BIM-based prefabricated component rebar data processing method and device

The invention discloses a BIM-based prefabricated component rebar data processing method and device. The method comprises the following steps of: obtaining an outer contour entity model for establishing components; virtually splitting the outer contour entity model, and endowing each split rebar component with unique identification information; determining attribute information of the rebar components, wherein the attribute information comprises shape information, volume information and weight information of rebar; and carrying out statistical analysis on each rebar component according to theidentification information and the attribute information so as to generate rebar list information, and uploading the rebar list information to a database to store. According to the method and device,information such as rebar lists and the like can be directly and statistically analyzed through autonomously analyzing data on the basis of a BIM process model, so that the manual workload is greatlydecreased, the working effi
