The corner column 1 is located at the corner of the broken-line curtain wall. The corner column 1 and the transition column 2 are fixedly connected, and the transition column 2 is fixedly connected to the building main body, forming a support keel system at the corner position of the broken-line curtain wall.

[0024] The wing keel includes a wing cross beam 4, a wing column 5, and a wing bracket 6. The inner sides of the wing cross beam 4 and the wing column 5 are fixedly connected to the wing bracket 6. The wing bracket 6 is fixedly connected to the corner column 1 and the transition column 2. Specifically, the wing bracket 6 is connected to the corner column 1 and the transition column 2 by M10 stainless steel bolts 8. The wing cross beam 4 and the wing column 5 are both fixedly connected to the wing bracket 6 by M8 stainless steel bolts 9. And sealant 10 is applied at the joints between the wing cross beam 4 and the wing bracket 6 and between the wing column 5 and the wing bracket 6 to ensure the sealing effect between the wing cross beam 4 and the wing bracket 6 and between the wing column 5 and the wing bracket 6.

[0025] In this embodiment, the cross-sectional width of the wing bracket 6 decreases from the side close to the corner column 1 to the side far from the corner column 1, forming a tapered wing bracket 6 to adapt to the load distribution of the broken-line curtain wall.

The power generation glass 3 is fixedly installed on the outer side of the planar frame. Specifically, the wing cross beam 4 and the wing column 5 are fixed by self-tapping screws. One end of the power generation glass 3 close to the corner column 1 is fixed on the wing column 5 by weather-resistant sealant 16, thus forming a single-side borderless wing glass structure, that is, one side of the power generation glass 3 uses the weather-resistant sealant 16 as the border and is exposed without a border on the outside, so as to meet the requirements of curtain wall shading while ensuring structural safety and also meeting the requirements of building aesthetic functions.

[0027] In this embodiment, the power generation glass 3 is a cadmium telluride power generation glass. A photovoltaic groove 7 is provided on the wing column 5. One end of the power generation glass 3 close to the corner column 1 cooperates with the photovoltaic groove 7.

One end of the photovoltaic outer cover plate 11 is clamped on the outer side of the flying wing column 5 and fixed by self-tapping screws. The other end of the photovoltaic outer cover plate 11 presses against the outer side of the end of the power generation glass 3, and a structural adhesive 12 is provided at the contact position between the photovoltaic outer cover plate 11 and the power generation glass 3. By pressing the power generation glass 3 from the outside by the photovoltaic outer cover plate 11, the structural stability of the power generation glass 3 is improved. At the same time, the structural adhesive 12 is provided at the contact position between the photovoltaic outer cover plate 11 and the power generation glass 3 to prevent rainwater or dust from entering the inside of the photovoltaic outer cover plate 11, effectively ensuring the sealing effect of the connection.

[0029] By designing the cadmium telluride power generation glass 3 as the panel of the curtain wall flying wing, not only can the curtain wall generate electricity, effectively saving energy and conforming to the trend of sustainable development, but also the sunshade function of the curtain wall can be realized, greatly enhancing the aesthetic appearance of the curtain wall.

[0030] An aluminum alloy edge guard 13 is provided at the cantilever end of the power generation glass 3, and the aluminum alloy edge guard 13 is connected and fixed to the flying wing cross beam 4; the aluminum alloy edge guard 13 is U-shaped, and the power generation glass 3 is embedded in the U-shaped groove of the aluminum alloy edge guard 13 to protect the cantilever end of the power generation glass 3 and prevent the cantilever end of the power generation glass 3 from being exposed to the external environment.

[0031] As a preferred embodiment, a flexible cushion block 14 is provided in the U-shaped groove bottom of the aluminum alloy edge guard 13. The flexible cushion block 14 is fixed on the aluminum alloy edge guard 13 by a pin 15. The aluminum alloy edge guard 13 cooperates with the cantilever end of the power generation glass 3 through the flexible cushion block 14. In this embodiment, the flexible cushion block 14 is made of EPDM rubber. Of course, flexible materials commonly used in the art such as rubber strips can also be used to avoid local stress concentration or cracking caused by direct contact between the power generation glass 3 and the aluminum alloy edge guard 13.
