FIG. 1 is a perspective view showing part of a house 5 as an example of a building, and is a partial schematic perspective view of part of a roof structure 1 according to a first embodiment of the present disclosure. 2 is an enlarged perspective view of a part of the eaves side of the roof structure 1. FIG. As shown in FIG. 1 , the roof structure 1 includes a roof base material, a plurality of roof materials 10 and a plurality of water guide plates 20 . A plurality of roof materials 10 and water guide plates 20 are arranged, for example, adjacent to each other in the orthogonal direction. Moreover, as shown in FIG. 2 , each water guide plate 20 includes a plurality of ridges 21 . The plurality of ridges 21 are arranged at intervals in the eaves ridge direction, and each ridge 21 extends in the orthogonal direction.

図2に示すように、屋根構造1は、けらば水切り50を更に備える。けらば水切り50は、屋根構造1の直交方向の端部に配置される。けらば水切り50は、側面視が矩形状の板状部51を含み、板状部51は、鉛直方向に突出すると共に軒棟方向に延在する。各導水板20は、板状部51に対して直交方向に間隔をおいて配置される。導水板20と板状部51の間には、雨水を下方に流すための通路3が設けられる。通路3は、屋根材10の上面等で構成されて棟から軒先まで軒棟方向に延在する。 As shown in FIG. 2, the roof structure 1 further comprises a verge flasher 50 . A verge flasher 50 is arranged at the orthogonal end of the roof structure 1 . The bristle drainer 50 includes a plate-like portion 51 having a rectangular shape when viewed from the side, and the plate-like portion 51 protrudes in the vertical direction and extends in the eaves ridge direction. Each water guide plate 20 is arranged at intervals in the orthogonal direction with respect to the plate-like portion 51 . A passage 3 is provided between the water guide plate 20 and the plate-like portion 51 to allow rainwater to flow downward. The passage 3 is composed of the upper surface of the roof material 10 and the like, and extends from the ridge to the edge of the eaves in the eaves ridge direction.

図3は、図2のA-A線模式断面図であり、図4は、図3の一部を詳細に示す拡大断面図である。図3に示すように、屋根材10及び導水板20の夫々は、屋根下地材15上に配置され、屋根下地材15に固定される。屋根下地材15は、例えば、野地板で構成される。また、屋根材10は、如何なる屋根材でもよいが、例えば、セメントで構成される平板状のスレート、陶器で構成される平板状の瓦、又は金属製の瓦等で好適に構成される。また、導水板20は、如何なる材料で構成されてもよいが、好ましくは金属材料で構成される。 3 is a schematic cross-sectional view taken along line AA of FIG. 2, and FIG. 4 is an enlarged cross-sectional view showing a part of FIG. 3 in detail. As shown in FIG. 3 , the roof material 10 and the water guide plate 20 are placed on the roof substrate material 15 and fixed to the roof substrate material 15 . The roof base material 15 is composed of, for example, a sheathing board. Moreover, the roofing material 10 may be any roofing material, but is preferably composed of, for example, a flat slate made of cement, a flat tile made of ceramic, or a metal tile. Also, the water guide plate 20 may be made of any material, but is preferably made of a metal material.

鉛直方向上側から屋根構造1を見下ろしたとき、各導水板20は、外部に露出する外部露出部22を有し、外部露出部22は、複数の突条部(全ての突条部)21を含む。また、そのように屋根構造1を見たとき、各屋根材10も、外部に露出する外部露出部11を含む。鉛直方向上側から屋根構造1を見下ろしたとき、導水板20の外部露出部22と、屋根材10の外部露出部11とは、軒棟方向に交互に配置されている。換言すると、鉛直方向上側から屋根構造1を見下ろしたとき、直交方向の各位置において軒棟方向に隣り合う導水板20の外部露出部22の間の部分は、1つの屋根材10の外部露出部11で覆われている。 When looking down on the roof structure 1 from the upper side in the vertical direction, each water guide plate 20 has an externally exposed portion 22 that is exposed to the outside, and the externally exposed portion 22 includes a plurality of ridges (all ridges) 21. include. Moreover, when the roof structure 1 is viewed as such, each roofing material 10 also includes an externally exposed portion 11 that is exposed to the outside. When looking down on the roof structure 1 from the upper side in the vertical direction, the externally exposed portions 22 of the water guide plate 20 and the externally exposed portions 11 of the roof material 10 are alternately arranged in the eaves ridge direction. In other words, when looking down on the roof structure 1 from the upper side in the vertical direction, the portion between the externally exposed portions 22 of the water conducting plates 20 adjacent in the eaves ridge direction at each position in the orthogonal direction is the externally exposed portion of one roof material 10 11 covered.

次に、屋根下地材15に対する屋根材10と導水板20の固定構造について説明する。図4に示すように、各導水板20は、下側屋根材10aを覆うように配置される。詳しくは、導水板20は、軒棟方向の棟側に開口する凹部23を軒棟方向の軒側端部に有する。導水板20には直交方向に細長い矩形板状のベース20aがあり、このベース20aの軒側端が下方に一旦折り曲げられてさらに棟側に折り曲げられて断面コ字状をなし、棟側に開口する凹部23が形成されている。下側屋根材10aの軒棟方向の軒側端部12が凹部23に収容される。換言すれば、屋根構造1は、軒棟方向の軒側端部12が凹部23に収容される下側屋根材10aを備える。下側屋根材10aにおいてそれに隣り合う軒側の屋根材10bの棟側端部よりも棟側に位置する棟側箇所17は、下側屋根材10aに隣り合う棟側の屋根材10cに覆われる。棟側箇所17が釘7で屋根下地材15に固定されることで、下側屋根材10aが屋根下地材15に取り付けられる。 Next, the fixing structure of the roof material 10 and the water guide plate 20 to the roof base material 15 will be described. As shown in FIG. 4, each water guide plate 20 is arranged to cover the lower roof material 10a. More specifically, the water guide plate 20 has a concave portion 23 opening on the ridge side in the eaves ridge direction at the eaves side end portion in the eaves ridge direction. The water guide plate 20 has a rectangular plate-like base 20a elongated in the orthogonal direction, and the eaves side end of the base 20a is once bent downward and further bent to the ridge side to form a U-shaped cross section and open to the ridge side. A concave portion 23 is formed. The eaves-side end 12 of the lower roof material 10 a in the eaves ridge direction is accommodated in the recess 23 . In other words, the roof structure 1 includes the lower roof material 10 a having the eaves-side end 12 in the eaves ridge direction housed in the recess 23 . In the lower roof material 10a, a ridge-side portion 17 positioned closer to the ridge than the ridge-side end of the adjacent eaves-side roof material 10b is covered with the ridge-side roof material 10c adjacent to the lower roof material 10a. . The lower roof material 10a is attached to the roof base material 15 by fixing the ridge side portion 17 to the roof base material 15 with the nail 7. - 特許庁

また、各導水板20は、それが覆う下側屋根材10aよりも長い軒棟方向寸法を有し、軒棟方向に関して、下側屋根材10aの全ての領域を覆っている。このことから、各導水板20の上側に配置された屋根材同士の取付箇所から雨水が入っても各導水板20の表面を伝って軒側に排水可能である。各導水板20の軒棟方向の棟側端部25は、下側屋根材10aよりも棟側に位置する。棟側端部25は、屈曲して屋根下地材15に接している。棟側端部25を、釘8で屋根下地材15に固定することで、導水板20が屋根下地材15に取り付けられる。 In addition, each water guide plate 20 has a dimension in the eaves ridge direction that is longer than the lower roof material 10a it covers, and covers the entire area of the lower roof material 10a in the eaves ridge direction. Therefore, even if rainwater enters from the attachment points of the roof materials arranged above each water guide plate 20, it can be drained to the eaves side along the surface of each water guide plate 20. - 特許庁A ridge-side end portion 25 of each water guide plate 20 in the eaves-ridge direction is located closer to the ridge than the lower roof material 10a. The ridge-side end portion 25 is bent and contacts the roof base material 15 . By fixing the ridge-side end portion 25 to the roof base material 15 with a nail 8, the water guide plate 20 is attached to the roof base material 15.例文帳に追加

再度、図3を参照して、屋根構造1が含む複数の導水板20は、棟側導水板30と、軒側導水板35とを含み、棟側導水板30と、軒側導水板35は、複数の突条部21の構造が互いに異なる。次に、それらの突条部21の構造について説明する。なお、軒側導水板35は、全ての導水板20のうちで最も軒側に配置される。また、棟側導水板30は、軒側導水板35よりも軒棟方向の棟側に配置される。より正確には、棟側導水板30の軒側端30aは、軒側導水板35の軒側端35aよりも軒棟方向の棟側に位置する。 Again referring to FIG. 3 , the plurality of water conducting plates 20 included in the roof structure 1 include a ridge-side water conducting plate 30 and an eaves-side water conducting plate 35 , and the ridge-side water conducting plate 30 and the eaves-side water conducting plate 35 are , the structures of the plurality of ridges 21 are different from each other. Next, the structure of those protrusions 21 will be described. The eaves-side water guide plate 35 is arranged closest to the eaves of all the water guide plates 20 . Also, the ridge-side water conducting plate 30 is arranged closer to the ridge side in the eaves-ridge direction than the eaves-side water conducting plate 35 . More precisely, the eaves-side end 30 a of the ridge-side water conducting plate 30 is positioned closer to the ridge in the eaves-ridge direction than the eaves-side end 35 a of the eaves-side water conducting plate 35 .

図5は、屋根構造1に適切に設置されている状態の棟側導水板30における軒棟方向と鉛直方向とを含む切断面における模式断面図である。また、図6は、屋根構造1に適切に設置されている状態の軒側導水板35における軒棟方向と軒棟方向とを含む切断面における模式断面図である。 FIG. 5 is a schematic cross-sectional view of the ridge-side water conducting plate 30 properly installed on the roof structure 1 along a cross section including the eaves ridge direction and the vertical direction. FIG. 6 is a schematic cross-sectional view of the eaves-side water conducting plate 35 properly installed on the roof structure 1 along a cut plane including the eaves ridge direction and the eaves ridge direction.

図5に示すように、棟側導水板30は、軒棟方向に間隔をおいて位置する複数の突条部21を含み、各突条部21は、直交方向に延在する。突条部21は、ベース33から垂直に上方に延び且つ直交方向に細長い矩形板状をなす。また、棟側導水板30は、複数の突条部21よりも軒棟方向の棟側に位置する平坦部31を有する。図3に示すように、一つの屋根材10の軒棟方向の軒側端部14は、平坦部31の上側に配置される。図5に示すように、棟側導水板30の外部露出部22(図3も参照)は、略平面で構成される上面32を有するベース33を含み、各突条部21は、ベース33から矢印R1で示す平坦部31の上面34の法線方向(以下、R1方向という)に突出する。 As shown in FIG. 5, the ridge-side water conducting plate 30 includes a plurality of ridges 21 positioned at intervals in the eaves ridge direction, and each ridge 21 extends in the orthogonal direction. The ridge portion 21 extends vertically upward from the base 33 and has a rectangular plate shape elongated in the orthogonal direction. Further, the ridge-side water conducting plate 30 has a flat portion 31 positioned closer to the ridge in the eaves ridge direction than the plurality of ridges 21 . As shown in FIG. 3 , the eaves-side end 14 of one roof material 10 in the eaves ridge direction is arranged above the flat portion 31 . As shown in FIG. 5, the externally exposed portion 22 (see also FIG. 3) of the ridge-side water conducting plate 30 includes a base 33 having an upper surface 32 that is substantially planar, and each ridge portion 21 extends from the base 33. It protrudes in the direction normal to the upper surface 34 of the flat portion 31 indicated by the arrow R1 (hereinafter referred to as the R1 direction).

棟側導水板30の複数の突条部21に関して、突条部21のR1方向の高さは、突条部21が軒棟方向の軒側に配置されるにしたがって高くなっている。このことから、ベース20aと軒棟方向に隣り合う突条部21とで囲まれるスペースで雨水が一時的に貯水され、このように軒側ほど突条部21が高くなることで軒側ほど貯水容量が大きくなり、より多くの雨水を一時貯水して直交方向外側に流すことが可能になる。また、棟側導水板30の複数の突条部21に関して、突条部21の上端の鉛直方向の高さは、突条部21が軒棟方向の軒側に配置されるにしたがって低くなっている。 Regarding the plurality of ridge portions 21 of the ridge-side water conducting plate 30, the height of the ridge portions 21 in the R1 direction increases as the ridge portions 21 are arranged closer to the eaves side in the eaves ridge direction. Therefore, rainwater is temporarily stored in the space surrounded by the base 20a and the ridges 21 adjacent to each other in the direction of the eaves. The increased capacity allows more rainwater to be temporarily stored and channeled orthogonally outward. Further, regarding the plurality of ridge portions 21 of the ridge-side water conducting plate 30, the vertical height of the upper ends of the ridge portions 21 becomes lower as the ridge portions 21 are arranged closer to the eaves side in the eaves ridge direction. there is

一方、図6に示すように、軒側導水板35も、軒棟方向に間隔をおいて位置する複数の突条部21を含み、各突条部21は、直交方向に延在する。また、軒側導水板35も、複数の突条部21よりも軒棟方向の棟側に位置する平坦部36を有する。また、図3に示すように、一つの屋根材10の軒棟方向の軒側端部14は、平坦部36の上側に配置される。また、図6に示すように、軒側導水板35の外部露出部22(図3参照)も、略平面で構成される上面37を有するベース38を含み、各突条部21は、ベース38から矢印R2で示す平坦部36の上面39の法線方向(以下、R2方向という)に突出する。軒側導水板35の複数の突条部21に関して、突条部21のR2方向の高さは、略一定になっている。軒側導水板35の突条部21のR2方向の高さは、如何なる高さでもよいが、棟側導水板30の複数の突条部21のうちでR1方向の高さが最も高い最も軒側に位置する突条部21a(図5参照)におけるR1方向の高さ以上の高さを有すると好ましい。 On the other hand, as shown in FIG. 6, the eaves-side water conducting plate 35 also includes a plurality of ridges 21 positioned at intervals in the eaves ridge direction, and each ridge 21 extends in the orthogonal direction. The eaves-side water conducting plate 35 also has a flat portion 36 positioned closer to the ridge in the eaves ridge direction than the plurality of ridges 21 . In addition, as shown in FIG. 3 , the eaves-side end portion 14 of one roof material 10 in the eaves ridge direction is arranged above the flat portion 36 . In addition, as shown in FIG. 6, the externally exposed portion 22 (see FIG. 3) of the eaves-side water conducting plate 35 also includes a base 38 having a substantially planar upper surface 37. , in the normal direction of the upper surface 39 of the flat portion 36 indicated by the arrow R2 (hereinafter referred to as the R2 direction). Regarding the plurality of ridges 21 of the eaves-side water conducting plate 35, the height of the ridges 21 in the R2 direction is substantially constant. The height of the ridges 21 of the eaves-side water conducting plate 35 in the R2 direction may be any height, but among the plurality of ridges 21 of the ridge-side water conducting plate 30, the height in the R1 direction is the highest. It is preferable to have a height equal to or greater than the height in the R1 direction of the protrusion 21a (see FIG. 5) located on the side.

次に屋根構造1における雨水の流れについて説明する。再度、図2を参照して、屋根構造1は、上述のように、けらば水切り50を備える。図7は、けらば水切り50の斜視図である。けらば水切り50は、例えば、一体の金属板を折り曲げ加工して形成される。詳述しないが、けらば水切り50は、鉛直方向に延在する上述の板状部51の他に、第1カバー部52と、第2カバー部53を有する。上述のように、けらば水切り50は板状部51が鉛直方向に突出すると共に軒棟方向に延在するように屋根下地材15の直交方向の端部に取り付けられる。 Next, rainwater flow in the roof structure 1 will be described. Again referring to FIG. 2, the roof structure 1 is provided with a verge flasher 50 as described above. FIG. 7 is a perspective view of the colander drainer 50. As shown in FIG. The colander drainer 50 is formed, for example, by bending an integral metal plate. Although not described in detail, the colander drainer 50 has a first cover portion 52 and a second cover portion 53 in addition to the plate-like portion 51 extending in the vertical direction. As described above, the flake drainer 50 is attached to the end of the roof base material 15 in the orthogonal direction so that the plate-like portion 51 protrudes vertically and extends in the eaves ridge direction.

けらば水切り50が、屋根下地材15に取り付けられた状態で、第1カバー部52は、屋根下地材15の直交方向の一端部を覆うようになっている。第1カバー部52は、屋根構造1の美観を優れたものする役割等を担う。また、第2カバー部53は、板状部51の下端部に接続され、直交方向の他方側に開口する凹部54を有する。この凹部54には、屋根材10の直交方向の一端部が差し込まれる。第2カバー部53は、その下側端部に直交方向の中央側に延在して屋根下地材15上に載置される下側板部55を有する。下側板部55には、軒棟方向に延在する複数の突条部56が設けられ、複数の突条部56は、直交方向に互いに間隔をおいて配置される。凹部54の内面と屋根材10との間に浸入した雨水が、直交方向の中央側に移動すると、雨漏りの原因になる虞がある。突条部56は、凹部54の内面と屋根材10との間に浸入した雨水が直交方向の中央側に移動することを抑制するために設けられる。 The first cover part 52 covers one end of the roof base material 15 in the orthogonal direction in a state where the hooked drainer 50 is attached to the roof base material 15 . The first cover portion 52 plays a role of improving the appearance of the roof structure 1, and the like. The second cover portion 53 also has a recess 54 that is connected to the lower end portion of the plate-like portion 51 and opens on the other side in the orthogonal direction. One end of the roofing material 10 in the orthogonal direction is inserted into the concave portion 54 . The second cover portion 53 has a lower plate portion 55 that extends toward the center in the orthogonal direction and is placed on the roof base material 15 at its lower end portion. The lower plate portion 55 is provided with a plurality of protrusions 56 extending in the eaves ridge direction, and the plurality of protrusions 56 are arranged at intervals in the orthogonal direction. If the rainwater that has entered between the inner surface of the recess 54 and the roofing material 10 moves toward the center in the orthogonal direction, it may cause rain leakage. The ridges 56 are provided to prevent rainwater that has entered between the inner surface of the recess 54 and the roofing material 10 from moving toward the center in the orthogonal direction.

雨水は、例えば、図8に矢印βに示す経路で屋根構造1の上面上を流下する。詳しくは、降雨によって棟側から軒側に軒棟方向に流下して棟側導水板30に到達した雨水は、雨量に基づいて棟側導水板30の突条部21を1つも乗り越えないか、又はR1方向高さ(図5参照)が低い順に1以上の突条部21を乗り越える。例えば、図8には、雨水の一部が上側から2つの突条部21を乗り越える場合が図示されている。この場合、雨水の一部は、最も棟側の突条部21における棟側の側面で内外方向の端側に案内されて、上述の通路3に到達する。また、他の雨水の一部は、最も棟側の突条部21を乗り超え、棟側から数えて2番目の突条部21における棟側の側面で内外方向の端側に案内されて、上述の通路3に到達する。また、更なる他の雨水の一部は、棟側から数えて2つの突条部21を乗り越え、棟側から数えて3番目の突条部21における棟側の側面で内外方向の端側に案内されて、上述の通路3に到達する。そして、異なる3つのルートを通って通路3に到達した雨水は、軒棟方向に延在する通路3を軒側に流下する。 Rainwater flows down on the upper surface of the roof structure 1, for example, along the route indicated by the arrow β in FIG. Specifically, rainwater that flows down from the ridge side to the eaves side in the direction of the eaves due to rainfall and reaches the ridge-side water guide plate 30 does not get over even one of the ridges 21 of the ridge-side water guide plate 30 based on the amount of rainfall. Alternatively, it climbs over one or more ridges 21 in ascending order of height in the R1 direction (see FIG. 5). For example, FIG. 8 shows a case where part of the rainwater runs over the two ridges 21 from above. In this case, part of the rainwater is guided to the inner and outer ends by the ridge-side side surface of the protrusion 21 closest to the ridge, and reaches the passage 3 . In addition, part of the other rainwater passes over the ridge portion 21 closest to the ridge and is guided to the inner and outer ends on the ridge side surface of the second ridge portion 21 counted from the ridge side, Passage 3 mentioned above is reached. Further, a part of the other rainwater climbs over the two ridges 21 counted from the ridge side, and flows to the inner and outer ends on the ridge side surface of the third ridged ridge 21 counted from the ridge side. It is guided to reach passage 3 mentioned above. Rainwater reaching the passage 3 through three different routes flows down the passage 3 extending in the direction of the eaves.

図8に示すように、家屋は、例えば、建物の軒先側の壁部60に取り付けられた集水桝61と、集水桝61の下側端部に接続された竪樋62を備える。集水桝61は、その集水口64の直交方向の存在範囲が通路3の直交方向の存在範囲を含むように壁部60に取り付けられる。このため、雨水は、通路3に沿って流下して通路3の軒側の端に到達した後に集水口64に効率良く流入する。集水口64から集水桝61内に流入した雨水は、竪樋62を通過した後、地上又は下水の方に流れるようになっている。また、板状部51が、通路3の直交方向の端側の側面を画定し、鉛直方向に突出すると共に軒棟方向に延在している。したがって、雨水が豪雨時等に突条部21の側面を高速で伝って通路3側に勢い良く飛び出したとしても、板状部51に衝突して通路3側にはね返される。よって、通路3側に勢い良く飛び出した雨水が、家屋の外部にそのまま飛散することを効果的に抑制できる。 As shown in FIG. 8, the house includes, for example, a water collection pit 61 attached to a wall 60 on the eaves side of the building, and a downspout 62 connected to the lower end of the water collection pit 61 . The water collecting basin 61 is attached to the wall portion 60 so that the existence range of the water collection port 64 in the orthogonal direction includes the existence range of the passage 3 in the orthogonal direction. Therefore, the rainwater flows down along the passage 3 and efficiently flows into the water collecting port 64 after reaching the end of the passage 3 on the eaves side. The rainwater that has flowed into the water collection basin 61 from the water collection port 64 passes through the downpipe 62, and then flows to the ground or sewage. A plate-like portion 51 defines the side surface of the passage 3 on the end side in the orthogonal direction, protrudes in the vertical direction, and extends in the eaves ridge direction. Therefore, even if rainwater runs along the side surface of the ridge portion 21 at high speed and rushes toward the passage 3 during a heavy rain or the like, it collides with the plate-like portion 51 and is repelled toward the passage 3.例文帳に追加Therefore, it is possible to effectively prevent the rainwater rushing out toward the passage 3 from splashing outside the house.

以上、屋根構造1は、家屋(建築物)5の上側に配置される。また、屋根構造1は、軒棟方向に直交する直交方向に略延在する1以上の突条部21、及び突条部21よりも軒棟方向の棟側に位置する平坦部31,36を有する1以上の導水板20,30,35と、軒棟方向の軒側の軒側端部14が平坦部31,36の上側に配置される1以上の屋根材10,10b,10cと、を備える。 As described above, the roof structure 1 is arranged above the house (building) 5 . In addition, the roof structure 1 includes one or more ridges 21 substantially extending in an orthogonal direction orthogonal to the eaves ridge direction, and flat portions 31 and 36 positioned closer to the ridge than the ridges 21 in the eaves ridge direction. one or more water guide plates 20, 30, 35, and one or more roofing materials 10, 10b, 10c having the eaves side edge 14 on the eaves side in the eaves ridge direction disposed above the flat parts 31, 36 Prepare.

したがって、導水板20が、直交方向に延在する突条部21を備えるので、軒棟方向に下側に流れる雨水を突条部21で堰き止めることができ、堰き止めた雨水を、突条部21を伝わせるように直交方向に流すことができ、雨水を屋根構造1の一方側の側方端部に集めることができる。そして、一方側の側方端部に集めた雨水を、一方側の側方端部に設けた通路3、集水桝61、及び竪樋62を介して下側に導くことができる。よって、突条部21に軒樋の役割を担わせることができるので、軒樋を省略することができ、家屋5を、スタイリッシュで美観に優れるものにでき、コンパクトに構成できる。 Therefore, since the water guide plate 20 is provided with the ridges 21 extending in the orthogonal direction, the ridges 21 can dam the rainwater flowing downward in the direction of the eaves ridges. It is possible to run orthogonally along the section 21 and to collect rainwater at one lateral edge of the roof structure 1 . Then, the rainwater collected at one side end can be guided downward through the passage 3, the water collection pit 61, and the downspout 62 provided at the one side end. Therefore, since the projecting ridge part 21 can play the role of an eaves gutter, the eaves gutter can be omitted, and the house 5 can be made stylish and beautiful, and compact.

また、導水板20が、軒棟方向の棟側に開口する凹部23を軒棟方向の軒側端部に有してもよい。また、屋根構造1が、軒棟方向の軒側端部12が凹部23に収容される1以上の下側屋根材10aを更に備えてもよい。そして、導水板20が、下側屋根材10aを覆うように配置されてもよい。 Further, the water guide plate 20 may have a concave portion 23 opening on the ridge side in the eaves ridge direction at the eaves side end portion in the eaves ridge direction. In addition, the roof structure 1 may further include one or more lower roof members 10 a whose eaves-side ends 12 in the eaves ridge direction are accommodated in the recesses 23 . Then, the water guide plate 20 may be arranged so as to cover the lower roof material 10a.

本構成によれば、導水板20が、雨漏りを防止するために設けられる既存の屋根材10を覆うように配置され、既存の屋根材10を用いて設置される。よって、雨漏りを防止する屋根材10,10a,10b,10cの構造及び配置を殆ど変更しなくてもよいので、導水板20を設けることで雨漏りが生じる可能性を小さくできる。また、導水板20を既存の屋根材10aを用いて簡単安価に設置できる。 According to this configuration, the water guide plate 20 is arranged so as to cover the existing roofing material 10 provided to prevent rain leakage, and is installed using the existing roofing material 10 . Therefore, the structure and arrangement of the roof materials 10, 10a, 10b, and 10c that prevent rain leakage need not be changed, and the provision of the water guide plate 20 can reduce the possibility of rain leakage. Moreover, the water guide plate 20 can be installed simply and inexpensively using the existing roof material 10a.

また、屋根構造1は、複数の導水板20を備えてもよい。そして、複数の導水板20は、軒棟方向の軒側端が軒棟方向に互いに間隔をおいて位置するように配置されてもよい。 Also, the roof structure 1 may comprise a plurality of water guide plates 20 . The plurality of water guide plates 20 may be arranged such that the eaves side ends in the eaves ridge direction are spaced apart from each other in the eaves ridge direction.

本構成によれば、導水板20の1以上の突条部21を、軒棟方向に複数段に亘って設けることができる。よって、大雨が降った場合でも、雨水が軒棟方向に流下することを効果的に抑制でき、軒先から外部に飛散することを効果的に抑制できる。 According to this configuration, one or more protrusions 21 of the water guide plate 20 can be provided over a plurality of stages in the eaves ridge direction. Therefore, even when it rains heavily, it is possible to effectively prevent rainwater from flowing down in the direction of the eaves, and to effectively prevent rainwater from splashing outside from the edge of the eaves.

また、複数の導水板20が、軒棟方向に間隔をおいて位置する複数の突条部21を含む軒側導水板35と、軒側端が軒側導水板35の軒側端よりも軒棟方向の棟側に位置すると共に軒棟方向に間隔をおいて位置する複数の突条部21を含む棟側導水板30とを含んでもよい。また、棟側導水板30の平坦部31の上面34の法線方向をR1方向(第1法線方向)とするとき、棟側導水板30の複数の突条部21に関して、突条部21のR1方向の高さは、突条部21が軒棟方向の軒側に配置されるにしたがって高くなってもよい。また、軒側導水板35の平坦部36の上面39の法線方向を第2法線方向(R2方向)とするとき、軒側導水板35の複数の突条部21に関して、突条部21のR2方向の高さは、略一定になっていてもよい。 In addition, the plurality of water guide plates 20 includes an eaves-side water guide plate 35 including a plurality of ridges 21 positioned at intervals in the eaves-ridge direction, and the eaves-side end of the eaves-side water guide plate 35 is positioned further along the eaves than the eaves-side end of the eaves-side water guide plate 35 . A ridge-side water guide plate 30 including a plurality of protrusions 21 positioned on the ridge side in the ridge direction and positioned at intervals in the eaves ridge direction may also be included. Further, when the normal direction of the upper surface 34 of the flat portion 31 of the ridge-side water guide plate 30 is the R1 direction (first normal direction), the plurality of protrusions 21 of the ridge-side water guide plate 30 The height in the R1 direction of may increase as the protrusion 21 is arranged closer to the eaves side in the eaves ridge direction. Further, when the normal direction of the upper surface 39 of the flat portion 36 of the eaves-side water guide plate 35 is the second normal direction (R2 direction), the plurality of protrusions 21 of the eaves-side water guide plate 35 may be substantially constant in the R2 direction.

本構成によれば、棟側導水板30の複数の突条部21に関して、突条部21のR1方向の高さが、突条部21が軒棟方向の軒側に配置されるにしたがって高くなっている。したがって、隣り合う突条部21間のスペースで収容しきれなくなって、その突条部21を乗り越えて軒側にこぼれた雨水は、その突条部21よりも1つ軒側の突条部21を通過することがなく、その1つ軒側の突条部21で確実に堰き止められる。よって、棟側導水板30により多くの雨水を溜めることができるので、大量の雨水が一気に集水桝61に流れ込むことを抑制でき、雨水が集水桝61からこぼれることを抑制できる。 According to this configuration, with respect to the plurality of protrusions 21 of the ridge-side water conducting plate 30, the height of the protrusions 21 in the R1 direction increases as the protrusions 21 are arranged on the eaves side in the eaves ridge direction. It's becoming Therefore, the rainwater that cannot be accommodated in the space between the adjacent ridges 21 and spills over the ridges 21 to the eaves side is without passing through, and is reliably dammed by the projection 21 on the one eave side. Therefore, a large amount of rainwater can be stored in the ridge-side water guide plate 30, so that a large amount of rainwater can be suppressed from flowing into the water collection pit 61 at once, and rainwater can be suppressed from spilling out of the water collection pit 61. - 特許庁

また、軒側導水板35の複数の突条部21に関して、突条部21のR2方向の高さが略一定高さとなっているので、その複数の突条部21の棟側で溜めることが可能な雨水の容量を大きくできる。したがって、例えば、集中豪雨が発生して、大量の雨水が棟側導水板30の複数の突条部21を乗り越えて軒棟方向に流下して、軒側導水板35に到達したとしても、その大量の雨水が軒先から外部に飛散することを効果的に抑制できる。 In addition, regarding the plurality of ridges 21 of the eaves-side water conducting plate 35, since the height of the ridges 21 in the R2 direction is substantially constant, water can be collected on the ridge side of the plurality of ridges 21. It can increase the available rainwater capacity. Therefore, for example, even if a torrential rain occurs and a large amount of rainwater flows down in the eaves ridge direction over the plurality of ridges 21 of the ridge-side water guide plate 30 and reaches the eaves-side water guide plate 35, It is possible to effectively suppress splashing of a large amount of rainwater from the eaves to the outside.

更には、棟側導水板30の複数の突条部21に関して、突条部21の先端における鉛直方向の高さが、突条部21が軒側に配置されるにしたがって低くなっていてもよい。この場合、突条部21の鉛直方向高さが軒側に行くにしたがって高くなっていることを目立ちにくくできるので、棟側導水板30の美観を良好なものにできる。更には、軒先が、厚く見えず、スマートに見え、軒先の美観も良好なものにできる。 Furthermore, regarding the plurality of ridges 21 of the ridge-side water conducting plate 30, the vertical height at the tip of the ridges 21 may decrease as the ridges 21 are arranged closer to the eaves. . In this case, the increase in the vertical height of the ridges 21 toward the eaves can be made less conspicuous, so that the ridge-side water conducting plate 30 can be aesthetically pleasing. Furthermore, the edge of the eaves does not look thick, it looks smart, and the appearance of the edge of the eaves can be improved.

また、各導水板20が、鉛直方向の上側から見たときに外部に露出すると共に1以上の突条部21を含む外部露出部22を含んでもよい。また、鉛直方向上側から見たときに、直交方向の各位置において軒棟方向に隣り合う外部露出部22の間の部分が屋根材10の外部露出部22(1つの屋根材10の一部)で覆われてもよい。 Further, each water guide plate 20 may include an externally exposed portion 22 that is exposed to the outside when viewed from above in the vertical direction and that includes one or more ridges 21 . In addition, when viewed from the upper side in the vertical direction, the portion between the externally exposed portions 22 adjacent in the eaves ridge direction at each position in the orthogonal direction is the externally exposed portion 22 of the roofing material 10 (a part of one roofing material 10). may be covered with

導水板20は、例えば、押出加工で形成されるが、導水板20の平坦部31の厚さが薄いと金属加工が容易となって好ましい。 The water guide plate 20 is formed by, for example, extrusion processing, and it is preferable if the thickness of the flat portion 31 of the water guide plate 20 is thin because it facilitates metal processing.

このような背景において、軒棟方向に隣り合う外部露出部22の間の部分が屋根材10の外部露出部22で覆われる構成では、図4に示すように、導水板20の平坦部31を二つの屋根材10の間に配置できる。したがって、例えば、屋根材として、ある程度の厚さを有する屋根材、例えばセメント製で平板状のスレート等が採用されて、導水板20の平坦部31の厚さが屋根材10の厚さよりも薄い場合に、厚さが薄い平坦部31で二つの屋根材10の間を効果的に塞ぐことができ、二つの屋根材10の隙間を小さくできる。よって、雨水が二つの屋根材10の隙間を介して屋根材10の下側に回り込むのを抑制でき、雨漏りを効果的に抑制できる。 In such a background, in a configuration in which the portions between the externally exposed portions 22 adjacent in the eaves ridge direction are covered with the externally exposed portions 22 of the roofing material 10, as shown in FIG. It can be arranged between two roofing materials 10 . Therefore, for example, a roof material having a certain thickness, such as cement slate, is adopted as the roof material, and the thickness of the flat portion 31 of the water guide plate 20 is thinner than the thickness of the roof material 10. In this case, the thin flat portion 31 can effectively block the space between the two roofing materials 10, and the gap between the two roofing materials 10 can be reduced. Therefore, it is possible to prevent rainwater from flowing into the lower side of the roofing material 10 through the gap between the two roofing materials 10, thereby effectively suppressing rain leakage.

また、導水板20は、家屋5の上側に位置する屋根構造1に含まれる。また、屋根構造1に設置されている状態において、導水板20は、直交方向に略延在する1以上の突条部21と、突条部21よりも軒棟方向の棟側に位置する平坦部31,36と、を備える。また、屋根構造1に設置されている状態において、平坦部31,36の棟側の少なくとも一部が、屋根材10,10b,10cの下に配置される。 Also, the water guide plate 20 is included in the roof structure 1 positioned above the house 5 . In addition, in the state where it is installed on the roof structure 1, the water guide plate 20 includes one or more ridges 21 extending substantially in the orthogonal direction and a flat plate located closer to the ridge in the eaves ridge direction than the ridges 21. Sections 31 and 36 are provided. Moreover, in the state where it is installed on the roof structure 1, at least a part of the flat portions 31, 36 on the ridge side is arranged under the roof materials 10, 10b, 10c.

本開示の導水板20を用いれば、突条部21に軒樋の役割を担わせることができるので、軒樋を省略することができ、家屋5を、スタイリッシュで美観に優れるものにでき、コンパクトに構成できる。 If the water guide plate 20 of the present disclosure is used, the projecting portion 21 can play the role of the eaves gutter, so the eaves gutter can be omitted, and the house 5 can be made stylish, aesthetically pleasing, and compact. can be configured to

また、導水板20は、上面32を有するベース33、及びその上面32から平坦部31の上面34の法線方向(R1方向)に突出する複数の突条部21を有してもよい。また、屋根構造1に設置されている状態において、複数の突条部21に関して、突条部21が軒棟方向の軒側に位置するにしたがって突条部21におけるR1方向の高さが高くなってもよい。 Further, the water guide plate 20 may have a base 33 having an upper surface 32 and a plurality of ridges 21 projecting from the upper surface 32 in the normal direction (R1 direction) of the upper surface 34 of the flat portion 31 . Further, in the state of being installed on the roof structure 1, the height of the plurality of protrusions 21 in the R1 direction increases as the protrusions 21 are positioned closer to the eaves side in the eaves ridge direction. may

本構成によれば、導水板20により多くの雨水を通路3に流すことができるので、大量の雨水が一気に集水桝61に流れ込むことを抑制でき、雨水が集水桝61からこぼれることを抑制できる。また、導水板20の美観も優れたものにできる。 According to this configuration, a large amount of rainwater can be flowed to the passage 3 by the water guide plate 20, so that a large amount of rainwater can be suppressed from flowing into the water collection basin 61 at once, and rainwater can be suppressed from spilling out of the water collection basin 61. can. Also, the appearance of the water guide plate 20 can be improved.

It may be composed of an integral bending plate portion that has bending portions 230 a and 230 b and defines three directions of a substantially rectangular space 240 . Specifically, the ridge portion 221 may have an eaves side wall portion 241 , an upper side plate portion 242 and a ridge side wall portion 243 . The eaves side wall portion 241 may extend in the R4 direction from the ridge side end portion in the eaves ridge direction of the bottom side plate portion 251 including the upper surface 250 .

By configuring the ridge portion 221 with a bent plate portion having two bent portions 230a and 230b, the rigidity of the ridge portion 221 can be increased, and the ridge portion 221 is less likely to be damaged even when an external force acts. can be

また、念のため述べるが、導水板が備える突条部の数は、1以上の如何なる数でもよい。また、導水板が複数の突条部を有する場合、その各突条部の高さは、他の突条部の高さと無関係に独立に決定されることができ、各突条部の高さは、如何なる高さでもよい。また、鉛直方向上側から見たとき、導水板20と屋根材10が軒棟方向に関して交互に配置される場合について説明した。しかし、鉛直方向上側から見たとき、屋根構造が、2つの導水板が軒棟方向に関して隣り合うように配置される部分を有してもよい。また、屋根構造において、導水板が軒棟方向に関して1段にしか設けられない構成でもよく、この場合、導水板を最も軒側に設けるのが好ましい。 Also, just to make sure, the number of ridges included in the water guide plate may be any number of 1 or more. In addition, when the water guide plate has a plurality of ridges, the height of each ridge can be determined independently of the height of the other ridges, and the height of each ridge is can be of any height. Also, the case where the water guide plate 20 and the roof material 10 are alternately arranged in the eaves ridge direction when viewed from above in the vertical direction has been described. However, when viewed from above in the vertical direction, the roof structure may have a portion where two water conducting plates are arranged adjacent to each other in the eaves direction. Moreover, in the roof structure, the water conducting plate may be provided only in one stage in the direction of the eaves. In this case, it is preferable to provide the water conducting plate closest to the eaves.

(第2実施形態)
図11は、建築物の一例としての家屋305の一部を示す斜視図であり、第2実施形態に係る屋根構造301の一部の部分模式斜視図である。なお、第2実施形態では、第1実施形態と同一の構成には第1実施形態と同一の参照番号を付して説明を省略する。また、第2実施形態では、第1実施形態と同様の作用効果及び変形例についての説明を省略する。
(Second embodiment)
FIG. 11 is a perspective view showing part of a house 305 as an example of a building, and is a partial schematic perspective view of part of a roof structure 301 according to the second embodiment. In addition, in 2nd Embodiment, the reference number same as 1st Embodiment is attached|subjected to the same structure as 1st Embodiment, and description is abbreviate|omitted. In addition, in the second embodiment, the description of the effects and modifications similar to those of the first embodiment will be omitted.

第2実施形態では、導水板320が雨水を通過させるための通路303を有する点が、第1実施形態で説明した導水板20,30,35と異なる。詳しくは、屋根構造301は、直交方向の端部を含む部分に配置される導水板320を備える。また、導水板320は、1以上の突条部321と、装飾部370を有し、装飾部370は、1以上の突条部321よりも直交方向の端側に位置し、直交方向の端部に配置される。装飾部370は、1以上の突条部321に対して直交方向に間隔をおいて配置されている。 The second embodiment differs from the water guide plates 20, 30, and 35 described in the first embodiment in that a water guide plate 320 has passages 303 for passing rainwater. Specifically, the roof structure 301 comprises a water conducting plate 320 located in a portion including the orthogonal ends. Further, the water guide plate 320 has one or more ridges 321 and a decorative portion 370. The decoration 370 is positioned closer to the end in the orthogonal direction than the one or more ridges 321 and placed in the department. The decorative portion 370 is spaced apart in the orthogonal direction with respect to the one or more ridges 321 .

1以上の突条部321の直交方向における装飾部370側の端の直交方向位置は、全て略同じ位置となっている。装飾部370も、1以上の突条部321と同じ数の1以上の突条部325を有し、1以上の突条部321と1以上の突条部325は、直交方向から見たとき重なる位置に配置されている。各突条部321とそれに直交方向に重なる突条部325は、同じ方向に延在し、高さも同一となっている。また、装飾部370における突条部325側の端は、軒棟方向に延在している。このことから、1以上の突条部321と、装飾部370との直交方向の間には、軒棟方向に延在する通路303が設けられている。 The orthogonal positions of the ends of the one or more ridges 321 on the side of the decorative portion 370 in the orthogonal direction are all substantially the same. The decorative portion 370 also has the same number of the one or more ridges 325 as the one or more ridges 321, and the one or more ridges 321 and the one or more ridges 325 are, when viewed from the orthogonal direction, placed in overlapping positions. Each ridge portion 321 and the ridge portion 325 overlapping it in the orthogonal direction extend in the same direction and have the same height. In addition, the end of the decorative portion 370 on the protruding portion 325 side extends in the eaves ridge direction. Accordingly, a passage 303 extending in the eaves ridge direction is provided between the one or more ridges 321 and the decorative portion 370 in the orthogonal direction.

装飾部370の1以上の突条部325は、1以上の突条部321と次の点が異なっている。すなわち、1以上の突条部321が、直交方向の装飾部370側が開口されているのに対し、装飾部370の1以上の突条部325は、直交方向の突条部321側の端が、平板部327で塞がれている。このことから、突条部321の棟側の側面に沿って直交方向に案内された雨水が、通路303を介して軒棟方向下側に流下できるのに対し、突条部325の棟側の側面で堰き止められた雨水は、通路303側に流れることができず、家屋305の端から外部に飛散するようになっている。装飾部370は、屋根構造301の直交方向端部のみに配置されるので、装飾部370の突条部325を伝って外部に飛散する雨水の量は少量に留まり、人がその飛散で悪影響を受けることは殆どない。よって、装飾部370は、主に直交方向の外側から屋根構造301を見たときの美観を良好なものにするために設けられる。 The one or more ridges 325 of the decorative portion 370 differ from the one or more ridges 321 in the following points. That is, the one or more ridges 321 are open on the side of the decorative portion 370 in the orthogonal direction, whereas the one or more ridges 325 of the decoration 370 are opened on the side of the ridge 321 in the orthogonal direction. , is closed by a flat plate portion 327 . As a result, the rainwater guided in the orthogonal direction along the ridge-side side surface of the ridge portion 321 can flow downward in the eaves ridge direction through the passage 303, whereas the ridge-side surface of the ridge portion 325 can flow downward. The rainwater dammed up on the side cannot flow to the passage 303 side, and is splashed outside from the end of the house 305. - 特許庁Since the decorative portion 370 is arranged only at the end portion in the orthogonal direction of the roof structure 301, the amount of rainwater that scatters to the outside along the ridge portion 325 of the decorative portion 370 remains small, and people are not adversely affected by the splashing. I receive very little. Therefore, the decorative portion 370 is provided mainly to improve the appearance of the roof structure 301 when viewed from the outside in the orthogonal direction.

図11にγで示す経路は、屋根構造301上を流れる雨水の流下経路の一例である。この例に示すように、いずれかの突条部321の棟側の側面を伝って通路303に到達した雨水は、通路303上を流下し、その後、集水桝361、及び竪樋362を通過して、地上又は下水側に流れる。屋根構造301は、第1実施形態の屋根構造1と異なって、けらば水切り50を有さない。よって、施工が容易なものになって、製造コストも低減し易い。 A route indicated by γ in FIG. 11 is an example of a downflow route of rainwater flowing on the roof structure 301 . As shown in this example, rainwater that has reached the passage 303 along the ridge-side side surface of any of the ridges 321 flows down the passage 303, and then passes through the water collection pit 361 and the downspout 362. and flow to the ground or sewer side. Unlike the roof structure 1 of the first embodiment, the roof structure 301 does not have veneers 50 . Therefore, the construction becomes easy, and the manufacturing cost can be easily reduced.

図12は、第2実施形態の変形例の屋根構造401における図11に対応する斜視図である。図12に示すように、屋根構造401は、複数の導水板420,425を備え、複数の導水板420,425は、下側導水板425と、軒側端が下側導水板425の軒側端よりも軒棟方向の棟側に位置する上側導水板420とを含む。屋根構造401では、上側の上側導水板420における1以上の突条部421の直交方向長さが、下側の下側導水板425における1以上の突条部421の直交方向長さよりも短くなっている。換言すると、上側導水板420の1以上の突条部421における直交方向の一方側の端461が、下側導水板425の1以上の突条部421における直交方向の一方側の端462よりも直交方向の他方側に位置している。 FIG. 12 is a perspective view corresponding to FIG. 11 in the roof structure 401 of the modified example of the second embodiment. As shown in FIG. 12 , the roof structure 401 includes a plurality of water guide plates 420 , 425 , each of which has a lower water guide plate 425 and an eaves side edge of the lower water guide plate 425 . and an upper water guide plate 420 located on the ridge side in the eaves ridge direction than the edge. In the roof structure 401, the orthogonal length of the one or more ridges 421 in the upper water guide plate 420 on the upper side is shorter than the orthogonal length of the one or more ridges 421 in the lower water guide plate 425 on the lower side. ing. In other words, one end 461 of the one or more ridges 421 of the upper water guide plate 420 in the orthogonal direction is located closer to the one end 462 of the one or more ridges 421 of the lower water guide plate 425 in the orthogonal direction. It is located on the other side in the orthogonal direction.

屋根構造401によれば、上側導水板420の突条部421における直交方向の一方側の端461が、下側導水板425の突条部421における直交方向の一方側の端462よりも直交方向の他方側に位置している。したがって、図12にδで示す雨水の流下経路のように、雨水は、屋根構造401上の軒棟方向の棟側において、より直交方向の中央側を流れ易くなる。よって、雨水が、屋根構造401の直交方向の一方側の端から外部に飛散することを効果的に抑制できる。なお、図12に示すように、上側導水板420は、装飾部370を有している。しかし、上側導水板420との比較において装飾部370が存在しない点のみが異なる上側導水板を、上側導水板420の代わりに配置することもできる。 According to the roof structure 401, one end 461 of the ridge portion 421 of the upper water guide plate 420 in the orthogonal direction is positioned more perpendicularly than the one end 462 of the ridge portion 421 of the lower water guide plate 425 in the orthogonal direction. located on the other side of Therefore, like the rainwater flow path indicated by δ in FIG. 12 , rainwater is more likely to flow in the central side in the orthogonal direction on the ridge side of the roof structure 401 in the eaves ridge direction. Therefore, it is possible to effectively prevent rainwater from splashing outside from one end of the roof structure 401 in the orthogonal direction. In addition, as shown in FIG. 12 , the upper water guide plate 420 has a decorative portion 370 . However, an upper water guide plate that differs from the upper water guide plate 420 only in that the decorative portion 370 does not exist may be arranged instead of the upper water guide plate 420 .
