BStG - wire gauge for reinforcement mesh

Reinforcement bars have been in reinforced concrete for a long time known and also introduced on a large scale. For these reinforcement bars, the bar diameters are determined according to a special one Burchiaesser range selected. This series is e.g. 4.0, 4.2, 4.6, 5 »Q, 5.5, 6, ο to 12, ο mm. Me diameter are adhered to by cold drawing with solerances of + 0.08 am.

The need often arises on construction sites that supplied reinforcement meshes with regard to their dimensions and bar diameter with the according to the static calculations Compare the necessary steel cross-sections. The bar spacing can easily be checked with meter measurements, while slide gauges and micrometer screws must be used for the rod diameter. These measuring tools are but mostly not available on the construction sites. Even if they can be obtained, there are difficulties in handling, as the reading of these measuring tools requires certain knowledge that the construction workers do not have feature. A further complicating factor is that these measuring tools are very expensive and they are also too much for construction site use are sensitive. Their acquisition is therefore usually rejected without a usable replacement being available were.

It is now proposed in the invention to create a "special brace gauge for the component, with which the diameter of the bars of reinforcement mat ^,! Are controlled.
