Thermal-insulating combined fire door
The invention discloses a thermal-insulating combined fire door comprising a door leaf, a door frame and hinges. The door leaf comprises a frame, fireproof ribs are arranged within the frame near two side plates, and a chamber formed by a face plate, a back plate and the fireproof ribs is filled with an inorganic fireproof core plate. The section of the door frame is in a step form. When the door leaf is closed, the side plates of the door leaf are in contact with a concave face of the door frame, and the door leaf is wholly embedded into the door frame. The face, in contact with the door leaf, of the door frame is provided with a groove; the bottom of the groove is provided with thermal-insulating holes; a fireproof seal pad is disposed in the groove and raised from the groove. The thermal-insulating combined fire door is better in thermal insulation, deformation resistant and accordingly better in fire resistance.
