In general, sandwich panels widely used as interior or exterior materials, partitions or ceiling materials of various buildings such as factories, warehouses, or prefabricated buildings are mainly manufactured by filling styrofoam or urethane or glass fiber or asbestos between a pair of metal plates. This has the advantage of excellent insulation, sound insulation and low cost.

그러나, 종래의 스티로폼이나 우레탄 등을 충전한 샌드위치패널은 화재가 발생하면 열에 의해 쉽게 녹아내리면서 연소하기 때문에 화재를 확산시키게 되었음은 물론 연소시에 유독가스도 발생하기 때문에 막대한 인적 및 물질적인 피해가 초래되게 하는 등의 문제점이 있었다.However, conventional sandwich panels filled with styrofoam or urethane are easily melted and burned by heat when a fire breaks out, which not only spreads the fire but also generates toxic gases during combustion. There was a problem such as causing.

또한, 화재의 발생이 아니더라도 온도가 높을 때에는 열에 의해 스티로폼 등이 녹아서 외부로 유출되어 변형이 초래되기도 하였기 때문에 그 수명이 단축되는 등의 문제점도 있었다.In addition, even if a fire does not occur, when the temperature is high, the styrofoam is melted by heat and leaked to the outside, causing deformation.

그리고, 유리섬유나 석면 등을 충전한 샌드위치패널은 비록 내화성은 있으나 제조 및 시공할 때에는 물론이고 건축물을 해체할 때 각각 발암물질인 유리가루와 석면가루가 방출되는 문제점이 있었다.In addition, although sandwich panels filled with glass fiber or asbestos, although fire-resistant, there was a problem that the carcinogens, as well as asbestos powder, are released when dismantling the building, as well as during manufacturing and construction.

아울러, 스티로폼이나 우레탄 또는 유리섬유나 석면 등을 충전한 샌드위치패널을 해체하여 그대로 폐기 또는 매립하였기 때문에 토양을 오염시켜 생태계를 파괴하게 되는 등의 문제점도 있었다.In addition, since the sandwich panel filled with styrofoam or urethane or glass fiber or asbestos was dismantled or landfilled as it was, there was a problem such as polluting the soil and destroying the ecosystem.

본 발명 실시 예에 따른 샌드위치패널의 제조방법은, 판재를 동일한 크기로 절단하여 표면판재(10)(10')를 제작하는 표면판재제작단계와, 상기 표면판재들 사이의 상하좌우 4면 중 2면 또는 3면을 각각의 측면재(11)로 막아서 2면 또는 1면이 개방되게 패널형틀(20)을 제작하는 패널형틀제작단계와, 단열 및 난연성인 왕겨를 주재로 무독성의 무기질 바인더를 혼합한 후 상기 패널형틀의 내부 크기에 비례하게 성형하여 충전재(40)를 제작하는 충전재제작단계 및 상기 충전재를 개방된 1면 또는 2면 중 어느 1면을 통해 패널형틀의 수용부에 충전한 다음 개방된 면을 측면재(11)로 막아서 봉합제작하여 패널(50)을 완성하는 패널완성단계를 포함하여 구성된다, In the method of manufacturing a sandwich panel according to an embodiment of the present invention, a surface plate manufacturing step of manufacturing the surface plate material 10 and 10 'by cutting the plate material to the same size, and two of the four top, bottom, left and right surfaces between the surface plate material. A panel mold manufacturing step of manufacturing a panel mold 20 so that two or one face is opened by blocking the side or three sides with each side member 11, and a non-toxic inorganic binder is mixed based on heat insulation and flame retardant chaff. Then, the filler is produced in a proportional proportion to the inner size of the panel mold to manufacture the filler 40 and the filler is filled in the receiving portion of the panel mold through one of the opened one or two sides, and then opened. It is configured to include a panel completion step of completing the panel 50 by sealing the side with the side member (11),

표면판재제작단계는, 금속은 물론 난연처리된 합판이나 목재 또는 합성목재나 멜라민수지 등으로 되는 판재들 중 어느 하나의 판재를 선택하여 필요한 크기로 절단하여 표면판재(10)(10')를 제작하는 단계이다.In the surface plate manufacturing step, a surface plate (10, 10 ') is produced by selecting any one of the plates, such as metal, flame retarded plywood, wood, or synthetic wood or melamine resin, and cutting it to the required size. It's a step.

이러한 표면판재제작단계에서 방수처리가 되지 않은 합판이나 목재로 된 판재로 표면판재(10)(10')를 제작하는 경우에는, 건축물의 외장재보다는 내장재나 칸막이 또는 천장재나 실내의 바닥재 등으로 사용하는 것이 바람직하다.In the case of manufacturing the surface plate (10) (10 ') of a plywood or wood plate that is not waterproof in the surface plate manufacturing step, it is used as interior materials, partitions or ceiling materials or indoor floor materials, rather than exterior materials of buildings. It is preferable.

패널형틀제작단계는, 표면판재(10)(10')들 사이의 상하좌우 4면 중 2면 또는 3면을 각각의 측면재(11)로 막아서 봉합하여 2면 또는 1면은 개방되고 내부가 수용부인 육면체로 되게 패널형틀(20)을 제작하는 단계이다.In the panel frame manufacturing step, two or three surfaces of the top, bottom, left, and right surfaces between the surface plates 10 and 10 'are blocked by each side member 11, and the two sides or one side are opened and the inside is closed. It is a step of producing a panel frame 20 to be a cube hexahedron.

상기 패널형틀제작단계에서 사용하는 각 측면재(11)들은 그 폭을 표면판재(10)(10')들 사이의 간격에 비례하는 크기로 되게 하며, 상기 표면판재가 금속인 경우에는 측면재도 금속으로 된 것을 사용하고, 표면판재가 합판이나 목재를 사용하여 된 판재인 경우에 측면재는 목재 또는 합성목재로 된 각목을 사용하는 것이 바람직하다.Each side member 11 used in the panel frame manufacturing step has a width proportional to the distance between the surface plate members 10 and 10 ', and when the surface plate member is metal, the side member member is also made of metal. In the case where the surface plate is made of plywood or wood, the side material is preferably wood or synthetic wood.

아울러, 패널형틀(20)을 금속판재로 제작할 때에는 표면판재(10)(10')와 각 측면재(11)들의 각 접합하는 면을 스폿용접이나 나사못 등으로 부착하면 되고, 합판이나 목재 또는 합성목재로 제작할 때에는 접착제나 나사못 등으로 부착하면 된다.In addition, when the panel frame 20 is made of a metal sheet, the surface joining surfaces of the surface plates 10, 10 'and each side member 11 may be attached by spot welding, screws, or the like. When manufacturing from wood, you can attach it with adhesive or screw.

충전재제작단계는, 먼저 주재인 왕겨에 무기질 바인더를 혼합한 다음 금형에 투입하고 가압하여 패널형틀(20)의 내부크기에 비례하는 크기를 갖는 육면체로 되게 충전재(40)를 성형제작하는 단계이다.The filler manufacturing step is a step of forming the filler 40 into a hexahedron having a size proportional to the internal size of the panel mold 20 by mixing an inorganic binder to the chaff, which is the main material, and then putting it in a mold and pressing the mold.

이렇게 성형제작되는 충전재(40)의 주재인 왕겨는 무방부제로서 단열 및 난연성이 우수하고 인체에 해를 끼치지 않는 친환경소재이며, 아울러 무기질 바인더는 무독성과 내열성인 소재이다.The chaff which is the main material of the filler 40 to be manufactured is a non-preservative and has excellent heat insulation and flame retardancy and does not harm the human body, and the inorganic binder is a non-toxic and heat-resistant material.

따라서, 충전재(40)를 제작 및 시공할 때는 물론이고 샌드위치패널을 설치사용한 후 해체하여 그대로 폐기하여도 발암물질이 방출되거나 토양 또는 자연환경을 오염시키지 않게 되는 특징이 있다.Therefore, when manufacturing and constructing the filling material 40, as well as dismantling and then dismantling the sandwich panel after installation, there is a feature that does not emit carcinogens or pollute the soil or natural environment.

또한, 충전재(40)는, 주재인 왕겨에 중량이 가볍고 다공성인 제올라이트 등과 같은 화산암을 적정한 크기로 분쇄하여서 된 암석입자와 무독성이며 내열성인 무기질 바인더를 투입혼합한 다음 금형에 주입하고 성형하여 패널형틀(20)의 내부의 수용부에 비례하는 크기를 갖는 육면체로 되게 성형제작하여도 된다.In addition, the filler 40 is mixed with rock particles, which are obtained by crushing volcanic rock such as light weight and porous zeolite to an appropriate size, and a non-toxic and heat-resistant inorganic binder. You may shape | mold and make it into a hexahedron which has the magnitude | size proportional to the accommodating part inside (20).

이렇게 제작되는 충전재(40)는 왕겨에 암석입자가 혼합되어 있기 때문에 그 강도가 더욱 강화되어 쉽게 변형 또는 손상되는 현상이 발생하지 않게 됨은 물론 수명단축이 방지되는 특징이 있다.Since the filler 40 produced in this way is mixed with rock particles in the rice husk, its strength is further strengthened so that the phenomenon of being easily deformed or damaged does not occur, as well as shortening of life.

패널완성단계는, 충전재(40)를 개방된 1면 또는 2면 중 어느 한 면을 통해 패널형틀(20)의 수용부에 충전한 다음 개방된 면을 측면재(11)로 막아서 봉합하여 완성된 패널(50)을 제공하게 되는 단계이다.The panel completion step is completed by filling the filler 40 in the receiving portion of the panel mold 20 through either one or two open surfaces, and then closing the open surface with a side member 11 and sealing the finished material. In this step, the panel 50 is provided.

이러한 패널완성단계에서, 패널형틀(20)의 2면이 개방되어 있는 경우에는 그 중 어느 한 면으로 충전재(40)를 삽입한 다음 2면을 각각의 측면재(11)로 막아서 봉합하면 된다.In the panel completion step, when the two sides of the panel mold 20 are open, the filler 40 may be inserted into any one of the panels, and then the two sides may be closed by sealing the respective side members 11.

한편, 충전재(40)는 수용부(12)에 비례하는 크기로 제작되는 것이므로 상기 수용부에 그대로 삽입하여도 되고, 외면에 접착제를 적절하게 도포하여 충전함으로써 패널형틀(50)의 내면에 부착되어 한 몸체와 같이 되도록 하는 것도 바람직하다.On the other hand, since the filler 40 is manufactured to have a size proportional to the accommodating part 12, the filler 40 may be inserted into the accommodating part as it is, and is adhered to the inner surface of the panel mold 50 by appropriately applying and filling an adhesive on the outer surface. It is also desirable to be like a body.

또한, 충전재(40)는 반드시 내부의 수용부에 비례하는 크기의 단 일체로 되게 제작하여야 하는 것은 아니며, 수개로 분할되게 제작하여 충전하여도 되는 것임은 물론이다.In addition, the filler 40 is not necessarily to be made of a single unit of a size proportional to the inner receiving portion, it is of course that the filling may be made to be divided into several.
