A vibration isolation device with self-resetting function and its assembly method

Abstract

The invention discloses a vibration isolation device with a self-resetting function and an assembly method thereof. The circular platform is connected with the upper structure, and the load conversion energy-dissipating component is connected with the foundation; At the same time, the low-yield point steel and rubber deformation energy consumption in the special-shaped vibration-absorbing bearing; when subjected to vertical load, in addition to the above-mentioned energy consumption, high-strength bolt friction energy consumption; The force is transmitted to the SMA spring, and the SMA spring is tensioned to dissipate energy; when subjected to an upward load, the round table plate transmits the load to the bearing plate through the steel cable, and the arc plate transmits the force to the vibration damping pad through mechanical rotation. The invention makes full use of the advantages of SMA's good tensile performance, self-resetting ability, low yield point steel, stable energy consumption, and good ductility, and combines mechanical principles to realize vibration isolation, and has the advantages of recoverability and high assembly degree.

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
