STEEL PIPE CONNECTION MECHANISM AND STEEL PIPE CONNECTION METHOD
PROBLEM TO BE SOLVED: To provide a steel pipe connection mechanism and a steel pipe connection method, which have good workability when a split key member is disposed in a key groove.SOLUTION: A steel pipe connection mechanism connects steel pipe ends that face each other of steel pipes, which are adjacent in steel pipe axial center direction, so that the pipes are prevented from being pulled out in the steel pipe axial center direction by a key member. The key member consists of multiple split key members 31 in a steel pipe circumferential direction. The split key member 31 has a connection mechanism capable of connecting adjacent split key members 31 with each other on both ends in longer direction of the split key member 31, and has longitudinal dimension L along longer direction that is shorter than horizontal width dimension H along the steel pipe circumferential direction of an opening 16 in communication with a key groove G in which the split key member 31 is disposed and longer than depth dimension of the opening 16.SELECTED DRAWING: Figure 3
【課題】分割キー部材をキー溝部に配置する際の作業性がよい鋼管連結機構及び鋼管連結方法を提供する。【解決手段】鋼管軸心方向に隣り合わされた鋼管の互いに対向する鋼管端部どうしをキー部材によって鋼管軸心方向に抜け止め状態に連結する鋼管連結機構であって、キー部材は、鋼管周方向で複数個の分割キー部材３１から構成され、分割キー部材３１は、分割キー部材３１の長手方向の両端部に隣り合う分割キー部材３１どうしを互いに連結可能な連結機構が備えられるとともに、分割キー部材３１が配置されるキー溝部Ｇに連通する開口部１６の鋼管周方向に沿った横幅寸法Ｈよりも短く、かつ、開口部１６の深さ寸法よりも長い長手方向に沿った長手寸法Ｌを有する。【選択図】図３
