Steel composite PSC truss U-shaped simply supported girder bridge and continuous beam bridge
The invention refers to a steel composite PSC truss U-shaped simply supported girder bridge, comprising a U-shaped girder (40), a abutment bearing concrete partition block (50), a half-prefabricated bridge deck slab (60), first and second internal stretching PS steel wires (W1,W2), first and second external stretching PS steel wires (W3,W4), first and second internal stretching PS steel wire anchor block and anchorage zones (71a,71b) and a pair of first and second external stretching PS steel wire anchor block and anchorage zones (73a,73b). According to the invention, the structure and stretching mode of the steel composite PSC truss U-shaped girder truss joints, anchor block and anchorage zones, saddle shapes and PC steel wires of the prior art are improved, and the efficiency is increased; in addition, compared with the PSC U-shaped girder of the prior art, the steel composite PSC truss U-shaped simply supported girder bridge reduce the usage amount of concrete, and the weight of the girder; compared with a steel box girder or a U-shaped steel girder, the steel composite PSC truss U-shaped simply supported girder bridge reduce the usage amount of steel, and increases economic benefits.
