What Installation Technical Safeguard Measures Do Manufacturers Have? Construction System and Qinglong Group Precision Installation Solutions

The installation technical assurance measures of a GRC manufacturer cover five key aspects—technical briefing, measurement and layout, specialized tooling, process monitoring, and acceptance standards—forming a complete installation quality assurance system. Based on 28 years of installation experience, Qinglong Group has developed the "12345" installation assurance method: 1 set of 3D model guidance, 2 technical briefings (factory + site), 3 levels of layout verification (primary + secondary + final), 4 specialized tooling items (lifting devices + adjusters + sealing tools + protective materials), and 5-step acceptance standards (positioning → flatness → verticality → joint width → appearance). In the 120,000-square-meter roof installation at the Hainan International Convention and Exhibition Center, we adopted measures such as total station grid layout, 3D adjustable connectors, and laser level inspection, achieving a cumulative installation error of ≤±5mm for 28,700 double-curved panels and a joint uniformity of over 95%. Installation is the final realization of design and requires refined control.

Standardized Installation Procedures Are the Foundation of Quality

We prepare detailed installation work instructions that specify the key operating points and acceptance standards for each process. Installation personnel are certified for their posts and receive no less than 40 hours of training each year. In the Shenzhen Yirui project installation, we adopted a "model section leads the way" strategy, completing a model section first and rolling out large-scale installation only after it passed acceptance.

Precise Measurement and Layout Are the Prerequisite for Success

A total station is used to establish an installation control network with an accuracy requirement of ±2mm. Before installation, each panel undergoes 3D coordinate verification to ensure accurate positioning. For complex curved-surface installations, we use 3D laser scanning technology to achieve "digital twin"-guided construction.

Specialized Installation Tooling Is the Guarantee of Efficiency

Specialized lifting devices and adjusters are designed for different panel types. We hold more than 20 installation tooling patents, such as universal adjustable hangers and fine-adjustment jacking screws, which allow ±10mm of installation adjustment and effectively absorb structural construction deviations.

Full-Process Quality Monitoring Is the Core Link

The installation process implements a "three-inspection system": self-inspection, mutual inspection, and dedicated inspection. After each panel is installed, flatness, verticality, and joint width are inspected immediately, with data entered into the management system in real time. Deviations are corrected promptly to prevent error accumulation.

Installation quality determines the final result. Through systematic installation assurance measures, Qinglong Group ensures that every project perfectly presents the design intent.
