BRIDGE CONSTRUCTION METHOD USING HYBRID PSC GIRDER

摘要

PURPOSE: A method of constructing a bridge using a hybrid PSC(Pre-stressed Concrete Beam) girder is provided to reduce the weight of the upper and lower structures of a bridge since the horizontal gap of the PSC girder is widely arranged. CONSTITUTION: A method of constructing a bridge using a hybrid PSC girder comprises next steps. A transverse beam(200) is installed between the PSC girder and its side in a transverse direction. A plurality of transverse beams are installed to be separated in a longitudinal direction. A transverse secondary beam(100) is installed between the transverse beams in parallel to the PSC girder(10) in a longitudinal direction. A transverse point(A) is formed on the bottom of a slab by the transverse secondary beam. The slab is formed to make contact with the tops of the PSC girder, the transverse beam, and the transverse secondary beam.
