The weight can be greatly reduced. Since the battery body 2 is composed of a film-type amorphous solar cell, the solar cell module P can be easily lengthened compared to a conventional crystal module, and the production efficiency of the solar cell module can be improved accordingly, Can save time and effort.

  The base body 1 is composed of a main surface wall 3 to which the battery body 2 is attached and fixed, a locking wall 4 that is bent along both side edges of the main surface wall 3, and a fastening wall 7. Since the solar cell module P is directly supported by the fastening metal fitting 25 by sandwiching the fastening wall 7 with the fastening metal fitting 25 attached to the portion 19, the crystalline solar cell module or the conventional solar cell module reduced in weight can be used. Compared to this, the structure is simple and lightweight, and the versatility is high, so that the productivity can be improved correspondingly, and the labor of inventory management can be simplified.

The handling of the load can be further facilitated by restricting the base body 1 from being bent and deformed at the time or during construction.

  In the exterior panel mounting structure according to the present invention, the exterior panel P is directly supported by the fastening brackets 25 attached to the connecting portions 19 of the adjacent folding plates 16, so that the necessary brackets for supporting the exterior panel P are provided. The overall weight including the exterior panel and the mounting structure can be greatly reduced. Furthermore, the fastening base 25 is composed of the support base 26 fastened and fixed to the connecting portion 19 and the presser 27, and the fastening wall 7 of the exterior panel P is directly clamped and fixed by the support base 26 and the presser 27. For example, when the solar cell module is installed on the roof surface, a frame, a metal fitting for fixing the frame, etc., which have been indispensable in the conventional structure of this type, can be omitted, and the load weight on the roof and the building frame can be reduced. Of course, construction work and installation costs can be greatly reduced by the amount that can be omitted.

  Since the exterior panel P is supported outside the connecting portion 19, the structure and shape of the exterior panel P can be simplified. For example, a groove or the like for avoiding contact interference with the connecting portion 19 is formed in the base body 1. Since there is no need, the exterior panel P can be installed regardless of the working width of the folding plate and the panel size. Therefore, there is an advantage that the versatility of the exterior panel P can be improved and its manufacturing cost can be reduced. The exterior panel P can be easily installed on a newly constructed roof or outer wall as well as on an existing roof or outer wall.

The retaining wall 4 of the exterior panel P is latched and attached to the retaining groove 37, and the fastening wall 7 supported by the both mounting walls 36 is clamped to the both mounting walls 36 of the support base 26 and the support base 26. According to the mounting structure of the exterior panel P sandwiched and fixed by the pressing arm 46 of the tool 27, the fastening walls 7 on both sides of the main surface wall 3 are directly sandwiched and fixed by the fastening bracket 25, and the exterior panel P is in a stable state. Can be firmly fixed. Since the exterior panel P is directly fixed and supported by the fastening bracket 25, the installation structure can be simplified compared to the conventional installation structure, and the construction cost can be reduced accordingly.

  The support base 26 is constituted by a pair of mounting legs 34 sandwiching the neck portion 20 of the helical tightening structure 19 and a pair of mounting walls 36 continuous to the mounting legs 34, and a connecting groove formed by cutting out the mounting wall 36. 48, the engaging wall 4 and the fastening wall 7 of the exterior panel P are engaged, and the fastening wall 7 is sandwiched between the pressing arm 46 of the presser 27 fastened to the support base 26 and the fastening surface 50 of the connecting groove 48. According to the mounting structure of the exterior panel P to be fixed, the exterior of the exterior panel P can be made clean by avoiding the presser 27 from projecting greatly to the outer surface of the exterior panel P. The locking wall 4 and the fastening wall 7 of the exterior panel P can be positioned by the connecting groove 48, and the exterior panel P can be reliably restricted from moving toward the eave building.

  On the roof or the outer wall where the crest portions 18 of adjacent folding plates 16 are connected and fixed with bolts 53, the support base 26 and the presser 27 are fixed to the connecting portion 19 using the bolts 53, and simultaneously supported. According to the mounting structure of the exterior panel P in which the fastening wall 7 of the exterior panel P is sandwiched and fixed by the mounting wall 57 of the base 26 and the pressing arm 59 of the presser 27, the support base 26 is fixed to the connecting portion 19. The structure of the fastening bracket 25 can be simplified by omitting bolts and bolts for fastening the presser 27 to the support base 26, and the labor and installation cost of the exterior panel P can be greatly reduced by that much. The load weight on the roof and the building frame can be further reduced. Each of the mounting wall 57 of the support base 26 and the pressing arm 59 of the presser 27 is formed in an inverted L shape, and the mounting wall 57 and the pressing arm 59 sandwich the fastening wall 7 of the exterior panel P up and down. Therefore, there is also an advantage that the appearance of the exterior panel P can be made clean by avoiding that the entire support base 26 and most of the presser 27 are protruded upward from the surface of the base body 1.

  A pair of placement walls provided on the support base 26 are formed in a stepped manner with a lower placement wall 36L and a higher placement wall 36H, and a pair of pressing arms provided on the presser 27 is provided with a lower pressure. A state in which the arm 46L and the high pressure arm 46H are formed in a stepped manner, and the fastening wall 7 of the exterior panel P is inclined to the lower placement wall 36L and the higher placement wall 36H of the adjacent support base 26. According to the mounting structure of the exterior panel P that is mounted and fixed by the presser 27, the exterior panel P can be attached to the roof surface or the outer wall in a largely inclined state. In particular, when the exterior panel is the solar cell panel P installed on the roof surface, the inclination angle of the solar cell panel P between the adjacent fasteners 25 and 25 is added to the slope of the roof surface of the battery panel P. Since it can be supported with a large inclination angle, even if the roof surface is formed with a gentle slope, the amount of electric power that can be supplied by improving the power generation efficiency of the solar cell panel P can be increased. Moreover, since the inclination angle of the solar battery panel P is large, dust such as dust adhering to the panel surface can be effectively washed away by rainwater, and therefore, the sunlight transmission on the panel surface is promoted, so that Power generation can be performed effectively. Since it is not necessary to prepare special parts separately to support the exterior panel and solar panel P at an angle, the load weight on the roof and the building frame can be reduced, and there is also the advantage that construction labor and installation costs can be greatly reduced. is there. When installing a cosmetic exterior panel, it is possible to reliably clean the surface with rain water and maintain a beautiful state for a long time.

According to 46 and 59, the strength of the pressing arms 46 and 59 can be increased. Further, in the state in which the presser 27 is fastened, the fastening wall 7 can be firmly clamped and fixed while the upper arm walls 46a and 59a are elastically deformed, so that it is possible to reliably prevent the exterior panel P from flapping or floating due to strong wind.

  As shown in FIG. 8, the restriction piece 46 c is formed continuously on the lower arm wall 46 b, and the engagement wall 4 and the reinforcing wall 6 attached to the engagement groove 37 are connected to the restriction piece 46 c and the engagement groove 37. According to the mounting structure of the exterior panel P that is clamped and fixed with one of the groove edges, the restricting piece 46c is received by the locking groove 37 when the nut 31 is tightened, and the presser 27 is reliably prevented from being rotated. Therefore, the fastening operation of the presser 27 can be performed quickly and easily.

  When the exterior panel is a solar cell module P in which the battery body 2 made of a film-type amorphous solar cell is bonded and fixed to the main surface wall 3 of the base body 1, the installation structure of the solar cell module P on the roof surface or outer wall The construction cost can be greatly reduced as compared with the conventional installation structure, and the overall weight of the roof can be reduced or the load weight on the building frame can be reduced by the simple installation structure. Since the solar cell module P can be installed regardless of the working width of the folding material and the panel size, the versatility of the solar cell module P itself can be greatly improved, and the manufacturing cost can be reduced.

In this way, when the outer surface of the main surface wall 3 including the outer surface of the battery body 2, the locking walls 4, 4, the side end walls 5, 5 and the reinforcing walls 6, 6 are entirely covered with the exterior film 12. Since the corrosion resistance and durability of the base body 1 can be improved, a solar cell module P that can generate power in a stable state over a long period of time can be obtained.

  The film-type amorphous solar cell described above has features that can reduce the weight per unit area and can be placed even on a curved surface compared to a crystalline solar cell in which a solar cell layer is formed on the surface of a glass substrate. Have. Incidentally, the battery body 2 of this embodiment has a weight of only 1 kg per square meter, and can be reduced to 1/10 as compared with a conventional crystalline solar battery. The film substrate 10 and the exterior film 12 are formed using a weather resistance, in particular, a plastic material that is not easily deteriorated by ultraviolet rays, such as a fluororesin.

  The solar cell module P reduced in weight as described above is installed, for example, on a folded roof shown in FIGS. 4 and 5. The folding roof material (folding plate material) 16 constituting the roof has crest portions 18 formed at both ends of the inverted trapezoidal valley portion 17, and seam joints 19 a and 19 b are formed at the ends of the crest portions 18. It is. By placing the mountain portion 18 of the adjacent folding roof material 16 on the upper surface of the tight frame 21 fixed to the roof base, and tightening the joints 19a and 19b around the suspension 22 fixed to the tight frame 21, The adjacent folded roof materials 16 can be connected and fixed in a non-separable manner by a fastening structure (connecting portion) 19.

  By directly supporting the solar cell module P with a group of fastening fittings 25 fixed to the helical fastening structure 19, the overall structure of the solar cell system can be simplified. 1, 4, and 5, the fastening bracket 25 includes a clip-like support base 26 that is fastened and fixed to the hull fastening structure 19, and the fastening wall 7 of the solar cell module P is vertically moved together with the support base 26.

It consists of a press fitting integrally provided with a fastening frame 35 having a U-shaped cross section and a pair of mounting walls 36 formed continuously at both ends of the fastening frame 35 in the eaves-ridge direction. The cross section of the fastening frame 35 and the mounting wall 36 is generally similar, the mounting wall 36 is formed slightly smaller than the fastening frame 35, and the upper surface of the mounting wall 36 is formed in a paragraph shape from the upper surface of the fastening frame 35. is doing.

  A vertical slit-like locking groove 37 is cut out from the upper wall of the mounting wall 36 to the upper half of the left and right side walls, and the locking wall 4 and the reinforcing wall 6 of the base body 1 are engaged and mounted in this groove 37. I can do it. The groove width of the locking groove 37 is set to be the same as or slightly larger than the total thickness dimension between the outer surfaces of the locking wall 4 and the reinforcing wall 6. As shown in FIG. 1, each mounting wall 36 receives and supports the fastening wall 7 of the base body 1 by a receiving wall 38 sandwiched between the locking groove 37 and the eaves end or the ridge end of the mounting wall 36. Insertion holes 39 for inserting the first bolts 28 are formed in the left and right side walls constituting the fastening frame 35, and the second bolt 30 is formed on the upper wall of the fastening frame 35 with the screw shaft protruding upward. It is fixed.

  Below, the construction example of the solar cell module P is shown. In the construction example shown in FIG. 2, the fastening brackets 25 are fixed at intervals of two pitches (every other pitch) of the screw fastening structure 19 adjacent in the lateral direction, and the fastening brackets 25 are further provided at positions spaced apart from each other in the eaves ridge direction. The left and right horizontally long solar cell modules P were fixed with a total of eight fasteners 25 arranged in a staggered manner. When the fastening brackets 25 are arranged in a staggered manner in this way, the number of the fastening brackets 25 installed can be reduced. The ends of the solar cell modules P adjacent in the left-right direction are adjacent to each other through a slight gap, and are installed so that the adjacent gap portion in the left-right direction is located immediately above the valley portion of the roofing material. This is because the output cables derived from the respective solar cell modules P are arranged along the valleys.

  At the time of construction, a group of support bases 26 on the eaves side are temporarily assembled in the fastening structure 19 and positioned in the eaves ridge direction, and the nut 29 is completely tightened to the first bolt 28, as shown in FIG. The support base 26 is fixed to the fastening structure 19 by pulling the pair of mounting legs 34 and holding the neck portion 20 therebetween. Similarly, after temporarily assembling the group of support bases 26 on the building side to the fastening structure 19, the locking walls 4 and the reinforcing walls 6 of the solar cell module P are locked to the support bases 26 located on the eaves side. The inner surface of the fastening wall 7 is received by the receiving wall 38 by being fitted into the groove 37 from above. The locking wall 4 and the reinforcing wall 6 fitted in the locking groove 37 are locked and held so that their outer surfaces come into contact with both groove edges of the locking groove 37 and are not allowed to float.

  At the same time, the locking wall 4 and the reinforcing wall 6 of the solar cell module P are fitted from above into the locking groove 37 of the support base 26 positioned on the temporarily assembled ridge side, so that the support base 26 positioned on the ridge side is provided. Positioning in the ridge direction, the inner surface of the fastening wall 7 on the ridge side is received by the receiving wall 38. In this state, the nut 29 is completely fastened to the first bolt 28 to fix the ridge-side support base 26 to the screw fastening structure 19. Next, the presser 27 is inserted into the second bolt 30 provided on the support base 26 and the nut 31 is temporarily assembled. In this state, the solar cell module P is positioned in the left-right direction, and the nut 31 is completely tightened so that the fastening wall 7 is sandwiched and fixed between the receiving wall 38 and the pressing arm 46, and the fastening wall 7 is a screw-fastening structure 19. The solar cell module P can be fixed in a state of being positioned higher.

  Similarly, by installing a group of solar cell modules P in order in the left-right direction and the eaves building direction, a solar power generation apparatus having a large total area and a large amount of generated power can be constructed as shown in FIG. it can. Although not shown, the electric power generated by each solar cell module P is output to an output regulator via an output cable derived from the individual module, where the voltage is adjusted and then converted into an alternating current. Supplied to commercial power.

  Depending on the adjacent pitch of the peak portion 18 of the folded roofing material 16 and the fastening structure 19, if the adjacent pitch of the fastening structure 19 is relatively small, the fastening is performed as described above. The fastening brackets 25 may be fastened every three pitches of the structure 19, and when the adjacent pitch of the adjacent fastening structures 19 is large, the fastening hardware 25 is fastened to all the adjacent fastening structures 19. The base body 1 is preferably supported.

  7 to 9 show modified embodiments of the presser 27, respectively. In FIG. 7, the pressing arm 46 is composed of an upper arm wall 46 a that continues to the fastening portion 45 and a lower arm wall 46 b that is folded back on the lower surface side of the upper arm wall 46 a to enhance the strength of the pressing arm 46. . Moreover, since the fastening wall 7 can be clamped and fixed in a state where the upper arm wall 46a is elastically deformed, the solar cell module P can be reliably prevented from fluttering by strong wind. Since others are the same as the previous embodiment, the same reference numerals are assigned to the same members, and descriptions thereof are omitted. Similarly, in the following embodiments, only differences from the previous embodiments will be described.

  In FIG. 8, the restriction piece 46 c is bent downward and formed continuously with the lower arm wall 46 b, and the locking wall 4 and the reinforcing wall 6 are fitted in the locking groove 37. The restricting piece 46c is inserted and engaged with the outer surface side so that the locking wall 4 and the reinforcing wall 6 can be clamped and fixed by one groove edge of the locking groove 37 and the restricting piece 46c. As described above, according to the fastening bracket 25 that locks the restricting piece 46c in the locking groove 37, it is possible to reliably prevent the presser 27 from being rotated when the nut 31 is tightened, and to tighten the presser 27. Can be done quickly.

  In the solar cell module P shown in FIG. 9, the fastening wall 7 is formed to be bent obliquely upward continuously to the lower end of the locking wall 4. In connection with such a change in the formation position of the fastening wall 7, a connecting groove 48 that receives the locking wall 4 and the fastening wall 7 is formed in the mounting wall 36 of the support base 26. The connecting groove 48 is formed in a V shape by a vertical groove edge 49 to which the locking wall 4 is locked and a fastening surface 50 made of an inclined surface that receives the previous fastening wall 7. Further, the pressing arm 46 of the presser 27 is inclined obliquely downward at the same angle as the fastening surface 50.

  At the time of construction, the locking wall 4 and the fastening wall 7 of the solar cell module P adjacent in the eave building direction are dropped into the connection groove 48 of the support base 26 from above and engaged, and the presser 27 is assembled to the second bolt 30. After that, the fastening wall 7 can be clamped and fixed between the fastening surface 50 and the pressing arm 46 by tightening the nut 31. In the process of fixing the presser 27, the fastening wall 7 moves along the fastening surface 50 toward the groove depth of the coupling groove 48. At this time, the locking wall 4 is pressed against the groove edge 49 and positioned, so that the solar cell module P can be more reliably prevented from moving in the direction of the eaves.

  When the folded roofing materials 16 are connected to each other by a corner fastening structure 19, a support base 26 shown in FIG. 10 is used. In the helix structure 19 having a corner helix structure, the helix joints 19 a and 19 b are caulked and deformed on one side of the hanging member 22. For this reason, one mounting leg 34 of the support base 26 is formed to be substantially perpendicular to the fastening frame 35, and only the other mounting leg 34 is formed in a horizontal U shape. In a state where the support base 26 is fastened with the first bolts 28, the neck portion 20 of the fastening structure 19 is sandwiched and fixed by the vertical mounting legs 34 and the horizontal U-shaped mounting legs 34.

  The roof shown in FIG. 11 shows an embodiment in which the mountain portions 18 of the adjacent folding roof materials 16 are connected by bolts. In this case, the mountain portions 18 are stacked one above the other on the upper surface of the tight frame 21, and both mountain portions 18 are fastened with bolts (sword-tip bolts) 53, nuts 54, and washers 55 to connect adjacent folding roof materials 16. To do. Thus, in the folded roof structure connected with bolts, the fastening bracket 25 is fastened and fixed using the connecting portion 19 by the bolt 53. Alternatively, as shown in FIG. 12, the fastening bracket 25 is fixed to the mountain portion 18 of the folded plate roofing material 16 with a one-side bolt (bolt) 67 to support the solar cell panel P. The one-side bolt 67 in this case can be fixed to the mountain portion 18 where the tight frame 21 is not provided.

  The fastening bracket 25 includes a support base 26 whose cross section is formed in a reverse hat shape, and a presser 27 having a reverse hat cross section that is slightly smaller than the support base 26, both of which use a bolt 53 and a nut 54. And conclude. The support base 26 includes a central base wall 56 and a pair of placement walls 57 that are continuously bent into an inverted L-shape from the base wall 56. An insertion hole for the bolt 53 is formed in the center portion of the base wall 56, and a joint seat 56a having a partial arc shape is formed at both ends so as to bulge downward. The presser 27 is composed of a fastening portion 58 having an insertion hole for the bolt 53 and a pair of pressing arms 59 that are continuously bent in an inverted L shape to the fastening portion 58. The pressing arm 59 is composed of an upper arm wall 59a and a lower arm wall 59b that is folded back on the lower surface side of the upper arm wall 59a, like the presser 27 described in FIG.

  When constructing a solar cell system, the base wall 56 is inserted into and engaged with the bolt 53, and the support base 26 is temporarily assembled to the connecting portion 19. After the locking walls 4 of the solar battery panel P are respectively locked to the vertical walls of the mounting walls 57 on both sides of the eaves ridge direction, the fastening portions 58 of the presser 27 are inserted into the bolts 53 to receive the mounting walls 57. The fastening wall 7 is held up and down by the wall 60 and the pressing arm 59. In this state, the nut 54 is screwed into the bolt 53, and the presser 27 and the support base 26 are fastened and fixed. In this embodiment, the first bolt 28 and the nut 29 and the second bolt 30 and the nut 31 can be omitted, so that the structure of the fastening bracket 25 can be simplified and the cost can be reduced accordingly. Further, since the locking wall 4 is engaged and mounted on the vertical wall portion of the mounting wall 57, it is not necessary to provide the locking groove 37.

  In the solar cell panel mounting structure described above, since the solar cell panel P is installed parallel to the roof surface, it is inevitable that the power generation efficiency decreases when the roof surface is formed with a gentle slope. . In order to compensate for such a lack of gradient and improve the power generation efficiency of the solar cell panel P, the solar cell panel mounting structure can be configured as shown in FIG. 13 and FIG.

  1 to 6, the pair of mounting walls provided on the support base 26 in the fastening bracket 25 described with reference to FIGS. 1 to 6 are separated from a lower mounting wall 36 </ b> L having a small projecting dimension from the mounting legs 34 and the mounting legs 34. And a high mounting wall 36H having a large projecting dimension. The receiving wall 38 provided on the higher placement wall 36H is formed in a stepped shape continuously with the fastening frame 35 in the same manner as the fastening bracket 25 described with reference to FIGS. In addition, the receiving wall 38 provided on the lower placement wall 36 </ b> L is formed by a pair of walls divided by a groove 80 that is continuous with the locking groove 37. Further, corresponding to the stepped structure of the mounting walls 36L and 36H, a pair of pressing arms provided on the presser 27 is formed in a stepped manner with a lower pressing arm 46L and a higher pressing arm 46H. The upper pressing arm 46H is formed in the same manner as the presser 27 described with reference to FIGS. 1 to 6. However, the lower pressing arm 46L has a length of the vertical wall 81 of the lower and higher pressing arms 46L and 46H. The length is set corresponding to the step size.

  When constructing a solar cell system, as shown in FIG. 15, each support base 26 is placed in a state where the high placement wall 36H is located on the eaves side and the low placement wall 36L is located on the ridge side. The fastening wall 7 of the exterior panel P is mounted on the connecting portion 19 of the folded roofing material 16 so as to be inclined between the lower mounting wall 36L and the higher mounting wall 36H of the adjacent support base 26. By fastening the presser 27 in the manner described above, the eaves-side locking wall 7 is sandwiched and fixed by the lower mounting wall 36L and the lower pressing arm 46L, and the higher mounting wall 36H and the higher The ridge side locking wall 7 is clamped and fixed by the pressing arm 46H. Thereby, since the inclination angle of the solar cell panel P can be made into the value of the sum of the inclination of a roof surface, and the solar cell panel P inclination angle between the adjacent fasteners 25 and 25, a roof surface is loose. Even if it is formed with a gradient, the power generation efficiency of the solar cell panel P can be improved. Moreover, since the inclination angle of the solar battery panel P is large, dust such as dust adhering to the panel surface can be effectively washed away by rainwater, and therefore, the sunlight transmission on the panel surface is promoted, so that Power generation can be performed effectively.

  As described above, the pair of placement walls provided on the support base 26 are formed in a stepped manner by the lower placement wall 36L and the higher placement wall 36H. FIG. 7, FIG. 8, FIG. 9 and FIG. The present invention can be similarly applied to the fastener 25 described in each of the eleventh embodiments.

  In the fastening bracket 25 described with reference to FIGS. 1 to 5, the presser 27 in a state of being inserted into the second bolt 30 and temporarily assembled with the support base 26 can freely rotate around the second bolt 30. Therefore, when tightening the nut 31, it is necessary to hold the presser 27 so that the presser 27 cannot be rotated with one hand, and it takes time to fasten the presser 27. In order to save such time and perform the fastening operation of the presser 27 quickly, a restricting piece for preventing rotation can be provided integrally with the presser 27.

  Specifically, as shown in FIG. 16, a pair of restricting pieces 84 are bent downward at the opposing edges of the fastening portion 45 of the presser 27. Thus, according to the presser 27 to which the restriction piece 84 is added, the lower end of the restriction piece 84 is the fastening frame 35 of the support base 26 as shown in FIG. 17 in a state where the presser 27 is inserted into the second bolt 30. In this way, the presser 27 is restricted from freely rotating around the second bolt 30. Therefore, when the nut 31 is tightened, the nut 31 can be screwed in without having to hold the presser 27 so that the presser 27 cannot be rotated, and the fastening operation of the solar cell module P by the presser 27 can be easily performed. .

  FIG. 18 shows an embodiment in which a regulating piece 84 is added to the presser 27 described in FIGS. In this case, a pair of restricting pieces 84 are bent downward at each of the opposing edges of the fastening portion 45 of the presser 27. Also in this case, since the lower end of the restricting piece 84 is received by the fastening frame 35 of the support base 26 in a state where the presser 27 is inserted into the second bolt 30, the presser 27 is held in a non-rotatable manner as described above. The nut 31 can be screwed in without being held.

  The restricting piece 84 can also be added to each presser 27 described with reference to FIGS. 7 to 10, and in that case, the restricting piece 84 is formed at each of the opposing edges of the fastening portion 45 of each presser 27. To do. Further, if necessary, the restriction piece 84 can be bent and formed at each of the opposing edges of the fastening portion 58 of the presser 27 described with reference to FIGS. 11 and 12. The restricting piece 84 is preferably formed on each of the opposing edges of the fastening portion 45, but it is not necessary and may be formed on either one of the opposing edges of the fastening portion 45.

  In the above embodiment, the case where the solar cell module P is installed on the roof has been described. However, the mounting structure of the exterior panel according to the present invention can be applied to the case where an exterior panel other than the solar cell module P is installed. it can. The exterior panel in this case is used, for example, in order to make the impression on the exterior of the folded-plate roof clear. By using the same structure as that of the base body 1 described above, the exterior panel is attached to the roof surface by the fastening bracket 25. Can be installed.

  The mounting structure of the exterior panel (solar cell panel) of the present invention can also be applied to the case where the outer wall of the building is constructed of a folded plate material. For example, the outer wall of an airplane hangar may be constructed of a folding plate. In such a case, an exterior panel or a solar cell panel is installed on the outer surface of the outer wall to improve the design of the outer wall, or Solar power can be generated by the battery panel. In that case, the folding plate may be either a vertically stretched structure or a horizontally stretched structure, and in any case, the panel mounting structure of the present invention can be applied. What is necessary is just to determine the inclination direction of the solar cell panel P installed in an outer wall by the relationship with sunlight. For example, when the outer wall is constructed of a vertically-folded folding material, the side edge on the ground side of the solar cell panel P is supported by the high placement wall 36H, and the roof side of the solar cell panel P is supported. The edge may be supported by a lower mounting wall 36L. When installing a decorative exterior panel on the outer wall, it is possible to improve design by forming sawtooth-shaped deep irregularities on the outer surface of the wall.

  In addition to the above embodiments, the base body 1 can be formed of an aluminum plate or a stainless plate. The support base 26 can be constituted by a pair of metal fittings each integrally provided with a mounting leg 34, a fastening frame 35, and a placement wall 36. In this case, the second fastening base 35 is attached to the fastening frame 35 of one of the metal fittings. The bolt 30 may be fixed.
