본 발명은 내화성 샌드위치패널에 관한 것으로서, 보다 상세하게는 연결부위의 난화성이 강화되어 화재규모와 피해를 줄일 수 있으며, 조립도 편리한 새로운 구조의 내화성 샌드위치패널에 관한 것이다. The present invention relates to a fire-resistant sandwich panel, and more particularly, to a fire-resistant sandwich panel of a new structure that can be reduced fire scale and damage by strengthening the fire resistance of the connection portion, and also easy to assemble.

도 1에 도시된 바와 같이, 샌드위치패널은 글래스울이나 스티로폼 또는 우레탄과 같은 심재(1)의 전후면에 한쌍의 금속판(2,3)이 부착되어 이루어진다. 이러한 샌드위치패널은 다수개 연결조립될 수 있도록 양측 단부에는 각각 암결합부(4)와 숫결합부(5)가 형성된다. 그런데 샌드위치패널은 암결합부(4)와 숫결합부(5)가 서로 정합되도록 정교하게 성형되지 못하므로 샌드위치패널을 연결조립하면 샌드위치패널의 연결부에는 틈이 발생된다. As shown in FIG. 1, a sandwich panel is formed by attaching a pair of metal plates 2 and 3 to front and rear surfaces of a core material 1 such as glass wool, styrofoam, or urethane. The sandwich panel has a female coupling portion 4 and a male coupling portion 5 are formed at both ends thereof so that a plurality of sandwich panels can be assembled. By the way, the sandwich panel is not precisely molded so that the female coupling portion 4 and the male coupling portion 5 are matched with each other, so when the sandwich panel is connected and assembled, a gap is generated in the connection portion of the sandwich panel.

한편, 화재시에는 화염 및 유독가스가 퍼지는 것이 방지되어야 하며, 이에 따라 인명 및 재산상의 피해도 줄일 수 있다. 그런데 샌드위치패널이 사용된 건축물에 화재가 발생된 경우에는, 전술한 바와 같이, 샌드위치패널의 연결부에 발생된 틈을 통해 화염 및 유독가스가 이웃 공간으로 전달되며, 연결부의 틈으로 침투되는 화염에 의해 샌드위치패널, 특히 심재가 연소되기도 한다. On the other hand, in case of fire, flames and toxic gases should be prevented from spreading, thereby reducing the risk of human and property damage. However, when a fire occurs in a building using a sandwich panel, as described above, the flame and toxic gas are transferred to the neighboring space through the gap generated in the connection portion of the sandwich panel, and the flame penetrates into the gap of the connection portion. Sandwich panels, especially core materials, may burn.

따라서 샌드위치패널의 연결조립시에는 샌드위치패널의 연결부위를 강화하기 위해 조립되는 샌드위치패널의 암결합부(4)와 숫결합부(5) 사이에 세라쿨(상표명) 을 삽입하여 패널을 연결조립한다. 그런데 시공현장에서 작업자가 일일이 세라쿨을 삽입하여 패널을 연결시켜야 하므로 작업이 번거롭고 작업시간도 많이 소요된다. 뿐만 아니라 세라쿨이 고가이므로 건축물의 시공 코스트도 상승된다.Therefore, when assembling the sandwich panel, the panel is assembled by inserting Cerakul (trade name) between the female coupling portion 4 and the male coupling portion 5 of the sandwich panel assembled to reinforce the connection portion of the sandwich panel. . However, in the construction site, the worker has to insert the ceraculus one by one to connect the panel, which is cumbersome and time consuming. In addition, because the cerakul is expensive, the construction cost of the building also increases.

본 발명은 전술한 바와 같은 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 패널의 연결부를 통해 화염 및 유독가스가 퍼지는 것이 방지되고 패널의 내화성도 향상되므로 화재에 의한 피해를 줄일 수 있으며, 연결시공시 작업현장에서 패널 사이에 별도의 난연재를 삽입하지 않아도 되므로 작업성이 우수하고 시공도 편리한 새로운 구조의 내화성 샌드위치패널을 제공하고자 하는 것이다.The present invention is to solve the above problems, an object of the present invention is to prevent the spread of flame and toxic gas through the connection portion of the panel and to improve the fire resistance of the panel can reduce the damage caused by fire, connection construction It is to provide a fire-resistant sandwich panel with a new structure, which is excellent in workability and convenient in construction since it is not necessary to insert a separate flame retardant material between panels at the work site.

본 발명에 따르면, 심재(10)의 전후면에 한쌍의 금속판(20,30)이 부착되어 이루어지며, 양측 단부에는 각각 암결합부(40)와 숫결합부(50)가 형성되어 다수개 연결시공되는 샌드위치패널에 있어서, 상기 암결합부(40)와 숫결합부(50) 중 적어도 하나에는 열에 의해 발포되는 난연재(60)가 도포된 것을 특징으로 하는 내화성 샌드위치패널이 제공된다.According to the present invention, a pair of metal plates 20 and 30 are attached to the front and rear surfaces of the core material 10, and female coupling parts 40 and male coupling parts 50 are formed at both ends, respectively, so that a plurality of connections are made. In the sandwich panel to be constructed, at least one of the female coupling portion 40 and the male coupling portion 50 is provided with a fire-resistant sandwich panel, characterized in that the flame-retardant material 60 is coated with heat.

본 발명의 다른 특징에 따르면, 상기 열에 의해 발포되는 난연재(60)는 물유리인 것을 특징으로 하는 내화성 샌드위치패널이 제공된다. According to another feature of the invention, the flame retardant material 60 is foamed by the heat is provided with a fire-resistant sandwich panel, characterized in that the water glass.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. 2 and 3 are cross-sectional views showing an embodiment of the present invention. As shown in the present invention, the sandwich panel is formed by attaching the metal plates 20 and 30 to the front and rear surfaces of the core 10, and both ends thereof have a female coupling portion 40 and a male coupling portion 50 having a shape corresponding to each other. Is formed. The female coupling portion 40 is made of the front and rear metal plates 20 and 30 protrude outward from the core material 10, the male coupling portion 50 is inserted into the female coupling portion 40 is fastened from the outside Interconnected by bolts.

한편, 상기 암결합부(40)의 내측면에는 열에 의해 발포되는 난연재(60)가 도포된다. 열에 의해 발포되는 난연재로는 물유리, 탄산수소나트륨, 수산화마그네슘, 수산화알루미늄 등이 사용된다. 이들은 고온(대략 150℃ 이상)으로 가열되면 결정수가 증발되어 발포되거나 또는 성분이 분해되어 발생되는 수분이나 가스에 의해 발포되어 부피가 팽창된다. 바람직하게는 물유리가 사용되는데, 물유리 중에서도 액상의 규산나트륨(Na20ㆍnSiO2ㆍxH2O)이 사용된다. On the other hand, the flame-retardant material 60 is foamed by the heat is applied to the inner surface of the female coupling portion 40. As the flame retardant foamed by heat, water glass, sodium bicarbonate, magnesium hydroxide, aluminum hydroxide and the like are used. When heated to a high temperature (about 150 DEG C or more), the crystal water evaporates and foams, or foams are expanded by moisture or gas generated by decomposition of the components and expands in volume. Preferably, water glass is used, and liquid sodium silicate (Na 2 0 nSiO 2 xH 2 O) is also used among the water glass.

The present invention constituted as described above is used when building a wall or a roof of a building, which is assembled in plural so that the female coupling portion 40 and the male coupling portion 50 of the neighboring panel are connected to each other. When is raised, the flame retardant foams and the volume expands. And as the flame retardant is expanded, the gap A generated in the connection portion of the sandwich panel is filled. Thus, the gap A generated in the connection portion of the sandwich panel is filled. Spreading is prevented. The flame retardant also improves the flame retardancy of the sandwich panel.

한편, 필요에 따라서는 암결합부(40) 뿐만 아니라 숫결합부(50)에도 상기 열에 의해 발포되는 난연재(60)가 도포될 수 있으며, 양측 결합부(40,50)에 모두 난연재(60)가 도포될 수도 있다. 또한, 도시된 암결합부(40) 및 숫결합부(50)의 형상은 일례를 보인 것에 불과하며, 암, 숫결합부(40,50)의 형상은 다양하게 변형될 수 있다. Meanwhile, if necessary, the flame retardant 60 foamed by the heat may be applied to the female coupling part 40 as well as the male coupling part 50, and both flame retardant materials 60 may be applied to both coupling parts 40 and 50. May be applied. In addition, the shape of the female coupling portion 40 and the male coupling portion 50 shown is just an example, the shape of the female, male coupling portion 40, 50 may be variously modified.

이상에서와 같이 본 발명에 의하면, 패널의 암결합부(40) 또는 숫결합부(50)에 열에 의해 발포되는 난연재(60)가 도포되어 화재시 발생되는 열에 의해 상기 난연재(60)가 팽창되어 패널의 연결부에 발생된 틈(A)이 자동으로 메워지므로, 패널의 연결부를 통해 화염 및 유독가스가 퍼지는 것이 방지되며, 패널자체의 내화성도 향상되어 화재에 의한 피해를 줄일 수 있다. 또한, 본 발명에 따르면, 패널의 단부에 난연재(60)가 도포되어 있으므로, 종래와 같이 패널의 연결조립시 패널 사이에 세라쿨을 삽입하여 조립하는 번거로운 작업을 하지 않아도 되므로 패널의 연결작업이 편리하고 작업성이 우수하다. As described above, according to the present invention, the flame retardant 60 is foamed by heat to the female coupling portion 40 or the male coupling portion 50 of the panel and the flame retardant 60 is expanded by the heat generated in the fire. Since the gap A generated in the connection portion of the panel is automatically filled, the flame and toxic gas is prevented from spreading through the connection portion of the panel, and the fire resistance of the panel itself is also improved to reduce the damage caused by the fire. In addition, according to the present invention, since the flame-retardant material 60 is applied to the end of the panel, the connection work of the panel is convenient because it is not necessary to insert and assemble the cerakul between the panels when assembling the panel as in the prior art. And workability is excellent.
