Abstract A plank assembly system having two elements: one being a plank member having a horizontal walking surface, two downwardly projecting vertical legs, each vertical leg having a barbed fastener, and a downwardly projecting center support. The second element of the device is a U-shaped retaining clip having a horizontal mounting surface which is affixed to a joist system, and two upwardly extending vertical legs, each upwardly extending vertical leg having an inwardly projecting barb sized to interlock with the barb on the downwardly projecting vertical leg of the plank member. The retaining clip is also made of extruded PVC and is cut to a width sufficient for proper installation and strength of the overall platform. A plurality of retaining clips are affixed to a joist system of either metal, plastic or wood using securing means such as screws, or nuts and bolts. The retaining clips are secured to the joist system end to end along their length in sufficient number to cover the joist system so that a platform of the desired size can be created. A bead of silicone caulk is placed between the plank member and retaining clip. The plank member is then placed over the retaining clip and locked into place.
A platform assembly system to be secured to a substructure having joists comprising a plurality of plank members, each plank member having at least three downwardly projecting legs, with at least one of the downwardly projecting legs further comprising a vertical support member, the downwardly projecting legs further comprising two legs, each of which terminates in an offset barbed fastener; a plurality of retaining clips, each retaining clip having upwardly projecting legs terminating in offset barb fasteners, which coincide with a downwardly projecting leg having an offset barb fastener; whereby the plurality of retaining clips are adapted to be secured to the substructure in a number sufficient to create support for the desired finalized platform assembly, and the plank members are adapted to be secured to the retaining clips by interlocking the offset barbed fasteners of the downwardly projecting legs into the upwardly projecting offset barb fasteners of the retaining clips such that the downwardly projecting legs of the plank members align vertically above the upwardly projecting legs of the retaining clips.
