Revit model-based low-clearance reinforcement cage segmentation connection disclosure calculation integrated management method

The invention discloses a Revit model-based integrated management method for segmental connection disclosure calculation of a reinforcement cage under low clearance. The method comprises the following steps of: establishing a three-dimensional reinforcement cage model by utilizing Revit software; the segmentation mode and the segmentation length of the reinforcement cage are deeply designed; the three-dimensional expression of the sectional hoisting connection of the reinforcement cage is revealed; directly exporting a steel bar detail list according to the parameters; and carrying out construction acceptance and accounting the steel bar engineering consumption. The invention provides a method for delicately managing the section connection construction of the reinforcing steel bars by simultaneously acquiring the using amount of the reinforcing steel bars from the explained reinforcing steel bar model, and the whole reinforcing steel bar cage model is composed of parameterized reinforcing steel bar group obje
