After welding is completed, the steel cage is rotated, the welded longitudinal bars are clamped on the steel cage placement frame 6, and the next longitudinal bar is placed in the longitudinal bar placement grooves 11, and welded with the ring bars until all the longitudinal bars are welded. The utility model does not require manual alignment of each steel bar by the staff during installation, and it is not easy to shake and shift during the welding process, which simplifies the operation of the steel cage welding process, improves efficiency and saves time.

[0032] Further, refer to Figure 1 , Figure 4 , Figure 5 , Figure 6, a first through hole 9 for the cross bar 4 to pass through is provided at the bottom of the steel bar stopper 5, and the steel bar stopper 5 is fixed by a first fastening nut 10. A second through hole 12 for the cross bar 4 to pass through is provided at the bottom of the steel bar cage placement frame 6, and the steel bar cage placement frame 6 is fixed by a second fastening nut 13. A telescopic sleeve rod 14 is provided at the top of the steel bar cage placement frame 6, and the position of the telescopic sleeve rod is fixed by adjusting the nut 15. A longitudinal reinforcement positioning groove 16 for positioning the longitudinal reinforcement and a ring reinforcement positioning groove 17 for positioning the ring reinforcement are provided on the upper surface of the telescopic sleeve rod 14, and the longitudinal reinforcement positioning groove 16 is orthogonal to the ring reinforcement positioning groove 17. The telescopic sleeve rod 14 is higher than the longitudinal reinforcement placement groove 11. A scale (not shown in the figure) is provided on the cross bar 4. When the ring reinforcement is embedded in the ring reinforcement positioning groove 17 on the steel bar cage placement frame, the ring reinforcement is located on one side of the steel bar stopper 5 and does not abut against the steel bar stopper 5, so that the steel bar stopper 5 maintains a certain distance from the welding point, and the steel bar stopper 5 will not affect the welding operation.

[0033] When in use, multiple steel bar stoppers 5 are adjusted to the same scale through the scale on the cross bar 4.
