Description

화재확산 방지기능을 구비하는 내벽용 단열패널 {Insulation panel for inner wall with a function of fire spread prevention}Insulation panel for inner wall with a function of fire spread prevention}

본 발명은 내벽용 단열패널에 관한 것으로, 더 상세하게는 화재 시 두 단열패널의 연결부위를 통해 화염이나 연기가 새어나가지 아니하도록 구성되는 화재확산 방지기능을 구비하는 내벽용 단열패널에 관한 것이다.The present invention relates to an insulating panel for an inner wall, and more particularly, to an insulating panel for an inner wall having a fire spread prevention function configured to prevent flame or smoke from leaking through the connection portion of the two insulating panels during a fire.

건축용 복합자재인 단열패널(일명 '샌드위치패널')은 건물이나 구조물의 벽체 등에 사용되는 건축자재로서, 한 쌍의 금속판재 사이에 스티로폼이나 글라스울 등의 단열재를 개재시키고, 금속판재와 단열재를 접착제로 접착시켜 제조된다. 이러한 단열패널은 시공성, 경제성 등의 장점으로 공장 및 창고건축물에 주로 사용되고 있다.Insulation panels (also known as'sandwich panels'), which are composite materials for construction, are building materials used for the walls of buildings or structures. Insulation materials such as styrofoam or glass wool are interposed between a pair of metal plates, and the metal plate and insulation are glued together. It is prepared by bonding with. These insulation panels are mainly used in factories and warehouse buildings due to the advantages of constructability and economy.

그러나 단열패널은 단열재의 가연성으로 인해 화재 위험성이 높아 인명 및 재산피해가 계속되고 있는 실정이다. 특히 단열패널은 여러 개를 연결하여 조립하여 시공하는 방식으로 시공되므로, 약 1미터 간격으로 패널과 패널의 이음부위(조인트)부위가 발생되며, 화재 시 조인트 부위를 통해 화염이 급격히 확산되는 현상이 발생한다. 이와 같이 패널과 패널의 연결부를 통한 화재의 확산은 재실자의 피난 및 소방대원의 화재진압에 큰 위험을 초래하며, 지속적인 공장 화재로 인명 및 재산피해를 발생시키게 된다.However, due to the flammability of the insulation panel, the risk of fire is high, and human and property damage continues. In particular, since the insulation panels are constructed by assembling and connecting several, the joints (joints) between the panels and panels are generated at about 1 meter intervals, and flames spread rapidly through the joints in case of fire. Occurs. As such, the spread of fire through the connection between the panel and the panel poses a great risk to evacuation of occupants and fire extinguishing by firefighters, and damages to life and property are caused by continuous factory fire.

이와 같은 문제점을 해결하기 위하여, 두 개의 단열패널 사이를 기밀시키는 확산방지 구조체가 제안된 바 있다.In order to solve such a problem, a diffusion preventing structure for sealing between two insulating panels has been proposed.

이하 첨부된 도면을 참조하여 종래의 확산방지 구조체에 대하여 상세히 설명한다.Hereinafter, a conventional diffusion preventing structure will be described in detail with reference to the accompanying drawings.

도 1 및 도 2는 종래의 확산방지 구조체가 두 개의 단열패널 사이에 장착되는 구조를 도시하는 단면도이다.1 and 2 are cross-sectional views showing a structure in which a conventional diffusion preventing structure is mounted between two insulating panels.

일반적으로 단열패널(1)은 한 쌍의 금속판재(1a) 사이에 스티로폼이나 글라스울 등의 단열재(1b)가 개재된 구조로 구성되며, 양측부에 다른 단열패널(1)과의 연결을 위한 조인트가 배치된다. 여기서 상기 단열패널(1)의 상호 연결을 위한 조인트는 단열패널(1)의 일측에 형성되는 커플링부(2)와, 단열패널(1)의 다른 일측에 오목하게 형성되어 다른 단열패널(1)의 커플링부(2)가 삽입되면서 연결되는 커플링홈(3)으로 구성된다.In general, the insulation panel (1) is composed of a structure in which an insulation material (1b) such as styrofoam or glass wool is interposed between a pair of metal plates (1a), and for connection with other insulation panels (1) on both sides. The joint is placed. Here, the joint for mutual connection of the insulation panel 1 is a coupling part 2 formed on one side of the insulation panel 1, and the other insulation panel 1 is formed concave on the other side of the insulation panel 1 It consists of a coupling groove (3) connected while the coupling portion (2) is inserted.

종래의 화재 확산 방지 구조체(10)는 어느 한 단열패널(1)의 커플링홈(3)과, 상기 커플링홈(3) 내측으로 삽입되는 다른 한 단열패널(1)의 커플링부(2)의 사이에 개재되게 설치되어, 화재시 열에 의해 발포하여 단열패널(1)의 조인트를 통해서 화염이 확산되는 것을 방지하는 기능을 한다.The conventional fire spread prevention structure 10 is between the coupling groove 3 of one insulating panel 1 and the coupling portion 2 of the other insulating panel 1 inserted into the coupling groove 3 It is installed to be interposed in the fire, and functions to prevent the flame from spreading through the joint of the insulation panel (1) by foaming by heat.

화재 확산 방지 구조체(10)는, 상기 커플링부(2)의 외면과 상기 커플링부(2)가 삽입되는 커플링홈(3)의 외면 사이에 배치되는 단단한 재질로 된 강체플레이트(11)와, 상기 강체플레이트(11)가 부분적으로 또는 전체적으로 은폐되도록 강체플레이트(11)를 둘러싸도록 설치되는 열팽창성 수지 재질의 발포커버(12)를 포함한다. 상기 발포커버(12)의 양측에 구비된 확장차폐부(13)는 커플링부(2)와 커플링홈(3)의 양측면 사이에 개재되며, 한쌍의 금속판재(1a)와 함께 리벳결합되게 된다. 이에 따라, 화재시 발생하는 열에 의해 발포되어 팽창하면 커플링부(2)와 커플링홈(3) 사이의 틈새를 고밀도 채우게 된다. 따라서 상호 결합된 커플링부(2)와 커플링홈(3) 사이로는 화염이 통과하지 못하게 된다.The fire spread prevention structure 10 includes a rigid plate 11 made of a rigid material disposed between the outer surface of the coupling part 2 and the outer surface of the coupling groove 3 into which the coupling part 2 is inserted, and the It includes a foam cover 12 made of a thermally expandable resin material that is installed to surround the rigid plate 11 so that the rigid plate 11 is partially or completely concealed. Expansion shielding portions 13 provided on both sides of the foam cover 12 are interposed between the coupling portion 2 and both sides of the coupling groove 3, and are riveted together with a pair of metal plates 1a. Accordingly, when foamed and expanded by heat generated during a fire, the gap between the coupling portion 2 and the coupling groove 3 is filled with high density. Therefore, the flame does not pass between the coupling portion 2 and the coupling groove 3 coupled to each other.

상기 언급한 바와 같이 종래의 확산 방지 구조체(10)를 이용하면 두 단열패널(1) 사이의 연결부위를 통해 화재가 확산되는 현상을 방지할 수 있지만, 확산 방지 구조체(10)를 제작하는데 많은 비용이 소모될 뿐만 아니라, 확장차폐부(13)가 커플링부(2)와 커플링홈(3) 사이에 끼워지도록 두 단열패널(1)을 조립하는데 많은 리벳팅 작업이 필요하게 되어, 많은 시공시간이 소요되고, 시공비용이 증가하는 등의 어려움이 있어 시공성이 떨어진다는 문제점이 있다. 또한 확장차폐부(13)의 조립을 위해 리벳결합이 사용되므로 리벳(15)이 외부로 노출되어 미관상 좋지 않아 심미감이 없다는 문제점이 있다.As mentioned above, the use of the conventional diffusion prevention structure 10 can prevent the spread of fire through the connection between the two insulation panels 1, but it is expensive to manufacture the diffusion prevention structure 10. In addition to this consumption, a lot of riveting work is required to assemble the two insulating panels 1 so that the expansion shielding part 13 is fitted between the coupling part 2 and the coupling groove 3, and a lot of construction time is required. It is required, and there is a problem in that the constructability is deteriorated due to difficulties such as an increase in construction cost. In addition, since rivet coupling is used for assembling the expansion shield 13, the rivet 15 is exposed to the outside and is not aesthetically pleasing, so there is a problem that there is no aesthetic feeling.

본 발명에 의한 내벽용 단열패널은 건축구조물의 내벽을 이루도록 다수 개가 조립되는 조립식 건축자재의 일종으로서, 일정 수준 이상의 강도와 단열성을 가지면서 화재 발생 시 이웃하는 두 개의 단열패널 연결부위로 화염이나 연기가 새어나오지 아니하도록 구성된다는 점에 가장 큰 특징이 있다.Insulation panel for inner wall according to the present invention is a kind of prefabricated building material in which a number of pieces are assembled to form the inner wall of a building structure, and has a certain level of strength and thermal insulation, and flames or smoke are connected to two adjacent insulating panels when a fire occurs. The biggest feature is that it is constructed so that it does not leak out.

즉, 본 발명에 의한 내벽용 단열패널은, 평행하게 배열되되 폭방향 일측과 타측에 각각 하나 이상의 삽입홈(130)이 형성되도록 폭방향 양측이 절곡되는 한 쌍의 금속판재(100)와, 상기 한 쌍의 금속판재(100) 사이를 채우는 단열재(200)와, 서로 다른 두 쌍의 금속판재(100)가 폭방향으로 연결될 때 일측 금속판재(100)의 삽입홈(130)에 일단이 삽입되고 타측 금속판재(100)의 삽입홈(130)에 타단이 삽입되는 방화석고보드(300)를 포함하여 구성된다.That is, the heat insulating panel for an inner wall according to the present invention is a pair of metal plates 100 which are arranged in parallel but bent at both sides in the width direction so that at least one insertion groove 130 is formed on one side and the other side in the width direction, respectively, and the One end is inserted into the insertion groove 130 of the one side of the metal plate 100 when the insulating material 200 filling between the pair of metal plate 100 and the two different pairs of metal plate 100 are connected in the width direction It is configured to include a fireproof gypsum board 300 into which the other end is inserted into the insertion groove 130 of the other metal plate 100.

상기 한 쌍의 금속판재(100)는 내벽을 이루도록 시공되었을 때 구조적 강성을 갖도록 하기 위한 구성으로, 아연도금강판을 포함하여 다양한 금속판재가 사용될 수 있고, 상기 단열재(200)는 내벽을 이루도록 시공되었을 때 단열성을 갖도록 하기 위한 것으로서 글라스울이나 미네랄울, 스티로폼 등 내부에 다수의 공기층을 가지거나 단열성능을 가진다면 어떠한 재료로도 이루어질 수 있다. The pair of metal plates 100 are configured to have structural rigidity when constructed to form an inner wall, and various metal plates including galvanized steel may be used, and the heat insulating material 200 is constructed to form an inner wall. It is intended to have thermal insulation, and may be made of any material if it has a plurality of air layers inside, such as glass wool, mineral wool, or styrofoam, or has thermal insulation performance.

이때 두 개의 내벽용 단열패널이 단순히 끼워맞춤 구조로 연결되면, 화재가 발생하여 상기 금속판재(100)가 열팽창하는 경우 연결부위가 벌어지는바, 벌어진 연결부위를 통해 화염이 통과하여 화재가 크게 확산되며, 벌어진 연결부위를 통해 연기가 새어 나감으로써 인명피해가 증가하게 된다는 문제가 발생된다.At this time, when the two inner wall insulation panels are simply connected in a fitting structure, when a fire occurs and the metal plate 100 expands thermally, the connection part is opened, and the flame passes through the open connection part, and the fire spreads greatly. However, there is a problem that the damage to people increases as smoke leaks out through the open joint.

본 발명에 의한 내벽용 단열패널은 이와 같은 문제점 즉, 단열패널의 연결부위를 통해 화염이나 연기가 새어나가는 현상을 방지할 수 있도록, 상기 단열패널의 연결부위에 방화석고보드(300)와 보강브라켓(400)이 삽입된다는 점에 구성상의 가장 큰 특징이 있다.Insulation panel for inner wall according to the present invention has a fireproof gypsum board 300 and a reinforcing bracket at the connection part of the insulation panel so as to prevent such problems, that is, flame or smoke leaking through the connection part of the insulation panel. The biggest feature of the construction is that (400) is inserted.

상기 방화석고보드(300)는 화재가 발생하더라도 연소되지 아니하는 물질로 제작되며, 고온의 열이 인가되더라도 변형이 크게 발생하지 아니한다는 특성이 있다. 따라서 도 4에 도시된 바와 같이 두 개의 단열패널이 연이어 연결되었을 때 연결된 부위에 방화석고보드(300)가 삽입되면, 화재가 발생하더라도 두 개의 단열패널 연결부위가 열팽창되어 벌어지는 현상이 발생하지 아니하는바, 화염이 유출되어 화재가 확산되는 현상과 연기가 유출되는 현상을 방지할 수 있다는 장점이 있다.The fireproof gypsum board 300 is made of a material that does not burn even when a fire occurs, and has a characteristic that deformation does not occur significantly even when high temperature heat is applied. Therefore, as shown in FIG. 4, when the fireproof gypsum board 300 is inserted into the connected part when the two insulation panels are connected in succession, even if a fire occurs, the phenomenon of thermal expansion of the two insulation panel connection parts does not occur. Bar, there is an advantage in that it is possible to prevent the phenomenon that the fire spreads and smoke leaks due to the outflow of the flame.

이때, 상기 방화석고보드(300)는 금속판재(100)에 비해 강도가 낮으므로, 외력이 인가되었을 때 파단될 우려가 있다. 이와 같이 상기 방화석고보드(300)가 파단되면 두 개의 단열패널 사이를 차단하는 역할을 하지 못하므로, 화염 및 연기가 두 개의 단열패널 사이를 통과하게 되는 결과가 초래된다.At this time, since the fireproof gypsum board 300 has a lower strength than the metal plate 100, there is a risk of fracture when an external force is applied. In this way, when the fireproof gypsum board 300 is broken, it does not play a role of blocking between the two insulation panels, resulting in flames and smoke passing between the two insulation panels.

본 발명에 의한 내벽용 단열패널은 이와 같은 문제점을 해결할 수 있도록, 와, 상기 방화석고보드(300)의 외측면 일부를 덮도록 장착되는 보강브라켓(400)을 구비한다는 점에 구성상의 또 다른 특징이 있다. 상기 보강브라켓(400)은 기준치 이상의 굽힘강도 및 인장강도를 가질 수 있도록 강판으로 제작되되, 상기 방화석고보드(300)에 일체로 부착되도록 결합된다. 이때 상기 보강브라켓(400)은 방화석고보드(300)와 일체로 밀착 결합될 수 있도록 별도의 접착제에 의해 결합될 수 있다.Insulation panel for inner wall according to the present invention is another feature of the configuration in that it has a reinforcing bracket 400 mounted to cover a part of the outer surface of the fireproof gypsum board 300 so as to solve such a problem. There is this. The reinforcing bracket 400 is made of a steel plate so as to have a bending strength and a tensile strength greater than or equal to a reference value, and is coupled to be integrally attached to the fireproof gypsum board 300. At this time, the reinforcing bracket 400 may be coupled by a separate adhesive so that it can be integrally coupled with the fireproof gypsum board 300.

이와 같이 방화석고보드(300)에 보강브라켓(400)이 결합되면, 외력이 인가될 때 상기 보강브라켓(400)이 방화석고보드(300)의 파단을 방지하는 역할을 수행하는바, 상기 보강브라켓(400)이 파단되지 아니하는 한 방화석고보드(300) 역시 파단되지 아니하게 된다. 따라서 연이어 결합되는 두 단열패널의 연결부위는 상기 방화석고보드(300)에 의해 안정적으로 차단되므로, 화염이나 연기가 두 단열패널의 연결부위를 통해 유출되는 현상을 방지할 수 있게 된다.In this way, when the reinforcing bracket 400 is coupled to the fireproof gypsum board 300, the reinforcing bracket 400 serves to prevent the fireproof gypsum board 300 from breaking when an external force is applied. As long as 400 is not broken, the fireproof gypsum board 300 is also not broken. Therefore, since the connection part of the two insulation panels that are connected in succession is stably blocked by the fireproof gypsum board 300, it is possible to prevent a phenomenon in which flame or smoke is leaked through the connection part of the two insulation panels.

또한, 상기 보강브라켓(400)이 방화석고보드(300)의 일면을 덮는 하나의 평판 형상으로 형성되면, 상기 보강브라켓(400)이 방화석고보드(300)로부터 쉽게 분리될 수 있을 뿐만 아니라, 상기 방화석고보드(300)의 폭방향(도 4에서는 좌우방향)으로 인가되는 외력에 의해 상기 방화석고보드(300)가 파손되는 현상을 방지하지 못한다는 문제가 발생된다.In addition, when the reinforcing bracket 400 is formed in a single plate shape covering one surface of the fireproof gypsum board 300, the reinforcing bracket 400 can be easily separated from the fireproof gypsum board 300, and the There arises a problem that the fireproof gypsum board 300 cannot be prevented from being damaged by an external force applied in the width direction of the fireproof gypsum board 300 (left and right directions in FIG. 4).

따라서 상기 보강브라켓(400)은 도 5에 도시된 바와 같이, 상기 방화석고보드(300)의 일면(본 실시예에서는 상면)을 덮는 몸체판(410)과, 상기 방화석고보드(300)의 폭방향 양단(본 실시예에서는 좌우측단)을 덮는 측판(420)으로 구성됨이 바람직하다. 이와 같이 상기 보강브라켓(400)이 방화석고보드(300)의 일면과 폭방향 양단을 덮도록 구성되면, 상기 방화석고보드(300)의 두께방향으로 인가되는 외력에 의해 상기 방화석고보드(300)가 파손되는 현상을 방지할 수 있을 뿐만 아니라, 상기 방화석고보드(300)의 폭방향으로 인가되는 외력에 의해 상기 방화석고보드(300)가 파손되는 현상을 방지할 수도 있다는 장점이 있다.Accordingly, the reinforcing bracket 400 has a body plate 410 covering one surface (in this embodiment, the upper surface) of the fireproof gypsum board 300, and the width of the fireproof gypsum board 300, as shown in FIG. It is preferable that it is composed of side plates 420 covering both ends in the direction (left and right ends in this embodiment). In this way, when the reinforcing bracket 400 is configured to cover one surface of the fireproof gypsum board 300 and both ends in the width direction, the fireproof gypsum board 300 by an external force applied in the thickness direction of the fireproof gypsum board 300 There is an advantage in that it is possible not only to prevent the phenomenon of being damaged, but also to prevent the phenomenon that the fireproof gypsum board 300 is damaged by an external force applied in the width direction of the fireproof gypsum board 300.

한편, 두 개의 단열패널이 폭방향으로 연이어 결합될 때에는 폭방향으로 이웃하는 두 개의 금속판재(100)가 완벽하게 밀착되지 못한다는 문제점 즉, 폭방향으로 이웃하는 두 개의 금속판재(100) 사이에 틈새가 발생된다는 문제점이 있다.On the other hand, when two insulation panels are connected in a row in the width direction, the problem that the two metal plate members 100 adjacent in the width direction cannot be perfectly adhered, that is, between the two metal plate members 100 adjacent in the width direction. There is a problem that a gap is generated.

상기 보강브라켓(400)은 폭방향으로 이웃하는 두 개의 금속판재(100) 사이의 틈새를 완벽하게 메울 수 있도록, 상기 몸체판(410)의 중단에 돌출절곡부(412)가 형성된다. 상기 돌출절곡부(412)는 폭방향으로 연결되는 두 개의 금속판재(100) 사이에 끼워지도록 외측(본 실시예에서는 상하측)을 향해 돌출되는 방향으로 'ㄷ'자 형상으로 절곡된다.The reinforcing bracket 400 has a protruding bent portion 412 formed at the middle of the body plate 410 so as to completely fill the gap between the two adjacent metal plates 100 in the width direction. The protruding bent part 412 is bent in a'C' shape in a direction protruding toward the outside (up and down in this embodiment) so as to be fitted between two metal plates 100 connected in the width direction.

이와 같이 보강브라켓(400)의 상판에 돌출절곡부(412)가 형성되면, 두 개의 단열패널이 폭방향으로 연결되었을 때 폭방향으로 이웃하는 두 개의 금속판재(100) 사이에 상기 돌출절곡부(412)가 압입되는바, 폭방향으로 이웃하는 두 금속판재(100) 사이의 틈새가 보다 효과적으로 막혀진다는 장점이 있다. 또한, 상기 돌출절곡부(412)가 본 실시예에 도시된 바와 같이 'ㄷ'자 형상으로 절곡되면, 상기 돌출절곡부(412)의 내부에는 상기 방화석고보드(300)를 향하는 측이 개방된 공간이 확보된다. 따라서 도 4에 도시된 상태에서 상기 금속판재(100)에 좌우방향 충격력이 인가되었을 때 상기 돌출절곡부(412)가 일정 수준 변형되면서 충격력을 흡수하므로, 상기 금속판재(100)의 변형 및 파손을 감소시킬 수 있다는 장점도 있다.In this way, when the protruding bent portion 412 is formed on the upper plate of the reinforcing bracket 400, the protruding bent portion is between two metal plates 100 adjacent in the width direction when the two insulating panels are connected in the width direction. Bar 412 is press-fitted, there is an advantage that the gap between the two metal plates 100 adjacent in the width direction is more effectively blocked. In addition, when the protruding bent part 412 is bent in a'c' shape as shown in this embodiment, the side facing the fireproof gypsum board 300 is opened inside the protruding bent part 412 Space is secured. Therefore, when an impact force in the left and right directions is applied to the metal plate 100 in the state shown in FIG. 4, the protruding bent portion 412 is deformed to a certain level and absorbs the impact force, so that deformation and damage of the metal plate 100 is prevented. There is also an advantage that it can be reduced.

한편, 두 개의 단열패널이 폭방향으로 연이어 연결될 때 연결부위의 강도 및 기밀성이 향상될 수 있도록, 상기 단열패널의 폭방향 양측에는 상호 형합되는 형상의 돌출부(110) 및 인입부(120)가 형성될 수 있다. 즉, 상기 한 쌍의 금속판재(100)는, 각각의 폭방향 일측(도 3에서는 좌측) 끝단이 하나의 돌출부(110)를 형성하도록 절곡되고, 각각의 폭방향 타측(도 3에서는 우측) 끝단이 상기 돌출부(110)가 삽입 가능한 인입부(120)를 형성하도록 절곡된다.On the other hand, so that the strength and airtightness of the connection part can be improved when the two insulation panels are connected in succession in the width direction, protrusions 110 and lead-in parts 120 of mutually mating shapes are formed on both sides of the width direction of the insulation panel. Can be. That is, the pair of metal plate 100 is bent so that one end of each width direction (left in FIG. 3) forms one protrusion 110, and the other end of each width direction (right in FIG. 3) The protrusion 110 is bent to form an insertable inlet 120.

이와 같이 돌출부(110) 및 절곡부가 형성되면, 도 4에 도시된 바와 같이 두 개의 단열패널이 폭방향으로 연결되었을 때 결합부위의 강도가 우수해질뿐만 아니라, 상호 맞닿는 금속판재(100) 간의 접촉면적이 증가하므로 기밀성이 향상된다는 장점이 있다.When the protruding part 110 and the bent part are formed in this way, as shown in FIG. 4, when the two insulation panels are connected in the width direction, the strength of the bonding part is excellent, as well as the contact area between the metal plates 100 in contact with each other. There is an advantage that the airtightness is improved because this increases.

이때, 본 발명에 의한 내벽용 단열패널은 상기 돌출부(110) 및 절곡부가 두 개의 방화석고보드(300) 사이에 위치될 수 있도록, 상기 한 쌍의 금속판재(100)는 폭방향 양측에 삽입홈(130)이 각각 하나씩 형성된다. 이에 따라 단열패널의 양측 각각에는 삽입홈(130)이 두께방향으로 두 개가 형성되게 되는 구조를 가지게 된다. 이 경우 상기 돌출부(110)와 인입부(120)는 상기 단열재(200)의 두께방향으로 대응되는 두 개의 삽입홈(130) 사이에 형성됨이 바람직하다.At this time, the heat insulation panel for the inner wall according to the present invention, so that the protrusion 110 and the bent portion can be positioned between the two fireproof gypsum boards 300, the pair of metal plate 100 is inserted into the groove on both sides in the width direction Each 130 is formed. Accordingly, it has a structure in which two insertion grooves 130 are formed in the thickness direction at each side of the insulating panel. In this case, the protrusion 110 and the inlet 120 are preferably formed between the two insertion grooves 130 corresponding in the thickness direction of the insulating material 200.

도 4에 도시된 바와 같이 돌출부(110) 및 절곡부가 단열재(200)의 두께방향(도 4에서는 상하방향)으로 배열된 두 개의 방화석고보드(300) 사이에 위치하게 되면, 화염이나 연기가 두 개의 단열패널 연결부위를 통과하기가 매우 어려워지므로, 화재확산 및 연기확산을 방지할 수 있다는 장점이 있다.As shown in Fig. 4, when the protrusion 110 and the bent portion are positioned between the two fireproof gypsum boards 300 arranged in the thickness direction of the insulation 200 (up and down in Fig. 4), flames or smoke Since it becomes very difficult to pass through the joints of two insulation panels, there is an advantage in that it is possible to prevent the spread of fire and smoke.

도 6은 방화석고보드(300)와 보강브라켓(400)의 결합구조 제2 실시예를 도시하는 분해사시도이다.6 is an exploded perspective view showing a second embodiment of the coupling structure between the fireproof gypsum board 300 and the reinforcing bracket 400.

방화석고보드(300)에 결합되는 보강브라켓(400)이 도 5에 도시된 형상으로 형성되면, 보강브라켓(400)과 방화석고보드(300) 간의 접착력이 약해졌을 때 상기 보강브라켓(400)이 방화석고보드(300)로부터 쉽게 탈거될 우려가 있다.When the reinforcing bracket 400 coupled to the fireproof gypsum board 300 is formed in the shape shown in FIG. 5, the reinforcing bracket 400 is weakened when the adhesion between the reinforcing bracket 400 and the fireproof gypsum board 300 is weakened. There is a risk of being easily removed from the fireproof gypsum board 300.

본 발명에 의한 내벽용 단열패널은 보강브라켓(400)과 방화석고보드(300)를 접착시키는 접착제의 접착력이 약해지더라도 상기 보강브라켓(400)이 방화석고부드로부터 쉽게 탈거되지 아니하도록, 상기 측판(420)의 끝단에는 상기 방화석고보드(300)의 타면(도 6에서는 저면) 가장자리에 걸쳐지는 걸림단(422)이 형성될 수 있다.Insulation panel for inner wall according to the present invention is the side plate so that the reinforcing bracket 400 is not easily removed from the fire-resistant gypsum board even if the adhesive strength of the adhesive bonding the reinforcing bracket 400 and the fire-proof gypsum board 300 is weakened. At the end of the fireproof gypsum board 300, a locking end 422 may be formed over the edge of the other surface (bottom surface in FIG. 6).

이와 같이 측판(420)의 끝단에 걸림단(422)이 형성되면, 도 6에 도시된 상태에서 상기 보강브라켓(400)에 상향 외력이 인가되더라도 상기 걸림단(422)이 파손되지 아니하는 한 방화석고보드(300)로부터 분리되지 아니하게 된다는 장점이 있다.When the locking end 422 is formed at the end of the side plate 420 in this way, even if an upward external force is applied to the reinforcing bracket 400 in the state shown in FIG. 6, fire protection as long as the locking end 422 is not damaged. There is an advantage that it is not separated from the gypsum board 300.

이때, 상기 걸림단(422)의 길이가 너무 짧으면 걸림단(422)의 기능을 정상적으로 수행할 수 없고, 상기 걸림단(422)의 길이가 너무 길면 보강브라켓(400)을 방화석고보드(300)에 결합시키는 작업이 어려워진다는 문제점이 있다. 따라서 상기 걸림단(422)의 길이는 보강브라켓(400)과 방화석고보드(300)의 재질 및 규격에 따라 적절하게 선택되어야 할 것이다.At this time, if the length of the locking end 422 is too short, the function of the locking end 422 cannot be normally performed, and if the length of the locking end 422 is too long, the reinforcing bracket 400 is attached to the fireproof gypsum board 300 There is a problem that it becomes difficult to bind to. Therefore, the length of the locking end 422 should be appropriately selected according to the material and specifications of the reinforcing bracket 400 and the fireproof gypsum board 300.

도 7은 방화석고보드(300)와 보강브라켓(400)의 결합구조 제3 실시예를 도시하는 분해사시도이다.7 is an exploded perspective view showing a third embodiment of the coupling structure of the fireproof gypsum board 300 and the reinforcing bracket 400.

도 5 및 도 6에 도시된 실시예와 같이 보강브라켓(400)의 측판(420)이 방화석고보드(300)의 폭방향 양단만을 덮고 방화석고보드(300)의 전후방향 양단은 덮지 아니하도록 구성되면, 상기 보강브라켓(400)에 전후방향 외력이 인가되었을 때 보강브라켓(400)이 방화석고보드(300)로부터 분리될 우려가 있다. 물론, 상기 측판(420)을 방화석고보드(300)의 폭방향 양단과 전후방향 양단을 모두 덮도록 형성하면 상기와 같은 문제점을 해결할 수 있으나, 이와 같이 상기 측판(420)이 방화석고보드(300)의 사방 측단을 모두 덮도록 제작하면 보강브라켓(400)을 방화석고보드(300)에 결합시키는 작업에 어려움이 있을 수 있다.5 and 6, the side plate 420 of the reinforcing bracket 400 covers only both ends in the width direction of the fireproof gypsum board 300 and does not cover both ends in the front and rear direction of the fireproof gypsum board 300 If so, there is a concern that the reinforcement bracket 400 may be separated from the fireproof gypsum board 300 when an external force in the front and rear direction is applied to the reinforcement bracket 400. Of course, if the side plate 420 is formed to cover both ends in the width direction and both ends in the front and rear direction of the fireproof gypsum board 300, the above problem can be solved, but the side plate 420 is If it is manufactured so as to cover all the four side ends of ), it may be difficult to couple the reinforcing bracket 400 to the fireproof gypsum board 300.

따라서 본 발명에 의한 내벽용 단열패널은 도 7에 도시된 바와 같이, 상기 방화석고보드(300)의 일면에 끝단이 삽입되는 하나 이상의 고정돌기(414)가 상기 몸체판(410)에 형성될 수 있다. 이와 같이 몸체판(410)의 내측면에 고정돌기(414)가 형성되면, 상기 보강브라켓(400)을 방화석고보드(300)에 결합시켰을 때 고정돌기(414)의 끝단이 방화석고보드(300)를 파고들어가므로, 상기 보강브라켓(400)에 전후방향 외력이 인가되더라도 보강브라켓(400)이 방화석고보드(300)로부터 쉽게 탈거되지 아니하게 된다는 효과를 얻을 수 있다. 이때 상기 고정돌기(414)의 형상 및 개수는 방화석고보드(300)의 재질 등 여러가지 조건에 따라 다양하게 변경될 수 있다.Therefore, as shown in FIG. 7, the insulation panel for an inner wall according to the present invention may have one or more fixing protrusions 414 into which an end is inserted into one surface of the fireproof gypsum board 300 is formed on the body plate 410. have. When the fixing protrusion 414 is formed on the inner surface of the body plate 410 in this way, when the reinforcing bracket 400 is coupled to the fireproof gypsum board 300, the end of the fixing protrusion 414 is the fireproof gypsum board 300 ), it is possible to obtain the effect that the reinforcing bracket 400 is not easily removed from the fireproof gypsum board 300 even if an external force in the front and rear directions is applied to the reinforcing bracket 400. At this time, the shape and number of the fixing protrusions 414 may be variously changed according to various conditions such as the material of the fireproof gypsum board 300.
