9614号公報記載のように、筒壁に設けた溝に電熱
ヒーターを組み込んだものが知られている。
Traditionally, in cold regions such as Hokkaido, vertical pipes with a freeze breakage prevention function have been used, for example,
As described in Japanese Patent No. 9614, a device in which an electric heater is installed in a groove provided in the cylindrical wall is known.
しかしながら、このようなヒーター組み込み竪
樋は漏電防止処置を必要とするため構造複雑とな
り高価なものとなる上、電熱費が嵩み、停電の場
合は凍結破壊防止が全く機能しない欠点がある。 However, such a down pipe with built-in heater requires measures to prevent electrical leakage, which makes the structure complex and expensive, increases electricity costs, and has the disadvantage that freeze breakage prevention does not function at all in the event of a power outage.
本考案は叙上の問題点を解決するためになされ

る。
The present invention was made to solve the above problems, and has a simple structure and low cost.
It is designed to completely prevent freeze breakage, and its main feature is that a part of the cylinder wall is made of a soft material with high elasticity, and is made up of a bent wall with sag. It is located in the downpipe.
以下、本考案の実施例を図面を参照しながら説
明する。 Embodiments of the present invention will be described below with reference to the drawings.
第１図は本考案竪樋の一例を示す断面図であ
り、この図に示すように、硬質塩化ビニル樹脂か
らなる円筒１の一部が軟質塩化ビニル樹脂からな
る断面山形の屈曲壁２で構成されている。 FIG. 1 is a cross-sectional view showing an example of the downpipe of the present invention. As shown in this figure, a part of a cylinder 1 made of hard vinyl chloride resin is composed of a curved wall 2 with a chevron-shaped cross section made of soft vinyl chloride resin. has been done.
第２図は本考案竪樋の他の一例を示す断面図で
あり、この図に示すような、硬質塩化ビニル樹脂
からなる円筒１の一部が軟質塩化ビニル樹脂から
なる断面波形の屈曲壁２で構成されている。 FIG. 2 is a sectional view showing another example of the downpipe of the present invention. As shown in this figure, a cylinder 1 made of hard vinyl chloride resin has a bent wall 2 with a corrugated cross section made of soft vinyl chloride resin. It is made up of.
尚、かかる本考案竪樋を製造するには、クロス
ヘツドダイ若しくはオフセツトダイを使用して押
出成形することにより一挙に製造し得る。 In order to manufacture such a downpipe of the present invention, it can be manufactured all at once by extrusion molding using a crosshead die or an offset die.
筒１の材質は硬質塩化ビニル樹脂の他にアルミ
ニウム、銅或いは防錆処理を施した鉄でもよい。 The material of the tube 1 may be hard vinyl chloride resin, aluminum, copper, or iron treated with anti-rust treatment.
屈曲壁２の材質し軟質塩化ビニル樹脂の他に天
然或いは合成ゴム、ポリエチレン、SEBS等のエ
ラストマー樹脂等が使用できる。 As the material of the bending wall 2, in addition to soft vinyl chloride resin, natural or synthetic rubber, polyethylene, elastomer resin such as SEBS, etc. can be used.
又、筒１の断面形状は図示のように円形とする
他、断面四角或いは三角等の角筒状でもよい。 Further, the cross-sectional shape of the cylinder 1 is not only circular as shown in the figure, but also may be rectangular, such as square or triangular in cross-section.

る。
In the vertical gutter of the present invention, a part of the cylindrical wall is made of a soft material and is constructed with a sagging bent wall, so even if the rainwater inside freezes and expands when used in a cold region, it will not remain soft. As a result of the expansion and deformation of the curved wall made of material, it absorbs the expansion caused by freezing rainwater.

壊から免れることができる。
In the vertical gutter of this invention, even if the rainwater inside freezes and expands when used in a cold region, the bent wall deforms and absorbs the freezing and expansion of the rainwater, so that the tube wall is protected from freezing damage. can.
本考案竪樋は構造簡単であるので、従来の電熱
利用のものに比し、安価に提供でき、凍結破壊防
止が完全に機能する。 Since the structure of the downpipe of the present invention is simple, it can be provided at a lower cost than conventional ones that use electric heating, and it is fully effective in preventing freeze damage.
