Replaceable modularized comb-like seismic mitigation and isolation bearing and preparation method thereof

Abstract

The invention discloses a replaceable modularized comb-like seismic mitigation and isolation bearing and a preparation method thereof, which belong to the technical field of bridge bearing. The replaceable modularized comb-like seismic mitigation and isolation bearing is mainly characterized by comprising a bearing main body, wherein an upper bearing plate and a lower bearing plate are arranged on the bearing main body; a seismic reduction and energy consumption module, which is formed by a seismic reduction and energy consumption base and a seismic reduction and energy consumption plate, is arranged on the surrounding of the upper bearing plate; the seismic reduction and energy consumption base is connected with the upper bearing plate through a first bolt; a seismic reduction and energy consumption module baffle matched with the seismic reduction and energy consumption module is arranged on the surrounding of the lower bearing plate; the seismic reduction and energy consumption module baffle is connected with the lower bearing plate through a second bolt; and a trapezoidal comb whose tooth form is matched with the shape of the seismic reduction and energy consumption plate is arranged on the seismic reduction and energy consumption module baffle. The replaceable modularized comb-like seismic mitigation and isolation bearing disclosed by the invention is advantaged that fragile parts and energy consumption parts are modularized in case of an earthquake, the seismic mitigation and isolation bearing is conveniently and rapidly replaced, the cost needed to repair the bearing is reduced, and manpower, material and financial resources of the replaceable modularized comb-like seismic mitigation and isolation bearing are saved when being compared with a support which needs to be integrally replaced.

Description

technical field [0001] The invention belongs to the technical field of bridge supports, in particular to a replaceable modular comb-teeth type shock-absorbing and isolating support and a preparation method thereof. Background technique [0002] The bridge support is an important structural component connecting the upper structure and the lower structure of the bridge. Its importance cannot be ignored because the cost only accounts for a small proportion of the entire bridge. It should be selected according to the characteristics of the designed bridge and the geographical location of the bridge. Supports that meet the requirements, especially in areas with high seismic intensity, are very important to choose a suitable support. Not only should the performance in normal use be considered, but also the difficulty of repairing the support when an earthquake occurs. The construction of a project should not only consider the cost of construction, but also consider the difficulty ...

AI Technical Summary

Problems solved by technology

The existing shock-absorbing and isolating bearings have the following defects: first, when the earthquake occurs, the shear pins or bolts used to connect the limit baffle and the upper seat plate are not easy to replace after being cut; second, when the earthquake occurs, the energy consumption is zero. The parts are deformed, not easy to remove, not easy to replace
