Composite fireproof door
The invention discloses a composite fireproof door which comprises a door leaf, a door frame and hinges. The door leaf comprises a frame body formed by a faceplate, a backplate and two side plates, fireproof frameworks are arranged at positions, close to the side plates, in the frame body, a cavity formed by the faceplate, the backplate and the fireproof frameworks is filled with inorganic fireproof core material plates, the door frame is filled with fireproof plates and multilayer plates which are distributed alternately and bonded through high-temperature-resistant glue, and section of the door frame is in the shape of a step; when the door leaf is closed, two sides of the door leaf are positioned in the step of the door frame, so that the door leaf is integrally embedded in the door frame. Heat insulating performance can be improved, and deformation can be avoided, so that fireproof performance is improved.
