Definitions

  • the present invention relates to composite beams glued, glued wood, cross section in 1 intended in particular for concrete formwork on construction sites: Residential buildings, public or industrial, structures or civil engineering.
  • the beams of this kind already known have a symmetrical cross section with respect to a horizontal axis, the two members being identical, massive and rectangular. They often replace squared timber (bastaings or planks) thanks to their significant weight gain with equal resistance and their longevity.
  • the various elements are assembled by nailing and gluing.
  • the slenderness of the section (ratio of height to width) varies from 2.5 for the lightest beams to 3.6 for the tallest.
  • the beams according to the invention make it possible to avoid these drawbacks.
  • the general cross-section of 1 has two members 1 and 2 of different sections (fig. 4): An upper member 1 of rectangular section or close to the rectangle, a lower member or shoe 2, wider and of average thickness more low.
  • the two members 1 and 2 have equivalent inertia with respect to an axis located halfway up the section.
  • Each frame can be massive, composed by gluing or laminated-glued.
  • the profile of the beams is reminiscent of that of a conventional skid rail.
  • the shuttering skin is nailed to the shoe 2 which, due to its width B, significantly reduces the free span of the shuttering panels, which makes it possible to further space the beams arranged in vertical stiffeners.
  • the core 3 of the beams according to the invention consists of one or two plywood boards according to the possible arrangements indicated (fig. 4a and 4b).
  • a feature according to claim 2 is to arrange the plywood son ply at 45 ° relative to the members 1 and 2, which, at equal thickness, significantly increases the shear strength.
