Description

本発明は、屋根構造に関する。 The present invention relates to a roof structure.

建造物の野地板上にスレート等の屋根材が設けられた屋根構造が知られている（例えば特許文献１参照）。この屋根構造では、野地板と屋根材との間の通気性が良くないという問題がある。そこで、凸部と凹部とを軒方向に交互に有する凹凸屋根材を用い、この凹凸屋根材を野地板上に設置して、凸部と野地板との間に通気空間を形成することが考えられた。この場合、その固定手段として、凹凸屋根材が有する凹部の底面を野地板に対してネジ、釘等で固定するという手段が考えられる。この手段によれば、野地板に対して凹凸屋根材を強固に固定することができるが、その一方で、水仕舞い等の面で問題が生じる。 A roof structure in which a roof material such as a slate is provided on a field plate of a building is known (see, for example, Patent Document 1). This roof structure has a problem that the air permeability between the base plate and the roofing material is not good. Therefore, it is considered to use an uneven roof material having convex portions and concave portions alternately in the eave direction, and install the uneven roof material on the base plate to form a ventilation space between the convex portion and the base plate. It was. In this case, as the fixing means, a means of fixing the bottom surface of the concave portion of the uneven roof material to the base plate with screws, nails or the like can be considered. According to this means, it is possible to firmly fix the uneven roof material to the base plate, but on the other hand, there arises a problem in terms of water performance.

本発明を、添付図面に示す実施形態に基づいて説明する。図１〜図５には、本発明の一実施形態の屋根構造を示している。図６〜図８には、本実施形態の屋根構造の凹凸屋根材１１を野地板４に固定するための構造や手順を示している。 The present invention will be described based on embodiments shown in the accompanying drawings. 1 to 5 show a roof structure according to an embodiment of the present invention. 6 to 8 show a structure and a procedure for fixing the uneven roof material 11 of the roof structure of the present embodiment to the field board 4.

まず、本実施形態の屋根構造について説明する。本実施形態の屋根構造は、図２に示す片流れ屋根を有する建物１に適用したものである。 First, the roof structure of this embodiment will be described. The roof structure of this embodiment is applied to the building 1 having a single-flow roof shown in FIG.

以下の本文中では、傾斜した屋根面に沿って軒と棟を結ぶ方向を軒棟方向Ｄ１とし、軒に沿う方向を軒方向Ｄ２とし、棟に沿う方向を棟方向Ｄ３とする。本実施形態では、軒方向Ｄ２と棟方向Ｄ３は平行である。 In the following text, the direction connecting the eaves and ridges along the inclined roof surface is defined as the eave building direction D1, the direction along the eaves is defined as the eave direction D2, and the direction along the ridge is defined as the building direction D3. In this embodiment, the eaves direction D2 and the ridge direction D3 are parallel.

図１に示すように、建物１の軒側の外壁の上端部には、屋外側に向かって突出する軒部２が形成されている。軒部２の屋外側の面（鼻板面）は下方ほど屋内側に位置するように傾斜している。また、図４に示すように、建物１の棟側の外壁の上端部には、屋外側に向かって突出する棟部３が形成されている。棟部３の屋外側の面は鉛直である。 As shown in FIG. 1, the eaves part 2 which protrudes toward the outdoor side is formed in the upper end part of the outer wall of the eaves side of the building 1. The surface of the eaves part 2 on the outdoor side (nose plate surface) is inclined so as to be located on the indoor side as it goes downward. Moreover, as shown in FIG. 4, the ridge part 3 which protrudes toward the outdoor side is formed in the upper end part of the outer wall on the ridge side of the building 1. The surface of the ridge 3 on the outdoor side is vertical.

建物１の屋根下地は、垂木等の建築躯体上に野地板４を設けることで形成されている。野地板４は棟側から軒側に向かって一様な角度で下り傾斜している。図１に示すように、野地板４の軒側端部は軒部２よりもさらに屋外側に突出している。野地板４の軒側端面は軒部２の屋外側の面と略平行である。図４に示すように、野地板４の棟側端部は、軒棟方向Ｄ１において棟部３の屋外側の面よりも屋内側に控えた位置に配置されている。 The roof base of the building 1 is formed by providing a base plate 4 on an architectural frame such as a rafter. The field board 4 is inclined downward at a uniform angle from the building side to the eaves side. As shown in FIG. 1, the eaves side end of the field board 4 protrudes further to the outdoor side than the eaves 2. The eaves side end face of the base plate 4 is substantially parallel to the outdoor side face of the eaves part 2. As shown in FIG. 4, the ridge side end of the field board 4 is disposed at a position that is further on the indoor side than the surface on the outdoor side of the ridge 3 in the eaves ridge direction D1.

図１、図６に示すように野地板４の軒側の端部上には、固定部材６が載置されて固定される。これにあたり、本実施形態では、まず野地板４の軒側の端部上に、軒方向Ｄ２の略全長に亘って軒側後誘導板５が載置され、軒側後誘導板５の上に、板状をした固定部材６が軒方向Ｄ２の略全長に亘って載置されている。軒側後誘導板５及び固定部材６は鋼板製である。軒側後誘導板５や固定部材６は軒方向Ｄ２に複数並べて設けた部材で構成してもよいし、軒方向Ｄ２に亘って一体に形成したものであってもよいし、板状をしたものでなくてもよい。 As shown in FIGS. 1 and 6, a fixing member 6 is placed and fixed on the end of the eaves side of the base plate 4. In this case, in this embodiment, first, the eaves side rear guide plate 5 is placed on the eaves side end portion of the base plate 4 over substantially the entire length of the eave direction D2, and the eaves side rear guide plate 5 is placed on the eaves side rear guide plate 5. The plate-like fixing member 6 is placed over substantially the entire length of the eaves direction D2. The eaves side rear guide plate 5 and the fixing member 6 are made of steel plates. The eaves side rear guide plate 5 and the fixing member 6 may be constituted by a plurality of members arranged side by side in the eave direction D2, may be integrally formed over the eave direction D2, or have a plate shape. It doesn't have to be a thing.

固定部材６には面戸取付部２８が設けられる。面戸取付部２８は、図６に示すように、固定部材６において、軒方向Ｄ２に間隔を介して複数形成されている。各面戸取付部２８は、対応する凸部１２の軒側の端部の開口（後述する通気空間１７の端部の開口）を略閉塞するように配置されるのが好ましいが、前記開口より小さくても構わない。固定部材６については後述する。 The fixed member 6 is provided with a face door mounting portion 28. As shown in FIG. 6, a plurality of face door attachment portions 28 are formed in the eaves direction D <b> 2 with a space in the fixing member 6. Each face door mounting portion 28 is preferably arranged so as to substantially close an opening at an eave side end of the corresponding convex portion 12 (opening at an end portion of a ventilation space 17 to be described later). It can be small. The fixing member 6 will be described later.

図４に示すように、野地板４の棟側の端部上面には、棟側誘導板７が棟方向Ｄ３の略全長に亘って載置されている。棟側誘導板７は棟方向Ｄ３に複数並べて設けた部材で構成してもよいし、棟方向Ｄ３に亘って一体に形成したものであってもよい。 As shown in FIG. 4, the ridge-side guide plate 7 is placed on the upper surface of the end of the base plate 4 on the ridge side over substantially the entire length in the ridge direction D3. The ridge-side guide plate 7 may be composed of a plurality of members arranged side by side in the ridge direction D3, or may be integrally formed across the ridge direction D3.

野地板４の上には、図２に示すように、凹凸屋根材１１が軒方向Ｄ２に複数並べて載置されている。各凹凸屋根材１１は鋼板製である。各凹凸屋根材１１は、下方に開口し且つ上方に突出する凸部１２と、上方に開口し且つ下方に凹む凹部１３とを、軒方向Ｄ２に交互に形成したものである。各凸部１２の側面部は、隣接する凹部１３の側面部を兼ねている。各凸部１２の両側面部は上面部に対して略直角である。 As shown in FIG. 2, a plurality of uneven roof materials 11 are placed side by side in the eave direction D2 on the base plate 4. Each uneven roof material 11 is made of a steel plate. Each uneven roof material 11 is formed by alternately forming convex portions 12 that open downward and protrude upward, and concave portions 13 that open upward and recessed downward in the eave direction D2. The side surface portion of each convex portion 12 also serves as the side surface portion of the adjacent concave portion 13. Both side surface portions of each convex portion 12 are substantially perpendicular to the upper surface portion.

各凹凸屋根材１１の軒側部分は、図１に示すように、固定部材６及び軒側後誘導板５を介して、野地板４上に載置される。また、図４に示すように、各凹凸屋根材１１の棟側部分は、棟側誘導板７を介して野地板４上に載置される。 As shown in FIG. 1, the eaves side portion of each uneven roof material 11 is placed on the field board 4 through the fixing member 6 and the eaves side rear guide plate 5. As shown in FIG. 4, the ridge side portion of each uneven roof material 11 is placed on the field board 4 via the ridge side guide plate 7.

図３に示すように、凹凸屋根材１１側の端部には凹部１３が形成されており、この凹部１３の外側面部の上部に、被掛止部１４が形成されている。隣り合う凹凸屋根材１１の間には、連結具８が配置されており、連結具８が有する掛止部１０に対して凹凸屋根材１１の被掛止部１４が掛止される。 As shown in FIG. 3, a concave portion 13 is formed at an end portion on the uneven roof material 11 side, and a hooked portion 14 is formed at an upper portion of the outer surface portion of the concave portion 13. A connecting tool 8 is disposed between the adjacent uneven roof materials 11, and the hooked portion 14 of the uneven roof material 11 is hooked to the hooking portion 10 of the connecting tool 8.

各連結具８には、軒棟方向Ｄ１に長いカバー部材１５が取り付けられる（図９参照）。各カバー部材１５は、図３に示すように、下方に開口する略溝形の部材であり、その両側面部の下部には、被係合部１６が形成されている。各カバー部材１５の両側の被係合部１６が、対応する凹凸屋根材１１の被掛止部１４に掛止されることにより、各カバー部材１５は、両側の凹凸屋根材１１を介して連結具８に取り付けられる。カバー部材１５は、両側の凹凸屋根材１１の間の部分と、ここに配置された連結具８を、上側から覆うものである。 A long cover member 15 is attached to each connector 8 in the eaves-ridge direction D1 (see FIG. 9). As shown in FIG. 3, each cover member 15 is a substantially groove-shaped member that opens downward, and an engaged portion 16 is formed at a lower portion of both side surface portions. The engaged portions 16 on both sides of each cover member 15 are hooked on the corresponding latched portions 14 of the uneven roof material 11 so that each cover member 15 is connected via the uneven roof material 11 on both sides. It is attached to the tool 8. The cover member 15 covers the part between the uneven roof materials 11 on both sides and the connector 8 arranged here from above.

図１、図６に示すように、野地板４とこの上に配置された各凹凸屋根材１１の間には、通気空間１７が形成されている。各通気空間１７は、凸部１２と野地板４で囲まれた空間であり、軒方向Ｄ２に沿って凸部１２と同数形成されている。通気空間１７は、軒棟方向Ｄ１と直交する断面において、断面矩形状となるように形成されており、凹凸屋根材１１の軒棟方向Ｄ１の全長に亘って形成されている。 As shown in FIGS. 1 and 6, a ventilation space 17 is formed between the base plate 4 and each of the uneven roof materials 11 disposed thereon. Each ventilation space 17 is a space surrounded by the convex portion 12 and the base plate 4, and is formed in the same number as the convex portion 12 along the eaves direction D2. The ventilation space 17 is formed to have a rectangular cross section in a cross section perpendicular to the eave building direction D1, and is formed over the entire length of the uneven roof material 11 in the eave building direction D1.

凹凸屋根材１１の軒側端部は、軒棟方向Ｄ１において野地板４の軒側端縁よりも屋外側に位置した出代部１８となっている。凹凸屋根材１１の出代部１８における凸部１２（すなわち、各凸部１２の軒側の端部）は、下方に開口している。これら出代部１８における各凸部１２の下開口は、軒棟方向Ｄ１に長い矩形状に形成されており、この下開口部分が、対応する通気空間１７の導入口１９（図５参照）を構成している。 The eaves-side end of the uneven roofing material 11 is a margin 18 that is located on the outdoor side of the eaves-side end edge of the base plate 4 in the eaves-ridge direction D1. The convex part 12 (namely, the edge part of the eaves side of each convex part 12) in the allowance part 18 of the uneven roof material 11 is opened below. The lower opening of each convex portion 12 in the outlet portion 18 is formed in a rectangular shape that is long in the eaves-ridge direction D1, and this lower opening portion serves as the inlet 19 (see FIG. 5) of the corresponding ventilation space 17. It is composed.

図１や図４に示すように、軒側後誘導板５、固定部材６、及び棟側誘導板７は、対応する凹凸屋根材１１と野地板４の間に挟み込まれた状態で、野地板４に対して固定されている。 As shown in FIGS. 1 and 4, the eaves side rear guide plate 5, the fixing member 6, and the ridge side guide plate 7 are sandwiched between the corresponding uneven roof material 11 and the field plate 4, and the field plate 4 is fixed.

図１に示すように、軒側後誘導板５の軒側端縁には、野地板４の軒側端面に沿って下側に突出する板状の後誘導部２０が形成されている。後誘導部２０は、軒側後誘導板５の軒方向Ｄ２の全長に亘って形成されている。後誘導部２０の下端部は、野地板４の軒側端面よりも下側に突出している。この突出部分の下部は、屋外側に屈曲した屈曲部分２１とな
っている。屈曲部分２１は水切として機能する。 As shown in FIG. 1, a plate-shaped rear guiding portion 20 that protrudes downward along the eaves side end surface of the field plate 4 is formed at the eaves side edge of the eaves side rear guiding plate 5. The rear guiding portion 20 is formed over the entire length of the eaves direction rear guiding plate 5 in the eave direction D2. The lower end portion of the rear guiding portion 20 protrudes below the eaves side end surface of the field plate 4. A lower portion of the protruding portion is a bent portion 21 bent outward. The bent portion 21 functions as a drainer.

固定部材６の棟側部分は、野地板４の軒側の端部上に（本実施形態では軒側後誘導板５を介して）載置される基部６０となる。固定部材６の基部６０よりも軒側（外方）部分は、軒棟方向Ｄ１において軒側後誘導板５よりも屋外側に向かって突出している。この突出部分がカバー部２２を構成し、各凹凸屋根材１１の出代部１８の下側において、導入口１９を覆うように配置されている。カバー部２２において各導入口１９と重なる部分には、連通口２４（図１、図６〜図８参照）が形成されている。このように、連通口２４を有するカバー部２２を導入口１９に設けることで、通気空間１７に雨水や小鳥、虫等が入り込み難くなる。 The ridge side portion of the fixing member 6 serves as a base portion 60 that is placed on the eaves side end portion of the base plate 4 (in this embodiment, via the eaves side rear guide plate 5). The eaves side (outward) portion of the fixing member 6 from the base portion 60 protrudes toward the outdoor side from the eaves side rear guide plate 5 in the eave building direction D1. This projecting portion constitutes the cover portion 22 and is disposed so as to cover the introduction port 19 below the protruding portion 18 of each uneven roof material 11. A communication port 24 (see FIGS. 1 and 6 to 8) is formed at a portion of the cover portion 22 that overlaps each introduction port 19. Thus, by providing the cover portion 22 having the communication port 24 in the introduction port 19, rainwater, small birds, insects, and the like are less likely to enter the ventilation space 17.

カバー部２２の軒側端部には、屈曲部分２１と略平行となるように、板状の縁片部２５が下方にむけて突設されている。縁片部２５の屋外側の面は、軒棟方向Ｄ１において、凹凸屋根材１１の軒側端面と略同じ位置に配置されている。 A plate-like edge piece 25 is provided at the eaves side end of the cover portion 22 so as to protrude downward so as to be substantially parallel to the bent portion 21. The surface on the outdoor side of the edge piece 25 is disposed at substantially the same position as the eaves-side end surface of the uneven roof material 11 in the eave building direction D1.

本実施形態においては、図６〜図８に示すように平板状をした固定部材６が折曲されることで、カバー部２２と縁片部２５とが形成される。そして、カバー部２２の一部が切り起こされて、切り起こされた跡に連通口２４が形成され、切り起こされた面戸取付部２８が基部６０から起立している。 In this embodiment, the cover part 22 and the edge piece part 25 are formed when the fixing member 6 having a flat plate shape is bent as shown in FIGS. Then, a part of the cover portion 22 is cut and raised, the communication port 24 is formed in the cut and raised mark, and the cut and raised face door mounting portion 28 stands from the base portion 60.

縁片部２５は屈曲部分２１に対向しており、図１に示すように、縁片部２５と屈曲部分２１の間に空間２９が形成されている。空間２９は、下側に開口し且つ連通口２４を介して通気空間１７に連通するスペースである。縁片部２５の下端部は、水切として機能する。 The edge piece portion 25 faces the bent portion 21, and a space 29 is formed between the edge piece portion 25 and the bent portion 21 as shown in FIG. 1. The space 29 is a space that opens downward and communicates with the ventilation space 17 through the communication port 24. The lower end portion of the edge piece portion 25 functions as a drainer.

屋外の空気は、縁片部２５と屈曲部分２１の間の空間２９及び連通口２４（導入口１９）を順に経て、各通気空間１７に導入されるようになっている。この場合、空間２９に下側から入り込んだ空気は、屈曲部分２１および後誘導部２０の屋外側の面と、縁片部２５の屋内側の面およびカバー部２２の下面に沿って上昇し、連通口２４（導入口１９）にまで誘導される。連通口２４を通じて通気空間１７にまで導入された空気は、通気空間１７の棟側の端部開口である後述の導出口３２から排出される。これにより、野地板４と凹凸屋根材１１の間において、良好な通気性が確保される。 Outdoor air is introduced into each ventilation space 17 through the space 29 between the edge piece 25 and the bent portion 21 and the communication port 24 (introduction port 19) in this order. In this case, the air that has entered the space 29 from the lower side rises along the outdoor side surface of the bent portion 21 and the rear guiding portion 20, the indoor side surface of the edge piece portion 25, and the lower surface of the cover portion 22, It is guided to the communication port 24 (introduction port 19). The air introduced to the ventilation space 17 through the communication port 24 is discharged from a later-described outlet 32 that is an end opening on the ridge side of the ventilation space 17. Thereby, favorable air permeability is ensured between the field board 4 and the uneven roofing material 11.

図２、図５に示すように、軒部２の屋外側には、軒部２に沿って軒樋３１が設けられている。軒樋３１は、各凹凸屋根材１１の上面から屋外側に流出した雨水を受ける位置に設置されている。より具体的に述べると、この軒樋３１は、各通気空間１７の導入口１９、屈曲部分２１の下端部、及び、縁片部２５の下端部の、夫々の下方に位置するように設置されている。これにより、各通気空間１７に雨水が浸入した場合に、カバー部２２の連通口２４から排出された雨水を、軒樋３１で受けることができる。また、屈曲部分２１の下端部や縁片部２５の下端部から落下した雨水を、軒樋３１で受けることができる。 As shown in FIGS. 2 and 5, an eaves basket 31 is provided along the eaves part 2 on the outdoor side of the eaves part 2. The eaves 31 is installed at a position for receiving rainwater that flows out from the upper surface of each uneven roofing material 11 to the outdoor side. More specifically, the eaves bowl 31 is installed so as to be located below the inlet 19 of each ventilation space 17, the lower end of the bent portion 21, and the lower end of the edge piece 25. ing. Thereby, when rainwater enters each ventilation space 17, rainwater discharged from the communication port 24 of the cover portion 22 can be received by the eaves 31. In addition, rainwater that has dropped from the lower end of the bent portion 21 and the lower end of the edge piece 25 can be received by the eaves basket 31.

他方、各凹凸屋根材１１の棟側端部は、図４に示すように野地板４の棟側端面よりも軒
側に控えた位置に配置されている。凹凸屋根材１１の凸部１２の棟側端部と野地板４で囲まれた開口により、通気空間１７の導出口３２が構成されている。各通気空間１７の導出口３２は、野地板４上で棟側に向けて開口している。 On the other hand, the ridge side end of each uneven roofing material 11 is disposed at a position that is further on the eaves side than the ridge side end surface of the base plate 4 as shown in FIG. The outlet 32 of the ventilation space 17 is constituted by the ridge side end of the convex portion 12 of the uneven roof material 11 and the opening surrounded by the base plate 4. The outlet 32 of each ventilation space 17 opens toward the ridge side on the field board 4.

棟側誘導板７の棟側部分は、凹凸屋根材１１よりも棟側に突出しており、この突出部分が誘導部３３を構成する。誘導部３３の棟側部分は、上側に折り曲げられた折曲部分３４となっており、この折曲部分３４は通気空間１７の導出口３２に対向して位置する。折曲部分３４の突出方向は、野地板４に対して直交する方向よりも棟側に傾けられており、この傾斜によって、各通気空間１７から排出された空気は棟側に流れやすくなっている。 The ridge side portion of the ridge side guide plate 7 protrudes toward the ridge side with respect to the uneven roof material 11, and this protruding portion constitutes the guide portion 33. The ridge side portion of the guide portion 33 is a bent portion 34 that is bent upward, and the bent portion 34 is positioned to face the outlet 32 of the ventilation space 17. The protruding direction of the bent portion 34 is inclined to the ridge side with respect to the direction orthogonal to the base plate 4, and the air discharged from each ventilation space 17 easily flows to the ridge side by this inclination. .

棟部３には、野地板４の棟方向Ｄ３に亘る棟部カバー３６が取り付けられている。棟部カバー３６は、棟方向Ｄ３に複数並べて設けた部材で構成してもよいし、棟方向Ｄ３に亘って一体に形成したものであってもよい。 A ridge cover 36 extending in the ridge direction D3 of the field board 4 is attached to the ridge 3. The ridge part cover 36 may be composed of a plurality of members arranged side by side in the ridge direction D3, or may be integrally formed across the ridge direction D3.

棟部カバー３６は、棟部３との間に隙間が形成されるように、複数の取付具３７を介して棟部３に取り付けられている。棟部カバー３６は、屋外側の面を構成する縦板部３８と、上面を構成する横板部３９と、側端面を構成する側板部４０（図２参照）を備えている。 The ridge part cover 36 is attached to the ridge part 3 via a plurality of fixtures 37 so that a gap is formed between the ridge part 3 and the ridge part 3. The ridge cover 36 includes a vertical plate portion 38 that forms an outdoor surface, a horizontal plate portion 39 that forms an upper surface, and a side plate portion 40 (see FIG. 2) that forms a side end surface.

横板部３９は、縦板部３８の上端部から軒側に向けて突出し、軒棟方向Ｄ１と略平行である。横板部３９は、野地板４、凹凸屋根材１１及び棟側誘導板７の上方に配置されている。横板部３９と誘導部３３の間には、各導出口３２に連通する空間４１が形成されている。横板部３９と凹凸屋根材１１の間には、空間４１の軒側に連通する空間４２が形成されている。横板部３９の軒側端部には、下側に向けて突出する突片部４３が、棟方向Ｄ３に亘って形成されている。突片部４３の下端部と、この下側に位置する凹凸屋根材１１の間には、開口４４が形成されている。空間４２は、開口４４を介して軒側に向けて開口している。すなわち、各通気空間１７の導出口３２は、凹凸屋根材１１の棟側端部近傍に位置する空間４１及び空間４２を介して、開口４４に連通している。 The horizontal plate portion 39 protrudes from the upper end portion of the vertical plate portion 38 toward the eaves side, and is substantially parallel to the eaves-ridge direction D1. The horizontal plate portion 39 is disposed above the field plate 4, the uneven roof material 11, and the ridge side guide plate 7. A space 41 communicating with each outlet 32 is formed between the horizontal plate portion 39 and the guide portion 33. A space 42 communicating with the eaves side of the space 41 is formed between the horizontal plate portion 39 and the uneven roof material 11. A protruding piece 43 that protrudes downward is formed at the eaves side end of the horizontal plate portion 39 over the ridge direction D3. An opening 44 is formed between the lower end portion of the projecting piece portion 43 and the uneven roof material 11 located on the lower side. The space 42 opens toward the eaves side through the opening 44. That is, the outlet 32 of each ventilation space 17 communicates with the opening 44 via the space 41 and the space 42 located in the vicinity of the ridge side end of the uneven roof material 11.

縦板部３８は、棟部３の屋外側の面と略平行である。縦板部３８と棟部３の間には、空間４１に連通する空間４５が形成されている。空間４５は、縦板部３８の下端部と棟部３の間に形成された通気口４６を介して下側に開口している。 The vertical plate portion 38 is substantially parallel to the outdoor side surface of the ridge portion 3. A space 45 communicating with the space 41 is formed between the vertical plate portion 38 and the ridge portion 3. The space 45 opens downward through a vent 46 formed between the lower end of the vertical plate portion 38 and the ridge 3.

図５（ａ）に示すように、軒側から棟側に矢印のように風が吹く場合、この風は屈曲部分２１で受けられて導入口１９側に導かれ、各通気空間１７内を軒側から棟側へと流れる。他方、風が棟側から軒側に向かって吹く場合、図５（ｂ）に示すように、風は矢印のように上方から軒樋３１内に吹き込まれて該軒樋３１の内面に沿って上昇し、屈曲部分２１に沿って導入口１９側に誘導され、各通気空間１７内を軒側から棟側へと流れる。即ち、通気空間１７において通常は、軒側から棟側に向かうように空気の流れが生じる。各通気空間１７の導出口３２から排出された空気は、空間４１、空間４５及び通気口４６を介して、棟部カバー３６の下側に排出される。 As shown in FIG. 5A, when the wind blows from the eave side to the ridge side as indicated by the arrow, the wind is received by the bent portion 21 and guided to the introduction port 19 side, and the inside of each ventilation space 17 is passed through the eaves. It flows from the side to the building side. On the other hand, when the wind blows from the building side toward the eaves side, the wind is blown into the eaves bowl 31 from above as shown by an arrow along the inner surface of the eaves bowl 31 as shown in FIG. It rises, is guided to the inlet 19 side along the bent portion 21, and flows in each ventilation space 17 from the eaves side to the ridge side. That is, in the ventilation space 17, an air flow usually occurs from the eaves side toward the ridge side. The air discharged from the outlet 32 of each ventilation space 17 is discharged to the lower side of the ridge cover 36 through the space 41, the space 45, and the ventilation hole 46.

ところで、図４の矢印ａ１に示すように棟側から軒側に向けて風が吹くと、この風は建物１の棟側の外壁面に当たった後、矢印ｂ１に示すように建物１の棟側の外壁面に沿って上昇し、この後、通気口４６から空間４５に導入される。空間４５に導入された空気は、空間４１及び空間４２を順に経て開口４４から排出される。このとき、凹凸屋根材１１の棟側端部近傍に位置する空間４１の上部では、空気の通過によって負圧が生じ、通気空間１７から空気を引き込むように作用する。この負圧により、各通気空間１７において軒側から棟側に向かう空気の流れが生じやすくなる。 By the way, when the wind blows from the building side toward the eave side as shown by the arrow a1 in FIG. 4, the wind hits the outer wall surface on the building side of the building 1 and then the building 1 of the building 1 as shown by the arrow b1. It rises along the outer wall surface on the side, and is then introduced into the space 45 from the vent 46. The air introduced into the space 45 is exhausted from the opening 44 through the space 41 and the space 42 in order. At this time, in the upper portion of the space 41 located in the vicinity of the ridge side end of the uneven roof material 11, a negative pressure is generated by the passage of air and acts to draw air from the ventilation space 17. Due to this negative pressure, an air flow from the eaves side toward the ridge side is likely to occur in each ventilation space 17.

本実施形態では、図２に示すように、複数の凹凸屋根材１１で構成される屋根面上に、機能パネルとしての太陽光発電パネル４８が設けられている。太陽光発電パネル４８は、シリコンを主材料とした半導体素子により太陽光エネルギーを電気エネルギーに変換して出力するものである。太陽光発電パネル４８は、上下両面で受光して発電可能な両面受光型のパネルであってもよいし、上面のみで受光して発電可能なパネルであってもよい。 In the present embodiment, as shown in FIG. 2, a photovoltaic power generation panel 48 as a functional panel is provided on a roof surface constituted by a plurality of uneven roof materials 11. The solar power generation panel 48 converts solar energy into electric energy and outputs it by a semiconductor element mainly made of silicon. The solar power generation panel 48 may be a double-sided light receiving panel that can receive power from both the upper and lower surfaces and generate power, or a panel that can receive light from only the upper surface and generate power.

図４に示すように、太陽光発電パネル４８の棟側端部は、棟部カバー３６の横板部３９の軒側端部の近傍に配置されている。太陽光発電パネル４８の棟側端面は、棟部カバー３６の突片部４３に対向し、突片部４３との間に空気導出用の間隙５３が形成される。 As shown in FIG. 4, the ridge side end portion of the photovoltaic power generation panel 48 is disposed in the vicinity of the eave side end portion of the horizontal plate portion 39 of the ridge portion cover 36. The ridge-side end surface of the photovoltaic power generation panel 48 faces the protruding piece 43 of the ridge cover 36, and an air derivation gap 53 is formed between the protruding piece 43.

凹凸屋根材１１同士を連結する任意の連結具８には、図３に示すように、カバー部材１５よりも上方に突出するボルト４９が設けられている。太陽光発電パネル４８は、これらボルト４９を用いて屋根面上に固定されている。 As shown in FIG. 3, the arbitrary connecting tool 8 that connects the uneven roof materials 11 is provided with a bolt 49 protruding upward from the cover member 15. The photovoltaic power generation panel 48 is fixed on the roof surface using these bolts 49.

図４に示すように、太陽光発電パネル４８は複数の凸部１２の上面に載置されており、複数の凸部１２に跨っている。このため、太陽光発電パネル４８とこの下方に位置する凹凸屋根材１１の間には、第二通気空間５２が形成されている。第二通気空間５２は、太陽光発電パネル４８と、凹凸屋根材１１の凹部１３で囲まれた空間であり、太陽光発電パネル４８で閉塞された凹部１３と同数だけ形成される。第二通気空間５２は、軒棟方向Ｄ１と直交する断面において断面矩形状となるように形成されている。第二通気空間５２は、太陽光発電パネル４８の軒棟方向Ｄ１における全長に亘って形成される。 As shown in FIG. 4, the photovoltaic power generation panel 48 is placed on the upper surfaces of the plurality of convex portions 12 and straddles the plurality of convex portions 12. For this reason, the 2nd ventilation space 52 is formed between the photovoltaic power generation panel 48 and the uneven | corrugated roofing material 11 located under this. The second ventilation space 52 is a space surrounded by the solar power generation panel 48 and the concave portion 13 of the uneven roof material 11, and is formed in the same number as the concave portions 13 closed by the solar power generation panel 48. The 2nd ventilation space 52 is formed so that it may become a cross-sectional rectangular shape in the cross section orthogonal to the eaves-ridge direction D1. The second ventilation space 52 is formed over the entire length of the photovoltaic power generation panel 48 in the eaves-ridge direction D1.

図２に示すように、第二通気空間５２の軒側の端部開口５０は、凹凸屋根材１１の軒棟方向Ｄ１における中央部付近に位置している。図４に示すように、第二通気空間５２の棟側の端部開口５１は、軒棟方向Ｄ１において棟部カバー３６の横板部３９よりもわずかに軒側に位置し、間隙５３及び開口４４に連通する。 As shown in FIG. 2, the end opening 50 on the eaves side of the second ventilation space 52 is located near the center in the eaves ridge direction D <b> 1 of the uneven roof material 11. As shown in FIG. 4, the end opening 51 on the ridge side of the second ventilation space 52 is located slightly on the eaves side with respect to the lateral plate portion 39 of the ridge cover 36 in the eave building direction D1, and the gap 53 and the opening 44.

第二通気空間５２では、軒側から棟側に向かって空気が流れやすくなっている。これは、軒側に向かって下り傾斜した凹凸屋根材１１に当たった風が、棟側に向かって流れやすいからである。第二通気空間５２の端部開口５１から排出された空気は、開口４４を経て、棟部カバー３６内の空間４２、空間４１、及び空間４５を順に通過し、この後、通気口４６から棟部カバー３６の下側に排出される。第二通気空間５２から排出された空気が空間４１の上部を通過するとき、この空間４１の上部において負圧が生じ、通気空間１７から空気を引き込むように作用する。このときの負圧によっても、各通気空間１７において軒側から棟側に向かう空気の流れが生じやすくなる。 In the second ventilation space 52, air easily flows from the eaves side toward the ridge side. This is because the wind hitting the uneven roofing material 11 inclined downward toward the eave side tends to flow toward the ridge side. The air exhausted from the end opening 51 of the second ventilation space 52 passes through the opening 42, the space 42, the space 41, and the space 45 in the ridge cover 36 in order, and then passes through the ventilation port 46. It is discharged to the lower side of the part cover 36. When the air discharged from the second ventilation space 52 passes through the upper portion of the space 41, a negative pressure is generated in the upper portion of the space 41, and the air is drawn from the ventilation space 17. The negative pressure at this time also tends to cause an air flow from the eave side to the building side in each ventilation space 17.

ところで、太陽光発電パネル４８は、周囲の雰囲気温度が高い場合や、直射日光が長時間照射された場合等に、発電素子が高温になって発電効率（変換効率）が低下する恐れがある。しかし、本実施形態では、前記のように太陽光発電パネル４８の下方に通気空間１７と第二通気空間５２を設けたことで、通気空間１７や第二通気空間５２を流れる空気により太陽光発電パネル４８を冷却し、太陽光発電パネル４８の温度上昇を抑えることができる。したがって、太陽光発電パネル４８の発電効率の低下が抑制される。 By the way, the photovoltaic power generation panel 48 has a possibility that the power generation element becomes high temperature and the power generation efficiency (conversion efficiency) is lowered when the ambient temperature is high or when direct sunlight is irradiated for a long time. However, in this embodiment, by providing the ventilation space 17 and the second ventilation space 52 below the photovoltaic power generation panel 48 as described above, the photovoltaic power generation is performed by the air flowing through the ventilation space 17 and the second ventilation space 52. The panel 48 can be cooled and the temperature rise of the photovoltaic power generation panel 48 can be suppressed. Therefore, a decrease in power generation efficiency of the solar power generation panel 48 is suppressed.

以下においては、凹凸屋根材１１を野地板４に固定するための構造や手順について、図６〜図８に基づいて詳述する。 Below, the structure and procedure for fixing the uneven roof material 11 to the field board 4 are explained in full detail based on FIGS.

上述したように、固定部材６には、凹凸屋根材１１が有する複数の凸部１２と一対一で対応するように、複数の面戸取付部２８を上方に突出させて設けている。 As described above, the fixed member 6 is provided with the plurality of face door mounting portions 28 protruding upward so as to correspond one-to-one with the plurality of convex portions 12 of the uneven roof material 11.

一方、凹凸屋根材１１の軒先端部の凸部１２の上端縁からは、図６に示すように、屋外側に向けて折曲自在な折曲片１１ａが延設されている。折曲片１１ａの大きさは、凸部１２の軒側の端部の開口（すなわち通気空間１７の長手方向に垂直な断面）と略同形同大となっており、折曲片１１ａが面戸の化粧面として機能する。 On the other hand, from the upper end edge of the convex part 12 of the eaves tip part of the uneven roof material 11, the bending piece 11a which can be bent toward the outdoor side is extended, as shown in FIG. The size of the bent piece 11a is substantially the same shape and size as the opening at the end of the eaves side of the convex portion 12 (that is, the cross section perpendicular to the longitudinal direction of the ventilation space 17). Acts as a decorative face for the door.

凹凸屋根材１１を面戸取付部２８に固定するに際し、まず図６に示すように、固定部材６の基部６０が野地板４の軒側の端部上に（本実施形態では軒側後誘導板５を介して）載置されて固定される。基部６０には、釘等の固着具の挿通孔６１が形成されていて、この挿通孔６１を介して固着具（不図示）が野地板４に打ち込まれることで、固定部材６が野地板４に固定される。面戸取付部２８の屋内側（棟側）の面には、面戸部材６２が設けられる。 When the uneven roofing material 11 is fixed to the face door mounting portion 28, first, as shown in FIG. 6, the base 60 of the fixing member 6 is placed on the eaves side end of the field board 4 (in this embodiment, eaves side rear guidance). It is placed and fixed (via plate 5). An insertion hole 61 for a fixing tool such as a nail is formed in the base 60, and a fixing tool (not shown) is driven into the base plate 4 through the insertion hole 61, so that the fixing member 6 is fixed to the base plate 4. Fixed to. A face door member 62 is provided on the face of the face door mounting portion 28 on the indoor side (ridge side).

本実施形態における面戸部材６２は、所謂ケミカル面戸、ソフト面戸と称される、ポリスチレン発泡体、ポリウレタン発泡体、ポリエチレン発泡体、等の発泡樹脂で形成される。なお、面戸部材６２は、弾性を有する水密性に優れた他の材質であってもよい。面戸部材６２は、図６に示すように、正面視形状が面戸取付部２８と通気空間１７の断面形状よりも大きく形成される。面戸部材６２が面戸取付部２８の屋内側の面に設けられるにあたっては、両面テープや接着剤による貼着が好ましいが、係合等による保持でもよく、特に限定されない。 The face door member 62 in the present embodiment is formed of a foamed resin such as a polystyrene foam, a polyurethane foam, a polyethylene foam, or the like called a so-called chemical face door or soft face door. The face door member 62 may be made of another material having elasticity and excellent water tightness. As shown in FIG. 6, the face door member 62 is formed so that the front view shape is larger than the cross-sectional shapes of the face door mounting portion 28 and the ventilation space 17. When the face door member 62 is provided on the indoor side surface of the face door mounting portion 28, sticking with a double-sided tape or an adhesive is preferable, but it may be held by engagement or the like, and is not particularly limited.

そして面戸取付部２８は、図７に示すように、各凸部１２の軒側端部（つまり通気空間１７の軒側端部）に一対一で突き合わされて嵌入され、嵌入された面戸取付部２８が通気空間１７の軒側開口を閉塞するように、凹凸屋根材１１が固定部材６上に配置される。このとき、面戸取付部２８と凹凸屋根材１１の凸部１２の軒側端部との間に、面戸部材６２が介在される。 Then, as shown in FIG. 7, the face door attaching portion 28 is fitted into the eaves side end portions of the convex portions 12 (that is, the eave side end portions of the ventilation space 17) in a one-to-one relationship, and is fitted. The uneven roof material 11 is arranged on the fixing member 6 so that the attachment portion 28 closes the eaves side opening of the ventilation space 17. At this time, the face door member 62 is interposed between the face door attaching portion 28 and the eaves side end portion of the convex portion 12 of the uneven roof material 11.

面戸取付部２８は、凹凸屋根材１１の凸部１２内の通気空間１７の断面形状と略同じ形状で若干小さく形成され、通気空間１７の軒側端部の開口内に挿入される。この時、面戸部材６２がない場合には、凹凸屋根材１１の凸部１２の内面と面戸取付部２８との間に、水が浸入可能な隙間が形成される惧れがある。本発明においては、面戸取付部２８と凹凸屋根材１１の軒側端部との間に面戸部材６２が介在するため、横方向の端部において面戸取付部２８と凹凸屋根材１１の軒側端部との間に水が浸入可能な隙間が殆ど形成されない。 The face door mounting portion 28 is formed to be slightly smaller in shape and substantially the same as the cross-sectional shape of the ventilation space 17 in the convex portion 12 of the uneven roof material 11, and is inserted into the opening at the eave side end portion of the ventilation space 17. At this time, when the face door member 62 is not present, there is a possibility that a gap into which water can enter is formed between the inner surface of the convex portion 12 of the uneven roof material 11 and the face door mounting portion 28. In the present invention, since the face door member 62 is interposed between the face door attaching portion 28 and the eaves side end portion of the uneven roof material 11, the face door attaching portion 28 and the uneven roof material 11 are arranged at the lateral ends. There is almost no gap into which water can enter between the eaves side end.

そして、面戸部材６２は、図７に示すように、面戸取付部２８とともに凹凸屋根材１１の凸部１２内の通気空間１７内に挿入されるが、面戸部材６２は通気空間１７の断面よりも大きいため、凸部１２内で圧縮され、凸部１２の内面に隙間無く当接する。そして、図８に示すように、凹凸屋根材１１の折曲片１１ａが下方に折曲され、面戸取付部２８の外面（軒側の面）に重ね合わせられる。折曲片１１ａには、固着具挿通孔１１ｂが形成されていて、この固着具挿通孔１１ｂを介して釘等の固着具（不図示）が面戸取付部２８に打ち込まれることで、凹凸屋根材１１が固定部材６に固定される。 As shown in FIG. 7, the face door member 62 is inserted into the ventilation space 17 in the convex portion 12 of the uneven roof material 11 together with the face door mounting portion 28. Since it is larger than the cross section, it is compressed in the convex part 12 and abuts against the inner surface of the convex part 12 without a gap. And as shown in FIG. 8, the bending piece 11a of the uneven | corrugated roof material 11 is bend | folded below, and is piled up on the outer surface (surface of eaves side) of the face door attaching part 28. FIG. The bent piece 11a is formed with a fixing tool insertion hole 11b, and a fixing tool (not shown) such as a nail is driven into the face door mounting portion 28 via the fixing tool insertion hole 11b. The material 11 is fixed to the fixing member 6.

この構造によれば、軒先に強風等の負荷が加えられても、その負荷によって凹凸屋根材１１の軒先部分がめくれ上がって外れることや、バタバタと異音を生じさせることが抑えられる。また、凹凸屋根材１１を野地板４に固定するに際して、凹凸屋根材１１の凹部１３をネジ、釘等で野地板４に固定する必要がなく、水仕舞いが良好となる。加えて、この構造によれば、軒方向Ｄ２に沿って凸部１２と凹部１３を交互に有する凹凸屋根材１１が、固定後に撓みを生じることも抑えられる。さらに、凹凸屋根材１１の軒先端縁の構造が、折曲片１１ａを折り曲げた構造となるので、凹凸屋根材１１の小口部分が軒先に露出することも抑えられる。 According to this structure, even when a load such as a strong wind is applied to the eaves, it is possible to prevent the eaves portion of the uneven roof material 11 from turning up and coming off due to the load, and to generate an abnormal noise with the flap. Further, when the uneven roof material 11 is fixed to the base plate 4, there is no need to fix the concave portion 13 of the uneven roof material 11 to the base plate 4 with screws, nails or the like, and the water finish is improved. In addition, according to this structure, the uneven roofing material 11 having the convex portions 12 and the concave portions 13 alternately along the eave direction D2 can be prevented from being bent after being fixed. Furthermore, since the structure of the eaves tip edge of the uneven roof material 11 is a structure in which the bent piece 11a is bent, the small edge portion of the uneven roof material 11 is also prevented from being exposed to the eaves edge.

さらに、面戸取付部２８と凹凸屋根材１１の凸部１２の軒側端部との間に、面戸部材６２が介在されるため、この間に水が浸入可能な隙間が形成されず、雨水が浸入するのが抑制されるものである。 Furthermore, since the face door member 62 is interposed between the face door attaching portion 28 and the eaves side end portion of the convex portion 12 of the uneven roof material 11, a gap into which water can enter is not formed, and rainwater Is prevented from entering.

さらに本実施形態では、隣接する凹凸屋根材１１間の部分を上側から覆うカバー部材１５にも、同様の固定構造を設けている。つまり、カバー部材１５が有する上壁部の軒側先端部から、前述の折曲片１１ａと同様の折曲片１５ａを軒棟方向Ｄ１の屋外側にむけて延設している。 Furthermore, in this embodiment, the same fixing structure is provided also in the cover member 15 which covers the part between the uneven | corrugated roof materials 11 adjacent from the upper side. That is, the bending piece 15a similar to the above-mentioned bending piece 11a is extended from the eaves side front-end | tip part of the upper wall part which the cover member 15 has toward the outdoor side of the eaves building direction D1.

このカバー部材１５も、対応する面戸取付部２８に対して上方から被せられる。このとき、カバー部材１５が有する１１ａが、面戸取付部２８と重なり合い、固着具によりカバー部材１５はこれに対応する面戸取付部２８に固定され、上述したのと同様の効果が得られる。 This cover member 15 is also covered from the upper side with respect to the corresponding face door attaching part 28. At this time, 11a which the cover member 15 has overlaps with the face door attaching part 28, and the cover member 15 is fixed to the corresponding face door attaching part 28 by a fixing tool, and the same effect as described above is obtained.

以上、本発明を添付図面に示す実施形態に基づいて説明したが、本発明は前記実施形態に限定されるものではない。例えば、本実施形態では、機能パネルを太陽光発電パネル４８で構成したが、その他の機能を有するパネルで構成しても構わないし、機能パネルを省略することも可能である。また、本発明は片流れ屋根だけではなく切妻屋根等のその他の形状の屋根にも適用可能である。その他の構成についても、本発明の意図する範囲内であれば、適宜の設計変更を行うことが可能である。 As mentioned above, although this invention was demonstrated based on embodiment shown to an accompanying drawing, this invention is not limited to the said embodiment. For example, in the present embodiment, the functional panel is configured by the solar power generation panel 48, but may be configured by a panel having other functions, or the functional panel may be omitted. Further, the present invention is applicable not only to a single-flow roof but also to roofs of other shapes such as a gable roof. For other configurations, appropriate design changes can be made within the range intended by the present invention.
