Description

바닥 충격음 저감을 위한 뜬 바닥형 공동주택의 바닥구조Floor Structure of Floating Floor Type Apartment for Reducing Floor Impact Sound

본 발명은 공동주택에서 문제시 되고 있는 상하층간 바닥 충격음을 저감시키기 위한 뜬 바닥형 공동주택의 바닥구조에 관한 것으로, 더욱 자세하게는 사람이 뛰어 다니는 소리와 같은 중량 충격음을 획기적으로 저감시킬 수 있는 개량된 뜬 바닥형 공동주택의 바닥구조에 관한 것이다.The present invention relates to a floor structure of a floating floor type apartment house for reducing the floor impact sound between the upper and lower floors, which is a problem in a multi-family house, and more particularly, an improvement capable of dramatically reducing a heavy impact sound such as a running sound of a person. It relates to the floor structure of the floating floor type apartment building.

바닥 충격음을 충격원의 유형에 따라 경량 충격음과 중량 충격음으로 분류할 경우, 지금까지 국내 공동주택에서 바닥 충격음 저감을 목적으로 적용된 매트 형태의 바닥 충격음 차음재는, 사용된 차음재의 재료에 따라 약간의 차이는 있을 수 있으나, 경량 충격음에 대한 차음성능지수가 종래 바닥구조에 비해 약 L-5 ∼ L-15 정도 개선되는 효과를 보였다. 하지만, 이는 어린아이가 뛰는 소리와 같은 중량 충격음에 대해서는 전혀 개선 효과가 없거나 미비한 실정이다.When the floor impact sound is classified into a light impact sound and a heavy impact sound according to the type of impact source, the mat-type floor impact sound insulation material applied for the purpose of reducing the floor impact sound in domestic apartment houses is slightly different depending on the material of the sound insulation material used. Although there may be, the sound insulation performance index for the lightweight impact sound has been improved by about L-5 ~ L-15 compared to the conventional floor structure. However, this has no improvement or insignificant effect on heavy impact sounds such as the sound of a child running.

공동주택의 바닥구조는 시공 순서에 따라 콘크리트 슬래브, 기포콘크리트, 몰탈 마감의 세부분으로 크게 구분되는데, 종래의 바닥 충격음을 저감시키기 위한 바닥 구조는 콘크리트 슬래브와 기포콘크리트 층 사이에 글라스울과 같은 진동 완충 재료를 설치함으로써, 상부에서 가해지는 진동을 저감시키고자 하였다.The floor structure of MDU is divided into concrete slab, foam concrete, and mortar finish according to the construction order. The floor structure for reducing conventional floor impact sound is a glass wool vibration between concrete slab and foam concrete layer. By providing a buffer material, it was intended to reduce the vibration applied at the top.

이론적으로 바닥 충격음을 저감시킬 수 있는 가장 좋은 방법은, 바닥을 이중으로 만드는 것이다. 다시 말해, 차음의 질량법칙에서 벽체의 면밀도(kg/㎡)를 두배로 할 경우, 즉 벽의 두께를 두 배로 할 경우 차음 성능은 약 6dB 증가하지만, 면밀도를 두 배로 하더라도 사이에 공간을 둔 이중벽 형태로 한다면 차음 성능은 약 15dB 이상 증가하게 된다. 이는 공기 전파음이나 바닥 충격음의 차단에 벽체의 분리가 무엇보다도 중요한 역할을 담당하는 것을 의미한다.Theoretically, the best way to reduce floor impact sounds is to make the floor double. In other words, if the wall density (kg / ㎡) is doubled in the mass law of sound insulation, that is, if the wall thickness is doubled, the sound insulation performance is increased by about 6 dB, but the double wall with space between the double wall densities In this case, the sound insulation performance is increased by about 15dB or more. This means that the separation of the wall plays an important role, among other things, to block air propagation or floor impact sounds.

종래에 사용되는 각종 바닥 충격음 저감재는 이처럼 뜬 바닥 구조를 형성하기 위한 방편의 일환으로 사용되었지만, 사용된 재료의 밀도가 낮을 경우 침하 현상에 의해 방바닥에 균열이 발생되는 문제가 있으며, 밀도가 높은 재료를 사용할 경우, 바닥 충격음 차음 성능이 저하되는 문제가 있다. 또한, 이 방식에 따라 공동주택의 슬래브 상부에 사용된 글라스울, 방진매트, 탄화코르크, 고무매트, 발포 고무매트와 같은 완충재는 사용재료가 고가인 점(㎡당 약 10,000원에서 15,000원 수준)과 함께 바닥 충격음 차음 성능을 만족할 만한 수준(경량 충격음 : 약 L-65, 중량 충격음 : 약 L-45)으로 향상시키지 못하는 문제점이 있었다.Conventionally, various floor impact sound reducing materials used in the past were used as part of the method for forming the floor structure. However, when the density of the used material is low, there is a problem that cracks occur in the floor due to the settlement phenomenon. When using, there is a problem that the floor impact sound insulation performance is degraded. In addition, cushioning materials such as glass wool, dustproof mat, carbide cork, rubber mat and foam rubber mat used in the upper part of the slab of MDU according to this method are expensive (about 10,000 won to 15,000 won per ㎡). In addition, there was a problem that the floor impact sound insulation performance could not be improved to a level that is satisfactory (light impact sound: about L-65, heavy impact sound: about L-45).

따라서, 본 발명은 상기와 같은 종래의 기술의 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 방진 고무패드와 플라스틱 팔레트를 결합한 차음재를 이용하여 공동주택의 바닥구조를 뜬 바닥형으로 형성함으로써, 사람이 뛰어 다니는 소리와 같은 중량 충격음을 획기적으로 저감시킬 수 있는 개량된 뜬 바닥형 공동주택의 바닥구조를 제공하는데 있다.Therefore, the present invention has been made to solve the problems of the prior art as described above, the object of the present invention by forming a floor structure of the floor structure of the multi-family housing using a soundproofing material combined with a dustproof rubber pad and a plastic pallet. In addition, the present invention provides a floor structure of an improved floating floor type apartment house that can significantly reduce a heavy impact sound such as a person running around.
