Trench wall support with horizontal cross bracing - has hinged feet and connecting pieces for ease of dismantling, transport and storage

摘要

The support for trench walls consists of two shutter panels linked by two horizontal braces (2), the ends of which are fastened to feed (4) rotating about axes (3) and attached to the inside face (6) of the shutter panels by connecting pieces (5). Rigid compression springs (7) are arranged between the two feet (4) and each brace (2) so that the latter is maintained perpendicular to the shutter panels. These springs give the support greater stability in spite of the fact that the braces ar hinged to the feet. The support is easily assembled by inserting the feet of the braces into the connecting pieces on the two shutter panels and can be equally easily dismantled facilitating both transport and storage.
