Discussion on Design Methods and Key Technologies for Connection Joints Between UHPC Curtain Wall Panels and Steel Frame Keels

As the "outer garment" of modern architecture, a building curtain wall owes its safety and aesthetics to the precise design of every connection node. In the application of ultra-high performance concrete (UHPC) curtain wall panels, the design of connection nodes with steel frame keels is the core factor that determines overall project quality. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group leverages its full-chain technical strength to provide designers and owners with expert-level solutions ranging from detailed design to construction maintenance, perfectly integrating architectural art with structural safety.

**UHPC Curtain Wall Panel Connection Node Design: The Key to Balancing Mechanics and Aesthetics**

With ultra-high strength (compressive strength exceeding 150MPa), excellent durability, and good plasticity, UHPC has become an ideal choice for high-end building curtain walls. The design of its connection nodes with steel frame keels must address three core issues: stability of load transfer, adaptability to thermal deformation, and controllability of installation accuracy. Through parametric modeling and BIM technology, the Qinglong team breaks node design down into a trinity system solution of "load-bearing structure + adjustment mechanism + protection system," ensuring that each connection point can withstand external forces such as wind loads and dead weight while accommodating the displacement caused by thermal expansion and contraction of the building.

**Key Technical Breakthroughs: From Material Properties to Engineering Practice**

During the detailed node design stage, the Qinglong technical team focuses on the collaborative performance between UHPC panels and metal keels. By adopting a composite connection approach of "embedded parts + stainless steel connectors," combined with anti-corrosion coating treatment and elastic gasket cushioning design, they effectively resolve electrochemical corrosion and rigid collision issues between different materials. For example, in a landmark project featuring a large-span curved UHPC curtain wall, the team innovatively applied three-dimensionally adjustable nodes, keeping installation errors within ±2mm and perfectly presenting the flowing lines of the architectural design.

**Full-Chain Service Assurance: From Laboratory to Construction Site**

As a national high-tech enterprise integrating detailed design, manufacturing, and construction installation, Qinglong Group has established a full-process quality control system covering "material R&D - digital modeling - factory prefabrication - on-site installation - after-sales monitoring." In benchmark projects such as the Nanjing Road Century Plaza renovation, the team conducted 1:1 full-scale node load tests in advance to simulate performance under extreme conditions, and combined RFID chip traceability technology to ensure that the connection quality of every UHPC curtain wall panel is monitorable and traceable. This dual assurance of "laboratory data + engineering experience" is precisely the technical confidence built upon Qinglong's 28 years of industry accumulation.

**Industry Trends and Qinglong Practice: Letting Innovative Technology Serve Architectural Aesthetics**

As building envelope design grows increasingly complex, connection technology for UHPC curtain wall panels and steel frame keels is developing toward modularity and intelligence. Qinglong Group has participated in formulating industry standards such as the "General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC)," promoting the standardization of connection node design. From overseas projects in Southeast Asia to large domestic venues, Qinglong upholds the values of "honesty, dedication, trust, and collaboration," turning every connection node into a balance point between safety and aesthetics, and helping realize its mission of "creating beautiful architecture."

The vitality of architecture lies hidden in the craftsmanship of every detail. The design of connection nodes between UHPC curtain wall panels and steel frame keels is both a technical challenge and a medium of artistic expression. Founded on 28 years of full-chain experience, Qinglong Group uses professional technology to make building curtain walls safe and reliable while radiating the beauty of design, standing as a well-deserved leader in the UHPC/GRC/GRG/GRP niche segment.
