The sealing strip 17 blocks the gap between the door frame 1 and the door leaf 3 to prevent smoke from entering. There is a gap between the fireproof board 4 and the sound insulation board 16, and the two are connected by a connecting column. The fireproof board 4 and the heat insulation board are connected by a connecting column to leave a gap. The heat insulation and sound insulation prevent people from being scalded due to the high temperature of the fire, and reduce the overall weight of the door leaf 3 to facilitate people to push and pull.

[0027] When in use, when a fire occurs, the crowd retreats behind the door leaf 3 and closes the left and right door leaves 3, the sealing flame retardant strip 33 blocks the gap between the left door leaf 31 and the right door leaf 32, and the fireproof sealing door block 6 cooperates with the slide groove 11 and the groove 9 when closing the door, and the compression spring 10 retracts the fireproof sealing door block 6 into the groove 9. When the spring 10 contracts, there is a downward pressure on the fireproof sealing door block 6. Since the fireproof sealing door block 6 is made of fireproof rubber material, the door gap on the lower side of the door leaf 3 is blocked. At the same time, the sealing strip 17 blocks the gap between the door frame 1 and the door leaf 3 to prevent smoke from entering and spreading, protecting the personal safety of the crowd. The thick smoke generated by the fire is detected by the smoke alarm 14, and the smoke alarm 14 sends a signal to the property management monitoring system, so that the property personnel can discover the fire in the first time and take corresponding protective measures to ensure the life safety of the personnel.
