PURPOSE: An interlayer noise prevention device is provided to prevent the interlayer noise by guiding to and dispersing in an indoor air layer. CONSTITUTION: An interlayer noise prevention device comprises a noise inducement heat insulation board(10), a noise protector(20), a autoclaved lightweight concrete(30), a finishing mortar layer(40), and a floor finishing member(50). The noise guiding insulating plate adheres closely to the corner of a floor slab(1) meeting with a wall(2). The noise guiding insulating plate has a noise passage(15). The noise passage penetrates toward the upper end of a side plate from the one side of a floor plate via the inside of the floor plate. The noise protector is laminated on the upper side of the bottom slab in multi-stages. The autoclaved lightweight concrete is placed on the top of the noise protector. The finishing mortar layer is manufactured with a heating pipe(41) buried in the top of the autoclaved lightweight concrete. The finishing member is installed on the top of the finishing mortar layer. |
