Definitions

  • the present invention relates to the construction of finishing works in seismic zones, and more particularly of partitions or inner partitions.
  • the load-bearing structure rests on the foundations.
  • the non-bearing structure is fixed to the bearing structure by means of a frame called the primary frame.
  • the non-supporting structures can themselves comprise, when necessary, a frame called the secondary frame, fixed to the primary frame.
  • the non-bearing structure includes the assembly of various elements of the work and in particular the assembly of plasterboard between them in order to define volumes inside the building. This assembly of panels requires the panels to be fixed to the secondary and primary framework.
  • the problem that the invention proposes to solve is to provide a seismic partition or counter-partition resistant to seismic stresses.
  • the inventors have demonstrated that it is possible to separate the partition from the load-bearing structure, by installing slides on the vertical and horizontal sides of the partition. This allows the load-bearing structure to move without transmitting movements and stresses to the partition, and without shearing the fasteners that hold the partition.
  • the present invention relates to a paraseismic partition having the characteristics presented in claim 1.
  • the invention offers at least one of the decisive advantages described below.
  • the seismic partition according to the invention can withstand an earthquake without deteriorating and without separating from the structure.
  • the seismic partition according to the invention does not collapse during an earthquake avoiding injury to the occupants of the structure.
  • the seismic partition according to the invention makes it possible to keep the evacuation routes of the structure available and free, without obstructing them.
  • the seismic partition according to the invention can remain intact during earthquakes of low or medium intensity, which makes it possible to accelerate the restoration of the building and to reuse the buildings in a short time.
  • the seismic partition according to the invention can be produced at lower cost, using commercial rails and uprights.
  • bearing structure is preferably meant according to the invention all the elements of a structure carrying more than their own weight.
  • elements which can be load-bearing mention may be made of posts, partitions, floors, walls.
  • primary framework is preferably meant according to the invention all the rails and crosspieces made of wood or metal or synthetic materials which are fixed to the supporting structure of the construction or to the foundation and which serves as a support for elements of the work such as filling elements.
  • secondary frame is preferably meant according to the invention all the uprights and crosspieces made of wood or metal or synthetic materials, held in place by the primary frame and which serves as a support for panels, electrical equipment, frames, frames, infills or cladding.
  • partition is meant both partitions and inner partitions.
  • the primary or secondary framework of the seismic partition according to the invention can be metallic or wooden, or other materials.
  • the framework is made of metal.
  • the seismic partition according to the invention comprises a primary metal framework comprising an upper rail fixed to the ceiling and a lower rail fixed in the floor. These two rails are arranged in the same vertical plane.

  • the rails of the seismic partition according to the invention have a substantially U-shaped section. They may be commercially available rails.
  • the flanges of the rails have a flange height of at least 25 mm, preferably at least 40 mm.
  • the metal thickness of the rails is greater than normal, preferably greater than or equal to 0.5 mm, more preferably equal to 1 mm.
  • the uprights of the secondary framework have a section smaller than the section of the rails of the primary framework. These amounts can be regularly spaced, and generally of 40 or 60 cm.
  • the uprights of the secondary framework can be single or double, for example back to back or nested.
  • the uprights of the secondary framework can be substantially parallel. They can be arranged in the same vertical plane.
  • the uprights of the secondary framework are partially or totally housed in the rails of the primary framework.
  • the uprights of the secondary framework are partially or totally housed in the rails of the primary framework.
  • the primary framework completely or partially covers the flanges of the uprights of the secondary framework.
  • the secondary framing uprights can move relative to the primary framing rails in a vertical and horizontal direction. They can slide. Preferably the amounts are of length less than the height of the partition, from 5 to 10 mm.
  • the panels of the seismic partition according to the invention are fixed to the uprights of the secondary framework.
  • the length of the panel in the vertical direction should be 5 to 10 mm less than the total height of the partition.
  • the width of the panel in the horizontal direction should be less than 5 to 10 mm compared to the total width of the partition.
  • the panels of the seismic partition according to the invention are not fixed to the primary framework. These panels are independent of the primary framework and thereby of the supporting structure, that is to say is separated.

  • the plate based on hydraulic binder which is suitable for the element according to the invention is a plasterboard having a core of gypsum, the density of which can change as a function of the distance from the surface, with for example a low density core layer incorporating foaming agents into the dough, this core layer being sandwiched by high density surface layers (dense layer).
  • a plasterboard having a core of gypsum, the density of which can change as a function of the distance from the surface, with for example a low density core layer incorporating foaming agents into the dough, this core layer being sandwiched by high density surface layers (dense layer).
  • An example of this type of board is the conventional plasterboard type BA13 with dense layers.
