How Do UHPC Openwork Components Ensure Structural Strength of Openwork Areas? Openwork Reinforcement and Qinglong Group's Design Innovation

The structural strength of UHPC hollow-out components is ensured through three key technologies: "optimizing the hollow-out pattern, local reinforcement, and oriented fiber enhancement," with the core being to balance artistic expression and mechanical performance. In the hollow-out UHPC facade project for the Shenzhen Yirui Biotechnology Building, Qinglong Group used parametric design to optimize hole distribution (hole diameter ≤100mm, spacing ≥50mm), set 20mm-wide reinforcing ribs along hole edges, and applied 2.5% steel fibers (12mm long) to strengthen the edges, so that components with a 40% hollow-out ratio still achieve a flexural strength of 12MPa, far exceeding safety requirements. Hollow-out components are the ultimate expression of UHPC's high toughness; scientific design can achieve both aesthetics and safety.

Parametric Hole Design to Avoid Stress Concentration

Use finite element analysis software to simulate stress distribution under load and avoid placing holes in high-pressure zones. Rounded hole shapes (R≥10mm) are preferred to reduce stress concentration at sharp corners. Qinglong Group's Grasshopper algorithm library can automatically generate optimal hole arrays.

Local Reinforcement Construction Is the Key Measure

Reinforcing rings are set around hole edges (width ≥1.5 times the panel thickness), and cross ribs are added inside large holes (>150mm). For the hollow-out panels at Nanning Wuxiang China Resources MixC One, we used T-shaped ribs, which increased weight by 8% but raised strength by 30%.

Fiber Reinforcement and Special Process Assurance

In areas around holes, fiber content is increased to 3%; during spraying, robotic arms place fibers circumferentially around the holes. For ultra-complex hollow-outs, we use 3D printing technology to produce integral molds, ensuring fiber continuity.

Hollow-out components test both design and manufacturing capabilities. With 28 years of experience, Qinglong Group makes hollow-out UHPC lightweight and beautiful, yet solid and reliable.
