Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(Embodiment 1)
The roof wiring structure of the first embodiment is applied to the wiring of the solar cell module PV installed on the roof RF of the building BL shown in FIG.

FIG. 1 is a schematic plan view showing a roof RF of a building BL, and for this building BL, for example, a unit building constructed by a plurality of building units U can be used. The building unit U has a well-known rectangular parallelepiped steel frame structure in which four columns arranged at the corners and the upper ends and the lower ends of the columns are connected by beam members. Further, as such a building BL, one in which a steel frame is assembled at a construction site can be used without using the building unit U.

Further, the building BL is a one-story building or a multi-story building, and the roof RF provided on the upper surface thereof is called a substantially horizontal flat roof.

Further, in the first embodiment, the roof RF of the building BL is provided on the first roof portion RF1 provided on the upper part of the first unit group UG1 and the second roof RF provided on the upper part of the second unit group UG2. It is formed by combining with the roof portion RF2 of. Further, the first roof portion RF1 and the second roof portion RF2 are provided with a first building RD1 and a second building RD2 at the center in the left-right direction of the paper surface, respectively. The roof RF is given a roof gradient in the direction of the arrow RSL with the RD1 and RD2 of each building on the water. Further, the solar cell module PV is also inclined in the same direction as the roof slope.

The first unit group UG1 and the second unit group UG2 are installed so as to be displaced in the orthogonal direction in the direction along the RD1 and RD2 of each building. Therefore, the first roof portion RF1 and the second unit group UG2 are installed. The roof portion RF2 of No. 2 is connected to the roof portions RF2 in a state where the positions of both buildings RD1 and RD2 are shifted in the orthogonal direction.

Solar cell modules PV are symmetrically installed on the roof RF with RD1 and RD2 in each building. A routing cable LC is continuously provided on the pair of solar cell modules PV and the drawing cable PLC drawn from the PV.

The routing cable LC is routed along the ridges RD1 and RD2 and is connected to the joint box JB provided at the end of the ridge RD1 of the first unit group UG1. Further, the routing cable LC was laid out in a direction orthogonal to the ridges RD1 and RD2 at the portion where the positions of the ridges RD1 and RD2 were shifted from the ridge wiring section RWS laid out in each ridge RD1 and RD2. A horizontal pulling portion LDS is provided.

The distance between the solar cell module PV and the building unit U along the ridges RD1 and RD2 is relatively large, and the distance between the gaps SP1 formed between the central units of the group of four solar cell module PVs is relatively large. It is formed narrowly. On the other hand, in the unit groups UG1 and UG2, the gap SP2 formed between the units of one group of the four solar cell modules PV and the gap SP3 formed between the units of both unit groups UG1 and UG2. The intervals are relatively wide.

Next, the wiring structure of the routing cable LC will be described. First, the wiring structure in the building wiring section RWS arranged at the positions of the ridges RD1 and RD2 is shown in cross-sectional view at the positions of the S2-S2 lines in FIG. It will be described together with the structure of the roof RF based on FIG.

Roof beams H, H having a substantially U-shaped cross section are provided at the upper end of the building unit U, and of these roof beams H, H and their paired roof beams H, H (not shown). Roof frames 1 and 1 are laid on top.
The roof frames 1 are arranged in parallel at intervals in the direction orthogonal to the paper surface of FIG. 2 (the extending direction of the roof beams H), and the field plate 11 is supported by these roof frames 1. Further, the upper surface of the field board 11 is covered with a waterproof sheet 14 such as polyethylene roofing. Since the waterproof sheet 14 is laid up to the edge of the field plate 11, the entire surface of the field plate 11 is covered with the waterproof sheet 14.

Then, the roofing material 12 is installed on the waterproof sheet 14. The roofing material 12 is formed of, for example, a hot-dip aluminum-plated steel plate or a synthetic resin having excellent waterproof performance and corrosion resistance.

In the roofing material 12, the standing wall portion 121 is raised substantially vertically from both side edges of the rectangular flat plate-shaped portion overlapped on the field plate 11, and further, the standing wall portion 121 is raised inward at a substantially right angle from the upper end of the standing wall portion 121. The edge 122 is overhanging (see FIG. 4). Further, in the solar cell module PV, the solar cell support metal fittings 13 are provided at positions near both ends in the direction along the roof slope, and the solar cell support metal fittings 13 are fixed to the roof frame 1.

The ridge wiring section RWS routed to the ridge RD1 (RD2) in the routing cable LC is laid out along the wiring accommodating section 30 formed between the ridge cover 2 and the ridge wiring blindfold cover 3. There is. The wiring accommodating portion 30 is raised and arranged at a position higher than that of the roofing material 12.

As shown in FIGS. 3 and 4, the ridge cover 2 includes a wiring base portion 21 and pedestal portions 22 and 22 provided on both side edges of the wiring base portion 21 in the width direction.

The wiring base portion 21 is formed in a substantially rectangular shape when viewed from above, and has hanging portions 23 and 23 hanging from both side edges in the width direction (direction orthogonal to the direction along the ridge RD1) and both end portions in the longitudinal direction (FIG. In 3, only one end is shown), and the end wall portion 24 is provided.

A pair of cradle portions 22 are provided at intervals in the width direction, and a plurality of pedestal portions 22 are provided at predetermined intervals in the longitudinal direction of the wiring base portion 21. For example, as shown in FIG. 5, about 3 locations (6 locations on both sides) are provided with respect to the length of the edge of one solar cell module PV. Further, as shown in FIG. 3, the pedestal portion 22 is formed in a hat cross-sectional shape, and the flange portions 22a and 22a on both sides thereof are fixed to the wiring pedestal portion 21 by rivets.

Then, the ridge wiring blindfold cover 3 is placed on the upper surface 22b of the pedestal portion 22, and the wiring accommodating portion 30 is formed between the wiring pedestal portion 21 and the ridge wiring blindfold cover 3. The ridge wiring blind cover 3 is formed into a hat cross-sectional shape by a gate-shaped portion 31 having a gate-shaped cross section and flange portions 32, 32 protruding on both sides in the width direction thereof (orthogonal direction in the direction along the ridge RD1). Has been done. Then, each flange portion 32 is connected by a drill screw 33 in a state of being overlapped with the upper surface 22b of the pedestal portion 22. The drill screw 33 is screwed into a hole formed through the upper surface 22b of the pedestal portion 22.

In the wiring accommodating portion 30 formed in this way, as shown in FIG. 1, the number of routing cables LC to be arranged increases as the joint box JB is approached from the side far from the joint box JB.

Further, in the gaps SP1 and SP2 formed between the solar cell modules PV in the unit groups UG1 and UG2, as shown in FIG. 6, a blind cover joint member 130 is provided to cover the routing cable LC. Although FIG. 6 shows the blind cover joint member 130 provided in the relatively wide gap SP2, the relatively narrow gap SP1 also has the same cross section as the blind cover joint member 130, although not shown. It is assumed that a blind cover joint member having a short shape and a short length is provided.

The blind cover joint member 130 is formed in a hat cross-sectional shape including a gate-shaped portion 131 and flange portions 132, 132, similarly to the ridge wiring blind cover cover 3. Then, in a state where both ends of the blind cover joint member 130 in the longitudinal direction are overlapped on the end of the ridge wiring blind cover 3 from above, the flange portion 132 is placed on the upper surface 22b of the pedestal portion 22 together with the flange portion 32. It is fixed by the drill screw 33.

In the gaps SP1 and SP2 between the building units U, the portion outside the portion where the blind cover joint member 130 for covering the routing cable LC is provided is covered with the vertical covers 210 and 220 shown in FIGS. 7 and 8. It has been. The vertical cover 210 shown in FIG. 7 covers a relatively narrow gap SP1, and the vertical cover 220 shown in FIG. 8 covers a relatively wide gap SP2.

First, the structure of the relatively narrow gap SP1 shown in FIG. 7 will be described. The vertical cover 210 covers the gap SP1 and is fixed to the upper ends of the roof frames 101 and 101, and is a flat upper plate portion 211 and hanging pieces 212 and 212 hanging from both side edges of the upper plate portion 211. Therefore, it is formed in a substantially inverted U-shaped cross-sectional shape.

The roof frames 101 and 101 are fixed to the substantially U-shaped roof panel connecting metal fittings 103 fixed to the connecting beams 102 with bolts and nuts in a state of being arranged at intervals. Further, the roof panel connecting metal fitting 103 is also fixed to the connecting beam 102 by bolts and nuts. The connecting beam 102 is bridged over a girder roof beam GH (see FIG. 8) similar to the above-mentioned roof beam H provided on the girder side.

The roof frame 101 supports the field plate 11 and the solar cell module PV. The field board 11 is supported by a field board receiving bar 104 fixed to an intermediate portion in the vertical direction of the roof frame 1. The field board receiving bar 104 is attached at an angle along the above-mentioned roof slope (arrow RSL), and the field board 11 is supported by the inclined field board receiving bar 104 to have a roof slope. Is given. Further, the solar cell module PV is supported by a solar cell support metal fitting 13 fixed to the upper flange 1f at the upper end of the roof frame 1.

Further, as shown in the drawing, the vertical cover 210 is attached so as to sandwich the pair of solar cell support metal fittings 13 by the pair of hanging pieces 212 and 212. Further, a sealing material 213 made of a foamed resin material and having adhesiveness is provided on the back surface of the vertical cover 210 including between the vertical cover 210 and the upper flange 1f on the upper side of the roof frame 1.

Next, the structure of the relatively wide gap SP2 will be described with reference to FIG.
In the gap SP2, a pair of roof frames 101 and 101 provided at the ends of connecting beams 102 provided in different building units U are arranged so as to face each other. The roof frame 101 is fixed to an L-shaped cross-sectional bracket 105 fixed to the end of the connecting beam 102 by bolts and nuts with structural screws. A vertical cover 220 is provided on the pair of roof frames 101, 101 facing each other with the gap SP2 interposed therebetween.

Like the vertical cover 210, the vertical cover 220 is formed in a substantially inverted U-shaped cross section by the upper plate portion 221 and the hanging pieces 222 and 222. This vertical cover 220 is different from the vertical cover 210 in which the upper plate portion 211 is provided substantially horizontally, and the upper plate portion 221 is provided with a water gradient that descends in the direction of the arrow WG. That is, since the space between the gaps SP2 is wide, a water gradient is applied to ensure the waterproofness of the vertical cover 220 so that water does not collect on the vertical cover 220. The water gradient is orthogonal to the roof gradient in the direction of the arrow RSL (see FIG. 1).

Further, the lower surface of the upper plate portion 221 is supported by the field plate 223 to ensure the strength. Therefore, in order to give a water gradient to the vertical cover 220, the field plate 223 is attached at an inclination. That is, both side portions of the field plate 223 in the width direction (horizontal direction of the paper surface) are supported by the field plate metal fittings 224 and 224 having an inverted L-shaped cross section attached to the pair of roof frames 101 and 101. As shown in the figure, the field plate metal fittings 224 and 224 are attached at different heights. Further, a spacer 227 is provided on the upper flange 101f of the roof frame 101 on the upstream side of the water gradient.

The upper plate portion 221 of the vertical cover 220 has a lower surface supported by a spacer 227 at the upstream end portion of the water gradient, a middle portion supported by a field plate 223, and an upper flange at the downstream end portion of the water gradient. It is directly supported by 101f, which imparts a water gradient. With this water gradient applied, the vertical cover 220 is fixed to the field plate metal fittings 224 and 224 with a drill screw 224a. A sealing material 228 made of highly foamed resin is provided between the lower surface of the upper plate portion 221 and the upper surface of the field plate 223.

Next, in the routing cable LC, the wiring structure in the horizontal pulling portion LDS arranged in the portions where the positions of the ridges RD1 and RD2 and the ridges RD1 and RD2 are shifted will be described.

FIG. 9 is a perspective view showing a wiring state of the lateral pulling portion LDS of the pulling cable LC. The routing cable LC to which the ridge RD2 of the second unit group UG2 is arranged builds a gap SP3 between the first unit group UG1 and the second unit group UG2 from the end of the wiring accommodating portion 30. It passes in the orthogonal direction of RD1 and RD2, and is arranged in the wiring accommodating portion 30 of the building RD1 of the first unit group UG1.

Further, as shown in the drawing, the routing cable LC is arranged along the upper surface of the vertical cover 220 similar to that provided in the gap SP2 described above. The structure of this portion will be described with reference to the cross-sectional view of FIG. 10, which is a cross section of the horizontal pulling portion LDS (cross section at the position of the S10-S10 line in FIG. 1).

The vertical cover 220 is formed in a substantially inverted U-shaped cross section by the upper plate portion 221 and the hanging pieces 212 and 212. The vertical cover 220 is provided with a water gradient that descends in the left direction in the drawing, that is, in the direction of the first unit group UG1.

Here, the difference from the vertical cover 220 provided in the gap SP2 (see FIG. 8) is that a pedestal portion 225 and 226, which will be described later, is provided on the upper plate portion 221 and the upper plate portion 221 is used as a wiring base. This is a point used as a part. Further, the vertical cover 220 provided with the pedestal portions 225 and 226 is provided in a range sandwiched between the ridges RD1 and RD2 in the direction orthogonal to the ridges RD1 and RD2. The other gap SP3 has the same structure as the gap SP2 (see FIG. 8) described above.

In the vertical cover 220, the lower surface of the upper plate portion 221 is supported by the field plate 223. Since the mounting structure of the field plate 223 and the support structure of the vertical cover 220 are the same as those of the gap SP2 described above, they will be briefly described below. Both sides of the field board 223 are supported by field board metal fittings 224 and 224 having an inverted L-shaped cross section attached to a pair of roof frames 101 and 101. These field plate metal fittings 224 and 224 are also attached at different heights like the gap SP2. Further, the upper plate portion 221 of the vertical cover 220 is provided with a water gradient by being directly supported by the spacer 227 on the upstream side of the water gradient and directly supported by the upper flange 101f on the downstream side of the water gradient. There is. A sealing material 228 made of highly foamed resin is provided on the lower surface of the upper plate portion 221 and the upper surface of the field plate 223. The vertical cover 220 is screwed to the field plate metal fittings 224 and 224.

The features of the vertical cover 220 provided on the horizontal pulling portion LDS will be described below.
A pair of pedestal portions 225 and 226 are provided on the upper surface of the upper plate portion 221 of the vertical cover 220 at predetermined intervals in the width direction. These pedestal portions 225 and 226 are formed so that the height of the pedestal portion 226 on the side closer to the second unit group UG2 is lower than the height of the pedestal portion 225 on the side closer to the first unit group UG1. Therefore, the height of the upper surface is almost the same.

Further, as shown in FIG. 9, a plurality of sets of pedestal portions 225 and 226 are provided at predetermined intervals along the lateral pulling portion LDS. The routing cable LC is arranged between the pair of pedestals 225 and 226 in the width direction. Further, at one end of the horizontal pulling portion LDS, as shown in an enlarged manner in FIG. 11, the pulling cable LC is routed with a pedestal portion 226 sandwiched between them so as to maintain a constant distance between them. Similarly, as shown in FIG. 9, the end portion on the opposite side of the lateral pulling portion LDS is also routed so as to sandwich the pedestal portion 225 in between.

Since the height of the upper plate portion 221 of the vertical cover 220 of the horizontal pulling portion LDS is different from the height of at least one of the upper surfaces of the building covers 2 of each building RD1 and RD2, the routing cable LC is arranged. It is arranged with a slight vertical displacement.

Further, a horizontal pulling portion wiring blindfold cover 300 is provided on the upper side of the vertical cover 220, and as shown in FIG. 10, a wiring accommodating portion 30b is formed between the vertical cover 220 and the horizontal pulling portion wiring blindfold cover 300. There is. The horizontal pulling portion wiring blindfold cover 300 is fixed to the pedestal portions 225 and 226 provided on the vertical cover 220 by a drill screw 305.

As shown in FIG. 13, the horizontal pulling portion wiring blindfold cover 300 includes a straight cover portion 310, corner cover portions 320 and 320, and joint cover portions 330 and 330. The cover portions 310, 320, and 330 are formed in a common cross-sectional shape and are provided continuously.

The cross-sectional shape will be described on behalf of the linear cover portion 310 shown in FIG. The straight cover portion 310 includes a gate-shaped gate-shaped portion 301, lateral flange portions 302 and 302 extending outward from both ends in the width direction (left-right direction of the paper surface) of the gate-shaped portion 301, and tips of both flange portions 302. The lower flange portions 303 and 304 extending downward from the surface form a substantially hat cross-sectional shape. In the lower flange portions 303 and 304, the lower flange portion 303 on the first unit group UG1 side on the downstream side of the water gradient is formed to have a longer vertical dimension than the lower flange portion 304 on the opposite side. ..

Then, as shown in FIG. 10, the straight cover portion 310 has a gate-shaped portion 301 fixed to the pedestal portion 225 and 226 by a drill screw 305. Then, in this fixed state, the lower flange portions 303 and 304 are placed in contact with or close to both side edges of the upper plate portion 221 of the vertical cover 220 in the width direction. Therefore, the routing cable LC is covered by the straight line cover portion 310.

As shown in FIG. 13, since the joint cover portion 330 is also continuously provided on the straight cover portion 310, it is formed in the same cross-sectional shape as the straight cover portion 310.
The corner cover portion 320 is a ridge side that is continuously attached to the gap side portion 321 that is continuously attached to the joint cover portion 330 and the ridge wiring blindfold cover 3 (see FIG. 2) that covers the above-mentioned ridges RD1 and RD2. A unit 322 is provided. The gap side portion 321 is formed in the same cross-sectional shape as the straight cover portion 310, and the ridge side portion 322 is formed in the same cross-sectional shape as the ridge wiring blind cover 3 so as to be continuous with the ridge wiring blind cover 3. There is.

Next, the fixing structure of the horizontal pulling portion wiring blindfold cover 300 will be described together with the procedure.
When fixing the horizontal pulling portion wiring blindfold cover 300, first, the straight cover portion 310 and the corner portion cover portion 320 are fixed.

As described above, the straight cover portion 310 fixes the portal portion 301 to the pedestal portion 225 and 226 with the drill screw 305.

Next, the corner cover portion 320 is fixed, and the corner cover portion 320 is fixed to the pedestal portions 225, 226 and the pedestal portions 22, 22. That is, the ridge side portion 322 of the corner cover portion 320 is fixed to the pedestal portions 22 and 22 provided on the ridge cover 2 together with the ridge wiring blindfold cover 3 by a drill screw 33. Further, in this state, the gap side portion 321 of the corner cover portion 320 is arranged on the pedestal portions 225 and 226 provided on the vertical cover 220.

When the corner cover portion 320 is arranged in this way, as shown in FIG. 13, a gap SP4 is generated between the gap side portion 321 of the corner cover portion 320 and the straight cover portion 310. That is, the gap side portion 321 of the straight cover portion 310 and the corner cover portion 320 is formed so as to generate a gap SP4 at the time of mounting.

The joint cover portion 330 covers the gap SP4, and is further attached so as to overlap the end portion of the straight cover portion 310 and the end portion of the gap side portion 321 of the corner cover portion 320. That is, the end of the joint cover portion 330 on the straight cover portion side is fixed to the pedestal portion 225 and 226 together with the end portion of the straight cover portion 310 by the drill screw 305. On the other hand, the end portion of the joint cover portion 330 on the corner cover portion side is fixed to the pedestal portion 225 and 226 together with the gap side portion 321 of the corner cover portion 320 by the drill screw 305. When fixing the joint cover portion 330, as shown in the drawing, a sealing material (modified silicone) is applied to the end portion of the straight cover portion 310 and the end portion of the gap side portion 321 of the corner cover portion 320. After applying 306, fix it to ensure waterproofness.

As described above, since the horizontal pulling portion wiring blindfold cover 300 is continuously provided with the blindfold cover 3 provided in the ridges RD1 and RD2, the routing cable LC is continuously provided with these ridge wiring blindfold covers 3 and 300. And be covered.

Next, the operation of the roof wiring structure of the first embodiment will be described.

The solar cell module PV installed on the roof RF is connected to a routing cable LC that serves as an electric trunk line for transmitting the electric power generated by the solar cell module PV. This routing cable LC is laid out along the ridges RD1 and RD2.

Further, the building BL is two unit groups UG1 and UG2, and the positions of the buildings RD1 and RD2 are shifted in the orthogonal direction of the buildings RD1 and RD2. In the first embodiment, even if the positions of the ridges RD1 and RD2 are displaced in this way, the routing cable LC can be continuously arranged by providing the lateral pulling portion LDS.

Further, the routing cable LC is arranged on the ridge cover 2 and the vertical cover 220 which are raised above the upper surface of the roofing material 12, and the routing cables LC are arranged in the wiring accommodating portions 30, 330. Is continuously covered by the ridge wiring blindfold covers 3 and 300. Therefore, even if the roof RF is substantially flat like a flat roof, high waterproof performance can be ensured.

Further, since the routing cable LC is covered with the ridge wiring blindfold cover 3, deterioration due to ultraviolet rays or the like can be prevented.

In addition, in the horizontal pulling portion LDS having a wide gap SP3, a water gradient is given to the vertical cover 220 that supports the pulling cable LC. Therefore, even if rainwater or the like enters the wiring accommodating portion 30b, it can be smoothly drained from the wiring accommodating portion 30b.

Further, even if the vertical cover 220 is provided with a water gradient, the upper surface of the gate-shaped portion 301 of the horizontal pulling portion wiring blindfold cover 300 is substantially horizontal. Therefore, the shape can be continuous with the ridge wiring blindfold cover 3 that covers the routing cable LC of the ridges RD1 and RD2.

Then, in the horizontal pulling portion LDS, the horizontal pulling portion wiring blindfold cover 300 is divided into a straight cover portion 310, corner cover portions 320 and 320, and joint cover portions 330 and 330. Therefore, even if the positions of the ridge RD1 and the ridge RD2 are slightly deviated due to the building BL, the distance between the straight cover portion 310 and the corner cover portions 320 and 320 is adjusted, and the joint cover portion 330 and the joint cover portion 330 are used. This can be done by adjusting the lap allowance between the straight cover portion 310 and the corner cover portion 320.

Then, the building BL includes a first unit group UG1 as a first building unit having a first roof portion RF1 including the first building RD1 and a second roof portion RF2 including the second building RD2. The second unit group UG2 as the second building portion to have is connected by shifting the position of the first building RD1 and the position of the second building RD2 in the orthogonal directions of both buildings RD1 and RD2.
Then, the routing cable LC is continuously provided in the ridge routing portions RWS and RWS arranged along the first ridge RD1 and the second ridge RD2 and the ridge allocating portions RWS and RWS. A horizontal pulling portion LDS arranged in the orthogonal direction of both buildings RD1 and RD2 is provided between the first building RD1 and the second building RD2.
Further, the ridge wiring section RWS is provided along the first ridge RD1 and the second ridge RD2, and includes a wiring base section 21 that supports the routing cable LC at a position higher than the upper surface of the roofing material 12. The wiring is arranged along the wiring accommodating portion 30 formed between the ridge cover 2 and the ridge wiring blind cover 3 covering the ridge cover 2.
The horizontal pulling portion LDS extends between the first building RD1 and the second building RD2 in the orthogonal direction of both buildings RD1 and RD2, and is provided with an upper plate portion 221 that supports the routing cable LC. The wiring is arranged along the wiring accommodating portion 30b formed between the cover 220 and the horizontal pulling portion wiring blind cover 300 that covers the vertical cover 220. The horizontal pulling portion wiring blindfold cover 300 is formed in a shape continuous with the ridge portion wiring blindfold covers 3 and 3.
Therefore, even in a building BL having a shape in which the lines of both buildings RD1 and RD2 are deviated, it is possible to continuously guide the routing cable LC and reduce the manufacturing cost and labor. Then, regardless of the shape of the ridge cover 2 and the vertical cover 220 under the routing cable LC, the horizontal pull portion wiring blind cover 300 and the ridge wiring blind cover 3 and 3 are continuous, so that the horizontal pull portion wiring blind cover 300 And the connection work of the ridge wiring blind cover 3 is easy. Further, since the horizontal pulling portion wiring blind cover 300 and the ridge wiring blind cover 3 cover the ridge cover 2 and the vertical cover 220, they are excellent in waterproofness and can prevent deterioration of the water blocking material such as the seam portion.

(2) In the wiring structure of the roof of the first embodiment, the upper plate portion 221 of the vertical cover 220 has a water gradient in the direction orthogonal to the extending direction of the horizontal pulling portion LDS (direction of arrow WG).
Therefore, even if water enters the upper plate portion 221, it can be smoothly drained from the upper plate portion 221, that is, the wiring accommodating portion 30b. In particular, in the horizontal pulling portion LDS, the space between the gap portions SP3 is wide, and the area of the upper surface of the gate-shaped portion 301 of the ridge wiring blindfold cover 3 is also wide. Therefore, there is a possibility that water staying on the upper surface of the gate-shaped portion 301 of the ridge wiring blindfold cover 3 may infiltrate, but in that case, the water can be smoothly drained to ensure high waterproofness.

(3) In the wiring structure of the roof of the first embodiment, the horizontal pulling portion wiring blind cover 300 is a ridge side portion continuous with the ridge wiring blind cover 3 and 3 of the first ridge RD1 and the second ridge RD2. Corner cover portions 320 as end cover portions forming an L shape between the 322 and the portion in the direction along the lateral pulling portion LDS (gap side portion 321) are provided at both ends in the longitudinal direction.
Therefore, the connection work with the ridge wiring blindfold covers 3 and 3 can be smoothly performed.

(4) In the wiring structure of the roof of the first embodiment, the horizontal pulling portion wiring blind cover 300 has a corner cover portion 320 as an end cover portion, an intermediate linear straight cover portion 310, and a corner cover. It is formed by connecting the joint cover portion 330 between the portion 320 and the straight cover portion 310.
Therefore, even if the distance between the first building RD1 and the second building RD2 varies depending on the building BL, the difference in the dimension of the interval is absorbed by the distance between the straight cover portion 310 and the corner cover portion 320. The lateral pulling portion LDS can be smoothly covered.
In addition, in the first embodiment, the sealing material 306 is filled between the joint cover portion 330, the straight cover portion 310, and the corner cover portions 320, 320, so that the horizontal pulling portion wiring blindfold cover 300 is provided. Even if it is divided, waterproofness can be ensured.

(5) The roof wiring structure of the first embodiment has the width of the gap SP2 formed between the solar cell modules PV in each unit group UG1 and UG2 and the gap SP3 formed in the horizontal pulling portion LDS. The width was formed to have the same dimensions. Then, in the gaps SP2 and SP3, the vertical cover 220 provided so as to cover the roofing material 12 is shared.
Therefore, the number of parts can be reduced and the manufacturing efficiency can be improved as compared with the case where the vertical cover 220 of the horizontal pulling portion LDS is separately formed independently.

The roof wiring structure of the present disclosure has been described above based on the embodiment. However, the specific configuration of the roof wiring structure of the present disclosure is not limited to these embodiments, and as long as it does not deviate from the gist of each claim of the claims, design changes or additions, etc. Is acceptable.
