Therefore, the construction safety and quality of the ultra-high concrete frame columns of the framed bent are particularly crucial. The most critical difficulty in the construction of ultra-high concrete frame columns is the formwork support safety and the verticality control of the frame columns. It is not easy to ensure the one-time formwork support and concrete pouring, so segmented pouring is mostly adopted. The difficulty lies in the construction of the upper structure, and conventional formwork support cannot be carried out. Therefore, choosing a reasonable method for connecting the height of the formwork plays a key role in ensuring safety, quality, and feasibility. Content of the Utility Model
