The present invention relates to an apparatus for preventing a noise between floors. According to the present invention, an upper plate having grooves which consist of a checker pattern part, where a heating pipe is mounted on an upper part, is combined with a lower supporting plate having a filling grooves filled with sound absorption insulation. Multiple upper plates and lower supporting plates assembled on mortar are installed on an interlayer cement floor of an apartment or a multiplex house vertically having multiple floors, and the heating pipe is installed on the upper part thereof and finished with finish mortar. Therefore, an impact borne sound generated on an upper floor is absorbed into filling grooves, which have the sound absorption insulation, of the lower supporting plate, so amplification of a noise between floors is prevented, and transferring noise from an upper floor to a lower floor is prevented. Moreover, the register amplification phenomenon due to volume reproduction of a residual register of the impact borne sound transferred from the upper floor is completely removed, so generation of a noise between floors from the upper floor to the lower floor is fundamentally prevented. |
