The present invention relates to a light weight panel for preventing noise between floors and a soundproof floor structure using the same. More specifically, a light absorbing path is formed on a floor lightweight panel installed in a slab, and a discharge hole is provided at a side contacting the floor lightweight panel. By installing the formed wall buffer to communicate the sound absorbing path and the discharge hole, the light and heavy sound transmitted between the floors are collected in the sound absorbing path to be re-delivered to the room through the exhaust hole of the wall buffer to reduce the noise transmitted between floors. The present invention relates to a light weight panel for preventing noise between floors and a sound insulating floor structure using the same.

Impact sounds from multi-storey townhouses, multi-family houses and apartments are transmitted to neighboring households through floors and walls. These impact sounds are classified into light impact sounds generated by falling objects or impacts on the floor when moving furniture, and heavy impact sounds generated by heavy impacts such as when children are running. It is a problem because it is easily delivered to neighboring households.

Particularly, in the case of multi-unit houses in Korea, the slab layer, the insulation layer on the upper slab, the light concrete or foam concrete layer, the heating coil layer and the finishing mortar layer including a finishing mortar layer, the insulation layer to a certain degree in addition to the use of heat insulation By using the foamed polystyrene (styropole) which has the effect of blocking the floor impact sound of the construction without the use of a separate noise shielding material is a situation that the effect of reducing the impact sound is insufficient.

In order to block such impact sound, Republic of Korea Utility Model Registration No.0402807 has a plurality of hollows in the floor structure by forming a foamed polyethylene sheet layer and a polypropylene hollow plate layer in which a perforated layer is formed between foamed polyethylene layers in a floor structure that blocks interlayer noise. It forms a part to block the transmission of the impact sound.

The conventional method is to obtain the effect of attenuating the vibration and impact sound by using the perforated layer of the laminated polyethylene sheet layer and the empty space formed in the hollow plate layer of the polypropylene. In other words, the vibration and impact sound transmitted between the layers to be transmitted by the parallax for noise reduction due to distributed transmission. This method has a problem in that a substantial noise generator is not aware of the magnitude of vibration noise, and there is a problem that noise is generated for a predetermined time as transmitted by parallax.

By installing a wall buffer to communicate the sound absorbing path of the discharge hole and the light weight panel, the light weight and heavy sound transmitted between the layers are collected in the sound absorbing path, and the light and heavy sound collected are moved upward through the discharge hole communicating with the sound absorbing path. It is an object of the present invention to provide a light weight panel and a soundproof floor structure that minimizes the transmission of noise between floors by discharging a part of the noise transmitted to the lower floor, such as the upper floor.
