<p>The present invention relates to a downpipe (10) provided with a longitudinally extending slot (16). When joining two downpipe sections together, by means of a longitudinal join or an angled join, the longitudinal slot enables the upper downpipe section to be compressed slightly so that it can be readily pushed into the lower downpipe section. Pipe-bends intended, for example, to serve as water outlets, may readily be formed by cutting a notch or recess (22', 22'') through the flanges (14) defining the slot (16) and through the laterally located legs (18) of the downpipe, and then forming a fold at the bottom of the notch in the rear side (20) of the downpipe. Pipe-bends and water outlets can be fixed in position by joining together the overlapping sides with the aid of screws, rivets or like fasteners (26). The longitudinal slot of two adjacent sections can face in opposite directions.</p> |
