본 발명은 복층건물의 층간 소음방지체의 적층구조에 관한 것으로, 더욱 상세하게는 복층건물의 층간 슬래브 상에 합성부직포, EPP, 고비중 차음재 및 버블시트층을 적층하여 상층으로부터 해당층으로 전달되는 각종 바닥충격음, 공명음 또는 진동을 흡음, 차음 및 제진할 수 있도록 한 층간 소음방지체의 적층구조에 관한 것이다.The present invention relates to a laminated structure of an interlayer noise suppressor of a multi-storey building, and more particularly, a composite nonwoven fabric, an EPP, a high specific sound insulation material, and a bubble sheet layer are laminated on an interlayer slab of a multi-storey building to be transferred from an upper layer to a corresponding layer. The present invention relates to a laminated structure of an interlayer noise prevention body capable of absorbing, insulating, and damping various floor impact sounds, resonance sounds, or vibrations.

최근 주택 및 사무실의 수요가 증가함에 따라, 건물의 고층화와 고밀도화가 요구되고 있는 반면에, 건물의 시공에 소요되는 원가를 절감하기 위해 벽 및 바닥을 형성하는 재료의 두께는 점차 경량화 및 슬림화되어 가고 있는 실정이다.Recently, as the demand of houses and offices increases, the height and density of buildings are required, while the thickness of the walls and floors is becoming lighter and slimmer to reduce the cost of building. There is a situation.

그러나, 경량화 및 슬림화 된 재료는 토지 이용의 고밀도화에 따른 외부 소음원과 주거 설비의 수요 증대에 기인한 내부 소음원을 효과적으로 차단할 수 없어 쾌적한 환경에 대한 수요자의 욕구를 만족시키지 못하고 있다.However, lightweight and slimmer materials cannot effectively block internal noise sources due to increased demand for land and residential facilities due to higher density of land use, and thus do not satisfy the needs of consumers for a pleasant environment.

특히, 이웃과 벽체 및 바닥을 공유해야 하는 공동주택의 경우 콘크리트 재료의 특성 때문에 공동주택의 각 세대간에 발생하는 공명음, 예컨대 대화소리, TV 소리, 음악소리 등에 대해서는 일정한 수준의 소음 저감 성능이 있는 반면, 바닥충격음 중 중량충격음, 예컨데 구두소리, 아이들 뛰는 소리, 물건이 떨어지는 소리 등에 대해서는 저감효과가 거의 없는 실정이다.In particular, in the case of a multi-family house that needs to share walls and floors with its neighbors, there is a certain level of noise reduction performance for resonance sounds, such as conversational sounds, TV sounds, and music sounds, which occur between generations of multi-family houses due to the characteristics of concrete materials. On the other hand, heavy impact sound, such as shoes, running children, sound of falling objects, etc. of the floor impact sound has little effect.

따라서, 층간 발생하는 중량충격음 계통의 소음이 입주자의 불만을 유발하여 차음 성능이 주거여건을 결정하는 중요한 인자로 작용하고 있으며, 나아가 인접 세대간 소음 분쟁을 일으키는 원인이 되고 있다.Therefore, the noise of the heavy impact sound system generated between floors causes tenant's dissatisfaction, and the sound insulation performance is an important factor in determining the living conditions, and also causes noise disputes between adjacent generations.

이러한 문제점을 해결하기 위해 최근에는 콘크리트 슬래브층과 경량 기포콘크리트층 사이에 바닥 충격음 저감용 완충재를 개재하고 있지만, 이러한 완충재의 경우 스티로폼과 같이 일정한 두께의 합성수지 발포체로서 기존의 단열재를바닥충격음 저감용으로 대체 사용한 것이기 때문에, 단열성능은 우수하나 중량충격음과 같은 바닥충격음에 대한 저감 효과는 미미하였다.In order to solve this problem, a cushioning material for reducing floor impact sound is interposed between a concrete slab layer and a lightweight foam concrete layer. However, such a cushioning material is a synthetic resin foam having a constant thickness, such as styrofoam. Since it was used as an alternative, the thermal insulation performance was excellent, but the reduction effect on the floor impact sound such as the weight impact sound was minimal.

즉, 기존의 중량충격음과 같은 바닥충격음 저감용 완충재는 판상구조로 되어 있어, 완충재의 상부면은 기포콘크리트 층 전체 면적과, 하부면의 경우 슬래브 층 전체와 면적 접촉하기 때문에, 상하층간 충격음이 거의 저감되지 않은 채 그대로 전달되는 문제점이 있었다.That is, the shock absorber for reducing the bottom impact sound, such as the existing heavy impact sound, has a plate-like structure, and since the upper surface of the buffer material contacts the entire area of the foam concrete layer and the entire surface of the slab layer, the impact sound between the upper and lower layers is almost There was a problem that is delivered as it is not reduced.

따라서, 본 발명의 목적은, 복층건물의 층간 슬래브 상에 합성부직포, EPP, 고비중 차음재 및 버블시트층을 적층하여 상층으로부터 해당층으로 전달되는 각종 바닥충격음, 공명음 또는 진동을 흡음, 차음 및 제진 할 수 있도록 한 층간 소음방지체의 적층구조를 제공하는 것이다.Accordingly, an object of the present invention is to laminate the composite nonwoven fabric, EPP, high specific sound insulation material and bubble sheet layer on the interlayer slab of a multi-storey building to absorb various sound waves, resonance sound or vibration transmitted from the upper layer to the corresponding layer. It is to provide a laminated structure of an interlayer noise suppressor to be damped.
