PURPOSE:To prevent the levitation of a semi-underground depository by a method in which protruded flanges for connection are provided to the joints of halve bodies, and anchors whose lower ends are buried in the foundation below the body, are connected to fixing metals attached to the flanges. CONSTITUTION:Protruded flanges 11 are formed on the edges of side openings as joints of both halve bodies, and both flanges 11 are joined with bolts and nuts 14 to form a body 1. Vertically long cylindrical fixing metals 3 are attached to the body 1 with bolts and nuts 14, and vertically long couplers 5 whose upper end is threaded and the lower end is bent are inserted into the cylinder. The upper ends of anchors 4 whose lower ends are buried in the foundation 9 provided below the body 1 are connected with the lower ends of the couplers 5, and the upper ends of the couplers 5 are clamped with washers 6 and nuts 7. The body 1 can thus be strongly fixed to the foundation 9. |
