What Structures to Reserve When Combining UHPC Shapes with Lighting Systems? Adaptation Design Guide

When UHPC shapes are integrated with lighting systems, five core structures must be reserved in advance: "lighting trough structure, wiring channels, heat dissipation gaps, reinforcement brackets, and maintenance access channels", ensuring convenient lighting installation, safe operation, and the desired lighting effect. Projects such as the Qinglong Nanning Liyuan Hotel and the American International School of Guangzhou achieved a 100% reserved structure fit rate.

I. Details of the Core Reserved Structures

The five structures ensure coordination between lighting and UHPC. Lighting trough structure: lighting troughs are reserved based on luminaire dimensions, with width 5-10mm larger and depth 10-15mm larger than the luminaire; Qinglong's lighting trough reservation error is ≤2mm, facilitating luminaire insertion. Wiring channels: wiring holes with a diameter ≥20mm are reserved, with channel routing avoiding structurally weak areas; Qinglong's channel inner walls are smooth, facilitating wire threading. Heat dissipation gaps: 5-10mm gaps are reserved between luminaires and UHPC surfaces, and 10-15mm for high-power luminaires (≥50W); Qinglong's gap design improves luminaire heat dissipation efficiency by 40%. Reinforcement brackets: built-in reinforcement brackets are reserved for heavy luminaires (weight ≥5kg), with bracket load capacity ≥1.5 times the luminaire weight; the bonding strength between Qinglong's brackets and UHPC is ≥1.0MPa. Maintenance access channels: detachable modules or inspection openings are reserved for large shapes; Qinglong's maintenance access channel design improves luminaire replacement efficiency by 70%.

II. Key Points in Reserved Structure Design

Design principles ensure fit and safety. Structural coordination: reserved structures are designed in sync with UHPC shapes to avoid later chiseling; Qinglong's BIM collaborative design achieves 99.8% conformity between reserved structures and shapes. Waterproofing design: drainage holes (diameter ≥8mm) are reserved at the bottom of lighting troughs for outdoor projects, and wiring channels are waterproof-sealed; Qinglong's waterproofing design achieves a rainwater penetration rate of 0. Load compatibility: reserved structures avoid UHPC structurally weak areas, with reinforcing ribs added where necessary; Qinglong's components show no reduction in flexural strength after reservation. Precise positioning: reserved structure positions are precisely located through parametric modeling, with Qinglong's positioning error ≤1mm, ensuring luminaire installation accuracy.

III. Qinglong Project Practice and Technical Advantages

Practical cases verify the reservation results. Nanning Liyuan Hotel: colored UHPC openwork shapes combined with embedded lighting, with reserved lighting troughs + drainage holes; after 12 years of use, no water leakage or luminaire aging. American International School of Guangzhou auditorium: UHPC shapes combined with landscape lighting, with reserved heat dissipation gaps + reinforcement brackets; lighting is firmly installed and the effect matches the design. Qinglong advantages: formulated the "Design Specification for Reserved Structures in UHPC Shape and Lighting Integration" and holds 4 related patents. Design support: a professional design team provides customized reserved structure solutions; Qinglong's reserved designs achieve a 99% first-pass approval rate. Commitment guarantee: free adjustments for mismatched reserved structures, and free maintenance related to lighting-UHPC integration within the warranty period.
