The present invention achieves simplification and a reduction in the cost of a structure for connecting a pair of steel pipes. This joint mechanism for a pair of steel pipe piles 1A, 1B is provided with: an inner joint 10A provided in steel pipe pile 1A; an inner joint 10B; an outer joint 20 that is provided around the inner joint 10A of steel pipe pile 1A and the inner joint 10B of steel pipe pile 1B, spanning said joints; and a key member 30 for preventing the pair of steel pipe piles 1A, 1B from moving relative to each other in a steel pipe pile 1 length direction. The outer joint 20 is provided with an opening 22 (22A, 22B) for inserting, from the outer peripheral surface of the outer joint 20, a divided key member 31, which constitutes a key member 30, into a key groove which is composed of outward-facing peripheral grooves 13 (13A, 13B), which are provided in the outer peripheries of inner joint 10A and inner joint 10B, and inward-facing peripheral grooves 23 (23A, 23B), which are provided in the inner periphery of the outer joint 20 and face the outward-facing peripheral grooves 13 (13A, 13B). |
