Description
본 고안은 방화셔터의 비상문용 차연스토퍼에 관한 것으로서, 더욱 상세하게는 화재 발생시 방화셔터와 비상문 사이의 틈새로 화염 및 연기가 새어 나가는 것을 기밀하게 차단할 수 있는 방화셔터의 비상문용 차연스토퍼에 관한 것이다.The present invention relates to an emergency door smoke stopper of a fire door, and more particularly, to an emergency door smoke stopper of a fire door shutter capable of confidentially blocking the leakage of flames and smoke into the gap between the fire door and the emergency door when a fire occurs. will be.
일반적으로 방화셔터는 건축물 내부의 통로에 설치되는 것으로, 평상시에는 특정 공간 내부로 외부인이 진입하는 것을 차단하는 역할을 하는 반면, 화재가 발생되는 경우에는 화염, 연기, 유독가스 등이 확산되는 것을 방지하는 역할을 하게 된다. 따라서 일정 규모 이상의 건물(백화점, 쇼핑몰, 대회의장 등)에는 소방법에 의해 그 설치가 의무화되어 있다.In general, a fire shutter is installed in a passageway inside a building, and normally serves to block outsiders from entering a specific space. In the event of a fire, flames, smoke, and toxic gases are prevented from spreading. It will play a role. Therefore, it is mandatory to install the building more than a certain size (department store, shopping mall, conference chair, etc.) by fire method.
이러한 방화셔터는 성능과 안전성의 평가 및 인적 또는 물적 피해를 최소화할 수 있도록 화재 상황을 가정한 내화시험과 차연시험을 통해 내화성, 내충격성, 차연성 등의 여러 요건을 충족시켜야만 한다.These fire shutters must meet various requirements such as fire resistance, impact resistance, and flame retardancy through fire and smoke test assuming a fire situation in order to evaluate performance and safety and minimize human or material damage.
도 1 및 도 2는 이와 같은 방화셔터의 일예를 도시한 것으로서, 방화셔터(S)에는 화재 등의 비상사태 발생시 사람들의 신속한 대피를 위해 비상문(D)이 설치되어 있다.1 and 2 illustrate an example of such a fire prevention shutter, the fire door (S) is provided with an emergency door (D) for the rapid evacuation of people in the event of an emergency such as a fire.
또한, 비상문(D)에는 비상문(D)의 상단부와 방화셔터(S) 사이의 틈새를 차단하기 위해 차연스토퍼(10)가 설치되는데, 이는 방화셔터(S)의 슬랫(S1) 단부를 보강하면서 특히 유독가스나 연기가 누출되는 것을 방지하는 역할을 수행한다.In addition, the emergency door (D) is provided with a smoke stopper (10) to block the gap between the upper end of the emergency door (D) and the fire shutter (S), which is the end of the slat (S1) of the fire shutter (S) While reinforcing, it also plays a role in preventing the leakage of toxic gases and smoke.
그러나 상기와 같은 종래의 방화셔터(S)에 설치된 비상문용 차연스토퍼(10)는 대부분 비상문(D)의 슬랫(D1) 단부에 얇은 철판을 스폿용접 등으로 덧댄 단순한 구조이므로 화재 발생시 고열에 의해 쉽게 열 변형되면서 방화셔터(S)의 내열성과 차연성이 현저하게 떨어지고, 비상문(D)의 정상적인 개폐도 어렵게 되는 등 치명적인 결함이 발생되었다. However, the conventional emergency door smoke stopper 10 installed in the above-described fire prevention shutter (S) is a simple structure in which a thin iron plate is applied to the slat (D1) end of the emergency door (D) by spot welding, etc. Heat-deterioration and flame retardancy of the fire shutter (S) is easily degraded easily, and a fatal defect such as normal opening and closing of the emergency door D is difficult.
또한, 비상문(D)의 슬랫(D1)은 밴딩부(D2)를 통해 서로 결합되는데, 이러한 밴딩부(D2)에는 원활한 결합을 위해 비교적 큰 공차를 설정하게 되고, 이로 인해 비상문(D)이 자중에 의해 처지거나 외력에 의해 휨 변형되는 현상이 발생된다. 이때 차연스토퍼(10)가 방화셔터(S)와 상호 간에 기밀하게 설치되어 있지 않으므로 쉽게 틈새가 발생되고, 이를 통해 연기가 누출되어 제품의 신뢰성이 저하되는 문제점이 있었다.In addition, the slats (D1) of the emergency door (D) is coupled to each other through the bending portion (D2), this bending portion (D2) to set a relatively large tolerance for a smooth coupling, thereby causing the emergency door (D) This phenomenon causes sagging due to its own weight or bending deformation due to external force. At this time, since the smoke stopper 10 is not installed in a gas tight manner with the fire shutter (S), a gap is easily generated, and there is a problem in that smoke is leaked and reliability of the product is lowered.
이에 본 고안은 상기와 같은 제반 문제점을 감안하여 안출된 것으로서, 본 고안의 목적은 화재 발생시 방화셔터의 슬랫과 비상문의 슬랫 사이의 틈새가 더욱더 기밀하게 차폐되어 연기의 누출을 방지할 수 있도록 하는 방화셔터의 비상문용 차연스토퍼를 제공하는 데 있는 것이다.Therefore, the present invention was devised in view of the above-mentioned problems, and an object of the present invention is to ensure that the gap between the slats of the fire prevention shutter and the emergency door slats is more airtightly shielded in case of a fire to prevent the leakage of smoke. It is to provide a smoke stopper for the emergency door of the shutter.
상기한 목적을 달성하기 위해 본 고안은 방화셔터의 슬랫과 비상문의 슬랫 사이에 설치되는 방화셔터의 비상문용 차연스토퍼에 있어서, 상기 차연스토퍼에는 상기 방화셔터와 비상문 사이의 틈새를 기밀하게 차단할 수 있도록 상기 방화셔터의 밴딩부를 감싸면서 결합되는 차폐캡을 형성한 것을 특징으로 한다.In order to achieve the above object, the present invention provides a smoke prevention stopper for an emergency door of a fire prevention shutter installed between a slat of a fire shutter and an emergency door, and the gap between the fire protection shutter and the emergency door can be closed in the smoke stopper. It characterized in that the shielding cap is formed to be coupled while wrapping the bending portion of the fire prevention shutter.
또한, 본 고안에 따라 상기 차폐캡은 그 단면의 형상을 다각 형상으로 형성한 것을 특징으로 한다.In addition, according to the present invention the shielding cap is characterized in that the cross-sectional shape formed in a polygonal shape.
또한, 본 고안에 따라 상기 차폐캡은 그 단면의 형상을 라운드 형상으로 형성한 것을 특징으로 한다.In addition, according to the present invention the shielding cap is characterized in that the cross-sectional shape of the cross-section.

이하, 본 고안에 따른 바람직한 실시 예를 첨부된 도면에 의거하여 보다 구체적으로 설명한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.
여기서, 하기의 모든 도면에서 동일한 기능을 갖는 구성요소는 동일한 참조부호를 사용하여 반복적인 설명은 생략한다. 아울러 후술하는 용어들은 본 고안에서의 기능을 고려하여 정의된 것으로서, 이것은 고유의 통용되는 의미로 해석되어야 함을 명시한다.Here, in all the drawings below, the components having the same function are denoted by the same reference numerals, and repeated description thereof will be omitted. In addition, the terms described below are defined in consideration of the functions in the present invention, which specifies that they should be interpreted in their own commonly used meanings.
도 3은 본 고안에 따른 방화셔터의 비상문용 차연스토퍼의 설치 상태를 도시한 요부사시도이고, 도 4는 도 3의 B-B'선 단면도이다.3 is a main portion perspective view showing a state of installation of the smoke prevention stopper for the emergency door of the fire prevention shutter according to the present invention, Figure 4 is a cross-sectional view taken along line BB 'of FIG.
도 3 및 도 4에 도시된 바와 같이, 본 고안에 따른 비상문용 차연스토퍼(100)의 상부에는 방화셔터(S)의 슬랫(S1)에 형성된 밴딩부(S2)를 감싸게 되는 차폐캡(110)이 형성되어 있다. As shown in Figure 3 and 4, the shielding cap 110 to wrap the banding portion (S2) formed on the slat (S1) of the fire door shutter (S) on the upper portion of the emergency door smoking stopper (100) according to the present invention Is formed.
이때 상기 차폐캡(110)은 금속판재를 열에 의해 쉽게 변형을 일으키지 않으면서 강도를 보강할 수 있도록 절곡하여 다수의 슬랫(S1)을 상호 연결하기 위해 형성된 방화셔터(S)의 밴딩부(S2)를 용이하게 커버함과 동시에 상하면과 측면에 긴밀하게 면접촉되도록 형성한다.At this time, the shielding cap 110 is bent to reinforce the strength of the metal sheet without causing deformation by heat to bend the bending portion (S2) of the fire shutter (S) formed to interconnect the plurality of slats (S1) The cover is easily formed and at the same time formed in close contact with the upper and lower surfaces and the side.
그리고 차연스토퍼(100)의 하부는 비상문(D)의 슬랫(D1) 단부에 견고하게 고정되어 있다.And the lower part of the smoke-stopper 100 is firmly fixed to the end of the slat (D1) of the emergency door (D).
여기서, 차연스토퍼(100)와 비상문(D)의 슬랫(D1)은 방화셔터(S)의 감김 동작에 간섭을 일으키지 않도록 하여 스폿용접 또는 리벳팅 등의 방법으로 결합한다.Here, the smoke stopper 100 and the slats D1 of the emergency door D are coupled by a method such as spot welding or riveting so as not to interfere with the winding operation of the fire prevention shutter S.
따라서 상기 차폐캡(110)은 방화셔터(S)의 밴딩부(S2) 외주면을 감싸듯이 커버하면서 면접촉 및 선접촉되므로 공기의 흐름을 차단하게 되고, 이로 인해 그 기밀성을 극대화시키면서 비상문(D)의 닫힘 상태를 유지시키게 된다.Therefore, the shielding cap 110 covers the outer circumferential surface of the bending part S2 of the fire shutter (S) while covering the surface contact and line contact, thereby blocking the flow of air, thereby maximizing the airtightness and thereby emergency door (D). ) Will remain closed.
또한, 차폐캡(110)을 별도의 복잡한 구성없이 방화셔터(S)의 밴딩부(S2)에 약한 억지 끼움식으로 결합하는 것이므로 차폐구조가 견고하면서 간단한 것이며, 비상문(D)을 열고 닫는데 전혀 지장을 초래하지 않게 된다.In addition, since the shielding cap 110 is coupled to the banding portion (S2) of the fire shutter (S) by a weak interference fit without any complicated configuration, the shielding structure is solid and simple, and open and close the emergency door (D) It will not cause any trouble at all.
다시 말해서, 본 고안은 비상문(D)의 상단부와 방화셔터(S) 사이의 틈새를 완벽하게 차단하기 때문에 차연성을 획기적으로 향상시켜 유독가스 및 연기가 누출되는 것을 방지할 수 있다.In other words, the present invention completely blocks the gap between the upper end of the emergency door (D) and the fire shutter (S) to significantly improve the flammability and prevent the leakage of toxic gas and smoke.
뿐만 아니라, 본 고안은 방화셔터(S)의 밴딩부(S2)에 차폐캡(110)이 걸림된 상태로 유지되므로 비상문(D)의 슬랫(D1)이 자중에 의해 처지거나 외력에 의해 휨 변형되는 것을 방지하게 되고, 이로써 비상문(D)의 개폐가 원활하게 이루어지도록 한다.In addition, the present invention is maintained because the shielding cap 110 is held in the bending portion (S2) of the fire shutter (S), the slat (D1) of the emergency door (D) is sag by its own weight or bent by external force It prevents the deformation, thereby smoothly opening and closing the emergency door (D).
도 5는 본 고안의 다른 실시예를 도시한 것으로서, 상기 차폐캡(110a)의 단면형상을 사각 형상으로 밴딩한 것이다. 이는 도 3 및 도 4를 참조하여 설명한 제 1실시예와 동일 유사한 작용 효과를 가지므로 그 상세한 설명은 생략한다.FIG. 5 illustrates another embodiment of the present invention, in which a cross-sectional shape of the shielding cap 110a is bent into a square shape. This has the same effect as that of the first embodiment described with reference to FIGS. 3 and 4, and thus a detailed description thereof will be omitted.
도 6는 본 고안의 또 다른 실시예를 도시한 것으로서, 상기 차폐캡(110b)의 단면형상을 반원 형상으로 밴딩한 것이다. 이는 방화셔터(S)의 밴딩부(S2)와 차연스토퍼(100)의 차폐캡(110b) 전체가 면접촉되므로 더욱더 기밀해지며, 이로 인하여 연기의 누출을 보다 효과적으로 방지할 수 있게 된다.FIG. 6 illustrates another embodiment of the present invention, in which a cross-sectional shape of the shielding cap 110b is bent in a semicircular shape. It is more airtight because the banding portion (S2) of the fire prevention shutter (S) and the entire shielding cap (110b) of the smoke-stopper 100 is in surface contact, thereby preventing the leakage of smoke more effectively.
도 7은 본 고안의 또 다른 실시예를 도시한 것으로서, 상기 차폐캡(110)을 갖는 차연스토퍼(100a)가 비상문(D)의 상단부 슬랫(D1)과 일체로 형성된 것이다. 이는 비상문(D)의 최상단부 슬랫(D1)을 절곡하여 차폐캡(110)을 형성하므로 차연스토퍼(100a)와 비상문(D)과의 고정작업이 불필요하게 되고, 외력이 가해질 때에도 차연스토퍼(100a)와 비상문(D)의 슬랫(D1)이 서로 이탈되지 않고 더욱 견고한 결합상태를 유지시킬 수 있게 된다.Figure 7 shows another embodiment of the present invention, the shielding stopper (100a) having the shielding cap 110 is formed integrally with the upper end slat (D1) of the emergency door (D). Since the upper end slat (D1) of the emergency door (D) is bent to form the shielding cap (110), it is unnecessary to fix the difference between the smoke stopper (100a) and the emergency door (D), even when an external force is applied. 100a and the slat D1 of the emergency door D can be maintained more firmly coupled without being separated from each other.
한편, 본 고안은 전술한 실시 예 및 첨부된 도면에 의해 한정되는 것이 아니고, 본 고안의 기술적 사상을 벗어나지 않는 범위 내에서 치환, 변형 및 균등한 타 실시 예로 변경할 수 있음은 본 고안이 속하는 기술분야에서 통상의 지식을 가진 자에게 있어서 명백할 것이다.On the other hand, the present invention is not limited to the above-described embodiment and the accompanying drawings, it can be changed to other embodiments equivalent to substitution, modification and equivalent within the scope without departing from the technical spirit of the present invention It will be apparent to those of ordinary skill in Esau.
이상에서와 같이 구성된 본 고안은 방화셔터의 슬랫과 비상문의 슬랫 사이에 발생하는 틈새를 차연스토퍼의 차폐캡이 방화셔터 슬랫의 밴딩부를 따라 감싸듯이 커버하면서 차폐할 수 있기 때문에 화재 발생시에도 공기의 흐름을 차단하여 기밀성을 극대화하고, 이를 통해 방화셔터의 차염 및 차연성을 크게 향상시키는 효과가 있다.The present invention configured as described above can cover the gap generated between the slats of the fire shutter and the emergency door slats while covering the shielding cap of the smoke stopper as if wrapping the banding portion of the fire shutter shutter slat, so that the air flows even in the event of a fire. Maximize airtightness by blocking the through, it has the effect of greatly improving the flame retardant and flame retardant of the fire shutter.
