AI Technical Summary
In existing technologies, the excessive wall thickness of circular structures makes it impossible to support formwork on both sides, requiring separate formwork on the inner side. Furthermore, when the side wall height is high, the diagonal bracing of single-sided formwork cannot meet the stress requirements of the inner formwork, resulting in construction limitations.
The ring-shaped internal mold support system, including a central positioning rod, a support disc assembly, and custom steel components, utilizes bolts and plug-in installation methods, combined with horizontal and vertical connecting rods, to form a stable support system suitable for single-sided support of circular structures.
It achieves stable support for the circular structure, improves construction safety and efficiency, facilitates disassembly, and enhances construction quality and safety performance.
