  • the prefabricated wooden frame panel comprises a frame made up of uprights and crosspieces, and in which there is insulation of mineral origin such as rock or glass wool.
  • the prefabricated wooden frame panel is covered, on one side, with a light concrete skin.
  • This document uses a process comprising a step of pouring lightweight concrete into the mold, the frame of the prefabricated panel previously equipped with a wood/concrete connector is then positioned on the lightweight concrete slab before setting. After the concrete has set, the prefabricated panel equipped with the lightweight concrete skin is raised.
  • a vapor barrier is placed between the prefabricated wooden frame panel and the layer of lightweight concrete.
  • the latter is covered with an interior finishing coating which is poured after the light concrete skin.
  • the prefabricated panel is also covered, on a second side, with an exterior cladding type covering.
  • a synthetic exterior insulation is placed between the exterior covering and the frame of the wooden frame.
  • This prefabricated wooden frame panel has the particular disadvantage of including an interior finishing covering.
  • the interior cladding panel gives the prefabricated wooden frame panel a clean and neat interior finish, but requires an additional casting step during manufacturing.
  • prefabricated panels are assembled, notably to each other, but also to a floor which can be of various types, concrete, wood, metal, etc.
  • a panel/floor keying system making it possible to take up the loads which apply to a prefabricated wooden frame panel along three axes of a three-dimensional reference X, Y, Z.

  • the cooperation between the first module and the second module of the keying part makes it possible to anchor a wooden construction panel to a floor according to a mechanical connection taking up the loads which apply to the prefabricated panel along three axes X, Y, Z of a three-dimensional reference.
  • This mechanical connection is made through the base of the second module which is secured to the floor.
  • the two modules are independent to reduce installation constraints. However, the two modules are configured to be assembled together during installation.

  • the step of assembling, on the one hand, the first module secured to the timber panel, and on the other hand, the second module secured to the floor also links a lower rail to the timber panel, the wooden construction panel resting on the bottom rail.
  • This step is carried out by fixing the base on a first face of the lower rail, the wing of the second module being positioned against a second adjacent face of the first face of the lower rail.

  • the anchoring process includes a step of supplying a wooden construction panel.
  • the method may include a step of providing a lower rail 7.
  • the anchoring method also includes a step of providing a keying part 6 defined according to the invention.
  • the anchoring method also comprises a step of securing the first module 63 of the keying part 6 to one face of the timber panel. This step is carried out using the holes 650 provided on the second portion 65 of the first module 63. In the case of a prefabricated panel 1 with a wooden frame, the first module 63 is secured to at least one upright of the prefabricated panel 1 .
  • the anchoring method includes a step of securing the second module 60 of the keying part 6 to the floor. This step is carried out through at least one anchoring screw 67 which cooperates with at least one drilling 610 made in the base 61 of the second module 60.
  • the anchoring method comprises an assembly step, on the one hand, of the first module 63 secured to the timber panel, and on the other hand, of the second module 60 secured to the floor, is carried out through the wing 62.
  • the wooden construction panel is secured to the floor through the second module 60.
  • This step is carried out by at least partial covering of the first portion 64 of the first module 63 with the wing 62.
  • the first portion 64 and the wing 62 are secured via at least one self-perforating mechanical element 660 which cooperate with the lower holes 640 of the first portion 64 which passes through the wing 62.
  • the self-perforating mechanical element 660 is inserted in the lower part of the timber panel.
  • the method can also include a step of connecting the base 61 of the second module 60 to the construction wood panel. This step is carried out using fixing elements 66 which cooperate with holes 610 provided on the base 61 of the second module 60.
  • the step of assembling, on the one hand, the first module 60 secured to the wooden construction panel, and on the other hand, the second module 60 secured to the floor, also connects a lower rail 7 to the timber panel.
