In order to be able to lay reinforcement grids for reinforced concrete in formations of mats by the selection of one of a number of edge overlappings which can easily be checked after the laying of the grids, each grid is formed, on one or both sides of inner longitudinal wires (1) occupying the middle region of the grid and arranged at equal mutual spacings (a), with a number of longitudinal members (2, 3, 4) distinguishable from the longitudinal wires (1) and at greater mutual spacings (ka), of which at least one (2) preferably the innermost, is clearly distinguishable visually also from the rest of these longitudinal members (3, 4) whereby for a number of widths of overlap typical pictures of the overlap result. <IMAGE> |
