Definitions

  • the present invention relates to construction assemblies intended for the external faces of buildings.
  • the present invention relates to the field of fixing double skin cladding to the structure of such a building.
  • real estate buildings can be thermally and/or acoustically insulated using appropriate construction elements, such as double-skin cladding.
  • double skin claddings conventionally comprise at least one interior skin consisting of at least one interior plate, fixed to the building concerned, and at least one exterior skin attached and fixed to this interior skin.
  • a thermally and/or acoustically insulating panel is interposed between the interior plate of the interior skin and the exterior skin in order to ensure the thermal and/or acoustic insulation of the building.
  • the inner skin of a double-skin cladding also comprises a plurality of fixing wings which extend transversely to the inner plate and on which fixing lugs are fixed which make it possible to connect the outer skin to the inner skin. More particularly, these fixing tabs are fixed on the upper faces of the fixing wings, that is to say the faces of these fixing wings turned towards the sky when the double skin cladding is mounted on the building concerned. These fixing wings are different depending on the supplier. Furthermore, the upper faces of these fixing wings may have ribs of different sizes, shapes and positions. These structural differences require the manufacture of as many different fixing lugs as there are fixing wings, which increases the production costs of these fixing lugs and complicates the assembly operations.
  • the document EP2354368A2 discloses this type of mounting bracket.
  • the present invention aims to resolve at least this drawback by proposing a fixing bracket adaptable to the majority of fixing wings currently existing on the market, thus making it possible in particular to achieve economies of scale.
  • An object of the present invention thus relates to a fixing bracket configured to connect an inner skin to an outer skin of a construction assembly intended for a building, the fixing bracket comprising at least one main wall, at least one fixing wall and at least one attachment wall, the attachment wall and the attachment wall being integral with the main wall, the attachment wall being configured to be made integral with the interior skin, the attachment wall being configured to be made integral with the outer skin, the main wall extending mainly in a first plane, the attachment wall extending mainly in a second plane, the fixing wall extending mainly in a third plane, the second plane being secant of the first plane and the third plane.
  • the main wall, the fixing wall and the attachment wall extend in three planes distinct from each other.
  • the orientation of the main wall relative to the hanging wall limits the risks of accidental folding of this main wall once the fixing tab connects the inner skin to the outer skin.
  • the fact that the main wall extends in a plane intersecting the attachment wall gives the fixing bracket better mechanical strength, which consequently improves the mechanical strength of the outer skin on the skin.
  • the fixing bracket comprises at least one force absorption wall secured, at least, to the main wall, this force absorption wall extending mainly in a fourth plane intersecting the first plane in which is mainly the main wall and the second plane in which the hanging wall is mainly located.

  • the third plane and the fourth plane are parallel between them, while the second plane is, as previously mentioned, secant, in this case perpendicular, to these third and fourth planes.
  • the attachment wall is perpendicular to the main wall, to the fixing wall and to the force recovery wall, the fixing wall and the force recovery wall being parallel to each other.
  • the main wall, the fixing wall and the hanging wall can form a one-piece assembly.
  • the main wall, the fixing wall and the hanging wall form a single assembly which cannot be separated without causing deterioration of the main wall, the fixing wall or the hanging wall.
  • the main wall, the fixing wall, the attachment wall and the force recovery wall form a one-piece assembly as defined above.
  • at least one of these walls, for example the attachment wall can be machined separately from the three other walls, then made integral with the latter for example by welding or by gluing. It is understood that any other known means making it possible to secure the machined wall independently of the others can be used without departing from the context of the present invention.
  • the force recovery wall can be interposed, at least partially, between the attachment wall and the main wall.

  • This force recovery wall makes it possible to better distribute the forces undergone by the fixing lug according to the invention so that the latter can have reduced proportions compared to the fixing lugs currently used, while ensuring a optimal mechanical support of the outer skin on the inner skin.
  • the fixing surface can be provided on a part of the force absorption wall which extends beyond the attachment wall. Such a configuration makes it possible to make this fixing surface accessible, that is to say that the attachment wall does not obstruct this fixing surface, which facilitates the possible fixing of the force recovery wall to the inner skin.
