How Many Connection Methods Are There Between UHPC Decorative Components and the Main Structure? Connection Technology and Qinglong Group System Solutions

The connection of UHPC decorative components to the main structure falls mainly into four categories: dry-hanging, point support, adhesive bonding, and composite connection. The optimal solution must be selected based on component dimensions, wind load, and thermal deformation. Qinglong Group has concluded from 28 years of practice: small profiles (weight <50kg) can use adhesive bonding (structural adhesive shear strength ≥10MPa); curtain wall panels are best suited to point support (undercut anchors or diagonal tension rods); large components (>100kg) require a dry-hanging system (steel frames or aluminum alloy hangers). For the wave-shaped roof of the Hainan International Convention and Exhibition Center, we innovatively adopted a "three-dimensionally adjustable steel hanger + elastic adhesive joint" connection that absorbs thermal deformation of ±10mm and has remained secure through 10 years of typhoons. Connection design is the core of UHPC curtain wall safety.

Dry-hanging systems are the most common solution

Components are hung on the structure via steel frames or aluminum alloy framing, with connection point spacing ≤600mm. Qinglong Group's patented hangers allow adjustment of ±15mm up, down, left, and right, absorbing construction tolerances. In the Shenzhen Yirui project, the hangers achieved 15kN in tensile testing, with a safety factor ≥5.

Point support suits large panels and translucent designs

Stainless steel undercut anchors (embedment depth ≥40mm) or floating connectors are used to minimize visual obstruction. In the translucent UHPC panels of the Nanning New Media Center, four-point support achieves a "floating" effect.

Adhesive bonding and composite connections for special scenarios

Small indoor components can be bonded with epoxy structural adhesive; seismic zones use a composite "hanger + adhesive" connection. Qinglong Group prepares a connection calculation report for every project to ensure complete reliability.

The connection method determines the system's lifespan. Qinglong Group provides a complete solution from calculation and selection to installation, making connections both safe and aesthetically pleasing.
