[0002] A bridge refers to a building built for roads to cross natural or artificial obstacles. It is erected across rivers, lakes, and the sea to allow vehicles and pedestrians to pass smoothly. A bridge is generally composed of a superstructure, a substructure, and ancillary structures. The superstructure mainly refers to the span structure and support system; the substructure includes abutments, piers, and foundations; and the ancillary structures refer to the bridge head cladding, conical slope protection, bank protection, diversion projects, etc.

[0003] The commonly used method for existing anti-falling beam limit devices is to install seismic tie rods. The construction period of seismic tie rods is long, which affects the backfill of the bridge abutment. The technology is backward and drilling operations are required on the back wall of the abutment. There are great risks and hidden dangers. It is gradually being eliminated. The construction technology of traditional bridge seismic devices can no longer meet construction needs. Utility Model Content

[0010] In order to limit the buffer damping rod, as a preferred limiting device for the anti-falling beam stainless steel plate of the utility model, both ends of the M48 pin shaft are detachably connected with stoppers.

[0011] In order to enable the M48 pin to move in the through hole, as a preferred limit device for preventing the beam from falling from the stainless steel plate of the utility model, the through hole is arranged as a long strip structure.
