  Method of manufacturing a construction element and element obtained by this process
 It is known that the plates manufactured by agglomeration of particles or fibers are more or less resistant and brittle and that they cannot be obtained in great thickness and dimensions, the pressure necessary for the correct agglomeration cannot be obtained economically.



   It is also known that these plates have considerable advantages over the wood or the materials they replace, because they are obtained from waste wood, plants or minerals and therefore at a particularly advantageous price. In addition, natural or artificial fibers can be used for their manufacture. All the plates thus obtained are in particular dimensionally stable, do not exhibit the defect of deformations, are moreover insensitive to chapping and hardly combustible.



   The object of the invention is to obtain, while retaining the qualities of these plates, construction elements based on fibers or agglomerated particles of great thickness and dimensions and of excellent mechanical strength.



   The method of manufacturing a construction element such as for example a panel, beam, crosspiece, plank, object of the invention, is characterized by the fact that several thicknesses of plates formed by a base material are assembled by gluing. particles or agglomerated fibers.



   A further subject of the invention is an element obtained by this method and which is characterized in that it has on at least one part an assembly of several thicknesses of glued plates, these plates being made of a material based on particles. or agglomerated fibers.



   The appended drawing represents, by way of example, two embodiments of a construction element according to the invention in which:
 Fig. 1 shows a partial section of a first embodiment of this element, and
 fig. 2, a partial section of a second embodiment.



   The element shown in fig. 1 comprises three plates 1, 2, 3 made of a material based on particles or fibers agglomerated by a binder. These three plates are glued together with a high shear glue based on polyurethane or epoxy for example. The number of glued plates is given as an example, it could be greater or less than three.



   Depending on the width of these plates, the element thus assembled may constitute either a panel, or a beam, or a cross member, or a plank.



   The particles or fibers used may be vegetable or mineral and their binder organic or inorganic.



   However, preferably, the fibers or particles are made of wood and their binder is a synthetic resin.



   In the second embodiment shown in FIG. 2, the element comprises two plates 1 and 2 bonded to strips 3 of the same material based on particles or agglomerated fibers. These bands can be parallel to each other or form braces or a frame.



   This lighter embodiment is ideally suited to serve as a base for making an element forming a panel to form walls, for example.



   As of course, the elements thus formed can be coated with a finishing coating: wood, plaster, paper, sheet of plastic, ceramic or stone, etc., in order to give them the desired final appearance.

 

   The elements obtained by this process have mechanical characteristics at least equal to or superior to those of the base materials.



   The elements can be designed so as to leave voids or to protrude a plate so as to obtain tenons, mortises or interlocking, without machining, all possible shapes and uses can be imagined.



   Partitions or panels, the central core of which is made from a material of the same type, have little deformation and are particularly rigid.



   By the very nature of the material used, excellent thermal and sound insulation is achieved by the elements obtained by the process.
