The lower positioning toothed plate for main reinforcement, the side positioning toothed plate for main reinforcement, and the upper positioning toothed plate for main reinforcement are respectively provided with main reinforcement slots according to the spacing of the main reinforcement of the pier column. The lower positioning toothed plate for stirrups and the side positioning toothed plate for stirrups are respectively provided with stirrup slots according to the spacing of the stirrups of the pier column.

[0006] The frame includes two lower longitudinal bars and two upper longitudinal bars. Multiple vertical bars are welded equidistantly between each lower longitudinal bar and one upper longitudinal bar, and multiple lower horizontal bars are welded equidistantly between the two lower longitudinal bars.

[0007] The main rib lower positioning tooth plate has multiple pieces. Each main rib lower positioning tooth plate is welded to two vertical rods that are opposite each other in the transverse direction along the frame skeleton at both ends. The main rib slot on the main rib lower positioning tooth plate faces upward.

[0008] The main rib has multiple positioning toothed plates. Each main rib positioning toothed plate is connected at both ends to two vertical rods that are opposite to the horizontal direction of the frame frame by bolts. The main rib slot on the main rib positioning toothed plate faces upward.

[0009] A main rib side positioning toothed plate is slidably installed on each of the vertical rods, with the main rib slot on the main rib side positioning toothed plate facing inward;

[0010] The stirrup lower positioning toothed plate consists of multiple pieces. Each stirrup lower positioning toothed plate is welded to each lower horizontal bar in a direction parallel to the lower longitudinal bar. The stirrup slot on the stirrup lower positioning toothed plate faces upward.

[0011] At least two stirrup-side positioning toothed plates are slidably installed on the multiple vertical bars on each side of the frame along a direction parallel to the upper and lower longitudinal bars, with the stirrup slots on each stirrup-side positioning toothed plate facing inward.

[0012] This invention enables the tying of pier column reinforcement in whole segments on the ground, which can reduce construction risks and improve the installation accuracy and construction efficiency of reinforcement. The position of the main reinforcement positioning tooth plate and the stirrup positioning tooth plate can be adjusted to adapt to the cross-sectional changes of the pier column reinforcement cage, thereby realizing standardized and prefabricated construction of pier column reinforcement tying.
