More Information
Summary:The present invention relates to a fire door that blocks a gap between two door panels when the fire door is closed due to a fire, so as to prevent propagation of flame or smoke to the opposite side, and prevents door opening due to a gap between the two door panels formed by pressing force (suction force) caused by flame or hot blast. The fire door of the present invention includes a door frame (100), first and second door panels (200, 300), first windshield parts (400, 600), and second windshield parts (500, 700). 본 발명은 화재로 방화문이 닫혔을 경우 양 문짝 사이의 틈을 막아주어 화염이나 연기가 반대편으로 전파되는 것을 차단할 수 있고, 화염이나 열풍에 의해 발생되는 가압력(흡입력)으로 양 문짝 사이가 벌어져 방화문이 열리는 것을 막아주는 방화문에 관한 것이다.
