The method for binding the reinforcing steel bars is various, and the common reinforcing steel bar binding method comprises a sequential buckling method, a sleeve buckling method, a pocket buckling method, a cross buckling method, a reverse cross winding buckling method, a pocket buckling and winding method and the like. The sequential buckling method is most commonly used, and can be used for plane and vertical face components, such as a bottom plate, a top plate, a wall body and the like, and the sequential buckling cannot be performed all the time when binding is performed, and positive and negative splayed buckles are needed to be adopted at intervals. The snap-on method is mainly used for corner portions of the horizontal bars 16 and the stirrups. The buckle can be used for a plane and can also be used for the junction of the horizontal rib 16 and the bending part of the reinforcing steel bar. The winding method is to prevent the steel bar from sliding or falling off, and the winding direction can be determined according to the possible movement of the steel bar when the steel bar is wound, and the winding method can be used for the vertical part of the horizontal bar 16 and the stirrup. The winding buckle can be realized by combining a cross buckle, an inverse cross buckle, a pocket buckle and the like. The cross-button method and the inverse cross-button method are used in places where relatively firm and strong are required.

The sequential buckling method comprises the following steps: 1) Firstly, folding the cut small strand binding wire in half; 2) During binding, inserting a binding wire into a binding point, and bending upwards by 90 degrees at the crossing position of the reinforcing steel bars; 3) The hook hooks the screw thread, and the screw thread rotates for 2 to 3 circles, so that binding of one node is completed; 4) After binding is completed, pressing the redundant binding wires inwards; 5) The screw thread of each binding point can not follow one direction, and the positive and negative splayed buckles are adopted, so that the bound reinforcing steel bar net has good integrity and is not easy to deform.

2) The method for sleeving and buckling comprises the following steps: 1) Firstly, folding the cut small strand binding wire in half; 2) During binding, the two ends of the binding wire are sleeved on the stirrup and penetrate out from the bottom of the horizontal bar 16; 3) The left hand holds the two ends of the tie wire to bend 90 degrees; 4) Hooking the binding wire from the bottom by using a wire hooking hook, and rotating for 2-3 circles; 5) After binding is completed, the redundant binding wires are pressed inwards.
