Three-way shock insulation pedestal with spring damp guide rod device

Abstract

The invention relates to a three-way shock insulation pedestal with a spring damp guide rod device. The pedestal comprises a bottom plate, a lower disc shock insulation device, a middle disc conversion device, an upper disc shock insulation device and a top disc, wherein the lower disc shock insulation device is fixed to the bottom plate; the lower disc shock insulation device is connected with the top disc through the middle disc conversion device; the upper disc shock insulation device is connected between the bottom plate and the top disc. According to the pedestal, the purposes of horizontally insulating shock while reducing the vertical earthquake effect are achieved, the shock insulation protection is provided for a structure with vertical and horizontal shock reduction and insulation requirements, the path of transmission of the earthquake effect to protected equipment or reserved cultural relics is cut off or weakened to the maximum extent, and the earthquake input energy is reduced to protect the equipment or the reserved cultural relics.

Description

technical field [0001] The invention relates to shock-absorbing and isolating equipment, in particular to a three-way shock-isolating pedestal comprising a spring damping guide rod device. Background technique [0002] China is located in an earthquake-prone area and is one of the countries most seriously affected by earthquakes in the world. As a natural disaster, earthquakes pose a great threat to human life and property safety. With the rapid development of social economy, the losses caused by earthquakes are becoming more and more serious. Earthquakes are caused by the fact that the crustal rocks are in a complex stress state. With the continuous change of the earth's crust, when the in-situ stress exceeds the ultimate strength of a certain rock layer, the rock layer will suddenly break and dislocate, causing vibrations and elastic The waves spread to the surface, causing objects with a certain mass near the surface to generate inertial force. When the anti-seismic abil...

Problems solved by technology

However, the actual earthquake damage shows that the impact of vertical earthquakes on objects cannot be ignored, and in some cases, its effects will exceed those of horizontal earthquakes.

Traditional seismic isolation pedestals are generally used for isolation in the horizontal direction, which makes traditional seismic isolation pedestals not meet the requirements of vertical seismic isolation on the one hand, and on the other hand, in some cases, it will also amplify the vertical seismic action effect
