When installing the steel bars, one-side straight buckle method is used to tie them at the intersection of the steel bars. However, in a large-area grid structure, in order to keep them from deforming, the eight-character buckle method can also be used to tie them (fastening them in left and right directions), and the steel wire should be short and firm. Generally, the rotation number of the steel bar hook is 1.5 ~ 2.5 revolutions.
when overlapping and binding, three roads should be tied at both ends and in the middle of the joint.
