Self-resetting type grinding disc vibration isolation pier device

Abstract

The invention provides a self-resetting type grinding disc vibration isolation pier device. The device comprises an upper pier and a lower pier, wherein the upper pier and the lower pier are arrangedup and down, the bottom end of the upper pier is provided with an upper storage bin, the top end of the lower pier is provided with a lower storage bin, the bottom surface of the upper pier is contacted with the top surface of the lower pier, the upper storage bin is communicated with the lower storage bin to form a storage bin, grinding materials are filled in the storage bin, the center of the storage bin is provided with a deformation memory elastic element, and the upper end and the lower end of the deformation memory elastic element are respectively connected with the upper pier and the lower pier; and an upper groove belt is arranged on the bottom surface of the upper pier, one end of a plurality of grooves of the upper groove belt is communicated with the storage bin, the other endof the plurality of grooves of the upper groove belt extends outwards to the edge of the upper pier, the top surface of the lower pier is provided with a lower groove belt, one end of the plurality ofgrooves of the lower groove belt is communicated with the storage bin, and the other end of the plurality of grooves of the lower groove belt extends outwards to the edge of the lower pier. The self-resetting type grinding disc vibration isolation pier device has low cost, simple and convenient construction and recoverable function, and further dissipates the seismic energy through the grinding effect while realizing the reduction of the overall vibration reaction of the upper structure based on the sliding vibration isolation technology.

Description

technical field [0001] The invention relates to the field of seismic isolation technology, in particular to a self-resetting type grinding disc seismic isolation pier device. Background technique [0002] Earthquake is a sudden natural disaster with great harm. In an earthquake, the seismic action on buildings is gradually amplified from bottom to top, which will cause damage to structural components, and even lead to the collapse of buildings and the resulting casualties. casualties. In order to prevent the collapse of buildings when an earthquake occurs, at present, some important buildings and complex buildings use seismic isolation devices in specific parts to form seismic isolation buildings, so that the building structure can change from violent swings to slow translational motions under the action of earthquakes. The main structure above the shock-isolation device is basically in an elastic working state. That is, by changing the natural vibration characteristics of...

AI Technical Summary

Problems solved by technology

[0003] In actual earthquakes, buildings in villages and towns with a large number of areas are often the most severely damaged and pose the greatest threat to life and property safety. However, there are two main types of seismic isolation systems that are most common in engineering at present. The first is It is to introduce a seismic isolation layer with low lateral stiffness between the structure and the foundation; the second is to introduce a sliding device at the bottom of the foundation or structure. There are still some deficiencies in terms of seismic energy or self-resetting function
