Problems solved by technology

The friction pendulum bearing can consume part of the lateral vibration, but the horizontal stiffness is too low, which will reduce its vibration damping effect for weak foundation or soft pier
Therefore, it cannot meet the use in complex environments
[0004] And because the existing bridge construction needs to be carried out without affecting the normal walking of the roadway, the suspension of the roadway can only last for a short period of time, so the construction of the roadway has also put forward higher requirements

Abstract

The invention discloses an anti-seismic bridge support comprising a base and an upper formwork table arranged on the surface of the base. A central support column is arranged in the middle of the base, the base surface at the periphery of the central support column is arranged as a conical surface, and an auxiliary limiting cavity is formed in the middle, corresponding to the central support column, of the upper formwork table. The auxiliary limiting cavity is arranged on the center support column in a covering mode, a positioning groove is formed in the middle of the central support column, and a guide column is arranged in the positioning groove. A strong spring is arranged between the guide column and the upper formwork table, a plurality of first shock-absorption dampers are arranged on the surface of the formwork table and penetrate through the upper formwork table to abut against the conical surface, and the first shock-absorption dampers are perpendicularly arranged on the surface of the conical surface. A side skirt edge is further arranged on the periphery of the upper formwork table, and a plurality of second shock-absorption dampers are uniformly arranged between the side skirt edge and the side edge of the base. An overhead space is formed between the conical surface and a profiling surface. The anti-seismic bridge support can dissipate transverse and vertical vibration to achieve the anti-seismic effect, and can further assist a bridge to rotate.

Description

technical field [0001] The invention relates to the field of bridges, in particular to an anti-seismic bridge support. Background technique [0002] In bridge engineering, prefabricated buildings, and steel structure buildings, bearings are widely used. The main function of bearings is to resist earthquakes and reduce impact. [0003] The traditional lead rubber bearing has an obvious effect on eliminating vertical vibration, but its effect on energy dissipation of vibration in the horizontal direction is limited. The friction pendulum bearing can consume part of the lateral vibration, but the horizontal stiffness is too low, which will reduce its vibration damping effect for weak foundation or soft pier. Therefore, the use in complex environments cannot be satisfied. [0004] And because existing bridges need to be constructed under the condition of not affecting the normal walking of the sidewalk, the suspension of the sidewalk can only last for a short time, so higher r...
