<p>PROBLEM TO BE SOLVED: To enable a circular pipe and also an egg-like pipe having a cut-opening part becoming a similar shape to that of a silhouette line of an egg to be fitted due to a variation in size of diameter of a pipe under vibration of a freight train or the like running at a bridge, variation in length and pipe diameter caused by variation in in-pipe pressure by water hammering and variation in thickness of a pipe accompanying with variation in environmental temperature.SOLUTION: Anchor bolts 12 buried in a concrete foundation 2 are passed through elongated holes 21 formed at leg parts 20 at both ends and fixed by fixing means such as double nuts 13 and the like. Standing parts 30 stood up at a right angle from inside the leg parts 20 hold a pipe member receiving part 40 curved at a prescribed curvature factor between the standing parts. The standing parts 30 and the pipe member receiving part 40 are formed by an integral plate member, a tangent line between the standing parts 30 and the pipe member receiving part 40 is bent at an angle of about 20 to 60 degrees, and a long hole 45 passing in a width direction of the standing parts 30 is arranged at its crossing parts. The pipe member receiving part 40 integral with the standing parts 30 is bent to increase its height, resulting in that even if the long hole 45 is formed there, its strength is set high due to bending of the pipe member receiving part 40, its deformation is hardly generated and its breakage is also hardly produced.</p> |
