STEEL PIPE FOR STEEL PIPE CONCRETE COMPOUND PILE, THE STEEL PIPE CONCRETE COMPOUND PILE, AND PILE HEAD COUPLING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a technique capable of bolt-joining a fixing reinforcement in a construction field even for a steel pipe concrete compound pile. SOLUTION: The steel pipe 1 for the steel pipe concrete compound pile includes an inner end plate 3 in an inside of a steel pipe end part serving as a pile head part, and is formed with a plurality of bolt holes 5 for bolt-joining the fixing reinforcement 23 onto a steel pipe part on a tip side of the inner end plate 3, at a prescribed interval along a steel pipe circumferential direction.
