Abstract

The invention discloses a three-dimension shock isolation system, the vertical shock isolation bracket structure is: an orienting component is arranged on the parallel shock isolation bracket, a convex shaft is arranged in the orienting component, there has resistance material between the convex shaft and the orienting component, a cover board fixed with the orienting component is arranged on the resistance material, the upper end of the convex extrudes out the orienting component, the lower end matches with the orienting component movably, there has gap between the lower end and the orienting component, a upper connection board is arranged on the disk spring overlapped component, which is fixed with the convex shaft, and matches with the outer surface of the orienting component movably, there has gap between it and the upper end. The overlapping quantity of the disk spring component is at least two, which is covered out of the outer surface of the orienting component, and matches with the orienting component movably. The system can restrain the transmitting of vertical and parallel earthquake wave to the buildings, easy to be adjusted, the lifespan is long, and the performance is stable.

Description

technical field [0001] The invention relates to a vibration isolation support. Background technique [0002] Seismic isolation of the building foundation is to set a flexible seismic isolation layer with sufficient reliability between the building and the foundation to control the transmission of seismic waves to the upper structure. Theoretical and experimental research and engineering practice show that base isolation technology is one of the most effective methods for buildings to resist earthquake disasters. At present, the seismic isolation research of the horizontal seismic component has achieved gratifying results in various countries in the world, and has been widely used in engineering practice. However, since the ground motion during an earthquake is a spatial motion, in addition to horizontal seismic waves, vertical seismic waves are equally destructive. Especially for some high-intensity areas and areas near the epicenter, the vertical seismic component is very...
