The present invention relates to a fire door. A cylinder cover and a lock bolt cover are disposed and installed to be fixed to a right position in an inner frame installed in a fire door by using a position determination means so that any one of skilled or unskilled workers can easily work. In addition, the cylinder cover and the lock bolt cover inserted into the inner frame tightly adhere to a curved portion without interference. The lock bolt cover is configured to be fixed in a simple locking way, so it is possible to simply fix the lock bolt cover without a separate fixing means. Accordingly, cylinder position determination embossing and lock bolt position determination embossing are formed in the inner frame, respectively. A cylinder position determination hole inserted by the cylinder position determination embossing is formed in the cylinder cover installed in the inner frame. A lock bolt position determination hole inserted by the lock bolt position determination embossing is formed in the lock bolt cover installed in the inner frame.
본 발명은 방화문에 관한 것으로서, 방화문 내부에 설치된 내부프레임에 실린더커버와 꽂이쇠커버가 위치결정수단을 이용해 정위치에 배치된 후 고정되도록 설치하여, 숙련자 또는 비숙련자 상관없이 용이하게 작업할 수 있도록 하고, 또한 내부프레임으로 삽입되는 실린더커버와 꽂이쇠커버가 곡면부에 간섭없이 밀착되도록 하며, 아울러 꽂이쇠커버를 단순한 걸림방식으로 고정되도록 구성하여, 별도의 고정수단 없이도 간편하게 고정할 수 있도록, 내부프레임에 실린더위치결정엠보와 꽂이쇠위치결정엠보를 각각 형성하고, 그 내부프레임에 설치되는 실린더커버에는 상기 실린더위치결정엠보가 삽입되는 실린더위치결정구멍을 형성하고, 상기 내부프레임에 설치되는 꽂이쇠커버에는 꽂이쇠위치결정엠보가 삽입되는 꽂이쇠위치결정구멍이 형성된다.
