PURPOSE: A seismic isolation structure of an access floor is provided to stably keep the original condition of an access floor by effectively absorbing the powerful shock due to earthquake. CONSTITUTION: A seismic isolation structure of an access floor(100) comprises an earthquake-proof cover(250), a bearing(320), and a lower reinforcement material. The earthquake-proof cover is formed on the end(210) of a floor panel(200). An elastic body(260) like a sponge, a rubber, or a spring is embedded in the earthquake-proof cover. The bearing is formed of an elastic body. The bearing is mounted on the lower end of a support bar(300) to reduce the vertical vibration. The lower reinforcement material bears the horizontal vibration by connecting lower parts of the support bars in an X-shape. |
