Abstract

PROBLEM TO BE SOLVED: To provide a down-pipe capable of effectively increasing drainage volume by means of siphon effect.SOLUTION: A down-pipe 1 has plural overhang parts 2 formed successively in a vertical direction, which overhangs on the inner periphery for throttling a flow path area.SELECTED DRAWING: Figure 1

Description

本発明は、雨樋における竪樋に関するものである。   The present invention relates to a kite in a rain gutter.

住宅における雨樋は、一般に、屋根から流れ落ちる雨水を受ける軒樋と、集水器や呼び樋を介して軒樋に繋げられる竪樋とで構成されるが、近年、デザイン上の観点から、細めの軒樋及び竪樋が用いられることが多い。   Rain gutters in houses are generally composed of eaves that receive rainwater flowing down from the roof, and eaves that are connected to the eaves via a water collector or callout. Often eaves and cocoons are used.

しかし、細めの雨樋であると、大雨の時には排水しきれずに溢れてしまうことが生じる。   However, if it is a narrow gutter, it may overflow without being able to drain in heavy rain.

このために、サイフォンの原理を利用して単位時間当たりの排水量を増加させることで、細めの雨樋でも大雨時の雨水を好適に排水できるようにしたものが提案されている(特許文献1)。   For this reason, the thing which made it possible to drain appropriately the rainwater at the time of heavy rain even by a narrow gutter by increasing the amount of drainage per unit time using the principle of siphon has been proposed (Patent Document 1). .

これは竪樋を上下に接続するための竪樋用継手の内周面に、弾性を有する張出板を設けて、この張出板の中央部に、竪樋の内径よりも小さい内径の開口部を設けたものである。   This is because an overhanging plate having elasticity is provided on the inner peripheral surface of the rod joint for connecting the rod up and down, and an opening having an inner diameter smaller than the inner diameter of the rod is provided at the center of the overhanging plate. A part is provided.

流路面積を減少させるオリフィスを構成する上記張出板は、一定流量以上の雨水が竪樋に流入した際、抵抗となってその上方に雨水の滞留を生じさせる。そして滞留した雨水から作用する圧力(雨水の自重)がオリフィスによる抵抗力を上回れば、滞留した雨水がオリフィスを急激に流下することでオリフィスの下方側に負圧を生じさせる。この結果、オリフィスを流下する雨水の流速が増加するとともに、滞留した雨水は引っ張られて流下することになるために、単位時間当たりの流量が増大する。   The overhang plate constituting the orifice for reducing the flow path area becomes a resistance when rainwater of a predetermined flow rate or more flows into the kite and causes rainwater to stay above it. And if the pressure (self-weight of rainwater) which acts from the rainwater which stayed exceeds the resistance force by an orifice, the rainwater which stayed will flow down an orifice rapidly and will produce a negative pressure below the orifice. As a result, the flow rate of rainwater flowing down the orifice increases and the accumulated rainwater is pulled down and flows down, so that the flow rate per unit time increases.

しかし、上記従来例においては、単位時間当たりの流量増大効果が乏しく、降雨量によっては軒樋や集水器からの溢水が生じることがあり、このために、より多くの流量を単位時間内に流すことができるものが求められている。   However, in the above conventional example, the effect of increasing the flow rate per unit time is poor, and depending on the amount of rainfall, overflow from the eaves and the water collector may occur. What can be shed is required.

本発明は上記問題に鑑みてなされたもので、サイフォン効果による排水量の増大をより効果的に得ることができる竪樋を提供することを課題とする。   This invention is made | formed in view of the said problem, and makes it a subject to provide the gutter which can obtain the increase in the amount of drainage by a siphon effect more effectively.

本発明の竪樋は、内周側に張り出して流路面積を絞る張り出し部を上下に複数個連続して設けていることに特徴を有している。   The scissors of the present invention are characterized in that a plurality of projecting portions that project to the inner peripheral side and narrow the flow path area are provided continuously in the vertical direction.

本発明によれば、上下に連続する張り出し部の間で水が滞留しやすいために、サイフォン効果を早期に誘起することができ、この結果、単位時間当たりの流量を増大させることができる。   According to the present invention, since water tends to stay between the overhanging portions that are continuous in the vertical direction, the siphon effect can be induced early, and as a result, the flow rate per unit time can be increased.

本発明の一実施例の縦断面図である。It is a longitudinal cross-sectional view of one Example of this invention. 同上の平面図である。It is a top view same as the above.

以下、本発明を図示実施例に基づいて詳述すると、図1及び図2に示す竪樋1は、内周側に張り出して流路面積を絞る張り出し部2を上下に複数個(図示例では2個)連続して設けたものとなっている。また、上記張り出し部2,2は偏心したものとなっているとともに、上段側の張り出し部2と、下段側の張り出し部2との偏心方向が異なっている。   Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment. The rod 1 shown in FIGS. 1 and 2 has a plurality of projecting portions 2 that project to the inner peripheral side to narrow the flow area (up and down in the illustrated example). 2) are provided continuously. Further, the overhang portions 2 and 2 are eccentric, and the eccentric directions of the upper-stage overhang portion 2 and the lower-stage overhang portion 2 are different.

上記の張り出し部2,2は、上下端が開口する円筒状の竪樋1の内周面に、上下方向において漸次内径を変化させることで形成したスロート状のものであり、流路面積を最も小さくした部分の内径R2は、竪樋1の内径R1のほぼ半分(図示例では半分より小さい)となっている。   The projecting portions 2 and 2 are throat-shaped formed by gradually changing the inner diameter in the vertical direction on the inner peripheral surface of the cylindrical bowl 1 whose upper and lower ends are open. The inner diameter R2 of the reduced portion is almost half of the inner diameter R1 of the ridge 1 (smaller than half in the illustrated example).

また、張り出し部2は、偏心させて設けているとともに、上段側の張り出し部2の偏心方向と、下段側の張り出し部2の偏心方向とは180°異ならせて、両張り出し部2,2は逆向きに偏心したものとしてある。なお、偏心方向の異なりは、180°に限定されるものではなく、他の角度であってもよい。   The overhanging portion 2 is provided eccentrically, and the eccentric direction of the overhanging portion 2 on the upper side is different from the eccentric direction of the overhanging portion 2 on the lower side by 180 °. It is assumed to be eccentric in the opposite direction. The difference in the eccentric direction is not limited to 180 °, and may be another angle.

この竪樋1においては、雨水が流下する時、竪樋1の内面に沿って流下する雨水は、張り出し部2においてその流れの向きを変化させる。しかも、張り出し部2は上下に連続して設けられており、上段側の張り出し部2から対向面に向かった雨水は、下段側の張り出し部2において流れの向きを再度変化させる。このために、上下に並ぶ張り出し部2,2の間で雨水は滞留しやすくなる。上下に並ぶ張り出し部2,2の偏心方向を逆としている上に、張り出し部2の最小径開口部を竪樋1の内周面に内接しないようにして、竪樋1の内周面の全周にわたって張り出し部2が存在しているために、なおさら、滞留が生じやすくなっている。   In this ridge 1, when rainwater flows down, the rainwater flowing down along the inner surface of the ridge 1 changes the direction of the flow in the overhang portion 2. In addition, the overhanging portion 2 is provided continuously in the vertical direction, and rainwater directed from the upper overhanging portion 2 toward the facing surface changes the flow direction again in the lower overhanging portion 2. For this reason, rainwater tends to stay between the overhanging portions 2 and 2 arranged vertically. The eccentric direction of the overhanging portions 2 and 2 arranged vertically is reversed, and the minimum diameter opening of the overhanging portion 2 is not inscribed in the inner circumferential surface of the rod 1 so that the inner circumferential surface of the rod 1 Since the overhanging portion 2 exists over the entire circumference, the retention is more likely to occur.

そして、このような滞留がサイフォン効果を引き起こすことから、サイフォン効果を誘起しやすく、サイフォン効果による単位時間当たりの流量増を得やすいものとなっている。   And since such a stay causes a siphon effect, it is easy to induce the siphon effect, and it is easy to obtain an increase in flow rate per unit time due to the siphon effect.

また、上下に連続するとともに偏心方向が逆となっている張り出し部2,2は、図2から明らかなように、平面視において、開口部の一部が重なるものであり、サイフォン効果によって竪樋1の中心を勢いよく流下する雨水は、図中に白抜き矢印で示すように、張り出し部2,2による抵抗を受けることなく、竪樋1内を通過する。従って、サイフォン効果によるところの単位時間当たりの流量増も大きく、排水性の高いものとなっている。   Further, as is apparent from FIG. 2, the overhanging portions 2 and 2 that are continuous in the vertical direction and have the opposite eccentric directions are partially overlapped with each other in plan view. The rainwater flowing down the center of 1 passes through the ridge 1 without being subjected to resistance by the overhanging portions 2 and 2 as indicated by white arrows in the figure. Therefore, the increase in the flow rate per unit time due to the siphon effect is large and the drainage is high.

上下に並ぶ張り出し部2,2は、数cm内の間隔で上下に連続するものであることが好ましい。   The overhanging portions 2 and 2 arranged in the vertical direction are preferably continuous in the vertical direction at intervals of several centimeters.

また、竪樋1同士を繋ぐ竪樋継ぎ手として構成されたものであってもよく、また、上下に接続される2本の竪樋(一方が竪樋継ぎ手であってもよい)の上方側の竪樋1の下端部に上段側の張り出し部2を、下方側の竪樋1の上端部に下段側の張り出し部2を設けたものであってもよい。つまり、複数個の張り出し部2,2が実使用時に上下に連続する状態で配置されるものであればよい。ただし、上下に並ぶ張り出し部2,2は張り出し方向がずれていることと、竪樋1の中心にまで張り出さないものであることが望ましい。   Moreover, it may be configured as a heel joint for connecting the heels 1 to each other, or on the upper side of two heels connected to the upper and lower sides (one may be a heel joint) An upper bulge portion 2 may be provided at the lower end of the heel 1, and a lower ledge portion 2 may be provided at the upper end of the lower heel 1. That is, it is only necessary that the plurality of overhang portions 2 and 2 are arranged in a vertically continuous state during actual use. However, it is desirable that the overhanging portions 2 and 2 arranged in the vertical direction are out of the overhanging direction and do not overhang to the center of the ridge 1.
