PROBLEM TO BE SOLVED: To increase the strength of the junction between a steel pipe pile and a column joined to the top of the pipe in a one-column, one-pile footing and to simplify the work of joining them together. ;SOLUTION: A steel pipe pile 1 is buried into the ground up to a position where the upper end of the steel pipe pile 1 attains a predetermined depth, and concrete 4 is placed inside and around be steel pipe pile 1 up to a position higher than the upper end of the steel pipe pile 1. After the concrete 4 has hardened, upper extra concrete 4a is removed from the upper end position of the steel pipe pile 1, and a sheath pipe 5 is joined to the top of the steel pipe pile 1. A column 6 is inserted into the sheath pipe 5. Thereafter, concrete 7 is placed in the sheath pipe 5 to fix the sheath pipe 5 and the column 6 together.;COPYRIGHT: (C)1999,JPO
