[0031] The large-span glass curtain wall structure provided in the embodiment of the present application uses a steel pipe 110, two aluminum cover plates 120 wrapped on both sides of the steel pipe 110, a cover seam plate 130 and an aluminum joint 140 to form a vertical keel 100, and uses a horizontal keel 200 located on both sides of the vertical keel 100 and playing a horizontal supporting role for the vertical keel 100 to form a grid structure to support the two glass panels 300 as a whole. The pressure cover structure 400 connected with the vertical keel 100 is used to press and fix the glass panel 300, which can effectively improve the safety performance of the large-span structure.

[0032] Among them, the vertical keel 100 adopts the steel pipe 110 as the main load-bearing component, which has the advantages of high strength, good structural safety performance and low cost compared with the aluminum alloy keel, and uses an aluminum cover plate 120 to wrap the outside of the steel pipe 110, which can not only prevent the steel pipe 110 from rusting and improve the durability of the steel pipe 110, but also improve the decorative effect of the vertical keel 100.

The cover seam plate 130 is arranged in the cover slot 122 and is connected to the steel pipe 110 by a third bolt 131. The cover seam plate 130 and the third bolt 131 can be used to press the two aluminum cover plates 120 to the inside of the steel pipe 110.
