Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of nuclear power engineering steel bar processing, and more particularly to a nuclear power engineering steel bar digital cutting method and system. BACKGROUND

[0002] The civil engineering of a nuclear power station has many sub-items and large engineering quantities, and the steel bar reinforced concrete structure has dense steel bars, large steel bar consumption, and many steel bar varieties. For the entire project, the steel bar sub-item project is the most important. Steel bars play a crucial role in ensuring the safety of the structure of a nuclear power station. Not only is the consumption large and the varieties many, but also the specifications, sizes, and arrangements of the steel bars need to meet the design requirements in the construction process to ensure that the stress performance of the steel bars is optimal, the safety hazards of the building structure are reduced, and the quality standards are met.

[0003] The steel bar digital cutting process in the prior art mainly includes a cutting method relying on a two-dimensional drawing tool and a cutting method based on three-dimensional modeling software. However, the cutting method using the two-dimensional drawing tool needs a technician to manually draw a steel bar arrangement drawing and prepare a material list, which is low in efficiency and low in fault tolerance. In addition, hidden design conflicts cannot be found and solved in the modeling stage in advance, and the practicability is poor. The cutting method based on the three-dimensional modeling software is difficult to handle in a nuclear power project due to the complexity of the drawings, the difference in the labeling method, and the frequent conflicts between the steel bars and the modules, so that the conventional three-dimensional modeling software cannot quickly and comprehensively meet the modeling requirements. In addition, the steel bar detail drawing and the cutting list cannot be generated at the same time, and the use effect is poor.
