In manufacturing the used panel, by tightly weaving the pillar chamber in the form of a checkerboard so that an air film is formed between the upper layer and the lower layer, a resin layer is formed on the outer surface thereof, so as to soundproof and insulate the fiberglass panel. The present invention relates to a fiber glass panel having a multi-layered structure which is very excellent in effect and prevents the fiber glass from being easily deformed even after long-term use, and can reliably block leakage.
일반적으로 화이버 글라스 판넬은 유리섬유와 같은 가벼운 재질로 제작되며, 내열성, 내화성, 방수성, 방음성등이 우수하여 각종 산업분야에서 이를 효과적으로 이용하고자 끊임 없는 연구개발이 진행되고 있는 실정이다.In general, fiberglass panels are made of light materials such as fiberglass, and are excellent in heat resistance, fire resistance, water resistance, soundproofing, and the like, and are constantly being researched and developed to effectively use them in various industrial fields.
특히, 특수차량의 컨테이너 박스(box)나 자동차, 비행기등과 같이 자체 동력으로 움직일 수 있는 장치들은 외부의 충격을 견디기 위해 그 외부 판넬을 강도가 높은 강판을 사용하여 제작되기 때문에 점차 대형화되는 추세에서 상기 자동차와 비행기등은 자체 하중을 감당하기가 어려워지게 됨으로써, 경량의 고강도를 유지할 수 있는 재질의 판넬이 시급히 요구되고 있는 실정이다.In particular, devices that can move on their own power, such as container boxes of special vehicles, automobiles, airplanes, etc., are gradually becoming larger because the outer panels are made of high-strength steel to withstand external shocks. Cars and airplanes are difficult to bear its own load, the situation is urgently required a panel made of a material capable of maintaining light weight and high strength.
그러나 종래에 제공되고 있는 경량재질의 판넬은 모두 고가의 합금재로서, 제조단가의 상승하게 되어 이에 따른 사용자의 경제적인 부담감이 가중되는 문제점이 있었다.However, conventionally provided lightweight panels are all expensive alloy materials, the manufacturing cost is increased, thereby increasing the economic burden of the user.
따라서 근래에는 상기와 같은 문제점들을 해소하고자 강성의 가벼운 재질로되며 가격이 저렴한 화이버 글라스 판넬이 발명된 바 있는데,Therefore, recently, in order to solve the above problems, a fiberglass panel made of a rigid light material and low cost has been invented.
도 4 및 도 5는 종래에 사용되고 있는 화이버 글라스 판넬을 보여주는 것으로서,4 and 5 show a fiber glass panel used in the prior art,
먼저 도 4에서는 단층식으로 제작된 F.R.P 화이버 글라스(10')를 다수개 적층하여 구성된 화이버 글라스 판넬(1')을 보여준다.First, FIG. 4 shows a fiber glass panel 1 'configured by stacking a plurality of F.R.P fiber glass 10' manufactured in a single layer.
그러나 상기 화이버 글라스 판넬(1')은 다수개의 화이버 글라스(10')를 적층하여 제작되기 때문에 매우 중량체로서 상기한 문제점을 해소하기에는 적합하지 못하게 되는 문제점이 있었다.However, since the fiber glass panel 1 'is manufactured by stacking a plurality of fiber glass 10', there is a problem that the fiber glass panel 1 'is not suitable to solve the above problem as a very heavy body.
또한 도 5에서는 상층(14")과 하층(16")사이에 다수의 연결 기둥실(12")이 등간격으로 형성되도록 직조된 유리섬유 외면에 수지재를 도포하여 경화시킨 화이버 글라스 판넬(1")을 보여준다.In addition, in FIG. 5, the fiber glass panel (1) is formed by applying a resin material to the outer surface of the glass fiber woven so that a plurality of connecting pillar chambers 12 "are formed at equal intervals between the upper layer 14" and the lower layer 16 ". ").
그러나 상기 화이버 글라스 판넬(1")은 상기 상층(14")과 하층(16")사이에 형성되는 기둥실(12")이 일정간격을 유지한 채로 듬성듬성하게 직조되어 내부에 공간부(18")가 형성되기 때문에, 상기 화이버 글라스 판넬(1")의 외부 충격에 대한 강성이 저하되고, 또한 판넬 제작에 따른 두께에 제한을 받게 되어 차량이나 비행기등의 판넬로 사용하기에는 적합하지 못하게 되며 상기 공간부(18")가 비교적 간격이 넓게 형성됨에 따라 상기 화이버 글라스 판넬(1")의 방음 및 단열효과가 떨어지게 되는 문제점이 있었다.However, the fiber glass panel 1 "is slitly woven with the pillar chamber 12" formed between the upper layer 14 "and the lower layer 16" at regular intervals, and has a space 18 therein. ") Is formed, the rigidity to the external impact of the fiber glass panel 1" is lowered, and also limited to the thickness according to the panel manufacturing, which is not suitable for use in panels of vehicles or airplanes, As the space portion 18 ″ is relatively wider, there is a problem that the sound insulation and insulation effect of the fiber glass panel 1 ″ are deteriorated.

먼저 도 1내지 도 2에 도시된 바와 같이 다수의 연결 기둥실들(12)에 의해상층(14)과 하층(16)의 복층 구조를 갖도록 직조된 화이버 글라스(10)의 외면에 수지재를 도포한 후, 이를 경화시켜서 제작되는 화이버 글라스 판넬(1)에 있어서,First, as shown in FIGS. 1 to 2, a resin material is applied to the outer surface of the fiberglass 10 woven to have a multi-layer structure of the upper layer 14 and the lower layer 16 by a plurality of connecting pillar chambers 12. In the fiber glass panel (1) produced by hardening this,
상기 기둥실(12)들은 두개의 인접한 기둥실(12) 하단부들 사이의 간격이 상단부들 사이의 간격보다 넓게 배열되고, 그에 일측으로 인접한 기둥실(12)은 이와 반대로 배열되는 형태로 직조되며, 상기 기둥실(12)들의 전방이나 후방으로 인접하여 직조되는 기둥실(12)들은 상기와 같은 동일한 배열로 직조되되, 상기 각 기둥실(12)들은 서로 엇갈리는 형태로 직조되어 이루어진다.The pillar chambers 12 are woven in such a manner that the spacing between the lower ends of two adjacent pillar chambers 12 is wider than the gap between the upper ends, and the pillar chambers 12 adjacent to one side thereof are arranged in the opposite direction. The pillar chambers 12 which are woven adjacent to the front or rear of the pillar chambers 12 are woven in the same arrangement as described above, but the pillar chambers 12 are woven in a staggered form.
이때 상기 상층(14)과 하층(16)사이에서 엇갈리게 직조되는 다수의 기둥실(12)들의 사이에는 에어(air)막(18)이 형성되어 이루어진다.At this time, an air film 18 is formed between the plurality of pillar chambers 12 interweaved between the upper layer 14 and the lower layer 16.
이와 같이 서로 엇갈리는 형태로 촘촘하게 배열되어 직조되는 다수의 기둥실(12)들에 의해 상층(14)과 하층(16)의 복층 구조를 갖도록 직조되는 화이버 글라스(10)는 그 외면에 수지재를 도포하여 수지층(20)이 형성되도록 이를 경화시켜 화이버 글라스 판넬(1)을 제작하게 됨으로써, 상기 화이버 글라스 판넬(1)의 외부 충격에 대한 강도가 매우 우수하게 된다.The fiberglass 10 woven to have a multi-layer structure of the upper layer 14 and the lower layer 16 by a plurality of pillar chambers 12 that are arranged and interwoven in a staggered form as described above is coated with a resin material on the outer surface thereof. By hardening it so that the resin layer 20 is formed, the fiber glass panel 1 is manufactured, and thus the strength against the external impact of the fiber glass panel 1 is very excellent.
아울러 상기 상층(14)과 하층(16)사이에서 서로 엇갈리게 직조되는 다수의 기둥실(12)들에 의해 형성된 에어(air)막(18)에 의해 상기 화이버 글라스 판넬(1)의 방음 및 단열의 효과가 더욱 우수하게 됨은 물론 이와 같이 제작된 화이버 글라스 판넬(1)은 누수의 차단효과가 탁월하며 장기간 사용시에도 쉽게 변형되거나 파손되는 것이 방지되어 화이버 글라스 판넬(1)의 사용에 따른 사용자의 신뢰도가 우수하게 제공되는 것이다.In addition, the sound insulation and thermal insulation of the fiber glass panel 1 by the air film 18 formed by a plurality of pillar chambers 12 interweaved between the upper layer 14 and the lower layer 16. In addition, the fiber glass panel 1 manufactured as described above is excellent in blocking the leakage of water and is easily prevented from being deformed or broken even after long-term use, thereby increasing the reliability of the user according to the use of the fiber glass panel 1. It is excellently provided.
따라서 상기와 같이 경량이면서 강성이 우수한 화이버 글라스 판넬(1)을 이용하여 특수차량의 컨테이너 박스(box)나 자동차, 비행기등의 판넬을 제작하여 사용하게 됨으로써, 각종 차량이나 비행기등의 자체 하중을 줄일 수 있게 되고 외부 충격에 대한 충분한 강성을 제공할 수 있게 되므로 대형화가 가능하게 될 뿐만아니라, 상기 화이버 글라스 판넬(1)은 상기 에어(air)막(18)에 의해 내열 및 내화, 방음, 방습, 단열효과가 우수하게 제공되어 보다 넓은 범위에 걸쳐 활용이 가능하게 되는 것이다.Therefore, by using the fiberglass panel 1, which is lightweight and excellent in rigidity as described above, a panel of a special vehicle container box, an automobile, an airplane, etc. is manufactured and used, thereby reducing its own load on various vehicles or airplanes. It is possible to provide a large stiffness against external shocks and to increase the size, as well as the fiber glass panel 1 is heat-resistant and fire-resistant, soundproof, moisture-proof, Excellent insulation effect is provided that can be utilized over a wider range.
이상에서 살펴본 바와 같이 본 발명의 복층 구조를 갖는 화이버 글라스 판넬에 의하면 다수의 연결 기둥실에 의해 상층과 하층의 복층 구조로 직조되는 화이버 글라스에 있어, 상기 기둥실이 서로 엇갈리도록 배열되게 직조하여 줌으로써, 상기 화이버 글라스 판넬의 외부 충격에 대한 강성이 우수하게 제공되어, 보다 두꺼운 판넬의 제작이 가능하게 되고, 장기간 사용시에도 상기 화이버 글라스 판넬이 쉽게 변형되거나 파손되는 것이 방지되며, 상기 상층과 하층사이에 형성된 에어(air)막에 의해 화이버 글라스 판넬의 방음 및 단열효과가 매우 우수하게 됨은 물론 누수를 확실하게 차단할 수 있는 매우 유용한 발명인 것이다.As described above, according to the fiberglass panel having a multi-layer structure of the present invention, in the fiber glass woven into a multi-layer structure of an upper layer and a lower layer by a plurality of connecting pillar chambers, In addition, the rigidity against the external impact of the fiber glass panel is excellent, it is possible to manufacture a thicker panel, the fiber glass panel is prevented from being easily deformed or damaged even in the long-term use, between the upper layer and the lower layer The air film formed is very effective sound insulation and heat insulation effect of the fiber glass panel, as well as a very useful invention that can reliably block leakage.
