[0002] At present, the binding and positioning of the prefabricated steel skeleton of the integral cylindrical concrete wind tower for construction is done by assembling and forming with dispersed positioning brackets before binding. After binding and forming, the frame is manually disassembled before the steel skeleton can be lifted and transported to the next workstation. This method of assembling and disassembling the positioning brackets relies entirely on the operators to install, position and disassemble. The installation accuracy depends on the technical proficiency of the operators. In addition, it is difficult to coordinate the machine with manual correction and positioning, which consumes labor and auxiliary time and has low construction efficiency. It is impossible to quickly correct and position the prefabricated steel skeleton during the installation process of binding and positioning, which ultimately leads to increased construction costs. During the use of the existing installation and positioning tools for prefabricated composite beams, the positioning bracket position needs to be repeatedly adjusted and fixed before the steel skeleton is tied, and manual adjustment consumes manpower, takes a long time to adjust, and the positioning operation is inefficient, resulting in poor use effect.

[0027] like Figure 1 , 3 , 5, and 6, each horizontal channel steel bottom frame 11 is provided with a rotatable bracket part 2, and the rotatable bracket part 2 is welded by a horizontal channel steel bottom plate 21 and a vertical rectangular tube 22 to form a right-angle structure. A horizontal channel steel bottom plate 21 is provided in the slide groove 12 of each horizontal channel steel bottom frame 11, and the vertical rectangular tube 22 faces the direction of the base center column 13, and the vertical rectangular tube 22 is a circular structure around the base center column 13; the positioning shaft 5 is arranged at the corner of the rotatable bracket part 2, and the two ends of the positioning shaft 5 It is installed on the horizontal channel steel bottom frame 11, so that the rotatable bracket part 2 forms a rotatable bracket part, and the rotatable bracket part is fixed by manual operation; when tying the steel bars, the vertical rectangular tube 22 is in a vertical state, and the vertical rectangular tube 22 serves as a supporting frame for tying, and the positioning block 7 on the vertical rectangular tube 22 realizes the positioning of the steel bars; after the tying is completed, the rotatable bracket part 2 is manually rotated around the positioning shaft 5, and the horizontal channel steel bottom plate 21 is tilted toward the center column 13 of the base, so as to facilitate the lifting of the annular steel bars.

[0028] A positioning block 7 is provided on the vertical rectangular tube 22. The positioning block 7 may be an adjustable structure. The positioning block 7 may be fixed to the vertical rectangular tube 22 by screws to adjust the height, thereby satisfying the fixation of horizontal ribs with different spacings.

[0029] A positioning lock 6 is provided at the outer end of the horizontal channel steel bottom frame 11, and the positioning lock 6 fixes the outer end of the vertical rectangular tube 22. The positioning lock 6 can be a pressure block fixed to the horizontal channel steel bottom frame 11 by bolts.
