Abstract: The grilled cover piece for drainage channels has a substantially horizontal wall covering the channel and a longitudinal hollow ridge which extends upwards with its top wall having eyelets or holes. The cover piece is positioned flush with or just below the level of the surface from which the water to be drained must be removed, wherein the water flows down by means of gravity into the underlying channel which conveys the water away. The cover piece is provided transversely at one end with at least one female profile and at its other end with at least one male profile complementing the female profile, so that it is possible to connect and fix together several cover pieces arranged in succession so as to cover the channel along the entire length.

Abstract: The grilled cover piece (1, 1?) for drainage channels (C), comprises a substantially horizontal wall (201) covering the channel (C) and provided with a longitudinal hollow ridge which extends upwards (301, 301?) and which with its top wall is provided with eyelets or holes (401, 2). The said cover piece emerges flush with or just below the level of the surface (SS, SS?) from which the water to be drained must be removed, said water flowing down by means of gravity into the underlying channel and being channelled and conveyed away by the latter, and being provided, transversely at one end, with at least one female profile (5, 5?) and, on its other end, with at least one male profile (105, 105?) complementing the female profile (5, 5?) at the other end, so that it is possible to connect and fix together several cover pieces (1, 1?) arranged in succession so as to cover the channel (C) along its entire length.
