PROBLEM TO BE SOLVED: To provide a steel pipe pile joint structure capable of improving verticality in the case of junction and facilitating joint work (welding or bolt press-fitting) irrespective of steel pipe piles having the different or same diameter.SOLUTION: An inventive steel pipe pile joint structure is the steel pipe pile joint structure 1, 1A, 1B, 1C, 1D for joining a lower steel pipe pile 2 installed first on a foundation and an upper steel pipe pile 4 to be connected to the upper end of the lower steel pipe pile 2 to each other. The steel pipe pile joint structure is constituted of: a lower pile special part 3 integrally joined to the upper end of the lower steel pipe pile 2 and having an outer diameter identical to that of the lower steel pipe pile 2; and an upper pile special part 5 including an outer fitting part 52 having an inner diameter substantially identical to the outer diameter of the lower pile special part 3 for externally fitting to the lower pile special part 3, and an upper end fixing part 53 having an inner diameter substantially identical to the outer diameter of a lower end 43 of the upper steel pipe pile 4 for externally fitting to the lower end 43 of the upper steel pipe pile 4. |
