Rainwater pipe

摘要

In the present invention, there is disclosed a rainwater pipe for attaching to faces of a roof structure chevrons, intended particularly for double sloping roofs or Italian roofs covered by a system of heat-insulating thick-walled lock-type prefabricates of plate-like shape. The rainwater pipe of the present invention consists of a pipe (1) provided in its top, at least rectangular, segment with a system of uniformly distributed parallel transverse sections (4) with a width less than 1.5 cm and greater than the width of partitions between adjacent transverse sections (4). The transverse sections (4) extend in skew manner relative to the pipe (1) longitudinal axis (1) such that the difference of axial positions of the transverse section (4) ends is greater than the pitch of the adjacent transverse sections (4). The pipe (1) is provided in the lower portion of the top section below the transverse sections (4), and namely on the side facing away from the roofed object, with uniformly distributed longitudinal sections (5) disposed on a common axis and separated from each other by bridges (6). The length of the longitudinal sections (5) is in the range of 30 cm to 50 cm and the width of the bridges (6) is in the range of 1 cm to 2 cm.
