Prestressed steel truss bridge
The invention discloses a prestressed steel truss bridge. The prestressed steel truss bridge is characterized by comprising an upper-portion stressed steel truss structure which comprises a truss piece, a bridge deck transverse distribution beam, a bridge deck steel plate, inclined struts, transverse ties, supporting point profile steel, a steel stranded wire and a matching anchorage device, the truss piece, the bridge deck transverse distribution beam, the bridge deck steel plate, the inclined struts and the transverse ties form a main part of a whole steel truss structure, and a steel pipe handrail is fixedly mounted on the bridge deck steel plate. The prestressed steel truss bridge is simple and easy in mounting and setting-up construction operation and convenient for modularization. Prepressing stress is applied on a tensioned truss rod member by tensioning the steel stranded wire at the bottom of a steel truss, loaded deformation of the structure can be reduced, residual deformation after unloading is eliminated, the structure is helped in elastic recovery, and the objectives of improving crossing capability, load-bearing capability and safety coefficient are achieved.
