The present invention relates to a sound insulation member installed between a floor slab and a floor decoration member to reduce noise generated between floors. The sound insulation member is formed as a first panel unit and a second panel unit, which are formed at fixed thicknesses, are vertically stacked. The first panel unit is located in the lower part. The upper surface of the first panel unit is flat, and the lower surface is formed in a solid form of a plate shape, which is treated to be continuously uneven at fixed intervals. The second panel unit is connected onto the first panel unit, and both upper and lower sides of the second panel unit have the solid form of the flat plate shape. Moreover, the first and second panel units of the sound insulation member are individually formed of a second-class insulation material of a bead method in the thickness of 20 mm. The density of the first panel unit is smaller than the density of the second panel unit. The sound insulation member for reducing floor noise efficiently satisfies a blocking effect on the floor noise by simply connecting a plate-shaped panel member and an uneven surface panel member, which are formed at fixed thickness, and installing the connected members in a floor structure. |
