Its support columns usually adopt the form of cast-in-place reinforced concrete pile foundations with embedded stainless steel columns. Generally, the stainless steel column is 1850mm long and weighs 17.75kg. The embedded depth of the column is ≥500mm, and the exposed part of the column is about 1350mm long. The conventional support column embedded construction technology is to use wooden formwork to support the formwork, and use square wood and scaffolding to fix the formwork and steel pipe columns. This method often has the following shortcomings: 1. The material consumption is large, the device is large, heavy and easy to be damaged; 2.

It is easy to cause the embedded column to shift eccentricity during concrete pouring and vibration, and the verticality of the column cannot be guaranteed, which is easy to produce unqualified products.

DETAILED DESCRIPTION
[0019] like Figures 1 to 3 As shown, the utility model is a pre-embedded fixing device for a mountain photovoltaic support column, comprising a circular template clamp 1, a column clamp 2, a fixing bolt 5, a fixing nut 13, a rotating screw 9 and a rotating adjustment rod 10.
[0020] like Figure 1 , Figure 2 As shown, the circular template hoop 1 is used to fix the concrete pile circular template 14, and the column hoop 2 is used to fix the embedded column 15. The open ends of the circular template hoop 1 and the column hoop 2 can be connected and fixed by fixing bolts 5, respectively. One end of the fixing bolt 5 cooperates with the fixing nut 13 to lock the hoop. The inner diameter of the circular template hoop 1 is equal to the outer diameter of the cast circular template, and the inner diameter of the column hoop 2 is equal to the outer diameter of the embedded column 15. The outer circumferential surface of the circular template hoop 1 is connected with circular template hoop fixing plates 7 with equal intervals, and each circular template hoop fixing plate 7 is provided with a connecting hole Ⅰ8. The column hoop 2 is located above the circular template hoop 1, and the outer circumferential surface of the column hoop 2 is connected with column hoop fixing plates 3 with equal intervals. The column hoop fixing plates 3 are respectively located directly above the circular template hoop fixing plates 7, and each column hoop fixing plate 3 is provided with a connecting hole Ⅱ4 corresponding to the position of the connecting hole Ⅰ8, and the upper surface of the column hoop fixing plate 3 is connected with a reinforcing rib 6. In this embodiment, the outer circumferential surface of the circular template hoop 1 is connected with three circular template hoop fixing plates 7 arranged at intervals, the angle between adjacent circular template hoop fixing plates 7 is 120 degrees, and each circular template hoop fixing plate 7 is provided with a connecting hole Ⅰ8. The outer circumferential surface of the column hoop 2 is connected with three column hoop fixing plates 3 arranged at intervals, the angle between adjacent column hoop fixing plates 3 is 120 degrees, the three column hoop fixing plates 3 are respectively located directly above the three circular template hoop fixing plates 7, and the three connecting holes Ⅱ4 are respectively arranged above the three connecting holes Ⅰ8. The connecting hole Ⅱ4 on the column hoop fixing plate 3 is an elongated connecting hole (elliptical elongated hole), and the position of the rotating screw 9 can be fine-tuned when the rotating screw 9 is positioned in the elongated connecting hole Ⅱ4.
[0021] like Figure 3As shown, the rotating screw rod 9 is connected between the column clamp fixing plate 3 and the circular template clamp fixing plate 7 which are in corresponding positions, and three rotating screw rods 9 are respectively connected between the three circular template clamp fixing plates 7 and the three column clamp fixing plates 3, and the upper end of each rotating screw rod 9 passes through the connecting hole II4 and is connected to a fixing nut 13, and the lower end of the rotating screw rod 9 passes through the connecting hole I8 and is connected to another fixing nut 13.
[0022] like Figure 3 As shown, the rotary adjustment rod 10 is sleeved outside the rotary screw 9, and the rotary adjustment rod 10 includes a steel pipe 12 passing through both ends and nuts 11 connected to the ends of the steel pipe 12. The outer surface of each rotary screw 9 is sleeved with a rotary adjustment rod 10. The steel pipe 12 is made of a φ25 galvanized steel pipe, and the two ends of the steel pipe 12 are respectively connected to the nuts 11 by welding. The rotary adjustment rod 10 is sleeved on the rotary screw 9 as a whole, and the internal threads of the nuts 11 at the upper and lower ends of the rotary adjustment rod 10 cooperate with the external threads of the rotary screw 9. Rotating the rotary adjustment rod 10 can adjust the position of the rotary screw 9 in the vertical direction and thus adjust the position of the column clamp 2. Specifically: when the rotating adjustment rod 10 outside a certain rotating screw 9 is rotated, the rotating screw 9 inside the rotating adjustment rod 10 can move up or down in the vertical direction. Therefore, the vertical position of the rotating screw 9 can be adjusted by rotating the rotating adjustment rod 10. The rotating screw 9 pulls the column clamp fixing plate 3 connected to it to swing up and down, and the column clamp fixing plate 3 pulls the column clamp 2 connected to it to deflect up and down, so as to adjust the verticality of the embedded column 15 inside the column clamp 2.
[0023] For the implementation process, please also refer to Figure 4 As shown, firstly, the circular formwork clamp 1 is fixed to the upper end of the concrete pile circular formwork 14 by using the fixing bolts 5, the two end openings of the rotating adjustment rod 10 are respectively welded to the nuts 11, one end of the rotating screw 9 is respectively inserted into the rotating adjustment rod 10, the lower end of the rotating screw 9 is inserted into the circular formwork clamp fixing plate 7 and fixed with the fixing bolt 5, the column clamp 2 is put on the embedded column 15, the elliptical long hole of the column clamp fixing plate 3 is inserted into the upper end of the rotating screw 9 and positioned with the fixing nut 13. By fine-tuning the position of the rotating screw 9 in the elliptical long hole (connecting hole II4) of the column clamp fixing plate 3, the concentricity of the embedded column 15 and the concrete pile can be adjusted. By rotating the rotating adjustment rod 10, the verticality of the embedded column 15 can be adjusted to achieve the verticality of the embedded column 15 to meet the design requirements. As shown Figure 4In the figure, for the convenience of explanation, the three rotating adjustment rods are respectively marked as rotating adjustment rod A, rotating adjustment rod B, and rotating adjustment rod C. When it is found that the embedded column 15 is biased to the left, that is, the right side of the column clamp 2 outside the embedded column 15 is too high, the rotating adjustment rod C on the right side can be rotated to make the rotating screw 9 inside the rotating adjustment rod C slightly move downward as a whole, and the column clamp fixing plate 3 connected to the rotating screw 9 inside the rotating adjustment rod C (that is, the column clamp fixing plate on the right side) is pulled downward for a displacement, and the column clamp fixing plate 3 on the right side pulls the right side of the column clamp 2 to make the column clamp 2 slightly deflected to the lower right side until the column clamp 2 reaches a flat position on the left and right. At this time, the embedded column 15 is in a vertical position, and the rotation of the rotating adjustment rod C is stopped to complete the adjustment of the verticality of the embedded column 15. Of course, it is not limited to rotating one rotating adjustment rod, and the rotating adjustment rod B and the rotating adjustment rod C can also be adjusted at the same time, or the rotating adjustment rod C can be mainly adjusted and the rotating adjustment rod B can be fine-tuned, as long as the column clamp 2 can be adjusted to the same horizontal position on the left and right sides. Therefore, by adjusting 1-2 rotating adjustment rods 10, the position of 1-2 rotating screws 9 can be changed to adjust the uneven column clamp 2 to a flat state, and the vertical adjustment of the embedded column 15 can be completed to meet the design requirements. During construction, one or two rotating adjustment rods can be flexibly selected to rotate according to the deviation of the column clamp 2 to adjust the position of the column clamp 2.

Any modifications, equivalent substitutions, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
