[0002] A curtain wall is a non-load-bearing exterior enclosure structure typically consisting of panels and a supporting structure. Curtain walls not only provide decorative effects but also provide thermal insulation, waterproofing, and fire protection. With the development of the construction industry, curtain wall technology is also constantly innovating. With the rise of green and low-carbon buildings, the demand for energy-saving and low-carbon curtain wall materials is increasing.

[0003] Glass-fiber polyurethane is a new building material with excellent performance, gaining widespread application in the construction industry, particularly as the primary supporting structure for curtain walls. Existing glass-fiber polyurethane curtain wall beams have gained market recognition for their energy-saving and low-carbon properties.

The first beam 1 has a hollow cavity, the second beam 2 is arranged in the cavity of the first beam 1, the metal bracket 10 is installed on the first beam 1, and the metal bracket 10 is supported on the bottom of the glass body 7. The first beam 1 is made of polyurethane material, and the second beam 2 is made of metal material. As shown in the figure, the first beam 1 adopts a glass fiber reinforced polyurethane composite material, and a thin-walled cavity structure is formed by integrally molding the glass fiber polyurethane composite material. A thin-walled cavity metal beam is inserted into the cavity as the second beam 2 to enhance the structural strength, effectively improving the bending and tensile properties of the entire curtain wall structure, while also taking into account the characteristics of green, low carbon and energy saving.

[0021] In this embodiment, a fixed backing plate 11 and a metal sub-frame 3 are further included. The metal sub-frame 3 is mounted on the glass body 7. The fixed backing plate 11 is detachably mounted on the first crossbeam 1. The fixed backing plate 11 compresses the metal sub-frame 3 and restricts it to the first crossbeam 1. The metal sub-frame 3 is fixedly connected to the glass body 7 via an adhesive. As shown in the figure, in this embodiment, the metal sub-frames 3 are provided at both the upper and lower ends of the glass body 7. The metal sub-frames 3 are connected to the inner wall surface of the glass body 7 (i.e., the wall surface facing the building after installation) via structural adhesive 4. The curtain wall glass body 7 is provided in multiple pieces from bottom to top. The metal sub-frame 3 bonded to the lower portion of the glass body 7 and the metal sub-frame 3 bonded to the upper portion of the next glass body 7' are fixed to the first crossbeam 1 via the same fixed backing plate 11, as shown in the figure. The metal bracket 10 is supported on the bottom of the glass body 7. In this embodiment, the adhesive comprises structural adhesive 4 and sealant 5. The glass body 7 and metal sub-frame 3 are first connected using the structural adhesive 4, followed by a sealant 5, as shown in the figure.

The metal bracket 10 is fixed to the beam groove 14 of the first beam 1 by means of the tail hook. A pad 6 is also included. The front portion of the metal bracket 10 is supported on the bottom surface of the glass body 7. The pad 6 is provided between the glass body 7 and the metal bracket 10. As shown in the figure, in this embodiment, the end of the metal bracket 10 is directly engaged in the beam groove 14 through the tail hook. The front portion of the metal bracket 10 is supported by force on the glass body 7. Therefore, the rear portion of the metal bracket 10 is forced to tilt upward, and the tail hook is directly engaged and engaged with the upper portion of the interior of the beam groove 14, thereby ensuring support for the glass body 7. At the same time, in this embodiment, the fixed lining plate 11 is fixed to the first crossbeam 1 by a bolt assembly 12. As shown in the figure, the nut of the bolt assembly 12 is pre-embedded in the crossbeam groove 14. The bolt of the bolt assembly 12 passes through the fixed lining plate 11 and extends into the crossbeam groove 14 before being tightened with the nut. Then, the fixed lining plate 11 presses the metal sub-frame 3 to the first crossbeam 1. At the same time, to further limit the metal sub-frame 3 and the fixed lining plate 11, a "C"-shaped groove is provided on the front face of the first crossbeam 1 as shown in the figure. The fixed lining plate 11 in this embodiment has a "T"-shaped structure, which can simultaneously fix two metal sub-frames 3, making more reasonable space utilization. The provision of the spacer 6 can prevent the metal bracket 10 from directly contacting the glass body 7, providing a force buffering effect. In this embodiment, the metal bracket 10 and the bolt assembly 12 are staggered.

[0023] In this embodiment, the second crossbeam 2 is recessed inward to form a snap-fit ​​groove, which is snap-fitted to the crossbeam groove 14. In this embodiment, the outer surface of the second crossbeam 2 is provided with a plurality of limiting protrusions, which abut against the inner wall surface of the first crossbeam 1. In this embodiment, the second crossbeam 2 has a "concave"-shaped structure. From the overall structure, the second crossbeam 2 can be snap-fitted into the first crossbeam 1, and combined with the plurality of limiting protrusions, the first crossbeam 1 and the second crossbeam 2 are fixed and connected without the need for an additional connecting structure. The second crossbeam 2 is embedded in the first crossbeam 1 by snapping, forming a single crossbeam.

[0024] This embodiment also includes curtain wall columns and connectors 13. The inner wall surface of the second crossbeam 2 is provided with fixing holes 15. The connectors 13 are inserted into the fixing holes 15, and the second crossbeam 2 is connected to the curtain wall columns through the connectors 13. As shown in the figure, the fixing holes 15 are "C"-shaped latch holes, and there are three of them. The connectors 13 are spring latches, and the first crossbeam 1 and the second crossbeam 2 are connected to the curtain wall columns via the spring latches.
