【発明の属する技術分野】
本発明は、縦葺き屋根材の嵌合部分の化粧を行なうための建築部材である桟鼻（サンバナ）に関するものである。
【０００２】
【従来の技術】
従来より、野地板等の屋根下地の上に横方向（例えば、妻方向）に複数枚接続して葺かれる縦葺き屋根材が提案されている。この縦葺き屋根材Ａは図５（ａ）（ｂ）に示すように、略平板状もしくは小波板形状（同一間隔で連続的に凹と凸の繰り返し模様を有する形状）に形成される屋根材本体１の一方の側端部（屋根下地４の傾斜方向と略平行に配置される端部であって、例えば、屋根の軒棟方向と平行な端部）の略全長に亘って嵌合部２を上側に突出させて形成すると共に屋根材本体１の他方の側端部の略全長に亘って被嵌合部３を上側に突出させて形成したものである。嵌合部２は例えば断面略逆Ｕ字状に形成されるものであり、被嵌合部３は例えば断面略逆Ｖ字状に形成することができる。また、嵌合部２及び被嵌合部３は屋根材本体１の面方向に対して略垂直な方向に立設されている。縦葺き屋根材Ａは耐食性のある金属板、例えば、塗装鋼板やめっき鋼板などを用いて形成することができる。
【０００３】
上記のように形成される縦葺き屋根材Ａは、次にようにして施工することができる。まず、縦葺き屋根材用固定具（吊子）Ｂを縦葺き屋根材Ａの被嵌合部３に上側から嵌め込んで圧接させて係合させることによって、縦葺き屋根材Ａの被嵌合部３の所定箇所に複数個の縦葺き屋根材用固定具Ｂを取り付ける。次に、屋根勾配と嵌合部２及び被嵌合部３が略平行となるようにして野地板等の屋根下地４に縦葺き屋根材Ａを載置する。次に、縦葺き屋根材Ａに取り付けられた各縦葺き屋根材用固定具Ｂを屋根下地４に釘やビスなどにより固定することによって、複数個の固定具Ｂを介して上記縦葺き屋根材Ａを屋根下地４に取り付ける。
【０００４】
次に、屋根下地４に固定された上記縦葺き屋根材Ａにこれとは別の他の縦葺き屋根材Ａが接続される。屋根下地４の上の縦葺き屋根材Ａに他の縦葺き屋根材Ａを接続するにあたっては、図６に示すように、屋根下地４に固定されている縦葺き屋根材Ａの被嵌合部３に上方から他の縦葺き屋根材Ａの嵌合部２を載せ、嵌合部２に上から力を加えることによって、他の縦葺き屋根材Ａの嵌合部２を屋根下地４の上に固定された縦葺き屋根材Ａの被嵌合部３及びこれに嵌着された縦葺き屋根材固定具Ｂの外側に嵌め込むことによって、屋根下地４に固定されている縦葺き屋根材Ａの被嵌合部３を他の縦葺き屋根材Ａの嵌合部２の内側に嵌合して縦葺き屋根材Ａ、Ａ同士を接続することができる。この後、上記一連の作業を繰り返し行なって複数枚の縦葺き屋根材Ａを屋根下地４の上に葺設することによって、図７に示すような屋根が形成されるのである。尚、図７において、２０は屋根下地４上に敷設された防水シート、２１は屋根下地４の軒側端部に取り付けられた唐草であり、防水シート２０及び唐草２１のいずれもが屋根下地４と縦葺き屋根材Ａの間に配置されるものである。
【０００５】
上記のようにして接続された縦葺き屋根材Ａにおいて、隣接する縦葺き屋根材Ａの嵌合部２と被嵌合部３の嵌合部分の軒側先端には軒先開口５が形成されるが、この軒先開口５を閉塞して化粧するために桟鼻が取り付けられている。
【０００６】
従来より、桟鼻としては外付けタイプのものと内付けタイプのものとがある。外付けタイプの桟鼻Ｃ’は表面板６の周端に取付片９を後方に向けて突設することにより形成されるものである。そして、この桟鼻Ｃ’を嵌合部２と被嵌合部３との嵌合部分に取り付けるにあたっては、まず、図１０（ａ）に示すように、唐草２１よりも軒先側に突出する縦葺き屋根材Ａの軒側端部において、屋根材本体１と嵌合部２及び被嵌合部３との境界部分に切れ目２２を入れる。次に、図１０（ｂ）に示すように、屋根材本体１の軒側端部を下側に折り返して唐草２１の軒側端部をつかみこむようにする。これにより、嵌合部２と被嵌合部３との嵌合部分の軒側端部が屋根材本体１より軒先側に突出することになる。次に、図１０（ｂ）に示すように、桟鼻Ｃ’を上記嵌合部分に軒先側から近づけて桟鼻Ｃ’の取付片９の内側に上記嵌合部分の軒側端部を嵌め込む。この後、図１０（ｃ）に示すように、取付片９の外側から嵌合部２にまでビス等の固定具２３を打ち込むことによって、嵌合部２と被嵌合部３との嵌合部分の軒側端部に桟鼻Ｃ’を固定して取り付けることができる。
【０００７】
一方、内付けタイプの桟鼻Ｃ’は底板８の上面に表面板６を立設すると共に表面板６の周端に取付片９を後方に向けて突設することにより形成されるものである。そして、この桟鼻Ｃ’を嵌合部２と被嵌合部３との嵌合部分に取り付けるにあたっては、まず、図１１（ａ）に示すように、唐草（軒先水切り）２１よりも軒先側に突出する縦葺き屋根材Ａの軒側端部において、嵌合部２及び被嵌合部３とを切除する。次に、図１１（ｂ）に示すように、唐草２１と屋根材本体１の隙間に軒先側から桟鼻Ｃ’の底板８を挿入すると共に桟鼻Ｃ’の取付片９を上記嵌合部分の軒先開口５に挿入することによって、桟鼻Ｃ’を軒先開口５に嵌め込んで装着する。次に、図１１（ｂ）に示すように、屋根材本体１の軒側端部を下側に折り返して唐草２１の軒側端部をつかみこむようにする。これにより、唐草２１と屋根材本体１の隙間が閉塞されて底板８が抜けないようになる。このようにして、嵌合部２と被嵌合部３との嵌合部分の軒側端部に桟鼻Ｃ’を固定して取り付けることができる。
【０００８】
【発明が解決しようとする課題】
しかし、上記の桟鼻Ｃ’では積雪時等において嵌合部２と被嵌合部３との嵌合部分に荷重がかかって変形が生じた場合などに軒先開口５から外れたり脱落したりすることがあった。特に、外付けタイプの桟鼻Ｃ’では積雪等による荷重で固定具２３により固定した箇所に割れが生じて脱落しやすかった。また、内付けタイプの桟鼻Ｃ’の場合、嵌合部２と被嵌合部３の軒側端部を切除しなければならず、施工に手間がかかるという問題があった。
【０００９】
本発明は上記の点に鑑みてなされたものであり、縦葺き屋根材の嵌合部と被嵌合部の嵌合部分の軒先開口から容易に外れたり脱落しないようにすることができると共に施工に手間がかからない桟鼻を提供することを目的とするものである。
【００１０】
【課題を解決するための手段】
本発明の請求項１に係る桟鼻Ｃは、屋根材本体１の一側端部に形成された嵌合部２と、屋根材本体１の他側端部に形成された被嵌合部３との嵌合部分の軒先開口５に取り付けられる桟鼻Ｃであって、屋根下地４に載置される底板８の軒側端部に軒先開口５を閉塞するための表面板６を設けると共に上記嵌合部分に挿入されて嵌合部分を支持する支持板７を底板８に立設して成ることを特徴とするものであり、支持板７により嵌合部分の軒先開口５の周縁部を支持して積雪による軒先開口５の変形を防止することができ、軒先開口５から桟鼻Ｃが外れたり脱落したりするのを防止することができるものである。また、嵌合部２及び被嵌合部３の軒側端部を切除することなく桟鼻Ｃを取り付けることができ、施工に手間がかからないようにすることができるものである。
【００１１】
また、本発明の請求項２に係る桟鼻Ｃは、請求項１に加えて、嵌合部分に挿入されて嵌合部２に固定される取付片９を表面板６に設けて成ることを特徴とするものであり、取付片９を嵌合部２に固定することによって桟鼻Ｃを強固に嵌合部分に取り付けることができ、積雪により軒先開口５から桟鼻Ｃが外れたり脱落したりするのを確実に防止することができるものである。
【００１２】
【発明の実施の形態】
以下、本発明の実施の形態を説明する。
【００１３】
図１（ａ）〜（ｄ）に本発明の桟鼻Ｃの一例を示す。この桟鼻Ｃはステンレス鋼板等の耐食性の高い金属板を例えば図４に示すような形状に打ち抜き加工し、これを折り曲げ加工（折り曲げする部分を点線で示す）して形成されるものである。桟鼻Ｃは左右に連結された一対の桟鼻半体１０により構成されている。桟鼻半体１０は平板状の底板半体１１と、底板半体１１の前端部（軒側端部）から上方に向けて突設された表面板半体１２と、底板半体１１の一方の側端部から上方に向けて突設された略楔形の支持板７とから形成されている。二つの支持板７のうち、一方の支持板７には厚み方向に貫通する係止孔３０が形成されていると共に他方の支持板７には切り起こし加工にて係止片３１が形成されている。また、表面板半体１２の周端部には複数個の挿入片１３が後方に向けて突設されていると共に表面板半体１２の周端部には上記の挿入片１３よりも長い取付片９が後方に向けて突設されている。そして、一対の桟鼻半体１０は支持板７の後端部同士が要部１４により連結されると共に二つの支持板７が外面同士を合わせた状態で結合することにより一体化されている。二つの支持板７の結合は一方の支持板７の係止孔３０に他方の支持板７の係止片３１を挿入して折り返し屈曲し、係止孔３０と係止片３１とを係止するようにして行なわれる（これをステッチという）。また、一対の桟鼻半体１０の一体化により底板半体１１が横に並んで底板８が形成されると共に表面板半体１２が横に並んで二分割可能な表面板６が形成されるものである。従って、表面板６は底板８の前端部に上方に向いて突出して形成されるものであり、また、底板８にはその略中央部を通るように二枚の支持板７が上方に向いて突出して形成されるものである。尚、上記の要部１４の位置は支持板７の下端や支持板７の上端であっても良く、また、要部１４を設けずに桟鼻半体１０が完全に分割されていても良い。
【００１４】
このように形成される桟鼻Ｃは従来と同様にして施工されるものであって、縦葺き屋根材Ａの嵌合部２とこれに隣接する他の縦葺き屋根材Ａの被嵌合部３との嵌合部分の軒側先端に形成される軒先開口５に取り付けられるものである。すなわち、まず、図２（ａ）に示すように、唐草２１よりも軒先側に突出する縦葺き屋根材Ａの軒側端部において、屋根材本体１と嵌合部２及び被嵌合部３との境界部分に切れ目２２を入れる。次に、屋根材本体１の軒側端部を下側に折り返して唐草２１の軒側端部をつかみこむようにする。これにより、嵌合部２と被嵌合部３との嵌合部分の軒側端部が屋根材本体１より軒先側に突出することになる。次に、図２（ｂ）に示すように、桟鼻Ｃを上記嵌合部分に軒先側から近づけて桟鼻Ｃの支持板７と取付片９と挿入片１３と底板８とを上記嵌合部分の軒側端部の内側に差し込むと共に表面板６を軒先開口５に嵌め込む。さらに、桟鼻Ｃの底板８を上記嵌合部分の下面開口の下側に位置させて、底板８の後端部（表面板６を設けた側と反対側の端部）を唐草２１の上に載置する。ここで、上記嵌合部分の内側に挿入された支持板７は屋根材本体１の面方向及び屋根下地４の面方向（傾斜方向）に対して略垂直に立設されるものである。この後、嵌合部２の外側から取付片９及び支持板７にまでビス（スクリュービス）等の固定具２３を打ち込む。固定具２３は上記嵌合部分の長手方向（軒棟方向）に対して両側から打ち込むようにする。このようにして図３（ａ）（ｂ）に示すように、嵌合部２と被嵌合部３との嵌合部分の軒側端部に桟鼻Ｃを固定して取り付けることができる。
【００１５】
そして、本発明では、隣接する縦葺き屋根材Ａの嵌合部２と被嵌合部３の嵌合部分の内側に挿入された支持板７で上記嵌合部分の軒先開口５の周縁部を支持することによって、積雪（氷結）による軒先開口５の変形を防止することができ、軒先開口５から桟鼻Ｃが外れたり脱落したりするのを防止することができるものである。また、嵌合部２及び被嵌合部３の軒側端部を切除することなく桟鼻Ｃを取り付けることができ、施工に手間がかからないようにすることができるものであり、施工が簡単で速く行なうことができ、また熟練作業が必要なく、さらにきれいに仕上げることができるものである。また、上記の嵌合部分の軒先開口５は開く傾向にあり、特に、嵌合部２と被嵌合部３の間に定型シールパッキンを介在させたり、縦葺き屋根材Ａをステンレス鋼板で形成したりした場合には、軒先開口５が開く傾向が大きくなるが、本発明では開いていない軒先開口５の形状に対応させて表面板６や支持板７や底板８を形成しているために、開いた軒先開口５の形状を桟鼻Ｃで矯正しながら軒先開口５に桟鼻Ｃを取り付けることができ、屋根の外観を向上させることができるものである。また、本発明の桟鼻Ｃは、屋根材本体１の軒側端部から突出した上記嵌合部分の軒側端部の下面開口を桟鼻Ｃの底板８で閉塞することができ、屋根の美観や強度を向上させることができるものである。さらに、桟鼻Ｃの底板８の後端部を唐草２１の上に載置することによって、桟鼻Ｃを唐草２１で支持することができ、桟鼻Ｃの取り付け強度を高めることができるものである。
【００１６】
また、本発明の桟鼻Ｃは図８（ａ）に示すような寄せ棟屋根４５の降り谷部４０において特に好適に用いることができる。寄せ棟屋根４５の降り谷部４０は隣接する二面の屋根４１、４１の間に形成された軒棟方向に下り傾斜する部分であり、上記屋根４１、４１に敷設された縦葺き屋根材Ａは軒側端部が降り谷部４０に臨むように位置している。そして、図８（ｂ）に示すように、降り谷部４０に臨む縦葺き屋根材Ａの屋根材本体１の軒側端部は降り谷部４０の傾斜に沿って斜めに切断して仕上げるものであり、また、嵌合部２と被嵌合部３の嵌合部分はその長手方向と直交する方向に切断されるものである。このような降り谷部４０において嵌合部２と被嵌合部３の嵌合部分の軒側端部に従来の内付けタイプの桟鼻Ｃ’を取り付けようとすると、桟鼻Ｃ’の底板８が邪魔になって屋根材本体１の軒側端部を下側に折り返すことができず、取り付けが不可能であったが、本発明の桟鼻Ｃは屋根材本体１の軒側端部を下側に折り返した後、嵌合部２と被嵌合部３の嵌合部分の軒側開口５に装着するので、屋根材本体１の軒側端部を下側に折り返す際に底板８が邪魔にならずに簡単に取り付けることができるものである。
【００１７】
尚、上記の実施の形態では係止孔３０と係止片３１の係止により二つの支持板７を結合するようにしたが、係止孔３０と係止片３１による係止の代わりに、図９（ａ）乃至（ｄ）に示すように、ビスやハトメ（パンチ）等の開き止め具１５にて両方の支持板７を結合してもよい。
【００１８】
【発明の効果】
上記のように本発明の請求項１の発明は、屋根材本体の一側端部に形成された嵌合部と、屋根材本体の他側端部に形成された被嵌合部との嵌合部分の軒先開口に取り付けられる桟鼻であって、屋根下地に載置される底板の軒側端部に軒先開口を閉塞するための表面板を設けると共に上記嵌合部分に挿入されて嵌合部分を支持する支持板を底板に立設して成ることを特徴とするものであり、支持板により嵌合部分の軒先開口の周縁部を支持して積雪による軒先開口の変形を防止することができ、軒先開口から桟鼻が外れたり脱落したりするのを防止することができるものである。また、嵌合部及び被嵌合部の軒側端部を切除することなく桟鼻を取り付けることができ、施工に手間がかからないようにすることができるものである。
【００１９】
また本発明の請求項２の発明は、嵌合部分に挿入されて嵌合部に固定される取付片を表面板に設けて成ることを特徴とするものであり、取付片を嵌合部に固定することによって桟鼻を強固に嵌合部分に取り付けることができ、積雪により軒先開口から桟鼻が外れたり脱落したりするのを確実に防止することができるものである。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nose (sannabana), which is a building member for performing makeup on a fitting portion of a roofing material.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, vertical roofing materials have been proposed in which a plurality of roofing materials are connected and roofed in a lateral direction (for example, in the direction of a wife) on a roof foundation such as a field board. As shown in FIGS. 5 (a) and 5 (b), this vertically-roofed roofing material A is a roofing material formed in a substantially flat plate shape or a small corrugated plate shape (a shape having a repeating pattern of concave and convex at the same interval and continuous). The fitting portion extends over substantially the entire length of one side end of the main body 1 (an end arranged substantially in parallel to the inclination direction of the roof base 4 and, for example, an end parallel to the eaves ridge direction of the roof). 2 is formed so as to protrude upward, and the fitted portion 3 is formed so as to protrude upward over substantially the entire length of the other side end of the roofing material main body 1. The fitting portion 2 is formed, for example, in a substantially inverted U-shaped cross section, and the fitted portion 3 can be formed, for example, in a substantially inverted V-shaped cross section. The fitting portion 2 and the fitted portion 3 are provided upright in a direction substantially perpendicular to the surface direction of the roofing material main body 1. The roofing material A can be formed using a corrosion-resistant metal plate, for example, a coated steel plate or a plated steel plate.
[0003]
The vertical roofing material A formed as described above can be constructed as follows. First, the vertical roofing material A (fitting part) B is fitted into the fitted portion 3 of the vertical roofing material A from the upper side by pressing and engaging the vertical roofing material A with the fitting. A plurality of fixing devices B for roofing materials are attached to predetermined portions of the part 3. Next, the vertically-roofed roofing material A is placed on the roof foundation 4 such as a field board so that the roof slope is substantially parallel to the fitting portion 2 and the fitted portion 3. Next, by fixing each fixing device B for vertical roofing materials attached to the vertical roofing material A to the roof foundation 4 with nails or screws, the vertical roofing material is fixed via a plurality of fixing devices B. A is attached to the roof base 4.
[0004]
Next, another vertical roofing material A other than this is connected to the vertical roofing material A fixed to the roof foundation 4. When connecting another vertical roofing material A to the vertical roofing material A on the roof foundation 4, the fitting portion of the vertical roofing material A fixed to the roof foundation 4 as shown in FIG. The fitting portion 2 of another roofing material A is placed on the roof 3 from above, and a force is applied to the fitting portion 2 from above, so that the fitting portion 2 of the other roofing material A is placed on the roof foundation 4. The roofing material A fixed to the roof foundation 4 by being fitted to the fitted portion 3 of the roofing material A fixed to the roof and the fixing device B for the roofing material fitted thereto. Can be connected to the inside of the fitting portion 2 of another roofing material A to connect the roofing materials A with each other. Thereafter, the above-described series of operations are repeatedly performed to lay a plurality of vertically roofing members A on the roof foundation 4, thereby forming a roof as shown in FIG. In FIG. 7, reference numeral 20 denotes a waterproof sheet laid on the roof foundation 4, reference numeral 21 denotes an arabesque attached to the eaves end of the roof foundation 4, and both the waterproof sheet 20 and the arabesque 21 are the roof foundation 4 And the vertical roof material A.
[0005]
In the vertical roof material A connected as described above, an eave opening 5 is formed at the eave-side end of the fitting portion between the fitting portion 2 and the fitted portion 3 of the adjacent vertical roof material A. However, a nose is attached to close and close the eaves opening 5.
[0006]
Conventionally, there are an external type and an internal type as a nose. The external type nose C ′ is formed by projecting a mounting piece 9 toward the rear at the peripheral end of the surface plate 6. When attaching the nose C ′ to the fitting portion between the fitting portion 2 and the fitted portion 3, first, as shown in FIG. At the eaves-side end of the roofing material A, a cut 22 is made at the boundary between the roofing material body 1 and the fitting portion 2 and the fitted portion 3. Next, as shown in FIG. 10 (b), the eaves-side end of the roofing material main body 1 is folded down so as to grab the eaves-side end of the arabesque 21. As a result, the eave-side end of the fitting portion between the fitting portion 2 and the fitted portion 3 projects toward the eaves side from the roofing material main body 1. Next, as shown in FIG. 10B, the nose C ′ is brought closer to the fitting portion from the eaves side, and the eave-side end of the fitting portion is fitted inside the mounting piece 9 of the nose C ′. Put in. Thereafter, as shown in FIG. 10 (c), a fastener 23 such as a screw is driven from the outside of the mounting piece 9 to the fitting portion 2 to fit the fitting portion 2 and the fitted portion 3 together. The nose C 'can be fixedly attached to the eaves end of the part.
[0007]
On the other hand, the internal type nose C 'is formed by erecting the surface plate 6 on the upper surface of the bottom plate 8 and projecting the mounting piece 9 rearward at the peripheral end of the surface plate 6. . When attaching the nose C ′ to the fitting portion between the fitting portion 2 and the fitted portion 3, first, as shown in FIG. The fitting portion 2 and the fitted portion 3 are cut off at the eaves-side end of the vertically-roofed roofing material A protruding from the roof. Next, as shown in FIG. 11B, the bottom plate 8 of the nose C ′ is inserted into the gap between the arabesque 21 and the roofing material main body 1 from the eaves side, and the mounting piece 9 of the nose C ′ is connected to the fitting portion. The nose C 'is fitted into the eaves opening 5 by being inserted into the eaves opening 5. Next, as shown in FIG. 11B, the eaves-side end of the roofing material main body 1 is turned downward so that the eaves-side end of the arabesque 21 is grasped. Thereby, the gap between the arabesque 21 and the roofing material main body 1 is closed, so that the bottom plate 8 does not come off. In this manner, the nose C ′ can be fixed and attached to the eaves-side end of the fitting portion between the fitting portion 2 and the fitted portion 3.
[0008]
[Problems to be solved by the invention]
However, in the above-mentioned nose C ′, when a load is applied to the fitting portion between the fitting portion 2 and the fitted portion 3 at the time of snow or the like and the load is deformed, the nose C ′ comes off from the eave opening 5 or falls off. There was something. In particular, in the case of the external type nose C ′, the portion fixed by the fixture 23 was easily cracked due to the load due to snowfall or the like, and it was easy to fall off. Further, in the case of the internal type nose C ′, the eaves-side end of the fitting part 2 and the fitting part 3 must be cut off, and there is a problem that the construction is troublesome.
[0009]
The present invention has been made in view of the above points, and it is possible to prevent the roof from being easily detached from the eaves opening of the fitting part of the fitting part of the vertical roofing material and the fitting part of the fitting part, and to perform the construction. It is an object of the present invention to provide a nose that does not require much labor.
[0010]
[Means for Solving the Problems]
The nose C according to claim 1 of the present invention includes a fitting portion 2 formed at one end of the roof material main body 1 and a fitted portion 3 formed at the other end of the roof material main body 1. And a surface plate 6 for closing the eaves opening 5 at the eaves-side end of the bottom plate 8 placed on the roof foundation 4, the nose C being attached to the eaves opening 5 at the fitting portion. A support plate (7) inserted into the fitting portion and supporting the fitting portion is provided upright on the bottom plate (8), and the supporting plate (7) supports the periphery of the eaves opening (5) at the fitting portion. Thus, deformation of the eaves opening 5 due to snow accumulation can be prevented, and the nose C can be prevented from coming off or falling off from the eaves opening 5. In addition, the nose C can be attached without cutting off the eaves-side end of the fitting portion 2 and the fitted portion 3, so that the construction can be performed without any trouble.
[0011]
A nose C according to a second aspect of the present invention, in addition to the first aspect, is characterized in that a mounting piece 9 inserted into the fitting portion and fixed to the fitting portion 2 is provided on the surface plate 6. By fixing the mounting piece 9 to the fitting portion 2, the nose C can be firmly attached to the fitting portion, and the nose C may come off or fall off from the eaves opening 5 due to snow. Can be reliably prevented.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described.
[0013]
1A to 1D show an example of a nose C of the present invention. The nose C is formed by punching a metal plate having high corrosion resistance such as a stainless steel plate into a shape as shown in FIG. 4, for example, and bending the same (the bent portion is indicated by a dotted line). The nose C is constituted by a pair of nose halves 10 connected left and right. The nose half 10 is a flat bottom half 11, a front half 12 projecting upward from the front end (eave side end) of the bottom half 11, and one of the bottom half 11. And a substantially wedge-shaped support plate 7 projecting upward from the side end of the support plate 7. Of the two support plates 7, one support plate 7 has a locking hole 30 penetrating in the thickness direction, and the other support plate 7 has a locking piece 31 formed by cutting and raising. I have. A plurality of insertion pieces 13 are protruded rearward from the peripheral end of the face plate half 12, and are attached to the peripheral end of the face plate half 12 so as to be longer than the insert 13.

However, in the present invention, the surface plate 6, the support plate 7, and the bottom plate 8 are formed in accordance with the shape of the eaves opening 5 which is not opened in the present invention. While correcting the shape of the open eaves opening 5 with the nose C, the nose C can be attached to the eaves opening 5, and the appearance of the roof can be improved. Further, in the nose C of the present invention, the lower surface opening of the eave-side end of the fitting portion protruding from the eave-side end of the roofing material main body 1 can be closed by the bottom plate 8 of the nose C, and Aesthetic appearance and strength can be improved. Further, by placing the rear end of the bottom plate 8 of the nose C on the arabesque 21, the nose C can be supported by the arabesque 21 and the mounting strength of the nose C can be increased. is there.
[0016]
Also, the nose C of the present invention can be particularly suitably used in the descending valley portion 40 of the ridge roof 45 as shown in FIG. The descending valley portion 40 of the ridge roof 45 is a portion formed between the two adjacent roofs 41, 41 and inclined downward in the direction of the eaves ridge, and the vertical roofing material A laid on the roofs 41, 41 Is located such that the eaves-side end descends and faces the valley portion 40. Then, as shown in FIG. 8B, the eaves-side end of the roofing material body 1 of the vertically-roofed roofing material A facing the descending valley portion 40 is cut and finished obliquely along the slope of the descending valley portion 40. The fitting portion between the fitting portion 2 and the fitted portion 3 is cut in a direction orthogonal to the longitudinal direction. If it is attempted to attach a conventional internal type nose C ′ to the eaves-side end of the fitting portion between the fitting portion 2 and the fitted portion 3 in such a descending valley portion 40, the bottom plate of the nose C ′ 8 could disturb the eaves-side end of the roofing material main body 1 from being folded back downward, and installation was not possible. Is folded down, and then the eaves-side opening 5 of the fitting portion between the fitting portion 2 and the fitted portion 3 is attached to the eaves-side opening 5. Can be easily attached without disturbing.
