Description

Technical Field

[0001] This application relates to the technical field of fire-resistant windows, and in particular to a strip-type heat-insulating fire-resistant window and its manufacturing process. Background Technology

[0002] In the field of building fire safety, aluminum alloy insulated windows are widely used due to their excellent thermal insulation and sound insulation properties. However, traditional aluminum alloy windows have significant performance shortcomings under high temperatures in a fire. Their profiles are mainly hollow cavity structures; the metal material itself conducts heat quickly and has a low melting point. In a fire, it rapidly becomes a heat conduction channel, softening and deforming. This causes the entire window to lose its fire resistance and thermal insulation properties in a short time, failing to effectively block the spread of flames and high-temperature smoke, thus affecting its fire safety performance.

[0003] To improve the fire resistance of aluminum alloy windows, the industry has implemented numerous technical improvements. One common solution is to install a fire-resistant sealing strip at the joint between the window sash and the frame. This fire-resistant sealing strip ensures airtightness and watertightness at room temperature, and expands when exposed to heat, thus sealing any gaps that may arise from heat deformation of the window frame, thereby slowing down the rate at which fire can penetrate the window through these gaps.

[0004] However, the immense thermal and mechanical stresses generated by a fire can easily cause complex relative deformations between the window sash and frame. The fire-resistant sealing strip at the overlap line has limited expansion volume and strength, making it difficult to fill the complex gaps created by deformation, thus forming leakage channels. Secondly, the fire-resistant sealing strip itself is at risk of carbonization failure, detachment, or being blown away under extreme high temperatures and direct flame exposure. Once the connection fails, the entire window's sealing barrier will be breached. Therefore, existing technical solutions have significant problems with insufficient sealing reliability and limited fire resistance integrity under complex fire conditions, and the overall fire resistance performance needs to be significantly improved. Summary of the Invention

[0005] To further improve the fire resistance performance of fire-resistant windows, this application provides a strip-insulated fire-resistant window and its manufacturing process.

[0006] This application provides a strip-type insulated fire-resistant window and its manufacturing process, which adopts the following technical solution, including: A glass module consists of several glass units; The profile module includes a window frame and a mullion connected within the window frame. The mullion divides the interior of the window frame into multiple panes. The mullion includes several horizontally arranged mullion beams and vertically arranged mullion beams. The window frame includes multiple frame beams connected end to end. The fireproof sealing module includes a first expansion strip and a second expansion strip; The central mullion is provided with a first connecting cavity and a first central cavity. Both sides of the central mullion are provided with first connecting cavities. The first central cavity is connected between the two first central cavities. A first barrier strip is provided at the connection between the first connecting cavity and the first central cavity. The frame beam is provided with a second connecting cavity and a second central cavity. The second connecting cavity is located near the central mullion, and the second central cavity is connected to one side of the second connecting cavity. A second barrier strip is provided at the connection between the second connecting cavity and the second central cavity. Both the first connecting cavity and the second connecting cavity are open on the side facing the window pane to allow for side mounting of the glass unit; Both the first connecting cavity and the second connecting cavity are provided with a first expansion strip, and both the first middle cavity and the second middle cavity are provided with a second expansion strip, with the first expansion strip positioned close to the adjacent second expansion strip.

[0007] By adopting the above technical solution, the arrangement of the fire-resistant sealing module is changed from the traditional single-seal at the joint between the window sash and the window frame to a reorganized arrangement within the mullion and frame beams, enabling the mullion and frame beams to perform the fire-resistant sealing function themselves. First connecting cavities are provided on both sides of the mullion, and the two first connecting cavities are connected through a first central cavity, ensuring that the glass units of adjacent panes on both sides of the mullion receive symmetrical embedded sealing support. Second connecting cavities and a second central cavity are provided inside the frame beam, creating a unified perimeter and internal partition area for the entire window. Fire-resistant cavity layout: In the event of a fire, the first expansion strip in the first or second connecting cavity expands preferentially at the joint between the glass and the profile, sealing the gaps caused by the burning of the sealing strip. The second expansion strip in the first or second central cavity expands in the central region of the profile to form a dense carbonized heat insulation layer, effectively blocking heat conduction to the indoor side through the metal cavity. The first expansion strip is set close to the adjacent second expansion strip, so that the two expansion seals are connected continuously. This significantly improves the fire resistance integrity and fire insulation performance of the entire window under fire conditions.

[0008] Optionally, each side of the glass unit is provided with a reinforcing bracket, which is connected to the first connecting cavity or the second connecting cavity. The reinforcing bracket includes a bracket body and a glass pad connected to the bracket body. The glass pad is located between the glass unit and the bracket body.

[0009] By adopting the above technical solution, a reinforcing bracket is set up to rigidly support the glass unit, replacing the traditional plastic pad. The bracket body of the reinforcing bracket provides a stable support foundation for the glass unit, while the glass pad is placed between the glass unit and the bracket body. It plays a role in buffering and positioning while avoiding stress concentration caused by direct hard contact between the glass and metal. In the high-temperature environment of a fire, the reinforcing bracket can maintain sufficient structural strength, slow down the speed at which the fireproof glass will shift or fall due to the softening of the profile, so that the glass unit maintains the correct installation position during the fire resistance time, and ensures that the fire resistance integrity of the entire window is not damaged by glass falling off during the fire resistance period.

[0010] Optionally, fireproof cotton strips are provided in both the first and second connecting cavities, and fireproof cotton strips are provided on both sides of the glass unit; the connection gap between the glass unit and the first and second connecting cavities is also filled with sealant.

[0011] By adopting the above technical solution, fireproof cotton strips are installed on both sides of the glass unit. In the event of a fire, flames and high-temperature gases can be effectively blocked from entering through the gap between the glass and the mullion. At the same time, the glass unit is flexibly clamped to absorb displacement deformation caused by thermal expansion differences. The sealant filled in the joint ensures the airtightness and watertightness of the glass installation part at room temperature, and can also provide a certain degree of bonding and fixing effect in the early stage of fire.

[0012] Optionally, the central beam is further provided with a support cavity, and a plurality of support cavities are spaced apart on the periphery of the first central cavity; Each of the support cavities is provided with a first support strip, which is snapped into the support cavity.

[0013] By adopting the above technical solution, a first support strip is installed inside the support cavity. At normal temperature, the first support strip provides additional structural rigidity to the mullion beam. When the mullion softens and loses its load-bearing capacity under the high temperature of a fire, multiple first support strips distributed inside the mullion form an independent skeleton support system, which undertakes the task of supporting the window frame and fixing the glass unit. This effectively prevents the profile from collapsing or deforming completely at high temperatures and ensures that the entire window maintains its structural integrity within the specified fire resistance time limit.

[0014] Optionally, a number of stabilizing branch pipes are also connected to one side of the muzzle, and a second supporting strip is inserted inside the stabilizing branch pipe. The second supporting strip is snapped into the stabilizing branch pipe.

[0015] By adopting the above technical solution, an additional stable branch pipe is connected to one side of the mullion and a second support strip is installed in it, so that the mullion can obtain additional lateral support during a fire. This enhances the mullion's resistance to bending and torsion under high temperature deformation conditions, prevents the mullion from shifting or twisting due to fire on one side, and thus improves the overall stability of the profile module.

[0016] Optionally, the glass unit includes two glass plates spaced apart, with a connecting strip between the two glass plates, and the connecting strip is located on the side of the glass plates, and at least one glass plate is made of heat-insulating and fire-resistant material.

[0017] By adopting the above technical solution, the glass unit adopts a hollow double glass panel structure. The two glass panels are connected by side connecting strips to form a hollow layer, so as to improve the thermal insulation and sound insulation performance of the fire-resistant window. At least one glass panel is made of heat-insulating and fireproof material, which can withstand high temperature thermal shock in a fire without cracking or falling off, forming the first barrier against flames.

[0018] Optionally, a heat-conducting bracket is provided in the first central cavity. The heat-conducting bracket includes a heat-conducting sheet and a heat-conducting support strip connected to each other. The heat-conducting support strip is arranged perpendicular to the heat-conducting sheet. The heat-conducting sheet is snapped into the first central cavity, and the heat-conducting support strip is snapped into the second expansion strip. Both ends of the heat-conducting sheet are provided with heat-conducting edges, and one end of the heat-conducting edge extends to the outside of the central support.

[0019] By adopting the above technical solution, the heat-conducting sheet is inserted into the first central cavity, and the heat-conducting support strip is inserted into the second expansion strip, thus fixing the heat-conducting bracket and the expansion strip together. The heat-conducting edges at both ends of the heat-conducting sheet extend to the outside of the central support. In case of fire, the exposed heat-conducting edges heat up rapidly, and the heat is quickly conducted to the entire heat-conducting sheet, and then evenly transferred to the second expansion strip that wraps it through the heat-conducting support strip. This allows the second expansion strip to reach its expansion reaction temperature almost simultaneously, resulting in uniform and sufficient expansion, efficiently filling the first central cavity and forming a high-quality partition.

[0020] Optionally, the sidewall of the heat-conducting support strip is provided with mating protrusions, and multiple mating protrusions are spaced apart along the length of the heat-conducting support strip; the second expansion strip is provided with a snap-fit ​​groove for the heat-conducting support strip to snap into, and the inner sidewall of the snap-fit ​​groove is provided with a connecting groove for the mating protrusions to snap into, and multiple connecting grooves are provided corresponding to the mating protrusions.

[0021] By adopting the above technical solution, and by setting spaced-distributed mating protrusions on the side wall of the heat-conducting support strip and opening corresponding connecting grooves on the inner side wall of the snap-fit ​​groove of the second expansion strip, multi-point snap-fit ​​positioning along the length direction between the heat-conducting support strip and the second expansion strip is achieved, so that a reliable mechanical interlocking connection is formed between the two. When the profile undergoes thermal deformation and vibration during a fire, the multi-point snap-fit ​​structure can effectively prevent the second expansion strip from separating or misaligning from the heat-conducting support strip, thereby ensuring the stable installation of the second expansion strip in the first central cavity, so that the second expansion strip can remain in the designed position and work reliably.

[0022] Optionally, a heat-conducting support is also provided in the second central cavity.

[0023] By adopting the above technical solution, a heat-conducting bracket is installed in the second central cavity, so that the second expansion strip in the second central cavity can also achieve efficient thermal connection and mechanical fixation in the second central cavity through the heat-conducting bracket, thereby achieving synchronous, uniform and reliable expansion in a fire.

[0024] This application also provides a manufacturing process for a strip-type insulated fire-resistant window, used to produce the strip-type insulated fire-resistant window as described above.

[0025] In summary, this application includes at least one of the following beneficial effects: 1. This application constructs multiple expansion sealing lines that continuously cover the glass unit embedded part to the center of the profile module by setting a first expansion strip and a second expansion strip at corresponding positions in the mullion and frame beam, and setting the first expansion strip close to the adjacent second expansion strip, which significantly improves the fire resistance integrity and fire insulation performance of the entire window under fire conditions. 2. By setting up a support cavity and inserting a first support strip inside the support cavity, and by connecting a stable branch pipe to the side of the mullion and inserting a second support strip, this application enhances the structural rigidity and deformation resistance of the mullion, and can better maintain structural integrity at high temperatures, providing a stable support foundation for the fireproof sealing system. 3. This application provides a heat-conducting bracket in the first and second central cavities, and uses the heat-conducting edges at both ends of the heat-conducting sheet to extend to the outside of the central support to guide and disperse heat. At the same time, the heat-conducting support strip is snapped into the inside of the second expansion strip to form an internal support, preventing the second expansion strip from breaking and scattering during the process of thermal expansion. Even if the second expansion strip breaks from the middle position, the broken parts can be stably maintained in the designed position and function normally. Attached Figure Description

The glass pad 42 is provided on one side of the bracket body 41. In this embodiment, the glass pad 42 is made of high-temperature resistant calcium silicate board.

[0037] refer to Figure 2Fireproof cotton strips 35 are provided in both the first connecting cavity 221 and the second connecting cavity 211, and fireproof cotton strips 35 are also provided on both sides of the glass unit 1. The fireproof cotton strips 35 are filled in the gap between the outer surface of the glass plate 11 of the glass unit 1 and the inner wall of the first connecting cavity 221 or the second connecting cavity 211. The fireproof cotton strips 35 can be made of aluminum silicate ceramic fiber, rock wool, or glass wool. The connection gap between the glass unit 1 and the first connecting cavity 221 and the second connecting cavity 211 is also filled with sealant 36. In this embodiment, the sealant 36 is a weather-resistant silicone sealant.

[0038] refer to Figure 3 The central mullion 22 has a support cavity 223 machined inside, and several support cavities 223 are spaced apart around the first central cavity 222. In this embodiment, there are three support cavities 223 in one central mullion 22. In other embodiments, there may be two, three, or six support cavities 223. At least one support cavity 223 is fitted with a first support strip 5, which is snapped into the support cavity 223. In this embodiment, only one first support strip 5 is fitted into one central mullion 22, and the remaining support cavities 223 may be fitted with second expansion strips 32 or left empty. The first support strip 5 is made of 1.5mm thick galvanized steel pipe with a rectangular groove cross-section. It is inserted into the support cavity 223 and snapped into and fixed to the support cavity 223, or it may be reinforced with self-tapping screws.

[0039] refer to Figure 3 Several stabilizing branch pipes 23 are connected to one side of the mullion. These branch pipes 23 are fixed to the outer surface of the side wall of the longitudinally placed mullion 22 by welding or screws, extending along the length of the mullion 22.

In this embodiment, the stabilizing branch pipe 23 is made of aluminum alloy, and the second support strip 6 is made of galvanized steel pipe with a rectangular cross-section. Two stabilizing branch pipes 23 are provided. In other embodiments, three or four stabilizing branch pipes 23 may also be provided. When installing a fireproof window, the side of the mullion with the stabilizing branch pipes 23 should face outwards.

[0040] refer to Figure 2Glass unit 1 includes two glass plates 11 spaced apart, connected by a connecting strip 12 located on the side of each glass plate 11, forming a sealed hollow layer between them. In this embodiment, the hollow layer is 12mm thick and filled with dry air or inert gas. At least one glass plate 11 is made of heat-insulating and fire-resistant material. In this embodiment, the outdoor glass plate 11 is made of single-pane non-heat-insulating fire-resistant glass with a thickness of 6mm and a fire resistance integrity of not less than 1.00 hour; the indoor glass plate 11 is made of 5mm thick ordinary tempered glass. In other embodiments, both glass plates 11 can be made of fire-resistant glass.

[0041] The implementation principle of a strip-type heat-insulating and fire-resistant window in Embodiment 1 of this application is as follows: Under normal temperature conditions, the glass unit 1 is inserted into the first connecting cavity 221 or the second connecting cavity 211 through the side and is supported and fixed by the reinforcing bracket 4. The fireproof cotton strip 35 and the sealant 36 form a watertight and airtight seal around the glass. When a fire occurs, the fireproof glass plate 11 on the outdoor side withstands the high temperature impact without cracking, forming the first barrier against flames. The first expansion strip 31 in the connecting cavity begins to expand at about 150°C, sealing the glass inlay gap caused by the ablation of the sealing strip at normal temperature. The second expansion strip 32 in the first middle cavity 222 and the second middle cavity 212 then expands due to heat, forming a dense carbonized heat insulation layer inside the profile module. The first support strip 5 inserted in the support cavity 223 and the second support strip 6 in the stabilizing branch pipe 23 take over the structural support task after the aluminum alloy softens, preventing the window frame from collapsing or deforming.

[0042] Example 2:

[0043] Embodiment 2 of this application provides a strip-type heat-insulating and fire-resistant window.

[0044] refer to Figures 4-6 The difference between Embodiment 2 and Embodiment 1 is that a heat-conducting bracket 7 is provided in the first central cavity 222 and a heat-conducting bracket 7 is also provided in the second central cavity 212.

[0045] refer to Figure 5 and Figure 6The heat-conducting bracket 7 includes a heat-conducting sheet 71 and a heat-conducting support strip 72 connected to each other, with the heat-conducting support strip 72 positioned perpendicular to the heat-conducting sheet 71. In this embodiment, the heat-conducting sheet 71 is made of copper, extending along the length of the central beam 22, and its shape is adapted to the shape of the inner wall of one side of the first central cavity 222 to achieve engagement of the heat-conducting sheet 71 within the first central cavity 222. The heat-conducting support strip 72 is made of copper strip and is welded or riveted to the central region of the heat-conducting sheet 71, forming a T-shaped connection with it. In other embodiments, the heat-conducting sheet 71 and the heat-conducting support strip 72 may also be made of aluminum alloy or stainless steel, and their connection may be integrally stamped.

[0046] refer to Figure 4 and Figure 6 Both ends of the heat-conducting sheet 71 are provided with heat-conducting edges 73, which are flanges formed by bending outwards from both ends of the heat-conducting sheet 71. One end of the heat-conducting edge 73 extends to the outside of the mullion, passing through the through hole or groove reserved on the mullion beam 22 and then exposed to the outer surface of the profile. In the event of a fire, the exposed heat-conducting edge 73 is directly exposed to the fire environment and heats up rapidly. The heat is quickly conducted through the heat-conducting sheet 71 to the heat-conducting support strip 72, and then evenly transferred to the second expansion strip 32 that wraps the heat-conducting support strip 72. This allows the second expansion strip 32 to reach its expansion reaction temperature almost simultaneously, resulting in uniform and sufficient expansion, efficiently filling the first central cavity 222 or the second central cavity 212, forming a high-quality heat insulation layer.

[0047] refer to Figure 6 The heat-conducting support strip 72 has mating protrusions 721 on its sidewall, with multiple mating protrusions 721 spaced apart along the length of the heat-conducting support strip 72. The mating protrusions 721 can be formed on two opposite sidewalls of the heat-conducting support strip 72 by stamping or rolling. A snap-fit ​​groove 321 for the heat-conducting support strip 72 to snap into is provided on one side of the second expansion strip 32. The width and depth of the snap-fit ​​groove 321 match the cross-sectional dimensions of the heat-conducting support strip 72. The heat-conducting support strip 72 is inserted into the second expansion strip 32 through the snap-fit ​​groove 321 to achieve snap-fit. A connecting groove 322 is provided on the inner sidewall of the snap-fit ​​groove 321 for the mating protrusions 721 to snap into. Multiple connecting grooves 322 are provided corresponding to the mating protrusions 721. After the heat-conducting support strip 72 is inserted into the snap-fit ​​groove 321, the mating protrusions 721 are successively embedded into the corresponding connecting grooves 322 to form a multi-point locking mechanism, preventing the heat-conducting support strip 72 from slipping out of the second expansion strip 32 when subjected to force or thermal deformation.

[0048] refer to Figure 4 and Figure 5The structure, material and installation method of the heat-conducting bracket 7 in the second middle cavity 212 are the same as those of the heat-conducting bracket 7 in the first middle cavity 222. The heat-conducting sheet 71 is installed in the second middle cavity 212, and the heat-conducting support strip 72 is installed in the second expansion strip 32 in the second middle cavity 212. The heat-conducting lines 73 at both ends of the heat-conducting sheet 71 extend to the outside of the frame beam 21.

[0049] The implementation principle of the strip-type heat-insulating and fire-resistant window in Embodiment 2 of this application is as follows: When a fire occurs, the exposed heat-conducting edge 73 directly receives the heat from the fire scene, and the heat is quickly and evenly transferred to the entire second expansion strip 32 through the heat-conducting sheet 71 and the heat-conducting support strip 72, so that the second expansion strip 32 expands evenly at the same time; at the same time, the mating protrusion 721 on the heat-conducting support strip 72 and the connecting groove 322 in the snap-fit ​​groove 321 of the second expansion strip 32 form a multi-point locking, so that even if the second expansion strip 32 breaks from the middle position during the heat expansion process, the broken parts can still be stably maintained in the design position and normally perform the fireproof sealing function.

[0050] 2222 Implementation 2:

[0051] Embodiment 3 of this application provides a manufacturing process for a strip-type heat-insulating and fire-resistant window, used to produce the strip-type heat-insulating and fire-resistant window of Embodiment 2.

[0052] The production process includes the following steps: Step 1: Material Cutting: Precision cut the aluminum alloy profiles according to the dimensions specified in the design drawings. Cut the profiles into 21 sections of frame beams for the window frame and 22 sections of mullions. Use a double-headed cutting saw with a cutting angle of 45° or 90°, controlling the cutting accuracy within ±0.5mm. Simultaneously cut galvanized steel pipes for the first and second support strips 5 and 6. The length of the steel pipes must avoid the installation position of the window frame corner brackets, leaving a clearance of at least 50mm in the corner area. Cut galvanized steel sheets to form the bracket body 41 for reinforcing bracket 4, bending it according to the design dimensions.

[0053] Step 2, Milling and Grooving: Mill drainage grooves and hardware mounting holes on the aluminum alloy profile section. The drainage grooves are created on the inner wall of the lower frame of frame beam 21. Hardware mounting holes include handle holes, hinge mounting holes, and pin mounting holes. Pre-drill through holes or mill grooves on the cavity walls of the mullion beam 22 and frame beam 21 for heat conduction through the groove 73.

[0054] Step 3: Inserting the support strips: Insert the first support strips 5 into each support cavity 223 of the central beam 22, and secure them in place. If necessary, reinforce with self-tapping screws. Insert the second support strips 6 into each stable branch pipe 23 and secure them in place.

[0055] Step 4: Install the fireproof components for the central cavity: Install the heat-conducting bracket 7 and the second expansion strip 32 in the first central cavity 222 and the second central cavity 212. First, position the heat-conducting plate 71 of the heat-conducting bracket 7 into the slot on the inner wall of the central cavity, and adjust the orientation of the heat-conducting edge 73 so that it passes through the through hole or slot reserved in the profile. Then, push the second expansion strip 32 into the central cavity, align the heat-conducting support strip 72 with the snap-fit ​​groove 321 on one side of the second expansion strip 32, and insert it so that the mating protrusions 721 on the heat-conducting support strip 72 are embedded one by one into the connecting grooves 322 on the inner side wall of the snap-fit ​​groove 321, completing the multi-point snap-fit ​​connection. After confirming that the heat-conducting support strip 72 is firmly snapped in and the second expansion strip 32 is filled in place, install the first barrier strip 33 at the connection between the first connecting cavity 221 and the first central cavity 222, and install the second barrier strip 34 at the connection between the second connecting cavity 211 and the second central cavity 212.

[0056] Step 5, Corner Assembly: Place the 21 sections of multiple frame beams of the window frame into the corner assembly device, insert aluminum alloy corner brackets at each corner, and mechanically assemble the corners. After corner assembly, inject corner adhesive into the gaps to ensure the sealing and structural strength of the corners. After the corner adhesive cures, a solid overall window frame structure is formed.

[0057] Step Six: Install the Mullion: Install the mullion beam 22 inside the window frame. The end of the mullion beam 22 is positioned against the inner wall of the window frame using a mullion connector. Connecting screws are inserted from the outside of the profile and driven into the first support strip 5 inside the mullion beam 22, utilizing the threaded retention force of the steel pipe to achieve a secure connection. The intersection of the transverse and longitudinal mullion beams 22 is also fixed using screws. After installation, check the verticality and horizontality of the mullions.

[0058] Step 7: Install the fireproof components and glass in the connecting cavities: Install the reinforcing brackets 4 in each of the first connecting cavities 221 and the second connecting cavity 211, and fix the bracket body 41 to the inner wall of the first connecting cavity 221 or the second connecting cavity 211 with screws. Place the glass pad 42 on the bracket body 41. Attach or insert the first expansion strip 31 at an appropriate position on the inner wall of the first connecting cavity 221 or the second connecting cavity 211.

[0059] Then, the side of glass unit 1 is inserted into the first connecting cavity 221 or the second connecting cavity 211, and the bottom edge of glass unit 1 is placed on the glass pad 42. Fireproof cotton strips 35 are filled on both sides of the side of glass unit 1, so that the fireproof cotton strips 35 evenly and tightly fill the gap between the outer surface of the glass and the inner wall of the connecting cavity. Finally, sealant 36 is applied to the connection gap between glass unit 1 and the opening of the connecting cavity.

[0060] For fire-resistant windows containing sashes, there is also a step eight. Step eight: Install sealing strips and hardware: Install door and window sealing strips at the overlap between the window sash and the window frame. The door and window sealing strips are made of EPDM rubber. Install fire-resistant hardware accessories such as steel hinges, steel handles, and steel latches, and test the opening and closing functions and locking force.

[0061] Step 9, Inspection: The finished fire-resistant windows undergo visual inspection, dimensional inspection, airtightness test, and watertightness test. Only after confirming that all indicators meet the design requirements and relevant standards can they be shipped from the factory.

[0062] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
