にある。[Detailed description of the invention] The present invention relates to the structure of an eaves gutter joint made of synthetic resin, and has a substantially U-shaped cross section with corner portions at the bottom of both sides in the width direction, and the length of the eave gutter joint body 1 made of synthetic resin. A bellows-like portion 2 extending in the width direction is provided at the center of the direction, and metal wires 3 are intermittently embedded in the peaks and valleys of the bellows-like portion 2 in the width direction so that the metal wires 3 are located at least at the corner portions. The purpose of this joint is to have a bellows-shaped part in the center so that it can expand and contract in the longitudinal direction to absorb the expansion and contraction of the eaves gutter. To provide an eaves and gutter joint which can be formed by bending a metal wire and form a severe radius at the corner part, and which can smoothly expand and contract.
以下本考案を実施例により詳述する。The present invention will be explained in detail below with reference to Examples.
軒樋継手Ａは巾方向の両側下部にコーナ部を有する断面
略Ｕ字状で且つポリ塩化ビニルのような合成樹脂製の軒
樋継手本体１の長手方向の中央部に巾方向に亘たる蛇腹

位置するように断続的に埋入して形成しである。The eaves gutter joint A has a substantially U-shaped cross section with corner portions at the bottom of both sides in the width direction, and has a bellows extending in the width direction at the longitudinal center of the eave gutter joint body 1 made of synthetic resin such as polyvinyl chloride. A shaped part 2 is provided, and a metal wire 3 such as a steel wire is intermittently embedded in the width direction in the peaks and valleys of the bellows-shaped part 2 so that the metal wire 3 is located at least in the corner part. It is.
また上記軒樋継手Ａは次のように製造する。Further, the above eaves gutter joint A is manufactured as follows.
第４図に示すように帯状板５の中央に長手方向に亘って

面Ｕ字状になるように折曲して軒樋継手Ａを形成する。As shown in FIG. 4, the joint has a zigzag section 6 in the longitudinal direction at the center of the strip plate 5, and metal wires 3 are intermittently embedded in the width direction in the peaks and valleys of the zigzag section 6. Extrusion mold the forming band B, cut the forming band B into appropriate dimensions 1, and bend it so that it has a U-shaped cross section with the corner portions located at the bottom of both sides in the width direction to form an eaves gutter. Form joint A.
上記ジグザグ状部６に金属線３を断続的に埋入するとき

が位置するように埋入する。When the metal wire 3 is intermittently embedded in the zigzag-shaped portion 6, the metal wire 3 is placed in the corner portion when the cross section is bent into a U-shape.
Insert it so that it is located.
しかして第５図に示すようにコーナ部にシビアにアール
（Ｒ）が付けられる。As shown in FIG. 5, the corners are severely rounded.

。When the peaks are close to each other and shrunk as shown in Figure 6a, the distance between the adjacent metal wires 3 becomes Δ1 as shown in Figure 6, and the peaks and valleys become close to horizontal, as shown in Figure 7. When stretched like a, the 7th
As shown in the figure, the distance between adjacent metal wires 3 is expanded to become Δ1'.
ここでΔｌくΔ１′である。Here, Δl is Δ1'.
本考案は叙述の如く中央部に蛇腹状部があるので、長手

、伸縮がスムーズに行なわれるものである。As described above, the present invention has a bellows-like part in the center, so it can expand and contract in the longitudinal direction to absorb the expansion and contraction of the eaves gutter. Since the wire is embedded so that it is located at the corner, when manufacturing by bending the extruded band plate for joint formation, the corner can be severely rounded with the metal wire, making it easy to expand and contract. is carried out smoothly.
また蛇腹状部の山と谷とに巾方向に金属線を断続的に埋
入したので、金属線の長手方向の端部間が伸縮しやすく
て金属線を埋入してあっても蛇腹状部が軒樋継手の長手
方向に伸縮しやすいものである。In addition, since the metal wires are intermittently embedded in the width direction between the peaks and valleys of the bellows-shaped part, the ends of the metal wires in the longitudinal direction are easy to expand and contract, so even if the metal wires are embedded, the bellows-like shape The part is easy to expand and contract in the longitudinal direction of the eaves gutter joint.
つまり蛇腹状部を伸はしたときと縮めたときでは山及び
谷の周長が変わるが、金属線が断続的であると周方向に
合成樹脂のみのところが存在し、周長の変化に対応して
伸縮して蛇腹状部の軒樋継手の長手方向への伸縮がしや
すい。In other words, the circumference of the peaks and valleys changes when the bellows-like part is extended and contracted, but if the metal wire is intermittent, there will be areas where only synthetic resin exists in the circumferential direction, and it will not respond to the change in circumference. It is easy to expand and contract in the longitudinal direction of the eave gutter joint of the bellows-shaped part.
