What Are the Reinforcement Measures for Hollowed-Out GRC Shapes? — Qinglong Group's Hollow Structure Reinforcement Technology

Enhancing perforated GRC forms requires balancing aesthetics with structural safety. Through fiber optimization, local reinforcement, and connection innovation, Qinglong Group ensures that components with perforation rates above 50% are safe and reliable.

Fiber reinforcement is the fundamental measure. Fiber content is raised to 3%-4%, using hybrid fibers (steel fiber + polypropylene fiber). In its Algeria hotel project, Qinglong Group applied directional fiber placement technology to achieve a flexural strength of 12MPa at perforated edges. Fiber length is optimized to 12-18mm with an aspect ratio of 60-80, ensuring effective crack bridging.

Key areas are locally reinforced. Concealed beams are added in perforated areas, with thickness increased by 20%-30%. Qinglong Group determined stiffening rib positions through topological optimization, reducing material usage by 15% while increasing strength by 20%. Local reinforcement is applied around connection points to avoid stress concentration.

Innovation in the connection system improves safety. Dedicated hangers have been developed to allow multi-dimensional adjustment. Perforated panels adopt four-point support, with hanger load capacity verified through simulation. These measures make perforated GRC both lightweight and safe.
