[0002] Aluminum alloy doors and windows are windows with frames and sashes made of aluminum alloy building profiles, which are mainly divided into ordinary aluminum alloy doors and windows and broken bridge aluminum alloy doors and windows. Aluminum alloy windows have the characteristics of beauty, sealing, and high strength, and are widely used in the field of construction projects. Aluminum alloy is easy to extrude itself, the cross-sectional dimensions of the profiles are accurate, and the processing accuracy is high. Therefore, it is favored by many owners in decoration.
[0003] Aluminum alloy is a metal with very good thermal conductivity, and its thermal conductivity coefficient is 200 times that of steel, which makes the heat insulation performance of aluminum alloy windows poor. The indoor temperature is easily affected by the outside world, affecting the comfort of the occupants. Especially in the event of a fire, traditional aluminum alloy doors and windows do not have fireproof performance, and the window frames are easily damaged by high temperature, resulting in the doors and windows falling off, and it is easy to cause danger. Moreover, the sealing performance of aluminum alloy windows is not good, and gaps are likely to appear, resulting in the leakage of sound waves, making the occupants easily disturbed by external noises, affecting sleep quality and work efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0025] To make the above objects, features, and advantages of the present utility model more apparent and understandable, the following detailed description of the specific embodiments of the present utility model will be given in conjunction with the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0026] As Figure 1 shown, the fireproof and soundproof composite aluminum alloy doors and windows provided by the embodiment of the present utility model include a fixed window frame 1, a middle mullion 2, and an opening and closing window sash 3. Double-layer glass 4 is installed between the fixed window frame 1 and the middle mullion 2, as well as in the middle of the opening and closing window sash 3.
[0027] As Figure 1 and Figure 2 shown, cavities 5 are provided on the inner sides of the profiles of the fixed window frame 1, the middle mullion 2, and the opening and closing window sash 3 in the embodiment of the present utility model. A honeycomb-shaped soundproof layer 6 is filled in the cavities 5. A longitudinal storage box 7 is fixed at the left end position on the indoor side of the fixed window frame 1. A transverse fireproof curtain 9 is wound around a spring reel 8 inside the longitudinal storage box 7. The outer end of the transverse fireproof curtain 9 is connected to a fixed block 10 on the outer side of the longitudinal storage box 7. A positioning block 11 is fixed at the right end position on the indoor side of the fixed window frame 1. Mutually cooperating buckles 12 are respectively fixed on the opposite sides of the fixed block 10 and the positioning block 11.
[0028] Preferably, supporting plates 18 are integrally provided on the outdoor sides of the inner ends of the fixed window frame 1 and both ends of the middle mullion 2 in the embodiment of the present utility model. A limiting frame 19 is fixed on the indoor sides of the fixed window frame 1 and the middle mullion 2. The double-layer glass 4 is installed between the supporting plates 18 and the limiting frame 19. The double-layer glass 4 can be effectively installed and fixed by the supporting plates 18 and the limiting frame 19.
[0029] Preferably, first fixing grooves 20 are provided on the opposite sides of the supporting plates 18 and the limiting frame 19 facing the double-layer glass 4. A sealing rubber strip 21 is installed between the first fixing grooves 20 and the double-layer glass 4. A glass glue layer 22 is coated on the outer side of the sealing rubber strip 21. The sealing performance of the double-layer glass 4 is enhanced by the sealing rubber strip 21 and the glass glue layer 22, reducing the possibility of sound waves leaking through the gaps.
[0030] Preferably, second fixing grooves 23 are provided on the opposite sides of the fixed window frame 1 and the mullion 2 in the embodiments of the present utility model, opposite to the opening and closing window sash 3. Third fixing grooves 24 are respectively provided at both ends of the other side of the opening and closing window sash 3. Arc-shaped rubber strips 25 are respectively fixed in the second fixing grooves 23 and the third fixing grooves 24. When the opening and closing window sash 3 is closed, the arc-shaped rubber strips 25 enable it to fit closely, forming an effective sound insulation barrier.
[0031] Preferably, a plurality of arc-shaped plates 26 are provided on the side wall of the cavity 5 of the mullion 2 in the embodiments of the present utility model, and the plurality of arc-shaped plates 26 are arranged alternately on both sides of the cavity 5. The arc-shaped plates 26 can not only improve the overall structural strength, but also improve the firmness of the internal honeycomb-shaped sound insulation layer 6.
[0032] As Figure 1 and Figure 4 As shown, a horizontal storage box 13 is fixed at the upper end position on the indoor side of the fixed window frame 1 in the embodiments of the present utility model. A longitudinal fireproof curtain 14 is wound around the inner side of the horizontal storage box 13 through a rotating shaft. The outer end of the longitudinal fireproof curtain 14 is connected to a counterweight strip 15 below the horizontal storage box 13. A rotating disk 16 is fixed at the outer end of the rotating shaft, and a rotating pull rope 17 is installed on the outer edge of the rotating disk 16.
[0033] Preferably, a high-temperature resistant cushion block 27 is provided at the lower end of the double-layer glass 4. The high-temperature resistant cushion block 27 can stably support the lower end of the double-layer glass 4, prevent the glass from falling off due to heat, increase the high-temperature resistance of the window, and further improve the fireproof ability.
[0034] The working principle of the present utility model is as follows: In the present utility model, the cavities 5 in the fixed window frame 1, the mullion 2, and the opening and closing window sash 3 are filled with a honeycomb sound insulation layer 6. This structure can further reduce the propagation of sound waves because the sound waves will undergo multiple reflections and refractions when passing through the honeycomb structure, thereby consuming their energy. The structure of the double-glazed glass itself can effectively isolate the propagation of sound waves and reduce the interference of external noise. The air layer forms a sound barrier between the two layers of glass, increasing the resistance to sound wave transmission. The sealing rubber strips 21 and the glass glue layer 22 between the supporting plate 18 and the limiting frame 19 and the double-glazed glass 4 enhance the sealing performance of the window and reduce the possibility of sound waves leaking through the gaps. At the contact points of the fixed window frame 1, the mullion 2 and the opening and closing window sash 3, as well as at both ends of the opening and closing window sash 3, arc-shaped rubber strips 25 are installed, which can fit tightly when the opening and closing window sash 3 is closed, forming an effective sound insulation barrier. When a fire occurs, the horizontal fire curtain 9 can be unfolded from the longitudinal storage box 7 and fixed by the buckles 12 on the fixing block 10 and the positioning block 11, thereby forming a fire barrier on the indoor side of the window frame and effectively preventing the spread of flames and high-temperature air currents. Similarly, the longitudinal fire curtain 14 is unfolded from the horizontal storage box 13 and maintained in a vertical state by the weight strip 15. The user can conveniently operate the lifting of the longitudinal fire curtain by rotating the pull rope 17 and the rotating disc 16, which can form a double fire barrier, enhance the fire prevention ability of the doors and windows, and improve the overall quality and use value of the doors and windows.
