustment means make it possible, by varying the distance between the connecting piece and the integral base of the surface to be dressed (thus the covering panels and the surface to be dressed), to correct the unevenness of this surface. surface, during the installation of the cladding panels, and even after, because it is sufficient to disassemble the corresponding cladding panel (which is possible in view of the independence of the adjacent cladding panels) to access the connecting piece and the support piece (thus to the adjustment means). It will also be noted that the connecting piece receives several dressing panels; thus the adjustment of its distance relative to the base simultaneously impacts the cladding panels fitted on the connecting piece. This is a guarantee of flatness in the sense that breaks in flatness between two adjacent panels due to an adjustment are avoided. According to one embodiment, the locking member corresponds to a rotatably mounted cam on the upper face of the separating member and shaped to co-operate simultaneously with the locking shoulders of two projecting portions inserted into the housings when the member blocking is rotated by a predetermined fraction of a turn to the second position.

Thus, the locking member makes it possible to block, or unblock, simultaneously, the two adjacent cladding panels. Advantageously, the cam comprises a lateral functional surface intended to bear, simultaneously, against a clamping surface located on the outer side of each projecting portion, when the locking member is pivoted by a predetermined fraction of a turn. to the second position, the distance between the clamping surfaces of the two trim panels nested on a separate housing of the connecting piece being smaller than the largest diameter of the cam, so that the rotation of the locking member to the second position causes a simultaneous tightening of the protruding portions of the two trim panels in the corresponding housing of the connecting piece.

According to one embodiment, the adjustment means comprise an oblong slot, located on the support piece or on the connecting piece, intended to receive a removable axle respectively attached to the connecting piece or to the support piece, and means for immobilizing the axis in the light. The axis can thus be translated into the oblong slot in an infinity of positions each defining a possible distance between the connecting piece and the base.

As can be seen in FIG. 1, the fixing system 1 comprises a support piece 10 provided with a base 11 intended to be fixed on the surface to be dressed, two covering panels 30, each covering panel 30 having a first main face 31 intended to be oriented towards the surface to be dressed and a second main face 32 opposite to the first main face 31, a connecting piece 50 intended to be connected to the support piece 10, adjusting means intended to adjust the distance between the connecting piece 50 and the base 11 of the support piece 10, the interlocking means of each covering panel 30 on the connecting piece 50, and means for immobilizing each panel 30 dressing on the connecting piece 50, the adjusting means, interlocking, and fixing being described in more detail below. As shown in particular in FIGS. 2 and 4, the interlocking means comprise, on one of the sides 37 of each covering panel 30, a protruding portion 33 extending from the first main face 31 Each protruding portion 33 may, for example, correspond to a return extending the full length of the side 37 of the corresponding trim panel 30. Furthermore, each projecting portion 33 may for example rise substantially perpendicularly to the first main face 31 of the corresponding panel 30 dressing. The interlocking means also comprise, on the connecting piece 50, at least two housings 51, for example grooves, separated by a separating member 52, for example a rib. The housings 51 are intended to each receive the portion 33 projecting from one of the two panels 30 dressing. The housings 51 have a similar shape adapted to guide the insertion of each of the portions 33 projecting in the same direction, so that the two separate panels 30 dressing can be nested independently of each other on the room 50 of connection via a lateral interlocking movement guided by the cooperation of the protruding portion 33 and the housing 51 in which it is inserted, for example in a direction substantially perpendicular to the second main face 32 or substantially perpendicular to the surface to dress. According to the examples visible in FIGS. 1 to 10, the housings 51 are grooves that are identical and substantially parallel, extending symmetrically on either side of the rib 52. The immobilizing means comprise, on each panel 30, cladding, a shoulder 34 of locking formed on the outer flank of their portion 33 projecting, and a bearing surface 36 arranged to abut against a surface 53 against counter-support provided on the connecting piece 50 to stopping the insertion of each of the portions 33 projecting into the corresponding housing 51 in a position in which the corresponding blocking shoulder 34 is at the height of the upper face 54 of the separating member 52. According to one possibility, each locking shoulder may extend over the entire length of the projecting portion 33. The immobilizing means also comprise, on the connecting piece 50, in addition to the counter-bearing surface 53, a locking member 55 mounted movably on the upper face 54 of the separating member 52, between a first position, visible in particular in Figure 2, wherein the locking member 55 cooperates with at least one of the shoulder 34 to prevent the locking portion 33 protruding corresponding from the housing 51 in which it is inserted, and a second position, visible in particular in Figure 7, wherein the locking member 55 allows the removal of at least one of the portions 33 projecting from the housing 51 in which it is inserted. According to one embodiment, visible in FIGS. 2 to 5 and in FIG. 7, the locking member 55 corresponds to a cam rotatably mounted on the upper face 54 of the separating member 52 and shaped to cooperate simultaneously with the shoulders 34 locking each of the portions 33 protrusions inserted into the grooves 51 when the locking member is rotated by a predetermined turn fraction, for example a quarter turn, to the first position. Thus, according to this embodiment, the locking member 55 makes it possible to block, or unblock, simultaneously, the two adjacent trim panels 30.

The upper face 54 of the separating member 52 may, for example, support two locking members 55, as illustrated in FIG. 2. This feature has the advantage of allowing the fitting of four covering panels 30 on one side. same piece 50 of connection. Advantageously, the cam here forming the blocking member 55 comprises a lateral functional surface 56 intended to bear, simultaneously, against a clamping surface 38 situated on the outer flank of each protruding portion 33, when the locking member 55 is rotated from the predetermined turn fraction to the second position. The distance separating the clamping surfaces 38 of the two cladding panels 30 fitted on the connecting piece 50 is smaller than the largest diameter D of the cam, so that the rotation of the locking member 55 towards the first position causes a simultaneous tightening portions 33 projecting from the two panels 30 dressing in the housing 51 of the part 50 connecting.

The bearing surface 36 of each protruding portion 33 may correspond to a second shoulder 39 intended to bear against an upper surface 57 of the locking member 55, the upper surface 57 of the locking member 55 corresponding to the surface 53 of counter-support of the connecting piece 50.

Thus, the second shoulder 39 and the locking shoulder 34 delimit between them a groove 40 in which is intended to engage the locking member 55 when it is moved to the first position, the bottom of this groove 40 corresponding at one of the clamping surfaces 38. Note that the second shoulder 39 has a height (from the bottom of the groove 40) greater than that of the shoulder 34 for locking the insertion of the latter in the housing 51 of the part 50 while connecting the second shoulder 39 stops this insertion when the blocking shoulder 34 reaches the height of the upper face 54 of the member 52 of separation.

The bearing surface 36 of each protruding portion 33 may also correspond to an end wall 41 of each protruding portion 33, as can be seen in FIG. 7 or 8, the counter-bearing surface 53 of the part 50 of the connection corresponding to the bottom wall 58 of each housing 51. The bearing surface 36 of each protruding portion 33 may also correspond to a portion 47 of the first main face 31, the counter-bearing surface 54 of FIG. the connecting piece 50 corresponding to the upper surface 59 of a flank portion 60 bordering each housing 51.

The axis 62 can thus be translated into the oblong slot 12 according to a plurality of positions defining each possible distance between the connecting piece 50 and the base 11. Optionally, as can be seen in FIG. 3, the adjusting means 25 may comprise a second oblong slot 12, substantially parallel to the first, and intended to be to have a second axis 62 substantially similar to the axis 62 previously described. Thus, in this case, the adjustment of the distance between the base 11 and the connecting piece 50 is necessarily a translation in the direction in which the two lights extend, unlike the previous embodiment (only one embodiment). 12) in which a rotation of the connecting piece 50 relative to the base 11 about the axis 62 is also possible. It should be noted that the support piece 10 may be formed, especially in the particular case where the surface to be dressed is a terrace, as illustrated in FIGS. 5 and 6, by a stud incorporating adjustment means known to those skilled in the art. , to cooperate with the connecting piece 50 shown in Figure 7. The fastening system 1 may comprise sealing means, comprising a seal 70, visible in Figure 4, and on the wafer 42 of each covering panel 30 in the extension of which is located the portion 33 projecting, a housing 43, such as a groove, for receiving the seal 70. Thus, the seal 70 can fill the space between two adjacent trim panels 30 assembled on the same connecting piece 50.

The invention also relates to a building comprising a fastening system 1 having the aforementioned characteristics. In the following description, the same references will be used for identical elements or providing the same function as those described above, for the sake of simplification of the description.
