  The solar power generation sheet mounting structure according to the present invention will be described in each embodiment.

[First embodiment]
The solar power generation sheet mounting structure according to the first embodiment of the present invention will be described in detail with reference to FIGS. 1 to 4, an arrow UP indicates an upward direction, an arrow C indicates a beam direction, and an arrow W indicates a girder direction.

  In this embodiment, a solar power generation sheet mounting structure for mounting a solar power generation sheet on a light roof with a relatively simple configuration used in buildings such as public facilities, factories, warehouses, and barns will be described. Examples of the photovoltaic power generation sheet include a thin film photovoltaic power generation sheet made of amorphous silicon, a microcrystalline tandem type, and the like.

  As shown in FIG. 1, the roof purlin 51 is arranged in the girder direction. A plurality of main houses 51 are arranged at predetermined intervals from the ridge to the eaves. The main building 51 is provided with a plurality of slate corrugated plates 52 (roof slate). As shown in FIG. 3A, the plurality of slate corrugated plates 52 are arranged such that end portions 52a and 52b of adjacent slate corrugated plates 52 overlap in the vertical direction. As shown in FIGS. 3 and 4, the plurality of slate corrugated plates 52 are fixed by hook bolts 53 by a packing 54, a washer 55, and a nut 56. Specifically, the slate corrugated plate 52, the packing 54, and the washer 55 are sequentially inserted into the upper end portion 53b side of the hook bolt 53, and the nut 56 is screwed into the screw portion provided on the upper end portion 53b side of the hook bolt 53. By combining, the lower end portion 53 a of the hook bolt 53 engages with one end portion 51 a of the purlin 51, and the slate corrugated plate 52 is fixed to the purlin 51. By interposing the packing 54, intrusion of rainwater or the like into the back side of the slate corrugated plate 52 is prevented. Note that the upper end portion 53 b of the hook bolt 53 protrudes upward from the slate corrugated plate 52.

  As shown in FIG. 2A, the solar power generation sheet 1 described above is fixed to the fixing member 10 by an adhesive means. The fixing member 10 has concave portions 11 and 12 provided at least at both end portions 10a and 10b, and flat portions 14 and 15 to which the photovoltaic power generation sheet 1 is fixed. The recesses 11 and 12 are formed in a shape that can overlap when one end 10 a of the fixing member 10 and the other end 10 b of the fixing member 10 are overlapped. Thereby, when constructing the plurality of fixing members 10 on the roof, the plurality of fixing members 10 can be positioned only by overlapping the concave portions 11 and 12 of the adjacent fixing members 10, and positioning work becomes unnecessary. As a result, workability is improved. Examples of the fixing member 10 include a glass fiber reinforced plastic plate, and those having a thickness of 1.0 mm to 2.0 mm are used. Thereby, the fixing member 10 itself is lightweight, and can be constructed on a lightweight roof with a relatively simple configuration of a building such as a public facility, a factory, a warehouse, or a barn, and can be placed on the fixing member 10. Utilization of the photovoltaic sheet 1 can be promoted.

  It is also possible to further provide a recess 13 in the central portion of the fixing member 10. Further, as shown in FIG. 2B, three recesses 23, 24, 25 are provided between both end portions 20a, 20b of the fixing member 20, and flat portions 26, 27, 28 are provided between adjacent recesses. , 29 can be provided. Thus, by providing a recessed part between not only both ends but the plate-shaped thing, the intensity | strength of the fixing members 10 and 20 improves, and the handleability at the time of construction improves. Harnesses (not shown) connected to the terminals of the photovoltaic power generation sheet 1 can be accommodated in the recesses 13, 23, 24, 25 of the fixing members 10, 20. As the bonding means, an elastic adhesive material such as a modified silicone resin is preferable.

  The fixing members 10 and 20 described above are fixed to the support member 61 by fixing means. As shown in FIG. 3, the support member 61 has a shape that extends in the girder direction and is provided with a recessed portion at the center portion and flat portions on both sides thereof in a cross section orthogonal to the longitudinal direction. .

  Specifically, the support member 61 includes a horizontal plate portion 61a, a first vertical plate portion 61b, a second vertical plate portion 61c, a first support plate portion 61d, a second support plate portion 61e, and a third vertical plate portion 61f. And a fourth vertical plate portion 61g. The first vertical plate portion 61b is formed upright from one side end portion of the horizontal plate portion 61a. The second vertical plate portion 61c is erected from the other side end portion of the horizontal plate portion 61a. The first vertical plate portion 61b and the second vertical plate portion 61c are arranged to face each other. The first support plate portion 61d is formed to be connected to the upper end portion of the first vertical plate portion 61b. The second support plate portion 61e is formed to be connected to the upper end portion of the second vertical plate portion 61c. The third vertical plate portion 61f is formed to hang from one side end portion of the first support plate portion 61d. The fourth vertical plate portion 61g is formed to hang from one side end portion of the second support plate portion 61e.

  The first vertical plate portion 61b, the second vertical plate portion 61c, the third vertical plate portion 61f, and the fourth vertical plate portion 61g are formed at substantially the same height. Thereby, the first support plate portion 61d and the second support plate portion 61e become flat, and the fixing members 10 and 20 can be mounted on the first support plate portion 61d and the second support plate portion 61e. Further, the support member 61 can be easily attached to the attachment fitting 30 by placing the support member 61 on the mounting portion 32 of the attachment fitting 30 described later and inserting a fixture 62 such as a self-drill screw into the horizontal plate portion 61a. As described above, since the support member 61 has a concave shape, the head of the fixture 62 is prevented from protruding upward from the first and second support plate portions 61d and 61e. Examples of the support member 61 include those made of high corrosion-resistant hot-dip galvanized steel sheets, and those having a thickness of 0.4 mm to 1.2 mm are used (in the present embodiment, a thickness of 0.6 mm is used).

  As a fixing means for fixing the fixing member 20 to the support member 61, as shown in FIG. 2 (c), there is a tapping screw 71 with a washer. The concave portion 22 of one end portion 20b of the fixing member 20 and the concave portion 21 of the other end portion 20a of the fixing member 20 are overlapped in the vertical direction, and the two adjacent fixing members 20 and 20 are supported by a tapping screw 71 with a washer. It can be fixed to the member 61. Thereby, the fixing member 20 can be supported more reliably, and workability is improved.

  Furthermore, examples of the fixing means for fixing the fixing member 20 to the support member 61 include a washer-attached tapping screw 71 and a holding plate 73 as shown in FIG. The concave portion 22 of one end portion 20b of the fixing member 20 and the concave portion 21 of the other end portion 20a of the fixing member 20 are overlapped in the vertical direction, and a restraining plate 73 is overlapped above them to provide a washer-attached tapping screw 71. The two adjacent fixing members 20, 20 can be fixed to the support member 61. Thereby, the fixing member 20 can be more reliably fixed to the support member 61. Examples of the pressing plate 73 include a shape that covers the end portions 1 b and 1 a of the photovoltaic power generation sheet 1 that is fixed to the fixing member 20 along the concave portion 22 (21) of the fixing member 20. With such a shape, the photovoltaic power generation sheet 1 can also be fixed to the fixing member 20, and weather resistance and wind resistance are improved. The restraining plate 73 may be non-translucent to block light by being colored black or the like. Thereby, deterioration of the adhesive which adheres the photovoltaic power generation sheet 1 to the fixing member 20 can be prevented. Examples of the restraining plate 73 include those made of glass fiber reinforced plastic and high corrosion-resistant hot-dip galvanized steel plate. In the case of a glass fiber reinforced plastic, one having a thickness of 1.0 mm to 2.0 mm is used. When it is made of a highly corrosion-resistant hot-dip galvanized steel sheet, one having a thickness of 0.3 mm to 0.8 mm is used. Such a fixing means can also be applied to the fixing member 10.

  The support member 61 is fixed to a plurality of mounting brackets (mounting tools) 30 by a fixing tool 62. The mounting bracket 30 is fixed to each hook bolt 53 described above. That is, one mounting bracket 30 is fixed to one hook bolt 53. Specifically, the mounting bracket 30 is inserted into the upper end portion 53 b of the hook bolt 53, and the mounting bracket 30 is fixed to a predetermined height by the nut 34.

  As shown in FIGS. 3 to 5, the mounting bracket 30 includes a mounting portion 31, a mounting portion 32, and a vertical plate portion 33. The attachment part 31 is plate-shaped, and is formed to be curved in the width direction so that the center part protrudes upward. A bolt hole 31 a into which the upper end portion 53 b of the hook bolt 53 can be inserted is provided at a substantially central portion of the attachment portion 31. The mounting portion 32 has a shape longer than the width of the support member 61 and is formed in a plate shape. Thereby, even if the distance between the hook bolts 53 adjacent to each other in the girder direction is deviated, the mounting can be accurately performed only by placing the support member 61 on the mounting portion 32 of the mounting bracket 30 and fixing it with the fixture 62. . The vertical plate portion 33 is connected to one end portion of the attachment portion 31 and one end portion of the mounting portion 32, and is erected from one end portion of the attachment portion 31. The mounting portion 31 and the mounting portion 32 are disposed so as to be offset in the longitudinal direction of the mounting bracket 30. Examples of the mounting bracket 30 include stainless steel and steel plate, and those having a thickness of 1.0 mm to 2.0 mm are used. The mounting bracket 30 having such a shape is general-purpose and can suppress an increase in construction cost. In addition, the height of the mounting bracket 30 can be adjusted by preparing mounting brackets having different vertical plate sizes as needed and mounting them on the hook bolts 53 according to the number of slate corrugated plates 52 overlapped. . Thereby, the height of the some attachment metal fitting 30 can be arrange | equalized.

Here, a method for constructing the above-described solar power generation sheet mounting structure will be described. A plurality of slate corrugated plates 52 are previously attached to the roof with a plurality of hook bolts 53.
First, the photovoltaic power generation sheet 1 is fixed to the fixing member 20 by an adhesive means.

  Subsequently, the mounting bracket 30 is inserted into the upper end portion 53 b side of the hook bolt 53, and these are fixed by the nut 34. Such an operation is performed for each hook bolt 53.

  Subsequently, after attaching the mounting bracket 30 to each of the hook bolts 53 arranged in the digit direction, the support member 61 is mounted on the mounting portion 32 of the mounting bracket 30, and the support member 61 is mounted on the mounting bracket 30 by the fixture 62. It fixes to the part 32.

Subsequently, the fixing member 20 to which the photovoltaic power generation sheet 1 is fixed is disposed on the support member 61 and fixed with a washer-attached tapping screw 71 and, if necessary, a holding plate 73.
By performing these operations over the range in which the solar power generation sheet is applied, the solar power generation sheet is applied to the roof.

  Therefore, according to the photovoltaic power sheet mounting structure according to the present embodiment, the support member 61 is not directly attached to the plurality of hook bolts 53, but the support member 61 is attached to the attachment bracket 30 attached to each of the plurality of hook bolts 53. By fixing 61, the installation of the support member 61 is not restricted by the hook bolt 53, and when the installation location of the hook bolt varies, or the portion of the hook bolt protruding from the slate corrugated plate is upright. Even if there is variation in the position of the upper end (head) of the hook bolt, the support member 61 can be easily attached to the roof at an accurate interval. In addition, since the recesses 21 and 22 are provided at both end portions 20a and 20b of the fixing member 20, the plurality of fixing members 20 can be positioned only by overlapping the recesses 21 and 22 of the adjacent fixing members 20. Thereby, the assembly | attachment property of the some fixing member 20 is securable. Therefore, the photovoltaic power generation sheet 1 can be applied to the roof by a relatively simple operation regardless of the variation direction of the plurality of hook bolts 53 provided on the roof.

  Furthermore, the photovoltaic power generation sheet 1, the fixing member 20, the support member 61, and the mounting bracket 30 themselves are lightweight. Accordingly, it is possible to construct a lightweight roof with a relatively simple configuration of a building such as a public facility, factory, warehouse, or barn, and promote the use of the photovoltaic power generation sheet 1 that can be placed on the fixing member 20. be able to.

  In the present embodiment, only the mounting bracket included in the solar power sheet mounting structure according to the first embodiment described above is changed. The same members as those of the solar power sheet mounting structure according to the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  In this embodiment, as shown in FIGS. 6-8, the substantially U-shaped attachment metal fitting 130 is comprised. The mounting bracket 130 includes a mounting portion 131, a mounting portion 132, and a vertical plate portion 133. The attachment part 131 is plate-shaped, and is formed to be curved in the width direction so that the center part protrudes upward. A bolt hole 131 a into which the upper end portion 53 b of the hook bolt 53 can be inserted is provided at a substantially central portion of the attachment portion 131. The mounting portion 132 is longer than the width of the support member 61 and is formed in a plate shape. Thereby, even if the distance between the hook bolts 53 adjacent to each other in the girder direction is shifted, the support member 61 can be disposed on the mounting portion 132 of the mounting bracket 130 and fixed with the fixing tool 62 so that the mounting can be accurately performed. . The vertical plate portion 133 is connected to one end portion of the attachment portion 131 and one end portion of the mounting portion 132, and is erected from one end portion of the attachment portion 131. The attachment portion 131 and the mounting portion 132 are disposed to face each other. Examples of the mounting bracket 130 include stainless steel and steel plate, and those having a thickness of 1.0 mm to 2.0 mm are used. The mounting bracket 130 is fixed to each hook bolt 53. That is, one mounting bracket 130 is fixed to one hook bolt 53.

  In this embodiment, the solar power generation sheet can be applied to the roof by applying the solar power generation sheet according to the first embodiment described above according to the same work procedure as the solar power generation sheet mounting structure.

  Therefore, according to the photovoltaic power sheet mounting structure according to the present embodiment, the same effects as the photovoltaic power sheet mounting structure according to the first embodiment described above are obtained, and the mounting portion 131 and the mounting structure are mounted. By arranging the portion 132 to face each other, a place to be attached to the hook bolt 53 and a place to fix the support member 61 face each other. Therefore, since the force point of the force pulled upward and the fulcrum are on the same line, the rotating force is not applied, and the strength of the solar power generation sheet mounting structure can be obtained. Thereby, weather resistance and wind resistance are improved.

[Third embodiment]
A solar power generation sheet mounting structure according to the third embodiment of the present invention will be specifically described with reference to FIGS. 9 and 10.

  This embodiment further includes a locking tool that is attached to the recessed portion of the fixing member and is locked to the support member in the solar power generation sheet mounting structure according to the first or second embodiment described above. To do.

  As shown in FIGS. 9 and 10, the locking tool (locking means) 40 includes an upper locking member 41 and a lower locking member 42. The upper locking member 41 is a plate-like object that extends in the width direction of the support member 61 (the direction orthogonal to the longitudinal direction of the support member 61), and is provided in the recess 24 in the upper surface portion 20 c of the fixing member 20. The lower locking member 42 is a plate-like object that extends in the width direction of the support member 61 (a direction orthogonal to the longitudinal direction of the support member 61), and is provided in the recess 24 in the lower surface portion 20 d of the fixing member 20. . The upper locking member 41 and the lower locking member 42 are fixed to the fixing member 20 with rivets 47. The lower locking member 42 includes a locking fixing portion 43, a locking vertical plate portion 44, and a locking collar portion 45. The locking and fixing portion 43 is a plate-like object provided with two holes 43 a and 43 b through which the rivets 47 are inserted, and is fixed to the lower surface portion 20 d of the fixing member 20. The locking vertical plate portion 44 is formed by hanging from one end portion of the locking fixing portion 43. The locking collar portion 45 is plate-shaped, extends in a substantially horizontal direction from the lower end portion of the locking vertical plate portion 44, and is locked to the support member 61. A guide portion (guide portion) 46 that is inclined and extends downward is provided at the distal end portion of the locking collar portion 45. Thereby, when performing the installation which attaches the fixing member 20 to the support member 61, since the guide part 46 guides to the position which latches the latching hook part 45 to the support member 61, workability | operativity improves.

  Therefore, according to the photovoltaic power generation sheet mounting structure according to the present embodiment, by further including the locking tool 40, the fixing member 20 can be reliably locked to the support member 61 by the locking tool 40. .

  As shown in FIGS. 11 and 12, the locking tool (locking means) 140 includes an upper locking member 41 and a lower locking member 142. The lower support member 142 is a plate-like object that extends in the width direction of the support member 61 (a direction orthogonal to the longitudinal direction of the support member 61), and is provided in the recessed portion 24 in the lower surface portion 20 d of the fixing member 20. The upper locking member 41 and the lower locking member 142 are fixed to the fixing member 20 by rivets 47. The lower locking member 142 includes a locking fixing portion 143, a locking vertical plate portion 144, and a locking collar portion 145. The locking fixing portion 143 is a plate-like object provided with two holes 143 a and 143 b through which the rivets 47 are inserted, and is fixed to the lower surface portion 20 d of the fixing member 20. The locking vertical plate portion 144 is formed by hanging from one end portion of the locking fixing portion 143. The locking collar portion 145 is a plate-like object that extends from the lower end portion of the locking vertical plate portion 144 and is locked to the support member 61. The locking collar portion 145 is provided with a bent portion 146 that is bent upward and bent. Thereby, even if the horizontal length of the locking hook portion 145 is shorter than the sum of the horizontal plate portion 61a and the second support plate portion 61e in the width direction of the support member 61, the bent portion 146 is supported by the support member 61. It is locked to.

  Therefore, according to the photovoltaic sheet mounting structure according to the present embodiment, the support member 61 is attached to the mounting bracket 30 by including the locking tool 140 having the locking collar portion 145 provided with the bent portion 146. Since the fixing tool 62 to be fixed and the locking collar portion 145 do not interfere with each other, the workability is improved.

[Other Embodiments]
In the above description, the solar power generation sheet mounting structure including the fixing member 10 (20) to which the solar power generation sheet 1 is fixed and the support member 61 has been described. However, a glass fiber reinforced plastic plate is used as a substrate. Further, it is possible to provide a building material with a photovoltaic power generation sheet in which concave portions are provided at at least both ends of the substrate, and a thin-film photovoltaic power generation sheet is stacked on the substrate. Even if it is a building material with a photovoltaic power generation sheet, the construction material with the photovoltaic power generation sheet itself is lightweight, and the glass fiber reinforced plastic plate is used as a substrate, and a thin film is formed thereon, as in the above-described solar power generation sheet mounting structure. Since the solar power generation sheet is stacked, it is easy to handle and can be attached to a roof or the like relatively easily.

  In addition, although demonstrated above using the attachment structure of the solar power generation sheet applied to the slate corrugated sheet utilized for roofs, such as a factory, it is also possible to apply to the roof comprised with a metal plate etc. Even if it is a case where it applies to such a location, there exists an effect similar to the attachment structure of the photovoltaic power generation sheet mentioned above.

  In addition, although the construction method of the attachment structure of the solar power generation sheet using the fixing member 20 to which the solar power generation sheet 1 is fixed was described above, the solar power generation sheet using the fixing member 10 instead of the fixing member 20 It is also possible to apply to the construction method of the mounting structure.

  According to the solar power generation sheet mounting structure of the present invention, the solar power generation sheet can be attached to the roof relatively easily, and therefore a lightweight steel structure roof such as a slate roof such as a public facility, factory, warehouse, or barn It can be used beneficially.
