Description
본 고안은 층간소음방지재에 관한 것으로서, 우리나라 공동주택은 통상 두께 120 내지 200mm의 콘크리트로 이루어진 벽체 및 바닥이 연결되어 하나의 구조체로 구성되는 벽식구조가 대부분이다. 이러한 콘크리트 구조는 재료의 특성상 강성이 있고 밀실이기 때문에 TV음 등 공기를 매체로 전달되는 공기 전달음에 대해서는 충분한 차단성능을 갖고 있다.The present invention relates to an interlayer noise prevention material, the Korean apartment house is usually a wall structure consisting of a single structure is connected to the wall and floor made of concrete of 120 to 200mm thick. Since the concrete structure is rigid and closed in nature of the material, the concrete structure has sufficient blocking performance against the air transmission sound transmitted to the medium such as TV sound.
그러나 콘크리트에 충격이 가해질 때 발생되는 고체 전달음의 경우 콘크리트는 자체 진동감쇄능력이 떨어지기 때문에 인접 세대로 쉽게 전달되는 특성을 갖고 있다.However, in the case of a solid transmission sound generated when an impact is applied to the concrete, the concrete has a characteristic of being easily transmitted to an adjacent generation because its vibration damping ability is inferior.
현재 이러한 층간소음을 저감할 수 있는 방법으로 충격원이 발생하는 곳에 층간소음방지재를 설치하게 되는데, 일반적인 건축물의 단면을 살펴보면 슬래브층, 경량기포콘크리트층, 마감몰탈층, 바닥마감재층이 차례로 구성되어 있으며, 슬래브층과 경량기포콘크리트층 사이에 층간소음방지재를 설치하여 슬래브 상단의 구조가 뜬바닥 구조가 형성되도록 하여 소음·진동을 방지하는 시스템을 통상적으로 사용하고 있다.Currently, the interlayer noise prevention material is installed in the place where the impact source is generated as a way to reduce the noise between the floors. Looking at the cross-section of the general building, the slab layer, the lightweight foam concrete layer, the finishing mortar layer, and the floor finish layer are sequentially formed. The interlayer noise prevention material is installed between the slab layer and the lightweight foam concrete layer so that the structure of the top of the slab is made of floating floor structure.
종래에도 가교발포폴리에틸렌시트의 단열보온성, 차음·완충성, 내화학성 및 비흡습성 등의 우수한 특성을 이용하여 산업 전반에 보온단열재, 충격흡수재, 완충재, 흡음재 등 다양한 용도로 이용되고 있으며, 특히 근래에는 공동주택에서의 세대간, 층간 소음을 저감하기 위한 목적으로 그 사용이 증가되고 있으며 여러 가지 형상으로 개발되어지고 있는 상황이다.Conventionally, it has been used in various industries such as thermal insulation, shock absorber, shock absorber, sound absorbing material by using excellent properties such as thermal insulation insulation, sound insulation, shock resistance, chemical resistance and non-hygroscopicity of crosslinked foamed polyethylene sheet. In order to reduce intergenerational and floor noise in multi-family housing, its use is increasing and it is being developed in various shapes.
본 고안은 건축물의 주거경계간 특히 상하층간에 발생되는 충격음 또는 진동음을 최소화하여 쾌적한 주거환경을 제공하기 위한 층간소음방지재에 관한 것으로, 공동주택에서의 소음은 크게 공기전달음과 고체전달음으로 구분되는데 전자의 경우 말소리나 TV소리 등 공기를 매체로 하여 전달되는 소음으로 콘크리트와 같은 구조물에 의하여 충분히 차단할 수 있으나, 후자의 경우 위층에서 뛰는 소리, 물건 떨어지는 소리 등이 대표적이며 하나의 진동원에서 발생한 진동이 건축구조물를 통해 건물의 천장, 바닥, 벽 등으로 전파되어 사람의 청각으로 감지되는 것으로 적절한 소재와 형상을 가지는 완충재를 사용하여 뜬바닥구조 등의 시스템을 통해서 소음을 해결하여야 한다.The present invention relates to a floor noise preventing material for providing a pleasant living environment by minimizing the impact sound or vibration sound generated between the residential boundaries of buildings, especially between the upper and lower floors. In the former case, the sound transmitted through air such as speech or TV sound can be sufficiently blocked by a structure such as concrete. In the latter case, the sound of running upstairs and falling sound of the object is typical. The generated vibration propagates through the building structure to the ceiling, floor, and wall of the building and is sensed by human hearing. The noise must be solved through the system of floating floor using a cushioning material with appropriate material and shape.
본 고안의 층간소음방지재는 건축물의 슬래브 상단에 설치하여 층간·세대간 소음 및 진동을 저감시키기 위한 것으로, 일반적인 건축물의 단면을 살펴보면 슬래브층, 경량기포콘크리트층, 마감몰탈층, 바닥마감재층이 차례로 구성되어 있는데, 슬래브층과 경량기포콘크리트층 사이에 층간소음방지재를 설치하여 슬래브 상단의 구조가 뜬바닥 구조가 형성되도록 하여 소음·진동을 방지하게 되며, 본 고안은 이러한 소음방지기능을 극대화하기 위해 상하층에 다수 개의 타공체를 형성시킨 구조로서 하층부의 타공체는 슬래브면과의 접촉면적을 최소화시킴과 동시에 다수의 공기층을 형성시켜 상부에서 전달되는 소음 또는 진동을 분산, 흡수하도록 하고, 상층부의 타공층은 층간소음방지재 상단에 경량기포콘크리트를 타설시 크랙(crack) 등의 구조적 결함이 발생될 우려가 있는데 이를 최소화시킬 수 있도록 고안되어진 것이다.The floor noise prevention material of the present invention is installed on the top of the slab of the building to reduce the noise and vibration between floors and generations. Looking at the cross section of the general building, the slab layer, the light foam concrete layer, the finishing mortar layer, and the floor finishing material layer are sequentially The interlayer noise prevention material is installed between the slab layer and the lightweight foam concrete layer to prevent the noise and vibration by forming the floating bottom structure of the top of the slab, and the present invention maximizes the noise prevention function. In order to minimize the contact area with the slab surface and to form a plurality of air layers, the perforated body of the lower layer is formed in the upper and lower layers to disperse and absorb the noise or vibration transmitted from the upper layer. Perforated layer is structurally cracked when light weight foam concrete is placed on top of the interlayer noise prevention material. There is a possibility that the box is generated is designed to minimize it.
