Abstract

The invention discloses a bidirectional sliding basin-type shock absorbing bearing for bridges, which aims at providing a bidirectional sliding basin-type shock absorbing bearing for bridges with goodseismic performance. The bidirectional sliding basin-type shock absorbing bearing comprises a bottom plate provided with a steel basin ring at the upper end, a rubber plate placed in the steel basinring, placed in the steel basin ring, a support steel plate located at the upper end of the rubber plate, a sealing copper ring arranged at the outer edge of the upper end of the rubber plate and in contact with the lower end of the support steel plate, a tetrafluoro plate arranged at the upper end of the support steel plate, and a cover plate provided with mirror stainless steel plate and the mirror stainless steel plate in contact with the tetrafluoro plate at the lower end; The outer edge of the bottom plate and the outer edge of the cover plate are larger than the outer diameter of the steel basin ring; The damping ring comprises a damping ring member which is arranged on the steel basin ring and concentric with the steel basin ring. The damping ring member comprises at least two damping glue layers, a skeleton ring connecting adjacent damping glue layers, and two connecting rings respectively positioned on the damping glue layers at both ends; The damping ring member is an integral part, and the connecting rings at the two ends of the damping ring are fixedly connected with the bottom plate and the cover plate respectively.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a two-way sliding basin type damping support for bridges. Background technique [0002] A bridge is generally composed of a superstructure, a substructure, a support and ancillary structures. The superstructure is also called a bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations. The bridge bearing is an important structural component connecting the superstructure and substructure of the bridge. It is located between the bridge and the pad stone. It can reliably transmit the load and deformation (displacement and angular rotation) of the superstructure of the bridge to the substructure of the bridge. An important force transmission device of the bridge. There are two types of bridge bearings: fixed bearings and movable bearings, and movable bearings include one-way sliding bearings and t...
