ما تباعد التركيب في GRC؟ معايير التحكم في عرض وصلات التركيب

The installation joint width of GRC must be determined comprehensively based on factors such as panel dimensions, thermal deformation, and construction tolerances, and is generally controlled at 6-12mm. Joints that are too narrow may crack due to thermal deformation, while overly wide joints affect aesthetics.

In the Shenzhen Pingshan High-Tech Zone project, Qinglong set the installation joint width at 10mm based on local climate characteristics. 8mm was reserved for summer installation and 10mm for winter to accommodate thermal deformation. Special joint width control gauges were used to ensure uniform and consistent joint widths. After withstanding two winters and summers, the panel joints showed no abnormalities, proving the joint width settings were reasonable.

Thermal Deformation Joint Width Calculation

Calculate the deformation based on the local annual temperature range; 8-10mm is recommended for the Guangdong region. Large-area panels require appropriately wider joints. Expansion joints should be set at internal and external corners. Calculations must account for long-term deformation.

Construction Tolerance Control Requirements

Layout marking tolerance is ±1mm, and installation tolerance is ±2mm. Cumulative errors must be absorbed within the joint width. Large-area installations require adjustment joints. Tolerance control ensures uniform joint widths.

Aesthetic Joint Width Design

8-12mm is recommended for public buildings and 6-8mm for residential buildings. Horizontal joints may be slightly wider than vertical joints. Special-shaped areas require separate design. Joint width must coordinate with the architectural style.

Functional Joint Width Determination

Areas with high waterproofing requirements require appropriately wider joints. Seismic joints are set according to standards. Deformation joints should correspond to structural joints. Functional requirements are given priority.

Reasonable joint width design requires professional calculation and experience. With its extensive experience, Qinglong GRC provides customers with optimal solutions.
