본 고안은 방음판의 구조에 관한 것으로, 음파를 내부에서 소멸시키도록 방음효과를 극대화한 방음판의 구조에 관한 것이다.The present invention relates to the structure of the sound insulation panel, and relates to the structure of the sound insulation plate to maximize the sound insulation effect to extinguish the sound waves from the inside.

산업의 발달로 인하여 상업 및 공업 지역은 물론 주거지역까지도 소음의 문제가 심각하게 대두되고 있다. 특히 최근에 증가한 자동차로 인한 고음공해는 아주 심각한 문제가 되고 있다.Due to the development of the industry, the noise problem is seriously raised not only in commercial and industrial areas but also in residential areas. In particular, the recent high sound pollution caused by cars has become a very serious problem.

이러한 소음 문제를 해결하기 위하여 사용되는 종래의 일반적인 방음판은 석면판 또는 유리섬유등을 사용하고 있으며, 이보다 다소 진보한 것으로 흡음면(2)과 석고판(1)을 결합한 방음판이 사용되고 있다.(제1도 감조)Conventional sound insulation boards used to solve such noise problems are asbestos plates or glass fibers, which are more advanced. Sound insulation panels combining the sound absorbing surface 2 and the plaster board 1 are used. Bird's eye diagram)

그러나 이러한 종래의 방음판은 기능적 효과가 기대치보다 낮아 방음판으로써의 기능을 다하지 못하고 있다. 그리고 통상 대로변, 특히 고속도로변에 사용되고 있는 방음판은 음파의 진동을 자체내에서 흡수하는 방식보다는 대응하는 진동판의 사이에서 음파를 서로 반사시켜 에너지를 소멸시키는 방식을 사용하고 있어 충분한 방음의 효과를 기대하는 것은 어렵다.However, such a conventional sound insulation board is unable to fulfill its function as a sound insulation board because its functional effect is lower than expected. In general, soundproof plates used on roadsides, especially on highways, are used to reflect the sound waves and to dissipate energy between the corresponding diaphragms, rather than absorbing the vibrations of the sound waves within themselves. It is difficult.

본 고안의 이러한 문제점을 해결하기 위하여 안출된 것으로, 음파가 가지고 있는 에너지를 진동판 자체내에서 흡수함으로써 효과적인 방음판을 제공하는 것을 목적으로 한다.In order to solve this problem of the present invention, an object of the present invention is to provide an effective soundproofing plate by absorbing the energy of sound waves in the diaphragm itself.

이러한 목적을 달성하기 위한 본 고안의 방음판의 구조는 전달된 음파를 그 내부에서 약화시키고 진동에너지로 변환하는 흡음부재와, 상기 흡음부재의 때면에서 진동을 흡수하기 의한 진동흡수쿠션과, 잔류음파를 흡수하는 흡입면 및 음파를 차단하기 위한 석고관으로 구성된다.The structure of the soundproof plate of the present invention for achieving this purpose is a sound absorbing member for attenuating the transmitted sound waves therein and converting it into vibration energy, a vibration absorbing cushion by absorbing vibrations at the time of the sound absorbing member, and residual sound waves It consists of a suction tube and a gypsum tube to block sound waves.

첨부한 도면에 의거하여 본 고안을 더욱 상제히 설명하면 다음과 같다.Referring to the present invention in more detail based on the accompanying drawings as follows.

제2도 내지 제4도에 도시된 바와같이 본 고안에 의한 방음판의 구조는 구리의 박판으로 굴곡 성형된 흡음부재(6)와 상기 흡음 부재로 전달되는 진동 및 음파를 흡수하는 진동흡수쿠션(5)과, 진동흡수쿠션의 일면에 부착되는 방음지(3), 잔류음파를 흡수하기 위한 흡음면(2), 그리고 음파격절기능을 하는 석고판(1)으로 구성된다.As shown in FIGS. 2 to 4, the structure of the soundproof plate according to the present invention is a sound absorbing member 6 bent and formed into a thin sheet of copper and a vibration absorbing cushion for absorbing vibrations and sound waves transmitted to the sound absorbing member 5. ), A soundproof paper (3) attached to one surface of the vibration absorbing cushion, a sound absorbing surface (2) for absorbing residual sound waves, and a gypsum board (1) having a sonic fracture function.

전달되는 음파에 직접 부딪히는 흡음부재(6)는 구리와 같이 음파의 진동에 민감한 얇은 박판으로 성형하되, 여러번 굴곡진 상태로 만들어진다. 그리고 상기 흡음 부재(6)는 복수개의 흡음편(61)을 구비하는데, 상기 흡음편(61)은 흡음부재(6)의 표면을 절개하여 밖으로 약간 돌출된 형상으로 성형되어 전달되는 음파를 흡음부재의 내면으로 유도함에 동시에 음파의 진동을 흡수하는 역활을 한다. 즉 제2도에 도시된 바와같이 굴곡진 흡음부재(6)의 외면에는 복수개의 흡음편(61)이 성형되어 있다.The sound absorbing member 6 which directly hits the sound wave to be transmitted is molded into a thin sheet sensitive to the vibration of the sound wave, such as copper, but is made in a curved state several times. And the sound absorbing member 6 is provided with a plurality of sound absorbing pieces 61, the sound absorbing piece 61 is formed by cutting the surface of the sound absorbing member 6 in a shape projecting slightly out of the sound absorbing member It acts to absorb the vibration of sound waves while guiding it to the inner surface of it. That is, a plurality of sound absorbing pieces 61 are formed on the outer surface of the curved sound absorbing member 6 as shown in FIG.

전달된 음파는 흡음부재 사이에서 진동하게 되고, 일부는 흡음편(61)을 통하여 내면으로 들어가 내부에서 진동을 일으키도록 구성된다.The transmitted sound waves are vibrated between the sound absorbing members, and part of the sound waves enter the inner surface through the sound absorbing pieces 61 and are configured to cause vibrations therein.

상기 흡음 부재(6)의 배면에는 음소멸 진동흡수쿠션(5)이 부착된다.The sound-absorbing vibration absorbing cushion 5 is attached to the rear surface of the sound absorbing member 6.

진동흡수쿠션(5)은 고무재질의 미립자들로 구성되는데 음소멸 및 진동흡수, 그리고 통기의 특성이 있다. 상기 진동흡수쿠션(5)에 대하여 좀더 상세하게 설명하기로 한다. 진동흡수쿠션(5)은 고무의 미립자들을 접착한것으로 각각의 미립자 사이의 공극을 그대로 유지한체 접착하여 통기성 및 진동 흡수성이 우수한 물질로 구성하는 것이 바람직하다. 고무 미립자들은 통기성 및 진동 흡수성을 유지하도록 하기 위하여 각각의 미립자 사이에 간격을 충분히 유지하도록 말밤의 형태이거나 별 모양등 서로 밀착되더라도 그들 사이의 간격을 충분히 유지할 수 있는 것이 아주 바람직하다.The vibration absorbing cushion 5 is composed of fine particles of rubber material, and has characteristics of annihilation, vibration absorption, and aeration. The vibration absorbing cushion 5 will be described in more detail. The vibration absorbing cushion 5 is made of a material having excellent breathability and vibration absorption by adhering the fine particles of the rubber to maintain the voids between the fine particles as it is. It is highly desirable that the rubber fine particles can sufficiently maintain the space therebetween even if they are in close contact with each other, such as in the form of a chestnut, so as to maintain sufficient spacing between the respective fine particles to maintain breathability and vibration absorption.

그러나 반드시 이러한 재질일 필요는 없으며 다공질의 고무재등으로 본 고안의 방음판을 구성하는 것도 가능하다. 이러한 진동흡수쿠션(5)은 상기 흡음부재(6)에 의하여 생긴 진동을 흡수하기 위함이다.However, it is not necessarily required to be such a material, it is also possible to constitute the soundproof plate of the present invention made of a porous rubber material. The vibration absorbing cushion 5 is for absorbing the vibration generated by the sound absorbing member (6).

진동흡수쿠션의 배면에는 방음지(3)를 부착하고, 그 배면에는 흡음면(2)을 장착하여 잔류 음파를 제거하도록 구성한다. 그리고 상기 흡음면(2)의 배면에는 마지막으로 음파를 차단하기 위한 석고판(1)을 설치한다.The sound absorbing paper 3 is attached to the back of the vibration absorbing cushion, and the sound absorbing surface 2 is attached to the back of the vibration absorbing cushion to remove residual sound waves. And on the back of the sound absorbing surface (2) is finally installed gypsum board (1) for blocking the sound waves.

이상과 같이 구성되는 본 고안 방음판의 작동원리 및 효과를 설명하기로 한다. 실제로 음파가 본 고안 방음판에 전달되면 고강도의 소음의 음파는 흡음부재(6)와 부딪히게 된다. 굴곡진 흡음부재에 부딪힌 음파는 흡음부재(6)의 굴곡사이 및 흡음편(61)을 통해서 그 내부로 유도된다. 따라서 전달된 음파는 흡음부재의 굴곡사이및 내부에서 불규칙적으로 반사되어 그 에너지가 점점 약해진다. 여기서 음파가 가지고 있던 에너지는 흡음부재의 진동을 일으킴과 동시에 그 내부에서 여리번의 반사에 의하여 약해지게 되는 것이다. 그리고 흡음부재의 진동은 그 이면에 부착된 진동흡수쿠션(5)에 의하여 대부분 흡수된다. 상기와 같이, 일단 흡음부재와 진동흡수쿠션을 통하여 약화된 음파는 이 단계에서 미약한 음파만이 이곳을 통과하게 된다. 지금까지 남아있는 음파는 방음지(3) 및 흡음면(2)에서 흡수되어 대부분 차단된다. 그리고 상기 흡음면의 뒤에 부착된 석고판은 음파를 완전히 차단하여 다시 흡음면(2) 또는 방음지(3)을 통하여 잔류음파가 제거되는 겻이다.The operation principle and the effect of the soundproof plate of the present invention configured as described above will be described. In fact, when the sound wave is transmitted to the soundproof plate of the present invention, the sound wave of high intensity noise is hit by the sound absorbing member 6. Sound waves hit against the curved sound absorbing member are guided therein between the curved portions of the sound absorbing member 6 and through the sound absorbing piece 61. Therefore, the transmitted sound waves are irregularly reflected between and inside the bends of the sound absorbing member, and their energy is gradually weakened. Here, the energy of the sound waves causes vibration of the sound absorbing member and at the same time, it is weakened by reflection of several times therein. The vibration of the sound absorbing member is mostly absorbed by the vibration absorbing cushion 5 attached to the rear surface of the sound absorbing member. As described above, the sound wave once weakened through the sound absorbing member and the vibration absorption cushion passes only the weak sound wave at this stage. The sound waves remaining so far are absorbed by the soundproof paper 3 and the sound absorbing surface 2 and mostly blocked. The gypsum board attached to the back of the sound absorbing surface completely blocks the sound waves and removes the remaining sound waves through the sound absorbing surface 2 or the soundproof paper 3 again.

상술한 바와같이 본 고안에 의한 방음판의 구조는 절단되는 음파를 일단 흡음부재의 내부에서 약화시키고, 진동으로 변환시키되, 상기 진동은 진동흡수쿠션에 의하여 대부분 흡수되고, 나머지 잔류음파는 방음지(3)와 흡음면 및 석고판을 통하여 거의 대부분 제거되도록 구성되어 있어서, 소음을 방지하는데 탁월한 효과가 있는 것이다.As described above, the structure of the sound insulation board according to the present invention weakens the sound waves to be cut once inside the sound absorbing member and converts them into vibrations, but the vibrations are mostly absorbed by the vibration absorption cushions, and the remaining residual sound waves are soundproof papers (3). And it is configured to be removed almost through the sound absorbing surface and plasterboard, it is an excellent effect in preventing noise.
