본 고안은 자동차의 소음을 차단하는 방음벽에 관한 것으로 케이스의 내부에 방음 및 흡음 효과가 뛰어난 흡음재를 내삽하되 그 흡읍재의 일면을 울퉁불퉁하게 발포시켜 음의 파장을 최대한으로 차단 및 흡수하도록 한 방음벽에 관한 것이다.The present invention relates to a soundproof wall that blocks noise of a vehicle, and to a soundproof wall interpolating a sound absorbing material having excellent soundproofing and soundproofing effects inside a case, and foaming one surface of the sound absorbing material unevenly to block and absorb sound waves to the maximum. will be.

종래에는 주택이 밀집되어 있는 도로변이나 터널 등에는 자동차의 소음을 방지하게 위하여 유리섬유(Glass Wool)가 내장된 방음벽을 사용하였다.Conventionally, a soundproof wall in which glass fibers are embedded is used in a roadside or a tunnel where houses are concentrated to prevent noise of a vehicle.

즉 전면은 알루미늄 커버로 밀폐되게 하고 후면에는 아연도강판을 사용하여 케이스를 형성한 다음 리벳팅하여 고정하고 그 중간부에 비닐포장된 유리섬유를 내장하여 방음벽으로 사용하였으나, 이와 같은 방법은 아연도 강판이 수분에 약하여 장기간 사용시 부식이 되어 못쓰게 되는 단점이 있었고 흡음을 위하여 유리섬유를 사용하였으나 유리섬유가 수분에 약하기 때문에 이를 보호하기 위하여 유리섬유를 비닐포장하여 사용하므로서 흡음의 효과가 현저화게 떨어지는 단점이 있었으며, 해로운 유리섬유를 사용하기 때문에 제작자나 방음벽이 설치된 곳의 주민들이 괴로움을 당하는 단점이 있었고, 알루미늄으로 된 전면 커버에 통공을 형성하여 흡음의 효과를 기대하였으나 장기간 사용시 통공과 흡음제에 먼지나 이물질이 끼어 흡음의 효과를 현저하게 저하시키는 등의 문제점이 있다.In other words, the front side was sealed with aluminum cover, and the case was formed by using galvanized steel plate on the back side, and then fixed by riveting. Steel plate is weak in moisture and can not be corroded when used for a long time. Glass fiber is used for sound absorption, but glass fiber is wrapped in vinyl to protect it. There was a disadvantage that the manufacturer or residents in the place where the soundproof wall was installed suffered from the use of harmful glass fiber, and the air hole formed in the front cover of aluminum was expected to absorb sound. Foreign matter is caught and the effect of sound absorption There is a problem such that reduced.

본 고안은 상기와 같은 문제점을 해결하기 위하여 안출한 것으로서 전면 커버와 본체 케이스 사이에 인체에 영향이 적고 흡음의 효과가 뛰어난 흡음재를 삽입한 다음 양측 커버를 체결하여 밀폐되게 하여서 된 것으로서, 본 고안을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been made to solve the above problems as a sound absorbing material having a low impact on the human body and excellent sound absorption effect between the front cover and the main body case, and then closed both sides by tightening the cover, the present invention When described in detail with the accompanying drawings as follows.

전면 커버와 본체 케이스 내부에 흡음재가 내장된 방음벽에 있어서, 본체 케이스(1)와 수개의 장공(2)이 형성된 전면 커버(3)의 상, 하 양단을 절곡시켜 체결부(4)(5)를 형성하여 체결고정하고 그 상, 하 일측에는 통공(6)(6')을 형성하여 상부 중앙 양측에는 돌출부(7)(7')를 형성하여 체결홈(8)(8')이 형성된 양측면 커버(9)(9')와 체결하고 본체 케이스(1)의 내부에는 폴리커버네이트(P.C)로 된 흡음재(10)를 내장하되 흡음재(10)의 전체에는 미세한 기포를 형성하고 일측면에는 오목볼록한 요철부(11)가 형성하여서 된 것이다.In the soundproof wall in which the sound absorbing material is incorporated in the front cover and the main body case, the upper and lower ends of the front cover 3, in which the main body case 1 and the several long holes 2 are formed, are bent to the fastening portion 4 and 5. And fastening to form a fastening and the upper and lower sides of the through hole (6) (6 ') to form a projection (7) (7') on both sides of the upper center to form the fastening grooves (8) (8 ') The cover 9 and 9 ′ are fastened to each other, and a sound absorbing material 10 made of polycoverate (PC) is built into the main body case 1, and a fine bubble is formed in the whole of the sound absorbing material 10 and concave on one side. The convex concave and convex portion 11 is formed.

한편 본 고안은 흡음재(10)로 폴리에틸렌(P.E), 폴리프로필렌(P.P), 폴리우레탄(P.U)등을 사용하여도 본 고안과 동일한 효과를 얻을 수 있다.On the other hand, the present invention can obtain the same effect as the present invention even when using a polyethylene (P.E), polypropylene (P.P), polyurethane (P.U) and the like as the sound absorbing material (10).

이와 같이 형성된 본 고안의 효과를 설명하면 다음과 같다.Referring to the effects of the present invention formed as described above are as follows.

전면 커버(3)에 형성된 장공(2)을 통하여 소음이 흡음재(10)의 요철부(11)에 닿게 되면 소음의 파장이 곡선을 이루고 있기 때문에 오목한 부분에 닿아 흡음재(10)가 소음을 최대한으로 흡수할 수가 있는 것이다.When the noise touches the uneven portion 11 of the sound absorbing material 10 through the long hole 2 formed in the front cover 3, since the wavelength of the noise is curved, the sound absorbing material 10 maximizes the noise. It can be absorbed.

한편 흡음재(10)에 먼지나 이물질이 쌓여 청소를 하거나 비가 오게되면 본체 케이스(1)의 상부에 형성된 통공(6)에 물이 흘러 들어가 물이 흡음재(10)에 쌓인 먼지와 함께 본체 케이스(1)의 하단부에 형성된 통공(6')을 통하여 배수되어 흡음재(10)를 청소하게 되어 흡음의 효과를 언제나 극대화 할 수가 있으며 흡음재(10)가 파손되거나 마모되어 교체할때는 측면 커버(9)를 분리하면 간단하게 교체할 수가 있는 것이다.On the other hand, when dust or foreign matter accumulates on the sound absorbing material 10, or when it comes to cleaning or rain, water flows into the through hole 6 formed in the upper part of the main body case 1, and the water accumulates in the sound absorbing material 10 together with the body case 1 It is drained through the through hole (6 ') formed in the lower end of the) to clean the sound absorbing material 10 can be maximized the effect of sound absorption at any time, when the side cover (9) is removed when the sound absorbing material 10 is damaged or worn You can simply replace it.

또한, 본 고안의 흡음재(10)로 폴리커버네이트(P.C), 폴리에틸렌(P.E), 폴리프로필렌(P.P), 폴리우레탄(P.U) 중 어느 것을 사용하여도 본 고안과 동일한 효과를 얻을 수가 있다.In addition, the same effect as the present invention can be obtained by using any of polycoverate (P.C), polyethylene (P.E), polypropylene (P.P), and polyurethane (P.U) as the sound absorbing material 10 of the present invention.

이상과 같이 본 고안은 본체 케이스의 내부에 요철부가 형성된 흡음재를 내장하므로서 중량이 가벼워 제작이 간편하고 인력이 낭비를 줄일 수 가 있으며 분해 조립이 가능하여 제작시간 절감과 사후관리에도 편리한 유용한 고안이다.As described above, the present invention has a light weight, which is easy to manufacture due to the built-in sound absorbing material in which the uneven portion is formed inside the main body case, which can reduce waste, and can be disassembled and assembled.
