Precise construction method for ring beam steel bars of large concrete filled steel tubular column with shear rings

The invention discloses a precise construction method for ring beam steel bars of a large concrete filled steel tubular column with shear rings. The precise construction method comprises the followingsteps that S1, the steel bars are cut according to a design drawing of the ring beam steel bars, and the steel bars are cut off according to a set length; S2, stirrups in the ring beam steel bars aremachined and formed through a hoop bending machine, and longitudinal circular ring steel bars in the ring beam steel bars are machined and formed through a numerical control steel bar arc bending machine GWH-40; S3, shape inspection, fine adjustment, correction and connector welding are carried out on the longitudinal circular ring steel bars in an inspection and correction device; S4, supports are manufactured and placed in a cross shape, and steel pipes are transversely erected on the supports according to the positions of the longitudinal circular steel bars in the drawing; S5, scribing iscarried out on the placeme
