Do Installation Methods Differ for GRC Components of Different Weights? Qinglong's Graded GRC Installation Technology System

The weight variation of GRC components directly affects the selection of installation plans, requiring different lifting, supporting, and connection methods based on weight classification. Based on extensive engineering data, Qinglong GRC has established a differentiated installation technical system with weight classification as the foundation and safety factors as the core.

In the Wuhan Tianhe Airport project, facing components of varying weights ranging from 15kg decorative moldings to 2.8t large arches, Qinglong developed a tiered installation plan: components ≤50kg are installed manually; 50-200kg use portable machinery; 200-1000kg are equipped with light lifting equipment; components ＞1t use truck cranes with specialized tooling. Through this tiered management, installation efficiency increased by 35%, with a zero safety accident rate.

Lifting Point Design Standards

Components ≤50kg are fitted with 2 lifting points; 50-200kg with 4 lifting points; components ＞200kg require specialized lifting point design. The lifting point safety factor is ≥4, verified through finite element analysis.

Differentiated Connection System Design

Lightweight components (＜100kg) use point connections; medium-sized components (100-500kg) use linear connections; heavy components (＞500kg) use unitized connections. The connection safety factor is ≥2.5.

Installation Equipment Selection Principles

≤200kg use hydraulic lifting platforms; 200-1000kg are equipped with small cranes; ＞1t uses large lifting equipment. Equipment load capacity must be at least 1.5 times the component weight.

Tiered Safety Protection Measures

≤50kg requires working surface protection; 50-200kg requires area isolation; ＞200kg requires specialized construction plans. A complete safety assurance system has been established.

Weight-classified installation requires scientific management. Qinglong GRC's installation system has been successfully applied to hundreds of projects, achieving the goals of zero safety accidents and fully excellent quality.
