FLOOR IMPACT SOUND BLOCKING PANEL AND SLAB STRUCTURE FOR BLOCKING INTER-FLOOR IMPACT SOUND AND SLAB CONSTRUCTION METHOD

The present invention relates to a floor impact sound blocking panel, an inter-floor impact sound blocking slab structure for noise prevention, and a slab construction method. In particular, the impact sound generated from the upper part after construction does not spread horizontally from shock absorption cells of a finishing mortar layer and is blocked, and unlike conventional floor slab structures, there is no lightweight foam concrete layer, thereby enabling simple construction and reducing construction costs. The floor impact sound blocking panel of the present invention, in which various shapes of partition walls (W) are formed to form various shapes of impact sound absorption cells (C) in a panel body (10), comprises a plurality of elliptical walls (120) provided in the inner center of an edge wall (110) of the panel body (10), and a plurality of semi-elliptical walls (130) on the left and right sides of the elliptical walls (120). 이 건 발명은 바닥충격음 차단 패널, 소음방지를 위한 층간 바닥충격음 차단 슬래브 구조 및 슬래브 시공방법에 관한 것으로서, 특히 시공 후 상부로부터 발생되는 충격음이 마감 모르타르층의 충격 흡수셀에서 수평방향으로 확산되지 아니하고 차단되어질 뿐만 아니라, 종래의 층간 바닥충격음 바닥 슬래브 구조와는 달리 경량기포 콘크리트층이 없어 시공이 간단하고 시공비가 절감될 수 있도록 한 것이다.
