[0001] The invention relates to the technical field of assembled wall panels, in particular to a large-span glass rib supporting curtain wall system and an installation process thereof. Background Art

[0002] Glass curtain wall refers to the building's external protective structure or decorative structure that has a certain displacement capacity relative to the main structure and does not share the effects on the main structure. Glass curtain wall is a beautiful and novel building wall decoration method, and is a prominent feature of the modernist high-rise building era. Large-span glass rib curtain wall: The building is no longer surrounded by four walls with windows on top. Modern buildings are full of modern characteristics and a sense of future technology.

[0003] Domestic curtain wall development history: ① 1980s-1990s: pioneering stage (simple curtain wall system); ② The first decade of the 21st century: development stage; ③ 2010s-2020s: glass curtain walls are widely used, but as a special glass: glass rib curtain wall system has developed rapidly in recent years. Traditional glass curtain walls require large steel keels to support the glass curtain wall system. The larger the span, the larger the cross-section of the steel keel, resulting in obstructed indoor and outdoor vision, and the facade presents large steel columns, which makes the indoor experience poor and the outdoor appearance visually unfriendly.

[0004] At present, buildings are no longer just objects that can be lived in. Buildings have become the symbol and memory of a city. Complex buildings are also the boosters of technological development. How to solve some special requirements of buildings, then new curtain wall systems will be born to meet the architects' extreme requirements for buildings.

The stainless steel cables 30 are arranged in the horizontal gaps between the hollow tempered glasses 10, and the hollow tempered glasses 10 are bonded into a whole piece by silicone weatherproof sealant 15. Tempered laminated glass ribs 20 are vertically arranged at the horizontal gaps of the hollow tempered glasses 10 by silicone structural adhesive 16, and the hollow tempered glasses 10 around the chamber 45 are fixedly connected by hidden cable ball joint clamps 40. The hanging assembly is arranged at the top position of the tempered laminated glass rib 20, and the horizontal pull rod assembly is arranged at the bottom connection of the tempered laminated glass rib 20. A glass chamfer 11 is provided at one corner of the hollow tempered glass 10, and the glass chamfer 11 is arranged to surround the chamber 45 of a rectangular structure.

[0036] The hidden cable ball joint fixture 40 includes a hard glass pad 41, a stainless steel glass support plate 42, a crimping groove 43, a glass connection hole 46 and a clip 47. The stainless steel glass support plate 42 is arranged at the gap between the hollow tempered glass 10, the hollow tempered glass 10 is arranged in the crimping groove 43 through the hard glass pad 41, the hollow tempered glass 10 is pressed in the glass connection hole 46 through HY70 injection adhesive and M27 stud bolts 28, and the clip 47 is crimped with the tempered laminated glass rib 20 through stainless steel bolts.

[0037] The cable fixing member 50 includes a first pressing block 51 and a second pressing block 52, and a stainless steel cable 30 is pressed between the first pressing block 51 and the second pressing block 52.
