DEVICE FOR PREVENTING THERMAL DEFORMATION OF FIRE DOOR
According to the present invention, a device for preventing thermal deformation of a fire door comprises: a body unit installed in a coupling groove formed at one side of a fire door frame and forming a through hole in a vertical direction; a bimetal support unit having one side fixed to the body unit and the other side bent in a direction of the through hole to cover a lower side inlet of the through hole, and deformed in a direction in which the other side is moved away from the through hole as a temperature rises; and a fixing unit installed in the body unit to be inserted into a fire door by being exposed to a lower portion of the body unit by rotation when being deformed in a direction in which the bent other side of the bimetal support unit is moved away from the through hole as a temperature rises.
본 발명에 따른 방화문의 열변형 방지장치는 방화문 프레임의 일측에 형성된 체결홈에 설치되며, 상하 방향으로 관통홀을 형성하는 본체부; 일측이 본체부에 고정 설치되고, 타측이 관통홀 방향으로 밴딩되어 관통홀의 하측 입구를 덮으며, 온도의 상승에 따라 타측이 관통홀로부터 멀어지는 방향으로 형태가 변형되는 바이메탈 지지부; 및 바이메탈 지지부의 밴딩된 타측이 온도가 상승함에 따라 상기 관통홀로부터 멀어지는 방향으로 형태가 변형되면, 회전에 의해 본체부의 하방으로 노출되어 방화문으로 삽입되도록 본체부에 설치된 고정부;를 포함할 수 있다.
