본 발명은 층간 소음 저감 구조체에 관한 것으로, 보다 구체적으로는 다층 건축물의 위층에서 나는 소음의 아래층으로의 전달을 최소화할 수 있는 층간 소음 저감 구조체에 관한 것이다.The present invention relates to an interlayer noise reduction structure, and more particularly, to an interlayer noise reduction structure capable of minimizing the transmission of noise from an upper floor of a multi-story building.

일반적으로 다층 건축물의 층간 바닥 구조를 살펴보면, 콘크리트 슬라브 위에 기초 콘크리트를 구축하고, 그 상부에 난방 배관 및 마감 모르타르를 타설한 후 그 위에 장판 등의 바닥 마감재를 설치한다.In general, when looking at the interlayer floor structure of a multi-storey building, the foundation concrete is built on the concrete slab, the heating pipes and finishing mortar is poured on the upper part, and then floor coverings such as floor coverings are installed thereon.

그런데 이러한 종래의 다층 건축물의 층간 바닥 구조는 상층에서 발생된 충격 소음이 곧바로 하층에 전달됨으로 인해 하층 거주자에게 정신적인 스트레스와 노이로제를 발생시켜 입주민들 간의 마찰을 일으키는 주요 원인이 되는 문제점이 있었다. 따라서 바닥의 콘크리트 슬라브에 층간 소음을 저감시키기 위한 저감재를 매설하는 방안이 제시되었다.By the way, the floor structure of the conventional multi-layered building has a problem that the main noise causing the stress between the residents in the lower floor residents due to the impact noise generated in the upper floor immediately transmitted to the lower floor causing friction between residents. Therefore, a method of embedding a reducing material to reduce the inter-layer noise in the concrete slab of the floor has been proposed.

As shown, the interlayer noise reduction structure 50 embedded between the concrete slab 10 and the foamed concrete 20 and the finishing mortar 30 is formed with an unevenness 53a at an upper portion thereof and at regular intervals at a lower portion thereof. After the air layer 53b is formed and the high-density layer 53 made of a synthetic rubber vibration damping sheet is provided, the medium-density layer composed of a cross-linked polyethylene (PE; Polyethylene) foam at the bottom or the top and bottom of the high-density layer 53 ( 52) and a low density layer 51 composed of an uncrosslinked PE foam is thermocompressed to form a multilayer structure.

도 3에 도시된 바와 같이, 본 발명의 실시예에 따른 층간 소음 저감 구조체(100)는 흡음단열재(110)와; 상기 흡음단열재(110)의 하부에 배치되는 보강재보드(120)와; 상기 보강재보드(120)의 하면에 배치되며, 내측에 액체가 채워진 상부액체부재(130)와; 콘크리트 슬라브의 상면에 배치되며, 내측에 액체가 채워진 하부액체부재(140); 및 상기 상부액체부재(130)와 하부액체부재(140)를 서로 이격되도록 지지하는 하나 이상의 스틸기둥(150)을 포함한다.As shown in Figure 3, the interlayer noise reduction structure 100 according to an embodiment of the present invention and the sound absorbing insulation (110); A reinforcement board 120 disposed below the sound absorbing insulation 110; An upper liquid member 130 disposed on a lower surface of the reinforcement board 120 and filled with a liquid inside; A lower liquid member 140 disposed on an upper surface of the concrete slab and filled with a liquid therein; And at least one steel pillar 150 supporting the upper liquid member 130 and the lower liquid member 140 to be spaced apart from each other.

상기 흡음단열재(110)는 건축물의 에너지 절감을 위해 필수적으로 사용되는 소재로 단열의 효과만이 아니라 건축물 외부로부터 유입되는 소음과 건물 내에서 발생하는 각종 소음을 차단하여 쾌적한 실내 환경을 확보하기 위한 흡음재로서의 특성도 보유하여야 한다. 이 흡음단열재(110)는 소재 자체의 열전도율이 작은 것이 단열효율이 좋으나, 대부분 단열재의 소재 자체는 열전도율이 그다지 작지 않기 때문에, 보통의 경우 단열재의 열전도율을 감소시키기 위하여 다공질이 되도록 제조함으로써 단열재 내부에 형성된 기공 속에 있는 공기의 단열성이 함께 이용될 수 있도록 단열재가 제조되고 있다. 또한, 흡음재로는 천이나 음향 타일 같이 부드럽고 다공질인 것이 적합하다. The sound absorbing insulation 110 is a material used to reduce the energy of the building as a sound absorbing material to ensure a pleasant indoor environment by blocking not only the effect of heat insulation but also various noises generated inside the building and noise. It should also have characteristics as The sound absorbing heat insulating material 110 has a good thermal insulation efficiency because the material itself has a low thermal conductivity, but since most of the material itself is not very small, the thermal conductivity is usually manufactured to be porous in order to reduce the thermal conductivity of the heat insulating material. Insulation materials have been manufactured so that the thermal insulation of air in the pores formed can be used together. As the sound absorbing material, a soft and porous material such as cloth or acoustic tile is suitable.

흡음단열재(110)로서는 주로 글라스 울을 사용하거나, 재활용이 가능하여 환경친화적이고 화재시 유독 가스의 발생이 거의 없는 폴레에틸렌테레프탈레이트(PET;Polyethylene-terephthalate)와 같은 열가소성 수지의 방사 화이버를 사용한다.As the sound absorbing heat insulating material 110, glass wool is mainly used, or a fiber made of thermoplastic resin such as polyethylene-terephthalate (PET) which is environmentally friendly because it is recyclable and hardly generates toxic gases in case of fire. .

상기 보강재보드(120)로는 폴리비닐클로라이드(PVC; Polyvinylchloride) 또는 폴리프로필렌(PP; Poly-propylene)과 같은 합성수지재를 사용할 수 있다.As the reinforcement board 120, a synthetic resin material such as polyvinyl chloride (PVC) or polypropylene (PP) may be used.

상기 상부액체부재(130)와 하부액체부재(140)의 내부에 채워지는 액체는 물에 한정되지 않고, 공업용 오일 등을 사용하는 것도 가능하다. 또한, 빙점이 -50℃ 이하인 부동액을 사용할 수도 있다.The liquid to be filled in the upper liquid member 130 and the lower liquid member 140 is not limited to water, it is also possible to use industrial oil and the like. In addition, an antifreeze liquid having a freezing point of -50 ° C or lower may be used.

상기 스틸기둥(150)으로 연결된 상부액체부재(130)와 하부액체부재(140)는 하나의 보강재보드(120)에 대하여 다수 개가 배치될 수 있으며, 이들 사이에는 액체 또는 고체로 채워지지 않는 공간이 형성되는 것이 바람직하다. 이로써 소음이 고체층을 통과한 이후에 고체층이 아닌 공기층 또는 최소한의 액체층을 통과하게 하여 소음의 소멸 효율을 증대시킬 수 있도록 하였다.The upper liquid member 130 and the lower liquid member 140 connected to the steel pillars 150 may be arranged in plural with respect to one reinforcement board 120, and a space not filled with liquid or solid between them is provided. It is preferably formed. This allows the noise to pass through the air layer or at least the liquid layer rather than the solid layer after passing through the solid layer to increase the extinction efficiency of the noise.

또한, 본 발명에 따른 층간 소음 저감 구조체(100)는 상기 하부액체부재(140)의 하면에 배치되는 흡음재(160)를 더 포함할 수 있다.In addition, the interlayer noise reduction structure 100 according to the present invention may further include a sound absorbing material 160 disposed on the lower surface of the lower liquid member 140.

상부액체부재(130)와 하부액체부재(140)는 합성수지나 합금 등으로 된 용기의 형태로 제조될 수 있다.The upper liquid member 130 and the lower liquid member 140 may be manufactured in the form of a container made of synthetic resin or alloy.

도시된 바와 같이, 상기 상부액체부재(130)와 상기 보강재보드(120)와의 사이에는 완충재(131)를 더 배치시켜 충격의 흡수를 한층 강화할 수 있다.As shown, the buffer member 131 may be further disposed between the upper liquid member 130 and the reinforcement board 120 to further enhance shock absorption.

또한, 상기 상부액체부재(130)와 하부액체부재(140)의 사이에 상기 스틸기둥(150)에 의하여 관통되도록 배치되는 약음 및 흡음 · 진동 완화부재(170)를 더 비치할 수도 있다.In addition, between the upper liquid member 130 and the lower liquid member 140 may be further provided with a weak sound, sound absorption, vibration damping member 170 disposed to penetrate by the steel pillar 150.

도 5는 본 발명의 층간 소음 저감 구조체를 적용하여 시공한 건축물 바닥의 단면도이다. 도시된 바와 같이, 본 발명의 층간 소음 저감 구조체(100)는 콘크리트 슬라브(200)의 상측에 배치되며, 그 상부로는 경량의 기초 콘크리트(300)가 올라가고, 난방관(410)이 매설된 후 마감 모르타르(400)가 타설된다. 그리고 최종적으로 장판 등의 바닥 마감재(500)가 깔리게 되는 것이다.5 is a cross-sectional view of the building floor constructed by applying the interlayer noise reduction structure of the present invention. As shown, the interlayer noise reduction structure 100 of the present invention is disposed on the upper side of the concrete slab 200, the upper part of the lightweight base concrete 300 is raised, the heating pipe 410 is embedded Finishing mortar 400 is poured. And finally the floor finishing material 500, such as jangpan will be laid.

즉, 다층 건축물의 상층에서 발생한 소음은 실내의 바닥 마감재(500)를 통하여 전달되기 시작하고, 마감 모르타르(400)와 기초 콘크리트(300)를 지나면서 서서 히 줄어든다. 음파의 전달 속도는 고체-액체-기체의 순서로 빠르다. 그러므로 음파는 고체에서 더욱 완전하고 손실되지 않은 형태로 전달이 된다. 따라서 윗층의 소음은 본 발명에 따른 층간 소음 저감 구조체(100)의 흡음단열재(110), 보강재보드(120), 완충재(131), 상부액체부재(130), 약음 및 흡음 · 진동 완화부재(170), 하부액체부재(140) 및 흡음재(160)를 거치면서 현저히 소멸되어 콘크리트 슬라브(200)에는 최소한의 소음만이 전달되게 되는 것이다.That is, the noise generated in the upper floor of the multi-storey building begins to be transmitted through the floor finishing material 500 in the room, and gradually decreases while passing through the finishing mortar 400 and the foundation concrete 300. The rate of sound delivery is fast in the order of solid-liquid-gas. Thus, sound waves are transmitted in a more complete and undamaged form in solids. Therefore, the noise of the upper layer is the sound absorbing insulation 110, the reinforcing board 120, the buffer member 131, the upper liquid member 130, weak sound and sound absorption and vibration damping member 170 of the interlayer noise reduction structure 100 according to the present invention. ), The lower liquid member 140 and the sound absorbing material 160 is remarkably extinguished so that only the minimum noise is transmitted to the concrete slab 200.

이상과 같이, 본 발명은 비록 한정된 실시예와 도면에 의해 설명되었으나, 본 발명은 이것에 의해 한정되지 않으며 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술 사상과 아래에 기재될 특허청구범위의 균등 범위 내에서 다양한 수정 및 변형이 가능함은 물론이다.As mentioned above, although this invention was demonstrated by the limited embodiment and drawing, this invention is not limited by this, The person of ordinary skill in the art to which this invention belongs, Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.

본 발명의 층간 소음 저감 구조체에 따르면, 내측에 액체가 포함된 액체부재를 적용하여 소음이 액체층과 공기층을 통과하게 함으로써 보다 빨리 소음을 저감할 수 있는 효과가 있다.According to the interlayer noise reduction structure of the present invention, by applying a liquid member containing a liquid inside the noise through the liquid layer and the air layer there is an effect that can reduce the noise more quickly.
