Description

방음벽용 소음감쇠기{Noise reducer for soundproof wall}Noise reducer for soundproof wall

본 발명은 방음벽에 상단에 설치되는 소음감쇠기에 관한 것으로, 특히 흡음과 회절소음 감쇠기능을 극대화할 수 있고, 방음벽의 상단 마감재, 조명수단, 안전주행유도수단, 방음벽의 외관개선수단 등으로 활용할 수 있는 새로운 형태의 방음벽용 소음감쇠기에 관한 것이다.
The present invention relates to a noise attenuator installed at the top of the soundproof wall, in particular, can maximize the sound absorption and diffraction noise attenuation function, can be utilized as the top finish of the soundproof wall, lighting means, safety driving guide means, appearance improvement means of the soundproof wall, and the like. To a new type of sound damper for sound barriers.

소음의 전파를 차단하기 위해 설치한 벽을 방음벽이라 한다. 이는 주로 소음의 차단이 목적이기 때문에 소음이 발생하는 위치에서 그 소음을 듣는 사람이 있는 장소 사이에 설치하며, 도로 옆에 설치하는 도로 방음벽 등이 대표적이다. 소리는 파동의 형태로 전달되기 때문에 파동의 전파특성을 고려해서 방음벽을 제작하게 되며, 때문에 높이를 높게 만들거나 두께를 두껍게 만드는 것이 일반적이다. 또한 음파를 흡수할 수 있는 특수한 재료를 사용해서 제작하기도 한다.
Walls installed to block the propagation of noise are called soundproof walls. This is mainly because the purpose of blocking the noise is installed between the place where the noise is heard from the location where the noise occurs, the road soundproof wall is installed next to the road is typical. Since sound is transmitted in the form of waves, soundproof walls are manufactured in consideration of the propagation characteristics of waves. Therefore, it is common to make the height high or make the thickness thick. It is also manufactured using special materials that can absorb sound waves.

방음벽은 소음을 받는 위치인 수음점을 고려해서 제작하며, 제작시에는 음을 얼마나 흡수할 수 있느냐 하는 흡음률, 벽을 통과한 소음이 얼마나 줄어드느냐 하는 투과손실, 방음벽 설치 이후에 소음 수치가 감소하는 정도를 고려해서 제작한다. 우리나라에서는 환경부에서 고시한 기준에 따라 방음벽을 제작, 설치하며 여기에는 위와 같은 기능적인 측면뿐만 아니라 미관, 안전 측면도 고려하도록 되어 있다. The soundproof wall is manufactured considering the sound absorbing point, which is the location where the noise is received, and the sound absorption rate of how much sound can be absorbed during production, the transmission loss of how much the noise passing through the wall is reduced, and the noise level decreases after the soundproof wall is installed. Consider the degree of production. In Korea, sound barriers are manufactured and installed in accordance with the standards announced by the Ministry of Environment. In addition to the above functional aspects, the aesthetics and safety aspects are to be considered.

음원과 수음점 사이에 방음벽이 없는 경우, 소리는 소음원으로부터 수음점에 직접적인 경로로 전달된다. 그러나 음원과 수음점 사이에 방음벽이 있는 경우에는 소음원으로부터 발생한 소음은 방음벽의 상단을 회절하여 수음점에 도달하며 그 과정에서 소음이 감소한다. 이런 회절 감쇠에 의한 방음벽의 감음 효과는 경로차와 해당 음의 주파수(파장)에 의하여 결정된다.
If there is no sound barrier between the sound source and the sound collection point, the sound is transmitted from the noise source directly to the sound collection point. However, if there is a sound barrier between the sound source and the sound absorbing point, the noise from the noise source diffracts the top of the sound barrier to reach the sound absorbing point and the noise decreases in the process. The attenuation effect of the sound barrier by such diffraction attenuation is determined by the path difference and the frequency (wavelength) of the sound.

이러한 목적의 방음벽은 H형 지주 사이에 차음판이나 흡음재가 부착된 차음판(혹은 흡음재 내장의 차음판)을 쑥 들어가게 세워 설치한 것이 일반적이고, 그 소음 저감 효과는 방음벽의 높이에 따라 결정되기 때문에, 효과를 향상시키기 위해서는 벽의 높이를 높게 할 필요가 있었다. 그러나, 방음벽의 높이를 높게 하면, 비용 상승이 되는데다가, 일조, 경관, 통풍 혹은 전파 장해 등 부적합한 문제가 생기는 경우도 있었다.
The soundproof wall for this purpose is generally installed by placing a soundproof plate or soundproof plate (or soundproof plate with sound absorbing material built-in) between H type pillars, and the noise reduction effect is determined by the height of the soundproof wall. In order to improve the effect, it was necessary to raise the height of the wall. However, if the height of the soundproof walls is increased, the cost increases, and there are cases where unsuitable problems such as sunshine, landscape, ventilation, or radio wave interference may occur.

그래서, 방음벽의 상단부에 흡음용의 관통공이 다수개 형성된 금속제 타공판 커버부재로 원통형 또는 V자형 흡음재를 커버한 소음감쇠기를 수평으로 설치하여 방음벽의 높이를 그만큼 높게 하지 않고 소음 저감 효과(방음 효과)를 향상시키는 방안이 제안되어 있다.
Therefore, a metal perforated plate cover member having a plurality of sound absorbing through-holes formed at the upper end of the soundproof wall is installed horizontally with a noise attenuator covering a cylindrical or V-shaped sound absorbing material, so that the height of the soundproof wall is not so high. Improvement measures have been proposed.

그러나, 원통형 흡음재의 경우, 소음 저감 효과를 늘리기 위해서 대형화하는 것이 비용이나 강도, 구조면에서 곤란하며, 또한 V자형의 벽의 경우는 소음 저감 효과를 늘리기 위해서는 그 치수를 크게 하지 않으면 안되고, 비용 상승이 되는 것이나, 설치후의 풍압 강도의 문제가 있었다. 특히, 커버부재로 사용되는 금속제 타공판은 타공율이 50% 정도밖에 되지 않아 타공되지 않은 금속표면에 부딪히는 소음은 회절 및 반사되어 감쇠기의 효율을 떨어뜨리는 문제도 있다.
However, in the case of the cylindrical sound absorbing material, it is difficult to increase the size to increase the noise reduction effect in terms of cost, strength, and structure, and in the case of the V-shaped wall, the size must be increased to increase the noise reduction effect. There was a problem of this, and the wind pressure strength after installation. In particular, since the metal perforated plate used as the cover member has only a porosity of about 50%, noise hitting the unperforated metal surface is diffracted and reflected, thereby lowering the efficiency of the attenuator.

따라서 본 발명은 포획된 소음을 흠음 및 회절방지 소멸 등에 의한 소음감쇠기능을 극대화시킬 수 있는 방음벽용 소음감쇠기를 제공하는 것을 목적으로 한다. Therefore, an object of the present invention is to provide a noise damper for noise barriers capable of maximizing noise attenuation by trapped noise and anti-diffraction extinction.

The noise attenuator according to the present invention is installed horizontally along the soundproof wall on the top of the soundproof wall including a plurality of struts and soundproof plates vertically spaced at predetermined intervals to absorb noise and prevent diffraction sounds. The soundproof wall has various types of soundproof walls, such as a transparent soundproof wall, a soundproof soundproof wall, a reflective soundproof wall, and a soundproof soundproof wall. The noise attenuator of the present invention provides an effect of effectively improving the soundproof function even when applied to any soundproof wall.

도 1 내지 11에 도시되는 바와 같이 본 발명에 따르는 소음감쇠기(10)는 소음포집부재(11), 흡음부재(12) 및 커버부재(13)를 구비한다.
As shown in FIGS. 1 to 11, the noise damper 10 according to the present invention includes a noise collecting member 11, a sound absorbing member 12, and a cover member 13.

소음포집부재(11)는 소음원 쪽으로 예를 들어 ‘ㄱ’자형 단면형태로 절곡되거나 또는 ‘C’자형 단면형태로 만곡되고 소음원쪽으로 개방되어서 개방부쪽으로 직접 들어오거나 또는 방음벽을 따라 회절하면서 들어오는 소음을 포집하는 작용을 한다. 소음포집부재(11)의 재질은 금속, 합성수지, 목재 등을 이용할 수 있으며, 그 중에서도 특히 바람직한 것은 성형이 용이하고 부식에 강하면서 경량인 금속이며, 그 대표적인 예로는 알루미늄이 있다.
The noise collecting member 11 may be bent toward the noise source, for example, in the shape of 'A' shape or bent in the shape of 'C' shape and open toward the noise source to directly enter the opening or diffract along the soundproof wall. It works by collecting. The material of the noise collecting member 11 may be a metal, a synthetic resin, wood, etc. Among them, a particularly preferable one is a metal which is easy to mold, resistant to corrosion and lightweight, and a representative example thereof is aluminum.

이러한 소음포집부재(11)는 그 하부가 결합부(11-1)가 되어 도 5에 잘 나타난 바와 같이 방음벽의 상단에 결합되어서 방음벽의 상단 마감재로서도 기능한다. 또한 소음포집부재(11)의 단부(11-2)는 폐쇄하여 포집된 소음이 감쇄기 외부로 빠져나가는 것을 방지하는 것이 바람직하다. 또한 소음포집부재(11)의 내부에도 소정간격으로 칸막이를 둘 수도 있다.
The noise collecting member 11 is coupled to the upper end of the soundproof wall as shown in Figure 5, the lower portion of the coupling portion (11-1) also serves as the top finish of the soundproof wall. In addition, the end portion 11-2 of the noise collecting member 11 is preferably closed to prevent the collected noise from escaping out of the attenuator. In addition, a partition may be placed inside the noise collecting member 11 at a predetermined interval.

소음포집부재(11) 내부에 부착되는 흡음부재(12)는 소음포집부재(11)의 내벽에 대응하는 형상으로 되어 소음포집부재(11)의 내부에 부착되며 흠음성 재질로 이루어져 소음을 흡수하는 기능이 있으며 이에 더하여 전면, 즉 노출된 면에 요철이 형성되어 포집된 회절음을 감쇠하는 기능을 한다.
The sound absorbing member 12 attached to the noise collecting member 11 has a shape corresponding to the inner wall of the noise collecting member 11, and is attached to the inside of the noise collecting member 11 and made of a flaw material to absorb noise. In addition to this, irregularities are formed on the front surface, that is, the exposed surface, and thus attenuate the collected diffraction sounds.

흡음부재의 요철은 랜덤하게 형성하는 것이 바람직하며, 이와 같이 랜덤하게 하면 경로차에 의해 회절소음이 크게 감쇠되는 효과를 얻을 수 있다.
The irregularities of the sound absorbing member are preferably formed randomly. When the randomness is made in this way, the diffraction noise is greatly attenuated by the path difference.

커버부재(13)는 흡음부재(12)를 상기 소음포집부재(11)에 밀착시킴과 동시에 커버하기 위한 것으로, 본 발명에서는 커버부재로서 와이어, 파이프, 바 및 메쉬망으로 이루어진 군에서 선택되는 1 또는 2 이상을 사용한다. 커버부재(13)로서 도시된 제1 실시예에서는 커버부재로서 메쉬망을 사용하고 있고, 제 2 실시예에서는 와이어, 파이프 또는 바와 같은 줄형태의 커버재를 사용하고 있으며, 제3 실시예에서는 메쉬망으로 되는 제1 커버(13-1)와 줄형태의 커버재로 되는 제2 커버(13-2)를 병용한 것이다.
Cover member 13 is to cover the sound absorbing member 12 to the noise collecting member 11 at the same time to cover, in the present invention is selected from the group consisting of a wire, pipe, bar and mesh net as a cover member. Or 2 or more. In the first embodiment shown as the cover member 13, a mesh net is used as the cover member. In the second embodiment, a cover member in the form of a wire, pipe or bar is used. In the third embodiment, the mesh is used. It uses together the 1st cover 13-1 which becomes a net, and the 2nd cover 13-2 which becomes a cover material of a string form.

이러한 커버부재(13)는 흡음부재(12)를 소음포집부재(11)에 견고하게 내장 견지함과 동시에 흠음부재(12)의 노출을 극대화시켜서 포집되는 소음이 반사되고 회절하는 것을 극소화시키는 작용을 한다.
The cover member 13 firmly holds the sound absorbing member 12 in the noise collecting member 11 and maximizes the exposure of the defect member 12 to minimize the reflection and diffraction of the collected noise. do.

텐션조절이 가능한 커버부재를 사용하는 경우에는 감쇠기의 양단이나 경간 부위에 커버재의 텐션을 조절할 수 있는 텐션수단을 두어서 흡음부재의 밀착을 조절할 수 있도록 하는 것이 바람직하다. 제한하기 위한 것은 아니지만, 이러한 텐션수단의 예로는 터버클 등이 있다.
When using a cover member capable of adjusting the tension, it is preferable to provide tension means for adjusting the tension of the cover member at both ends or the span of the damper so as to adjust the adhesion of the sound absorbing member.
