Three-dimensional vibration isolation support

Abstract

The invention discloses a three-dimensional vibration isolation support. The three-dimensional vibration isolation support comprises an upper connecting plate, a lower connecting plate and a sliding block assembly, and the upper connecting plate is used for being connected with an upper structure; the lower connecting plate is used for being connected with a lower structure, the lower connecting plate is located below the upper connecting plate, and the lower connecting plate and the upper connecting plate are oppositely arranged in a spaced mode and can horizontally move relative to each other; the sliding block assembly is arranged between the upper connecting plate and the lower connecting plate, the vertical bearing capacity of the sliding block assembly is large, and the vertical rigidity of the sliding block assembly is small, so that the vertical natural vibration period of the three-dimensional vibration isolation support is small, and the three-dimensional vibration isolationsupport is used for vertical vibration isolation; and the sliding block assembly can slide between the upper connecting plate and the lower connecting plate, so that the horizontal rigidity of the three-dimensional vibration isolation support is small, and the three-dimensional vibration isolation support is used for horizontal vibration isolation. According to the three-dimensional vibration isolation support, vibration isolation in the horizontal direction and the vertical direction can be achieved at the same time, the upper structure is prevented from being damaged in an earthquake, meanwhile, the use comfort of a building in vertical vibration is guaranteed, the vibration isolation performance is good, design is simple, the service life is long, the structure is simple, and arrangement is convenient.

Description

technical field [0001] The invention relates to the technical field of civil engineering structures, in particular to a three-dimensional vibration isolation support. Background technique [0002] Currently commonly used vibration isolation bearings such as laminated rubber vibration isolation bearings, etc., the natural vibration period of the vibration isolation bearing is related to the upper mass, so the vibration isolation performance will change with the quality of the upper structure, which is not conducive to design and long-term use; at the same time The vertical vibration of the ground caused by subway vibration will affect the comfort of the building, and the current isolation bearings lack the ability to isolate the vertical vibration of the environment. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, an object of the present invention is to propose a kind...
