Description

The present invention relates to a fixture for a panel, such as a solar cell module, and a fixture provided with the fixture.

In recent years, solar cell modules (solar panels) may be installed on various types of roofs. The solar cell module may be installed, for example, on a non-flat metal roof (folded plate roof) having a standing seaming. Therefore, a fixture for a solar cell module configured to grip a convex portion such as a standing seaming has been developed (Patent Document 1 and Patent Document 2).

Patent Document 1 discloses a solar panel mounting structure for fixing a solar panel via a mounting bracket installed on the top of a folded plate roof. The mounting bracket is fixed to the folded plate roof by a pair of mounting extension pieces that sandwich the top of the folded plate roof. A first mounting bracket is fastened and fixed on a pair of mounting extension pieces via bolts and nuts. Further, the second mounting bracket is fastened and fixed to the shank portion protruding upward from the first mounting bracket via a nut. The first mounting bracket and the second mounting bracket sandwich the end of the solar panel.

The mounting brackets described in Patent Document 2 include a fixture fixed to a standing and seaming, a channel material (columnar member) provided on the fixture, a mounting tool and a fixing plate provided on the channel material, and the like. Has. The channel material extends in a direction orthogonal to the direction in which the seaming extends, and is fixed to the seaming via a fixture. The mounting jig and the fixing plate mount and fix the end portion of the solar cell module, and are fixed to the channel material by mounting bolts.

In general, a fixture configured to grip a convex portion such as a seaming can be installed at an arbitrary position in a direction in which the convex portion extends. However, since such a fixture is fixed to the convex portion, it can be installed only at a predetermined position in the direction in which the convex portion extends and intersects with the extending direction. Here, the distance between the convex parts such as the hemming and seaming varies depending on the structure of the roof. Therefore, when a plurality of solar cell modules are installed in close proximity to each other at high density in a direction intersecting the direction in which the convex portion extends, the position of the fixture with respect to the solar cell module in the direction intersecting the direction in which the convex portion extends is determined. It changes in various ways. Therefore, the distance from the fixture to the end of the solar cell module may not be constant, and the solar cell module may not be stably supported.

In the mounting bracket described in Patent Document 2, it is also conceivable to fix the mounting tool and the fixing plate for mounting and fixing the end portion of the solar cell module at an arbitrary position on the channel material (columnar member). In this case, the positions of the mounting tool and the fixing plate with respect to the solar cell module can be set to a fixed position. However, the load applied to the channel material and the fixture under it changes depending on the position of the mounting tool and the fixing plate with respect to the channel material. Depending on how the load is applied, the mounting bracket may not be able to stably support the solar cell module. In particular, Patent Document 2 does not describe a detailed fixing structure of the channel material and the fixture under the channel material, and does not study the stability of the channel material and the mounting tool and the fixing plate on the channel material.

The fixture according to one aspect has a first portion having a base portion for sandwiching a convex portion formed on an installation surface and a first support portion arranged on the base portion and supporting one end of a columnar member for holding a panel in the lateral direction. It has a support member, a second support member arranged on the first support member and having a second support portion that supports the other end of the columnar member in the lateral direction, and a pressing portion that presses the first support member from above. It has a pressing member and at least a first fastening member that fastens the first support member and the second support member to each other, and the pressing member extends downward from the pressing portion and faces one surface of the base portion. The side portion of the pressing member has a portion, and the side portion of the pressing member is configured to be fastened to the base portion by a second fastening member.

According to the above aspect, the panel can be fixed more stably.

Hereinafter, embodiments will be described with reference to the drawings. In the drawings below, the same or similar parts are designated by the same or similar reference numerals. However, it should be noted that the drawings are schematic and the ratio of each dimension may differ from the actual one.

FIG. 1 is a perspective view showing a fixing device for a panel according to the first embodiment and a panel installed on the fixing device. FIG. 2 is a partial plan view of the fixing device as viewed from the 2A direction of FIG. FIG. 3 is a partial perspective view of a columnar member constituting the fixing device. FIG. 4 is a perspective view of a fixture constituting the fixing device. FIG. 5 is an exploded perspective view of the fixture.

In the first embodiment, the fixing device for the panel is installed on the roof 10 having a standing seaming. Specifically, the roof 10 has an installation surface 12 on which the fixing device is placed, and a plurality of convex portions 14 projecting from the installation surface 12 and extending in one direction. In the present embodiment, the convex portion 14 is formed by a standing seaming, but the present invention is not limited to this. The fixing device for a panel of the present invention can be installed on an installation surface having a convex portion 14 having an arbitrary shape.

The fixing device includes a plurality of fixing tools 90 fixed at the position of the convex portion 14 on the installation surface, and a columnar member 120 supported on the fixing tool 90. The columnar member 120 extends along a direction (X direction in the figure) intersecting the direction in which the convex portion 14 extends (Y direction in the figure). The columnar member 120 may be supported by at least two fixtures 90 adjacent to each other in a direction intersecting the direction in which the convex portion 14 extends. A panel 20 such as a solar cell module is supported by a pair of columnar members 120 that are adjacent to each other in the direction in which the protrusions 14 extend.

The plurality of fixtures 90 can be installed at arbitrary positions on the convex portion 14 extending in one direction. Further, in the direction in which the columnar member 120 extends (the X direction in the figure), the position of the columnar member 120 with respect to the fixture 90 is arbitrary. In other words, the columnar member 120 can be installed at an arbitrary position in the X direction. Therefore, the panel 20 can be installed at arbitrary positions in two directions orthogonal to each other, that is, the X direction and the Y direction. This makes it possible to minimize the gap between the plurality of panels 20 when the plurality of panels 20 are installed on the installation surface 12.

The columnar member 120 has a first loading surface 126a and a second loading surface 126b on which two panels 20 adjacent to each other are loaded in the lateral direction (Y direction in the drawing) of the columnar member 120, respectively. The columnar member 120 has a bottom portion 122 in contact with the fixture 90 described later. 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 columnar 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 contact portion 128 contacts the side surfaces of the pair of panels 20 adjacent to each other in the lateral direction of the columnar member 120.

The columnar 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 of the columnar member 120 in the lateral direction. In this embodiment, the ends of the panel 20 are supported by loading surfaces 126a, 126b and flanges 129.

The columnar member 120 may have the same structure except for two columnar members arranged at both ends in the direction in which the convex portion 14 extends. Further, the two columnar members arranged at both ends in the direction in which the convex portion 14 extends may have a structure different from that of the other columnar members 120. For example, the two columnar members arranged at both ends in the direction in which the convex portion 14 extends may have only one loading surface on which one panel 20 is loaded.

The fixture 90 that supports the columnar member 120 has a base 100, a first support member 130, a second support member 140, a pressing member 150, and first fastening members 160a and 160b. The base portion 100 is configured to sandwich the convex portion 14 formed on the installation surface 12.

As a specific example, the base 100 has a pair of bases 102 facing each other. The base portion 102 includes a contact portion 104 that abuts on the installation surface 12, and at least a pair of grip portions 106 that sandwich the convex portion 14 of the installation surface 12. The pair of base portions 102 are fastened to each other by a third fastening member 180. By fastening the pair of base portions 102 to each other by the third fastening member 180, the pair of grip portions 106 can strongly sandwich the convex portion 14 of the installation surface 12. The shapes of the pair of base portions 102 and the grip portions 106 may be appropriately set according to the shape of the convex portions 14.

The base 100 has an upper portion 110 on which the first support member 130 can be mounted on a pair of base portions 102. The base 100 may have a side 112 extending downward from the top 110 so as to cover a portion of the side surface of the base 102. The lower end 114 of the side portion 112 may be configured to support the load from the panel 20 and to be in contact with the convex portion 14 of the installation surface 12.

The side portion 112 of the base portion 100 and the base portion 102 may be fastened to each other by the second fastening members 170a and 170b. Specifically, the second fastening members 170a and 170b may be composed of nuts 170a and bolts 170b. In this case, the side portion 112 and the base portion 102 have a hole portion 118 into which the bolt 170a is inserted.

The first support member 130 is arranged on the base 100. In this embodiment, the first support member 130 is arranged on the upper portion 110 of the base 100. The first support member 130 has a first support portion 132 that supports one end 122a of the columnar member 120 that holds the panel 20 in the lateral direction. As a specific example, the first support portion 132 is configured by folding back the end portion of the first support member 130 upward, and can sandwich one end 122a of the bottom portion 122 of the columnar member 120.

The second support member 140 is arranged on the first support member 130. The second support member 140 has a second support portion 142 that supports the other end 122b of the columnar member 120 in the lateral direction (the end portion opposite to the one end 122a supported by the first support portion 132). More specifically, the other end 122b of the columnar member 120 may be sandwiched between the second support portion 142 and the first support member 130.

The first support member 130 is fastened to the base 100 by the first fastening members 160a and 160b. Preferably, the first fastening members 160a and 160b fasten the first support member 130, the second support member 140 and the base 100 to each other. As a result, the number of members for fastening the members 100, 130, and 140 can be reduced.

As a specific example, the first fastening members 160a and 160b may be composed of nuts 160a and bolts 160b. The first support member 130 and the second support member 140 have holes 134 and 144 into which the bolts 160b are inserted, respectively. Similarly, the base 100 has a first hole 116 in the upper portion 110 into which the bolt 160b is inserted.

In the present embodiment, the second support portion 142 supports the other end 122b of the bottom portion 122 of the columnar member 120 by pressing the other end 122b of the bottom portion 122 of the columnar member 120 against the first support member 130. Preferably, the second support portion 142 is composed of a curved portion formed at an edge portion of the second support member 140. More specifically, this curved portion has an upwardly convex shape, and protrudes downward at the edge of the curved portion (the edge of the second support member 140). As a result, the second support portion 142 abuts linearly with the columnar member 120 along the direction in which the columnar member 120 extends. Therefore, the force for supporting the columnar member 120 can be increased.

The end portion 146 of the second support member 140 opposite to the second support portion 142 protrudes from the first support member 130 and extends downward toward the base portion 100 (see FIG. 2). .. When the second support member 140 is to be rotated while the first fastening members 160a and 160b are attached, the end portion 146 of the second support member 140 comes into contact with at least one of the first support member 130 and the base 100. That is, the second support member 140 cannot rotate significantly around the first fastening members 160a and 160b in a state where the first fastening members 160a and 160b are attached. In other words, the end portion 146 of the second support member 140 constitutes a rotation regulation portion that regulates rotation around the first fastening members 160a and 160b.

The pressing member 150 is fixed to the base 100 and has a pressing portion 152 that presses the first support member 130 from above. A pair of pressing portions 152 are provided apart from each other in a direction (X direction in the figure) intersecting the direction in which the convex portions 14 extend. Since the pressing portion 152 presses the first support member 130 from above, the problem that the first support member 130 partially lifts from the base 100 can be suppressed, and the first support member 130 that supports the columnar member 120 can be stabilized. ..

As a specific example, the pressing member 150 may have a side portion 151 extending downward from the pressing portion 152 and facing one surface of the base portion 100. The side portion 151 of the pressing member 150 may be configured to be fastened to the base portion 100 by the second fastening members 170a and 170b. More specifically, the side portion 151 of the pressing member 150 has a second hole portion 154 into which the bolt 170b constituting the second fastening member is inserted. The pressing member 150 may have a stopper 156 for preventing the rotation of the bolt 170b inserted in the second hole portion 154.

The first support member 130 may have a mounting portion 131 on which the columnar member 120 is mounted, and a pressing surface 136 located below the mounting portion 131 and in contact with the pressing portion 152. A pair of pressing surfaces 136 may be provided with the mounting portion 131 interposed therebetween in the longitudinal direction of the columnar member 120. The pressing portion 152 of the pressing member 150 comes into contact with the pressing surface 136 from above. The thickness of the pressing portion 152 in the vertical direction (Z direction in the drawing) may be equal to or less than the height from the pressing surface 136 of the first support member 130 to the mounting portion 131.

The pressing portion 152 of the pressing member 150 is preferably provided on the side opposite to the first fastening members 160a and 160b with respect to the mounting portion 131 of the first support member 130. More preferably, the pressing portion 152 of the pressing member 150 is configured to press the end portion of the first supporting member 130 farther from the first fastening members 160a and 160b in the lateral direction of the columnar member 120. .. In this case, since both sides of the first support member 130 can be fixed with the mounting portion 131 sandwiched between them, the end portion of the first support member 130 farther from the first fastening member is lifted due to the influence of strong wind or the like. Problems can be suppressed.

The pressing member 150 is preferably configured so as to be slidable in the vertical direction with respect to the base 100. As an example of a specific configuration, the length of the second hole portion 154 of the pressing member 150 in the vertical direction is longer than the diameter of the portion of the second fastening members 170a and 170b inserted into the second hole portion 154.

Since the pressing member 150 can slide and move in the vertical direction, the first support is provided by loosening the first fastening members 160a and 160b while the panel 20 is loaded on the first loading surface 126a of the columnar member 120. A gap S can be formed between the member 130 and the base 100 (see FIG. 6). By inserting a spacer into the gap S between the first support member 130 and the base 100, the heights of the first support member 130, the second support member 140, and the columnar member 120 can be adjusted. This makes it possible to adjust the non-landing of the panel 20.

FIG. 7 shows an example of the spacer 200 installed in the gap S between the first support member 130 and the base 100. The spacer 200 may be substantially flat. A notch 202 having a diameter larger than the diameter of the first fastening members 160a and 160b may be formed on one side of the spacer 200. By aligning the first fastening members 160a and 160b with the cutout portion 202 of the spacer 200, the displacement of the spacer 200 can be prevented.
