CONSTRUCTION METHOD OF A BRIDGE USING TEMPORARY INSTALLATION BRACING

摘要

PURPOSE: A bridge construction method using a temporary installation bracing replacing a cross beam is provided to construct a bridge by reducing the load of the superstructure of a bridge. CONSTITUTION: A bridge construction method using a temporary installation bracing replacing a cross beam(21) is as follows. A support girder, in which a diaphragm is included, is established on the top of the bridge post. A main girder(20b) has a temporary installation bracing. The shear strength of the main girder is reinforced. The concrete is poured in and forms the bottom plate. The temporary installation bracing is disassembled after the curing of the concrete.
