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
[0035] 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 drawings are used in conjunction with detailed descriptions, which are described as follows:
[0036] Such as figure 1 , figure 2 , Figure 7 As shown, a wooden heat-insulating fire-proof door includes a door frame 1 and two door leaves 2; the two door leaves 2 are symmetrically fixed on the side frames of the door frame 1 through fire-resistant hinges 3. The two door leaves 2 have the same structure. The door leaf 2 includes a frame 21 around the door leaf and an inner frame 22 of the door leaf; the frame 21 around the door leaf is divided into multiple areas by the inner frame 22 of the door leaf. From the thickness direction of the door leaf 2, the first magnesium-silicon fireproof board 24 of equal thickness is fixed on both sides of the framework 21 and 22, and then the expanded perlite fireproof board...

The invention provides a thermal insulation fireproof wood door. The thermal insulation fireproof wood door is characterized in that circumferential frameworks and door leaf inner frameworks are made of flame retardant wood; the circumferential frameworks are divided into a plurality of regions by the door leaf inner frameworks; in the thickness directions of door leaves, first magnesium-silicon fireproof plates in equal thickness are fixed at the two sides of the circumferential frameworks and the door leaf inner frameworks; expanded perlite fireproof plates are tamped in the plurality of regions; the thickness of the expanded perlite fireproof plates is equal to the thickness of the frameworks plus the thickness of the first magnesium-silicon fireproof plates at the two sides of the frameworks; first flame retardant plywood is fixed at the two sides of the common surfaces of the first magnesium-silicon fireproof plates and the expanded perlite fireproof plates; and a tongue and groove is also arranged at the sides coming into contact when the two door leaves are closed. The thermal insulation fireproof wood door has the beneficial effects that the fireproof effects are improved by arranging the expanded perlite fireproof plates inside the door leaves; the strength and impact resistance capacities of the door leaves are improved while further improving the fireproof effects by arranging the magnesium-silicon fireproof plates; and the sealing fireproof effects are improved by reasonably installing fireproof intumescent seals on a door frame.
Description
Technical field [0001] The invention relates to the technical field of fire doors, in particular to a wooden heat insulation fire door. Background technique [0002] With the country's large-scale infrastructure construction (such as subways, renewal and expansion of airports and stadiums), the demand for fire doors used in buildings is increasing, the performance requirements are getting higher and higher, and the requirements for fire protection levels are getting higher and higher. [0003] At present, fire doors used in densely populated places, homes, and clubs have high thermal conductivity. When a fire occurs, the temperature of the door leaf is likely to be too high, which causes the door leaf to be easily deformed and fails to meet the requirements of fire protection performance; in addition, the strength of traditional fire doors Poor, its impact resistance needs to be improved. Summary of the invention [0004] Aiming at the deficiencies of the prior art, the present inv...
