What to Note When Combining UHPC Curtain Walls with Glass Curtain Walls?

The combined application of UHPC curtain walls and glass curtain walls requires close attention to four core points: "joint coordination, load matching, waterproof sealing, and aesthetic harmony." Through BIM detailed design and standardized joint techniques, Qinglong achieves seamless integration of the two. Multiple commercial complex projects with combined applications both showcase design appeal and ensure safety in use.

I. Joint Coordination: Seamless Connection of Structure and Installation

Joints are critical to combined application. Keel coordination: steel frame keels are designed as a unified system to ensure the keel spacing and load-bearing capacity of UHPC panels match those of the glass curtain wall; Qinglong uses BIM modeling to optimize keel layout and prevent uneven stress at joints. Installation sequence: the keel frame is installed first, then UHPC panels and the glass curtain wall are installed simultaneously, with a 10-15mm adjustment space reserved at joints; Qinglong's installation sequence has been verified through simulation with no process conflicts. Edge finishing: custom metal trims are used where UHPC panels meet the glass curtain wall, fitting tightly against both; Qinglong's trims are made of stainless steel, corrosion-resistant and attractive.

II. Load Matching and Waterproof Sealing: Ensuring Structural Safety and Waterproofing

Load management and waterproofing are the core safeguards of combined application. Load matching: the load difference between UHPC panels (self-weight approx. 60kg/㎡) and glass (self-weight approx. 25kg/㎡) must be balanced through keel reinforcement; Qinglong enlarges the keel cross-section in UHPC panel installation areas to ensure uniform overall load-bearing. Waterproof sealing: joints use "double sealing" (butyl sealant inside + weather-resistant silicone sealant outside) to prevent rainwater penetration; Qinglong's sealants are compatible with both UHPC and glass, with no corrosion. Drainage design: drainage channels (slope ≥3%) are installed at joints to promptly discharge accumulated water; Qinglong's drainage channels come with filter screens to prevent blockage by debris.

III. Aesthetic Coordination and Project Practice: Balancing Aesthetics and Practicality

Aesthetic coordination enhances the overall decorative effect. Unified style: the color and texture of UHPC panels are coordinated with the transparency and reflectivity of glass—for example, matte UHPC paired with Low-E glass; Qinglong can customize UHPC surface effects to create textural contrast with glass. Matching dimensions: the panel divisions and line directions of both remain consistent to avoid visual confusion; Qinglong makes adjustments through BIM visualization to ensure aesthetic unity. Project cases: Shenzhen Pingshan High-Tech Zone Comprehensive Service Center combines UHPC curtain walls with glass curtain walls, with joints sealed using stainless steel trims, a 100% waterproofing pass rate, and a clean, grand overall form, winning the Luban Award; Nanning Wuxiang China Resources MixC One pairs colored UHPC with transparent glass, satisfying daylighting needs while enhancing the commercial atmosphere, earning high recognition from the designers.
