Description

【０００１】
【発明の属する技術分野】
本発明は、その前面板に略前方、上方に屈曲する屈曲部を有する軒樋に関するものである。
【０００２】
【従来の技術】
従来から、建築物の屋根と一体感があって外観の美しい、図５に示す如く、略前方、上方に屈曲する屈曲部３３を有する前面板３と底板２と後面板４とから成る軒樋Ａが提案されている。すなわち、この軒樋Ａは、例えば鋼板のような金属板の両面に合成樹脂材料を被覆して形成されて、屋根面と連続するよう前面板３が上部へいくにつれて後方に傾斜しており、また、前耳３４が、その上面開口の巾寸法が内部の巾寸法より小さくなるように前面板上部３２の上端から斜め下方に向けて長手方向にわたって設けられている。
【０００３】
この場合、軒樋Ａを長手方向に接続するときには、対となる軒樋Ａの端部同士を突き合わせ、図６（ａ）に示すような、その軒樋Ａの内面に略当接するよう例えば当接片Ｃを有する合成樹脂材料製の継手の内押さえ部材Ｂを上面開口から装着し、軒樋Ａの内面と内押さえ部材Ｂの外面との間に接着剤を介装するとともに、図６（ｂ）に示すように、軒樋Ａの外面に略当接するとともに、軒樋Ａの前耳３４及び後耳４１に係合する前耳係合部Ｅ及び後耳係合部Ｆを有する外継手Ｄを、上記後面板４上端の後耳４１及び前面板上部３２上端の前耳３４を把持するようにして接着して接続していた。
【０００４】
したがって、上記の軒樋Ａは、内押さえ部材Ｂ及び外継手Ｄにて図７に示すように接続されて、前方に傾斜した前面板３にて建築物と一体感をもたせることが出来、また、屈曲部３３の下端にてその前面板３を流下する水滴の水切りを行うことが出来て、軒樋Ａを下側から見た前面板下部３１が汚れにくくなって使用時においても美観を維持することができる。
【０００５】
【発明が解決しようとする課題】
しかしながら、上記従来の技術においては、軒樋の前面板の屈曲部形状が複雑な場合、継手の内押さえ部材に軒樋の内面に略当接するよう、例えば上記当接片Ｃのような舌片を設けたり、あるいは、内押さえ部材の外形形状をその軒樋の内部形状に合致させる必要があり、成型用の金型製作上手間がかかるという問題があった。また、内押さえ部材の外形形状をその軒樋の内部形状に合致させても、軒樋を製作する場合の成型収縮量のバラツキ等によって、その軒樋の内部形状が内押さえ部材の外形に沿わないことがあった。その結果、軒樋内側と内押さえ部材の外面との間に空間が生じ、上記の接着剤が十分行きわたらない場合に軒樋同士の接続部分の止水性が低下して、その接続部分から雨水が漏れるという問題があった。
【０００６】
本発明は、上記事由に鑑みてなしたもので、その目的とするところは、外観の形状を維持して互いの接続部分の止水性を向上できる軒樋を提供することにある。
【０００７】
【課題を解決するための手段】
上記目的を達成するために、請求項１記載の軒樋は、略前方、上方に屈曲する屈曲部を有する前面板と底板と後面板とから成る軒樋において、前面板は底板前端から前方へ行くように傾斜し屈曲部下方の前面板下部が略階段状に立ち上ると共に屈曲部上方の前面板上部が後方に傾斜するように途中で屈曲し、軒樋の長手方向に亘って前面板変形防止用の平板状の連結片を前面板上部と階段状の前面板下部の内面側角部にて連結すると共に、該連結片の後面と前面板下部の階段部分後側面とを略同一平面になるよう形成し、沿設させて成る。
【０００８】
したがって、この場合、略前方、上方に屈曲する屈曲部を有する前面板と底板と後面板とから成る軒樋において、前面板は底板前端から前方へ行くように傾斜し屈曲部下方の前面板下部が略階段状に立ち上ると共に屈曲部上方の前面板上部が後方に傾斜するように途中で屈曲し、軒樋の長手方向に亘って前面板変形防止用の平板状の連結片を前面板上部と階段状の前面板下部の内面側角部にて連結すると共に、該連結片の後面と前面板下部の階段部分後側面とを略同一平面になるよう形成し、沿設させて連結される。
【０００９】
また、請求項２記載の軒樋は、請求項１記載の連結片を、合成樹脂材料にて前面板及び底板内面に一体形成している。
【００１０】
したがって、この場合、合成樹脂材料製の連結片が、前面板及び底板内面に一体形成される。
【００１１】
【発明の実施の形態】
図１乃至図４は、本発明の請求項１、２に対応する一実施の形態を示し、図１は、本発明の一実施の形態の軒樋を示す概略構成図である。図２は、同軒樋の接続状態を示す側面断面図である。図３は、同軒樋の他の実施例の説明図である。図４は、同軒樋のさらに他の実施例を示した説明図である。
【００１２】
この実施の形態の軒樋１は、略前方、上方に屈曲する屈曲部を有する前面板と底板と後面板とから成る軒樋１において、前面板３は底板２端から前方へ行くように傾斜し屈曲部３３下方の前面板下部３１が略階段状に立ち上ると共に屈曲部３３上方の前面板上部３２が後方に傾斜するように途中で屈曲し、軒樋１の長手方向に亘って前面板変形防止用の平板状の連結片３５を前面板上部３２と階段状の前面板下部３１の内面側角部にて連結すると共に、該連結片３５の後面と前面板下部３１の階段部分後側面とを略同一平面になるよう形成し、沿設させて連結して成る。
【００１３】
又、該実施の形態の軒樋においては、連結片３５を、合成樹脂材料にて前面板３及び底板２内面に一体形成してもいる。
【００１４】
詳しくは、軒樋１は、例えば図１に示すような、上方開口を有する断面大略コ字状であって、鋼板のような金属板の両面に合成樹脂材料を被覆して形成され、前面板３が、底板２前端から前方へいくように傾斜してその前面板下部３１が略階段状に立ち上がり、前面板上部３２が後方に傾斜するように途中で屈曲しており、また、この前面板上部３２上端には前耳３４が斜め後方に垂下し形成されている。また、後面板４は、底板２後端から斜め前方、上方へ向けて立ち上がり、この後面板４上端には、後耳４１が後面板４後方へ向け突出して形成されている。
【００１５】
前面板下部３１には、この場合、意匠を兼ねた、この前面板３を流下する雨水の水切りを行うための、略前方、上方に階段状に屈曲する屈曲部３３が設けられ、また、この屈曲部３３の角部には、水切りを確実に行うための垂下片３６が設けられている。
【００１６】
この場合、屈曲部３３の後方には、平板状の連結片を前面板上部３２と階段状の前面板下部３１の内面側角部にて連結すると共に、該連結片３５の後面と前面板下部３１の階段部分後側面とを略同一平面になるよう形成し、軒樋１の長手方向に亘って沿設されている。この連結片３５は、合成樹脂材料にて形成され、軒樋１の押し出し成型時に前面板３及び底板２の上記被覆材とともにその内面に一体化されている。
【００１７】
上記構成による軒樋１は、例えば図２に示すような内押さえ部材５と外継手６とを使用して直線状に接続することができる。この場合、内押さえ部材５と外継手６とは、従来の技術の項にて示したものと同じく、所定巾寸法を有して合成樹脂材料にて形成されている。
【００１８】
すなわち、内押さえ部材５は、略前方、上方に屈曲する屈曲部３３を有する前面板３と底板２と後面板４とから成る軒樋１内面側の、前面板３の屈曲部３３上方の前面板上部３２と前面板下部３１とが、軒樋１の長手方向に亘って前面板変形防止用の平板状の連結片３５を前面板上部３２と階段状の前面板下部３１の内面側角部にて連結すると共に、該連結片３５の後面と前面板下部３１の階段部分後側面とを略同一平面になるよう形成し、沿設させているので、軒樋１の底板２内面に略当接する底面板５１の前端から、略板状の前面板５２が、軒樋１の前面板下部３１の基端及び連結片３５内面側に当接するよう軒樋１の上部へいくにしたがって前方へ傾斜して形成されており、また、底面板５１の後端から、軒樋１の内部形状に略合致した外形形状を有するように後面板５３が立設されている。
【００１９】
なお、この場合、外継手６は、従来の技術にて説明したものと同一で、軒樋１の底板２外面に略当接する底面板６１の前端から、軒樋１の前面板下部３１及び前面板上部３２に当接するように略前方、上方に屈曲して立ち上がった前面板６２が、その上部へいくにしたがって前方へ傾斜して形成されており、また、底面板６１の後端から、軒樋１の外面形状に略合致した外形形状を有するように後面板６３が立設され、また、前面板６２及び後面板６３の上端には、それぞれ軒樋１の前耳３４及び後耳４１に係合する前耳係合部６４及び後耳係合部６５が設けられている。
【００２０】
したがって、以上説明した軒樋１によると、略前方、上方に屈曲する屈曲部を有する前面板と底板と後面板とから成る軒樋において、前面板３は底板前端から前方へ行くように傾斜し屈曲部下方の前面板下部３１が略階段状に立ち上ると共に屈曲部上方の前面板上部３２が後方に傾斜するように途中で屈曲し、軒樋１の長手方向に亘って前面板変形防止用の平板状の連結片３５を前面板上部３２と階段状の前面板下部３１の内面側角部にて連結すると共に、該連結片３５の後面と前面板下部３１の階段部分後側面とを略同一平面になるよう形成し、沿設されるので、簡単な外形形状の内押さえ部材５を用いて軒樋１を長手方向に接続することができ、以て、屈曲部３３をもった外観の形状を維持して互いの接続部分の止水性を向上させることができる。
【００２１】
また、合成樹脂材料製の連結片３５が、前面板３及び底板２内面に一体形成されるので、容易に屈曲部３３上方の前面板上部３２と前面板下部３１とを連結でき、以て、軒樋の製作コストの上昇を抑えて連結片３５を形成できる。
【００２２】
なお、本発明の軒樋の参考例として、例えば図３に示すように、（ａ）の、従来、僅かに斜め下方へ向け前方に屈曲させた後、上方に屈曲する屈曲部３７を有する前面板３と底板２と後面板４とから成る軒樋７を、（ｂ）に示す如く、平板状の連結片３５を前面板３に沿設させ、前面板３の軒樋１内面側の、屈曲部３７上方の前面板上部３２の屈曲部分の下部と前面板下部３１の屈曲部３７に至る基端部とを、軒樋７の長手方向に亘って連結したものがある。
【００２３】
また、他の実施例としては、図４に示すように、（ａ）の、従来、僅かに斜め下方へ向け前方に屈曲させた後、上方に屈曲する屈曲部３８、３８を階段状に有する前面板３と底板２と後面板４とから成る軒樋８を、（ｂ）に示す如く、平板状の連結片３５を沿設させ、軒樋１の底板２内面側と、屈曲部３８、３８上方の前面板上部３２とを連結したもの、なお参考例として、（ｃ）に示す如く、前面板３の軒樋１内面側の、屈曲部３８、３８上方の前面板上部３２の屈曲部分と前面板下部３１の屈曲部３８に至る基端部とを、軒樋８の長手方向に亘って連結したものがある。
【００２４】
【発明の効果】
上述の如く、本発明の請求項１記載の軒樋は、略前方、上方に屈曲する屈曲部を有する前面板と底板と後面板とから成る軒樋において、前面板は底板前端から前方へ行くように傾斜し屈曲部下方の前面板下部が略階段状に立ち上ると共に屈曲部上方の前面板上部が後方に傾斜するように途中で屈曲し、軒樋の長手方向に亘って前面板変形防止用の平板状の連結片を前面板上部と階段状の前面板下部の内面側角部にて連結すると共に、該連結片の後面と前面板下部の階段部分後側面とを略同一平面になるよう形成し、沿設されるので、簡単な外形形状の内押さえ部材を用いて軒樋を長手方向に接続することができ、以て、屈曲部をもった外観の形状を維持して互いの接続部分の止水性を向上させることができる。
【００２５】
また、請求項２記載の軒樋は、請求項１記載のものの効果に加え、合成樹脂材料製の連結片が、前面板及び底板内面に一体形成されるので、容易に屈曲部上方の前面板上部と前面板下部または底板とを連結でき、以て、軒樋の製作コストの上昇を抑えて連結片を形成できる。

A has been proposed. That is, the eaves gutter A is formed by coating both surfaces of a metal plate such as a steel plate with a synthetic resin material, and is inclined rearward as the front plate 3 goes upward so as to be continuous with the roof surface. Further, the front ear 34 is provided obliquely downward from the upper end of the front plate upper part 32 in the longitudinal direction so that the width dimension of the upper surface opening is smaller than the internal width dimension.
[0003]
In this case, when connecting the eaves gutter A in the longitudinal direction, the ends of the pair of eaves gutters A are abutted with each other and, as shown in FIG. An inner holding member B of a joint made of a synthetic resin material having a contact piece C is attached from an upper surface opening, an adhesive is interposed between the inner surface of the eaves gutter A and the outer surface of the inner holding member B, and FIG. As shown in b), an outer joint having a front ear engaging portion E and a rear ear engaging portion F that substantially abuts the outer surface of the eaves gutter A and engages with the front ear 34 and the rear ear 41 of the eaves gutter A. D was adhered and connected so as to grip the rear ear 41 at the upper end of the rear plate 4 and the front ear 34 at the upper end of the upper portion 32 of the front plate.

[0005]
[Problems to be solved by the invention]
However, in the above-mentioned conventional technique, when the shape of the bent portion of the front plate of the eaves gutter is complicated, the tongue piece such as the abutting piece C, for example, abuts the inner holding member of the joint on the inner surface of the eaves gutter. Or it is necessary to match the outer shape of the inner holding member with the inner shape of the eaves gutter, and there is a problem that it takes time to manufacture a mold for molding. Even when the outer shape of the inner gutter matches the inner shape of the eaves gutter, the inner shape of the eaves gutter follows the outer shape of the inner gutter due to variations in molding shrinkage when manufacturing the eaves gutter. There was nothing. As a result, a space is created between the inside of the eaves gutter and the outer surface of the inner holding member, and when the above-mentioned adhesive is not sufficiently transmitted, the water stopping performance of the connection between the eaves gutter is reduced, and rainwater flows from the connection part. Had the problem of leaking.
