Description
Technical field
The present invention relates to subtract technical field of isolation, especially a kind of earthquake isolating equipment accessory anti-vibration protected for historical relic.
Background technology
Nearly 4700 of museum of China at present, most museums are on earthquake zone.The country-level museum in 96, continent
In, 90 or more are located at earthquake territory, wherein 69 are located at 7 degree or more high intensity Zones, earthquake disaster causes many preciousnesses
Historical relic damages.To improve the anti-vibration protected present situation of Cultural relics in museum, museum of China largely used isolation measure in recent years, to subtract
Its light dither effect in earthquake, reaches and exempts from destroyed purpose.
The working method of earthquake isolating equipment is that showcase or historical relic are separated with construction floor, and showcase is made under geological process and is built
