AI Technical Summary
When using existing technology to reinforce ultra-high exterior walls with tripods, the height of conventional tripods is insufficient, resulting in the need for custom-made, heightened tripods, which are expensive, difficult to install, and have a large self-weight.
An extension frame is installed at the top of the tripod and fixed to the lower floor slab with reinforcements such as anchor bolts. The frame is formed by cantilever beams and diagonal braces to support the extension frame and ensure structural stability.
This approach reduces costs and installation difficulty, while improving structural stability and construction efficiency during the formwork erection process for ultra-high exterior walls.
