Description

Technical Field

[0001] The present invention relates to the technical field of fireproof windows, in particular to an energy-saving and fireproof window frame with a composite structure and an inward-opening window having the same. Background Art

[0002] Passive building is a new energy-saving concept developed based on low-energy buildings. Passive homes achieve efficient thermal insulation through the use of highly insulating materials and doors and windows with low heat transfer coefficients, employing optimized construction methods. They also utilize clean energy and heat dissipation from household appliances to provide indoor heat, reducing or eliminating the use of actively supplied energy to achieve a comfortable temperature. Doors and windows account for a significant portion of building energy consumption. Given the energy-saving performance requirements of passive buildings, existing commercially available doors and windows are no longer sufficient, necessitating urgent energy optimization. Among windows and doors, fireproofing is the most challenging component to meet the requirements of passive buildings. Existing fireproofing struggles to balance energy efficiency and fire resistance. While common steel fireproofing offers good fire resistance, it cannot meet the increasing energy-saving demands. While solid wood fireproofing meets energy-saving requirements, it suffers from poor weather resistance and can fade, deform, and crack over time. Furthermore, prolonged exposure to open flames poses safety risks. In addition, most of the wooden fireproof windows currently on the market open outwards and have poor air tightness.

[0003] In order to solve the above problems and improve the fire resistance of wooden windows, it is necessary to develop a new type of composite structure energy-saving fireproof window frame and an inward-opening window with the same. Summary of the Invention

[0004] The present invention aims to provide a composite energy-saving fireproof window frame and an inward-opening window having the same, thereby addressing the technical problems of poor weather resistance and fire resistance of existing wooden fireproof windows. The various technical effects achieved by the preferred technical solution among the various technical solutions provided by the present invention are detailed below.

[0009] A fireproof buckle, comprising a metal core and a plastic coating layer located outside the metal core; the fireproof buckle can be snapped onto the window frame finish or the window sash finish and inserted into the window frame fireproof insulation board or the window sash fireproof insulation board through the window frame high-temperature resistant metal pressure plate or the window sash high-temperature resistant metal pressure plate.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] As a further improvement of the present invention, a strip groove is formed on the inner side of the window frame facing and / or the window sash facing along its length direction, and the fireproof buckle can be snap-fitted with the window frame facing and / or the window sash facing through the strip groove;

[0012] And / or, the window frame facing and / or the window sash facing are made of at least one of aluminum, polyvinyl chloride, fiberglass, and glass fiber polyurethane.

[0013] As a further improvement of the present invention, the two opposite sides of the fireproof buckle are partially recessed to form symmetrically arranged slots, and the fireproof buckle is engaged with the strip groove via the slots.

[0014] As a further improvement of the present invention, the upper surface of the window frame fireproof wooden profile is partially recessed near one side of the window frame fireproof insulation board to form a protective groove, and an aerogel felt is arranged in the protective groove. The window frame high-temperature resistant metal pressure plate can be fixedly connected to the window frame fireproof wooden profile through the aerogel felt.

[0015] As a further improvement of the present invention, a first mounting groove and a second mounting groove are formed on the window frame high temperature resistant metal pressing plate, and the first mounting groove and the second mounting groove are both fixedly connected to the window frame fireproof insulation board through the protective groove;

[0016] A fireproof rubber strip is fixedly installed in the first installation groove, and a first sealing strip is fixedly installed in the second installation groove;

[0017] When the window sash component is in a closed state, the fireproof rubber strip and the first sealing strip are both squeezed and deformed.

[0018] As a further improvement of the present invention, an embedding groove is formed between the window frame finish and the window frame high-temperature resistant metal pressure plate, and the first sealing strip can be connected to the window frame finish through the embedding groove and cover the fireproof buckle.

[0019] As a further improvement of the present invention, a second sealing strip is further provided between the window sash facing and the window sash high temperature resistant metal pressure plate, and at least a portion of the second sealing strip is located outside the fireproof buckle and can shield the fireproof buckle.

[0020] As a further improvement of the present invention, a first airtight adhesive strip is embedded on the side of the window frame facing close to the window sash facing, and a second airtight adhesive strip is embedded on the side of the window sash fireproof wood profile close to the window frame fireproof wood profile;

[0025] Compared with traditional window frame structures, this composite energy-saving and fireproof window frame effectively overcomes the lack of weather resistance of traditional wooden window frames by installing high-temperature resistant metal pressure plates and finishes on the exterior of fireproof wooden profiles, thereby extending the service life of the window frames and making the windows more beautiful. Furthermore, the high-temperature resistant metal pressure plates not only help improve the structural strength of the window frames, but also effectively isolate the wooden profiles and finishes, preventing the wooden profiles and insulation boards from direct contact with open flames, further enhancing their fireproofing effects. In addition to fixing the finishes, the fireproof card can also prevent electrochemical reactions between the two metals, reduce noise, and avoid cold bridges, giving the window frames better insulation. The sealing strips and fireproof rubber strips located throughout the window frame not only provide good airtightness but also have good fireproofing effects. Some of these strips can rapidly expand at high temperatures and isolate the wooden profiles from open flames, preventing smoke from entering the room. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0035] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0036] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention depending on the specific circumstances.

[0037] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] The present invention provides a composite energy-saving and fireproof window frame, comprising a window frame member 1, a window sash member 2, and a fireproof clip 3. The fireproof clip 3 comprises a metal core and a plastic coating. The fireproof clip 3 can be used to secure the window frame facing 14 and / or the window sash facing 24 to the exterior of the fireproof wood profile, thereby improving the weather resistance and service life of the wooden window and enhancing the aesthetics of the window frame structure.

[0039] Specifically, the above-mentioned window frame component 1 includes a window frame fireproof wooden profile 11, a window frame fireproof insulation board 12, a window frame high-temperature resistant metal pressure plate 13 and a window frame finish 14; the window frame fireproof insulation board 12 is located between the window frame fireproof wooden profile 11 and the window frame high-temperature resistant metal pressure plate 13, and the window frame finish 14 is fixedly arranged outside the window frame high-temperature resistant metal pressure plate 13; the above-mentioned window sash component 2 includes a window sash fireproof wooden profile 21, a window sash fireproof insulation board 22, a window sash high-temperature resistant metal pressure plate 23 and a window sash finish 24; the window sash fireproof insulation board 22 is located between the window sash fireproof wooden profile 21 and the window sash high-temperature resistant metal pressure plate 23, and the window sash finish 24 is fixedly arranged outside the window sash high-temperature resistant metal pressure plate 23. The fireproof buckle 3 includes a metal core and a plastic coating layer located outside the metal core; the fireproof buckle 3 can be snapped into the window frame finish 14 or the window sash finish 24 and inserted into the window frame fireproof insulation board 12 or the window sash fireproof insulation board 22 through the window frame high-temperature resistant metal pressure plate 13 or the window sash high-temperature resistant metal pressure plate 23.

[0040] Specifically, the window frame fireproof insulation board 12 and / or the window sash fireproof insulation board 22 can be WHMF-41 produced by Weihe Thermal Energy. This product is non-flammable, has excellent thermal insulation properties, excellent pressure resistance, and excellent fire resistance. It can also maintain excellent thermal insulation performance (thermal conductivity 0.03 W / (m·K)) even at high temperatures of 800°C.

[0041] The window frame heat-resistant metal pressure plate 13 and the window sash heat-resistant metal pressure plate 23 are both made of stainless steel, such as ASTM SA213 / TP310S high-temperature stainless steel. The thermal conductivity of ordinary carbon steel is 45 W / m·°C, while the thermal conductivity of stainless steel is 16.2 W / m·°C. Therefore, the window frame heat-resistant metal pressure plate 13 and the window sash heat-resistant metal pressure plate 23 made of stainless steel have the advantages of fire resistance and energy conservation.

[0042] The high-strength, heat-resistant metal pressure plate structure on the window frame and sash not only protects the fireproof insulation board inside from deformation, but also maintains high strength even at high temperatures due to its low thermal conductivity and high melting point. Even after the veneer melts at high temperatures, the heat-resistant metal pressure plate not only continues to provide strong support for the window frame structure, but also isolates the wood and insulation board from contact with open flames, achieving better fire protection.

[0043] It should be noted that the above-mentioned window frame high-temperature resistant metal pressure plate 13 and / or window sash high-temperature resistant metal pressure plate 23 are provided with holes, which can be fixed by screws outside the window frame fireproof insulation board 12 and / or window sash fireproof insulation board 22.

[0044] As an optional embodiment, a strip groove is formed on the inner side of the window frame finish 14 and / or the window sash finish 24 along its length direction, and the fireproof buckle 3 can be snap-connected with the window frame finish 14 and / or the window sash finish 24 through the strip groove.

[0045] As an optional embodiment, the two opposite sides of the fireproof buckle 3 are partially recessed to form symmetrically arranged slots 31, and the fireproof buckle 3 is connected to the strip groove through the slots 31, such as Figure 1 shown.

[0046] In this embodiment and similar embodiments, the metal core of the fireproof clip 3 is an ASTM SA213 / TP310S steel core. Because the fireproof clip 3 has a plastic-coated exterior, direct contact between two dissimilar metal materials is prevented during use, effectively preventing any galvanic reactions between the metals and reducing potential noise issues associated with the window frame structure.

[0047] The metal core within the fireproof clip 3 is a wood screw. During installation, it can be directly connected to the main body of the window frame and / or sash (i.e., the fireproof wood profile). This not only effectively secures the stainless steel pressure plate and fireproof insulation board, but also prevents direct contact between the finish and the main body, reducing installation and maintenance costs while also preventing the cold bridge effect. In high-temperature environments, the outer plastic coating burns or melts, but the internal metal core maintains its shape, providing a stable and secure fit.

[0048] Since the main function of the window frame facing 14 and the window sash facing 24 is to protect the internal wooden structure while also providing a certain decorative effect, in this embodiment and similar embodiments, the materials of the window frame facing 14 and the window sash facing 24 can be adjusted according to actual needs. The processing materials of the two can be the same or different. Generally, the facings are aluminum. However, other materials such as PVC, fiberglass reinforced plastic, and fiberglass polyurethane can also be used to make the facings.

[0049] As an optional embodiment, the upper surface of the window frame fireproof wood profile 11 is partially recessed near the window frame fireproof insulation board 12 to form a protective groove 111, and an aerogel felt 4 is provided in the protective groove 111. The window frame high temperature resistant metal pressure plate 13 can be fixedly connected to the window frame fireproof wood profile 11 through the aerogel felt 4. Figure 2 shown.

[0050] Specifically, the aerogel felt 4 has excellent thermal insulation and high-temperature resistance. Its thermal conductivity at room temperature is as low as 0.016 to 0.018 W / (m·K), making it usable in temperatures ranging from -200°C to 1300°C. Placing the aerogel felt 4 between the window frame's high-temperature-resistant metal platen 13 and the window frame's fireproof wood profile 11 prevents the cold bridge effect caused by the stainless steel material from affecting the window's thermal insulation performance. It also protects the window frame's fireproof wood profile 11 in the event of a fire, preventing it from burning due to the excessively high surface temperature of the window frame's high-temperature-resistant metal platen 13.

[0051] As an optional embodiment, a first mounting groove 131 and a second mounting groove 132 are formed on the window frame high-temperature resistant metal pressing plate 13. The first mounting groove 131 and the second mounting groove 132 are fixedly connected to the window frame fireproof insulation board 12 via the protective groove 111. A fireproof rubber strip 133 is fixedly installed in the first mounting groove 131, and a first sealing strip 134 is fixedly installed in the second mounting groove 132.

[0052] When the window sash component 2 is in a closed state, the fireproof rubber strip 133 and the first sealing strip 134 are squeezed by the window sash component 2 and deformed.

[0053] It should be noted that the fireproof rubber strip 133 has the property of foaming and expanding when exposed to fire, which can play a role in isolating open flames and smoke. The first sealing strip 134 is a rubber strip with good elasticity and weather resistance, which can help improve the airtightness and watertightness of the window frame structure.

[0054] In this embodiment and other similar embodiments, the first sealing strip 134 is a rubber strip made of EPDM material.

[0055] Specifically, the inner wall of the first mounting groove 131 is provided with a strip-shaped groove, and the outer side of the portion of the fireproof rubber strip 133 that is inserted into the first mounting groove 131 is formed with a barb that matches the strip-shaped groove. The fireproof rubber strip 133 can then use the deformability of the barb to press against the inner wall of the first mounting groove 131, thereby improving the connection between the two and further enhancing the flame retardancy and sealing effect.

[0056] The structures of the second mounting groove 132 and the first sealing strip 134 are the same as above.

[0057] As an optional embodiment, an embedding groove 141 is further formed between the window frame finish 14 and the window frame high-temperature resistant metal pressure plate 13, and the first sealing strip 134 can be connected to the window frame finish 14 through the embedding groove 141 and cover the fireproof buckle 3.

[0058] This structure can effectively prevent rainwater from penetrating into the area where the fireproof buckle 3 is located through the gap formed between the window frame finish 14 and the window frame high-temperature resistant metal pressure plate 13, thereby protecting the fireproof buckle 3 and preventing the fireproof buckle 3 from being corroded by rainwater.

[0059] As an optional embodiment, a second sealing strip 5 is further provided between the window sash facing 24 and the window sash high temperature resistant metal pressure plate 23 , and at least a portion of the second sealing strip 5 is located outside the fireproof buckle 3 and can shield the fireproof buckle 3 .

[0060] This structure can prevent moist air or flying insects from entering the area where the fireproof buckle 3 is located, further protecting the fireproof buckle 3 and providing the window sash component 2 with better air tightness and water tightness.

[0061] In this embodiment and other similar embodiments, the second sealing strip 5 is a rubber strip made of EPDM material.

[0062] As an optional embodiment, a first airtight tape 6 is embedded in the side of the window frame finish 14 close to the window sash finish 24, and a second airtight tape 7 is embedded in the side of the window sash fireproof wood profile 21 close to the window frame fireproof wood profile 11; when the window sash component 2 is in a closed state, the window sash component 2 is connected to the window frame component 1 via the first airtight tape 6 and the second airtight tape 7, and at this time the first airtight tape 6 and the second airtight tape 7 are squeezed and deformed.

[0063] The first airtight adhesive strip 6 and the second airtight adhesive strip 7 cooperate with each other to effectively improve the airtightness and watertightness of the window frame structure.

[0064] In this embodiment and other similar embodiments, the first airtight rubber strip 6 and the second airtight rubber strip 7 are both made of EPDM material.

[0065] As an optional embodiment, a groove for installing the glass 8 is formed between the window sash fireproof wood profile 21 and the window sash finish 24, and the gap between the outer side of the glass 8 and the window sash fireproof wood profile 21 and the window sash finish 24 is filled with EPDM strips 9, such as Figure 1 and Figure 3 ( Figure 3 The middle glass 8 is not shown).

[0066] Specifically, the glass 8 is a multi-layer vacuum glass 8 .

[0067] The energy-saving and fireproof window frame of the composite structure has good thermal insulation function when in use, such as Figure 4 As shown in the figure, the temperature distribution diagram of the composite structure energy-saving fireproof window frame is shown in the figure when the outdoor environment is -20℃ and the indoor environment is 20℃. When a fire occurs outdoors and the temperature rises to 800℃, the temperature distribution diagram is shown in the figure. Figure 5 As shown, at this time, the window frame structure can effectively block heat conduction, thereby reducing the indoor temperature and having a good fire prevention function.

[0068] The present invention also provides an inward opening window, comprising an energy-saving and fireproof window frame of the composite structure described in any one of the above items, such as Figure 6 shown.

[0069] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
