Concrete shell structure construction formwork modeling method

According to the concrete shell structure construction formwork modeling method, a simplified model of a bent frame system comprises point positions and lengths of all rod pieces of a bent frame, and parameters can be rapidly extracted to provide a material list for site construction. The simplified model can be converted into a high-precision BIM model from the simplified model through model replacement parameter conversion, and the requirements of different construction requirements, model lightweight, BIM visual disclosure, high-precision three-dimensional models and the like are met. The problem that a framed bent model cannot be opened and analyzed due to the too large framed bent model in construction deepening design is solved. On-site construction efficiency is effectively accelerated, on-site construction operation can be conveniently guided, and construction quality is improved. By increasing the erection area of the framed bent, the material consumption for customizing and processing the wooden kee
