【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、補強芯材に熱可塑性樹脂が被覆されてなる
軒樋に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an eaves gutter in which a reinforcing core material is coated with a thermoplastic resin.
最近、軒先への軒樋の固定は、軒樋の外周面に沿って
支持する受け金具に替わって、軒樋の上方から樋耳部を
係止する吊り金具が好んで用いられている。Recently, in order to fix the eaves gutter to the eaves, instead of the receiving metal fitting that supports along the outer peripheral surface of the eaves gutter, a hanging metal fitting that holds the gutter ear part from above the eaves gutter is preferably used.
このような吊り金具により軒先に固定される軒樋とし
ては、例えば、実開昭62-4529号公報に記載のような内
吊り方式の軒樋が知られている。As an eaves trough fixed to the eaves by such a hanging fitting, for example, an inner hanging type eaves trough as disclosed in Japanese Utility Model Laid-Open No. 62-4529 is known.
この内吊り方式の軒樋は、樋本体部の側壁の上端部内
側に向けられた樋耳部に、樋本体部の内側に向けて開口
す係止溝が設けられたもので、樋耳部内側の係止溝に吊
り金具を係止することにより軒先に固定することがで
き、吊設した軒樋を軒下から見ても吊り金具が軒樋内に
隠れてしまい美観性を満足させるものである。This inner suspension type eaves gutter has a gutter ear part that is directed to the inside of the upper end of the side wall of the gutter body, and has a locking groove that opens toward the inside of the gutter body. It can be fixed to the eaves by locking the hanging metal fittings in the inner locking groove, and even if the hanging eaves gutter is viewed from under the eaves, the hanging metal fittings are hidden in the eaves gutter, which satisfies the aesthetics. is there.
ところで、内吊り方式の軒樋は、一般に塩化ビニル樹
脂などの熱可塑性樹脂で長尺に押出成形され広く使用さ
れている。しかし、かかる熱可塑性樹脂の軒樋は、熱伸
縮が大きく剛性が小さいため、四季や昼夜の気温変化に
より変形し、またひび割れが発生し易いという欠点があ
る。By the way, the inner hanging type eaves gutter is generally extruded in a long length from a thermoplastic resin such as vinyl chloride resin and is widely used. However, such a thermoplastic resin eaves gutter has a drawback that it is easily deformed due to temperature changes during the four seasons or day and night and is easily cracked because of its large thermal expansion and contraction and low rigidity.
このような欠点を改良した軒樋としては、例えば、実

樋が提案されている。この場合、補強芯材は一般に樋本
体部のみならず樋耳部へも延出されこの部分を強化して
いる。As an eaves trough that has improved such a defect, for example, as described in JP-B-62-42019, an eaves trough formed by melt extrusion coating a thermoplastic resin on a reinforcing core made of a fibrous base material. Proposed. In this case, the reinforcing core material is generally extended not only to the gutter body portion but also to the gutter ear portion to reinforce this portion.
ところで、かかる従来の補強芯材を用いた軒樋にあっ

吊り金具の抜けが発生する場合があり、樋耳部の機能が
充分に発揮されない。By the way, in the eaves gutter using such a conventional reinforcing core material, strength is insufficient especially at the locking end portion of the gutter ear portion having the locking groove. Therefore, when the eaves gutter is exposed to direct sunlight and becomes hot, the locking end part of the gutter ear part may be deformed, and the gutter ear part may open or the hanging metal fitting may come off. Not fully exerted.

った。In addition, the reinforcing core material made by impregnating the reinforcing fiber material with the synthetic resin is formed from the long sheet shape to the eaves gutter shape,
The long sheet may have dimensional variations in the width direction, and the side edges of the sheet may be uneven. When such an eaves trough-shaped reinforcing core material is introduced into the die slit b of the crosshead mold a as shown in FIG. 8 and the reinforcing core material c is melt-extruded and coated with the thermoplastic resin, The side edge of the material c, that is, the end edge e of the trough core material d may contact the end wall f of the die slit b, and the trough may be deformed and cut. Further, if the space between the end edge portion e of the ear core material c and the end wall f of the die slit b is too large, the molten resin in the coating flows back to the side where the reinforcing core material c is introduced, so-called back flow. There is a problem that continuous molding is difficult due to a phenomenon.
