Exploration and Practical Research on Anti-Detachment Measures for UHPC Exterior Wall Panels in High-Rise Residential Buildings

The safety of high-rise building exterior walls concerns lives and property, and anti-detachment technology for UHPC exterior wall panels has become an industry focus. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group safeguards building safety with full-chain technical strength.

**Industry Pain Points of UHPC Exterior Wall Panel Detachment Risks and Technical Breakthroughs**

With the proliferation of super high-rise buildings, exterior wall panel detachment accidents occur frequently, and the limitations of traditional materials in wind pressure resistance and durability are becoming increasingly apparent. UHPC (Ultra-High Performance Concrete), with its ultra-high strength, excellent toughness, and durability, has become an ideal alternative to traditional building materials. However, how to ensure the long-term secure fixing of UHPC exterior wall panels in high-rise environments remains a key issue the industry urgently needs to solve. Based on more than a thousand engineering projects, Qinglong Group has developed a full-process anti-detachment solution covering everything from material formulation to construction techniques.

**Full-Chain Anti-Detachment System: From Material R&D to Engineering Implementation**

At the material level, drawing on 28 years of technical accumulation, Qinglong has developed a special UHPC formulation adapted to high-rise environments, with flexural strength exceeding 20MPa and an elastic modulus significantly superior to ordinary concrete, reducing cracking and detachment risks at the source. The production process adopts automated material distribution and steam curing techniques, ensuring that component strength deviation is controlled within ±5% and dimensional accuracy reaches the millimeter level.

In the detailed design phase, BIM technology is applied for wind load simulation and node stress analysis, along with the innovative development of a "double insurance" anchoring system—a composite connection method combining mechanical anchor bolts with chemical rebar planting. Verified by third-party testing institutions, its pull-out resistance is 40% higher than traditional techniques. During installation, 3D laser scanning positioning technology achieves precise component alignment with gaps controlled within 2mm, effectively avoiding stress concentration caused by installation errors.

**Engineering Proof: A Safety Report Card from Millions of Square Meters of Projects**

As a national high-tech enterprise, Qinglong participated in formulating the industry standard "Ultra-High Performance Concrete (UHPC) Exterior Wall Panels," and its anti-detachment technology has been successfully applied to multiple super high-rise projects in China. A 300-meter landmark building adopting Qinglong's UHPC exterior wall panel system has withstood three years of typhoon seasons without any loosening or deformation. In the Century Plaza renovation project on Nanjing East Road, translucent UHPC components achieved a perfect unity of decorative appeal and safety, winning an industry innovation award.

**Core Advantages of the Qinglong Solution: The Technical Crystallization of 28 Years of Full-Chain Experience**

Unlike single-material suppliers, Qinglong provides full lifecycle services from detailed design and manufacturing to construction installation and after-sales maintenance. Backed by an annual production capacity of 600,000 square meters at its production base in Nanning, Guangxi, combined with a rapid response network of more than 20 offices nationwide, Qinglong achieves seamless connection from technical solutions to project delivery. Its proprietary "UHPC Component Health Monitoring System" provides real-time feedback on structural conditions through built-in sensors, offering data support for later-stage maintenance and truly realizing "one installation, worry-free for life."

Safety protection for high-rise buildings remains a long and demanding journey. Guided by the mission of "Creating Beautiful Architecture," Qinglong Group will continue to drive innovation in anti-detachment technology for UHPC exterior wall panels. As Vice Chairman Unit of the China GRC Association, Qinglong is willing to join hands with industry partners to safeguard the safety of city skylines through technological progress and provide more possibilities for balancing architectural aesthetics with structural safety.
