Definitions

  • these spans can be placed either by means of an arrow or using a manipulator.
  • scissor-type structures or simple structures have generally been formed by welded metal beams of large section or by lattice structures, so that the weight spans is important which does not facilitate their installation.
  • the subject of the present invention is a transportable span for crossing breaches comprising at least one pair of parallel sections and connected together to form a raceway, each section consisting of several modules juxtaposed and joined together, made of light material of low density and high strength, characterized in that each module is formed by a succession of boxes placed end to end in the direction of the length of said section and secured to each other.
  • the span shown in FIG. 1 is made up of several pairs of sections 1, the sections of each pair being interconnected by crosspieces 2.
  • Each module 10a, 10b, 10c ... has the shape of a box of generally parallelepiped shape whose upper face is slightly inclined to form a continuous curved profile.
  • each module 10a, 10b, 10c ... is formed by a succession of boxes 14 placed end to end in the direction of the length of said section 1.
  • the walls 12a, 12b and 13a, 13b are assembled together by suitable means.
  • each box 14 placed end to end in the direction of the length of the section is formed by a succession of boxes juxtaposed in the direction of the width of said section, said boxes being secured to each other by appropriate means .
  • Each box 14 can be formed by a thin "U" shaped wall 15 which can be fitted onto the wall of the adjacent box, as shown in FIG. 4.
  • the boxes 11 or 14 of the lateral end module 10a are closed by a thin vertical wall 16 which fits into the wall in the shape of a "U" 15 constituting said boxes.
  • the walls of the boxes 11 or 14 constituting the modules 10a, 10b, 10c ... as well as the base plate 4 are a light material of low density and high resistance.
  • This material is a composite material made of carbon fibers or glass fibers and having, for example, a honeycomb structure.
  • This arrangement makes it possible to make modular works of great length and of high strength having a volume-to-weight ratio as low as possible.
  • the spans according to the invention therefore have qualities of robustness, mechanical solidity and high resistance and have a very particular aptitude for the speed of installation, but also a lightness facilitating their transport and their implementation.
