Definitions

  • the present invention relates to a machine for producing uniaxial reinforcing steel mats comprising a mat former, at least one reinforcing steel rod storage magazine and at least one reinforcing steel rod entry disposed laterally of the mat former, the mat forming apparatus being adapted to join reinforcing steel rods to at least one fastener tape.
  • Reinforcing steel mats are used in reinforced concrete construction to improve the static properties of concrete slabs, such as slabs or floor slabs, and have the task of absorbing tensile forces via their reinforcing steel bars and thus supplementing the compressive strength of the concrete so that the load-bearing capacity of concrete slabs is improved.
  • Such reinforcing steel mats are made of special reinforcing steel, wherein the reinforcing steel bars have a round cross section and a ribbed surface.
