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] like figure 1 , figure 2 As shown, a split 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 stop line, and ...

Abstract

The invention provides a double-side opening type wooden heat insulation fireproof door, comprising a door frame and two door leaves, wherein the two door leaves are symmetrically fixed on side frames at the two sides of the door frame respectively by fireproof hinges; each door leaf comprises a framework; each framework is internally filled with an expanded perlite fire prevention board, and a first magnesium-silicon fire prevention board and a flame-retardant plywood are sequentially fixed on the surface of each expanded perlite fire prevention board; a fire-proof expansion sealing element is arranged between the door frame and each door leaf; a second magnesium-silicon fire prevention board is fixed at the inner side of a surface, exposed to fire, of the door frame; the two door leaves are closed in a tongue-and-groove way. The expanded perlite fire prevention boards are arranged in the door leaves, so that a fireproof effect is improved; the magnesium-silicon fire prevention boards are arranged, so that the strength and impact resistance of the door leaves are improved while the fireproof effect is further improved. The fire-proof expansion sealing elements are reasonably installed on the door frame, so that a sealing fire prevention effect is improved.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a split 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, the inventi...
