Definitions

  • the present invention relates to the field of wood processing, in particular for its use as a frame, and relates to a beam of glued laminated wood having, in cross section, cells, or the like.
  • the quality of the surface condition of glued laminated wood beams is also linked to the presence of defects appearing during rendering, such as, for example, knots, which can have a harmful influence on the mechanical strength of the beams thus obtained, in particular when these defects are located in the external zones.
  • CH-A-175 272 Also known from CH-A-175 272 is a wooden construction element constituted by squared strips assembled together by means of tongues fixed in offset grooves provided in the strips, the external space delimited by these strips and the strips. being filled by means of wooden inserts, so that an internal cell is formed between the tongues.
  • DE-A-396 738 describes the manufacture of walls with vertical boards assembled together by covering their edges.
  • the use of such boards for the manufacture of walls is carried out for a decorative purpose, and DE-A-396 738 does not allow the obtaining of elements of square or rectangular section with flat external surfaces and entirely closed by means of said boards.
  • the present invention aims to overcome these drawbacks.
  • a glued laminated wooden beam of the type described in DE-A-396 738 that is to say which is constituted by a superposition of wooden strips, of two different types delimiting between they alveoli, or the like, which have a random section, the two edges of the first type of lamella being squared while only one edge of the second type of lamella is squared, the other edge being provided with a line.
  • the beam of the above type is characterized in that the cells result from the arrangement of two strips of the first type, with squared edges, the width of which is equal to the width of the beam, placed on one side and other of two lamellae. of the second type, with a single squared edge so that the squared edges of the two types of lamellae are aligned to form the lateral faces of the beam, and that the outlines of the lamellae of the second type are arranged in look at each other inside the beam, the use for producing strips of tapered logs or logs so that the general direction of the cells is not parallel to said lateral faces of the beam.
  • the glued laminated wood beam is characterized in that the cells 1 result from the arrangement of two strips 2 of the first type, with squared edges whose width is equal to the width of the beam, placed on either side of two lamellae 2 'of the second type, with a single squared edge so that squared edges of the two types of lamellae are aligned to form the lateral faces of the beam, and that the outlines of the lamellae 2 ′ of the second type are arranged opposite one another inside the beam, the use for the production of strips of truncated logs or logs making that the general direction of the cells 1 is not parallel to said lateral faces of the beam.
  • Figures 2 and 3 show the embodiment of the beam starting from a plate 3 ( Figure 3), which is outlined in two genera parallel trices 4 to form a square lamella A and two lamellae with edges not delineated B and C.
  • the formation of a beam according to the invention is carried out by turning along the generator 4 of the strip B and by turning 180 ° then around the other generator 4 of the lamella C, this embodiment being repeated until the desired dimensions of the beam are obtained.
  • FIG. 4 represents an alternative embodiment of the invention, in which the beam is constituted by a superposition of wooden strips 2, 2 ′ of two different types delimiting between them cells 1, or the like, having a random section, the two edges of the first type of lamella 2 being squared while only one edge of the second type of lamella 2 'is squared, the other edge being provided with a line, and is characterized in that the cells 1 result from an arrangement staggered lamellas 2 of the first type, with two squared edges, and lamellas 2 'of the second type, with a single squared edge, so that squared edges of the two types of lamellas 2, 2' are aligned to form faces lateral of the beam, and that the outlines of the lamellae 2 ′ of the second type are arranged towards the inside of the beam opposite a squared edge of the lamellae 2 of the first type so that the width of the cells 1 is variable in function of ut ilisations provided for the beam, by increasing or decreasing the overlap of two
  • the strips 2, 2 'used are advantageously obtained by selective trimming "without defect", that is to say that they have in their outer zones a continuity of the fibers, the nodes being maintained in the middle area.
  • the aesthetic and mechanical qualities of the beam are reinforced in the highly stressed areas, the usual defects of the wood being included in the mass of the elements or beams thus produced. Therefore, it is no longer necessary to remove, by purging the defects, a large part of the strips obtained by trimming.
  • the cells 2 are used for carrying out a fungicidal, insecticidal or flame-retardant treatment, or for the passage of cables, sheaths, or cables to other steel elements allowing the prestressing of the beam obtained, so that the qualities of the latter can be profoundly modified.
  • the cells 2 can also form ventilation channels by means of a moving or stationary air knife, or fluid distribution channels.
  • the cells 2 can be filled with insulating and / or flame-retardant material, or even metallic elements for structural reinforcement.
  • the invention it is possible to economically reconstruct beams of any cross section and length by using almost the entire volume of material of the original logs or logs, whatever their initial length and conicity. It is thus possible to use and develop the usual by-products of sawing, such as edging, in the organized form of the original material, for the benefit of resistance.
  • the appearance of facing can be achieved even with poor quality wood, and the good mechanical characteristics of so-called "edge" wood are fully exploited thanks to the integration of these woods.
  • the vertical inertia and the horizontal inertia are greater than that of solid beams with equal mass of material.
  • the internal tensions are higher. awarded.
  • all of the woody material can be used.
