Abstract:
1. A process of forming a dual panel composite truss comprising the steps of: assembling a truss frame on a fixture table having a plurality of truss frame clamping fixtures aligned thereon, and including the steps of forming a plurality of posts of predetermined length, each post having two end portions and forming a plurality of bent rod truss members each having two end portions and clamping each post to one said clamping fixture and attaching one end of each bent rod truss member to one end of one said clamped post and attaching the other end to the other end of an adjacent clamped post and attaching a plurality of reinforcing rods to said bent rod truss members; tensioning a plurality of pre-stressing strands in a concrete panel form; positioning said assembled truss frame in said concrete panel form having one side resting on the base thereof; attaching an end plate to each end of the assembled truss frame; filling said concrete panel form with concrete; curing the concrete in said panel form between said ends plates to form a first concrete panel on one side of said assembled truss frame; selecting a turntable having a plurality of vacuum grippers for releasably gripping said first concrete panel attached to one side of said assembled truss frame; lifting and placing said assembled truss frame and first concrete panel formed on one side thereof onto said turntable; releasably attaching said first concrete panel having said assembled truss frame attached thereto to said turntable with said plurality of vacuum grippers; turning said turntable and attached concrete panel and assembled truss frame to position the other side of said assembled truss frame in said panel form; filling said concrete panel form with concrete; and curing the concrete in said concrete panel form to form a second concrete panel on the other side of said assembled truss frame, spaced from said first concrete panel by said assembled truss frame thereby forming a dual panel composite truss.
