図1は、本実施の形態にかかる建物1の軒先構造2を示す縦断面図である。 FIG. 1 is a longitudinal sectional view showing an eaves structure 2 of a building 1 according to this embodiment.

戸建住宅や集合住宅などの建物1の軒先構造2として、建物本体3の上部に、建物本体3の外方へ軒先側の端部が突出した状態で折版屋根4を設置する。そして、折版屋根4の軒先側の端部の位置の下方(ほぼ真下)に、庇アーム5を介して軒樋7を設置する。庇アーム5の軒先側の端部に、軒樋7を外側から覆う軒先化粧カバー8を取付ける。軒先化粧カバー8の上端部と折版屋根4の軒先側の端部との間に庇カバー9を設ける。 As an eaves structure 2 of a building 1 such as a detached house or collective housing, a folded roof 4 is installed on the upper part of a building body 3 with the edge of the eaves projecting outward from the building body 3. - 特許庁Then, an eaves gutter 7 is installed via an eaves arm 5 below (almost directly below) the edge of the folded roof 4 on the eaves side. An eaves edge decorative cover 8 for covering the eaves gutter 7 from the outside is attached to the end of the eaves arm 5 on the eaves edge side. An eaves cover 9 is provided between the upper end of the eaves decorative cover 8 and the end of the folded roof 4 on the eaves side.

ここで、建物1は、どのような構造のものであっても良いが、この実施例では、ユニット建物11としている。ユニット建物11は、工場で予め製造されたほぼ直方体状の建物ユニット12を建築現場へ搬送して、建築現場で組み立てることにより、短期間のうちに建物1を構築できるようにしたものである。建物ユニット12には、鋼製のもの(鋼製ユニット)や木製のもの(木質系ユニット)など存在しているが、この実施例では、鋼製のものとしている。鋼製の建物ユニット12は、4本の柱の上端部間を4本の天井梁14で矩形状に連結し、4本の柱の下端部間を4本の床梁で矩形状に連結してなるボックスラーメン構造のユニットフレームを有している。 Although the building 1 may have any structure, it is a unit building 11 in this embodiment. A unit building 11 is constructed in a short period of time by transporting substantially rectangular parallelepiped building units 12 previously manufactured in a factory to a construction site and assembling them at the construction site. The building units 12 include those made of steel (steel units) and those made of wood (woody units). In this embodiment, the building units are made of steel. The steel building unit 12 connects the upper ends of four pillars in a rectangular shape with four ceiling beams 14, and connects the lower ends of the four pillars in a rectangular shape with four floor beams. It has a unit frame with a box frame structure.

建物本体3は、複数の建物ユニット12によって構成される。図では、最上階の建物ユニット12の天井梁14が示されている。最上階の建物ユニット12の天井梁14の外側には外壁21を構成する外壁パネルが取付けられている。外壁21は、その上端部が、ほぼ天井梁14の下部の位置まで延ばされている。 The building body 3 is composed of a plurality of building units 12 . In the figure, the ceiling beams 14 of the building unit 12 on the top floor are shown. Outside the ceiling beams 14 of the building unit 12 on the top floor, an exterior wall panel constituting an exterior wall 21 is attached. The outer wall 21 has its upper end extending almost to a position below the ceiling beam 14 .

折版屋根4は、鋼板を波型に折り曲げた屋根材である。折版屋根4は、軒元側から軒先側へ向かって下り勾配に設置される。波型の凹凸部は、軒元側から軒先側へ向かって延びるように形成される。折版屋根4は、最上階の建物ユニット12の天井梁14の上部に、ドリルビスなどの固定具23を用いて上下方向に固定されたタイトフレーム22と呼ばれる取付金具を介して取付けられる。 The folded roof 4 is a roof material formed by bending a steel plate into a corrugated shape. The folded roof 4 is installed with a downward slope from the eaves side to the eaves edge side. The corrugated uneven portion is formed so as to extend from the eaves side toward the eaves edge side. The folded roof 4 is attached to the upper part of the ceiling beams 14 of the building unit 12 on the top floor via mounting brackets called tight frames 22 that are vertically fixed using fasteners 23 such as drill screws.

庇アーム5は、外壁21の上端部よりも僅かに高い位置から建物本体3の外方へ向けてほぼ水平に延びる支持部材であり、紙面と直交する方向に間隔を有して複数設けられる。庇アーム5は、上記した天井梁14の側面にボルト、ナットなどの固定具24を用いて横方向に固定される。 The eaves arms 5 are support members that extend substantially horizontally outward from the building body 3 from a position slightly higher than the upper end of the outer wall 21, and are provided in plurality at intervals in a direction perpendicular to the plane of the drawing. The eaves arm 5 is laterally fixed to the side surface of the ceiling beam 14 using fasteners 24 such as bolts and nuts.

庇アーム5の下部には、ほぼ水平な軒天井25が、紙面と直交する方向に設置される。軒天井25は、例えば、ケイカル板などの断熱板26や、塩ビ鋼板などの軒天井パネル27などで構成することができる。断熱板26や軒天井パネル27は、受金具28などを用いて、庇アーム5の長手方向の両端部を庇アーム5の下面に取付けられる。 A substantially horizontal eaves 25 is installed below the eaves arm 5 in a direction orthogonal to the plane of the drawing. The eaves 25 can be composed of, for example, a heat insulating plate 26 such as a silica plate, an eaves panel 27 such as a vinyl chloride steel plate, or the like. The heat insulating plate 26 and the eaves panel 27 are attached to the lower surface of the eaves arm 5 at both longitudinal ends of the eaves arm 5 using brackets 28 or the like.

軒樋7は、折版屋根4に降った雨水Xを集める集水部材であり、また、集めた雨水Xを導く導水部材である。軒樋7は、折版屋根4の軒先側の端部に沿って紙面と直交する方向に延ばされる。軒樋7は、底面31と、底面31の前後(軒先側および建物1側)の縁部からほぼ上方へ立ち上がる前後の立上部32,33とを有するほぼU字状断面のものとされる。 The eaves gutter 7 is a water collecting member for collecting rainwater X falling on the folded roof 4, and is a water guiding member for guiding the collected rainwater X. The eaves gutter 7 extends along the edge of the folded roof 4 on the eaves side in a direction perpendicular to the plane of the drawing. The eaves gutter 7 has a substantially U-shaped cross section having a bottom surface 31 and front and rear rising portions 32 and 33 rising substantially upward from the front and rear edges of the bottom surface 31 (the eaves side and the building 1 side).

軒樋7は、折版屋根4の軒先側の端部の位置の下方で、かつ、庇アーム5の中間部(建物1寄りの位置)の上部に設置される。軒樋7は、庇アーム5の上面に、軒樋受具34を用いて保持固定される。 The eaves gutter 7 is installed below the end of the folded roof 4 on the eaves side and above the intermediate portion of the eaves arm 5 (position near the building 1). The eaves gutter 7 is held and fixed to the upper surface of the eaves arm 5 using eaves gutter receivers 34 .

軒樋7は、延設方向に所要の排水勾配を有して設置され、排水勾配の下流側には、縦樋が接続される。また、排水勾配の上流側には、オーバーフロー樋35が設けられる。このオーバーフロー樋35は、軒樋7内の雨水Xの水位が所定値以上となったときに、雨水Xを真下へ向かってオーバーフローさせるものである。 The eaves gutter 7 is installed with a required drainage gradient in the extending direction, and a downpipe is connected to the downstream side of the drainage gradient. Also, an overflow gutter 35 is provided on the upstream side of the drainage gradient. The overflow gutter 35 causes the rainwater X to overflow directly downward when the water level of the rainwater X in the eaves gutter 7 exceeds a predetermined value.

この実施例では、オーバーフロー樋35は、上部部材36と下部部材37とに上下分割されている。上部部材36と下部部材37とは、それぞれ別々に取付けられる。 In this embodiment, the overflow trough 35 is vertically divided into an upper member 36 and a lower member 37 . Upper member 36 and lower member 37 are attached separately.

上部部材36は、ほぼ漏斗状の部材とされて、軒樋7の側に、軒樋7の底面31を上下に貫通した状態で取付けられる。ほぼ漏斗状の上部部材36は、軒樋7の底面31よりも上側に流入口36aを有し、軒樋7の底面31よりも下側に流出口36bを有している。流入口36aは、軒樋7の内部の建物1側の立上部33よりも低い位置に設けられる。流出口36bは、流入口36aが設けられた上部部材36の上側の部分よりも小径の筒状となっている。 The upper member 36 is a substantially funnel-shaped member and is attached to the side of the eaves gutter 7 so as to vertically penetrate the bottom surface 31 of the eaves gutter 7 . A substantially funnel-shaped upper member 36 has an inlet 36 a above the bottom surface 31 of the eaves gutter 7 and an outlet 36 b below the bottom surface 31 of the eaves gutter 7 . The inflow port 36 a is provided at a position lower than the rising portion 33 on the building 1 side inside the eaves gutter 7 . The outflow port 36b has a tubular shape with a smaller diameter than the upper portion of the upper member 36 where the inflow port 36a is provided.

上部部材36が取付けられることで、軒樋7は、底面31が、庇アーム5の上面よりも高い位置に配置される。これにより、軒樋7の下側を通して換気を行い易くすることなどができる。 By attaching the upper member 36 , the bottom surface 31 of the eaves gutter 7 is arranged at a position higher than the top surface of the eaves arm 5 . This makes it easier to ventilate through the lower side of the eaves gutter 7. - 特許庁

下部部材37は、上部部材36の流出口36bから流出された雨水Xを受ける受容器とされて、軒天井25の側に取付けられる。受容器状の下部部材37は、軒天井25の上側に受入口37aを有し、軒天井25の下側に排出口37bを有している。受入口37aの内部には、上部部材36の流出口36bが上側から挿入配置される。受入口37aは、上部部材36の上側の部分よりも大径とされており、上部部材36からの雨水Xを溜めつつ排出口37bから所定量ずつ排出するようになっている。 The lower member 37 serves as a receiver for receiving the rainwater X discharged from the outlet 36b of the upper member 36, and is attached to the eaves 25 side. A receptacle-like lower member 37 has an inlet 37a above the eaves 25 and an outlet 37b below the eaves 25. As shown in FIG. The outflow port 36b of the upper member 36 is inserted from above into the receiving port 37a. The receiving port 37a has a diameter larger than that of the upper portion of the upper member 36, and collects the rainwater X from the upper member 36 while discharging it from the discharging port 37b by a predetermined amount.

軒先化粧カバー8は、取付金具41を介して庇アーム5の先端部にビスなどの取付具42で取付けられる。取付金具41は、主に、紙面と平行な面を有する金属板などで構成されており、庇アーム5の先端部の位置から、折版屋根4の軒先側の端部の頂部とほぼ同じかそれよりも高くなるように上方へ延ばされている。 The edge of the eaves decorative cover 8 is attached to the tip of the eaves arm 5 with attachments 42 such as screws through attachments 41 . The mounting bracket 41 is mainly composed of a metal plate or the like having a surface parallel to the plane of the paper, and is positioned approximately the same as the top of the edge of the folded roof 4 on the eaves side from the tip of the eaves arm 5 . It is extended upwards to be higher than it.

庇カバー9は、軒樋7の上部を上方から覆う部材であり、軒先化粧カバー8や取付金具41の上端部またはその近傍と、折版屋根4の軒先側の端部またはその近傍との間を覆うように架設されて、ビスなどの取付具43で軒先化粧カバー8や取付金具41や折版屋根4の上面に取付けられる。折版屋根4の上面は、詳しくは、折版屋根4の凹凸部の凸部の頂面の上面となる。 The eaves cover 9 is a member that covers the upper part of the eaves gutter 7 from above, and is between the upper end of the eaves decorative cover 8 or the mounting bracket 41 or its vicinity and the edge of the folded roof 4 on the eaves side or its vicinity. and attached to the upper surface of the eaves decorative cover 8, the mounting bracket 41, and the folded roof 4 with mounting brackets 43 such as screws. More specifically, the upper surface of the folded roof 4 is the upper surface of the top surface of the convex portion of the uneven portion of the folded roof 4 .

そして、庇カバー9や軒先化粧カバー8や軒天井25などで軒樋7の周囲を囲むことにより、軒樋7の周囲に所要の密閉性を有する空間が形成される。そのため、この空間や、この空間につながる建物1の内部には換気を行う必要が生じる。 By surrounding the eaves gutter 7 with the eaves cover 9, the eaves edge decorative cover 8, the eaves ceiling 25, etc., a space having a required airtightness is formed around the eaves gutter 7. - 特許庁Therefore, it is necessary to ventilate this space and the interior of the building 1 connected to this space.

なお、庇カバー9の折版屋根4側の端部には、ほぼ下方へ屈曲する屈曲部45を設けることができる。屈曲部45は、折版屋根4の凹凸部の形状に合わせた凹凸形状とすることができる。屈曲部45は、庇アーム5の延設方向に対し、軒樋7の建物1側の立上部33とほぼ同じ位置か、それよりも若干軒先寄りの位置に形成される。 At the end of the eaves cover 9 on the side of the folded roof 4, a bent portion 45 that bends substantially downward can be provided. The bent portion 45 can have an uneven shape that matches the shape of the uneven portion of the folded roof 4 . The bent portion 45 is formed at a position that is substantially the same as the rising portion 33 of the eaves gutter 7 on the side of the building 1 with respect to the extending direction of the eaves arm 5, or a position that is slightly closer to the eaves.

そして、上記のような基本的または全体的な構成に対し、この実施例は、以下のような構成を備えることができる。 In addition to the basic or overall configuration as described above, this embodiment can have the following configuration.

(1)軒樋7の建物1側の立上部33の上縁部と、折版屋根4の下面との間に、止水材51を設ける。また、軒先化粧カバー8の、少なくとも庇アーム5の下面よりも高い位置に、換気部52,53を設けるようにする。 (1) A water stop material 51 is provided between the upper edge of the rising portion 33 of the eaves gutter 7 on the building 1 side and the lower surface of the folded roof 4 . Further, ventilation parts 52 and 53 are provided at positions of the eaves decorative cover 8 at least higher than the lower surface of the eaves arm 5.例文帳に追加

ここで、軒樋7は、軒先側の立上部32を、建物1側の立上部33、および、折版屋根4の軒先側の端部の下面よりも高くなるように上へ延ばしている。これにより、折版屋根4を流下した雨水Xが、軒樋7を越えることが防止され、確実に軒樋7に雨水Xを集水することができる。 Here, the eaves gutter 7 extends the rising portion 32 on the eaves side upward so as to be higher than the rising portion 33 on the building 1 side and the lower surface of the edge of the folded roof 4 on the eaves side. As a result, the rainwater X flowing down the folded roof 4 is prevented from going over the eaves gutter 7, and the rainwater X can be reliably collected in the eaves gutter 7. - 特許庁

そして、軒樋7の建物1側の立上部33を、折版屋根4の下面へ向かって、折版屋根4の下面に僅かに到達しない程度の長さとなるように上へ延ばしている。これにより、軒樋7の建物1側の立上部33の上縁部と、折版屋根4の下面との間に止水材51を設けることが可能になる。 A rising part 33 of the eaves gutter 7 on the building 1 side is extended upward toward the lower surface of the folded roof 4 so as to have a length that does not reach the lower surface of the folded roof 4. - 特許庁This makes it possible to provide the water stop material 51 between the upper edge of the rising portion 33 of the eaves gutter 7 on the building 1 side and the lower surface of the folded roof 4 .

止水材51は、発泡系の材料などを用いることができる。止水材51は、軒樋7の建物1側の立上部33の上縁部に沿って紙面と直交する方向に延ばされる。止水材51の下面は、軒樋7の建物1側の立上部33の上縁部に粘着剤や接着剤などによって固定することができる。止水材51の上面は、折版屋根4の下面に当接される。止水材51の上面は、折版屋根4の下面に粘着剤や接着剤などによって固定することができる。折版屋根4の下面は、詳しくは、折版屋根4の凹凸部の凹部の底面の下面となる。 A foaming material or the like can be used for the water stop material 51 . The water stop material 51 extends in a direction perpendicular to the plane of the drawing along the upper edge of the upright portion 33 of the eaves gutter 7 on the building 1 side. The lower surface of the water stop material 51 can be fixed to the upper edge of the upright portion 33 of the eaves gutter 7 on the building 1 side with an adhesive or adhesive. The upper surface of the water stop material 51 is brought into contact with the lower surface of the folded roof 4 . The upper surface of the water stop material 51 can be fixed to the lower surface of the folded roof 4 with an adhesive, an adhesive, or the like. The lower surface of the folded roof 4 is, more specifically, the lower surface of the bottom surface of the concave portion of the uneven portion of the folded roof 4 .

軒先化粧カバー8は、上下方向に対し複数に分割されている。例えば、軒先化粧カバー8は、上部カバー55と中間カバー56と下部カバー57とに3分割されている。 The eaves edge decorative cover 8 is divided into a plurality of parts in the vertical direction. For example, the eaves decorative cover 8 is divided into an upper cover 55 , an intermediate cover 56 and a lower cover 57 .

そして、上部カバー55の下端部分を、中間カバー56の上端部分の上側に、隙間58を有して重ねて配置することにより、隙間58の部分に第一の換気部52が形成される。第一の換気部52は、軒樋7の軒先側の立上部32の上縁部とほぼ同じかそれよりも高い位置に設けることができる。第一の換気部52は、風雨が入り込み難いようにラビリンス形状にすることができる。この実施例では、上部カバー55の下端部分を外側へ向けて下り勾配や下向きなどに屈曲し、中間カバー56の上端部分を建物1側へ向けて上り勾配に屈曲することで、隙間58をラビリンス形状にしている。 By placing the lower end portion of the upper cover 55 on top of the upper end portion of the intermediate cover 56 with a gap 58 therebetween, the first ventilation section 52 is formed in the gap 58 . The first ventilation part 52 can be provided at a position substantially equal to or higher than the upper edge part of the rising part 32 on the eaves edge side of the eaves gutter 7 . The first ventilation part 52 can be labyrinth-shaped so that wind and rain cannot easily enter. In this embodiment, the lower end portion of the upper cover 55 is bent outward toward a downward slope or downward, and the upper end portion of the intermediate cover 56 is bent upward toward the building 1 side, thereby forming a labyrinthine gap 58. shape.

また、中間カバー56の下端部分を、下部カバー57の上端部分の外側に、隙間59を有して重ねて配置することにより、隙間59の部分に第二の換気部53が形成される。第二の換気部53は、庇アーム5の下面と上面との間の位置に設けることができる。第二の換気部53は、風雨が入り込み難いようにラビリンス形状にすることができる。この実施例では、中間カバー56の下端部分を建物1側へ向けてほぼ水平に屈曲し、下部カバー57の上端部分を外側へ向けてほぼ水平に屈曲することで隙間59をラビリンス形状にしている。 Further, by arranging the lower end portion of the intermediate cover 56 on the outside of the upper end portion of the lower cover 57 with a gap 59 therebetween, the second ventilation portion 53 is formed in the gap 59 . The second ventilation part 53 can be provided at a position between the lower surface and the upper surface of the eaves arm 5 . The second ventilation part 53 can be labyrinth-shaped so as to prevent wind and rain from entering. In this embodiment, the lower end portion of the intermediate cover 56 is bent substantially horizontally toward the building 1 side, and the upper end portion of the lower cover 57 is bent substantially horizontally toward the outside, thereby forming the gap 59 into a labyrinth shape. .

その他に、下部カバー57と、軒天井25の軒先側の端部との間には、第三の換気部54を形成しても良い。第三の換気部54は、庇アーム5の下面よりも低い位置に形成される。この第三の換気部54は、既存のものと同様のものである。 In addition, a third ventilation section 54 may be formed between the lower cover 57 and the edge of the eaves 25 on the eaves side. The third ventilation part 54 is formed at a position lower than the lower surface of the eaves arm 5 . This third ventilation part 54 is similar to the existing one.

<作用>以下、この実施例の作用について説明する。 <Action> The action of this embodiment will be described below.

この実施例にかかる建物1の軒先構造2では、建物本体3の上部に、建物本体3の外方へ軒先側の端部が突出した状態で折版屋根4を設置し、折版屋根4の軒先側の端部の位置の下方に、庇アーム5を介して軒樋7を設置している。これにより、折版屋根4に降った雨水Xは、折版屋根4を流下して軒樋7に集められる。軒樋7に集められた雨水Xは、軒樋7の下流側に設けられる縦樋を介して下水道などへ排出される。また、軒樋7に詰まりなどのトラブルが発生して、軒樋7に所定量以上の雨水Xが溜まった場合には、溜まった雨水Xは、オーバーフロー樋35から真下へ向けて排水される。これにより、溜まった雨水Xが屋内側へ流入することが防止されると共に、住人は、軒樋7のトラブルを直接的に知ることができる。 In the eaves structure 2 of the building 1 according to this embodiment, a folded roof 4 is installed on the upper part of the building body 3 with the edge of the eaves protruding outward from the building body 3. An eaves gutter 7 is installed via an eaves arm 5 below the position of the end on the eaves edge side. As a result, the rainwater X falling on the folded roof 4 flows down the folded roof 4 and is collected in the eaves gutter 7. - 特許庁The rainwater X collected in the eaves gutter 7 is discharged to a sewage system or the like through a downpipe provided downstream of the eaves gutter 7 . Further, when a trouble such as clogging occurs in the eaves gutter 7 and rainwater X exceeding a predetermined amount accumulates in the eaves gutter 7, the collected rainwater X is drained directly downward from the overflow gutter 35.例文帳に追加As a result, the collected rainwater X is prevented from flowing indoors, and the residents can directly know the trouble of the eaves gutter 7. - 特許庁

そして、庇アーム5の軒先側の端部に、軒樋7を外側から覆う軒先化粧カバー8を取付け、軒先化粧カバー8の上端部と折版屋根4の軒先側の端部との間に庇カバー9を設ける。これにより、軒樋7を軒先化粧カバー8や庇カバー9で覆って外部から見え難くすることができる。そのため、軒先構造2の外観品質を向上することができる。軒先化粧カバー8や庇カバー9の内側などに対する換気は、軒先化粧カバー8の上部や中間部に設けた換気部52,53によって行うことができる。 An eaves decorative cover 8 is attached to the end of the eaves arm 5 on the eaves side to cover the eaves gutter 7 from the outside. A cover 9 is provided. Thus, the eaves gutter 7 can be covered with the eaves edge decorative cover 8 or the eaves cover 9 to make it difficult to see from the outside. Therefore, the appearance quality of the eaves structure 2 can be improved. The inside of the eaves decorative cover 8 and the eaves cover 9 can be ventilated by ventilation units 52 and 53 provided in the upper part and the middle part of the eaves decorative cover 8. - 特許庁

この際、図2の比較例に示すような既存の軒先構造2では、タイトフレーム22と呼ばれる取付金具の近傍に、図3(a)~(c)に示すような(折版屋根4の凹凸部の形状に合わせた)山型の軒先面戸71を設けて、軒先面戸71によって折版屋根4の軒先側の端部から下側へ回り込んだ伝い水を切ったり、風雨をブロックしたりさせているので、その分、部品コストや取付けの手間がかかっている。 At this time, in the existing eaves edge structure 2 as shown in the comparative example of FIG. A mountain-shaped eaves surface door 71 (matching the shape of the roof) is provided, and the eaves surface door 71 cuts off the water that flows downward from the edge of the eaves side of the folded roof 4 and blocks wind and rain. Since it is made to be attached, the parts cost and installation are troublesome.

また、図2の比較例のものは、軒先化粧カバー8の下部のみにしか換気部(第三の換気部54に相当)が設けられていなかったので、換気効率が良くなかった。 Further, in the comparative example shown in FIG. 2, the ventilation section (corresponding to the third ventilation section 54) was provided only in the lower part of the eaves decorative cover 8, so the ventilation efficiency was not good.

<効果>この実施例によれば、以下のような効果を得ることができる。 <Effects> According to this embodiment, the following effects can be obtained.

(効果 1)軒先構造2では、軒樋7の建物1側の立上部33の上縁部と、折版屋根4の下面との間に、止水材51を設けると共に、軒先化粧カバー8の、庇アーム5の下面よりも高い位置に、換気部52,53を設けても良い。 (Effect 1) In the eaves structure 2, a water stop material 51 is provided between the upper edge of the rising portion 33 of the eaves gutter 7 on the building 1 side and the lower surface of the folded roof 4, and the eaves decorative cover 8 is provided. , ventilation parts 52 and 53 may be provided at positions higher than the lower surface of the eaves arm 5. - 特許庁

これにより、折版屋根4の軒先側の端部から折版屋根4の裏面へ回り込んだ伝い水を、軒樋7の建物1側の立上部33の上縁部の止水材51で切ることができる。よって、伝い水を切るための軒先面戸71をなくすことができる。 As a result, the water running down from the edge of the eaves side of the folded roof 4 to the rear surface of the folded roof 4 is cut off by the water stop material 51 at the upper edge of the rising part 33 of the eaves gutter 7 on the building 1 side. be able to. Therefore, it is possible to eliminate the eaves front door 71 for cutting running water.

また、風雨は、軒先化粧カバー8や庇カバー9によってブロックすることができる。そして、換気は、矢印Yで示すように、軒先化粧カバー8の、庇アーム5の下面よりも高い位置に設けた単数または複数の換気部52,53によって行わせることができる。よって、軒先面戸71をなくしても、換気効率を向上しつつ、水切り機能と、風雨をブロックする機能とを軒先構造2に持たせることができる。 Wind and rain can be blocked by the eaves decorative cover 8 and the eaves cover 9. - 特許庁Ventilation can be performed by one or a plurality of ventilation portions 52 and 53 provided at a position higher than the lower surface of the eaves arm 5 of the eaves decorative cover 8 as indicated by an arrow Y. Therefore, even if the eaves facing door 71 is eliminated, the eaves structure 2 can have a drainage function and a function of blocking wind and rain while improving the ventilation efficiency.

しかも、軒先化粧カバー8の上部に第一の換気部52を設け、軒先化粧カバー8の中間部に第二の換気部53を設けて、少なくとも上部と中間部との二箇所の位置で換気を行わせるようにすることで、換気効率をより高めることができる。この実施例では、上側の第一の換気部52から入った空気は、軒樋7の下側を通って、軒樋7の背面側(建物1側の立上部33の裏側)から建物本体3の内部へと通される。同様に、中間部に第二の換気部53から入った空気は、軒樋7の下側を通って、軒樋7の背面側(建物1側の立上部33の裏側)から建物本体3の内部へと通される。 Moreover, the first ventilation part 52 is provided in the upper part of the eaves decorative cover 8, and the second ventilation part 53 is provided in the middle part of the eaves decorative cover 8, so that ventilation is performed at least at two positions, the upper part and the middle part. By doing so, the ventilation efficiency can be further enhanced. In this embodiment, the air entering from the upper first ventilation section 52 passes through the lower side of the eaves gutter 7 to the building body 3 from the back side of the eaves gutter 7 (the back side of the upright section 33 on the building 1 side). is passed into the interior of the Similarly, the air entering the intermediate part from the second ventilation part 53 passes through the lower side of the eaves gutter 7 and passes through the back side of the eaves gutter 7 (the back side of the rising part 33 on the building 1 side) to the building body 3. passed inside.
