Description

本発明は、雨水が貯留可能な雨樋装置及びそれに用いる軒樋に関する。   The present invention relates to a rain gutter apparatus capable of storing rain water and an eaves used for the gutter device.

従来、屋根の軒先から流れ落ちる雨水を軒樋で受け下方に排水する雨樋装置として、例えば、図3に示すように家屋の屋根の軒先に取付けられた軒樋aに呼び樋や竪樋を竪樋継手によって接続し、外壁に沿って垂下させて地中に埋設された排水管に接続しているのが一般的である。 Conventionally, as a rain gutter device that receives rain water flowing down from the eaves of the roof with an eaves and drains it downward, for example, as shown in FIG. 3, a call and a b are attached to the eaves a attached to the eaves of the roof of the house. Generally, it is connected by a saddle joint c and is suspended along the outer wall d and connected to a drain pipe e buried in the ground.

ところで、上記雨樋装置において、軒樋aで処理できる水の流量を増やすには、軒樋a自体の断面寸法を大きくしたり、呼び樋や竪樋の口径の拡大、本数の増加を図る必要がある。しかし、これらは、コストの上昇、見栄えの低下といった問題がある。 Incidentally, in the guttering system, to increase the flow rate of water that can be processed by eaves gutters a, reduce or increase the cross-sectional dimension of the eaves gutters a itself, called the expansion of the diameter of the gutter and Tatetoi b, and increase in number There is a need. However, these have problems such as an increase in cost and a decrease in appearance.

そこで、口径の拡大や本数を増やすことがなく排水処理量を増加させる雨樋装置として、特許文献1〜2に記載されているようなサイホン式排水システムが提案されている。
即ち、特許文献1には、軒樋の底面に、軒樋よりも小さくかつ竪樋よりも大きな断面寸法を有した凹部状の落し口を設け、この落し口の底面に竪樋を接続したサイホン式排水システムによる雨樋装置が記載されている。
また、特許文献2には、樋状体に設けられた落とし口の上方に、二枚の平行な平板を互いに間隔をおいて配設した屋根取水口が記載されている。

Therefore, siphon-type drainage systems such as those described in Patent Documents 1 and 2 have been proposed as rain gutter devices that increase the amount of drainage without increasing the diameter or number of pipes.
That is, Patent Document 1 provides a siphon in which a recess-shaped drop opening having a cross-sectional dimension smaller than an eave basket and larger than that of the eave basket is provided on the bottom surface of the eave basket, and a hook is connected to the bottom surface of the drop opening. A rain gutter device with a water drainage system is described.
Patent Document 2 describes a roof intake port in which two parallel flat plates are spaced apart from each other above a drop port provided in a bowl-shaped body.
Japanese Patent Laid-Open No. 9-111972 (FIG. 1) Japanese translation of PCT publication No. 8-506396 (FIG. 1)

しかしながら、上記特許文献1〜2に記載された排水方式は、いずれもサイホン式排水システムの構造によるものであるが、特許文献1に記載された雨樋装置にあっては、凹部状の落し口としては大きな深さを有したものでないと効果が期待できない。軒樋の底面に大きな深さを有した凹部状の落し口を設けると、軒樋を下方から見ると大きな落とし口が見えて外観上見栄えがよくない。
また、特許文献2に記載された雨樋装置においては、平板に落ち葉等の塵が引っ掛かり落とし口にゴミ詰まりを発生し易く、塵の除去が煩瑣である。更にまた、落とし口の排水構造が複雑でコストが上昇するという問題点がある。
However, the drainage methods described in Patent Documents 1 and 2 are all based on the structure of the siphon drainage system. However, in the rain gutter device described in Patent Document 1, a recess-shaped drop mouth is used. However, the effect cannot be expected unless it has a great depth. When a recess-shaped drop opening having a large depth is provided on the bottom of the eaves bowl, when the eaves bowl is viewed from below, a large drop opening is seen and the appearance is not good.
Moreover, in the rain gutter device described in Patent Document 2, dust such as fallen leaves is easily caught on the flat plate, and clogging of dust is likely to occur at the dropping port, and dust removal is troublesome. Furthermore, there is a problem that the drainage structure of the outlet is complicated and the cost increases.

本発明は、このような事情に鑑みて、低コストで見栄えを低下させることなく排水処理量を増加させることのできる雨樋装置を提供することを目的としている。   In view of such circumstances, an object of the present invention is to provide a rain gutter apparatus that can increase the amount of wastewater treated at low cost and without reducing appearance.

このような目的を達成するために、請求項1に記載の発明に係わる雨樋装置(以下、「請求項1の雨樋装置」と記す)は、軒先に軒樋が配設されており、該軒樋の底壁部に排水ドレンが設けられ、この排水ドレンには下方に竪樋がエルボを介して接続され、竪樋の下端部が地中に埋設された排水管に排水管カバーを介して接続されている雨樋装置において、排水管カバー内には竪樋の下端部から排水される雨水を受水する有底筒体が配設され、有底筒体内には竪樋の下端部が有底筒体の開口水平面より下方に挿入されていることを特徴としている。   In order to achieve such an object, the rain gutter apparatus according to the invention described in claim 1 (hereinafter referred to as “the gutter apparatus of claim 1”) is provided with an eave gutter at the eaves, A drainage drain is provided on the bottom wall of the eaves, and a drainage pipe is attached to the drainage drain connected to the drainage drain via an elbow and the lower end of the fence is buried in the ground. In the rain gutter apparatus connected via the bottom, a bottomed cylinder for receiving rainwater drained from the bottom end of the gutter is disposed in the drain pipe cover, and the bottom end of the gutter is disposed in the bottomed cylinder. The portion is inserted below the open horizontal surface of the bottomed cylindrical body.

本発明の雨樋装置によれば、軒先に軒樋が配設されており、該軒樋の底壁部に排水ドレンが設けられ、この排水ドレンには下方に呼び樋と竪樋がエルボを介してこの順に接続され、竪樋の下端部が地中に埋設された排水管に排水管カバーを介して接続されている雨樋装置において、排水管カバー内には竪樋の下端部から排水される雨水を受水する有底筒体が配設され、有底筒体内には竪樋の下端部が有底筒体の開口水平面より下方に挿入されているので、排水ドレンから排水されて竪樋に流れ込んた雨水は、有底筒体内を満水にすることになる。そのため、竪樋の下端部は満水状態の有底筒体により水封されることになるから、雨水は、竪樋内でサイホン現象をおこして排水管側に排水され、排水処理量を増加させることができる。   According to the rain gutter apparatus of the present invention, the eaves is disposed at the eaves edge, and the drainage drain is provided on the bottom wall portion of the eaves eaves. In the rain gutter device in which the lower end of the dredge is connected to the drain pipe buried in the ground via the drain pipe cover, the drain pipe cover is drained from the lower end of the dredge. A bottomed cylinder that receives rainwater is disposed, and the bottom end of the tub is inserted below the open horizontal surface of the bottomed cylinder in the bottomed cylinder, so that it is drained from the drainage drain. Rainwater that has flowed into the reed fills the bottomed cylinder. As a result, the bottom end of the dredge is sealed with a full-bottomed bottomed cylinder, so rainwater siphons inside the dredge and is drained to the drain pipe, increasing the amount of wastewater treated. be able to.
