本考案は角竪樋に関し、その目的とするところ
は製造が簡単であり、しかも強度もアツプする角
竪樋を提供するにある。[Detailed Description of the Invention] The present invention relates to a rectangular vertical gutter, and its purpose is to provide a rectangular vertical gutter that is easy to manufacture and has increased strength.
本考案は角筒状のインサート金属芯材１に合成

ａの厚みは例えば0.14〜0.2mmとしてある。 In the present invention, a rectangular cylindrical insert metal core 1 is coated with a synthetic resin layer 2, and a wavy portion 3 whose wave propagation direction is in the circumferential direction is formed at the corner of the insert metal core 1 over the entire length in the length direction. This relates to a rectangular vertical gutter. Hereinafter, the present invention will be explained in detail based on illustrated embodiments. 1 is an insert metal core material, which is made by bending a metal plate 1a made of steel or the like into a rectangular tube shape so that both ends overlap. The corrugated portions 3 are formed in advance at the portions of the metal plate 1a that will become the corners of the insert metal core material 1, so that the work of forming the corners when bending the metal plate 1a is facilitated. metal plate 1
The thickness of a is, for example, 0.14 to 0.2 mm.
尚、波状部３はインサート金属芯材１の周方向
を波の進行方向としてインサート金属芯材１の長
手方向全長に亘つて形成してある。インサート金
属芯材１の内外両周面には塩化ビニル樹脂などの
合成樹脂層２を被覆してある。 The wavy portion 3 is formed over the entire length of the insert metal core 1 in the longitudinal direction with the circumferential direction of the insert metal core 1 as the wave propagation direction. Both the inner and outer peripheral surfaces of the insert metal core material 1 are coated with a synthetic resin layer 2 such as vinyl chloride resin.
本考案は叙述のように、インサート金属芯材の
角部に周方向を波の進行方向とする波状部を長さ
方向全長に亘つて形成したので、インサート金属
芯材に曲成する前の金属板に予め波状部を入れて
おけば、波状部の屈曲性の良さを利用して角部の
曲成が容易となつて製造能率が向上し、しかも波
状部が補強リブとして機能して強度も向上すると
いう利点がある。 As described above, in the present invention, a wavy portion is formed at the corner of the insert metal core material over the entire length in the circumferential direction, so that the metal before being bent into the insert metal core material If the corrugated parts are added to the plate in advance, the bending of the corners will be easier by taking advantage of the good flexibility of the corrugated parts, improving manufacturing efficiency.In addition, the corrugated parts will function as reinforcing ribs, increasing the strength. It has the advantage of improving.
