【発明の詳細な説明】
【０００１】
【発明の属する技術分野】
本発明は家屋などの傾斜屋根に積もった雪の落雪を防止する装置に関するものである。
【０００２】
【従来の技術】
傾斜屋根に降り積もった雪は集積されて次第に大きな雪塊になり、天候が快復すると太陽の熱や傾斜屋内の熱で雪塊の下面が融けて傾斜屋根を滑って軒先から落雪する。このような落雪は、時には軒先の下にある物を壊し、時には通行人に当たるなどの危害を発生させる。このため、一般に傾斜屋根に上面に突起を設けた雪持ち瓦を設置するなどして、落雪が発生するのを防止している。
【０００３】
また、落雪を防止する装置としては、例えば、下記特許文献に記載されている装置などが知られている。
【０００４】
【特許文献１】特開２００１−００３５２６号公報
【特許文献２】特開平８−３１９７０６号公報
【０００５】
【発明が解決しようとする課題】
上記の雪持ち瓦を用いた場合でも、傾斜屋根の表面は、滑り易く依然落雪し易い状態であるから、落雪が発生する可能性がある。また、傾斜屋根の雪持ち瓦を設置した位置より下側では落雪が生じることになる。また、屋根の軒先では、降り積もった雪が徐々に滑って雨樋を包み込んで凍結することがある。そして、このため雨樋に大きな負荷が掛かり、雨樋が壊れてしまうこともある。また、雪が雨樋を包み込んで凍結している場合には、昼間に解けた雪解け水が屋根の軒先部分に溜まり、軒先部分の屋根瓦の隙間から屋内に浸入する「すがもり」と呼ばれる事象が生じ場合もあった。
【０００６】
特許文献１、２に記載されている装置は、落雪や「すがもり」などを防止することできるのであるが、装置が大きく、施工に手間が掛かり、見栄えが悪く、また雪の積もらない季節では、台風などの強風により煽られ易いものであった。
【０００７】
本発明者らは、簡単な構造で効果的に落雪を防止でき、かつ、美観を損なわせない屋根用落雪防止装置を、特願２００１−２３７８７７号において提案している。この屋根用落雪防止装置は、傾斜屋根の上面に沿って網材を配設したものであり、網材の網目や凹凸形状で雪を保持し、落雪を防止するものであった。この屋根用落雪防止装置は、施工が簡単であり、落雪防止効果に優れ、嵩張らないので美観に与える影響が小さく、また、強風が吹いても煽られることがほとんどないものであった。
【０００８】
しかし、屋根瓦が湾曲している日本瓦では網材と屋根との間に空間を確保することができ、優れた融雪効果を備えているのであるが、平板状の洋瓦では網材と屋根との間の空間が狭くなるため、融雪効果が低下するという問題があった。
【０００９】
本発明は、上記の屋根用落雪防止装置を改良し、落雪防止機能、融雪機能を向上させ、また平板状の洋瓦（カラーベスト屋根や鋼板屋根）にも対応できる屋根用落雪防止装置を提供することを目的としている。
【００１０】
【課題を解決するための手段】
本発明に係る屋根用落雪防止装置は、網材の片面に円筒形状の線条体を取り付けた屋根用落雪防止装置であって、傾斜屋根の上面において、傾斜屋根の軒先と略平行になるように、かつ、傾斜屋根の上に転動可能に設置した円筒形状の線条体と、傾斜屋根の上面から円筒形状の線条体の上、軒先にわたって張設した網材とを備えたものである。ここで、円筒形状の線条体には、例えば、鋼線を螺旋状に巻回したものや、網状の線材を円筒形状に組んだものなどを採用することができる。
【００１１】
この屋根用落雪防止装置によれば、円筒形状の線条体を取り付けたことにより、傾斜屋根の上面と網材との間の空間を確保することができ、平板状の洋瓦にも対応することができるようになり、また融雪機能が向上する。また、網材に大量の雪が降り積もった場合には、雪の重みにより線条体が少し転動し、網材の撓みを吸収するとともに、線条体の近傍で網材の傾斜が急になり、これにより落雪防止機能が向上する。
【００１２】
【発明の実施の形態】
以下、本発明の一実施形態に係る屋根用落雪防止装置を図面に基づいて説明する。
【００１３】
この屋根用落雪防止装置１は、図１に示すように、網材２と、網材２の片面に取り付けた螺旋状の鋼線材３とを備えている。
【００１４】
網材２は、所要の長さと幅を備えた略矩形の金網である。本明細書において網材２は図２に示すように傾斜屋根４に設置したときに、傾斜屋根４の傾斜に平行になる方向を「上下方向」とし、傾斜屋根４の軒先に平行になる方向を「幅方向」とする。この網材２は、ワイヤーが互いに上下方向に係合するように構成したひし形金網を採用しており、上下方向に巻き取ることができるようになっている。網材２の上下方向の両側縁には、網目に枠線ワイヤー５、６等の直線材を通し、網材２の型崩れを防止している。
【００１５】
螺旋状の鋼線材３は、本発明における円筒形状の線条体を構成する部材であり、所要の剛性を有する線材を螺旋状に湾曲したものである。鋼線材３は、網材２の上下方向の一端側に、網材２の幅方向に平行になるように取り付けている。鋼線材３は、例えば、鋼線材３の上に網材２を配設し、鋼線材３と網材２が接する箇所に針金７を巻き付けることにより、結合部に自由度を持たせて取り付けている。
【００１６】
この屋根用落雪防止装置１は、図３に示すように、鋼線材３を巻芯として、網材２を鋼線材３に巻き付けることによりコンパクトに収納でき、かつ、この状態で仮止めして搬送することにより搬送が容易になる。
【００１７】
この屋根用落雪防止装置１を傾斜屋根４に取り付けるときは、図２、図４に示すように、例えば、傾斜屋根４の軒先に雨樋８を取り付けている金具９（雨樋受け金具や雨樋支持金具）と、傾斜屋根４に施工した雪持ち瓦１０の雪持ち用の突起１１に、それぞれ専用の繋止金具１２、１３を取り付ける。そして、傾斜屋根４の上面に網材２を鋼線材３に巻き付けた状態で、傾斜屋根４の上に屋根用落雪防止装置１を搬送し、傾斜屋根４の軒先と平行になるように設置する。次に、屋根用落雪防止装置１の仮止めを外して、図２に示すように、網材２の下側の側縁に通した枠線ワイヤー５を、雨樋８に取り付けた繋止金具１２に引っ掛ける。次に、螺旋状の鋼線材３を傾斜屋根４の軒先と略平行になるように傾斜屋根４の上面に設置し、網材２を上下方向上側に延在させ、網材２の上縁を上側に引っ張って、網材２の上側の側縁に通した枠線ワイヤー６を雪持ち瓦１０の突起１１に取り付けた繋止金具１３に引っ掛ける。
【００１８】
このように、屋根用落雪防止装置１は、螺旋状の鋼線材３を傾斜屋根４の軒先と略平行に配設し、網材２を傾斜屋根４の上面から、鋼線材３の上、軒先にわたって張設する。また、雪持ち瓦１０が無い傾斜屋根に取り付ける場合は、網材２の上側の側縁に通した枠線ワイヤー６を引っ掛ける繋止金具を傾斜屋根４の上面の適当な位置に取り付けるとよい。例えば、図５に示すように、傾斜屋根４の瓦１４の隙間に略Ｓ字状に曲げた繋止金具１５を取り付けて網材２の上側の側縁に通した枠線ワイヤー５を引っ掛けると良い。また、網材２の下側の側縁は、図２、図４に示すように、雨樋の下側にある雨樋受け金具に繋止金具を取り付け、網材２で雨樋を包み込んで網材２の下側の側縁に取り付けた枠線ワイヤー５を繋止金具９に引っ掛けても良いし、図５に示すように、瓦の前端縁部に取り付けた繋止金具１６や（図示は省略するが）雨樋の上側にある雨樋支持金具に取り付けた繋止金具に網材２を引っ掛けても良い。
【００１９】
この屋根用落雪防止装置１によれば、図４又は図５に示すように、螺旋状の鋼線材３を取り付けたことにより、傾斜屋根４の上面と網材２との間の空間を確保することができる。網材２の上に降り積もった雪の下は、かまくらのように暖かい空気が滞留し、網材２の上に降り積もった雪を早く解かすように作用する。また、網材２の下に配設した螺旋状の鋼線材３は、雪解け水を堰止めることがないので、雪解け水は、速やかに雨樋８に流れ落ちるようになっている。
【００２０】
また、雪が網材２の上に降り積もると、図６に示すように、雪１７の重さにより網材２が撓む。このとき、網材２の下に配設した螺旋状の鋼線材３が傾斜屋根４の上で少し転動し、又は、螺旋状の鋼線材３が傾斜屋根４の上で少し滑り、網材２の撓みを吸収するとともに、鋼線材３の近傍で網材２の傾斜が急になり、鋼線材３よりも上方に降り積もった雪１７の落雪をより効果的に防止する。
【００２１】
また、図２、図４に示すように、雨樋８を包み込むように網材２を取り付けることにより、雪が雨樋８を覆って凍結することがないので、雨樋８に大きな負荷が掛かるのを防止できる。網材２にテンションを掛けて施工することにより、雨樋８を上側に引き上げようとする力が網材２から雨樋８に作用し、雨樋８が壊れるのを防ぐことができる。
【００２２】
このように、屋根用落雪防止装置によれば、融雪効果と落雪防止効果が共に向上する。また網材２の下に螺旋状の鋼線材３を取り付けたことにより、傾斜屋根４の上面と網材２との間の空間を確保することができるので、湾曲した屋根瓦が用いられ、傾斜屋根に凹凸がある日本瓦屋根だけでなく、平板状の洋瓦、鋼板、カラーベストなどを用いた凹凸の無い傾斜屋根にも、上記のように所要の融雪効果と、落雪防止効果を確保することができる。また、施工については、本発明者らが特願２００１−２３７８７７号において提案している屋根用落雪防止装置と同様に行えるので、施工作業の手間が煩雑でないばかりか、螺旋状の鋼線材３が巻芯となり、コンパクトに収納でき、搬送が容易なものとなるので施工作業がより行い易くなる。また、螺旋状の鋼線材３は、直径が３０ｍｍ〜７０ｍｍ程度のものでも良いので、本発明者らが特願２００１−２３７８７７号において提案している屋根用落雪防止装置と比べても、美観を極端に損なわせない。
【００２３】
以上、本発明の一実施形態に係る屋根用落雪防止装置を説明したが、本発明に係る屋根用落雪防止装置は上記に限定されるものではない。
【００２４】
例えば、網材は、ひし形金網、厚ネット、溶接金網、クリンプ金網、亀甲金網やエキスパンド金網を採用することができる。また、網材や螺旋状の鋼線材はプラスチック製、樹脂製、化学繊維製、ＦＲＰ製、ゴム製等でも良いが、網材の強度及び耐候性を考慮し、亜鉛メッキ塗装を施した鉄線ワイヤーものが好適である。また、円筒形状の線条体として、螺旋状の鋼線材を例示したが、円筒形状の線条体は、これに限らず網状の線材を円筒形状などの種々の線条体を採用することができる。また、美観上、網材や線条体の色を屋根の色に合わせるとよい。
【００２５】
また、円筒形状の線条体としての螺旋状の鋼線材３は、図７に示すように、網材２の下に、２又は複数個取り付けてもよい。
【００２６】
また、屋根用落雪防止装置の取り付け方法、繋止金具は上記に限定されず、また突風で網材が煽られないように網材を所定箇所、傾斜屋根に固定しておくと良い。
【００２７】
【発明の効果】
本発明に係る屋根用落雪防止装置は、網材の片面に円筒形状の線条体を取り付けた屋根用落雪防止装置であって、傾斜屋根の上面において、傾斜屋根の軒先と略平行になるように、かつ、傾斜屋根の上に転動可能に設置した円筒形状の線条体と、傾斜屋根の上面から円筒形状の線条体の上、軒先にわたって張設した網材とを備えたものである。この屋根用落雪防止装置によれば、線条体により、傾斜屋根の上面と網材との間の空間を確保することができるので、平板状の洋瓦にも対応することができるようになり、また融雪機能が向上する。また、線条体が円筒形状であるので、網材に大量の雪が降り積もった場合には、雪の重みにより線条体が少し転動し、網材の撓みを吸収するとともに、線条体の近傍で網材の傾斜が急になり、これにより落雪防止機能が向上する。

DETAILED DESCRIPTION OF THE INVENTION
[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an apparatus for preventing snow falling on a sloped roof such as a house.
[0002]
[Prior art]
The snow that accumulates on the sloping roof gradually accumulates into a large snow mass, and when the weather recovers, the bottom surface of the snow mass melts due to the heat of the sun and the heat inside the sloping indoor, and the snow slides down the sloping roof and falls from the eaves. Such snowfall sometimes destroys objects under the eaves and sometimes causes harm, such as hitting pedestrians. For this reason, snowfall is generally prevented by installing snow-covered tiles having projections on the upper surface of the sloped roof.
[0003]
Further, as a device for preventing snowfall, for example, a device described in the following patent document is known.
[0004]
[Patent Document 1] Japanese Patent Application Laid-Open No. 2001-003526 [Patent Document 2] Japanese Patent Application Laid-Open No. 8-319706 [0005]
[Problems to be solved by the invention]
Even if the above-mentioned snow-clad roof tiles are used, the surface of the sloping roof is slippery and still falls easily, so there is a possibility that snow falls. Also, snow falls below the position where the snow-roof tiles are installed on the sloping roof. Also, at the eaves of the roof, the falling snow may gradually slide and wrap around the gutter and freeze. As a result, a heavy load is applied to the rain gutter, and the gutter may be broken. In addition, when snow wraps around the rain gutter and freezes, the thaw water melted during the day accumulates on the eaves of the roof, and enters the room through the gap between the roof tiles at the eaves, an event called “sugamori”. Sometimes occurred.
[0006]
The devices described in Patent Literatures 1 and 2 can prevent snowfall and “sparing”, but the device is large, it takes time for construction, the appearance is poor, and there is no snow in the season. Then, they were easily blown by strong winds such as typhoons.
[0007]
The present inventors have proposed in Japanese Patent Application No. 2001-237877 a roof snowfall prevention device that can effectively prevent snowfall with a simple structure and does not impair the appearance. In this roof snowfall prevention device, a net material is provided along the upper surface of a sloping roof, and the snow is held by a mesh or uneven shape of the net material to prevent snowfall. This roof snowfall prevention device was simple in construction, excellent in snowfall prevention effect, and not bulky, so it had little effect on aesthetics, and was hardly fanned even by strong winds.
[0008]
However, Japanese tiles with curved roof tiles can secure a space between the net material and the roof and have an excellent snow-melting effect. There is a problem that the snow melting effect is reduced due to the narrow space between the two.
[0009]
The present invention provides a roof snowfall prevention device which improves the above snowfall prevention device for a roof, improves a snowfall prevention function and a snow melting function, and can cope with a flat Western tile (color best roof or steel plate roof). It is intended to be.
[0010]
[Means for Solving the Problems]
A roof snowfall prevention device according to the present invention is a roof snowfall prevention device in which a cylindrical striated body is attached to one surface of a netting material, and has a top surface of a sloped roof that is substantially parallel to an eaves tip of the sloped roof. And a cylindrical striated body that can be rolled on a sloping roof, and a net material stretched from the upper surface of the sloping roof to the cylindrical striated body and over the eaves. is there. Here, as the cylindrical linear body, for example, a spirally wound steel wire, a meshed wire rod formed in a cylindrical shape, or the like can be used.
[0011]
According to this roof snowfall prevention device, the space between the upper surface of the sloping roof and the net can be secured by attaching the cylindrical striated body, and the flat roof tile can be accommodated. And the snow melting function is improved. Also, when a large amount of snow falls on the net, the striated body rolls slightly due to the weight of the snow, absorbing the bending of the net, and the inclination of the net near the striated steep. This improves the snowfall prevention function.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a roof snowfall prevention device according to an embodiment of the present invention will be described with reference to the drawings.
[0013]
As shown in FIG. 1, the roof snow fall prevention device 1 includes a net 2 and a spiral steel wire 3 attached to one side of the net 2.
[0014]
The net material 2 is a substantially rectangular wire net having a required length and width. In this specification, when the net 2 is installed on the sloped roof 4 as shown in FIG. 2, the direction parallel to the slope of the sloped roof 4 is referred to as “vertical direction”, and the direction parallel to the eaves of the sloped roof 4. Is referred to as “width direction”. The mesh material 2 employs a rhombus wire mesh in which wires are vertically engaged with each other, and can be wound up and down. Straight members such as frame wires 5 and 6 are passed through the mesh on both side edges in the vertical direction of the mesh member 2 to prevent the mesh member 2 from being out of shape.
[0015]
The spiral steel wire 3 is a member constituting the cylindrical linear body in the present invention, and is formed by spirally bending a wire having a required rigidity. The steel wire 3 is attached to one end of the net 2 in the vertical direction so as to be parallel to the width of the net 2. The steel wire 3 is attached, for example, by arranging the mesh material 2 on the steel wire material 3 and winding the wire 7 around a place where the steel wire material 3 and the mesh material 2 are in contact with each other, so that the joint has a degree of freedom. I have.
[0016]
As shown in FIG. 3, the roof snowfall prevention device 1 can be compactly stored by winding the net material 2 around the steel wire 3 with the steel wire 3 as the core, and temporarily conveyed in this state. This facilitates transportation.
[0017]
When the roof snowfall prevention device 1 is attached to the sloped roof 4, as shown in FIGS. 2 and 4, for example, a fitting 9 (a gutter receiving fitting or a rain gutter) for attaching a rain gutter 8 to the eaves of the sloped roof 4. Gutter support fittings) and dedicated snow-holding fittings 12, 13 are attached to the snow-holding projections 11 of the snow-covered tile 10 constructed on the inclined roof 4. Then, with the net material 2 wound around the steel wire 3 on the upper surface of the sloping roof 4, the roof snowfall prevention device 1 is transported onto the sloping roof 4 and installed so as to be parallel to the eaves of the sloping roof 4. . Next, the temporary fixing of the snow fall prevention device 1 for the roof is removed, and as shown in FIG. Hook on 12. Next, the spiral steel wire 3 is installed on the upper surface of the inclined roof 4 so as to be substantially parallel to the eaves of the inclined roof 4, and the net 2 is extended upward in the vertical direction. Pulling the wire upward, the frame wire 6 passed through the upper side edge of the net material 2 is hooked on the locking metal 13 attached to the projection 11 of the snow-covered tile 10.
[0018]
As described above, the roof snowfall prevention device 1 arranges the spiral steel wire 3 substantially in parallel with the eaves of the inclined roof 4, and places the net 2 from the upper surface of the inclined roof 4 on the steel wires 3 and the eaves. Stretch over. Further, in the case of mounting on a sloped roof without the snow-covered roof tiles 10, it is preferable to attach a fastener for hooking the frame wire 6 passed through the upper side edge of the net material 2 at an appropriate position on the upper surface of the sloped roof 4. For example, as shown in FIG. 5, when a fastening metal 15 bent in a substantially S shape is attached to the gap between the tiles 14 of the inclined roof 4 and the frame wire 5 passed through the upper side edge of the mesh material 2 is hooked. good. As shown in FIGS. 2 and 4, the lower side edge of the net member 2 is attached to a rain gutter receiving bracket below the rain gutter, and the net gutter 2 wraps the rain gutter. The frame wire 5 attached to the lower side edge of the net material 2 may be hooked on the anchor 9 or, as shown in FIG. 5, an anchor 16 attached to the front edge of the tile (see FIG. 5). Although not shown), the net member 2 may be hooked on a metal fitting attached to a rain gutter supporting metal fitting above the rain gutter.
[0019]
According to the roof snowfall prevention device 1, as shown in FIG. 4 or FIG. 5, the space between the upper surface of the sloping roof 4 and the net 2 is secured by attaching the spiral steel wire material 3. be able to. Under the snow that has fallen on the net 2, warm air like a kama stagnates and acts to quickly melt the snow that has fallen on the net 2. Further, since the spiral steel wire 3 disposed below the net 2 does not block the thaw water, the thaw water quickly flows down to the rain gutter 8.
[0020]
When snow falls on the net 2, the net 2 is bent by the weight of the snow 17, as shown in FIG. At this time, the spiral steel wire rod 3 arranged under the net 2 slightly rolls on the inclined roof 4 or the spiral steel wire 3 slightly slides on the inclined roof 4, In addition to absorbing the bending of the steel wire 3, the inclination of the net material 2 in the vicinity of the steel wire 3 becomes steep, and the snow 17 that has fallen above the steel wire 3 is more effectively prevented from falling.
[0021]
Also, as shown in FIGS. 2 and 4, by attaching the net material 2 so as to wrap the rain gutter 8, since the snow covers the rain gutter 8 and does not freeze, a large load is applied to the rain gutter 8. Can be prevented. By applying tension to the net 2, a force for pulling the rain gutter 8 upward acts on the rain gutter 8 from the net 2, and the rain gutter 8 can be prevented from being broken.
[0022]
As described above, according to the roof snow fall prevention device, both the snow melting effect and the snow fall prevention effect are improved. In addition, by attaching the spiral steel wire 3 under the net 2, a space between the upper surface of the inclined roof 4 and the net 2 can be secured. The required snow melting effect and snow fall prevention effect are ensured not only on Japanese tile roofs with uneven roofs but also on sloped roofs without unevenness using flat Western tiles, steel plates, color vests, etc. be able to. In addition, since the construction can be performed in the same manner as the roof snow fall prevention device proposed by the present inventors in Japanese Patent Application No. 2001-237877, not only is the labor of the construction work not complicated, but also the spiral steel wire rod 3 is used. It becomes a core, can be stored compactly, and can be easily transported, so that the work can be performed more easily. Further, since the spiral steel wire 3 may have a diameter of about 30 mm to 70 mm, the appearance of the spiral steel wire 3 is better than that of the roof snowfall prevention device proposed by the present inventors in Japanese Patent Application No. 2001-237877. Do not impair extremely.
[0023]
Although the roof snowfall prevention device according to one embodiment of the present invention has been described above, the roof snowfall prevention device according to the present invention is not limited to the above.
[0024]
For example, the mesh material may be a diamond wire mesh, a thick net, a welded wire mesh, a crimp wire mesh, a turtle shell wire mesh, or an expanded wire mesh. The net material or spiral steel wire may be made of plastic, resin, chemical fiber, FRP, rubber, etc., but in consideration of the strength and weather resistance of the net material, zinc-coated iron wire Those are preferred. Further, as the cylindrical wire, a spiral steel wire is exemplified, but the cylindrical wire is not limited to this, and various wire such as a net-shaped wire may be employed. it can. Also, it is good to match the color of the net material and the striated body with the color of the roof for aesthetic reasons.
[0025]
As shown in FIG. 7, two or more spiral steel wires 3 as a cylindrical linear body may be attached below the mesh material 2.
[0026]
In addition, the method of attaching the roof snow fall prevention device and the fixing metal are not limited to the above, and the net material may be fixed to a predetermined location or an inclined roof so that the net material is not blown by a gust.
[0027]
【The invention's effect】
