본 고안은 소음·진동 흡수용 흡음판의 구조에 관한 것으로, 상세하게는 밀도가 작은 오픈 셀(Open Cell) 구조의 폴리에칠렌 발포제(Polyethylene Foam)의 상하면에 다수의 구멍이 규칙적으로 배열천공된 밀도가 크고 두께가 얇은 폴리에칠렌 시트를 열융착 수단으로 복합적층시켜 극장, 방송실, 컴퓨터실, 공장이나 발전소등에서 발생하는 소음을 현저하게 줄여서 소음공해를 방지하고자 한 흡음판의 구조에 관한 것이다.The present invention relates to a structure of a sound absorbing plate for absorbing noise and vibration. In detail, a plurality of holes are regularly arranged on the upper and lower surfaces of a polyethylene foam having a small open cell structure, and have a high density. The present invention relates to a structure of a sound absorbing plate intended to prevent noise pollution by remarkably reducing the noise generated in a theater, a broadcasting room, a computer room, a factory, a power plant, etc. by stacking a thin polyethylene sheet with a heat fusion means.
종래의 흡음판은 소음을 단순히 차단만하는 단일판 또는 반사판으로 구성되어 있어서 판에 부딪치는 소음은 투과현상 및 반사현상이 발생되어 이로 인해 작업자는 물론 인근주변에 소음공해 피해를 주는 동시에 청각장등 직업병의 원인이 되는 문제점이 발생되었다.The conventional sound absorbing plate is composed of a single plate or a reflecting plate that merely blocks the noise, so the noise hitting the plate generates a transmission phenomenon and a reflection phenomenon, which causes noise pollution damage not only to the worker but also to the surrounding area. A problem that caused the problem occurred.
이러한 소음을 분석하여 보면 저주파음에서 고주파음에 이르기까지 많은 주파수를 형성하고 있는 것으로 고주파음은 파장이 짧기 때문에 밀도가 큰 재질이라 하여도 반사되지 못하고 투과하여 외부로 소음이 방출되는 것이며, 또 소음방지를 위하여 단일재질로 하여 두께를 두껍게 하거나 다수겹으로 복합구성하였다고 하여도 그 밀도가 동일하기 때문에 고주파음이나 저주파음을 현저하게 차단시키거나 흡수할 수 없게 된다.When analyzing these noises, many frequencies are formed from low frequency sound to high frequency sound. Since high frequency sound has a short wavelength, even a material with a high density is transmitted without being reflected, and noise is emitted to the outside. For prevention, even if the thickness is made of a single material thick or complex composition of multiple layers, the density is the same, it is not possible to significantly block or absorb high frequency or low frequency sound.
즉, 판에 소음이 입사하여 굴곡현상이 발생하고 굴곡파의 진폭은 입사파의 진폭과 같은 정도로 심하게 진동하는 일종의 공진상태가 되어 차음 성능이 저하되는 것이다.That is, noise enters the plate, causing a bending phenomenon, and the amplitude of the bending wave becomes a kind of resonance state vibrating to the same extent as the amplitude of the incident wave.
본 고안은 상기한 종래의 제반 문제점을 해결하기 위한 것으로 밀도와 두께가 다른 폴리에칠렌 발포체를 다수겹으로 복합적층시켜 소음 및 진동을 동시에 흡수토록 한 흡음판의 구조를 제공함에 그 목적이 있는 것이다.The present invention is to solve the above-mentioned problems in the prior art to provide a structure of a sound absorbing plate to absorb the noise and vibration at the same time by stacking multiple layers of polystyrene foam of different density and thickness.
이하, 본 고안의 구성을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the configuration of the present invention in detail with reference to the accompanying drawings as follows.
제1도 및 제2도는 본 고안 흡음판의 구조를 보인 일부사시도와 그 단면구성도로서, 밀도가 작은 오픈 셀 구조의 폴리에칠렌 발포체로 된 제2흡음층(1)의 상하면에 다수의 구멍(2)이 규칙적으로 배열천공된 밀도가 크고 두께가 얇은 폴리에칠렌 시트로 된 제1흡음층(3)과 제3흡음층(3')을 열융착 수단으로 복합적층하여 흡음판(4)을 구성한다.1 and 2 are a partial perspective view showing the structure of the sound absorbing plate of the present invention and a cross-sectional configuration thereof, wherein a plurality of holes 2 are formed on the upper and lower surfaces of the second sound absorbing layer 1 made of a polyethylene foam having a small density of open cell structure. The sound-absorbing plate 4 is constructed by laminating the regularly arranged first sound-absorbing layer 3 and the third sound-absorbing layer 3 'made of a thick, thin polyethylene sheet by heat fusion means.
위와 같이 구성된 본 고안은 공장이나 발전소 등지에서 발생한 고주파 및 저주파의 소음이 흡음판(4)의 제1흡음층(3)을 통과하면서 1차로 흡수 소멸되고 제1흡음층(3)의 구멍(2)을 통해 통과한 소음은 제2흡음층(1)을 통과하게 되므로 다시 그 소음을 2차로 흡수하여 소멸시키게 되고 제2흡음층(1)을 통과한 소음은 다시 제3흡음층(3')을 통과하면서 흡수되어 3차로 흡수 소멸시키게 된다.According to the present invention configured as described above, the high frequency and low frequency noise generated in a factory or a power plant or the like passes through the first sound absorbing layer 3 of the sound absorbing plate 4 and is first absorbed and extinguished, and the hole 2 of the first sound absorbing layer 3 is provided. Since the noise passed through the second sound absorbing layer 1 passes through the second sound absorbing layer 2 again, the noise is extinguished and the sound passing through the second sound absorbing layer 1 again passes through the third sound absorbing layer 3 '. As it passes through, it is absorbed and extinguished in the third order.
이때 흡수되는 소음은 파장이 짧은 고주파가 주로 흡수되어 소멸되고 저주파도 일부 흡수 소멸하게 되는 것인바, 즉 제1흡음층(3), 제3흡음층(3')과 제2흡음층(1)은 그 두께와 밀도가 상호 다르기 때문에 고주파 및 저주파의 소음을 3차에 걸쳐서 흡수 소멸시킬 수 있는 것이고, 상기한 바의 밀도가 다른 흡음층은 다공질의 기포 흠합체로 음을 차단 또는 기포내 공기진동 및 기포막 진동에 의한 굉음(강한 쇳소리 등) 흡수역할을 하게 되는 것이며, 제1흡음층(3), 제3흡음층(3')의 표면에 형성된 구멍(2)은 소음을 통과시키는 역할을 함과 동시에 흡음판(4)상에 내·외장판재(미도시됨)를 접합시 그 접합성을 향상시키는 역할을 하는 것이다.In this case, the absorbed noise is mainly absorbed and extinguished by a high frequency of short wavelengths, that is, some of the low frequencies are also absorbed and extinguished. That is, the first sound absorbing layer 3, the third sound absorbing layer 3 ′, and the second sound absorbing layer 1 are removed. Since the thickness and density are different from each other, the high-frequency and low-frequency noise can be absorbed and extinguished in three orders. The sound-absorbing layer having different densities is a porous bubble assembly, which blocks sound or vibrates in air bubbles. And absorbing the roar (strong beeping sound) due to the vibration of the bubble membrane, and the holes 2 formed on the surfaces of the first and third sound absorbing layers 3 and 3 'serve to pass noise. At the same time, when bonding the interior and exterior plate material (not shown) on the sound absorbing plate 4, it serves to improve the bonding property.
이상과 같은 본 고안은 공장이나 발전소의 내부에서 발생되는 소음과 설비가동으로 인한 소음, 진동 등 각종 소음·진동으로 인한 피해와 생산성 저하를 개선할 수 있어 매우 유용한 고안인 것이며, 특히 주거지역내에서의 효과는 더욱 특출한 것이고 극장이나 방송실, 컴퓨터실 등의 흡음판으로 적용하면 그 효과가 더욱 지대한 것이다.The present invention as described above is a very useful design that can improve the damage caused by various noises and vibrations such as noise generated from inside of a plant or a power plant and facility operation, vibration, and decrease in productivity, especially in a residential area. The effect of the is more exceptional, and when applied to the sound absorbing plate of the theater, broadcasting room, computer room, etc., the effect is even greater.
