fireproof door

Abstract

The invention relates to the technical field of anti-theft doors, in particular to a fireproof anti-theft door. The fireproof anti-theft door comprises a door body, and the door body comprises two door plates and a grating layer clamped between the two door plates; and the grating layer comprises a plurality of gratings, the gratings and the two door plates form accommodating spaces, and the accommodating spaces are filled with ceramic green bodies to be subjected to sinter forming. According to the fireproof anti-theft door, by adopting the ceramic green bodies to be subjected to the sinter forming as filling materials, when a fire occurs, the ceramic green bodies can be subjected to the sinter forming to form ceramics through heat of the fire; and in the process of heating the ceramic green bodies, the ceramic green bodies can absorb certain heat due to the fact that the ceramic green bodies contain water, so that part of heat of the fire is absorbed by the ceramic green bodies so asto reduce the spreading speed of the fire behavior, meanwhile, part of formed ceramics can further prevent or retard the spreading of the fire behavior due to low thermal conductivity, and the speedof heat transmission is reduced.

Description

technical field [0001] The invention relates to the technical field of anti-theft doors, in particular to a fire-proof and anti-theft door. Background technique [0002] At present, the country has two main requirements for the entrance door. On the one hand, the "Code for Residential Design" clearly requires that the entrance door should use anti-theft safety door. On the other hand, from the perspective of fire protection, the entrance door must have fire protection function. [0003] In order to meet the functions of fire prevention and anti-theft at the same time, the existing entrance doors usually adopt the structure of steel door frame and door panel. The steel door frame door panel can prevent the fire source from expanding in time when a fire occurs, and also has sufficient anti-destructive ability. However, if the structure of the steel door frame and door panel is directly exposed to the outside, and the thermal conductivity of the steel door frame and door panel ...

AI Technical Summary

Problems solved by technology

However, if the structure of the steel door frame and door panel is directly exposed to the outside, and the thermal conductivity of the steel door frame and door panel is good, the temperature of the entire security door will be extremely high in the event of a fire. If you accidentally touch it by mistake, it will cause burns; After burning, it will produce severe expansion deformation and lock with the door frame. For firefighters, it is very difficult to open, which seriously affects the rescue.
