  • Vertical support structures are usually only connected to the load-bearing wall shell or substructure at a few points.
  • the horizontal brackets are often made of Z-shaped sheets. Adhesions of this type are also arranged on flat roofs or parapets to fasten metallic roof seals.

  • the voids between the inner wall shell and the outer cladding are completely or partially filled with insulation.
  • the distances between the console-like holding structures and the heights of the cassettes vary between approx. 450 - 1000 mm.
  • the numerous metallic connections between the outer cladding and the inner wall shell create a large number of massive thermal bridges, which significantly reduce the insulation effect and thus lead to high transmission heat losses from the walls and, of course, the corresponding roof structures. Additional heat losses also occur if the insulation materials are not pressed into the cassettes in a joint-tight manner so that outside air flows against the inner wall shell.
  • these constructions have further disadvantages.
  • the thermal bridges regularly cause condensation to form in the wall structures, which in turn impair the insulation effect and can cause corrosion damage. In the event of a fire, the thermal bridges promote energy transmission through to fire propagation.

Abstract

L'invention concerne un élément de construction destiné à être utilisé pour construire une paroi de bâtiment. Cet élément de construction comprend au moins un élément profilé en métal ou en matière plastique, ainsi qu'une isolation thermique et/ou acoustique disposée dans cet élément profilé. Cette isolation se compose d'éléments isolants présentant deux grandes surfaces parallèles espacées reliées par des surfaces latérales s'étendant sensiblement perpendiculairement les unes par rapport aux autres et par rapport aux grandes surfaces. L'objectif de l'invention est d'améliorer cet élément de construction de sorte que la stabilité dimensionnelle et par là même l'efficacité de l'isolant permettent d'obtenir un élément de construction amélioré présentant peu de ponts thermiques, les éléments individuels de l'élément de construction pouvant néanmoins être produits à moindre coût. A cet effet, l'isolation thermique et/ou acoustique (4) disposée dans chaque élément profilé (3) comprend au moins deux éléments isolants (8, 12) reliés l'un à l'autre, un premier élément isolant (8) étant calé dans l'élément profilé (3), de préférence de telle sorte qu'il remplisse sensiblement complètement ledit élément profilé, et un deuxième élément isolant (12) étant placé sur l'une des grandes surfaces (13) du premier élément isolant (8).
