Similar to the roof material 101, the roof material 30 with a recess includes a claw portion 32 formed by protruding a ridge side end portion downward and a hanging portion 33 formed by protruding an eave side end portion downward. The nail | claw part 32 is hooked on the tile pier 104, and prevents the slippage of a roof material. The drooping portion 33 substantially contacts the upper surface of the roofing material 101 disposed on the eaves side of the roofing material 30 with a recess and prevents rainwater and dust from entering from the gaps between the roofing materials.

凹部付き屋根材３０は、爪部３２、垂れ部３３以外にも屋根材１０１と同様の構成（例えば、桟部、差し込み部）を有し、桁方向中央近傍が下方に凸となるように湾曲している。凹部３１は、詳しくは後述するように、当該桁方向中央近傍に形成されることが好適である。凹部付き屋根材３０の構成材料としては、特に限定されず、軽量セメント（繊維補強軽量セメント）や、アルミニウム等を主成分とする金属材料が例示できる。   The roof material 30 with a recess has the same configuration as the roof material 101 (for example, a crosspiece and an insertion portion) in addition to the claw portion 32 and the hanging portion 33, and is curved so that the vicinity of the center in the girder direction is convex downward. doing. As will be described later in detail, the recess 31 is preferably formed in the vicinity of the center in the girder direction. It does not specifically limit as a constituent material of the roofing material 30 with a recessed part, The metal material which has light weight cement (fiber reinforced lightweight cement), aluminum, etc. as a main component can be illustrated.

凹部３１は、凹部付き屋根材３０の棟側端部から長さＬ31（棟軒方向に沿った長さ）、幅Ｗ31（桁方向に沿った長さ）、深さＤ31で形成される窪みである。本実施形態では、金具２０の中間部２７が凹部３１に収まっている。凹部３１の長さＬ31は、屋根材１０１と凹部付き屋根材３０との重なり幅よりもやや長く設定される。また、長さＬ31は中間部２７の長さＬ27よりもやや長く設定されることが好ましい。幅Ｗ31は、凹部３１の全長に亘って略一定である。The recess 31 is formed with a length L 31 (length along the building eave), a width W 31 (length along the girder direction), and a depth D 31 from the ridge side end of the roof material 30 with a recess. It is a hollow. In the present embodiment, the intermediate portion 27 of the metal fitting 20 is accommodated in the recess 31. The length L 31 of the recess 31 is set to be slightly longer than the overlapping width between the roof material 101 and the roof material 30 with a recess. The length L 31 is preferably set slightly longer than the length L 27 of the intermediate portion 27. The width W 31 is substantially constant over the entire length of the recess 31.

凹部３１は、金具２０が屋根材１０１と接触しない状態で金具２０を収容可能に形成されることが好ましい（図３参照）。金具２０を屋根材１０１と接触させないことで、金具２０の屋根材１０１に対する干渉を確実に防止できる。具体的には、金具２０の形状、寸法、及び配置等に基づいて、金具２０と屋根材１０１とが接触しないように、凹部３１の形状、長さＬ31、幅Ｗ31、深さＤ31、及び配置等を設定する。さらに、凹部３１は、金具２０が凹部付き屋根材３０と接触しない状態で金具２０を収容可能に形成されることが好ましい。The recess 31 is preferably formed so that the metal fitting 20 can be accommodated in a state where the metal fitting 20 does not contact the roof material 101 (see FIG. 3). By not bringing the metal fitting 20 into contact with the roof material 101, interference of the metal fitting 20 with respect to the roof material 101 can be reliably prevented. Specifically, the shape, length L 31 , width W 31 , and depth D 31 of the recess 31 are set so that the metal fitting 20 and the roof material 101 do not come into contact with each other based on the shape, dimensions, arrangement, and the like of the metal fitting 20. , And arrangement etc. are set. Furthermore, it is preferable that the recessed part 31 is formed so that the metal fitting 20 can be accommodated in a state in which the metal fitting 20 does not contact the roof material 30 with the concave portion.

例えば、凹部３１は、長さＬ31を中間部２７の長さＬ27よりも長くすると共に、幅Ｗ31を中間部２７の幅Ｗ27よりも広くする。深さＤ31は、両端の壁の高さを含めた中間部２７の厚みよりも深くすることが好ましい。For example, the recess 31 has a length L 31 longer than the length L 27 of the intermediate portion 27 and a width W 31 wider than the width W 27 of the intermediate portion 27. The depth D 31 is preferably deeper than the thickness of the intermediate portion 27 including the height of the walls at both ends.

凹部３１の軒側端部の壁面は、屋根に固定された状態において、上部が下部よりも軒側に位置するように傾斜していることが好適である。これにより、凹部３１に入り込んだ雨水等を容易に流出させることができる。また、凹部３１、金具２０、及び屋根材１０１の隙間には、防水パッキン３６を設置することが好適である。   It is preferable that the wall surface of the eaves-side end of the recess 31 is inclined so that the upper part is located closer to the eaves side than the lower part in a state of being fixed to the roof. Thereby, the rainwater etc. which entered the recessed part 31 can be easily flowed out. In addition, it is preferable to install a waterproof packing 36 in the gap between the recess 31, the metal fitting 20, and the roof material 101.

凹部３１は、凹部付き屋根材３０の構成材料の厚みを部分的に薄くして形成されてもよいが、耐久性等の観点から、好ましくは他の部分と同じ厚みを確保して形成される。即ち、凹部３１の下側には、下方に突出する凸部が形成される。   The recessed portion 31 may be formed by partially reducing the thickness of the constituent material of the roof material 30 with the recessed portion. However, from the viewpoint of durability and the like, the recessed portion 31 is preferably formed while ensuring the same thickness as other portions. . That is, a convex portion that protrudes downward is formed below the concave portion 31.

凹部付き屋根材３０は、凹部３１を挟んだ桁方向両側に屋根材１０１が当接可能な荷重受け部３４を有することが好適である。凹部３１は、例えば、屋根材１０１と重なる棟側部分の桁方向中央近傍において、部分的に形成される。凹部３１の幅Ｗ31は、例えば、中間部２７の幅Ｗ27の１．１倍〜１．５倍程度に設定される。この場合、優れた施工性を維持しながら、屋根材１０１の荷重を凹部付き屋根材３０の上面（荷重受け部３４）で受けることができ、また防水性もより良好なものとなる。It is preferable that the roof material 30 with the recess has load receiving portions 34 on which the roof material 101 can abut on both sides of the girder with the recess 31 interposed therebetween. The recess 31 is partially formed, for example, in the vicinity of the center in the spar direction of the ridge side portion that overlaps the roof material 101. For example, the width W 31 of the recess 31 is set to about 1.1 to 1.5 times the width W 27 of the intermediate portion 27. In this case, the load of the roofing material 101 can be received by the upper surface (the load receiving portion 34) of the roofing material 30 with a recess while maintaining excellent workability, and the waterproofness is also improved.

凹部付き屋根材３０は、凹部３１の直下に位置する下面から突出した脚部３５を有することが好適である。脚部３５は、例えば、野地板１０３に当接する程度の突出長さを有する。脚部３５を設けることで、金具２０を介して凹部３１の上面に大きな荷重が加わった場合でも当該荷重を野地板１０３に逃がすことができる。これにより、垂れ部３３と略接触する軒側の屋根材１０１に大きな荷重が加わらないようにし、当該屋根材の破損を防止できる。   It is preferable that the roof material 30 with a recess has a leg portion 35 that protrudes from the lower surface located immediately below the recess 31. For example, the leg portion 35 has a protruding length enough to contact the base plate 103. By providing the leg portion 35, even when a large load is applied to the upper surface of the recess 31 through the metal fitting 20, the load can be released to the field board 103. Accordingly, it is possible to prevent a large load from being applied to the eaves-side roof material 101 that is substantially in contact with the hanging portion 33 and to prevent the roof material from being damaged.

脚部３５は、金具２０の第２固定部２２の直下に位置することが好ましい。これにより、金具２０から伝わる荷重を効率良く受容できる。脚部３５の個数は特に限定されないが、好ましくは凹部３１の幅方向両側に２つの脚部３５を設ける。また、脚部３５の突出長さを棟側から軒側に向かって次第に長くし、脚部３５の野地板１０３に当接する面（下面）を野地板１０３に合わせて傾斜させることが好ましい。これにより、脚部３５の安定性が高まる。   The leg portion 35 is preferably located immediately below the second fixing portion 22 of the metal fitting 20. Thereby, the load transmitted from the metal fitting 20 can be received efficiently. The number of the leg portions 35 is not particularly limited, but preferably two leg portions 35 are provided on both sides of the concave portion 31 in the width direction. In addition, it is preferable that the protruding length of the leg portion 35 is gradually increased from the ridge side toward the eave side, and the surface (lower surface) of the leg portion 35 that contacts the base plate 103 is inclined according to the base plate 103. Thereby, the stability of the leg part 35 increases.

以上のように、取り付け器具１２によれば、金具２０が凹部付き屋根材３０の上面に形成された凹部３１に収容される。このため、金具２０の上に配置される屋根材１０１が金具２０によって押し上げられることがなく、屋根材１０１を施工時に加工する必要がない。したがって、取り付け器具１２を用いた太陽電池モジュール１１の取り付けは、施工が容易であり作業負荷の軽減に寄与する。   As described above, according to the attachment tool 12, the metal fitting 20 is accommodated in the concave portion 31 formed on the upper surface of the roof material 30 with the concave portion. For this reason, the roof material 101 arrange | positioned on the metal fitting 20 is not pushed up by the metal fitting 20, and it is not necessary to process the roof material 101 at the time of construction. Therefore, the attachment of the solar cell module 11 using the attachment device 12 is easy to construct and contributes to the reduction of the work load.
