Thereafter, the washer 47, the spring washer 48 and the upper fixing nut 46 are sequentially fitted into the first anchor bolt 44, and the upper fixing nut 46 is tightened. Thereby, the first mounted portion 42 is fixed to the first fixed portion 41.

  As shown in FIG. 13, in this step, the mounting direction of the first mounting portion 42 is set so that the extending direction of the first elongated hole 55 is orthogonal to the arranging direction of the first support 31 (the second direction D2). adjust. Further, among the plurality of first supports 31, the height (the distance from the top surface 2 of the flat roof) of the first inclined surface 54 is adjusted to be the same. Thereby, when mounting a module locking tool on the 1st slope 54 in a below-mentioned step, a module locking tool can be kept horizontal. For example, when there is a slight inclination on the top surface 2 of the flat roof, such level adjustment is necessary.

  Next, the second support 32 is fixed on the top surface 2 of the flat roof (second fixing step). In this step, first, the second fixed portions 91 equal in number to the first fixed portions 41 are prepared, and these are arranged at positions separated from the first fixed portion 41 in the first direction D1. Specifically, as shown in FIG. 13, a plurality of second fixed portions are arranged such that one second fixed portion 91 and one first fixed portion 41 are linearly arranged in the first direction D1. 91 are linearly arranged at intervals in the second direction D2. Then, as in the case of the first fixed portion 41, the second fixed portion 91 is fixed on the top surface 2 of the flat roof by driving the screw 4 so as to reach the ALC panel 5.

  Subsequently, the second mounted portion 92 is attached to the second fixed portion 91. This mounting procedure is substantially the same as when the first mounted portion 42 is mounted to the first fixed portion 41. Referring to FIG. 10, first, upper fixing nut 96, washer 97 and spring washer 98 are removed from second anchor bolt 94. Then, the second anchor bolt 94 is inserted into the second bolt hole 101A of the second bolt fixing portion 101, and the lower surface of the second bolt fixing portion 101 is brought into contact with the upper surface of the lower fixing nut 96. Thereafter, the washer 97, the spring washer 98 and the upper fixing nut 96 are sequentially fitted into the second anchor bolt 94, and finally the upper fixing nut 96 is tightened. Thereby, the second attached portion 92 is fixed to the second fixed portion 91. According to such a procedure, the second support 32 is fixed on the top surface 2 of the flat roof at a position away from the first support 31 in the first direction D1.

  As shown in FIG. 13, in this step, the mounting direction of the second attached portion 92 is adjusted such that the direction in which the second elongated hole 105 extends is the same as the direction in which the first elongated hole 55 extends. Further, as described above, in order to maintain the horizontal state of the module fastener, adjustment is made so that the heights of the second inclined surfaces 102 (the distance from the top surface 2 of the flat roof) become the same among the plurality of second supports 32. Do. Further, the position at which the second support 32 is fixed is determined such that the first inclined surface 54 and the second inclined surface 102 are located on the same plane.

  In addition, although this embodiment demonstrated the case where the 2nd support 32 was fixed, after fixing the 1st support 31, it is not limited to this order. That is, the first support 31 may be fixed after the second support 32 is fixed, or the first support 31 and the second support 32 may be fixed alternately.

  Next, the pair of module fasteners (first and second module fasteners 21 and 22) are fixed to each of the first mounting portion 42 and the second mounting portion 92 (third fixing step). As shown in FIG. 14, first, the first module stopper 21 is prepared, and is disposed so as to straddle the plurality of first supports 31. Specifically, referring to FIG. 9, the first placement portion 62 is placed on the first inclined surface 54 so that the insertion holes 62A formed in the first placement portion 62 overlap the first elongated holes 55. Place it. Then, the first fastening member 61 is inserted into the insertion hole 62A and the first long hole 55, and the first nut 61A is attached to the tip of the first fastening member 61. Then, the first module locking member 21 is fixed to the first mounting portion 42 (first inclined surface 54) by tightening the first nut 61A.

  The second module stopper 22 is also fixed to the second mounting portion 92 in the same manner as the first module stopper 21. As shown in FIG. 14, first, the second module stopper 22 is disposed so as to straddle the plurality of second supports 32. Subsequently, as shown in FIG. 10, the second fastening member 66 is inserted into the insertion hole formed in the bottom of the second placement portion 64 and the second elongated hole 105, and the second fastening member 66 is Attach the nut 62A. Then, by tightening the second nut 62A, the second module stopper 22 is fixed to the second mounting portion 92 (second inclined surface 102). In addition, the order which fixes the 1st module locking tool 21 and the 2nd module locking tool 22 may be reverse to the said order.

  In this step, while the second nut 62A is fully tightened, the first nut 61A is temporarily tightened. Therefore, in this state, by sliding the first fastening member 61 along the first elongated hole 55, the position of the first module stopper 21 with respect to the first mounted portion 42 can be adjusted.

  If the holes into which the first and second fastening members 61 and 66 are inserted are not long holes in the first and second attachment portions 42 and 92, the following problems may occur. That is, when fixing the first and second supports 31 and 32 as shown in FIG. 13, a construction error occurs, whereby the position of the first and second supports 31 and 32 in the first direction D1 It may shift. In this case, if the insertion holes of the first and second fastening members 61 and 66 are not long holes, such errors can not be absorbed. It can not be arranged linearly along the direction D2, and as a result, the mounting unit 1 is inclined. When three or more of the first and second supports 31, 32 are arranged, it is difficult to arrange the first and second module fasteners 21, 22 across three or more supports. Become. On the other hand, by making the insertion holes of the first and second fastening members 61 and 66 into long holes as in the present embodiment, it is possible to solve the problem due to an error in the construction of the anchor as described above.

  Next, the solar cell module 10 is fixed so as to be sandwiched from both sides by a pair of module locking tools (locking step). In this step, as shown in FIGS. 15 and 16, first, the second locking portion 65 is locked to the second edge 12 in a state where the first edge 11 side of the solar cell module 10 is lifted. Specifically, the second claw portion 65A provided at the tip of the second locking portion 65 is hooked on the second projecting portion 12A provided at the second edge portion 12.

  Subsequently, as shown in FIG. 15 and FIG. 17, the first edge 11 side of the solar cell module 10 is lowered, and the first claw portion 63A is hooked to the first projecting portion 11A, whereby the first edge 11 is formed. The first locking portion 63 is locked. As described above, since the first nut 61A is in a temporarily tightened state, the position of the first module locking member 21 is adjusted so that the first claw portion 63A is reliably hooked on the first projecting portion 11A. It is also good.

  Thereafter, by fully fastening the first nut 61A, the position of the first module stopper 21 with respect to the first mounted portion 42 is completely fixed. In this manner, the first and second module fasteners 21 and 22 are respectively locked to the first and second edges 11 and 12 of the solar cell module 10, and the solar cell module 10 The two module fasteners 21 and 22 are fixed in a state of being sandwiched from both sides.

  Next, the biasing mechanism 80 of the first support 31 biases the first fastening member 61 toward the solar cell module 10 in the direction in which the first elongated hole 55 extends (biasing step). In this step, as shown in FIG. 18, the screw 81 is inserted into the screw hole 82. Then, the side surface of the first module locking device 21 (the first placement portion 62) (a surface rising vertically from the first inclined surface 54) is pressed toward the solar cell module 10 by the tip of the screw 81. That is, the first fastening member 61 is attached to the solar cell module 10 by pushing the side surface of the first placement portion 62 from the upper side to the lower side along the first inclined surface 54 by the tip of the screw 81. Power up. Accordingly, movement of the first fastening member 61 in the direction away from the solar cell module 10 along the first elongated hole 55 can be restricted. Therefore, movement of the first module locking member 21 in the direction away from the solar cell module 10 together with the first fastening member 61 is also restricted, so that the first locking portion 63 is disengaged from the first edge 11 and thus the sun It is possible to prevent the battery module 10 from falling off.
