Steel Truss Type Spider Fitting Curtain Wall Wind Resistant For Commercial Building

Point Supported Curtain Wall – Steel Truss Type is a high-performance building envelope system that secures glass curtain walls to steel truss structures via independent point-supported connectors. Centered on the design philosophy of "structural transparency," it maximizes the purity of glass and the sense of spatial openness. The system employs custom-welded steel trusses as the primary supporting structure, with member cross-sections and node forms optimized through finite element analysis to create a spatial grid that combines mechanical efficiency with visual lightness. Each connection node utilizes a stainless steel point-supported system, including floating head connectors, prestressed anchor bolts, and three-dimensionally adjustable bases, enabling flexible displacement compensation for glass panels under wind loads, thermal deformation, and seismic actions.

Glass panels typically use large-sized laminated tempered glass or insulating laminated composite glass, connected via back-drilled holes and point-fixing claws to form load-bearing modes such as "four-point support," "six-point support," or "multi-point mesh support." All metal components are surface-treated with matte fluorocarbon coating or electrolytic polishing, ensuring durability while minimizing visual presence. The system pays special attention to detailed sealing design: glass joints combine silicone structural sealants with open drainage channels, ensuring airtight and watertight performance while avoiding visual obstruction.

This system is suitable for public buildings such as sports stadiums, transportation hubs, and cultural centers that require large-span column-free spaces. The steel trusses can be prefabricated in factories and assembled modularly on-site, significantly shortening the construction timeline. Glass panels support cold bending or hot bending for curved surfaces, meeting the requirements of double-curved architectural forms. By deeply integrating structural logic with light and shadow effects, the point-supported curtain wall – steel truss system redefines the symbiotic relationship between transparency and structural expression in modern architecture with precise industrial aesthetics.
