<p>A gutter system comprises a plurality of prefabricated gutter elements having an essentially U-shaped cross section. One of the legs (2) of a gutter element is considerably longer than the other (3), and this long leg (2) is attachable on the roof. Each gutter element comprises, at both ends thereof, an end wall (9) that is preferably integral with the gutter element and that comprises a coupling means for connecting a coupling piece (11) for connecting a discharge pipe (13) for precipitation water, said coupling piece (11) being connectable in any desired rotational position with respect to the longitudinal direction of the gutter element. The coupling piece (11) can be a T-coupling piece, mountable between two successive gutter elements. Each connecting means can be formed by a tube stub, the coupling piece (11) then being a piece of tubing.</p> |
