Description

Technical Field

[0001] The utility model relates to the technical field of fireproof doors, in particular to a steel fireproof door. Background Art

[0002] Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. They are usually used at the staircase entrances of buildings. Normally closed fire doors can effectively prevent the fire in the corridor from spreading to other floors in the event of a fire. Steel fire doors are a type of fire door. Steel fire doors are made of steel materials to make door frames, door leaf frames and door leaf panels. If the door leaf is filled with materials, they are filled with fireproof and heat-insulating materials that are non-toxic and harmless to the human body, and are equipped with fireproof hardware accessories to form doors with certain fire resistance.

[0003] When used, most existing steel fire doors only have the function of preventing the spread of fire. However, existing steel fire doors do not have a cooling function. When the steel fire doors are preventing the spread of fire, the flames will bake the steel fire doors for a long time, thereby increasing the temperature of the steel fire doors, which may cause the steel fire doors to deform, thereby greatly reducing the fireproof effect of the steel fire doors. Therefore, the utility model provides a steel fire door. Utility Model Content
