Steel-wood fireproof door
The invention relates to a steel-wood fireproof door. The steel-wood fireproof door comprises a door body (1), wherein a cavity (2) is formed in the lower part of the door body (1); a gas box (3) is arranged on the rear half part of the cavity (2); the gas box (3) is filled with high-pressure gas; an operable gas door (4) is formed in the front part of the gas box (3); a plurality of gas discharging holes (5) are formed in the surface of the door body (1); when the gas door (4) is opened, a channel for flowing of high-pressure gas is formed between the gas door and the gas discharging holes (5). According to the steel-wood fireproof door, the gas box is arranged in the door body; the gas box is filled with the high-pressure gas; the high-pressure gas is stored in the gas box by sealing the gas box under a normal condition; the gas door of the gas box is opened and used for outwards discharging the high-pressure gas through the door body in danger, so that the high-pressure gas which is outwards discharged forms an external pushing force to smoke once the door is opened, and a large amount of smoke cannot be sucked by people during escaping, thus the precious time is gained for the escape of staff.
