UPPER IMPACT SOUND PREVENTION SYSTEM

摘要

PURPOSE: An upper impact sound prevention system is provided to prevent impact sound, produced from an upper floor of a lower layer, from being transmitted to a lower floor and to improve thermal insulation effect of an upper layer and the lower layer by forming a space part between a slab and a floor material. CONSTITUTION: An upper impact sound prevention system includes plural panels(20) supporting the bottom of a floor material(9); plural blocks(50) combined to plural spots in the longitudinal direction of the panels; vibroisolating materials disposed between the panels and the blocks; and screws(60). The panels are disposed on the top in parallel. An internal thread hole is formed at the bottom. The front end of the screw is combined to the internal thread hole of the block and the rear end is adhered closely to the top of a slab(1). The rear end of the screw transfers the block in the vertical direction through rotation. The panels are spaced from the top of the slab by the screws.
