A structure for preventing noise transfer between floors of a building is provided to create noise buffering space for absorbing noises by installing plural height adjusting devices between plasterwork and a reinforcing plates, thereby effectively preventing the noise from an upper floor from being transmitted to a lower floor. A structure for prevent noise transfer between floors of a building includes a floor layer(20) having a 24mm thick plasterwork(22) plastered on a concrete slab(21), and plural height adjusting devices(29). The height adjusting devices are installed on an upper part of the floor layer with preset gaps between each height adjusting devices. Supporting plates(23), having plural through-holes, are fixed on the plasterwork by nails. Bolts(26) are welded at centers of each of the supporting plates. Supporting parts(28), having nut grooves, are coupled to the bolts. The height of the supporting parts can be adjusted depending on the coupling depth of the bolts and the nut grooves. A reinforcing plate(31) is installed on upper sections of the supporting parts. The reinforcing plates create a space below the reinforcing plates. The space is capable of buffering the inter floor noises. Coupling units(33) for holding Ondol pipes(32) are fixed to the underside of the reinforcing plates by screw bolts(35). A wooden floor is installed on the reinforcing plate. |
