Construction method of rising member, foundation structure and foundation structure

摘要

PROBLEM TO BE SOLVED: To provide a rising member, a foundation structure and a construction method of a foundation structure capable of improving workability for constructing a foundation structure. SOLUTION: A rising member 1 is configured to include a square steel pipe 20. The square steel pipe 20 has higher rigidity than a steel material having an open cross section. Therefore, when the square steel pipe 20 is used as a rising member of the foundation structure 100, the reinforcing structure and the level adjustment portion can be reduced. Specifically, even when one square steel pipe 20 bridges between the nodes 15 and the nodes 15 without being reinforced by reinforcing metal fittings or the like, the rising member 1 is placed between the nodes 15 and the nodes 15. It can maintain a straight stretched state without bending. [Selection diagram] Fig. 1
