친환경 방음부재{SOUNDPROOF MEMBER}Eco-friendly soundproofing material {SOUNDPROOF MEMBER}

본 발명은 건설 분야에 관한 것으로서, 상세하게는 방음벽을 형성하는 방음부재에 관한 것이다.TECHNICAL FIELD The present invention relates to the field of construction, and more particularly, to a soundproof member for forming a soundproof wall.

방음벽이란, 소음의 전달과정에서 소음을 감쇠시켜 주변지역의 전반적인 소음분포를 일정기준 이하로 낮추어 주는 소음저감대책용 구조물을 말한다.A sound barrier is a structure for noise reduction that reduces the noise in the process of transmitting noise and lowers the overall noise distribution in the surrounding area below a certain standard.

방음벽의 종류에는 흡음형(음파의 대부분을 흡수함), 반사형(방음판에 의해 음파의 대부분을 반사함), 간섭형(입사되는 음파와 반사되는 음파가 섞여 감쇠됨), 공명형(방음판에 구멍이 뚫려 있고 내부에 공동이 있어 음파가 공명에 의해 감쇠됨) 등이 있다.Types of sound barriers include sound absorbing type (which absorbs most of the sound wave), reflection type (reflecting most of the sound wave by the soundproof plate), interference type (attenuated mixture of incident and reflected sound waves), and resonance type (holes in the soundproof plate). Is open and has a cavity inside so that the sound waves are attenuated by resonance.

도 1,2는 종래의 방음벽 및 이를 구성하는 방음부재의 구조를 도시한 것이다.1 and 2 illustrate the structure of a conventional soundproof wall and a soundproof member constituting the same.

도시된 바와 같이, 종래의 방음벽은 소정 간격으로 배치된 복수개의 지주(10) 사이에 복수의 방음부재(20)가 상하방향으로 적층됨으로써 구성되는 것이 일반적이다.As shown in the drawing, a conventional soundproof wall is generally configured by stacking a plurality of soundproof members 20 in a vertical direction between a plurality of struts 10 arranged at predetermined intervals.

한편, 친환경적 건설 구조가 강조되는 요즈음, 위 방음부재를 목재 또는 이 에 상응하는 재질로 형성함으로써, 도로의 차량 운행자 및 주변 주민에게 쾌적한 환경을 제공하기 위한 연구가 이루어지고 있다.On the other hand, these days when the environmentally sound construction structure is emphasized, by forming the above soundproof member made of wood or a corresponding material, a study to provide a pleasant environment for the vehicle operator and the residents of the road.

There is.

이를 극복하기 위하여, 목분, 섬유, 합성수지의 복합재질에 의해 방음부재를 구성하는 경우, 목재의 질감을 살리면서도 위와 같은 문제를 극복할 수 있다는 장점이 있다.In order to overcome this, when the soundproof member is composed of wood, fiber, synthetic resin composite material, there is an advantage that can overcome the above problems while maintaining the texture of the wood.

그러나, 이러한 복합재질에 의해 방음부재(20)를 형성하는 경우라도 다음과 같은 문제가 지적되었다.However, the following problem has been pointed out even when the soundproof member 20 is formed by such a composite material.

목분, 섬유, 수지의 복합재질은 기본적으로 강도 및 내구성이 우수하지만, 흡음 및 차음 성능이 타 재료에 비해 떨어진다는 단점이 있다.The composite material of wood flour, fiber, and resin is basically superior in strength and durability, but has a disadvantage in that sound absorption and sound insulation are inferior to other materials.

따라서, 도 2에 도시된 바와 같이, 목분과 수지의 복합재질에 의해 방음부재(20)의 본체(21)를 형성하고, 이에 흡음재(22)를 설치하는 경우, 타 재질을 사용하는 경우에 비해 방음벽의 전체적 성능이 좋지 못하다는 문제가 제기되는 것이다.Therefore, as shown in FIG. 2, when the main body 21 of the soundproof member 20 is formed of a composite material of wood powder and resin, and the sound absorbing material 22 is installed therein, the material is compared with the case of using other materials. The problem is that the overall performance of the sound barrier is not good.

이하, 첨부도면을 참조하여 본 발명의 실시예에 관하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 3 이하에 도시된 바와 같이, 본 발명은 기본적으로 지주(10) 사이에 설치 되어 방음벽을 형성하는 방음부재(100)에 관한 것으로서, 목분, 수지 및 섬유를 포함하는 복합재질에 의해 형성된 본체(110); 본체(110)의 전방에 형성된 흡음재 장착부(120); 흡음재 장착부(120)에 장착된 흡음재(200); 흡음재 장착부(120)의 외측에 형성된 외측 중공부(130);를 포함하여 구성된다.As shown in Figure 3 below, the present invention relates to a soundproofing member 100 which is basically installed between the struts 10 to form a soundproof wall, the body formed by a composite material containing wood powder, resin and fibers ( 110); Sound absorbing material mounting portion 120 formed in front of the main body 110; Sound absorbing material 200 mounted to the sound absorbing material mounting portion 120; It is configured to include; the outer hollow portion 130 formed on the outside of the sound absorbing material mounting portion 120.

즉, 방음부재 본체(110)를 목분, 수지 및 섬유를 포함하는 복합재질에 의해 형성함으로써, 목재의 질감을 살리면서 우수한 강도 및 내구성을 확보하도록 하는 한편, 흡음재 장착부(120)의 외측에 외측 중공부(130)를 형성함으로써, 흡음 및 차음 성능을 보완한 것이다.That is, by forming the sound-proof member body 110 by a composite material including wood powder, resin and fibers, while maintaining the texture of the wood to ensure excellent strength and durability, while the outer hollow on the outside of the sound absorbing material mounting portion 120 By forming the unit 130, the sound absorption and sound insulation performance is complemented.

목분, 수지 및 섬유를 포함하는 복합재질은 강도 및 내구성이 대단히 우수하지만, 강재나 콘크리트에 비해 비중이 적으므로, 소음 및 진동을 차폐하는 성능이 떨어진다는 단점이 있다.Composite materials including wood flour, resin, and fiber are extremely excellent in strength and durability, but have a specific gravity less than steel or concrete, and thus have a disadvantage in that noise and vibration shielding performance is poor.

구조체 내부에 형성된 중공부는 외부로부터 전달된 소음 및 진동을 공명현상에 의해 소멸시키는 특성을 갖는다.The hollow part formed inside the structure has a characteristic of extinguishing noise and vibration transmitted from the outside by resonance.

따라서, 위 복합재질에 의한 방음부재(100)에 외측 중공부(130)가 형성되는 경우, 위 흡음재(200)에 의해 1차로 흡음된 이후 전달된 소음 및 진동을 위 외측 중공부(130)에 의해 소멸시키므로, 방음부재(100)의 외측에 대한 소음 및 진동을 최소화할 수 있다는 장점이 있다.Therefore, when the outer hollow portion 130 is formed in the soundproofing member 100 by the above composite material, the noise and vibration transmitted after the first sound absorption by the upper sound absorbing material 200 to the upper outer hollow portion 130. By extinction, there is an advantage that the noise and vibration to the outside of the soundproof member 100 can be minimized.

또한, 본체(110)의 크기가 일정하다는 전제 하에, 위 중공부(130)의 형성으로 인하여 소요되는 재료의 양을 절감할 수 있으므로, 경제적 측면에서도 유리한 효과를 얻을 수 있다.In addition, under the premise that the size of the main body 110 is constant, the amount of material required due to the formation of the hollow portion 130 may be reduced, and thus, an advantageous effect may be obtained in terms of economy.

결과적으로, 본 발명에 의한 방음부재는 친환경적 재질을 사용하면서도, 구조의 개선에 의해 그 재질의 약점을 보완함으로써, 우수한 흡음 및 차음 성능을 갖도록 한다는 효과가 있는 것이다.As a result, the soundproof member according to the present invention has the effect of having excellent sound absorption and sound insulation performance by using the environmentally friendly material, by compensating for the weakness of the material by the improvement of the structure.

방음부재(100) 본체(110)를 형성하는 복합재질은 폴리프로필렌, 폴리에틸렌 등의 수지 30~40 중량%; 그라스화이버 등의 보강섬유 15~20 중량%; 목분(왕겨 포함) 40~50 중량%;를 포함하는 구성을 취하는 것이 가장 바람직한 것으로 나타났다.The composite material forming the soundproof member 100 main body 110 is 30 to 40% by weight of a resin such as polypropylene and polyethylene; 15 to 20% by weight of reinforcing fibers such as glass fibers; It was found that it is most desirable to take a composition comprising; 40-50% by weight of wood flour (including chaff).

본체(110)에 외측 중공부(130)를 형성하는 방식에는 여러가지가 있을 수 있는데, 도 3에서는 본체(110)가 상하방향으로 형성된 격벽(111); 외측에 형성된 외측판(112);을 구비하고, 흡음재 장착부(120)는 격벽(111)의 전방에 형성되고, 외측 중공부(130)는 격벽(111) 및 외측판(112)의 사이 영역에 의해 형성된 실시예를 도시한 것이다.There may be various ways of forming the outer hollow part 130 in the main body 110, in FIG. 3, the partition wall 111 in which the main body 110 is formed in the vertical direction; An outer plate 112 formed at an outer side thereof, and the sound absorbing material mounting unit 120 is formed in front of the partition wall 111, and the outer hollow part 130 is disposed in an area between the partition wall 111 and the outer plate 112. It shows an embodiment formed by.

도 4,5에 도시된 바와 같이, 흡음재 장착부(120) 및 외측 중공부(130)는 상하방향으로 복수가 형성되고, 복수의 흡음재 장착부(120) 및 외측 중공부(130) 사이 영역에 중간 중공부(140)가 형성된 구조를 취하는 경우, 상술한 차음 성능의 향상 효과를 더욱 증대할 수 있다.4 and 5, the sound absorbing material mounting portion 120 and the outer hollow portion 130 are formed in plural in the vertical direction, and the intermediate hollow in the region between the plurality of sound absorbing material mounting portions 120 and the outer hollow portion 130. When taking the structure in which the part 140 is formed, the above-mentioned improvement effect of the sound insulation performance can be further increased.

이러한 중간 중공부(140)는 흡음재(200)에 의한 흡음 후, 본체(110)에 전달된 소음 및 진동을 위 외측 중공부(130)와 함께 더욱 저감할 수 있기 때문이다.This is because the intermediate hollow portion 140 can further reduce the noise and vibration transmitted to the main body 110 together with the upper outer hollow portion 130 after the sound absorption by the sound absorbing material 200.

도 4,5는 본체(110)가 격벽(111)에서 내측으로 연장형성된 복수의 지지판(113)을 구비하고, 중간 중공부(140)가 복수의 지지판(113)의 사이 영역에 의해 형성된 실시예를 도시한 것이다.4 and 5 illustrate embodiments in which the main body 110 includes a plurality of support plates 113 extending inwardly from the partition wall 111, and the intermediate hollow part 140 is formed by a region between the plurality of support plates 113. It is shown.

중간 중공부(140)가 중간 격벽(114)에 의해 내측 중간 중공부(141) 및 외측 중간 중공부(142)로 구분되는 경우, 소음 및 진동의 저감 효과를 더욱 크게 얻을 수 있다.When the intermediate hollow part 140 is divided into the inner intermediate hollow part 141 and the outer intermediate hollow part 142 by the intermediate partition wall 114, the effect of reducing noise and vibration can be further increased.

여기서, 중간 격벽(114)은 격벽(111)과 동일한 선상에 설치될 수도 있으나, 격벽(111)의 내측에 설치되는 경우, 벽체가 지그재그 형상으로 형성됨으로써, 더욱 안정적인 구조를 얻을 수 있다는 장점이 있다.Here, the middle partition wall 114 may be installed on the same line as the partition wall 111, but when installed inside the partition wall 111, the wall is formed in a zigzag shape, there is an advantage that a more stable structure can be obtained. .

중간 격벽(114)이 흡음재 장착부(120)의 중앙부 상하에 설치되는 경우, 위 효과를 더욱 크게 얻을 수 있다.When the middle partition wall 114 is installed above and below the center of the sound absorbing material mounting portion 120, the above effect can be obtained even more.

중간 중공부(140)의 내측에 반사판(150)이 설치되고, 반사판(150)의 상하에는 트임부(121)가 형성되며, 흡음재 장착부(120)는 트임부(121)의 외측에 형성된 구조를 취하는 경우, 도로의 소음의 일부는 반사판(150)에 의해 내측으로 반사시키고, 다른 일부만을 흡음재(200) 및 중공부(130,140)에 의해 흡음하면 되므로, 외측으로 전달되는 소음 및 진동의 양을 더욱 저감할 수 있다는 효과가 추가된다.The reflection plate 150 is installed inside the intermediate hollow part 140, and a trimming part 121 is formed above and below the reflection plate 150, and the sound absorbing material mounting part 120 has a structure formed outside the trimming part 121. When taking, part of the noise of the road should be reflected inward by the reflection plate 150, and only the other part may be absorbed by the sound absorbing material 200 and the hollow portions 130 and 140, thereby further increasing the amount of noise and vibration transmitted to the outside. The effect of reducing can be added.

도 6에 도시된 바와 같이, 트임부(121)에는 흡음재(200)를 덮어 보호하도록 타공판(210)을 설치하는 경우, 타공판(210)의 전면에 의한 반사효과를 얻을 수 있으므로, 상술한 효과를 더욱 크게 얻을 수 있다는 장점이 있다.As shown in FIG. 6, when the perforated plate 210 is installed in the trim part 121 to cover and protect the sound absorbing material 200, the reflection effect by the front surface of the perforated plate 210 may be obtained. The advantage is that it can be obtained even larger.
