Zusammenfassung:The present invention relates to a composite buffering structure for reducing a floor impact sound with double air layers, which is able to have bump units respectively formed on a lower surface of a lower buffering material and a lower surface of an upper buffering material, which are installed on an upper side of a floor slab in order, reduce the floor impact sound, and prevent the performance from decreasing due to the sagging. According to the present invention, the composite buffering structure for reducing a floor impact sound with double air layers comprises: a lower buffering material installed on the upper side of a floor slab for reducing the floor impact sound, and having a plurality of bump units formed on the lower side and having a first air layer formed between adjacent first bump units; and an upper buffering material stacked on the upper side of the lower buffering material and having a plurality of second bump units formed on the lower side and having a second air layer formed between adjacent second bump units. 본 발명은 바닥슬래브 상부에 차례로 설치되는 하부완충재와 상부완충재의 하면에 각각 돌부가 형성되어 이웃하는 돌부와의 사이에 공기층을 형성함으로써, 바닥충격음을 저감하면서도 처짐으로 인한 성능 저하를 방지할 수 있는 이중공기층이 구비된 바닥충격음 저감용 복합완충구조에 대한 것이다. 본 발명 이중공기층이 구비된 바닥충격음 저감용 복합완충구조는 바닥충격음을 저감하기 위해 바닥슬래브의 상부에 설치되는 것으로, 하부에 복수의 제1돌부가 돌출 형성되어 이웃하는 제1돌부 사이에 제1공기층이 형성되는 하부완충재; 및 상기 하부완충재의 상부에 적층되는 것으로 하부에 복수의 제2돌부가 돌출 형성되어 이웃하는 제2돌부 사이에 제2공기층이 형성되는 상부완충재; 로 구성되는 것을 특징으로 한다.
