FIG. 5 is an exploded perspective view of the fixture for the panel-shaped member according to the first embodiment.

  In the present embodiment, the fixing structure of the panel-shaped member includes the panel-shaped member 10 and the fixing member 100 for the panel-shaped member. The panel-shaped member 10 is installed on the installation surface 300 by the fixture 100. The installation surface 300 has a waveform as shown in FIG. That is, the installation surface 300 has a plurality of convex portions 310 extending along the first direction F1. The plurality of convex portions 310 may be arranged in a second direction F2 intersecting the first direction F1. Examples of such an installation surface 300 include a corrugated folded roof and a slate roof. Such a mounting surface 300 may include a plurality of roofing materials fastened together by roofing material fasteners extending upward from the mounting surface 300.

  The installation surface 300 may be inclined from a horizontal plane. In this case, the direction from the higher side to the lower side along the maximum inclination line on the inclined installation surface 300 is referred to as “flow direction”. The upstream side in the flow direction is referred to as “above the water”. The downstream side in the flow direction is referred to as “underwater”. A direction orthogonal to the flow direction F1 in a plane parallel to the horizontal plane is referred to as a “lateral direction”. In the present embodiment, the above-described first direction F1 is along the flow direction, and the above-described second direction F2 is along the horizontal direction.

  One panel-shaped member 10 may be provided, or a plurality of panel-shaped members may be arranged adjacent to each other. Each panel-like member 10 may include a panel 12 and a frame 14 attached to an edge of the panel. The frame 14 may surround the outer periphery of the panel 12. The panel-shaped member 10 may be, for example, a solar cell module. In this case, the panel 12 may be a photoelectric conversion element for converting light into electricity.

  The fixture 100 may include a base 110, a support member 120, a rotation preventing member 130, and a holding member 140. The base 110 may have at least two legs 112 sandwiching the convex portion 310 extending in the first direction F1 of the installation surface 300 of the waveform. Each of the legs 112 may have a shape that is inclined in a substantially inverted V-shape so as to contact the slopes on both sides with the vertex of the convex portion 310 interposed therebetween. As described above, since the fixing device 100 is fixed to the installation surface 300 by the legs 112, there is a restriction on the position of the fixing device 100 as compared with the case where the roof material fastener originally provided on the installation surface 300 is used. Be relaxed. Therefore, the restriction on the position of the panel-shaped member 10 is further relaxed.

  The base 110 may have an upper surface 114 that supports the support member 120 and a hole 119 through which the fastening member 180 is inserted. The fastening member 180 reaches the installation surface 300 through a hole 119 formed in the base 110 and a hole 129 formed in the support member 120. Thereby, the base 110, the support member 120, and the installation surface 300 are fastened to each other.

  The waterproof member 182 may be provided between at least one, and preferably both, between the base 110 and the installation surface 300 and between the base 110 and the support member 120. Specifically, the waterproof member 182 between the base 110 and the installation surface 300 may be provided so as to surround the fastening member 180 between the pair of legs 112. Further, the waterproof member 182 between the base 110 and the support member 120 may be provided so as to surround the fastening member 180. The surface on which the hole 129 is formed may be provided at a position recessed from the upper surface 114 so that the waterproof member 182 can be installed.

  The support member 120 is provided on the base 110. The support member 120 may extend along the first direction F in which the protrusion 310 extends. However, the length of the support member 120 along the first direction F is shorter than the length of the panel-shaped member 10 along the first direction F1. The support member 120 is preferably fixed to the projection 310 of the mounting surface 300 by at least two bases 110, ie at least two legs 112. Thereby, the support member 120 is stably fixed to the installation surface 300. More preferably, the support member 120 is fixed to the convex portion 310 of the mounting surface 300 by two bases 110, that is, two legs 112. When the support member 120 is short in the first direction F1, the support member 120 can be sufficiently stably held even by the two legs 112.

  The base 110 is configured to separate the support member 120 in the height direction from the convex portion 310 of the installation surface 300 so that the support member 120 does not contact the above-described roof material fastener extending upward from the installation surface 300. It is preferred that Thereby, the fixture 100 can be installed at any position of the convex portion 310 of the installation surface 300 as long as the legs 112 do not interfere with the roof material fastener. For example, the fixture 100 may be installed such that the roofing fastener is located between the two bases 110. Since the base 110 supports the support member 120 so that the support member 120 does not come into contact with the above-mentioned roofing material fastener extending upward from the installation surface 300, the fixing device 100 is formed of the convex portion 310 of the installation surface 300. It can be installed at any position.

  The holding members 140 and 150 may be supported by the support member 120. The holding members 140 and 150 may include holding portions 148 and 158 that hold ends of the panel-shaped member 10 extending in a second direction F2 intersecting the first direction F1. In the present embodiment, the holding member includes a first holding member 140 provided with a holding portion 148 for holding an end of one panel-shaped member 10 of the panel-shaped members adjacent to each other, and a panel-shaped member adjacent to each other. And a second holding member 150 provided with a holding portion 158 for holding an end of the other panel-shaped member 10. The first holding member 140 and the second holding member 150 may be attached to the support member 120 by a fastening member 190 extending in the height direction.

  The holding portion 148 of the first holding member 140 and the holding portion 158 of the second holding member 150 may have a flange that covers the upper surface of the end of the panel-shaped member 10, more specifically, the upper surface of the frame 14.

  It is preferable that the support member 120 is configured to support the holding members 140 and 150 movably in the first direction F1. Specifically, the support member 120 may have a slide structure 124 that slidably holds the head of the fastening member 190. The slide structure 124 may have a pair of protrusions protruding from the plate 121 with the head of the fastening member 190 interposed therebetween in the second direction F2. The protrusion extends in the first direction F1 and forms a rail that guides the fastening member 190. That is, the rail holds the fastening member 190 movably in the first direction F1 while sandwiching the fastening member 190. Thus, the head of the fastening member 190 can move along the first direction F1 in which the pair of protrusions extend. Accordingly, the first holding member 140 and the second holding member 150 can move along with the fastening member 190 in the first direction F1.

  When the first holding member 140 and the second holding member 150 are movable along the first direction F1, the installation position of the panel-shaped member 10 in the first direction F1 can be adjusted. Thereby, even when it is necessary to install the fixing device 100 avoiding the roof material fastener described above, by adjusting the positions of the first holding member 140 and the second holding member 150 in the first direction F1. The panel-shaped member 10 can be installed at a desired position.

  The movable distance of the first holding member 140 and the second holding member 150 in the first direction F1 is larger than the sum of the length of the leg 112 in the first direction and the length of the roofing fastener in the first direction. preferable. Thereby, even if the leg part 112 is arranged avoiding the roof material fastener, the positions of the first holding member 140 and the second holding member 150 in the first direction F1 can be set to arbitrary positions.

  The first holding member 140 may have a first engaging portion 144, and the second holding member 150 may have a second engaging portion 154 that engages with the first engaging portion 144. Preferably, the second holding member 150 is configured to be rotatable around the axis along the second direction F2 with respect to the first holding member 140. In a specific example, the second engagement portion 154 is formed in a substantially cylindrical shape extending along the second direction F2, and the first engagement portion 144 is rotatably fitted with the second engagement portion 154. It is formed in a substantially cylindrical shape. Thus, one end of the panel-shaped member 10 held by the second holding member 150 can be lifted around the second engagement portion 154 as shown in FIG.

  In a specific example, the first holding member 140 may have a substantially Z-shape when viewed from the lateral direction F2. In this case, the top of the Z-shape may constitute the first engagement portion 144. Further, the fastening member 190 may fasten the first holding member 140 and the second holding member 150 to each other at the bottom of the Z-shape. Further, the first engagement portion 144 may be provided on a bottom portion having a Z-shape.

  The rotation preventing member 130 may have a plate portion 131 provided between the holding members 140 and 150 and the support member 120. The rotation preventing member 130 may be fastened to the holding members 140 and 150 by the fastening member 190 described above. The plate portion 131 of the rotation preventing member 130 may have a hole 139 through which the fastening member 190 is inserted.

  In the present embodiment, the rotation preventing member 130 may include a hook 134 that hooks on the frame 14 of the panel-shaped member 10 held by the second holding member 150. The hook portion 134 may protrude upward from the plate portion 131. The hook 134 projects above the frame mounting surface 152 of the second holding member 150 and is configured to engage with the inner wall of the frame 14 (see FIGS. 2 and 3). Thereby, since the panel-shaped member 10 held by the second holding member 150 is hooked on the hook 134, the panel-shaped member 10 can be prevented from coming off.

  The rotation preventing member 130 may have a stopper 132 projecting below the upper end 122 of the support member 120. The stopper 132 may be a portion extending downward or obliquely downward from the plate portion 131. The stoppers 132 are preferably located on both sides of the support member 120 in the second direction F2. That is, the stopper 132 comes into contact with the side surface of the support member 120 when the rotation preventing member 130 attempts to rotate around the fastening member 190. Accordingly, the stopper 132 can prevent the rotation of the rotation preventing member 130 about the fastening member 190.

  Further, the second holding member 150 may be configured to engage with the rotation preventing member 130 in the rotation direction around the fastening member 190. In the first embodiment, the frame mounting surface 152 of the second holding member 150 is located on both sides of the stopper 132 of the rotation preventing member 130 in the lateral direction F2. Accordingly, the stopper 132 has a function of preventing the holding members 140 and 150 from rotating around the fastening member 190 with respect to the support member 120.

  Preferably, the rotation preventing member 130 has an elastic portion 136 that urges the holding portion 158 upward around an axis along the second direction F2. Specifically, the elastic portion 136 urges the second holding member 150 upward with respect to the first holding member 140. The elastic part 136 may be constituted by a leaf spring part formed on a part of the rotation preventing member 130. The elastic portion 136 urges the second holding member 150 upward to rotate the second holding member 150 upward about the second engagement portion 154. Accordingly, in a state where the panel-shaped member 10 is not held by the second holding member 150, the second holding member 150 is inclined obliquely as shown in FIG. Thereby, it becomes easy to insert the panel-shaped member 10 into the second holding member 150.

  The rotation preventing member 130 may have a covering portion 138 that covers both sides of the second engaging portion 154 in the second direction F2. Thereby, the second holding member 150 can be prevented from coming off the first holding member 140.

  In the fixing device 100 described above, at least one holding member 140, 150 is preferably provided per one supporting member 120, and more preferably only one is provided. That is, the holding members 140 and 150 do not extend over the plurality of support members 120 or the plurality of fixtures 100. Moreover, each of the two opposing ends of the panel-shaped member 10 is held by at least two holding members 140 and 150 provided apart from each other. That is, the panel-shaped member 10 is fixed by at least four fixing members 100 separated from each other. This eliminates the need for a long member extending over the entire side of the panel-shaped member 10, thereby reducing the weight of the entire fixture 100. Therefore, the load on the roof can be reduced.

  More preferably, the length of the holding members 140 and 150 in the second direction F2 is shorter than twice the pitch between the adjacent convex portions 310. Accordingly, the holding members 140 and 150 can further reduce the weight of the entire fixture 100 without being positioned above the convex portion 310 adjacent to the convex portion 310 to which the fixture 100 is fixed.

  Next, a method of installing the panel-shaped member 10 using the above-described panel-shaped member fixture 100 will be described below with reference to FIGS. In the installation method of the panel-shaped member 10 according to the present embodiment, the panel-shaped member 10 is installed on the corrugated installation surface 300 having the convex portion 310 extending in the first direction F1.

Next, as shown in FIG. 6, the fixing member 100 is fixed to the convex portion 310 of the installation surface 300 by the fastening member 180. At this time, as described above, the second holding member 150 is inclined upward by the action of the elastic portion 136.

  Next, the end of the panel-shaped member 10 is held by the holding portion 148 of the first holding member 140. Preferably, the panel-shaped member 10 is inserted into the holding portion 148 from above the water (see FIG. 7). Specifically, the holding member 130 is slid to the water surface in the first direction F1 along the slide structure 124 with the panel-shaped member 10 on the water surface of the fixture 100 being disposed on the upper end portion 122 of the support member 120. As a result, the holding portion 148 of the holding member 130 covers the end of the panel-shaped member 10. Next, the end of the panel-shaped member 10 is held by the holding portion 158 of the second holding member 150 (see FIG. 8). At this time, since the second holding member 150 is inclined upward by the action of the elastic portion 136, the worker holds the one end of the panel-shaped member 10, and then attaches the other part of the panel-shaped member 10 to the holding portion 158. The end can be easily held.

  Then, the worker lowers one end of the panel-shaped member 10 held by the holding portion 158, that is, the gripped portion toward the installation surface 300. Accordingly, since the second holding member 150 rotates about the second engagement portion 154 as an axis, the panel-shaped member 10 can be installed on the installation surface 300 as shown in FIG.
