Definitions

  • the present invention relates to a device for thermal break for metal profiles, especially in aluminum, which form the frame of a glass panel or similar, this device ensuring a limitation of the transmission of heat or cold by conduction to the crossing of these profiles, in particular between the exterior and the interior of a facade like the curtain wall of a building or similar construction.
  • the positioning of the bars on the two parts of the profile to join them together is not easy, especially if the frame receiving each glass panel or not is equipped with a glazing bead, i.e. an element device which extends the frame towards the external surface of the panel and has a return parallel to it for hold it by its side edges applied against the bottom of the socket of the frame which receives it.
  • a glazing bead i.e. an element device which extends the frame towards the external surface of the panel and has a return parallel to it for hold it by its side edges applied against the bottom of the socket of the frame which receives it.
  • the present invention relates to a device which allows to obtain a thermal break under conditions more effective with simpler and less expensive than in conventional solutions known in the art technical.
  • the device considered adapted to be mounted in a tubular metal profile forming the frame of reception of a filling panel housed in a cell reception provided in a support frame of a vertical curtain wall facade, characterized in that it includes a structural element forming a shield thermal, integrated into the profile and made of a material insulating, this structural element that envelops the frame being arranged on the periphery of the panel at the right and in look at the peripheral outer edge of it, the filling panel resting directly on this element.
  • the panel filling is glued against the metal profile.
  • the filling panel is applied against the metal profile by means of a glazing bead, presenting a flat return fitted with a seal sealing, extending parallel to the panel and support against the external surface thereof.
  • the element of structure forming heat shield is crimped on the metal frame profile.
  • this element is fixed like a clip on this profile.
  • the filler panel door on the frame profile at right of the structural element forming a heat shield by means of at least one support wedge, arranged under the lower edge of the panel.
  • the element of heat shield structure has at least one lip seal extending outward from frame, parallel to the plane of the filler panel, this seal being adapted to cooperate with the similar lip of a homologous seal carried by the frame of a panel filling placed in an adjacent cell of the frame.
  • the element of heat shield structure has worms inside the profile another sealing lip, forming stop barrier for depositing a silicone sealant or other, injected between the shield and the peripheral edge filling panel.
  • the reference 1 designates the shell of a building or the like, very schematically illustrated, against which is applied to the outside of this building a support frame 2 for the front of the latter.
  • This frame 2 has vertical uprights 3 and horizontal crosspieces 4, which delimit between them adjacent cells 5 in the vertical plane of the facade, these cells being intended to receive panels of filling 6, glazed or not, which thus fill the facade by realizing what is commonly called in the technical curtain wall.
  • Each filling panel 6 is preferably surrounded by a metal frame 7, intended to be housed against the bottom of each cell in the frame, the panels thus mounted in the adjacent cells of the latter, being practically only visible from outside the facade.
  • each filling panel is constituted by means of metal profiles which surround this panel according to its four consecutive sides, this frame or chassis of panel support usually being formed of four elements which are distributed along these sides by being joined from one to the other in the corners of the panel.
  • the subject of the invention is a device which makes it possible to create a thermal break in these profiles.
  • reference 8 represents a horizontal cross member of the support frame, delimiting on either side of a central element 9 with uprights vertical (not shown), two adjacent cells 5 in this frame.
  • Each of these cells is designed to receive a panel filling 7, constituted in this example by means of two glass walls 10 and 11, parallel to each other and separated according to their periphery by an intermediate element 12.
  • the panel 7 is mounted inside a frame 13 constituted by means of a tubular metal profile 14, comprising a vertical face 15 parallel to the plane of the glass walls and a horizontal face 16, perpendicular to the previous one and which extends along the lateral edge panel device 7.
  • the vertical face 15 forms the bottom of a housing 17 in which is mounted and immobilized a fixing bar 18, having an external surface parallel to the plane of the panel, the latter being glued against the bar by a layer 19 of a suitable bonding material, according to the classic technique called "VEC" for "Glazing Glued Exterior ”.
  • the panel 7 is supported by its lower edge in the figure against the horizontal face 16 of the profile 14 of the frame 13 by via a flat block 20, if applicable held between the edge of the panel and a support plate 21.
  • this face 16 of the profile 14 is arranged to include, extending beneath but against the filling panel 7, a structural element 22 constituting a heat shield, preferably made made of an insulating plastic material.
  • this shield thermal 22 is directly integrated into profile 14 of the frame 13 and is arranged so as to tightly envelop the outer periphery of the filling panel 7. It thus allows to resume, via the wedge 20 and the support plate 21, the weight of this panel.
  • the heat shield 22 is advantageously provided with minus a groove 23 for immobilization therein of heel 24 of a seal comprising a lip 25, extending outward, substantially in the plane of the panel 7, this lip being designed to cooperate with a homologous lip 26 carried by the heat shield 22a, identical to shield 22 and associated with frame 13a which supports the filling panel 7a of the neighboring cell in the framework, the mutual cooperation of the lips 25 and 26 isolating from the outside the region 27 which separates the two frames 13 and 13a of these panels 7 and 7a.
  • each profile 14 may itself have a groove 28, similar to the groove 23, in which is mounted another seal 29 to lip 30, which, with the same seal 31 on the other profile 14a, makes it possible to perfect the sealing and the insulation of the region 27.
  • a block of putty or the like 32 is advantageously injected between the filling panel 7 and the end 33 of the shield 22 opposite the metal profile 14, so as to particular to avoid water or other entry under the sign towards the interior of the building, on the other side of the facade.
  • FIG 3 illustrates an alternative embodiment in which we find the filling panels 7 and 7a with their frames 13 and 13a formed from metal profiles tubular 14 and 14a.
  • each profile has one side horizontal 16 in which is mounted an element of structure 22 forming a heat shield, this comprising a seal 24 with a lip 25 for isolate region 27.
  • each panel 7 is immobilized with respect to of its frame 13, by placing in the housing 17, not plus a bonding bar, but a seal 34, provided with several lips such as 35 which bear against the glass wall 10 in the bottom of the cell 5 which receives the panel, which is held in place by means of a glazing bead 36, immobilized like a clip or other vis-à-vis the shield 22, this glazing bead having a back plane 37 parallel to panel 7, provided at its end another seal 38, the panel thus being clamped between the seals 34 and 37.
  • the shield 22 is directly produced so as to include, coming from manufacture of the lips on its opposite lateral faces, one playing the role of the lip 25 described in the previous variants, the other marked 39, forming a barrier seal for the putty block 32 provided between the heat shield and the lower peripheral edge of the panel 7.
  • the heat shield 22 is crimped with respect to the underside 16 of the profile 14 who supports it.
  • this shield can be immobilized differently and in in particular by a clip or the like (not shown).
  • a thermal break device is thus produced simple design, integration of the shield into the profile itself so that it surrounds the panel of filling proving to be very effective, avoiding the difficulties of implementing the conventional solution to insulating strips in a metal profile in two parts.
