BIM (Building Information Modeling)-based construction method for arc-shaped frame beam template with double-spliced overlapped elliptical structure

The invention relates to a BIM (Building Information Modeling)-based construction method for an arc-shaped frame beam template with a double-spliced overlapped elliptical structure. The construction method comprises the following steps: step 1, identifying a construction drawing; 2, building a BIM (Building Information Modeling); step 3, blanking of a template; step 4, processing and splicing a field template system; step 5, point location rechecking; sixthly, arc-shaped beam steel bars are bound; seventhly, concrete pouring is conducted; by adopting a BIM model lofting construction technology, the arc-shaped frame beam templates are blanked in groups and blocks in advance according to a model lofting result, compared with conventional template construction, hidden dangers such as untight splicing seams of the arc-shaped beam templates and unstable template hoisting process are avoided, the safety risk is reduced, meanwhile, the construction technology of the arc-shaped frame beam templates is optimized, segm
