Description

화재 발생시 자동문 개폐장치{Automatic door opening and closing device with fire emergency}Automatic door opening and closing device with fire emergency}

본 발명은 화재 등과 같은 비상상황이 발생시에 자동문이 자동으로 완전히 개방되어 대피자가 신속하게 대피할 수 있도록 하는 화재 발생시 자동문 개폐장치에 관한 것이다.The present invention relates to an automatic door opening and closing device in the event of a fire that allows the evacuee to evacuate quickly by automatically opening the automatic door automatically when an emergency such as a fire occurs.

일반적으로 도어는 사람이 출입하기 위한 출입문을 개폐하기 위한 것으로, 모터에 의해 자동으로 회전하는 회전문은 물론, 방화를 목적으로 사용되는 방화문 이나 비상상황시에 대피자가 용이하게 대피하기 위한 비상문 등 많은 종류로 건물 등에 사용되며, 건물의 벽체에 천공된 끝단에 사각의 틀 형태로 설치되는 도어틀, 해당 도어틀과 회전가능하게 결합하여 출입문을 개폐하기 위한 판 형상의 도어 및 해당 도어를 도어틀에 고정하여 출입문을 선택적으로 개폐할 수 있는 잠금수단이 통상적으로 사용된다.In general, the door is for opening and closing the door for people to enter and exit, as well as a revolving door that is automatically rotated by a motor, a fire door used for fire prevention purposes, or an emergency door for evacuators to evacuate in an emergency. Used as a kind of building, etc., a door frame installed in the form of a square frame at the end perforated in the wall of the building, a plate-shaped door for opening and closing the door by rotatably combining with the door frame, and the door to the door frame Locking means that can be fixed to selectively open and close the door is usually used.

특히, 비상문은 대피자가 용이하게 대피할 수 있게 여닫이 형태로 건물에 설치되며, 화재 등에 의한 비상상황시에 대피자는 도어를 밀어내어 계단이나 비상대피로를 통해 대피할 수 있도록 한다.In particular, the emergency door is installed in a casement type so that the evacuee can easily evacuate, and in case of an emergency due to a fire, the evacuator pushes the door to evacuate through a stairway or an emergency evacuation route.

그러나, 건물에 설치되는 여닫이 형태의 비상문은 평상시에 외부출입자를 차단하기 위해 잠금수단에 의해 잠궈진 상태를 유지하기에 비상상황이 발생시에 많은 인명피해를 유발하는 문제점으로 이야기 되고 있는 실정이다.However, the casement-type emergency door installed in the building is said to be a problem that causes a lot of human injury when an emergency occurs because it maintains a locked state by means of a locking means to block outsiders from entering.

이를 해결하기 위해 종래기술로 국내등록특허 제10-0685706호(공고일:2007.02.26.)가 개시되어 있으며, 상기한 종래기술은 화재 등의 비상상황이 발생시에 회전가능한 내측 비상문이 개방될 수 있도록 하여 대피자가 대피할 수 있도록 하는 기술이 개시되어 있다.In order to solve this, Korean Patent No. 10-0685706 (Publication Date: 2007.02.26.) has been disclosed as a prior art, and the above-mentioned prior art can open a rotatable inner emergency door when an emergency such as a fire occurs. Techniques for allowing evacuees to evacuate are disclosed.

그러나 이러한 종래기술은 비상문의 회전을 위해 해당 비상문의 상단과 끝단을 가로지는 회동축이 모터에 의해 회전하여 대피자가 용이하게 대피한다는 장점은 있으나, 비상문 자체가 양측으로 개방되는 구조를 가지고 있어 경황이 없는 비상상황에서 서로 대피하려는 대피자가 몰리는 경우, 또 다른 2차사고를 유발하는 문제점과 대피자의 인원에 따라 그 밀어내는 힘에 의해 비상문 자체가 파손될 소지가 있어 실적이지 못하다는 문제점이 있었다.However, this prior art has the advantage that the evacuator can evacuate easily by rotating the rotating shaft across the top and end of the emergency door to rotate the emergency door, but the emergency door itself has a structure that opens to both sides. If there were no evacuees trying to evacuate each other in this emergency, there was a problem that caused another secondary accident, and the emergency door itself could be damaged by the pushing force depending on the number of evacuees, so there was a problem that the performance was not good.

극내등록특허 제10-0685706호(공고일:2007.02.26.)Patent registration No. 10-0685706 (announcement date: February 26, 2007) 국내공개특허 제10-2015-34150호(공개일:2015.04.02.)Domestic Publication No. 10-2015-34150 (Publication date: 2015.04.02.)

상술한 종래의 문제점을 해결하기 위해 본 발명에 따른 화재 발생시 자동문 개폐장치는 비상상황이 발생시에 자동문이 완전히 개방될 수 있도록 하여 대피자가 대피시에 발생할 수 있는 2차 사고를 방지는 물론, 자동문 자체의 파손을 방지하고자 하는데 그 목적이 있다.In order to solve the above-described conventional problems, the automatic door opening and closing device in the event of a fire according to the present invention allows the automatic door to be completely opened in the event of an emergency to prevent secondary accidents that may occur during evacuation, as well as the automatic door itself. It is intended to prevent the damage of the purpose.

상기 구동모터(110)는 자동문 프레임(100)의 상부 일측으로 설치되어 외부의 전원으로 구동되며, 상기 구동모터(110)에는 브래킷 롤러(120)가 회전가능하게 장착된다.The driving motor 110 is installed on the upper side of the automatic door frame 100 to be driven by an external power source, and the bracket roller 120 is rotatably mounted to the driving motor 110.

상기 브래킷 롤러(120)에는 브래킷 롤러(120)를 감아도는 슬라이드 밸트(130)가 구비되며, 상기 슬라이드 밸트(130)에는 슬라이드 브래킷(미도시)이 고정되어 자동문(200)을 좌,우로 이동시키게 되며, 상기 자동문(200)은 하부에 형성된 바닥레일(140)을 따라 안내된다.The bracket roller 120 is provided with a slide belt 130 to wind the bracket roller 120, and a slide bracket (not shown) is fixed to the slide belt 130 to move the automatic door 200 to the left and right. And, the automatic door 200 is guided along the bottom rail 140 formed at the bottom.

또한, 실내의 임의의 위치에는 화재 감지설비(300)가 설치되어 있으며, 상기 화재 감지설비(300)는 구동모터(110)와 전기적으로 연결된다.In addition, a fire detection facility 300 is installed at an arbitrary location in the room, and the fire detection facility 300 is electrically connected to the driving motor 110.

상기 화재 감지설비(300)에는 화재로 인해 발생하는 연기 등에 의해 시야확보가 안될 경우 대피 경로 및 정보를 표시하는 표시부재(310)가 구비된다.The fire detection facility 300 is provided with a display member 310 for displaying evacuation routes and information when visibility is not secured due to smoke generated by a fire.

상기 화재 감지설비(300)에는 감지센서(320)가 장착되어 화재로 인한 연기를 감지할 경우 위험신호를 출력하게 되며, 화재 감지설비(300)에 내장된 제어부는 감지신호를 표시부재(310)에 전송하여 화재에 대처할 수 있는 정보 또는 대피 경로를 출력할 수 있게 제어하게 된다.The fire detection facility 300 is equipped with a detection sensor 320 to output a dangerous signal when detecting smoke caused by a fire, and the control unit built into the fire detection facility 300 displays a detection signal 310 It is controlled so that it can output information or evacuation routes that can cope with a fire by sending it to.

또한 상기 화재 감지설비(300)의 내측에는 일정 용량의 배터리(400)가 장착되어 구동모터(110)로의 전원공급이 중단되더라도 배터리(400)를 통해 전원을 공급할 수 있게 된다.In addition, a battery 400 of a certain capacity is mounted inside the fire detection facility 300 to supply power through the battery 400 even when the power supply to the driving motor 110 is stopped.

상기 자동문(200)은, 평상시에는 외부 전원을 이용하여 좌,우로 슬라이드 작동하게 되며, 화재가 발생하여 외부 전원에 문제가 되지 않을 경우 외부전원을 계속 이용하게 된다.The automatic door 200 slides to the left and right using an external power source in normal times, and continues to use the external power source if there is no problem with the external power source due to a fire.

또한, 화재 발생으로 인해 외부전원이 공급 중단 될 경우, 도 2에 도시된 바와 같이, 상기 자동문(200)은 구동모터(110)가 작동하지 않기 때문에 출입구를 개방할 수 없게 되며, 이러한 경우에는 화재 감지센서(300)에 장착된 배터리(400)를 통해 전원을 공급할 수 있게 된다.In addition, when the external power supply is interrupted due to a fire, as shown in FIG. 2, the automatic door 200 cannot open the doorway because the driving motor 110 does not operate. It is possible to supply power through the battery 400 mounted on the detection sensor 300.

상기 배터리(400)는 구동모터(110)와 전기적으로 연결되어 있으며, 평상시에는 전원스위치(500)를 통해 전기가 단락되어 구동모터(110)와의 전원을 차단하게 되며, 화재 발생시에는 감지센서(320)에서 화재를 감지하고 감지신호를 제어부에서 전달받아 전원스위치(500)를 전기적으로 연결하여 구동모터(110)와의 전원을 인가하게 된다.The battery 400 is electrically connected to the driving motor 110, and the electricity is shorted through the power switch 500 in normal times to cut off the power to the driving motor 110. In the event of a fire, the sensor 320 ) Detects the fire and receives the detection signal from the control unit to electrically connect the power switch 500 to apply power to the driving motor 110.

따라서, 화재 발생시 전원공급의 중단으로 자동문(200)이 작동하지 않더라도 배터리(400)의 전원을 이용하여 구동모터(110)를 구동으로 자동문(200)을 슬라이드시켜 출입구를 개방할 수 있어 대피자의 신속한 대피를 가능하게 하는 것이다.Therefore, even if the automatic door 200 does not work due to the interruption of the power supply in the event of a fire, it is possible to open the doorway by sliding the automatic door 200 by driving the driving motor 110 using the power of the battery 400. It is to enable rapid evacuation.
