Camber surface sliding type three-dimension isolation bearing seat

Abstract

The invention discloses a camber surface sliding type three-dimension isolation bearing seat. The camber surface sliding type three-dimension isolation bearing seat comprises a top plate, upper sliding blocks, connecting rods, lower sliding blocks, an arc-shaped sliding rail, springs, a connecting plate, a rubber bearing seat and a bottom plate; the arc-shaped sliding rail is provided with a bottom and a top surface, the sliding tail is arranged on the top surface, and one end of the sliding rail to the other end of the sliding rail is downward in an arc shape; the upper ends and the lower ends of the connecting rods are fixedly connected with the upper sliding blocks and the lower sliding blocks correspondingly, the top ends of the upper sliding blocks are slidably supported and borne inthe bottom surface of the top plate and slide directionally, the lower ends of the lower sliding blocks are slidably supported and borne to the sliding rail on the top surface of the arc-shaped sliding rail, and the connecting surfaces adopt friction materials; the upper ends of the springs are fixedly connected to the lower sliding blocks, and the lower end of the springs are fixed connected to the connecting plates; and the bottom of the arc-shaped sliding rail is fixedly connected to the top surface of the connecting plate, the bottom surface of the connecting plate is fixedly connected with the top of the rubber bearing seat, and the connecting plate is fixedly connected with the bottom of the rubber bearing seat. According to the camber surface sliding type three-dimension isolation bearing seat, the gravity bearing problem in vertical isolation design can be solved, the structure is simple, stress wearing is clear, and the camber surface sliding type three-dimension isolation bearing seat is suitable for large-scale production and use.

Description

technical field [0001] The invention relates to the technical fields of environmental vibration, anti-seismic and shock absorption, in particular to an arc sliding three-dimensional shock-isolation bearing, which can be used for shock / vibration reduction in ordinary buildings, special structures, bridges, and mechanical equipment. Background technique [0002] Remarkable research results have been achieved in building structure base isolation technology, but most of the research at home and abroad is about horizontal isolation, and there are still great challenges in vertical isolation. [0003] At present, many scholars at home and abroad have tried to develop many three-dimensional seismic isolation devices to simultaneously isolate horizontal and vertical earthquakes. Most of them use air springs and hydraulic oil for vertical isolation and convert vertical deformation into horizontal displacement of supports. combined shock absorbers. The biggest difficulty in vertical ...

AI Technical Summary

Problems solved by technology

Many three-dimensional seismic isolation devices cannot solve this problem well. When the weight of the superstructure is large, the impact on the seismic isolation layer caused by the self-weight of the structure makes the performance of the seismic isolation device unable to fully exert and become unstable, which limits its Possibility of mass production and use
