Description

Technical Field

[0001] This utility model relates to the field of glass window technology, specifically a multi-cavity heat-insulating and fireproof glass window. Background Technology

[0002] Fire-resistant glass windows are special building components that can maintain their integrity and thermal insulation under specified fire resistance test conditions. In the event of a fire, they effectively block the penetration of flames, high-temperature smoke, and heat for a certain period of time, buying time for the safe evacuation of people, preventing the spread of fire, and protecting property. With the increasing demands for both safety performance and light transmission in modern buildings, fire-resistant glass windows have become a key safety guarantee facility for high-rise buildings, large public venues, and important facilities.

[0003] Insulated fireproof glass windows mainly rely on the material properties of the single fireproof glass or composite layer itself. When faced with prolonged or high-intensity fire heat attack, the heat transfer path is single, the thermal resistance is limited, and the temperature rises faster on the unexposed side, making it difficult to meet higher fire resistance requirements. The temperature difference between the fire-facing and unexposed sides of the glass is large, forming extremely high thermal stress, which can easily cause the glass to crack or soften and deform. Utility Model Content

[0004] The purpose of this invention is to provide a multi-cavity heat-insulating and fire-resistant glass window to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A multi-cavity insulated and fireproof glass window, including a window frame, and further comprising: The window frame has a sliding groove inside, and a support frame is set inside the sliding groove. The support frame is formed by two square plates being glued together. The support frame has an installation groove for installing fireproof glass inside, and a glass plate is set inside the installation groove. The window frame, the support frame, and the glass plate constitute the glass window body. A main heat insulation cavity is formed between the two glass plates. The heat insulation board has a square groove inside the support frame. Louvers are vertically arranged inside the square groove. A pivot is arranged between two adjacent louvers. Multiple louvers are connected to each other through the pivot and are slidably arranged inside the support frame. Heat insulation boards are arranged on the louvers. The louvers slide along the inner wall of the square groove. Multiple heat insulation boards move to a parallel position and divide the main heat insulation cavity into multiple secondary heat insulation cavities. A fixed block and a movable block are arranged on the top of the louvers. The fixed block is fixedly arranged inside the square groove. The drive mechanism, connected to the movable block, can drive multiple louvers to slide along the square groove.

[0006] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative embodiment: the driving mechanism includes a movable plate, a transmission plate, and a driving rod. The movable plate and the driving rod are disposed inside the square groove. A fixed box is disposed inside the square groove. A torsion spring connected to the driving rod is disposed inside the fixed box. The movable plate is connected to a movable block. A transmission plate is disposed on the side wall of the movable plate. A rack is disposed on the side of the two transmission plates that are close to each other. A gear that meshes with the rack is disposed on the outside of the driving rod.

[0007] In one alternative: a piston plate is provided inside the fixing box, and a thermal expansion medium is filled between the piston plate and the inner wall of the fixing box. A pressure plate is provided on the side wall of the piston plate, and a groove is provided inside the pressure plate. A fixing pin that cooperates with the drive rod is provided inside the groove.

[0008] In one alternative: the side wall of the movable plate is provided with a guide groove, and the movable block is slidably disposed inside the guide groove.

[0009] In one alternative: a return spring is provided inside the fixing box, and one end of the return spring is connected to the piston plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: Multi-cavity insulated fireproof glass windows consist of a window frame, a support frame, and glass panels. The thermal expansion medium inside the fixing box expands when heated and pushes the piston plate to move, causing the fixing pin to disengage from the drive rod. The drive rod, through the meshing of gears and racks, drives the movable plate and louvers to slide out and unfold from the square groove. The fully unfolded louvers and their heat insulation plates divide the main heat insulation cavity into multiple independent secondary heat insulation cavities, forming multiple thermal barriers, suppressing air convection and reflecting heat radiation, thus improving heat insulation performance. The unfolded louver structure forms an internal support skeleton between the two layers of glass panels, enhancing the overall stability of the window. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. In the drawings and description, similar or identical parts are referred to by the same reference numerals, and in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this utility model are merely illustrative and not intended to limit the scope of this utility model. Any obvious modifications or changes made to this utility model do not depart from its spirit and scope.

[0020] In one embodiment, such as Figures 1-7 As shown, a multi-cavity insulated fireproof glass window includes a window frame 1, and further includes: The support frame 2 has a sliding groove 101 inside the window frame 1, and the support frame 2 is installed inside the sliding groove 101. The support frame 2 is formed by two square plates being bonded together. During window maintenance, the entire support frame 2 and its internal components can be pulled out from the sliding groove 101, facilitating quick disassembly, replacement, or repair of internal components such as the louvers 4 and drive mechanism, thus improving product maintainability. The support frame 2 also has an installation groove 202 for installing fireproof glass. Glass panel 3 is a heat-insulating fireproof glass, which is composed of two or more layers of glass sheets. It blocks the heat radiation and heat conduction of flames. The window frame 1, the support frame 2 and the glass panel 3 constitute the glass window body. The two glass panels 3 form a main heat insulation cavity. The main heat insulation cavity can form an effective static heat barrier. The internal air layer has a low thermal conductivity, which can delay heat transfer. The two layers of glass form a double radiation barrier, which disperses the temperature difference between the fire-facing side and the unfacing side on the two layers of glass, preventing the single glass from breaking quickly due to thermal stress. The heat insulation plate 9 has a square groove 201 inside the support frame 2. Multiple louvers 4 are hinged to each other through a pivot to form a foldable louver structure and are slidably set in the square groove 201. Each louver 4 is fixedly connected to a heat insulation plate 9. The heat insulation plate 9 is made of a polished stainless steel sheet or a metal sheet coated with a high reflectivity ceramic coating. It has good stability at high temperatures and can effectively reflect infrared heat radiation, thus providing better heat insulation performance inside the cavity. The louvers 4 slide along the inner wall of the square groove 201. Multiple heat insulation plates 9 move to a parallel position and divide the main heat insulation cavity into multiple secondary heat insulation cavities. Multiple parallel heat insulation plates 9 divide the original main heat insulation cavity into multiple parallel and independent secondary heat insulation cavities, suppressing the efficiency of air convection heat transfer. Each heat insulation plate 9 has a heat radiation reflective surface to form a heat insulation structure. The unfolded louvers 4 and heat insulation plates 9 form a grid-like support frame between the two layers of glass 3, which enhances the overall structural stability of the window at high temperatures. The drive mechanism, connected to the movable block 10, can drive multiple louvers 4 to slide along the square groove 201.

[0021] In one embodiment, such as Figures 1-7 As shown, the driving mechanism includes a movable plate 11, a transmission plate 7, and a driving rod 6. The movable plate 11 and the driving rod 6 are arranged inside the square groove 201. A fixed box 5 is arranged inside the square groove 201. A torsion spring connected to the driving rod 6 is arranged inside the fixed box 5. The movable plate 11 is connected to the movable block 10. A transmission plate 7 is arranged on the side wall of the movable plate 11. A rack 8 is arranged on the side of the two transmission plates 7 that are close to each other. A gear 12 that meshes with the rack 8 is arranged on the outside of the driving rod 6. When the driving rod 6 is triggered to rotate, it can drive the gear 12 to rotate. The gear 12 drives the transmission plate 7 to move by meshing with the racks 8 on both sides. The transmission plate 7 drives the movable plate 11 and the movable block 10 to move, thereby driving the louver structure to slide out of the square groove 201. The hinged louver 4 gradually unfolds during the sliding process, and finally all the louver 4 and its heat insulation plate 9 move into the main heat insulation cavity and fully unfold, dividing the main heat insulation cavity into multiple secondary heat insulation cavities.

[0022] In one embodiment, such as Figures 1-7As shown, a piston plate 14 is provided inside the fixed box 5. The space between the piston plate 14 and the inner wall of the fixed box 5 is filled with a thermal expansion medium. A pressure plate 15 is provided on the side wall of the piston plate 14. A groove 17 is provided inside the pressure plate 15. A fixing pin 18 that cooperates with the drive rod 6 is provided inside the groove 17. When a fire occurs, the ambient temperature rises to a predetermined threshold. The thermal expansion medium in the fixed box 5 expands in volume due to heat, pushing the piston plate 14 and the pressure plate 15 to move to one side. The movement of the pressure plate 15 causes the groove 17 to move accordingly. The fixing pin 18 inserted into the drive rod 6 moves and disengages from the drive rod 6, releasing the rotation lock on the drive rod 6. The pre-stored torsion spring quickly releases its elastic potential energy, and the drive rod 6 rotates. Then, through the aforementioned gear and rack transmission mechanism, the louvers 4 are driven to unfold rapidly.

[0023] In one embodiment, such as Figure 5 As shown, the movable plate 11 has a guide groove 13 on its side wall, and the movable block 10 is slidably disposed inside the guide groove 13, ensuring that the movable plate 11 can slide horizontally.

[0024] In one embodiment, such as Figure 7 As shown, a reset spring 16 is provided inside the fixed box 5, and one end of the reset spring 16 is connected to the piston plate 14.

[0025] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
