CONSTRUCTING METHOD OF COMPOSITE STRUCTURE

PROBLEM TO BE SOLVED: To improve workability by projecting a column steel frame, to which a reinforced beam in the inter-beam direction is built, in specified length from height, in which a beam in the girder direction is disposed, supporting a temporary beam at the upper ends of both column steel frames and constructing the reinforced beam under a suspended state. SOLUTION: In a composite structure 15, in which beams in the girder direction are formed in steel-framed beams 12 or steel-framed reinforced beams and a beam in the inter-beam direction 13 is formed in a reinforced beam 14, coin steel frames 16 are disposed in upright while the column steel frames 16 are projected in specified length from height, in which the steel-framed beams 12 in the girder direction are arranged. A temporary beam 17, from which the beforehand assembled reinforced beam 14 in the inter-beam direction 13 are hung down, is hung up and placed at the upper ends of both column steel frames 16 projected in specified length by a crane, and the reinforced beam 14 is built at a fixed place. Hanging jigs 18 supported to the temporary beam 17 consist of angle materials 19 installed to the temporary beam 17 and hang bolts 20 mounted at both ends of the angle material 19, and the upper end reinforcement of the reinforced beam 14 is supported. Accordingly, the erection works and removing works of supports need not be conducted, and workability and safety can be improved.
