The invention discloses a steel-concrete composite box girder viaduct structure, which belongs to the technical field of building bridges, and comprises a main girder, which is sequentially assembled from several segmental box girders, and the segmental box girders include concrete box girders The main body and the steel structure connection plate, the steel structure connection plate straddles the bar-shaped notch and its two sides pass through the first elastic shear force connection member and the second elastic shear force connection member respectively and the two inner edge plates of the concrete box girder main body Connection, the steel structure connection plates of two adjacent sections of the box girder are connected by fasteners, and a slip buffer device is also arranged between the steel structure connection plate and the inner wall of the concrete box girder main body. The device of the present invention connects the steel beam and the concrete flange plate by means of elastic compression, and replaces the hard connection through friction and elastic buffering, thereby solving the technical problem of easy loosening caused by the hard connection. Improve the safety performance of the bridge.
Description
technical field [0001] The invention belongs to the technical field of building bridges, in particular to a steel-concrete composite box girder viaduct structure. Background technique [0002] In recent years, steel-concrete composite beams have been more and more widely used in urban overpass bridges and building structures in my country, and are developing in the direction of large spans. The application practice of steel-concrete composite beam in our country shows that it has both the advantages of steel structure and concrete structure, has significant technical, economic and social benefits, is suitable for the national conditions of my country's basic construction, and is one of the main development directions of the future structural system . Steel-concrete composite beam is a new type of structure developed on the basis of steel structure and concrete structure. It mainly resists the lifting and relative slippage at the interface between the steel beam and the conc...
