An interlayer noise prevention structure of a building is provided to reduce the spread of interlayer noise and to keep the indoor space of a multistoried building quietly by preventing the transfer of noise to the lower floor along a wall if vibration occurs on the bottom of the upper floor and the wall. An interlayer noise prevention structure of a building is completed by installing dampers(100,100') on a wall(400) between the bottom of the upper floor and the lower floor to absorb the vibration occurring on the bottom of the upper floor and the wall of the upper floor, putting support skeletons(500) on the dampers to absorb floor impact directly, inserting an elastic pad(160) to the contact part of a support frame and a column(200) to prevent the transfer of the vibration occurring on the support frame and installing a cover(300) to the appointed part of the wall to cover up the damper. The damper contains a main body formed on the top of a wall horizontally in the shape of a long bar, a support frame put on the main body, and a piston placed between the support frame and the main body to support the support frame. |
