AI Technical Summary

Technical Problem

The flat plate connectors of existing steel bridges are prone to deformation and breakage under pressure, and the fasteners are susceptible to erosion by rainwater, affecting the connection effect and service life.

Method used

Design a connecting device for steel frame bridges, comprising an internal reinforcing component and a protective component. The internal reinforcing component increases compressive strength through a welded quenched steel frame and support rods, while the external protective component protects fasteners with a protective cover and rubber rings to prevent rainwater erosion.

Benefits of technology

It improves the compressive strength and connection stability of flat plate connectors, extends service life, protects fasteners from external corrosion, and maintains stable connection performance.
