Since the drawings are schematically described, the dimensions of components drawn in the drawings should be determined in consideration of the following description. In the present specification, the description of “substantially” means both the state that is completely the same and substantially the same when the substantially the same is described as an example.

  The solar power generation device according to the present disclosure includes a first solar cell module having a first solar cell panel having a rectangular shape in plan view, and a second solar cell panel including a second solar cell panel including a hypotenuse that intersects at a non-right angle with respect to an adjacent side. A solar cell module. Hereinafter, the solar power generation device 10 including the standard module 11 having a rectangular shape in plan view and the half module 12 having a square shape in plan view as the first solar cell module will be described in detail. Only the half module 12 may be provided. Moreover, you may use only the standard module 11 as a 1st solar cell module like the solar power generation device 10x illustrated in FIG.

  FIG. 1 is a diagram illustrating solar power generation devices 10 and 10x that are examples of an embodiment attached to a roof 1. Although the roof 1 is a dormitory roof having the corner ridge 1c, the solar power generation device 10 may be attached to other roofs such as a square roof, a gable roof, and a single-flow roof. For example, the solar power generation device 10 is attached to a large roof surface facing the south side, and the solar power generation device 10x is attached to a small roof surface facing the east side and the west side. Below, for convenience of explanation, in the photovoltaic power generation apparatus 10 and its components, the direction along the eaves-ridge direction of the roof 1 may be referred to as the vertical direction, and the direction along the girder direction of the roof 1 may be referred to as the horizontal direction. In addition, the direction perpendicular to the base plate is defined as the vertical direction.

  As illustrated in FIG. 1, the photovoltaic power generation apparatus 10 includes a standard module 11 having a rectangular solar cell panel 11 a in plan view, a half module 12 having a square solar cell panel 12 a in plan view, and a modified module 13. (Second solar cell module). The odd-shaped module 13 has a solar cell panel 13a including a hypotenuse that intersects at a non-right angle with respect to an adjacent side. In the present embodiment, the solar cell panel 13a (deformed module 13) having a pentagonal shape in plan view is illustrated, but the second solar cell module including the hypotenuse may have a shape other than the pentagonal shape.

  As will be described in detail later (see FIGS. 3 to 6, etc.), the solar power generation device 10 includes a plurality of anchors 14 having anchor bolts 16, and a base that is fixed to the anchor bolts 16 and supports each solar cell module. Prepare. That is, each solar cell module is attached to the roof 1 using the anchor 14 and the mount. The gantry has a first support part disposed under at least one of the standard module 11 and the half module 12 and a second support part disposed under the deformed module 13. The second support part is connected to the first support part and supports the deformed module 13 using the first support part. Thereby, even if there are few anchors 14, a solar cell module can be fixed stably and the attachment structure to the roof 1 excellent in workability | operativity is realizable.

  Below, the 1st support part and the 2nd support part are comprised by another member, and the form connected mutually is illustrated, but the 1st support part and the 2nd support part may be constituted by one member. The solar power generation device may include, for example, one base gantry having a size in which base cradles 20 and 30 described later are combined.

  The solar power generation device 10 includes a row of solar cell modules along the girder direction of the roof 1. One row of solar cell modules includes, for example, three standard modules 11, one half module 12, and two variant modules 13. Two variant modules 13 are arranged at both ends of the row. In the example illustrated in FIG. 1, there is a column that does not include the half module 12. Further, the photovoltaic power generation apparatus 10x includes a row composed of only two variant modules 13. In the roof 1, the girder direction length is longer on the eave 1 a side and the girder direction length is shorter on the ridge 1 b side. Therefore, the length of the row of solar cell modules along the roof girder direction is the ridge 1 b of the roof 1. It gets shorter as it gets closer to.

  The standard module 11 is generally arranged so that the longitudinal direction is along the girder direction of the roof 1. The half module 12 has, for example, half the size of the standard module 11 and is disposed between the standard module 11 and the variant module 13. In the example illustrated in FIG. 1, another standard module 11, a half module 12, or a variant module 13 is adjacently disposed on the ridge side of the standard module 11 in two rows on the eave 1 a side. On the ridge side of the half module 12, a modified module 13 is arranged adjacently. Note that no other modules are arranged on the ridge side of the odd-shaped module 13.

  As described above, the solar cell panel 13a (the odd-shaped module 13) has a pentagonal shape in plan view. The solar cell panel 13a includes two short sides 13b, two long sides 13c that intersect each of the short sides 13b at right angles, and a hypotenuse 13d that intersects each of the short sides 13b at a non-right angle, preferably an obtuse angle. For example, the angle formed between the hypotenuse 13d and each short side 13b is about 135 °, the long sides 13c have the same length, and the short sides 13b have the same length. Each long side 13c intersects with each other at right angles, and the oblique side 13d is inclined at an angle of about 45 ° with respect to each long side 13c. The variant module 13 is arranged on the roof 1 so that the hypotenuse 13d is along the corner ridge 1c.

  In the solar power generation device 10, by arranging the deformed module 13 so that the hypotenuse 13d is along the corner ridge 1c, the space near the corner ridge 1c can be effectively used, and the number of solar cell modules that can be mounted on the roof 1 is increased. be able to. On the other hand, since the deformed module 13 is smaller in size than the half module 12, it is not easy to stably attach the deformed module 13 using the anchor 14. In the case where a conventionally known general frame is used, in order to stably support the deformed module 13, for example, it is necessary to install four anchors 14 under the deformed module 13. However, in this case, the anchor 14 may protrude from the bottom of the deformed module 13 and the appearance of the roof 1 may deteriorate.

  In the present embodiment, the deformed module base mount 30 (second base mount) is used as the second support portion, so that it is possible to stably support the deformed module 13 even if the number of anchors 14 is smaller than the conventional one. To do. Further, by using the half module base mount 20 (first base mount) as the first support portion to which the second support portion is connected, the number of anchors 14 is further increased while stably fixing the solar cell module. It can be reduced to improve workability. Details of the gantry including the base gantry will be described later.

  The odd-shaped module 13 has a module frame 100 (see FIG. 2) that is installed on the periphery of the solar cell panel 13a and is used for attachment to a gantry. The module frame 100 includes a long side frame installed at an edge portion along each long side 13c of the solar cell panel 13a, a short side frame installed at an edge portion along each short side 13b, and an oblique side 13d. And a hypotenuse frame installed at the edge. Each frame is a long member manufactured by extruding a metal material mainly composed of aluminum, for example, and surrounds the solar cell panel 13a in a state in which the respective end faces in the longitudinal direction are abutted with each other. Installed. A module frame 100 similar to the odd-shaped module 13 is also installed on the periphery of the solar cell panels 11a and 12a.

As illustrated in FIG. 2, the module frame 100 includes a frame main body 101 that has a hollow, substantially prismatic shape, a flange 102 that stands on the upper surface of the frame main body 101, and an outer groove 105 that opens toward the outside of the module. And have. Further, the module frame 100 has an inner collar 106 formed with a bottom plate 104 protruding from the inside of the module. Some module frames 100 that are not used for attachment to the roof 1 may not have the outer groove 105 and the inner flange 106.

  In the module frame 100, an inner groove 103 is formed between the upper surface of the frame main body 101 and the flange portion 102, which is a gap into which the periphery of the solar cell panel 13a can be inserted. The flange 102 extends straight from the outside of the frame main body 101 and is bent inward to have a substantially L-shaped cross section. Further, the module frame 100 has an outer groove 105 that is a gap into which a below-described fixing bracket used for fixing to the gantry can be inserted between the lower surface of the frame main body 101 and the bottom plate 104.

That is, the first frame that supports the half module 12 includes the base frame 20 and the first frame, and the second frame that supports the deformed module 13 includes the base frame 30 and the second frame.

  In the present embodiment, the gantry frame 40 is used as the first and second gantry frames. A plurality of gantry frames 40 are fixed to the base gantry 20, 30, but each length may be the same or different. In the example shown in FIG. 4, four frame frames 40 are attached to the base frame 20, and three frame frames 40 are respectively attached to the base frame 30. The gantry frame 40 attached to the oblique side portion of the base gantry 30 is longer than the other gantry frames 40. The gantry frame 40 is arranged such that its longitudinal direction is along the eaves-ridge direction.

  The base mounts 20 and 30 are fixed to the anchor bolt 16 of the anchor 14 that is fixed to the base plate 2. The anchor 14 includes a substrate 15 fixed to the base plate 2 and anchor bolts 16 erected on the substrate 15.

The base mounts 20 and 30 are fixed to the portions of the anchor bolt 16 that protrude upward from the through hole 4. A seal member 18 is provided in the gap between the through hole 4 and the anchor bolt 16 and around the through hole 4 to prevent rainwater or the like from entering under the roof tile 3. Since it is necessary to remove and process the roof tile 3 when installing the anchor 14, if the number of anchors 14 can be reduced, the workability of the solar power generation apparatus 10 is greatly improved.

  The base gantry 20 includes a bottom plate 21 to which the anchor bolt 16 is fixed, side walls 22a and 22b erected on the periphery of the bottom plate 21, and a fixing portion 23 that extends from the upper end of the side wall 22a and to which the gantry frame 40 is fixed.

  The base pedestal 20 has a rectangular shape in plan view, and has substantially the same or slightly smaller dimensions as the half module 12. Alternatively, the base mount 20 may be about half the size of the half module 12. The half module 12 is arranged on the base gantry 20 via the gantry frame 40 so as to cover the entire base gantry 20, that is, so that the base gantry 20 does not protrude from below the half module 12. A base frame similar to the base frame 20 corresponding to the shape and size of the standard module 11 is installed under the standard module 11 adjacent to the variant module 13. It is also possible to use the base mount 20 as the base mount.

  The bottom plate 21 is a plate-like portion having a rectangular shape in plan view in which a plurality of through holes 24 are formed. As shown in FIG. 5, the anchor bolt 16 is inserted into one of the plurality of through holes 24, and the tip thereof protrudes upward from the upper surface of the bottom plate 21. The bottom plate 21 is placed on the nut 17a fastened to the anchor bolt 16, and is fixed to the anchor bolt 16 by being pressed from above with the nut 17b. The outer diameters of the nuts 17 a and 17 b are preferably larger than the diameter of the through hole 24. The nut 17b is fastened to a portion protruding from the upper surface of the bottom plate 21 of the anchor bolt 16 so as to sandwich the bottom plate 21 together with the nut 17a. Generally, a washer having an outer diameter larger than the diameter of the through hole 24 is attached between the bottom plate 21 and the nuts 17a and 17b.

On the other hand, since the distance between the fixed portion 33c and the other fixed portion 33b is short, one pedestal frame 40 is fixed to each of the fixed portions 33b and 33c. In addition, the fixing | fixed part 33b and 33c are located in a line with the eaves-ridge direction.

  The base frame 30 may be provided with an L-shaped angle 36 (see FIG. 3) for reinforcing the bottom plate 31 at a position where it does not interfere with the anchor bolt 16. In the example shown in FIG. 3, two L-shaped angles 36 are fixed to the upper surface of the bottom plate 31. The L angle 36 may be provided on the base mount 20.

  The base mounts 20 and 30 are connected to each other as described above (see FIGS. 3 and 4). In this embodiment, the side wall 22b of the base gantry 20 and the side wall 32b of the base gantry 30 are arranged adjacent to each other in the spar direction, and the side walls 22b and 32b are coupled using the coupling bolt 37 and the coupling nut 38. The For this reason, the base mounts 20 and 30 function as one large base mount and can be stably supported using the three anchors 14. A plurality of connection bolts 37 are preferably attached to the side walls 22b and 32b, and a plurality of bolt insertion holes (not shown) through which the connection bolts 37 are inserted are formed.

  The base mounts 20 and 30 may be connected by, for example, welding or the like. However, in consideration of construction, transportation, storage, and the like, it is preferable that the base mounts 20 and 30 be connected to each other using bolts or the like. The base mounts 20 and 30 can be connected or separated on the roof 1. At least two connecting bolts 37 are fastened at intervals in the longitudinal direction of the side walls 22b and 32b (the eaves-ridge direction). In the example shown in FIG. 4, three connecting bolts 37 are attached side by side at equal intervals in the eaves-ridge direction.

  In the present embodiment, two anchors 14 are fixed to the bottom plate 21 of the base frame 20, and one anchor 14 is fixed to the bottom plate 31 of the base frame 30. That is, the base mounts 20 and 30 and the two solar cell modules arranged on the mount are stably supported by the three anchors 14. On the other hand, when the base mounts 20 and 30 are not connected or when the base mount 20 is not used, the base mount 30 needs to be supported by at least three anchors 14. Thus, according to the solar power generation device 10, the number of anchors 14 can be reduced, and workability is greatly improved.

  For example, one eaves side end (vertical one end) of the bottom plate 21 has one horizontal end located on the opposite side of the base gantry 30, and a ridge side end (the other vertical end of the bottom plate 21). 2), a total of two anchors 14 are fixed, one at the center in the lateral direction. The anchor 14 fixed to the eaves side of the bottom plate 21 only needs to be disposed between the horizontal center of the bottom plate 21 and one end in the horizontal direction, and the anchor 14 fixed to the ridge side of the bottom plate 21 is fixed to the bottom plate 21. What is necessary is just to arrange | position between a horizontal direction center and a horizontal direction other end.

  For example, one anchor 14 is fixed to the center frame 30 at the eave side end (vertical one end) of the bottom plate 31 at the base frame 30. The anchor 14 fixed to the bottom plate 31 may be disposed between the longitudinal center of the bottom plate 31 and one longitudinal end, and between the lateral center of the bottom plate 31 and the other lateral end. By connecting the base mounts 20 and 30, one anchor 14 fixed to the bottom plate 31 can be provided.

  7 and 8 are diagrams showing an example of the gantry frame 40 and a structure for attaching the frame to the fixing portion 33a. The mounting structure of the gantry frame 40 using the bolt fixing plate 47 illustrated in FIGS. 7 and 8 can be applied to other fixing portions including the fixing portion of the base gantry 20, and as illustrated in FIG. It can also be applied when the type of gantry frame is changed.

  As illustrated in FIGS. 7 and 8, the second frame having the base frame 30 may have a bolt fixing plate 47 to which a bolt 44 for fixing the frame 40 is fastened. By using the bolt fixing plate 47, the bolt 44 can be easily fixed and the workability is improved. The bolt fixing plate 47 can also be used for the first frame having the base frame 20. As described above, the gantry frame 40 has at least two bolt insertion holes 43, and the fixing portion 33 a has bolt insertion holes 35 through which the bolts 44 inserted into the bolt insertion holes 43 are passed. A total of four bolt insertion holes 43 are formed at both ends in the longitudinal direction of the base portion 41, one on each side in the width direction of the convex portion. The bolt insertion hole 35 is a long hole that is long in the lateral direction perpendicular to the longitudinal direction of the bolt insertion hole 43.

  At least two screw holes 48 are formed in the bolt fixing plate 47. In this embodiment, two screw holes 48 are formed in the oval or rectangular metal bolt fixing plate 47 at a predetermined interval in the longitudinal direction of the plate. The predetermined interval is the same as the interval between the two bolt insertion holes 43 formed side by side in the width direction of the base portion 41. The screw hole 48 is formed by, for example, burring a metal plate constituting the bolt fixing plate 47 and cutting a screw on the inner peripheral surface of the processed portion.

  The bolt fixing plate 47 is disposed below the fixing portion 33a so that the two screw holes 48 overlap the bolt insertion hole 35 in the vertical direction. The gantry frame 40 and the bolt fixing plate 47 are provided so that the three holes (bolt insertion holes 35 and 43, screw holes 48) overlap in the vertical direction and the fixing portion 33a is sandwiched from above and below. The size of the bolt fixing plate 47 is not particularly limited, but the width of the bolt fixing plate 47 is preferably substantially the same as or slightly smaller than the width of the fixing portion 33a. It is preferable that the bolt fixing plate 47 is disposed without a substantial gap between the bolt fixing plate 47 and the side wall 32 a of the base mount 30.

  As shown in FIG. 6, when the bolt fixing plate 47 is not used, the bolt 44 is passed from below the fixing portion 33a to the bolt insertion holes 35 and 43, and the head of the bolt 44 is fixed with a spanner. It is necessary to tighten the nut with a predetermined torque while preventing rotation. At this time, the heads of the bolts 44 must be face-to-face, and the space into which the spanner is inserted is narrow, so it cannot be said that the workability is good. Since the gantry frame 40 is fixed to the base gantry 30 by using two bolts 44 at four fixing portions, it is necessary to perform the operation eight times.

  As shown in FIGS. 7 and 8, when the bolt fixing plate 47 is used, the bolt 44 is fastened to the two screw holes 48 to some extent, so that one bolt 44 can be rotated even if the torque that can cause the joint rotation is generated. Prevent rotation. For this reason, the operation | work which inserts a spanner under the fixing | fixed part 33a and fixes a volt | bolt or a nut becomes unnecessary. Therefore, by using the bolt fixing plate 47, the bolt 44 can be easily fixed, and the workability is further improved.

  If the width of the bolt fixing plate 47 is substantially the same as or slightly smaller than the width of the fixing portion 33a, the bolt fixing plate 47 rotates when the one bolt 44 is fastened to one screw hole 48. Even if it does, rotation will be controlled because a fixed board contacts side wall 32a of base stand 30. That is, by using the bolt fixing plate 47 having a size that does not substantially leave a gap with the side wall 32a of the base gantry 30, the position of the other screw hole 48 does not move greatly, and the bolt fixing plate 47 is moved to a desired position. It becomes easy to arrange. In this case, after one bolt 44 is completely fixed, another bolt 44 can be fixed.

  9 and 10 are views showing an example of a gantry frame 50 that is another example of the embodiment and a structure for attaching the frame to the fixing portion 33a. The gantry frame 50 can be attached to other fixed parts including the fixed part of the base gantry 20. That is, the gantry frame 50 can be used as a first gantry frame and a second gantry frame.

  As illustrated in FIGS. 9 and 10, the gantry frame 50 is provided with a lower rod 53 in which a bolt insertion hole 55 for passing a bolt 44 for fixing the module to the fixing portion 33 a is formed, and the deformed module 13. And an upper collar 54. Further, the gantry frame 50 has a base portion 51 that connects the lower rod 53 and the upper rod 54 at the center in the width direction of the frame. The base portion 51 includes a pair of wall portions 51a formed perpendicular to the lower collar 53 and the upper collar 54, and a connecting portion 51b that couples the pair of wall portions 51a, and has a substantially H shape in a side view. The base 51, the lower rod 53, and the upper rod 54 are formed over the entire length of the gantry frame 50.

  In the gantry frame 50, a lower rod 53 projects from the lower end of each wall portion 51a to the outside in the width direction of the frame, and an upper rod 54 projects from the upper end of each wall portion 51a to the outside in the width direction of the frame. Further, the two upper collars 54 projecting outward from the respective wall portions 51a also project inward in the width direction of the gantry frame 50 with a predetermined gap therebetween. That is, a part of the upper collar 54 protrudes above the connecting portion 51b. The predetermined interval is set larger than the diameter of the shaft of the bolt 131 and smaller than the head of the bolt 131. The widths of the lower collar 53 and the upper collar 54 may be the same or different. In the example shown in FIG. 9, the width of the lower collar 53 is longer than the width of the upper collar 54.

  In the gantry frame 50, a bolt guide groove 52 is formed between the connecting portion 51b and the upper flange 54 so as to support the bolt 131 so as to be slidable in the longitudinal direction of the frame without being pulled out upward. The bolt 131 is a bolt for fixing the presser fitting 130 that engages with the deformed module 13 placed on the upper surface of the upper collar 54. The head of the bolt 131 is inserted into the bolt guide groove 52 so that the shaft projects upward from the upper surface of the upper collar 54 and stands along the vertical direction.

  As described above, the bolt insertion hole 55 is formed in the lower collar 53. The bolt insertion hole 55 is formed in each of the two lower collars 53 projecting outward from each wall 51a. The two bolt insertion holes 55 are arranged side by side in the width direction of the gantry frame 50. The bolt insertion hole 55 is preferably a long hole extending in the longitudinal direction of the gantry frame 50. The gantry frame 50 is arranged on the fixing portion 33a in such a manner that the bolt insertion holes 55 and the bolt insertion holes 35 of the fixing portion 33a overlap in the vertical direction, and the longitudinal directions of the holes are orthogonal to each other.

  A notch 56 is formed in the upper collar 54 at a portion overlapping the bolt insertion hole 55 in the vertical direction. Since the upper collar 54 protrudes above the lower collar 53, when the notch 56 does not exist, the upper collar 54 becomes an obstacle when the bolt 44 is passed through the bolt insertion hole 55. By forming the notch 56 at a position where it interferes with the bolt insertion hole 55, the bolt 44 can be easily attached and the workability is improved.

  The notch 56 is formed by cutting a portion of the upper collar 54 that overlaps with the bolt insertion hole 55 from the outside into a U-shape. The length of the notch 56 is, for example, the same as or slightly longer than the length of the bolt insertion hole 55, but may be shorter than the length of the bolt insertion hole 55. That is, the upper collar 54 may exist in a part above the bolt insertion hole 55 as long as there is no hindrance to the mounting of the bolt 55. In the example shown in FIG. 9, the two bolt insertion holes 55 are formed side by side in the width direction of the gantry frame 50, so that two notches 56 are formed side by side in the width direction of the gantry frame 50.

  The bolt 44 is inserted into the bolt insertion hole 55 from above the lower rod 53, for example, but may be inserted from below the lower rod 53 into the bolt insertion hole 55. The bolt 44 may be fixed using a nut, or may be fixed using the bolt fixing plate 47 described above.

  FIG. 10 shows a mounting structure at the boundary position between the half module 12 and the odd-shaped module 13. As shown in FIG. 10, when the half module 12 and the odd-shaped module 13 are fixed using the gantry frame 50 and the presser fitting 130, the module frame 120 having the outer casing 124 is used. As with the module frame 100 shown in FIG. 2, the module frame 120 can be inserted into a frame body 121 that has a hollow, substantially prismatic shape, a flange 122 that stands upright on the upper surface of the frame body 121, and the periphery of the solar cell panel. And an inner groove 123. On the other hand, the module frame 120 is provided with an outer casing 124 protruding outward.

  The half module 12 and the modified module 13 are arranged on the upper collar 54 so as to sandwich the bolt 131 erected on the gantry frame 50. The bolt 131 is fixed using a nut 132a so as not to slide along the bolt guide groove 52. The presser fitting 130 is a substantially U-shaped fitting, and has a through hole 130 a through which the bolt 131 passes. The presser fitting 130 is disposed so as to straddle the outer casing 124 of the half module 12 and the outer casing 124 of the deformed module 13, and is fixed to the bolt 131 by a nut 132 b attached to a portion of the bolt 131 positioned above the nut 132 a. The The outer bar 124 of each module is pressed against the upper surface of the upper bar 54 from above by the presser fitting 130.

  FIG. 11 and FIG. 12 are diagrams showing an example of an attachment structure of the deformed module 13 to the gantry frame 50 when the module frame 120 is used as the oblique side frame installed along the oblique side of the solar cell panel 13a.

  As illustrated in FIG. 11 and FIG. 12, the second frame that supports the deformed module 13 includes a frame 50 on which the module frame 120 that is the oblique frame is placed (an oblique frame), and stands on the frame 50. And provided bolts 131. The hypotenuse frame is not limited to the frame 50 as long as it can support the deformed module 13 and can fix the bolt 131 with the shaft facing upward.

  The second gantry further includes a plate-shaped metal fitting 140 and a holding metal fitting 130 that are arranged on the gantry frame 50 along the module frame 120. The receiving metal fitting 140 is formed with an insertion hole 141 for the bolt 131. The presser fitting 130 is fixed to the gantry frame 50 using bolts 131 and is disposed across the outer casing 124 of the module frame 120 and the receiving metal fitting 140. By using the receiving metal fitting 140, the holding metal fitting 130 can be stably attached, and the appearance of the attachment structure of the oblique side portion is improved.

  As described above, since no other solar cell module is arranged on the ridge side of the odd-shaped module 13, the presser fitting 130 cannot be arranged across the outer casing 124 of the two modules as shown in FIG. For this reason, if there is no receiving metal fitting 140, the holding metal fitting 130 is fixed in an inclined state. Specifically, since the protrusions 130 b are formed at the four corners of the presser fitting 130, the protrusion 130 b falls into the bolt guide groove 52, and the portion between the two protrusions 130 b is the edge of the bolt guide groove 52. The presser fitting 130 is fixed in a state of being in contact with. In this case, an apparently unstable impression is given compared to the case where the two protrusions 130b are in contact with the frame or the like symmetrically. By providing the receiving metal fitting 140, such a problem can be solved.

  It is preferable that the receiving metal 140 has a thickness substantially the same as the thickness of the outer collar 124 with which the presser fitting 130 abuts and a size (area) with which the two protrusions 130b of the presser fitting 130 can abut. The receiving metal 140 has a size ranging from the outer end in the width direction of one upper collar 54 to the outer end in the width direction of the other upper collar 54, for example, and covers the opening of the bolt guide groove 52. Accordingly, the presser fitting 130 can be attached in a stable state in which the two protrusions 130 b are in contact with the receiving metal fitting 140 without the protrusion 130 b falling into the bolt guide groove 52. The presser fitting 130 is fixed to the bolt 131 using nuts 132a and 132b.

  An insertion hole 141 is formed in the receiving metal fitting 140 at a portion overlapping the bolt guide groove 52. In other words, the metal fitting 140 is disposed on the gantry frame 50 so that the insertion hole 141 overlaps the bolt guide groove 52. Moreover, it is preferable that the metal fitting 140 has a hypotenuse 142 that can contact along the outer casing 124, and the hypotenuse 142 is arranged along the module frame 120. The metal fitting 140 has a quadrangular shape in plan view including a hypotenuse 142 that intersects at a non-right angle with an adjacent side. By forming the hypotenuse 142, the arrangement of the receiving metal fitting 140 is facilitated, and contributes to prevention of co-rotation described later.

  As illustrated in FIG. 12, a pin insertion hole 143 may be formed in the receiving metal fitting 140. The pin insertion hole 143 is formed in a portion overlapping the bolt guide groove 52. When the nut is fastened to the bolt 131, the rotation prevention pin is inserted into the pin insertion hole 143, so that the co-rotation of the metal fitting 140 can be prevented.

  Hereinafter, the solar power generation devices 10y and 10z, which are other examples of the embodiment, will be described in detail with reference to FIGS. In the solar power generation devices 10y and 10z, the second pedestal arranged under the deformed module 13 (second solar cell module) is connected to the first pedestal arranged under the first solar cell module, It is common with the said embodiment by the point which supports the deformed module 13 using a mount frame. On the other hand, the solar power generation devices 10y and 10z differ from the above embodiment in that they do not have a base mount. In the following, the same components as those in the above embodiment are denoted by the same reference numerals, and redundant description is omitted. Differences from the above embodiment will be mainly described.

  The solar power generation devices 10 y and 10 z include at least one of the standard module 11 and the half module 12 and a deformed module 13. Moreover, the solar power generation devices 10y and 10z include an anchor 14 having an anchor bolt 16 and a mount that is fixed to the anchor bolt 16 and supports each solar cell module. The gantry includes a first gantry arranged under the standard module 11 and / or the half module 12 and a second gantry arranged under the variant module 13. Since the solar power generation devices 10y and 10z are not provided with a base frame, the weight and cost of the frame can be reduced.

  As illustrated in FIGS. 13 and 14, in the solar power generation device 10 y, the first frame that supports the half module 12 includes a first vertical beam 60 that is disposed along the eaves-ridge direction of the roof 1. The second frame that supports the deformed module 13 is arranged along the spar of the roof 1 and extends below the half module 12 and is connected to the first vertical beam 60 (second horizontal beam); And a second vertical beam 65B disposed on the horizontal beam 70 along the eaves ridge direction. In the example shown in FIG. 13, the configuration in the case where the half module 12 is arranged beside the variant module 13 is shown. However, when the standard module 11 is arranged beside the variant module 13, the configuration illustrated in FIG. A similar configuration can be applied.

  In the solar power generation device 10y, the first vertical beam 60 and the horizontal beam 70 are fixed to the anchor bolt 16, respectively. Then, the half module 12 is placed on the first vertical rail 60, and the deformed module 13 is placed on the second vertical rail 65B. Since the second vertical beam 65B is disposed on the horizontal beam 70, it can be said that the weight of the deformed module 13 is supported by the horizontal beam 70 via the second vertical beam 65B. Further, since the horizontal beam 70 is connected to the first vertical beam 60, a part of the weight of the deformed module 13 acts on the first vertical beam 60 through the horizontal beam 70 and is supported by the first vertical beam 60. The

  The half module 12 is preferably supported by two first vertical bars 60. The first vertical bars 60 are arranged in parallel to each other on both lateral sides of the half module 12. One first vertical bar 60 is supported by at least two anchors 14. The anchors 14 are fixed one by one at, for example, both ends in the longitudinal direction of the first vertical rail 60 or in the vicinity thereof. The first vertical beam 60 may extend below the deformed module 13 disposed on the ridge side of the half module 12, and the eaves side end of the deformed module 13 may be supported by the first vertical beam 60.

  The first vertical beam 60 may be composed of a lower frame 61 and an upper frame 65A. The first vertical beam 60 has a structure in which an upper frame 65A shorter than the lower frame 61 is fixed to an upper portion of a long lower frame 61. The lower frame 61 is preferably made of a metal material mainly composed of steel in order to reduce material costs. On the other hand, the upper frame 65A is preferably made of a metal material mainly composed of aluminum from the viewpoints of formability, lightness, and the like. The upper frame 65A only needs to be installed only on the portion on which the half module 12 is placed.

  As illustrated in FIG. 15 (cross-sectional view taken along the line DD in FIG. 13), the lower frame 61 includes a bottom plate 62 fixed to the anchor bolt 16 and a pair of side walls 63 erected on the bottom plate 62. A plurality of through holes (not shown) through which the anchor bolts 16 are inserted are formed in the bottom plate 62. The lower frame 61 includes a pair of support portions 64 formed by bending the upper end portions of the side walls 63 inward. The support portion 64 increases the rigidity of the side wall 63 and functions as a hook portion on which the upper frame 65A is hooked, and strengthens the coupling force between the lower frame 61 and the upper frame 65A.

  The upper frame 65A includes a plate-like base portion 66A that is placed on the lower frame 61, a pair of leg portions 67A that are respectively fixed to the side walls 63, and a pair of flange portions 68A that are erected on the upper surface of the base portion 66A. Have. Each leg portion 67A extends downward from the lower surface of the base portion 66A and has a shape along the inner surface of the side wall 63 including the support portion 64. The upper frame 65 </ b> A is hooked on the lower frame 61 as the leg portions 67 </ b> A wrap around under the support portions 64, and the leg portions 67 </ b> A are fixed to the side walls 63 using screws 69. Each flange portion 68A extends straight upward from both ends in the width direction of the base portion 66A, and is bent inward in the middle to have a substantially L-shaped cross section.

  A fixing fitting that engages with the half module 12 is attached to the upper frame 65A. In the upper frame 65A, a guide groove is formed between the base portion 66A and the pair of flange portions 68A to support the fixing bracket so as to be slidable in the longitudinal direction of the frame (the eaves-ridge direction). The half module 12 is mounted on the pair of flange portions 68A and is fixed to the upper frame 65A using a fixing bracket supported by the guide groove. In addition, the 1st metal fitting 110, the 2nd metal fitting 111, and the 3rd metal fitting 112 can be used for a fixing metal fitting similarly to the case of the solar power generation device 10.

  As illustrated in FIG. 14, the deformed module 13 is preferably supported by two horizontal bars 70. The crosspieces 70 are arranged in parallel to each other on both sides of the deformed module 13 in the eaves-ridge direction. The length of the horizontal rail 70 arranged on the eaves side is longer than the length of the horizontal rail 70 arranged on the ridge side. Note that the two horizontal rails 70 are both arranged so as not to protrude from under the deformed module 13.

  In the example shown in FIG. 14, one end in the longitudinal direction of the horizontal beam 70 is connected to the lower frame 61 of the first vertical beam 60, and the anchor 14 is fixed to the other end in the longitudinal direction of the horizontal beam 70 or in the vicinity thereof. By connecting the horizontal beam 70 to the first vertical beam 60, one horizontal beam 70 can be supported by one anchor 14. In the case of using a conventional general vertical beam type frame, at least three, preferably four anchors 14 are installed under the deformed module 13, but the horizontal beam connected to the first vertical beam 60 is used. By using 70, the number of anchors 14 can be reduced and workability can be improved.

  The second vertical bars 65B arranged on the horizontal bars 70 are arranged in parallel to each other on both sides in the horizontal direction of the deformed module 13. One second vertical beam 65B on the half module 12 side is disposed across the two horizontal beams 70 and extends to a position exceeding both ends of the deformed module 13 in the eave building direction, and the eave side end portion and the building side of the module Support the end. For example, the fixing bracket is used to fix the deformed module 13 to the second vertical beam 65B. The other second vertical beam 65B on the opposite side to the half module 12 is shorter than the one second vertical beam 65B and is disposed on one horizontal beam 70 on the eaves side. Supports the part and the hypotenuse part.

  Similar to the upper frame 65A, the second vertical beam 65B has a plate-like base portion 66B and a pair of flange portions 68B provided upright on the upper surface of the base portion 66A. Further, a guide groove is formed between the base portion 66B and the pair of flange portions 68B to support the fixing bracket so as to be slidable in the longitudinal direction (eave ridge direction) of the second vertical beam 65B. On the other hand, there are no legs in the second vertical beam 65B.

  The second vertical beam 65 </ b> B may be directly fixed to the horizontal beam 70, but in the example shown in FIG. 14, the second vertical beam 65 </ b> B is fixed to the horizontal beam 70 via the joint fitting 77. The second vertical beam 65B and the joint fitting 77 may be welded, for example, or may be fixed to each other using bolts and nuts (not shown). The joint fitting 77 is screwed to the horizontal rail 70. The joint fitting 77 serves to fix the second vertical beam 65B to the horizontal beam 70 and to align the heights of the second vertical beam 65B and the upper frame 65A of the first vertical beam 60.

  The horizontal beam 70 includes a bottom plate 71 fixed to the anchor bolt 16, a top plate 72 on which the second vertical beam 65 </ b> B is placed via a joint fitting 77, and a side wall 73 that connects the bottom plate 71 and the top plate 72. The cross section in the width direction is substantially U-shaped. The bottom plate 71 and the top plate 72 are formed parallel to each other, and the side walls 73 are formed perpendicular to the bottom plate 71 and the top plate 72. A through hole (not shown) through which the anchor bolt 16 is inserted is formed in the bottom plate 71. The top plate 72 may be formed with a through hole through which a bolt for connecting the second vertical beam 65 </ b> B and the joint fitting 77 is passed. A plurality of insertion holes 74 for screws 77 a for fastening the joint fitting 77 are formed in the upper part of the side wall 73 side by side in the longitudinal direction of the horizontal rail 70. By forming a plurality of insertion holes 74 in the longitudinal direction of the horizontal rail 70, the degree of freedom of arrangement of the second vertical rail 65B is improved.

  The horizontal rail 70 has an engaging portion 75 that engages with the lower frame 61 of the first vertical rail 60. In the solar power generation device 10 y, the horizontal beam 70 is connected to the first vertical beam 60 by engaging an engagement portion 75 formed at one end in the longitudinal direction of the horizontal beam 70 and being fixed to the side wall 63. Is done.
