<p>One end of the tension-piece is attached to supports acting as anchor-bases fixed to the cladding-sheet, and the other end is attached to a cantilever beam which is firmly attached to the wall and forms an anchor-head. The tension piece is in the shape of a U-shaped clamp (30, 30', 30") each side of which (31, 31', 31"; 32, 32',32") has devices (37, 37', 37"; 38, 38', 38") for adjusting its length. a connecting-rod (36, 36', 36") joins the free ends of the clamp and is secured by nuts with spherical attachment faces.</p> |
