Prestressed ferroconcrete combined simply-supported beam bridge with preprocessed assembled fish-bellied truss frame and construction method of prestressed ferroconcrete combined simply-supported beam bridge
The invention discloses a prestressed ferroconcrete combined simply-supported beam bridge with a preprocessed assembled fish-bellied truss frame. The prestressed ferroconcrete combined simply-supported beam bridge adopts the preprocessed fish-bellied truss frame and a precast concrete bridge deck, lower chord rods of the fish-bellied truss frame adopt a steel-coated concrete structural component, prestress is tensed in the steel truss lower chord steel-coated concrete structural component, so that the bending rigidity of a beam body is greatly improved, compressive prestress of bridge deck concrete is reinforced after a bridge is finished, the spanning capacity of a simply-supported combined beam is greatly improved, air exposure of steel structural prestressed reinforcing bars is avoided, and the durability and the reliable properties of the prestressed reinforcing bars are greatly improved; besides the ferroconcrete combined simply-supported beam bridge adopting the structure can be convenient to preprocess and assemble, so that requirements of preprocessing the structural component in a factory and rapidly mounting the structural component on site can be completely met. Accordingly, the invention further discloses a corresponding construction method, and the construction method is safe, reliable, convenient and rapid.
