Integral bridge abutment and steel beam combined part structure

Abstract

The invention discloses an integral bridge abutment and steel beam combined part structure comprising a bridge abutment and a steel beam; one end of the steel beam is fixedly embedded in the bridge abutment, the steel beam is made of section steel and comprises an upper wing plate, a lower wing plate and a web plate connecting the upper wing plate and the lower wing plate, and a bearing plate connecting the upper wing plate, the lower wing plate and the web plate is arranged on the interface of the bridge abutment and the steel beam; the bearing plate is attached to the interface of the bridge abutment and the steel beam in parallel and is perpendicular to the web plate. The integral bridge abutment and steel beam combined part structure has the advantages that the local tensile stress of concrete is reduced, the stress performance of the steel-concrete joint part is enhanced, and the field construction efficiency is improved.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to a joint structure of an integral abutment and a steel girder. Background technique [0002] Integral steel-concrete composite girder bridges have obvious advantages over simply supported girder bridges in small and medium-span bridges. Combining the advantages of integral abutments and steel-concrete composite girders, the formed steel-concrete integral abutment bridges can eliminate Expansion joints and supports solve the durability problem of bridge expansion joints and supports and reduce bridge maintenance costs. They also have the advantages of light weight, high rigidity, and strong spanning ability of steel-concrete composite structures, which are convenient for factory prefabrication and assembly. style construction. [0003] The bridge junction is the key part of the integral steel-concrete composite bridge, but at present, the abutment-steel beam junction of the integ...

Problems solved by technology

[0003] The bridge junction is the key part of the integral steel-concrete composite bridge, but at present, the abutment-steel beam junction of the integral steel-concrete composite girder bridge is often equipped with welding stud connectors and perforated plate connectors, which need to be arranged in a limited space A large number of connectors, the complex structure affects the quality of concrete pouring, and the force is not clear, which is easy to reduce economic benefits
