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
[0029] 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:
[0030] Such as figure 1 , figure 2 As shown, the novel wooden heat-insulated and fireproof composite door includes a door frame 1, a child 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 .

The invention provides a novel wooden heat-insulation and fire-proof main and auxiliary door. The novel wooden heat-insulation and fire-proof main and auxiliary door comprises a door frame, an auxiliary door and a main door, wherein the auxiliary door and the main door are symmetrically and fixedly arranged on edge frames at the two sides of the door frame by fireproof hinges; a door leaf comprises a skeleton; an expanded perlite fireproof plate is filled into each skeleton; a first magnesium and silicon fireproof plate and a flame retardant plywood are sequentially and fixedly arranged on the surface of each expanded perlite fireproof plate; a fireproof expansion sealing part is arranged between the door frame and each door leaf; a second magnesium and silicon fireproof plate is fixedly arranged at the inner side of the fire receiving surface of the door frame; the auxiliary door and the main door are closed by a tongue-and-groove type. The novel wooden heat-insulation and fire-proof main and auxiliary door has the advantages that by arranging the expanded perlite fireproof plates in the door leaves, the fireproof effect is improved; by arranging the magnesium and silicon fireproof plates, the fireproof effect is further improved, and the strength and impact-resistant capability of the door leaves are improved; by reasonably arranging the fireproof expansion sealing parts 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 novel wooden heat-insulating and 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 pr...
