In the building industry, rainwater gutters are used comprising a number of elongated channels connected end to end.
Each channel extends in a given direction, has a bottom supporting face by which to mount the channel on a supporting surface, is bounded internally by a bottom wall defining a rainwater flow bed, and is bounded longitudinally by two substantially parallel end faces perpendicular to said direction.
Each channel is normally connected to each adjacent channel by a number of bolts fitted through the corresponding end faces.
Known rainwater gutters of the type described above have several drawbacks, mainly due to the way in which the adjacent channels are connected not providing for any sort of scaling, and so allowing rainwater to seep between the end faces of the adjacent channels, thus damaging the construction beneath the gutter.
