Description
본 발명은 아파트와 같은 공동주택의 바닥충격음 차음구조에 관한 것으로서, 더욱 상세하게는 바닥구조에 폴리에스테르 100% 을 이용한 흡음재를 사용함으로써 바닥충격음 흡음효과를 향상시키고 아울러 인체에 무해한 환경친화적인 환경을 제공하는 공동주택의 바닥충격음 차음구조에 관한 것이다.The present invention relates to a soundproofing structure of floor impact sound in a multi-family house such as an apartment, and more particularly, by using a sound absorbing material using 100% polyester in the floor structure to improve the sound absorbing effect of floor impact sound and to create an environment-friendly environment that is harmless to the human body. The floor impact sound insulation structure of a multi-unit housing provided.
바닥충격음은 아파트와 같은 공동주택의 상층바닥에서 사람의 보행, 물건의 낙하 등의 충격이 가해질 때 바닥 슬래브, 천장 또는 벽체를 통하여 하층 세대내로 방사되는 음이다.Floor impact sound is a sound radiated into a lower generation through floor slabs, ceilings or walls when an impact such as a person's walking or an object falls on the upper floor of a multi-family house such as an apartment.
일반적으로 콘크리트 슬래브 구조는 공기 전파음을 잘 차단하기 때문에 좋은 차음재라 할 수 있으나, 콘크리트구조에 충격이나 진동을 직접 가하게 되면 고체전파음으로 변하여 거의 감쇠되지 않고 인접한 다른 세대로 전달되어 음(소음)으로 방사되는 특성을 가지고 있다.In general, the concrete slab structure is a good sound insulation material because it blocks air propagation well, but if it directly impacts or vibrates the concrete structure, it becomes solid wave sound and is hardly attenuated and is transmitted to other adjacent generations. It has the property of being emitted to.
바닥충격음은 크게 그릇이나 골프공 등의 낙하음, 의자 이동음과 같이 고주파수 성분의 음을 많이 발생시키는 경량충격음과, 성인보행, 어린이들의 뜀뛰기 등과 같이 저주파수 성분의 음을 많이 발생시키는 중량충격음으로 구분하고 있다.Floor impact sound is divided into light impact sound that generates a lot of high frequency components such as falling sounds of bowls, golf balls, and chair movements, and heavy impact sound that generates a lot of low frequency components such as adult walking and children's skipping. Doing.
구미의 주택인 경우, 바닥충격음은 주로 사람이 구두를 신고 보행하는 소리, 즉 여성의 하이힐에 의한 충격음이 많이 발생하기 때문에 주로 경량충격음을 방지하는 구조로 되어야 하고, 한국이나 일본 주택의 경우에는, 생활습관이 좌식생활을 하기 때문에 상기 경량충격음외에 어린이의 뜀뛰기 등과 같은 중량충격음을 방지할수 있는 구조로 되어야 한다.In the case of houses in Europe and the United States, the floor shock sound is mainly designed to prevent light impact sound because the sound of people walking or walking, that is, a lot of impact sounds caused by women's high heels. Since the habit of living habits of sedentary life should be of a structure that can prevent a heavy impact sound, such as children skipping in addition to the light impact sound.
바닥충격음의 발생모델을 간단하게 나타내면 도 1과 같이 충격원, 바닥구조, 하부공간으로 구별할 수 있다.When the generation model of the floor impact sound is simply shown, it can be classified into an impact source, a floor structure, and a lower space as shown in FIG.
도 1에서 Mt는 충격원의 질량(㎏), Vt는 충격원의 충돌속도(m/s), kc는 충격면의 탄성계수(N/m2), rc는 충격면의 마찰저항계수(N/m/s), Ms는 바닥슬래브의 질량(㎏)이다. 여기서 Mt와 Ms는 고정되어 있으므로 kc와 rc를 조정하여 바닥충격음을 차단하여야 한다.In Figure 1, M t is the mass of the impact source (kg), V t is the impact speed of the impact source (m / s), k c is the elastic modulus of the impact surface (N / m 2 ), r c is friction of the impact surface The coefficient of resistance (N / m / s) and M s are the mass (kg) of the floor slab. Since M t and M s are fixed, k c and r c should be adjusted to block the floor shock sound.

이하 본 발명을 첨부도면을 참조하여 보다 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
본 발명의 공동주택의 바닥충격음 차음구조는 일반적인 공동주택의 바닥구조, 즉 슬래브(1), 단열을 위한 경량기포콘크리트(3), 상기 경량기포콘크리트(3)위에 도포되며 난방배관이 설치되는 마감 모르타르(4), 그리고 상기 마감모르타르(4)위에 접착제에 의하여 접착되는 표면마감재(5)로 구성되는 바닥구조에 있어서, 상기 슬래브(1)와 경량기포콘크리트(3)의 사이, 또는 마감 모르타르(4)와 표면마감재(5)사이에 폴리에스테르 100%를 원료로 하여 형성된 흡음재가 구성된다.The floor shock sound insulation structure of the multi-unit house of the present invention is the floor structure of a general multi-unit house, that is, slab (1), lightweight foamed concrete for insulation (3), the finish is applied on the lightweight foamed concrete (3) and the heating pipe is installed In the bottom structure consisting of a mortar (4), and a surface finish material (5) bonded to the finishing mortar (4) by an adhesive, between the slab (1) and lightweight foamed concrete (3), or the finishing mortar ( Between 4) and the surface finish material 5, the sound absorption material formed from 100% of polyester as a raw material is comprised.
표면마감재(5)가 모노륨인 경우에는 흡음재를 상기 슬래브(1)와 경량기포콘크리트(3)의 사이에 구성하고 표면마감재(5)가 원목인 경우에는 흡음재를 마감 모르타르(4)와 표면마감재(5)사이에 구성하는 것이 차음효과가 향상된다는 점에서 바람직하다.In the case where the surface finish material 5 is monolium, a sound absorbing material is formed between the slab 1 and the lightweight foam concrete 3, and when the surface finish material 5 is solid wood, the sound absorbing material is finished mortar 4 and the surface finish material ( It is preferable to comprise between 5) the sound insulation effect improves.
본 발명의 차음구조에 사용되는 흡음재는 폴리에스테르 섬유를 카딩(carding)하여 열압착하여 형성하는데, 폴리에스테르 섬유의 종류 및 굵기가 저융점 폴리에스테르(LMP, Low Melting Polyester) 4데니아(de), 레귤러 폴리에스테르(Reg., Regular) 7데니아(de), 레귤러 폴리에스테르 3 데니아(de)의 것들을 카딩하는데 그 혼합율을 3.5 : 3 : 3.5의 비율로 하여 카딩한 후 열압착한다.The sound absorbing material used in the sound insulating structure of the present invention is formed by carding polyester fibers and thermocompression bonding, and the type and thickness of the polyester fibers are low melting point polyester (LMP, Low Melting Polyester) 4 denia (de), Regular polyester (Reg., Regular) Carding of 7 denia (de), regular polyester 3 denia (de), carded at a mixing ratio of 3.5: 3: 3.5 and then thermocompression bonding.
저융점 폴리에스테르(LMP)를 사용하는 이유는 섬유들이 서로 접착이 잘 되도록 하기 위한 것이다.The reason for using low melting polyester (LMP) is to ensure that the fibers adhere well to each other.
상기 카딩된 흡음재 웹을 열압착하는 조건은 온도 180 ∼ 195℃, 압력 2㎏/㎠ 이상, 가압시간 10 ∼ 15분으로 한다.The conditions for thermally compressing the carded sound absorbing material web are set at a temperature of 180 to 195 ° C., a pressure of 2 kg / cm 2 or more, and a pressurization time of 10 to 15 minutes.
상기와 같이 해서 형성된 흡음소재는 흡음율이 0.75 ∼ 0.80, 열전도율이 0.030 ∼ 0.039, 밀도가 10 ∼ 250㎏/㎥ 의 물성치를 갖는다. 밀도는 72 ㎏/㎥ 인 것이 바람직하다.The sound absorption material formed as mentioned above has the physical properties of sound absorption coefficient 0.75-0.80, thermal conductivity 0.030-0.039, and density 10-250 kg / m <3>. The density is preferably 72 kg / m 3.
종류 및 굵기가 다른 폴리에스테르 섬유, 즉 저융점 폴리에스테르 4 데니아, 레귤러 폴리에스테르 7 데니아, 레귤러 폴리에스테르 3 데니아의 혼합율에 따른 흡음소재의 흡음계수는 다음 표와 같이 측정되었다. 흡음소재의 밀도는 72 ㎏/㎥ 의 것을 사용하였다.The sound absorption coefficients of the sound absorbing materials according to the mixing ratio of polyester fibers having different types and thicknesses, that is, low melting polyester 4 denia, regular polyester 7 denia, and regular polyester 3 denia were measured as follows. The sound absorbing material had a density of 72 kg / m 3.
흡음계수는 KS F 2814의 측정방식에 의하여 측정하였다.Sound absorption coefficient was measured by the measuring method of KS F 2814.
상기 표에서 알수 있는 바와 같이 가는 섬유의 비율이 높을수록 흡음성능이 향상됨을 알 수 있다. 그러나 웹(WEB)을 형성할 때 가는 섬유의 비율이 높을수록 섬유를 카딩할 때 보푸라기형태의 넵(NEP)의 발생이 많아지므로 카딩작업이 용이한 수준인 3.5:3:3.5의 비율로 혼합하는 것이 바람직하다.As can be seen from the table, the higher the ratio of the finer fibers, the better the sound absorption performance. However, the higher the ratio of finer fibers when forming webs, the greater the occurrence of fluff-like NEPs when carding the fibers, so mixing at a ratio of 3.5: 3: 3.5, which makes carding easier, It is preferable.
그리고 흡음재에 색상을 제공하기 위하여 레귤러 폴리에스테르 7 데니아의 폴리에스테르 섬유는 검정색의 것을 20%, 백색의 것을 10% 혼합하는 것이 바람직하다.In order to provide a color to the sound absorbing material, it is preferable that the polyester fiber of regular polyester 7 denia is mixed with 20% of black and 10% of white.
그리고 상기 흡음소재의 상면에 방수코팅제를 접착하여서 최종적인 본 발명의 흡음재를 구성하는데, 방수코팅제는 폴리프로필렌(poly propylene) 필름, 폴리 에틸렌(poly ethylene) 필름, 폴리에스테르(polyester) 필름, 폴리 비닐 클로라이드(poly vinyl chloride) 필름, 폴리 비닐 프로라이드(poly vinyl floride) 필름, 폴리 이미드(poly Imide) 필름 등의 재료를 이용할 수 있다.And by adhering the waterproof coating to the upper surface of the sound-absorbing material to form a final sound-absorbing material of the present invention, the waterproof coating agent is a polypropylene (poly propylene) film, polyethylene (polyethylene) film, polyester (polyester) film, polyvinyl Materials, such as a chloride film, a poly vinyl floride film, and a poly imide film, can be used.
