Description
본 고안은 샌드위치패널에 관한 것으로서, 보다 상세하게는 제조 설비의 증가를 초래하지 않으면서도, 화재의 염려가 없고 방음 효과가 저하되지 않으며, 열손실이나 결로가 발생되지 않도록 된 샌드위치패널에 관한 것이다.The present invention relates to a sandwich panel, and more particularly, to a sandwich panel, which does not cause an increase in manufacturing equipment, does not cause a risk of fire, and a sound insulation effect does not decrease, and heat loss or condensation does not occur.
일반적으로, 샌드위치 패널은 대략 사각의 내장재의 양면에 금속판을 각각 부착하여 구성되고, 그 양단부에는 상기 금속판으로부터 외측으로 연장된 결합부가 각각 구비되어, 다수개를 연속적으로 연결하였을 때, 어느 하나의 샌드위치패널의 제1 결합부와 이웃한 다른 샌드위치패널의 제2 결합부가 서로 맞물리도록 되어 있다. 이러한 결합부는 서로 끼워 맞춰지도록 상기 금속판의 단부를 얇게 절곡하여 이루어진다. 이때, 상기 충전재는 얇게 절곡되어 이루어진 상기 결합부에 맞추어 그 양단부를 절단할 수 없기 때문에, 그 양단부를 대략 일자로 절단하고, 이 충전재의 양단부와 결합부의 내측면 사이의 공간부에 별도의 우레탄을 발포하여 충전함으로써, 상기 결합부위가 벌어지거나 좁혀지지 않도록 보강하게 된다.In general, a sandwich panel is formed by attaching metal plates to both sides of a substantially rectangular interior material, and both ends thereof are provided with joining portions extending outward from the metal plate, respectively, and any one sandwich is connected continuously. The first engaging portion of the panel and the second engaging portion of another adjacent sandwich panel are engaged with each other. This coupling portion is made by bending the end of the metal plate thinly to be fitted to each other. In this case, since the filler cannot be cut at both ends in accordance with the joint portion formed by being bent thinly, the both ends are cut to approximately a day, and a separate urethane is added to the space between the both ends of the filler and the inner side of the coupling portion. By filling by foaming, the bonding portion is reinforced so as not to be opened or narrowed.
그런데, 상기 샌드위치패널의 양단부 내측에 우레탄을 발포시켜 충전할 경우, 상기 우레탄이 불연성이 아니기 때문에, 화재의 염려가 초래되는 문제점이 있다. 또한, 상기 우레탄을 발포하여 충전하기 위한 별도의 우레탄 발포 설비가 요구되기 때문에, 설비의 증가를 초래하는 문제점이 있다.However, when the urethane is foamed and filled inside both ends of the sandwich panel, since the urethane is not nonflammable, there is a problem that a fire is caused. In addition, since a separate urethane foaming equipment for foaming and filling the urethane is required, there is a problem that causes an increase in the equipment.
이에 따라, 최근에는 상기 결합부의 전후면 금속판을 연결하도록 보강재를 설치하여, 상기 결합부가 좁혀지거나 벌어지지 않도록 된 샌드위치패널이 개발된 바 있다. 그러나, 이러한 샌드위치패널은 충전재의 양단부와 결합부 사이에 공간부가 형성되기 때문에, 이 공간부에 의해 방음이나 차음 효과의 저하가 초래됨은 물론 열손실과 결로가 발생되는 등의 여러 가지 문제점이 있다.Accordingly, recently, a sandwich panel has been developed in which a reinforcing member is installed to connect the front and rear metal plates of the coupling portion so that the coupling portion is not narrowed or opened. However, since the sandwich panel is provided with a space portion between both ends of the filler and the coupling portion, there is a variety of problems such as not only the sound insulation or sound insulation is reduced by the space portion, but also heat loss and condensation.
본 고안은 전술한 바와 같은 문제점에 착안하여 제안된 것으로서, 본 고안의 목적은 제조 설비가 증가되지 않으면서도, 화재의 염려가 없고 방음 효과가 저하되지 않으며, 열손실이나 결로가 발생되지 않도록 된 새로운 구성의 샌드위치패널을 제공하고자 하는 것이다.The present invention has been proposed in view of the above-described problems, and the object of the present invention is to increase the manufacturing facilities without increasing the risk of fire and to reduce the soundproofing effect, and to prevent heat loss or condensation. It is to provide a sandwich panel of the configuration.

상기 충전재(20)는 글래스울과 같은 불연성 재질로 이루어진 것으로, 그 일단부는 상기 제1 결합부(30)의 내측면과 제1 보강재(45)의 오목부(58) 내측면에 밀착되도록 절취된다. 또한, 상기 충전재(20)의 타단부는 제2 결합부(35)의 내측면과제2 보강재(55)의 볼록부(62) 내측면에 밀착되도록 절취된다. 이에 따라, 종래와 같이 상기 충전재(20)의 양단부와 금속판(10, 15)의 내측면 사이에 별도의 우레탄을 발포시켜 충전하지 않더라도, 상기 충전재(20)와 금속판(10, 15) 및 보강재(45, 55) 사이에 공간부가 발생되지 않게 된다.The filler 20 is made of a non-combustible material such as glass wool, and one end thereof is cut to closely contact the inner surface of the first coupling portion 30 and the inner surface of the recess 58 of the first reinforcing material 45. . In addition, the other end of the filler 20 is cut to be in close contact with the inner surface of the second coupling portion 35 and the inner surface of the convex portion 62 of the second reinforcing material (55). Accordingly, the filler 20 and the metal plates 10 and 15 and the reinforcing material may be filled even if the urethane is not filled by foaming urethane between both ends of the filler 20 and the inner surfaces of the metal plates 10 and 15 as in the related art. The space part is not generated between 45 and 55).
따라서, 상기 샌드위치패널은 상기 충전재(20)가 불연성 재질로 이루어지고, 이 충전재(20)의 양단부가 금속판(10, 15)과 보강재(45, 55)의 내측면에 밀착되도록 절취되어, 종래와 같이, 상기 충전재(20)의 양단부와 금속판(10, 15) 사이에 별도의 우레탄을 발포시켜 충전하지 않아도 되므로, 화재의 염려를 초래하지 않는 장점이 있다. 또한, 상기 샌드위치패널은 우레탄을 발포 충전하기 위한 별도의 발포 설비가 요구되지 않기 때문에, 설비의 증가를 방지하는 장점이 있다. 그리고, 상기 충전재(20)가 금속판(10, 15)과 보강재(45, 55)의 내측면에 밀착되어 공간부가 형성되지 않기 때문에, 방음이나 차음 효과의 향상을 기할 수 있음은 물론 열손실과 결로를 방지하는 등의 여러 가지 장점이 있다.Therefore, the sandwich panel is made of the non-combustible material of the filler 20, and both ends of the filler 20 are cut so as to be in close contact with the inner surfaces of the metal plates 10 and 15 and the reinforcing members 45 and 55. Likewise, since the urethane does not have to be foamed and filled between both ends of the filler 20 and the metal plates 10 and 15, there is an advantage of not causing a fire. In addition, the sandwich panel has an advantage of preventing the increase of equipment because a separate foaming equipment for foam filling the urethane is not required. In addition, since the filler 20 is in close contact with the inner surfaces of the metal plates 10 and 15 and the reinforcing members 45 and 55, and no space is formed, it is possible to improve sound insulation and sound insulation, as well as heat loss and condensation. There are many advantages, such as preventing.
한편, 상기 전면 금속판(10)의 일단부에는 외측으로 연장되다가 그 선단이 후방으로 경사지게 절곡되는 연장부(13a)가 구비되어, 다수개의 샌드위치패널을 연결 조립할 때, 도 2에 도시된 바와 같이, 상기 연장부(13a)가 이웃한 샌드위치패널의 전면 금속판(10)의 외측면과 상기 연장부(13a)의 내측면 사이에 볼트수납부(16a)가 형성된다. 이에 따라, 상기 샌드위치패널을 다수개의 지지빔(8a)에 볼트(3)로 체결하여 조립할 때, 이 볼트(3)의 볼트헤드(3a)가 상기 볼트수납부(16a)에 수납되어 외부로 노출되지 않는다. 또한, 이처럼 상기 전면 금속판(10)의 일단부에연장부(13a)가 구비되어, 실질적으로 샌드위치패널의 두께가 기존 제품보다 두꺼워지면서 충전재(20)의 충전 공간이 그만큼 많아지기 때문에, 서로 연결 조립된 샌드위치패널의 결합 부위에서의 방음 및 단열 효과가 기존 제품에 비하여 현저히 높아지게 된다. 또한, 기존 제품에 비하여 충전재(단열재)(20)를 충전하는 작업의 어려움을 해소하고, 별도의 볼트헤드(3a) 공간이 필요함으로 인하여 유발되는 단열 손실을 크게 방지할 수 있다.On the other hand, one end portion of the front metal plate 10 is provided with an extension portion 13a extending outward and bent inclined backwards, when assembling a plurality of sandwich panels, as shown in Figure 2, A bolt accommodating portion 16a is formed between the outer surface of the front metal plate 10 of the sandwich panel where the extension portion 13a is adjacent and the inner surface of the extension portion 13a. Accordingly, when the sandwich panel is fastened and assembled to the plurality of support beams 8a by the bolts 3, the bolt heads 3a of the bolts 3 are accommodated in the bolt storage portions 16a and exposed to the outside. It doesn't work. In addition, the extension portion 13a is provided at one end of the front metal plate 10, and the thickness of the sandwich panel is substantially greater than that of the existing product, so that the filling space of the filler 20 increases, so that the assembly is connected to each other. The sound insulation and insulation effect at the joint of the sandwich panel is significantly higher than that of the existing product. In addition, as compared to the existing product to solve the difficulty of filling the filler (insulation material) 20, it is possible to greatly prevent the insulation loss caused by the need for a separate bolt head (3a) space.
이상에서와 같이 본 고안에 의하면, 상기 샌드위치패널은 충전재의 양단부와 금속판 사이에 별도의 우레탄을 발포시켜 충전하지 않아도 되므로, 화재의 염려를 초래하지 않고, 우레탄 발포 설비가 요구되지 않아 설비의 증가를 방지하고, 상기 충전재가 금속판의 내측면에 밀착되기 때문에, 방음이나 차음 효과의 향상 및 열손실과 결로의 방지를 기할 수 있는 장점이 있다.As described above, according to the present invention, since the sandwich panel does not have to be filled by foaming urethane between the both ends of the filler and the metal plate, it does not cause fire and does not require urethane foam equipment, thereby increasing the equipment. And since the filler is in close contact with the inner surface of the metal plate, there is an advantage that can improve the sound insulation and sound insulation effect and prevent heat loss and condensation.
