[0001] The utility model relates to the technical field of positioning devices, in particular to a steel bar coaxial positioner. Background Art

[0002] Basically, concrete is arranged inside a steel member in a steel-concrete structure. To improve the strength of the structure, steel bars are also inserted inside the steel member. Usually, rib plates are arranged on the inner side of the steel member, and through holes are formed in the rib plates to facilitate the passing of the steel bars. The size of the through holes in the rib plates is larger than the size of the steel bars. Therefore, after the steel bars pass through the through holes in the rib plates, it is difficult to ensure that the steel bars are coaxial with the centers of the through holes in the rib plates. If the steel bars are not coaxially arranged with the through holes in the rib plates, the docking difficulty between the steel-concrete structures increases, and it is difficult to ensure the docking accuracy. In the prior art, workers usually spot-weld the two ends of the steel bars to the corresponding rib plates, so that when the steel-concrete structures are docked, the steel bars are difficult to be aligned and connected, which in turn affects the structural strength of the steel-concrete structures. Therefore, there is an urgent need to provide a solution for coaxial steel bars. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the defects of the prior art and provide a steel bar coaxial positioner to solve the problem that the positioning of the steel bar perforation cannot be carried out in the prior art, which in turn affects the structural strength of the steel-concrete structure.

Referring to Figure 2, showing a side view of the steel bar coaxial positioner of the present utility model. The following will be combined with Figure 1 and Figure 2 , to describe the steel bar coaxial positioner of the present utility model.

[0036] As shown in Figure 1 and Figure 2 , the steel bar coaxial positioner 20 of the present utility model includes a positioning seat 21, a sliding seat 22 and a fastener 23. A first positioning groove 211 for positioning the steel bar is formed on the positioning seat 21; the sliding seat 22 is slidably arranged on the positioning seat 21, and a second positioning groove 221 for positioning the steel bar is formed on the sliding seat 22. The second positioning groove 221 is arranged corresponding to the first positioning groove 211, and the sizes of the first positioning groove 211 and the second positioning groove 221 are adapted to the size of the steel bar to be positioned; the fastener 23 is connected to the sliding seat 22, and the fastener 23 can be adjusted in position relative to the sliding seat 22. By adjusting the position, the end of the fastener 23 can extend into the second positioning groove 221 to press against the steel bar.

[0052] The steel bar coaxial positioner of the utility model is particularly suitable for the manufacturing process of the steel-concrete composite tower. In the design process of the steel-concrete composite tower, the vertical steel bars are sequentially passed through the mounting holes of the horizontal stiffening ribs, and the horizontal stirrups are sequentially passed through the mounting holes of the vertical stiffening ribs to form reinforced concrete tenons, so as to achieve the synergistic effect of the steel structure and the concrete. When the vertical steel bars pass through the horizontal stiffening ribs, it is necessary to ensure that they are in the center position of the mounting holes of the horizontal stiffening ribs, so that the coaxiality of the two vertical steel bars can ensure the position assembly accuracy of the two steel molds after docking when docking. The steel bar coaxial positioner of the utility model can ensure the positioning accuracy of the steel bars, and it can also clamp the steel bars to ensure that the steel molds will not fall off during the assembly process. When in use, the positioner can be set in the mounting holes of the horizontal stiffening ribs at the two ends of the steel mold. After the steel molds are docked and the connection and fixation of the two vertical steel bars are completed, the positioner can be disassembled for reuse.
