Research on Integrated Technology of Overall Aerial Building Formwork Equipment and Concrete Placing‐Boom

ABSTRACTThe overall aerial building formwork is an independently invented support equipment in China, specifically designed for the construction of concrete structures in super high‐rise buildings over 200 m. The integration of a concrete placing‐boom and integrated aerial building formwork equipment plays a crucial role in this new type integrated system. This article provides a comprehensive summary and analysis of the integrated connection structure between the existing concrete placing‐boom and the overall aerial building formwork equipment. It also presents an innovative design for a lightweight unit‐type formwork concrete placing‐boom integrated platform, along with detailed explanations of its structure design and construction process. Furthermore, calculations and analyses were conducted to determine maximum stress and deformation under various conditions such as climbing, steel bar binding and formwork synchronization operation and concrete pouring by using MIDAS finite element software. The results demonstrate that the maximum stress and deformation meet the control requirements effectively. This article invents a novel overall aerial building formwork equipment integrated with a concrete placing‐boom, compared to the existing integrated platform, the lightweight unit‐type formwork concrete placing‐boom integrated platform offers advantages including flexible assembly, strong structural applicability, excellent safety performance, high construction efficiency, superior load‐bearing capacity as well as overall performance enhancement. These features make it more suitable for meeting the specific construction needs of super high‐rise buildings over 200 m, and provided a new equipment for the construction of super‐high‐rise reinforced concrete core.
