Exploration and Practice of Anti-Detachment Measures for UHPC Exterior Wall Panels on High-Rise Residential Buildings

Research and Practice of Anti-Falling Measures for UHPC Exterior Wall Panels in High-Rise Residential Buildings

Building safety is no small matter. The risk of exterior wall panel detachment not only threatens lives and property, but also affects a building's aesthetics and durability. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group has always upheld the mission of "creating beautiful buildings." In the application of UHPC exterior wall panels for high-rise residential buildings, it has built an anti-falling safety system through full-chain technological innovation, providing practical, implementable solutions for the industry.

### The Technical Logic of Anti-Falling UHPC Exterior Wall Panels: Dual Safeguards of Material Properties and Structural Design

UHPC (Ultra-High Performance Concrete), with its ultra-high strength (compressive strength ≥150MPa), excellent toughness, and durability, has become the ideal material for high-rise exterior walls. During the detailed design phase, Qinglong Group leverages the technical advantages of its provincial R&D center to deeply integrate material properties with structural safety: fiber reinforcement technology is adopted to enhance the crack resistance of panels, while BIM parametric design optimizes panel dimensions and weight, ensuring that the self-weight of each UHPC exterior wall panel is controlled within 50kg/㎡ and significantly reducing installation loads. Meanwhile, drawing on experience from formulating the industry standard "Ultra-High Performance Concrete (UHPC) Exterior Wall Panels," Qinglong has innovatively designed a composite anchoring system of "dovetail grooves + stainless steel connectors," increasing the connection strength between panels and the main structure by more than 40%.

### Full-Process Quality Control: An Anti-Falling Defense Line from Production to Installation

As a national high-tech enterprise, Qinglong has established a full-chain quality control system covering detailed design, manufacturing, construction and installation, and after-sales maintenance. At its production base in Nanning, Guangxi, the intelligent production line with an annual capacity of 600,000 square meters is equipped with an online monitoring system that regulates key parameters such as UHPC raw material ratios and curing temperature in real time, ensuring a 100% factory pass rate for panels. In the construction phase, 3D laser scanning positioning technology achieves installation errors of ≤2mm, and a strict "double-inspection system" is enforced—checking both the anchoring depth of connectors and testing the pull-out resistance of panels. To address the impact of wind loads on high-rise buildings, the innovative "dynamic displacement compensation" technology has been applied, keeping exterior wall panels structurally stable within a displacement range of ±30mm. This technology has passed the Guangdong Province Scientific and Technological Achievement Appraisal.

### Engineering Practice and Long-Term Maintenance: Safety Verified by 28 Years of Experience

Qinglong UHPC exterior wall panels have been successfully applied in hundreds of high-rise residential projects across the country, demonstrating excellent anti-falling performance from the humid, hot regions of South China to the severely cold north. Taking a 33-story residential project as an example, the adoption of Qinglong's detailed design of the "UHPC insulation integrated exterior wall system" not only achieved the integration of insulation and decorative functions, but also verified wind pressure resistance through 100,000 fatigue vibration tests. In after-sales service, Qinglong has established "building health records," using IoT technology to regularly monitor key connection nodes, supported by a maintenance team with 2-hour rapid response, building a full lifecycle safety guarantee from "prevention" to "disposal." This integrated service model of "design-production-installation-maintenance" is precisely Qinglong's core competitiveness as a "full-chain supplier of UHPC/GRC/GRG/GRP."

The safety of high-rise residential exterior walls concerns public well-being. Guided by the principle of "meticulousness and the pursuit of excellence," Qinglong Group has transformed 28 years of industry experience into anti-falling technical solutions. Through material innovation, structural optimization, and full-process control, it has redefined the safety standards for UHPC exterior wall panels. Looking ahead, Qinglong will continue to pursue its vision of "becoming a world-class leading manufacturer of UHPC/GRC/GRG/GRP," providing more buildings with high-quality solutions that combine aesthetics and safety.
