The application relates to an assembled hollow slab girder, which belongs to the technical field of bridges. It includes a slab girder body. The slab girder body includes a hollow slab girder and a cantilever. The cantilever is located on both sides of the hollow slab girder and integrally formed with the hollow slab girder. The cantilever is located near the bottom of the hollow slab girder. An upward slope hole is embedded in the hollow slab beam. The top of the upward slope hole is located on the top surface of the hollow slab beam, and the bottom end is located on the side of the hollow slab beam. A downward slope hole is reserved on the cantilever , the top of the downward slope hole is located on the top surface of the cantilever, and the bottom end is located on the bottom surface of the cantilever. After assembly, the upper inclined hole and the lower inclined hole of the adjacent hollow plate girder are coaxial, the upper inclined hole is embedded with the upper inclined pipe, and the lower inclined hole is embedded with the lower inclined pipe, and the upper inclined pipe and the lower inclined pipe are connected by internal threads There is the same connecting rod. The application has the effect of improving the transverse connection strength between assembled plate girders.
Description
technical field [0001] The present application relates to the technical field of bridges, in particular to an assembled hollow plate girder. Background technique [0002] The prefabricated hollow slab girder has the advantages of simple structure, convenient construction, small building height, easy to make inclined bridges and curved bridges, standardized design, factory-like mechanized construction, and small hoisting weight. It is widely used in small and medium-span bridges. In recent years, a large number of prefabricated concrete slab girders have been built in my country, and bridges with a span of less than 20m basically adopt this type of structure. At present, the horizontal connection between the slab girders of the prefabricated hollow slab girder bridge is mainly realized by post-cast concrete hinge joints. The boards work together to avoid the unfavorable stress phenomenon of the single board. [0003] At present, the existing Chinese patent with the notifica...
