Yes, you can see the section on the binding of steel bars in the technical specifications for the construction of reinforced concrete structures.
Whether it is tying overlapping steel bars or tying at the intersection of vertical and horizontal bars, the purpose is to position the steel bars. The fasteners do not ultimately participate in the stress, but only ensure that the steel bars will not leave their positions during the concrete pouring process. where it should be. Therefore, there is no hard and fast rule in the country that all people must be tied up. There is a possibility that local standards or corporate standards in various places may impose strict requirements.
Although there is no hard and fast rule that it must be fully tied, jump buckle tying has been done for a period of time during construction before, and the effect was not ideal.
Because of the vibration of the vibrator during the concrete pouring process, Due to technical or conscientious reasons, the vibrator rod touches the steel bars. The steel bars that are not fully tied are easier to move than the fully tied steel bars, so try to use full ties. It should be noted that the ligation of vertical and horizontal intersections must use eight-shaped buckles, not all straight buckles, as all straight buckles will also cause the steel bars to move.
