Definitions

  • the present invention generally relates to the lining of walls for insulation or aesthetic purposes. It relates more particularly to a bracing 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 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 packing 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 or vapor barrier membrane. 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.

These lugs 19b are arranged to have a shape and dimensions allowing said lugs to insert it into the space between the flanges of the C-section profile. Preferably, the flanges are re-entrant, pointing towards each other. In this case, the lugs 19b are arranged to have a free end or leading edge facilitating insertion into the space between the edges of the C-section profile. For this, the free end has a shape having a tapering end such as a rounded/circular shape or bevelled shape.
  • This thinned shape advantageously makes it possible to press on the edges and to spread them apart in order to facilitate the insertion of the tab. Once inserted into the rim, the lug(s) are held in place by the edges of the profile which tend to return to their initial position and therefore operate a tightening.
  • 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 figure 17 .
  • the coupling means 16 of the second jaw on 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 with respect 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 crumpling is representative of weathering.
  • the limitation of the rotation of the second jaw with respect to the first jaw for their assembly thus makes it possible to limit this alteration and therefore to reduce the risks of perforations of the membrane.
  • means may also be provided for ensuring a seal between at least one of said jaws of said spacer accessory and the stem of the latter.
  • the panels of insulating materials are at least partially supported by the spacer devices according to the invention. More particularly, the first jaw 15 and its lower face 152a interact with the insulating panel(s). 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 barbs 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 a tube or a profile.
