CONSTURUCTION METHOD FOR COMPOSITE GIRDER

摘要

PURPOSE: A continuous construction of a stable and excellent structure for a bridge is provided to resist the negative moment of the bridge supporting post. CONSTITUTION: A continuous construction of a stable and excellent structure for a bridge comprises a step of forming multiple steel girders(200) formed during the manufacturing step of a composite girder(100); steel materials and upper plate concretes applied on the top of the multiple steel girders; a step for positioning the support of the bridge post of the set up steel girder; and multiple composite girders in the abutment(30) or in the multiple bridge piers(40) where multiple composite girders are alternatively united.
