6. A method of machining a web stirrup at the bottom of a small box girder in a web stirrup machining system at the bottom of a small box girder as claimed in any one of claims 1 to 5, comprising the steps of:
inputting the steel bars into a numerical control hoop bending machine, wherein the steel bars are bent and formed by the output of the numerical control hoop bending machine;
the grabbing robot grabs the bent steel bars and places the steel bars on a welding table;
the welding robot welds the bent and formed steel bars into a three-in-one bottom web stirrup;
the conveying robot conveys the three-in-one bottom web stirrups to one end of a guide rail of a storage area;
the placing device clamps the three-in-one bottom web stirrup, so that the upper ends of the two web stirrups of the three-in-one bottom web stirrup are aligned to the supporting beam;
the placing device moves along the length direction of the supporting beams, the upper ends of the two web stirrups are respectively sleeved on the two supporting beams, and the placing device sequentially hangs the web stirrups on the supporting beams along the length direction of the supporting beams and is placed on the electric moving bearing platform;
after all web stirrups of the small box girder are hung on the supporting girder, the electric movable bearing platform moves to the other end of the guide rail so as to be convenient for binding the reinforcing steel bar structure of the small box girder.
