Definitions

  • the subject of the present invention is a transportable span intended in particular for crossing breaches by so-called heavy vehicles, for example by armored vehicles.
  • spans are generally either spans of the scissor type, or either simple spans in several abutable sections.
  • the scissor-type span comprises two or three elements which develop in rotation in a vertical plane around the common axis of two elements.
  • these spans can be placed either by means of an arrow or using a manipulator.
  • the sections are transported superimposed with respect to each other, then moved in translation by a manipulator which, after locking the sections, also serves for the removal of the span thus formed.
  • scissor-type structures or simple structures are generally formed by welded metal beams of large section or by lattice structures, so that the weight of the spans is important which does not facilitate their installation.
  • the invention therefore aims to provide a span for crossing gaps allowing to reconcile the qualities of robustness, solidity, mechanical strength and lightness.
  • 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 resistance, 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 section 1 is provided at each end with a spoiler 3 constituting the inclined access plane on said section for vehicles and also ensuring good stability of the assembly.
  • Section 1 is made up of several modules 10a, 10b, 10c ... (Figs. 1 and 2) juxtaposed and joined together by suitable means, not shown.
  • Each module 10a, 10b, 10c ... has a general parallelepiped shape whose upper face is slightly inclined to form a continuous curved profile.
  • each module 10a, 10b, 10c ... is formed by a longitudinal box 11 comprising two vertical thin walls 12a, 12b and two horizontal thin walls 13a, 13b.
  • the walls 12a, 12b and 13a, 13b can be nestable one inside the other or juxtaposable and assembled by suitable means.
  • Each module 10a, 10b, 10c ... can also be formed by a succession of boxes 11 juxtaposed in the direction of the width of the section 1 and joined together by appropriate means.
  • each module 10a, 10b, 10c ... is formed by a succession of boxes placed end to end in the direction of the length of said section 1 and secured to each other by appropriate means.
  • each box 11 or 14 is formed by a thin "U" shaped wall 15 which can be fitted onto the wall of the adjacent box.
  • the boxes 11 or 14 of the lateral end module 10a are closed by a vertical thin wall 16 which fits into the wall in the shape of a "U" 15 constituting said boxes.
  • the boxes 11 or 14 also rest on a base plate 4.
  • each module can be formed by a succession of boxes 14 placed end to end in the direction of the length of the section, and by a succession of boxes 11 juxtaposed in the direction of the width of said section, said boxes being joined together by appropriate means.
  • 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 of 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 bridges 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.
