Zusammenfassung:PURPOSE:To reduce the cost of a construction structure when a tank roof is built and to shorten a term of works for construction of a tank. CONSTITUTION:After a body 1 in the shape of a cylinder with a bottom comprising a side wall 4 and a bottom slab 5 is completed, and a support frame 6 is erected approximately to the same level as that of the upper end part of the side wall by assembling construction materials. Long precast beams 8 are radially constructed in a manner that two ends are supported to the upper end surface of the side wall and a support frame to form a roof frame. Concrete plates are disposed between the adjoining roof frames to close an upper opening. Concrete is placed in a position surrounded with the end parts of a plurality of precast beams on the concrete plate and the support frame.
