[0002] Fireproof windows refer to windows made of steel window frames, steel window sashes, and fireproof glass that can isolate and prevent the spread of fire. The fire resistance limit of Class A fireproof windows is not less than 1.5 hours, which means that they can at least prevent the spread of fire for 1.5 hours, while that of Class B is not less than 1 hour, and that of Class C is not less than 0.5 hours. The window frame adopts a steel frame or a wooden frame with a certain strength to ensure the integrity and stability of the components. The steel frame and the pressure strip can be made of galvanized steel plate or stainless steel plate.

[0003] After searching, a steel explosion-proof and fireproof window with announcement number CN218439065U includes a main body and a bracket, window frames are arranged on both inner side walls of the bracket, fireproof glass is arranged between the inner side walls of the window frame, a fixing mechanism is arranged on the side wall of the window frame and located at the bottom corner, a sealing mechanism is arranged between the inner side walls of the bracket and located at one side of the window frame, the fixing mechanism includes a horizontal plate, sliding grooves are arranged on the side wall of the horizontal plate and close to the two sides, and a T-shaped push plate is slidably arranged between the inner side walls of the sliding groove; the steel explosion-proof and fireproof window allows users to quickly close the window frame between the brackets when a fire occurs, wherein the fireproof glass has good fireproof and explosion-proof functions, can prevent the fire from spreading, and can make the sealing strip fit tightly on the side wall of the window frame to block the gap between the window frame and the bracket, so as to prevent smoke from spreading to the interior of the room through the gap between the window frame and the bracket;

[0004] Based on the above patent, two groups of window frames are closed between the inner side walls of the bracket by hinges. During this process, the inclined groove at the bottom of the plug plate contacts the side wall of the bracket and is squeezed into the adjustment groove. When the horizontal plate moves to the position above the slot with the window frame, the spring applies thrust to the slide plate.

[0026] The mortise and tenon assembly includes two I-shaped tenons 17 located at both ends of the side panel 5, and a groove 1 is provided at both ends of the side panel 5. A groove 2 is provided at both ends of the top panel 16 and both ends of the bottom panel 2. One end of the I-shaped tenon 17 is interference-fitted inside the groove 1, and the other end of the I-shaped tenon 17 is interference-fitted inside the groove 2. Tenons 7 are provided at both ends of the top panel 16 and the bottom panel 2. The top tenon 7 passes through the top panel 16, the I-shaped tenon 17 and the side panel 5 from top to bottom in sequence, and the bottom tenon 7 passes through the bottom panel 2, the I-shaped tenon 17 and the side panel 5 in sequence from bottom to top. The filling assembly includes a heat preservation layer 12 located in front of the middle glass plate 8 and a fireproof layer 13 on the rear of the middle glass plate 8. The heat preservation layer 12 and the fireproof layer 13 are both located on the side close to the front and rear glass plates 8. Fireproof films 14 are provided on both inner and outer outer walls of the glass plates 8. Sealing rings 3 are provided around the outer walls of both sides of the glass plates 8. Explosion-proof bolts 1 are provided at both ends of the side plates 5. Fixed rods 6 are fixedly connected at both ends of the top plate 16. Fireproof curtains 9 are installed on the fixed rods 6.

When a fire occurs, the fusible rope 11 is melted due to the high temperature generated by the fire, and due to the gravity block 10, The fire curtain 9 will be pulled down as the gravity block 11 falls, so that the entire fire curtain 9 covers the entire window, and the high temperature resistance of the fireproof film 14 on both sides of the glass plate and the internal fireproof layer 13 can make the glass plate 18 more resistant to high temperature, so that the glass plate 18 is not easily damaged by high temperature. When an explosion occurs, the explosion-proof bolts 1 at both ends of the side panel 5 can release a part of the impact force generated by the explosion, reducing the damage to the window caused by the impact force. The thermal insulation layer 12 arranged inside the window can make the thermal insulation performance of the entire window better, thereby achieving the effect of improving the thermal insulation of the room. In normal times, the fire curtain 9 can be lowered or retracted by turning the hand 4 to roll up the fusible rope 11 to achieve the effect of shading.
