PRESTRESSED SEGMENT CONCRETE GIRDER FOR BRIDGE AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A pre-stressed concrete beam for a bridge and a manufacturing method thereof are provided to be cost-efficiently applied to a long interval between columns without using a steel girder. CONSTITUTION: A pre-stressed concrete beam(100) for a bridge comprises a central segment concrete beam(1), end segment concrete beams(2), tensile members for connecting, cast-in-place concrete(160). The central segment concrete beam comprises a first block out part, a steel rod(120), and a steel wire anchorage for tension. The end segment concrete beams are extended from both sides of the central segment concrete beam. The tensile members are arranged in a sheath pipe passing through the end and central segment concrete beams in an arc shape. The cast-in-place concrete is placed in the first block out part and a second block out part.
