In this solution, since both ends of the cable are stretched, the force balance at both ends of the second column at the middle position can be maintained in a vertical installation state, and the tops of the second columns on both sides are installed inclined towards the middle position. When the two ends of the cable are stretched, the tension force of the two ends of the second column on both sides is not equal, so the second column on both sides of the middle position will follow the deformation of the end of the cable with a larger tensile force to swing to a vertical state. Therefore, after the tensioning of the cables is completed, all the second columns are installed vertically to improve the installation accuracy;

When tensioning one end of the cable, the top of the second column is installed obliquely away from the tensioning end of the cable. After the tensioning of one end of the cable is completed, the second column swings to a vertical state following the deformation of the cable. In this scheme, because one end of the cable is stretched, the second column is subjected to tension at one end, and the top of the second column is installed obliquely away from the tension end of the cable. When the tension end of the cable is stretched, the second column is driven The top of the cable deforms and swings toward the tension end of the cable, thereby driving the top of the second column to swing to a vertical state. After the cable tensioning is completed, all the second columns are installed vertically to ensure installation accuracy.

As shown in FIG. 14 , when the bottom of the column 1 is hinged to the foundation 3 , the top of the column 1 is installed obliquely toward one end of the cable 2 , so that the cable 2 is hinged to the tops of multiple columns 1 . At this time, the bottom of the column 1 is hinged with the foundation 3, that is to say, the column 1 can follow the swing of the cable 2 during the tension deformation of the cable 2, so the top of the column 1 is installed obliquely towards one end of the cable 2, so that the cable When the cable 2 is tensioned, the column 1 is driven to swing to a vertical state, thereby improving the vertical installation accuracy of the column 1 . Specifically, when the bottom of the column 1 is hinged to the foundation 3, all the columns 1 are swing columns at this time, the cable 2 is tensioned at one end, and the top of the column 1 is installed obliquely away from the tension end of the cable 2, so that the cable 2. When tensioned, the column 1 is driven to swing to a vertical state.

For example, the inclination of the top of the column 1 is successively L1, L2, ^... , Ln (n is the number of column 1), and the top of the column 1 follows the swing displacement of the cable 2 when one end of the cable 2 is stretched. are -L1, -L2, ^... , -Ln, so that all columns 1 can swing to a vertical state, and complete vertical construction with high precision.

In this solution, since both ends of the cable 2 are stretched, the force balance at both ends of the second column 12 in the middle position can maintain the vertical installation state, and the tops of the second columns 12 on both sides are installed inclined towards the middle position. , when the two ends of the cable 2 are stretched, the tension force on the two ends of the second column 12 on both sides of the cable 2 is not equal, so the second column 12 on both sides of the middle position will follow the cable 2 with a larger tension One end is deformed and swings to a vertical state, so that after the cable tensioning is completed, all the second columns 12 are installed vertically, which improves the installation accuracy;

For example, if the inclination of the top of the second column 12 located on both sides of the middle position is X1, X2, ^... , Xn (n is the quantity of the second column 12 on both sides), the two ends of the dragline 2 When tensioning, the top of the second column 12 follows the swing displacement of the cable 2 to -X1, -X2, ^... , -Xn, so that the second column 12 on both sides swings to a vertical state, ensuring that the first The vertical construction of the two columns 12 has high precision.

As shown in Figures 9 and 11, when tensioning one end of the cable 2, the top of the second column 12 is installed obliquely away from the tensioning end of the cable 2, and the second column 12 is installed after the tensioning of one end of the cable 2 is completed. Follow the deformation of the cable 2 to swing to a vertical state. In this scheme, because one end of the cable 2 is tensioned, the second column 12 is subjected to tension at one end, and the top of the second column 12 is installed obliquely away from the tensioned end of the cable 2. When the two tensioned ends of the cable are stretched At the same time, the top of the second column 12 is driven to deform and swing toward the tension end of the cable 2, thereby driving the top of the second column 12 to swing to a vertical state. After the tension of the cable 2 is completed, all the second columns 12 are realized Install vertically to ensure installation accuracy.

For example, if the inclination of the top of the second column 12 is Z1, Z2, ^... , Zn (n is the quantity of the second column 12), the top of the second column 12 follows when one end of the cable 2 is stretched. The swinging displacements of the cables 2 are -Z1, ^-Z2 , .

It should be noted that the inclinations Ln, Xn and Zn of this embodiment are related to the length of the column 1, the diameter of the dragline 2, etc., and the elongation Ln, Xn and Zn can be simulated through variable calculation or in software. Zn, the specific calculation method and simulation method are well-known technologies in the art, and will not be repeated in this embodiment.

As shown in Fig. 5, Fig. 6, Fig. 9 to Fig. 12, Fig. 14, and Fig. 15, specifically, tensioning the cable 2 includes: stretching one or both ends of the cable 2 for the first time, The tension of the first tension is less than the preset value, the photovoltaic module 10 is installed on the cable 2, and one or both ends of the cable 2 are stretched for the second time, and the tension of the second tension reaches the preset value. set value.

In this solution, the cable 2 is stretched twice, the first stretching facilitates the initial formation of the photovoltaic support structure, and then the photovoltaic module 10 is installed on the cable 2, and the second stretching adjustment is performed on the cable 2 and The tension reaches the preset value and the designed deformation state, and the construction is completed. Compared with one-time stretching and forming, the cable 2 of this embodiment is stretched in two times to facilitate the structural offset or The deformation is adjusted to improve the construction accuracy of the entire photovoltaic support.

Further, the tension of the first tension is 50% or 70% of the preset value. Specifically, as shown in Figure 5, Figure 6, Figure 9 to Figure 12, when the bottom of the column 1 is fixedly connected with the foundation 3 or only the bottom of the second column 12 is hinged with the foundation 3, the cable 2 is tensioned for the first time If the tensile force is 50% of the preset value, the photovoltaic support can be formed stably; as shown in Figure 14 and Figure 15, when the bottom of the column 1 is hinged with the foundation 3, that is, the column 1 is a swing column, and the cable 2 The tension force of the first tension is 70% of the preset value, so that the cable 2 can provide enough tension force to stably form the photovoltaic support.

Anchor both ends of the cable 2 to the foundation 3. Specifically, as shown in FIG. 6 , FIG. 12 and FIG. 15 , when the cable 2 is tensioned, both ends of the cable 2 are anchored to the foundation 3 to realize fixing and ensure the structural stability of the entire photovoltaic support.

It should be noted that the foundation 3 in this embodiment can be the ground, or a concrete layer poured separately.

Apparently, the above-mentioned embodiments are only examples for clear description, rather than limiting the implementation. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. It is not necessary and impossible to exhaustively list all the implementation manners here. And the obvious changes or changes derived therefrom are still within the scope of protection of the present invention.
