[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-4 This utility model discloses a composite non-insulated fireproof glass window, including a window frame structure 1. The window frame structure 1 has two window frame openings 2 inside. The left window frame opening 2 is provided with a movable frame structure 4. The movable frame structure 4 is provided with a locking handle 5 on the outside. The right window frame opening 2 is provided with a fixed frame structure 6. The movable frame structure 4 and the fixed frame structure 6 are both provided with a composite glass structure 7 inside.
[0027] The movable frame structure 4 and the fixed frame structure 6 have the same structure. The movable frame structure 4 includes a protective profile 401, and an installation cavity 408 is provided on the inner side of the protective profile 401.
[0028] The composite glass structure 7 includes an inner glass layer 701, a middle glass layer 702, and an outer glass layer 703. A sound insulation layer 704 is provided between the inner glass layer 701 and the middle glass layer 702. A fireproof layer 705 is provided between the middle glass layer 702 and the outer glass layer 703. A reinforcing layer 706 is provided at the bottom of both the sound insulation layer 704 and the fireproof layer 705. An embedded strip 707 is provided below the reinforcing layer 706.
[0029] Specifically, a movable hinge 3 is movably connected to the outer side of the window frame opening 2, and the other side of the movable hinge 3 is connected to the outer wall of the movable frame structure 4.
[0030] In this embodiment, the design of the movable hinge 3 allows the movable frame structure 4 to rotate flexibly within the window frame opening 2, facilitating the user to open or close the window. Furthermore, the movable hinge 3 is made of high-strength materials, ensuring its stability and durability during prolonged use.
[0031] Specifically, a cover plate 402 is fixedly connected to the outer side of the protective profile 401. A splicing notch 403 is provided at the junction of the cover plate 402 and the protective profile 401. The splicing notch 403 overlaps with the window frame opening 2.
[0032] In this embodiment, the design of the cover plate 402 further enhances the stability and sealing between the movable frame structure 4 and the window frame structure 1. The splicing notch 403 allows the cover plate 402 to precisely overlap with the window frame opening 2, thereby avoiding gap problems caused by improper installation. This design not only improves the overall aesthetics of the window but also ensures that the window's sealing and thermal insulation performance are not affected during use.
[0033] Specifically, a sealing strip 404 is provided on the inner side of the cover plate 402, and the sealing strip 404 is a polytetrafluoroethylene strip.
[0034] In this implementation scheme, the design of the 404 sealing strip further enhances the window's sealing performance. As a high-quality sealing material, PTFE strips possess excellent chemical corrosion resistance and high-temperature resistance, effectively preventing external factors such as air, dust, and moisture from entering the room through gaps, thus ensuring the window's thermal insulation and soundproofing effects. Simultaneously, PTFE strips also exhibit good elasticity and wear resistance, maintaining their shape and functional stability during prolonged use, further improving the window's durability and practicality.
[0035] Specifically, the opening of the protective profile 401 is provided with a connector strip 405, and a waterproof strip 406 is movably inserted into the inner side of the connector strip 405.
[0036] In this embodiment, the design of the waterproof strip 406 further enhances the window's waterproof performance. At the interface between the movable frame structure 4 and the window frame structure 1, the waterproof strip 406 effectively prevents rainwater infiltration, keeping the indoor environment dry. The insertion strip 405 ensures that the waterproof strip 406 can be securely installed at the opening of the protective profile 401, preventing loosening or detachment due to long-term use or external factors. This design not only improves the window's waterproof performance but also ensures the window's stability and durability under harsh weather conditions. Furthermore, the waterproof strip 406 is made of high-quality waterproof material, possessing excellent elasticity and weather resistance, maintaining its waterproof effect during prolonged use and further extending the window's service life.
[0037] Specifically, the inner glass layer 701, the sound insulation layer 704, the middle glass layer 702, the fireproof layer 705, and the outer glass layer 703 are arranged in order from the inside to the outside, and the inner glass layer 701, the sound insulation layer 704, the middle glass layer 702, the fireproof layer 705, and the outer glass layer 703 are bonded together with adhesive.
[0038] In this embodiment, the arrangement of the inner glass layer 701, the sound insulation layer 704, the middle glass layer 702, the fire-resistant layer 705, and the outer glass layer 703, along with the use of adhesives, ensures the overall strength and stability of the composite glass structure 7. The choice of adhesive is crucial for ensuring a tight bond and long-term durability between the layers.
[0039] The adhesive possesses excellent temperature resistance and chemical stability, maintaining its bonding strength even in extreme environments, thus effectively preventing separation or detachment between layers. This design not only enhances the overall strength of the window but also ensures its safety and reliability during use.
[0040] Specifically, the sound insulation layer 704 is a gas-filled layer, and the fireproof layer 705 is a fireproof isolation membrane layer.
[0041] In this embodiment, the sound insulation layer 704, as a gas-filled layer, can effectively block the transmission of sound and improve the sound insulation effect of the window. The gas-filled layer usually uses an inert gas, such as argon or krypton. These gases have low thermal conductivity and good sound insulation performance, which can effectively reduce the interference of external noise while maintaining the good thermal insulation performance of the window, providing users with a quieter and more comfortable indoor environment.
[0042] The 705 fire-resistant layer, acting as a fire-resistant isolation membrane, can rapidly expand to form a protective film in the event of a fire, effectively preventing the spread of fire and smoke, thus buying precious time for escape and rescue. This fire-resistant isolation membrane is typically made of special fire-resistant materials, possessing excellent fire resistance and chemical stability. It maintains its structural and functional integrity even at high temperatures, thereby ensuring the window's fire resistance in a fire.
[0043] Specifically, the reinforcing layer 706 is a fiber calcium silicate board, and the inner strip 707 is a porous rock wool material.
[0044] In this embodiment, fiber calcium silicate board, as a high-performance building material, possesses excellent high-temperature resistance, corrosion resistance, and mechanical strength. Using it as a reinforcing layer 706 can effectively enhance the load-bearing capacity of the composite glass structure 7, improving the overall strength and stability of the window. Simultaneously, fiber calcium silicate board also exhibits good sound and heat insulation properties, which can reduce heat transfer to a certain extent and improve the window's thermal insulation effect.
[0045] The 707 embedded strip is made of porous rock wool, a high-quality thermal insulation material with excellent fire resistance and insulation properties. Using it as an embedded strip not only further improves the window's insulation effect but also effectively prevents the spread of fire in the event of a fire, providing greater safety for escape and rescue. Furthermore, porous rock wool also has good sound absorption properties, which can reduce external noise interference to a certain extent and improve indoor comfort.
[0046] Specifically, a sealing gasket 407 is provided at the connection between the opening of the mounting cavity 408 and the composite glass structure 7.
[0047] In this embodiment, the design of the sealing gasket 407 further enhances the sealing performance between the movable frame structure 4 and the composite glass structure 7. The sealing gasket 407 is typically made of highly elastic and aging-resistant materials, which can maintain the stability of its shape and function during long-term use, thereby effectively preventing external factors such as air, dust, and moisture from entering the room through gaps, further improving the heat insulation and sound insulation effect of the window.
[0048] Meanwhile, the sealing gasket 407 can also absorb and cushion the impact force generated during the opening and closing of the window to a certain extent, extending the window's service life. This design not only improves the practicality and durability of the window, but also provides users with a quieter, more comfortable, and safer indoor environment.
[0049] In summary, this composite non-insulated fireproof glass window, by setting up a movable frame structure 4 and using cover plates 402 and sealing strips 404, can effectively achieve a tight seal between the protective profile 401 and the window frame opening 2. When closed, these cover plates 402 and sealing strips 404 ensure that there are no gaps between them, thus achieving a good sealing effect. Furthermore, with the design of the movable hinge 3, the movable frame structure 4 can be flexibly connected to the window frame opening 2. This design not only allows users to easily open and close the window during use but also improves the convenience and flexibility of use. Users can easily adjust the position of the movable frame structure 4 according to their needs, thereby meeting different usage scenarios and requirements. This design not only enhances the user experience but also ensures the efficiency and reliability of the protective profile 401 during use.
[0050] By incorporating a composite glass structure 7, a sound-insulating layer 704 and a fire-resistant layer 705 are respectively installed between the inner glass layer 701, the middle glass layer 702, and the outer glass layer 703. These special layers are designed to provide additional protective barriers. Furthermore, a reinforcing layer 706 is installed at the bottom of both the sound-insulating layer 704 and the fire-resistant layer 705. This not only provides excellent fire resistance but also effectively enhances the load-bearing capacity of the glass structure, as well as good thermal insulation performance. It effectively reduces heat transfer, improves the window's insulation effect, and enhances the overall strength and stability of the window. This design not only meets users' safety requirements but also improves the practicality and durability of the window.
