[0001] The utility model relates to the technical field of building profiles, in particular to a building door and window structure. Background Art

[0002] Traditional building doors and windows often use metal materials, such as aluminum alloy, to construct window and door frames. Although metal materials have certain strength and durability, due to the high thermal conductivity of metal itself, the door and window components become a bridge for heat conduction, thereby reducing the thermal insulation performance of the building. This will lead to the conduction and convection of temperature inside and outside the building, increase the loss of cold and heat energy, increase energy consumption, and reduce indoor comfort.

[0003] With the increasing requirements for energy conservation and environmental protection, the demand for thermal insulation performance of building doors and windows is becoming increasingly urgent. In order to improve the thermal insulation performance of doors and windows, some solutions have been proposed, such as reducing heat conduction and improving the thermal insulation performance of doors and windows by setting a thermal break in aluminum alloy profiles. However, traditional thermal break aluminum alloy doors and windows still have some problems, such as structural instability, poor thermal insulation performance, and corrosion resistance. Therefore, those skilled in the art have proposed a building door and window structure to solve the above problems. Summary of the invention

[0027] The thermally-insulated aluminum profile 6 includes two aluminum alloy connecting parts 12 , the inner sides of the two aluminum alloy connecting parts 12 are filled with a heat-insulating material 14 , and the outer surfaces of the aluminum alloy connecting parts 12 are provided with a PVC micro-foam heat-insulating layer.

[0028] Specifically, the aluminum alloy connecting parts 12 have excellent strength and corrosion resistance and are used to form the main structure of the doors and windows. They provide stable support and structural strength for the doors and windows, ensuring the stability and safety of the doors and windows.

[0029] The function of the thermal insulation material 14 is to reduce the conduction of heat and improve the thermal insulation performance of doors and windows. The thermal insulation material 14 filled inside the aluminum alloy connection 12 profile can block the formation of thermal bridges and reduce the transmission of heat in doors and windows, thereby effectively reducing energy loss.

[0030] The PVC micro-foam insulation layer is located on the outer surface of the aluminum alloy connection part 12 profile. It is made by micro-foaming the PVC material, which has a lower thermal conductivity and better thermal insulation performance. This insulation layer further enhances the thermal insulation performance of the doors and windows and reduces the conduction of heat. At the same time, the PVC material also has excellent weather resistance and corrosion resistance, which improves the durability and service life of the doors and windows.

[0032] Specifically, the multi-cavity sealing strip 11 is used to provide sealing performance and sound insulation effect for doors and windows. It is fixed inside the C-shaped groove 9 to form a continuous sealing strip, filling the gap on one side of the casement stile 1, and the structural design of the multi-cavity sealing strip 11 can effectively block the propagation of sound waves. It can reduce the intrusion of outdoor noise, provide a better indoor quiet environment, and enhance the sound insulation effect of doors and windows.

[0033] Please refer to the attached Figure 4 The outside of the casement frame 2 is equipped with an inward opening window sash bracket 3, the inner side of the casement frame 2 is fixedly connected with a multi-cavity sealing strip 17, and the inside of the casement frame 2 is filled with a sound insulation material 8, and the sound insulation material 8 and the heat preservation material 14 are both hard polyurethane foam materials.

[0034] Specifically, the inward opening window sash support 3 is installed on the outside of the casement frame 2 to support and fix the inward opening window sash. It provides a stable structural support so that the inward opening window sash can be opened and closed smoothly. The multi-cavity sealing strip 17 is fixedly connected to the inner side of the casement frame 2 to provide sealing performance for doors and windows. It fills the gap between the casement frame 2 and the window sash to prevent air, moisture, dust and other foreign substances from entering the room, keeping the room dry and clean;

[0035] The sound insulation material 8 is filled in the casement frame 2 to provide a sound insulation effect, which can effectively block the propagation of sound waves, reduce the intrusion of outdoor noise, and create a quieter indoor environment.

[0036] Please refer to the attached Figure 4 A third dovetail groove 16 is provided on one side of the exterior of the inward-opening window sash bracket 3 , and a sash strip 4 is mounted on the inner wall of the third dovetail groove 16 .

[0037] Specifically, the fan strip 4 is closely attached to the inner wall of the third dovetail groove 16 to form a sealed gap, which can effectively prevent foreign substances such as air, moisture and dust from entering the interior of the door and window, and keep the room dry and clean.

[0038] Please refer to the attached Figure 3 A first dovetail groove 13 is provided on one outer side of the casement stile 1, and a stile pressure strip 5 is slidably connected to the inner wall of the first dovetail groove 13.

[0039] Specifically, the muntin strip 5 is slidably connected to the inner wall of the first dovetail groove 13, firmly fixing the casement muntin 1 and the window frame together. It provides a stable connection, so that the casement muntin 1 can be smoothly opened and closed while maintaining good structural stability, and the design of the muntin strip 5 enables it to provide support for the casement muntin 1. It can withstand a certain pressure and load, ensuring that the casement muntin 1 remains stable and strong during use.

[0040] Please refer to the attached Figure 2 A second dovetail groove 15 is provided on the outside of the thermally-broken aluminum profile 6 , and a thermally-broken pressure strip 7 is installed inside the second dovetail groove 15 .

[0041] Specifically, the second dovetail groove 15 is a groove on the outside of the thermally-broken aluminum profile 6. It is located on one side or the bottom of the profile and is used to connect or fix other components. The design of the second dovetail groove 15 allows it to fit closely with other accessories to form a reliable connection while maintaining the structural stability of the window frame. The thermally-broken strip 7 is a component assembled inside the second dovetail groove 15. It is made of rubber or plastic material and has soft and durable characteristics. The function of the thermally-broken strip 7 is to provide sealing and heat insulation functions. When the window is closed, the thermally-broken strip 7 will be in close contact with the window frame, fill the window gap, and prevent foreign substances such as air, moisture and noise from entering the room. In addition, the thermally-broken strip 7 can also effectively isolate the conduction of cold and heat and improve the thermal insulation performance of the window.

[0042] Please refer to the attached Figure 3 A drainage groove 10 is provided on the outer surface of the casement middle stile 1, and the casement middle stile 1 is made of a plastic profile.

[0043] Specifically, the gutter 10 is a channel on the outer surface of the casement stile 1 for draining rainwater or other liquids. It has a certain inclination to ensure that water can flow out smoothly without accumulating inside the window frame. The gutter 10 helps prevent moisture from penetrating into the window frame, keeping the window dry and preventing water damage.

[0044] Plastic profiles are widely used in window frame manufacturing because of their advantages such as light weight, durability, heat insulation, insulation and easy processing. Plastic profiles can also be customized according to needs to adapt to window designs of different shapes and sizes. In addition, plastic profiles also have good waterproof properties, which can effectively prevent moisture from penetrating into the interior of the window frame.

[0045] A method for using a building door and window structure comprises the following steps:

[0046] S1, first produce the broken bridge aluminum profile 6, then pass the broken bridge aluminum profile 6 through the feeding port of the plastic twin-screw basic machine, and then the plastic powder or particles attached to the surface of the aluminum profile are melted by the rotation and heating of the screw, and then the molten plastic is mixed with the aluminum profile and extruded through a mold to form the shape of an aluminum-plastic co-extruded profile;

[0047] Specifically, aluminum-plastic co-extrusion profiles combine the advantages of aluminum and plastic. Aluminum has good strength and rigidity, while plastic has good weather resistance, heat insulation and sealing. By combining the two, better comprehensive performance can be obtained, and plastic has good elasticity and plasticity, which can fill the irregular parts of the aluminum profile surface and improve the sealing performance of the window frame. Through the aluminum-plastic co-extrusion process, plastic and aluminum profiles are closely combined, which can effectively prevent external substances such as air, moisture and noise from entering the room.

[0048] S2. After applying epoxy glue on the outer surface of the broken bridge aluminum profile 6, a layer of plastic profile is wrapped on its outer surface to prevent it from falling off and improve its acid, alkali and corrosion resistance;

[0049] S3, then connect the inward opening window sash bracket 3 and the flat opening middle stile 1, connect the flat opening middle stile 1 and the thermally-insulated aluminum profile 6, and fill the interior of the thermally-insulated aluminum profile 6 with a hard polyurethane foam material, thereby effectively isolating the external temperature conduction and improving the thermal insulation performance of the doors and windows;

[0050] S4. A C-shaped groove 9 is provided inside the casement stile 1 to facilitate the use of hardware on the market. At the same time, a drainage groove 10 is provided outside the casement stile 1 to play a waterproof role, thereby preventing rainwater from penetrating into the interior of doors and windows, and preventing water from causing deformation, corrosion or damage to doors and windows.

[0051] In summary, the utility model enhances the corrosion resistance and acid-base resistance of the aluminum profile by applying epoxy glue on the outer surface of the aluminum alloy connecting part 12 and wrapping a layer of plastic profile. This enables the doors and windows to resist the erosion of the external environment such as acid rain and salt corrosion, and prolongs their service life. At the same time, the hard polyurethane foam material is filled inside the broken bridge aluminum profile 6 to effectively isolate the temperature conduction from the outside and improve the thermal insulation performance of the doors and windows. This can reduce the transfer of heat, keep the indoor temperature stable, reduce energy consumption, and provide a more comfortable indoor environment.

[0052] Finally, the heat-insulating aluminum-plastic co-extruded profile uses a thermally broken aluminum profile 6 and is filled with hard polyurethane foam material in the door and window structure to effectively isolate the temperature conduction from the outside, reduce heat loss and heat exchange. It can reduce the frequency of use and energy consumption of indoor air conditioning or heating systems, thereby saving energy. At the same time, the heat-insulating aluminum-plastic co-extruded profile separates the indoor and outdoor aluminum materials through the design of the thermally broken aluminum profile 6, reducing the formation of thermal bridges and further reducing energy losses.
