Description

층간소음방지용 바닥구조{Floor structure for noise absorption between floors}Floor structure for noise absorption between floors

본 발명은 층간소음용 바닥구조에 관한 것으로서, 더욱 상세하게는 건축물의 바닥 슬라브로 전달되는 층간소음을 다수개의 차음공을 형성한 차음판을 상부에 마련한 차음판을 경량콘크리트 내부에 마련하도록 하여 바닥에서 발생되는 층간소음이 하부로 전달되어 차음판의 다수개 차음공을 거치면서 층간소음의 울림을 분리 및 차음공의 외부로 확산되지 않도록 하면서 층간소음을 절감시키게 하는 층간소음방지용 바닥구조에 관한 것이다.The present invention relates to a floor structure for inter-floor noise, and more particularly, to provide a sound-insulating plate in which a sound-insulating plate having a plurality of sound-insulating holes formed thereon is provided inside the lightweight concrete for inter-floor noise transmitted to the floor slab of a building. The present invention relates to a floor structure for interlayer noise prevention that reduces inter-layer noise while separating the interlayer noise from being transmitted to the bottom and passing through a plurality of sound insulation holes of the sound insulation plate and not spreading it to the outside of the sound insulation hole. .

일반적으로 공동주택 바닥구조는 콘크리트 슬라브 상부 면에 단열성능을 위한 경량기포콘크리트를 타설한 후, 상부 면에 난방배관을 설치하여 시멘트 마감모르타르로 마감하는 바닥구조는 층간소음에 매우 취약하여 최근에 이를 개선하기 위하여 바닥 슬라브 두께를 증가시키거나 또는 뜬 바닥구조의 적용이나 연질계통 위 완충재를 적용하는 사례가 늘고 있고 더불어 층간소음을 줄이기 위해서 탄성률이 적은 폐타이어 칩이나 우레탄 폼 등의 완충재를 설치하여 층간소음의 줄이기 하려는 노력을 하고 있다. 일부 시스템에서는 슬라브 상부에 공간 층을 두고 상부에는 플라스틱 패널과 단열재를 일체화하여 시공하고 있다.In general, the floor structure of an apartment house is a floor structure in which light-weight foamed concrete is placed on the upper surface of the concrete slab for insulation performance, and then a heating pipe is installed on the upper surface to finish with cement-finished mortar. Increasing the thickness of the floor slab or applying a floating floor structure or a cushioning material on a soft system is increasing in order to improve it.In addition, in order to reduce the interlayer noise, a cushioning material such as waste tire chips or urethane foam with a low elastic modulus is installed between layers. Efforts are being made to reduce noise. In some systems, a space layer is placed on the upper part of the slab, and a plastic panel and insulation are integrated on the upper part.

상기와 같은 건축물의 실내 바닥구조는 철근 콘크리트 슬라브 상면에 경량콘크리트를 마련하여 층간 소음을 감쇄시키는 작용을 하고 있으나 그 소음 감쇄작용 효과는 그다지 뛰어나지 않은 관계로 각종 충격음에 따른 소음을 제대로 흡수, 차단하지 못하는 문제점을 가지고 있다.The indoor floor structure of the above building has a function of attenuating inter-floor noise by providing lightweight concrete on the upper surface of the reinforced concrete slab, but the noise attenuating effect is not so excellent, so it does not properly absorb and block noise from various impact sounds. It has a problem that cannot be done.

그리고, 차음과 단열 성능을 함께 구비한 경량콘크리트 개발은 1996년 이후 최근까지 수많은 업체에서 지속적으로 연구 개발하고 있는 분야로서, 기존 경량콘크리트 시멘트 슬러리에 비중이 서로 다른 재료, 예를 들어 폴리에틸렌 비닐 아세테이트 코폴리머 칩(Poly ethylene-vinyl acetate copolymer chip), 폴리우레탄 칩(Poly urethane chip), 고무 칩(Rubber chip)등의 소재나 초경량 소재인 폴리 에틸렌 비닐 아세테이트 코폴리머 폼 칩(Poly ethylene-vinyl acetate copolymer foam chip), 폴리우레탄 폼 칩(Poly urethane foam chip), 폴리스티렌 폼 칩(Expandable poly styrene chip : EPS chip), 중공이 있는 발포 필러(Filler)등을 1 내지 3종을 혼합하여 제조되었으나, 서로 다른 재료의 비중 차이로 침전, 부유, 분리, 쏠림 등의 현상으로 현장 타설에 실패하거나, 균질한 제품을 만들 수 없어 중도 포기한 사례가 매우 많았다.In addition, the development of lightweight concrete with sound insulation and insulation performance is a field that has been continuously researched and developed by numerous companies since 1996, and materials with different specific gravity to the existing lightweight concrete cement slurry, for example, polyethylene vinyl acetate co. Materials such as polymer chips (Poly ethylene-vinyl acetate copolymer chips), polyurethane chips (Poly urethane chips), rubber chips (Rubber chips), and ultra-lightweight materials such as polyethylene-vinyl acetate copolymer foam (Poly ethylene-vinyl acetate copolymer foam) chip), polyurethane foam chip (Poly urethane foam chip), polystyrene foam chip (Expandable poly styrene chip: EPS chip), hollow foam filler (Filler), etc. 1 to 3 types are mixed, but different materials Due to the difference in specific gravity, there were many cases of failure to place on-site due to phenomena such as sedimentation, floating, separation, and pulling, or were abandoned due to the inability to make a homogeneous product.

이는 경량콘크리트의 특성이 사람의 음성 및 각종 음향기기 등에서 발생하는 기체전달 소음에 대한 감쇄작용은 뛰어나지만, 상층바닥에서 사람의 보행, 물건 등의 낙하로 발생하는 고체전달 소음을 감쇄시키고 차단하는 능력은 떨어지기 때문이다.This is because the characteristics of lightweight concrete are excellent in attenuating gas transmission noise generated by human voice and various acoustic devices, but the ability to attenuate and block solid transmission noise caused by walking of people and falling objects on the upper floor. Because is falling.

그리고, 공동주택의 바닥구조가 층간소음을 효과적으로 흡수, 차단시켜주지 못하고 있는 문제점으로 인하여 상하층에 거주하는 거주인들 간의 분쟁이 발생하는 등 층간소음으로 인한 문제가 점점 심각해지고 있어 최근에는 공동주택 상하층 간의 층간소음을 줄여주는 저감재의 사용이 의무화되기에 이르렀다.In addition, due to the problem that the floor structure of apartment houses does not effectively absorb and block inter-floor noise, disputes between residents living in the upper and lower floors have arisen, and problems caused by inter-floor noise are becoming more and more serious. The use of a reduction material that reduces the inter-floor noise between the upper and lower layers has become mandatory.

상기 콘크리트 슬라브는 상층의 충격 및 소음을 그대로 하층으로 전달시키기 때문에 층간소음을 차단할 필요가 있으며, 층간소음을 차단하기 위해서 통상 수지 재료로 형성된 소음방지재가 상기 콘크리트 슬라브와 단열재 사이에 위치되나 상기 소음방지재는 상부에 위치되는 열교환파이프, 시멘트 및 미장층으로부터 가해지는 압력으로 진동과 소음을 차단하는 효과가 낮은 문제점이 있다.Since the concrete slab transmits the impact and noise of the upper layer to the lower layer as it is, it is necessary to block inter-layer noise.To block inter-layer noise, a noise-preventing material formed of a resin material is usually located between the concrete slab and the insulation material, but the noise is prevented. The ash has a low effect of blocking vibration and noise due to the pressure applied from the heat exchange pipe, cement and plastering layer located at the top.

또한, 일반적으로 단독주택, 빌라, 아파트와 같은 주거용 건축물의 벽체도 두께가 얇아 상,하부로 층간소음이 전달이 잘되고 이러한 층간소음을 제거하기에는 벽체의 두께를 두껍게 하여 층간소음 줄일수 있으나 그로 인한 제조단가와 전체적으로 벽체의 두께를 두껍게하면 실내의 공간면적이 감소를 향상시키게 하는 문제점과 작업시간이 증가시켜 작업성이 떨어지는 문제점이 있어 불편하였다.In addition, in general, the walls of residential buildings such as detached houses, villas, and apartments are thin, so inter-floor noise is well transmitted to the top and bottom. To remove such inter-floor noise, the thickness of the wall can be increased to reduce inter-floor noise. Increasing the unit cost and overall wall thickness has a problem of improving the reduction of the space area in the room and an increase in working time, which is inconvenient because of the problem of inferior workability.

따라서, 주거용 건축물의 실내 바닥의 콘크리트 슬라브를 통해 상,하부로 충격 및 층간소음을 그대로 하부로 전달하게 되는 문제점을 해결하는 층간소음을 방지하는 바닥구조를 선호하게 되었다.Therefore, a floor structure that prevents inter-floor noise, which solves the problem of transmitting impact and inter-floor noise to the lower part as it is through the concrete slab of the indoor floor of a residential building, has become preferred.
