It is the partial side view of the fixing device seen from 2A direction of FIG. It is a fragmentary perspective view of the columnar member which comprises a fixing device. It is a perspective view of the fixture (2nd state) which fixes a columnar member. It is a disassembled perspective view of a fixing tool. It is a perspective view of the fixing tool (1st state) which fixes a columnar member. It is a perspective view which shows an example of the spacer which can be installed in a fixing tool.

  Hereinafter, embodiments will be described with reference to the drawings. In the following drawings, the same or similar parts are denoted by the same or similar reference numerals. However, it should be noted that the drawings are schematic and ratios of dimensions and the like may differ from actual ones.

  FIG. 1 is a perspective view showing a panel fixing device and a panel installed in the fixing device according to the first embodiment. FIG. 2 is a partial side view of the fixing device viewed from the direction 2A 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 (second state). FIG. 5 is an exploded perspective view of the fixture. FIG. 6 is a perspective view of a fixture (first state) for fixing the columnar member.

  In 1st Embodiment, the fixing device for panels is installed in the roof 10 which has a standing ridge. Specifically, the roof 10 includes an installation surface 12 on which the fixing device is placed, and a plurality of convex portions 14 that protrude from the installation surface 12 and extend in one direction. In this embodiment, although the convex part 14 is formed by standing, it is not limited to this. The panel fixing device of the present embodiment can be installed on an installation surface having a convex portion 14 having an arbitrary shape.

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

  The plurality of fixtures 90 can be installed at arbitrary positions on the convex portion 14 extending in one direction. Further, the position of the columnar member 120 with respect to the fixture 90 is arbitrary in the longitudinal direction of the columnar member 120 (X direction in the figure). 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 an arbitrary position in two directions orthogonal to each other, that is, in the X direction and the Y direction.

  The columnar member 120 has a first loading surface 126a and a second loading surface 126b for loading two panels 20 adjacent to each other in the short direction (Y direction in the drawing) of the columnar member 120 (see FIGS. 2 and 3). ). The columnar member 120 has a bottom portion 122 that comes into contact with a fixture 90 described later. The first stacking surface 126 a and the second stacking surface 126 b may be located above the bottom portion 122. Specifically, the first loading surface 126a and the second loading surface 126b are supported above the bottom portion 122 by portions 127a and 127b extending upward from the bottom portion 122, respectively. Further, the columnar member 120 may include a side contact portion 128 that partitions the first stacking surface 126a and the second stacking surface 126b. The side surface abutting portions 128 abut on 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 protrudes from the upper part of the side contact portion 128 to both sides of the columnar member 120 in the short direction. In the present embodiment, the end portion of the panel 20 is supported by the stacking surfaces 126 a and 126 b and the flange 129.

  The columnar member 120 may have the same structure except for two columnar members disposed 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 different structure from the other columnar members 120. For example, the two columnar members arranged at both ends in the extending direction of the convex portion 14 may have only one stacking surface on which one panel 20 is stacked.

  The fixture 90 that fixes the columnar member 120 includes a base 100, a first support member 130, and a second support member 140. The base portion 100 may be configured to sandwich the convex portion 14 formed on the installation surface 12. The base 100 is configured to be capable of stacking a first support member 130 and a second support member 140 described later.

  As a specific example, the base portion 100 includes a pair of base portions 102 that face each other and a pair of grip portions 106 that sandwich the convex portion 14 of the installation surface 12. 4 and 5, one of the pair of gripping portions 106 is not shown because it is disposed at a position where it cannot be visually recognized.

  The base portion 102 may include a leg portion 104 that abuts on the installation surface 12 and an upper portion 108 on which the first support member 130 and the second support member 140 are placed. The leg portion 104 is provided on the bottom of the base portion 102 and supports the base portion 100.

  The pair of gripping portions 106 are fastened to each other by the second fastening member 180. Since the pair of gripping portions 106 are fastened to each other by the second fastening member 180, the pair of gripping portions 106 can firmly sandwich the convex portion 14 of the installation surface 12. Note that the shapes of the pair of base portions 102 and the grip portion 106 may be appropriately set according to the shape of the convex portion 14.

  The first support member 130 is provided on the base 100. In the present embodiment, the first support member 130 is disposed on the upper portion 108 of the base portion 102. The first support member 130 may include a first stacking unit 136 and a sandwiching piece 132. The first stacking portion 136 is configured to support the bottom portion 122 of the columnar member 120 from below.

  The first support member 130 supports the first end portion 122 a in the short direction of the bottom portion 122 of the columnar member 120. Specifically, the sandwiching piece 132 is configured to sandwich the first end 122 a of the bottom 122 of the columnar member 120 stacked on the first stacking unit 136 from above.

  The length of the sandwiching piece 132 in the vertical direction (Z direction) is longer than the length of the sandwiching piece 132 in the longitudinal direction of the columnar member 120 (in this embodiment, the thickness of the sandwiching piece 132, that is, the length in the X direction). Longer is preferred. Thereby, the clamping piece 132 can hold down strongly the force which the 1st end part 122a of the bottom part 122 of the columnar member 120 tends to lift upwards. Such a structure of the sandwiching piece 132 can be formed by, for example, a sheet metal cutting edge in which an end corresponding to the longitudinal direction of the columnar member 120 is cut into a predetermined shape as in the present embodiment. In addition, the structure of the clamping piece 132 can also be formed by bending.

  The second support member 140 is provided on the first support member 130. The second support member 140 includes a support piece 142 that supports the second end 122 b (the end opposite to the first end 122 a supported by the first support member 130) of the bottom 122 of the columnar member 120. . More specifically, the second end portion 122 b of the columnar member 120 is sandwiched between the support piece 142 and the first stacking portion 136 of the first support member 130.

  The second support member 140 is configured to be rotatable between the first state and the second state. Here, in the first state, the first support member 130 supports the first end 122a of the bottom 122 of the columnar member 120, and the support piece 142 of the second support member 140 is the second of the bottom 122 of the columnar member 120. The end 122b is not supported. Specifically, the first state is a state in which the support piece 142 of the second support member 140 is directed in a direction opposite to the columnar member 120 (see FIG. 6).

  In the second state, the first support member 130 supports the first end 122 a of the bottom 122 of the columnar member 120, and the support piece 142 of the second support member 140 is the second end 122 b of the bottom 122 of the columnar member 120. Is in a state of supporting. Specifically, the second state is a state in which the support piece 142 of the second support member 140 is directed toward the columnar member 120 (see FIGS. 2 and 4).

  The second support member 140 may be attached to the first support member 130 by the first fastening member 160. The first fastening member 160 may be a combination of bolts and nuts, for example.

  The second support member 140 may be configured to be rotatable about the first fastening member 160. In the first state, the second support member 140 does not cover the second end 122 b of the bottom 122 of the columnar member 120. Thereby, the columnar member 120 can be attached to and detached from the first support member 130 in the first state. On the other hand, in the second state, the support piece 142 of the second support member 140 presses the second end 122b of the bottom 122 of the columnar member 120 from above. Thereby, the columnar member 120 is firmly pressed by the first support member 130 and the second support member 140.

  As described above, since the columnar member 120 can be fixed by rotating the second support member 140, the fixture can be easily assembled. Moreover, since it is not necessary to remove the 2nd support member 140 from the 1st support member 130 at the time of an assembly, the loss of the components which comprise the fixing tool 90 can also be suppressed.

  The first fastening member 160 that fastens the first support member 130 and the second support member 140 reaches the base 100. That is, the first fastening member 160 fastens the first support member 130, the second support member 140, and the base 100 to each other.

  The first support member 130 may include a rotation restricting portion 138 that restricts the rotation of the second support member 140 in the first state and the second state. As a specific example, the first support member 130 includes a second stacking portion 137 that supports the second support member 140 from below, and a pair of side wall portions 138 that form a groove that receives the second support member 140. The pair of side wall portions 138 may constitute the aforementioned rotation restricting portion. By restricting the rotation of the second support member 140 in the first state and the second state, the displacement of the support piece 142 in the rotation direction can be prevented. In this case, the second support member 140 can be rotated between the first state and the second state by being lifted above the pair of side wall portions 138.

  The height of the pair of side wall portions 138 (the height with respect to the second stacking portion 137) is the third hole portion 144 of the second support member 140 of the first fastening member 160 in the first state and the second state. It is preferable that it is shorter than the length of the part which protrudes upward from. Here, the third hole 144 of the second support member 140 is a through hole into which the first fastening member 160 is inserted. According to this configuration, the second support member 140 is removed from the pair of side wall portions (rotation restricting portions) 138 simply by loosening the first fastening member 160, specifically, the nut constituting the first fastening member 160 without removing it. Can also be lifted upwards. That is, the second support member 140 can rotate without being completely removed from the first support member 130.

  In the present embodiment, the upper portions of the pair of side wall portions 138 are bent in the longitudinal direction of the columnar member 120 and constitute the first stacking portion 136 described above.

  It is preferable that the first support member 130 and the second support member 140 are configured to be slidable in the short direction of the columnar member 120 with respect to the base 100 together. Thereby, in a state where the columnar member 120 is fixed by the first support member 130 and the second support member 140, the position of the columnar member 120 in the lateral direction can be finely adjusted. Therefore, the installation of the panel 20 becomes easy and the position of the panel 20 can be finely adjusted.

  As an example of a specific configuration, in the short direction of the columnar member 120, the length of the first hole 116 formed in the base portion 100 through which the first fastening member 160 passes is the first fastening member 160. It is longer than the diameter of the portion inserted into the hole 116. In the present embodiment, the third fastening member 190 extends in the short direction of the columnar member 120 and penetrates both of the pair of grip portions 106. The third fastening member 190 functions as a rotating shaft of each gripping portion 106. The first fastening member 160 is erected in combination with the third fastening member 190. Specifically, the lower end portion of the first fastening member 160 is disposed on the third fastening member 190. Therefore, the first fastening member 160 can slide along the third fastening member 190. Accordingly, the first support member 130 and the second support member 140 are configured to be slidable in the short direction of the columnar member 120 with respect to the base 100.

  On the other hand, the second support member 140 is preferably configured not to slide with respect to the first support member 130. In the present embodiment, the diameter of the second hole portion 134 formed in the first support member 130 through which the first fastening member 160 passes is substantially the same as the diameter of the first fastening member 160. In addition, the diameter of the third hole 144 formed in the second support member 140 and through which the first fastening member 160 passes is such that the diameter of the third hole 144 is substantially positioned when the first fastening member 160 is inserted. That is, the diameter of the third hole 144 is substantially the same as the diameter of the first fastening member 160. As described above, since the second support member 140 is configured not to be slidable with respect to the first support member 130, in the second state, the holding piece 132 of the first support member 130 and the support of the second support member 140 are supported. The distance between the piece 142 is constant. However, in order to facilitate insertion of the first fastening member 160, the diameters of the second hole portion 134 and the third hole portion 144 are preferably slightly larger than the diameter of the first fastening member 160. For example, the diameters of the second hole portion 134 and the third hole portion 144 may be about 1 mm larger than the diameter of the first fastening member 160.

  In the first state as shown in FIG. 6, the upper portion 146 of the second support member 140 directed toward the columnar member 120 is inclined in a direction away from the columnar member 120 as it goes from the lower side to the upper side. The upper portion 146 may be located closer to the columnar member 120 than the first fastening portion 160 in the first state. Thus, in the first state, the columnar member 120 is placed on the first support member 130 so that the first end 122a of the bottom 122 of the columnar member 120 is sandwiched between the sandwiching piece 132 and the first stacking unit 136. It becomes easy to put.

  For example, when the installation surface 12 is inclined like a roof of a general house, the fixture 90 is such that the holding piece 132 of the first support member 130 is located on the underwater side and the support piece 142 of the second support member 140. It is preferable to arrange so that is located on the water side.

  In addition, the fixture 90 is configured such that a gap can be formed between the base 100 and the first support member 130 by loosening the first fastening member 160. By inserting the plate-like spacer 200 into the gap, the height of the first support member 130, the second support member 140, and the columnar member 120 can be adjusted. Thereby, the uneven adjustment of the panel 20 is attained.

  FIG. 7 shows an example of the spacer 200 that can be installed in the gap between the first support member 130 and the base 100. The spacer 200 may be a substantially flat plate. A cutout 202 having a width larger than the diameter of the first fastening member 160 may be formed on at least one side of the spacer 200. By aligning the first fastening member 160 with the notch 202 of the spacer 200, it is possible to prevent the spacer 200 from being displaced.

  Next, a fixing method for fixing the columnar member will be described. First, the fixture 90 and the columnar member 120 described above are prepared.

  Next, the fixture 90 is attached to the installation surface 12. Specifically, the fixture 90 is placed on the installation surface 12 such that the pair of gripping portions 106 of the base 100 of the fixture 90 sandwich the convex portion 14 on the installation surface 12. Next, the base portion 100 of the fixture 90 is firmly fixed on the installation surface 12 by tightening the pair of gripping portions 106 with the second fastening member 180.

  Next, the first end 122 a of the bottom 122 of the columnar member 120 is supported by the first support member 130 while the columnar member 120 is placed on the first stacking portion 136 of the first support member 130. At this time, the second support member 140 is in the first state, that is, the support piece 142 does not support the columnar member 120 (the state shown in FIG. 6). In other words, the support piece 142 is oriented in the direction opposite to the columnar member 120. Thus, the columnar member 120 can be placed on the first stacking portion 136 of the first support member 130 without the support piece 142 of the second support member 140 interfering with the columnar member 120. At this time, the columnar member 120 may be stacked on a plurality of fixtures 90 arranged in the longitudinal direction of the columnar member 120.

  Next, from the first state where the support piece 142 of the second support member 140 does not support the second end portion 122 b of the bottom portion 122 of the columnar member 120, the support piece 142 of the second support member 140 forms the bottom portion 122 of the columnar member 120. The second support member 140 is rotated to the second state in which the second end 122b is supported. Specifically, with the first fastening member 160 loosened, the second support member 140 is lifted slightly upward, then the second support member 140 is rotated, and the second support member 140 is firmly secured by the first fastening member 160. Conclude with. As a result, as shown in FIG. 2, the support piece 142 of the second support member 140 is positioned on the upper portion of the second end portion 122 b of the bottom portion 122 of the columnar member 120.

  As described above, the columnar member 120 can be fixed by the fixing tool 90. When supporting the panel 20 such as a solar cell module, the end portions of the panel 20 may be stacked on the first stacking surface 126a and the second stacking surface 126b of the columnar member 120. Thereby, the panel 20 can be installed on the installation surface 12.

  As described above, the content of the present invention has been disclosed through the embodiments. However, it should not be understood that the description and drawings constituting a part of this disclosure limit the present invention. From this disclosure, various alternative embodiments, examples and operational techniques will be apparent to those skilled in the art. Therefore, the technical scope of the present invention is defined only by the invention specifying matters according to the scope of claims reasonable from the above description.

  For example, the fixture 90 according to the above-described embodiment is configured such that the base 100 sandwiches the convex portion 14 on the installation surface 12. The structure in which the fixing tool 90 is fixed to the installation surface 12 is not limited to such a mode. For example, the fixture 90 may be directly or indirectly fixed to the installation surface 12 by a fastening member. Moreover, the base 100 may be comprised from the vertical member extended long along the inclination direction of a roof.

  Moreover, in the said embodiment, the fixing tool 90 fixes the columnar member 120 which supports a panel like a solar cell module. Not only this but the fixing tool 90 may fix arbitrary columnar members.
