POSITION ADJUSTABLE JOINING STRUCTURE OF STEEL PIPE PILE AND ANCHOR REINFORCEMENT

PROBLEM TO BE SOLVED: To facilitate joining work by easily avoiding interference with a foundation reinforcement by varying a joining position of an anchor reinforcement to a steel pipe pile. SOLUTION: A T-shaped cross-sectional annular bracket 2 is welded to a pile head part 1a of the steel pipe pile 1. A recessed part 6a of gripping metal fittings 4 engages with a projecting part 3 on the outer periphery of the bracket 2. The gripping metal fittings 4 are radially arranged in large numbers on the periphery of the pile head part 1a. A position can be adjusted in the peripheral direction. The anchorage reinforcement 7 is fixed to the respective gripping metal fittings 4 via a joint sleeve 12 by a relay male screw member 9.
