する。 The present invention will be described in detail below based on illustrated embodiments. In the figure, 1 is a cylindrical gutter body whose longitudinal direction is oriented in the vertical direction, and within this gutter body 1, a hollow cylindrical body 2 made of synthetic resin made of a thin film is disposed over approximately the entire length of the gutter body 1 in the vertical direction. It has been done. The upper end of the hollow cylindrical body 2 is closed to prevent rainwater from entering the inside from the upper end, and a protrusion 3 is provided on the outer peripheral surface.
are attached in a continuous spiral in the vertical direction. The lower end of the hollow cylinder 2 may be open. However, when using a vertical gutter configured in this way, the hollow cylinder body 2 is suspended from the water collector 4 or from the upper end of the gutter body 1, and the hollow cylinder body 2 is suspended inside the gutter body 1. It is used as it is, and the space between the inner surface of the gutter body 1 and the outer surface of the hollow cylindrical body 2 is used as a rainwater channel to drain rainwater. Even if the rainwater in this rainwater channel freezes and expands, this expansion is absorbed by the hollow cylindrical body 2 being compressed and contracted, thereby preventing bursting without affecting the gutter body 1. It is something. Frozen icicles also easily fall off from the hollow cylinder 2 due to the force of rotation around the hollow cylinder 2 due to the protrusions 3 on the outer surface of the hollow cylinder 2.
このように本発明にあつては雨水の凍結による
膨張を中空筒体が吸収するため樋体内で圧力が上
昇することがなく、このため樋体が破裂すること
を防止できるものであり、しかも樋体内に配した
中空筒体の外周面に凸条を上下方向に亘つて連続
する螺旋状に設けてあるので、樋体と中空筒体と
の間で凍結して氷柱ができた状態で解け始めると
きの氷柱の重量で氷柱が中空筒体の回りに回転す

面とから剥離しやすいと共にこの力で氷柱にひび

た氷柱が樋体内から脱落しやすいものである。 In this way, in the present invention, since the hollow cylindrical body absorbs the expansion due to freezing of rainwater, the pressure does not increase inside the gutter body, and therefore it is possible to prevent the gutter body from bursting. Since the outer circumferential surface of the hollow cylindrical body placed inside the body is provided with convex stripes in a spiral pattern that continues in the vertical direction, it freezes between the gutter body and the hollow cylindrical body, forming icicles that begin to thaw. Due to the weight of the icicle, the icicle receives the force of rotation around the hollow cylinder, and the icicle easily peels off from the inner surface of the gutter body and the outer surface of the hollow cylinder, and this force can cause cracks in the icicle. The icicles are crushed and the frozen icicles easily fall out of the gutter.
