METHOD FOR CONSTRUCTING MULTI-INTER-DIAMETER CONTINUOUS COMPOSITE GIRDER

摘要

PROBLEM TO BE SOLVED: To provide a method for constructing a multi-inter-diameter continuous composite girder capable of building a continuous steel-concrete composite girder at a low cost in a short period. SOLUTION: When constructing the multi-inter-diameter continuous composite girders for constructing steel-concrete composite girders A integrally having concrete girders while being unified with at least one flanges of steel girders composed of H steel on two diameters or more of piers 4 in a state that the steel-concrete composite girders A are connected in the extension direction, girders 10 are constructed as being continued in the number of the predetermined piers to be built while side loaders 20 are installed on each pier 4. A predetermined number of the steel-concrete composite girders A constructed among multi-diameters on the girders 10 are sent out to specified places of where the composite girders A are built, and sections among each steel-concrete composite girder A are connected on the girders 10 in this case. One multi-inter-diameter continuous composite girder B connected in a predetermined multi-inter-diameter construction length is assembled, and the continuous composite girder B is built at a specified place on the piers 4 by the side loaders 20 in this case.
