Definitions

  • the present invention relates to the construction sector. It relates more particularly to a highly insulated prefabricated carrier element and to fixing means of any type of cover or outer facing on this prefabricated element.
  • the building designers use to realize the walls of a construction, a carrier element, connector elements attached to the carrier element to assemble the outer face and finally an insulator deposited on the carrier element and between the fasteners for the exterior cladding of the building. Everything is done in three phases on site.
  • the prefabricated elements in the workshop are more and more used in the construction with a goal of saving time and obvious quality.
  • insulated prefabricated concrete elements there is the system of insulated sandwich cladding panels. This is a classic sandwich panel type concrete-insulation-concrete. The disadvantage of these panels is that they are not connected to each other which causes movements and cracks not acceptable for a home. In addition, these panels must be fixed on a supporting structure.
  • roof or wall panels with an insulating layer and a layer of concrete contiguous.
  • the panel has two layers of cellular concrete, one of which is heat-insulating.
  • the layers are traversed by a frame support which is surmounted by a U-shaped section in which can be housed a counter-lathing in the case of a cover panel.
  • This panel has several disadvantages.
  • As a wall element it is self-supporting but not carrying, that is to say that it carries its own load and possibly the outer and / or inner coating but can not take up the loads of the floors of the construction.
  • the panel still requires the use of a wooden batten as an intermediate for fixing the coating.
  • this type of attachment via a wooden batten does not allow to fix hooks for brick or stone siding. Such a system also requires proper ventilation of the wooden batten.
  • Prefabricated elements including brick cladding are also known.
  • the main ones disadvantages of these prefabricated elements are the fragility of the product during its manufacture and its assembly, the visibility of the mounting joints outside and the lack of flexibility of the product with regard to the urbanistic prescriptions (only suitable for brick facades).
  • the present invention is more particularly to achieve a prefabricated element for external walls and roofs for fixing any type of facings and covers respectively.
  • the present invention also aims at producing a prefabricated element which is carrier and not only self-supporting.
