Description

Technical Field

[0001] The utility model relates to the technical field of fireproof doors, in particular to a fireproof door which is convenient to disassemble and replace. Background Art

[0002] A fire door is a door used to prevent the spread of fire. It has flame retardant, fire-resistant, heat-insulating, and sealing functions, and can effectively isolate the spread of flames, smoke, and heat, playing a role in fire prevention and escape. Fire doors are usually made of fireproof materials, such as steel plates, steel frames, fire-resistant glass, fire-resistant seals, etc. Their structure and materials can withstand high temperatures and have a certain fire resistance time. According to the length of the fire resistance time, fire doors can be divided into different levels, such as 30 minutes, 60 minutes, 90 minutes, etc. Fire doors are generally installed at the entrances and exits of fire partitions such as passages, stairwells, and elevator halls in buildings, as well as places that require special fire protection requirements, such as chemical laboratories and machine rooms. As the use of fire doors goes on, their surfaces may be bumped, and they need to be disassembled and replaced.

[0003] However, when replacing some existing fire doors, since most of them are arranged as a whole, when they are replaced, usually the entire door is replaced, rather than the damaged part of the fire door, which will increase some unnecessary economic losses. Moreover, when the fire door is replaced later, since the building has been completed, it is not convenient to replace the entire fire door in the building. Therefore, it is necessary to solve this problem. Utility Model Content
