CONSTRUCTION METHOD FOR MULTI-STORIED SUSPENSION STRUCTURE

PURPOSE:To make it possible to assemble girders and a suspension material installed between the upper ends of core posts at the lower ends of the core posts and to enable the construction of the girders and suspension material to be carried out simply and safely. CONSTITUTION:A postless large space section S is formed in the lower layer sections of a pair of core posts 14 erected on both sides of a station 26 to construct the artificial foundation 28. Lift up systems are mounted on the upper ends of the core posts 14, and truss girders 18 and a suspension material 20 are subsequently assembled at the lower ends of the core posts 14 while lifting up them. After the completion of assembly, the truss girders 18 and suspension material 20 are lifted up to the upper ends and are fixed. After that, a suspension stage 32 is located at the lower side of the suspension material 20 and is assembled between the core posts 14. The suspension stage 32 is used as a scaffold, and post materials 22 and beam materials 24 are constructed downward while re-shoring subsequently the suspension stage 32 downward.
