Description
본 발명은 차열성능을 구비한 방화셔터에 관한 것이다.The present invention relates to a fire shutter with heat insulation performance.
방화셔터는 방화구획의 용도로 화재 발생 시 연기 및 열을 감지하여 자동 폐쇄하는 장치로서 넓은 공간에 부득이하게 내화주조로 된 벽을 설치하지 못하는 경우에 사용되어 진다.A fire shutter is a device that senses smoke and heat and automatically closes in the event of a fire for the purpose of a fire prevention compartment. It is used when it is unavoidable to install a wall made of fire-resistant casting in a large space.
통상적인 방화셔터는 가이드레일에 의해 양 측 단이 지지를 받고, 전동개폐기에 연결되어 회전 가능한 샤프트에 일 끝단이 결합되고, 다른 일 끝단은 보텀바가 결합되는 스라트 또는 방화스크린으로 이루어진 셔터부가 하나의 방화막을 형성하여 연기 또는 화염을 차단 및 번지는 것을 막아내는 역할을 한다.A typical fire shutter is supported at both ends by a guide rail, has one end connected to a rotatable shaft connected to an electric switch, and has a shutter section made of a slat or fire screen to which a bottom bar is connected at the other end. It forms a fire barrier that blocks smoke or flames and prevents them from spreading.
이러한 방화셔터의 펼쳐진 셔터부에 양 압 또는 음압의 풍압이 작용 될 경우 셔터부가 부풀어 오르거나 오목하게 되어 가이드 레일에 접촉되는 셔터부의 좌우측끝단에 힘이 작용하게 되고, 이로 인하여 셔터부의 좌우측 끝단이 손상을 입어 방화막의 기능이 저하될 수 있다.When positive or negative wind pressure is applied to the unfolded shutter part of such a fire shutter, the shutter part swells or becomes concave and a force is applied to the left and right ends of the shutter part that contact the guide rail, resulting in damage to the left and right ends of the shutter part. This may deteriorate the function of the fire barrier.
또한 방화셔터는 법령에 의해 비차열 1시간 이상, 차연 성능과 개페성능을 갖추도록 하고 있고, 차열성능에 대한 규정은 없는 상황으로, 화염은 차단할 수 있으나 대류열 및 복사열에 의해 방화셔터에 인접한 가연물이 섭씨 450도 이상으로 온도가 상승할 경우 착화되는 문제점, 즉 화재확산 우려가 있다는 점이다.In addition, fire shutters are required by law to have a non-insulating property of at least 1 hour, blocking performance, and opening/opening performance. There are no regulations on heat insulation performance, so they can block flames, but convection heat and radiant heat can cause combustibles adjacent to the fire shutter to be damaged. If the temperature rises above 450 degrees Celsius, there is a risk of ignition, that is, the spread of fire.
이에 방화셔터의 차열성능을 강화시키기 위해서 수막을 형성하거나, 이중 셔터부 구조 (등록특허 10-2064467호 참조) 및 이중셔터 사이에 물을 분사하는 장치를 구비한 방화셔터(등록특허 10-2262150호, 10-1994223호 참조)가 개시되었다.Accordingly, in order to strengthen the heat shielding performance of the fire shutter, a water film is formed, a double shutter structure (see Patent No. 10-2064467), and a fire shutter equipped with a device for spraying water between the double shutters (Patent No. 10-2262150) are used. , see No. 10-1994223) was disclosed.

The purpose is to provide a structure that overcomes the vulnerability of the shutter part to wind pressure by rotating the roller to roll up the shutter part in both directions, or to place the roller in the middle of the shutter part when forming a fire barrier by unfolding the shutter part. Do it as

As an example, this is a side view to explain the configuration of a capillary water channel formed in a shutter part made of fire-retardant coated silica cloth.
본 발명에 따른 차열성능을 구비한 방화셔터는 천정콘크리트면에 결합되어 설치되는 방화구획시설(1)의 하단부에 연결된 상태로 설치되며, 물공급관(2)과; 스라트 또는 방화코팅된 실리카천으로 이루어지며 복수의 모세물길통(31)이 형성됨을 특징으로 한 셔터부(3)와; 양 끝단에는 체인기어, 원주면 일부에는 물길 홈(43)이 형성되며, 원호고정판(44)으로 셔터부의 중간부위에 결합되는 롤러(4)와; 제어반의 제어신호를 받아서 롤러를 회전시키면서 수직으로 승강시키는 롤러구동장치(5)를 구비함을 특징으로 한다.The fire shutter with heat insulation performance according to the present invention is installed connected to the lower part of the fire partition facility (1) installed by being coupled to the ceiling concrete surface, and includes a water supply pipe (2); A shutter portion (3) made of slat or fire-retardant coated silica cloth and having a plurality of capillary channels (31); A roller (4) having chain gears at both ends, a water channel groove (43) formed on a portion of the circumferential surface, and coupled to the middle of the shutter portion with an arc fixing plate (44); It is characterized by a roller drive device (5) that receives a control signal from the control panel and rotates the roller to vertically raise and lower it.
천정콘크리트 면으로부터 천정 마감재(12)까지의 사이에 형성된 공간에 방화셔터를 설치할 경우, 방화셔터부터 천정콘크리트 면까지의 공간에 대하여, 배관에 대한 손상 없이 방화구획에 준하는 시설을 각 파이프와 금속판재를 이용하여 설치하여야 한다.When installing a fire shutter in the space formed between the ceiling concrete surface and the ceiling finishing material (12), a facility equivalent to a fire prevention partition must be installed in the space from the fire shutter to the ceiling concrete surface without damaging the pipes by installing each pipe and metal plate. It must be installed using .
상기 물공급관(2)은 천정콘크리트면에 설치되는 방화구획시설의 하단부에 결합된 프레임(11)에 설치되며, 스프링클러 급수관 또는 자체 물탱크에 연결되며 방화셔터 인근 열감지센서의 신호를 처리한 제어반의 신호를 받아 작동되는 전자밸브(21)와; 각각의 모세물길통에 삽입된 노즐(22)을 구비함을 특징으로 한다.The water supply pipe (2) is installed in the frame (11) connected to the lower part of the fire partition facility installed on the ceiling concrete surface, is connected to the sprinkler water supply pipe or its own water tank, and is a control panel that processes the signal from a heat sensor near the fire shutter. An electronic valve (21) that is operated by receiving a signal from; It is characterized by having a nozzle (22) inserted into each capillary water channel.
이러한 전자밸브는 오작동을 방지하기 위해서 방화셔터부근에 설치된 복수의 열감지센서가 동시에 작동될 경우에만 작동된다.To prevent malfunction, this electronic valve operates only when multiple heat sensors installed near the fire shutter operate simultaneously.
상기 셔터부(3)는 , 도 1과 도 2에서 도시된바와 같이, 스라트 또는 방화코팅된 실리카천으로 된 방화막으로서, 화염과 연기가 확산됨을 방지하는 기능 이외에 방화셔터의 인접지역에 대한 복합열 급증을 억제하기 위해서, 즉 차열성능을 구현하기 위해서 셔터부의 일면에 복수의 모세물길통(31)들이 형성됨을 특징으로 한다.As shown in FIGS. 1 and 2, the shutter unit 3 is a fire barrier made of slat or fire-retardant coated silica cloth, and in addition to preventing the spread of flame and smoke, it protects against the area adjacent to the fire shutter. In order to suppress the rapid increase in complex heat, that is, to implement heat shielding performance, a plurality of capillary channels 31 are formed on one surface of the shutter part.
상기 모세물길통(31)의 구성은 셔터부의 일면에 방화코팅된 실리카천으로 이루어진 복수의 덧판을 이용하여, 하측덧판(322,323)의 상단은 상측덧판(32,321)의 하단을 삽입한 상태로 배열한 후, 가로방향으로 일정한 간격을 두고 수직방향으로 바느질하거나, 박판재를 이용하여 셔터부에 결합시킴으로서, 셔터부 일면과 덧판의 일면 사이와 바느질선(33,331)으로 구성되어 형성되며, 투입된 물이 아래로 흐르게 하는 모세물길의 통을 이룬다.The configuration of the capillary water channel 31 uses a plurality of overlays made of silica cloth coated with a fireproof coating on one side of the shutter part, and the upper end of the lower overlays 322 and 323 is arranged with the lower end of the upper overlays 32 and 321 inserted. Afterwards, it is sewn vertically at regular intervals in the horizontal direction or joined to the shutter part using a sheet material, so that it is formed between one side of the shutter part and one side of the back plate and a sewing line (33,331), and the injected water flows downward. It forms the barrel of the Moses waterway that flows.
이러한 모세물길통의 역할은 물 공급관의 노즐을 통해 투입되는 물이 외부로 새는 것을 방지하고, 모세관현상에 의하여 얇은 틈새사이로 넓게 펴지게 함으로서, 방화막의 일면 전체를 고르게 수막을 형성하는 역할을 한다.The role of this capillary water channel is to prevent the water injected through the nozzle of the water supply pipe from leaking out and to spread it widely through thin gaps through capillary action, thereby forming a water film evenly over the entire surface of the fireproof membrane.
또한, 화재가 급속히 진행되어 셔터부 일면에 가해지는 열량이 증가할수록 넓은 수막의 증발현상을 가속화시켜서 복사열 발생을 억제하는 한편, 급증하는 수증기 압력으로 모세물길통의 틈새 즉 셔터부 일면과 덧판사이의 틈새가 확장하게 되어 투입된 물이 신속하게 낙하하면서 셔터부의 하부로 물 공급을 원활하게 하는 역할도 한다.In addition, as the fire progresses rapidly and the amount of heat applied to one side of the shutter increases, the evaporation phenomenon of the wide water film is accelerated to suppress the generation of radiant heat, while the rapidly increasing water vapor pressure causes the gap in the capillary water channel, that is, between one side of the shutter and the back plate, to be closed. As the gap expands, the injected water falls quickly, which also serves to smooth the supply of water to the lower part of the shutter.
그리고 상측 덧판의 하단을 하측 덧판의 상단에 삽입하여 겹쳐지도록 구성 바느질함은 수증기 배출구를 형성시키고, 형성된 배출구를 통하여 수증기 배출을 원활하게 하면서 아래로 흐르는 물이 하측 덧판 내부로 유입되도록 하여, 모세물길통의 내부에 수증기압이 급증하여 모세물길통이 부풀어 오르는 것을 방지하고, 셔터부의 하부까지 원활한 물 공급과 모세관현상을 활성화 시키는 역할을 한다.And the bottom of the upper back plate is inserted into the top of the lower back plate so that it overlaps. The sewing box forms a water vapor outlet, and facilitates the discharge of water vapor through the formed outlet while allowing the water flowing downward to flow into the inside of the lower back plate, creating a capillary water path. It prevents the capillary water channel from swelling due to a rapid increase in water vapor pressure inside the barrel, and serves to smoothly supply water to the lower part of the shutter and activate the capillary phenomenon.

이러한 셔터부에 결합된 롤러는 셔터부가 완전히 펼쳐질 때 셔터부의 중간부위에 위치하게 됨으로서 풍압의 영향을 차단하면서, 각각의 모세물길통으로 흘러내리는 물을 일시적으로 저장하고, 저장된 물을 물길홈을 통해서 재분배하여 아래 모세물길통으로 재투입하는 핵심 기능을 구현 한다.The roller coupled to this shutter unit is located in the middle of the shutter unit when the shutter unit is fully unfolded, thereby blocking the influence of wind pressure, temporarily storing water flowing down into each capillary water channel, and redistributing the stored water through the water channel groove. This implements the core function of re-injecting water into the capillary water channel below.
