AI Technical Summary

Technical Problem

In existing technologies, the termination structure of waterproof membrane on roof parapet walls requires a large number of screws for fixing, which makes it difficult to fix on the thin concrete parapet wall and may damage the main body of the parapet wall, thus reducing the efficiency of waterproof membrane termination.

Method used

The design employs a combination of wedge grooves and extrusion strips to secure the waterproof membrane. The waterproof membrane is fixed by the securing unit between the extrusion strips in the wedge grooves and the lower extension strips. Elastic elements and guide posts ensure a firm fixation without damaging the parapet wall. The integrated casting of the lower wall and roof enhances the waterproofing effect.

Benefits of technology

It enables simple and quick sealing of waterproof membrane, avoids damage to the main structure of the parapet wall, and improves the waterproof performance of the parapet wall.
