Zusammenfassung:An interfloor noise prevention structure according to one embodiment of the present invention comprises: a plurality of vibration absorption members which are arranged to be adjacent to each other on a slab in a width direction; a plurality of first floors which are arranged at the upper side of the vibration absorption members, are arranged to be adjacent to each other in the width direction, and reduce vibration delivered to the vibration absorption member; a plurality of second floors which are arranged at the upper side of the first floors, are arranged to be adjacent to each other in the width direction, and disperse vibration in the width direction; and a plurality of third floors which are arranged at the upper side of the second floors, are arranged to be adjacent to each other in the width direction, and realize insulation. The vibration absorption members comprise: a mesh unit which forms a plurality of mesh grooves; a floor impact damper in which a vibration absorption aggregate is filled to absorb vibration while being located at the lower surface of the mesh unit; and a plurality of support units which are formed at the lower surface of the mesh unit to support the mesh unit, and are spaced apart from each other in the width direction. The floor surface of the floor impact damper is formed to be lower than the floor surface of the mesh unit. The floor surface of the support unit may be formed to be lower than the floor surface of the floor impact damper. Therefore, interfloor noise may be prevented, and the insulation function may be maximized. 본 발명의 일 실시예에 따른 층간 소음방지 구조체는 슬래브 상에 폭 방향으로 복수 개가 이웃하여 배치되는 진동흡수부재; 상기 진동흡수부재의 상측에 배치되며, 상기 폭 방향으로 복수 개가 이웃하게 배치되고, 상기 진동흡수부재로 전달되는 진동을 저감하는 제1 층; 상기 제1 층의 상측에 배치되며, 상기 폭 방향으로 복수 개가 이웃하게 배치되고, 상기 폭 방향으로 진동을 분산시키는 제2 층; 및 상기 제2 층의 상측에 배치되며, 상기 폭 방향으로 복수 개가 이웃하게 배치되고, 단열을 구현하는 제3 층;을 포함하며, 상기 진동흡수부재는 다수의 메쉬홈을 형성하는 메쉬부, 상기 메쉬부의 하부면에 위치하며 진동을 흡수하도록 진동흡수골재가 충진된 바닥충격댐퍼 및 상기 메쉬부를 지지하도록 상기 메쉬부의 하부면에 형성되며, 상호 상기 폭 방향으로 이격되는 복수 개의 지지부를 구비하며, 상기 바닥충격댐퍼의 바닥면은 상기 메쉬부의 바닥면보다 더 낮게 형성되고, 상기 지지부의 바닥면은 상기 바닥충격댐퍼의 바닥면보다 더 낮게 형성될 수 있다.
