Description

【０００１】
【発明の属する技術分野】
本発明は、屋根材を葺いて構成した屋根上に這わせる這樋を屋根材に取付けるための技術に関するものである。
【０００２】
【従来の技術】
従来から２階建ての建物のような多層階の建物において各階の屋根に降った雨水を排水するには、上階の屋根の雨水を上階の屋根の軒先に配設した上階の軒樋に流し、これを上階の軒樋に接続した上階の縦樋に流し、更に、上階の縦樋から該上階の縦樋の下端に後端を接続し且つ下階の屋根上に這わせた這樋に流し、這樋の前端から下階の屋根の軒先に配設した下階の軒樋に流し、同時に下階の屋根の雨水を下階の軒樋に流し、下階の軒樋から下階の縦樋に流すというようにして排水していた。
【０００３】
ところで、金属屋根材上に這わせる這樋を取付けるに当たっては、這い樋支持金具が用いられていた。
【０００４】
金属屋根材１は図５に示すような形状をしており、金属屋根材１の前端部は、図５（ａ）（ｂ）に示すように、下方に向けて垂下した前縦片１５ａと前縦片１５ａの下端より前方に向けて突出した前横片１５ｂとで構成され、金属屋根材１の後端部は、上方に向けて突設した後縦片１６ａと後縦片１６ａの上端より後方向に向けて突出した後横片１６ｂとで構成される。また、横方向においては、図５（ａ）（ｃ）に示すように、山部１ａと谷部１ｂとが連続する波形状をしたものとなっている。このような構成の金属屋根材１を屋根下地９上に多数葺いて屋根Ａが構成される。そして、このようにして形成した屋根Ａ上には這い樋１０が配置されるが、この這い樋１０は金属屋根材１に対して図１１に示すような這い樋支持金具８’により取付けられる。
【０００５】
這い樋支持金具８’は図１１に示すように支持金具本体４’に這い樋支持部５を設けて構成してある。支持金具本体４’は弾性を有する金属板を折り曲げて本体部Ｈを形成してあり、本体部Ｈの下前端部から両側方及び後方に開口した横向きＵ字状をした引っ掛け部６を前方に突設している。引っ掛け部６の上横片６ａには孔が穿孔してあってこの上横片６ａの上面部には孔に連通してナット２５ａが溶接により固着してあり、ナット２５ａにねじ具２５ｂが螺合してある。また本体部Ｈには這い樋支持部５の下端部がかしめ具により回動自在に取付けてある。
【０００６】
しかして、金属屋根材１上に配置する這い樋１０を金属屋根材１に上記這い樋支持金具８’により支持するには、図１２に示すように、まず、金属屋根材１の谷部１ｂの前端部分に這い樋支持金具８’の横向きＵ状をした引っ掛け部６を引っ掛け、ねじ具２５ｂを螺進させてねじ具２５ｂの先端部で金属屋根材１の前端部上面を押圧することで這い樋支持金具８’を金属屋根材１に本固定する。這い樋支持金具８’を取付けた後、這い樋支持部５の回動側半体１３を回動して開き、這い樋１０を基部側半体１２に嵌め込み、その後に回動側半体１３を閉じて這い樋支持部５により這い樋１０を支持するものである。
【０００７】
しかしながら、このような這い樋支持金具８’は、図１０に示すように、金属屋根材１の谷部１ｂに沿って這い樋１０を這わせるもので、図９に示すように這い樋１０を山部１ａと交差するように這わせる場合には、這い樋支持金具８’の金属屋根材１に取付けられる部分から這い樋支持部５までの長さが短くて図１３に示すように這い樋１０が金属屋根材１の山部１ａを乗り越えられず、この場合には使用することができないものであった。（なお図１３においては、便宜上這い樋１０の方向を９０度回転させたものを示してある。）
【０００８】
【発明が解決しようとする課題】
本発明は上記の点に鑑みてなされたものであり、その目的とするところは、這い樋を金属屋根材の谷部に配設する場合でも、這い樋を金属屋根材の山部と交差するように配設する場合でも同一部材で対応することができる這い樋支持金具を提供することを課題とするものである。
【０００９】
【課題を解決するための手段】
上記課題を解決するために本発明に係る這い樋支持金具は、金属屋根材１に取付ける支持金具本体４と這い樋１０が取着される這い樋支持部５と前記支持金具本体４と這い樋支持部５とを連結する連結部７とからなる這い樋支持金具８であって、ボルトで構成される連結部７の頭部７１を這い樋支持部５の下端部に取付け、前記連結部７の径より小径の挿入孔４１及び該挿入孔４１より放射状に広がる複数条のスリット４２を形成して該スリット４２間を変形部４３とした取付部を支持金具本体４に設け、前記挿入孔４１に連結部７の下端部を挿入して変形部４３の端縁を連結部７のボルトの本体軸部７０のねじ溝に螺合させて変形部４３の変形による弾性力にて連結部７を支持金具本体４に取付けて成ることを特徴とするものである。このような構成とすることで、這い樋１０を金属屋根材１の谷部１ｂに配設する場合でも、這い樋１０を金属屋根材１の山部１ａと交差するように配設する場合でも、同一の這い樋支持金具８で対応することが可能となる。
【００１０】
また、支持金具本体４と這い樋支持部５との間に圧縮挿入するコイルバネ４４を連結部７の外周に配置することが好ましい。このような構成とすることで、這い樋支持部５に取付いた連結部７と支持金具本体４とに互いに離れる方向に力が働くため、連結部７と取付部の変形部４３との螺合状態がずれ難くなるものである。
【００１１】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態に基づいて説明する。
【００１２】
金属屋根材１は図５に示すような形状をしている。即ち、前後方向においては、図５（ａ），（ｂ）に示すように、金属屋根材１の前端部には下方に向けて垂下した前縦片１５ａと前縦片１５ａの下端より前方に向けて突出した前横片１５ｂとで構成される断面略Ｌ状をした前Ｌ状部１５が設けてあり、金属屋根材１の後端部には上方に向けて突設した後縦片１６ａと後縦片１６ａの上端より後方向に向けて突出した後横片１６ｂとで構成される断面逆Ｌ状をした後逆Ｌ状部１６が設けてある。また、横方向においては、図５（ａ），（ｂ）に示すように、山部１ａと谷部１ｂとが連続する波形状をしたものとなっている。
【００１３】
上記のような構成の金属屋根材１を屋根下地９上に多数葺いて屋根Ａを構成するのであるが、本発明においては図６に示すように、金属屋根材１は前端部を後述する吊り子金具２に引っ掛けると共に後端部を釘のような固着具１４により固着することで屋根下地９に取付けるようになっている。
【００１４】
すなわち、屋根下地９上には前後方向（軒と直交する方向）に一定間隔で横桟１７を載置して固着具により固着してある。ここで、前後における横桟１７間の間隔は金属屋根材１の前縦片１５ａと後縦片１６ａとの間の距離と略等しい間隔となっており、金属屋根材１を前後の横桟１７間に配置して、該金属屋根材１の前端部の断面Ｌ状をした前Ｌ状部１５の前横片１５ｂを下段の金属屋根材１の後端部とともに後述のようにして取付けた吊り子金具２の差し込み部３に図６のように差し込み且つ前縦片１５ａを前側の横桟１７の前面に近接対向させると共に、該金属屋根材１の後端部の断面逆Ｌ状をした後逆Ｌ状部１６の後縦片１６ａを後側の横桟１７の前面に近接対向させ且つ後横片１６ｂを後側の横桟１７の上面に載設して後述のようにして吊り子金具２と共に後横片１６ｂを固着具１４により横桟１７に固着する。
【００１５】
吊り子金具２は図７に示すようなもので、縦片部１８の上端から後方に向けて上横片部１９を突設し、縦片部１８の下端から前方に向けて下横片部２０を突設し、下横片部２０の先端部を斜め上後方に向けて折曲して差し込み部３を設けて構成してある。この吊り子金具２を金属屋根材１の後横片１６ｂと共に固着具１４により固着するには以下のようにして行うものである。つまり、図６に示すように、吊り子金具２の縦片部１８を金属屋根材１の後縦片１６ａの前面に近接対向させ、下横片部２０を金属屋根材１の上面に当接し、上横片部１９を後横片１６ｂ上面に当接し、この状態で上横片部１９から釘のような固着具１４を打ち込んで後横片１６ｂと共に上横片部１９を屋根下地９に固着した横桟１７に固着する。これにより金属屋根材１の後端部が屋根下地９に固着されることになる。
【００１６】
このようにして多数の金属屋根材１を次々と葺いて多層階の建物において下階及び上階の屋根Ａを形成するものである。上記屋根Ａは新築の場合に形成する屋根であってもよく、あるいは既設の古い屋根を屋根下地９としてこの上に新しく上記のようにして横桟１７を固着して新しい金属屋根材１を葺くことで形成する改装屋根であってもよい。
【００１７】
上記のようにして形成した多層階の建物の下階の屋根Ａ上には這い樋１０が配置されるが、この這い樋１０は下階の屋根Ａの金属屋根材１に対して図１に示すような這い樋支持金具８により取付けられる。
【００１８】
這い樋支持金具８は図１に示すように支持金具本体４と、這い樋１０が取着される這い樋支持部５と、支持金具本体４と這い樋支持部５とを連結する連結部７とで構成してある。
【００１９】
這い樋支持部５は略半円状又は略コ字状をした基部側半体１２と、略半円状又は略コ字状をした回動側半体１３とで構成してある。基部側半体１２の中央部には、後述する連結部７が取付けられる挿通孔Ｈ_２が連結部７とほぼ同径に穿設してある。回動側半体１３の一端部と基部側半体１２の一端部とは軸支部分２７で回動自在に軸支してあり、また、回動側半体１３の他端の係合部１３ａが基部側半体１２の被係合部１２ａに係合自在となっている。
【００２０】
連結部７は、上下方向を長手方向とするボルトからなるもので、該ボルトの本体軸部７０の径はφ５に形成してある。連結部７は、下端部を這い樋支持部５の基部側半体１２の挿通孔Ｈ_２に上方より挿通し、連結部７の上端部の頭部７１を基部側半体１２に固定してある。そして、連結部７の下端部は、支持金具本体４の取付け用横片２３に設けた取付部に取付けるものであり、以下に説明する。
【００２１】
支持金具本体４は弾性を有する金属板を折り曲げて形成してあり、取付け用横片２３の前端部から垂下片２４を垂下し、垂下片２４の下端から後方に上横片６ａを連出し、上横片６ａの後端から上横片６ａの下面側に沿って下横片６ｂを前方に向けて折り返してあり、上横片６ａと下横片６ｂとで両側方及び前方に開口した横向きＵ字状をした引っ掛け部６を構成している。上横片６ａには孔が穿孔してあってこの上横片６ａの上面部には孔に連通してナット２５ａが溶接により固着してあり、ナット２５ａにねじ具２５ｂが螺合してある。また、取付け用横片２３は部分的に下方に向けて円弧状に凸曲成してあってこの凸曲成した部分が、屋根材弾接部１１となっている。取付け用横片２３の屋根材弾接部１１間の部分には、連結部７が取付けられる取付部が設けられる。
【００２２】
取付部は、挿入孔４１と、挿入孔４１より放射状に広がる複数のスリット４２と、スリット４２間に形成される変形部４３とからなるもので、本実施形態では板状をした取付部を支持金具本体４の取付け用横片２３のφ５．１の下孔Ｈ_１を穿設した部分に、取付けるものである。なお、このような取付部は、別部材を支持金具本体４に取付けて設けなくとも支持金具本体４に直接形成してもよいものである。
【００２３】
取付部の挿入孔４１は、径が連結部７より小径（即ち直径５．１ｍｍ未満）の孔で、この挿入孔４１の周囲より放射状に複数条のスリット４２（本実施形態では８条）が穿設してあり、各スリット４２の間の部分を変形部４３としてある。このような取付部は、挿入孔４１と上記挿通孔Ｈ_１が同心となるように取付け用横片２３に取付けられる。
【００２４】
このような取付部への連結部７の取付けを説明する。ボルトである連結部７の下端部を取付部の挿入孔４１に上方より挿入するのであるが、このとき、挿入孔４１は連結部７のボルトの本体軸部７０の径より小径であるため、挿入孔４１の縁に形成されている変形部４３を変形させながら挿入孔４１に挿入される。変形部４３は隣接する変形部４３とスリット４２にて分離されているため、それぞれ独立に下方へ変形される。そして、変形部４３の端縁が連結部７のボルトの本体軸部７０のねじ溝に螺合し、変形部４３の変形による弾性力にて本体軸部７０が固定される。
【００２５】
そして、このように取付部に取付けた連結部７の高さ調整は、連結部７を軸方向廻りに回転させて変形部４３の端縁への螺合位置を変えることで上下動することができる。
【００２６】
また、このような連結部７の外周には、支持金具本体４と這い樋支持部５との間に圧縮挿入されるコイルバネ４４が設けられる。これにより、這い樋支持部５に取付いた連結部７と支持金具本体４とに互いに離れる方向に力が働くため、連結部７の本体軸部７０と取付部の変形部４３との螺合状態がずれ難くなるものである。
【００２７】
しかして、下階の屋根Ａの金属屋根材１上に配置する這い樋１０を金属屋根材１に上記這い樋支持金具８により支持するには、まず、任意の金属屋根材１の谷部１ｂの前端の吊り子金具２を差し込み係止している部位以外の前端部分に這い樋支持金具８の横向きＵ状をした引っ掛け部６を引っ掛け、これにより這い樋支持金具８が金属屋根材１の前端部分にがたつかないように仮取付けが行われる。
【００２８】
次に、ねじ具２５ｂを螺進させてねじ具２５ｂの先端部で金属屋根材１の前端部上面を押圧することで這い樋支持金具８を金属屋根材１に本固定する（図２参照）。この場合、上記のように這い樋支持金具８を金属屋根材１の前端部にがたつかないように仮取付けした状態でねじ具２５ｂの締め付けによる本固定作業ができるので、屋根上という高所における作業に当たり、ねじ具２５ｂによる本固定作業が簡単且つ正確に行えることになる。また、本固定した状態でもねじ具２５ｂによる固定と支持金具本体４の弾性を利用して金属屋根材１の前端部への取付けとの協同でより確実に取付けられることになる。このようにして這い樋支持金具８を金属屋根材１の前端部に引っ掛けると共にねじ具２５ｂの先端により押圧して取付けたので、金属屋根材１の前端部に釘孔などがあかず、したがって、這い樋支持金具８を金属屋根材１の前端部に取付けても、取付け部分からの雨水の浸入のおそれがないものである。
【００２９】
金属屋根材１に這い樋支持金具８を取付けた後、這い樋支持部５の回動側半体１３を回動して開き、這い樋１０を基部側半体１２に嵌め込み、その後に回動側半体１３を閉じて係合部１３ａを被係合部１２ａに係合して這い樋支持部５により這い樋１０を支持するものである。ここで、屋根Ａ上を這わせる這い樋１０の向きが異なっても金属屋根材１の前端に取付けた支持金具本体４に対して這い樋支持部５を回動させることで対応できるものである。
【００３０】
上述したように這い樋支持金具８を取付けるのであるが、図１０に示すように這い樋１０ａを金属屋根材１の谷部１ｂに配設する場合には、図１（ａ）に示すように這い樋支持部５及び連結部７を下方に引き下げた状態とし、図９に示すように這い樋１０ｂを金属屋根材１の山部１ａと交差するように配設する場合には、図１（ｂ）に示すように這い樋支持部５及び連結部７を上方に引き上げた状態とし、這い樋１０が金属屋根材１の山部１ａの上を該山部１ａと交差するように這わせることができる（図３参照）。なお、図中のＮは軒樋を、Ｓは集水器を示す。
【００３１】
以上のような構成によれば、連結部７の上端部を這い樋支持部５の下端部に固定すると共に、連結部７を支持金具本体４に上下動自在に取付けたので、図１０に示すように這い樋１０ａを金属屋根材１の谷部１ｂに配設する場合でも、図９に示すように這い樋１０ｂを金属屋根材１の山部１ａと交差するように配設する場合でも、簡単な構成の同一の這い樋支持金具８で、這い樋支持部５が取付いた連結部７を上げ下げすることで対応することが可能となる。
【００３２】
【発明の効果】
上記のように本発明の請求項１記載の発明にあっては、金属屋根材に取付ける支持金具本体と這い樋が取着される這い樋支持部と前記支持金具本体と這い樋支持部とを連結する連結部とからなる這い樋支持金具であって、ボルトで構成される連結部の頭部を這い樋支持部の下端部に取付け、前記連結部の径より小径の挿入孔及び該挿入孔より放射状に広がる複数条のスリットを形成して該スリット間を変形部とした取付部を支持金具本体に設け、前記取付部の挿入孔に連結部の下端部を挿入して変形部の端縁を連結部のボルトの本体軸部のねじ溝に螺合させて変形部の変形による弾性力にて連結部を支持金具本体に取付けたので、這い樋を金属屋根材の谷部に配設する場合でも、這い樋を金属屋根材の山部と交差するように配設する場合でも、同一の這い樋支持金具で対応することが可能となる。
【００３３】
また、請求項２記載の発明にあっては、上記請求項１記載の発明の効果に加えて、支持金具本体と這い樋支持部との間に圧縮挿入するコイルバネを連結部の外周に配置したので、這い樋支持部に取付いた連結部と支持金具本体とに互いに離れる方向に力が働くため、連結部と取付部の変形部との螺合状態がずれ難くなるものである。

[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.
[0012]
The metal roofing material 1 has a shape as shown in FIG. That is, in the front-rear direction, as shown in FIGS. 5A and 5B, the front end of the metal roofing material 1 has a front vertical piece 15 a that hangs downward and forward of a lower end of the front vertical piece 15 a. A front L-shaped portion 15 having a substantially L-shaped cross section and provided with a front horizontal piece 15b protruding toward the front is provided.
