ما هي مسافات تركيب GRC؟ معايير التحكم في عرض فواصل التركيب من تشينغلونغ لـ GRC

The GRC installation joint width must be determined comprehensively based on panel dimensions, thermal deformation, construction tolerances, and other factors, generally controlled at 6-12mm. A joint width that is too small may crack due to thermal deformation, while one that is too large affects 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 width. After withstanding two winters and summers, the panel joints showed no abnormalities, proving the joint width settings were reasonable.

Calculating Joint Width for Thermal Deformation

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 tolerance ±1mm, installation tolerance ±2mm. Cumulative errors must be absorbed within the joint width. Large-area installations require adjustment joints. Error control ensures uniform joint width.

Aesthetic Joint Width Design

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

Functional Joint Width Determination

Areas with high waterproofing requirements should have appropriately wider joints. Seismic joints are set according to standards. Movement joints correspond to structural joints. Functional requirements take priority.

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