AI Technical Summary
When existing building roofs are exposed to rain or damp environments, moisture can easily penetrate into the interior, leading to structural corrosion and affecting service life and load-bearing capacity.
The anti-slip texture and polyurethane coating layer enhance adhesion. The sealing structure combines a U-shaped channel, a sealing groove, a closed-cell foam strip, and sealant. A stable connection is achieved through anchor bolts and connecting mechanisms. Expansion bolts are used to fix the water guide channel. The water guide channel is designed to match the U-shaped channel to collect and guide accumulated water.
It effectively prevents roof leakage, avoids erosion by water and corrosive substances, enhances the overall stability and load-bearing capacity of the roof, extends its service life, and improves building safety.
