Self-tapping self-drilling screw one-time fastening method and first drilling and tapping and screw fastening method
Once the panel is mounted and integrated into the curtain wall framework, the lightning protection system and fireproof layer are completed, followed by the installation of individual panels. The process includes: identifying and marking the board, positioning, cleaning the edges, filling joints, and ensuring cleanliness. First, the required aluminum panel model is temporarily selected based on the construction drawings. When storing aluminum panels, they must be clearly labeled and stacked according to the project's progress, as improper storage can lead to significant issues during installation.
Board assignment follows once all panel accessories are ready. Each panel is assigned to its designated position based on hole specifications to avoid confusion and mistakes. If any errors occur during the distribution, they should be corrected immediately to prevent unnecessary waste, such as missing pieces, scratches, or patchwork repairs. Once the panel is in place, it is adjusted to ensure proper alignment, flatness, and vertical/horizontal orientation. It’s crucial not to cause any deformation or looseness in the panel or its supporting structure. If a mistake is made during installation, the panel should be removed and reinstalled. In some cases, minor adjustments may be needed due to size or shape discrepancies. Any modifications should be done accurately on-site, with the new panel securely installed and free from obstructions.
Fastening methods include using self-tapping screws or drilling and tapping before screwing. Both techniques require precision, strength, and a secure fit. After installation, the protective film and debris around the panel’s edges should be cleaned to prevent water leakage and maintain waterproof integrity. Before filling the groove, dust, oil, and moisture must be removed. A polyurethane foam rod is then inserted, while special areas may use multiple roots, single splits, or polyethylene double tapes instead of standard materials.
This detailed process ensures that every step is carefully executed, minimizing errors and maintaining the quality and safety of the curtain wall system. Attention to detail at each stage is essential for a successful and long-lasting installation.
