Thermal insulation fireproof steel-wood door
The invention discloses a thermal insulation fireproof steel-wood door which comprises a door frame and a door leaf. The door frame is hinged to the door leaf through fireproof hinges. The door leaf is provided with plywood, a glass fibre and magnesium cement board and an expanded perlite fireproof plate from outside to the center in the thickness direction. The plane dimension of the expanded perlite fireproof plate is smaller than the plane dimension of the plywood and the plane dimension of the glass fibre and magnesium cement board. Flame retardant wood is arranged around the expanded perlite fireproof plate. The cross sections of four edge frame bodies of the door frame are all in an L shape. The door leaf is limited by the L-shaped door frame in a closed state. L-shaped fireproof expansion sealing elements matched with the L-shaped door frame are arranged between the door frame and the door leaf. Compared with the prior art, the thermal insulation fireproof steel-wood door has the advantages of being high in strength, good in fireproof performance and capable of effectively avoiding deformation of the door leaf.
