AI Technical Summary

Technical Problem

The existing beam connecting devices cannot effectively control bridge damage caused by the lifting of the support. Especially when earthquakes and other disasters occur, the traditional devices have poor torsional resistance and high maintenance costs, making it difficult to meet the needs of multi-directional tensile resistance and functional diversity.

Method used

A multi-functional vertical beam connecting device based on chain-type energy-consuming members is adopted. The device includes energy-consuming members, chain structure, pier connection assembly, beam connection assembly and pre-embedded components. Through the ring-ring connection form of the chain structure, the high damping characteristics and self-reset characteristics of the energy-consuming members are used to realize multi-directional tensile and limiting functions.

Benefits of technology

It improves the stability and safety of the overall structure of the bridge, reduces the losses caused by disasters, and improves the flexibility and maintenance efficiency of the device, suitable for all types of bridges.
