BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a schematic diagram of the structure of the present invention. DETAILED DESCRIPTION
[0011] like Figure 1As shown, a high-performance plastic steel fire-resistant window includes a casement frame profile 1, a window frame 2, a casement middle support profile 3, an opening window 4, a fixed window 5, a casement sash profile 6, and a casement window sash 7. The casement frame profile 1 is provided with a casement frame profile independent drainage cavity 16, a casement frame profile insulation cavity A18, a casement frame profile steel lining cavity 17, and a casement frame profile insulation cavity B19 and C20 cavity structures from the outdoor side to the indoor side. The casement frame profile internal cavities D27 and E29 of the casement frame profile 1 are provided with stainless steel sheets 26 and 28 with a thickness of 1.2-1.5 mm, respectively, so that the strength of the entire plastic steel profile is increased, thereby increasing the fire resistance. The casement frame profile 1 has fire expansion strips 39 and 40 in the internal slots F34 and G35, respectively; when the temperature of the entire window rises, the fire expansion strips expand 10-20 times in volume, filling the gaps in the window, and the entire window has fire resistance, which can achieve fire resistance integrity for 1 hour. The casement frame profile 1 with stainless steel sheets 26 and 28 installed is welded to form a fire-resistant window frame 2, and the casement muntin profile 3 has stainless steel sheets 26 and 28 with a thickness of 1.2-1.5mm in the internal chambers X30 and Y31, respectively, to increase the strength of the entire plastic steel profile, thereby increasing the fire resistance. The casement middle brace profile 3 has fire expansion strips 39 and 40 in the internal slots M37 and N38 respectively; when the temperature of the whole window rises, the fire expansion strips expand 10-20 times, so that the gaps in the window are filled, and the whole window has fire resistance, which can achieve fire resistance integrity for 1 hour. The casement middle stile profile 3 installed with stainless steel sheets 26 and 28 is welded to the window frame 2, and the window frame 2 is divided into an opening window 4 and a fixed window 5. The casement frame profile 1 and the casement middle stile profile 3 of the fixed window 5 are installed with hollow glass 13 through the glass strip 10; the casement window sash 7 formed by welding the casement sash profile 6 in the opening window 4, and the casement sash profile 6 is provided with a casement sash profile independent drainage chamber 21, a casement sash profile insulation chamber Q23, a casement sash profile steel lining chamber 22, and a casement sash profile insulation chamber R24 chamber structure from the outdoor side to the indoor side. The casement sash profile 6 has internal chambers J32 and K33 respectively provided with stainless steel sheets 26 and 28 with a thickness of 1.2-1.5 mm. This increases the strength of the entire plastic steel profile, thereby increasing the fire resistance. The casement sash profile 6 has internal card slots 36 provided with fire expansion strips 39. When the temperature of the entire window rises in the fire, the fire expansion strips expand 10-20 times in volume, filling the gaps in the window, and the entire window has fire resistance, which can achieve fire resistance integrity for 1 hour. The casement sash profile 6 has a hardware European-style slot 25, and the hardware European-style slot 25 has hardware 12, so that the entire window can be locked.The casement sash profile 6 on the casement window sash 7 is installed with fireproof hollow glass 11 through glass bead 10, and the casement window sash 7 is provided with a transmission and handle hardware 12 to realize the locking of the open window 4. The large rubber strip 9 is inserted into the rubber strip notch 8 of the casement frame profile 1 and the casement middle stile profile 3 of the open window 4, and an independent watertight chamber 14 and airtight chamber 15 are formed between the casement frame profile 1 and the casement middle stile profile 3 and the casement window sash 7, which greatly improves the sealing performance and thermal insulation performance of the whole window, and finally forms this high-performance plastic steel fire-resistant window. Since the window profile is completely penetrated with stainless steel sheets 26 and 28 to form a fireproof surface, the plastic profile softens after the window encounters fire, but the internal stainless steel remains resistant to high temperatures, so the whole window can be fire-resistant for 1 hour.
