Description
종래의 흡음식 방음판재는 금속케이스내에 유리면·암면과 같은 흡음재를 촉진시킨 것이 소개되고 있다.Background Art [0002] In the conventional sound absorbing soundproofing plate material, a sound absorbing material such as glass wool or rock wool is promoted in a metal case.
이와 같은 구성은 시간이 지남에 따라 흠음재는 자체하중과 도로의 진동에 의해 금속케이스내부에서 하부로 가라앉아 상부에 공간이 생기게 되고, 이때, 흡음재는 노후되면서 파손되어 금속케이스 내에서의 흡음재 분포상태가 고르지 못하여 방음효과가 초기설치상태보다 현저하게 떨어지는 문제점이 있었다.In this configuration, over time, the flammable material sinks from the inside of the metal case to the bottom due to its own load and the vibration of the road, resulting in a space at the top. There was a problem that the sound insulation effect is significantly lower than the initial installation state because it is uneven.
또 다른 문제로는 흡음재인 유리면과 암면은 공해물질이므로 노화에 의해 파손된 가루가 바람이 불편 흡음공을 통해 외부로 방출되어 공해문제를 유발할 우려가 있었다.Another problem is that glass wool and rock wool, which are sound absorbing materials, are pollutants, and thus, the powders damaged by aging may be released to the outside through uncomfortable sound absorbing holes, causing pollution problems.
이상과 같은 종래의 흡음식 방음판재는 금속케이스내의 흡음구조가 변형되지 않고 그 재질은 공해물질이 아닌 재질로 구성되어야 할 필요가 있다.In the conventional sound absorbing and insulating soundproofing plate material as described above, the sound absorbing structure in the metal case is not deformed and its material needs to be made of a material that is not a pollutant.
본 고안에서는 상기 요건을 충족시키기 위하여 흠읍재를 공해성이 없고, 다공질이면서 완충성이 양호한 스폰지 또는 우레탄 방포 시트를 사용하되 이를 공기층과 함께 다층구조로 구성하여 흡음성이 양호하고, 공해성이 없는 흡음식 방음판재를 구성한 것이다.In order to satisfy the above requirements, the present invention uses a sponge or urethane antifoam sheet having no pollution and a porous and good buffering material, but it is composed of a multilayer structure with an air layer to have good sound absorption and no pollution. It is composed of food soundproofing board.

내부에 흡음수단이 구비되도록 2쪽의 금속판(11)(12)을 결합하여 표면에는 흡음공(13)이 다수구비되고, 양측에 연결부(14)가 구비된 흡음판넬(10)을 구성함에 있어서, 상기 흡음수단은 각각의 금속판(11)(12)내면에 다공질이면서 완충성이 있는 스폰지 또는 우레탄 방포시트와 같은 합성수지제 다공질 흡음재(20)(21)를 각각 접착하고, 금속판(11)(12)을 결합시에는 상기 합성수지제 다공질시트(20)(21)사이에 매질이 다른 공기층(30)이 형성되도록 간격을 두어 3층의 흡음구조로 구성함을 특징으로 한 것이다.In combining the two metal plates 11 and 12 so that the sound absorbing means is provided therein, the surface has a plurality of sound absorbing holes 13, and the sound absorbing panel 10 having the connecting portions 14 at both sides is provided. The sound absorbing means bonds the porous sound absorbing material 20, 21 made of synthetic resin, such as a sponge or a urethane foam sheet, which is porous and buffered to the inner surface of each of the metal plates 11, 12, and the metal plates 11, 12, respectively. At the time of the combination, the porous sheets 20 and 21 of the synthetic resin are configured to have a three-layer sound absorbing structure at intervals such that an air layer 30 having a different medium is formed.
이상과 같은 본 고안 방음판재는 소음이 많이 발생하는 도로변이나 공장의 벽판재로 사용된다.The soundproof plate material of the present invention as described above is used as a wall plate of a roadside or a factory where noise is generated a lot.
이상과 같은 본 고안 흡음판넬(10)은 그 표면에 흡음공(13)으로 흡인된 소음은 다공질이면서 완충성이 있는 합성수지제 다공질 흡음재(20)에 흡음되어 음파를 약화시킨 다음 이를 통과한 음파는 매질이 다른 공기층(30)을 통과하면서 급속히 약화된 후 재차 그 후방의 흡음재(21)에서 흡읍되면서 거의 소멸되어 방음효과가 높아지는 효과가 있다.The sound absorbing panel 10 of the present invention as described above absorbs the sound absorbed by the sound absorbing hole 13 on the surface thereof and is absorbed by the porous sound absorbing material 20 made of synthetic resin which is porous and buffered. The medium is rapidly weakened while passing through the other air layer 30, and is absorbed by the sound absorbing material 21 at the rear thereof, and almost disappears to increase the sound insulation effect.
다른 효과로는 흡음재(20)(21)의 재질이 다공질 합성수지재이므로 공해성이 없고 사용도중 노화되어도 금속케이스내에서 하부로 주저앉거나 하는 변형이 없어 최초의 방음효과를 장기간 지속할 수 있는 효과가 있다.Another effect is that the sound-absorbing material 20, 21 is a porous synthetic resin material, so there is no pollution and there is no deformation that falls down in the metal casing even if it ages during use, so that the first soundproofing effect can be sustained for a long time. There is.
또 다른 효과로는 흡음재(20)와 흡음재(21) 사이의 공기층(30)에서 열전달을 차단하므로 단열효과가 향상되는 효과가 있다.Another effect is to block heat transfer in the air layer 30 between the sound absorbing material 20 and the sound absorbing material 21 has an effect that the heat insulating effect is improved.
본 고안은 흡음식 방음판재에 관한 것으로 특히 흡수되는 소음을 3단계로 약화시켜 방음효과를 증대시키는 것과, 단열효과를 갖도록 하는 것을 목적으로 한다.The present invention relates to a sound-absorbing soundproof plate material, and in particular, aims to increase the sound insulation effect by attenuating the absorbed noise in three stages, and to have an insulation effect.
