Abstract:
The present invention relates to a fireproof door and a fireproof door frame, and more particularly, to a fireproof door and a fireproof door frame which permit water to flow along the interiors thereof to block heat, and which permit the gap formed between the door frame and the door to be sealed to prevent toxic gases from entering an indoor area upon outbreak of fire. The fireproof door according to the present invention comprises a water accommodating unit, a groove, a water-swelling body, a suction port and a plurality of supply holes. The water accommodating unit is formed to accommodate water therein. The groove is formed along a door rim. The water-swelling body is inserted into the groove along the door rim such that the water-swelling body swells upon absorbing water and seals the gap formed between the door frame and the door. The suction port is formed in a lower portion of the fireproof door so as to supply water to the water accommodating unit. The supply holes are formed along the groove such that the supply holes penetrate from the water accommodating unit to the water-swelling body, so as to supply water accommodated in the water accommodating unit to the water-swelling body through the suction port. The fireproof door frame according to the present invention comprises a water accommodating unit, a groove, a water-swelling body, a suction port and a plurality of supply holes. The water accommodating unit is formed to accommodate water therein. The groove is formed along a door frame rim. The water-swelling body is inserted into the groove along the door frame rim such that the water-swelling body swells upon absorbing water and seals the gap formed between the door frame and the door. The suction port is formed in a lower portion of the fireproof door frame so as to supply water to the water accommodating unit. The supply holes are formed along the groove such that the supply holes penetrate from the water accommodating unit to the water-swelling body, so as to supply water accommodated in the water accommodating unit to the water-swelling body through the suction port.
