Since it is formed by the dimension member 5B, the second short dimension member 5C, and the third short dimension member 5D, the number of the foundation piles 3 and the long dimension members 5B and the head of the foundation pile 3 By increasing the number of joist members 4 etc. that are arranged, in other words, without adding another kind of member, the size in the left-right direction of the solar panel mount can be increased, and solar that is required to be arranged Since a solar panel mount having any left and right dimensions corresponding to the number of panels can be manufactured, the solar panel according to this embodiment is used for a mega solar system for large-scale power generation. It can be applied to the frame.

  In order to install the solar panel mount of the present embodiment on the sloping ground 2 in FIG. 2, as described above, the ground surface 2A is first slanted on the ground surface 2A on which the sloping ground 2 is slanted. The wick L extending in the direction is displayed by ink-drawing work, etc., and then at each position according to the wick L, the foundation piles 3 are separated from each other in the ground 2B of the inclined ground 2 with the same interval in the left-right direction. After that, the head member 6 is coupled to the heads of the respective foundation piles 3 having the same vertical length exposed from the ground surface 2A with the fasteners 7 after that. Next, the joist member 4 is attached to each head member 6 by the bracket member 9, the fastener 10 and the fastener 11, and the first short dimension member of the beam member 5 is attached to the joist member 4 by the bracket member 16 and the fastener 17. 5A is coupled to the first short dimension member 5A, and the long dimension member 5B, the second short dimension member 5C, and the third short dimension member 5D are coupled to each other with the fastener 12, so that the joists are placed on the joist members 4. A beam member 5 that forms an angle with the member 4 is formed.

  Moreover, the work which bridges the cane member 20 between each foundation pile 3 and the joist member 4 is performed, and by performing this work, the ground surface 2A of the slope 2 is inclined. Even if it is one in the direction that forms an angle with the direction in which it is located, the cane that extends from the foundation pile 3 in a direction that forms an angle with the direction in which the ground surface 2A is inclined, that is, obliquely upward in the front-rear direction The base frame 1 can be effectively supported by the member 20.

  As described above, since the solar panel mount according to the present embodiment is installed on the sloping ground 2, as described above, the ground surface 2 </ b> A tilting the front side 1 </ b> A and the back side 1 </ b> B of the base frame 1. Must be parallel or substantially parallel, that is, at an inclination angle corresponding to the inclination of the inclined land 2. However, each foundation pile 3 must be driven vertically or substantially vertically into the sloped land 2, and therefore the length direction of these foundation piles 3 is the vertical direction or the substantially vertical direction. For this reason, when the front side 1A and the rear side 1B of the base frame 1 are made parallel or substantially parallel to the inclined ground surface 2A, the base frame 1 In 1, a rotational displacement is generated in which the vertical direction of the foundation pile 3 rotates about a central axis whose axial direction is the axial direction. This rotational displacement α is shown in FIG. 7 showing a state in which the foundation pile 3 is viewed from directly above. That is, in the foundation frame 1, a rotational displacement α corresponding to the inclination angle of the ground surface 2A with respect to the foundation pile 3 occurs.

  However, the base frame 1 of the present embodiment has a first rotating means constituted by the bracket member 9, the fastener 10, and the fastener 11 shown in FIGS. 5 and 7 on the head of the foundation pile 3. A first rotating means A is attached via A, and the base frame 1 is rotated with respect to the foundation pile 3 around the shaft portion 10B of the bolt 10A which is a component of the fastening device 10. The vertical direction of the shaft portion 10B of the bolt 10A is the axial direction. For this reason, the foundation frame 1 is supported by absorbing the rotational displacement α at the head of the foundation pile 3 by rotating the foundation frame 1 with respect to the foundation pile 3 with the shaft portion 10B as the central axis. After this, the above-described nut tightening operation of the fastener 10 is performed.

  In addition, another inclined ground 2 having a different ground surface 2A inclination angle can be effectively dealt with by changing the rotation amount of the base frame 1 around the shaft portion 10B of the bolt 10A.

  Further, the beam member 5 is attached to the joist member 4 via the second rotating means B constituted by the bracket member 16 and the fastener 17 shown in FIG. Is the beam member 5 with respect to the foundation pile 3 around the shaft portion of the bolt 17A which is a component of the fastener 17, more specifically, toward the inclined side of the ground surface 2A with respect to the joist member 4. It can be rotated. For this reason, the rotating operation of the beam member 5 for making the front side portion 1A and the rear side portion 1B of the base frame 1 have an inclination angle corresponding to the inclination of the inclined ground 2 can be performed by the second rotation means B. After this, the nut 17 of the fastener 17 is tightened. Thereby, the upper flange part 13 of the beam member 5 which is the solar panel arrangement surface of the base frame 1 is parallel to the inclination of the inclined ground 2 in the left-right direction in which the ground surface 2A is inclined. Accordingly, each solar panel SP fixedly placed on the flange portion 13 is also parallel to the slope of the slope 2.

  Further, another inclined ground 2 having a different ground surface 2A inclination angle can be effectively dealt with by changing the amount of rotation of the beam member 5 around the shaft portion of the bolt 17A.

  Furthermore, in order to connect the foundation frame 1 and the foundation pile 3, the cane member 20 extending obliquely upward from the foundation pile 3 is connected to the ball joint of FIG. It is connected to the foundation pile 3 as a rotation connecting portion by the means 22, and this rotation connecting portion is such that the cane member 20 rotates in the direction of the rotation displacement α of FIG. 7 with respect to the foundation pile 3. This is a connecting part that allows For this reason, even if the rotation displacement α of the foundation frame 1 with respect to the foundation pile 3 is generated by the first turning means A, the foundation frame 1 and the foundation pile 3 are connected by the cane member 20 as specified, and this cane member The base frame 1 can be supported by 20 and the foundation pile 3.

  Further, the base frame 1 must be given an elevation angle with respect to the sun. The elevation angle is determined by using the horizontal shaft portion of the bolt 11A, which is a component of the fastener 11 described in FIG. This can be ensured by rotating the base frame 1 up and down to make the amount of rotation correspond to the elevation angle and then tightening the nut of the fastener 11. Further, when the base frame 1 is pivoted up and down in this way to ensure an appropriate elevation angle of the base frame 1 with respect to the sun, the base end portion of the cane member 20 is attached to the foundation pile 3 via the ball joint means 22. After the nut 23B of the fastener 23 of the band member 24 of FIG. 6 being fixed is loosened and the height position of the band member 24 in the foundation pile 3 is adjusted, the nut 23B is tightened to perform the foundation pile 3 The height position of the base end portion of the cane member 20 can be changed to an appropriate position corresponding to the elevation angle of the base frame 1.

  In addition, each foundation pile 3 driven into the slope 2 must have the same vertical length exposed upward from the ground surface 2A of the slope 2 because there is an error in the placement depth of each foundation pile 3 In addition, when there is a difference in the vertical length, the difference in the vertical length can be eliminated by the elongated hole 8 formed in the head member 6 in FIG.

  Furthermore, the foundation piles 3 in which a plurality of pieces are arranged in the left-right direction are not accurately arranged in the front-rear direction with respect to the core L as shown in FIG. 3 and FIG. When the longitudinal displacement occurs, the displacement can be eliminated by the long hole 9C of the bracket member 9.

  Moreover, when the space | interval of the left-right direction of each foundation pile 3 does not become predetermined | prescribed magnitude | size, and the difference | error has arisen in this space | interval, this error is caused by the long hole 18 of the 1st short dimension member 5A of the beam member 5. Can be resolved.

  INDUSTRIAL APPLICABILITY The present invention can be used for solar panel mounts installed on slopes, and can also be used for mega solar systems for large-scale power generation installed on slopes.
