An improved assembly includes a framwork, two interconnected similar plastic planks, and a fastener for attaching the planks to the framework. The improvement wherein each of the planks includes an L-shaped outwardly projecting plate and a first abutment portion on a side thereof, and a U-shaped projecting plate and a second abutment portion on the opposite side thereof. The L-shaped projecting plate can be held within and on the U-shaped projecting plate to provide a water-proof effect when the planks are interconnected side by side. A U-shaped cover is sleeved on the U-shaped projecting plate so as to provide an additional water-proof effect.
