The left window frame 1 and the outer side with the window frame are fixedly connected in an installation space reserved in advance in the wall. The window sashes 3 are arranged in the left window frame 1 and/or the right window frame 2, the window sashes 3 comprise a window sash frame 31 arranged in the left window frame 1 and/or the right window frame 2 and a glass layer 4 arranged in the window sash frame 31, namely, the window sash frame 31 in the application can be arranged in any one of the left window frame 1 and the right window frame 2, or the window sash frame 31 is arranged in the left window frame 1 and the right window frame 2, or the window sash frame 31 is not arranged in the window frame and the right window frame 2, and the specific implementation mode is based on the actual operation requirement of operators and is not limited.
With reference to fig. 1 and 2, it should be noted that when any one of the left and/or right frames 1, 2 is not filled with a window sash 3, it is desirable to choose to fill the glass layer 4 within the left and/or right frame 1, 2 of the unfilled window sash 3 and to also fill the glass layer 4 within the sash frame 31. Wherein, the fireproof ceramic cotton layers 5 are filled and arranged between the window frames of the left window frame 1 and/or the right window frame 2 and the glass layer 4 and between the sash frame 31 and the glass layer 4.
The fire-resistant ceramic wool arranged between the window frame and the glass layer 4 or between the fan frame 31 and the glass layer 4 can play a role in reducing air convection and improving heat insulation performance of the door and window on one hand, and on the other hand, when the door and window is in a fire scene range, the fire-resistant ceramic wool layer 5 is not easy to melt due to high temperature, so that safety in the actual use process of the door and window is improved.
Referring to fig. 2 and 3, the refractory ceramic wool layer 5 includes a first refractory ceramic wool strip 51 disposed above the top wall of the glass layer 4 and outside both side walls of the glass layer 4, and a second refractory ceramic wool strip 52 abutting the glass surface of the glass layer 4. Wherein a first refractory ceramic tampon 51 is disposed above the top wall of the glass layer 4 and outside the two glass rib walls vertically, thereby restricting the flow of air from above and from both the left and right sides of the glass layer 4. The second refractory ceramic cotton sliver 52 is abutted with the glass wool of the glass layer 4 and can form two square frame-shaped sealing rings connected end to end on the inner glass surface and the outer glass surface of the glass layer 4, so that the probability that air passes through the periphery of the glass layer 4 is further reduced, the probability of ventilation is reduced, and the heat preservation performance of doors and windows is further improved.
The arrangement of the first refractory ceramic tampons 51 and the second refractory ceramic tampons 52 may cooperate with each other to reduce the probability of air flowing along the side walls of the glass layer 4 and around the glass surface.

The glass layer 4 is provided with three layers of hollow glass 41, and a cavity 4 is arranged between every two layers of hollow glass 41. The thickness of each layer of the hollow glass 41 is not less than 5mm, and the thickness between each two layers of the hollow glass 41 is not less than 12mm. The glass closest to the indoor among the three layers of hollow glass 41 is set as fire-proof glass 43, and the two layers of glass closest to the outdoor among the three layers of glass is set as tempered glass.
The arrangement of the three glass layers 4 and the cavity 42 between the glass layers 4 can play a role in buffering heat transfer, so that the heat-insulating effect can be realized on one hand, and the flame-retardant effect can be realized on the other hand. Each of the hollow glass 41 should be set to a thickness of not less than 5mm at the time of setting, and a thickness between each two hollow glass 41 is not less than 12mm. The two layers of glass closest to the outside among the three layers of glass are set to be toughened glass, the possibility that the glass layers break due to external interference can be reduced, and the fire resistance of the glass layer 4 can be improved by setting the hollow glass 41 closest to the inside among the three layers of hollow glass 41 to be fireproof glass 43, so that the possibility that the fire-resistant heat-insulating door and window is damaged when being in a fire scene is reduced.
Referring to fig. 2 and 3, the inside of each of the left and right window frames 1 and 2 is filled with flame retardant polyurethane foam 7. The flame-retardant polyurethane foam 7 has various effects such as joint filling, bonding, sealing, heat insulation, sound absorption and the like after solidification, and the flame-retardant polyurethane foam 7 can also have flame-retardant effect, so that the fireproof effect of the fireproof heat-insulation door and window is further enhanced.
Referring to fig. 2 and 4, the inside of the left and right window frames 1 and 2 and the inside of the sash frame 31 are provided with fire-resistant expansion strips 8.
When the fire-resistant heat-insulating door and window is positioned near a fire scene, the fire-resistant expansion strips 8 near the fire heat source position expand to form local compact blocking gaps, so that the penetration and spreading of gas, smoke and flame when fire occurs at the resistance value are reduced, the probability of spreading the fire in the fire scene is reduced, and time is striven for rescue.
The implementation principle of the fire-resistant heat-insulation door and window is as follows: the fire-resistant ceramic wool arranged between the window frame and the glass layer 4 or between the fan frame 31 and the glass layer 4 can play a role in reducing air convection and improving heat insulation performance of the door and window on one hand, and on the other hand, when the door and window is in a fire scene range, the fire-resistant ceramic wool layer 5 is not easy to melt due to high temperature, so that safety in the actual use process of the door and window is improved. The arrangement of the three glass layers 4 and the cavity 42 between the glass layers 4 can play a role in buffering heat transfer, so that the heat-insulating effect can be realized on one hand, and the flame-retardant effect can be realized on the other hand. Each of the hollow glass 41 should be set to a thickness of not less than 5mm at the time of setting, and a thickness of not less than 12mm between every two layers of glass. The two layers of glass closest to the outside among the three layers of glass are set to be toughened glass, the probability that the glass layers break due to external interference can be reduced, and the glass closest to the inside among the three layers of glass is set to be fireproof glass 43, so that the fire resistance of the glass layers 4 can be improved, and the probability that the fire-resistant heat-insulating door and window is damaged when being in a fire scene is reduced.
