AI Technical Summary

Technical Problem

The existing welded metal roof edge gutter joint installation structure is prone to loosening during installation, which leads to a decrease in joint sealing and increases the risk of rainwater leakage.

Method used

The metal roof panels are fixed to the corrugated water-blocking components, metal gutters, and inclined beams using wave-crest resistance welding and laser welding technologies. The metal gutters and gutter side beams are then fixed with self-tapping screws to form a fully fused structure, eliminating holes and gaps.

Benefits of technology

It achieves complete fusion of metal roof panels with inclined beams and metal gutters, preventing rainwater leakage, extending service life, reducing maintenance costs, and improving waterproof reliability and the stability of the installation structure.
