the conveying robot conveys the bottom web stirrup to one end of the guide rail of the storage area;
the placing device clamps the bottom web stirrups, so that the upper ends of the two web stirrups of the bottom web stirrups are aligned to the supporting beam;
the placing device moves along the length direction of the supporting beam, the upper ends of the two web stirrups are respectively sleeved on the two supporting beams, and the placing device sequentially hangs the plurality of web stirrups on the supporting beam along the length direction of the supporting beam;
after all web stirrups of little case roof beam hang and establish on the supporting beam, electronic removal cushion cap removes to the other end of guide rail is so that ligature little case roof beam's steel bar structure.
