Here, FIG. 2 is a partial sectional view taken along line II-II in FIG. 1. FIG. 3 is a partial cross-sectional view taken along line III--III in FIG. FIG. 4 is a partial cross-sectional view taken along the line IV--IV in FIG. FIG. 5 is a partially enlarged view of the portion surrounded by the dashed-dotted ellipse E in FIG. 1, viewed from the front.

Each of the base rails 103_1 to 103_5 is an elongated hollow rod-shaped member in which a guide groove 107 extends in the left-right direction, and is made of metal, for example. The base rails 103_1 to 103_5 are arranged at the installation location P so that their longitudinal directions are parallel to each other and face in the left-right direction.

In the description of this embodiment, base rails 103_1 to 103_5 will be referred to in order from the base rail disposed at the front, but if these are not particularly distinguished, they will be referred to as base rail 103. Note that one or more base rails 103 may be provided on the solar power generation panel mount 102 depending on the number, arrangement method, size, etc. of the solar power generation panels 101 included in the solar power generation device 100.

The details of the arrangement method of the panel pressing member 105 corresponding to the base rail 103_2 are the same as those in which the arrangement method of the panel pressing member 105 corresponding to the base rail 103_4 described above is replaced with the base rail 103_2. In order to simplify the explanation, a detailed explanation of the panel pressing member 105 arranged in association with the base rail 103_2 will be omitted.

As shown in FIG. 6B, the front three photovoltaic panels 101 are placed on the base rails 103_1 to 103_3 (step 34).

Specifically, the installation worker slides the three front photovoltaic panels 101 from the front to the rear in an appropriate order.

As shown in FIG. 6B, the panel pressing member 105 corresponding to the frontmost base rail 103_1 is arranged (step 35). That is, the panel pressing member 105 is arranged above the slide member 104 attached to the base rail 103_1.

Specifically, as shown in FIG. 1, six end pressing members 105b are arranged above each of the six slide members 104 attached to the base rail 103_1. Each of the end holding members 105b orients the second panel positioning portion 123 generally in the left-right direction so that the second extending portion 124 extends rearward, and the second bolt hole 125, the nut hole 115, and The nuts 116 are arranged vertically.

As shown in FIG. 6A, the bolt 106 temporarily fastened in step 3 is tightened to the nut 116 using an appropriate tool, thereby fastening the vertically associated slide member 104 and panel holding member 105. (Step 4).

Specifically, by tightening the bolt 106 to the nut 116, the slide member 104 and the panel pressing member 105, which are vertically matched in step 3, are fastened by screw action. Further, as described above, the slide member 104 is locked by the locking portion 110 so as to limit upward movement. As a result, the outer edge of the solar power generation panel 101 is clamped between the first extension part 120 or the second extension part 124 and the locking part 110 by the clamping force based on the screw action. The clamping force here means a force in a direction in which the first extending portion 120 or the second extending portion 124 and the locking portion 110 approach each other.

According to the solar power generation device installation method described so far, the solar power generation device 100 is installed at the installation location P, with the solar power generation panel 101 firmly held so as not to be blown away by the wind.

(action/effect)
As described above, the solar power generation panel mount 102 according to one embodiment includes a base rail 103, a plurality of slide members 104, a plurality of panel holding members 105, and a plurality of bolts 106 as fastening members. Equipped with.

The base rail 103 is formed with a guide groove 107 that extends in the longitudinal direction, and the guide groove 107 opens upward through an opening 112 that has a width narrower than the width of the guide groove 107 and extends in the longitudinal direction. Each of the slide members 104 has a width larger than the width of the opening 112, and is fitted into the guide groove 107 of the base rail 103 so as to be slidable in the longitudinal direction. The plurality of panel holding members 105 are arranged above each of the plurality of slide members 104 and extend above the base rail in order to sandwich the outer edge of the solar power generation panel 101 between the base rail 103 and the outer edge of the solar power generation panel 101 . The plurality of bolts 106 move the slide members 104 and panel holding members 105 that are vertically matched so that the outer edge of the solar power generation panel 101 is held between the base rail 103 and the plurality of panel holding members 105. conclude.

According to such a solar power generation panel mount 102, the base rails 103 may be installed at the installation location P at intervals according to the size and arrangement direction of the solar power generation panel 101. Thereby, the slide member 104 moves along the guide groove 107 and is arranged at a position corresponding to the size and arrangement direction of the solar power generation panel 101. Moreover, the panel pressing member 105 and the bolt 106 may be arranged in correspondence with the position of the slide member 104.

In this way, by installing the base rail 103 according to the size and arrangement direction of the solar power generation panel 101, the other members 104, 105, and 106 can be easily positioned using the guide rails. Therefore, in order to install the solar power generation panel 101, if general construction knowledge and skills are available, knowledge and skills specific to the solar power generation panel mount 102 are almost not required. Therefore, it becomes possible to easily install the solar power generation panel.

Furthermore, if the outer edge of the solar power generation panel 101 is located between the first extension part 120 or the second extension part 124 and the locking part 110, the panel holding member 105 and the slide member 104 are held together by the bolt 106. By fastening, the outer edge of the solar power generation panel 101 can be held.

Therefore, when viewed from above, the longitudinal direction of the guide groove 107 and the side surface of the solar power generation panel 101 may be in directions that obliquely intersect with each other at a desired angle. Even in such a case, by orienting the first panel positioning part 119 or the second panel positioning part 123 in the direction along the side surface of the solar power generation panel 101, the first extension part 120 or the The outer edge of the solar power generation panel 101 can be held between the second extension part 124 and the locking part 110.

Using the solar power generation panel mount 102 according to the embodiment, the solar power generation panel is mounted so that the side surface of the solar power generation panel 101 is oriented in a direction diagonally intersecting the longitudinal direction of the guide groove 107 when viewed from above. An example of installing 101 is shown in the plan view of FIG.

FIG. 7 is a plan view showing an example in which the solar power generation device 100 is installed at the installation location Q on the roof surface of a roof with ridges, which is different from the embodiment. This photovoltaic power generation device 100 has a configuration made of substantially the same members as those of the embodiment. At the installation location Q shown in FIG. 7, protrusions 127 that protrude upward and extend in the left-right direction are provided on a generally flat roof surface at approximately equal intervals in the front-rear direction. The height of the protrusion 127 is lower than the height of the base rail 103.

Depending on the solar radiation conditions at the installation location Q, it may be desirable to arrange the solar power generation panel 101 in a direction in which the side surface of the solar power generation panel 101 diagonally intersects the protrusion 127 when viewed from above. In such a case, if the base rail 103 is arranged so that the side surface of the solar power generation panel 101 and the longitudinal direction of the guide groove 107 are parallel or perpendicular to each other when viewed from above, the base rail 103 will intersect with the protrusion 127. I will do it. The protrusion 127 creates a gap between the bottom surface 111 and the flat part of the installation location Q, making it difficult to stably arrange the base rail 103.

In the solar power generation panel mount 102 according to the present embodiment, as described above, the longitudinal direction of the guide groove 107 and the side surface of the solar power generation panel 101 do not need to be parallel or at right angles. Therefore, even if the installation location Q includes unevenness such as the protrusion 127, the base rail 103 can be stably arranged and the side surface of the solar power generation panel 101 can be oriented in a desired direction. can be easily done. Therefore, it becomes possible to easily install the solar power generation panel 101 according to the shape of the installation locations P and Q, solar radiation conditions, and the like.

According to this embodiment, the base rail 103 includes a bottom plate portion 108, two side wall portions 109, and two locking portions 110. The bottom plate portion 108 extends in the longitudinal direction of the guide groove 107. The two side walls 109 extend upward from each end of the bottom plate 108 in the width direction. The two locking portions 110 form an opening 112 by extending from the upper ends of the two side wall portions 109 in a direction approaching each other.

Such a base rail 103 can be easily manufactured by bending a rectangular flat metal plate or cutting a rectangular bar-shaped member. Therefore, it becomes possible to easily manufacture a mount for a solar power generation panel.

According to this embodiment, the plurality of panel pressing members 105 include an intermediate pressing member 105a and an end pressing member 105b.

The intermediate holding member 105a includes a first opposing plate portion 118, a first panel positioning portion 119, and a first extending portion 120. The first opposing plate portion 118 includes a pair of first side portions that are parallel to each other, and is arranged to include a portion that vertically faces the slide member 104 through the opening 112. The first panel positioning section 119 extends upward from each of the first sides of the first opposing plate section 118 . The first extending portions 120 extend from the upper end portions of each of the first panel positioning portions 119 in a direction away from each other and extend above the base rail 103 .

With such an intermediate holding member 105a, by arranging the side surface of the solar power generation panel 101 close to the first panel positioning portion 119, the arrangement direction and position of the solar power generation panel 101 can be easily adjusted. You can decide. Therefore, it becomes possible to easily install the solar power generation panel 101.

Further, in the intermediate holding member 105a, two pairs of first panel positioning portions 119 and first extension portions 120 are included for one first opposing plate portion 118. Thereby, two solar power generation panels arranged in different directions can be sandwiched between the base rail 103 and one intermediate holding member 105a via the intermediate holding member 105a. Therefore, it becomes possible to easily install a plurality of solar power generation panels 101 with a simple configuration.

Further, the intermediate holding member 105a can be easily formed by bending a rectangular flat metal plate or the like. Therefore, it becomes possible to easily manufacture the solar power generation panel mount 102.

The end holding member 105b includes a second opposing plate portion 122, a second panel positioning portion 123, and a second extending portion 124. The second opposing plate portion 122 includes at least one second side portion, and is arranged to include a portion that vertically faces the slide member 104 via the opening 112. The second panel positioning portion 123 is a flat plate-shaped portion extending upward from one of the second sides of the second opposing plate portion 122 . The second extending portion 124 extends from the upper end of the second panel positioning portion 123 in a direction away from the second opposing plate portion 122 and extends above the base rail 103.

With such an end holding member 105b, by arranging the side surface of the solar power generation panel 101 close to the second panel positioning section 123, the direction and position of the solar power generation panel 101 can be easily adjusted. can be decided. Therefore, it becomes possible to easily install the solar power generation panel 101.

Moreover, in the end holding member 105b, the second panel positioning part 123 and the second extending part 124 included in one second opposed plate part 122 are a pair. Therefore, the structure can be made simpler than the intermediate holding member 105a.

In many cases, a plurality of solar power generation panels 101 are installed as illustrated in FIG. It is simply placed. By employing the edge holding member 105b to hold the solar power generation panel at a location where the solar power generation panel 101 is arranged only in one direction with respect to the panel holding member 105, the solar power generation panel The configuration of the pedestal 102 can be simplified. Therefore, it becomes possible to install a solar power generation panel with a simple configuration.

Furthermore, the end holding member 105b can be easily formed by bending a rectangular flat metal plate or the like. Therefore, it becomes possible to easily manufacture the solar power generation panel mount 102.

According to this embodiment, the fastening member is a bolt 106, and a nut 116 is fixed to the slide member 104. Moreover, the panel holding member 105 includes a first bolt hole 121 or a second bolt hole 125 as a bolt hole into which the shaft portion of the bolt 106 is inserted.

In this way, one of the bolt 106 and the nut 116 is a fastening member, and the other is provided on the slide member 104, thereby preventing the bolt 106 and the nut 116 from slipping when tightening each other and applying sufficient tightening force. Therefore, the outer edge of the solar power generation panel 101 can be easily clamped with sufficient clamping force. Moreover, since the number of parts is reduced by not making the nut 116 a separate member, assembly of the solar power generation panel mount 102 becomes easier. Therefore, it becomes possible to easily install the solar power generation panel 101.

According to this embodiment, the guide groove 107 and the opening 112 are open at both ends in the longitudinal direction. Thereby, the slide member 104 can be easily fitted into the guide groove 107 from either end in the longitudinal direction. Therefore, the solar power generation panel mount 102 can be easily assembled, and the solar power generation panel 101 can be easily installed.

According to this embodiment, the solar power generation panel mount 102 further includes a fixing member 117 that fixes the slide member 104 to the base rail 103 in order to prevent sliding movement along the guide groove 107. Since the slide member 104 and the panel pressing member 105 are fixed to the base rail 103 by such a fixing member 117, the position of the solar power generation panel 101 can be fixed more firmly. Therefore, it becomes possible to hold the solar power generation panel 101 even more firmly.

The solar power generation panel mount 102, the solar power generation device 100, and the method of installing the solar power generation device according to one embodiment of the present invention have been described above. The solar power generation panel mount 102, the solar power generation device 100, and the method of installing the solar power generation device according to the present invention are not limited to the above-described embodiments, and may be modified as follows, for example. good.

(Modification 1)
In the embodiment, an example in which the solar power generation device 100 is installed at the installation location P has been described. Furthermore, it has been explained that the solar power generation device 100 configured from members generally similar to those of the embodiment can be installed even at the installation location Q including the protrusion 127. However, the installation location is not limited to these. The installation location may be, for example, a roof surface such as a folded plate roof, a vertical thatched roof, or a flat roof. Further, for example, the installation location is not limited to the roof surface, but may be an outer wall surface of a building or structure.

Here, in the installation location Q described with reference to FIG. 7, an example is shown in which the height of the protrusion 127 is lower than the height of the base rail 103. However, as shown in FIGS. 8A and 8B, the installation location R has a flat flat part 228 that extends in a long and narrow strip shape in the left-right direction, and a flat part 228 that extends upward from the flat part 228 at a height that exceeds the height of the base rail 103. It may include a protrusion 229 that protrudes and has a curved upper surface.

In such a case, even if the base rail 103 is placed on the flat portion 228, it is difficult to place the solar power generation panel 101 on the base rail 103 because the protruding portion 229 protrudes greatly. Further, if the upper surface of the protrusion 229 is curved, it is difficult to arrange the base rail 103 with a flat bottom surface 111 on the protrusion 229 as in the embodiment. Although a base rail having a curved bottom surface to match the shape of the protrusion 229 may be prepared, in this case, it takes time and effort to manufacture the base rail according to the shape of the installation location R.

In such a case, as shown in FIGS. 8A and 8B, the solar power generation panel mount 202 may further include an auxiliary member 230 interposed between the installation location R and the base rail 103.

Here, FIG. 8A is a plan view of a solar power generation device 200 according to Modification 1. FIG. 8B is a partial cross-sectional view taken along line VIII_B-VIII_B in FIG. 8A. In this modification, the solar power generation device 200 is configured similarly to the solar power generation device 100 according to the embodiment, except that the solar power generation panel mount 202 further includes an auxiliary member 230.

The auxiliary member 230 according to this modification is a tube having a generally rectangular parallelepiped outer shape, and includes a lower fixing part 231 , an upper fixing part 232 , and a connecting part 233 . The length of the auxiliary members 230 and the number of auxiliary members 230 to be arranged may be determined as appropriate depending on the shape of the installation location R, the length of the base rail 103, and the like.

The lower fixing part 231 and the upper fixing part 232 are generally rectangular plate-shaped parts that are parallel to each other. The lower fixing portion 231 is fixed to the flat portion 228 at the installation location R using an adhesive, screws, bolts, etc. (not shown). The upper fixing part 232 is provided at a position separated from the lower fixing part 231, and the base rail 103 is fixed with adhesive, screws, bolts, etc. (not shown).

The figure shows a cross section of the base rail 303 and a side surface of the slide member 304 according to this modification as seen from the longitudinal direction of the guide groove 307.

As shown in FIG. 9, the solar power generation device and solar power generation panel mount according to this modification includes a base rail 303 and a slide member 304 instead of the base rail 103 and slide member 104 according to the embodiment. . Except for these points, each of the solar power generation device and the solar power generation panel mount according to the present modification is configured similarly to the solar power generation device 100 and the solar power generation panel mount 102 according to the embodiment. Ru.

As shown in FIG. 9, the base rail 303 according to this modification includes a bottom plate portion 108 similar to the embodiment and two side wall locking portions 334. The base rail 303 can be manufactured, for example, by cutting a generally rectangular parallelepiped elongated bar-shaped member made of metal, resin, or the like.

As shown in FIG. 9, the two side wall locking portions 334 are approximately right triangular portions that are arranged symmetrically in the width direction (that is, symmetrically in the front-rear direction in FIG. 9) when viewed from the longitudinal direction. The outer surface of each of the two side wall locking portions 334 is a generally rectangular plane that extends upward from each side of the bottom plate portion 108 in the width direction generally perpendicularly to the bottom plate portion 108 . Furthermore, the inner surfaces of the two side wall locking portions 334 are generally rectangular planes that slope toward each other toward the top.

The inner surfaces of each of the bottom plate portion 108 and the two side wall locking portions 334 define a guide groove 307 that has a generally trapezoidal shape and extends in the longitudinal direction. Further, the opening 312 formed by the two side wall locking portions 334 extends in the left-right direction with a width narrower than the width of the guide groove 307.

The upper plate part 313 has generally the same configuration as the upper plate part 113, except that the upper plate part 113 according to the embodiment has a width shorter than that of the upper plate part 113.

The two hanging portions 314 are portions that extend downward from each end in the width direction (front-back direction in FIG. 9) of the upper plate portion 313 so that the distance between them becomes wider as they go downward. Except for the angle with respect to the upper plate part 313 when viewed from the left and right directions, the hanging part 314 is configured in the same manner as the hanging part 114 according to the embodiment.

Also in this modification, the width of the slide member 304 is larger than the width of the opening 312, similarly to the embodiment. Here, the width of each slide member 304 is the length in the front-rear direction when it is fitted into the guide groove 107. Therefore, upward movement of the slide member 304 is restricted by being locked by the side wall locking portion 334. Therefore, the slide member 304 can slide in the left and right direction along the guide groove 307 without slipping out upward from the guide groove 307, and the slide member 304 can slide in the left and right direction along the guide groove 307 without slipping out upward from the guide groove 307. It becomes possible to pinch the outer edge of the photovoltaic panel 101.

Although FIG. 9 shows an example in which the intermediate holding member 105a is applied to the slide member 304, the end holding member 105b may also be applied to the sliding member 304 in the same manner as in the embodiment.

In the panel pressing member 105 according to the embodiment, an example has been described in which both the first opposing plate portion 118 and the second opposing plate portion 122 have a rectangular flat plate shape. However, a portion corresponding to the first opposing plate portion 118 or the second opposing plate portion 122 of the panel holding member, that is, the upper surface of the locking portion 110 is arranged, and is connected to the upper plate portion 113 of the slide member 104 through the opening 112. The shapes of the parts arranged on the upper surfaces of the locking parts 110 that are vertically opposed to each other may be changed as appropriate. A modification regarding the panel pressing member will be described below as modification 3.

The third opposing plate portion 435 is a circular flat plate portion that is opposed to the slide member 104 through the opening 112. The third opposing plate portion 435 includes a third bolt hole portion 438 that forms a hole penetrating in the vertical direction approximately at the center.

The third panel positioning portion 436 is a cylindrical portion extending upward from the outer peripheral portion of the third opposing plate portion 435. Note that the third panel positioning portion 436 is not limited to a cylindrical shape, and may be, for example, a hollow truncated cone shape whose diameter decreases or expands upward.

The third extending portions 437 are portions that each extend outward from the upper end of the third panel positioning portion 436 and above the base rail, and are hollow annular (so-called donut-shaped) flat plates.

Similarly to the intermediate holding member 105a, the panel holding member 405 according to this modification is arranged between adjacent solar power generation panels 101, so that the outer edge of each of the solar power generation panels 101 can be can be held between the base rail 103 and the base rail 103. Therefore, in the embodiment, by employing the panel pressing member 405 instead of the intermediate pressing member 105a, the same effects as in the embodiment can be achieved.

In the embodiment, an example has been described in which the plurality of panel pressing members 105 include the intermediate pressing member 105a and the end pressing member 105b. However, the configuration of the plurality of panel pressing members included in the solar power generation panel mount 102 is not limited to this. For example, the panel pressing member may include an intermediate pressing member 105a, an end pressing member 105b, and a panel pressing member 405. Further, for example, the panel pressing member may be composed of the end pressing member 105b and the panel pressing member 405. Further, for example, the panel pressing member may be composed of only the intermediate pressing member 105a, only the end pressing member 105b, or only the panel pressing member 405.

In the embodiment, an example in which the fastening member is the bolt 106 has been described, but the fastening member is not limited to this.

For example, the fastening member may be a nut. In this case, instead of the nut 116, the shaft portion of the bolt may be fixed to the first opposed plate portion 118 so as to protrude upward. Also in this case, the shaft portion of the bolt is preferably disposed so as to penetrate into the first bolt hole 121 or the second bolt hole 125, as in the present embodiment.

For example, the fastening member may be a clamping tool such as a clip that uses elastic force to clamp the upper plate portion 113 of the slide member 104 and the first opposing plate portion 118 of the panel holding member 105 between the left end and the right end. You can. In this case, the nut 116 and the nut hole 115 may not be provided.

Even in these modified examples, a state in which a force is applied to the vertically associated slide member 104 and panel presser member 105 in a direction that causes them to approach each other is maintained. Therefore, the slide member 104 and panel presser member 105 that are vertically associated with each other are fastened so as to sandwich the outer edge of the solar power generation panel 101 between the base rail 103 and each of the plurality of panel presser members 105. . Therefore, substantially the same effects as the embodiment are achieved.
