  • the assembly continues with the implementation of at least a second step E2 which aims to secure at least one fixing lug according to the invention on a fixing wing of the inner skin.
  • At least a third step E3 consists of the installation of the acoustic and / or thermal insulation panel.
  • the thermal and / or acoustic insulation panel may have a cutout suitable for receiving, at least, the fixing wing of the inner skin.
  • this cutout can also be adapted to receive the fixing lug.
  • this cutout could be made in the thermal and / or acoustic insulation panel when the latter is made of rock wool.
  • this panel may be devoid of any cutout.
  • a fourth step E4 is aimed at fixing the outer skin on the fixing lug, whether or not via a secondary framework, which is the subject of the invention.

  • the first sub-step SE21 consists in positioning the fixing lug so that the force-absorbing wall of this fixing lug is arranged in contact with the return lip of the fixing wing concerned.
  • the second sub-step SE22 consists in securing the fixing zone of the main wall of the fixing lug on the upper face of this fixing wing, in particular by using the second fixing means as described above.
  • the third sub-step SE23 consists in fixing the force-absorbing wall of the fixing lug on the return lip of the fixing wing of the inner skin, by the implementation of the two third fixing means as described above.
  • the second sub-step SE22 and the third sub-step SE23 are independent and provision may be made to carry out only one of the two without departing from the context of the present invention.

  • the second substep SE22 and the third substep SE23 can then be carried out in this order or in a reverse order without distinction.
  • the third step E3 consists in positioning the insulation panel in the internal space of the construction element. Where appropriate, this insulation panel must be positioned so that any cutout made in the latter is arranged opposite the fixing lug and the fixing flange.
  • the fourth step E4 consists of the implementation of the first fixing means so as to fix the outer skin or the secondary framework on the fixing wall of the fixing lug.
  • the invention therefore proposes a simple and standardized means which makes it possible to assemble an outer skin to an inner skin so as to form a construction element providing thermal and / or acoustic insulation of a building to which it is fixed. It is understood that the invention is not limited to the means described and illustrated here and that it also extends to any equivalent means and configuration and to any technically operative combination of such means.
  • the shape and arrangement of the fixing means described for fixing the fixing lug on the inner skin and on the outer skin can be modified without harming the invention insofar as they fulfill the functionalities described in the this document.
