Description

소음저감용 방음구조물{SOUNDPROOF STRUCTURE FOR NOISE REDUCTION}SOUNDPROOF STRUCTURE FOR NOISE REDUCTION}

본 발명은 소음저감용 방음구조물에 관한 것으로, 특히 도로상에 터널구조로 설치되고 차량의 운행시 발생하는 교통 소음을 흡음부재로 흡입하여 구조물의 외부로 배출되는 소음이 감소할 수 있도록 그 구조가 개량된 소음저감용 방음구조물에 관한 것이다.The present invention relates to a soundproof structure for noise reduction, in particular, the structure is installed in a tunnel structure on the road and the structure so that the noise emitted to the outside of the structure can be reduced by inhaling the traffic noise generated during the operation of the vehicle as a sound absorbing member. The present invention relates to an improved soundproof structure for noise reduction.

일반적으로, 고속도로나 고속화 도로를 운행하는 차량 등이 주변 주택 밀집지역 등을 통과하는 경우 진동과 소음으로 인하여 많은 문제가 야기될 것으로 예상되며 이를 사전에 예방하기 위해서는 방음시설에 대한 대책이 필수적이다.In general, when vehicles running on highways or high-speed roads pass through dense neighborhoods, many problems are expected to occur due to vibration and noise, and measures for soundproofing facilities are necessary to prevent them in advance.

특히, 도시철도나 도심 고속화 도로의 경우에는, 주택 밀집지역을 통과하는 경우가 많음에도 도로에서 주거지역까지의 거리가 멀지 않아 소음공해로 인한 민원이 점점 증가하고 있는 실정이다.In particular, in the case of urban railways or urbanized high-speed roads, complaints due to noise pollution are increasing because the distance from the road to the residential area is not far from many, even though they pass through dense housing areas.

이러한 민원에 대비하기 위해서나 혹은 환경기준에 맞추기 위해 도심의 고층 빌딩지역이나 고층 아파트 단지를 통과하는 고가도로 등에 방음시설로서 방음벽 또는 방음터널 등을 적용하고 있다.In order to prepare for such complaints or to meet environmental standards, soundproof walls or soundproof tunnels are used as soundproofing facilities in urban areas such as high-rise buildings and overpasses passing through high-rise apartment complexes.

그러나, 고층아파트 주변에 설치된 방음벽의 경우 효과적인 방음을 하기 위 해서는 그 높이가 매우 증가하여야 하므로 이에 따른 풍하중의 영향으로 높이를 제한할 수밖에 없는 실정이다.However, in the case of soundproof walls installed around high-rise apartments, the height of the soundproof walls must be increased so that the height can not be limited due to the influence of the wind load.

따라서 방음벽이 갖는 구조적인 문제점을 보완하기 위한 보다 효과적인 소음대책으로서 방음터널이 널리 사용되고 있다.Therefore, soundproof tunnels are widely used as a more effective noise countermeasure to compensate for structural problems of soundproof walls.

그러나, 종래기술에 따른 방음터널은 통상적으로 상부가 폐쇄된 구조를 채택하고 있기 때문에 차량의 운행시 발생하는 소음을 차단할 수는 있었으나, 터널 내부에서 발생되는 분진 등의 배출이 곤란하였고, 차량의 터널 주행시 터널 소음이 증가하는 문제점이 있었다. 또한 화재 발생시 연기의 배출이 곤란한 문제점이 야기되었던 것이다.However, since the soundproof tunnel according to the prior art generally adopts a structure in which the upper part is closed, it is possible to block noise generated when the vehicle is running, but it is difficult to discharge dust generated inside the tunnel, There was a problem that the tunnel noise increases during driving. In addition, the fire was a problem that was difficult to discharge the smoke.

본 발명은 상기와 같은 종래기술의 문제점을 해소하기 위하여 안출한 것으로, 본 발명의 목적은 차량의 운행시 발생하는 교통 소음을 흡음부재로 흡입하여 구조물의 외부로 배출되는 소음이 감소할 수 있도록 그 구조가 개량된 소음저감용 방음구조물을 제공하는 데 있다.The present invention has been made in order to solve the problems of the prior art as described above, the object of the present invention is to suck the traffic noise generated during the operation of the vehicle with a sound absorbing member so that the noise emitted to the outside of the structure can be reduced The present invention provides an improved soundproof structure for noise reduction.

방음구조물(10)은 도 2에 도시된 바와 같이 그 상부에 소음을 배출하도록 다수의 개구공(12)이 형성되어 있다. 개구공(12)은 방음구조물(10)의 상부에 구비되는 보강프레임(14)에 의해 구획되도록 형성되어 있다. 이때, 보강프레임(14)은 개구공(12)의 입구와 출구가 동일하도록 방음구조물(10)의 상부에 수직으로 배치되고 그 상부와 개구공(12)을 향하는 양 내측면이 개구되도록 형성된다.As shown in FIG. 2, the soundproof structure 10 has a plurality of opening holes 12 formed thereon to discharge noise. The opening hole 12 is formed to be partitioned by the reinforcing frame 14 provided on the soundproof structure 10. At this time, the reinforcement frame 14 is disposed so as to be perpendicular to the upper portion of the soundproof structure 10 so that the inlet and outlet of the opening hole 12 is the same, and both inner surfaces facing the upper portion and the opening hole 12 are formed. .

흡음부재(20)는 도 3에 도시된 바와 같이 방음구조물(10)의 개구공(12)으로 배출되는 소음을 흡수하는 역할을 하며, 이를 위해서 소음을 흡수하기 위한 흡음재(22)와 이 흡음재(22)를 감싸도록 형성되는 하우징(24)으로 구성되어 보강프레임(14)의 내부에 설치되어 있다.The sound absorbing member 20 serves to absorb the noise discharged to the opening hole 12 of the soundproof structure 10, as shown in FIG. 3, and for this purpose, the sound absorbing material 22 and the sound absorbing material ( 22 is formed in the housing 24 is formed to surround the reinforcement frame (14).

이때, 흡음부재(20)는 양 측단의 모서리부가 서로 접하도록 보강프레임(14)에 설치된다. 이는 방음구조물(10)의 개구공(12)을 통과하여 배출되는 소음이 흡음부재(20)의 양 측단 모서리부로 배출되는 것을 방지하기 위함이다.At this time, the sound absorbing member 20 is installed on the reinforcing frame 14 so that the corner portions of both side ends. This is to prevent the noise emitted through the opening 12 of the soundproof structure 10 from being discharged to both side edges of the sound absorbing member 20.

흡음재(22)는 소리를 잘 흡수하는 재료, 예컨대 텍스, 유리 섬유, 펠트, 폴리우레탄 폼 등으로 구성되는 것이 바람직하나, 굳이 이에 한정하지는 아니한다.Sound absorbing material 22 is preferably made of a material that absorbs sound well, such as tex, glass fiber, felt, polyurethane foam, but is not limited thereto.

하우징(24)은 개구공(12)의 내측면을 향하는 양 측면에 다수의 흡음공(26)이 구비되어 있다. 흡음공(26)은 개구공(12)으로 배출되는 소음의 음파가 들어가 흡음재(22)로 흡수되어 다시 되돌아 나오지 못하게 한다.The housing 24 is provided with a plurality of sound absorbing holes 26 on both sides facing the inner surface of the opening hole 12. Sound absorbing hole 26 is a sound wave of the noise discharged to the opening hole 12 is absorbed into the sound absorbing material 22 to prevent it from coming back.

이러한 흡음부재(20)는 방음구조물(10)로부터 배출되는 소음이 감소할 수 있도록 개구공(12)을 통과하는 소음을 흡수하는 구조로 된 것이다.The sound absorbing member 20 is configured to absorb the noise passing through the opening hole 12 so that the noise emitted from the soundproof structure 10 can be reduced.

이러한 구성을 갖는 본 발명의 작용을 설명하면 다음과 같다.The operation of the present invention having such a configuration will now be described.

본 발명의 제 1 실시 예에 따른 소음저감용 방음구조물은, 도 4에 도시된 바와 같이 방음구조물(10)의 내부를 통과하는 차량으로부터 발생된 소음은 구조물(10)의 내부로 전파되고, 전파된 소음은 구조물(10)의 상부에 형성된 개구공(12)을 통해 외부로 배출되면서 개구공(12)의 내측면에 구비된 흡음부재(20)에 의해 흡수되게 된다.In the noise reduction soundproof structure according to the first embodiment of the present invention, as shown in FIG. 4, noise generated from the vehicle passing through the soundproof structure 10 is propagated into the structure 10 and propagates. The noise is discharged to the outside through the opening hole 12 formed in the upper portion of the structure 10 is absorbed by the sound absorbing member 20 provided on the inner surface of the opening hole 12.

즉, 소음은 개구공(12)을 통과시 반사 및 굴절되면서 저감되도록 그 일부가 흡음부재(20)의 하우징(24)에 구비된 다수의 흡음공(26)으로 들어가 흡음재(22)로 흡수되게 된다.That is, a part of the sound is absorbed by the sound absorbing material 22 by entering a plurality of sound absorbing holes 26 provided in the housing 24 of the sound absorbing member 20 so that the noise is reflected and refracted when passing through the opening hole 12. do.

이때, 흡음부재(20)는 양 측단의 모서리부가 서로 접하도록 보강프레임(14)에 설치됨으로써, 방음구조물(10)의 개구공(12)을 통과하여 배출되는 소음이 흡음부재(20)의 양 측단 모서리부로 배출되는 것을 방지하기 위함이다.At this time, the sound absorbing member 20 is installed in the reinforcing frame 14 so that the corner portions of both side ends are in contact with each other, the noise discharged through the opening hole 12 of the soundproof structure 10, the amount of the sound absorbing member 20 This is to prevent the discharge to the side edges.

따라서 방음구조물(10)은 그 내부에서 발생하여 개구공(12)으로 배출되는 소음을 흡음부재(20)에 의해 흡수함으로써 주택가로 전달되는 소음을 최소화할 수 있는 것이다.Therefore, the soundproof structure 10 may minimize the noise transmitted to the residential area by absorbing the noise generated in the inside and discharged to the opening hole 12 by the sound absorbing member 20.
