Description

【０００１】
【発明の属する技術分野】
本発明は、屋根面上に積もった雪が軒先から落下しないように雪止めする、雪止め構造に関するものである。
【０００２】
【従来の技術】
従来より、降雪の多い地方では、屋根上からの落雪を防止するため、屋根面に雪止め具６５を取り付けるようにしている。例えば、特開平６−１５８８０２に記載の雪止め具６５は、図１１、図１２に示すように、帯状をした取付本体部６７と、前記取付本体部６７の軒先側の端部に上方に突出するように設けられた雪止め部６６と、取付本体部６７の棟側端部に下向きに折曲された引掛部６８とを有している。この引掛部６８を、屋根材６０が上下相互に重ね合わされる隙間へ差し込んで、下側となる屋根材６０の棟側端部においてビス６９で固定し、各雪止め部６６を介して、雪止め部材６４を掛け渡していた。
【０００３】
【発明が解決しようとする課題】
しかしながら、従来の雪止め具６５においては、既設の屋根面に設置する場合において、引掛部６８を屋根材６０が上下に重ね合わされる隙間へ差し込むために、屋根材６０を取り外したり、持ち上げたりする必要があり、作業が煩雑になるといった欠点があった。
また、引掛部６８を直接屋根材６０や野地板６１にビス止めするために、ビス６９のねじ込み部分より、雨水が屋根材６０に浸入し、屋根材６０が腐食を起こす問題があった。
【０００４】
そこで、本発明は、上記問題点に鑑み、防水効果が高く、屋根面への取付が簡単に行える雪止め構造を提供するようにしたものである。
【０００５】
【課題を解決するための手段】

なお、前記水切板３に、前記ボルト等の締結具１３が貫通する締結孔２２ｂが設けられ、該締結孔２２ｂの開口縁部に、前記水切板３上を流れる水が、該締結孔２２ｂに浸入しないように、上方に盛り上がった水堰止部４９が設けられることが好ましい。
【０００８】
また、前記固定部材２が、上壁が前記取付部１０となる取付凸部７を有するとともに、該取付凸部７の棟側に、底壁が前記固定部１１となる固定凹部９を有し、該固定凹部９の棟側の側壁の上端から、棟側に突出する、固定部材翼片１９を有することが好ましい。
また、前記水切板３が、前記固定部材２を上から覆う被覆部１５と、該被覆部１５の軒先側端部から、軒先側に突出する水切板翼片１６とを備え、該被覆部１５は、前記ボルト等の複数の締結具１３により、前記取付部１０と結合され、前記水切板翼片１６の先端は、前記ボルト等の複数の締結具１３の締結により、屋根面に圧接されることが好ましい。
【０００９】
また、前記止め具５が、前記被覆部１５と当接する底壁部２３と、該底壁部２３の端部から上方に突出する側壁部２４からなり、該底壁部２３は、前記ボルト等の締結具１３により、前記被覆部１５に固定されるとともに、前記側壁部２４には、前記雪止め部材１が締結されることが好ましい。
【００１０】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。
図１〜図６は本発明の雪止め構造の実施の一形態を示すものである。
太陽電池パネル３３が軒先まで配置されている屋根面において、屋根面上に積もった雪が軒先から落下することをを防ぐため、屋根面上に横方向（屋根流れ方向に交差する方向）に雪止め部材１が設置されている。すなわち、図２に示すように、屋根瓦としての機能を持つ太陽電池パネル３３が、屋根面上の棟部から屋根流れ方向に軒先部近くまで設置されている。その太陽電池パネル３３の軒先端から屋根面の軒先部までは、通常の屋根材２９が敷設されている。その軒先部には、雪止め部材１を設置する取付桟４が横方向（屋根流れ方向に交差する方向で、雪止め部材１に沿う方向）に敷設されている。この取付桟４の上面には間隔をおいて複数のボルト１３が突出しており、各々のボルト１３に止め具５が固定され、取付桟４上に立設している。さらに、これら複数の止め具５に、屋根上の雪が縦方向（屋根流れ方向）に移動することを制止する雪止め部材１が架け渡され締結されている。
【００１１】
図１、図３に示すように、前述の取付桟４は、屋根面上に固定される横方向（屋根流れ方向に交差する方向で、雪止め部材１に沿う方向）に長い固定部材２と、固定部材２に対して、上から覆うように固定される、横方向（屋根流れ方向に交差する方向で、雪止め部材１に沿う方向）に長い水切板３とから構成されている。
固定部材２は、厚み１〜２ｍｍ程度のステンレス等の一枚の金属板をクランク形状に折り曲げることにより一体形成されている。当該固定部材２は、取付凸部７を有し、この取付凸部７の軒先側の端部は、棟側に直角に折り曲げられている。加えて、取付凸部７の棟側には、固定凹部９が形成されており、固定凹部９の棟側の側壁の上端から、棟側に、固定部材翼片１９が突出している。さらに、取付凸部７の上壁は、水切板３を取り付ける横方向の取付部１０を構成し、固定凹部９の底壁は、屋根面に固定される横方向の固定部１１を構成している。加えて、前記取付部１０には、水切板３との共締めを行うためのボルト１３の貫通する、複数の締結孔２２ａが具備され、前記固定部１１には、屋根面に固定するためのビス１２が貫通する、複数の固定孔２６が具備されている。
【００１２】
水切板３は、厚み０．３〜０．６ｍｍ程度のステンレス等の一枚の金属板をクランク形状に折り曲げることにより一体形成されている。水切板３は、固定部材２を全長に渡って上から覆う被覆部１５を有する。この被覆部１５の軒先側の側壁の下端から、軒先側に水切板翼片１６が突出しており、水切板翼片１６の先端部は、下側に折り返されている。また、被覆部１５の棟側の先端部は、上側に折り返されており、水切板折返片１７を形成している。被覆部１５の上壁には、前記取付部１０の締結孔２２ａと対応する複数の締結孔２２ｂが、間隔をおいて具備されている。この締結孔２２ｂの開口縁部は、図５，６に示すように、上方に盛り上がった形状となっており、水切板３上を流れる雨水が、締結孔２２ｂに浸入しないような働きをする水堰止部４９を形作っている。この水堰止部４９は、エンボス成形により、金属板を上方に盛り上がるようにした部分に、ドリル等で締結孔２２ｂを開けることにより形成される。
【００１３】
止め具５は、厚み１〜２ｍｍ程度、幅５〜１０ｃｍ程度のステンレス等の一枚の金属板を折り曲げることにより一体形成されている。止め具５は、前記被覆部１５と当接する底壁部２３と、底壁部２３の端部より、内角４５度程度をもって折り返される斜壁部と、この斜壁部の上端部から下方に折り曲げられ、前記底壁部２３に直角に交わる側壁部２４からなり、この側壁部２４の下端部はさらに、底壁部２３と平行で、かつ、接するように斜壁部の方へ折り曲げられ、折返部２５を構成している。この折返部２５には、前記被覆部１５との固定に使用されるボルト１３が貫通する締結孔２２ｄが具備されており、前述の底壁部２３には、前記ボルト１３が貫通し、かつ、水堰止部４９が収まる大きさの締結孔２２ｃ（図示せず）が具備されている。また、側壁部２４には、ボルト１４により、雪止め部材１を固定するための締結孔２１が具備されている。なお、前述のように、底壁部２３と側壁部２４が、斜壁部をもって結合される構成のため、止め具５全体の剛性は、斜壁部がない場合に比べ非常に増すことになる。
【００１４】
雪止め部材１は、厚み１〜２ｍｍ程度のステンレス等の一枚の金属板をＬ字形状に折り曲げることにより一体形成される長尺の部材であり、既成のＬ型鋼材を利用することも可能である。
固定部材２は、固定部１１に具備される固定孔２６に、ビス１２が貫通し、屋根材２９や野地板３０にねじ込まれることにより、横方向に屋根面上で固定されている。併せて、固定部１１と屋根面が接触する面に防水シール２７を張り付け、雨水の屋根材２９への浸入を防ぐようにしている。
【００１５】
さらに、取付部１０の具備する締結孔２２ａに、下方より、ボルト１３を貫通させ、金属板やプラスティック板で作られたスペーサー３１を嵌め込み、水切板３に具備される締結孔２２ｂを貫通させている。加えて、止め具５の底壁部２３に具備される締結孔２２ｃ（図示せず）と、止め具５の折返部２５が具備する締結孔２２ｄを貫通させ、共締めすることにより、水切板３と固定部材２が結合され、取付桟４が構成されるとともに、水切板３と止め具５も固定されることになり、水切板３上に止め具５が立設することになる。
【００１６】
さらに、水切板３に立設する止め具５の側壁部２４には、屋根面上の雪の縦方向の移動を制止する雪止め部材１が、横方向に、複数の止め具５に架け渡され、締結されている。
前述の太陽電池パネル３３は屋根瓦としての機能を持ち、図３、図４に示すように、通常の屋根材２９と同様に、野地板３０に直接葺き上げることができる。この太陽電池パネル３３は、パネル基板３６上に太陽電池パネル本体３５が取り付けられ、下地となるベース部材３７に固定される構成となっている。
【００１７】
パネル基板３６は、その軒先側の端部において、取付片４６と折返片４３とを形成しており、ベース部材３７の軒先側の端部には、ベース部材３７を野地板３０に固定する固定ブラケット３９が取り付けられている。
固定ブラケット３９は、帯状の金属板材をコ字形に屈曲成形してなり、野地板３０にビス止めされている。また、固定ブラケット３９の上方の先端部には、前記取付片４６が、ストッパー金具４１を介して、止めネジ４２で固定されている。また、前記取付片４６と共に固定ブラケット３９にネジ止めされるストッパー金具４１は、棟側に突出する爪部を有しており、この爪部に太陽電池パネル本体３５の軒先側の端部を引っ掛けることにより、太陽電池パネル３３が縦方向にずれるのを規制している。
【００１８】
屋根面上で、縦方向に太陽電池パネル３３と本発明の雪止め構造が隣接する場合、両者は以下のように係合されている。すなわち、図３、図４において、固定部材２に水切板３が締結固定されることにより、固定部材翼片１９と水切板折返片１７が圧接し、圧接部４５が構成されている。この圧接部４５が太陽電池パネル３３の軒先側端部の下側に差し込まれており、その上で、断面コ字状に屈曲形成された長尺の接続部材４０が軒先側から差し込まれ、水切板折返片１７とパネル基板３６の具備する折返片４３とに、嵌め込まれることで、前記固定部材２に雨水が浸入しないように、太陽電池パネル３３と本発明の雪止め構造が接続されている。
【００１９】
上記実施の形態によれば、雪止め部材１を太陽電池パネル３３の軒先端側の屋根面上に設置する場合は、固定部材２は、ビス１２を屋根材２９や野地板３０にねじ込むことで、横方向に屋根面上で固定される。併せて、固定部１１と屋根面が接触する面に防水シール２７を張り付け、雨水の屋根材２９への浸入を防ぐようにする。さらに、固定部材２の具備する締結孔２２ａに、下方より、ボルト１３を貫通させ、金属板やプラスティック板で作られたスペーサー３１を嵌め込み、水切板３に具備される締結孔２２ｂを貫通させ、止め具５の底壁部２３に具備される締結孔２２ｃ（図示せず）と、止め具５の折返部２５が具備する締結孔２２ｄを貫通させ、共締めすることで、水切板３と固定部材２を結合し、水切板３と止め具５も固定させる。これにより水切板３上に止め具５を立設させる。さらに、この止め具５の側壁部２４に、雪止め部材１を横方向に架け渡し、雪止め構造を形成する。
【００２０】
以上のように、本発明の雪止め構造は、屋根面上に固定される横方向に長い固定部材２と、固定部材２に対して、上から覆うように固定される横方向に長い水切板３から構成され、その水切板３上に止め具５を立設させ、雪止め部材１を取り付けるようになっている。したがって、従来より、簡便に雪止め部材１を屋根面上に取り付けることができ、作業の省力化が可能となる。また、水切板翼片１６が屋根面に圧接する構造により、屋根面と水切板３の間に雨水が浸入することを防ぐことができ、防水効果をあげることができる。
【００２１】
一方、水切板３は、水堰止部４９を具備しているため、止め具５との締結部において、折返部２５と底壁部２３、もしくは、底壁部２３と水切板３の間を浸入してくる雨水は、水堰止部４９がない場合は、水切板３の具備する締結孔２２ｂを通って、固定部材２側まで浸入し、ついには、ビス１２と屋根材２９の隙間を雨水が入り込むことになり、屋根材２９の腐食の原因となる。しかし、水堰止部４９があるために、雨水は水堰止部４９の周囲を流れ、水切板３の締結孔２２ｂから内部に浸入することはなくなり、防水効果が非常に上がることになる。加えて、水堰止部４９が折返部２５と接触する面にも防水シール２７を塗布することにより、さらなる防水効果を発揮させている。これらにより、屋根材２９に対して防水効果の非常に高い雪止め構造を実現できる。
【００２２】
また、太陽電池パネル３３の軒先端側の屋根面上に、本発明の雪止め構造を設ける場合は、太陽電池パネル３３と本発明の雪止め構造の重なり合う部分に、断面コ字状に屈曲形成された長尺の接続部材４０を軒先側から差し込み、両者を係合させる。詳しくは、固定部材翼片１９と水切板折返片１７が圧接することで形成される圧接部４５を、太陽電池パネル３３の軒先側の端部の下側に差し込み、その上で、接続部材４０を軒先側から差し込み、水切板折返片１７と折返片４３とに嵌め込み、前記固定部材２側に雨水が浸入しないように両者を接続する。
【００２３】
これにより、太陽電池パネル３３が軒先部まで配置されている屋根面においても、雪止め部材１をその軒先部に設置することが可能となる。
なお、本発明は、上記実施の形態に限定されるものではない。
すなわち、図２において、屋根上に取り付けられている太陽電池パネル３３は、それに限定されるものではなく、太陽熱温水器等の屋根上機器であってもかまわない。加えて、太陽電池パネル３３と本発明の雪止め構造の配置関係は、図２に示したものに限定されない。すなわち、一枚の太陽電池パネル３３の軒先部側に本発明の雪止め構造があってもよい。また、複数の太陽電池パネル３３が敷設されることで形成される太陽電池パネル群の軒先部側に本発明の雪止め構造があってもよい。また、太陽電池パネル３３や太陽電池パネル群の軒先部側に本発明の雪止め構造が配置され、その雪止め構造の軒先部側に、さらに太陽電池パネル３３や太陽電池パネル群が敷設してあっても何ら問題はない。
【００２４】
また、図５において、水堰止部４９は、例えば、締結孔２２ｂの穴開け作業時に生じる、金属板のかえりを利用したもので形成されてもよく、水切板３がプラスティック等で成形される場合においては、水堰止部４９が形成されるように、最初から金型を設計しておいてもよい。
また、図７に示すように、固定部１１を直接野地板３０に取り付けるような場合においては、固定部材折返片２０が接する屋根材２９と、固定部１１が接する野地板３０の間には、大きい段差が生じている。従って、この場合、前述の本発明の実施の一形態における固定凹部９より、深さの深い固定凹部９が形成されていることが好ましい。また、固定凹部９の深さが深い場合には、固定部材２を屋根面に安定して固定することが難しくなる。それに対処するためには、図８に示すように、固定部材折返片２０を、軒先側に長く突出させる形状にすることが好ましい。
【００２５】
また、衝撃に弱い屋根材２９などに、取付桟４を敷設する場合においては、屋根材２９の破損防止を考慮し、図９のように固定凹部９と取付凸部７の深さが同じで、かつ、前述の本発明の実施の一形態よりその深さが深くなっている固定部材２を用いることが好ましい。すなわち、この固定部材２の固定部１１と固定部材折返片２０を共に屋根材２９ではなく、野地板３０に固定することで、固定部材２を屋根面上に敷設し、その上から水切板３を嵌め合わせることにより取付桟４を形成する。
【００２６】
また、止め具５も、雪止め部材１を屋根面上の横方向に設置できるものであれば、種々の形状であってもよく、図１０に示すように、前記底壁部２３に直角に交わる側壁部２４の端部が、底壁部２３と平行で、かつ、接するように、斜壁部とは反対の方向へ折り曲げられ、折返部２５を構成するものであってもかまわない。この場合、雪止め部材１を固定する側壁部２４が、前述の本発明の実施の一形態の止め具５より軒先側に位置することになる。従って、雪止め部材１もさらに軒先側に設置されることになり、多くの雪を堰き止める効果が生まれる。
【００２７】
また、雪止め部材１、固定部材２、水切板３、止め具５は、金属板を一体成形することにより形成されるだけでなく、長尺の金属板を適宜切断、溶接固定することにより製作することができる。また、プラスティック材により、一体成形することも可能である。
【００２８】
【発明の効果】
本発明によれば、防水効果が高く、屋根面への取付を簡単に行える雪止め構造を提供することが可能となる。

The stop member 64 was stretched over.
[0003]
[Problems to be solved by the invention]
However, when the conventional snow stopper 65 is installed on an existing roof surface, the roofing material 60 is removed or lifted in order to insert the hooking portion 68 into the gap where the roofing material 60 is superposed vertically. There is a disadvantage that it is necessary and the work becomes complicated.
Further, in order to screw the hooking portion 68 directly to the roofing material 60 or the base plate 61, rainwater entered the roofing material 60 from the screwed portion of the screw 69, and the roofing material 60 was corroded.

[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIGS. 1-6 shows one Embodiment of the snow stop structure of this invention.
In order to prevent the snow on the roof surface from falling from the eaves edge on the roof surface where the solar panel 33 is arranged up to the eaves edge, the snow is stopped in the lateral direction (direction intersecting the roof flow direction) on the roof surface. Member 1 is installed. That is, as shown in FIG. 2, the solar cell panel 33 having a function as a roof tile is installed from the ridge on the roof surface to the vicinity of the eaves in the roof flow direction. A normal roofing material 29 is laid from the eaves tip of the solar cell panel 33 to the eaves tip portion of the roof surface. A mounting bar 4 on which the snow stopper member 1 is installed is laid in the eaves portion in a lateral direction (a direction intersecting the roof flow direction and along the snow stopper member 1). A plurality of bolts 13 protrude from the upper surface of the mounting bar 4 at intervals, and a stopper 5 is fixed to each bolt 13 and stands on the mounting bar 4. Furthermore, a snow stopper member 1 that stops the snow on the roof from moving in the vertical direction (roof flow direction) is bridged and fastened to the plurality of stoppers 5.
[0011]
As shown in FIG. 1 and FIG. 3, the mounting bar 4 described above includes a fixing member 2 that is fixed on the roof surface and that is long in the lateral direction (the direction crossing the roof flow direction and along the snow stop member 1). The draining plate 3 is fixed to the fixing member 2 so as to cover it from above, and is long in the lateral direction (direction intersecting the roof flow direction and along the snow stopper member 1).
The fixing member 2 is integrally formed by bending a single metal plate such as stainless steel having a thickness of about 1 to 2 mm into a crank shape. The fixing member 2 has an attachment projection 7, and an end of the attachment projection 7 on the eaves side is bent at a right angle to the ridge side.
