Definitions
- the present invention relates to beams made of glued wood intended in particular for concrete formwork on construction sites: Residential, public or industrial buildings, structures or civil engineering. Beams of this kind already known often replace squared timber (baslaings or planks) thanks to their significant weight gain with equal resistance and to their longevity.
- the various existing beams can be reduced to two types (fig. 3) - A trellis where the members are joined by struts.
- the various elements are assembled by nailing and gluing.
- the cross section of the beam is symmetrical with respect to a horizontal axis, the two members are identical, massive and rectangular.
- 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 main disadvantages of this type of section are:
- the cross section has two members of different sections (fig. 4): An upper member of rectangular section or close to the rectangle (I) A lower member or skid, wider and of medium thickness more fault (2).
- the two members have equivalent inertia with respect to an axis located halfway up the section.
- Each frame can be massive, composed by gluing or glued laminated.
- the profile of the beams is reminiscent of that of a classic rail with pad.
- the beam resting on its. skate is perfectly stable to the passage of workers who walk on narrow upper members.
- the shuttering skin is nailed to the shoe which, because of its width, significantly reduces the free range of the shuttering panels, which allows more space between the beams arranged in vertical stiffeners.
- the core of the beams (3) according to the invention consists of one or two plywood boards according to the possible arrangements indicated (fig 4).
- the peculiarity consists in placing the wires of the plywoods of the plywood at 45 ° relative to the members, which, at equal thickness, notably increases the shear strength.
