Description

Technical Field

[0001] The utility model relates to a novel vibration double-control rubber bearing, belonging to the technical field of earthquake isolation of building engineering. Background Art

[0002] Rubber isolation technology has become mature. Theory, experiment and earthquake detection have shown that isolation technology is the most effective measure for passive defense against earthquake disasters. It has played a huge role in all previous earthquakes. The isolation bearing isolates a large amount of horizontal earthquake energy and guarantees the safety of people's lives and property to the greatest extent. In recent years, with the rapid development of rail transit network construction, the comfort problems of a large number of buildings near subways and subway-covered buildings have become increasingly prominent. For example, the noise of New York subway stations has reached 115 decibels, which seriously affects human health; the noise and vibration generated by the subway when passing under the Bastille Opera House seriously affect the quality of opera performances, and the vibration noise of the subway seriously affects the quality of life of residents. In addition, some high-precision equipment processing and equipment operation also have high requirements for vibration control. For example, the work of the lithography machine needs to be isolated from vibration to meet the precision requirements; the yield of crystal cultivation is controlled by the micro-vibration of the process environment; the underground missile well group needs to control the vibration of nuclear explosion impact; the operating environment of the super telescope needs to strictly control the micro-vibration of the space, etc.

[0003] At present, seismic isolation technology can ensure the safety of buildings and people's lives and property when buildings encounter earthquake disasters, but it is difficult to control environmental vibrations under normal use. When people have higher requirements for quality of life and special process requirements, traditional rubber seismic isolation technology is difficult to achieve the ideal control target. The problem of reducing vibration damage to buildings adjacent to subways and buildings above subways and secondary noise pollution in buildings in high-intensity areas is becoming increasingly prominent and has received widespread attention.
