AI Technical Summary

Technical Problem

The existing antique-style building floor tiles have poor moisture resistance, which leads to salt precipitation when the ground becomes damp. Moreover, maintenance is inconvenient, requiring the complete removal and replacement of the underlayment and adjustment of the level, resulting in a long maintenance cycle.

Method used

The design incorporates a support structure and drying granules. The support structure is installed on the ground, bricks are stacked on top of the support structure, drying granules are filled inside the support structure, and a buffer layer is bonded to the bottom of the bricks to form a three-dimensional moisture-proof system. The support structure and buffer layer, together with the support frame and air duct structure, enable modular maintenance.

Benefits of technology

It effectively prevents ground dampness, keeps brick humidity within a reasonable range, extends brick life by 2.3 times, reduces maintenance time by 80%, improves installation accuracy, reduces brick breakage, and enhances construction efficiency.
