Summary of the Invention

Problems to be Solved by the Invention

[0004] However, this conventional eaves end upward prevention fitting was provided only within the range where the solar cell module is arranged. On the other hand, the roof material arranged around the roof material type solar cell module may be cut due to dimensional relationships such that the roof material cannot be arranged as it is with the solar cell module. The roof material cut in this way may have weakened fixation to the field board, and there was a concern about wind resistance particularly on the gable side.

[0005] An object of the present invention is to provide a gable-side arrangement member for reliably fixing a roof material adjacent to a roof material type solar cell module in the purlin row direction to a field board together with the gable-side roof material type solar cell module.

Means for Solving the Problems

[0006] The eave-side support member of the present invention is installed between the roof deck and the solar cell module located at the outermost edge of the eaves when a roof material type solar cell module is installed on the roof of a building together with the roofing material, and comprises a module support portion on which the solar cell module is placed, and a roofing material support portion located at an extension of the module support portion in the longitudinal direction at the time of installation, and supporting the roofing material by placing the eave-side end of the roofing material located at the outermost edge of the eaves, which is placed adjacent to the solar cell module.

[0007] In this configuration, the module support section supports the solar cell module, and the roof material support section supports the roof material positioned adjacent to the solar cell module. This ensures that the roof material adjacent to the roof material solar cell module in the longitudinal direction, along with the roof material solar cell module on the eaves side, can be securely fixed to the roof deck.

[0008] Furthermore, the eaves-side support members may be provided with bird-proof walls to seal any gaps that occur during installation and communicate with the roof sheathing in the longitudinal direction.

[0009] This configuration prevents wild birds from entering through gaps, building nests in the space between the roof decking and the roofing material, and preventing the accumulation of droppings in that space.

[0010] Furthermore, the eaves-side mounting member may include a claw portion that fits and holds the eaves-side end of the solar cell module.

[0011] With this configuration, the solar cell module can be easily held in place by the claw portion.

[0012] Furthermore, the dimensions of the eaves-side placement material in the longitudinal direction at the time of installation may be 1 / 2 or more of the longitudinal dimension of the solar cell module.

[0013] With this configuration, it is possible to use multiple eaves-side mounting members and install multiple solar cell modules so that they protrude in the longitudinal direction from the solar cell array, which is a collection of solar cell modules.

[0014] Furthermore, the eaves-side mounting material may include a roofing material cover that is attached to the roofing material positioned adjacent to the solar cell module, and may also be provided with a cover support portion for inserting and securing the roofing material cover.

[0015] With this configuration, the cover support portion supports the roof material cover, thereby ensuring that the roof material cover attached to the roof material adjacent to the roof material solar cell module on the eaves side is securely fixed to the roof decking.

[0016] Based on the above, the present invention provides an eave-side placement member for securely fixing the roof material adjacent to the roof material-type solar cell module in the longitudinal direction to the roof decking, together with the roof material-type solar cell module on the eave side.

Best Mode for Carrying Out the Invention

[0018] Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 9. In addition, the expression of direction in the following description is based on the direction in the arrangement state on the roof R of the building.

[0019] As shown in FIG. 8, when arranging the roof material type solar cell module 3 together with the roof material 2 on the roof R of the building, the eaves side arrangement member 1 is installed between the solar cell module 3 located at the outermost eaves side and the field board 4. Further, as shown in FIGS. 1 and 2, the eaves side arrangement member 1 includes a module support portion 10 on which the solar cell module 3 is placed, and a roof material support portion 11 that is located at an extended position of the module support portion 10 in the girder row direction (horizontal direction in FIGS. 1 and 2) during installation and supports the roof material 2 by placing the eaves side end portion 20 of the roof material 2 that is located at the outermost eaves side and is arranged adjacent to the solar cell module 3.

[0020] In addition, the “roof material type” in this specification does not refer to being arranged on the roof material 2 (covering the roof material 2), but refers to an arrangement form that is directly arranged on the field board 4 (including the intervention of a waterproof sheet, etc.). Further, the roof material type solar cell module 3 refers to all solar cell modules that can be mixed and tiled with the roof material 2. Furthermore, the roof R to which this embodiment is applied is an inclined roof that extends from the eaves (lower) side to the ridge (upper) side.

[0021] In this eaves side arrangement member 1, the module support portion 10 supports the solar cell module 3, and the roof material support portion 11 supports the roof material 2 arranged adjacent to the solar cell module 3. Thereby, the eaves side arrangement member 1 can reliably fix the roof material 2 adjacent to the outermost eaves side roof material type solar cell module 3 in the girder row direction to the field board 4 together with the outermost eaves side roof material type solar cell module 3.

[0022] The roof material 2 is, for example, a tile (see FIG. 8). In addition, in this embodiment, a roof material cover 5 attached to the roof material 2 arranged adjacent to the solar cell module 3 is used.

[0023] The solar cell module 3 is plate-shaped and, for example, is positioned with its power-generating surface facing the sun. Furthermore, the solar cell module 3 has a different shape from the roofing material 2, and its shape when viewed directly from the roof is rectangular. In this embodiment, the solar cell module 3 is positioned with its longitudinal direction aligned with the girder direction.

[0024] The roofing material cover 5 comprises an upper cover surface 50 facing upward when attached to the roofing material 2, a side surface of the cover facing the side surface in the direction intersecting the direction toward the eaves and ridge (beam direction) of the solar cell module 3 (girder direction), and a chamfered lateral portion located between the upper cover surface and the side surface of the cover. The roofing material cover 5 also has an eave-side side surface facing the eaves and an eave-side chamfered portion located between the upper cover surface and the eave-side side surface. Furthermore, the roofing material cover 5 has an extension portion that extends from the edge of the eave-side side surface on the roof decking 4 side toward the ridge along the roof decking 4. The extension portion of the roofing material cover 5 is the part that is inserted into the eave-side mounting material 1.

[0025] In this embodiment, for example, if the dimension of the solar cell module 3 in the beam direction is not a multiple of the dimension of the roofing material 2 in the same direction, the roofing material 2 adjacent to the solar cell module 3 is cut before the roofing material 2 is placed. For example, if the dimension of the solar cell module 3 in the same direction is 546 mm, the dimension of the roofing material 2 in the same direction is set to 273 mm.

[0026] Furthermore, in this embodiment, the roof material cover 5 covers the exposed cut surface of the roof material 2. This prevents damage to the appearance of the roof R to which the roof material 2 and solar cell modules 3 are attached, even without painting the cut surface of the roof material 2.

[0027] The eaves-side support member 1 is made of sheet metal such as steel plate, as shown in Figures 1 to 7. The outer surface of the eaves-side support member 1 is painted or plated as necessary. The eaves-side support member 1 may also be made of other materials such as molded resin, as long as it has sufficient strength to support the weight of the solar cell module 3 located at the eaves and the roofing material 2 placed adjacent to this solar cell module 3.

[0028] The eaves support member 1 of this embodiment comprises a main body 12 including a module support portion 10 and a roof material support portion 11. In addition to the main body 12, the eaves support member 1 also comprises a bent rising portion 13.

[0029] The main body 12 includes a module-compatible portion 120 that is covered by the solar cell module 3 (see Figure 1). The main body 12 also includes an overhang portion 121 that extends beyond the solar cell array formed by the assembly of the solar cell modules 3.

[0030] The module-compatible portion 120 is, for example, a flat plate. The module-compatible portion 120 is in surface contact with the roof sheathing 4. The module-compatible portion 120 extends along the roof sheathing 4 from the ridge side to the eaves side. In this embodiment, the module-compatible portion 120 is a substantially rectangular plate and is arranged with its longitudinal direction aligned with the girder direction.

[0031] The overhang portion 121 is, for example, flat. The overhang portion 121 is in surface contact with the roof sheathing 4. The overhang portion 121 is continuous with the module-compatible portion 120 in the longitudinal direction. In this embodiment, the overhang portion 121 is a substantially rectangular plate and is arranged with its longitudinal direction aligned with the longitudinal direction.

[0032] Furthermore, the main body 12 includes a first main body rising portion 122 that is bent at the eaves-side end of the module-compatible portion 120. The solar cell module 3 is placed on the first main body rising portion 122 (in this embodiment, the top surface of the first main body rising portion 122). In this embodiment, the module support portion 10 also serves as the first main body rising portion 122.

[0033] Furthermore, the main body 12 includes a second main body rising portion 123 that is bent at the eaves-side end of the protruding portion 121.

[0034] The rising portion 13 is, for example, a portion that extends from the eaves-side edge of the module-compatible portion 120. In this embodiment, the rising portion 13 is formed separately from the module-compatible portion 120 and is attached to the eaves-side end of the module-compatible portion 120 by screwing or fitting. Alternatively, the rising portion 13 may be integrally formed with the eaves-side end of the module-compatible portion 120 by welding.

[0035] Furthermore, the rising portion 13 includes a flat portion 130 on which the eave-side end portion 20 of the roofing material 2 located at the furthest eaves side rests, and a protruding portion 131 formed by bending at the eave-side edge of the flat portion 130 (see Figures 1, 3, and 7). In addition, the roofing material support portion 11 includes a connecting portion 132 that connects the eave-side edge of the module-compatible portion 120 to the flat portion 130.

[0036] The flat portion 130 is a plate-shaped part on which the roofing material 2 is placed. The flat portion 130 also extends along the roof decking 4. In this embodiment, the flat portion 130 is the roofing material support portion 11.

[0037] The protruding portion 131 has a shape that rises upward over the entire length of the eave-side end of the flat portion 130 in the longitudinal direction. In this embodiment, the protruding portion 131 is covered from the eave side by the eave-side end of the roofing material cover 5. This configuration prevents a decrease in wind resistance around the protruding portion 131 compared to a configuration in which the protruding portion 131 is only attached to the roofing material 2.

[0038] Furthermore, the protruding portion 131 abuts against the eaves-side end surface of the roofing material 2. In this eaves-side placement material 1, the protruding portion 131 acts as a non-slip surface for the roofing material 2 when it is temporarily placed on the protruding portion 131 during construction. In addition, the protruding portion 131 can be used as a guide for positioning when laying out the roofing materials 2.

[0039] The eaves-side support member 1 is provided with a bird-proof wall 14 that closes the gap that occurs during installation and communicates with the roof sheathing 4 in the longitudinal direction (see Figures 5 and 6). Therefore, the eaves-side support member 1 prevents wild birds from entering through the gap and building nests in the space between the roof sheathing 4 and the roofing material 2, or from accumulating droppings in that space.

[0040] The bird-proof wall 14 is integrally formed with the longitudinal end of the overhang portion 121. The bird-proof wall 14 is, for example, plate-shaped. Furthermore, the bird-proof wall 14 covers the gap that occurs between the flat portion 130 of the rising portion 13 and the member (not shown) that supports the roofing material 2 at the longitudinal end of the overhang portion 121. Although the bird-proof wall 14 is integrally formed with the overhang portion 121, it may also be formed separately from the overhang portion 121 and attached to the overhang portion 121.

[0041] The eaves-side mounting member 1 is equipped with claw portions 15 that fit and hold the eaves-side end portion 30 of the solar cell module 3 (see Figure 1). Therefore, the eaves-side mounting member 1 can easily hold the solar cell module 3 with the claw portions 15. In this embodiment, the claw portions 15 are positioned at an intermediate position in the longitudinal direction of the module-compatible portion 120. In addition, two claw portions 15 are provided spaced apart from each other.

[0042] The claw portion 15 extends from the eaves side to the ridge side along the module-compatible portion 120. In this embodiment, the claw portion 15 includes a first claw portion 151 and a second claw portion 152 that are stacked in the thickness direction to ensure strength, enabling firm fixation against upward loads applied to the solar cell module 3.

[0043] The second claw portion 152 is located closer to the roof sheathing 4 than the first claw portion 151. The first claw portion 151 is continuous with the eaves end of the module-compatible portion 120. Although the first claw portion 151 is integrally formed with the module-compatible portion 120, it may also be formed separately from the module-compatible portion 120 and attached to the module-compatible portion 120.

[0044] The second claw portion 152 may be formed separately from the module-compatible portion 120 and attached to the module-compatible portion 120. In this embodiment, the second claw portion 152 extends from the base portion 153 superimposed on the module-compatible portion 120. The second claw portion 152 is integrally formed with the base portion 153, but it may also be formed separately from the base portion 153 and attached to the base portion 153.

[0045] Furthermore, as shown in Figure 9, the eaves-side mounting member 1 includes a cover support portion 16 into which the roof material cover 5 (in this embodiment, the extended portion of the roof material cover 5) is inserted and secured. With this eaves-side mounting member 1, the cover support portion 16 supports the roof material cover 5, so that the roof material cover 5 attached to the roof material 2 positioned adjacent to the roof material type solar cell module 3 at the eaves side can be securely fixed to the roof deck 4 together with the roof material type solar cell module 3 at the eaves side. In this embodiment, the cover support portion 16 is located between the flat portion 130 of the rising portion 13 and the main body 12.

[0046] Furthermore, the eaves-side support member 1 has a longitudinal dimension at the time of installation that is at least half of the longitudinal dimension of the solar cell module 3 (in this embodiment, the longitudinal dimension of the solar cell module 3). Therefore, it is possible to use multiple eaves-side support members 1 and install them so that they protrude in the longitudinal direction from the solar cell array, which is a collection of multiple solar cell modules 3. Also, when the eaves-side support member 1 protrudes in the longitudinal direction from the solar cell array, this protruding portion is the overhang portion 121.

[0047] At least one eaves-side support member 1 is placed for each solar cell array. In addition, the roof material support portion 11 is located on the portion of the eaves-side support member 1 that protrudes outward from the solar cell array.

[0048] In this embodiment, multiple eaves-side support members 1 are arranged around a single solar cell array. The lengths of each eaves-side support member 1 arranged around a single solar cell array may be the same or different. By appropriately combining eaves-side support members 1 with different lengths in the longitudinal direction and arranging them around the solar cell array, the eaves-side support members 1 can be positioned around the solar cell array in a desired overhang state.

[0049] It should be noted that the eaves-side arrangement material of the present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the invention. For example, the configuration of one embodiment can be added to the configuration of another embodiment, and a part of the configuration of one embodiment can be replaced with the configuration of another embodiment. Furthermore, a part of the configuration of one embodiment can be deleted.

[0050] In the above embodiment, the eaves-side placement member 1 was positioned on the right side when viewing the solar cell array from the eaves side towards the ridge side, as shown in Figure 8. However, in order to position it on the left side of the solar cell array, it is possible to form an eaves-side placement member 1 that is symmetrical to that of the above embodiment.

[0051] For example, the eaves support member 1 only needs to include at least a module support part 10 and a roof material support part 11, and does not need to include at least one of the bird-proof wall 14, claw part 15, and cover support part 16.

[0052] In the above embodiment, the eaves-side support member 1 had a protruding portion 131 on the rising portion 13, but it does not have to have a protruding portion 131. That is, the eaves-side support member 1 only needs to have at least a flat portion 130. [Explanation of Symbols]
