Noninflammable gasket installing structure of automatic door
The present invention relates to a structure for installing a nonflammable gasket of an automatic airtight firefighting door, which mounts a support plate in the nonflammable gasket to support an end portion at one side of the nonflammable gasket and mounts a magnet at a predetermined interval in the door, an upper door frame and a side door frame to fix the nonflammable gasket to the door, the upper door frame and the side door frame to be detachable, respectively, so that assembling properties can be improved. The structure for installing a nonflammable gasket of an automatic airtight firefighting door pressurizes the nonflammable gasket to an outer side of the door while a cam is rotated by pressurization of a pressurizing rod when the automatic door is closed, thereby having more improved sealing power to effectively prevent harmful gas from being introduced.
본 발명은 불연 개스킷의 내부에 지지판체를 장착하여 불연 개스킷의 일측 단부를 지지하도록 하고 도어와 상부문틀 및 측면문틀의 내부에 일정 간격으로 자석을 장착하여 불연 개스킷을 도어와 상부문틀 및 측면문틀에 각각 착탈 가능하게 고정시키므로 조립성이 향상되고, 자동문을 폐쇄할 때, 가압봉의 가압에 의해 캠이 회전하면서 불연 개스킷을 도어의 외측으로 가압하므로 밀폐력이 한층 향상되어 유독가스의 유입을 효과적으로 차단하는 기밀 방화 자동문의 불연 개스킷 설치구조에 관한 것이다.
