[0046] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation and protection scope of the present invention.

[0047] The present invention also has the following implementation methods based on the above:

[0048] In a further embodiment of the present invention, the material of the glass fiber reinforced polyurethane frame profile 71 and the glass fiber reinforced polyurethane fan profile 72 is glass fiber reinforced polyurethane profile. Compared with traditional composite materials, the glass fiber reinforced polyurethane composite profile has the advantages of higher strength, high modulus, high impact strength, high oxygen index, high thermal insulation and low expansion coefficient.

[0049] In a further embodiment of the present invention, the glass fiber reinforced polyurethane material itself has a low thermal conductivity coefficient, and is not prone to generating gaps when the ambient temperature changes significantly (gaps will reduce air tightness and cause convective heat transfer), and does not require reinforced steel, so the windows it forms have obvious advantages in thermal insulation performance.

[0050] In a further embodiment of the present invention, the thermal conductivity of the glass fiber reinforced polyurethane profile is 1 / 1300 of that of aluminum alloy, and the thermal conductivity is only 0.34 W / m·K.

[0051] In further embodiments of this invention, the high strength and high modulus of the fiberglass-reinforced polyurethane material provide the finished window with excellent wind pressure resistance. Whether casement or sliding, with or without aluminum alloy facings, series 65 and above can reach 5000Pa (Class 9). Precisely because of these mechanical advantages, fiberglass-reinforced polyurethane profiles can be used to construct large windows with wide openings and can be used to create casement doors. The airtightness of casement windows can reach Class 8, as per the national standard.

[0052] In further embodiments of this invention, the glass fiber reinforced polyurethane material has a heat deformation temperature of approximately 240°C, demonstrating excellent high-temperature resistance and even superior low-temperature resistance, preventing it from becoming brittle when exposed to cold. Glass fiber reinforced polyurethane exhibits strong corrosion resistance against most acids, alkalis, salts, organic matter, seawater, and humid air. Furthermore, it is rustproof and corrosion-resistant, surpassing other materials for door and window profiles. Therefore, glass fiber reinforced polyurethane doors and windows offer durability advantages in both extremely cold and humid regions.

[0053] In a further embodiment of the present invention, the outdoor side of the glass fiber reinforced polyurethane frame profile 71 and the frame outer aluminum 61 are connected by multiple frame outer clips 91, the indoor side of the glass fiber reinforced polyurethane frame profile 71 and the frame inner aluminum 62 are connected by multiple frame inner clips 92, and the indoor side of the glass fiber reinforced polyurethane fan profile 72 and the fan inner aluminum 64 are connected by multiple frame inner clips 92. Since the thermal expansion coefficients of the aluminum alloy profile and the glass fiber reinforced polyurethane profile are different, direct connection between the aluminum alloy profile and the glass fiber reinforced polyurethane profile is avoided, and the strength is destroyed due to expansion under high temperature conditions, thereby extending the time that the window remains intact in high temperature environment and flame burning state.

[0054] In a further embodiment of the present invention, a frame fireproof hook plate 52 is installed in the second installation hole, and a fan fireproof hook plate 51 is installed in the glass fiber reinforced polyurethane fan profile 72. The frame glass 82 is supported and limited by the frame fireproof hook plate 52, and the fan glass 81 is supported and limited by the fan fireproof hook plate 51, thereby enhancing the supporting strength of the glass fiber reinforced polyurethane frame profile 71 for the frame glass 82 and the supporting strength of the glass fiber reinforced polyurethane fan profile 72 for the fan glass 81, thereby extending the time that the window remains intact in a high temperature environment and a flame burning state.

[0055] In a further embodiment of the present invention, the inner sides of the fan fireproof hook plate 51 and the frame fireproof hook plate 52 are filled with graphite-based fireproof expansion cotton strips, and the first graphite-based fireproof expansion cotton strips 21 are bonded in the first installation hole. The graphite-based fireproof expansion strip is a high-performance fireproof expansion material prepared based on expandable graphite. When encountering fire, the material will rapidly expand to 15-50 times its original volume to fully seal the surrounding gaps and holes, thereby forming an effective fire and smoke barrier.

[0056] In a further embodiment of the present invention, a first fireproofing strip 31 is installed between the indoor side of the sash glass 81 and the inner aluminum 64 of the sash, and a second fireproofing strip 32 is installed between the outdoor side of the frame glass 82 and the inner baffle of the frame. The fireproofing strips are made of ceramic fiber fireproof material. They have high-temperature resistance, good thermal stability, and low thermal conductivity. They are used as fireproofing materials in various fireproof glass inlays. At high temperatures, they buffer the stress caused by deformation of the glass and profiles, preventing the fireproof glass from bursting.

[0057] In a further embodiment of the present invention, the sash glass 81 and the frame glass 82 are both three-layer or more insulating glass, and the single pieces of fireproof glass are bonded together by fireproof adhesive.

[0058] In a further embodiment of the present invention, the indoor side of the frame glass 82 and the decorative aluminum 66 inside the frame are sealed and bonded by fireproof glue 1; the outdoor side of the sash glass 81 and the sash outer aluminum 63 are sealed and bonded by fireproof glue 1, the indoor side of the sash glass 81 and the inner edge of the sash inner aluminum 64 are sealed and bonded by fireproof glue 1, and the indoor outer edge of the sash glass 81 and the inner periphery of the glass fiber reinforced polyurethane sash profile 72 are sealed and bonded by fireproof glue 1. The fireproof glue 1 plays a fireproof and sealing role, thereby extending the time that the window remains intact in a high temperature environment and under flame burning conditions.

[0059] In a further embodiment of the present invention, when the window sash is in a closed state, the outdoor outer periphery of the glass fiber reinforced polyurethane sash profile 72 abuts against the main fireproof strip 41, the outdoor fireproof strip 42 abuts against the aluminum 63 outside the sash, and the indoor fireproof strip 43 abuts against the indoor side of the aluminum 62 inside the frame. The main fireproof strip 41, the outdoor fireproof strip 42 and the indoor fireproof strip 43 are used to seal the window sash and the window frame, thereby improving the sealing and fireproofing performance between the window sash and the window frame.

[0060] In a further embodiment of the present invention, an inner-frame glass fireproof strip 44 is provided between the frame glass 82 and the inner-frame press-fitted aluminum 65, and an outer-frame glass fireproof strip 45 is installed on the inner edge of the outer-frame aluminum 61 located at the first installation opening. The outer-frame glass fireproof strip 45 is against the outdoor side of the frame glass 82, and the frame glass 82 in the second installation opening is fire-sealed by the inner-frame glass fireproof strip 44 and the outer-frame glass fireproof strip 45, thereby improving the sealing and fireproof performance of the window frame.

[0061] In a further embodiment of the present invention, the fan fireproof hook plate 51 is used to support and limit the fan glass 81, and the frame fireproof hook plate 52 is used to support and limit the frame glass 82. The inner sides of the fan fireproof hook plate 51 and the frame fireproof hook plate 52 are filled with graphite-based fireproof expansion cotton strips. During the fire resistance test, the furnace reaches a higher temperature, the pressure strips soften and fall off, causing the glass to fall off, and the supporting strength of the fan fireproof hook plate 51 and the frame fireproof hook plate 52 for the fireproof glass decreases. At the same time, the graphite-based fireproof expansion strips will expand rapidly and seal the surrounding gaps and holes in all directions to support the fireproof glass and prevent the glass from falling off. The fireproof cotton strips buffer the stress caused by the deformation of the glass and the profile, prevent the fireproof glass from bursting, and extend the time that the window remains intact in a high temperature environment and under flame burning conditions.

[0062] In a further embodiment of the present invention, the fireproof properties of the glass fiber reinforced polyurethane profile are utilized, and aluminum alloy profiles with fire retardant effects are installed indoors and outside thereof. At the same time, graphite-based fireproof expansion cotton strips and fireproof rubber strips are used to improve the fireproof performance and sealing performance of the entire window. Installing fireproof hook plates on the periphery of the fireproof hollow glass can effectively strengthen the supporting strength of the glass fiber reinforced polyurethane profile for the fireproof hollow glass. At the same time, filling the fireproof hook plates with graphite-based fireproof expansion cotton strips can effectively strengthen the supporting strength and sealing performance of the fireproof hook plates for the fireproof hollow glass in a high temperature environment. At the same time, the stress generated by the deformation of the fireproof hollow glass and the aluminum alloy profile is buffered by the fireproof cotton strips to prevent the fireproof hollow glass from bursting.

[0063] In a further embodiment of the present invention, the aluminum-clad glass fiber reinforced polyurethane fire-resistant window effectively combines several fire-resistant materials and fire-resistant insulating glass, achieving the 0.5-hour fire resistance integrity requirement with limited increase in material cost.

[0064] In a further embodiment of the present invention, the fireproof strips, graphite-based fireproof expansion cotton strips, fireproof hook plates, fireproof cotton strips and fireproof hollow glass cooperate with each other to enhance the supporting strength of the window body to the fireproof hollow glass. At the same time, the fire resistance integrity of the entire window is enhanced without increasing the thickness of the window body.
