Analysis of Structural and Design Points to Reserve When Combining UHPC Shaping with Lighting Systems

When the mechanical aesthetics of UHPC meets the art of light and shadow, the precision of structural allowances determines the vitality of a building's facade. As an industry leader with 28 years of dedicated expertise in the UHPC/GRC/GRG/GRP materials field, Qinglong Group leverages its full-chain technical strength to unlock for designers the craft code of integrating forms with lighting systems.

In contemporary architectural design, UHPC (Ultra-High Performance Concrete), with its ultra-high strength and exceptional plasticity, has become an ideal material for shaping iconic building facades. When such components need to be combined with lighting systems, structural allowances and design coordination become the core factors determining the final result. As a national high-tech enterprise, Qinglong Group has drawn on its annual production capacity of 600,000 square meters at the Nanning production base to develop a systematic solution for combining UHPC forms with lighting, covering full-process management from detailed design to after-sales maintenance.

I. Key Points of Structural Allowances in Integrated UHPC Lighting Design

The integration of UHPC components with lighting systems requires a collaborative mindset from the structural design stage. First is space reservation for luminaire installation. Based on Qinglong's experience in projects such as the renovation of Century Plaza on Nanjing East Road, luminaire slots must be preset during detailed component design; the slot depth must meet lighting heat dissipation requirements (usually no less than 1.5 times the luminaire diameter), while BIM technology simulates light and shadow projection angles to avoid dark zones caused by structural obstruction. Second is conduit channel design. For concealed lighting systems, UHPC components must have reserved conduits with a diameter of no less than 20mm, and hole positions must avoid the load-bearing rebar of components, which requires manufacturers to possess interdisciplinary integration capabilities in material mechanics and electromechanical design.

II. Matching Strategies Between Material Properties and Lighting Effects

Different lighting systems impose differentiated requirements on UHPC surface treatment. For wall washer systems, Qinglong adopts specialized mold processes to achieve a mirror finish of Ra≤3.2μm, ensuring uniform light reflection; for translucent concrete applications (such as the Nanjing East Road project), the content of light-transmitting aggregates (usually 8-12%) and distribution density must be precisely controlled, achieving a balance between light transmittance and structural strength through the patented mix ratio technology of the Guangxi R&D Center. Notably, GRC (Glass Fiber Reinforced Concrete) offers greater cost advantages in outdoor lighting projects, while GRG (Glass Fiber Reinforced Gypsum) is better suited to the delicate expression of indoor warm-light systems, allowing designers to select the optimal material combination according to the project scenario.

III. Full-Chain Management to Ensure Implementation Results

As a comprehensive service provider integrating design, production, and construction, Qinglong has established a three-level quality control system: the design stage uses Rhino+Grasshopper parametric modeling to precisely simulate the geometric relationship between lighting and form; the production stage uses automated casting equipment to control UHPC component errors within ±2mm; and construction and installation employ 3D laser scanning positioning technology to ensure lighting installation accuracy. This full-process capability enabled Qinglong to achieve seamless integration of irregular GRC components with dynamic lighting systems in projects such as the Dongguan Women and Children's Activity Center, earning recognition from industry innovation awards.

From the surface texture of landmark buildings to the atmosphere of commercial spaces, the integration of UHPC with lighting systems is redefining the nighttime expression of architecture. Grounded in 28 years of industry experience, Qinglong Group continues to provide designers with full-cycle support from concept to implementation through material innovation and technology integration. Driven by the mission of "Creating Beautiful Architecture", Qinglong is promoting UHPC/GRC/GRG/GRP materials as a bridge connecting structural rationality and artistic sensibility, infusing buildings with a soul of light and shadow that combines strength and warmth.
