<p>PROBLEM TO BE SOLVED: To provide a joint structure of a steel pipe pile which can perform efficient connecting work of a first steel pipe pile and a second steel pipe plie, improves the structural resistance of a joint as a whole, and can suppress material costs and manufacturing costs of the joint as a whole.SOLUTION: This invention relates to a joint structure 7 of a steel pipe plie which connects a first steel pipe pile 1 and a second steel pipe pile 2 in an axial core direction Y. The joint structure 7 of the steel pipe plie applied with this invention comprises an external fit end part 3 and an internal fit end part 5 in a pair which can be fit to each other. The external fit end part 3 has an external fit crest part 31, an external fit groove part 32, and an external fit trough part 33. The internal fit part 5 has an internal fit crest part 51, an internal fit groove part 52, and an internal fit trough part 53. Side faces of the external fit groove part 32 and the internal fit groove part 52, which extend to the axial core direction Y, are formed into tapered shapes which incline to an axial core orthogonal direction X. Side faces of the external fit trough part 33 and the internal fit trough part 53, which extend to the axial core direction, are formed into straight shapes which extend to the axial core direction in substantially parallel therewith.</p> |
