A space is formed. That is, in a side view as viewed from the side wall 120 (when viewed from a direction perpendicular to the flow direction and parallel to the roof surface), as shown in FIG. The distance N between the outer corner portion at the lower end (that is, the outer end portion at the lower end of the locking portion main body 234a) U1 and the connecting fitting 101a is the length (maximum length) of the frame 220 in the solar cell module 201b. ) It is formed larger than L4. Here, the interval N is the length of a straight line (first straight line) W1 that connects the shortest distance between the corner portion U1 and the connecting fitting 101a, and the end portion U4 on the connecting fitting 101a side of the straight line W1 is connected to the connecting fitting 101a. Is located on the outer surface of the tip plate portion 152c. Since the interval N is formed larger than the length L4, the solar cell module 201a can be inserted into and removed from the gap of the interval N. Of course, the length in the thickness direction of the module main body 212 is formed to be smaller than the length L4 in the thickness direction of the frame 220, and the thickness L7 of the substantially U-shaped section in the support portion 230 (the upper end of the upper surface portion 232b and The length in the vertical direction between the lower surfaces 231-1 of the support body 231 is smaller.

It is preferable to be located on the side of the ridge. By doing so, the length L4 in the thickness direction of the frame 220 can be made as close to the length of the interval N as possible, and as a result, the interval N is made as small as possible to increase the efficiency of installation space for the solar cell module. Can be achieved.

  In addition, as described above, the ridge side end of the solar cell module 201a is provided between the long side portion 222a of the frame 220 of the solar cell module 201b and the connection fitting 101a and between the connection fitting 101b and the connection fitting 101a. A gap for insertion and removal is formed, and the ridge side end of the solar cell module 201a is located between the solar cell module 201b on the ridge side, the connecting metal fitting 101b and the roof tile 1d, and the connecting metal fitting 101a on the eaves side. A space for arranging the is formed. In particular, the end on the head side of the roof tile 1d on the ridge side is substantially in the same position in the flow direction as the end on the eave side of the connecting fitting 101b (strictly speaking, the head side of the roof tile 1d on the ridge side) The end of the connecting metal fitting 101b is located on the ridge side in the flow direction with respect to the eaves side edge of the connecting metal 101b), and also in that respect, the solar cell module 201b on the ridge side, the connecting metal fitting 101b and the roof tile 1d, A space for arranging the ridge-side end of the solar cell module 201a can be secured between the eaves-side coupling fitting 101a.

  Moreover, since the space S2 is provided, when rotating the eaves side of the solar cell module 201a downward, it is possible to sufficiently provide a space for arranging the ridge side end of the solar cell module 201a, The metal fitting locking part 234 does not hinder.

  The long side portion 222a and the long side portion 222b have the same configuration except that they are symmetric in the front-rear direction, and the short side portion 224a and the short side portion 224b have the same configuration except that they are symmetric.

  In the above description, the straight lines W1, W2, and W3 may be considered as virtual planes.

  A construction method of the mounting structure P having the above configuration will be described with reference to FIGS. First, the roof tile 1 is constructed on the roof surface. Here, on the roof surface, a plurality of piers 310 are fixed to the upper surface of a base plate 300 as a base material. In other words, the crosspiece 310 is provided in the girder direction and provided in the flow direction with an interval. Note that the roof tile 1 may be directly constructed on the field board 300 by omitting the configuration of the pier 310.

  It is assumed that a nail is inserted into the nail holes 60a and 60b of the roof tile 1 and hit against the pier 310a to construct an arbitrary roof tile 1a (see FIG. 12). Thereafter, the crosspiece 40 of the roof tile 1b to be constructed adjacent to the left side of the roof tile 1a is put on the insertion portion 30 of the roof tile 1a, and the nail is inserted into the nail holes 60a and 60b of the roof tile 1b, and the crosspiece 310a. The roof tile 1b is constructed by hitting it. The above steps are repeated to construct the roof tile 1 in the girder direction. In the above description, the roof tile is sequentially constructed on the left side of the constructed roof tile. However, the roof tile may be constructed in the opposite direction, and the roof tile 1 constructed on the right side of the constructed roof tile 1 may be used. The roof tiles may be sequentially constructed so that the insertion part 30 is inserted into the crosspiece 40 of the roof tile 1 that has already been constructed.

  Next, when constructing the roof tile 1 to be constructed on the bottom side of the constructed roof tile 1, the construction is performed by engaging the latching protrusion 58 with the latched portion 36 of the insertion portion 30 of the roof tile 1. I will do it. For example, when the roof tile 1c in FIG. 12 is constructed, the locked portion 36 is locked to the locking protrusion 58 of the roof tile 1a located obliquely at the lower left, and the nail holes 60a and 60b are inserted into the pier 310b. The nails are driven in and installed. Then, the roof tile 1d is constructed adjacent to the left side of the roof tile 1c. That is, the locked portion 36 of the roof tile 1d is locked to the locking protrusion 58 of the roof tile 1b located obliquely at the lower left, and the crosspiece 40 of the roof tile 1d is covered with the insertion portion 30 of the roof tile 1c. The nails are inserted into the nail holes 60a and 60b of the roof tile 1d, and the nail is driven into the pier 310b. The above steps are repeated to construct roof tiles in the direction of the roof tile 1c. Similarly to the above, a roof tile may be constructed on the right side of the constructed roof tile.

  As described above, the construction of the roof tile 1 in the girder direction is sequentially performed from the eave side (R1 side in FIG. 12) to the ridge side (R2 side in FIG. 12) in the flow direction, and the roof tile as shown in FIG. 1 is constructed.

  Next, the connecting metal fitting 101 is attached to each roof tile 1 constructed on the roof surface. That is, the front side of the connecting metal fitting 101 is the head 14 side of the roof tile 1, and the locking projection 16 is inserted into the opening 112 a of the connecting metal fitting 101, and the tip end portion 114 b of the tongue-like elastic part 114 and the tongue piece-like shape are inserted. In a state where the tip 116b of the elastic portion 116 is in contact with the upper surface of the roof tile 1, the connecting metal fitting 101 is pressed against the roof tile 1 side, and the bottom plate portion 111 is formed between the upper surface portion 18a of the protruding portion 18 and the protruding portion 20. By setting the state in contact with the upper surface portion 20a, the tongue-like elastic portions 114 and 116 are rotated upward to be in the state shown in FIG. In other words, the tongue-like elastic portion 114 is projected upward from the opening 112b, and the tongue-like elastic portion 116 is projected upward from the opening 112c. In this state, the tip portion 114b is on the back side of the groove portion 18f, and the tip portion 116b is on the back side of the groove portion 20f.

  Thereafter, the connecting metal fitting 101 is slid to the head side of the roof tile 1 so that the edge 113 on the back side of the opening 112a enters the notch 16f of the locking projection 16 and is shown in FIG. 13 (b). It becomes a state.

  Thereafter, the connecting metal fitting 101 is further slid to the head side of the roof tile 1 so that the tip end portion 114b of the tongue-like elastic portion 114 is fitted into the groove portion 18f and the tip end portion 116b of the tongue-like elastic portion 116 is fitted. Is fitted into the groove 20f, resulting in a state shown in FIG.

  In the state in which the tip end portion 114b is fitted in the groove portion 18f and the tip end portion 116b is fitted in the groove portion 20f, the edge portion 113 on the back side of the opening portion 112a is connected to the back portion (the end portion on the front side) of the notch portion 16f. ) And the bottom plate portion 111 is locked to the locking protrusion 16. As described above, the connecting metal fitting 101 is attached to the roof tile 1 by being locked and fixed to the roof tile 1. Here, “locking / fixing” means that, as shown in FIG. 13B, after the edge 113 of the coupling fitting 101 is locked to the locking projection 16, the tip 114b is fitted into the groove 18f. At the same time, the fitting portion 101 is fixed to the roof tile 1 by fitting the front end portion 116b into the groove portion 20f. In a state where the connecting metal fitting 101 is attached to the roof tile 1, the state shown in FIGS.

  In addition, in the state which attached the connection metal fitting 101 to the roof tile 1, as shown in FIG.13 (c), the edge part of the front side (eave side) of the connection metal fitting 101 and the front side (eave side) of the roof tile 1 are shown. The end portion is at substantially the same position in the flow direction.

  When attaching the connecting metal fitting 101, it may be attached to a predetermined roof tile 1 so that two connecting metal fittings 101 are attached to one solar cell module 201, but the connecting metal fitting 101 engaged with the solar cell module 201 is attached. It is preferable to attach the connecting metal fittings 101 to all the roof tiles 1 in order to increase the number of the roof tiles and to reliably perform the construction on the roof surface.

  Next, the solar cell module 201 is attached to the connecting metal fitting 101 attached to the roof tile 1. In the solar cell module 201, either the long side portion 222a or the long side portion 222b may be the eaves side, but the long side portion 222a side is set as the eave side, and the long side portion 222b is attached as the ridge side. . In FIG. 17 and FIG. 18, the solar cell module to be attached is a solar cell module 201a, the solar cell module installed on the ridge side of the solar cell module 201a to be attached is a solar cell module 201b, and the solar cell module The connecting bracket to which 201a is attached is referred to as a connecting bracket 101a, and the connecting bracket to which the solar cell module 201b is attached is referred to as a connecting bracket 101b.

  First, the solar cell module 201a is in a state where the eave side (long side portion 222a side) is lifted upward relative to the ridge side (long side portion 222b side) with respect to the original installation direction of the solar cell module 201a. The ridge side of the module 201a is inserted obliquely from above into the gap between the connection fitting 101a (connection fitting for attaching the solar cell module 201) and the solar cell module 201b provided adjacent to the ridge side, and the state shown in FIG. To do. In addition, since the roof surface is inclined, it is difficult for the installer to stand and work on the wing side of the solar cell module to be installed. Become.

  Thereafter, the eaves side of the solar cell module 201a is rotated downward and is slightly slid to the eaves side, so that the claw portions 234b of the metal fitting locking portion 234 of the long side portion 222b as shown in FIG. Is locked to the locking portion 154 of the connecting metal fitting 101a. When the claw portion 234b of the metal fitting engaging portion 234 of the long side portion 222b is engaged with the engaging portion 154 of the connecting metal fitting 101a, in this state, another wiring cord connector (for example, the adjacent solar cell module 201) is used. The connector 216a) of the wiring cord 216 is connected.

  Then, as shown in FIG.18 (b), the eaves side of the solar cell module 201a is rotated further below. That is, the solar cell module 201a is rotated downward around the engaging portion of the claw portion 234b and the locking portion 154. In addition, since the roof tile 1 and the connecting metal fitting 101a are inclined on the roof surface, when the solar cell module 201a is rotated downward, the solar cell module 201a is also inclined toward the eaves side, and the solar cell module 201a. The engagement between the locking portion 154 and the claw portion 234b is strengthened by its own weight.

  Thereafter, as shown in FIG. 18 (c), the claw portion 234b of the metal fitting locking portion 234 of the long side portion 222a contacts the front end plate portion 142c of the side wall portion 140, so that the eave side of the solar cell module 201a is pushed downward. Then, the claw portion 234b is guided by the outer surface of the tip plate portion 142c and slides downward.

  Thereafter, the claw portion 234b of the metal fitting engaging portion 234 of the long side portion 222a is engaged with the engaging portion 144, and the state shown in FIG.

  As described above, the solar cell module 201 is locked to and fixed to the connecting metal fitting 101 to be attached to the connecting metal fitting 101, and the solar cell module 201 is supported by the connecting metal fitting 101. Here, “locking / fixing” means that the claw portion 234b of the long side portion 222a is locked after the claw portion 234b of the long side portion 222b is locked to the locking portion 154, as shown in FIG. Means that the solar cell module 201 is fixed to the connection fitting 101 by being locked to the locking portion 144. In a state where the solar cell module 201 is attached to the connecting metal fitting 101, the state shown in FIG. 18 (d), FIG. 19, and FIG. 20 is obtained.

  In FIG. 15 and FIG. 16, the roof tile 1a and the connecting metal fitting 101a are actually arranged in the beam direction (rightward as viewed from the eaves side) with respect to the roof tile 1b and the connecting metal fitting 101b as shown in FIG. 17-19, the cutting line for the roof tile 1a and the connecting fitting 101a and the cutting line for the roof tile 1b and the connecting fitting 101b are shifted in the digit direction. That is, FIGS. 18 and 19 are CC cross-sectional views in FIG. 20, and FIG. 17 is a cross-sectional view of main parts in the CC cross-section.

  When the solar cell module 201 to be installed on the ridge side is attached, the solar cell modules 201 are sequentially attached to the eaves side solar cell modules 201, and the two rows of solar cell modules 201 and the two rows of solar cell modules 201 are attached. The state where one solar cell module 201 adjacent to the eaves side is constructed is as shown in FIG.

  As described above, since the solar cell module 201 can be attached to the connecting metal fitting 101 in a state where the solar cell module 201 is installed adjacent to the building side, the solar cell module 201 can be sequentially applied from the building side. Even when the installer works while standing on the eave side of the solar cell module to be attached, the installer does not step on the solar cell module 201 with his / her legs. That is, when the solar cell module 201 must be constructed from the eaves side, it is necessary for the installer to construct the solar cell module 201 on the solar cell module 201 that has already been constructed. Therefore, it is not necessary to ride on the solar cell module 201 for installation.

  Further, the lower end portion 144a of the locking portion 144 and the lower end portion 154a of the locking portion 154 are formed so as to be lower from the proximal end side toward the distal end side, and in the side view, the direction of the upper surface of the bottom plate portion 111 In the claw portion 234b of the solar cell module 201, the first surface portion 234b-1 has an acute angle with respect to the inner surface of the locking portion main body 234a (the horizontal direction). Since the angle γ) is formed, the engagement between the locking portions 144 and 154 and the claw portion 234b can be ensured. Note that the angle γ formed by the first surface portion 234b-1 with respect to the inner surface of the locking portion main body 234a may be a right angle. In this case, the angles β3 and β13 form acute angles. As a result, the engagement between the claw portions 234b can be ensured.

  Note that a jig 301 shown in FIG. 21 is used to remove the solar cell module 201 attached to the connection fitting 101.

  That is, the jig 301 is formed of a single metal plate-like member, and has an elongated rectangular handle portion 310 and a tip portion 320 connected to the tip of the handle portion 310, and the tip portion 320. Is formed wider than the handle portion 310. That is, the side portion on the right side surface of the tip portion 320 is formed in a straight line continuous with the side portion on the right side surface of the handle portion 310, and the left side surface side of the tip portion 320 protrudes to the left side surface side from the handle portion 310. Yes.

  The distal end portion 320 has a substantially square shape, and a notch portion 330 is formed from a side portion on the left side surface side. The notch 330 has a substantially square shape, and includes straight side portions 330a and 330d that are parallel to each other, a straight side portion 330c that is formed at right angles to the side portion 330d, and a side portion 330a. On the other hand, it has an angle t greater than 180 degrees and a shape having a side portion 330b that forms an acute angle with respect to the side portion 330c. In other words, the distal end portion 320 is formed by forming two projecting portions 342 and 344 on one side portion of a substantially rectangular base end portion 340 connected to the distal end side of the handle portion 310 with a gap therebetween. A notch 330 surrounded by the base end portion 340 and the projecting portions 342 and 344 is formed.

  That is, the protruding portion (first protruding portion) 344 is inclined obliquely with respect to the side portion 330b, the side portion 330a, the linear side portion 344a substantially parallel to the side portion 330c, and the side portion 344a. It has a shape surrounded on three sides by a straight side 344b and a straight side 344c substantially parallel to the side 330a. That is, an inclined side portion 344b is formed at the outer corner of the tip of the protrusion 344, and the corner is chamfered so that the protrusion 342 can be easily placed in the recess 121-2 of the connecting metal fitting 101. It has a shape.

  The protruding portion (second protruding portion) 342 includes a side portion 330d, a linear side portion 342a that is substantially parallel to the side portion 330c, a substantially arc-shaped side portion 342b, and a side portion 330d that is substantially parallel to the side portion 330d. It has a shape surrounded on three sides by a straight side portion 342c.

  The jig 301 can be said to have a configuration in which two projecting portions 342 and 344 are formed on one side portion in the longitudinal direction of an elongated rectangular plate-like member with an interval between the two projecting portions 342 and 344. A notch 330 is formed at the top.

  In the distal end portion 320, the base end portion 340 is formed by being slightly bent via a broken line 350 on the extension line of the side portion 330d, and is bent so that a portion on the distal end side is obliquely upward from the broken line 350. doing. That is, as for the front-end | tip part 320, the front end side becomes the 1st area | region 320-1 via the broken line 350, and a base end side becomes the 2nd area | region 320-2. That is, the first region 320-1 is configured by the region on the distal end side of the base end portion 340 and the protruding portion 344, and the second region 320-2 is protruded from the region on the rear end side of the base end portion 340. Part 342. As shown in FIG. 19, when the solar cell modules 201a and 201b are provided adjacent to each other in the flow direction, and the solar cell module 201b is a removal target solar cell module, the removal target solar cell module 201b The lower end of the metal fitting locking portion 234 of the long side portion 222a on the eave side and the upper end of the long side portion 222b on the ridge side of the solar cell module 201a adjacent to the eave side are heights perpendicular to the flow direction. Since the positions are substantially the same in the direction, the jig 301 can be easily operated by bending at the position of the broken line 350. That is, even when the protruding portion 344 is disposed in the recess 121-2, the first region 320-1 can be easily inserted from the gap between the solar cell module 201a and the solar cell module 201b, and the jig 301 is illustrated in FIG. 22, when the first region 320-1 is made parallel to the flow direction in the state of being engaged with the connecting fitting 101, the second region 320-2, which is a part on the base end side with respect to the broken line 350, is flow direction. (That is, the base end side of the second region 320-2 is inclined upward), so that the second region 320-2 is moved from the gap between the solar cell module 210a and the solar cell module 201b to the solar cell module. The jig 301 can be guided to the upper side of the 201 a, and the jig 301 can be operated in a state where the grip portion 310 is gripped.

  The notch 330 is formed in a state in which the protruding portion 344 is disposed horizontally in the recess 121-2 of the connecting metal 101, and the side 330b of the notch 330 is in contact with the side 121c of the side plate 121 of the connecting metal 101. By turning the base end side of the jig 301 to the right in a plan view (that is, rotating to the left side) around the contact position of the side portion 330b and the side portion 121c, the corner portion on the inner side of the protruding portion 342 is obtained. 342-1 is in contact with the side plate portion 142.

  When the engagement of the locking portion 144 of the connecting metal fitting 101 and the claw portion 234b of the solar cell module 201 is released by the jig 301 having the above-described configuration, the protruding portion 344 is attached to the connecting metal fitting 101 as shown in FIG. It arrange | positions horizontally in the recessed part 121-2. At this time, since the inclined plate portion 124 is formed to be inclined downward toward the front side, the protruding portion 344 is protruded by sliding along the upper surface of the inclined plate portion 124 from the upper surface of the band-shaped portion 122. The shaped portion 344 can be easily disposed in the recess 121-2. Moreover, since the jig | tool 301 is bent via the broken line 350, the 1st area | region 320-1 is inserted from the clearance gap between the adjacent solar cell modules 201, and the protrusion part 344 is arrange | positioned in the recessed part 121-2. be able to.

  When the projecting portion 344 is disposed in the recess 121-2, the side portion 330b of the notch portion 330 is brought into contact with the side portion 121c of the side plate portion 121 of the connection fitting 101, and the contact position between the side portion 330b and the side portion 121c is determined. As a center, the base end side of the jig 301 is rotated to the right (that is, rotated to the left side) in plan view so that the corner portion 342-1 inside the protruding portion 342 contacts the side plate portion 142. . Thereafter, in a state where the corner portion 342-1 is in contact with the side plate portion 142, the handle portion 310 is further rotated to the left side, whereby the side plate portion 142 is pushed to the back side, and the locking portion 144 and the solar cell module 201 are moved. The engagement of the claw portion 234b can be released. Note that FIG. 22 is drawn with the solar cell module 201 omitted for ease of explanation. In practice, the jig 301 is naturally attached with the solar cell module 201 attached to the connection fitting 101. Perform the above operation.

  Note that the locking portion 144 and the claw portion are formed by rotating the jig 301 left and right so that the side portion 330b is in contact with the side portion (vertical side portion) 131c of the side wall portion 130 of the connecting metal fitting 101 by making the jig 301 symmetrical. The engagement of 234b may be released. That is, the protruding portion 344 is disposed laterally in a recess (a notch portion for jig placement) 131-2 (a recess corresponding to the recess 121-2 in the side wall portion 130) of the connecting metal fitting 101, and a side portion of the notch portion 330 is disposed. The jig 301 is centered on the contact position of the side portion 330b and the side portion 131c in a state where the 330b is in contact with the side portion 131c (the side portion corresponding to the side portion 121c of the side wall portion 130) of the side plate portion 131 of the connecting metal fitting 101. When the base end side of the projection 342 is rotated counterclockwise (that is, rotated to the right side), the corner portion 342-1 on the inner side of the protruding portion 342 contacts the side plate portion 142, and further the handle portion 310 is rotated to the right side. By moving, the side plate part 142 is pushed to the back side, and the engagement between the locking part 144 and the claw part 234b of the solar cell module 201 can be released.

  Therefore, in the state shown in FIG. 18D, in order to remove the solar cell module 201a from the connection fitting 101a, the jig 301 is used to connect the eaves side claw portion 234b of the solar cell module 201a and the connection fitting 101a. The engagement with the stop portion 144 is released, and thereafter, the solar cell module 201a may be removed in the reverse procedure. That is, after releasing the engagement between the claw portion 234b and the locking portion 144, as shown in the order of FIGS. 18C, 18B, and 18A, the eaves side of the solar cell module 201a is rotated upward, If it will be in the state shown in FIG. 17, even if there exists an adjacent solar cell module by the side of a ridge by pulling out the solar cell module 201a diagonally upward, a solar cell module can be removed easily.

  The connection fitting 101 and the jig 301 constitute a connection fitting set for installing a solar cell module.

  According to the solar cell module 201 and the connecting bracket 101 in the mounting structure P, the bracket locking portion 234 is formed at a position retracted in the lateral direction from the support portion 230, so that the space S1 is formed. When the solar cell module 201a is attached, the metal fitting locking portion 234 may become an obstacle when the solar cell module 201a is inserted / removed between the solar cell module 201b on the ridge side and the connecting metal fitting 101a on the eave side from above. Absent.

  Further, a space S2 is formed between the lower end of the metal fitting locking portion 234 and the lower end on the front side of the connecting metal fitting 101, so that a space S2 is formed, and the corner portion U3 is inward of the straight line W2 in a side view. Therefore, between the solar cell module 201b and the connecting metal fitting 101b and the eave-side connecting metal fitting 101a, a gap for inserting and removing the ridge side end of the solar cell module 201a and the ridge side end of the solar cell module 201a are provided. Since the space to be arranged can be formed and the space S2 is provided and does not hinder the rotation of the solar cell module 201a, it is attached to the roof tile constructed on the inclined roof. In the solar cell module to be attached to the connecting bracket, even when there is a solar cell module adjacent to the eaves side, it can be easily removed from the connecting bracket and the roof is inclined. In construction, it is possible to sequentially construction toward the eaves side from the ridge side.

  Further, according to the jig 301, the solar cell module 201 can be easily detached from the connection fitting 101.

  In addition, since the connecting metal fitting 101 is provided with the inclined plate portion 124 for guiding the protruding portion 344 of the jig 301 to the recessed portion 121-2, the protruding portion 344 can be easily disposed in the recessed portion 121-2. can do.

  In addition, in the latching | locking part 232 of the flame | frame 220 of the solar cell module 201, it is good also as a structure which abbreviate | omitted the structure of the protrusion part 233, as shown in FIG. That is, in that case, the support part 230 has a substantially strip-shaped support part main body 231 and a substantially bowl-shaped cross section (substantially L-shaped cross section) formed to protrude upward from the outer end of the support part main body 231. Or the locking portion 232 of the plate-like portion 234a-1, and does not protrude from the outer surface of the plate-like portion 234a-1.

  Also in the configuration shown in FIG. 23, the outer end in the lateral direction (that is, the outer end of the plate-like portion 234 a-1) that is the direction along the bottom surface of the module main body 212 in the metal fitting locking portion 234 is supported.
