The metal profiles 1 are arranged side by side, and two metal profiles 1 are connected by a sealing insulation strip 4. The sealing insulation strip 4 is a pa66 insulation strip, that is, a polyamide (nylon) insulation strip, wherein an insulation cavity A2 is formed between the sealing insulation strip 4 and the wall panels of the two metal profiles 1, and an insulation cavity B3 is provided in the metal profile 1, so that air conduction replaces metal conduction, thereby reducing the transfer of indoor and outdoor heat.

[0025] Reinforcing ribs 6 are fixedly connected between the inner walls of the insulation cavity A2. Without increasing the wall thickness of the metal profile 1, the strength and rigidity of the metal profile 1 can be improved by adding the reinforcing ribs 6, thereby significantly improving its bearing capacity. On the basis of saving material usage and reducing costs, the overall stability and wind pressure resistance of the doors and windows are improved. The side walls of the reinforcing ribs 6 are penetrated by dividing grooves 7, which can further reduce the transfer of indoor and outdoor heat.

[0026] A sealing component is provided at one end of the metal profile 1 to further enhance the thermal insulation effect and reduce heat conduction. A cavity for placing glass is formed between the two sealing components. When the glass is inserted into the cavity, one end of the glass is against the sealing insulation strip 4. The sealing insulation strip 4 serves as an isolation layer for heat transfer between the door and window frames and the glass, reducing the exchange of indoor and outdoor temperatures, achieving the effect of thermal insulation, and increasing the sealing of doors and windows.

[0027] Specifically, the sealing assembly includes a closed decorative buckle strip 51 and a clamping member 52 which are respectively arranged on both sides of the cavity. By providing the closed decorative buckle strip 51, the glass can be fixed, protected and decorated.

[0028] One side of the closed decorative buckle strip 51 is against the glass, which is stronger than the open buckle strip, increasing the stability of the doors and windows, while preventing the doors and windows from deforming, enhancing the supporting force of the doors and windows, and improving the overall quality of the doors and windows. It can also effectively prevent the entry of water, wind, dust and other substances, and increase the sealing of the doors and windows. The clip 52 is clipped to the closed decorative buckle strip 51, and the clip 52 is used to install the closed decorative buckle strip 51.

[0029] Specifically, the closed decorative buckle strip 51 includes a buckle strip frame 511, and a sealing pressure plate 512 is fixedly connected to the outer wall of the buckle strip frame 511 close to the cavity side. The sealing pressure plate 512 abuts against the side of the glass inserted in the cavity to ensure that the closed decorative buckle strip 51 can firmly fix the glass to prevent it from moving or falling off. An avoidance arc 513 is provided at the bottom of the sealing pressure plate 512. When installing the glass, it is necessary to apply glue to the edge of the glass. The avoidance arc 513 can prevent damage to the solidified colloid.

[0030] Specifically, the clamping member 52 is two clamping plates 521 arranged opposite to each other, and the clamping plates 521 are fixedly connected to the metal profile 1. The clamping plates 521 are used to install the closed decorative buckle strip 51. A slot 522 is formed between the clamping plates 521 close to the side of the cavity and the metal profile 1. The closed decorative buckle strip 51 includes a buckle strip frame 511, and an insert plate 514 is fixedly connected to the outer wall of the buckle strip frame 511. When installing the closed decorative buckle strip 51, it is necessary to first insert the insert plate 514 into the slot 522 to clamp the closed decorative buckle strip 51.

[0031] Specifically, a blocking arc 523 is provided on the clamping plate 521 on the side away from the cavity, and a limiting arc 515 is provided on the outer wall of the buckle strip frame 511 on the side away from the cavity. The limiting arc 515 is consistent with the shape of the blocking arc 523. When the closed decorative buckle strip 51 is installed, the limiting arc 515 is in contact with the blocking arc 523 to ensure the sealing of doors and windows.
