PROBLEM TO BE SOLVED: To provide a steel pipe diameter change ring capable of welding a steel pipe such as a steel pipe pile or a ground reinforcement pile body with a selected steel pipe of a different size while reducing the cost for the steel pipe pile and ground reinforcement pile body.SOLUTION: A steel pipe diameter change ring R21 is used for welding Y21, Y22 a large diameter steel pipe P22 and a small diameter steel pipe P21. The steel pipe diameter change ring R21 has a large diameter end for being welded with a large diameter steel pipe, and a small diameter end for being welded with a small diameter steel pipe selected from two or more different sizes. The steel pipe diameter change ring R21 has a guide rib for allowing centering between the large diameter steel pipe and the small diameter steel pipe without depending on the thickness of the steel pipe.SELECTED DRAWING: Figure 2
【課題】本発明は、鋼管杭や杭状地盤補強体の鋼管にサイズの異なる鋼管を選択して溶接することを可能として、鋼管杭や杭状地盤補強体のこすと削減を図る事を目的とする。【解決手段】大径鋼管Ｐ２２と小径鋼管Ｐ２１を溶接Ｙ２１、Ｙ２２する鋼管径変換リングＲ２１で、大径鋼管を溶接することのできる大径端部と２つ以上の異なるサイズから選択された小径鋼管を溶接することのできる小径端部を備え、鋼管の肉厚に左右されることなく大径鋼管と小径鋼管のセンタリングを可能とするガイドリブを有することを特徴とする【選択図】図２
