[0038] The working principle of the above embodiment is:

[0039] (1) The first high temperature resistant layer 101 is silicon carbide fiber, which has a high temperature resistance effect. The first high temperature resistant layer 101 cooperates with the adjacent window frame 3 to make the window frame 3 have a certain fire resistance. The second high temperature resistant layer 105 is high purity aluminum silicate refractory fiber, which has thermal insulation, excellent shock resistance and thermal stability, and excellent machining performance, making construction more convenient and faster, and the maximum operating temperature can reach 1,260 degrees Celsius. The second high temperature resistant layer 105 cooperates with the adjacent window frame 3 to improve its fire resistance while being able to keep warm, thereby preventing the internal insulation material from being burned by high temperature. The insulating layer 102 is a fire-resistant heat-insulating ceramic coating. The fire-resistant heat-insulating ceramic coating is a waterproof, heat-insulating, moisture-proof, flame-retardant, wear-resistant, acid-resistant, alkali-resistant and odorless coating. The coating can withstand a temperature of up to 1,500 degrees Celsius. Celsius, the limit temperature is 2300 degrees Celsius. The insulation layer 102 is used to achieve heat preservation while improving the fire resistance. The strengthening layer 103 is pearl cotton, also known as polyethylene foam cotton, which has many advantages such as waterproof and moisture-proof, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, and strong impact resistance. The heat preservation capacity of the window frame 3 is enhanced by the strengthening layer 103, and the heat loss is further enhanced. The barrier layer 104 is polystyrene board, and the full name of polystyrene board is polystyrene foam board. It has excellent thermal insulation performance, high strength compression performance, excellent water resistance, moisture resistance, corrosion resistance, and durability. It is widely used in building insulation with high density, high strength, low expansion, flame retardant and other excellent properties. The barrier layer 104 improves the insulation capacity and increases the service life of internal insulation materials.

[0040] (2) When the damaged fireproof glass 2 needs to be replaced, the pull block 401 is pulled toward the side away from the window frame 3. When the pull block 401 moves, the limit block 402 slides inside and outside and compresses the reset spring 408. The movable rod 405 moves with the pull block 401 and gradually disengages from the positioning groove. When the reset spring 408 is compressed to the shortest, the movable rod 405 completely disengages from the positioning groove. At this time, the pull block 401 is rotated. The pull block 401 drives the slider 403 to rotate through the limit rod 407. At the same time, the movable rod 405 is moved by the movable rod 407 of the rectangular parallelepiped. The rod 405 drives the rotating block 406 to rotate, and the rotating block 406 drives the clamping block 404 to rotate together. After rotating ninety degrees, the clamping block 404 disengages from the clamping slot in the fireproof glass 2, and the fireproof glass 2 can be removed at this time. The disassembly mechanism 4 facilitates the staff to disassemble and replace the damaged fireproof glass 2 through the cooperation of the pulling block 401, the limiting block 402, the sliding block 403, the clamping block 404, the movable rod 405, the rotating block 406 and the limiting rod 407, so that the staff can quickly install the fireproof glass 2.
