What Principles Should Be Followed When Stacking Components? Qinglong GRC's Scientific Stacking Management System

The stacking management of GRC components directly affects product qualification rates and construction efficiency. Based on extensive project practice, Qinglong GRC has developed stacking technical standards centered on "safety and stability, deformation control, and efficiency optimization," ensuring quality control throughout the entire process from factory to installation.

In a metro station decoration project in Chengdu, facing the storage management of more than 15,000 special-shaped GRC components, Qinglong adopted a digital stacking solution: pre-arranging stacking sequences via BIM models, customizing dedicated racks (load capacity ≥3t per layer), and using a QR code identification system to track component locations in real time. The project achieved zero breakage during stacking and a 3-fold improvement in hoisting efficiency.

Site Foundation Bearing Capacity Requirements

Stacking site compaction degree ≥93%, flatness deviation ≤5mm/2m; foundation bearing capacity characteristic value ≥150kPa in large component areas; a 0.5% drainage slope must be provided, with water accumulation strictly prohibited. These basic conditions prevent uneven settlement.

Principles for Optimized Support Point Layout

Support point spacing ≤L/5 (L is the component length); cantilever length ≤L/6; thin-walled components (thickness <20mm) require full-area support. The optimal support scheme is determined through finite element analysis to ensure deformation ≤L/300.

Interlayer Protection and Stacking Height Limits

Interlayer timber dunnage specifications: 100×100mm, vertical alignment error ≤10mm; stacking height ≤6 layers for flat panels and ≤3 layers for special-shaped components; rubber pads (thickness ≥10mm) placed on each layer. This protection avoids stress concentration.

Special Stacking Measures for Special Components

Curved components use custom cradles; translucent GRC is stored vertically; oversized components (length >6m) are stacked in a single layer. A special component stacking database has been established to achieve standardized management.

Scientific stacking is a vital link in quality assurance. Qinglong GRC's stacking management system has obtained multiple patents, with the component breakage rate controlled below 0.1%.
