Description

Technical Field

[0002] With the development of economy and the continuous construction of infrastructure, bridge traffic has been continuously developed. At present, in bridges, bearings are important components connecting the superstructure and the substructure, which can reliably transmit the reaction force and deformation, displacement and rotation angle of the superstructure of the bridge to the substructure.

[0003] The wire rope cable support is a common basin-type and spherical support with a wire rope structure added. Its function is that when the support encounters an earthquake, the cable plays a role of buffering, protection and limiting, preventing the upper beam structure from being displaced too much, and preventing the beam from falling. At present, in order to install the wire rope cable structure on the structure of the ordinary support, the upper and lower structures of the wire rope support are first made very thick (for grooving) and the upper and lower sealing plates are added, thereby increasing the overall height, resulting in a heavier support weight, and it is not convenient and fast when maintenance and replacement are required.
