AI Technical Summary

Technical Problem

In existing technologies, the elastic components of prefabricated assembled buildings are prone to deformation, which leads to frequent replacement of the waterproof layer, resulting in high maintenance costs and affecting construction quality.

Method used

The waterproof structure combines a concrete guide wall and a water-stop steel plate with a flexible waterproof layer. By setting a groove for the steel plate in the concrete guide wall and embedding the water-stop steel plate, and installing a flexible waterproof layer on the outside, a double waterproof design is formed to adapt to structural deformation.

Benefits of technology

Reduce leakage risk, improve durability, reduce maintenance needs, enhance building quality, shorten construction cycle, avoid secondary repairs, and extend service life.
