Definitions

  • the present invention relates to a wooden beam of the type reconstituted and comprising a central structure or core and a outer covering secured to the latter and extending to less on two adjacent faces of said beam, said central structure or core being made from several pieces of laminated wood.
  • This type of so-called reconstituted beam is traditionally a assembly of wooden elements, said elements being assembled so as to obtain the shape and general appearance of a part or a solid wooden beam.
  • One of the drawbacks of reconstituted type wooden beams the prior art is that, being constructed with a multitude elements that are not dimensionally stable, these beams have a structure that tends to fall apart quickly over time.
  • the present invention is intended to remedy the aforementioned drawbacks.
  • the invention relates to a wooden beam of the type reconstituted comprising a central structure or core and a outer covering secured to the latter and extending to less on two adjacent faces of said beam, said central structure or core being made from several pieces of laminated wood.
  • said pieces of wood of this central structure or core are of several species and wood heated to high temperature.
  • beam is not limiting and can also designate rafters, joists, etc.
  • all the pieces of wood realizing respectively the central structure or soul and the exterior cladding is made of wood heated to high temperature.
  • the species of wood used for the pieces of wood making the central structure or soul are different from the essence of wood used for the pieces of wood making the dressing outside.
  • the species of wood used for the pieces of wood making up the central structure or core are common essences.
  • common species we mean wood species that are generally inexpensive to purchase (softwoods, poplars, eucalyptus ).
  • the wood species used for the pieces of wood realizing the exterior cladding is a noble essence.
  • the noble essence wood making the dressing exterior is chosen from the group (oak, walnut, ash, elm, maple) and / or in the group (mahogany, teak, ebony, sepia, sapelli, rosewood).
  • a type wooden beam reconstituted has a central structure or core (1).
  • a beam of the reconstituted type also includes a cladding exterior (2) lining the central structure or core (1).
  • the central structure or core (1) consists of an assembly of pieces of wood (4) of one or several different species previously heated to high temperature ensuring stability of said pieces of wood dimensional, said essences preferably being different from that used for exterior cladding.
  • This technique consists in assembling pieces of wood, for example planks, boards or veneers superimposing said pieces, preferably wire parallel, and joining them by gluing.
  • the structure central or core (1) has at least one metal insert (not shown) extending along the longitudinal axis of the beam.
  • a beam of the reconstituted type is thus obtained with a improved rigidity.
  • the outer covering (2) is an assembly of parts of wood (3) of noble essence.
  • the pieces of wood making the exterior cladding are assembled using the so-called technique laminating (glulam).
  • the exterior cladding (2) is secured to the central structure or core (1) of the beam by collage.
  • the dressing exterior cannot be limited to two faces of the beam, for example if the beam is fixed at the junction of a wall and ceiling.
  • beams of the reconstituted type according to the invention by their dimensional stability, can advantageously replace solid wood beams in constructions modern.
  • the present invention finds its application in decoration and construction structures in the building.
