[0040] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0041] like Figures 1-4 As shown, this embodiment provides a threaded steel bar positioning device. The device is used to position 12 threaded steel bars 8 extending along the Z-axis. The 12 threaded steel bars 8 are divided into two groups, each group including 6 threaded steel bars 8 spaced apart along the X-axis. The two groups of threaded steel bars 8 are arranged parallel and spaced apart along the Y-axis, and the X-axis, Y-axis, and Z-axis are perpendicular to each other. The threaded steel bar positioning device is used for stress tensioning operations, and the Z-axis prestressing system of the main pier box girder uses φ32mm standard strength 785Mpa precision-rolled threaded steel bars 8. In other embodiments, the number of threaded steel bars 8 can be adjusted as needed, and is not limited to 12, nor is the number of groups limited to 2.

[0042] The threaded steel positioning device includes a first positioning device and a second positioning device.

[0043] The first positioning device is used to position the threaded steel bar 8 along the X-axis direction. The first positioning device includes two sets of first positioning components that are arranged parallel to each other along the Y-axis direction. Each set of first positioning components includes two first adjusting rods 1 that extend along the X-axis direction and are arranged parallel to each other along the Y-axis direction.

[0044] The second positioning device is used to position the threaded steel bar 8 along the Y-axis. The second positioning device includes six sets of second positioning components arranged parallel and spaced apart along the X-axis. The six sets of second positioning components are divided into two end second positioning components and four intermediate second positioning components. The two end second positioning components are located at the two ends of the four first adjusting rods 1 of the two sets of first positioning components, and each end second positioning component includes two second adjusting rods 2 arranged parallel and spaced apart along the Z-axis. The four intermediate second positioning components are located between the two end second positioning components. Each of the four intermediate second positioning components includes four second adjusting rods 2, which are divided along the Z-axis into two upper second adjusting rods 2 and two lower second adjusting rods 2. The two upper second adjusting rods 2 are arranged parallel and spaced apart along the X-axis, and the two lower second adjusting rods 2 are also arranged parallel and spaced apart along the X-axis.

[0045] The four first adjusting rods 1 of the two groups pass through the gap between the two second adjusting rods 2 of the six groups of the second positioning assembly and are clamped by the two second adjusting rods 2. The junction of the first adjusting rods 1 and the second adjusting rods 2 forms 12 positioning holes for the threaded steel 8 to pass through.

[0046] The two parallel and spaced first adjusting rods 1 are each provided with six first adjusting components. The first adjusting components are used to abut against the second adjusting rod 2 to position the threaded steel 8 in the positioning hole along the X-axis direction.

[0047] The second adjusting rod 2 is provided with two second adjusting components. The second adjusting components are used to abut against the first adjusting rod 1 to position the threaded steel 8 in the positioning hole along the Y-axis direction.

[0048] Specifically, 12 positioning holes simultaneously fix 12 threaded steel bars 8, and the third adjusting nut 9 provides a limit to prevent the first and second positioning devices from sliding down along the threaded steel bars 8. Based on the steel bar dimensions and layout plan, the distance between the threaded steel bars 8 in the X-axis direction is adjusted and positioned by rotating multiple first adjusting components on the first positioning device. Then, the distance between the threaded steel bars 8 in the Y-axis direction is adjusted and positioned by rotating multiple second adjusting components on the second positioning device. Finally, a standardized positioning device is formed.

[0049] In the above structure, a first positioning device is installed to control the X-axis direction of the 12 threaded steel bars 8, and a second positioning device is installed to control the Y-axis direction of the 12 threaded steel bars 8, thus forming a standardized positioning device. This positioning device can be removed and installed as a whole, avoiding repeated disassembly and assembly, saving installation and removal time, and improving installation efficiency. When the positioning spacing of the threaded steel bars 8 changes, only minor adjustments to the positioning device are needed, improving applicability. This threaded steel bar positioning device adopts a non-welded structure, is easy to disassemble and assemble, and can be reused in multiple projects, improving versatility.

[0050] like Figures 1-2 As shown, in a preferred embodiment, the threaded steel positioning device comprises six sets of second positioning components, divided into two end second positioning components and four intermediate second positioning components. The two end second positioning components are respectively located near or at the two ends of the first adjusting rod 1, and the intermediate second positioning components are located between the two end second positioning components. The end second positioning components include two second adjusting rods 2 arranged parallel to each other in the Z-axis direction.

[0051] Each of the four intermediate second positioning components includes four second adjusting rods 2. The four second adjusting rods 2 are divided into two upper second adjusting rods 2 and two lower second adjusting rods 2 in the Z-axis direction. The two upper second adjusting rods 2 are arranged parallel and spaced apart in the X-axis direction, and the two lower second adjusting rods 2 are arranged parallel and spaced apart in the X-axis direction. The two first adjusting rods 1 in each group pass through the gap between the two upper second adjusting rods 2 and the two lower second adjusting rods 2.

[0052] After the X-axis positioning of the threaded steel bar 8 is completed, first adjust the second adjustment components on the four second adjustment rods 2 of the four intermediate second positioning components to adjust and position the threaded steel bar 8 in the positioning hole, and then adjust the second adjustment components on the two second adjustment rods 2 of the two end second positioning components to adjust and position the threaded steel bar 8 in the Y-axis direction.

[0053] By employing two end second positioning components and several intermediate second positioning components, precise control of multiple threaded steel bars 8 in the Y-axis direction is achieved, while also saving material costs.

[0054] like Figures 2-4 As shown, in a preferred embodiment, the threaded steel positioning device includes two first adjusting nuts 7 and a first positioning plate 5 on each first adjusting rod 1 located at the end of the second positioning assembly. The two first adjusting nuts 7 are threadedly connected to the first adjusting rod 1 and are located on both sides of the end of the second positioning assembly. The first positioning plate 5 is sleeved on the first adjusting rod 1 and located between the end of the second positioning assembly and the outer first adjusting nut 7. The threaded steel 8 passes through the positioning hole at the end. The inner first adjusting nut 7 can be adjusted first, followed by the outer first adjusting nut 7. The outer first adjusting nut 7 pushes the first positioning plate 5 towards the inner first adjusting nut 7, allowing the threaded steel 8 to move in the X-axis direction. Finally, the outer first adjusting nut 7 locks the first positioning plate 5 to one side of the threaded steel 8, achieving adjustment of the threaded steel 8 in the X-axis direction. The first positioning plate 5 not only positions the threaded steel 8 but also ensures the minimum interval between the two first adjusting rods 1 of the first positioning assembly.

[0055] The first adjusting component on each first adjusting rod 1 at the middle second positioning component includes two first adjusting nuts 7, which are threadedly connected to the first adjusting rod 1 and located on both sides of the middle second positioning component. A threaded steel bar 8 passes through a positioning hole other than the end positioning hole. The two first adjusting nuts 7 cooperate to move and lock the second positioning component along the X-axis, thereby adjusting and positioning the threaded steel bar 8 in the positioning hole in the X-axis direction.

[0056] The first adjusting component enables precise control of the threaded steel bar along the 8X axis, while also improving adjustment efficiency. The first adjusting nut 7 allows for quick installation and efficient removal, facilitating reuse.

[0057] like Figures 2-4As shown, in a preferred embodiment, the threaded steel positioning device includes two second adjusting nuts 6 and two second positioning plates 3 and 4 on each second adjusting rod 2 located at the positioning hole. The two second adjusting nuts 6 are threadedly connected to the second adjusting rod 2 and are respectively located on both sides of the corresponding positioning hole. Each second positioning plate 3 and 4 is sleeved on the first adjusting rod 1 and is abutted by one second adjusting nut 6 to abut against one first adjusting rod 1. When the threaded steel 8 is located in the positioning hole, the second adjusting nut 6 located inside the positioning hole can be rotated first, and then the second adjusting nut 6 located outside the positioning hole can be rotated. The second adjusting nut on the outside drives the second positioning plates 3 and 4 to push the two first adjusting rods 1 of the first positioning assembly to move the threaded steel 8 along the Y-axis direction. After adjustment, the second adjusting nuts 6 on both sides of the positioning hole are locked.

[0058] The second adjustment component enables precise control and bidirectional stable clamping of the threaded steel bar 8 along the Y-axis, ensuring the perpendicularity and axial consistency of the threaded steel bar 8, while also improving adjustment efficiency. The second adjustment nut 6 allows for quick installation and efficient removal, increasing reusability.

[0059] like Figure 3 and Figure 4 As shown, in a preferred embodiment, in the threaded steel positioning device, the four adjacent second positioning plates 3 on the same side of each positioning hole on the four second adjusting rods 2 of the intermediate second positioning component are connected and form an integral structure. Rotating the four second adjusting nuts 6 simultaneously pushes the integrally structured second positioning plates 3, causing the first adjusting rod 1 to move. This arrangement further improves the adjustment efficiency of the four second adjusting nuts 6 in the Y-axis direction of the threaded steel 8, while also improving the stability of the positioning and clamping.

[0060] like Figure 1 As shown, in a preferred embodiment, the threaded steel bar positioning device includes a third adjusting nut 9 on each threaded steel bar 8. The third adjusting nut 9 is located below each positioning hole and threadedly connected to the threaded steel bar 8. The third adjusting nut 9 abuts against the first adjusting rod 1 and / or the second adjusting rod 2 at the corresponding positioning hole to prevent the first adjusting rod 1 and the second adjusting rod 2 from sliding down along the Z-axis. This third adjusting nut 9 not only adjusts the height of the threaded steel bar 8 in the positioning hole but also prevents the first adjusting rod 1 and the second adjusting rod 2 from sliding down along the Z-axis.

[0061] like Figure 1As shown, in a preferred embodiment, both the first adjusting rod 1 and the second adjusting rod 2 in the threaded steel positioning device are reinforcing bars. The first adjusting rod 1 is a φ12mm reinforcing bar. The components of the threaded steel positioning device can be made of high-strength steel or other bridge-grade materials. This design further improves the structural stability and the versatility of the positioning device.

[0062] like Figure 1 As shown, in a preferred embodiment, in the threaded steel positioning device, multiple threaded steel bars 8 in each group are equally spaced along the X-axis, and multiple groups of threaded steel bars 8 are equally spaced in parallel along the Y-axis. This arrangement ensures that the multiple threaded steel bars 8 are arranged in an array, guaranteeing reasonable stress distribution and improving construction efficiency and structural stability.

[0063] like Figure 1 As shown, in a preferred embodiment, in the threaded steel positioning device, the two first adjusting rods 1 of each group of the first positioning components are arranged at equal intervals along the Y-axis. This arrangement further ensures that the threaded steel bars 8 are positioned along the array, improving construction efficiency and accuracy, and ensuring structural stability.

[0064] like Figure 1 As shown, in a preferred embodiment, in the threaded steel positioning device, the two second adjusting rods 2 of each group of the second positioning components are arranged at equal and parallel intervals in the Z-axis direction. This arrangement ensures structural consistency and standardization.

[0065] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
