MAIN CONCRETE GIRDER AND CROSS STEEL BEAM CONSTRUCTING METHOD AND STRUCTURE THEREOF IN CONCRETE GIRDER BRIDGE

摘要

PURPOSE: A main concrete girder and cross steel beam constructing method and the structure thereof in a concrete girder bridge are provided to improve constructing and economic properties by simply assembling the steel beam with the main girder with bolts. CONSTITUTION: An embedded sleeve(11) is buried in an installed portion of a cross steel beam when a main concrete girder(1) is produced. In installing the main concrete girder on a pier(3), the cross steel beam(4) is combined with the embedded sleeve with bolts(16). Thereby, a term of work and accidents are reduced by minimizing processes to be processed on a construction site.
