[0021] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0022] Example 1

[0023] See also Figure 1 to Figure 2 Embodiment 1 is described, including two door panels 2 installed on a door frame 1, both door panels 2 are provided with heat-insulating fireproof glass 8 on their front faces, both door panels 2 are provided with fireproof locks 3, fireproof expansion seals 6 and lifting seals 7 are respectively installed on the door panels 2, the fireproof expansion seals 6 and lifting seals 7 are respectively placed on two sides relatively far away, the lifting seals 7 are arranged on the fire-facing side, and the fireproof expansion seals 6 are arranged on the back-fire side, fireproof hinges 5 are installed between the door frame 1 and the door panels 2 on both sides, and three groups of fireproof hinges are symmetrically distributed on both sides. The door leaf 2 is hinged to the door frame 1 through a fireproof hinge 5. The door frame 1, the glass bead 9 and the frame 10 are all made of cold-rolled hot-dip galvanized steel plates. Two notches 14 are opened at the bottom of the door frame 1. The lifting seal strip 7 is in the notches 14. The door frame 1 is equipped with a starter head 15 on the notch 14. The automatic lifting seal strip 7 at the bottom of the door is installed inside the door frame 1, which belongs to the start key design. When closing the door, the collision head squeezes the door frame 1, and the lifting seal strip 7 descends; when opening the door, the collision head of the starter head 15 leaves the door frame 1, and the lifting seal strip 7 rises;

[0024] In the present embodiment, the fireproof door is provided to ensure that the door frame 1 and the door leaf 2 are tightly attached when closed, and the part in contact with the lifting sealing strip 7 is specially designed to be an arc, so as to achieve full contact with the lifting sealing strip 7 without affecting the tight fit between the door frame 1 and the door leaf 2, thereby meeting the design requirements of the clean room. When the fireproof expansion seal 6 and the lifting sealing strip 7 are provided, the lifting sealing strip 7 will catch fire first in the fire state, and will not affect the fireproof expansion seal 6. Under high temperature conditions, the fireproof expansion seal 6 will expand to block the gap between the door frame 1 and the door leaf 2, preventing smoke and fire from spreading to the back-to-fire side, thereby meeting the requirements of the fireproof door.

[0025] Example 2

[0026] See also Figure 2 to Figure 3 Example 2 is described. This embodiment further describes Example 1, including a glass bead 9 provided at the outer end of the heat-insulating fireproof glass 8, the glass bead 9 is sleeved around the heat-insulating fireproof glass 8, a frame 10 is installed on the glass bead 9, the frame 10 is wrapped with rock wool 4, a cover plate 11 is installed between the frames 10, the cover plate 11 is made of cold-rolled hot-dip galvanized steel plate, a fireproof latch 13 is installed between the door leaves 2, and a fireproof sequencer 12 is installed between one of the door leaves 2 and the door frame 1;

[0027] In this embodiment, correctly installing and maintaining the fireproof latch 13 can effectively increase the service life of the fireproof door, ensuring that it can play its due fireproof performance at critical moments, and the set fire sequencer 12 can prevent the spread of fire and isolate smoke.

[0028] In specific applications, the fire door provided in the device uses a lifting seal strip 7 for sealing and a fireproof expansion seal 6 for fireproofing, which are respectively placed on two relatively distant sides, the lifting seal strip 7 is arranged on the fire-facing side, and the fireproof expansion seal 6 is arranged on the back-fire side, and is compressed by the door frame 1 and the door panel when closed to play a separation role. In the case of fire, the lifting seal strip 7 catches fire first, and ensures that the smoke and fire are directed to the fire-inducing side, will not affect the fireproof expansion seal 6, and will not spread to the back-fire side. In the high temperature state, the fireproof expansion seal 6 expands to block the door frame 1 and the door leaf 2. The gap can prevent fireworks from running to the back-fire side, thereby meeting the requirements of fire doors. The fire doors are set to ensure that the door frame 1 and the door leaf 2 are tightly together when closed, and the part in contact with the lifting sealing strip 7 is specially designed to be an arc, so that it can be fully in contact with the lifting sealing strip 7 without affecting the close fit of the door frame 1 and the door leaf 2. The thickness of the door frame 1 and the door leaf 2 are both 50mm, which can be installed flush with the clean room wall panel to meet the design requirements of the clean room. A groove is designed on the door leaf 2 to cooperate with the lifting sealing strip 7, and a notch is designed on the door frame 1 to install the fire-proof expansion seal 6, thereby meeting the requirements of the clean door.
