A noise prevention structure between two stories is provided to effectively absorb vibration and impact noise transferred to the slab by reducing the noise through the lattice-type wood supported at the lower floor. A noise prevention structure of an interlayer slab is composed of a noise prevention layer(120) containing a waterproof member(122), a lattice-type frame(123) formed with a Ý‹-shaped channel(123a) at the lower side, and a vibration proof rubber member(124) placed between the Ý‹-shaped channel and the slab; a heating noise prevention layer(130) laminated on the noise prevention layer to place a noise prevention net(133) at a predetermined height piping a predetermined heating pipe(131) and fill a cement mortar(134) and deposited with a floor decorative material(160); and a gap and a hole communicated with a space formed at the lower side of the noise prevention layer. |
