(9 and 6), by adjusting the extension ring member (2) to a second position in which
its flange (9) extends horizontally and flush with the future top surface of the floor
or roof structure, and by a second construction step during which the extension ring
member (2) is held temporarily fixed to the gully member (1) in said horizontal position
until the extension ring member (2) is finally fixed therein with the flange (9) flush
