Zusammenfassung:Disclosed is a floor noise prevention assembly. A floor noise prevention assembly according to an embodiment of the present invention includes: a noise damping unit arranged along a floor slab of a building and composed of parts with different porous ratios to damp low frequency noise generated by impacts from the upper side of the floor slab; a contact unit protruding from the lower part of the noise damping unit and be partly in contact with the floor slab; a buffering unit formed on the outer circumference of the contact unit and having an auxiliary damping unit additionally damping the low frequency noise which has passed through the noise damping unit; and a guide unit guiding the low frequency, which has passed gone through the buffering unit, to an indoor space. The purpose of the present invention is to prevent a problem caused by floor noise by damping the low frequency noise again in the indoor space after damping low frequency noise to the utmost. 층간 소음 방지 조립체가 개시된다. 본 발명의 일 실시 예에 따른 층간 소음 방지 조립체는 건물의 바닥 슬래브를 따라 배열되고 상기 바닥 슬래브의 상부에서 가해진 충격에 의해 발생된 저주파 소음을 감쇠하기 위해 서로 다른 공극률로 이루어진 소음 감쇠부와, 상기 소음 감쇠부의 하단에 돌출되고 상기 바닥 슬래브와 부분 접촉되는 접촉부와, 상기 접촉부의 외주면에 형성되고 상기 소음 감쇠부를 경유한 저주파 소음을 추가로 감쇠하기 위한 보조 감쇠부를 포함하는 완충부; 및 상기 완충부를 경유한 저주파 소음을 실내로 유도하는 유도부를 포함한다.
