Description
본원 발명은 건물의 실내에 설치될 수 있는 흡음패널 및 이용한 사무용 파티션에 관한 것으로서, 흡음, 및 난연성을 보강한 것이다. 보다 상세하게는 통공이 골고루 평면에 형성된 전면시트와 후면시트, 그리고 중간에 허니콤중간재를 구비하되, 허니콤중간재와 전후면시트 사이에는 부직포가 부가된 것이다. The present invention relates to a sound-absorbing panel that can be installed in the interior of a building and an office partition using the sound-absorbing panel, and to reinforce the sound-absorbing and flame retardant. In more detail, a front sheet and a rear sheet having through-holes evenly formed on a flat surface, and a honeycomb intermediate material are provided in the middle, but a nonwoven fabric is added between the honeycomb intermediate material and the front and rear sheets.
최근 우리나라의 주택뿐만 아니라, 공공기관 건물, 그리고 나아가 공연장 등에서는 다양화된 요구에 따라 다양한 모습으로 변화되고 있다. 이에 건축물의 실내디자인도 고급화, 다양화 그리고 차별화의 디자인으로 발전해 가면서 실내공간의 분위기를 좌우하는 실내마감재의 중요성이 부각되고 있다.Recently, not only houses in Korea, but also public institution buildings, and even concert halls, are being transformed into various shapes according to diversified demands. Accordingly, as the interior design of buildings develops into advanced, diversified, and differentiated designs, the importance of interior finishing materials that influence the atmosphere of the interior space is being emphasized.
또한, 건축물의 실내마감재는 실내의 소음을 흡수하는 흡음재의 역할이 필수적이고, 화재발생의 경우를 염두하여 불연 또는 난연소재로 이루어져야 하는 것이 의무사항이 되어가고 있다. In addition, the role of sound absorbing material for absorbing indoor noise is essential for interior finishing materials of buildings, and it is becoming an obligation to be made of non-combustible or flame-retardant materials in consideration of the occurrence of a fire.
이러한 건축내장재의 흡음성능 개선을 위하여 일반적인 흡음패널의 경우 표면에 다수개의 타공을 구비하여 소리를 감소시키거나 일정한 패턴으로 돌출되어 돌출부위 사이로 소리가 반사되는 형상이 필요하다. 계란판과 같이 돌기부와 홈부가 구비된 형태로 만들어지는 것이 일반이다. In order to improve the sound-absorbing performance of such building interior materials, in the case of a general sound-absorbing panel, a plurality of perforations are provided on the surface to reduce the sound, or a shape in which the sound is reflected between the protruding parts by protruding in a certain pattern is required. It is generally made in a form provided with a protrusion and a groove, such as an egg plate.
그러나, 이러한 흡음판의 경우 외관이 흉칙스럽거나 적어도 미려하지 못하여 건축내장재로 활용하기 적합하지 아니하며, 흡음성능을 좋게 하다보면, 오히려 표면에 형성된 흡음 통공을 통해서 화재시에 불길이 취약하게 되는 문제가 생기게 된다. However, in the case of such a sound-absorbing plate, it is not suitable for use as a building interior material because the appearance is ugly or at least not beautiful. .
그럼에도 불구하고 현재까지 이러한 문제점들을 일소에 해결할 수 있는 건축용 내장재가 개발되지 못한 상태였다. 종래기술로는 대한민국특허등록 제10-1574380호 (2015. 11. 27. 등록)에는 다수의 흡음공이 형성된 마이크로 공명층을 포함하는 흡음시트와 상기 흡음시트와 흡음시트 외면을 커버하는 흡음형 방음패널을 제안하고 있다. Nevertheless, up to now, interior materials for construction that can solve these problems in a sweeping condition have not been developed. As a prior art, Republic of Korea Patent Registration No. 10-1574380 (registered on November 27, 2015) has a sound-absorbing sheet including a micro-resonance layer in which a plurality of sound-absorbing holes are formed, and a sound-absorbing soundproofing panel covering the outer surface of the sound-absorbing sheet and the sound-absorbing sheet. is proposing
그러나, 상기 특허문에서도 흡음시트는 결로현상문제를 해결할 수 없고, 화재의 취약한 구조이고, 통공이 외부에서 보이는 구조로 되어있어 미관상의 한계점이 있다는 문제점이 남아 있다. However, in the above patent, the sound-absorbing sheet cannot solve the problem of dew condensation, it is a weak structure for fire, and the through hole has a structure that is visible from the outside, so there is a problem that there is an aesthetic limitation.
본원 발명의 발명자는 최고의 건축용 내장재를 개발한다는 사명감가운데, 흡음성능, 결로방지성능, 난연성능, 미려한 외관을 모두 해결할 수 있는 복합기능의 건축내장재를 개발하게 되었다. The inventor of the present invention has developed a building interior material with a complex function that can solve all of the sound absorption performance, condensation prevention performance, flame retardancy performance, and beautiful appearance in the sense of mission to develop the best interior material for construction.

도 2는 본원 발명의 흡음패널을 분해하여 도시한 분해사시도이다. 사각프레임 내부에 허니콤중간재가 삽입된다. 허니콤중간재는 평면에 대하여 수직방향으로 허니콤 모양으로 통공이 형성된 자재이다. 허니콤중간재는 통공의 측면방향으로 밀폐된 형태이다. Figure 2 is an exploded perspective view showing the sound-absorbing panel of the present invention by disassembling. A honeycomb intermediate material is inserted inside the rectangular frame. The honeycomb intermediate material is a material in which a hole is formed in a honeycomb shape in the vertical direction with respect to the plane. The honeycomb intermediate material is sealed in the lateral direction of the through hole.
상기 허니콤중간재가 상기 사각프레임 내부에 삽입된 상태에서 상기 허니콤중간재의 양 측면에 제1부직포와 제2부직포가 부착된다. 또한 상기 제1부직포 전면에는 전면시트가 상기 제2부직포 후면에는 후면시트가 부착된다. A first nonwoven fabric and a second nonwoven fabric are attached to both sides of the honeycomb intermediate material in a state in which the honeycomb intermediate material is inserted into the rectangular frame. In addition, a front sheet is attached to the front surface of the first nonwoven fabric and a rear sheet is attached to the rear surface of the second nonwoven fabric.
이때 전면시트와 후면시트는 관통하는 통공이 골고루 형성된 것이다. 이와 같이 사각프레임에 의해서 허니콤중간재 양면에 부착된 부직포와 시트재는 외부의 하중에 대해서 일정한 형태를 유지하게 된다. At this time, the front sheet and the rear sheet are evenly formed through the through holes. In this way, the nonwoven fabric and the sheet material attached to both sides of the honeycomb intermediate material by the square frame maintain a constant shape with respect to the external load.
상기와 같은 구조의 흡음패널은 사무용 공간 파티션으로 활용될 수 있도록 하기 위해서 사각프레임에는 연결프레임이 구비되도록 한다. 연결프레임은 인접한 복수개의 흡음패널을 상호 연결하여 연속적으로 결합하기 위한 것이다.The sound-absorbing panel of the above structure is to be provided with a connection frame in the square frame in order to be utilized as an office space partition. The connecting frame is for connecting a plurality of adjacent sound-absorbing panels to each other and continuously combining them.
이와 같이 구성된 흡음패널의 작동원리는 도 3에서 도시된 바와 같다. 즉, 외부의 소음은 음파에 형태로서 흡음패널의 외면에 구비된 통공을 통해서 흡입되고 부직포를 관통하게 된다. 그러나 일단 흡입된 음파는 허니콤중간재 내부에서 반사되면서 소멸되거나 반사된 음파는 약해진 상태에서 다시 부직포를 관통하기 어렵다. 특히 부직포는 불규칙하게 실이 얽혀있는 구조이기 때문에 음파는 한번 부직포를 관통하였다고 하더라도 다시 부직포를 관통하여 외부로 유출될 수 없다. The operating principle of the sound-absorbing panel configured as described above is shown in FIG. 3 . That is, the external noise is sucked through the through hole provided on the outer surface of the sound-absorbing panel in the form of sound waves and penetrates the nonwoven fabric. However, once the absorbed sound wave is reflected inside the honeycomb intermediate material, it is extinguished, or the reflected sound wave is difficult to penetrate through the nonwoven fabric again in a weakened state. In particular, since the nonwoven fabric has a structure in which threads are irregularly intertwined, even if the sound wave has penetrated the nonwoven fabric once, it cannot pass through the nonwoven fabric again and flow out to the outside.
본원 발명의 흡음패널은 양면에 흡음성이 구비되도록 양면의 전면시트와 후면시트에 모두 관통하는 통공이 형성되는 것이 바람직하다. 하지만 용도에 따라서 일면만 흡음성을 구비하면 충분한 경우도 있다. 즉, 벽면에 설치하는 경우에는 일면만 흡음성이 있으면 되기 때문에 전면시트는 통통이 구비되고 부직포를 구비하도록 하지만, 후면시트에는 통공이 없고 심지어 부직포를 부가할 필요 조차도 없다. It is preferable that the sound-absorbing panel of the present invention has a through hole penetrating through both the front sheet and the rear sheet on both sides so that the sound absorption is provided on both sides. However, depending on the use, if only one side is provided with sound absorption, there are cases where it is sufficient. That is, when installed on the wall, only one side has sound absorbing properties, so the front sheet is provided with a tong and a nonwoven fabric, but the rear sheet does not have a through hole and it is not even necessary to add a nonwoven fabric.
