AI Technical Summary

Technical Problem

In ultra-low energy consumption projects, the construction of embedded parts using existing technologies has problems such as disrupting the continuity of the insulation layer, forming cold bridges, high construction costs, great management difficulties, and many safety hazards.

Method used

The system employs pre-molded embedded parts, insulation layer, and concrete in a single process at the PC factory. Through a combination structure of steel plates, sleeves, and anchor bars, it reduces the need for through holes and trenches, ensuring the integrity of the insulation layer and enabling detachable connections of the connectors. This avoids welding and improves construction efficiency.

Benefits of technology

It significantly reduces the cold bridge effect, ensures the continuity and integrity of the insulation layer, reduces construction quality problems, lowers costs, improves construction efficiency and safety, and meets the energy-saving requirements of ultra-low energy consumption buildings.
