Description
본 고안은 건축용 내장판넬에 관한 것으로서 보다 상세하게는 발포 알루미늄판재의 표면에 합성수지재로 이루어진 섬유재를 접착재를 사용하지 않고 열 융착하여 부착 설치함으로서 흡음율을 향상시키고 미감을 제공하도록 한 건축용 내장판넬에 관한 것이다.The present invention relates to a building interior panel, and more specifically, to a building interior panel that improves sound absorption rate and provides aesthetics by attaching and installing a fiber material made of synthetic resin on the surface of a foamed aluminum sheet without using an adhesive. It is about.
종래 소음방지 및 음향전달을 차단하기 위한 흡음 및 차음기능을 갖는 기존의 내장판넬은 다수의 공지된 기술에서와 같이 내장판넬의 표면을 요철화시키거나 그 표면에 기모성 포지를 부착하여 반사음의 산란 효과로써 소음 및 음향전달을 차단하도록 하고 있는 바, 이러한 종래의 내장판넬은 소음의 흡수가 제대로 행해지지 않고 주로 소음의 산란만으로 그 작용을 수행하기 때문에 그 흡음효과가 상당히 미흡하였고 외관이 미려하지 못한 단점이 있었다. Conventional interior panels having sound absorption and sound insulation functions to prevent noise and block sound transmission are scattered by reflecting irregularities on the surface of the interior panel or by attaching a brushed forge to the surface as in many known technologies. The conventional interior panel has a sound absorption effect which is considerably insufficient and its appearance is insignificant because the conventional interior panel does not absorb sound properly and performs its function only by scattering of noise. There was a downside.
한편 일반적으로 사용되고 있는 흡음재는 석면이나, 그라스울(GLASS WOOL)과 같은 무기 섬유계와, 발포우레탄 및 스치로폼, 발포염화비닐과 같은 유기고분자계, 발포그라스나 발포콘크리트와 같은 무기물계 등이 있다.On the other hand, generally used sound absorbing materials include asbestos, inorganic fiber systems such as glass wool, foamed urethane and styrofoam, organic polymers such as foamed vinyl chloride, and inorganic materials such as foamed glass or foamed concrete.
이중에서 그라스울은 가장 일반적으로 사용되고 있는 방음소재로서, 진동, 풍압, 충격 등에 의해 쉽게 부서지기 때문에 이때 발생되는 분진이 인체에 치명적으로 유해하고, 산업폐기물로 분류되어 폐기시키기에 어려움이 있는 등의 문제가 있다. Among them, glass wool is the most commonly used soundproofing material, and because it is easily broken by vibration, wind pressure, impact, etc., dust generated at this time is harmful to the human body and is difficult to be classified as industrial waste. There is.
또한, 그라스울은 공기중의 수분을 흡수하기 때문에 흡음 특성이 저하될 뿐 아니라 다른 보강재를 사용하는 복합구조에 의해서만이 시공이 이루어지는 단점이 있다.In addition, because glass wool absorbs moisture in the air, the sound absorbing property is not only deteriorated, but there is a disadvantage in that the construction is performed only by a composite structure using other reinforcing materials.
한편, 발포우레탄과 같은 다공체는 흡음 특성은 우수하나 내열성이 낮고, 대형 건물의 내장용으로 시공된 상태에서 화재시 유독가스를 배출하는 문제가 있다. 또한, 발포그라스나 발포콘크리트와 같은 소재들은 내열성은 확보되지만 단위 무게가 무겁기 때문에 건물의 내장용으로 사용하기 어렵고, 흡음 등급을 향상시키기 위해 기계적인 가공을 부가적으로 실시하여야 하는 문제가 있다.On the other hand, a porous body such as foam urethane has excellent sound absorption characteristics, but low heat resistance, there is a problem of emitting toxic gas in case of fire in the state of construction for the interior of a large building. In addition, materials such as foamed glass or foamed concrete are heat-resistant, but the unit weight is heavy, so it is difficult to use for the interior of the building, there is a problem that additional mechanical processing to improve the sound absorption grade.
상술한 바와 같이 종래의 흡음재들은 내열성, 내구성, 흡음성 및 경량성을 골고루 만족시키지 못하는 한계가 있다. 한편, 종래의 알루미늄 섬유를 사용하는 흡음재는 통상적으로 알루미늄 섬유의 직경이 50∼250 μm으로 일정하며 길이가 1cm 이상인 장(長)섬유를 사용하기 때문에 기공의 크기를 줄이기 어려워 일정량 이상의 흡음력을 갖기 어렵다는 문제가 있다.As described above, the conventional sound absorbing materials have limitations that do not satisfy heat resistance, durability, sound absorption and light weight evenly. On the other hand, the sound absorbing material using the conventional aluminum fiber is usually a constant diameter of 50 to 250 μm and the long fiber having a length of 1cm or more is difficult to reduce the size of the pores, it is difficult to have a sound absorbing force of a certain amount or more there is a problem.
상기와 같은 문제점을 감안하여 알루미늄을 발포한 발포알루미늄판재가 제안되었으며 상기 발포알루미늄판재는 수 많은 기공에 의해 음파가 흡수되는 것이나 금속재이기 때문에 내장재로 사용할 때 미감을 제공하기 어려움이 있고 또한 내장재로 사용시 마감재를 부착하여야 하는데 이때 점착제를 사용하여야 하기 때문에 설치작업이 어렵고 점착제에서 방출되는 화학성분 때문에 알러지를 일으키게 되는 문제가 있다.In view of the above problems, a foamed aluminum sheet having been foamed with aluminum has been proposed, and the foamed aluminum sheet has difficulty in providing aesthetics when used as interior materials because it is absorbed by many pores or is a metallic material. At this time, it is necessary to attach the finishing material, which is difficult to install because the adhesive is used, and there is a problem that allergies are caused due to chemical components released from the adhesive.
다른 문제점으로는 내장재로 사용시 금속의 특성에 의해 사람이 충돌하였을 때 충격을 흡수하지 못하고 충돌한 사람에게 충돌시 발생하는 에너지 전부를 전위시키기 때문에 통증을 유발시키거나 충돌이 크면 심할 경우 부상을 입는 등의 문제점이 있다.Another problem is that when using as interior materials, due to the characteristics of the metal, it does not absorb shock when a person collides, and displaces all the energy generated when the person collides. There is a problem.
본 고안은 상기한 문제점을 감안하여 안출한 본 고안은 발포 알루미늄판재의 표면에 합성수지재로 이루어진 섬유수단을 접착제를 사용하지 않고 열융착하여 미감을 제공하도록 함과, 소음을 흡수하면서 단열의 효과를 부가적으로 얻을 수 있는 건축용 내장판넬을 제공하는데 있다.The present invention devised in view of the above problems is to provide aesthetics by heat-sealing the fiber means made of a synthetic resin material on the surface of the foamed aluminum sheet without using an adhesive, and absorbs noise and improves the effect of thermal insulation An additional purpose is to provide building panels for construction.
이러한 본 고안의 목적은 발포 알루미늄판재의 일면 또는 양면에 저융점 단섬유가 혼합되어 이루어진 견면이 접착제를 사용하지 않고 열융착에 의하여 부착되고, 상기 열융착된 견면 위에 단섬유로 되는 웹적층물을 패턴침으로 니들펀칭한 패턴견면 및 펠팅침으로 니들펀칭된 견면 중의 어느 하나가 니들펀칭으로 부착되어 적층된 것을 특징으로 하는 건축용 내장판넬에 의하여 달성된다.The object of the present invention is a web laminate made of short fibers on the one or both sides of the foamed aluminum sheet is attached by heat fusion without the use of an adhesive, and the heat-bonded, It is achieved by a built-in panel for building, characterized in that any one of the pattern face needle needle-punched with a pattern needle and the needle punched needle face is attached and laminated by needle punching.

이하 본 고안의 바람직한 실시예를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
첨부도면 도 1은 본 고안의 기술이 적용된 건축용 내장판넬의 구조를 보여주 는 사시도이며 도 2는 본 고안의 기술이 적용된 건축용 내장판넬의 구조를 보여주는 단면도로서 이에 따르면 본 고안의 건축용 내장판넬(1)은 발포 알루미늄판재(10)의 일면 또는 양면에 합성수지재로 이루어진 섬유수단(20)이 접착제를 사용하지 않고 열융착에 의하여 부착되어 이루어진 구조이다.1 is a perspective view showing a structure of a building interior panel to which the technology of the present invention is applied, and FIG. 2 is a cross-sectional view showing a structure of a building interior panel to which the technology of the present invention is applied. ) Is a structure in which the fiber means 20 made of a synthetic resin material is attached to one side or both sides of the
상기 섬유수단(20)을 발포 알루미늄판재(10)에 부착하는 방법은 발포 알루미늄판재(10)의 표면에 올려 놓고 섬유수단(20)과 발포 알루미늄판재(10)의 접하는 부분을 가열수단을 이용하여 가열하면 상기 섬유수단(20)은 연화되고 발포 알루미늄판재(10)의 표면은 가열되어 열융착에 의한 부착 현상이 일어나 섬유수단(20)과 발포 알루미늄판재(10)가 접착되게 되는 것이다.The method of attaching the fiber means 20 to the
상기 섬유수단(20)이 발포 알루미늄판재(10)의 표면에 부착되면 소음을 흡수하면서 단열의 효과를 부가적으로 얻을 수 있게 되며 더욱이 내장재로 사용시 미감적 아름다움을 재공할 수 있게 되는 것이다. 한편 건축용 외장재 또는 도로면의 방음판넬로 사용되던 발포 알루미늄판재를 건축용 내장재로 사용할 수 있도록 할 수 있는 이점이 있다.When the fiber means 20 is attached to the surface of the
한편 상기 섬유수단(20)은 직포, 부직포 중 어느 하나를 사용할 수 있으며 첨부도면 도 1 및 도 3에 도시된 바와 같이 상기 섬유수단(20)은 단섬유로 되는 웹적층물을 패턴침으로 니들펀칭한 패턴견면을 사용하는 것이 바람직하다. 그 이유는 견면이기 때문에 흡음율의 효율이 향상되고 또한 표면에 무늬 및 모양이 형성되어 있어 미감을 제공할 수 있기 때문이다.Meanwhile, the fiber means 20 may use any one of a woven fabric and a nonwoven fabric. As shown in FIGS. 1 and 3, the fiber means 20 is needle punched with a web laminated material made of short fibers with a pattern needle. It is preferable to use one pattern face. The reason for this is that the efficiency of sound absorption is improved because it is a plush face, and a pattern and a shape are formed on the surface to provide aesthetics.
첨부도면 도 4 내지 도 5에 도시된 바와 같이 상기 발포 알루미늄판재(10)와 섬유수단(20) 사이에 저융점 단섬유가 혼합되어 이루어진 견면(30)을 더 설치하여 사용할 수 있다. 견면(30)을 일정한 두께를 갖도록 형성시켜 사용하면 흡음율을 향상시킬 수 있으며 상기 견면이 펠팅침으로 니들펀칭된 것을 사용하는 것이 바람직하며 견면을 니들펀칭하는 이유는 소정의 두께로 형성시키기 위함이다.As shown in FIGS. 4 to 5, a low-melting-point short fiber is mixed between the
상기에서와 같이 발포 알루미늄판재(10)와 섬유수단(20) 사이에 저융점 단섬유가 혼합되어 이루어진 견면(30)을 더 설치하여 사용할 수 있다.As described above, the low-melting point short fibers are mixed between the
상기 견면(30)과 발포 알루미늄판재(10)의 부착은 가열수단을 이용하여 열융착하여 부착하며 상기 견면(30)과 패턴견면은 니들펀칭하여 부착한다. The
본 고안의 건축용 내장판넬은 표면에 합성수지재로 이루어진 섬유수단(20)이 있으므로 미감을 제공하도록 함과 동시에 소음을 흡수하면서 단열의 효과를 부가적으로 얻을 수 있으며, 더욱이 발포 알루미늄판재(10)와 섬유수단(20) 사이에 일정한 두께를 갖는 견면(30)을 설치하면 어린아이들이 장난을 치다가 부딪혀도 충격을 흡수하여 신체를 보호하도록 할 수 있는 이점도 있다.The built-in building panel of the present invention has a fiber means (20) made of synthetic resin material on the surface to provide aesthetics while absorbing noise and additionally obtain the effect of heat insulation, and furthermore, the foamed aluminum plate (10) and Installing the
