Vibration isolation device with self-resetting function and assembling method thereof

Abstract

The invention discloses a vibration isolation device with a self-resetting function and an assembling method thereof. A circular table plate is connected with an upper structure, and a load conversion energy consumption assembly is connected with a foundation; when a horizontal load is applied, the circular table plate and a special-shaped vibration reduction support are rubbed to dissipate energy, and meanwhile, low-yield-point steel and rubber in the special-shaped vibration reduction support deform to dissipate the energy; when a vertical load is applied, except for the energy consumption, high-strength bolts consume the energy through friction; when a downward load is applied, an arc-shaped plate transmits force to an SMA spring through mechanical rotation, and the SMA spring is pulled to consume the energy; when an upward load is applied, the circular table plate transmits the load to a bearing plate through a steel cable, and the arc-shaped plate transmits the force to an anti-vibration pad through mechanical rotation. According to the vibration isolation device with the self-resetting function and the assembling method thereof, the advantages of good tensile property and self-resetting capacity of SMA and the advantages of stable energy consumption, good ductility and the like of the low-yield-point steel are fully utilized, vibration isolation is achieved in combination with a mechanical principle, and meanwhile the advantages of recoverability, high assembly degree and the like are achieved.

Description

technical field [0001] The invention relates to the technical field of building vibration isolation devices, in particular to a vibration isolation device with a self-resetting function and an assembly method thereof. Background technique [0002] In order to better attract talents and invigorate the economy, some emerging first-tier cities have begun to build large-scale construction projects, and vigorously build subways, high-speed rail and other facilities. However, while rail vehicles such as trains, subways, and high-speed rails bring great convenience to people’s daily travel, they also generate large vibrations, which bring great troubles to residents living near rail lines. In some remote places where vehicles are difficult to reach, it is difficult for a vibration isolation device that is too large to be transported by manpower to play its role. It can be seen that it is necessary to seek a vibration isolation device that is easy to install, dismantle and transport...

Problems solved by technology

In some remote places where vehicles are difficult to reach, it is difficult for a vibration isolation device that is too large to be transported by manpower to play its role. It can be seen that it is necessary to seek a vibration isolation device that is easy to install, dismantle and transport, and most vibration isolation devices The vibration device has no self-resetting function

[0003] The invention patent application with the publication number CN112324219A discloses "a combined vibration isolation device with self-resetting function and anti-torsion". The device uses multiple springs in series to perform self-resetting movement. Provides restoring force in the vertical direction
