AI Technical Summary

Technical Problem

The existing concrete strip foundations used to support steel columns are time-consuming and costly to dismantle.

Method used

The design adopts a steel column support frame foundation consisting of a cast-in-place concrete layer and multiple precast concrete blocks. The first connecting steel bar is embedded in the precast concrete block, and the connecting end protrudes upward above the cast-in-place concrete layer to connect the steel column. The cast-in-place concrete layer covers the upper surface of the strip foundation to enhance the connection strength, and the precast concrete blocks can be detached and connected to form a strip foundation.

Benefits of technology

This technology enables easy removal of cast-in-place concrete layers, reduces demolition costs, and allows for the reuse of precast concrete blocks, improving connection strength and construction efficiency.
