본 발명은 도어클로저의 닫힘보조장치에 관한 것으로서, 보다 상세하게는 제연구역 내 방화문의 도어클로저 저면에 설치됨으로써, 화재발생시 제연구역의 방화문을 신속하게 닫기 위해 설치한 도어클로저의 닫힘작동을 신속하고 원활하게 작동시키는 제연구역 내 방화문의 도어클로저 닫힘보조장치에 관한 것이다.The present invention relates to a closing assist device of a door closer, and more particularly, to be installed on the bottom of the door closer of the fire door in the smoke control area, thereby quickly closing the operation of the door closer installed to close the fire door of the smoke control area in the event of a fire. A door closer closing aid of a fire door in a ventilation area which operates smoothly.

일반적으로 아파트나 병원등의 건물에는 현행법상 제연설비가 필수적으로 설치되어 있으며, 상기 제연설비는 최초 화재발견시 연기감지기에 의해 종합 방제실에 화재발생 신호가 전달되면 화재가 발생된 구역의 비제연구역과 제연구역과의 압 력차이를 50Pa(40~60)로 자동유지시켜 화재의 확산을 방지하고 비상계단등 대피통로를 마련하기 위한 설비이다. 이때, 제연구역내의 방화문에 설치되는 도어클로저의 경우는 통상적으로 연기감지 도어클로저로써 화재발생시 연기감지기에 의해 즉시 닫히는 방식으로 설치되어 있다.In general, smoke control facilities are installed in buildings such as apartments or hospitals, and the smoke control system is a non-research study of the area where the fire occurred when a fire occurrence signal is transmitted to the comprehensive control room by the smoke detector when the fire is first detected. The pressure difference between the station and the smoke control area is automatically maintained at 50 Pa (40 ~ 60) to prevent the spread of fire and to prepare for escape routes such as emergency stairs. In this case, the door closer installed in the fire door in the smoke control area is typically installed as a smoke detection door closer in a way that is immediately closed by the smoke detector when a fire occurs.

그러나, 제연구역 내 방화문이 개방된 상태에서 화재가 발생하여 방화문에 설치된 도어클로저가 연기감지기에 의해 닫힘작동을 한 때에 비제연구역과 제연구역과의 압력차이(50Pa(40~60))를 유지시키기 위해 급기댐퍼에서 배출되는 바람(방연풍속0.7m/s)의 영향으로 방화문이 온전히 닫하지 못하는 문제가 발생하고 방화문이 온전히 닫히지 못하게 되면 제연구역형성을 제대로 할 수가 없어서 제연구역에서 발생되는 유독가스가 전층으로 확산되어 비상계단으로의 대피통로 확보에 문제가 생기게 되고 이로 인해 유독가스로 인한 인명사고를 막을 수 없는 큰 문제점이 생기게 되는 것이다.However, when the fire occurs in the open fire door in the smoke control area and the door closer installed in the fire door is closed by the smoke detector to maintain the pressure difference (50Pa (40 ~ 60)) between the non-smoke control area and the smoke control area. If the fire door does not close completely due to the wind discharged from the air supply damper (flame wind speed 0.7m / s), and if the fire door is not closed completely, it is impossible to form the smoke control area and toxic gas generated in the smoke control area It spreads to all floors and causes a problem of securing an escape route to the emergency stairs, which causes a big problem that cannot prevent human accidents caused by toxic gases.

본 발명의 목적은 가이드에 고정된 스프링이 연결구에 의해 작동부와 연결형성되어 제연구역에 사용되는 도어클로저 본체의 저면에 설치됨으로써 화재발생시 제연구역 내 급기댐퍼에서 배출되는 바람의 압력을 이기고 방화문을 닫아 유독가스를 신속하고도 쉽게 차단시켜 큰 인명피해를 미연에 방지할 수 있는 제연구역 내 방화문의 도어클로저 닫힘보조장치를 제공함에 있다.An object of the present invention is formed on the bottom surface of the door closer body used in the ventilation area by the spring fixed to the guide is connected to the operation portion by the connector to overcome the pressure of the wind discharged from the air supply damper in the ventilation area in the event of a fire to open the fire door In order to close the toxic gas quickly and easily, it is possible to provide a door closer closing assistance device of the fire door in the smoke control area that can prevent a great loss of life.
