Description

本発明は、雨水を有効利用するために、竪樋を流下する雨水の一部を途中で外部に取り出す雨水継手に関する。   The present invention relates to a rainwater joint for taking out a part of rainwater flowing down a kite to the outside in order to effectively use rainwater.

建築物の屋根に降り注いだ雨水は屋根の外周に沿って設けられた軒樋を伝って集水器に集められ、この集水器の下側に鉛直方向に延びて形成された竪樋に流下する。このような竪樋としてはその断面形状が円形の丸樋と四角形の角樋との2種類が使用されている。近年では、環境保全意識の高まりや節約のために、上述のような竪樋を流下する雨水の一部を取り出してタンクに貯水し、生活用水の一部に使用する雨水利用法が種々提案されており、このような場合に上下に分割した竪樋の間に連結して、この竪樋内部を流下する雨水を取水する雨水継手が種々提案されている。   Rainwater that falls on the roof of the building is collected in a water collector along the eaves along the outer periphery of the roof, and then flows down to a waterhole that extends vertically under this water collector. To do. Two types of ridges are used: a round ridge having a circular cross section and a square ridge. In recent years, in order to raise environmental conservation awareness and save, various rainwater utilization methods have been proposed in which a part of rainwater flowing down the dredging as described above is taken out and stored in a tank and used as part of daily water. In such a case, various rainwater joints have been proposed in which the rainwater flowing down through the interior of the raft is connected between the rafts divided vertically.

ところで、雨水継手を上側の竪樋と下側の竪樋との間に連結する場合に、竪樋は前述の通り角樋と丸樋の2種類あるので、上下の竪樋に連結される雨水継手も竪樋の形状に合わせて2種類用意する必要があり問題があった。そこで、雨水流下路の外側において下方に延び、丸樋の内周面と接する外周面となって丸樋が外側に嵌合して接続される丸樋接続面を有する丸樋接続部と、丸樋接続面の外側において丸樋接続面と離間して下方に延び、角樋の外周面と接する内周面となって角樋が内側に嵌合して接続される角樋接続面を有する角樋接続部とを備えた雨水継手が提案されている(例えば特許文献1)。   By the way, when connecting the rainwater joint between the upper and lower ridges, there are two types of ridges, the square ridge and the round ridge as described above. There was a problem that two types of joints had to be prepared according to the shape of the collar. Therefore, a round joint connection portion having a round joint connection surface that extends downward on the outside of the rainwater flow path and becomes an outer peripheral surface in contact with the inner peripheral surface of the round joint, and the round joint is fitted and connected to the outside. A corner having a square hook connection surface that extends downwardly away from the round hook connection face on the outside of the hook connection face, and becomes an inner peripheral face that contacts the outer peripheral face of the square hook, and the square hook is fitted and connected to the inside. There has been proposed a rainwater joint provided with a gutter connecting portion (for example, Patent Document 1).

このように構成すると、竪樋が丸樋の場合は、雨水継手の下端に形成された丸樋接続部が丸樋に挿入されて固定され、又、竪樋が角樋の場合は、雨水継手の下端に形成された角樋接続部に角樋が挿入されて固定されるので、竪樋が角樋の場合及び丸樋の場合のいずれの場合にも同じ雨水継手を用いることができる。   With this configuration, when the gutter is a round gutter, the round gutter connecting portion formed at the lower end of the rainwater joint is inserted and fixed to the round gutter, and when the gutter is a square gutter, Since a square gutter is inserted and fixed to a square gutter connecting portion formed at the lower end of the gutter, the same rainwater joint can be used in both cases where the gutter is a square gutter and a round gutter.

しかし、上述の雨水継手は、丸樋接続部を形成するとともに、この丸樋接続部の外側に丸樋接続部から離間して角樋接続部を形成する構成であるため、角樋を接続する際には、角樋接続部と丸樋接続部との間の狭い空間に角樋を挿入する必要があり、接続作業が難しい場合もある。また、角樋の内側に丸樋接続部を挿入することになるため、丸樋接続部が完全な円形では角樋内に収まらないので、丸樋接続部の一部を内側に窪ませる必要があり構造が複雑になる。   However, the above-described rainwater joint is configured to form a round rod connection portion and to form a square rod connection portion on the outside of the round rod connection portion so as to be separated from the round rod connection portion. In some cases, it is necessary to insert a square hook into a narrow space between the square hook connecting portion and the round hook connecting portion, and the connection work may be difficult. In addition, since the round rod connection part is inserted inside the square rod, the round rod connection portion does not fit inside the square rod if it is a perfect circle, so it is necessary to dent a part of the round rod connection portion inside There is a complicated structure.

そこで、本発明は、簡単な構成で竪樋が角樋の場合も丸樋の場合も接続することができ、取り付けが容易な雨水継手を提供することを目的とする。   Accordingly, an object of the present invention is to provide a rainwater joint that can be connected with a simple structure regardless of whether the ridge is a square ridge or a round ridge and can be easily attached.

A step 78 projecting downward is formed. The eye plate 72 is formed in a donut shape in which the center is opened from the open edge of the lower end of the lid portion 71 to the upper end of the cylindrical portion 75 by weaving metal threads in a net shape.

着脱部材70は、下側部材80の上端にアダプタ9を取り付けた状態で、下側部材80から水平方向に引き抜いて離脱させることができる。このように構成することで、目皿72に堆積したゴミを取り除く際に作業者が直接目皿72に触れることなく極めて簡単にゴミを取り除くことができる。また、前述の通り筒部75の下端には,切り欠き82に挿入する方向側は外周よりも内周側が下方に突出した段差77を形成し、切り欠き82への挿入方向と反対側が内周よりも外周側が下方に突出した段差78を形成しているので、切り欠き82から水平方向に筒部75を挿入して、パイプ体86の上端と固定するときに、これらの段差77,78がガイドとなってパイプ体86上端に嵌合するので、より容易に適切な位置で筒部75とパイプ体86とを連結することができる。   The detachable member 70 can be pulled out from the lower member 80 in the horizontal direction with the adapter 9 attached to the upper end of the lower member 80. With this configuration, the dust can be removed very easily without the operator directly touching the eye plate 72 when the dust accumulated on the eye plate 72 is removed. Further, as described above, the lower end of the cylindrical portion 75 is formed with a step 77 in which the inner peripheral side protrudes downward from the outer periphery on the direction side to be inserted into the notch 82, and the inner side is opposite to the insertion direction into the notch 82. Since the step 78 is formed such that the outer peripheral side protrudes downward from the outer periphery, when the cylindrical portion 75 is inserted in the horizontal direction from the notch 82 and fixed to the upper end of the pipe body 86, these steps 77, 78 Since it becomes a guide and fits to the upper end of the pipe body 86, the cylindrical portion 75 and the pipe body 86 can be more easily connected at an appropriate position.

以上のように、雨水継手1は、筒部75及びパイプ体86と外壁体85の間であって底体87の上側に取水管83に連通する取水流路Bを形成するとともに、筒部75及びパイプ体86の内側から底体87よりも下側の外壁体85内部に下側の竪樋5bに雨水を流下させる排水流路Aを形成している。   As described above, the rainwater joint 1 forms the water intake flow path B communicating with the water intake pipe 83 between the cylindrical portion 75 and the pipe body 86 and the outer wall body 85 and above the bottom body 87, and the cylindrical portion 75. In addition, a drainage flow path A is formed in the outer wall body 85 below the bottom body 87 from the inside of the pipe body 86 to allow rainwater to flow down to the lower gutter 5b.

この雨水継手1を竪樋5に連結する際には、竪樋5の形状に合わせて角樋用アダプタ9a又は丸樋用アダプタ9bを用意し、上下に水平に分断した竪樋5のうち上側の竪樋5aに用意したアダプタ9の上端を外嵌させて固定する。そして、図5に示すように下側の竪樋5bに下側部材80を下端から外嵌させて固定する。このとき、竪樋5が角樋52である場合には角樋接続面88で固定し、丸樋51である場合には丸樋接続面89で固定する。その後、図6に矢印α及びβで示すように、アダプタ9の下端と下側部材80の上端とを位置合わせして固定する。アダプタ9の下端にはアダプタ嵌合溝91が形成されており、下側部材80の上端にはアダプタ嵌合溝91に嵌合する立上がり部81が形成されているので、水平方向の位置ズレを抑制し、簡単に連結することができる。そしてその後、図6の矢印γ出示すように、下側部材80の切り欠き82とアダプタ9の下端とにより形成された開口に着脱部材70を固定して雨水継手1を完成させる。   When this rainwater joint 1 is connected to the gutter 5, a square gutter adapter 9 a or a round gutter adapter 9 b is prepared according to the shape of the gutter 5, and the upper side of the gutter 5 that is horizontally divided vertically. The upper end of the adapter 9 prepared in the flange 5a is externally fitted and fixed. Then, as shown in FIG. 5, the lower member 80 is externally fitted and fixed to the lower flange 5b. At this time, when the rod 5 is the square rod 52, it is fixed with the square rod connection surface 88, and when it is the round rod 51, it is fixed with the round rod connection surface 89. Thereafter, as indicated by arrows α and β in FIG. 6, the lower end of the adapter 9 and the upper end of the lower member 80 are aligned and fixed. An adapter fitting groove 91 is formed at the lower end of the adapter 9, and a rising portion 81 that fits into the adapter fitting groove 91 is formed at the upper end of the lower member 80. Suppress and easily connect. Then, as shown by an arrow γ in FIG. 6, the detachable member 70 is fixed to the opening formed by the notch 82 of the lower member 80 and the lower end of the adapter 9 to complete the rainwater joint 1.

以上のようにして形成された雨水継手1には、図7に示すように、屋根から軒樋3を通って集水器4に集められた雨水が、上側の竪樋5aの内周面を伝って雨水継手1の内部に流れ込む。そして、流れ込んだ雨水は外壁体85の内周面を伝って、すり鉢上に形成された蓋部71の内周面を通って目皿72上に案内される。そして目皿72は網状に形成されているので、雨水は枯葉などのゴミを目皿72で漉しとって、目皿72の下方に形成された取水流路Bに流れる。筒部75及びパイプ体86が雨水継手1の水平断面の中央に形成されており、その上端の外側に取水流路Bの入り口が形成されているので、降水量が少ない場合などのように、流下する雨水が少量の場合は、そのほとんどが取水流路Bに取り込まれて効率よく雨水を貯留することができる。また、降水量が多い場合などのように流下する雨水が大量の場合は、取水流路B側に流れきらない雨水を筒部75の上端から排水流路A側に取り込むことができる。   In the rainwater joint 1 formed as described above, as shown in FIG. 7, the rainwater collected from the roof through the eaves eaves 3 to the water collector 4 reaches the inner peripheral surface of the upper eaves 5a. Then, it flows into the rainwater joint 1. And the rainwater which flowed in is guided on the eye plate 72 through the inner peripheral surface of the cover part 71 formed on the mortar along the inner peripheral surface of the outer wall body 85. Since the eye plate 72 is formed in a net shape, the rainwater picks up dust such as dead leaves with the eye plate 72 and flows into the water intake passage B formed below the eye plate 72. Since the cylindrical portion 75 and the pipe body 86 are formed at the center of the horizontal cross section of the rainwater joint 1 and the entrance of the water intake passage B is formed outside the upper end thereof, as in the case where the amount of precipitation is small, When a small amount of rainwater flows down, most of the rainwater is taken into the intake channel B and can be stored efficiently. In addition, when there is a large amount of rainwater that flows down, such as when there is a large amount of precipitation, rainwater that cannot flow to the intake channel B side can be taken into the drain channel A side from the upper end of the cylindrical portion 75.
