A soundproof member for preventing interlayer noise of a building is provided to prevent the crisscross and deviation among soundproof panels by forming recessed parts and projected parts at upper, lower, front, rear, left, and right ends of the of first, second, and third soundproof panels. A soundproof member for preventing interlayer noise of a building comprises first, second, and third soundproof panels(20,30,40), and an interception panel(50). The first soundproof panel is placed above a slab layer(10) and formed with more than one first sound suction hole(22). The second soundproof panel has second sound suction holes corresponding to the first sound suction holes. The third soundproof panel has third sound suction holes(42) corresponding to the second sound suction holes. The interception panel prevents a mortar layer(70) from being infiltrated in the third sound suction holes. Noise reducing parts are formed by the first, second, and third sound suction holes. The first, second, and third soundproof panels are formed with recessed parts(2,4), and projected parts(1,3). Separation members(24) are formed at the lower surfaces of the first soundproof panel. |
