Abstract
A protective mesh, especially for rockfall protection or to stabilise a layer of soil, is braided out of helically curved wires (11, 12, 13, 14, 15, 16). Rhomboidal meshes (17) are formed and in each case two adjacent helical wires (11, 12, 13, 14, 15, 16) are flexibly held together. The protective mesh (10) has a thickness which amounts to a multiple of the thickness of the wire. In at least some of the braided pairs of wires (11, 12, 13, 14, 15, 16), an essentially straight longitudinal reinforcement element (31, 32, 33, 34, 35) is guided through the coupling area (A) of the two helical wires, causing the rhomboidal meshes (17) to be divided into triangular meshes (17a, 17b). In these crucial areas of force transmission of the protective mesh, there are now three instead of two wires meeting, as the result of which the force absorption capacity of the protective mesh is substantially increased.
