Description

터널용 방음장치{ Soundproof device for tunnel }Soundproof device for tunnel}

본 고안은 방음장치에 관한 것으로, 특히 지하도나 터널의 벽면에 설치되는 터널용 방음장치에 관한 것이다.The present invention relates to a soundproofing device, and more particularly to a soundproofing device for a tunnel that is installed on the wall of the underpass or tunnel.

일반적으로, 방음장치는 소리가 전달되는 것을 방지하는 장치로, 특히 도로의 가장자리를 따라 설치되는 방음벽은 차량에서 발생하는 소음이 도로 주변으로 전달되지 않도록 소리의 일부를 흡수하고 일부를 반사하여 소리가 방음벽을 통과하지 못하도록 된 것이다.In general, sound insulation is a device that prevents sound from being transmitted. In particular, a soundproof wall installed along the edge of a road absorbs part of the sound and reflects the part so that the noise generated by the vehicle is not transmitted to the vicinity of the road. It is not allowed to pass through the soundproof walls.

외부에 노출된 도로와는 달리, 터널이나 지하도에서는 차량에서 발생하는 소음의 일부가 반사되더라도 운전자는 소음을 크게 느끼게 되는데, 종래에 터널이나 지하도에 설치되는 방음장치는 차량의 소음을 일부 흡수하고 상당부분을 다시 운전자에게 반사시켜 운전자에게 큰 효과를 거두지 못하고 있는 실정이다.Unlike roads exposed to the outside, in the tunnel or underpass, the driver feels the noise even if some of the noise generated by the vehicle is reflected. Conventionally, the soundproofing device installed in the tunnel or the underpass absorbs some of the vehicle's noise. The part is reflected back to the driver, which does not have a great effect on the driver.

또한, 종래의 방음벽과 같은 것은 지면 위에 설치되므로 방음벽을 지면에 고정시키기 위한 토목공사가 수반되어야 하는 번거로움이 있을 뿐만 아니라, 설치작업에 많은 시간과 인력이 소모되는 문제점이 있었다.In addition, since the conventional soundproof wall is installed on the ground, it is not only hassle that a civil engineering work is required to fix the soundproof wall to the ground, but also has a problem that a lot of time and manpower are consumed in the installation work.

특히, 차량의 통행량이 많은 지역이나 터널내와 같은 좁은 장소에서는 방음벽을 설치하는데 장시간을 소요할 경우 교통에 많은 불편을 주게 되는 문제점이 있었다.In particular, in a narrow place such as an area with a large amount of traffic of a vehicle or in a tunnel, there is a problem in that it takes a lot of inconvenience to traffic when it takes a long time to install the sound barrier.

이에 본 고안은 상기한 바의 제반 문제점들을 해소하기 위해 안출된 것으로, 차량에서 발생하는 소음을 회절시켜 간섭으로 소거되게 하므로써 터널 통과시 소음공해를 줄일 수 있게 되고 단시간에 간편하게 설치될 수 있어 설치작업시 통행에 불편을 최소화할 수 있도록 된 터널용 방음장치를 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve all the problems described above, and by diffracting the noise generated in the vehicle to be eliminated by interference, it is possible to reduce the noise pollution when passing through the tunnel and to be easily installed in a short time. It is an object of the present invention to provide a soundproofing device for tunnels that can minimize inconvenience to city traffic.

상기한 바의 목적을 달성하기 위한 본 고안은, 상부에 소리회절부가 절곡형성된 'L'자형의 방음판이 구비되고, 상기 방음판의 일측에 흡음부재가 부착되며,상기 방음판이 벽면에 탈착가능하게 고정설치될 수 있도록 상기 방음판과 흡음부재가 끼워지는 삽입부가 형성된 한쌍의 고정브라켓이 구비된 구조이다.The present invention for achieving the above object is provided with a soundproof plate of the 'L' shaped bent sound diffraction portion on the upper portion, a sound absorbing member is attached to one side of the soundproof plate, the soundproof plate is fixed to the wall surface detachably It is a structure provided with a pair of fixing brackets formed with an insertion portion for the soundproof plate and the sound-absorbing member to be installed.

따라서, 상기 소리회절부를 통해 벽면에 반사되어 나오는 차량의 소리를 굴절시켜 소음이 차량의 운전자에게 반사되는 것을 줄일 수 있고, 상기 고정브라켓으로 흡음부재가 부착된 방음판을 간편하게 설치할 수 있게 되는 것이다.Therefore, the sound is refracted by the vehicle reflected on the wall through the sound diffraction to reduce the reflection of the noise to the driver of the vehicle, it is possible to easily install the soundproof plate attached to the sound absorbing member to the fixing bracket.

상기의 구조로 된 본 고안의 특징은 방음판(10)에 'L'자형의 소리회절부(11)가 형성된 것에 있는 바, 상기 소리회절부(11)는 지면과 수평하게 형성되어 방음판(10)에 반사되어 나오는 차량의 소리를 굴절시키므로써 소음이 차량의 운전자에게 반사되는 것을 줄일 수 있도록 된 것이다.The features of the present invention having the above structure is that the sound diffraction portion 11 of the 'L' shape is formed on the soundproof plate 10, the sound diffraction portion 11 is formed horizontally to the ground and the soundproof plate 10 By refracting the sound of the vehicle reflected by the reflected light to reduce the reflection of noise to the driver of the vehicle.

본 고안의 또 하나의 특징은 상기 방음판(10)이 끼워지는 삽입부(31)가 형성된 고정브라켓(30)이 구비된 것에 있는 바, 상기 고정브라켓(30)은 하부가 대략 'ㄷ'자 형상으로 절곡되어 삽입부(31)가 형성되어 그 삽입부(31)에 방음판(10)과 흡음부재(20)를 끼우므로써 간편하게 설치할 수 있도록 된 것이다.Another feature of the present invention is that the soundproof plate 10 is provided with a fixing bracket 30 is formed with an insertion portion 31 is fitted, the fixing bracket 30 is the bottom of the approximately 'c' shape The insertion part 31 is bent to form the soundproof plate 10 and the sound absorbing member 20 in the insertion part 31 so as to be easily installed.

상기 방음판(10)은 흡음부재(20)를 고정시키고 소리를 굴절시키는 역할을 하는 것으로, 두개의 사각판이 맞대어진 'L'자형으로 형성되어 소리회절부(11)가 지면과 수평하게 형성되고, 타측판에 흡음부재(20)가 부착되어 있다.The soundproof plate 10 serves to fix the sound absorbing member 20 and refract the sound, and two square plates are formed in an 'L' shape to which the sound diffusing plate 11 is formed to be horizontal to the ground, The sound absorbing member 20 is attached to the other side plate.

상기 소리회절부(11)는 소리를 지면쪽으로 굴절시키는 역할을 하는 것으로, 상기 방음판(10)의 일측에 지면과 수평하게 형성되어 흡음부재(20)가 부착된 면에 부딪혀 반사되는 소리를 아래쪽으로 굴절시키게 된다.The sound diffracting unit 11 serves to refract the sound toward the ground, and is formed horizontally on one side of the soundproof panel 10 to hit the surface on which the sound absorbing member 20 is attached and reflected downward. Will be refracted.

즉, 도 3에 도시된 바와 같이, 차량에서 벽면으로 전달되는 소리는 흡음부재(20)에 상당부분이 흡수되고, 흡수되지 않고 위쪽으로 반사되는 소리는 상기 소리회절부(11)에 부딪혀 아래쪽으로 굴절되므로써 벽면으로 전달되는 소리와 상쇄작용으로 음이 소거되는 현상이 발생하게 되는 것이다.That is, as shown in Figure 3, the sound transmitted to the wall surface in the vehicle is absorbed by the sound absorbing member 20, and the sound is not absorbed and reflected upwards hit the sound diffusing portion 11 downwards The sound is canceled by the refraction and the sound transmitted to the wall by refraction.

상기 흡음부재(20)는 차량에서 전달되는 소리를 흡수하는 역할을 하는 것으로, 통상의 흡음부재는 다공질이면서 두께가 두꺼울수록 흡음률이 커지고, 밀도에 비례하여 흡음률이 높아지지만 두께에 대한 의존도가 더 높으며, 유연성 재료일수록 표면층과 내부에서의 마찰손실이 원인이되어 음에너지의 감쇠효과가 크게 되는데, 본 고안의 흡음부재(20)는 다공질이면서 연성의 재질인 스폰지를 사용하여 흡음할 수 있도록 된 것이다.The sound absorbing member 20 serves to absorb the sound transmitted from the vehicle. In general, the sound absorbing member is porous, and the thicker the sound absorption rate is, the higher the sound absorption rate is in proportion to the density, but the higher the dependency on the thickness. In addition, the flexible material causes friction loss between the surface layer and the inside to increase the damping effect of the negative energy. The sound absorbing member 20 of the present invention is made to absorb sound using a sponge that is porous and soft.

상기 고정브라켓(30)은 상기 방음판(10)을 벽면에 고정시키는 역할을 하는것으로, 고정브라켓(30)과 방음판(10)을 결합시키는 삽입부(31)가 형성되고, 고정볼트(34)를 사용하여 고정브라켓(30)을 벽면에 고정시킬 수 있도록 상부에 다수개의 결합공(32)이 천공되어 있다.The fixing bracket 30 serves to fix the sound insulation plate 10 to a wall surface, and an insertion portion 31 for coupling the fixing bracket 30 to the soundproof plate 10 is formed, and the fixing bolt 34 is formed.
