본 발명은 디프 드로잉(deep drawing) 가공에 의한 건축물 내외장용 금속 샌드위치 패널의 디프 드로잉 가공심재와 그 심재를 이용한 건축물 내외장용 샌드위치 패널에 관한 것으로서, 특히 드로잉 다이(drawing die)에서 금속판을 디프 드로잉 가공하여 금속판에 가로와 세로 방향의 일정한 간격으로 바닥이 붙은 원통이나 각통이 다수개 형성되게 하여서된 디프 드로잉 가공에 의한 건축물 내외장용 금속 샌드위치 패널의 디프 드로잉 가공심재와 그 심재를 이용한 샌드위치 패널에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deep drawing processing core material of a metal sandwich panel for building interior and exterior by deep drawing processing, and a sandwich panel for building interior and exterior using the core material, in particular, a deep drawing processing of a metal plate in a drawing die. To a deep drawing core material and a sandwich panel using the core material of a metal sandwich panel for building interior and exterior by deep drawing processing, in which a plurality of cylinders or square cylinders having bottoms are formed on a metal plate at regular intervals in a horizontal and vertical direction. .

현재까지 개발된 건축물 내외장용 샌드위치 패널(이하 샌드위치 패널이라고 약칭함)은 일반적으로 발포성이나 비발포성 폴리에틸렌과 같은 플라스틱 시트를 심재로 하거나, 하니컴형 금속을 코어로 하거나, 도5에 도시된 바와 같은 코러게이션형(물결주름형) 금속을 코어(5)로 하여 그 코어(5)를 중심으로 그 상하에 접착제층(3)(3')을 적층하고, 다시 그 상하에 금속이나 비금속판(4)(4')을 적층한 후 열압착하여 샌드위치 패널을 제조하여 왔으나, 상기한 플라스틱 시트를 심재(코어)로 한 샌드위치 패널의 경우에는 플라스틱 심재가 화기에 약하여 건축물 화재시 융해 및 연소되면서 유독가스가 발생하는등 화재에 취약하여 건축자재의 불연성을 강조하는 현실에 비추어볼때 불연성 자재로서는 부적절하며 상기한 하니컴형 코어나 물결주름형 코어를 사용하는 샌드위치 패널의 경우들에는 건축물 내외벽의 굴곡부나 코너부의 시공시에 패널의 일정부위를 가로방향이나 세로방향으로 V자형 등으로 그루브(groove;홈)를 내는 홈 형성작업(그루빙;grooving)을 한 후 그 그루브를 중심으로 샌드위치 패널을 절곡한 다음 시공해야 하는 단계에서 샌드위치 패널을 구성하고 있는 하니컴형이나 물결주름형의 심재들은 그 구조상 결합으로 인하여 패널을 절곡하기 위한 부위의 그루빙 작업이 용이하지 못한 결점이 있었다.Sandwich panels for building interior and exterior (abbreviated as sandwich panels) developed so far are generally made of a plastic sheet such as foam or non-foamable polyethylene as a core, a honeycomb metal as a core, or a corrugation as shown in FIG. 5. With the core (corrugated) metal as the core 5, the adhesive layers 3 and 3 'are laminated on the upper and lower sides of the core 5, and the metal or the nonmetal plate 4 above and below. Sandwich panels have been manufactured by laminating (4 ') and then thermally compressing them. However, in the case of the sandwich panel having the core as the core (plastic core), the plastic core is weak in fire and toxic gas is melted and burned in the event of building fire. In view of the fact that it is vulnerable to fire such as occurrence and emphasizes the incombustibility of building materials, it is inadequate as a non-combustible material. In the case of sandwich panels, grooves are formed to form grooves in a V-shape or the like in a horizontal direction or a vertical direction when a curved part or a corner part of a building interior and exterior walls is constructed. After the sandwich panel is bent around the groove, the honeycomb or corrugated cores constituting the sandwich panel are required to be grooved at the site to bend the panel due to the structural combination. There was a fault that was not easy.

이를테면, 하니컴형 코어(5)를 내장한 샌드위치 패널의 경우에는 상하 금속이나 비금속판재(4)(4')와 코어(5)가 선형으로 접착되게되어 접착력이 기준이하로 부적절하게 접합되기 때문에 V자형 커팅 등 그루빙작업을 하게되면 심재(5)와 상하 판재(4)(4')의 접착부위가 손상되거나 박리되므로 샌드위치 패널의 기능이 저하되게 되며, 뿐만 아니라 하니컴형 구조가 연속적으로 형성되어 있으므로 평판의 절단시보다는 절단작업이 용이하지 못하여 절곡을 위한 그루빙 작업이 용이하지 못한 결함이 있었고 물결주름형 코어를 내장한 샌드위치 패널의 경우는, 도5에 도시된 바와 같이, 코어(5)의 굴곡부위와 상하 판재(4)(4')가 선형으로 접착되어 있기 때문에 이 역시 선형 접착에 의한 접착력이 약하므로 절곡을 위한 그루브(groove)(홈) 형성작업(V자형 커팅 등)시에 코어(5)와 판재(4)(4')의 접착부위가 박리되기 쉽고 따라서 패널의 기능이 손상되게 되는 결점이 있는가 하면, 그루빙 작업 자체에 있어서도 코어의 형태가 물결주름으로 구성되어 있어서 주름방향으로 절곡홈(8')을 형성(그루빙)하고자 할때에 그 절곡한 부위가 그 물결주름 심재의 굴곡진 홈(10)과 일치되게 되는 경우에는 그 물결주름 심재 자체의 굴곡된 홈(10)을 따라 판재를 절곡하여야 하므로 그루빙작업시 심재(5)에의한 상하 판재(4)(4')와 지지기능이 급격히 저하되어 절곡된 외부면의 절곡선이 매끄럽게 마무리되기가 어렵거나, 절곡 자체가 어렵게 되고, 그 절곡할 부위가 주름의 언덕진(돌출된) 부위와 일부 일치시에는 그 부위를 그루빙하기 위해 절개시에는 그 주름부위(11) 전체가 절단되게 되어 패널 절곡부가 매끄럽지 못하고 따라서 절곡된 외표면이 미려하지 못한 결점이 있었다.For example, in the case of a sandwich panel in which a honeycomb-shaped core 5 is embedded, the upper and lower metal or nonmetal plate 4 and 4 'and the core 5 are linearly bonded to each other so that the adhesive force is improperly bonded below the standard. When grooving is performed, the cutting part of the core 5 and the upper and lower plate members 4 and 4 'are damaged or peeled off, so that the function of the sandwich panel is degraded, and the honeycomb structure is continuously formed. Therefore, in the case of a sandwich panel in which the grooving operation for bending is not easy because the cutting operation is not easy than the cutting of the flat plate, and the corrugated core is incorporated, as shown in FIG. 5, the core 5 Since the bent portion of the upper and lower plates (4) (4 ') are linearly bonded, this also has a weak adhesive force due to linear bonding, so when forming a groove (groove) for bending (V-shaped cutting, etc.) The adhesive part of the core 5 and the board members 4 and 4 'is easily peeled off, and thus the function of the panel is impaired. In addition, even in the grooving operation itself, the shape of the core is composed of wave wrinkles. When the bent portion is to be formed (groove) in the direction of the bending groove (8 ') to match the curved groove 10 of the corrugated core material, the curved groove of the corrugated core material itself ( 10) Since the plate should be bent along the upper and lower plate 4 and 4 'by the core 5 during the grooving operation, the support function is sharply lowered and it is difficult to smoothly finish the bending line of the bent outer surface. The bending itself becomes difficult, and when the portion to be bent coincides with the raised (protruded) portion of the wrinkle, the entire wrinkle portion 11 is cut at the time of incision to cut the portion so that the panel bent portion is not smooth. Thus bent out If this had failed elegant drawbacks.

따라서 물결주름형 코어로 된 샌드위치 패널은 가로, 세로방향으로 절곡이 자유롭지 못하고 단지 물결주름과 수직방향으로만 그루브(8)를 완벽하게 형성하여 패널의 절곡이 가능하게 되는 결점이 있게 된다.Therefore, the sandwich panel of the corrugated core is not free to be bent horizontally and vertically, but has a drawback in that the panel 8 can be bent by perfectly forming the groove 8 only in the vertical direction with the corrugation.

본 발명은 상기한 바와 같은 종래의 하니컴 코어나 물결주름형 코어를 이용한 샌드위치 패널에서 패널을 절곡시에 절곡부위의 그루빙이 원활치 못한 결점을 해소하여 샌드위치 패널을 건축물 내외장용으로 시공시에, 특히 건축물 굴곡부에 절곡시킨 샌드위치 패널을 시공시에 샌드위치 패널의 적정부위를 그루빙하여 가로나 세로 어느 방향으로든 절곡하기가 쉽도록 하기 위하여 알루미늄판, 석도강판, 아연도강판, 스테인레스판과 같은 금속판을 드로잉 다이(drawing die)에서 디프 드로잉 가공(deep drawing)하여 바닥이 붙은(막힌) 원통형이나 삼각형 및 4각형을 비롯한 다각형의 통이 금속판 아래에 형성되도록 샌드위치 패널용 심재(core)를 얻고 그 심재(core)를 사용하여 통상의 샌드위치 패널 제조공정에 의해 제조되는 샌드위치 패널을 제공코저 하는 것으로서 이를 첨부된 도면들을 참조하여 상세히 설명하면 다음과 같다.The present invention eliminates the drawbacks of the grooving of the bent portion when bending the panel in the sandwich panel using the conventional honeycomb core or corrugated core as described above, especially when the sandwich panel is used for interior and exterior of buildings In order to make it easy to bend in any direction horizontally or vertically by grooving the appropriate part of the sandwich panel when constructing the sandwich panel bent at the curved part of the building, metal plates such as aluminum plate, steel plate, galvanized steel sheet, and stainless plate are drawn. Deep drawing in a die is used to obtain cores for sandwich panels so that bottomed (clogged) cylinders or polygonal cylinders, including triangles and quadrilaterals, are formed underneath the metal plate and cores To provide a sandwich panel manufactured by a conventional sandwich panel manufacturing process using If this description with reference to the accompanying drawings in detail as follows.

하니컴형이나 코러게이션(물결주름:corrugation)형 심재(core) 중에서 선택된 어느 한가지의 금속으로 된 심재(5)의 상하면에 상하 접착제층(3)(3')과 그 위의 상하 금속이나 비금속판재(4)(4')를 차례로 적층한 후 열압착하여서 되는 건축물 내외장용의 샌드위치 패널에 있어서,Upper and lower adhesive layers (3) (3 ') on the upper and lower surfaces of the core 5 of any one metal selected from a honeycomb or corrugation core. In the sandwich panel for interior and exterior of a building which is laminated by (4) (4 ') one by one and thermo-compressed,
