[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1-2The figure shows a cross-sectional schematic diagram of a steel-concrete composite tower in bridge construction. During the design of the steel-concrete composite tower, the transverse reinforcement 400 needs to be located at the center of the vertical rib plate when passing through the vertical rib plate, and the vertical reinforcement 300 needs to be located at a position where the transverse rib hole 101 is away from the outer wall plate 200 when passing through the transverse rib plate 100. In order to realize the design intention, a specific tooling fixture is required during the construction process to position the vertical reinforcement 300 at the side of the transverse rib hole 101 away from the outer wall plate 200, thereby improving the manufacturing accuracy and production efficiency of the steel-concrete composite tower, shortening the production cycle, and saving labor costs.

[0022] Example 1: Please refer to Figures 3 to 5 The vertical steel bar positioning fixture comprises a positioning clamp 1 for abutting against the surface of the transverse rib plate 100. The side of the positioning clamp 1 away from the outer wall plate 200 has a pair of notched grooves 11. The notched grooves 11 are used to clamp against the outer wall of the vertical steel bar 300 and push the vertical steel bar 300 against the inner hole wall of the transverse rib hole 101. The abutment point between the vertical steel bar 300 and the corresponding transverse rib hole 101 is far away from the outer wall plate 200. In order to better cooperate with the vertical steel bar 200, the notched groove 11 has a semicircular groove wall for cooperating with the vertical steel bar 300. Both ends of the positioning clamp 1 are penetrated with outer end fastening components 2. The outer end fastening component 2 is used to fix the positioning clamp 1 and the transverse rib plate 100, and the outer walls of the screws 21 of the two outer end fastening components 2 are abutted against the inner hole walls of the corresponding transverse rib holes 101, wherein the line between the abutment points of the screws 21 and the corresponding transverse rib holes 101 coincides with the center of the two transverse rib holes 101. With such a structural design, the positions of the two screws 21 can be synchronously limited by the two transverse rib holes 101, and the two screws 21 cannot move up and down, and then the screws 21 limit the positioning clamp 1, and the positioning clamp 1 can push the vertical steel bars 300 against the transverse rib holes 101 away from the outer wall plate 200.

[0023] Obviously, the outer end fastening assembly 2 may specifically include a screw 21 and a nut 22. The screw 21 is inserted into the positioning clamp 1. The threaded section of the screw 21 cooperates with the nut 22. The nut end of the screw 21 is abutted against the other surface of the transverse rib plate 100, and the screw 21 may specifically contact the inner hole wall of the transverse rib hole 101 through the smooth rod section.

[0024] Example 2: Please refer to Figure 6 , the vertical steel bar positioning fixture is different from the embodiment 1 in that a pair of positioning clamps 1 are provided, and the two positioning clamps 1 are respectively abutted against the upper surface and the lower surface of the transverse rib 100, and the outer end fastening assembly 2 fastens the two positioning clamps 1 and the transverse rib 100. The two positioning clamps 1 cooperate with the outer end fastening assembly 2, so that the axis of the screw 21 can be kept perpendicular to the transverse rib 100, avoiding the inclination of the screw 21 passing through the single positioning clamp due to its thin thickness, and ensuring the clamping accuracy.

[0025] Example 3: Please refer to Figures 7-8 The vertical steel bar positioning fixture differs from Example 2 in that it also includes a pair of inner end fastening components 3 passed through the positioning clamp 1, the inner end fastening component 3 is located between the two notched grooves 11, and the outer walls of the screws 21 of the two outer end fastening components 2 are also abutted against the inner hole walls of the corresponding transverse rib holes 101. Obviously, the inner end fastening component 3 also includes a screw 21 and a corresponding nut 22. Through the coordinated fastening of the inner end fastening component 3, the clamping and positioning structure between the positioning clamp 1, the transverse rib plate 100 and the vertical steel bar 300 is more stable.
