Abstract

The invention relates to a steel beam and composite beam connecting structure. The connecting structure comprises a steel box girder and a composite girder which are connected. The steel box girder comprises a steel box girder main longitudinal beam and steel box girder cantilever slabs connected to the two sides of the steel box girder main longitudinal beam. The steel box girder main longitudinal beam comprises a steel girder top plate, a steel girder bottom plate and a steel girder web. The steel beam top plate and the steel beam bottom plate are connected to upper and lower ends of the steel beam web. The composite girder comprises a composite girder main longitudinal beam and composite girder cantilever slabs connected to the two sides of the composite girder main longitudinal beam. The composite girder main longitudinal beam comprises a composite beam steel top plate, a composite girder steel bottom plate and a composite girder steel web. The composite girder steel top plate andthe composite girder steel bottom plate are respectively connected to the upper end and the lower end of the composite girder steel web, the steel beam web is welded with the composite beam steel web,the composite beam concrete is filled above the composite girder steel top plate, and the composite beam concrete is filled on the composite girder steel bottom plate. The connecting structure has the advantages of being simple in form, smooth in force transmission, convenient to connect and beneficial to standardized manufacturing and modular assembly of the hybrid beam of the cable-stayed bridge.

Description

technical field [0001] The invention belongs to the technical field of bridges, in particular to a connection structure of steel beams and composite beams. Background technique [0002] Steel girder bridges are the common structure of cable-stayed bridges. The steel has high rigidity and light weight, but the cost is high. Therefore, the use of steel-concrete composite girders can maximize the advantages of two different materials. [0003] Chinese patent CN110863417A discloses a steel-concrete composite girder bridge with rapid installation and its construction method. Between the bridge decks, through steel bars are penetrated into the circular lapped steel bars, the vertical and horizontal wet joints are poured with high-performance concrete, and the bottom plates of the longitudinally adjacent steel girders are connected by spliced ​​steel plates and high-strength bolts. The construction method mainly includes: prefabricated steel-concrete composite beams, hoisting in p...
