Parameterization design method for deepened drawing of assembled monolithic concrete prefabricated staircase

The invention relates to a parameterization design method for a deepened drawing of an assembled monolithic concrete prefabricated stair, which comprises the following steps: determining deepened key parameters according to a detailed drawing of a prefabricated stair component, and constructing a parameter table; according to the design data, specific data of the corresponding deepening key parameters are obtained in combination with specific prefabricated stair components; correspondingly filling the specific data into the parameter table, and classifying and splitting to obtain a deepened parameter table in combination with different types of the prefabricated stair members; and a deepening parameter table corresponding to the detailed drawing is inserted or drawn in the deepening drawing of the prefabricated stair component. Compared with the prior art, the method has the advantages that key information such as the size, the reinforcement, the steel bar structure and the reserved embedding of the prefabric
