摘要: A modular truss frame system which can be assembled in a variety of sizes and configurations includes plurality interchangeable tubular chord members, as well diagonal web members. top node connection members join together predetermined ones the an end-to-end relationship. The also serve to one end each ends bottom are used opposite thereof that joined by associated connected node, means such member is attachable its respective without rotational movement member. In system, form truss-like braces for For applications where further torsional rigidity desired, nodes may or more
