Description

Technical Field

[0001] This utility model relates to the field of fire-resistant doors and windows, and more specifically, it relates to an aluminum alloy fire-resistant window. Background Technology

[0002] With the continuous improvement of building fire protection standards, aluminum alloy fire-resistant windows are gradually replacing traditional steel fire-resistant windows as the mainstream choice due to their advantages such as lightweight, ease of processing, and good appearance. However, existing aluminum alloy fire-resistant windows still have the following technical challenges in practical applications: Insufficient fire resistance: Most products use ordinary aluminum alloy profiles, which have rapid strength decay at high temperatures (above 300℃) (with a retention rate of only 40%-50%), making them prone to deformation and collapse; at the same time, ordinary sealing strips (such as EPDM rubber strips) have poor temperature resistance (≤150℃), and are prone to softening and failure in a fire, causing flames and smoke to penetrate from the gaps.

[0003] Structural connections are prone to detachment: The window sash and window frame are connected by ordinary hinges. Under high temperature, the metal parts of the hinges are prone to softening, or the window sash may deform due to heat, which may cause the window sash to detach and the glass to fall, thus compromising the fire resistance integrity.

[0004] Insufficient insulation and support: Aluminum alloy profiles have a high thermal conductivity, and ordinary single-cavity structures cannot effectively block heat transfer; fireproof glass is mostly single-layer fireproof glass with poor insulation, which can easily lead to a rapid increase in temperature on the inside of the window and ignite combustibles inside.

[0005] To address the aforementioned issues, there is an urgent need to design an aluminum alloy fire-resistant window with excellent fire resistance, a robust structure, and good thermal insulation and sealing, in order to meet the higher requirements for building fire safety. Utility Model Content

[0006] The purpose of this invention is to provide an aluminum alloy fire-resistant window that has strong fire resistance integrity, a stable and secure structure, and excellent sealing and heat insulation.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an aluminum alloy fire-resistant window, comprising a fixed window frame and a movable window sash; Both the fixed window frame and the movable window sash have high-performance aluminum alloy frames; the movable window sash includes an outer frame and fireproof glass set inside the frame. The fixed window frame has a raised support platform on one side of its inner side. The support platform is used to support the outer side of the movable window sash frame. The support platform is equipped with a high-temperature resistant sealing strip. The fixed window frame and the frame are connected by a fireproof hinge on one side, and a fireproof lock is provided between the other side of the fixed window frame and the other side of the frame.

[0008] As a preferred embodiment of this utility model, an electric fireproof window closer is connected between the top edge of the fixed window frame and the top edge of the side frame.

[0009] As a preferred technical solution of this utility model, the inner and outer sides of the fixed window frame are equipped with smoke sensors, temperature sensors and audible and visual alarms. When the smoke sensor detects that the smoke concentration exceeds the preset fire smoke concentration, or when the temperature sensor detects that the temperature exceeds the preset fire temperature, the electric fireproof window closer is triggered to close the movable window sash, and the audible and visual alarm is triggered to issue an audible and visual alarm.

[0010] As a preferred technical solution of this utility model, a magnetic absorbing piece is fixedly embedded at the corner position of the receiving platform, and an iron piece is fixedly embedded at the position corresponding to the magnetic absorbing piece in the frame.

[0011] As a preferred technical solution of this utility model, the side of the fixed window frame and the frame connected by the fireproof hinge is also equipped with an anti-detachment rotating component. The anti-detachment rotating component includes a fixed rotating cylinder and a rotating pin. The outer side of the fixed rotating cylinder is fixedly connected to the fixed window frame, the top side of the rotating pin is fixedly connected to the frame, and the bottom end of the rotating pin is rotatably inserted into the interior of the fixed rotating cylinder.

[0012] As a preferred technical solution of this utility model, the fireproof glass is a multi-layer composite fireproof glass, including double-layer high-strength glass, with a fireproof adhesive layer disposed between the double-layer high-strength glass.

[0013] As a preferred embodiment of this utility model, the high-performance aluminum alloy frame is externally fixed with a fireproof protective layer, which is a fireproof ceramic fiber board or a vermiculite fireproof board.

[0014] As a preferred technical solution of this utility model, the cross-section of the high-performance aluminum alloy frame profile is a multi-chamber structure, and each chamber is filled with flame-retardant expansion core material.

[0015] As a preferred technical solution of this utility model, the high-performance aluminum alloy frame is made of 6A13 aluminum alloy or 6H13 aluminum alloy.

[0016] As a preferred embodiment of this invention, the sealing strip is a silicone rubber strip with added flame retardant.

[0017] In summary, this utility model has the following beneficial effects: With excellent fire resistance, the high-performance aluminum alloy frame is made of 6A13 / 6H13 high-performance fire-resistant profiles, combined with a fireproof protective layer and flame-retardant expansion core material, with a strength retention rate of ≥80% at 350℃; multi-layer composite fireproof glass and flame-retardant sealing strips form a complete fire barrier.

[0018] The fixed window frame features a dual-sensor layout on both the inner and outer sides, enabling simultaneous monitoring of indoor and outdoor fire spread and avoiding sensor lag. The electric window closer is equipped with a backup power supply, allowing it to continue operating normally after a power outage. It also features a short window closing response time and, in conjunction with audible and visual alarms, provides more time for evacuation.

[0019] The anti-detachment rotating component, through the combination of a "fixed rotating cylinder + rotating pin", limits the displacement of the window sash after high-temperature deformation, preventing it from detaching; the corner magnetic clasp and iron plate adsorption design enhance the fit between the window sash and the window frame, solving the gap problem caused by the softening of the sealing strip, providing double protection for structural stability.

[0020] Multi-chamber profiles are filled with intumescent core material and covered with a fireproof protective layer, which effectively reduces the thermal conductivity of aluminum alloy; the fireproof adhesive layer of multi-layer fireproof glass expands when heated, and together with the intumescent sealant, it completely blocks the penetration of flames and smoke, avoiding the phenomena of "fire spread" and "smoke spread".

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0024] This utility model provides an aluminum alloy fire-resistant window, including a fixed window frame 1 and a movable window sash 2; Both the fixed window frame 1 and the movable window sash 2 have high-performance aluminum alloy frames 3; the high-performance aluminum alloy frames are made of 6A13 aluminum alloy or 6H13 aluminum alloy. All three types of profiles are heat treated with T6, with a tensile strength ≥320MPa and a strength retention rate ≥80% at 350℃, combining high strength and high temperature stability.

[0025] The high-performance aluminum alloy frame profile has a multi-chamber structure, with each chamber filled with flame-retardant intumescent core material. Expanded graphite-based core material or expanded vermiculite core material is selected. The flame-retardant intumescent core material expands rapidly when heated, filling the gaps inside the chamber, which not only enhances the profile's resistance to deformation but also blocks heat convection inside the chamber, further improving the heat insulation effect.

[0026] The high-performance aluminum alloy frame is externally fixed with a fireproof protective layer, which is either a fireproof ceramic fiber board or a vermiculite fireproof board. The fireproof ceramic fiber board is 3-5mm thick, with a temperature resistance of ≥1200℃ and a thermal conductivity of ≤0.15W / (m・K). The vermiculite fireproof board is 4-6mm thick, with a temperature resistance of ≥1000℃ and is non-combustible when heated. The fireproof protective layer is bonded to the outer surface of the high-performance aluminum alloy frame with high-temperature fire-resistant adhesive, which can delay the conduction of high temperature to the interior of the profile and reduce the attenuation of the profile strength.

[0027] The movable window sash 2 includes an outer frame 3 and fire-resistant glass 4 set inside the frame 3. The fire-resistant glass 4 has a multi-layer composite structure, including double-layer high-strength tempered glass, with a fire-resistant adhesive layer between the double-layer high-strength tempered glass. The fire-resistant adhesive layer is made of organic fire-resistant gel, which expands rapidly when exposed to temperatures above 70°C, with an expansion ratio of ≥10 times, filling the gaps between the glass and forming a heat insulation layer to isolate flames and heat transfer.

[0028] Fire-resistant sealant is used to fill the gap between the frame 3 and the fireproof glass 4. The sealant is heat-expanding and has an expansion factor of ≥5 times when heated, which further blocks the flame from penetrating from the edge of the glass.

[0029] A raised support platform 5 is provided on one side of the inner side of the fixed window frame 1. The support platform 5 is used to support the outer side of the frame 3 of the movable window sash 2. The height of the support platform 5 is adapted to the thickness of the frame 3. When the movable window sash 2 is closed, the frame 3 and the inner side of the fixed window frame 1 are flush. The support platform 5 is provided with a sealing groove, and a high-temperature resistant sealing strip 6 is installed in the sealing groove. The sealing strip 6 is a silicone rubber strip with added flame retardant, with a temperature resistance of ≥300℃, good flame retardant effect, and is not easy to soften and burn in a fire, ensuring the continuity of the seal.

[0030] A groove is provided at the corner of the receiving platform 5, and a magnetic locating piece 12 is fixedly embedded in the groove. An iron piece is fixedly embedded in the frame 3 at the position corresponding to the magnetic locating piece 12. When the movable window sash 2 is closed, the magnetic locating piece 12 and the iron piece adhere to each other, further enhancing the fit between the frame 3 and the receiving platform 5 and preventing sealing gaps caused by slight softening of the sealing strip 6 under high temperatures. It should be noted that the magnetic locating piece 12 is a non-strong magnetic locating piece 12. The magnetic force of the magnetic locating piece 12 needs to be considered in practical use; therefore, a weak magnetic locating piece 12 is used to increase the closing fit and avoid difficulty in opening and closing the movable window sash 2 due to strong magnetic force.

[0031] A fireproof hinge 15 connects one side of the fixed window frame 1 and one side of the frame 3. The fireproof hinge 15 is made of stainless steel and filled with fireproof filler, with a temperature resistance of ≥800℃ to prevent hinge failure at high temperatures. A fireproof lock 7 is installed between the other side of the fixed window frame 1 and the other side of the frame 3. The fireproof lock 7 includes a limiting part fixed on the fixed window frame 1 and a rotating part set on the frame 3. By controlling the rotation of the rotating part, the rotating part can be limited to or disengaged from the limiting part. The entire fireproof lock 7 is made of brass, which is not easy to stick at high temperatures, ensuring normal opening and closing.

[0032] On one side of the fireproof hinge 15 connecting the fixed window frame 1 and the frame 3, there is also an anti-detachment rotating component. The anti-detachment rotating component includes a fixed rotating cylinder 13 and a rotating pin 14. The fixed rotating cylinder 13 is a stainless steel cylinder, and the rotating pin 14 is a galvanized steel column. The outer side of the fixed rotating cylinder 13 is welded and fixed to the fixed window frame 1, and the top side of the rotating pin 14 is welded and fixed to the frame 3. The bottom end of the rotating pin 14 is rotatably inserted into the interior of the fixed rotating cylinder 13. This structure can limit the displacement of the window sash when the movable window sash 2 is closed or deformed by high temperature, prevent the window sash from detaching from the fixed window frame 1, and improve the structural stability.

[0033] An electric fireproof window closer 8 is connected between the top edge of the fixed window frame 1 and the top edge of the side frame 3. The electric fireproof window closer 8 has a built-in 12V backup power supply, which can maintain operation for at least 30 minutes after power failure to prevent failure during power outages in fires. The window closing response time is ≤30s to ensure rapid closing of the window sash.

[0034] Smoke sensors 9, temperature sensors 10, and audible and visual alarms 11 are fixed to the inner and outer sides of the fixed window frame 1 using screws and other components. When the smoke sensor 9 detects that the smoke concentration exceeds the preset fire smoke concentration, or when the temperature sensor 10 detects that the temperature exceeds the preset fire temperature, the electric fireproof window closer 8 is triggered to close the movable window sash 2, and the audible and visual alarm 11 is triggered to sound an alarm. The preset fire smoke concentration threshold for the smoke sensor 9 is set to 0.15-0.3 mg / m³, which complies with GB 50116-2013 "Code for Design of Automatic Fire Alarm Systems". The preset fire temperature threshold for the temperature sensor 10 is set to 68℃, which is a common critical temperature in the early stages of a fire, thus avoiding false triggering. The parameters for the audible and visual alarm are: sound decibel ≥ 85dB and light intensity ≥ 15cd, ensuring long-distance warning for personnel evacuation. In the event of a power outage due to a fire, the smoke sensor 9, temperature sensor 10, and audible and visual alarm 11 are all powered by the backup power supply of the electric fireproof window closer 8.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
