Problems solved by technology
However, the substructure of the bridge is still dominated by concrete piers, so it is inevitable that concrete piers and steel box girders will be consolidated during the engineering process. However, the technology for consolidating bridge piers and steel box girders of different materials is not yet mature.

The invention discloses a concrete cylinder pier and girder fixed-connection structure. The fixed-connection structure comprises a bridge pier and a steel box girder. The bridge pier comprises a cylinder structure formed by pouring concrete. A steel plate hoop is added to the cylinder structure and connected with a bottom plate of the steel box girder. A shear nail is arranged in the steel plate hoop, and the steel plate hoop and the cylinder structure are connected together through the shear nail. Meanwhile, reinforcing ribs are added, and the steel plate hoop and the steel box girder are connected through the reinforcing ribs. The bridge pier and the bottom plate of the steel box girder are fixedly connected more reliably through the reinforcing ribs, and the whole fixed-connection structure is reliable in connection, simple in structure and convenient to construct.
Description
technical field [0001] The invention relates to the technical field of steel structure bridge construction, in particular to a consolidated connection structure between a concrete cylindrical pier and a steel beam. Background technique [0002] Bridges refer to buildings erected on rivers, lakes and seas to enable vehicles and pedestrians to pass smoothly. Bridges are generally composed of superstructures, substructures, supports and auxiliary structures. Structure; the substructure includes abutment, pier and foundation; the support is the force transmission device set at the supporting place between the bridge span structure and the pier or abutment; the auxiliary structure refers to the bridge head buttress, conical slope revetment, revetment, and diversion works Wait. The pier is located in the middle of the bridge and supports the superstructure of two adjacent spans. Its function is to transfer the load from the superstructure to the foundation reliably and effectivel...
