Description

소음 방지용 흡음판{.}Sound-absorbing plate for noise prevention {.}

본 발명은 소음 방지용 흡음판에 대한 것으로서, 보다 상세하게는 기초 지반 위에 일정간격으로 수직 형성되는 다수의 지주프레임에 각각 배치되어 벽체를 구성함으로써 소음을 반사 및 흡수하는 흡음판에 관한 것이다. The present invention relates to a sound absorbing plate for preventing noise, and more particularly, to a sound absorbing plate reflecting and absorbing noise by constituting a wall disposed in a plurality of strut frames vertically formed at regular intervals on a foundation ground.

일반적으로 도로 주변은 차량 통행으로 인한 소음이 매우 심해 도로면이나 그 인접지역에 거주하는 사람들은 심한 소음공해에 시달리게 된다. In general, the noise around roads is very high, and people living in or adjacent to the road face severe noise pollution.

또한, 대형 공장등의 주변도 마찬가지로 공장가동에 따른 소음피해의 대상이 되고 있다. 이에 따라 주거지역에 인접한 도로가나 공장의 담장 등에는 도 1에 도시된 바와 같이 인접지역으로 소음을 차단하기 위한 흡음벽체(W)가 설치되는 추세이다. In addition, the surroundings of large factories, etc. are similarly subjected to noise damage caused by the plant operation. Accordingly, the sound absorbing wall (W) for blocking the noise to the adjacent area as shown in Figure 1 tends to be installed in the road or the fence of the factory adjacent to the residential area.

이러한 흡음벽체(W)는 기초 콘크리트(C) 상에 다수의 지주프레임(S)을 앵커볼트(Ancker bolt:B)에 의해 일정 간격으로 배열 고정하고, 인접하는 두 지주프레임(S)의 대향하는 채널(Channel)들에 소음을 흡수하는 복수의 흡음판(1)을 각각 적 층한 뒤, 그 상단을 연결 플레이트로 고정함으로써 구성된다. The sound absorbing wall (W) is fixed to a plurality of strut frames (S) arranged on the foundation concrete (C) at a predetermined interval by an anchor bolt (Ancker bolt: B), which is opposed to the adjacent two strut frames (S) It is configured by laminating a plurality of sound absorbing plates 1 each absorbing noise in the channels, and then fixing the upper end thereof with a connecting plate.

따라서, 흡음벽체(W)가 우수한 방음효율을 갖기 위해서는 흡음판(1)의 흡음성능이 우수하지 않으면 안된다. Therefore, in order for the sound absorption wall W to have the outstanding sound insulation efficiency, the sound absorption performance of the sound absorption board 1 must be excellent.

도 2에는 이러한 종래의 흡음판(1)의 일예를 도시하였다. 이것은 소정형태, 즉 슬롯(slot) 타입의 흡음구(3)를 다수 가지는 전면판넬(2)의 후방에 후면판넬(4)을 일정간격으로 접합하고, 이들 전면판넬(2)과 후면판넬(4)이 이루는 내부공간(6)에 글래스 울(Glass wool) 등의 흡음부재(7)를 수용하고 있다. 2 shows an example of such a conventional sound absorbing plate 1. This joins the rear panel 4 at a predetermined interval to the rear of the front panel 2 having a plurality of sound absorbing holes 3 of a predetermined type, that is, slot type, and the front panel 2 and the rear panel 4 In the inner space (6) is made of a sound-absorbing member (7), such as glass wool (Glass wool).

그리고 후면판넬(4)에 흡음부재(7)의 후면을 접촉 지지하는 지지돌기(5)를 내측으로 밴딩(bending) 형성하여 후면판넬(4)과 흡음부재(7)에 사이에 공기층(8)을 형성하고 있다. 이에 따라 공기중의 음파가 전면판넬(2)의 흡음구(3)를 통해 흡음판(1)의 내부로 유입된 뒤, 1차적으로 흡음부재(7)에 흡수되어 감쇄됨과 함께 이 흡음부재(7)를 투과한 음파가 2차적으로 후속하는 공기층(8) 및 후면판넬(4)에 의해 공명(共鳴)됨으로써 소음을 차단하게 된다.The back panel 4 is formed by bending a support protrusion 5 for contacting and supporting the rear surface of the sound absorbing member 7 to the inside to form an air layer 8 between the back panel 4 and the sound absorbing member 7. To form. Accordingly, the sound waves in the air are introduced into the sound absorbing plate 1 through the sound absorbing port 3 of the front panel 2, and are primarily absorbed and attenuated by the sound absorbing member 7 and the sound absorbing member 7 The sound wave transmitted through) is resonated by the air layer 8 and the rear panel 4 which are subsequently followed to block the noise.

그런데 이러한 종래의 흡음판(1)은 내측으로 유입되어 흡음부재(7)를 투과한 음파의 일부만이 차폐되고, 대부분의 음파는 도 2에 점선의 화살표로 도시한 바와 같이 후면판넬(4)을 투과하여 후방으로 전달되게 된다. 즉 흡음부재(7)를 통과한 음파의 일부만이 후면판넬(4)에서 반사되어 흡음부재(7)로 재진입할 뿐 대부분의 음파는 그대로 후면판넬(4)을 투과하게 된다. By the way, such a conventional sound absorbing plate 1 is shielded only a part of the sound waves that are introduced into the inside and transmitted through the sound absorbing member 7, most of the sound waves are transmitted through the rear panel 4 as shown by the dotted arrows in FIG. Will be delivered to the rear. That is, only a part of the sound waves passing through the sound absorbing member 7 is reflected from the rear panel 4 and re-enters the sound absorbing member 7, and most of the sound waves pass through the rear panel 4 as it is.

따라서 도로변 등에 흡음벽체(W)를 설치하더라도 어느 정도의 소음은 감수할 수 밖에 없다. 한편 이러한 문제를 해결하기 위한 수단으로 흡음부재(7)의 두께를 증가시켜 흠음율을 높이는 방안이 강구될 수 있는데, 이 경우 흡음판(1)의 두께가 커져 취급과 시공이 번잡해지고 설치비용이 상승할 뿐만 아니라 효율적으로 소음을 차단할 수 없는 문제점이 있다. Therefore, even if the sound absorbing wall (W) is installed on the side of the road, some noise is bound to be reduced. On the other hand, as a means for solving this problem, a method of increasing the flaw rate by increasing the thickness of the sound absorbing member 7 may be devised. In this case, the thickness of the sound absorbing plate 1 is increased, which makes the handling and construction complicated and the installation cost increases. Not only that, there is a problem that can not effectively block the noise.

본 발명은 상술한 문제점을 해결하기 위한 것으로서, 흡음부재의 두께를 증가시키지 않으면서도 소음의 흡음율을 향상시킬 수 있으며, 이에 따라 후방으로 투과되는 음파의 투과율을 낮출 수 있어 소음을 효과적으로 제거하기 위한 소음 방지용 흡음판을 제공함에 그 목적이 있다.
