Description

The present invention relates to a side member for being installed on the side of a panel array in which panels such as a plurality of solar cell joules are lined up, a panel array structure provided with the side member, and installation of the side member. Regarding the method.

In recent years, panel arrays such as multiple solar cell modules may be installed in places such as the roof of a building. The area where the panel array can be installed is not always square or rectangular. For example, in the roof of a general house, the area where the panel array can be installed may become narrower or wider from the eaves side to the ridge side. In this case, the number of panels constituting the panel array in the girder direction of the roof decreases from the eaves side to the ridge side. Therefore, the ends on both sides of the panel array in the girder direction have a stepped shape, which is inferior in design. Therefore, it is known that by arranging side members (corner covers and solar cell modules) having a substantially triangular shape at both end portions of the panel array, both sides of the entire panel array are made substantially linear (patented). Document 1).

In Patent Document 1, a substantially triangular solar cell module (hereinafter, simply referred to as a “side member”) arranged on the side of a panel array seems to have two acute-angled portions of a substantially right triangle cut off. Has a shape. A fitting for mounting is fixed to one of the portions corresponding to the acute-angled portion. The side member is fixed to the solar cell module adjacent to the side member by a mounting fitting.

Japanese Patent No. 3692292

In Patent Document 1, one of the cut-off sharp corners of a substantially triangular lateral member has a mounting fitting for attaching the lateral member to the frame of an adjacent solar cell module. It is provided. However, since another corner of the side member at an acute angle that has been cut off is not fixed, the side member is likely to be misaligned with long-term use. Further, since the side member is fixed to the adjacent solar cell module, the load of the side member is applied to the adjacent solar cell module. Therefore, the long-term reliability of the solar cell module remains uncertain.

Therefore, it is desired that at least one of making it difficult for the side member to be displaced and improving the long-term reliability of the panel array on which the side member is installed is desired.

The side member installed on the side of the panel array according to one aspect is a first corner connecting the first corner portion, the second corner portion, the third corner portion, the second corner portion and the third corner portion.

The panel array structure includes a plurality of panels 20, a plurality of side members 200, and a support device for supporting the panel 20 on the installation surface. The panel may be, for example, a solar cell module. The shape of each panel 20 may be substantially square or substantially rectangular in top view.

The installation surface 10 may be, for example, the roof of a building. In this embodiment, the installation surface 10 may be inclined. In the present specification, the direction from the high side to the low side along the maximum slope line on the sloped installation surface is referred to as "flow direction F1". The upstream side of the flow direction F1 may be referred to as "water upper side". The downstream side of the flow direction F1 may be referred to as "underwater side". Further, the direction orthogonal to the flow direction F1 in the plane parallel to the horizontal plane is referred to as "horizontal direction F2".

The plurality of panels 20 may be arranged in an array. In the present embodiment, the panels 20 are arranged in a direction intersecting the lateral direction F2 and the lateral direction F2. Each panel 20 is supported by a support device.

The support device supports a plurality of panels 20. The support device has a plurality of first support members 110 and a plurality of second support members 120. The first support member 110 extends along the flow direction F1 and is fixed to the installation surface 10. The second support member 120 extends along the lateral direction F2 over at least two first support members 110. The second support member 120 is arranged on the first support member 110.

The first support member 110 can be fixed to the installation surface 10 by a fixing metal fitting (not shown) arranged on the installation surface 10 or a fastening member (not shown) such as a bolt. The plurality of first support members 110 may generally be arranged at intervals of the rafters for fixing to the rafters on the roof.

The first support member 110 includes a rail portion 111 extending along the flow direction F1. The rail portion 111 may be formed in an elongated hollow square column with an open upper surface. More specifically, an opening extending along the flow direction F1 may be formed on the upper surface of the rail portion 111. The upper surface 112 of the rail portion 111 is located on both sides of the opening. The upper surface 112 of the rail portion 111, that is, the upper surface of the first support member 110 constitutes a surface on which the second support member 120 is placed.

The first support member 110 may include a first fixing portion 130 and a second fixing portion 140. The first fixing portion 130 and / or the second fixing portion 140 may be configured to be detachable from the rail portion 111, or may be configured to be detachable from the rail portion 111.

One end 124 of the bottom portion 122 of the second support member 120 is sandwiched between the upper surface of the rail portion 111 and the upper portion 132 of the first fixing portion 130. The second fixing portion 140 has a pressing portion 142 that presses another end of the bottom portion 122 of the second support member 120 against the upper surface of the rail portion 111. In this way, the second support member 120 is fixed to the second support member 120 by the first fixing portion 130 and the second fixing portion 140.

The first fixing portion 130 may extend from the upper portion 132 below the upper surface 112 of the rail portion 111, and may extend below the upper surface 112 of the rail portion 111 along the flow direction F1. The second fixing portion 140 extends below the upper surface 112 of the rail portion 111, and is in contact with the first fixing portion 130 below the upper surface 112 of the rail portion 111. The second fixing portion 140 is fixed to the first fixing portion 130 by a fastening member 160 such as a bolt.

Each second support member 120 has a first loading surface 126a and a second loading surface 126b on which two panels 20 adjacent to each other in the flow direction F1 are loaded, respectively. The second support member 120 has a bottom portion 122 in contact with the first support member 110. The first loading surface 126a and the second loading surface 126b may be located above the bottom 122. Specifically, the first loading surface 126a and the second loading surface 126b are supported above the bottom portion 122 by the supporting portions 127a and 127b extending upward from the bottom portion 122, respectively. Further, the second support member 120 may have a side surface contact portion 128 that separates the first loading surface 126a and the second loading surface 126b. The side surface contact portion 128 abuts on the side surface of the pair of panels 20 adjacent to each other in the flow direction F1.

The second support member 120 may have a flange 129. The flange 129 projects from the upper part of the side surface contact portion 128 to both sides in the flow direction F1.

The bottom portion 122 of the second support member 120 straddles the opening of the rail portion 111 and is mounted on the upper surface 112 of the rail portion 111. The bottom portion 122 of the second support member 120 is fixed on the first support member 110 by the first fixing portion 130 and the second fixing portion 140.

The plurality of second support members 120 may have the same structure except for the two support members arranged at both ends in the flow direction F1. The two support members arranged at both ends in the flow direction F1 may have, for example, only one loading surface on which the panel is loaded.

Next, the side member 200 and its surrounding structure will be described in detail. FIG. 4 is a plan view of the side member 200. FIG. 5 is an enlarged view of the region 5R of FIG. FIG. 6 is a schematic view of the side member 200 as seen from the 6A direction of FIG. However, in FIG. 6, the first fixture 130 described later is not shown for convenience. FIG. 7 is a schematic view of the first fixture 130. FIG. 8 is a schematic view of the side member 200 seen from the 8A direction of FIG. FIG. 9 is an enlarged view of the region 9R of FIG. FIG. 10 is a perspective view of the second support member 120 and the second fixture 300.

The position of the panel 20 at the end of the panel array in the lateral direction F2 differs depending on the position in the flow direction F1. As a result, the end portion of the panel array in the lateral direction F2 has a zigzag shape except for the side member 200. The side member 200 is provided on the side of this panel array (see FIG. 1).

The shape of the side member 200 is substantially triangular when viewed from above. More specifically, the side member 200 has a shape in which at least one vertex of the triangle, that is, a portion corresponding to the two vertices in the present embodiment is cut off.

The side member 200 has a flat plate 202 and a frame 204 located on the side side of the flat plate 202. The flat plate 202 has a substantially triangular shape, and more specifically, the flat plate 202 may have a shape in which the portions corresponding to the two vertices of the triangle are cut off. The flat plate 202 is preferably maintained at substantially the same height as the surface of the panel.

The side member 200 has a first corner portion 201a, a second corner portion 201b, and a third corner portion 201c. Further, the side member 200 has a first edge 203a connecting the second corner 201b and the third corner 201c, a second edge 203b connecting the third corner 201c and the first corner 201a, and a first corner. It has a third edge 203c connecting the 201a and the second corner portion 201b. Each corner portion 201a, 201b, 201c is a portion corresponding to the vicinity of the apex of the triangle.

The first edge 203a of the side member 200 is along one side of the panel 20 adjacent to the upstream side of the side member 200. The second edge 203b of the side member 200 is along one side of the panel 20 adjacent to the side member 200 in the lateral direction F2. The first edge 203a and the second edge 203b may be orthogonal to each other. The side member 200 is arranged in a zigzag shape on the side of the panel array formed by the two panels 20 as shown in FIG. The third edge 203c of the side member 200 is located at the outermost edge of the panel array, and both sides of the entire panel array are substantially linear.

The side member 200 includes a first fixture 220. The first fixture 220 may be non-detachably fixed to the first corner portion 201a of the side member 200. The first fixture 220 is configured to be connectable to the second corner portion 201b of the side member 200 adjacent to the side member 200 at the time of use. That is, the side members 200 adjacent to each other are connected to each other at the corners. In other words, one side member 200 is configured to be connectable to a corner of an adjacent side member at the first corner 201a and a corner of another adjacent side member at the second corner 201b. It is configured so that it can be connected to the unit. As described above, since the side member 200 is fixed at the first corner portion 201a and the second corner portion 201b, the position shift of the side member 200 is less likely to occur as compared with the case where the side member 200 is fixed at one corner portion. Further, since the side members 200 are connected to each other, it is not necessary to fix the side members 200 to the panel. Therefore, the long-term reliability of the panel array can be improved.

The first fixture 220 may have a flat surface portion 222 and an upright portion 224 extending upward from the flat surface portion 222. The flat surface portion 222 may extend in a plane substantially parallel to the flat plate 202 of the side member 200. The flat surface portion 222 may be located below the flat plate 202 of the side member 200. As a specific example, the flat surface portion 222 is attached to the lower surface of the back side frame portion 206 provided on the back side of the flat plate 202.

The flat surface portion 222 extends from the lower surface of the back side frame portion 206 to the outside of the flat plate 202. The upright portion 224 may extend upward from one end side of the flat surface portion 222. In the present embodiment, the upright portion 224 is provided only on one end side of the flat surface portion 222, which extends outward from the flat plate 202.

The erection portion 224 faces the second corner portion 201b of the adjacent side member 200 when in use, that is, when placed in the panel array. The upright portion 224 is configured to be able to be fastened to a corner of an adjacent side member at the time of use by a first fastening member 252.

Specifically, the upright portion 224 of the first fixture 220 has a first insertion hole 250 into which the first fastening member 252, such as a screw, is inserted. The second corner portion 201b of the side member 200 has a second insertion hole 207 into which the first fastening member 252 is inserted (see FIG. 8). The second insertion hole 207 may be provided in the back side frame portion 206 below the flat plate 202 of the side member 200. By inserting the first fastening member 252 into both the first insertion hole 250 and the second insertion hole 207, two adjacent side members 200 are fixed to each other.

It is preferable that the second corner portion 201b of the side member 200 is configured to be fixable to a fixture having the same structure as the first fixture 220 of the same side member 200. If a plurality of side members 200 having such a structure are prepared, a plurality of side members 200 having the same structure can be connected to each other at the corners.

Further, as described above, since the flat surface portion 222 of the first fixture 220 is located below the flat plate 202 of the side member 200, the vertical portion 224 is located below the flat plate 202 of the side member 200 and / or the frame 204. It can be configured so that it does not protrude upward.

The side member 200 is preferably fixed to a support device that supports the panel array. Specifically, the side member 200 may have a second fixture 300 for fixing the first corner 201a to a support device that supports the panel array. As a result, the side members 200 connected to each other can be fixed to the support device at the corners 201a and 201b, so that the misalignment of the side members 200 can be further suppressed. Further, since the side member 200 is fixed to the support device instead of the panel 20, the panel 20 is less likely to be loaded, and the deterioration of the long-term reliability of the panel array can be suppressed.

Specifically, the second fixture 300 fixes the first corner portion 201a of the side member 200 to the second support member 120. More specifically, the second fixture 300 is attached to the side portion of the second support member 120 in the lateral direction F2.

The second fixture 300 may have a support portion 304 that supports the first fixture 220 from below, and a wall portion 302 that extends downward from the support portion 304. The support portion 304 supports the flat surface portion 222 of the first fixture 220.

The flat surface portion 222 of the first fixture has a third insertion hole 240 into which a second fastening member 242 such as a screw can be inserted. On the other hand, the wall portion 302 of the second fixture 300 has a fourth insertion hole 305 into which the second fastening member 242 can be inserted. The second fastener 300 is fixed to the first fixture 220 by inserting the second fastening member 242 into both the third insertion hole 240 and the fourth insertion hole 305.

The wall portion 302 of the second fixture 300 reaches below the panel 20 constituting the panel array supported by the support device, and is configured to be able to be fastened to the second fastening member 242 support device below the panel 20. It is preferable that it is. Specifically, the wall portion 302 of the second fixture 300 has a fifth insertion hole 303 into which a third fastening member 310 such as a screw can be inserted. On the other hand, a sixth insertion hole 121 into which the third fastening member 310 can be inserted is provided on the side portion of the second support member 120. By inserting the third fastening member 310 into both the fifth insertion hole 303 and the sixth insertion hole 121, the second fixture 300 is fixed to the second support member 120.

The sixth insertion hole 121 may be provided below the first loading surface 126a and the second loading surface 126b of the second support member 120.

Further, at least one of the first edge side 203a and the second edge side 203b of the side member 200 can be loaded on the first loading surface 126a and / or the second loading surface 126b of the second supporting member 120 that supports the panel array. It is preferable that it is. In the present embodiment, the first edge 203a of the side member 200 is loaded on the second loading surface 126b of the second support member 120. As a result, the side member 200 is not only fixed at the corners 201a and 201b, but is also supported by at least one of the first edge 203a and the second edge 203b, so that the side member 200 is more stably fixed. ..

Hereinafter, a method of installing the side member 200 will be described. 11, 12, and 13 are diagrams for explaining each step in the method of installing the side member. First, the above-mentioned support device and a plurality of panels 20 are installed on the installation surface 10. As described above, the support device may include the first support member 110 and the second support member 120.

When the distance between the sixth insertion hole 121 and the installation surface 10 is narrow, the second fixture 300 for fixing the side member 200 to the second support member 120 is installed before the second support member 120 is installed. It is preferable to attach it to the second support member 120.

Next, as shown in FIG. 11, the side member 200 is inserted next to the panel 20 at the lateral end of the panel array. At this time, the first fixture 220 is loaded on the second fixture 300 attached to the second support member 120 (see also FIG. 12). Further, it is preferable to mount the first edge 203a of the side member 200 on the second loading surface 126b of the second support member 120. For convenience, FIG. 11 does not show the second support member 120.

Next, the first fixing tool 220 and the second fixing tool 300 are fixed to each other by the second fastening member 242 (see FIG. 12). As a result, the first corner portion 201a of the side member 200 is fixed to the second support member 120 by the first fixture 220 and the second fixture 300. Next, the side member 200 adjacent to the side member 200 fixed to the second support member 120 is arranged, the first fixture 220 of the side member 200 and the second corner portion 201b of the adjacent side member 200 are arranged. And are fixed by the first fastening member 252.
