Three-dimensional shock insulation support

Abstract

The invention provides a three-dimensional shock insulation support. The three-dimensional shock insulation support comprises an upper support plate, a lower support plate and multiple support bodieslocated between the upper support plate and the lower support plate, a round cavity is formed in the middle of the lower support plate, a disc is concentrically arranged in the cavity, a round hole isformed in the middle of the upper side wall of the cavity, and a fixed column is arranged in the round hole and fixed to the middle of the disc. Each support body comprises an upper fixed plate, a first friction plate, a second friction plate, a rubber support and a lower fixed plate, all of which are sequentially arranged from top to bottom, the lower side face of each first friction plate is ina concave spherical shape, the upper side face of each second friction plate is in a convex spherical shape cooperating with the lower side face of the corresponding first friction plate, a limitingring and limiting barrels are further fixed to the lower side face of the upper support plate, and the lower ends of the limiting barrels are lower than the upper ends of the lower fixed plates. An elastic steel plate set is arranged between the fixed column and each limiting barrel. Due to the adoption of the technical scheme, the shock insulation effect of the three-dimensional shock insulationsupport is good; the resetting capability is good; and the rubber supports are not prone to being destroyed.

Description

Technical field[0001]The invention belongs to the technical field of construction engineering, and specifically is a three-dimensional seismic isolation support.Background technique[0002]Seismic action is a common load in structural engineering, and the load is the main factor leading to structural damage and structural collapse. The use of effective protective measures for the structure to avoid damage to the structure under the action of an earthquake is not only related to the seismic performance of the structure itself, but also directly affects the lives of the people and the safety of the national economy and property, which has broad development prospects and economic benefits.[0003]The traditional vibration isolation support is a rubber vibration isolation support, which includes a rubber support fixed between an upper seat plate and a lower seat plate. Although the rubber bearing in the traditional seismic isolation bearing has strong compressive performance, its tensile an...

AI Technical Summary

Problems solved by technology

Although the rubber bearing in the traditional seismic isolation bearing has strong compressive performance, its tensile performance and torsion resistance are poor, and it is easy to be damaged when an earthquake occurs; and the traditional seismic isolation bearing completely relies on the rubber bearing Its own deformation is used to buffer the earthquake force, the isolation effect needs to be improved, and the reset ability is poor
