CONSTITUTION: A vertical hole B is excavated on the ground A and a steel pipe 2 is inserted into the upper portion of the vertical hole B. Projections 3 such as stud are planted on the inner surface 2a of the steel pipe 2. Then, the lower portion 4a of a column 4 having a base plate 8 fixed at the lower end is arranged in the vertical hole B at a penetration depth H. The column 4 and the steel pipe 2 is positioned using supporting members 10. Then, the concrete 6a and 6b are cast into the clearance between the steel pipe 2 and the column 4 to integrate the column 4 and the foundation 1.
