How Should Temporary Supports Be Set Up When Installing GRC Panels? Construction Safety and Qinglong Group Support Specifications

Temporary support setup for GRC panel installation must follow the principle of "support first, then install; even load distribution; timely removal." Support point spacing is determined by panel thickness and span: spacing ≤1.2m for thickness ≤15mm, ≤1.5m for 15-25mm, and ≤2.0m for >25mm. In the 120,000-square-meter roof construction at the Hainan International Convention and Exhibition Center, Qinglong Group adopted an adjustable steel support system (load capacity ≥2kN/point), with support points offset from permanent hanging points by more than 300mm and installation error kept within ±3mm. Temporary supports are not only a safety measure but also a guarantee of precision. Through laser level calibration, we ensure panel surface flatness ≤2mm/2m, laying the foundation for subsequent procedures.

Support System Design and Calculation

Support frame stiffness must satisfy Δ≤H/500 (H is the frame height), with vertical post spacing ≤1.2m and horizontal ledger lift spacing ≤1.5m. Qinglong Group uses ringlock scaffolding, verified through calculation software. For shaped panel installation, custom support molds are fabricated to ensure accurate positioning of curved surfaces.

Support Timing and Removal Control

Panels are supported immediately after positioning, and supports are removed 24 hours after all connection points are fully torqued. We have established a support removal permit system, under which scaffolding may only be dismantled after confirmation by the quality inspector. In a Shenzhen project, meticulous support management improved installation efficiency by 30%.

Safety Monitoring and Emergency Response Plan

Support settlement is inspected daily, with reinforcement during windy or rainy weather. Qinglong Group's construction teams are fully certified, with zero accidents over 28 years. Standardized support is a dual guarantee of quality and safety.
