The fire protection device is installed in the door.

즉 화재가 발생하면 발생장소의 도어가 화재의 강한 열에 의하여 작동되는 방화장치에 의하여 자동으로 도어가 닫히어 불길의 번짐을 차단하므로서 화재의 피해를 최소화 시키고 있다.In other words, when a fire occurs, the door is automatically closed by the fire protection device operated by the strong heat of the fire to block the spread of the fire, thereby minimizing the damage of the fire.

그러나 종래의 방화장치는 도어를 개폐시키도록 연결한 긴 로드에 설치되도록 하고 있어 노출범위가 넓어 외부물에 의한 접촉 등으로 파손될 우려도 있고, 구조적으로 복잡하여 오작동 및 고가로 인하여 적용에 기피하거나 작동을 해지시키어 놓는 사례가 많는 등의 문제점이 있었다.However, the conventional fire protection device is to be installed on a long rod connected to open and close the door, so the exposure range is wide, there is a risk of damage due to contact by external objects, etc., structurally complicated to avoid or operate due to malfunction and expensive There have been many problems such as a lot of cases.

또한 최근 개발된 유압식의 로드가 없는 도어클로져에는 적용이 불가능한 등의 문제점이 있었다.In addition, there was a problem such as not applicable to the recently developed door closer without a hydraulic rod.

본 고안의 목적은 로드가 없는 유압식 도어클로져에 적합하도록 하면서 구성의 단순화로 고장율을 극소화 시키고 단가를 낮추어 활용도를 높이도록 한 방화용 도어클로저를 제공함에 있다.It is an object of the present invention to provide a fire door door closer that is suitable for a hydraulic door closer without a rod while simplifying the configuration to minimize the failure rate and lower the unit cost to increase the utilization.

When the door is opened, the body 6 of the fire protection device fixed by the band 7 to the housing 2 moves together to protrude to one side by the rotation of the housing 2. (6) The roller (9), which is connected to the stopper (8) at the top, forcibly pushes the elastic plate (5) located at the top of the hinge (4 ') by artificial force, and the door is completely opened and the door is pulled out. When it is released, the door is returned to its original position by the self-rotating force of the door closer (1). At this time, the stopper (6) does not push the elastic plate (5) by its own force, so the door is not closed but opened. When the door is normally opened and artificially pulls the door, the stopper 8 extends and closes the elastic plate body 5. These open doors are mainly applied to passage doors, doors leading to stairs, and the like.

문을 오픈 상태에서 화재가 발생시 화재 발생위치에 있는 방화용 문은 화재시 발생되는 뜨거운 열이 문에 직접 접촉 또는 전달되면 도어클로져(1)의 한측 바디(6)내에 설치된 작동판체(12)의 타측단에 설치된 휴즈(13)가 열에 의해 녹아 끊어짐에 따라 스프링(14)의 탄력에 의하여 한측의 리벳(17)을 중심으로 두 판체가 벌어지므로서 작동판체(12)에 의해 받혀지는 스톱퍼(8)가 받침이 해제와 함께 조립공(61)의 하부에 위치한 스프링(16)의 당김으로 인하여 하방으로 내려가게 됨에 따라 도어클로져(1)의 자체 회동력을 제어하도록 탄성판체(5)를 걸리게 하고 있는 스톱퍼(8)의 기능이 해제됨으로서 문은 자동으로 닫히게 되어 불길의 번짐을 차단하여 화재의 피해를 최소화 시킬 수 있게 되는 것이다.When the fire occurs when the door is open, the fire door is located at the fire occurrence position of the operating plate 12 installed in the one side body 6 of the door closer 1 when hot heat generated during the fire is directly contacted or transmitted to the door. As the fuse 13 installed at the other end is melted and broken by heat, a stopper 8 supported by the operating plate body 12 as two plates are opened around the rivet 17 on one side by the elasticity of the spring 14. As the support is released and descends downward due to the pulling of the spring 16 located at the lower part of the assembly hole 61, the elastic plate body 5 is held to control the self-rotating force of the door closer 1. As the function of the stopper 8 is released, the door is automatically closed to block the spread of the flame to minimize the damage of the fire.
