[0030] Embodiment 1:

[0031] Please refer to Figure 1-6 , the present utility model provides a whole production jig for the steel bars of the polygonal variable cross-section inclined tower column parts, including a middle support working platform 1, an inner cavity support working platform 2, a plurality of movable support working platforms 3, a laying board 4, and a positioning system;

[0032] The middle support working platform 1 is arranged at the center of the opposite inclined surfaces of the two columns of the inclined tower column and is arranged along the outer contour of the center of the inclined surface of the inclined tower column;

[0033] A plurality of the movable support working platforms 3 are arranged along the outer contour of the inclined tower column from both sides of the middle support working platform 1 and enclose the polygonal structure of the inclined tower column with the middle support working platform 1. Adjacent movable support working platforms 3 and the joints with the middle support platform are all connected by a bridging plate 4. Any one of the movable support working platforms 3 is moved through a traveling system to adjust the outer cross-sectional dimension of the inclined tower column;

[0034] The inner cavity support working platform 2 is arranged along the inner cavity contour of the inclined tower column. Both the inner cavity support working platform 2 and the middle support working platform 1 are connected with a stiffening skeleton 10 through an adjustable strut 9. The vertical main reinforcement 11 of the inclined tower column is fixedly connected with the stiffening skeleton 10. The adjustable strut 9 is used to adjust the dimensions of the inner contour and the outer contour of the inclined tower column. A herringbone staircase 7 and a cage ladder 8 are respectively arranged on the inner cavity support working platform 2 and the middle support working platform 1;

[0035] The positioning system is used for installing the vertical main reinforcement 11.

[0036] The traveling system includes traveling wheels. The bottom of each movable support working platform 3 is provided with the traveling wheels. The movable support working platform 3 is pushed by the traveling wheels to move along the outer contour of the inclined tower column to adapt to the change of the cross-sectional dimension of the inclined tower column.

[0037] The heights of the middle support working platform 1, the inner cavity support working platform 2 and the movable support working platform 3 are relatively flush with the height of the vertical main reinforcement 11, and all are provided with upper, middle and lower three-layer operation platforms. The adjustable struts 9 connected with the stiffening skeleton 10 are arranged on the upper and middle operation platforms of the middle support working platform 1 and the inner cavity support working platform 2.

[0038] The adjustable strut 9 is a threaded telescopic rod 901 and a sleeve 902. The threaded telescopic rod 901 is movably inserted into the inside of the sleeve 902. The threaded telescopic rod 901 is threadedly connected with an adjusting handle 903. The adjusting handle 903 is rotationally connected with the end of the sleeve 902 sleeving the threaded telescopic rod 901. The sleeve 902 is fixedly connected with the upper and middle operation platforms on the inner cavity support working platform 2 or the middle support working platform 1 through a U-shaped snap ring 904. The threaded telescopic rod 901 is connected with the stiffening skeleton 10.

[0039] On each layer of the operation platforms on the middle support operation platform 1, the inner cavity support operation platform 2, and the movable support operation platform 3, corresponding extended platforms are provided according to the inclination of the vertical main reinforcement 11.

[0040] In this embodiment, during construction, first, the middle support operation platform 1 is installed between the two columns of the inclined tower column. Then, according to the outer contour of the inclined tower column, the movable support operation platform 3 is extended from both sides of the central support operation platform until it encloses a shape consistent with the column shape of the inclined tower column. By setting the middle support operation platform 1, operations can be carried out on the two columns of the inclined tower column simultaneously, thereby improving work efficiency. Connecting the movable support operation platforms 3 of the two columns by the middle support operation platform 1 is beneficial for saving the materials for building the falsework and can also reduce the errors caused by building a single column, thus ensuring the accuracy of building the two opposite columns, improving work efficiency and work quality. And by constructing the two columns simultaneously, the construction resources can be fully utilized, the construction period can be reduced, thereby improving the overall construction efficiency. Also, they can support each other during the construction process, enhancing the overall stability of the structure and reducing the construction risk. When constructing the two columns simultaneously, the positioning and installation accuracy of the falsework can be better controlled, ensuring the tensioning of the prestress and the subsequent stress conditions, thereby improving the quality and lifespan of the structure. Further, a walking system is provided at the bottom of the movable support operation platform 3, which is convenient for moving and adjusting the cross-sectional size outside the tower column. The position between the inner cavity support operation platform 2 and the stiffening skeleton 10 is adjusted through the adjustable strut 9, which is beneficial for adjusting according to the shape change of the inclined tower column, thereby improving the accuracy of building the steel bars of the inclined tower column components. In this embodiment, the adjustable strut 9 is realized by a threaded telescopic rod 901, a sleeve 902, and an adjusting handle 903. By rotating the adjusting handle 903, its horizontal position on the threaded extension rod is adjusted. Since the adjusting handle 903 is movably connected to the sleeve 902, when the adjusting handle 903 moves, it will push the sleeve 902 to move on the threaded telescopic rod 901, thereby realizing the telescoping, which is convenient for adjusting the distance between the inner cavity support or the middle support and the stiffening skeleton 10, can better adapt to steel bar segments of different sizes and shapes, ensure the precise docking and fixation of the steel bar segments, thereby improving the construction accuracy and efficiency, contributing to optimizing the layout of the steel bar segments, making the structure of the tower column more stable, enhancing the overall load-bearing capacity and the anti-weathering and earthquake-resistant performance of the tower column. In addition, appropriate distance adjustment can also reduce the errors during the construction process and reduce the safety hazards caused by inaccurate docking.
