The present invention relates to a fire door system with improved airtightness. More specifically, the fire door system with the improved airtightness of the present invention improves airtightness while effectively blocking an accommodation space formed in a door frame when a fire door is closed. On the other hand, the fire door system with the improved airtightness is to prevent release of screws or bolts fixing a folded portion by preventing a load from being concentrated on the folded portion which rotationally connects the fire door to the door frame. The fire door system with the improved tightness comprises: the door frame (110); the fire door (120); the folded portion (130); and an airtight member (140).
본 발명은 기밀성이 향상된 방화문시스템에 관한 것으로써, 더욱 상세하게는 방화문의 닫힘시, 문틀프레임에 형성되는 수용공간이 효과적으로 차단되면서 기밀성이 향상되도록 하는 한편, 방화문을 문틀프레임에 회전 가능하게 연결하는 절첩부로의 하중이 집중되지 않도록 하여 절첩부를 고정하는 나사나 볼트 등의 이탈을 방지하기 위한 기밀성이 향상된 방화문시스템에 관한 것이다.
