The staff uses a measuring tool to measure the installation position of the longitudinal steel bars, and then fixes the longitudinal steel bars on the transverse steel frame by wire tying. However, this operation method will cause the following problems. When installing a large number of longitudinal steel bars, the staff needs to use a tape measure to measure the installation position of each longitudinal steel bar.
