Heat-insulating fireproof steel door with door mirror

Abstract

The invention discloses a heat-insulating fireproof steel door with a door mirror. The door comprises a door frame and a door leaf. The door leaf is hinged to the door frame through blind hinges. The door leaf comprises an outer side panel, an inner side panel and a fireproof layer arranged between the outer side panel and the inner side panel. The fireproof door mirror is arranged on the door leaf. A fireproof lock between the door frame and the door leaf is used for unlocking or locking the door leaf. The upper end of the door leaf is connected with the door frame through a door closing device. The fireproof door further comprises an automatic warning system arranged on the door leaf. The door has the advantages of being good in fireproof property and safe, effectively preventing the door leaf from deforming, automatically giving an alarm, preventing burglary, and extinguishing fires.

Description

technical field [0001] The invention relates to a fireproof door, in particular to a steel heat-insulating fireproof door with a door mirror. 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, and the performance requirements are getting higher and higher. In these important places, the alert level requirements for fire protection are also 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, which will cause the door leaf to be easily deformed, thus failing to meet the fire protection performance requirements. Considering the needs of fire safety, traditional fire doors generally adopt a high-seal structure. Under the premise of satisfying fire protection, i...

Problems solved by technology

[0003] At present, the fire doors used in densely populated places, homes, and clubs have high thermal conductivity. When a fire breaks out, the temperature of the door leaf is likely to be too high, resulting in the door leaf being easily deformed, thus failing to meet the requirements of fire protection performance.

Considering the needs of fire safety, traditional fire doors generally adopt a high-seal structure. Under the premise of satisfying fire protection, it is difficult to take into account the function of observing the outdoor environment through perspective, which has no beneficial effect on family anti-theft and safety.

Moreover, when a fire occurs, traditional fire doors lack an automatic alarm function
