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

[0031] 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:

[0032] Such as figure 1 , figure 2 As shown, a double-opening wooden heat-insulating fire door includes a door frame 1 and two door leaves 2; The structures of the two door leaves 2 are identical. 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 .

[0033] The door frame 1 has a door sto...

Abstract

The invention provides a double-open wooden heat-insulating fireproof door. The double-open wooden heat-insulating fireproof door comprises a door frame and two door leaves; the two door leaves are symmetrically fixed to the frames on the two sides of the door frame through fireproof hinges. Each door leaf comprises a skeleton; the skeleton is filled with an expanded perlite fireproof plate; a first magnesium-silicon fireproof plate and flame-retardant plywood are fixed to the surface of each expanded perlite fireproof plate in sequence. A fireproof expansion sealing piece is arranged between the door frame and each door leaf; a second magnesium-silicon fireproof plate is fixed to the inner side of a fire facing surface of the door frame; the two door leaves are closed by adopting tongues and grooves. The fireproof effect is improved by arranging the expanded perlite fireproof plate in each door leaf; the fireproof effect is further improved by arranging the magnesium-silicon fireproof plates, and meanwhile, the strength and the impact resistance of the door leaves are improved. A sealed fireproof effect is improved by reasonably mounting the fireproof expansion sealing pieces on the door frame.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a double-opening wooden heat-insulating fire 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, th...
