PIPE JOINT, UNDER-PEENING METHOD USING THE PIPE JOINT, AND STRUCTURE EQUIPPED WITH THE PIPE JOINT
To omit welding work when connecting steel pipes in an under-peening method.SOLUTION: Prepared is a pipe joint for a steel pipe having a connection portion inserted into the steel pipe and a flange portion 5 bulging outwardly to an outer periphery from the connection portion, wherein a projection length L1 of the connection portion from the flange portion 5 is a length of 0.5 times or more of a diameter D of the steel pipe. A first steel pipe 100 is added to a second steel pipe 200 installed under a building via the pipe joint to form a structure composed of the first steel pipe 100, a joint 1, and the second steel pipe 200. Welding is not required to form the structure.SELECTED DRAWING: Figure 2
【課題】アンダーピーニング工法において鋼管を連結する際に溶接作業を省略する。【解決手段】鋼管へ挿入される接続部及び該接続部から外周外方へ膨出する鍔部５を備える鋼管用の管継手であって、鍔部５からの接続部の突出長さＬ１が鋼管の直径Ｄの０．５倍以上の長さを備える管継手を準備する。建物の下に設置されている第２鋼管２００へ管継手を介して第１鋼管１００を継ぎ足して第１鋼管１００－継手１－第２鋼管２００からなる構造体を形成する。構造体を形成するにあたり溶接は不要である。【選択図】図２
