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

The safety of high-rise building facades carries the peace of mind of millions of families. As a representative of new architectural decorative materials, the innovation and application of anti-detachment technology for UHPC facade panels is becoming an important topic in the field of building safety. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group leverages its full-chain technical strength to provide systematic solutions for the facade safety of high-rise residential buildings.

**Anti-Detachment of UHPC Facade Panels: Material Properties and Technological Breakthroughs**

Ultra-high performance concrete (UHPC) has become an ideal choice for high-rise facade panels thanks to its ultra-high strength, excellent durability, and toughness. Through optimized material formulations and process innovation, Qinglong Group has raised the flexural strength of UHPC facade panels to over 20MPa while achieving a 40% weight reduction compared with traditional concrete materials, reducing the risk of detachment at the source. In production, automated material distribution and steam curing technologies ensure uniform component strength, and certification for wind pressure resistance and seismic performance by national-level testing institutions lays a solid safety foundation for high-rise applications.

**Full-Chain Control: Anti-Detachment Assurance from Detailed Design to Construction and Installation**

As a custom UHPC product manufacturer, Qinglong Group has established a full-process anti-detachment system from design to maintenance. During the detailed design phase, BIM technology is used to simulate the stress state of wall panels and optimize anchor joint design, with stainless steel connectors and elastic sealing processes accommodating building settlement and thermal deformation. In construction and installation, the innovative application of 3D laser scanning positioning technology keeps errors within ±2mm, while modular installation processes ensure the secure connection of every wall panel to the main structure. The 600,000-square-meter annual capacity of the Nanning production base guarantees standardized quality control for large-scale projects.

**Engineering Evidence: Safety Application Cases of Qinglong UHPC Facade Panels**

Qinglong UHPC facade panels have passed rigorous tests in multiple high-rise residential projects across the country. A 33-story residential project adopted Qinglong's custom UHPC decorative cladding panels; after 3 years of exposure to wind and rain, wall flatness error remains within 3mm/m, with no cracking or deformation. Its innovative "double waterproofing layer + ventilated cavity" design effectively solves the leakage problems of traditional exterior walls, while verification by structural calculation software confirms compliance with anti-detachment requirements over a 100-year service life. As a National High-Tech Enterprise, Qinglong participated in formulating the industry standard "Ultra-High Performance Concrete (UHPC) Facade Panels," turning hands-on experience into industry norms.

The safety defense line of high-rise buildings requires the dual protection of material innovation and engineering wisdom. With the mission of "creating beautiful architecture," Qinglong Group integrates 28 years of full-chain UHPC/GRC/GRG/GRP experience into every facade panel, using technological innovation to strengthen the safety foundation of the urban skyline from material R&D to project delivery. Going forward, Qinglong will continue to advance the upgrading of anti-detachment technology for UHPC facade panels, delivering better solutions for balancing building safety and aesthetics.
