Hollow slab bridge structure enhancing transverse rigidity
The invention provides a hollow slab bridge structure enhancing transverse rigidity, and belongs to the technical field of bridge engineering. According to the technical method, a transverse bridge direction pre-stress rib pipeline is reserved on a bottom plate of each prefabricated plate. Full hinge joints are arranged between the prefabricated plates, and in other words, the height of the hinge joints is equal to that of the prefabricated plates. Meanwhile, the structure of the full hinge joints makes the interval between the bottoms of the prefabricated plates become larger, so that transverse pre-stress ribs are constructed smoothly. In addition, flat anchorage devices are adopted for the transverse pre-stress ribs, and the requirement for the thickness of the bottom plates of the prefabricated plates can be effectively lowered. By the application of the design method, compared with common hinge joints, the resistance to shearing of the hinge joints is better. In cooperation with the transverse pre-stress ribs, transverse linkage of a hollow slab bridge is further enhanced; meanwhile, the transverse pre-stress ribs can effectively balance transverse bending moment.
