Resumen
Hydraulic automatic climbing formwork equipment is widely used in super-high-rise building construction due to its advantages of simple operation, fast construction speed, low cost, and high automation. Quantitative calculation of the mechanical state of climbing formwork equipment is an important technical means of ensuring safety during super-high building construction. This work thus introduces a hydraulic climbing formwork equipment structure and subsequently analyzes the construction process and the main working state of the hydraulic climbing formwork equipment. Then, for the design of the outer climbing frame of the hydraulic climbing formwork, an approximate analytical method for solving the node reaction force is proposed. Finally, combined with the actual engineering, the calculation results of the approximate analytical method and the finite element method are compared, and the calculation and analysis methods of the hydraulic climbing formwork equipment frame and key nodes are introduced. The calculation analysis process and related conclusions can be used as engineering reference for similar projects.
