RAHMEN BRIDGE AND CONSTRUCTING METHOD THEREOF

摘要

PURPOSE: A rahmen bridge of a corner part negative moment reducing structure using strong coupling after a temporary hinge structure and a construction method thereof are provided to reduce negative moment by maintaining the simple supported form of a longitudinal girder with the application of loads due to the placing of concrete to a bottom plate. CONSTITUTION: A rahmen bridge of a corner part negative moment reducing structure using strong coupling after a temporary hinge structure comprises a rotary hinge member at both sides of both ends of a longitudinal girder (1). The top surface of a bridge wall (2) is installed with a rotary support (20). A joint rod (23) penetrates the rotary support. The rotary hinge member is integrated with an anchorage (13) at both sides of the end of a prestressed concrete panel (11).
