<P>PROBLEM TO BE SOLVED: To provide an air vibration proof floor capable of preventing vibration from transmitting to downstairs while a floor and a concrete slab are separated and the floor is supported by air so as to cut off the vibration from upstairs. <P>SOLUTION: An air vibration proof floor includes: a concrete slab for separating stories of a building from each other; a floor installed above the concrete slab; a first seal material covering the periphery of lower sides of the concrete slab and the floor to form a first airtight space between the concrete slab and the floor; a cushioning material attached between the floor and a peripheral wall; and an air feed-in mechanism automatically feeding compressed air to the first airtight space from an air tank to maintain air quantity in the first airtight space. The floor is risen from the concrete slab to be supported by the compressed air supplied to the first airtight space. <P>COPYRIGHT: (C)2013,JPO&INPIT |
