PROBLEM TO BE SOLVED: To reduce a construction period and a construction cost by streamlining a concrete construction and eliminate the need of repair work after completing the construction by eliminating the displacement of position between an opening part on a ground story building side and an entrance on a steel underfloor storage side. SOLUTION: In this construction method for the steel underfloor storage, a concrete foundation 3 for a ground story building, a cylindrical structural concrete wall 5, and an anchor 6 projected upward from the structural concrete wall 5 are formed around an excavated hole formed in an area where the ground story building is to be constructed. A fixed metal fitting 8 mounted on the steel underfloor storage 4 is inserted into the anchor 6 and the steel underfloor storage 4 is fixedly installed in the excavated hole 1 so that the lower surface of the fixed metal fitting 8 is brought into contact with the tip end face of the structural concrete wall 5. Then, a base concrete 16 at the bottom part of the steel underfloor storage 4 is formed integrally with a wall concrete 17 on the periphery thereof. COPYRIGHT: (C)2007,JPO&INPIT
