CASSETTE-VIBRATION ISOLATION DEVICE

摘要

Provided is a cassette-vibration isolation device that is easy to upkeep (maintain) and that can cause a heavy structure to rise during an earthquake. The device is provided with an upper base and a lower base that are arranged so that the bottom surface of the upper base faces the upper surface of the lower base; a cavity, which is formed between the upper base and the lower base, and the inside of which is filled with fluid; sealing members, which are provided in an attachable/detachable manner along the inner walls of the cavity, and which maintain the state wherein the cavity is filled with fluid; and a valve, which connects the cavity and a fluid-supply source, and which supplies fluid to the inside of the cavity. During an earthquake, the upper base can rise from the lower base due to the supply of fluid via the valve to the inside of the cavity.
