[0025] The door panels are provided with two groups, namely a first door panel 201 and a second door panel 301. The first door panel 201 is slidably connected to the inner wall of the first U-shaped frame 2, and the second door panel 301 is slidably connected to the inner wall of the second U-shaped frame 3. A locking mechanism 4 is detachably installed between the first door panel 201 and the second door panel 301, for changing the distance between the first door panel 201 and the second door panel 301 and the partition wall 1. When the first door panel 201 and the second door panel 301 are close to the partition wall 1, the door opening can be completely covered.

[0026] Normally, the first door panel 201 and the second door panel 301 are respectively located in the inner side walls of the first U-shaped frame 2 and the second U-shaped frame 3, and are in an open state, with the door opening exposed for people to pass through;

[0027] When a fire occurs, the first door panel 201 and the second door panel 301 are closed successively to completely cover the door opening, and then the first door panel 201 and the second door panel 301 are clamped and sealed by the locking mechanism 4 to block fire and smoke and prevent penetration through the chimney gap.
