[0002] Flat construction drawings are a kind of drawing rules that follow the overall plane representation method. The size and reinforcement of structural components are directly expressed on the structural layout plan of the components, and then used in conjunction with standard construction details. Reinforcement detail drawings are a traditional construction drawing expression method, which requires drawing the section, plane and reinforcement detailed drawings of the components. The advantages of flat construction drawings are that the drawings are concise, clear, intuitive, and the number of drawings is small; while reinforcement detail drawings are detailed and can better meet construction requirements.

[0003] At present, design institutes mostly use flat construction drawings during the design stage, which is more suitable for the working habits of designers and is convenient for overall control. However, flat construction drawings need to be used in conjunction with standard drawings, which have high professional requirements for users. In the actual construction process, construction workers are more accustomed to using reinforcement details, because reinforcement details can more intuitively display the section, plane and reinforcement details of the components, which is convenient for construction workers to accurately understand and implement.
