Description

  The present invention relates to a mechanism for holding a corner member arranged at a corner of a solar cell module array.

  2. Description of the Related Art Conventionally, when a plurality of rectangular solar cell modules are used to form a solar cell module array on a roof surface, a plurality of solar cell module rows arranged in a girder direction are arranged from the eaves side to the ridge side.

  In the roof of a general house, the length of the side end of the roof surface in the girder direction often changes from the eaves side to the ridge side. For example, if the length in the girder direction decreases from the eaves side to the ridge side, the number of solar cell modules constituting the solar cell module row increases from the eaves side to the ridge side according to the roof shape. Less. For this reason, both ends of the solar cell module array (ends in the girder direction of the roof) have a stepped shape, resulting in poor design.

  In view of the above problem, by disposing a substantially triangular corner cover or a solar cell module (hereinafter, referred to as a “corner member”) at both ends of the solar cell module row, the both ends of the solar cell module array are straightened. Is known (for example, see Patent Document 1).

  The configuration of Patent Document 1 is as follows.

  Mounts extending from the eaves side to the ridge side are arranged at equal intervals in the girder direction, and the lengths of the mounts increase from both ends in the girder direction toward the center. Then, a rectangular solar cell module is disposed between the adjacent mounts from the eave side to the ridge side, and is fixed to the mount. Since the positions of the ends of the gantry do not match on the ridge side, a rectangular solar cell module cannot be arranged. Therefore, a substantially right-angled triangular corner member is disposed at the ridge side end of the solar cell module row arranged from the eaves side to the ridge side. In the corner member having a substantially right triangle, one of the sides forming a right angle is fixed to a gantry, and the other is fixed to an adjacent rectangular solar cell module. With the above-described configuration, substantially right-angled triangular corner members are continuously located at both end portions of the solar cell module array, and both end portions of the solar cell module array are linear.

Japanese Patent No. 3692292

  However, the above Patent Document 1 is based on the premise that substantially right triangular corner members of the same size are used. Therefore, the inclination angles of both end portions of the solar cell module array are determined, and the shape of the solar cell module array cannot be flexibly adjusted to the roof shape. In addition, even if an attempt is made to use corner members of different sizes and shapes in order to match the roof shape, in the configuration of Patent Document 1 described above, mounts of various lengths are prepared, or the corner members are fixed to the mount unless the mount is extended. Not practical.

  The present invention has been made in view of the above problems, and provides a highly practical corner member holding mechanism capable of holding corner members of various sizes and shapes and contributing to the formation of a highly designed solar cell module array adapted to a roof shape. The purpose is to do.

The present invention is arranged at a corner of a solar cell module row fixed to a gantry installed at a fixed interval on an installation surface, a side extending in the same direction as the gantry extends, and A holding mechanism for a corner member having opposing sides,

FIG. 1B is a view for explaining the configuration and arrangement of the corner member 3, and the first and second stage members from the top in FIG. 1A are omitted. In this specification, the girder direction indicates the direction of the arrow X1-X2, and the water flow direction indicates the direction of the arrow Y1-Y2. The eaves side indicates the arrow Y2 side, and the ridge side indicates the arrow Y1 side.

  The roof shape of the roof surface 100 which is the installation surface of the solar cell module array shown in FIG. 1A was a parallelogram. This is to explain that the corner member holding mechanism of the present embodiment can exhibit a design property not only on a normal roof shape but also on a roof surface of various shapes. Therefore, the corner member holding mechanism of the present embodiment can be similarly implemented in a roof shape other than a parallelogram, such as a typical ridged roof or gable roof. Further, the installation surface may be on a wall surface or the ground of a building.

  On the roof surface 100 of the present embodiment, a plurality of pedestals 2 parallel to the girder direction are installed at regular intervals in the water flow direction, and a plurality of rectangular solar cell modules 1 are fixed to the pedestal 2. Further, a corner member 3 is held at a corner of the solar cell module 1 to form a solar cell module array AR.

  The corner member 3 in the illustrated example has a flat panel 300 and a frame body 30, and the outer peripheral edge of the panel 300 is surrounded by the frame body 30. The frame body 30 has a first side 31, a second side 32, and a hypotenuse 33, which form a substantially right angle. The acute angle on the ridge side (the arrow Y1 side) of the substantially right triangle is horizontal (along the gantry 2). (Direction). The first side 31 faces the solar cell module 1, and the second side 32 and the third side 34 extend in the same direction as the direction in which the gantry 2 extends. By arranging the corner members 3 at the corners of the solar cell module 1, both side edges of the solar cell module array AR are linear, and can exhibit design properties.

  Conventionally, as a corner member disposed at a corner of the solar cell module 1, a substantially right-angled triangular corner member of the same size has been used. However, in the present embodiment, as shown in FIG. 1A, corner members 3 having various shapes are used.

  In the solar cell module array AR of FIG. 1, a corner member 8 of the same size is installed in order from the left side (arrow X1 side) to the right side (arrow X2 side) → the solar cell module 1 → the corner member 3 that is not the same size. An example is shown. However, as the plurality of corner members 8 arranged on the left end (on the arrow X1 side) of the solar cell module array AR, corner members 3 that are not the same size may be arranged as necessary. On the other hand, in the plurality of corner members 3 arranged on the right end (arrow X2 side) of the solar cell module array AR, the third side 34 is formed to be longer as going from the eaves side to the ridge side (arrow Y2-Y1 direction). Corner members 3 of various shapes are arranged. The corner member 3 is not limited to the shape shown in the illustrated example, but may be a polygonal shape having a triangle or more.

  In the present embodiment, by using the corner member holding mechanism, it is possible to use the corner members 3 formed in a plurality of shapes so as to exhibit a design property on the roof surface having various shapes.

  Hereinafter, a corner member holding mechanism according to the present embodiment that enables use of the corner members 3 having various shapes will be described with reference to FIGS. 2 to 5. 2 to 5 are partially enlarged views at a point F in FIG. 1B.

  FIG. 2 is a partially enlarged perspective view showing a state where the corner member 3 is held on the gantry 2 by the holding mechanism. FIG. 2 omits the panel 300n of the eave-side corner member 3n and the solar cell module 1 for the sake of explanation. FIG. 3A is an exploded perspective view illustrating the relationship among the gantry 2, the corner member 3, and the first holding member 4. FIG. FIG. 3B is an assembling diagram illustrating an assembling state of the gantry 2, the corner member 3, and the first holding member 4, and is a perspective view of the solar cell module array AR as viewed from the left side (the arrow X2 side). FIG. 3C is a side view of FIG. 3B. The frame body 30 of the corner member 3 shown in FIGS. 3A to 3C shows only the first side 31 for the sake of explanation.

  FIG. 4 is a partial perspective view illustrating the relationship among the gantry 2, the corner member 3, and the second holding member 5.

And a second holding member 5.

(First holding member 4)
First, the arrangement of the first holding member 4 at the location F will be described with reference to FIGS. The first holding member 4 is connected to an end of the gantry 2.

  The gantry 2 to which the first holding member 4 is connected has a base part 21 and a standing part 22 erected from the base part 21 and having a T-shaped cross section when viewed from above. The base 21 has a pedestal 21a having a threaded screw hole 21b, and a flange 21c extending horizontally from the top of the screw hole 21b. A gap S1 is formed between the bottom surface of the pedestal 21a and the lower surface of the flange portion 21c. Opposite sides of the adjacent solar cell module on the eaves side and the solar cell module on the ridge side are held by the upright portion 22 and the base portion 21 of the same gantry 2.

  The first side 31 constituting the frame body 30 has a side portion 313 and a first flange portion (hereinafter, referred to as an “upper flange portion”) protruding from one end (upper side (arrow Z1 side)) of the side portion 313. 311, and a second flange portion (hereinafter, referred to as “lower flange portion”) 312 protruding from the other end (lower side (arrow Z2 side)) of the side portion 313.

  Further, the frame body 30 is provided with a third flange portion (hereinafter, referred to as “middle flange portion”) 314 having an L-shaped cross section and protruding from substantially the center of the side portion 313. Each flange projects from the side 313 in the same direction. The middle flange portion 314 has a connection side 314a, one side of which is connected to a substantially central position of the side portion 313, and a rising side 314b, which rises in the orthogonal direction from the other side of the connection side 314a.

  The tip of the rising side 314b is located closer to the lower flange 312 than the upper flange 311. A gap S2 is provided between the rising side 314b and the upper flange 311. At the end of the middle flange 314, a cutout portion 314c is formed by cutting out a part of the upright side 314b.

  The assembling of each side constituting the frame body 30 is performed by, for example, an assembling configuration of the first side 31, the third side 34, and the oblique side 33 shown in FIG. In other words, the middle flange portion 344 of the third side 34 is laid between the middle flange portion 314 provided on the first side 31 and the middle flange portion 334 provided on the hypotenuse 33. At this time, the middle flange portion 344 is arranged at the positions of the cutout portion 314c of the middle flange portion 314 and the cutout portion 334c of the middle flange portion 334. Therefore, the middle flange portion 344 of the third side 34 is held on the connection sides 314a, 334a of the middle flange portions 314, 334.

  Although not particularly shown, the frame body 30 is configured by assembling the first side 31 and the second side 32 and the second side 32 and the oblique side 33 based on the same technical idea.

  When each side of the frame body 30 is assembled in the above-described configuration, a common gap S2 is formed on the same plane between the upper flange portion of each side and the rising side of the middle flange portion. 2). The panel 300 of the corner member 3 is inserted into the gap S2, and the panel 300 is held by the lower surface of the upper flange portion 311 and the upper surface of the upright side 314b. Note that the panel 300 may be any plate-shaped one, and may be a solar cell module.

  The first side 31 constituting the frame body 30 of the present embodiment includes a notch 312a in which the lower flange 312 is cut out at the other corner member side (ridge side (arrow Y1 side)). An extension 313a is formed. In addition, the extending part 313a corresponds to the side part 313 where the notch part 312a is located.

  The first holding member 4 constituting the holding mechanism of the corner member 3 includes a connecting portion 41 that can be connected to an end of the gantry 2 on one side (the arrow X2 side) in the direction in which the gantry 2 extends, and the corner member 3. Is a movement restricting portion that restricts movement in the direction in which the gantry 2 extends (the girder direction (arrow X1-X2 direction)) and movement in the direction orthogonal to the girder direction (water flow direction (arrow Y1-Y2 direction)). Unit 42.

  The connecting portion 41 extends in the width direction of the gantry 2 (the direction orthogonal to the beam direction (the direction of the arrow Y1-Y2)). The connecting portion 41 has a bolt hole 41a formed at a position corresponding to the screw hole portion 21b of the pedestal 21a of the pedestal 2, and a support piece 41b for holding the flange portion 21c. The support piece 41b protrudes toward the gantry 2 side.

  The protruding portion 42 is connected to a surface (arrow X2 side) opposite to the gantry 2 at an eaves-side end (arrow Y2 side) of the connecting portion 41. The protruding portion 42 extends in a direction opposite to the gantry 2 (on the arrow X2 side), and has a bent end portion. Therefore, the projection 42 has an inverted L-shaped cross section, and has a side surface 42a facing the gantry 2 side and a side surface 42b facing the eaves side.

  In the first holding member 4 having the above configuration, the support piece 41b is disposed in the gap S1 between the bottom surface of the pedestal 21a of the pedestal 2 and the lower surface of the flange portion 21c, and the bolt hole 41a is connected to the screw hole portion 21b of the pedestal 21a. It is arranged at the end of the gantry 2 in a matched manner. Then, the first holding member 4 is attached to the end of the gantry 2 by screwing the bolt B1 from the bolt hole 41a of the connecting portion 41 toward the screw hole 21b of the pedestal 21a.

  Then, the first side 31 constituting the frame body 30 of the corner member 3 is arranged along the first holding member 4 connected to the gantry 2. At this time, the first holding member 4 is located in the notch 312a. That is, the extending portion 313a of the first side 31 is opposed to the side surface 42a of the projection 42 constituting the first holding member 4 on the side of the gantry 2, and the end of the lower flange portion 312 of the first side 31 is projected. It faces the eave-side side surface 42 b of the part 42.

  Therefore, the protrusion 42 can restrict the movement of the corner member 3 in the beam direction by the contact between the side surface 42a and the extending portion 313a. In addition, the protrusion 42 can restrict the movement of the corner member 3 in the water flow direction when the side surface 42b on the eaves side contacts the end of the lower flange portion 312 of the first side 31.

  The illustrated protrusion 42 has a case where the tip is formed in a bent shape, but the shape is not limited to this, and the protrusion 42 may have a curved shape such as a U-shape or a semi-circular shape. It is preferable to increase the contact area with one side 31 to increase the regulating force. Further, in the present embodiment, the protrusion 42 having the above-described configuration is described as an example of the movement restricting unit. May be implemented.

(Second holding member 5)
Next, the second holding member 5 will be described with reference to FIGS.
As shown in FIG. 1 (B), a part of the third side 34n of the corner member 3n on the eave side and a part of the second side 32m of the corner member 3m on the ridge side on the arrow X2 side are outside the gantry 2 (arrows). X2 side). The second holding member 5 of the present embodiment is installed at a position protruding outward.

  The illustrated second holding member 5 includes a main holding member 51 and an auxiliary holding member 52. The main holding member 51 and the auxiliary holding member 52 are bolted to the outside of the third side 34n of the corner member 3n on the eave side. The main holding member 51 and the auxiliary holding member 52 are arranged in parallel in the direction of the third side 34n. The distance between the main holding member 51 and the auxiliary holding member 52 arranged in parallel is appropriately changed according to the length of the third side 34 of the frame body 30 and the like. In the corner member 3 used in FIG. 1A, the third side 34 becomes longer toward the ridge side (arrow Y1 side). Therefore, the distance between the main holding member 51 and the auxiliary holding member 52 may be increased toward the ridge. When the length of the third side 34 is very short and both the main holding member 51 and the auxiliary holding member 52 cannot be installed, only the main holding member 51 is provided. That is, the second holding member 5 of the present invention may be only the main holding member 51.

  The main holding member 51 has a bolt hole (not shown) and is fixed to the third side 34n of the corner member 3n on the eave side, and a side 513 and one end of the side 513 (from above (arrow Z1 side)). A first flange portion (hereinafter, referred to as an “upper flange portion”) 511 which is a protruding portion protruding toward the ridge-side corner member 3 m, and the other end of the side portion 513 (the lower side (arrow Z2 side)). It has a second flange portion (also referred to as a “lower flange portion”) 512 which is a protruding portion protruding toward the corner member 3m on the ridge side.

  The auxiliary holding member 52 has an upper flange portion 521, a lower flange portion 522, and a side portion 523 similarly to the main holding member 51. A bolt hole (not shown) is formed in the side portion 523.

  The outer surfaces of the side portions 513 and 523 are in contact with the outside of the third side 34n of the corner member 3n on the eave side, and the main holding member 51 and the auxiliary holding member 52 are joined by bolts B2 and B3. The upper flange portion 521, the lower flange portion 522, and the side portion 523 hold the second side 32m of the ridge-side corner member 3m.

  The upper flange portion 511 of the main holding member 51 of the present embodiment is provided with an elongated hole 511a extending in a direction along the second side 32m. A stop 514 for stopping the movement of the corner member 3m in the girder direction is provided in a space formed by the upper flange portion 521, the lower flange portion 522, and the side portion 523 of the main holding member 51. The stopper 514 has, for example, an L-shape, and has an upper side 514a in contact with the upper flange 511 and a vertical side 514b extending vertically from one end of the upper side 514a into the space. The stop 514 in the illustrated example has an L-shape, but is not limited to this, and may have a C-shape or a U-shape. A screw hole is provided in the upper side 514a. The vertical side 514b is arranged so as to come to the gantry 2 side (arrow X1 side) in the space of the main holding member 51, and regulates the movement of the corner member 3m accommodated in the space in the girder direction. Specifically, as shown in FIG. 5, the vertical side 514b is disposed at a position near the second side 32m of the corner member 3m, so that the vertical side 514b contacts the end of the second side 32m. Thus, the movement of the corner member 3m in the girder direction is restricted.

  The stopper 514 is positioned and fixed in the space of the main holding member 51 by being fastened to the screw hole of the upper side 514a by a bolt B4 which is a fixing member inserted into the long hole 511a of the upper flange 511. . The stopper 514 having the above-described configuration is slidable by the elongated hole 511a within the opening range of the elongated hole 511a. Therefore, it is possible to finely adjust the fastening position of the stopping portion 514 appropriately in accordance with the site.

  Although the stopper 514 in the illustrated example is connected to the upper flange 511 side, it is not limited thereto, and may be connected to the lower flange 512 side.

  The portions of the corner member 3n on the eave side and the corner member 3m on the ridge side projecting from the gantry 2 are supported by the second holding member 5 with each other. Therefore, the corner member 3n on the eaves side and the corner member 3m on the ridge side are prevented from hanging down or falling toward the installation surface such as the roof at the portion protruding from the gantry 2. Further, the second holding member 5 may be constituted by a main holding member 51 and an auxiliary holding member 52, and by changing a fixing interval between the main holding member 51 and the auxiliary holding member 52, the eave-side corner member 3n Even if the length of the part protruding from the gantry 2 of the corner member 3m on the ridge side becomes long, it is possible to efficiently support each other.

  The above-described holding mechanism and holding structure of the corner member are similarly implemented at other corner portions. Therefore, when the corner member holding mechanism of the present embodiment is implemented, even if the corner member has various sizes and shapes, the solar cell module can be effectively held and has a high designability with respect to various roof shapes. An array can be formed.

  Next, a mechanism for holding a corner member at a location G of the solar cell module array AR shown in FIG. 1A will be described with reference to FIGS. FIG. 6 omits the solar cell module 1 for the sake of explanation.

    FIG. 6A is a partially enlarged perspective view of a portion G shown in FIG. 1A, and is a partial perspective view illustrating the relationship among the gantry 2, the corner member 3, and the holding mechanism. FIG. 6A is a perspective view of the solar cell module array AR as viewed from the ridge side (the arrow Y1 side). FIG. 6B is a partial side view of FIG. 6A and is a partially transparent view.

  A point G shown in FIG. 1A shows a connection point between the solar cell module 1up and the corner member 3up arranged on the most ridge side (hereinafter, referred to as the "topmost side") of the solar cell module array AR. .

  The holding mechanism of the uppermost corner member 3up continuously contacts the first holding member 400 connected to the end of the gantry 2 and a part of the gantry 2 and the third side 34up of the corner member 3up. The reinforcing member 6 is included.

  The reinforcing member 6 has a substantially U-shaped cross section, and has a length extending from a part of the gantry 2 to at least a part of the third side 34up of the corner member 3up. At the position of the gantry 2, the reinforcing member 6 is held by the upright portion 22 and the base portion 21. Further, the cross-sectional shape of the reinforcing member 6 may be a substantially C shape, a substantially I shape, or the like.

  The first holding member 400 of the illustrated example is different from the first holding member in that a restricting portion 430 for restricting the movement of the reinforcing member 6 in the ridge direction is provided on the ridge side surface (arrow Y1 side) of the connecting portion 410. It is different from the member 4.

  The restricting portion 430 has a base portion 430a connected to the ridge side surface opposite to the protrusion 420 of the connecting portion 410, and an L-shaped arm portion 430b connected to the upper end of the base portion 430a. ing. The arm 430b prevents the reinforcement member 6 from moving in the ridge direction.

  In the illustrated example, a holding member 7 for holding the reinforcing member 6 is bolted to the outside of the third side 34up of the corner member 3up. The holding member 7 has a substantially U-shaped cross section, and the reinforcing member 6 is inserted into a space formed by the U shape. The holding member 7 in the illustrated example may have substantially the same configuration as the auxiliary holding member 52 shown in FIG.

  At the end opposite to the end supported by the gantry 2, a gap is formed between the reinforcing member 6 and the third side 34up due to the thickness of the upright portion 22 of the gantry 2 and the thickness of the holding member 7. is there. Therefore, it is preferable to provide a pedestal 9 at the end of the reinforcing member 6 opposite to the end supported by the gantry 2 to fill a gap between the reinforcing member 6 and the third side 34up. Then, the reinforcing member 6 and the third side 34up are fixed with screws or the like via the pedestal 9. Thereby, the reinforcing member 6 is fixed.

  Therefore, the uppermost corner member 3up is held on the gantry 2 by at least the first holding member 400 and the reinforcing member 6 described above. Further, since the reinforcing member 6 is long and the fixing is simple screwing, the uppermost corner member 3 having the third side 34 of various lengths can be reliably held.

  The preferred embodiment has been described in detail above. However, the present invention is not limited to the above-described embodiment, and various modifications and substitutions can be made to the above-described embodiment without departing from the scope described in the claims. Can be added. For example, although the gantry 2 used for the illustrated solar cell module array is a horizontal rail, the holding mechanism of the present embodiment can also be implemented in a solar cell module array using a vertical rail.
