Description

本発明は、ビニールハウス等に配設される樋の端部に設けられる集水ダクトに関する。   The present invention relates to a water collection duct provided at an end of a ridge disposed in a greenhouse or the like.

連棟型ビニールハウスの場合、屋根から流下する雨水や融雪水等の水をそのまま垂れ流すと、屋根と屋根との間に形成される谷部に溜まり、妻面側に流れなくなり、屋根を構成する樹脂フィルム材が弛んだり、破れたりして、ビニールハウス内にこれらの水が流下することになる。そのため、従来、この谷部に谷樋部材を取り付けて、これらの水を所定位置に排水するようにしている（例えば特許文献１，２参照。）。   In the case of a multi-storey type greenhouse, if rainwater or snowmelt water that flows down from the roof flows down as it is, it collects in the valley formed between the roofs and does not flow to the wife side, forming the roof The resin film material to be loosened or torn will cause these waters to flow into the greenhouse. Therefore, conventionally, a trough member is attached to this trough, and the water is drained to a predetermined position (see, for example, Patent Documents 1 and 2).

また、ビニールハウスは、結露現象により屋根の樹脂フィルム材の内面に大量の水滴が付着し、これが樹脂フィルム材を伝いながらビニールハウス内に落下すると、作物の根腐れが発生したり、湿度が高くなって作物に病気が発生したりする。そのため、従来、谷部の谷樋部材の下方にも樋を設ける二重樋を採用し、落下する水滴を受けて排水するようにしている（特許文献１参照。）。   Also, in greenhouses, a large amount of water droplets adhere to the inner surface of the resin film material on the roof due to condensation, and if this falls into the greenhouse while passing through the resin film material, crop root rot will occur or the humidity will be high. The crops become sick. Therefore, conventionally, a double gutter provided with a gutter also below the gutter member in the trough is used to receive and drain the falling water droplets (see Patent Document 1).

ところで、二重樋の樋の端部は集水ダクトに挿入されており、二重樋によって受けた水滴は樋の端部から集水ダクトに集められて、所定位置に排水されるようになっている。ところが、水滴は樋の端部において表面張力により表側から裏側へ端部を伝って回り込んでしまい、集水ダクト内に落下せず、樋の裏側を逆流してビニールハウス内に落下するという現象が発生する。   By the way, the end of the double reed ridge is inserted into the water collection duct, and the water droplets received by the double reed are collected from the end of the reed into the water collection duct and drained to a predetermined position. ing. However, the water droplets travel around the edge from the front side to the back side due to surface tension at the edge of the ridge, and do not fall into the water collection duct, but flow back into the greenhouse and fall into the greenhouse. Will occur.

そこで、本発明においては、表面張力により樋の裏側へ回り込んで逆流することを防止した集水ダクトを提供することを目的とする。   Therefore, an object of the present invention is to provide a water collection duct that prevents backflow by flowing around to the back side of the bag due to surface tension.

本発明の集水ダクトは、樋の端部が挿入される集水ダクトであって、樋の端部からの排水を集水する集水部と、樋の端部が集水部の上で浮いた状態となるように樋を保持する樋保持部と、樋の集水部の上で浮いた状態となった部分の下面に当接する舌片とを有するものである。   The water collection duct of the present invention is a water collection duct into which the end of the dredger is inserted, the water collection unit collecting the drainage from the end of the dredge, and the end of the dredge on the water collection unit. It has a heel holding portion that holds the heel so as to be in a floating state, and a tongue piece that comes into contact with the lower surface of the portion that is in a floating state on the water collecting portion of the heel.

本発明の集水ダクトによれば、樋の端部において表面張力により表側から裏側へ回り込んだ水滴は、この樋の集水部の上で浮いた状態となった部分の下面に舌片が当接しているため、表面張力によりこの舌片に沿って樋の集水部へと導かれ、集水されて所定位置に排水される。   According to the water collecting duct of the present invention, the water droplets that have turned from the front side to the back side due to surface tension at the end of the ridge have tongues on the lower surface of the portion that has floated on the water collecting portion of the ridge. Since they are in contact with each other, they are guided along the tongue pieces to the water collecting portion of the bag by the surface tension, and are collected and drained to a predetermined position.

本発明の集水ダクトによれば、樋の端部において表面張力により表側から裏側へ回り込んだ水滴は舌片に沿って樋の集水部へと導かれ、集水されて所定位置に排水されるため、樋の裏側へ回り込んで逆流することを防止することができ、ビニールハウス内に落下することを防止することができる。そのため、樋と集水ダクトとの接合部に接着剤やコーキング剤等を使用して止水することが不要となり、集水ダクトに樋を差し込むだけで施工することが可能となる。   According to the water collecting duct of the present invention, water droplets that have turned around from the front side to the back side due to surface tension at the edge of the ridge are guided to the water collecting section of the ridge along the tongue piece, and are collected and drained to a predetermined position. Therefore, it can be prevented that it flows back to the back side of the bag and flows backward, and can be prevented from falling into the greenhouse. Therefore, it is not necessary to stop water using an adhesive or a caulking agent or the like at the joint between the dredging and the water collecting duct, and construction can be performed simply by inserting the dredging into the collecting duct.

図１に示すように、本発明の実施の形態における集水ダクト１は、樋２の端部が挿入されて使用されるものである。樋２は、例えば、図示しないビニールハウス等に略水平（水を一方向へ導くために若干傾斜させている場合を含む。）に延設されたものであり、特に結露現象により屋根の樹脂フィルム材の内面に付着した水滴を受けるために設けられたものである。なお、本実施形態においては、樋２は断面半円状であるが、他の断面形状のものを使用することも可能である。   As shown in FIG. 1, a water collection duct 1 according to an embodiment of the present invention is used by inserting an end portion of a ridge 2. The eaves 2 are, for example, extended substantially horizontally in a greenhouse (not shown) (including the case where the water is slightly inclined to guide water in one direction). It is provided to receive water droplets adhering to the inner surface of the material. In the present embodiment, the ridge 2 has a semicircular cross section, but other cross sections may be used.

図２〜図１０に示すように、集水ダクト１は、樋２の端部２ａからの排水を集水する集水部１０と、樋２を保持する樋保持部１１と、樋２の端部２ａの下面２ｂに当接する舌片１２と、樋２の先端に当接して位置決めするストッパ１３と、集水部１０から水を排水する排水部１４とを有する。集水部１０は、樋２の端部２ａからの排水をその下方で受けて集水する空間であり、排水部１４に向かって先細り形状となっている。舌片１２は、集水部１０の中に立設されている。   As shown in FIGS. 2 to 10, the water collecting duct 1 includes a water collecting portion 10 that collects drainage from the end portion 2 a of the dredge 2, a dredge holding portion 11 that holds the dredge 2, and an end of the dredge 2. It has a tongue piece 12 that comes into contact with the lower surface 2b of the part 2a, a stopper 13 that comes into contact with the tip of the ridge 2 and is positioned, and a drainage part 14 that drains water from the water collection part 10. The water collecting portion 10 is a space that receives the drainage from the end 2 a of the trough 2 below and collects water, and has a tapered shape toward the drainage portion 14. The tongue piece 12 is erected in the water collecting portion 10.

樋保持部１１は、樋２の外形に対応する形状、すなわち本実施形態においては断面半円状を有し、樋２の端部２ａが集水部１０の上で浮いた状態となるように保持するものである。樋２の端部２ａが集水部１０の上で浮いた状態とは、図１０に示すように、樋２の端部２ａが樋保持部１１から集水部１０内に突出しており、この突出した下面２ｂの部分において舌片１２以外に接していない状態をいう。   The eaves holding part 11 has a shape corresponding to the outer shape of the eaves 2, that is, in the present embodiment, has a semicircular cross section, and the end 2 a of the eaves 2 is in a floating state on the water collecting part 10. It is to hold. As shown in FIG. 10, the state in which the end 2 a of the trough 2 floats on the water collecting portion 10 means that the end 2 a of the trough 2 protrudes from the trough holding portion 11 into the water collecting portion 10. The state which is not touching other than the tongue piece 12 in the part of the protruded lower surface 2b is said.

舌片１２は、図７に示すように、上端面が樋２の外形に沿う形状に形成されており、樋２の集水部１０の上で浮いた状態となった部分の下面に当接している。また、図７に示すように、舌片１２の左右両端部分には、集水部１０の内壁面との間に隙間１０ａが設けられており、この舌片１２によって集水部１０を仕切ることがないようにしている。ストッパ１３は、樋２の端部２ａを集水ダクト１内に挿入した際、その先端が当接した状態で、樋２の端部２ａに水が通過する空間が確保されるようにしたものである。   As shown in FIG. 7, the tongue piece 12 has an upper end formed in a shape that follows the outer shape of the ridge 2, and abuts against the lower surface of the portion that has floated on the water collecting portion 10 of the ridge 2. ing. As shown in FIG. 7, a gap 10 a is provided between the inner wall surface of the water collecting portion 10 at both left and right end portions of the tongue piece 12, and the water collecting portion 10 is partitioned by the tongue piece 12. There is no such thing. The stopper 13 is designed to secure a space for water to pass through the end portion 2a of the ridge 2 in a state in which the tip end abuts when the end portion 2a of the ridge 2 is inserted into the water collecting duct 1. It is.

上記構成の集水ダクト１では、樋２の端部２ａにおいて表面張力により表側から裏側へ回り込んだ水滴は、この樋２の集水部１０の上で浮いた状態となった部分の下面２ｂに舌片１２が当接しているため、表面張力によりこの舌片１２に沿って樋２の集水部１０へと導かれ、集水されて所定位置に排水される。そのため、この集水ダクト１では、水滴が樋２の裏側へ回り込んで逆流することを防止することができ、ビニールハウス内に落下することを防止することができる。したがって、この集水ダクト１では、樋２と集水ダクト１との接合部に接着剤やコーキング剤等を使用して止水することが不要であり、集水ダクト１に樋２を差し込むだけで施工することが可能となる。   In the water collecting duct 1 having the above-described configuration, the water droplets that have turned around from the front side to the back side due to surface tension at the end 2a of the eaves 2 are floated on the water collecting portion 10 of the eaves 2 under the lower surface 2b. Since the tongue piece 12 is in contact with the surface, the surface piece is guided along the tongue piece 12 to the water collecting portion 10 of the ridge 2 by the surface tension, and is collected and drained to a predetermined position. Therefore, in this water collection duct 1, it is possible to prevent water droplets from flowing back to the back side of the bowl 2 and flowing back, and to prevent falling into the greenhouse. Therefore, in this water collection duct 1, it is not necessary to stop water using an adhesive or a caulking agent or the like at the joint between the water bottle 2 and the water collection duct 1, and only the water bottle 2 is inserted into the water collection duct 1. It becomes possible to construct with.

なお、上記構成の集水ダクト１は、例えば、図１１に示す樋装置との組み合わせて使用される。図１１は図１の集水ダクト１と組み合わされる樋装置の例を示す縦断面図である。   In addition, the water collection duct 1 of the said structure is used in combination with the dredging apparatus shown in FIG. 11, for example. FIG. 11 is a longitudinal sectional view showing an example of a dredging device combined with the water collecting duct 1 of FIG.

図１１に示す樋装置２１は、連棟型ビニールハウスの屋根２２ａと屋根２２ｂとの間に形成される谷部２３を構成する谷樋部材２４の下方に配設されている。屋根２２ａ，２２ｂは、アーチパイプ２５、樹脂フィルム材２６や、図示しないシート材止め条材等を用いて形成されている。また、谷部２３の下方には、谷部２３の形成方向に所定間隔で支柱２７が配置されている。   The dredge device 21 shown in FIG. 11 is disposed below a trough member 24 that constitutes a trough 23 formed between the roof 22a and the roof 22b of the continuous greenhouse. The roofs 22a and 22b are formed using an arch pipe 25, a resin film material 26, a sheet material stopper material (not shown), and the like. Further, below the troughs 23, support columns 27 are arranged at predetermined intervals in the forming direction of the troughs 23.

樋装置２１は、谷部２３に沿ってその下方に配される樹脂フィルム材３０と、谷部２３の下方に谷部２３の形成方向に沿って延設される樋部材３１とを有する。樋部材３１は、断面半円状の樋本体部３１ａと、樹脂フィルム材３０の下端部が内挿される断面凹状の耳部３１ｂとを備える。   The scissor device 21 has a resin film material 30 disposed below the trough 23 and a scissor member 31 extending below the trough 23 along the direction in which the trough 23 is formed. The eaves member 31 includes an eaves body portion 31a having a semicircular cross section and an ear portion 31b having a recessed cross section in which the lower end portion of the resin film material 30 is inserted.

耳部３１ｂは、樋本体部３１ａの両上端部に設けられ、樋部材３１の内側に向かって断面凹状の開口面が形成されている。また、耳部３１ｂの上縁部には、耳部３１ｂ内に嵌合されるゴム紐材３２が容易に抜け出さないように鉤状の抜止部３１ｃが形成されている。ゴム紐材３２は、耳部３１ｂに内挿された樹脂フィルム材３０の上から挿入され、樹脂フィルム材３０を固定するものである。樋部材３１は、支柱２７に対し、谷部２３を挟んで両側に並設されている。前述の集水ダクト１は、この樋部材３１の先に設置される。   The ear portions 31b are provided at both upper ends of the heel body portion 31a, and an opening surface having a concave cross section is formed toward the inside of the heel member 31. A hook-shaped retaining portion 31c is formed on the upper edge portion of the ear portion 31b so that the rubber string member 32 fitted into the ear portion 31b does not easily come out. The rubber string material 32 is inserted from above the resin film material 30 inserted in the ear portion 31b, and fixes the resin film material 30. The eaves member 31 is juxtaposed on both sides of the support column 27 with the valley portion 23 in between. The water collecting duct 1 described above is installed at the tip of the flange member 31.

上記構成の樋装置２１では、屋根２２ａと屋根２２ｂとの間に形成された谷部２３に沿ってその下方に樹脂フィルム材３０が配され、この樹脂フィルム材３０の下端部が樋部材３１の耳部３１ｂ内に内挿され、この耳部３１ｂ内の樹脂フィルム材３０の上からゴム紐材３２が挿入されることにより、樹脂フィルム材３０が樋部材３１の耳部３１ｂ内に固定される。一方、樹脂フィルム材３０の上端部は、パッカー２８等の固定具によりアーチパイプ２５に固定されている。これにより、屋根２２ａ，２２ｂの内面から落下する水滴を、樋部材３１の真上からだけでなく、樹脂フィルム材３０により広範囲から受けて、樋部材３１に導き、集水ダクト１から所定位置に排水することが可能となっている。   In the dredge device 21 having the above-described configuration, the resin film material 30 is disposed below the trough portion 23 formed between the roof 22a and the roof 22b. The resin film material 30 is fixed in the ear portion 31b of the heel member 31 by being inserted into the ear portion 31b and inserting the rubber string material 32 from above the resin film material 30 in the ear portion 31b. . On the other hand, the upper end portion of the resin film material 30 is fixed to the arch pipe 25 by a fixing tool such as a packer 28. As a result, water drops falling from the inner surfaces of the roofs 22a and 22b are received not only from directly above the eaves member 31 but also from a wide range by the resin film material 30 and guided to the eaves member 31 to be in a predetermined position from the water collecting duct 1. It is possible to drain.

また、本実施形態における樋装置２１では、支柱２７と支柱２７との間であって、並設された樋部材３１の間にも、同様に樹脂フィルム材３４を配することが可能である。この樹脂フィルム材３４の端部は、それぞれの樋部材３１の内側の耳部３１ｂ内に内挿され、この耳部３１ｂ内の樹脂フィルム材３４の上からゴム紐材３２が挿入されることにより、樹脂フィルム材３４が樋部材３１の耳部３１ｂ内に固定される。したがって、この樹脂フィルム材３４によっても、屋根２２ａ，２２ｂの内面から落下する水滴を受けて樋部材３１にそれぞれ導き、集水ダクト１から所定位置に排水することが可能となっている。   Moreover, in the dredge apparatus 21 in this embodiment, the resin film material 34 can be similarly arranged between the struts 27 and the struts 27 and between the juxtaposed member 31 arranged side by side. The end portion of the resin film material 34 is inserted into the inner ear portion 31b of each collar member 31, and the rubber string material 32 is inserted from above the resin film material 34 in the ear portion 31b. The resin film material 34 is fixed in the ear portion 31 b of the flange member 31. Therefore, the resin film material 34 can also receive water droplets falling from the inner surfaces of the roofs 22a and 22b, guide them to the gutter member 31, and drain the water collecting duct 1 to a predetermined position.

また、本実施形態における樋装置２１では、ゴム紐材３２を樋部材３１の耳部３１ｂ内に挿入するだけで簡単に樹脂フィルム材３０，３４を固定することができるとともに、不要時にはゴム紐材３２を樋部材３１の耳部３１ｂ内から取り外すだけで簡単に樹脂フィルム材３０，３４の固定を解くことができるので、必要に応じて谷部２３の下方に配される樹脂フィルム材３０，３４の取り付けおよび取り外しを容易に行うことが可能となっている。   Further, in the scissor device 21 in the present embodiment, the resin film materials 30 and 34 can be easily fixed by simply inserting the rubber cord material 32 into the ear portion 31b of the scissors member 31, and the rubber cord material can be used when not required. Since the resin film materials 30 and 34 can be easily unfixed simply by removing the 32 from the ear portion 31b of the flange member 31, the resin film materials 30 and 34 disposed below the valley portion 23 as necessary. Can be easily attached and detached.

また、本実施形態における樋装置２１では、屋根２２ａ，２２ｂから降りてくる冷気が、その下方に配された樹脂フィルム材３０，３４によって遮断されるため、ビニールハウス内の環境へ悪影響を及ぼすのを防止することができる。   Moreover, in the dredge apparatus 21 in this embodiment, since the cold air which descends from the roofs 22a and 22b is interrupted | blocked by the resin film materials 30 and 34 distribute | arranged to the downward direction, it has a bad influence on the environment in a greenhouse. Can be prevented.

さらに、本実施形態における樋装置２１では、寒冷地において屋根２２ａと屋根２２ｂとの間に形成された谷部２３に溜まった雪を溶かすために、屋根２２ａ，２２ｂの谷部２３とその下方に配された樹脂フィルム材３０，３４との間のわずかな空間だけを暖めるだけで良いため、効率良く短時間で融雪することが可能となっている。   Furthermore, in the dredge apparatus 21 in this embodiment, in order to melt the snow accumulated in the valley portion 23 formed between the roof 22a and the roof 22b in the cold region, the valley portion 23 of the roofs 22a and 22b and below the valley portion 23. Since it is only necessary to warm a small space between the resin film materials 30 and 34 disposed, it is possible to melt snow efficiently and in a short time.

本発明の集水ダクトは、ビニールハウス等に配設される樋の端部に設けられる集水ダクトとして有用である。   The water collection duct of the present invention is useful as a water collection duct provided at the end of a cage disposed in a greenhouse or the like.
