Description
본 고안은 구조식 방음 및 흡음 보드에 관한 것으로서, 보다 상세하게는 일정한 틀에 폴리에스터섬유와 폴리우레탄 발포체를 가공하여 조립하는 구조식 방음 판넬에 관한 것이다.The present invention relates to a structural soundproofing and sound-absorbing board, and more particularly to a structural soundproofing panel assembled by processing polyester fibers and polyurethane foam in a certain frame.
일반적으로 실내의 방음재는 주로 폴리우레탄 또는 스티렌 등의 발포한 발포블럭이나 직접 분사하여 발포시키는 방식으로 방음시설을 설치하는 방법 이었다.In general, the soundproofing material in the room was a method of installing a soundproofing facility mainly by foaming blocks such as polyurethane or styrene or directly spraying.
상기의 종래의 방식은 장기간에 걸쳐 수분의 침투로 클랙과 부식의 작용이 원인이 있으며, 화재의 위험 또한 가지고 있으며, 화재시 유해가스의 발생으로 인한 치명적인 문제점을 수반되었으며, 방음성의 측면에 있어서도 음을 차단하는 효과는 있으나 음을 흡수하는 기능은 거의 없어 실내의 방음 및 흡음성에 대한 기능은 취약한 단점이 있다.The conventional method is caused by the infiltration of moisture over a long period of time due to the action of cracks and corrosion, and also has the risk of fire, accompanied by a fatal problem due to the generation of harmful gases in the fire, and also in terms of sound insulation There is an effect that blocks but there is almost no function of absorbing sound, the function of soundproofing and sound absorption in the room has a weak disadvantage.
그 외 유리솜 등을 이용하여 방음재의 재료로 이용되지만 유리솜과 같은 무기재료로 구성된 재료는 설치시 작업성의 애로와 환경적인 문제를 유발하여 사용하기에 적합하지 않다.In addition, glass wool is used as a soundproof material, but a material composed of an inorganic material such as glass wool is not suitable for use because it causes workability and environmental problems during installation.
이에 본 고안에서는 폴리에스터섬유가 가지고 있는 다공성의 특성을 이용해 방음 및 흡음성의 효과를 주었다.Therefore, the present invention gave the soundproofing and sound-absorbing effect by using the porous property of polyester fiber.
상기와 같은 종래의 문제점을 해결하기 위해 실내의 방음 및 흡음성을 높일 수 있는 폴리에스터섬유를 이용하여 음을 차단하고 흡수하는 역할을 하는데 그 목적이 있다.In order to solve the conventional problems as described above, the purpose is to block and absorb sound by using a polyester fiber that can increase the sound insulation and sound absorption of the room.
또한, 폴리에스터섬유의 혼용밀도를 이용하여 다양한 밀도차이에 의해 방음 및 흡음성의 효과를 증대시키는데 그 목적이 있다.In addition, the purpose is to increase the sound-absorbing and sound-absorbing effect by various density differences using the mixed density of the polyester fiber.

도시된 바와 같이 본 고안에 따른 구조식 방음 및 흡음 판넬(1)은 양쪽 측면에 공간을 가진 목재틀(2)에 있어서, 상기 목재틀(2)에 밀도 200-300K의 폴리에스터섬유에 35-55mm의 구멍을 가진 유공판(3)과, 상기 유공판(3) 후면에 밀도 20-30K의 폴리우레탄 발포체로 이루어진 보강재(4)를 접착하고, 상기 보강재(4) 후면에 20-25mm의 공기층(5)을 남겨두고, 상기 공기층(5) 후면에 밀도 20-30K의 폴리에스터섬유로 이루어진 기지재(6)로 구성되어지며, 사용되는 폴리에스터섬유는 방향성이 없는 랜덤형 섬유조직을 가진 섬유들을 사용하였다.As shown, the structural sound insulation and sound absorbing panel 1 according to the present invention is a wooden frame 2 having spaces on both sides, wherein the wooden frame 2 is 35-55 mm in polyester fiber having a density of 200-300 K. Bonding the hole plate (3) having a hole of and the reinforcing material (4) made of polyurethane foam having a density of 20-30K on the back of the hole plate (3), and the air layer of 20-25mm 5) leaving the air layer 5 on the back of the base material 6 consisting of polyester fibers having a density of 20-30K, and the polyester fibers used are fibers having a random fiber structure with no orientation. Used.
도 2는 본 고안의 구조식 방음 및 흡음 판넬의 사시도로서로서 목재틀(2)을 사용함에 있어서 금속판과는 달리 약간의 흡음성을 가진 목재틀을 사용하였다.Figure 2 is a perspective view of the structural sound insulation and sound absorbing panel of the present invention in the use of a wooden frame (2), unlike a metal plate used a wooden frame with a slight sound absorption.
또한, 밀도 20-30K의 폴리에스터섬유에 35-55mm의 구멍을 가진 유공판(3)에 있어서, 상기 유공판(3)의 구멍 간격은 100-150mm로 가공을 한다.Further, in the hole plate 3 having a hole of 35-55 mm in a polyester fiber having a density of 20-30 K, the hole gap of the hole plate 3 is processed to 100-150 mm.
상기 유공판에 구멍을 낸 이유는 소리를 모아주어 내부로 보내기 위해서이다.The hole in the perforated plate is for collecting sound and sending it inside.
또한, 밀도 20-30K의 폴리우레탄 발포체로 이루어진 보강재(4)를 사용함으로서 저주파의 소리까지 음을 흡수하기 위해서이다.In addition, by using the reinforcing material 4 made of a polyurethane foam having a density of 20-30K, the sound is absorbed up to low frequency sound.
상기와 같은 방법에 의해 고안된 구조식 방음 및 흡음 판넬(1)의 잔향실법에 의한 흡음율 시험결과를 하기의 표 1에 서술하였다.Sound absorption rate test results by the reverberation chamber method of the structural sound insulation and sound absorption panel (1) devised by the above method are described in Table 1 below.
상기 표-1에 나타난 값과 같이 63Hz의 저주파수일 때 잔향실법 흡음율이 0.40의 값을 나타냄으로서 저주파수의 음까지도 흡음을 할 수 있다는 것이며 또한, 주파수 300Hz일때 흡음율은 거의 모든 음을 흡수하는 수치를 나타내었으며, 고주파로 갈수록 80%이상의 음을 흡수하는 특성을 가지는 것으로 나타내었다.As shown in Table-1, the reverberation chamber sound absorption rate is 0.40 at the low frequency of 63 Hz, so that the sound can be absorbed even at the low frequency. In addition, it is shown that it has a characteristic of absorbing more than 80% of the sound at higher frequencies.
상기에서 서술한 바와 같이 본 고안은 구조식 방음 및 흡음 판넬에 관한 것으로서, 폴리에스터섬유의 다공적인 특성을 이용하여 음을 흡수하여 흡음율을 높이는 효과를 가져온다.As described above, the present invention relates to a structural soundproofing and a sound absorbing panel, which utilizes the porous properties of polyester fibers to absorb sound and thereby increase the sound absorption rate.
또한, 목재를 사용함으로써 실내의 디자인의 미려함과 자연친화적인 온화함을 준다.In addition, the use of wood gives the interior a beautiful and gentle nature.
