Problems solved by technology

Under the action of near-fault earthquakes, the base isolation structure will have a large displacement, resulting in roll instability of the structure or damage to the support. Therefore, it is necessary to add a limit protection device to the isolation layer.
Most of the existing limit devices of the shock-isolation layer are fixed limit devices with non-adjustable positions in one direction. The present invention provides a spring limit device with simple structure, convenient use and installation, and flexible adjustment of the force contact position according to the actual situation. bit device

Abstract

The invention provides a multi-directional adjustable spring limit device comprising a lower foundation fixed seat body and an upper movable seat. When an isolation layer of a building foundation produces large displacement resulting in structural roll instability or seat damage, the isolation layer needs to be provided with a limit protection device. According to the limit device for the buildingisolation layer, a limit spring can be flexibly adjusted according to the vertical, left-right and front-back directions to reset the isolation layer timely, and the limit effect of the isolation layer is greatly improved.

Description

technical field [0001] The invention relates to a spring limiting device for a building shock-isolation layer, which belongs to the field of earthquake-isolation technology of civil engineering disaster prevention and reduction engineering. technical background [0002] Earthquakes, wind vibrations or other equipment vibrations in nature will affect the vibration of the building itself, and in severe cases, it will cause large irreversible damage to the building, endangering people's lives and property. With the development of technology, engineers found that seismic isolation technology can effectively reduce the damage caused by vibration to buildings. At present, seismic isolation technology is often used in bridge structures, grid structures and building structures in the construction field. Seismic isolation technology prolongs the basic natural vibration period of the structure by setting a flexible seismic isolation layer in the structure to avoid the excellent perio...
