[0002]

Recently, the practical applications for solar power generation which does not exhaust CO2 which is a main cause of global warming, have been increased. In general, in the solar power generation, a solar power generation panel (may also be referred to as a solar panel or a solar cell panel), in which a plurality of solar cells are arranged and piled-up in a plate shape, is used. In order to increase power generation efficiency using the solar power generation panel, a mount, which supports the solar power generation panel so as to face to the sun, is required.

[0003]

For example, in Patent Document 1, as a mount supporting a solar cell pancl (a solar power generation panel), a mount is disclosed which includes a mounting frame formed in a rectangular frame shape, mounting beams which are juxtaposed at regular intervals inside the mounting frame, and struts which are each joined to four corners of the mounting frame.

In this mount, the solar cell panel is mounted in a mounting space formed by the mounting frame and the mounting beams. The heights of front side struts arc different from the heights of rear side struts. Therefore, the mount can support the solar cell panel in a state where the solar cell panel inclines toward the sun. [Prior Art Document] [Patent Document] .

[Effects of the Invention]

According to the panel supporting mount described in (1), since a configuration, in which a panel mounting lattice that a panel is to be mounted is supported by a plurality of arm members radially extending from a single strut, is adopted, reduction of the number of parts and simplification of the assembly work can berealized. As a result, a cost reduction, and a shortening of a construction period can be realized.

In addition, when the arm members are joined to the strut directly, large loads are locally added to the strut from the arm members, and portions of the strut which are joined to the arm members are deformed partially. As a result, there is a possibility : that the strut is bent. However, according to the panel supporting mount described in (1), since ends of each of the arm members are gathered and fixed in one placeon a pedestal which is provided on an upper end of the strut, it is possible to disperse gathered load to the whole cross section of the strut uniformly and to burden the whole cross section with the gathered load. Therefore, rigidity of the whole panel supporting mount can be increased efficiently. >

According to the panel supporting mount described in (2), in a factory and the : like, the panel mounting lattice, the arm members, the gathering-fixing member, and the second plate material can be assembled integrally as a panel mounting unit beforehand. That is, a construction method, in which the mount is completed by fastening the second plate material of the panel mounting unit to the first plate material by using bolts after the first plate material is joined to the upper end of the strut which is erected on the installation surface by the field work, can be adopted. Therefore, improvement of the construction efficiency (that is, shortening of the construction period) can be realized.

In addition, when the second plate material is fastened to the first plate material by bolts while interposing spacers between the first plate material and the second plate material, a height position of the panel mounting lattice (that is, a height position of the panel) can be adjusted in the field.

According to the panel supporting mount described in (3), when a worker fastens the second plate material of the panel mounting unit by using bolts to the first plate material which is joined to the upper end of the strut, the worker can easily recognize correct mounting direction of the panel mounting unit. Therefore, the : construction efficiency can be further improved. In other words, it is possible to prevent the panel from being fixed in a state where the panel faces an incorrect direction.

In this case, for example, it is preferable to form bolt holes on the first plate material and the second plate material so that the panel mounting unit (that is, the panel) faces the correct direction when the second plate material is fastened to the first plate material by using bolts in a state where the first plate material and the second plate material overlap each other completely.

According to the panel supporting mount described in (4), ends of each of the arm members can be easily fixed by simple configuration in a state where ends of each of the arm members are gathered in one place on the pedestal (second plate material).

Therefore, reduction of the number of parts, and a shortening of a construction period can be further realized. ;

According to the panel supporting mount described in (5), by the field work, it is possible to adjust a position of the fourth plate material in a longitudinal direction of the strut, and a position of the fourth plate material in a direction which is orthogonal to the longitudinal direction of the strut. That is, it is possible to adjust the three- dimensional position of the panel in the field.

Such a position adjustment function is particularly effective in a case where it is necessary to arrange a plurality of the panel supporting mounts orderly so as to be adjacent to each other.

According to the panel supporting mount described in (6), ends of each of the arm members can be easily fixed by simple configuration in a state where ends of each of the arm members are gathered in one place on the pedestal (fourth plate material).

Therefore, reduction of the number of parts and construction time can be further ; realized.

According to the panel supporting mount described in (7), for example, in a case where the panel is a solar power generation panel, it is possible to support the solar power generation panel in a state where the solar power generation panel can receive light of the sun most effectively in the field.

According to the panel supporting mount described in (8), it is not necessary to make a concrete foundation on the installation surface (in this case, the ground) in order to erect the strut. Therefore, reduction of cost and construction time can be further realized.

According to the panel supporting mount described in (9), since a general steel material which is driven into the ground is used as the strut, procurement cost of ; the material can be reduced. :

According to the panel supporting mount described in (10), the panel supporting mount having high rigidity can be obtained by the minimum number of parts. Therefore, the reduction of cost and construction time can be further realized. :

According to the panel supporting mount described in (11) or (12), the rigidity of the panel supporting mount can be further enhanced.

According to the panel supporting mount described in (13), the panel support strength which is obtained by the arm members can be further enhanced. [Brief Description of the Drawing]

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing an overall configuration ofa panel supporting mount 1 according to the present embodiment. FIG. 2 is a front view (a view when viewed from an A direction in FIG 1) of the panel supporting mount 1.

FIG. 3 is a plan view (a view when from a B direction in FIG. 1) of the panel supporting mount 1. FIG. 4 is a side view (a view when from a C direction in FIG. 1) of the panel supporting mount 1.

As shown in FIGS. 1 to 4, the panel supporting mount 1 according to the present embodiment is a mount which is installed on the ground G (installation surface) while supporting a solar power generation panel P thereon as a panel, for example. Moreover, as shown in FIG. 1, a direction orthogonal to the ground G is set to a Z axis direction, and two directions which are orthogonal to the Z axis and are orthogonal to each other on the same plane are set to an X axis direction and a Y axis direction. The A direction is parallel to the Y axis direction, the B direction is parallel to the Z axis direction, and the C direction is parallel to the X axis direction.

The panel supporting mount 1 includes: a panel mounting lattice 10 which is configured to have a plurality of beam members (a first support beam 11 and a second support beam 12 described below) joined in a lattice shape and on which the solar power generation panel P is mounted; a single strut 20 which is erected on the ground :

G; a pedestal 30 which is provided on an upper end of the strut 20; and a plurality of (four in the present embodiment) arm members 40 which are disposed so as to radially :

BN extend from the pedestal 30 and which support the panel mounting lattice 10 from below.

The beam members which constitute the panel mounting lattice 10, include a plurality of (two in the present embodiment) the first support beams 11 (11a and 11b) which are directly supported by the arm members 40 so as to be parallel to each other at a regular interval, and a plurality of (four in the present embodiment) the second support beams 12 (12a, 12b, 12c, and 12d) which are orthogonal to the first support beams 11 and are constructed between the adjacent first support beams 11 so as to be parallel to each other at regular intervals.

The solar power generation panel P is attached to the panel mounting lattice 10 so that a lower surface of the panel P is supported by the second support beam 12.

The number, the dimensions, the materials, and the like of the first support beam 11 and the second support beam 12 may be appropriately determined according to the size, the number of sheets, or the like of the solar power generation panel P which is attached to the panel mounting lattice 10.

Moreover, preferably, the first support beam 11 and the second support beam 12 are steel having a shape in which the beams 11 and 12 can be joined in a state where the beams come into surface contact each other. Accordingly, rigidity of the panel mounting lattice 10 can be increased. For example, as the first support beam 11, when steel (square steel) is used in which a cross-sectional shape orthogonal to a longitudinal direction of the beam 11 is rectangular, and as the second support beam 12, when steel is used in which a cross-sectional shape orthogonal to a longitudinal

Co oo direction of the beam 12 is trapezoid, hexagonal, or rectangular, high rigidity of the panel mounting lattice 10, simplification of an assembling work, and reduction of construction time can be achieved. Of course, the first support beam 11 and the second support beam 12 are not limited to the steel.

Moreover, for example, preferably, the first support beam 11 and the second support beam 12 are joined to each other by bolt fastening using connecting fittings such as L-shaped metal fittings (the connecting fittings are not necessarily necessary).

Accordingly, the rigidity of the panel mounting lattice 10 can be increased, and assembly workability can be improved. Of course, the first support beam 11 and the second support 12 may be joined using other joining methods such as welding.

In addition, when the panel mounting lattice 10 is viewed in a plan view, preferably, the first support beams 11 are positioned at symmetrical positions to each other (that is, line symmetrical positions) while interposing a first center line L1 of the panel mounting lattice 10 therebetween (refer to FIG. 3). That is, preferably, the first support beams 11a and 11b are disposed at positions having equal distances from the first center line L1. Moreover, when the panel mounting lattice 10 is viewed in a plan view, the first center line L1 is a straight line orthogonal to the second support beam 12 ata center position in the longitudinal direction of the second support beam 12.

In addition, when the panel mounting lattice 10 is viewed in a plan view, preferably, the second support beams 12 are positioned at symmetrical positions to : each other while interposing a second center line 12 of the panel mounting lattice 10 therebetween (refer to FIG. 3). That is, preferably, the second support beams 12a and

Lo . : 12d are disposed at positions having equal distances from the second center line L2, and the second support beams 12b and 12c are disposed at positions having equal distances from the second center line L2. Moreover, when the panel mounting lattice 10 is viewed in a plan view, the second center line L2 is a straight line orthogonal to the first support beam 11 at a center position in the longitudinal direction of the first support beam 11.

In the panel mounting lattice 10 having the line symmetrical structure, a weight balance in all directions with an intersection between the first center line L1 and the second center line L2 as the center is improved. Accordingly, a continuous and stable support of the panel mounting lattice 10 (that is, the solar power generation panel P) can be easily performed by the minimum parts such as the single strut 20 described below and four arm members 40 extending from the strut 20.

The panel mounting lattice 10 described above is supported by the arm members 40 from below so that the solar power generation panel P inclines with respect to the ground G (refer to FIG. 4). The inclination angle of the solar power ] generation panel P with respect to the ground G may be set to an angle (for example, 0 to 30°) at which the sunlight can be efficiently received according to a region in which the panel supporting mount 1 is installed.

For example, the strut 20 is a steel pipe pile in which a cross-sectional shape orthogonal to the longitudinal direction of the strut is circular, and is erected on the ground G immediately below the panel mounting lattice 10. Here, when viewed in a plan view, preferably, a center point (a point at which the first center line L1 intersects with the second center line L2) of the panel mounting lattice 10 exits on an extension line of a center axis of the strut 20 (refer to FIG. 3).

In this way, the central axis of the strut 20 coincides with the center point of the panel mounting lattice 10, and thus, as described above, the continuous and stable support of the panel mounting lattice 10 having an improved weight balance can be easily performed. However, in a design and a construction of the panel supporting mount, it is difficult for the central axis of the strut 20 to coincide with the center point of the panel mounting lattice 10 completely. Therefore, the central axis of the strut 20 should coincide with the center point of the panel mounting lattice 10 within an allowable range (tolerance).

Moreover, as the present embodiment, when an installation surface of the panel supporting mount 1 is the ground G, preferably, lower portion of the strut 20 is directly embedded in the ground (refer to FIGS. 2 and 4). Accordingly, it is not necessary to provide a concrete foundation for fixing the strut 20 on the ground surface or in the ground. Of course, it is not necessarily necessary to directly embed the strut in the ground, and according to the situation, the concrete foundation for fixing the strut 20 may be provided. 20

Moreover, the strut 20 is not limited to the steel pipe piles having the circular shape described above, and may be a steel pipe pile having a polygonal cross-sectional shape, an H-steel pipe, a steel sheet pile, or the like. In this way, since the steel generally embedded in the ground is used as the strut 20, provision costs of the members can be decreased. Of course, the strut 20 is not limited to the above- described steel.

The pedestal 30 is provided on the upper end of the strut 20, and includes a gathering-fixing member 31 (the details of the gathering-fixing member will be described below with reference to FIGS. 5 to 8) which gathers ends of each of four arm members 40 in one place and which fixes the ends of each of four arm members 40 in the place. Four arm members 40 (41, 42, 43, and 44) are disposed so as to radially extend from the gathering-fixing member 31 of the pedestal 30 in a plan view, and support the panel mounting lattice 10 from below.

Specifically, among four arm members 40, two arm members 41 and 42 are connected to the first support beam 11a by using a jointing method which is welding, bolt fastening, or the like. Other two arm members 43 and 44 are connected to the first support beam 11b by using a jointing method which is welding, bolt fastening, or the like. That is, the first support beam 11a is supported by the arm members 41 and 42 in a state where the first support beam 11a is inclined. The first support beam 11b is supported by the arm members 43 and 44 in a state where the first support beam 11b ; is inclined. Thereby, the panel mounting lattice 10 (that is, the solar power generation panel P) is supported in a state where the panel mounting lattice 10 is inclined (refer to

FIG. 4).

It is preferable that each of the arm members 40 is a steel material having a closed cross section (for example, a polygonal shape section such as a square shape section) or an opened cross section (for example, a groove shape section, a C-shape section, a hat shape section, and the like) as a cross section which is orthogonal to a longitudinal direction of the arm member 40. In addition, the hat shape section indicates a cross section including: a pair of side wall portions opposite to each other; a connecting wall portion which connects ends of the side wall portions to each other; and flange portions which extend from the other ends of the side wall portions in opposite directions. Of course, the arm members 40 are not limited to the above- described steel.

Hereinafter, the details of the pedestal 30 will be described with reference to

FIGS. 5to 8.

FIG. 5 is a perspective view showing an overall configuration of the pedestal 30. FIG. 61s a front view (a view when viewed from the A direction in FIG. 5) of the pedestal 30. FIG. 7 is a plan view (a view when viewed from the B direction in FIG. 5) of the pedestal 30. FIG. 8 is a side view (a view when viewed from the C direction in FIG. 5) of the pedestal 30.

The pedestal 30 includes: a first plate material 32 which is joined to the upper end of the strut 20 in a state where an upper surface of the first plate material 32 is orthogonal to a longitudinal direction of the strut 20; and a second plate material 33 which is fastened to the first plate material 32 by bolts while interposing spacers 34 between the first plate material 32 and the second plate material 33 in a state where an upper surface of the second plate material 33 is orthogonal to the longitudinal direction of the strut 20, in addition to the gathering-fixing member 31.

Preferably, the first plate material 32 is joined to the upper end of the strut 20 by a strong joining method such as welding, but may be joined by other joining methods. The second plate material 33 is fastened to the first plate material 32 by four bolts 35. However, when height adjustment is unnecessary, the spacers 34 may

Dberemoved. In addition, when considering the following reason, it is preferable that the first plate material 32 and the second plate material 33 are rectangular plate materials having the same dimensions. Of course, the shape of the first plate material 32, the shape of the second plate material 33, the dimensions of the first plate material 32, and the dimensions of the second plate material 33 are not limited to the above- described shape and dimensions.

The gathering-fixing member 31 is provided on the upper surface of the second plate material 33. The gathering-fixing member 31 includes a plurality of (two in the present embodiment) third plate materials 31a and 31b which are erected on the upper surface of the second plate material 33 so as to intersect at one place each : other. The ends (opposite ends of ends connected to the first support beams 11) of each of the arm members 40 are joined to both surfaces of the third plate material 31a by a strong joining method such as welding.

Specifically, the arm members 41 and 43 are joined to two areas partitioned by the third plate material 31b on one surface of the third plate material 31a. The arm members 42 and 44 are joined to two areas partitioned by the third plate material 31b : on the other surface of the third plate material 31a. In addition, joints of the arm : members 40 are not limited to that. The arm members 40 may be joined to the third plate material 31b, or may be separately joined to both the third plate materials 31a and

Here, it is preferable that an intersection of two third plate materials 31a and 31b exists on an extended line of the central axis of the strut 20 in a plan view (refer to

FIG. 7). From this, as described above, the continuous and stable support of the panel mounting lattice 10 having an improved weight balance can be easily performed.

However, in a design and a construction of the panel supporting mount, it is difficult for the intersection of the third plate materials 31a and 31b to coincide with the central axis of the strut 20 completely. Therefore, the intersection of the third plate materials 31a and 31b should coincide with the central axis of the strut 20 within an allowable range (tolerance).

As described above, according to the panel supporting mount 1 of the present embodiment, since a configuration, in which the panel mounting lattice 10 that the solar power generation panel P is to be mounted is supported by four arm members 40 radially extending from the single strut 20, is adopted, reduction of the number of parts and simplification of the assembly work can be realized. Asa result, the cost reduction, and the shortening of the construction period can be realized.

In addition, when the arm members 40 are joined to the strut 20 directly, large loads are locally added to the strut 20 from the arm members 40, and portions of the strut 20 which are joined to the arm members 40 are deformed partially. As a result, there is a possibility that the strut 20 is bent. However, according to the panel supporting mount 1 of the present embodiment, since ends of each of the arm members 40 are gathered and fixed in one place on the pedestal 30 which is provided on the upper end of the strut 20, it is possible to disperse gathered load to the whole cross section of the strut 20 uniformly and to burden the whole cross section with the gathered load. Therefore, rigidity of the whole panel supporting mount 1 can be increased efficiently.

Additionally, according to the panel supporting mount 1 of the present embodiment, in a factory and the like, the panel mounting lattice 10, the arm members 40, the gathering-fixing member 31, and the second plate material 33 can be assembled integrally as a panel mounting unit beforehand. That is, a construction method, in which the mount is completed by fastening the second plate material 33 of the panel mounting unit to the first plate material 32 by using bolts after the first plate material 32 is joined to the upper end of the strut 20 which is erected on the installation surface (ground G) by the field work, can be adopted. Therefore, improvement of the construction efficiency (that is, the shortening of the construction period) can be realized.

In addition, the second plate material 33 is fastened to the first plate material 32 by bolts while interposing spacers 34 between the first plate material 32 and the second plate material 33. Thereby, a height position of the panel mounting lattice 10 (that is, a height position of the solar power generation panel P) can be adjusted in the field.

Additionally, according to the panel supporting mount 1 of the present embodiment, since the first plate material 32 and the second plate material 33 are rectangular plate materials having the same dimensions, when a worker fastens the second plate material 33 of the panel mounting unit by using bolts to the first plate material 32 which is joined to the upper end of the strut 20, the worker can easily i recognize correct mounting direction of the panel mounting unit. Therefore, the construction efficiency of the panel supporting mount 1 can be further improved. In other words, it is possible to prevent the solar power generation panel P from being fixed in a state where the solar power generation panel P faces an incorrect direction.

In this case, for example, it is preferable to form bolt holes on the first plate material 32 and the second plate material 33 so that the panel mounting unit (that is, the solar power generation panel P) faces the correct direction when the second plate material 33 is fastened to the first plate material 32 by using bolts in a state where the first plate material 32 and the second plate material 33 overlap each other completely.

Additionally, according to the panel supporting mount 1 of the present embodiment, ends of each of the arm members 40 can be easily fixed by simple configuration in a state where ends of each of the arm members 40 are gathered in one place on the pedestal 30. Therefore, the reduction of the number of parts, and the shortening of the construction period can be further realized.

Additionally, according to the panel supporting mount 1 of the present embodiment, since the strut 20 is embeded in the ground directly, it is not necessary to make a concrete foundation on the installation surface (in this case, the ground G) in order to erect the strut 20. Therefore, the cost reduction, and the shortening of the construction period can be further realized. _21-

As described above, one embodiment of the present invention is described.

However, the present invention is not limited to the embodiment, and for example, i may include the following modifications.

Next, Example of the present invention will be described. However, conditions in Example are condition examples adopted to confirm feasibility and effects of the present invention, and the present invention is not limited to the condition examples. In the present invention, various conditions can be adopted as long as the object of the present invention is achieved without departing from the gist of the present invention.

In Example, a panel in which a vertical length was 990 mm and a lateral length was 1650 mm was used as a solar power generation panel, 12 panels (3 columns x 4 rows in the lateral direction) per one module were attached to a panel mounting lattice. In Example, a wind pressure for a wind load design was set to 2400 N/mm?>.

Moreover, in Example, as the second support beam, a steel pipe (upper side: 100 mm, lower side: 40 mm, height: 75 mm, height of inclined side: 45 mm, and plate thickness: 1.6 mm) was used in which the cross-sectional shape orthogonal to the longitudinal direction was hexagonal as shown in FIG. 12.

Moreover, in Example, as the first support beam, a steel pipe (cross-sectional dimension: 125 mm x 75 mm, and plate thickness: 1.6 mm) was used in which the cross-sectional shape orthogonal to the longitudinal direction was a quadrangle (a rectangle).

Using the first support beams and the second support beams, a panel mounting lattice was manufactured in which a vertical length was 3100 mm and a lateral length was 3100 mm when viewed from a plan view.

In addition, in Example, as the strut, a steel pipe pile (diameter: 114.3 mm and plate thickness: 2.8 mm) was used in which the cross-sectional shape orthogonal to the longitudinal direction were circular.

In addition, in Example, as the arm member, a steel pipe (cross-sectional dimension: 50 mm x 50 mm, and plate thickness: 2.3 mm) was used in which the cross-sectional shape orthogonal to the longitudinal direction was a quadrangle.

In the field, using the above-described members, a panel supporting mount for supporting a solar power generation panel was assembled so that the inclination angle with respect to the ground was 10°.

It took 0.5 days per one module from an assembly start to construction completion. Since a general construction period (for example, in the case of Patent

Document 1) is 10 days, according to the present invention, it was confirmed that the construction period could be remarkably shortened. [Industrial Applicability] :

According to the present invention, a panel supporting mount can be provided in which the configuration and the assembling work are simple, the cost is low, the construction period is short, and the panel support strength is excellent. Therefore, according to the present invention, remarkable industrial effects can be expected.
