Floor panels are supported on ledges protruding from vertical panels mounted on bolts fixed to a base plate (1) that has been cast in situ. DETAILED DESCRIPTION - Separate flat support panels (8,9) form the side walls of a drain, each element containing a ledge (12) on top of which are rested the floor panels (11). The end of the panel on the opposite side to the ledge support surface (10) is joined to the base plate using bolts fixed into the plate. The ledges can be either top edges of the panel, or a horizontal strip on one side of the panel. A sealing material is used to fill the joints between the panels and between the panels and the base plate. |
