Steel-wood heat insulation fireproof door and manufacturing method thereof

Abstract

The invention provides a steel and wood heat-insulating fireproof door, which comprises a door frame and a door leaf. The door frame is hinged with the door leaf through fireproof hinges; the door leaf includes a skeleton; the skeleton is filled with expanded perlite fireproof board; the surface of the expanded perlite fireproof board is wrapped with the first magnesium silicon fireproof board in turn, and a L Shaped fireproof expansion seal; the door frame is fixed with a second magnesium-silicon fireproof board on the inner side of the fire-receiving surface; a door gap seal is also set between the door leaf and the door frame. The door leaf is 2214mm high, 55mm thick and 914mm wide. The expanded perlite fire-proof board is installed inside the door leaf to improve the fire-proof effect, and the magnesium-silicon fire-proof board is installed to further improve the fire-proof effect and at the same time improve the strength and impact resistance of the door leaf. By properly installing the L-shaped fireproof expansion seal on the door frame, the effect of sealing and fire prevention can be improved and the noise generated between the door leaf and the door frame can be reduced when the door leaf is closed.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a steel and wood heat-insulated fire door and a manufacturing method thereof. 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 defici...
