ABSTRACT:
The invention relates to reinforcement grids for steel concrete construct and consisting of longitudinal transverse rods crossing one another which, at some or all of their crossing points, are connected by pieces of binding wire looped around the rods and closed by twisting their free ends together. In order to give the grid rectangular stability, within each mesh of the grid, or within each rectangular mesh group comprising a number of adjacent meshes, the binding wire loops at the four crossing points of the rods defining the mesh or mesh group are looped around the rods defining the mesh or mesh group are looped around the rods so that the planes of half the loops are 90.degree. from the planes of the remaining loops, and the loops in each direction are uniformly present in the grid.
