JP 2012-52346 A

  A large amount of force is applied to the support column and the horizontal rail of the solar cell panel frame installed in the snowy area due to the load of snow accumulated on the solar cell panel. In order to disperse this force and increase the structural strength of the solar cell panel mount, a structure is known in which a brace is added to the mount.

  In many conventional solar cell panel mounts, the brace is fixed to the column through a brace fixing bracket attached to the middle part of the column. In this fixing method, since the connection portion between the support column and the foundation is separated from the brace fixing bracket, the bending moment of the support column is increased. For this reason, when the support column is made of a material having a relatively low strength such as an aluminum alloy, it is difficult to install the solar cell panel mount in an area where the load on the support column is large and the amount of vertical snow is large.

  This invention is made | formed in view of such a subject, The objective is to provide the technique which suppresses the bending moment added to the support | pillar of a solar cell panel mount frame.

  In order to solve the above-described problems, an aspect of the present invention includes a column mounting bracket fixed to a foundation, a column fixed to the column mounting bracket, and a vertical rail that is installed on the column and can support a solar panel. And / or a horizontal rail, a brace that connects one upper part and the other lower part of adjacent struts, and a brace fixing bracket that connects a lower end of the brace to a strut mounting bracket.

  According to this aspect, it is possible to suppress the moment generated in the column, and to reduce the bending strength required for the column, compared to connecting the brace fixing bracket to the middle of the column. For this reason, a solar cell panel mount can be manufactured using material (for example, aluminum alloy) whose intensity is lower than before.

  The strut mounting bracket, the strut and the brace fixing bracket may be fastened together using a common bolt. According to this, the number of parts can be reduced and the efficiency of the construction work of the solar cell panel mount can be increased.

  In the brace fixing bracket, the hole through which the bolt connecting the brace is inserted may be located above the hole through which the common bolt is inserted. According to this, it is possible to fasten the column mounting bracket, the column and the brace fixing bracket together with the brace temporarily fixed to the brace fixing bracket.

  The post mounting bracket may have two standing walls extending in parallel with each other and the supporting column interposed therebetween, and the breath fixing bracket may have two opposing walls extending perpendicular to the standing wall and interposing the breath. According to this, it is advantageous to counter the bending moment in the opening direction of the column. Further, by making the extending direction of the walls of the support bracket and the brace fixing bracket perpendicular to each other, it is possible to further fix another brace (for example, frontage breath) to the support bracket.

  The breath may extend in the depth direction. With this brace, the load applied to the underwater side rail can be distributed to the underwater foundation.

  The post mounting bracket and / or the brace fixing bracket may be an extruded product. Thereby, a support | pillar attachment metal fitting and / or a brace fixing metal fitting can be manufactured cheaply.

  An upper column mounting bracket for fixing the column and the horizontal rail may be further provided, and the upper end of the brace may be coupled to the upper column mounting bracket. According to this, even if the thickness of the column is relatively small, it is possible to connect the breath to the column.

  According to the present invention, it is possible to suppress a bending moment applied to the support of the solar cell panel mount.

It is a schematic perspective view of the solar cell apparatus using the solar cell panel mount which concerns on one Embodiment of this invention. It is the figure which abbreviate | omitted or permeate | transmitted some solar cell panels of the solar cell apparatus of FIG. It is an expansion perspective view of a set of water upper column and water lower column adjacent to each other in the depth direction. It is a figure which expands further and shows the attachment part of a water-side support | pillar and a foundation. FIG. 4 is a side view of the water upper column and the water column of FIG. 3. It is an expansion perspective view of the upper part of a water column.

  FIG. 1 is a schematic perspective view of a solar cell device 100 using a solar cell panel mount 1 according to an embodiment of the present invention.

  The solar cell device 100 includes a plurality of solar cell panels 2 arranged vertically and horizontally, and a solar cell panel mount 1 that holds the solar cell panel in a predetermined posture at a predetermined position. The solar cell panel 2 is a plate-like member as a whole in which a large number of solar cell elements are arranged on the glass plate surface, and is configured to generate electric power by irradiation with sunlight.

  As can be seen from FIG. 1, the solar cell panel mount 1 is such that one side of the support column is low and the other side is high, and supports the solar cell panel 2 inclined at a predetermined angle with respect to the horizontal plane. This angle is determined from the irradiation angle and direction of sunlight, the relationship with the adjacent solar cell device, and the like, and is usually 10 ° to 35 °.

  The inclination support of the solar cell panel 2 also has the purpose of dropping water and snow on the panel downward due to the inclination. In the following description, the lower side of the solar cell panel mount 1 is referred to as a “waterside” and the higher side is referred to as a “waterside”. In addition, two directions indicated by arrows in the figure are referred to as “frontage direction” and “depth direction”.

  FIG. 2 is a diagram in which a part of the solar cell panel 2 of the solar cell device 100 of FIG. 1 is omitted or transmitted.

  The solar cell panel mount 1 includes a foundation 4, a water-side support column 10, a water-side support column 12, a vertical rail 20, a horizontal rail 22, a depth brace 14, and a frontage brace 16.

  The foundation 4 is a member that serves as a foundation when the solar cell panel mount 1 is installed on the site, and is formed of, for example, block-shaped concrete. The lower part of the foundation 4 is buried in the ground, and the upper part is installed so as to protrude from the ground surface. In the illustrated example, the foundations 4 are provided in three rows in the opening direction of the solar cell panel mount 1 and in two rows in the depth direction, and are installed at a predetermined interval.

  The upper water column 10 and the lower water column 12 are long rod-like members that are fixed to the foundation 4 and extend in the vertical direction. The attachment of the water-side column 10 and the water-side column 12 and the foundation 4 will be described in detail with reference to FIGS.

  The horizontal rails 22 are long rod-like members that are respectively constructed by three water upper columns 10 and three water columns 12. The vertical rail 20 is installed between the two horizontal rails 22 so as to be inclined with respect to the ground. The solar cell panel 2 is disposed on a lattice formed by the vertical rail 20 and the horizontal rail 22.

  The frontage brace 16 is a member that connects one upper part and the other lower part of the water-side support column 10 or the water-side support column 12 adjacent in the frontage direction. When snow accumulates on the solar cell panel 2, a large force is applied to the support columns 10, 12 and the horizontal rail 22. When an earthquake occurs with snow, a horizontal force is applied to the foundation 4. Further, when a strong wind is blown up, a force is applied to the connecting portion between the horizontal rail 22 and the column. The frontage brace 16 has a role of increasing the structural strength of the solar cell panel mount 1 by dispersing the above-described force over a plurality of supports and foundations.

  The depth brace 14 is a member that connects the upper part of the water-side struts 12 adjacent to the depth direction and the lower part of the water-side struts 10. When the snow on the solar cell panel 2 falls, a large force is applied to the underwater side rail 22 and the underwater column 12. When an earthquake occurs in this state, a horizontal force is applied to the foundation 4. Further, when a strong wind is blown up, a force is applied to the joint portion between the underwater side rail 22 and the underwater column 12. The depth brace 14 has a role of increasing the structural strength of the solar cell panel mount 1 by dispersing the above-mentioned force from the water-side structure to the water-side structure.

  In addition, the number of the foundations 4 and the supports 10 and 12 is appropriately determined depending on the size of the site where the solar cell device 100 is installed, and is not limited to the number shown. Further, the number of the vertical rails 20 and the horizontal rails 22 is determined by the number of the support columns 10 and 12.

  FIG. 3 is an enlarged perspective view of a pair of the water-side support column 10 and the water-side support column 12 adjacent to each other in the depth direction, and FIG. 4 shows the attachment portion between the water-side support column 10 and the foundation 4 in an enlarged manner. FIG.

  The column mounting bracket 30 includes a bottom plate 30a disposed on the upper surface of the foundation 4, and two standing walls 30b that are vertically provided from the bottom plate 30a and extend in parallel to each other.

  The bottom plate 30a is formed with a bolt hole (not shown) through which an anchor bolt 32 embedded in advance on the upper surface of the foundation 4 is inserted. The metal fitting 30 is fixed. A spacer may be sandwiched between the post mounting bracket 30 and the upper surface of the foundation 4.

  The two standing walls 30b are arranged at a slightly wider interval than the thickness of the support column 10. Two bolt holes 30c are formed in each of the standing walls 30b. The bolt holes 30 c are equidistant from a through hole (not shown) formed in the support column 10. Another bolt hole 30d may be formed in the standing wall 30b. This bolt hole 30 d is used to connect the front-end brace 16 to the support bracket 30.

  A brace fixing bracket 34 is fastened to the column mounting bracket 30. The brace fixing bracket 34 is a member for connecting the lower end of the depth brace 14, that is, the underwater side end portion, to the column mounting bracket 30.

  The brace fixing bracket 34 has two opposing walls 34a extending in parallel with each other and a bottom wall 34b connecting them, and has a U-shape as a whole. The distance between the two opposing walls 34 a is slightly wider than the thickness of the depth brace 14. Bolt holes 34d that are equidistant from the bolt holes 30c formed in the standing wall 30b of the column mounting bracket 30 are formed in the bottom wall 34b. Moreover, the bolt hole 34c is vacated also in each opposing wall 34a. The depth brace 14 is fixed to the brace fixing bracket 34 by inserting the hexagon bolt 36 through the through hole 14a and the bolt hole 34c vacated at the lower end of the depth brace 14 and tightening the nut 38.

  As can be seen from FIG. 4, the column mounting bracket 30, the column 10 and the brace fixing bracket 34 are fastened together by a common bolt. More specifically, a long-axis hexagon is formed in the bolt hole 30c formed in the standing wall 30b of the column mounting bracket 30, the through hole of the column 10, and the bolt hole 34d formed in the bottom wall 34b of the brace fixing bracket 34. A bolt 56 is inserted and fastened by a nut 58. By adopting such a joint fastening structure, it is possible to reduce the number of parts required for fastening and simplify the work process.

  In the present embodiment, the depth brace 14 is directly connected to the column mounting bracket 30 via the brace fixing bracket 34. With such a structure, the load from the depth brace 14 is applied to the base of the water-side support column 10, that is, relatively close to the foundation 4. Therefore, the bending moment applied to the water-side strut 10 can be reduced as compared with the case where the depth brace is connected to the middle portion of the water-side strut 10. Therefore, the required bending strength of the support can be suppressed.

  In this embodiment, the upright wall 30b of the column mounting bracket extends in parallel with the front direction of the solar cell panel mount 1, and the opposing wall 34a of the brace fixing bracket 34 extends in parallel with the depth direction of the solar cell panel mount 1. Has been placed. Usually, the bending moment in the front direction of the water-side support column 10 is larger than the bending moment in the depth direction. Therefore, by extending the standing wall 30b of the column mounting bracket 30 in the frontage direction and increasing the bottom area of the bottom plate 30a, the bending moment in the frontage direction can be sufficiently countered. However, depending on the structure of the solar cell panel mount 1, the upright wall 30b of the column mounting bracket may be arranged to extend in the depth direction of the solar cell panel mount.

  Further, the front-end brace 16 can be further fixed to the column mounting bracket 30 by making the extending directions of the standing wall 30b of the column mounting bracket 30 and the opposing wall 34a of the brace fixing bracket 34 perpendicular to each other.

  FIG. 5 is a side view of the water-side support column 10 and the water-side support column 12 of FIG.

  Usually, when the depth brace 14 is attached to the solar cell panel mount 1, it is necessary to position the depth brace 14, so that the underwater end of the depth brace 14 is first temporarily fixed to the brace fixing bracket 34, It is necessary to fasten the brace fixing bracket 34 together with the column mounting bracket 30 and the column 10. Therefore, in this embodiment, as can be seen from FIG. 5, the bolt hole 34c through which the bolt for fixing the depth brace 14 is inserted in the brace fixing bracket 34 is above the bolt hole 34d through which the bolt for joint fastening is inserted. Is arranged. As a result, even after the underwater end of the depth brace 14 is temporarily secured, a space is created below the underwater end, so that the brace fixing bracket 34 is attached to the column mounting bracket 30 using the bolts 56 in that state. It is possible to fasten together with the column 10.

  FIG. 6 is an enlarged perspective view of the upper portion of the underwater support column 12 of FIG.

  An upper column attachment bracket 42 is fixed to the upper part of the water column 12. The upper column mounting bracket 42 is a member that connects the underwater column 12 and the horizontal rail 22. The upper column mounting bracket 42 includes a bottom plate 42a on which the horizontal rail 22 is placed, and two standing walls 42b that are vertically provided from the bottom plate 42a and extend in parallel to each other.

  The bottom plate 42 a is formed with a notch 42 e for passing a bolt for fastening the horizontal rail 22, and the horizontal rail 22 and the water column 12 are connected by tightening the nut 72.

  The two standing walls 42 b are arranged at a slightly wider interval than the thickness of the support column 12. Each standing wall 42 b has a bolt hole equidistant from a through hole (not shown) formed in the column 12, and the column 12 is fastened to the standing wall 42 b using a bolt 76 and a nut 78.

  The two standing walls 42 b are also provided with bolt holes for fastening the upper end of the depth brace 14, that is, the underwater end, and the depth brace 14 is fastened using the bolts 46.

  In this way, by adding a structure for connecting the depth brace 14 to the upper column mounting bracket 42 that fixes the underwater column 12 and the horizontal rail 22, the number of parts required for fastening is reduced and the work process is simplified. Can be realized. Further, since it is not necessary to screw another metal fitting for fixing the depth brace to the column 12, it is not necessary to secure the thickness of the column. Therefore, the weight of the underwater support column 12 can be suppressed.

  Further, by directly connecting the depth brace 14 to the upper column mounting bracket 42, the force received by the depth brace can be distributed not only to the column 12 but also to the horizontal rail 22.

  Further, since the depth brace 14 is connected to the uppermost part of the water-side column 12, the depth brace 14 is added to the water-side column as compared with the case where the depth brace 14 is connected to the middle portion of the water-side column 12. The bending moment can be reduced. Therefore, the required bending strength of the underwater support column can be suppressed.

  As can be seen from FIG. 5, in the upper column mounting bracket 42, the bolt hole 42 d through which the bolt fixing the column is inserted and the bolt hole 42 c through which the bolt connecting the depth brace 14 is inserted are substantially the same in the vertical direction. In position. Thereby, the bending moment which arises in the underwater support | pillar 12 by the load from the depth brace | blade 14 can be minimized.

  As described above, in the solar cell panel mount according to the present embodiment, the depth brace is coupled to the middle portion of the column by coupling the depth brace to the column mounting bracket that fixes the water-side column to the foundation. In comparison, the bending moment of the water column can be suppressed. Also, by connecting the depth brace to the upper strut mounting bracket that connects the underwater strut and the horizontal rail, the bending moment of the underwater strut can be reduced compared to when the depth brace is coupled to the middle part of the strut. Can be small.

  Therefore, the maximum bending strength of the strut can be suppressed, and even in areas where the load on the strut is large and the amount of vertical snow is large, it is not a steel material such as stainless steel that has been used conventionally, but a lower strength aluminum alloy Thus, each member of the solar cell panel mount can be manufactured.

  As described above, since the column mounting bracket 30, the brace fixing bracket 34, and the upper column mounting bracket 42 have relatively simple shapes, they can be manufactured by extrusion molding of an aluminum alloy. Aluminum alloys are excellent in corrosion resistance, and are particularly suitable for solar cell panel mounts installed in snowy areas. Moreover, since it is lighter than stainless steel etc., the labor required for transportation and installation of the solar cell panel mount is reduced. However, as a matter of course, the column mounting bracket 30, the brace fixing bracket 34, and the upper column mounting bracket 42 may be manufactured from other materials using other manufacturing methods such as casting.

  As mentioned above, although this invention was demonstrated based on embodiment, embodiment only shows the principle and application of this invention. In the embodiment, many modifications and arrangements can be made without departing from the spirit of the present invention defined in the claims.
