Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0027] Embodiment 1

[0028] Reference Figure 1 And Figure 4 In order to improve the poor precision of manual installation of U-shaped anchor bolts, an embodiment of the utility model provides a device for improving the positioning precision of the pre-buried bolt of the photovoltaic cast-in-place pile, which comprises a positioning frame 1, a positioning column 2 and four positioning pipes 3. The positioning frame 1 is placed on the pre-buried pipe 4, the positioning column 2 is used for positioning, and the positioning pipe 3 is used for installing the pre-buried bolt 5. The pre-buried bolt 5 is a U-shaped anchor bolt, which facilitates manual operation and installation of the pre-buried bolt 5.

[0029] The middle part of the positioning frame 1 is provided with a pouring hole 11 for pouring. When the conventional pre-buried bolt positioning and fixing device is used, the pouring of the concrete of the photovoltaic cast-in-place pile is often hindered. The utility model avoids hindering the pouring of the concrete and improves the pouring efficiency by designing the pouring hole 11.

[0030] There are at least three positioning posts 2, all of which are fixedly connected to the positioning frame 1. The positioning posts 2 are evenly distributed in a circle; preferably, there are three or four positioning posts 2. Three positioning posts 2 can be distributed in an equilateral triangle, and four positioning posts 2 can be evenly distributed in a circle, with the triangle inscribed in the circle. In use, the positioning frame 1 is placed on the embedded pipe 4, and the outer wall of the positioning post 2 fits against the inner wall of the embedded pipe 4, which can improve the positioning accuracy of the photovoltaic grouting pile embedded bolts.

[0031] The outer walls of the four positioning tubes 3 are fixedly connected to the positioning frame 1. Each pair of positioning tubes 3 forms a group, and the two groups of positioning tubes 3 are distributed on both sides of the positioning frame 1. Each group of positioning tubes 3 is used to install one pre-embedded bolt 5. The pre-embedded bolt 5 is a U-shaped anchor bolt. The two ends of a U-shaped anchor bolt are installed using the two positioning tubes 3 in each group. The four positioning tubes 3 can install two U-shaped anchor bolts.

[0032] Example 2:

[0033] In traditional pre-embedded bolt installation, especially in photovoltaic cast-in-place pile projects, U-shaped anchor bolts require high precision. Particularly during the fixing process, errors in construction operations often lead to misalignment and tilting of the pre-embedded bolts, directly affecting the subsequent installation quality and structural safety. To address this issue, [the following text is missing from the original] Figures 1-4 Based on the above embodiment 1, the positioning frame 1 includes two positioning ears 111, two short sides 112 and two long sides 113; the bottom of each of the two positioning ears 111 is fixedly connected to a positioning post 2; the bottom of each of the two short sides 112 is fixedly connected to a positioning post 2; the two long sides 113 are respectively fixedly connected to the adjacent ends of the two positioning ears 111, and the two long sides 113 and the two short sides 112 are fixedly connected to form a rectangle, and an injection hole 11 is provided in the middle of the rectangle, and the positioning tubes 3 in the same group are all located on one side of the same long side 113.

[0034] By fixing and welding the two positioning ears 111 to the short side 112 and the long side 113, the stability of the structure and the accuracy of the positioning are ensured. The fixed connection between the short side 112 and the long side 113 is precisely controlled. In particular, the design of a 30 cm spacing between adjacent sides of the short side 112 ensures the accuracy of the geometric dimensions of the positioning frame 1, further improving the positioning accuracy of the U-shaped anchor bolts. Through precise dimensional control and stable structural design, the installation accuracy of the pre-embedded bolts is improved.

[0035] The positioning frame 1 is made of angle steel, the positioning column 2 is made of steel bars, the positioning tube 3 is made of steel pipe, and the pre-embedded bolt 5 is a U-shaped anchor bolt. The raw angle steel is cut and welded to form the positioning frame. The positioning column 2 and the positioning tube 3 are then welded to the positioning frame 1. The structure has strong stability, is simple to manufacture, easy to operate, can be reused, and saves costs.

[0036] Embodiment 3:

[0037] With reference to Figures 5-7 In the above embodiment 1, the positioning frame 1 comprises a positioning ring 121 and four positioning ears 111, the bottom of the positioning ring 121 is provided with four positioning columns 2; the four positioning ears 111 are fixedly connected with the positioning ring 121, and the four positioning ears 111 are circularly and uniformly distributed, the positioning ear 111 is composed of an inner ear 123 and an outer ear 122 which is integrally formed with the inner ear 123, the outer ear 122 is located on the outer side of the positioning ring 121, the inner ear 123 is located on the inner side of the positioning ring 121, and one side of one inner ear 123 is fixedly connected to the outer wall of one positioning pipe 3.

[0038] The inner ear 123 is connected with the outer wall of the positioning pipe 3 for mounting and supporting the embedded bolt, the outer ear 122 provides additional support to ensure the stability of the frame and the accuracy of the structure, the positioning ring 121 can reduce the frictional resistance with the embedded pipe 4, and the circular and uniform distribution of the four positioning ears 111 ensures that the entire positioning frame 1 has high symmetry and accuracy during installation, thereby greatly improving the positioning accuracy of the embedded bolt of the photovoltaic cast-in-place pile.

[0039] In another embodiment, the top of one positioning column 2 is fixedly connected to the bottom of one inner ear 123. Each positioning column 2 is connected to the bottom of each inner ear 123, and the four positioning columns 2 can be positioned at the top of the embedded pipe 4 to improve the positioning accuracy of the embedded bolt of the photovoltaic cast-in-place pile.

[0040] In another embodiment, in order to improve the positioning accuracy, the four positioning columns 2 are circularly and uniformly distributed at the bottom of the positioning ring 121. Four points are marked at equal distances on the positioning ring 121, and four positioning columns 2 are fixedly welded respectively, so that the manufacturing process is more convenient and fast, the measurement process is more simple and convenient, and the positioning accuracy is improved.

[0041] In another embodiment, in order to improve the positioning accuracy, the inner diameter of the positioning ring 121 is 30 centimeters, which avoids the inclination or position deviation of the positioning frame and ensures that the position of the embedded bolt remains accurate.
