Description

[Technical Field]

[0001] The present invention relates to a roof structure having solar panels. [Background technology]

[0002] A roof structure for a building having a roof and a plurality of solar panels mounted on the roof has been known. The plurality of solar panels includes a panel body that generates electricity by receiving sunlight, and a connecting member (e.g., an electric wire) that connects adjacent panel bodies. In general, the connecting member is disposed between the panel body and the roof (below the panel body).

[0003] Also, as an arrangement of multiple solar panels, for example, the one described in Patent Document 1 is known. Specifically, the building described in Patent Document 1 has two solar panels (solar cell modules) that are adjacent to each other in the flow direction of the sloped roof and are arranged so that their ends are positioned at different positions in the orthogonal direction perpendicular to the flow direction. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2021-161666 Summary of the Invention [Problem to be solved by the invention]

[0005] When connecting the panel bodies of the two solar panels described in Patent Document 1, it is conceivable to place a connecting member between the two panel bodies and the roof (below the panel bodies).

[0006] However, because the ends of the panel bodies of the two solar panels described in Patent Document 1 are positioned at different positions in the perpendicular direction, the area adjacent to the two solar cell modules in the flow direction is narrower than when the ends are positioned at the same position in the perpendicular direction. This makes it difficult to secure sufficient space to place the connecting members between the two panel bodies and the roof. Therefore, it may be necessary to place the connecting members in an area away from one panel body in the flow direction and away from the other panel body in the perpendicular direction, i.e., in an area outside the two panel bodies on the roof. In this case, the exposed connecting members unsightly the roof structure, and furthermore, the connecting members are prone to deterioration due to exposure to wind, rain, and direct sunlight.

[0007] The present invention has been made in consideration of such problems, and aims to provide a roof structure that has a good appearance and is capable of suppressing deterioration of the connecting members that connect the panel bodies to each other. [Means for solving the problem]

[0008] In order to solve the above problem, a first invention is a roof structure comprising: a roof; a first panel body provided on the roof and generating electricity by receiving sunlight; a second panel body provided on the roof and adjacent to the first panel body in a predetermined first direction and generating electricity by receiving sunlight; and a connecting member connecting the first panel body and the second panel body; wherein the first panel body is shifted relative to the second panel body in a second direction perpendicular to the first direction, and thereby has a protruding portion that protrudes in the second direction away from the second panel body based on a second end of the second panel body in the second direction; the roof has an exposed surface that is exposed upward in the second direction adjacent to the second end in an area closer to the second panel body of the protruding portion in the first direction; the connecting member extends from the first panel body along the exposed surface to the second panel body; and the roof structure further comprises a covering member provided on the roof to cover an exposed portion of the connecting member that is located on the exposed surface.

[0009] In the roof structure according to the first aspect of the present invention, the first panel body is shifted in the second direction relative to the second panel body. Therefore, the area where the first panel body and the second panel body are adjacent in the first direction is narrower than when the second end and the end of the first panel body in the second direction are positioned at the same position. In this situation where the area below both panel bodies is limited, the first panel body and the second panel body can be reliably connected by arranging the connecting member over the exposed surface of the roof.

[0010] Furthermore, a covering member is provided on the roof so as to cover the exposed portion of the connecting member that is disposed on the exposed surface of the connecting member. Therefore, by covering the connecting member, a good aesthetic appearance can be obtained, and by protecting the connecting member from the external environment such as wind, rain, and direct sunlight, deterioration of the connecting member can be suppressed.

[0011] A second invention is preferably such that, in the first invention, the roof structure further includes an attachment member having a fixing portion fixed to the roof, an attachment portion to which the covering member is attached, and a holding portion that holds the connecting member between the covering member attached to the attachment portion and the roof.

[0012] According to the second aspect of the present invention, a holding portion for holding the connecting member is provided. This prevents the connecting member from moving and coming into contact with surrounding objects, which can lead to damage to the connecting member. Furthermore, since the holding portion is provided on the mounting member for attaching the covering member to the roof, the holding portion that prevents damage to the connecting member can also be used as the mounting member.

[0013] A third invention is the second invention, wherein the holding portion has a shape for holding a portion of the connecting member in a state in which the portion of the connecting member is arranged along the second direction.

[0014] According to the third aspect of the present invention, the holding portion can hold the connecting member arranged on the exposed surface in a position facing the second panel body, thereby preventing the connecting member from moving in an unintended direction when one end of the connecting member comes off the second panel body, such as during initial construction or maintenance of the roof structure.

[0015] A fourth invention is any one of the first to third inventions, wherein the roof has a plurality of roofing materials arranged in the first direction so as to form a plurality of joints that are spaced apart in the first direction and extend in the second direction, and the covering member is attached to the roof in a state where only an area defined by a range in the first direction equivalent to the spacing between two of the plurality of joints in a plan view seen in a direction perpendicular to the first direction and the second direction, and a range in the second direction having a dimension equivalent to that of the protruding portion of the first panel body from the second end in the plan view, is exposed.

[0016] According to the fourth aspect of the present invention, only the area in the first direction corresponding to the distance between the two joints in the covering member is exposed in a plan view, so the covering member can be installed while maintaining the regularity of the roofing material. This reduces the sense of incongruity that the covering member gives to the roofing material when installed on the roof, and maintains the aesthetic appearance of the roof structure.

[0017] Furthermore, according to the fourth aspect of the present invention, only a range in the second direction from the second end of the covering member that has a dimension equivalent to that of the protruding portion of the first panel body in a plan view is exposed. Therefore, the covering member is arranged to fill in the step formed between the first panel body and the second panel body, and the covering member can be provided without detracting from the aesthetic appearance of the roof structure.

[0018] A fifth invention is the fourth invention, wherein the end of the first panel body farthest from the second panel body in the first direction is arranged along a distal joint that is arranged away from the covering member at a distance equal to the distance between the two joints from a proximal joint that is closest to the first panel body, the distance being equal to the distance between the two joints, and the first panel body has a first extension portion that extends from the proximal joint toward the second panel body in the first direction, and the covering member preferably covers the first extension portion so that only the area in the first direction that corresponds to the distance between the proximal joint and the distal joint in the first panel body is exposed in the plan view.

[0019] According to the fifth aspect of the present invention, the exposed areas of the first panel body and the covering member in the first direction can be aligned in a plan view, which allows the first panel body as well as the covering member to be installed while maintaining the regularity of the roof material, thereby achieving both the maintenance of the aesthetic appearance of the roof structure and the protection of the connecting member.

[0020] A sixth invention is preferably such that, in the fourth or fifth invention, the end of the second panel body closer to the first panel body is arranged along a proximal joint of the two joints that is closer to the first panel body, the second panel body has a second extension portion that protrudes in the first direction from a joint of the two joints other than the proximal joint in a direction away from the first panel body, and the roof structure further includes a second covering member that covers the second extension portion so that only an area corresponding to the spacing between the two joints is exposed in the plan view.

[0021] According to the sixth aspect of the present invention, the exposed areas of the covering member and the second panel body in the first direction can be aligned in a plan view, which allows the covering member and the second panel body to be installed while maintaining the regularity of the roof material, thereby achieving both the maintenance of the aesthetic appearance of the roof structure and the protection of the connecting member.

[0022] A seventh invention is any one of the fourth to sixth inventions, wherein the plurality of roofing materials include a first roofing material having a first roof edge in the first direction, and a second roofing material having a second roof edge adjacent to the first roofing material in the first direction and overlapping the first roof edge from above, and the covering member preferably has an inserted portion inserted between the first roof edge and the second roof edge, and an exposed portion extending from the inserted portion in a direction away from the second roofing material and having an area corresponding to the spacing between the two joints in the planar view.

[0023] According to the seventh invention, by inserting the inserted portion between the first roof end and the second roof end, the covering member can be attached to the roof with the exposed portion exposed between the two joints.

[0024] An eighth invention is that, in the seventh invention, it is preferable that the exposed portion has an extension portion extending from the inserted portion along the upper surface of the first roof material, and an accommodating chamber forming portion extending from the extension portion in a direction away from the inserted portion and the roof material so that an accommodating chamber for accommodating the connecting member is formed between the inserted portion and the roof material.

[0025] According to the eighth aspect of the present invention, the extension extends from the inserted portion along the upper surface of the first roof material, so that the extension can contact the upper surface of the first roof material when the inserted portion is inserted between the first roof edge and the second roof edge. Therefore, the inserted state of the inserted portion can be stably supported by the extension.

[0026] Furthermore, since the housing chamber forming portion is provided, it is possible to form a housing chamber for accommodating the connecting member by the housing chamber forming portion while realizing stable support of the inserted state of the inserted portion as described above.

[0027] A ninth invention is that, in the eighth invention, the extension portion has a size that is capable of covering the entire upper surface of the first roof material in the first direction, and it is preferable that the boundary line between the extension portion and the storage chamber forming portion is arranged along the joint formed by the end of the first roof material when the extension portion is arranged along the upper surface of the first roof material.

[0028] According to the ninth aspect of the present invention, the extension covers the entire upper surface of the first roofing material, and the boundary between the extension and the storage chamber forming portion is set along the joint. Therefore, the storage chamber for the connecting member can be formed without disrupting the regularity of the multiple roofing materials, i.e., the regularity of the joints. Therefore, the extension can provide stable support in the inserted state and form the storage chamber while maintaining the aesthetic appearance of the roof structure.

[0029] Furthermore, if another roofing material (third roofing material) is provided on the opposite side of the second roofing material from the first roofing material, and the end of the third roofing material is positioned below the end of the first roofing material, the height of the first roofing material relative to this third roofing material can be effectively utilized as part of the storage space for the connecting member.

[0030] In a tenth aspect of the present invention, in the eighth or ninth aspect of the present invention, it is preferable that the storage chamber forming portion extends at an angle from the extension portion so as to move away from the roof material as it moves in a direction away from the inserted portion.

[0031] According to the tenth aspect of the present invention, since the storage chamber forming portion is inclined, the storage chamber can be formed while suppressing deterioration in the aesthetic appearance of the roof structure due to a sudden change in shape of the covering member.

[0032] An eleventh invention is any one of the eighth to tenth inventions, wherein the extension is preferably joined to the first roofing material in a state of tight contact with an upper surface of the first roofing material.

[0033] According to the eleventh aspect of the present invention, since the extension portion is joined to the first roof material, the inserted state of the inserted portion can be more reliably maintained.

[0034] Furthermore, since the extension is joined in close contact with the upper surface of the first roofing material, it is possible to prevent rainwater and the like from entering between the covering member and the first roofing material. [Effects of the Invention]

[0035] According to the present invention, it is possible to provide a good appearance and to suppress deterioration of the connecting members that connect the panel bodies to each other. [Brief explanation of the drawings]

[0037] Hereinafter, a roof structure according to one embodiment of the present invention will be described with reference to the drawings.

[0038] (Roof structure configuration) FIG. 1 is a side view of a building 1 having a roof structure 2 according to this embodiment. FIG. 2 is a plan view of the roof structure 2 according to this embodiment. FIG. 3 is a partial cross-sectional view of the roof structure 2 taken along line III-III in FIG. 2. FIG. 4 is a partially enlarged view of the area around the mounting member 60 in FIG. 3. FIG. 5 is a plan view showing the state in which the solar panel 30 has been removed from the roof structure 2 in FIG. 2. FIG. 6 is an enlarged view of the lower left portion of FIG. 2. FIG. 7 is a partial cross-sectional view of the roof structure 2 taken along line VII-VII in FIG. 1.

[0039] As shown in FIG. 1, a building 1 has a skeleton (reference numeral omitted) including beams 1a (see FIG. 3), and a roof structure 2 supported by the skeleton.

[0040] The roof structure 2 comprises a roof 10, solar panels 30 mounted on the roof 10 and generating electricity by receiving sunlight, connecting members 40 that connect the solar panels 30 together, a covering member 50 mounted on the roof 10 so as to cover an exposed portion 40P of the connecting member 40 described below that is positioned on the exposed surface 10P (see Figure 6) of the roof 10, and an attachment member 60 (see Figure 6) for attaching the solar panels 30 and the covering member 50 to the roof 10.

[0041] As shown in Figure 2, roof 10 is formed in a rectangular shape in a plan view. Roof 10 is a so-called hip roof, and has opposing trapezoidal roof surfaces 10a and 10b, and opposing triangular roof surfaces 10c and 10d provided between the trapezoidal legs.

[0042] In the following description, the slope direction of the roof surface 10a is referred to as the first direction D1, and the horizontal direction extending along the eaves of the roof surface 10a is referred to as the second direction D2. Furthermore, the direction perpendicular to both the first direction D1 and the second direction D2 is referred to as the third direction D3. Of the first direction D1, the upward direction (ridge direction) is referred to as the +D1 direction, and the downward direction (eaves direction) is referred to as the -D1 direction. Furthermore, of the second direction D2, the right direction in Figure 1 is referred to as the +D2 direction, and the left direction is referred to as the -D2 direction. Of the third direction D3, the downward direction in Figure 3 is referred to as the +D3 direction, and the upward direction is referred to as the -D3 direction.

[0043] Roof surface 10a and roof surface 10b are adjacent to each other to form ridge 10e at the top of roof 10. Roof surface 10a and roof surfaces 10c and 10d are adjacent to each other, respectively, to form corner ridges 10f and 10g that extend downward from the end of ridge 10e in the second direction D2, and roof surface 10b and roof surfaces 10c and 10d are adjacent to each other, respectively, to form corner ridges 10h and 10i that extend downward from the end of ridge 10e in the second direction D2. The configuration of roof 10 will be described below using roof surface 10a as an example.

[0044] As shown in Figure 3, the roof 10 comprises a roof underlayment material 11 having rafters 11a fixed to beams 1a that form the frame of the building 1 and extend in a first direction D1, a main roof 11b that extends in a second direction D2 perpendicular to the rafters 11a and has an upper surface that is located above the upper surface of the rafters 11a, and a sheathing board 11c that is located on the main roof 11b, and a plurality of roof materials 12 that are arranged in the first direction D1 and the second direction D2 on the sheathing board 11c so as to form a plurality of horizontal joints 14 (joints) that are arranged at intervals L1 in the first direction D1 and extend in the second direction D2.

[0045] As shown in Figure 4, the roofing material 12 has a roofing material main body 12a extending in the first direction D1 and the second direction D2 along the sheathing board 11c, a ridge side engaging portion 12b provided at the end of the roofing material main body 12a in the +D1 direction, and an eave side engaging portion 12c provided at the end of the roofing material main body 12a in the -D1 direction and capable of engaging with the ridge side engaging portion 12b of another roofing material 12.

[0046] The ridge-side engaging portion 12b has a rising portion 12b1 extending in the -D3 direction from the end of the roof material main body 12a in the +D1 direction, and an upper-turned portion 12b2 extending in the -D1 direction from the upper end of the rising portion 12b1. The eaves-side engaging portion 12c has a downward-extending portion 12c1 extending in the +D3 direction from the end of the roof material main body 12a in the -D1 direction, and a lower-turned portion 12c2 extending in the +D1 direction from the lower end of the downward-extending portion 12c1.

[0047] Two roofing materials 12 adjacent to each other in the first direction D1 are engaged with each other by inserting the bottom turn portion 12c2 of the roofing material 12 located on the +D1 side between the top turn portion 12b2 of the roofing material 12 located on the -D1 side and the roofing material main body 12a.

[0048] Furthermore, the roofing material 12 has a roofing material fastener 12d that can be fixed to the sheathing board 11c while engaging with the ridge-side engaging portion 12b, and a screw 12e for fastening the roofing material fastener 12d to the sheathing board 11c. The roofing material fastener 12d has an engaging portion 12d1 that can engage with the ridge-side engaging portion 12b by sandwiching the upper turn-up portion 12b2 from above and below, and a fixed portion 12d2 that is connected to the engaging portion 12d1 and extends along the sheathing board 11c. The screw 12e is driven into the sheathing board 11c from above through a screw hole (not shown) formed in the fixed portion 12d2.

[0049] In the first direction D1, the roofing material 12 is fixed to the sheathing board 11c from the -D1 direction side (eaves side) toward the +D1 direction side (ridge side). Specifically, the roofing material 12 (first roofing material) located on the -D1 direction side is attached to the sheathing board 11c, and the engaging portion 12d1 of the roofing material fastener 12d is engaged with the ridge-side engaging portion 12b of the roofing material 12, and the fixed portion 12d2 is fixed to the sheathing board 11c with the screw 12e. Next, with the ridge-side engaging portion 12b of the roofing material 12 (second roofing material) located on the -D1 direction engaged with the eaves-side engaging portion 12c of the roofing material 12 located on the +D1 direction, the engaging portion 12d1 of the roofing material fastener 12d is engaged with the ridge-side engaging portion 12b of the roofing material 12 located on the +D1 direction, and the fixed portion 12d2 is fixed to the sheathing board 11c with the screw 12e. By repeating these steps, the roofing materials 12 can be attached in order from the -D1 direction side toward the +D1 direction side.

[0050] As a result of the engagement between the ridge-side engaging portion 12b and the eave-side engaging portion 12c of adjacent roofing materials 12 in the first direction D1, a horizontal joint 14 extending in the second direction D2 is formed at the boundary (the surface of the downward extending portion 12c1 facing the -D1 direction) between the roofing material body 12a of the roofing material 12 on the -D1 side and the -D1 direction end of the roofing material 12 on the +D1 side. A vertical joint 15 extending in the first direction D1 is formed between adjacent roofing materials 12 in the second direction D2.

[0051] As shown in FIG. 5, the roofing materials 12 are all the same size except for those adjacent to and adjacent to the corner ridges 10f-10i. Adjacent roofing materials 12 in the slope direction (first direction D1 on roof surface 10a) are shifted in the eaves direction by a distance equivalent to half their length in the eaves direction (second direction D2 on roof surface 10a). The lengths of the roofing materials 12 in the slope direction are all the same, including those near the corner ridges 10f-10i. Therefore, the horizontal joints 14 extending horizontally on each roof surface 10a-10d are spaced equally apart. Vertical joints 15 are formed every other horizontal joint in the first direction D1 and at the same position in the second direction D2. In this embodiment, the distance between adjacent horizontal joints 14 is defined as L1, and the distance between vertical joints 15 on roofing materials 12 of the same size is defined as L2.

[0052] The solar panels 30 are attached to the roof surface 10a of the roof 10 via mounting members 60. In this embodiment, all of the solar panels 30 have substantially the same rectangular planar shape. As shown in Figure 6, the length M2 of the solar panels 30 in the second direction D2 is the same as the spacing L2 of the vertical joints 15 of the roofing material 12.

[0053] The solar panels 30 each include a first panel main body 31 located closest to the eaves (the end position in the -D1 direction in FIG. 6 ) and at the end position along the eaves (the end position in the -D2 direction in FIG. 6 ), and a second panel main body 32 adjacent to the ridge side (+D1 direction side) of the first panel main body 31. The first panel main body 31 is shifted in the second direction D2 (-D2 direction) relative to the second panel main body 32, and thus has a protruding portion 31P that protrudes in the second direction D2 away from the second panel main body 32, using a second end portion 32a on the -D2 direction side of the second panel main body 32 in the second direction D2 as a reference. In this embodiment, a protruding dimension M3 of the protruding portion 31P in the second direction D2 based on the second end portion 32a is half the length M2 of the solar panel 30 in the second direction D2.

[0054] The roof 10 has an exposed surface 10P that is exposed upward in the second direction D2 adjacent to the second end 32a, in a region of the protruding portion 31P closer to the second panel main body 32 in the first direction D1.

[0055] The connection member 40 is used to conduct electricity generated by the solar panel 30, and may be, for example, an insulating wire. One end of the connection member 40 is connected to the connection portion 30E provided on the underside of the solar panel 30, and a connector 41 is provided on the other end. Two connection members 40 are provided on each solar panel 30. Adjacent solar panels 30 are connected in series by the connection member 40 via the connector 41. Of the solar panels 30 connected in series, one of the connection members 40 of the terminal solar panel 30 penetrates the roof 10 and is introduced into the interior of the building 1.

[0056] In this embodiment, the connecting member 40 that connects the first panel body 31 and the second panel body 32 extends from the first panel body 31 to the second panel body 32 over the exposed surface 10P of the roof 10.

[0057] The covering member 50 is provided on the roof 10 so as to cover the exposed portion 40P of the connecting member 40 that is disposed on the exposed surface 10P of the roof 10. Specifically, as shown in FIG. 6 , the covering member 50 is attached to the roof 10 in a state in which only a region 50P is exposed in a plan view in a direction perpendicular to the first direction D1 and the second direction D2, i.e., in a third direction D3, defined by a range in the first direction D1 corresponding to the spacing between two of the horizontal joints 14 and a range in the second direction D2 having a dimension equivalent to that of the protruding portion 31P of the first panel main body 31 in the plan view. Specifically, the length N1 of the range in the first direction D1 of the region 50P corresponds to the spacing (L2 × 2) between the two horizontal joints 14a, 14b, and the length N2 of the range in the second direction D2 of the region 50P corresponds to the protruding dimension M3 of the protruding portion 31P.

[0058] In addition, the end 31a of the first panel body 31 farthest from the second panel body 32 in the first direction D1 is arranged along the distal joint 14c, which is arranged away from the covering member 50 at a distance M1 that is the same as the distance (L2×2, N1) between the two horizontal joints 14a, 14b, from the proximal joint 14a that is closest to the first panel body 31 of the two horizontal joints 14a, 14b.

[0059] 6 and 7, the first panel main body 31 has a first extending portion 31Q that extends from the proximal joint 14a toward the second panel main body 32 in the first direction D1. The covering member 50 covers the first extending portion 31Q so that only a region 31R in the first direction D1 that corresponds to the distance (M1) between the proximal joint 14a and the distal joint 14c in the first panel main body 31 is exposed in a plan view. In this embodiment, as shown in FIG. 6, the second panel main body 32 also covers the first extending portion 31Q in the same way as the covering member 50 so that only the region 31R of the first panel main body 31 is exposed.

[0060] 6, the end 32c of the second panel main body 32 that is closer to the first panel main body 31 is disposed along the proximal joint 14a of the two horizontal joints 14a, 14b that is closer to the first panel main body 31. The second panel main body 32 also has a second extension portion 32Q that protrudes in the first direction D1 from the horizontal joint 14b (the joint other than the proximal joint 14a) of the two horizontal joints 14a, 14b in a direction away from the first panel main body 31 (+D1 direction). The roof structure 2 further includes a covering member 50A (second covering member 57) that covers the second extension portion 32Q so that only the region 32R corresponding to the distance (L2 × 2, N1) between the two horizontal joints 14a, 14b is exposed in a plan view. In addition, at least a portion of the first panel body 31, the second panel body 32, and the ends of the second panel body 32 in the second direction D2 (the sides extending in the first direction D1) are arranged along the vertical joints 15 of the roofing material 12.

[0061] The solar panel 30 further includes a third panel main body 33 adjacent to the ridge side (+D1 direction side) of the second panel main body 32. The second panel main body 32 has a protruding portion 32P that protrudes in a direction away from the third panel main body 33 in the second direction D2, based on an end 33a of the third panel main body 33 in the -D2 direction in the second direction D2. The protruding dimension of the protruding portion 32P is the same as the protruding dimension M3 of the protruding portion 31P. In this embodiment, like the covering member 50, the third panel main body 33 also covers the second extending portion 32Q so that only the region 32R of the second panel main body 32 is exposed. That is, the third panel main body 33 also functions as the second covering member 57.

[0062] The covering member 50A is provided in a region of the protruding portion 32P closer to the third panel main body 33 in the first direction D1, and is provided to cover the exposed surface 10Q of the roof 10 that is exposed upward adjacent to the end portion 33a in the second direction D2. In this embodiment, the connecting member 40 is not disposed on this exposed surface 10Q.

[0063] As shown in Figures 2 and 6, the solar panel 30 in the roof structure 2 of this embodiment further includes a plurality of first-row panel bodies 36 adjacent to the first panel body 31 in the second direction D2 and arranged in a row in the second direction D2 away from the protrusion 31P, and a plurality of second-row panel bodies 37 adjacent to the second panel body 32 in the second direction D2 and arranged in a row in the second direction D2 away from the exposed surface 10P.

[0064] The first panel body 31 and the plurality of first-row panel bodies 36 are electrically connected in series by the connecting member 40. Similarly, the second panel body 32 and the plurality of second-row panel bodies 37 are electrically connected in series by the connecting member 40. The first panel body 31 and the second panel body 32 are also electrically connected in series by the connecting member 40.

[0065] Furthermore, the one of the multiple first-row panel bodies 36 arranged furthest in the +D2 direction and the one of the multiple second-row panel bodies 37 arranged furthest in the +D2 direction are both arranged to protrude in the +D2 direction relative to the solar panel 30 adjacent on the ridge side (+D1 direction side) of these solar panels 30. Furthermore, the two solar panels 30 arranged second from the ridge side in the second direction D2 in the first direction D1 are also arranged to protrude in the +D2 direction or -D2 direction relative to the solar panel 30 arranged furthest from the ridge side. In this embodiment, covering members 50 of the same size and shape are provided on the ridge sides of the protruding portions of these protruding solar panels 30.

[0066] Additionally, an uppermost covering member 58 is provided on the ridge side of the solar panel 30 that is provided closest to the ridge. An opening is provided in the portion of the roof 10 covered by the uppermost covering member 58 to allow the connection member 40 to be drawn into the interior of the building 1. The exposed range of the uppermost covering member 58 in a plan view is defined by a range in the second direction D2 that is substantially the same as the length M2 in the second direction D2 of the exposed range of the solar panel 30, and a range in the first direction D1 that is substantially the same as the length N1 in the first direction D1 of the exposed range of the covering member 50.

[0067] The structure of the covering member 50 and the relationship between the covering member 50 and the first roofing material 12A and the second roofing material 12B will be described.

[0068] 7, the first roof material 12A has a first roof edge 12A1 in the first direction D1 (+D1 direction). The second roof material 12B has a second roof edge 12B1 that is adjacent to the first roof material 12A in the first direction D1 (+D1 direction) and overlaps the first roof edge 12A1 from above.

[0069] The covering member 50 has an inserted portion 51 inserted between the first roof edge 12A1 and the second roof edge 12B1, and an exposed portion 52 extending from the inserted portion 51 in a direction away from the second roof material 12B (-D1 direction) and having an area corresponding to the distance (L2 x 2, N1) between the two horizontal joints 14a, 14b in a planar view.

[0070] The exposed portion 52 has an extension portion 52a extending from the inserted portion 51 along the upper surface of the first roof material 12A, and an accommodation chamber forming portion 52b extending from the extension portion 52a in a direction away from the inserted portion 51 and the roof material 12 so as to form an accommodation chamber 3 for accommodating the connecting member 40 between the inserted portion 51 and the roof material 12. The accommodation chamber 3 accommodates the exposed portion 40P of the connecting member 40 arranged on the exposed surface 10P of the roof 10.

[0071] The covering member 50 also has side walls 53 that extend from both ends of the storage chamber forming portion 52b in the second direction D2 toward the roof material 12 and close both ends in the second direction D2 of the storage chamber 3 formed between the storage chamber forming portion 52b and the roof material 12. The side walls 53 are provided with outlet holes 53a that allow the connecting member 40 to be guided in the second direction D2.

[0072] The covering member 50 has an engaging portion 54 that is provided at the end of the storage chamber forming portion 52b in the -D1 direction and is engageable with the mounting member 60 described below. The engaging portion 54 has a downward extending portion 54a that extends in the +D3 direction from the end of the storage chamber forming portion 52b in the -D1 direction, and a downward turning portion 54b that extends in the +D1 direction from the lower end of the downward extending portion 54a.

[0073] The extension 52a is large enough to cover the entire upper surface of the first roofing material 12A in the first direction D1. The boundary line 52c between the extension 52a and the storage chamber forming portion 52b is provided along the horizontal joint 14 formed by the end of the first roofing material 12A in the -D1 direction when the extension 52a is arranged along the upper surface of the first roofing material 12A.

[0074] Further, the extension 52a is joined to the first roof material 12A in a state of being in close contact with the upper surface of the first roof material 12A. There are no particular limitations on the joining method, and for example, an adhesive or double-sided tape can be used.

[0075] The storage chamber forming portion 52b extends at an angle from the extension portion 52a so as to move away from the roof material 12 in the direction away from the inserted portion 51 (the -D1 direction). A reinforcing member 55 is provided on the underside of the portion of the storage chamber forming portion 52b near the boundary line 52c, at a position away from the mounting member 60 in the +D1 direction, and extends to the upper surface of the first roof material 12A.

[0076] The covering member 50 is attached to the roof 10 as follows: The inserted portion 51 and the extension portion 52a are positioned along the first roof material 12A. Then, the inserted portion 51 is inserted between the first roof edge 12A1 and the second roof edge 12B1, and the engaging portion 54 is engaged with the attached portion 63 of the attachment member 60, which will be described later. This allows the covering member 50 to be attached to the roof 10.

[0077] The mounting member 60 will now be described. Figure 8 shows the mounting member 60 without the attached portion 63, with (a) being a plan view and (b) being a side view. As shown in Figures 4, 7, and 8, the mounting member 60 has a fixing portion 61 fixed to the roof 10, an extending portion 62 extending from the fixing portion 61 along the upper surface of the roof material 12, an attached portion 63 provided at the end of the extending portion 62 in the +D1 direction and to which the covering member 50 is attached, a holding portion 64 that holds the connecting member 40 between the covering member 50 attached to the attached portion 63 and the roof 10, and a mounting screw 65 for fixing the fixing portion 61 to the roof 10.

[0078] The mounting portion 63 has a base 63a fixed to the end of the extending portion 62 in the +D1 direction, a first rising portion 63b extending in the -D3 direction from the base 63a, a first clamping portion 63c extending in the -D1 direction from the tip of the first rising portion 63b so as to form a gap in the third direction D3 between the base 63a and the first clamping portion 63c, a second rising portion 63d extending in the -D3 direction from the end of the -D1 direction of the first clamping portion 63c, and a second clamping portion 63e extending in the +D1 direction from the upper end of the second rising portion 63d. The mounting portion 63 is fixed to the extending portion 62 by threading a screw 67 into the base 63a through a screw hole 62a provided in the extending portion 62.

[0079] As shown in Figures 4 and 7, the extending portion 62 clamps the end of the solar panel 30 in the +D1 direction (the first extending portion 31Q of the first panel main body 31 and the second extending portion 32Q of the second panel main body 32) between itself and the first clamping portion 63c. Also, as shown in Figure 4, the first clamping portion 63c clamps the end of the solar panel 30 in the -D1 direction between itself and the second clamping portion 63e. Furthermore, with the first clamping portion 63c, the second rising portion 63d, and the second clamping portion 63e inserted into the engaging portion 54 of the covering member 50, the covering member 50 is attached to the mounting member 60 so as to prevent the end of the covering member 50 in the -D1 direction from lifting up from the roof material 12.

[0080] The holding portion 64 has a shape for holding a portion of the connecting member 40 in a state in which the portion of the connecting member 40 is arranged in the groove 64a along the second direction D2. Specifically, the holding portion 64 has a plurality of grooves 64a into which the connecting members 40 can be fitted. The holding portion 64 also has return portions 64b for narrowing the opening area of ​​the upper portions of the grooves 64a. The return portions 64b prevent the connecting members 40 held in the grooves 64a from slipping out of the holding portion 64.

[0081] The fixing portion 61 of the mounting member 60 is arranged along the roof material 12, with the extension portion 62 abutting against the engagement portion between the ridge-side engagement portion 12b of two roof materials 12 adjacent in the first direction D1 and the roof material fastener 12d. In this state, the mounting member 60 is fixed to the roof 10 by driving a mounting screw 65 into the roof material 12 and the sheathing board 11c through the through hole 61a provided in the fixing portion 61.

[0082] Not only the covering member 50 and the uppermost covering member 58, but also the solar panel 30 is attached to the roof 10 by the attachment member 60. The method of attaching the solar panel 30 will be described with reference to Figures 3 and 4 .

[0083] First, the -D1 end of the solar panel 30 is clamped between the first clamping portion 63c and the second clamping portion 63e of the mounting member 60 with the mounted portion 63 attached. Next, the +D1 end of the solar panel 30 is placed on the upper surface of the clamping member 68 of another mounting member 60 located on the +D1 side where the mounted portion 63 is not attached. Then, the mounted portion 63 is attached to the extending portion 62 with the screw 67. In this way, the +D1 end of the solar panel 30 (first extending portion 31Q of the first panel main body 31) is clamped between the clamping member 68 and the first clamping portion 63c, and the solar panel 30 can be attached to the roof 10.

[0084] <Actions and Effects> In the roof structure 2 according to the above embodiment, the first panel body 31 is positioned shifted in the second direction D2 relative to the second panel body 32. Therefore, the area where the first panel body 31 and the second panel body 32 are adjacent in the first direction D1 is narrower than when the second end 32a and the end of the first panel body 31 in the second direction D2 are positioned at the same position. In this situation where the area below both the first panel body 31 and the second panel body 32 is limited, the first panel body 31 and the second panel body 32 can be reliably connected by positioning the connecting member 40 over the exposed surface 10P of the roof.

[0085] Furthermore, a covering member 50 is provided on the roof 10 so as to cover the exposed portion 40P that is located on the exposed surface 10P of the connecting member 40. Therefore, by covering the connecting member 40, a good aesthetic appearance can be obtained, and by protecting the connecting member 40 from the external environment such as wind, rain, and direct sunlight, deterioration of the connecting member 40 can be suppressed.

[0086] According to the roof structure 2 of the above embodiment, the mounting member 60 has a holding portion 64 that holds the connecting member 40. This makes it possible to prevent problems such as the connecting member 40 being damaged when it moves and comes into contact with surrounding objects. Furthermore, since the holding portion 64 is provided on the mounting member 60 that attaches the covering member 50 to the roof 10, the holding portion 64 that prevents damage to the connecting member 40 as described above can also be used as the mounting member 60.

[0087] According to the roof structure 2 according to the above embodiment, the holding portion 64 can hold the connecting member 40 arranged on the exposed surface 10P in an orientation facing the second panel main body 32. Therefore, in a situation where one end of the connecting member 40 is detached from the second panel main body 32, such as during initial construction or maintenance of the roof structure 2, it is possible to prevent the connecting member 40 from moving in an unintended direction.

[0088] According to the roof structure 2 of the above embodiment, only the range in the first direction D1 corresponding to the distance (L2 × 2) between the two horizontal joints 14a, 14b in the covering member 50 is exposed in a plan view seen in the third direction D3, so the covering member 50 can be installed while maintaining the regularity of the roof material 12. This reduces the sense of incongruity that the covering member 50 gives to the roof material 12 when installed on the roof 10, and allows the aesthetic appearance of the roof structure 2 to be maintained.

[0089] Furthermore, according to the roof structure 2 according to the above embodiment, in a plan view seen in the third direction D3, only the range in the second direction D2 from the second end 32a of the covering member 50 to the protruding portion 31P of the first panel main body 31 is exposed. Therefore, the covering member 50 is arranged so as to fill in the step formed between the first panel main body 31 and the second panel main body 32, and the covering member 50 can be provided without impairing the aesthetic appearance of the roof structure 2.

[0090] According to the roof structure 2 of the above embodiment, the exposed areas of the first panel body 31 and the covering member 50 in the first direction D1 can be aligned in a plan view in the third direction D3. This allows the first panel body 31, in addition to the covering member 50, to be provided while maintaining the regularity of the roof material 12, making it possible to maintain the aesthetic appearance of the roof structure 2 while protecting the connecting member 40.

[0091] According to the roof structure 2 of the above embodiment, the exposed areas of the covering member 50 and the second panel main body 32 in the first direction D1 can be aligned in a plan view in the third direction D3. This allows the covering member 50 and the second panel main body 32 to be provided while maintaining the regularity of the roof material 12, making it possible to maintain the aesthetic appearance of the roof structure 2 while protecting the connecting members 40.

[0092] According to the roof structure 2 of the above embodiment, by inserting the inserted portion 51 between the first roof end portion 12A1 and the second roof end portion 12B1, the covering member 50 can be attached to the roof with the exposed portion 52 exposed between the two horizontal joints 14a, 14b.

[0093] According to the roof structure 2 of the above embodiment, the extension portion 52a extends from the inserted portion 51 along the upper surface of the first roof material 12A, so that the extension portion 52a can come into contact with the upper surface of the first roof material 12A when the inserted portion 51 is inserted between the first roof edge portion 12A1 and the second roof edge portion 12B1. Therefore, the inserted state of the inserted portion 51 can be stably supported by the extension portion 52a.

[0094] Furthermore, since it has the storage chamber forming portion 52b, it is possible to form the storage chamber 3 for accommodating the connecting member 40 by the storage chamber forming portion 52b while realizing stable support of the inserted state of the inserted portion 51 as described above.

[0095] According to the roof structure 2 of the above embodiment, the extension 52a covers the entire upper surface of the first roof material 12A, and the boundary line 52c between the extension 52a and the storage chamber forming portion 52b is provided along the horizontal joint 14. Therefore, the storage chamber 3 for the connecting member 40 can be formed without disrupting the regularity of the multiple roof materials 12, that is, the regularity of the horizontal joint 14. Therefore, it is possible to achieve stable support in the inserted state and the formation of the storage chamber 3 by the extension 52a described above, while maintaining the aesthetic appearance of the roof structure 2.

[0096] According to the roof structure 2 of the above embodiment, since the storage chamber forming portion 52b is inclined, the storage chamber 3 can be formed while preventing deterioration in the aesthetic appearance of the roof structure 2 due to a sudden change in shape of the covering member 50.

[0097] According to the roof structure 2 of the above embodiment, the extension portion 52a is joined to the first roof material 12A, so that the inserted state of the inserted portion 51 can be more reliably maintained.

[0098] Furthermore, because the extension 52a is joined in a state of intimate contact with the upper surface of the first roof material 12A, it is possible to prevent rainwater and the like from entering between the covering member 50 and the first roof material 12A.

[0099] According to the roof structure 2 of the above embodiment, the first panel group including the first panel body 31 and the plurality of first-row panel bodies 36, which are electrically connected in series, and the second panel group including the second panel body 32 and the plurality of second-row panel bodies 37, which are electrically connected in series, can be electrically connected in series by the connecting members. In other words, the panel bodies belonging to the first panel group are connected in series from the first-row panel body 36 farthest from the first panel body 31 to the first panel body 31, the first panel body 31 and the second panel body 32 are electrically connected by the connecting members, and the panel bodies belonging to the second panel group are connected in series from the second panel body 32 to the second-row panel body 37, which is farthest from the second panel body 32. According to the roof structure 2 of the above embodiment, the plurality of panel bodies included in the first panel group and the second panel group can be efficiently connected in series as described above.
