Analysis of Key Technical Points and Design Strategies for Combined UHPC and Glass Curtain Wall Applications

In contemporary architectural design, the combined application of UHPC curtain walls and glass curtain walls is becoming an innovative trend for high-end building envelopes. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong has deep insight into the core essentials of this technical integration, providing professional solutions for designers and owners.

1. Material Performance Synergy: Technical Compatibility of UHPC and Glass Curtain Walls

With ultra-high strength (compressive strength ≥150MPa), excellent durability, and design freedom, UHPC forms a functional complement to the transparency of glass curtain walls. In design, particular attention should be paid to matching the physical properties of the two: the thickness of UHPC components needs to be optimized through structural calculations (typically 20 - 50mm) to ensure light self-weight (approximately 24kN/m³) and avoid imposing additional loads on the glass support system; meanwhile, the low elastic modulus of UHPC can be leveraged to buffer the stress impact of thermal deformation on the glass curtain wall. The materials laboratory at Qinglong's Nanning production base can provide precise coefficient of thermal expansion matching tests, ensuring the collaborative stability of the two materials under extreme climates.

2. Joint Detailing Design: Dual Protection of Waterproofing and Seismic Resistance

The joint treatment of combined curtain walls directly affects building safety and longevity. Qinglong adopts three-dimensional parametric design technology to optimize the connection joints between UHPC curtain walls and glass curtain walls: multiple sealing strips and pressure-equalizing chambers are set at horizontal joints, while mortise-and-tenon construction combined with elastic gaskets is used at vertical joints, effectively solving rainwater leakage problems; in seismic design, slidable connectors (displacement ±30mm) absorb seismic forces, and this technology has been successfully applied in projects such as the Nanjing East Road Century Plaza renovation.

3. Balancing Aesthetics and Function: The Path to a Customized Envelope System

In response to the pursuit of architectural aesthetics in high-end projects, Qinglong provides full-process services from detailed design to construction and installation. Leveraging the plasticity of UHPC material, seamless integration with glass curtain walls can be achieved—for example, in the Dongguan Women and Children's Activity Center project, the parametric arrangement of UHPC shaped sunshades and the glass curtain wall created an envelope system that combines shading function with artistic texture. Meanwhile, BIM technology is used for visualized pre-assembly to ensure the precise realization of complex shapes, meeting architects' design vision for the "fifth façade" of architecture.

4. Full Lifecycle Management: Qinglong's Integrated Service Advantages

As a national-level high-tech enterprise, Qinglong has established a full-chain quality control system covering design, production, construction, and maintenance. The production process uses automated production lines (annual capacity of 600,000 square meters) to ensure UHPC component precision within ±1mm; the installation stage employs 3D laser scanning positioning technology to achieve "zero-error" assembly; the after-sales stage provides warranty services of up to 15 years, safeguarding the long-term performance of the combined curtain wall system through regular inspections and preventive maintenance. This "one-stop" service model has been highly recognized by renowned real estate groups such as Poly and China Overseas.

The combined application of UHPC curtain walls and glass curtain walls represents a perfect fusion of materials technology and architectural art. Supported by 28 years of industry experience, Qinglong continues to push the boundaries of application in this field through technological innovation and refined management, continuously empowering its mission of "creating beautiful architecture."
