A Steel Composite Bridge Having Steel Plates Connected by Using Concrete Cross Beams and Its Constructing Method

摘要

PURPOSE: A steel composite bridge which connects steel using a concrete beam, and a construction method thereof are provided to reduce the construction period and cost by connecting steel girders without welding or bolting. CONSTITUTION: A steel composite bridge(1) which connects steel using a concrete beam comprises multiple steel girders(10), connections(17), and a cross beam. The steel girders are manufactured to a simple bridge, and installed in each span. The connections are formed on the surface of webs(12). The webs are formed in the end parts of each steel girder. Multiple shear connectors(15) are protruded from the connections. The cross beam integrally couples each connections of the steel girders closely arranged each other.
