continuous bridge construction method using the lateral beam and preflex-girder

摘要

PURPOSE: A construction method for a continuous bridge using a horizontal beam and a main girder(preflex beam) is provided to enhance bending strength, to cut down manufacturing costs and to construct a continuous bridge in a long span. CONSTITUTION: The construction method for a continuous bridge using a horizontal beam and a main girder(preflex beam) comprises the steps of: installing a horizontal beam(200) horizontally on an abutment or a pier; installing a main girder(100) vertically between the abutment and the pier; connecting a joint between the horizontal beam and the main girder using a joint unit; forming joint concrete(400a) of the horizontal beam and the main girder, a web of the main girder, and concrete of a support; and placing/curing slab concrete on the horizontal beam and the main girder.
