TEMPORARY BRIDGR STRUCTURE USING GIRDER WITH UPPER REINFORCING BEAM AND TEMPORARY BRIDGR CONSTRUCTION METHOD USING THE SAME

摘要

A temporary bridge installation structure using a mold in which the top steel beam is formed and a construction method thereof are provided to make the economic design of cross sections possible and to minimize the construction costs by maximizing the cross sectional rigidity of the mold. A construction method of temporary bridge installation structure using a mold in which the top steel beam is formed comprises following steps: a step which sets up a temporary lower structure(400) including a temporary bent; a step which sets up a mold(100) which is integrated with an upper steel beam(200) between the temporary lower structures; a step which sets up a plurality of lining boards(500) in the traverse direction between molds; and a step which sets up the lining board in the lateral part of the top steel beam.
