It is fixed to the fixing member 39 via a draining plate 55. The eaves side of the draining plate 55 is disposed on the ridge side end of the eaves side solar cell module 7b.
On the closing cover 51, a pair of snow stoppers 65 are attached in the direction of the beam. The snow stopper 65 is integrally formed by bending a single metal plate such as stainless steel. The snow stopper 65 includes a bottom wall portion 67 installed on the closing cover 51, an upright wall portion 68 bent upward at a substantially right angle from an eave side end portion of the bottom wall portion 67, and an upright wall portion. An inclined wall portion 69 folded downward from the upper end of 68 with an inner angle of about 30 degrees, and is folded from the lower end of this inclined wall portion 69 toward the ridge side in the roof flow direction and overlapped with the ridge side of the bottom wall portion 67 from above. An attachment hole 71 is formed so as to be continuous with the bottom wall portion 67 and the connection wall portion 70. The bolt 73 is inserted into the attachment hole 71 of the snow stopper 65 and the attachment hole of the closing cover 51 from above, and is screwed into the nut 61 and tightened to fix the snow stopper 65 on the closing cover 51. .

前記実施の形態によれば、屋根材5が葺かれている既設の屋根1上に複数の太陽電池モジュール7を設置する場合、太陽電池モジュール7を棟側から軒側に向けて順次施工し、図2に示すように、太陽電池モジュール7の固定ブラケット23と挟持体35とで、屋根材5の軒側端部を挟持して、複数の太陽電池モジュール7を屋根材5上に配置し、固定ブラケット23上に取り付けている固定部材39上から、釘等の固定具48を打ち込んで、固定具48によって、固定部材39、固定ブラケット3、挟持体35及び2枚の屋根材5を野地板2側に固定すればよい。   According to the embodiment, when installing a plurality of solar cell modules 7 on the existing roof 1 on which the roofing material 5 is spread, the solar cell modules 7 are sequentially constructed from the building side toward the eaves side, As shown in FIG. 2, a plurality of solar cell modules 7 are arranged on the roof material 5 by sandwiching the eaves side end portion of the roof material 5 between the fixing bracket 23 and the sandwiching body 35 of the solar cell module 7. A fixing tool 48 such as a nail is driven from above the fixing member 39 attached on the fixing bracket 23, and the fixing member 39, the fixing bracket 3, the sandwiching body 35, and the two roofing materials 5 are placed by the fixing tool 48. What is necessary is just to fix to 2 side.

この際に、屋根流れ方向に隣り合う棟側の太陽電池モジュール7aと軒側の太陽電池モジュール7bとを、屋根流れ方向に互いに間隔Aをおいて配置し、棟側の太陽電池モジュール7aの設置位置と、軒側の太陽電池モジュール7bとの設置位置とを、屋根材5の屋根流れ方向の働き寸法Dの整数倍(例えば働き寸法Dの3倍)だけ屋根流れ方向にずらすようにする。
そして、閉塞カバー51の下面に固定した水切り板55を、リベット等の締結具62で固定部材39の取付部42,43に締結することによって、棟側の太陽電池モジュール7aと軒側の太陽電池モジュール7bとの間を閉塞カバー51で覆う。このとき、棟側の太陽電池モジュール7aと軒側の太陽電池モジュール7bとの間隔Aに寸法誤差等があっても、水切り板55をリベット等の締結具62で固定部材39に固定する際に、閉塞カバー51乃至水切り板55を、固定部材39乃至固定ブラケット23に対して屋根流れ方向に移動調整することによって、間隔Aの隙間を確実に塞ぐことができる。従って、棟側の太陽電池モジュール7aと軒側の太陽電池モジュール7bとの間を閉塞カバー51で塞いで外観上の体裁をよいものになし得る。また、閉塞カバー51によって、太陽電池モジュール7の若干の施工寸法ズレも吸収することができ、棟側の太陽電池モジュール7aの設置位置と、軒側の太陽電池モジュール7bとの設置位置とを、屋根材5の屋根流れ方向の働き寸法Dの整数倍(例えば働き寸法Dの3倍)だけ屋根流れ方向にずらしているため、屋根流れ方向に対応する複数の太陽電池モジュール7を屋根材5の流れピッチに対応させることができ、この点からも屋根1の外観上の体裁をよいものになし得る。
At this time, the ridge-side solar cell module 7a and the eaves-side solar cell module 7b that are adjacent to each other in the roof flow direction are arranged at an interval A in the roof flow direction, and the ridge-side solar cell module 7a is installed. The position and the installation position of the eaves side solar cell module 7b are shifted in the roof flow direction by an integral multiple of the working dimension D of the roof material 5 in the roof flow direction (for example, three times the working dimension D).
And the draining board 55 fixed to the lower surface of the obstruction | occlusion cover 51 is fastened to the attachment parts 42 and 43 of the fixing member 39 with fasteners 62, such as a rivet, and the solar cell module 7a on the ridge side and the solar cell on the eaves side The module 7b is covered with a closing cover 51. At this time, even when there is a dimensional error or the like in the distance A between the solar cell module 7a on the ridge side and the solar cell module 7b on the eaves side, the draining plate 55 is fixed to the fixing member 39 with the fastener 62 such as a rivet. By moving and adjusting the closing cover 51 to the draining plate 55 in the roof flow direction with respect to the fixing member 39 to the fixing bracket 23, the gap A can be reliably closed. Therefore, the space between the solar cell module 7a on the ridge side and the solar cell module 7b on the eaves side is closed with the closing cover 51, so that the appearance can be improved. Moreover, the construction cover of the solar cell module 7 can be absorbed by the closing cover 51, and the installation position of the solar cell module 7a on the ridge side and the installation position of the solar cell module 7b on the eave side are Since the roof material 5 is shifted in the roof flow direction by an integral multiple of the working dimension D in the roof flow direction (for example, three times the working dimension D), a plurality of solar cell modules 7 corresponding to the roof flow direction are arranged in the roof material 5. The flow pitch can be accommodated, and the appearance of the roof 1 can be improved from this point as well.

また、太陽電池モジュール7の縦幅寸法が、屋根材5の屋根流れ方向の長さ(働き寸法D)とは異なっていても、棟側の太陽電池モジュール7aと軒側の太陽電池モジュール7bとでは、太陽電池モジュール7を屋根1に固定するための釘等の固定具48を、各屋根材5に対して打ち付ける位置が、屋根流れ方向において一定になり、このため、屋根流れ方向に複数設けられた太陽電池モジュール7について、屋根材5の中央部等の好適な位置に釘等の固定具45を打ち付けて、複数の太陽電池モジュール7を屋根1上に良好に設置することができる。   Moreover, even if the vertical dimension of the solar cell module 7 is different from the length (working dimension D) of the roof material 5 in the roof flow direction, the solar cell module 7a on the ridge side and the solar cell module 7b on the eave side Then, the position where the fixing tool 48 such as a nail for fixing the solar cell module 7 to the roof 1 is struck against each roofing material 5 is constant in the roof flow direction. About the obtained solar cell module 7, the fixing tools 45, such as a nail, can be hit | damaged to suitable positions, such as the center part of the roofing material 5, and the several solar cell module 7 can be favorably installed on the roof 1. FIG.

また、閉塞カバー51上に雪止め具65が取け付られているので、雪止め具65が太陽電池10に対して太陽光線を遮る影の影響を極力少なくすることができ、雪止め具65を設けたことによって太陽電池モジュール7の発電効率を損なうおそれもなくなる。
また、閉塞カバー51の下側に、水切り板55が設けられ、水切り板55の軒側は、軒側の太陽電池モジュール7の棟側端部上に配置されているので、雪止め具65を閉塞カバー51に取り付けるためのボルトの取付孔から閉塞カバー51の下方に浸入した雨水等の水を、水切り板55で受けて、軒側の太陽電池モジュール7上にスムーズに排水することができる。また、水切り板55は、下方に没入した中央側の収納凹部56と上方に突出した一対の固定凸部57と下方に没入した外端側の一対の取付翼部58とを有し、桁行方向に凹凸を有する波形に形成されているため、閉塞カバー51の下方に浸入した雨水等の水を、桁行方向に大きく広がらないように収納凹部56等で屋根流れ方向に導いて、屋根流れ方向に案内することができる。また、水切り板55に凹凸を付けることで、雪止め具65からの荷重に対して強度を持たせることができる。また、太陽電池モジュール7の固定ブラケット23に固定部材39を一体に取り付けているので、一体化による取付精度を確保することができると共に、固定部材39に固定部40,41及び取付部42,43による凹凸を付けることで、水切り板55からの荷重に対して十分な強度を持たせることができる。
Further, since the snow stopper 65 is attached on the closing cover 51, the snow stopper 65 can minimize the influence of the shadow that blocks the solar rays on the solar cell 10, and the snow stopper 65 can be reduced. There is no risk of impairing the power generation efficiency of the solar cell module 7 due to the provision of.
Further, a draining plate 55 is provided below the closing cover 51, and the eaves side of the draining plate 55 is disposed on the ridge side end of the solar cell module 7 on the eaves side. Water such as rainwater that has entered the lower part of the closing cover 51 from the mounting hole of the bolt for attaching to the closing cover 51 is received by the draining plate 55 and can be smoothly drained onto the solar cell module 7 on the eaves side. The draining plate 55 has a central storage recess 56 recessed downward, a pair of fixed protrusions 57 protruding upward, and a pair of attachment wings 58 recessed outwardly, and in the direction of the row. In order to prevent the rainwater or the like that has entered under the closing cover 51 from flowing in the direction of roof flow in the storage recess 56 or the like so as not to spread significantly in the direction of the girder, I can guide you. Further, by providing unevenness on the draining plate 55, it is possible to give strength to the load from the snow stopper 65. In addition, since the fixing member 39 is integrally attached to the fixing bracket 23 of the solar cell module 7, it is possible to ensure attachment accuracy by integration, and to the fixing member 39, the fixing portions 40 and 41 and the attachment portions 42 and 43. By providing the unevenness due to, sufficient strength against the load from the draining plate 55 can be provided.

図8及び図9は他の実施の形態を示し、閉塞カバー51は、棟側カバー体77と軒側カバー体78とを備え、棟側カバー体77と軒側カバー体78とをボルトナット等の締結具79で屋根流れ方向に伸縮調整可能に連結したものである。即ち、棟側カバー体77と軒側カバー体78とには締結具79が挿通される取付孔80,81が設けられ、棟側カバー体77の取付孔80又は軒側カバー体78の取付孔81の一方は、屋根流れ方向の長孔により構成され、この長孔の範囲で、閉塞カバー51を屋根流れ方向に伸縮調整可能に構成している。その他の点は前記実施の形態の場合と同様の構成である。   8 and 9 show another embodiment, and the closing cover 51 includes a ridge side cover body 77 and an eaves side cover body 78, and the ridge side cover body 77 and the eaves side cover body 78 are bolt nuts or the like. These fasteners 79 are connected so that they can be expanded and contracted in the roof flow direction. That is, the ridge side cover body 77 and the eaves side cover body 78 are provided with mounting holes 80 and 81 through which the fasteners 79 are inserted, and the mounting hole 80 of the ridge side cover body 77 or the mounting hole of the eaves side cover body 78 is provided. One of 81 is comprised by the long hole of the roof flow direction, and it has comprised the obstruction | occlusion cover 51 so that expansion-contraction adjustment is possible in the roof flow direction in the range of this long hole. The other points are the same as those in the above embodiment.

従って、棟側の太陽電池モジュール7aと軒側の太陽電池モジュール7bとの間隔Aに相当の寸法誤差等が生じても、閉塞カバー51乃至水切り板55をリベット等の締結具62で固定部材39に固定する際に、閉塞カバー51を屋根流れ方向に伸縮調整することによって、間隔Aの隙間を確実かつ良好に塞ぐことができる。
図10は他の実施の形態を示し、閉塞カバー51上に取り付けた雪止め具65を省略すると共に、閉塞カバー51にボルト等の締結具を挿通するための取付孔の形成やナット61の取り付けを省略するようにしたものである。その他の点は前記実施の形態の場合と同様の構成である。
Therefore, even if a considerable dimensional error or the like occurs in the distance A between the solar cell module 7a on the ridge side and the solar cell module 7b on the eaves side, the closing cover 51 to the draining plate 55 are fixed to the fixing member 39 with the fasteners 62 such as rivets. When the cover cover 51 is fixed, the gap A of the gap A can be reliably and satisfactorily closed by adjusting the expansion and contraction of the closing cover 51 in the roof flow direction.
FIG. 10 shows another embodiment, in which the snow stopper 65 attached on the closing cover 51 is omitted, and the formation of an attachment hole for inserting a fastener such as a bolt into the closing cover 51 and the attachment of the nut 61 are shown.
