Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.
The drawings referred to in the embodiments are schematically described, and the dimensional ratios of the components drawn in the drawings may be different from the actual products. Specific dimensional ratios and the like should be determined in consideration of the following description.

  In the present specification, “substantially **” is intended to include “substantially the same” as an example and includes what is recognized as substantially the same as the same.

  Below, the structure which attaches the solar cell module 10 to the roof 100 where the tile 102 was spread using the attachment tool 30 which is an example of embodiment of this invention is illustrated. However, the application of the attachment device 30 is not limited to the roof 100. The attachment device 30 is also suitable for a roof on which another roof material (for example, slate) is spread.

  FIG. 1 shows a solar cell device attached to a roof 100 (a solar cell module 10 attached using a solar cell module mount). FIG. 2 shows a state where some of the solar cell modules 10 are removed, and FIG. 3 shows a state where the solar cell modules 10 and the gantry frame 20 are removed.

  As shown in FIGS. 1 to 3, the solar cell device attached to the roof 100 includes a solar cell module 10 and a solar cell module gantry comprising a gantry frame 20 and an attachment tool 30. The solar cell module 10 which comprises a solar cell apparatus is attached to the roof 100 using the stand for solar cell modules (the mount frame 20 and the attachment tool 30). The solar cell module 10 includes a solar cell panel 11 in which a plurality of solar cell elements are sandwiched between protective members such as glass plates, and a module frame 12 (hereinafter referred to as “frame 12”) installed on the periphery of the panel. . The frame 12 protects the periphery of the solar cell panel 11 and also functions as a member for attaching the module to the gantry frame 20. That is, the frame 12 and the solar cell module mount are an attachment structure for fixing the solar cell module 10 to the roof 100.

  In the present embodiment, the solar cell module 10 is arranged on the gantry frame 20 so that the longitudinal direction of the solar cell module 10 having a substantially rectangular shape in plan view is substantially orthogonal to the longitudinal direction of the gantry frame 20. Yes. The plurality of solar cell modules 10 are arranged so that the long sides and the short sides are substantially parallel to each other between adjacent modules. The “plan view” means a planar shape when viewed from the direction perpendicular to the light receiving surface of the solar cell panel 11.

  The frame 12 preferably has a flange 12a (see FIG. 5) along each long side. The flange portion 12a is a portion that protrudes in the width direction of the frame 12 on the side opposite to the side on which the solar cell panel 11 is disposed (hereinafter referred to as “outside”). For example, the cross-section of the flange portion 12a cut in the width direction of the frame 12 has an L shape. The flange portion 12a is formed, for example, by bending the distal end side of a portion protruding outward from the lower end of the frame 12.

  The gantry frame 20 is fixed to the attachment device 30 and disposed on the roof tile 102. More specifically, the gantry frame 20 is fixed to a shaft portion 35 described later. It is preferable that the frame 12 of the solar cell module 10 is placed on the gantry frame 20 and fixed using the flange 12a or the like. The plurality of gantry frames 20 are arranged substantially in parallel with each other at an appropriate interval. For example, the two gantry frames 20 support the two solar cell modules 10.

  The attachment tool 30 opens the through-hole 102a in the roof tile 102 that is a roof material, and fixes the solar cell module 10 to the roof plate 101 located on the back side of the roof tile 102. For example, two attachment tools 30 are provided for one gantry frame 20, and the two are preferably located in the vicinity of both ends of each gantry frame 20 in the longitudinal direction.

  In the state in which the roof tile 102 is installed, the attachment device 30 has the shaft portion 35 protruding from the back side of the roof tile 102 to the front side of the roof tile 102 through the through hole 102a. And it is suitable to attach the cap 36 and the sealing material 37 to the axial part 35 protruded from the through-hole 102a, in order to improve waterproofness. The sealing material 37 is filled in a gap between the shaft portion 35 and the through hole 102 a, and the cap 36 is attached so as to cover the sealing material 37.

  As shown in FIGS. 4 to 8, the attachment device 30 includes an anchor 31, an elastic member 32, and a support member 33. 4 is a sectional view taken along line AA in FIG. 2, FIG. 5 is a sectional view taken along line BB in FIG. 2, and FIG. 6 is an enlarged view of a portion C in FIG. FIG. 7 is an exploded perspective view showing a mounting structure of the gantry frame 20 and the mounting tool 30, and FIG. 8 is a perspective view showing the mounting tool 30.

  The anchor 31 has a fixed portion 34 and a shaft portion 35 provided on the fixed portion 34. In the mounting instrument 30, the elastic member 32, the support member 33, and the fixing portion 34 are located on the back side of the roof tile 102 with the roof tile 102 installed, and the front end side half of the shaft portion 35 protrudes to the front side of the roof tile 102. Yes. As described above, the cap 36 is attached to the attachment device 30 at a portion protruding from the through hole 102 a of the shaft portion 35. A sealing material 37 is filled in the gap between the shaft portion 35 and the through hole 102a. Then, the gantry frame 20 is fixed to the distal end side of the shaft portion 35 with respect to the cap 36.

  The fixing portion 34 is a portion that is fixed to the roof plate 101, and is formed of, for example, a metal plate in which a screw hole 34a is formed. It is preferable that the shaft portion 35 is fixed substantially perpendicular to the surface of the fixing portion 34 at the center of the fixing portion 34. The shaft portion 35 is fixed by welding or the like. A plurality of screw holes 34 a are preferably formed on the periphery of the fixed portion 34 so as to surround the shaft portion 35. The fixing | fixed part 34 is fixed on the roof board 101, for example using the drill screw 38 inserted in the screw hole 34a.

  The shaft portion 35 is a portion to which the gantry frame 20 and the like are fixed. The shaft portion 35 is arranged substantially perpendicular to the roof plate 101 by fixing the fixing portion 34 to the roof plate 101. It is preferable to form a screw groove 35 a in the shaft portion 35. In the present embodiment, a thread groove 35 a is formed over the entire length of the shaft portion 35. Thereby, it becomes easy to fix the mount frame 20 to the shaft part 35. Further, as described later, the position of the support member 33 can be adjusted using the screw groove 35a.

  For example, a screw hole 21a of the gantry frame 20 is fitted into a portion protruding from the through hole 102a of the shaft portion 35, and the gantry frame 20 is fixed using nuts 24a and 24b. Specifically, the nut 24a and the washer 25a are attached to the shaft portion 35, and the gantry frame 20 is placed on the nut 24a, and then the washer 25b, the spring washer 26b and the nut 24b are attached to the shaft portion 35, and the gantry frame 20 is attached. Fix it.

  As described above, the frame 12 of the solar cell module 10 is fixed to the gantry frame 20 fixed to the shaft portion 35. The frame 12 can be fixed using a presser fitting 22 having a substantially U-shaped cross section that presses the flange portion 12a. For example, a bolt hole is formed in the presser fitting 22, and a bolt 23 protruding from the upper surface of the gantry frame 20 is inserted into the bolt hole. In the present embodiment, a bolt 23 is inserted into the screw hole 21b from below, and a washer 25c, a spring washer 26c, a nut 24c, a presser fitting 22, a washer 25d, a spring washer 26d, and a nut 24d are sequentially attached to the shaft of the bolt 23. ing.

  The elastic member 32 has a function of improving the water tightness of the roof 100 to which the solar cell module 10 is attached. The elastic member 32 is installed on the shaft portion 35 and comes into contact with the back surface of the roof tile 102. The elastic member 32 and the back surface of the roof tile 102 are bonded by an adhesive 39 (see FIG. 15). For example, the same material as the sealing material 37 can be used for the adhesive 39. The elastic member 32 preferably closes the through hole 102a from the back side of the roof tile 102 and contacts the periphery of the through hole 102a without a gap. Thereby, the elastic member 32 can support the sealing material 37 and prevent its drop-off. Even if rainwater enters the back side from the through hole 102a due to damage to the sealing material 37 or the like, the elastic member 32 can stop the water.

  As the elastic member 32, it is preferable to use a foam having a through hole 32a through which the shaft portion 35 can be inserted. The foam is easily compressed and comes into contact with the back surface of the roof tile 102 without any gap, thereby improving water tightness. The foam applied to the elastic member 32 is not particularly limited, but is preferably a foam having an expansion ratio of 40% or more. Specific examples include foamed ethylene propylene rubber, foamed butyl rubber, foamed urethane, and the like. Moreover, the foam formed by filling resin microballoons may be used.

  The elastic member 32 has, for example, a substantially cylindrical shape in which a through hole 32a is formed at the center in the radial direction. The diameter of the through hole 32a is preferably substantially the same as or slightly smaller than the diameter of the shaft portion 35 from the viewpoint of improving water tightness. Since the elastic member 32 is an elastically deformable member, the elastic member 32 can be fitted into the shaft portion 35 even if the diameter of the through hole 32 a is slightly smaller than the diameter of the shaft portion 35.

  The support member 33 is installed closer to the base side of the shaft portion 35 than the elastic member 32. The support member 33 is a member for supporting the elastic member 32 at a predetermined position of the shaft portion 35. Specifically, the support member 33 is designed to move along the shaft portion 35 when a predetermined force or more is applied toward the base side or the tip side of the shaft portion 35. The attachment device 30 is attached to the roof plate 101 by temporarily removing the tile 102, attaching the attachment device 30 to the roof plate 101, and then installing the tile 102 in the original position again. In this case, the elastic member 32 and the support member 33 are disposed on the back side of the roof tile 102. By applying a predetermined force or more toward the base side of the shaft portion 35 to the roof tile 102, the roof tile 102 is returned to its original position. Moving. When the roof tile 102 returns to the original position, as shown in FIG. 4, the roof tile 102 comes into contact with the adjacent roof tile 102, so that a force exceeding a predetermined level cannot be applied to the roof tile 102. Accordingly, the support member 33 does not move along the shaft portion 35, and the roof tile 102 is supported at the original position. At this time, the elastic member 32 is pressed against the back surface of the roof tile 102 by the support member 33, is appropriately compressed, and comes into contact with no gap. In addition, although the structure which sticks the elastic member 32 to the back surface of the roof tile 102 with an adhesive agent without using the support member 33 is also considered, in this case, the elastic member 32 is not compressed and watertightness is inferior. Alternatively, a method of stacking a large number of elastic members 32 is conceivable, but in this case, there is a problem that not only the problem of material cost but also the height adjustment of the roof tile 102 is troublesome as will be described in detail later.

  The support member 33 supports the elastic member 32 at a suitable position of the shaft portion 35 without contacting the fixed portion 34. That is, the support member 33 is attached to the shaft portion 35 so that a gap is formed between the support member 33 and the fixed portion 34 when the roof tile 102 is installed at the original position. Thereby, the height adjustment of the roof tile 102 is facilitated, and the elastic member 32 can be appropriately compressed.

  As shown in FIGS. 9 to 11 (a perspective view, a cross-sectional view, and a bottom view of the support member 33), the support member 33 preferably has a plate-like pedestal portion 40 and a claw portion 41. The support member 33 is preferably made of metal, and is made of, for example, a highly corrosion-resistant steel plate.

  The pedestal portion 40 is a portion on which the elastic member 32 is placed, and has a through hole 40a through which the shaft portion 35 can be inserted at the center thereof. The shape and dimensions of the pedestal portion 40 can be appropriately changed according to the shape and dimensions of the elastic member 32. In the present embodiment, the pedestal portion 40 has a substantially disk shape, and the diameter thereof is substantially the same as the diameter of the elastic member 32. It is preferable that the diameter of the through hole 40 a is larger than the diameter of the shaft portion 35 and only the claw portion 41 abuts on the shaft portion 35.

  The claw portion 41 is a portion that is provided on the periphery of the through hole 40 a and is hooked on the screw groove 35 a of the shaft portion 35. The support member 33 can be fixed to the target position of the shaft portion 35 by the claw portion 41 being caught in the screw groove 35a. A plurality of claw portions 41 are preferably provided at the periphery of the through hole 40a. In this embodiment, the six claw portions 41 are provided at equal intervals along the periphery of the through hole 40a.

  The length of the claw portion 41 (the length from the base to the tip) is preferably shorter than the radius of the through hole 40a. The width of the claw portion 41 (the length in the direction orthogonal to the length direction) is preferably about 1% to 10% of the circumferential length of the through hole 40a, and more preferably about 3% to 8%.

  The claw portion 41 preferably extends in the plate thickness direction of the pedestal portion 40. Some of the claw portions 41 may extend to one side in the plate thickness direction, and the other claw portions 41 may extend to the other side of the plate thickness direction. It is particularly preferred to extend in the same direction. In the present embodiment, a first portion 41a described later is formed substantially perpendicular to the plate surface of the pedestal portion 40 (hereinafter referred to as “pedestal surface”). In addition, it is preferable that the front-end | tip of the 1st part 41a is bent to the opposite side to the axial part 35 in consideration of attachment property.

  The claw portion 41 preferably includes a first portion 41 a that extends to one side in the plate thickness direction of the pedestal portion 40 and contacts the shaft portion 35, and a second portion 41 b that is a root portion of the claw portion 41. It is. The first portion 41a preferably has a convex portion P that protrudes toward the shaft portion 35 in order to be easily caught in the screw groove 35a. The convex portion P is formed to have a size that fits into the screw groove 35a, for example. Specifically, the convex portion P is formed in a size and shape that fits at least partially between adjacent threads of the screw groove 35a. The shape of the convex portion P is not particularly limited as long as at least a part fits between adjacent threads of the screw groove 35a, and may be hemispherical as shown in FIG. Thereby, the support member 33 can be reliably stopped when the force applied to the support member 33 becomes a predetermined force or less as compared with the configuration without the convex portion P. The second portion 41b extends from the periphery of the through hole 40a to the center side of the through hole 40a, that is, to the shaft portion 35 side along the pedestal surface.

  The first portion 41 a and the second portion 41 b have an elastic function by being formed in an L shape, and play a role of increasing the degree of freedom of the installation state of the support member 33. The support member 33 is preferably in a state where the pedestal surface is inclined with respect to the axial direction of the shaft portion 35 and the direction orthogonal to the axial direction according to the shape of the back surface side of the roof tile 102, for example. By providing the portion 41a and the second portion 41b, the inclination becomes easy. That is, since the first portion 41a is easily bent in the direction along the pedestal surface, and the second portion 41b is easily bent in the plate thickness direction, it is possible to increase the inclination of the pedestal surface with respect to the horizontal direction. Become. The length of the second portion 41b extending toward the shaft portion 35 is preferably about 10% to 50%, more preferably about 15% to 40% of the radius of the through hole 40a.

12 and 13 show a state in which the support member 33 is installed on the shaft portion 35.
In the example shown in FIG. 12, the support member 33 faces the shaft portion 35, and the claw portion 41 faces the opposite side of the fixed portion 34, that is, the tip side of the shaft portion 35 (hereinafter sometimes referred to as “up”). Is installed. On the other hand, in the example shown in FIG. 13, the support member 33 faces the shaft portion 35, and the claw portion 41 faces the fixed portion 34 side, that is, the root side of the shaft portion 35 (hereinafter sometimes referred to as “down”). Is installed. The installation form of the support member 33 shown in FIG. 12 is the same as the installation form shown in FIGS.

  The installation form of the support member 33 with respect to the shaft portion 35 is preferably the form shown in FIG. 12 (hereinafter referred to as “the former”, and the form shown in FIG. 13 is referred to as “the latter”). By installing the support member 33 so that the claw portion 41 faces upward, the hook of the claw portion 41 with respect to the screw groove 35a becomes appropriate, and the movement of the shaft portion 35 of the support member 33 toward the root side is compared with the latter. Easier. In the latter case, the claw portion 41 may come into contact with the fixed portion 34 when the pressing amount of the support member 33 is large. If the contact occurs, the roof tile 102 may float. In the former case, the claw portion 41 does not come into contact with the fixing portion 34 even if the support member 33 is largely pushed down.

  With reference to FIGS. 14-17, the effect of the attachment tool 30 provided with the said structure is explained in full detail, illustrating a part of attachment process of the solar cell module 10. FIG. For the sake of clarity, the drill screw 38 is omitted in FIGS.

  As shown in FIG. 14, when the solar cell module 10 is attached to the roof 100 using the attachment tool 30, first, the fixing portion 34 of the anchor 31 is fixed to the roof plate 101. Thereby, the stable attachment of the solar cell module 10 is attained. The fixed portion 34 is fixed to the roof plate 101 using, for example, a drill screw 38, and the shaft portion 35 of the anchor 31 stands substantially perpendicular to the roof plate 101. Note that the anchor 31 is fixed to the roof plate 101 in a state where one roof tile 102 is usually removed for one attachment device 30.

  Subsequently, as shown in FIG. 15, the support member 33 and the elastic member 32 are sequentially fitted into the shaft portion 35 and installed. At this time, the adhesive 39 is applied to the upper surface of the elastic member 32 along the outer peripheral edge. Next, the roof tile 102 (hereinafter referred to as “specific roof tile 102”) once removed to fix the anchor 31 is attached to the original position again. The specific roof tile 102 is formed with a through hole 102a through which the shaft portion 35 is passed. The dimension of the through hole 102 a can be changed as appropriate according to the dimension of the shaft portion 35. For example, when the diameter of the shaft portion 35 is 16 mm, the diameter of the through hole 102a is 20 mm to 35 mm. In this case, it is preferable to use an elastic member 32 having a diameter of about 50 mm to 80 mm.

  As shown in FIG. 16, when the specific roof tile 102 is installed in the original position through the shaft portion 35 in the through hole 102 a, the elastic member 32 and the support member 33 are pushed down by the specific roof tile 102. That is, the elastic member 32 and the support member 33 need to be installed at a position where they can be pushed down by the specific roof tile 102. The support member 33 can be pushed down using the roof tile 102 because the claw portion 41 is installed on the shaft portion 35 by being caught in the screw groove 35a. Further, by setting the support member 33 with the claw portion 41 facing upward, the degree of hooking of the claw portion 41 becomes appropriate, and it is easy to adjust the position of the support member 33 by pushing down the specific roof tile 102. Become.

  When the specific roof tile 102 is pushed down, the elastic member 32 is compressed, and the support member 33 is pushed down through a restoring force that the elastic member 32 tries to return to its original shape. In the example shown in FIG. 16, a part of the elastic member 32 is greatly compressed by the curved surface shape of the back surface of the specific roof tile 102. Thereby, one side of the base part 40 is pushed down, the base surface is inclined with respect to the horizontal direction, and the other side of the base part 40 is lifted upward. In the present embodiment, by providing the second portion 41 b in the claw portion 41, the inclination of the pedestal surface corresponding to the back surface shape of the specific roof tile 102 is facilitated.

  When the specific roof tile 102 is pushed down to its original position, as shown in FIG. 17, the elastic member 32 closes the through hole 102a and contacts the peripheral portion of the through hole 102a without a gap. The elastic member 32 can be brought into contact with the curved surface shape of the back surface of the specific roof tile 102 when the support member 33 is tilted, and is pressed against the back surface in an appropriately compressed state as a whole. When the position of the specific roof tile 102 is to be adjusted again, it can be readjusted by applying a predetermined force or more to the support member 33 toward the distal end side or the root side of the shaft portion 35.

  When the specific roof tile 102 is installed at the original position, the sealing material 37 is then filled in the gap between the through hole 102 a and the shaft portion 35, and the cap 36 is fitted into the shaft portion 35. Then, the gantry frame 20 is fixed to the distal end side of the shaft portion 35, and finally the frame 12 of the solar cell module 10 is fixed on the gantry frame 20. The sealing material 37 may be applied to the upper surface of the elastic member 32 in advance before attaching the specific roof tile 102. Thereby, the adhesiveness of the elastic member 32 to the back surface of the specific roof tile 102 can be further improved.

  As described above, according to the attachment tool 30, the solar cell module 10 can be stably attached to the roof 100, and rainwater can be prevented from entering the back surface of the specific roof tile 102. Due to the function of the support member 33, the elastic member 32 is supported at a suitable position of the shaft portion 35 and at a suitable angle corresponding to the shape of the back surface of the specific roof tile 102, whereby the through-hole 102 a is formed. Water tightness can be increased. In addition, the support member 33 can be easily adjusted in position by pushing down the specific roof tile 102, thereby realizing good workability.

The above embodiment can be appropriately changed in design without departing from the object of the present invention.
For example, as illustrated in FIG. 18, the support member 33 x may include a protrusion 42 that protrudes from the outer edge of the pedestal portion 40 toward the elastic member 32. It is preferable that a plurality of the protruding portions 42 are provided along the outer edge of the pedestal portion 40 and protrude in the same direction as the direction in which the claw portions 41 extend. In the example shown in FIG. 18, the eight protrusions 42 are provided at equal intervals, but the number and arrangement thereof are not limited to this.

  The protrusion 42 plays a role of suppressing excessive compression of the elastic member 32. That is, the support member is pushed down through a restoring force that compresses the elastic member 32 to return to the original shape. For example, when the catch of the claw portion 41 is strong, the support member is not lowered and the elastic member 32 is not lowered. May be overcompressed. In the support member 33x, in such a case, a strong push-down force acts when the protrusion 42 contacts the back surface of the specific roof tile 102. Thereby, the support member 33x is pushed down, and the appropriate compression state of the elastic member 32 is maintained.

  As illustrated in FIG. 19, the support member 33 y without the claw portion 41 may be used. As the support member 33y, for example, a hard rubber ring can be used. In the example shown in FIG. 19, the screw groove 35a is formed only on the tip side of the shaft portion 35y. For example, the diameter of the portion where the screw groove 35a is not formed is designed to be substantially the same as the diameter of the through hole of the support member 33y. ing. Also in this case, by placing the elastic member 32 on the support member 33y and pressing down the roof tile 102 from above, the elastic member 32 is compressed and comes into contact with the back surface of the roof tile 102, thereby ensuring watertightness.
