Description
본 고안은 차량 소음을 차단하는 방음벽을 구성하는 방음벽용 흡음판넬에 관한 것이다.The present invention relates to a sound absorbing panel for a soundproof wall that constitutes a soundproof wall that blocks vehicle noise.
방음벽의 흡음율 측정방법은 KSF 2805 에 의하여 공인된 시험검사기관에서 측정한 결과가 방음판의 시공직전 완제품 상태에서 다음의 흡음율의 평균의 70% 이상 되어야 한다.The method of measuring sound absorption of soundproof wall should be more than 70% of the average of the following sound absorption in the finished product just before construction of soundproof board.

도 1 및 도 2에 도시된 종래에 사용되던 방음벽용 흡음판넬(1)은 알루미늄판으로 제조되며 판넬의 두께(t)가 95 mm 이다. 판넬의 전면판(2)에는 다수개의 흡음구(3)가 배치되고 판넬 내부의 전방에는 흡음재(4)를 설치하여 구성된다.The sound absorbing panel 1 for the soundproof wall conventionally used shown in FIGS. 1 and 2 is made of an aluminum plate and the thickness t of the panel is 95 mm. A plurality of sound absorbing openings 3 are disposed on the front panel 2 of the panel, and a sound absorbing material 4 is installed in the front of the panel.
흡음재(4)는 후면판(5)에 형성된 돌출부(6)에 의해서 판넬의 내부에 지지된다. 그러나 이러한 차음벽은 흡음율이 평균 70% 이상일 뿐 상기 각각의 주파수에서 요구되는 흡음율을 만족시키지 못한다.The sound absorbing material 4 is supported inside the panel by the projections 6 formed on the back plate 5. However, such sound insulation walls do not satisfy the sound absorption rate required at the respective frequencies only when the sound absorption rate is on average 70% or more.
본 고안의 목적은 상기와 같은 종래의 단점을 해결하기 위하여 각각의 주파수에서 요구되는 흡음율을 만족시키는 방음벽용 흡음판넬을 제공하고자 하는 것이다.It is an object of the present invention to provide a sound absorbing panel for soundproof walls that satisfies the sound absorption rate required at each frequency in order to solve the above disadvantages.
본 고안의 방음벽용 흡음판넬은 두께가 200 mm 가 되고 흡음재는 밀도가 32 kg/cm3인 유리면을 사용하여 구성된다. 또한 판넬의 내부에서 흡음재를 지지하는 지지부는 개구를 지니는 형태로 형성된다.The sound absorbing panel for the soundproof wall of the present invention has a thickness of 200 mm and the sound absorbing material is composed of a glass surface having a density of 32 kg / cm 3 . In addition, the support portion for supporting the sound absorbing material in the panel is formed to have an opening.

본 고안을 첨부된 도면에 도시된 실시예를 참조하여 상세히 설명한다.The present invention will be described in detail with reference to the embodiments shown in the accompanying drawings.
도3 및 도4 에는 본 고안의 방음벽용 흡음판넬이 도시되는데, 전면판(10)에는 다수개의 흡음구(11)가 일정한 배열로 형성된다.3 and 4 shows a sound absorbing panel for the soundproof wall of the present invention, the front plate 10 is formed with a plurality of sound absorbing holes 11 in a constant arrangement.
도4에 도시되듯이, 전면판(10)의 후방에는 후면판(12)이 형성되며 도면에는 후면판(12)의 두께가 좌우로 연장되어 방음벽을 지지하는 H 비임사이에 설치된다. 이러한 형태는 기존의 H 비임의 크기에 맞추어 흡음판넬을 설치하기 위하여 전면판의 두께를 100 mm 로 하고 후면판의 두께를 100 mm 크기로 맞춘 것이다.As shown in FIG. 4, the rear plate 12 is formed at the rear of the front plate 10, and the thickness of the rear plate 12 extends from side to side to be installed between the H beams supporting the sound barrier. This type is to adjust the thickness of the front panel to 100 mm and the thickness of the rear panel to 100 mm in order to install the sound absorbing panel according to the size of the existing H beam.
이러한 흡음판넬의 형태와 달리 흡음판넬의 전면판과 후면판을 동일하게 연장하여 판넬의 두께를 200 mm 로 제작하여 이러한 크기의 판넬을 지지하는 H 비임사이에 설치할 수 도 있다.Unlike the shape of the sound absorbing panel, the front panel and the rear panel of the sound absorbing panel may be extended in the same manner to produce a panel thickness of 200 mm, and may be installed between the H beam supporting the panel of this size.
도5 에는 본 고안의 흡음판넬의 단면도가 도시되는데, 판넬의 전방에는 유리면으로 된 흡음재(13)가 설치된다.5 is a cross-sectional view of the sound absorbing panel of the present invention, in front of the panel is provided with a sound absorbing material 13 made of glass.
본 고안의 흡음재(13)는 두께(t)가 100 mm 이고 밀도가 32 kg/cm3이다.The sound absorbing material 13 of the present invention has a thickness t of 100 mm and a density of 32 kg / cm 3 .
흡음재(13)는 판넬의 내부에서 흡음재(13)와 후면판(12)사이의 공간에 상하로 설치되는 지지부(14)에 의해서 지지된다.The sound absorbing material 13 is supported by the support part 14 which is installed up and down in the space between the sound absorbing material 13 and the back plate 12 inside the panel.
도6 에는 본 고안의 흡음재 지지부(14)가 도시되는데, 흡음재 지지부(14)는 폴리우레탄 포옴으로 제조되며 지지부에는 다수개의 각진 개구(15)가 형성된다.6 shows a sound absorbing material support 14 of the present invention, the sound absorbing material support 14 is made of a polyurethane foam, the support is formed with a plurality of angled openings (15).
지지부(14)의 개구(15)들은 조립 후 소음이 판넬 내부를 돌아다니게 하여 흡음효과를 높히게 한다.The openings 15 of the support 14 allow noise to move around the panel after assembly to increase the sound absorption effect.
본 고안의 흡음재 지지부는 도6 에 도시된 것과는 달리 흡음재의 후방에 스틸 바아를 설치하여 흡음재를 판넬내부에서 지지하게 할 수 도 있다.The sound absorbing material support part of the present invention may be provided with a steel bar at the rear of the sound absorbing material, unlike that shown in FIG. 6, to support the sound absorbing material in the panel.
상기와 같이 구성된 본 고안의 흡음판넬의 흡음율을 실험한 결과 다음과 같은 표를 얻었다.As a result of experimenting the sound absorption rate of the sound absorption panel of the present invention configured as described above was obtained the following table.

상기의 실험결과를 참조하면, 본 고안의 흡음판넬은 KSF 2805 에 의한 흡음율 이상의 효과를 얻을 수 있다는 것을 알 수 있다.Referring to the above experimental results, it can be seen that the sound absorbing panel of the present invention can obtain more than the sound absorption rate by KSF 2805.
본 고안의 방음벽용 흡음판넬은 판넬의 두께를 200 mm 로 하고 판넬 내부의 전방에 두께 100 mm, 밀도 32 kg/cm3인 흡음재를 설치하고 흡음재 지지부는 개구를 형성하여 외부로부터 인입된 소음이 흡음재를 통과하고 흡음재 후방의 판넬 내부공간에서 돌아다녀 흡음 효과가 종래의 판넬보다 우수한 것을 알 수 있다.The sound absorbing panel for soundproof wall of the present invention has a thickness of 200 mm and a sound absorbing material having a thickness of 100 mm and a density of 32 kg / cm 3 is installed in front of the inside of the panel. It can be seen that the sound-absorbing effect is superior to the conventional panel by passing through and walking around the panel interior space behind the sound absorbing material.
