Research and Application Analysis of Anti-Detachment Measures for UHPC Facade Panels in High-Rise Residential Buildings

With the acceleration of urbanization, high-rise residential buildings increasingly prioritize safety and durability when selecting exterior wall decoration materials. As a leading enterprise in the field of new architectural decoration materials, Qinglong Group, with 28 years of experience across the entire chain of detailed design, manufacturing, construction and installation, and after-sales maintenance for UHPC (Ultra-High Performance Concrete), GRC (Glass Fiber Reinforced Concrete), GRG (Glass Fiber Reinforced Gypsum), and GRP (Glass Reinforced Plastic) materials, deeply understands the importance of UHPC exterior wall panel anti-detachment technology in ensuring building safety. This article systematically analyzes anti-detachment solutions for UHPC exterior wall panels in high-rise residential buildings from three dimensions: material properties, technological innovation, and engineering practice.

### UHPC Material Properties: Building an Anti-Detachment Foundation at the Source

As a new composite material with ultra-high strength (compressive strength of over 150MPa), excellent toughness, and durability, UHPC's inherent physical properties provide natural advantages for the anti-detachment performance of exterior wall panels. Compared with traditional concrete, UHPC significantly improves crack resistance and interfacial bond strength by incorporating steel fibers or ultra-fine silica fume, fundamentally reducing the risk of detachment caused by material aging. Qinglong Group strictly complies with the industry standard "General Technical Conditions for Non-load-bearing Components of Ultra-High Performance Concrete (UHPC)" in production. Through precise control of the water-binder ratio and curing processes, it ensures that every UHPC exterior wall panel meets mechanical performance requirements, laying a safety cornerstone for high-rise applications.

### Anti-Detachment Technology Innovation: A Full-Chain Solution in Practice

During the detailed design phase, the Qinglong team employs BIM technology and parametric modeling to conduct simulation analysis of wind pressure loads at different floor heights, optimizing anchor node design. For example, in a 30-story residential project, an innovative composite anchoring system of "stainless steel undercut anchor + aluminum alloy keel" was adopted. Through mechanical locking and elastic buffering structures, it effectively dissipates thermal deformation stress, increasing pull-out resistance by 40% compared with traditional hanging systems. In the manufacturing stage, automated production lines and 3D scanning inspection are introduced to ensure panel dimensional accuracy errors are controlled within ±2mm, reducing stress concentration caused by installation gaps. During construction, laser positioning technology achieves "zero-error" installation, and pull-out force tests are conducted on every anchor point, with data uploaded in real time to the quality traceability system, forming a fully traceable safety closed loop.

### Engineering Application and After-sales Maintenance: A Dual Guarantee of Long-Term Safety

Qinglong UHPC exterior wall panels have been successfully applied in many high-rise residential projects across the country, such as a 45-story super high-rise community in South China, where a composite structural design of "UHPC + insulation layer" was adopted, achieving lightweight construction (weighing only 1/3 of traditional stone) while meeting both energy-saving and anti-detachment requirements. After project delivery, relying on an after-sales network covering the whole country, regular inspection services are provided, using drone infrared detection technology to identify potential hazards. In addition, the "Ultra-High Performance Concrete (UHPC) Exterior Wall Panels" standard, which Qinglong participated in drafting, provides standardized guidance for the industry's anti-detachment technology, demonstrating the company's technical authority in the field of new decorative building materials.

As a national high-tech enterprise and a specialized and innovative enterprise, Qinglong Group has always taken "creating aesthetic architecture" as its mission, deeply integrating material innovation with engineering safety. In the future, Qinglong will continue to explore composite application technologies of UHPC with GRC, GRG, and other materials, providing safer and more economical solutions for high-rise residential exterior wall systems and contributing to the high-quality development of the construction industry.
