STEEL PIPE PILE AND STEEL PIPE SHEET PILE SERIES, AND DETACHABLE FOLLOWER FROM STEEL PIPE PILE AND STEEL PIPE SHEET PILE BELONGING TO THE SAME
To provide a series of steel pipe piles and steel pipe sheet piles in which axial alignment is easy when fitting the same follower and mechanical joints provided in steel pipe piles having different diameters.SOLUTION: It has a steel pipe group in which a mechanical joint J having a size corresponding to the diameter of a steel pipe S and the thickness of the steel pipe is provided at the end of the steel pipe, the mechanical joint J has a pin joint 20 provided on one steel pipe S1 and a box joint 10 provided on the other steel pipe S2 among the two steel pipes S (S1, S2) connected to each other, a load transfer key 30 is provided which prevents the pin joint 20 and the box joint 10 from being separated in the axial direction of the steel pipe S by engaging an outward groove portion provided in the pin joint 20, and an outward reference surface 26 is provided on part of an outer peripheral surface 21 of the pin joint 20 in which the distance from the axial center of the steel pipe S1 is set to be constant regardless of the diameter and thickness of the steel pipe S1 in which the pin joint 20 is provided.SELECTED DRAWING: Figure 1
【課題】同じヤットコと、径が異なる鋼管杭に設けられた機械式継手と、を嵌合するときに軸心合わせが容易な鋼管杭・鋼管矢板のシリーズを提供する。【解決手段】鋼管Ｓの端部に、該鋼管径及び鋼管厚みに応じた大きさの機械式継手Ｊが設けられ、機械式継手Ｊは、互いに連結される二本の鋼管Ｓ（Ｓ１、Ｓ２）のうち、一方の鋼管Ｓ１に設けられたピン継手２０と、他方の鋼管Ｓ２に設けられたボックス継手１０とを有し、ピン継手２０に設けられた外向き溝部に係合することによって、ピン継手２０とボックス継手１０とが、鋼管Ｓの軸心方向に離れることを防止する荷重伝達キー３０が設けられるとともに、ピン継手２０の外周面２１の一部に、該ピン継手２０が設けられる鋼管Ｓ１の鋼管径及び鋼管厚みによらずに該鋼管Ｓ１の軸心からの距離が一定に設定された外向き基準面２６が設けられている鋼管群を有する。【選択図】図１
