<p>PURPOSE:To omit the work of bending cables, to be snake-laid, by specified curvature beforehand. CONSTITUTION:Cables 1 are supported by fixing cleats 11 arranged beforehand at specified intervals, and at their intermediate parts the cables 1 are pushed by the use of elastic members 14 in a direction perpendicular to their laid direction. If the cables 1 expand by heat, the cables 1 are curved forcedly in the pushing direction of these elastic members 14, and the thermal expansion is absorbed, as the forces by these elastic members 14 are being applied to the cables 1. Consequently, the thermal expansion or contraction of the cables is absorbed, even if the cables are laid without bending them into a snakelike shape beforehand, and it becomes possible to facilitate the laying work.</p> |
