Problems solved by technology

[0003] At present, the fire doors used in densely populated places, homes, and clubs have a high thermal conductivity. When a fire occurs, the temperature of the door leaf is likely to be too high, resulting in the door leaf being easily deformed and failing to meet the requirements of fire performance. In addition, the strength of traditional fire doors Poor, its impact resistance also needs to be improved

Embodiment Construction

[0028] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0029] Such as figure 1 , figure 2 As shown, a wooden heat-insulated and fireproof composite door includes a door frame 1, a sub door 2a, and a mother door 2b; The sub-door 2a and the parent door 2b have the same structure. The door leaf 2 includes a framework 21 around the door leaf and an inner framework 22 of the door leaf; the framework 21 around the door leaf is divided into multiple regions by the inner framework 22 of the door leaf. Expanded perlite fireproof boards 23 are filled in multiple areas to form a door core, a first magnesium-silicon fireproof board 24 is fixed on the surface of the door core, and a flame-retardant plywood 25 is fixed on the surface of the first magnesium-silicon fireproof board 24 .

Abstract

The invention provides a wooden heat-insulation fireproof primary-secondary door, which comprises a door frame, a secondary door and a primary door. The secondary door and the primary door are symmetrically fixedly arranged on borders on the two sides of the door frame through fireproof hinges. A door leaf comprises skeletons; expanded perlite fireproof boards are arranged in the skeletons; a first magnesium-silicon fireproof board and inflaming-retarding veneer boards are fixedly arranged on the surfaces of the expanded perlite fireproof boards in sequence. A fireproof expansion sealing member is arranged between the door frame and the door leaf; a second magnesium-silicon fireproof board is fixedly arranged on the inner side of the exposed-to-fire surface of the door frame; the secondary door and the primary door are closed by adopting a rabbet. Through arranging the expanded perlite fireproof boards inside the door leaf, the fireproof effect is improved; the strength and the impact resistance capacity of the door leaf are improved while the fireproof effect is further improved by arranging the magnesium-silicon fireproof boards. Through reasonably mounting the fireproof expansion sealing member on the door frame, the sealing fireproof effect is improved.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a wooden heat-insulating fire-proof composite door. Background technique [0002] With the country's large-scale infrastructure construction (such as subways, expanded airports and stadiums), the demand for fire doors used in buildings is increasing, the performance requirements are getting higher and higher, and the fire protection alert level requirements are getting higher and higher. [0003] At present, the fire doors used in densely populated places, homes, and clubs have a high thermal conductivity. When a fire occurs, the temperature of the door leaf is likely to be too high, resulting in the door leaf being easily deformed and failing to meet the requirements of fire performance. In addition, the strength of traditional fire doors Poor, its impact resistance also needs to be improved. Contents of the invention [0004] Aiming at the deficiencies of the prior art, t...
