FIXING STRUCTURE OF ANCHOR REINFORCEMENT TO STEEL PIPE PILE HEAD, AND STEEL PIPE PILE WITH ANCHOR REINFORCEMENT

PROBLEM TO BE SOLVED: To provide a technology for fixing an anchor reinforcement to the head of a steel pipe pile, effective in reducing a construction cost and improving welding strength to the outer peripheral part of the steel pipe pile by a simple method. SOLUTION: A U-plate 2 formed by bending a plate in approximately U-shape is welded to the head outer peripheral surface of the steel pipe pile 1 while abutting beveled parts 11, 12 formed of inclined faces formed at the open ends of the U-plate 2, and a screw part of the anchor reinforcement is inserted through the internal space 13 of the U-plate 2 and clamp-fixed by nuts from the upper and lower sides.
