STEEL PIPE CONNECTION MECHANISM
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 a steel pipe axial center direction by a key member disposed in a key groove G formed along a steel pipe circumferential direction. A cover member 50, which prevents the key member disposed in the key groove G through an opening 16 from the outer space from being pulled toward the outer space through the opening 16, can be fitted on the opening 16 that allows at least a part of the key groove G in the steel pipe circumferential direction to be communicated with the outer space. A taper face 53, which is a non-transfer mechanism that does not transfer a load in the steel pipe axial center direction, is disposed at least at a part of the cover member 50 that is located in the key groove G facing 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、鋼管周方向に沿って設けられたキー溝部Ｇに配置した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、キー溝部Ｇのうち鋼管周方向の少なくとも一部を外部空間に連通する開口部１６に、外部空間から開口部１６を介してキー溝部Ｇに配置されたキー部材が、開口部１６を介して外部空間に抜け出ることを防止する蓋部材５０が取り付け可能であり、少なくとも、蓋部材５０のうち開口部１６に対向するキー溝部Ｇに存在する部分に、鋼管軸心方向に荷重を伝達しない非伝達機構であるテーパ面５３が備えられている。【選択図】図３
