Definitions

  • the invention relates to the field of cover panels composed of a core of insulating material sandwiched between two facings.
  • connection between juxtaposed panels is ensured, according to a technique well known in carpentry, by engagement of a metal profile forming a tongue having in cross section a generally rectangular shape, in grooves forming mortises and emerging from the edges of the webs of the panels.
  • the interval between the facing edges of two juxtaposed panels is, in general, sealed by means of a bead of synthetic material placed on the external part of the panels.
  • French patent application FR-A-2 678 302 uses a longitudinal joint cover carrying seals which are applied to the external face of the panels by fixing screws, passing through this joint cover and being screwed between wings projecting from the connecting tongue of the panels. This device provides a satisfactory solution to the seal of the connection but increases the installation time since it is necessary to drill the joint cover to make the holes for the passage of the screws, holes positioned differently at each installation, then put in place and screw. these screws.
  • the object of the present invention is to remedy these drawbacks by providing a connection device ensuring the desired tightness, while being easy and quick to use and by eliminating any degradation during the dismantling of the panels.
  • the connecting tongue of the panels is constituted by an extruded tubular profile comprising, between two lateral boxes connected by a web of material, a central groove with parallel lateral faces opening outwards to the outside. across the gap between two panels, while the joint cover is integral with a longitudinal central blade projecting perpendicular to the internal blade and comprising, at its free end, at least one bead capable of snap-fastening with at least two facing rib projecting from the facing faces of the central groove of the tongue.
  • the fixing of the joint cover is ensured, after engagement of its central blade between the gap and the panel, by snap-fastening of its bead with the ribs formed in the groove of the profile forming the tab for assembling the panels. Thanks to the presence of the bead along the entire length of the blade and the presence of the ribs on the entire length of the profile forming the assembly tab, there is no constraint for the positioning of the joint cover which can therefore be put in place quickly.
  • one of the sections respectively forming the tongue and the central fixing blade is made of synthetic material, while the other element is made of metal.
  • This arrangement provides the elasticity necessary for the snap connection and makes it possible to eliminate any thermal bridge formation.
  • the two ribs of the tongue on which the bead of the central strip of the joint cover is snapped in are formed by the free edges opposite two fins each projecting from the one of the faces opposite the central groove, these free edges being separated by a distance less than the transverse thickness of the bead.
  • the bead formed at the end of the central blade is formed by at least two longitudinal ribs projecting from the opposite faces of the blade and capable of cooperating each with one of the superimposed ribs projecting from the face corresponding to the groove of the tongue profile.
  • This connection mode makes it possible to adjust the compression of the seals interposed between the joint cover and the external faces of the sandwich panels.
  • the reference numerals 2 and 3 denote, in general, two covering panels each made up of a core 4 of synthetic material, for example of polyurethane or polystyrene, sandwiched between two facings, respectively , exterior 5 and interior 6, metallic or synthetic.
  • the figures clearly show that the ends of the facings 5 and 6 are folded back in 5a and 6a against the edges of the cores and that, when they are assembled, they are separated by an interval I.
  • the adjoining panels are assembled l to each other by means of a profile 7 engaging in the manner of a tongue in mortises 8 opening songs of the souls of these panels.
  • the sealed connection device comprises an external joint cover 9 provided, projecting from its face facing the external facing 5 and close to its edges, with longitudinal grooves 10.
  • these grooves have a general shape in "C” and are used for fixing the heels 12a of seals 12 made of synthetic material and working in elastic compression.
  • the joint cover 9 is made of metal, and in particular aluminum, and is integral with a central blade 13 extending over its entire length, projecting from its internal face, and comprising, at its free end, a bead 14.
  • this bead has, in cross section, a diamond shape whose width L is greater than the thickness of the central strip 13.
  • the profile 7 constituting the connecting tongue is produced by extrusion and is made of synthetic material. It comprises two lateral boxes 7a which, connected to each other by a veil of material 7b, delimit between them a central groove 15 of width greater than the interval I between panels. This groove opens on one side of the profile 7 and has straight and parallel side faces. During the assembly of the panels, this outlet is arranged so as to coincide with the interval between panels opening to the outside.
  • the two boxes 7a improve the rigidity of the profile in its parts cooperating with the mortises 8 of the panels and form longitudinal cavities the ends of which can be used, on the one hand with junction sleeves, for the assembly of sections of the profile arranged end to end, and on the other hand and with gripping means, to make the profile slide in the mortises.
  • the end-to-end joining of sections of the profile of the tongue makes it possible to recover the fragments of profiles of lengths shorter than that of the panels and to eliminate losses, without causing any damage to the device.
  • the outer edges of the groove 15 are integral with two opposite fins 16 which, in this embodiment, are each oriented transversely in the direction of the bottom of this groove, so as to form, by their free edges 16a constituting attachment ribs , a “V” for retaining the bead 14. As shown in FIG. 1, these free edges 16a are separated by a distance d which is less than the width L of the bead 14.
  • the bead 14 comes to rest on the ends of the two fins 16, which requires the operator to exert a greater effort, on the one hand, to elastically deform the two fins 16 until to clear a passage sufficient for the bead 14, and on the other hand, to compress the seals 12.
  • the sealed connection device according to the invention eliminates any formation of thermal bridges between the outside and the inside of the panels and therefore improves the 'insulation.
  • the central strip 13 which, in this embodiment, is monolithic with the joint cover 9 can, as in the embodiment described in FIGS. 3 and 4, be independent of this joint cover and be connected to it by a tenon-mortise type connection identical to that of the embodiment of Figures 3 and 4 or reverse.
  • the central strip 20 which, in this case, is made of insulating synthetic material, is provided at its end cooperating with the joint cover 22, with a transverse bar 23 giving it, in cross section, the general shape of a " T ".
  • This bar is slidably engaged in a rib 24 of section in "C”, integral with the joint cover 22 and arranged projecting from the central part of the internal face of this joint cover.
  • this joint cover is provided with lateral grooves 10 for fixing the heels 12a of seals 12 made of elastic synthetic material.
  • the connecting bead, formed at the free end of the central blade 20, is composed of at least one, and in this case by several superimposed ribs 25, formed longitudinally and projecting from the two opposite faces of this blade. These ribs are intended to cooperate with complementary ribs 26 projecting longitudinally from the faces opposite the groove 15a between the two boxes 7a of the profile 7.
  • the groove 15a has a narrower width than the interval I between panels, adapted to the thickness of the bead of the blade 20.
  • the joint cover 22 and the profile 7 are made of metal, for example aluminum, and only the central blade 20 is made of synthetic material to avoid the formation of thermal bridges.
  • the sealed connection device according to the invention provides excellent sealing, is easy to implement, is compact and eliminates any thermal bridge. In addition, when dismantling the panels, it leaves no visible trace on them and can be reused.
