Description

단열 성능을 구비한 슬래브 일체형 층간소음 저감구조{Insulated Slab-Integrated Interlayer Noise Reduction Structure}Insulated Slab-Integrated Interlayer Noise Reduction Structure

본 발명은 공동주택의 바닥 충격음 방지 시스템에 관한 것으로써, 중량충격음에서 문제가 되는 저주파 충격음에 특히 효과적이면서 단열 성능을 구비한 슬래브 일체형 층간소음 저감구조에 관한 것이다.The present invention relates to a floor impact sound prevention system for an apartment house, and to a slab-integrated interfloor noise reduction structure that is particularly effective against low-frequency impact sound, which is a problem in heavy impact sound, and has thermal insulation performance.

도 1은 공동주택에서 종래의 뜬바닥 완충구조의 바닥구조를 도시한 단면도이고,1 is a cross-sectional view showing the floor structure of a conventional floating floor buffer structure in an apartment house,

도 2는 공동주택에서 종래의 슬래브 일체형 바닥구조를 도시한 단면도이다.2 is a cross-sectional view showing a conventional slab-integrated floor structure in an apartment house.

우리나라의 공동주택에서는 온수를 이용한 바닥온돌이 필수적이기 때문에, 초기에는 슬래브 위에 자갈을 도포하고 그 위에 온수배관을 한 후 몰탈로 마감하는 축열식이 적용되었으나, 시공성 및 에너지 효율에서 축열 보다는 단열을 중요시하는 공법이 적용되었다. In Korea, since floor ondol using hot water is essential in apartment houses in Korea, the thermal storage method was applied in the beginning, where gravel was applied on the slab, hot water piping was installed on it, and then finished with mortar. technique was applied.

축열 보다는 단열을 중요시하는 공법은 도 1과 같이 구조체인 바닥슬래브(S) 위에 열이 아래로 방사되어 손실되는 것을 막기 위해 매트형식의 단열재(I)를 설치하고, 그 위에 온수의 원활한 순환을 위한 평탄화(self-leveling)가 가능하며 열전도율이 낮은 경량기포콘크리트(AC)를 타설하고, 그 위에 열원인 온수배관(HP)을 설치하고, 온수배관(HP) 상부에 생활하중과 충격에 견딜 수 있으며 열전도율이 낮아 빠르게 난방이 가능한 마감몰탈(M)로 마감하는 공법이다.In the method that places importance on insulation rather than heat storage, as shown in FIG. 1, a mat-type insulation material (I) is installed on the floor slab (S), which is a structure, to prevent heat loss from being radiated downward, It is possible to flatten (self-leveling) and pours lightweight aerated concrete (AC) with low thermal conductivity, installs a hot water pipe (HP) as a heat source on it, and can withstand daily loads and shocks on top of the hot water pipe (HP). It is a method of finishing with finishing mortar (M) that has low thermal conductivity and can be heated quickly.

그러나 강성이 높은 바닥슬래브(S)와 온수배관(HP)을 포함한 경량기포콘크리트(AC)와 마감몰탈(M)로 구성되는 온돌판 사이에 상대적으로 강성이 매우 낮은 단열재(I)가 배치된 상기의 구조에서는 온돌판에 가해지는 충격이 단열재(I)를 통하여 바닥슬래브(S)에 전달되면서 공진이 발생하여, 결과적으로 상부 층에서의 생활 소음이 하부 층에 전달되어 층간소음에 매우 열약한 구조가 되었다.However, between the floor slab (S) with high rigidity and the lightweight aerated concrete (AC) including the hot water pipe (HP) and the ondol plate composed of the finishing mortar (M), the insulation material (I) with relatively low rigidity is placed In the structure of the structure, resonance occurs as the impact applied to the ondol plate is transmitted to the floor slab (S) through the insulating material (I). became

더불어 1980년대 이후에는 주거형태가 아파트 등과 같은 공동주택이 중심이 되며 층간소음 분쟁이 빈번해지며 심지어는 살인사건도 벌어지는 등 사회적으로 큰 문제가 되고 있다. 이에 2004년부터 층간소음을 법으로 규제하며 상기 구조에서 단열재(I) 대신 탄성이 있는 완충재를 설치하도록 하고 있다.In addition, since the 1980s, the housing type has become a major social problem, such as apartment houses, etc., and frequent noise disputes between floors and even murders. Accordingly, since 2004, inter-floor noise has been regulated by law, and a cushioning material with elasticity is required to be installed instead of the insulating material (I) in the above structure.

상기 완충재는 완충기능과 함께 온돌의 열손실을 억제하기 위해 법으로 정해진 매우 높은 수준의 단열성능이 요구되기 때문에 소재가 제한되어, 압축하여 탄성을 부여한 스티로폼(EPS)이나 발포고무(EVA, ethylene-vinyl acetate copolymer) 등이 비용이 저렴하며 시공이 쉬운 장점으로 널리 사용되고 있다. The material is limited because the cushioning material requires a very high level of insulation performance prescribed by law to suppress the heat loss of the ondol along with the cushioning function. vinyl acetate copolymer) is widely used because of its low cost and easy construction.

그러나 상기 소재는 완충성능과 장기처짐이 상충되는 특성으로 충분한 완충성능 구현이 불가능하여, 의자를 끄는 것과 같은 가벼운 충격에 의한 중고주파수 성분의 경량충격음에는 효과적이나, 보행과 같은 무겁고 부드러운 충격에 의한 저주파 성분의 중량충격음에서는 공진발생으로 맨바닥보다도 나쁜 결과를 보이고 있는 등 근본적인 해결이 안 되고 있다.However, the material is not capable of realizing sufficient cushioning performance due to the conflicting characteristics of cushioning performance and long-term deflection, so it is effective for light impact sound of medium and high frequency components caused by light impact such as dragging a chair, but low frequency caused by heavy and soft impact such as walking In the case of the weight impact sound of the components, the fundamental solution has not been solved, such as showing a worse result than the bare floor due to resonance generation.

이에 대한 대안으로 중량충격음의 원인인 바닥판의 진동을 억제하기 위해 바닥판의 판강성을 높이는 방법으로, As an alternative to this, in order to suppress the vibration of the bottom plate, which is the cause of the heavy impact sound, it is a method of increasing the plate rigidity of the bottom plate,

도 2와 같이 바닥슬래브(S)위에 완충재 없이 단열이 되는 혼합콘크리트(MC)와 마감몰탈(M)을 직접 타설(혼합콘크리트-온수배관-마감모르타르 순으로)하여 바닥슬래브(S)와 일체화시켜 결과적으로 바닥판을 두껍게 함으로서 바닥판의 판강성을 높이는 방법이 제안되고 있다(등록특허 10-0391558, 10-1208957, 10-1539630).As shown in Fig. 2, the mixed concrete (MC) and finishing mortar (M), which are insulated without a cushioning material, are directly poured on the floor slab (S) (in the order of mixed concrete - hot water pipe - finishing mortar) and integrated with the floor slab (S). As a result, a method of increasing the plate rigidity of the bottom plate by thickening the bottom plate has been proposed (Registration Patent Nos. 10-0391558, 10-1208957, 10-1539630).

상기 기술은 단열소재로 폐우레탄폼이나 폐스티로폴을 분쇄한 것(PI)에 재료분리를 억제하는 혼화제를 첨부하여 시멘트와 혼합하여 단열이 가능한 혼합콘크리트(MC)를 적용하는 것으로, 혼화제의 제법 혹은 재료에 따라 기술이 구분되며, 비중이 다른 소재를 액체상태에서 교합하기 때문에 재료의 균일성 유지가 어렵고, 상대적으로 비중이 작은 단열소재가 외부의 충격 등으로 상부로 떠오르는 등 시공을 포함한 품질관리가 어려운 단점이 있다.The above technique is to apply mixed concrete (MC) that can be insulated by mixing with cement by adding an admixture that suppresses material separation to pulverized waste urethane foam or waste styropole (PI) as an insulating material. The technology is classified according to the material, and it is difficult to maintain the uniformity of the material because materials with different specific gravity are occluded in a liquid state. It has a difficult drawback.

등록특허 10-1539642는 등록특허 10-1539630에 차음과 단열을 개선하기 위해 혼합콘크리트(MC)와 마감몰탈(M) 사이에 띠 형태의 합성수지 필름이 서로 상하로 포개어져 결합용 사로 망 조직으로 보호한 면상 구조체로 이루어진 보강망을 추가한 것으로, 차음과 단열은 개선되나 보강망이 혼합콘크리트(MC)와 마감모탈(M)을 분리시켜 일체화가 되지 않으므로 바닥판의 판강성을 높이기 위한 본래의 목적에서 벗어나는 문제가 있다.Registered Patent 10-1539642 discloses that, in order to improve sound insulation and insulation in Patent Registration 10-1539630, a band-shaped synthetic resin film is superimposed on top of each other between the mixed concrete (MC) and the finishing mortar (M) to protect it with a mesh structure for bonding. By adding a reinforcing net made of a one-sided structure, sound insulation and heat insulation are improved, but the reinforcing net is not integrated by separating the mixed concrete (MC) and the finishing mortar (M). There is a problem of getting out of

이에 본 발명자는 단열매트와 경량기포콘크리트 등을 구조적으로 일체화하여 판강성을 증가시키므로 상부에서 발생하는 진동을 억제하고 단열성을 확보하는 것을 특징으로 하는 단열 성능을 구비한 슬래브 일체형 층간소음 저감구조를 개발하기에 이르렀다.Accordingly, the inventors of the present inventors have developed a slab-integrated inter-floor noise reduction structure with thermal insulation performance, characterized in that the insulating mat and lightweight foam concrete are structurally integrated to increase the plate rigidity, thereby suppressing vibrations generated from the upper part and securing thermal insulation properties. came to
