본 발명은 방화셔터용 비상자동잠금장치에 관한 것으로서, 보다 상세하게는 화재 발생시 방화셔터의 비상탈출문이 자연적으로 개방되는 것을 방지하여 화염과 연기 등이 확산되는 것을 방지하는 방화셔터용 비상자동잠금장치에 관한 것이다.The present invention relates to an emergency automatic locking device for a fire shutter, and more particularly, an emergency automatic lock for a fire shutter to prevent the spread of flames and smoke by preventing an emergency escape door of the fire shutter from being naturally opened when a fire occurs. Relates to a device.

일반적으로 방화셔터는 건축물 내부에 설치되는 것으로, 평상시에는 특정 공간 내부로 외부사람이 진입하는 것을 차단하는 셔터의 역할을 하는 반면, 화재가 발생되는 경우에는 화염, 연기, 유독가스 등이 확산되는 것을 방지하는 역할을 하게 된다. 따라서 일정 규모 이상의 건물에는 소방법에 의해 그 설치가 의무화되어 있다.In general, a fire shutter is installed inside a building, and normally serves as a shutter to prevent outsiders from entering a specific space. In the event of a fire, flame, smoke, and toxic gas are spread. To prevent it. Therefore, it is mandatory to install the building more than a certain size by fire method.

특히, 대구지하철 화재참사나 각종 건물의 화재사건에서 보는 바와 같이, 건물 내부에서 화재가 발생될 경우, 화염과 연기는 인명피해와 물적피해를 확대시키는 주된 원인이 되었다. 따라서 화재발생으로 인한 인명피해와 물적피해를 최소화 하기 위해서는 무엇보다 방화셔터의 화염 및 연기의 확산을 방지하기 위한 차단기능이 매우 중요한 요소로 인식되고 있는 실정이다.In particular, as shown in the Daegu subway fire disaster or fire events in various buildings, fire and smoke were the main causes of the expansion of human and physical damages. Therefore, in order to minimize human and material damages caused by fire, the blocking function for preventing the spread of flame and smoke of fire shutters is recognized as a very important factor.

도 1은 이와 같은 종래의 방하셔터를 나타낸 것으로, 도시한 바와 같이 종래의 방화셔터(100)에는 비상탈출문(200)이 경첩(300)에 의해 개폐 가능하게 설치되며, 이러한 비상탈출문(200)은 출입구나 비상탈출구로 사용되면서 화재발생시에는 화염과 연기의 확산을 차단하게 된다.1 illustrates such a conventional discharge shutter, and as shown, an emergency escape door 200 is installed to be opened and closed by a hinge 300 in the conventional fire shutter, and such an emergency escape door 200 is shown. ) Is used as an entrance or emergency exit to block the spread of flame and smoke in case of fire.

그러나 종래의 방화셔터(100)는 화재가 발생될 경우, 화염에 의해 고온으로 가열되어 방화셔터(100) 뿐만 아니라 방화셔터(100)의 비상탈출문(200)도 열 변형되며, 이 과정에서 비상탈출문(200)에 설치된 경첩(300) 내부의 스프링(미도시)과 같은 부품들이 녹거나 심하게 변형 및 파손되어 비상탈출문(200)이 저절로 개방되는 문제점이 발생되었다.However, if a fire occurs in the conventional fire shutter 100, the fire is heated to a high temperature by the flame, and not only the fire shutter 100 but also the emergency exit door 200 of the fire shutter 100 is deformed, and in this process Parts such as springs (not shown) inside the hinge 300 installed in the escape door 200 is melted or severely deformed and broken, causing the emergency escape door 200 to open by itself.

따라서 종래에는 비상탈출문(200)의 개방으로 인해 연기 및 화염이 확산되므로 심각한 인적피해와 물적피해를 초래하는 등 방화셔터(100)의 방화 및 차연 성능을 현저하게 저하시키는 치명적인 문제점이 발생되었다.Therefore, in the related art, since the smoke and flames are spread due to the opening of the emergency exit door 200, a serious problem occurs that significantly lowers the fire protection and the smoke insulation performance of the fire prevention shutter 100, such as causing serious human damage and material damage.
