피난계단 전실(32)에 설치되는 제연설비(1)는 연기 감지기 등에 의하여 화재발생이 감지되면 연기가 피난계단실(33)로 유입되는 것을 방지하기 위해 작동된다. 소방법에 따르면, 피난계단실(33)과 피난계단 전실(32)의 차압은 40∼60파스칼로 유지되도록 규정하고 있다. 즉 피난계단실(33)의 기압을 피난계단 전실(32)의 기압보다 높게 유지하여 연기가 피난계단실(33)로 유입되지 않도록 하고 있다.The smoke control system 1 installed in the evacuation stairs front chamber 32 is operated to prevent smoke from entering the evacuation stairs chamber 33 when a fire occurrence is detected by a smoke detector or the like. According to the fire law, the differential pressure between the evacuation step chamber 33 and the evacuation step front chamber 32 is maintained to be maintained at 40 to 60 pascals. That is, the air pressure of the evacuation stairs chamber 33 is kept higher than the air pressure of the evacuation stairs front chamber 32 so that smoke does not flow into the evacuation stairs chamber 33.
또한 법규상으로 피난계단실의 구조는, 차압유지를 위하여 피난계단실 출입문은 항상 닫혀있는 상태로 유지되어야 하고,출입 후에는 반드시 닫혀지도록 되어야 한다고 명시되어 있다.In addition, the law states that the structure of the evacuation stairs should be kept closed at all times and must be closed after entering.
그러나 이와 같은 피난계단실 구조는 건물에 화재가 발생하였을 시에 피난계단실로 연기가 들어와 피난계단 역할을 제대로 하지 못하는 구조적인 문제점을 가지고 있다. However, such a structure for evacuation stairs has a structural problem in that when the fire occurs in the building, smoke enters the evacuation stairs and does not function properly as an evacuation stairs.
즉 화재가 발생하면 엘리베이터 운행은 물론, 전기로 작동되는 모든 안전 시스템 대부분이 그 기능을 상실하게 되어 시설물을 이용하지 못하게 되고, 피난하기 위한 수단과 피난처는 피난계단실(33)밖에 없게 된다. That is, when a fire occurs, most of the safety systems operated as well as the electric power will lose its function, and the facilities will not be available, and there will be only a means for evacuation and a shelter 33 for evacuation.
또한 많은 사람들이 동시에 피난하기 위해서는 피난계단실(33)의 출입구(33a)가 지속적으로 장시간 동안 개방되어야만 한다. 즉 피난계단실의 출입문이 닫혀있지 않고 열려있는 시간이 길어져야 하기 때문에, 화재가 발생한 층의 피난계단실과 피난계단 전실 사이에 차압이 유지하지 못하게 되어, 피난계단실(33)로 연기가 들어 오게 된다. 이에 피난계단실(33)은 연기가 차게 되고, 상부층으로 확산되어 피난계단실 전체가 마치 굴뚝처럼 되는 구조적인 문제점이 있었다. 종래의 제연설비의 문제점은 빈번하게 반복되는 대형 화재현장이 이를 증명해주고 있다. In addition, in order for many people to evacuate at the same time, the doorway 33a of the evacuation stairs 33 must be continuously opened for a long time. That is, because the door of the evacuation stairs is not closed and the open time has to be lengthened, the differential pressure cannot be maintained between the evacuation stairs room and the entire evacuation stairs on the floor where the fire has occurred, and the smoke enters the evacuation stairs room 33. As a result, the evacuation stair chamber 33 is filled with smoke, and there is a structural problem in which the entire evacuation stair chamber is like a chimney. The problem of the conventional smoke control facility has been proved by a large fire site that is frequently repeated.
또한 많은 사람들이 긴박한 상황에서 계단을 이용하기 때문에, 계단에서 미끄러지거나 넘어지는 경우가 발생하여 제2의 안전사고 발생위험이 있었다. In addition, since many people use the stairs in an urgent situation, there is a risk of a second safety accident due to slipping or falling on the stairs.
또한 화재 발생층의 상부층에 있는 사람들이 하부층으로 피난하기 위해서는 화재 발생층의 피난계단실(33)의 계단(33b,33c)을 통과해야만 하는 어려움이 있었다.In addition, in order for people in the upper floor of the fire generating layer to evacuate to the lower floor, there is a difficulty of passing through the stairs 33b and 33c of the evacuation stairs 33 of the fire generating layer.
본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 화재가 일어난 층에서 발생된 연기가 피난계단실로 들어와 연기로 가득 차게 되고, 이 연기가 상부층으로 확산되는 것을 막는 것이다. The present invention is to solve the above problems, the smoke generated in the fire layer is to enter the evacuation stair chamber filled with the smoke, to prevent the smoke from spreading to the upper layer.
또한 긴급 피난시에 계단의 근본적인 구조적 한계로 인하여 사람들이 안전하고 신속하게 피난할 수 없는 현재의 피난계단실 구조를 해결하려는데 그 목적이 있다. It also aims to solve the current evacuation stairs structure, which people cannot evacuate safely and promptly due to the fundamental structural limitations of the stairs during emergency evacuation.

도 19 는 본 발명에 따른 개폐구의 일 예를 개략적으로 도시한 도면이다. 19 is a view schematically showing an example of the opening and closing opening according to the present invention.
도시한 바와 같이, 본 발명에 따른 배기덕트는, 연기를 외부로 배출하는 말단, 예컨대, 건물옥상의 배기덕트 말단에 설치되는 개폐구(925f)를 포함할 수 있다. 개폐구는, 평상시에는 닫혀 있다가, 화재가 발생하여 연기가 계단실로 들어오게 되면 연기감지기에 의하여 개폐구가 개방되어 연기가 배출되도록 한 것이다.As illustrated, the exhaust duct according to the present invention may include an opening and closing hole 925f provided at an end for discharging smoke to the outside, for example, at the end of the exhaust duct on the building roof. The opening and closing opening is normally closed, but when a fire occurs and smoke enters the staircase, the opening and closing opening is opened by the smoke detector so that the smoke is discharged.

연기가 피난계단실로 들어오면, 연기감지기에 의하여 피난계단실 내에 설치된 배기덕트의 기능이 작동되기 시작한다. 건물옥상에 있는 배기덕트의 개폐구가 열리고, 각층 피난계단실의 연기차단부가 내려진다. 피난계단실로 들어온 연기는 연기차단부에 의하여 더 이상 상부층으로 올라가지 못하고 배기덕트의 연기유입구멍 속으로 빨려 들어가 옥상으로 상승한다. 배기덕트 속에는 송풍팬이 설치되어 연기 상승 속도를 더욱 빠르게 한다. 사람들이 피난계단을 이용하여 피난하는 중에 연기차단부 틈 사이로 들어온 소량의 연기는 상부층에 설치된 연기차단부에 의하여 더 이상 올라가지 못하고 대신 상부층의 배기덕트 속으로 흡입된다.When smoke enters the evacuation stairs, the function of the exhaust duct installed in the evacuation stairs is activated by the smoke detector. The opening and closing of the exhaust duct on the building roof opens, and the smoke blocking section of the evacuation stairs of each floor is lowered. The smoke entering the evacuation stair chamber is no longer taken up to the upper layer by the smoke blocking unit, but is sucked into the smoke inlet of the exhaust duct and rises to the rooftop. A blower fan is installed in the exhaust duct to speed up the smoke rise. When people evacuate using the evacuation stairs, a small amount of smoke that enters through the gap of the smoke blocking unit is no longer raised by the smoke blocking unit installed in the upper layer and is instead sucked into the exhaust duct of the upper layer.
