A floor soundproof structure of a building is provided to insulate impact sound by installing a low density soundproof pad at the center of a slab and a high density soundproof pad around the outer periphery of the slab and walls. A floor soundproof structure of a building comprises a high density soundproof pad(b) and a low density soundproof pad(c). The low density soundproof pad, which does not support load of a floor direct, is constructed around the outer periphery of a slab(a). The high density soundproof pad, which supports load of the floor direct, is constructed on walls and the slab adjacent to the walls. |
