Modular truss frame system

摘要

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