[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 fireproof partitions with a certain degree of fire resistance, installed between fire compartments, evacuation stairwells, vertical shafts, etc. In addition to the functions of ordinary doors, fire doors can also prevent the spread of fire and smoke, and can prevent the spread of fire within a certain period of time to ensure the evacuation of personnel.

[0003] At present, the existing traditional fire doors are generally assembled by welding. Although this traditional assembly method can assemble the fire doors stably, it also makes the fire doors have certain limitations. For example, after a fire, some parts of the fire doors may be damaged. The fire doors produced by traditional welding are difficult to repair, the maintenance cost is high, and it is not convenient for workers to operate. For this reason, we propose a plug-in non-welded fire door. Utility Model Content

Although this traditional assembly method can assemble the fire doors stably, it also makes the fire doors have certain limitations. For example, after a fire occurs, some parts of the fire doors may be damaged. The fire doors produced by traditional welding methods are difficult to repair, have high maintenance costs, and are not convenient for workers to operate.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a plug-in type non-welded fire door, comprising:
