Abstract
The utility model relates to a steel tube fastener truss platform system which comprises a row of parallelly-arranged main beam trusses and a plurality of lines of parallelly-arranged auxiliary beam trusses, wherein the main beam trusses and the auxiliary beam trusses form a gridded framework in a criss-cross splicing mode, and platform plates are densely arranged on the gridded framework. The main beam trusses and the auxiliary beam trusses are identical in height and are connected through right-angle fasteners. Tripods of electric platforms penetrate through the main beam trusses and are hinged to the main beam trusses through pairs of angle steel.
