TIED ARCHED P.S.C GIRDER FOR BRIDGE AND CONSTRUCTION METHOD FOR BRIDGE BY IT

摘要

PURPOSE: one kind hitting arch form P.S.The method of C (PreStressed) concrete box girder bridges and bridge uses the application crane structure method, and makes to construct the additional erection load on Longspan Bridge by obtaining sufficient intensity. ;CONSTITUTION: one kind hitting arch form P. S.C beams (1) include lower flange, and web, the tendon (8) of mounting hole (7) is longitudinal to enhance bar (9), horizontal stirrup (10) and cable (4). The beam is formed as T shapes shape steel rolled stock, and wherein upper flange and web upper surface unit area are omitted. Assembling additional web reinforcing bar is omitted, and exposes T section on the upside of the longitudinal direction reinforcing steel bar and the horizontal reinforcement bar disc arrived in ready pass through of girder. The P. S.C manufactures beam P after manufacturing field, and the additional construction of support loads settle. In predetermined position S.C beams use crane. Web concrete and upper flat plate (12) are placed on block, pass through the beam being gradually integrated. ;The 2013 of copyright KIPO submissions
