공동 주택용 층간 소음 방지 건축 슬래브 구조{CONSTRUCTION SLAB STRUCTURE FOR INTERLAYER NOISE PREVENTION OF APARTMENT BUILDING}CONSTRUCTION SLAB STRUCTURE FOR INTERLAYER NOISE PREVENTION OF APARTMENT BUILDING

본 발명은 공동 주택용 층간 소음 방지 건축 슬래브 구조에 관한 것으로서, 상세하게는 내부에 액체가 충전되면서 상부에 공기층을 구비하는 흡차음 부재를 설치하고, 흡차음 부재의 저면에 다리를 형성하여 2개의 공기층과 1개의 액체층을 형성하여 층간소음 능력을 상대적으로 향상시키도록 하는 공동 주택용 층간 소음 방지 건축 슬래브 구조에 관한 것이다.The present invention relates to an inter-floor noise prevention building slab structure for a multi-family house, and more particularly, by installing a sound absorbing and insulating member having an air layer on the upper part while filling the inside with a liquid, and forming a bridge on the bottom surface of the sound absorbing and insulating member to form two air layers It relates to an inter-floor noise prevention building slab structure for a multi-story house, which forms one liquid layer and relatively improves the inter-floor noise capability.

현재 국내의 경우, 아파트, 빌라, 다세대와 같은 공동주택이 많이 건축되어 있고, 이러한 공동주택의 층간소음 및 진동으로 인한 불편은 공동주택만의 특유한 불편사항으로 지적되고 있다. 특히, 벽체와 바닥을 이웃세대와 공유하여야 하는 공동주택의 경우, 실내에서의 보행이나 아이들의 뜀박질, 물체의 낙하, 기타 가구 등의 이동으로 인해 바닥에 가해지는 바닥충격음이 하층에 전달되는데, 이러한 층간소음 및 진동은 쾌적하고 조용한 환경에서 휴식하기를 원하는 이웃 간에 불미스러운 일을 야기하고 있는 실정이다.Currently, in Korea, a lot of apartment houses, such as apartments, villas, and multi-family houses are built, and the inconvenience caused by noise and vibration between floors in these apartment houses is pointed out as a unique inconvenience of apartment houses. In particular, in the case of an apartment house where walls and floors must be shared with neighboring households, the floor impact sound applied to the floor is transmitted to the lower floors due to indoor walking, children's running, falling objects, and moving furniture, etc. The noise and vibration between floors is a situation that causes unpleasant things between neighbors who want to rest in a pleasant and quiet environment.

이에 따라, 정부는 "주택건설 기준 등에 관한 규정"을 개정하여 공동주택, 특히, 아파트의 층간소음을 줄이기 위한 바닥충격음 기준을 새롭게 정비하였다. 이러한 규정에 따르면 공동주택의 층간 바닥충격음의 기준을 작은 물건이 떨어지는 정도의 경량 충격음과 어린이가 뛰는 정도의 중량 충격음으로 각각 구분하여 향후 신축되는 공동주택에 적용하도록 하고 있다. 이러한 바닥충격음 기준은 식탁의자를 끄는 소리가 아래층에 들리지 않고, 어린이가 뛰어다니는 소리가 불쾌감을 주지 않을 정도의 수준을 말한다.Accordingly, the government revised the "Regulations on Housing Construction Standards, etc." to reorganize the floor impact sound standards to reduce the noise between floors in apartment houses, especially apartments. According to these regulations, the standard for floor impact sound between floors in an apartment building is divided into a light impact sound of the degree of falling of a small object and a heavy impact sound of the degree of a child jumping, and it is applied to new apartment houses in the future. The standard for floor impact sound refers to a level at which the sound of dragging a table chair is not heard downstairs, and the sound of children running around does not cause discomfort.

한편, 도 1은 일반적인 공동주택의 바닥 구조를 나타내는 단면도이다.Meanwhile, FIG. 1 is a cross-sectional view showing the floor structure of a general apartment house.

도 1에 도시된 바와 같이, 일반적인 공동주택의 바닥 구조는, 벽체(11) 하부의 콘크리트 바닥슬래브(12) 상에 완충재(21), 기포 콘크리트(22), 마감 모르타르(23) 및 바닥 마감재(24)를 순차적으로 적층하여 시공하고 있다. 특히, 국내의 경우, 콘크리트 바닥슬래브(12)는 1999년까지는 120㎜였지만, 현재 210㎜로 시공되고 있다.As shown in Figure 1, the floor structure of a general apartment house is a cushioning material 21, aerated concrete 22, a finishing mortar 23 and a floor finishing material on the concrete floor slab 12 under the wall 11. 24) are sequentially stacked and constructed. In particular, in the case of Korea, the concrete floor slab 12 was 120 mm until 1999, but is currently being constructed with a thickness of 210 mm.

구체적으로, 현재의 대부분의 시공현장에서는 중량 충격음에 대한 법적인 요건을 충족하기 위하여 표준바닥 구조를 적용하는 것이 일반적이다. 구체적으로, 표준바닥 구조는 바닥충격음 저감을 위해 슬래브 두께를 증가시킨 방식인데, 예를 들면, 벽식 구조의 경우, 콘크리트 바닥슬래브 두께를 210㎜로 시공하고 있다. 그러나 이러한 표준바닥 구조는 통상 구조 안전성을 위하여 요구되는 슬래브 두께보다 두껍게 시공하는 방식이기 때문에, 콘크리트의 사용량을 증대시키고, 건물 자중을 증대시키며, 또한, 건물의 유효 층고 감소 등의 문제가 필연적으로 뒤따른다는 문제점이 있다.Specifically, in most current construction sites, it is common to apply a standard floor structure to meet the legal requirements for heavy impact sound. Specifically, the standard floor structure is a method in which the thickness of the slab is increased to reduce the floor impact sound. For example, in the case of a wall structure, the thickness of the concrete floor slab is 210 mm. However, since this standard floor structure is usually constructed thicker than the slab thickness required for structural safety, problems such as increasing the amount of concrete used, increasing the weight of the building, and reducing the effective floor height of the building are inevitably followed. There is a problem with everything.

최근 정부도 층간소음을 잡기 위해 노력하고 있는 데, 국토교통부는 대형 건설사들과 바닥 슬래브(철근 콘크리트) 두께를 기존 210㎜에서 240㎜로 의무화하는 방안을 논의하기도 했다.Recently, the government is also trying to catch the noise between floors, and the Ministry of Land, Infrastructure and Transport has discussed with large construction companies a plan to make the thickness of floor slabs (reinforced concrete) from 210 mm to 240 mm.

한편, 이러한 층간소음 방지를 위한 바닥 구조로 국내 등록특허 제10-2255604호인 층간소음 저감을 위해 벽체-고정 강선케이블을 이용한 뜬바닥 구조체 및 그 시공 방법, 제10-2248256호인 층간소음 저감을 위한 건축용 바닥 구조체, 제10-2301084호인 층간소음 방지 건축 슬라브구조 등이 게시되어 있다.On the other hand, as a floor structure for preventing noise between floors, a floating floor structure using a wall-fixed steel wire cable for noise reduction between floors, which is a domestic registered patent No. 10-2255604, and its construction method, and a construction method for reducing noise between floors, No. 10-2248256 Floor structures and inter-floor noise prevention building slab structures, No. 10-2301084, are posted.

이러한 바닥 구조는 슬래브 상면에 공간을 형성하는 뜬바닥 형태인 데, 강선이나 완충재, 응력분산층 등을 두어 층간소음을 저감하는 것인 데, 대부분 공기층과 차음, 흠음재만을 이용하여 층간소음을 저감하기 때문에 저감 능력이 상대적으로 떨어지는 문제점이 있다.This floor structure is in the form of a floating floor that forms a space on the upper surface of the slab. It reduces noise between floors by placing steel wires, cushioning materials, and stress distribution layers. Therefore, there is a problem that the reduction ability is relatively low.
