ما تباعد التركيب في GRC؟ تشينغلونغ GRC تشرح تقنية التحكم في الوصلات

The control of GRC installation spacing directly affects the building's appearance and waterproofing performance. Based on Qinglong's 28 years of engineering experience, joint width must be comprehensively determined according to factors such as component dimensions, material properties, and thermal deformation, typically controlled within a range of 5-15mm.

In the Shanghai Xinghewan project, GRC decorative line joints were uniformly controlled at 8mm and filled with elastic sealant, which both allowed space for thermal expansion and contraction and achieved a perfect visual effect. This refined joint control keeps the building facade neat and attractive.

Principles for Determining Joint Width

Joint width is positively correlated with component size. It is typically set at a ratio of 1mm per meter, but must not exceed 15mm. In the Shenzhen Yirui Biotechnology Building project, joints for large-sized panels were controlled at 12mm, which was verified to fully meet deformation requirements.

Joint Treatment for Special Areas

Internal and external corner areas require appropriately wider joints. The corner areas of the Wuhan Hanxiu Theater project used 15mm joints with a dedicated sealing system, and this design has withstood years of weathering.

Consideration of Thermal Deformation Effects

Different climate zones require differentiated settings. Joint widths in Hainan projects are generally larger than in northern regions, and this differentiated design was successfully applied in the Poly Peninsula No. 1 project.

Setting GRC installation spacing requires professional technical support. It is recommended to engage a professional manufacturer for specialized design, ensuring that both functional requirements and aesthetic effects are met.
