Description

Technical Field

[0001] The utility model relates to the technical field of fireproof aluminum alloy doors and windows, in particular to a fireproof aluminum alloy door and window with a sealing structure. Background Art

[0002] Fireproof aluminum alloy doors and windows are made of aluminum alloy materials and have excellent fireproof performance. They are usually made of high-strength aluminum alloy profiles to form door and window frames, and are equipped with fireproof glass and special fireproof sealing materials. These doors and windows can effectively isolate flames and high temperatures in a fire, slowing the spread of fire and buying valuable time for personnel evacuation and fire rescue. Fireproof aluminum alloy doors and windows not only have good fire resistance time (such as 30 minutes to 2 hours), but also have excellent high temperature resistance and stability. They can maintain structural integrity even in high temperature environments. In addition, they also have good sound insulation performance and beautiful appearance, which can meet the needs of different building scenarios. In commercial complexes, hospitals, schools and other places with high personnel density and high safety requirements, fireproof aluminum alloy doors and windows play a vital role.

[0003] Although the existing technology has met the users' needs to a certain extent, there are still certain defects in the use process. The specific problems are as follows: Although the existing fire-proof aluminum alloy doors and windows have a certain sealing effect when in use, if the sealing effect is not good, it will significantly affect its comprehensive performance. First, poor sealing will lead to energy waste, because the indoor and outdoor air exchange increases, which reduces the thermal insulation effect and increases the energy consumption of the air conditioning or heating system. Secondly, the sound insulation performance will also be greatly reduced, and external noise can more easily penetrate the doors and windows, affecting the tranquility of the indoor environment. Moreover, poor sealing may also cause rainwater leakage, damage interior decoration and furniture, and even affect the health of residents. Most importantly, in emergency situations such as fire, insufficient sealing will accelerate the spread of smoke and toxic gases, which will have an adverse effect on the evacuation and rescue of personnel.

[0004] In order to solve the above problems, we have made improvements and proposed a fire-proof aluminum alloy door and window with a sealed structure. Utility Model Content

[0022] See also Figure 1-6 A fireproof aluminum alloy door and window with a sealed structure includes a frame 1, the front and back sides of the inner cavity of the frame 1 are fixedly connected to the glass body 2, the left and right sides of the inner cavity of the frame 1 and the inner side of the glass body 2 are bonded with a sealing strip 5, the top of the inner cavity of the frame 1 is movably connected to a screw 6 through a bearing, the left and right sides of the surface of the screw 6 are threadedly connected to a screw sleeve 7, the bottom of the screw sleeve 7 is fixedly connected to a connecting rod 8, the outer side of the connecting rod 8 is fixedly connected to a pressure plate 3, the outer side of the pressure plate 3 is in contact with the inner wall of the sealing strip 5, and the left side of the top of the inner wall of the frame 1 is in contact with the inner wall of the frame 1. There are slide grooves 9 on both sides of the right side. The top of the screw sleeve 7 is fixedly connected to the slider 10. The top of the slider 10 is slidably connected to the inner cavity of the slide groove 9. The middle end of the surface of the screw 6 is fixedly connected to the driven gear 11. The top of the inner cavity of the frame 1 and the front side of the driven gear 11 are movably connected to the driving gear 12. The driven gear 11 and the driving gear 12 are engaged with each other through teeth. The top of the front surface of the frame 1 is movably connected to the handwheel 4 for driving the driving gear 12 to rotate. The back side of the handwheel 4 is fixedly connected to the middle end of the front surface of the driving gear 12.

[0023] According to the above technical solution, the screw 6 uses the action of the opposing threads to simultaneously drive the screw sleeves 7 on both sides to move outward during the rotation process, the screw sleeves 7 drive the connecting rods 8 to move outward, and the connecting rods 8 drive the pressure plate 3 to move outward. The sealing strip 5 is squeezed by the pressure plate 3, so that the sealing strip 5 produces a certain expansion and deformation and fits tightly in the inner cavity of the frame 1, thereby improving the sealing effect of the sealing strip 5 and effectively preventing the penetration of air, moisture and noise. By providing the slider 10 and the slide groove 9, the stability of the connecting rod 8 during horizontal movement can be effectively improved. By setting the number of glass bodies 2 to two, the inner cavity of the frame 1 can be formed into a hollow cavity, which reduces the transfer of heat between indoor and outdoor, helps to maintain the stability of indoor temperature and reduce energy consumption. Secondly, the hollow layer can be filled with inert gas such as argon or installed with special thermal insulation materials to further enhance the thermal insulation effect and improve living comfort. In addition, it also has good sound insulation performance, can effectively isolate external noise and create a quiet indoor environment. At the same time, this design also enhances the overall stability and safety and improves the durability of the overall structure.

[0024] Specifically, the sealing strip 5 includes a fluorocarbon coating 501, a polyvinyl chloride material layer 502, an EPDM rubber layer 503 and a polyurethane foam material layer 504. The EPDM rubber layer 503 is arranged on the outside of the polyurethane foam material layer 504, the polyvinyl chloride material layer 502 is arranged on the outside of the EPDM rubber layer 503, and the fluorocarbon coating 501 is applied on the outside of the polyvinyl chloride material layer 502. The thickness of the polyvinyl chloride material layer 502 is the same as that of the EPDM rubber layer 503, and the thickness of the polyvinyl chloride material layer 502 and the thickness of the EPDM rubber layer 503 are both 5mm-7mm.

[0025] Through the above technical solution, the polyurethane foam material layer 504 has excellent compressibility and resilience, effectively preventing the penetration of air and water, and at the same time can absorb and isolate the transfer of sound and heat, thereby improving the overall sound insulation and heat insulation performance. The EPDM rubber layer 503 has excellent weather resistance, and can resist the erosion of environmental factors such as ultraviolet rays and ozone, and maintain long-term stable sealing performance. The polyvinyl chloride material layer 502 has good corrosion resistance, and can resist the erosion of chemical substances such as acids and alkalis, thereby enhancing the overall structural strength of the sealing strip 5. The fluorocarbon coating 501 can further improve the weather resistance of the sealing strip 5, resist the erosion of environmental factors such as ultraviolet rays and rain, and extend the service life of the sealing strip 5. Through the coordinated use of the fluorocarbon coating 501, the polyvinyl chloride material layer 502, the EPDM rubber layer 503 and the polyurethane foam material layer 504, the sealing performance of the sealing strip 5 can be significantly improved, while its service life is extended and the appearance is beautified, thereby meeting the sealing requirements under different environments and conditions.

[0026] When in use, first apply high-quality sealant between the frame 1 and the wall to effectively fill the gap and enhance the sealing effect. After the overall installation is completed, turn the handwheel 4, and the handwheel 4 drives the active gear 12 to rotate. The active gear 12 drives the driven gear 11 to rotate by the action of tooth meshing, and the driven gear 11 drives the screw 6 to rotate. During the rotation process, the screw 6 uses the action of the opposing threads to simultaneously drive the screw sleeves 7 on both sides to move outward, and the screw sleeves 7 drive the connecting rod 8 to move outward. The connecting rod 8 drives the pressure plate 3 to move outward, and the sealing strip 5 is squeezed by the pressure plate 3, so that the sealing strip 5 produces a certain expansion and deformation and fits tightly in the inner cavity of the frame 1, thereby improving the sealing effect of the sealing strip 5 and effectively preventing the penetration of air, moisture and noise. During the sealing process of the sealing strip 5, the polyurethane foam material layer 504 has excellent compressibility and resilience, which effectively prevents the penetration of air and water, and can absorb and isolate sound and heat.
