  Hereinafter, each structural member of the roof structure 1 of 1st Embodiment of this invention is demonstrated.

First, the roof member 202 will be described.
The roof member 202 is formed by processing a metal such as copper, stainless steel, aluminum, steel, or a color stainless steel, a color aluminum, a fluorine steel plate, a galvalume steel plate, a color iron plate, or the like obtained by surface-treating an appropriate one of these metals. It is a substantially rectangular thin plate-like roof material formed. As shown in FIG. 3, a hook piece 212 is formed at one end of the roof member 202 in the short direction 1, and the other end in the short direction l is slightly closer to the center. A latching protrusion 213 is formed.

  The latching piece 212 is a portion called a so-called gavel, which is formed by bending an end portion of the roof member 202 in the short direction 1 to the back surface side. More specifically, the hooking piece 212 is formed by bending an end portion located on the eaves side (front side in the short direction 1 in FIG. 3) when the roof member 202 is attached to the roof base. The cross-sectional shape is substantially “V” and extends in the longitudinal direction w.

  The latching protrusion 213 is a part formed by bending a part of the metal plate so as to be convex on the surface side. That is, the latching protrusion 213 includes two projecting wall portions 213a and 213b that are erected so as to project in the direction from the back surface side to the front surface side (upward in the height direction) in the front and back direction of the roof member 202, It is formed by the end surface formation part 213c which forms a protrusion end surface between the two protrusion wall parts 213a and 213b.

Each of the two protruding wall portions 213a and 213b protrudes slightly inclined with respect to the front and back direction (height direction) of the roof member 202, and more specifically, both of the latching pieces 212 are located. Inclining and projecting toward the end side (the front side in the short direction 1 in FIG. 3). Here, the protruding wall portion 213b formed at a position close to the end portion where the latching piece 212 is located and the other protruding wall portion 213a have different inclination angles and are formed at a position close to the latching piece 212. The projecting wall portion 213b is inclined at a steeper angle than the other projecting wall portions 213a.
And the roof material latching space 214 is formed between the protruding wall part 213b formed in the position close | similar to the latching piece 212, and the part which follows the lower end part of this protruding wall part 213b. The roof material latching space 214 is a space having a triangular cross-sectional shape and extending in the longitudinal direction w of the roof member 202.

The end surface forming portion 213c is a substantially rectangular flat plate portion, and is continuous with the upper end portions of the two protruding wall portions 213a and 213b at both ends in the lateral direction l. The end surface forming portion 213c is substantially parallel to a portion adjacent to the latching protrusion 213 of the roof member 202, that is, a portion continuous with the lower end portions of the protruding wall portions 213a and 213b, and a position separated in the front and back direction of the roof member 202. It has become.
The above is the description of the roof member 202.

Next, the solar cell panel 2 will be described.
The solar cell panel 2 is usually used by attaching members such as a terminal box, a cable, and a heat insulation reinforcing material (not shown) to the solar cell panel itself. In addition, although the kind of solar cell panel 2 is not specifically limited, In this embodiment, what is called a frameless solar cell panel which does not use what is called a frame is employ | adopted.
Moreover, the external appearance of the solar cell panel 2 is a rectangular plate-like body as shown in FIG.

Subsequently, the rail member 3 will be described.
The rail member 3 is a member that supports the fixing member 5 when the fixing member 5 is fixed to the roof member 202 as shown in FIGS. The rail member 3 is a long rod-shaped body as shown in FIG. 5 and has a cross-sectional shape of “U”. That is, the rail member 3 has a rectangular flat plate-shaped mounting surface 16 and wall portions 17 and 18 bent substantially vertically downward from both ends of the mounting surface 16 in the width direction w. A space 19 sandwiched between the wall portions 17 and 18 is formed below the placement surface 16 as shown in FIG. The space 19 represents a space in which a part or all of the locking piece 56 can be stored, and includes not only a closed space but also an open space opened in the insertion direction of the locking piece 56 of the base portion 21 of the fixing member 5. Including.

  As shown in FIG. 5, the mounting surface 16 of the rail member 3 is provided with a connecting screw hole 60, an engaging hole 6, and a connecting through hole 61 in order from the front end side to the rear end side in the longitudinal direction l. ing.

  The connecting screw hole 60 is a through-hole having a circular shape that is formed in a portion slightly behind the front end portion of the placement surface 16 and penetrates the placement surface 16 in the front-back direction.

  The engagement hole 6 has a slit shape extending along the longitudinal direction, and is a hole that penetrates the mounting surface 16 in the member thickness direction. Further, the engagement hole 6 is provided over most of the rail member 3 in the longitudinal direction l. The opening width W1 of the engagement hole 6 is smaller than the distance W2 between the wall portions 17 and 18, as shown in FIG.

  The connection through hole 61 is a long hole provided in the vicinity of the rear end of the rail member 3 as shown in FIG. The length of the connecting through hole 61 in the longitudinal direction 1 is shorter than the length of the engaging hole 6 in the longitudinal direction 1.

The rail member 3 has a fixture 7 that can slide along the engagement hole 6.
The fixture 7 is formed of a fixing bolt 8 and a positioning nut 10 as shown in FIGS.
Specifically, the fixing bolt 8 is a square bolt, and the head 11 is a square-shaped bolt. The width of the head portion 11 is smaller than the distance W2 between the wall portions 17 and 18, and larger than the opening width W1 of the engagement hole 6. The fixing bolt 8 is paired with a positioning nut 10. When assembled as shown in FIG. 5, the shaft portion 12 of the fixing bolt 8 is exposed from the engagement hole 6.

  The positioning nut 10 is a flat plate-like member as shown in FIG. 5 and has a substantially “U” shape in plan view. That is, the positioning nut 10 has a notch 15 that can be engaged with the shaft 12 of the fixing bolt 8.

  When the eyes are moved to the wall portions 17 and 18, the distance between the two wall portions 17 and 18 becomes narrower toward the rear in the longitudinal direction l. That is, the two wall portions 17 and 18 are slightly inclined in the front-rear direction l and are extended in a direction approaching each other. From this, the rail member 3 becomes narrower in the width direction w from the front side in the longitudinal direction l toward the rear side. In other words, the rail member 3 has a rear end side that is thinner than the front end side.

  Each of the wall portions 17 and 18 includes a latch piece connecting portion 62 positioned on the front end side and a side wall portion main body 63 positioned behind the latch piece connecting portion 62. At this time, the length in the height direction of the side wall portion main body 63 increases from the front to the rear in the longitudinal direction l. At this time, comparing the length in the height direction of the latching piece connecting portion 62 and the length of the front end portion of the side wall portion main body 63 which is the shortest length in the side wall portion main body 63, The length in the height direction of the latch piece connecting portion 62 is longer than the length of the front end portion of the side wall portion main body 63.

  Here, paying attention to the lower part on the front end side of the rail member 3 in FIG. 5, the rail connecting piece 64 is provided in a portion located outside the wall portions 17 and 18.

The rail connecting piece 64 has a rectangular flat plate shape, and is substantially perpendicular to the latching piece connecting portion 62 at the front portion of the inner side surface (the side surface on the side of the walls 17 and 18). Here, the length of the rail connection piece 64 in the front-rear direction (longitudinal direction 1 of the rail member 3) is longer than the length of the hook piece connection part 62 in the front-rear direction. Therefore, the inner side surface of the rail connection piece 64 is continuous with the wall portions 17 and 18 (the latching piece connection portion 62) only at the front portion, and is not in contact with the wall portions 17 and 18 at the rear portion.
The above is the description of the rail member 3.

Next, the fixing member 5 which is a feature of the present invention will be described.
As shown in FIGS. 1 and 7, the fixing member 5 is formed of a holding portion 20 that holds one side of the solar cell panel 2 and a base portion 21 that is fixed to the rail member 3. The fixing member 5 is fixed to the rail member 3 through the base portion 21, and the holding portion 20 engages with one side of the solar cell panel 2, thereby fixing the solar cell panel 2 to the roof.

As shown in FIG. 8, the holding portion 20 has a substantially “e” shape when viewed from the front, and is a member extending in the left-right direction w.
The length of the holding part 20 in the longitudinal direction w is longer than the length of the base part 21 in the width direction w as shown in FIG. Specifically, the length of the holding portion 20 in the longitudinal direction w is about twice the length of the base portion 21 in the width direction w. That is, when assembled as shown in FIG. 7, the holding portion 20 protrudes outward from the base portion 21.

Here, as shown in FIG. 27, the folding position of the attachment small piece portion 242 and the bending position of the attachment large piece portion 243 are different in the height direction. Specifically, the two attachment small piece portions 242 It is bent above the attachment large piece 243.

As shown in FIGS. 25 and 27, the attachment small piece portion 242 is a substantially rectangular plate-like portion that protrudes forward at a slightly upper portion from the lower end of the module holding metal fitting 218. The attachment small piece portion 242 is formed with a metal fitting screw hole 245 penetrating from the top surface to the bottom surface of the attachment small piece portion 242.
The screw hole 245 for metal fittings is a through-hole having a circular opening shape, and opens at the center of the top and bottom surfaces of the mounting small piece portion 242 and extends along the height direction (vertical direction) of the mounting small piece portion 242. . In other words, the metal fitting screw hole 245 is a through-hole penetrating the central portion of the attachment small piece portion 242.

  As shown in FIGS. 26 and 27, the attachment large piece 243 is a substantially rectangular plate-like portion that protrudes rearward from the lower end portion of the module holding metal fitting 218. The attachment large piece portion 243 faces the holding side top plate portion 240 in the height direction, and the lengths in the longitudinal direction w and the short direction l are shorter than the holding side top plate portion 240.

Here, as shown in FIGS. 25 and 26, two bead portions 244 are provided at predetermined intervals in the vicinity of the center of the module holding metal 218 in the longitudinal direction w. All of these bead portions 244 extend from the attachment large piece portion 243 to the holding side top plate portion 240 via the holding side wall portion 241.
Further, when attention is paid to both end portions in the longitudinal direction w of the holding-side top plate portion 240, as shown in FIG. 25, bead portions 246 are respectively provided at portions slightly from the center from the end portions in the longitudinal direction w. Yes. Each of these bead portions 246 extends forward from the rear end of the holding side top plate portion 240 to the vicinity of the center of the holding side top plate portion 240 in the front-rear direction l.
These bead portions 244 and bead portions 246 are provided in order to improve the rigidity of the eaves tip mounting bracket 200.

  Next, the assembly structure of the eaves mounting bracket 200 will be described. As shown in FIG. 20, the eaves mounting bracket 200 is formed by integrally mounting the eaves mounting bracket body 217 and the module holding bracket 218. When attaching the eaves-end fitting main body 217 and the module holding fitting 218, as shown in FIG. 21 and FIG. 28, the module holding fitting 218 is inserted into the fitting attachment through-hole 235 formed in the upper plate portion 226 of the eaves-end fitting main body 217. It is assumed that the lower part of is fitted.

At this time, as shown in FIG. 28 (b), the upper surface of the mounting large piece portion 243 of the module holding metal fitting 218 is in contact with the bottom surface of the upper plate portion 226 of the eaves-end metal fitting body 217 from below.
Further, the holding-side side wall portion 241 of the module holding metal fitting 218 and the accessory plate portion 234 of the eaves-end metal fitting main body 217 are in surface contact with each other in the front-rear direction l (left-right direction in FIG. 28). Specifically, the holding side wall portion 241 and the accessory plate portion 234 are erected in parallel in a state where a part of the rear side surface of the holding side wall portion 241 and the front side surface of the accessory plate portion 234 are in contact with each other. It is in a state.
Then, as shown in FIGS. 28B and 28C, the attachment small piece portion 242 of the module holding metal fitting 218 is in contact with the upper plate portion 226 of the eaves-end metal fitting 217 from above. At this time, there are metal screw holes 245 (see FIG. 25) formed in the respective mounting piece portions 242 and metal screw holes 236 (see FIG. 21) formed in the upper plate portion 226 of the eaves-end metal body 217. The overlapped state (see FIG. 28C) is obtained. That is, the metal fitting screw hole 245 of the module holding metal fitting 218 and the metal fitting screw hole 236 of the eaves-end metal fitting body 217 are overlapped to form an integral communication hole.

Then, a fastening element 238 such as a screw is inserted through the metal fitting screw hole 245 of the module holding metal fitting 218 and the metal fitting screw hole 236 of the eave metal fitting main body 217 so that the module holding metal fitting 218 and the eave metal fitting main body 217 are integrated. To fix.
Here, the fastening element is a superordinate concept such as a screw, a nail, or a screw.

  When the eaves mounting bracket 200 is assembled in this way, as shown in FIGS. 28 (b), 28 (c), and 29, below the holding side top plate 240, which is a part of the module holding bracket 218. A module holding recess 219 is formed which is a space surrounded by the holding side top plate 240, the holding side wall 241 and the upper plate 226 of the eaves-end bracket body 217.

As shown in FIG. 29, the module holding recess 219 is a space having a substantially rectangular cross section and extending along the left-right direction w (the direction perpendicular to the front-rear direction and the up-down direction) of the eaves mounting bracket 200 and having the open rear side. is there. In other words, the module holding recess 219 is formed in a groove shape on the upper plate portion 226.
Here, as shown in FIGS. 28 (c) and 29, the module holding recess 219 and the space 231 located below the engaging portion 230 are positioned so as to overlap with each other in the height direction of the eaves tip mounting bracket 200. ing. And the front-end part of the module holding | maintenance recessed part 219 and the front-end part of this space 231 are the same positions in the front-back direction 1 (left-right direction in FIG. 28).
The module holding recess 219 is provided with a protective member (not shown) made of an elastic body such as rubber. Thus, when the solar cell panel 2 is fitted, the fitted portion of the solar cell panel 2 is not damaged, and the fitted solar cell panel 2 is not shaken.
The above is the description of the eaves mounting bracket 200.

  Then, the positional relationship of the roof structure 1 is demonstrated along the general construction procedure of the roof structure 1 of this embodiment.

In order to construct the roof structure 1 of the present embodiment, the first roof base is formed, and the roof members 202 are arranged in a matrix on the roof base 202 and placed with a planar spread. And when installing this roof member 202, the eaves-end fitting 200 and the rail member 3 are attached integrally.
And the solar cell panel 2 is installed on the roof by the eaves-end fitting 200, the fixing member 5 attached to the rail member 3, and the connecting piece 100.
That is, in this embodiment, the foundation roof structure 203 is constructed prior to the installation of the solar cell panel 2.

The specific procedure is as follows.
First, as a first step, as shown in FIG. 30, a plurality of eaves mounting brackets 200 are attached to the eaves of the roof base with a predetermined interval. At this time, the eaves side front end surface 268a of the base plate 268 and the front side surface of the front standing wall portion 225 which is a part of the eaves end fitting 200 are installed so as to form the same plane. Then, a fastening element 271 such as a wood screw is inserted into the fixing screw hole 229 (see FIG. 23) of the eaves attaching bracket 200, and the eaves attaching bracket 200 is fixed integrally with the roof base.

  Next, as a second step, as shown in FIG. 31, the roof member 202a in the first row of eaves side is attached on the roof base. At this time, as shown in FIG. 32A, a space 272 (engagement region) formed between the upper plate portion 226 and the lower plate portion 224 of the eaves-end fitting 200 with the hook piece 212 of the roof member 202a. ). Then, the latching piece 212 of the roof member 202a is further moved to the eaves side (the front side and the right side in FIG. 32) to get over the engaging portion 230, and then the latching piece 212 of the roof member 202a is moved downward. And move it up to the building side. As a result, as shown in FIG. 32 (b), the latching piece 212 of the roof member 202 a is in a state of being hooked on the engaging portion 230 of the eaves edge mounting bracket 200. That is, the latching piece 212 of the roof member 202a enters the space 231 formed below the engaging portion 230, and the eave end side end of the roof member 202a in the first row of eaves side is the eave end. It will be in the state latched by the attachment metal fitting 200. FIG.

Then, as shown in FIG. 33, the ridge side portion of the roof member 202a is fixed to the roof base together with the hanging member 269 in a state where the eave end side end portion of the roof member 202a is hooked on the eave end mounting bracket 200. More specifically, as shown in FIG. 34, a hanging member 269 is placed on the roof member 202a, and the overlapped roof member 202a and the hanging member 269 are fixed to the roof base via a fastening element 274.
As a result, the roof member 202a in the first row of the eaves side is attached on the roof base.

  Here, as described above, when the roof member 202a is mounted on the roof base, the hook piece 212 is hooked on the eaves mounting bracket 200 at the eaves side end of the roof member 202a. . In this state, since the upward movement of the roof member 202a is blocked by the eaves-end fitting 200, the roof member 202a does not float even if it is beaten by a strong wind. That is, in the roof structure 1 of the present embodiment, it is possible to attach the roof member 202 which is resistant to wind damage and does not peel even when the roof member 202a is blown by strong wind.

  Further, when the roof member 202a in the first row of the eaves side is attached, as shown in FIG. 32, the roof member 202a covers the fixing screw hole 229 of the eaves tip mounting bracket 200 from above. . Thus, since the roof member 202a covers the entire upper area of the region where the fixing screw hole 229 is formed in the lower plate portion 224 of the eaves mounting bracket 200, the roof base 202 is fixed from the fixing screw hole 229 of the eaves mounting bracket 200. Rainwater does not enter the side.

  And as above mentioned, the front through-hole 232 is provided in the front standing wall part 225 of the eaves edge attachment metal fitting 200 (refer FIG. 22). For this reason, even if rainwater enters the space 272 (see FIG. 32) formed between the upper plate portion 226 and the lower plate portion 224, the rainwater that has entered from the front through-hole 232 is removed from the outside. Can be discharged. Further, when the front through-hole 232 is formed in the front standing wall portion 225 in this way, most of the front standing wall portion 225 is cut out, so that the eaves tip mounting bracket 200 can be reduced in weight. Thereby, the weight of the roof structure 1 can be achieved.

  Further, as a third step, the roof members 202 in the second and subsequent rows on the eaves side are attached. That is, the roof member 202b in the second row of the eaves side, the roof member 202c in the third row of the eaves side, are installed on the roof base.

  First, as shown in FIG. 35, the roof member 202b in the second row of eaves side is installed on the roof base. At this time, as shown in FIG. 36, the latching piece 212 of the roof member 202b in the second row of eaves side is put into the roof material latching space 214 of the roof member 202a in the first row of eaves side. Make it hooked. That is, as shown in FIG. 36A, the latching piece 212 of the roof member 202b in the second row is connected to the eaves side (the eaves side 213 of the roof projection 202c of the roof member 202a in the first row). It is located on the right side of FIG. From this state, the latching piece 212 of the roof member 202b in the second row is moved to the vicinity of the surface of the roof member 202a in the first row, and is pulled up to the ridge side. As a result, as shown in FIG. 36B, the latching piece 212 of the roof member 202b in the second row is placed in the roof material latching space 214 of the roof member 202a in the first row. It enters the state. As a result, the end of the eaves side of the roof member 202b in the second row of eaves is hooked.

Then, as shown in FIG. 37, the ridge side of the roof member 202b in the second row of eaves side in the state where the end portion on the eave side of the roof member 202b in the second row of eaves side is hooked. The part is fixed to the roof base together with the hanging element 269.
Note that the method for fixing the ridge side portion of the roof member 202b in the second row of eaves side is the same as the method for fixing the ridge side portion of the roof member 202a in the first row of eaves side. Omitted.

  Thus, the roof member 202b of the row | line | column of the eaves side 2nd row is attached on a roof base | substrate by fixing a ridge side part in the state in which the eaves edge side edge part was latched.

  Furthermore, as shown in FIG. 38, the roof member 202 in the second row of the eaves side, such as the roof member 202c in the second row of the eaves side, as well as the roof member 202 in the second row of the eaves side. It is attached in the same manner as 202b. And when all the roof members 202 are attached on the roof base, the laying of the roof members 202 on the roof base is completed, and the foundation roof structure 203 is completed.

  Next, as a fourth step, the rail member 3 is attached to the foundation roof structure 203 on which the roof member 202 is laid.

  First, as shown in FIG. 39, the rail members 3a in the first row of eaves side are attached on the roof base. More specifically, a part of the rail connection piece 64 of the rail member 3a in the first row of the eaves side is divided into a roof member 202a in the first row of eaves side and a roof member 202b in the second row of eaves side. Insert into the gap formed in the heavy part. Then, in this state, the eave end side end of the rail member 3a in the first row of eaves side is fixed on the roof member 202 by a fastening member (not shown) such as a bolt. At this time, the rail member 3a is arranged so that the longitudinal direction of the rail member 3a is along the inclination direction of the roof. The majority of the rail members 3a in the first row of the eaves side are located on the roof member 202b in the second row of the eaves.

Next, as shown in FIG. 40, the rail members 3b in the second row of eaves side are attached on the roof base. Specifically, a part of the rail connection piece 64 of the rail member 3b in the second row of eaves side is divided into a roof member 202b in the second row of eaves and a roof member 202c in the third row of eaves. Insert into the gap formed in the heavy part. At this time, the eave end side end portion of the rail member 3b in the second row of the eaves side is fitted into the ridge side end portion of the rail member 3a in the first row of the eave side from the upper side, A part of the rail member 3a in the row column and a part of the rail member 3b in the second row of the eaves side overlap each other in close contact with each other in the height direction (a direction orthogonal to the beam direction and the column direction). It becomes a state.
Specifically, as described above, the rail member 3 has a structure in which the length in the width direction is different at both ends in the longitudinal direction. For this reason, a part of the two rail members 3a and 3b is partially covered by covering a portion where the length in the width direction of one rail member 3a is short with a portion where the length in the width direction of the other rail member 3b is long. It can be connected in the longitudinal direction (row direction 1) in a state of overlapping while closely contacting.
Thus, in the state where the two rail members 3a and 3b overlap, the portion overlapped by the fastening member (not shown) such as a bolt is inserted, and the ridge side end of the rail member 3a in the first row of the eaves side And the eaves side end of the rail member 3b in the second row of the eaves side are fixed on the roof member 202.

  And also when attaching the rail member 3 of the column after the eaves side 2nd row, it attaches similarly to the rail member 3b of the column of the eaves side 2nd row. And finally, attachment of the rail member 3 is completed by fixing the ridge side edge part of the rail member 3 located in the uppermost stage with fastening members (not shown), such as a volt | bolt.

Further, as a fifth step, the fixing member 5 is attached to the rail member 3 as shown in FIG.
At this time, the engaging portion 53 of the base portion 21 is inserted into the engaging hole 6 of the rail member 3 as shown in FIG. That is, the engaging portion 53 is inserted so that the width direction w of the engaging portion 53 of the base portion 21 substantially matches the extending direction of the engaging hole 6 of the rail member 3. In other words, the engaging portion 53 is inserted into the engaging hole 6 of the rail member 3 such that the thickness direction of the engaging portion 53 of the base portion 21 is aligned with the opening width direction of the engaging hole 6. Note that “substantially coincidence” here is a concept that includes not only perfect coincidence but also a slight inclination. In the present embodiment, the inclination of the engaging portion 53 from −10 degrees to 10 degrees with respect to the extending direction of the engaging hole 6 is represented.

Next, the connecting portion 57 (see FIG. 12) of the base portion 21 is rotated in the circumferential direction as indicated by the arrow in FIG. 42 (a), and the shaft portion of the fixing bolt 8 as shown in FIG. 42 (b). 12 is inserted into the through hole 58, and the fixing bolt 8 is temporarily tightened with a known nut (engagement posture).
At this time, the width direction w (see FIG. 7) of the engaging portion 53 of the base portion 21 faces the direction intersecting the extending direction of the engaging hole 6 of the rail member 3. In other words, the member thickness direction of the engaging portion 53 of the base portion 21 faces the direction intersecting the opening width direction of the engaging hole 6. In the present embodiment, the member thickness direction of the engaging portion 53 of the base portion 21 faces the direction orthogonal to the opening width direction of the engaging hole 6.
When the locking piece 56 of the engaging portion 53 is engaged with the engaging hole 6 of the rail member 3, the movement of the fixing member 5 with respect to the rail member 3 in the separating direction is restricted. In other words, the fixing member 5 cannot be detached from the rail member 3. That is, even when negative pressure is applied from the outside, the fixing member 5 does not leave the rail member 3.

Further, the bottom surface portions 45 and 46 are placed on the upper surface of the rail member 3. The positional relationship between the fixing bolt 8 and the fixing member 5 is restricted, and the fixing tool 7 and the fixing member 5 can be integrally slid only in the extending direction of the slit-like engagement hole 6 of the rail member 3.
The fixing member 5 is movable along the longitudinal direction of the rail member 3 when the fixing bolt 8 is temporarily tightened, and relatively fixed with respect to the rail member 3 when the fixing bolt 8 is in the fully-fastened state. It is mounted in an immovable state.

With the completion of the attachment of the fixing member 5 to the rail member 3 in the fifth step, the installation of the members for attaching the solar cell panel 2 on the roof (the eaves-end fitting 200, the rail member 3, the fixing member 5) is completed. To do.
And the solar cell panel 2 is installed on the foundation roof structure 203 continuously.

  Subsequently, in the sixth step to be carried out, as shown in FIGS. 43 and 44, the solar cell panels 2a in the first row of eaves side are attached on the roof base.

At this time, the eaves side end of the solar cell panel 2a is fitted into the module holding recess 219 of the eaves mounting bracket 200. Then, as shown in FIG. 45, the eaves-side front end portion of the solar panel 2a in the first row of eaves side and the eaves-side front end portion of the roof member 202a in the first row of eaves side, The positions are substantially the same in the row direction l (the roof inclination direction). At this time, the eaves-side front end portion of the solar cell panel 2a in the first eave side row and the eaves-side front end portion of the roof member 202a in the first eave row column are both the roof base (field plate). 268) is very close to the edge of the eaves side. In other words, the eaves-side front end portion of the eaves-side first row of the solar cell panels 2a and the eaves-side front end portion of the eaves-side first row of the roof members 202a are both roof bases (field boards). 268) is substantially the same position as the front end portion of the eaves side, and is overlapped in the height direction.
That is, in the roof structure 1 of the present embodiment, the eaves side ends of the solar cell panel 2 and the roof member 202 can be laid very close to the eaves side ends of the roof base (field plate 268). In this way, there is almost no gap from the protruding end (front side) of the roof eaves to the ridge side (rear side) by forming an area where the solar cell panel 2 can be installed at the eaves protruding end portion of the roof. The solar cell panel 2 can be laid. In other words, according to the roof structure 1 of the present embodiment, there is almost no area where the solar cell panel 2 cannot be installed on the roof, and the solar cell panel 2 can be installed in almost all parts on the roof. The solar cell panel 2 can be installed.

Next, as shown by the arrow in FIG. 46 (a), the fixing tool 7 and the fixing member 5 are integrally slid in the extending direction of the engaging hole 6, and the side of the rectangular solar cell panel 2a in the row direction l is formed. As shown in FIG. 46B, the fixing bolt 8 is finally tightened with a known nut.
At this time, the fixing member 5 is attached to an intermediate portion in the width direction w (column direction) of the solar cell panel 2a. That is, the upper end of the solar cell panel 2a in the row direction l is inserted into one fixed space 30 (front fixed space 30a) (see FIG. 10) of the holding unit 20. Specifically, the sides of the solar cell panel 2 are sandwiched between the upper surface attachment portion 31 and the lower surface attachment portion 32 of the friction applying member 25. That is, the ridge portion 38 is in pressure contact with the upper surface of the solar cell panel 2.
At this time, the sides located at both ends in the column direction w of the solar cell panel 2a are both free ends. That is, the region in the vicinity of the two sides of the solar cell panel 2 located on both ends of the column direction w is fixed in a cantilever manner by the fixing member 5.

In this way, the attachment of the solar cell panels 2a in the first row of the eaves side to the roof base is completed.
Here, when the solar cell panel 2 is attached with the eaves tip attachment tool 200 of the present embodiment, a wide gap is formed between the solar cell panel 2 and the roof member 202 (see FIG. 45). This gap becomes a space through which the rainwater flows when the rainwater flows below the solar cell panel 2. That is, when the solar cell panel 2 is attached with the eaves tip attachment tool 200 of the present embodiment, rainwater does not collect between the roof member 202 and the solar cell panel 2 and flows toward the eaves side.

  Further, as a seventh step, as shown in FIGS. 48 and 49, the solar cell panels 2 in the columns on and after the second row of eaves are installed.

First, as shown in FIG. 47, the connecting piece 100 is attached to the ridge side end of the solar cell panel 2a in the first row of the eaves side. In other words, as shown in FIGS. 47 (a) to 47 (b), the connecting piece 100 is attached to the side concentration part 101 where corners of the solar cell panels 2a adjacent to each other in the column direction w overlap each other and the vicinity thereof.
At this time, the connecting piece 100 is attached to each of the ridge-side end portions of the two solar cell panels 2a adjacent to each other in the column direction w (column direction) and the boundary between the two solar cell panels 2a. When viewed from the connection piece 100 side, the connection piece 100 is attached to the connection piece 100 across the two solar cell panels 2a adjacent to each other in the column direction w. In other words, the connection piece 100 is attached across the boundary between the two solar cell panels 2a adjacent to each other in the column direction w. Specifically, in the front fixed space 130a (see FIGS. 17 and 18) of the connecting piece 100, there are two solar panels 2a arranged in the column direction w, which are the solar cell panels 2a in the first row of eaves. The adjacent corner portions of the battery panel 2a are fitted.
That is, the side concentration part 101 of the solar cell panel 2 and the vicinity thereof are inserted into the front fixed space 130a (see FIGS. 17 and 18) of the connection piece 100. Specifically, the side concentration portions 101 of the solar cell panels 2 a adjacent to each other in the column direction w are sandwiched between the upper surface attachment portion 131 and the lower surface attachment portion 132 of the friction applying member 125. That is, the ridge portion 138 (see FIG. 19) presses the upper surface of the solar cell panel 2.
At this time, the connecting piece 100 is lifted together with the solar cell panel 2 by the solar cell panel 2 adjacent in the column direction w, and is in an airborne state. That is, a space is formed below the connection piece 100.

  In this state, the eaves side end of the solar cell panel 2b in the second row of eaves side is fixed by the fixing member 5. More specifically, the solar cell panel 2b in the second row of the eaves side is placed in the rear fixed space 30b of the fixing member 5 that fixes the ridge side portion of the solar cell panel 2a in the first row in the eave side. The eaves side end is fitted. That is, the holding portion 20 (see FIG. 7) of the fixing member 5 holds the ridge-side end portion of the solar panel 2a in the first row of eaves in the front fixing space 30a (see FIG. 10), and is fixed rearward. The space 30b (see FIG. 10) is in a state where the eaves end side ends of the solar cell panels 2b in the second row of eaves are held.

  At this time, the eave end side end portion of the solar cell panel 2b in the second row of eaves side is fitted in the rear fixed space 130b (see FIGS. 17 and 18) of the connection piece 100. That is, the connecting piece 100 fixes the eaves side end portions of the two solar cell panels 2b adjacent in the column direction w (column direction). Moreover, the connection piece 100 is the state fitted in the back fixed space 130b across the boundary of the two solar cell panels 2b. More specifically, the rear fixed space 130b of the connecting piece 100 is in a state in which adjacent corners of the solar cell panels 2b in the second row of eaves are fitted.

At this time, the side concentration portion 101 where the corner portions of the solar cell panels 2 adjacent to each other in the column direction w overlap and its vicinity are inserted into the rear fixed space 130b (see FIGS. 17 and 18) of the connection piece 100.
Specifically, the corner portion of the solar cell panel 2 b is sandwiched between the upper surface attachment portion 131 and the lower surface attachment portion 132 of the friction applying member 125. That is, the ridge portion 138 is in pressure contact with the upper surface of the solar cell panel 2.
At this time, the connecting piece 100 is lifted together with the solar cell panel 2 by the solar cell panel 2 adjacent in the column direction w and the solar cell panel 2 adjacent in the row direction l, and is in an airborne state. . That is, a space is formed below the connection piece 100. Therefore, the connection piece 100 and the solar cell panel 2 are supported at both ends, and the rigidity is high.

  That is, the connecting piece 100 has four corners of the adjacent solar cell panels 2a in the first row of eaves side and the two solar cell panels 2b adjacent in the row direction l (the step direction and the beam direction).
