Shock-isolating device for foundation of high-rise building

Abstract

The invention belongs to the technical field of shock-isolating devices and particularly relates to a shock-isolating device for a foundation of a high-rise building. The shock-isolating device for the foundation of the high-rise building aims to solve the technical problem that the stretching recovery capacity of a shock-isolating device is continuously lowered. According to the technical scheme, the shock-isolating device for the foundation of the high-rise building comprises a building base, an installation seat and the foundation, wherein the building base, the installation seat and the foundation are sequentially arranged from top to bottom and are sequentially connected, the two sides of the top of the foundation are provided with telescopic supporting columns, two fixing plates are welded to the top and the bottom of each telescopic supporting column and are connected through a spiral compression spring, and the outer walls of the telescopic supporting columns are sleeved with the spiral compression springs. According to the shock-isolating device for the foundation of the high-rise building, a bulb and rolling beads are in rolling friction, the wear of the bulb and the inner wall of a sliding groove is reduced, the service lives of the bulb and the sliding groove are prolonged, buffering devices can apply action force on the bulb, the bulb is prevented from sliding for a long distance, metal parts are greatly prevented from being rusted, and the stability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of shock-isolation devices, in particular to a shock-isolation device for foundations of high-rise buildings. Background technique [0002] Earthquakes have brought too much disaster and suffering to human beings. However, the earthquake itself does not cause much harm to human beings. Earthquake disasters are mainly manifested in the secondary damage caused by the collapse of buildings in the disaster-stricken area, which brings great losses to people's lives and property. With the maturity of architectural theory, disaster prevention and mitigation has become an eternal topic. [0003] For this reason, the Chinese Patent Authorization Announcement No. CN202899302U proposes "Seismic Isolation Bearings for High-Rise Buildings". In view of the flammability of the seismic bearing, a protective device is installed on the outside of the friction pendulum seismic isolation bearing, but the friction pendulum sei...

[0003] For this reason, the Chinese Patent Authorization Announcement No. CN202899302U proposes "Seismic Isolation Bearings for High-Rise Buildings". In view of the flammability of the seismic bearing, a protective device is installed on the outside of the friction pendulum seismic isolation bearing, but the friction pendulum seismic isolation bearing is installed between the foundation and the bottom of the building, and the seismic isolation bearing is in a sealed state, so resources are wasted

[0004] In order to solve the problem of house collapse caused by earthquakes, the Chinese patent authorization announcement number CN103643749A proposed "combined high-rise building isolation bearings" to solve the insufficient tensile capacity, poor isolation effect, and wind load resistance of seismic isolation bearings in high-rise buildings. It solves the problem of weak capacity, and solves the problem of excessive displacement caused by low damping and low damping that cannot overcome the wind load. However, in this patent, "the moving lever is pressed on the top of the fixed lever to form a cross in the shape of a "cross", and the building Pressed on the upper connecting plate, so the friction between the movable lever and the fixed lever is relatively large, and the movable lever and the fixed lever are easy to wear and deform. After wear and deformation, the tensile capacity of the movable lever and the fixed lever is reduced, which reduces the shock isolation recovery performance
