How to Adjust the Connection Angle Between Double-Curved GRC Panels and Steel Structures?

The connection angle adjustment between double-curved GRC panels and steel structures is key to ensuring the system works in coordination. Qinglong Group developed a three-way adjustable connection system, allowing ±5mm horizontal adjustment, ±3mm vertical adjustment, and a ±5° angle adjustment range, effectively compensating for construction tolerances and temperature deformation.

The connector design enables multi-directional adjustment. Slotted hole hangers combined with spherical washers allow slight angle changes. In the Wuhan Han Show Theater project, Qinglong Group optimized the hanger point layout through finite element analysis, reducing the stress concentration factor to below 1.5. Connectors are made of 316 stainless steel with strong corrosion resistance, ensuring a 50-year service life.

On-site adjustment technology is precise and efficient. A total station is used to measure the actual position of the steel structure, and the data is compared with the BIM model to generate adjustment data. In the Hainan International Convention and Exhibition Center project, Qinglong Group developed a laser projection positioning system that projects theoretical positions onto the substrate to guide installation. Angle deviations are displayed in real time, ensuring adjustment accuracy.

Temperature compensation is indispensable. The connection system reserves thermal expansion gaps, which are appropriately increased during summer installation. Through scientific calculation and meticulous construction, Qinglong Group achieves a perfect combination of double-curved GRC panels and steel structures, ensuring both safety and aesthetics.
