摘要

PROBLEM TO BE SOLVED: To provide an auxiliary piece for executing the piping in a concrete building skeleton capable of temporarily fixing a sleeve pipe and fixing a receiving mold in the closed condition of the piping hole, and a piping execution method of a concrete building skeleton using the auxiliary piece. ;SOLUTION: In an auxiliary piece, three or more metallic fixing leg parts 3 are arranged in the same direction as the axis of an annular part with equal intervals on a metallic annular part 2, and in each fixing leg part, a fixing part 4 is formed on one end and a foldable metallic wire part 6 of the desired length is formed on the other end in an extended manner. In the piping execution method, the auxiliary piece is integrated in an embedded manner with a piping hole 11 surface in a skeleton 10 except the metallic wire part, and a pair of molds held by the metallic wire part hold a pipe 15 piercing the piping hole, and one piping holes is closed, and a clearance 16 to be regulated between the piping hole and the pipe is closed by a repairing material.;COPYRIGHT: (C)1998,JPO
