Rebar turning sample refers to the construction technicians according to the drawings to calculate the quantity of the detailed processing list and draw the rebar processing sample sketch, turning sample in the past or today is a cumbersome, difficult technical mental labor. The calculation process is complex and cumbersome, requiring rich construction experience, accuracy, rationality and optimization, understanding norms, understanding atlas, understanding drawings, and difficult higher technical occupations. In the practical application process, it is divided into two categories, one is the budget sample, which refers to the steel bar sample of the drawing in the design and budget stage to calculate the content of steel bars in the drawing, for the steel bar cost budget, bidding work, steel bar settlement, etc. The function of rebar flipping mainly includes ensuring the strength and stability of the structure, improving the construction efficiency and construction quality, and avoiding the quality problems of rebar flipping, analyzing the basis of rebar flipping and the thinking of rebar flipping, combining with the examples of rebar flipping, analyzing the rebar flipping technology, optimizing the rebar flipping results, and carrying out the ingredients of the flipping results. This paper describes the application of rebar turning technique in the control of rebar loss rate and construction organization [6].
