Lagging mat for mine support

The invention relates to a lagging mat in which the longitudinal wires lie in pairs closely adjacent to one another and every pair of longitudinal wires has, as a coupling head, a transverse deviation, which forms a T-beam, and, as a coupling cutout, a T-shaped eyelet, the eyelet having a transverse...

Summary:The invention relates to a lagging mat in which the longitudinal wires lie in pairs closely adjacent to one another and every pair of longitudinal wires has, as a coupling head, a transverse deviation, which forms a T-beam, and, as a coupling cutout, a T-shaped eyelet, the eyelet having a transverse cutout, which forms a T-beam, for passing-through of the coupling head of the lagging mat to be adjoined, and a longitudinal curved projection, which forms a T-web, as a support for the hooked-in coupling head and for passing-through of its pair of longitudinal wires. By this means, a lagging mat, is realised which is particularly simple in terms of manufacture and installation a mat joint fastening and has of a high tensile strength.
