The U-shaped glass components 3 include two oppositely arranged U-shaped glasses 31. The notches of the U-shaped glasses 31 are opposite to each other. The two U-shaped glasses 31 are connected and fixed by two sets of connecting parts 5 to form a whole. This greatly increases the overall structural rigidity of the U-shaped glass and can solve the problem of large-span layout of U-shaped glass curtain walls. The upper and lower ends of the beam 2 are respectively provided with grooves 21 for accommodating the U-shaped glass components 3. The U-shaped glass components 3 are placed in the grooves 21. The grooves 21 are provided with fastening screws 6 for pressing the upper or lower end of the U-shaped glass components 3.

[0021] In the present invention, the span varies according to different wind pressure areas; the span of the U-shaped glass 31 can be set to more than 8m, and the span of the U-shaped glass 31 in typhoon-prone areas can exceed 5m.
