Steel fireproof entrance door

Abstract

The invention discloses a steel fireproof entrance door which comprises a door frame and a door leaf. The door frame is hinged to the door leaf through fireproof 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 further comprises an automatic warning device. The automatic warning device is arranged on the door leaf. The fireproof layer comprises a honeycomb flame-retardant paper layer and a fireproof filler layer, and the honeycomb flame-retardant paper layer is filled with the fireproof filler layer. The door leaf is opened or locked through a fireproof lock between the door frame and the door leaf. The door has the advantages of being good in fireproof performance, effectively avoiding deformation of the door leaf and having the functions of automatic warning, fire extinguishing and storage of fireproof articles.

Description

technical field [0001] The invention relates to a fireproof door, in particular to a steel entrance fireproof 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, and the performance requirements are getting higher and higher. In these important places, the level of fire protection alert is getting higher and higher. [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 fire resistance requirements. In addition, when a fire occurs, traditional fire doors lack an automatic alarm function. In addition, when a fire occurs, traditional fire doors lack automatic alarm and fire extinguishing functions. Moreove...

AI Technical Summary

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, which leads to the door leaf being easily deformed, thus failing to meet the requirements of fire protection performance.

In addition, when a fire breaks out, traditional fire doors lack an automatic alarm function

In addition, in the event of a fire, traditional fire doors lack automatic alarm and fire extinguishing functions

Moreover, the traditional fire door is a solid structure, and some fire protection supplies (such as fire gloves, fire masks, fire coats) cannot be saved.
