How to Design Connection Joints Between UHPC Curtain Wall Panels and Steel Frame Keels: Joint Engineering and Structural Innovation at Qinglong Group

The connection joint design between UHPC curtain wall panels and steel frame keels must achieve three major functions: "reliable load transfer, allowable deformation, and corrosion resistance." The core elements include joint types (hinged, rigid), connector selection (hangers, bolts), and anti-corrosion treatment. In the wave roof of the Hainan International Convention and Exhibition Center, Qinglong Group adopted three-dimensionally adjustable hinged joints (horizontal adjustment ±15mm, vertical ±10mm) with joint pull-out resistance ≥8kN; after 10 years in a hot and humid environment, there has been no corrosion. Joint design must be optimized through finite element analysis to avoid stress concentration and ensure safety under seismic and wind loads.

Joint Types Adapt to Deformation Requirements

Hinged joints are used in areas with large thermal deformation, and energy dissipation devices are added in seismic fortification zones. We determine the joint degrees of freedom through calculation. At the Wuhan Hanxiu Theater, hinged joints successfully absorbed deformation. Scientific selection ensures long-term stability.

Connector Materials and Anti-Corrosion

Stainless steel connectors (Grade 316 or above) and hot-dip galvanized steel frames. Qinglong Group's joints have passed salt spray testing and durability verification. Regular inspections prevent problems before they occur.
