Description

Technical Field

[0002] Bridge bearings are important structural components that connect the superstructure and substructure of a bridge. Located between the bridge and the bearing pad, they reliably transfer the loads and deformations borne by the superstructure to the substructure, making them a crucial force transmission device for bridges.

[0003] Existing bridge bearings, such as the one disclosed in patent CN219364304U, use buffer rubber pads and vertical spring tension shafts to limit the position of the upper and lower components of the device when the bridge shakes as a whole, so as to prevent the components from being misaligned due to the shaking of the bridge and ensure the buffering effect of the device; however, they mainly focus on vertical tensile and seismic resistance, and the seismic resistance effect in the lateral direction is poor, which makes the bearing easy to be damaged.
