In fact, the process of steel bar turnover is that when the construction technicians calculate the quantity according to the drawings, they list the detailed steel bar processing list and draw the processing diagram. The specific situation of this practice is divided into two types:

1, budget double sample

Refers to the steel bar template in the design and budget stage, so as to calculate the content of steel bars in the drawings, which is used for the steel bar cost budget and bidding.

2, the construction of double sample

Specification, shape, size, quantity, weight, etc. In the process of construction, the number of steel members in reinforced concrete structure is listed in detail according to the drawings, and the bill of materials of steel members is formed, which is an effective basis for steel workers to make and tie and install steel members according to the bill of materials.

Relevant requirements of steel bar sample turning

1, which requires accurate calculation and conforms to the design and specifications. In addition to having certain mathematical knowledge and CAD foundation, we should be proficient in drawings, have a deep understanding of design intent and have a certain spatial imagination by using steel bar sampling software to calculate steel bars.

2, requirements conform to the actual construction, guidance and convenient construction. This requires familiarity with the construction site, rich perceptual knowledge and on-site practical experience. After all, it is quite obvious that practice produces true knowledge.

3. The requirements are reasonable. Not only can we find unreasonable places on the drawings and optimize them, so that the model room can be convenient for construction and conform to the specifications, but also can save steel bars as much as possible, which is inseparable from long-term experience, technical accumulation and wisdom.
