An automatic closing device for fireproof door
The present invention is assembled between a door frame and a fireproof door in a link structure to provide closing force to the fireproof door. An automatic closing device for a fireproof door usually restrains the closing force of the fireproof door provided through a door closer main body to maintain an opened state of the fireproof door and releases restraint of the closing force when a fire occurs to form a pressure differential state of a smoke control area through closing of the fireproof door.
본 발명은 문틀과 방화문 사이에 링크구조로 조립되어 방화문에 폐쇄력을 제공하여, 평상시에는 도어 클로저 본체를 통해 제공되는 방화문의 폐쇄력을 구속하여 방화문의 개방상태를 유지하고, 화재 발생시 폐쇄력의 구속을 해제하여 방화문의 폐쇄를 통해 제연구역의 차압상태를 형성하도록 하는 방화문 자동 폐쇄장치에 관한 것이다.
