軒棟方向に隣り合う横葺屋根材３は、軒側の横葺屋根材３の棟側接続部３２に対し、棟側の横葺屋根材３の軒側接続部３３が接続される。本実施形態では、屋根下地２の軒先の上面に横葺屋根材３を固定した上で、棟方向に隣接する横葺屋根材３を接続する。この棟方向に隣接する横葺屋根材３に対して、さらに棟方向に隣接する横葺屋根材３を接続する。つまり、本実施形態に係る屋根は、軒棟方向に隣り合う横葺屋根材３の接続関係が、屋根全面にわたって適用される。   The eaves-side connection 33 of the lateral roofing material 3 on the ridge side is connected to the lateral-side connection 32 of the lateral surface 3 on the eaves side. In this embodiment, after fixing the horizontal roof material 3 to the upper surface of the eaves tip of the roof base 2, the horizontal roof material 3 adjacent in the ridge direction is connected. The transverse roof material 3 adjacent to the ridge direction is connected to the transverse roof material 3 adjacent to the ridge direction. That is, as for the roof which concerns on this embodiment, the connection relation of the transverse roof material 3 which adjoins in the eaves-building direction is applied over the whole roof surface.

横葺屋根材３には、横方向にも別の横葺屋根材３が接続される。横方向に隣り合う横葺屋根材３は、図２Ｂ，２Ｃに示すように、横方向の端部同士が重なるように接続される。本実施形態では、横方向に隣り合う横葺屋根材３の接続部分を、「重なり部分３５」という場合がある。   Another traverse roof material 3 is connected to the traverse roof material 3 also in the lateral direction. As shown in FIGS. 2B and 2C, transversely adjacent transversely-arranged roofing roof members 3 are connected such that the lateral end portions overlap each other. In the present embodiment, the connecting portion of the horizontally adjacent roof coverings 3 may be referred to as “overlapping portion 35”.

重なり部分３５は、横方向に隣り合う横葺屋根材３のうちの一方の横葺屋根材３において、他方の横葺屋根材３側の端部（以下、第１端部３７）と、他方の横葺屋根材３において一方の横葺屋根材３側の端部（以下、第２端部３８）とが重なる部分である。第１端部３７は、第２端部３８の下方に重なる部分であり、横葺屋根材３の横方向の先端から横葺屋根材３の中央に向かう一定の寸法の範囲をいう。第２端部３８は、第１端部３７の上面に重なる部分であり、横葺屋根材３の横方向の先端から横葺屋根材３の中央に向かう一定の寸法の範囲をいう。   In the overlapping roof material 3 of the horizontal roof materials 3 adjacent to each other in the overlapping direction, the overlapping portion 35 is an end on the other horizontal roof material 3 side (hereinafter, the first end 37) and the other It is a part with which the edge part (the following, 2nd edge part 38) at the side of one covering roof material 3 in the covering roof material 3 of 3 overlaps. The first end portion 37 is a portion overlapping below the second end portion 38, and refers to a range of a certain dimension from the lateral end of the transverse roof material 3 to the center of the transverse roof material 3. The second end 38 is a portion overlapping the upper surface of the first end 37, and refers to a range of a certain dimension from the lateral end of the cross roof 3 to the center of the cross roof 3.

なお、この重なり部分３５の横方向の寸法は、特に限らない。また、「重なり部分３５」として、横葺屋根材３のうちの本体部３１のみが重なった場合であってもよいし、本体部３１，棟側接続部３２，軒側接続部３３及び取付部３４のすべてが重なった場合であってもよい。本実施形態では、重なり部分３５は、隣り合う横葺屋根材３の本体部３１，棟側接続部３２，軒側接続部３３，取付部３４が互いに重なって形成されている。   Note that the lateral dimension of the overlapping portion 35 is not particularly limited. Moreover, it may be a case where only the main body portion 31 of the horizontal roof material 3 overlaps as the "overlap portion 35", or the main body portion 31, the ridge side connection portion 32, the eaves side connection portion 33 and the attachment portion It may be the case where all 34 overlap. In the present embodiment, in the overlapping portion 35, the main body portion 31, the ridge side connecting portion 32, the eaves side connecting portion 33, and the attaching portion 34 of the adjacent roof covering material 3 are formed to overlap with each other.

重なり部分３５には、継ぎ目３６が含まれる。本実施形態における継ぎ目３６は、重なり部分３５において、上側の横葺屋根材３の端部（つまり第２端部３８）の縁と、第１端部３７の上面のうちの縁に対向する部分とでなす。   The overlapping portion 35 includes a seam 36. The joint 36 in the present embodiment is a portion facing the edge of the end (that is, the second end 38) of the upper cross-section roof 3 and the upper surface of the first end 37 in the overlapping portion 35. Serve with.

ところで、屋根面に沿って風が吹くと、屋根面の上方に負圧が生じ、屋根面に上方向の力が掛かるときがある。すると、重なり部分３５における第２端部３８が上方向に持ち上がることが懸念される。このため、本実施形態に係る横葺屋根構造１は、この継ぎ目３６をカバーするカバー部材４を備えており、これによって、継ぎ目３６の変形を抑えることができる。   By the way, when the wind blows along the roof surface, negative pressure may be generated above the roof surface, and an upward force may be applied to the roof surface. Then, there is a concern that the second end 38 of the overlapping portion 35 may be lifted upward. For this reason, the cocoon roof structure 1 according to the present embodiment is provided with the cover member 4 that covers the joint 36, whereby the deformation of the joint 36 can be suppressed.

カバー部材４は、カバー部材４自体が剛性を有することで、重なり部分３５を補強する機能を有する。これによって、重なり部分３５に上方向に力が掛かっても、重なり部分３５が変形するのをさらに抑えることができる。カバー部材４は、図３Ａに示すように、カバー部４１と、軒側保持部４２と、棟側保持部４３と、止水材４４とを備えている。   The cover member 4 has a function of reinforcing the overlapping portion 35 by the cover member 4 itself having rigidity. This can further suppress deformation of the overlapping portion 35 even if a force is applied upward to the overlapping portion 35. The cover member 4 is provided with the cover part 41, the eaves side holding part 42, the ridge side holding part 43, and the water stop material 44, as shown to FIG. 3A.

カバー部４１は、横葺屋根材３の接続部の継ぎ目３６を上方からカバーする（覆う）。カバー部４１は、本実施形態では、平面視矩形状に形成されており、横葺屋根材３の本体部３１の上面に重なる。カバー部４１は、幅方向が左右方向に平行であり、長さ方向が軒棟方向に平行である。カバー部４１の幅方向の両端部のそれぞれには、曲げ部４１１が形成されている。   The cover portion 41 covers (covers) the joint 36 of the connection portion of the traverse roof material 3 from above. In the present embodiment, the cover portion 41 is formed in a rectangular shape in plan view, and overlaps the upper surface of the main body portion 31 of the traverse roof material 3. The cover portion 41 has a width direction parallel to the left and right direction, and a length direction parallel to the eaves ridge direction. Bent portions 411 are formed at both end portions of the cover portion 41 in the width direction.

一対の曲げ部４１１は、継ぎ目３６に対して、左右方向の一方側に位置する横葺屋根材３の上面と、他方側に位置する横葺屋根材３の上面とにそれぞれ対向する。本実施形態では、各曲げ部４１１は、横葺屋根材３の上面に当たる。各曲げ部４１１は、カバー部４１の横方向の先端を下方向に曲げることで形成された部分である。各曲げ部４１１は、カバー部４１の幅方向の両端に位置する部分であり、カバー部４１のうち、中央部分よりも下方に位置する部分である。各曲げ部４１１は、縁に向かうほど下方に位置するように傾斜した傾板４１２と、傾板４１２の先端から横方向に延びた横板４１３とを備えている。曲げ部４１１が設けられていることで、カバー部４１の剛性が高くなる。この結果、重なり部分３５の剛性が高くなり、継ぎ目３６が開くのを抑えることができる。   The pair of bent portions 411 respectively oppose the upper surface of the transverse roof material 3 located on one side in the left-right direction and the upper surface of the transverse roof material 3 located on the other side with respect to the joint 36. In the present embodiment, each bent portion 411 hits the upper surface of the covering roof material 3. Each bent portion 411 is a portion formed by bending the tip end of the cover portion 41 in the downward direction.
