PURPOSE:To easily construct a basement having excellent stiffness and excellent water proofness by joining a superstructure consisting of an integrally molded FRP ceiling and flanges provided in the peripheral portion of the ceiling with a substructure consisting of a floor and flanges provided in the peripheral portion of the floor. CONSTITUTION:A superstructure 1 is integrally molded of FRP and provided with a ceiling 6 and flanges 4 formed in the peripheral portion of the ceiling 6. Also, a substructure 2 has a shape almost symmetrical to the superstructure and consists of a floor 9 and flanges 5 formed in the peripheral portion of the floor 9. The substructure 2 is set underground 90, the superstructure 1 is superposed on the substructure 2, and the flanges 4 and 5 are clamped with bolts. The supperstructure 1 and the substructure 2 may be connected with each other on the ground in advance, and an inlet part may be connected even in any construction stage. |
