Abstract: An assembly member includes a rod having at one end thereof a head for driving the rod in rotation, a threaded part at an opposite end and, between the threaded part and the head, a smooth part the diameter of which is markedly larger than a threadroot diameter of the threaded part. Such member is used for the fastening of insulating layers of facade coverings or claddings.

Abstract: A leaktight covering, in particular for an industrial building, includes a loadbearing element adapted to be fixed to a framework element of the building, a layer of an insulating material arranged on the loadbearing element, and a cladding covering the layer of insulating material, with connection structure holding such three components assembled together. A first member is used, on the one hand, to ensure fixing of the loadbearing element to the framework element and, on the other hand, forms part of the connection structure. A second member is linked to the first member and to the cladding. In a first embodiment, the first member is a screw screwed into the framework element, and the connection structure includes a hollow, cylindrical intermediate piece, a bottom of which is fixed to the loadbearing element via the screw.

Abstract: The insulating element is formed by a rectangular panel (1) composed of insulating material, such as extruded polystyrene foam whose edges (4, 6) include a longitudinal groove forming a rabbet (8) or a center groove (10). A pasty coating (2) containing mineral particles covers one of the sides of the panel (1) and a flat sealing element (14) is formed on two adjacent edges of the element and permits a rapid and simple assembly of the element with two other respectively juxtaposed and superimposed elements. This sealing element maintains the edges of the elements spaced apart on the outer side of the assembly but closes in a fluidtight manner the side facing the wall to be insulated.

Abstract: The structure comprises a heat insulating panel maintained between an inner metal revetment and an outer metal revetment. The revetments are provided with ribs which project into the panel and the ribs of the two revetments are perpendicular to one another. A thin core of insulating material is applied against one of the revetments by a thin and solid metal sheet.

Abstract: The wall comprises a closed acoustic box-structure which is defined by a slightly ribbed sheet and a flat sheet. The box-structure has lateral ribs which extend beyond the sheet. A panel of high-density mineral wool which is of small thickness is enclosed inside the box-structure. A heat insulator covers the box-structure and the ribs of the box-structure and is protected by an outer trough which has ribs or corrugations perpendicular to the ribs of the box-structure.
