Platform assemblies may be built up using a substantial number of inverted U- shaped vertical supports with platform hold down members that hold the platforms in place, thus avoiding slippage or pilferage. The hold down members form a unitary structure with the supports and platform assemblies to hold the platforms securely in place. The unitary structure of the scaffolding assembly with hold down members acts as a deterrent against pilferage of the platforms because the unitary structure does not allow the planks to be removed unless the platform assembly is substantially disassembled. It also reduces the steps required to assemble a secure platform assembly with hold down members thus saving time while still preventing slippage and pilferage. The hold down members have holes at one end, and these holes have a diameter slightly greater than the outer diameter (OD) of the guide pipes at the junctions between vertically extending pipes. The other end of the hold down member is substantially U-shaped and at least partially wraps around the platforms. As the scaffolding is erected, once the first, lower set of U-shaped supports and overlying planks are set in place, then the hold down members are mounted on the upwardly- extending guide pipes and across the planks. Then, when the next higher set ofU- shaped supports is mounted onto the lower set, the hold down members are held in place between the two sets of pipes, and the planks are held in place.
