Earthquake resistance reinforcing device for life line pipe conduit



(57)【要約】 【目的】 特に既設のライフライン管路に備えている管 継手部を耐震性に優れた構造に変換できる耐震強化装置 を提供することを目的とする。 【構成】互いに対向して配置される一方の配管2と他方 の配管3とに跨ってスリーブ継手1の外周全体を包囲す る割り型の耐震補強カバー20を有し、該カバー20 は、管軸方向におけるどちらか一方の端部または両端部 を上記配管2,3の外周面に対し摺動可能に気密嵌合 し、地震等による配管の抜けだしを防止するように構成 した。
PURPOSE: To provide an earthquake resistant reinforcing device whereby a pipe joint part particularly provided in an existing life line pipe conduit can be changed into a structure excellent in earthquake resistance. CONSTITUTION: A device has a split type earthquake resistance reinforcing cover 20 of surrounding a peripheral total unit of a sleeve joint 1 astride one pipe 2 and the other pipe 3 arranged to be opposed to each other, and in this cover 20, either one of an end part or both end parts in a pipe axial direction are slidably and air-tightly fitted relating to a peripheral surface of the pipes 2, 3, to prevent the pipe from coming off due to an earthquake or the like.
