STEEL PIPE PILE JOINT, STEEL PIPE PILE, AND CONSTRUCTION METHOD OF STEEL PIPE PILE
To provide a steel pipe pile joint and a steel pipe pile at a low cost which have high strength and excellent buckling resisting performance.SOLUTION: A tubular joint mounted on an end part of a steel pipe pile and including mechanical means for mutually connecting the steel pipe piles includes a weld part extending in a pipe axis direction. It has a component composition in which Ceq is equal to or greater than 0.20 and equal to or less than 0.60. The width in the pipe circumferential direction of a melting solidification part at the weld part is equal to or greater than 1.0 μm and equal to or less than 1000 μm across the entire thickness of the pipe.SELECTED DRAWING: Figure 1
【課題】高強度かつ耐座屈性能に優れた鋼管杭継手および鋼管杭を安価に提供する。【解決手段】鋼管杭の端部に取り付けられ前記鋼管杭を相互に連結するための機械的手段を備える管状の継手であって、管軸方向に延びる溶接部を有し、Ｃeqが０．２０以上０．６０以下である成分組成を有し、前記溶接部における溶融凝固部の管周方向の幅が管全厚にわたり１．０μｍ以上１０００μｍ以下である。【選択図】図１
