Definitions

  • the present invention relates generally to the lining of walls for insulation or aesthetic purposes. It relates more particularly to a spacer accessory placed transversely between the wall to be lined and a lining partition to keep the latter at a distance from the wall to be lined.
  • a lining partition (counter-partition or false ceiling) is attached to a lining framework which is itself fixed to structural elements of the wall to be doubled, at a given distance from the latter.
  • a thermal and / or acoustic insulation lining (often called an insulation complex) is inserted between the wall to be lined and the lining partition.
  • the insulation lining typically includes, on the one hand, one or more layers of fibrous insulating material such as mineral wool and, on the other hand, at least one wind barrier or vapor barrier. This membrane is most often interposed between the layer of fibrous material and the lining partition, typically attached to the partition, optionally interposed between two layers of fibrous material.
  • Each spacer accessory comprises a main body in the form of a rod extending transversely to the wall to be lined and to the lining partition, one end of which is provided with means for its cantilever attachment to a structural element. of the wall to be doubled and the other end of which is provided with means for its assembly with the doubling framework.

  • these assembly means 19 comprise two notches or grooves 19a, parallel, arranged on the front face of the connecting piece 20. These notches 19a are adapted to cooperate by clipping with a slat 6, 7.
  • Each slat 6, 7 is here produced in the form of a metal profile, or fur, with a C-shaped section having re-entrant edges, pointing towards each other to engage like a clip with the notches.
  • the assembly means 19 comprise a single notch or circular groove. This circular notch makes it possible to modify the angular position of the slat as required.
  • the assembly means 19 comprise at least one tab 19b, preferably two parallel tabs 19b. These legs extend in a direction parallel to the side wall of the second jaw. These tabs 19b are arranged to have a shape and dimensions allowing said tabs to insert it into the space between the edges of the C-section profile. Preferably, the edges are re-entrant, pointing towards one another. In this case, the tabs 19b are arranged to have a free end or leading edge facilitating the insertion into the space between the edges of the section C-section. For this, the free end has a shape having a tapering end such as a rounded / circular shape or bevel shape.
  • This thinned shape advantageously makes it possible to press on the edges and to separate them in order to facilitate the insertion of the tab.
  • the second jaw 17 acts as a connecting piece 20.
  • the lower face 172a of the second jaw 17 is the face on which the assembly means 19 are arranged as visible at the bottom. figure 17 .
  • the means 16 for coupling the second jaw to the first jaw are designed so that the amplitude of the rotation to be applied to the second jaw for its assembly with the first jaw is limited.
  • This limitation is such that this amplitude of the rotation is at most 90 °.
  • this amplitude is at most 45 °.
  • This limitation of the rotation of the second jaw 17 relative to the first jaw 15 for their assembly makes it possible to limit the stresses applied to the membrane M and thus to limit the wrinkling of this membrane. Such wrinkling is representative of an alteration.
  • the limitation of the rotation of the second jaw relative to the first jaw for their assembly thus makes it possible to limit this deterioration and therefore to reduce the risks of perforations of the membrane.
  • the panels of insulating materials are at least partially supported by the bracing devices according to the invention. More particularly, the first jaw 15 and its lower face 152a interact with the insulating panel or panels. Indeed, in the case of a wall or a roof, the insulating panel is placed so as to rest on the lower face 152a of the first jaw. This is all the more true in the case of a roof where the insulating panels are retained only by the lower face 152a of the first jaw of each bracing device.
  • said lower face 152a of the first jaw optionally comprises teeth or spikes extending orthogonally to said lower surface. These teeth or pins are used to fit into the insulation panel to improve its retention.
  • the central portion 11 can thus be in the form of a plate or of a tube or of a section.
