Description

Technical Field

[0001] The utility model relates to the technical field of fireproof doors, in particular to a fireproof door with strong safety protection performance. Background Art

[0002] A fire door refers to a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It is a fire-resistant partition with a certain fire resistance installed in fire compartments, evacuation stairwells, vertical shafts, etc. It is specifically used to isolate fire sources in residential buildings and plays a huge role in fire fighting. Once a fire occurs, people can get a chance to escape through the fire door.

[0003] A fire door with strong safety protection performance is disclosed with the publication number CN218177083U after retrieval, comprising a fire door body, an outer wall surface of the fire door body is provided with a door frame, one side of the door frame is fixedly installed with a plurality of hinges, and the fire door body is connected to the door frame through the hinges; a fire prevention component is arranged on the top surface of the fire door body, and is used to fireproof the fire door body, the fire prevention component comprises two water collection tanks, and the two water collection tanks are both opened on the top surface of the fire door body, and the fire door body, the water collection tank, the connecting hole, the mounting plate, the water outlet hole and the melting plate are arranged to cooperate with each other, so as to facilitate the improvement of the safety protection and fire prevention performance of the fire door body, and at the same time, the water in the water collection tank flows out through the water outlet hole, and can soak the position close to the fire door body, so as to suppress the fire close to the fire door body for a short time, and facilitate the possibility of personnel escaping through the fire door body.

[0004] In response to the above-mentioned related technologies, the inventor believes that the existing fire doors with strong safety protection performance only soak the position close to the fire door when in use, which can only suppress the fire for a short time and cannot enhance the protection performance of the fire door. When the water in the sump flows out, the fire will burn the inside of the door panel through the water outlet, thereby reducing the fire resistance of the fire door. Therefore, we propose a fire door with strong safety protection performance. Utility Model Content
