PROBLEM TO BE SOLVED: To provide a technology of excellent workability using a steel pipe pile of a large bearing force as a foundation in a simpler and inexpensive joint structure and a joint method of a steel pipe pile and a column member. SOLUTION: The joint structure of the steel pipe pile and a pair of pliers in construction by a rotary press-in pile method comprises a ring flange 2 stuck to the upper end of the steel pipe pile 1, and the pliers comprising a connecting flange 61 formed at the lower end of a cylindrical body 60 formed with almost the same diameter as the steel pipe pile 1. The ring flange 2 and the connecting flange 61 are joined and fixed to perform construction by the rotary press-in pile method. After construction, the pliers are removed from the steel pipe pile 1, and the ring flange 2 stuck to the upper end of the steel pipe pile 1 is used as the foundation of a temporary iron tower, a scaffolding iron tower, or the like.
