Definitions

  • the invention relates to a reinforcement made of steel for curved structures, consisting of mutually perpendicular cross and welded together at the intersection points to a grid longitudinal and transverse wires.
  • Such steel wire meshes are used for many types of concrete reinforcement.
  • the invention aims to provide a reinforcing grid, which can be used as a reinforcement for the lining of tunnels, in particular for securing shotcrete, or other structures with arcuate or curved shape.
  • the reinforcement according to the invention of the type described in the introduction is characterized in that the longitudinal wires of the grid are provided at regular intervals with bends, and the transverse wires are arranged on the side of the bends respectively on both sides of a bend.
  • the grid is bendable in its longitudinal direction in a predetermined arcuate form, in which the bends are on the outside of the arch form.
  • FIG. 1 a plan view
  • FIG. 2 a side view of the reinforcement according to the invention
  • FIG. 3 the detail A of FIG.
  • the rectangular reinforcement grid shown in FIG. 1 consists of welded joints at their points of intersection. th longitudinal wires 1 and 2 cross wires made of steel. As the drawing in Fig. 3 shows, the transverse wires 2 are arranged in each case on both sides of regularly spaced bends 3.
  • the reinforcing grid can be made in any lengths and widths limited only by the production machines.
  • the grid is bent accordingly and applied to the tunnel wall, whereupon concrete is sprayed on.
  • a better longitudinal displacement of the longitudinal wires 1 is given.
  • longitudinal compressions for example, as a result of the rising rock pressure
  • the reinforcement grid is also suitable for other arched or curved structures.
