Truss device

Abstract

A truss device comprises a set of elongate tube bodies ( 10 ) which extend parallel to each other in a longitudinal direction and which are connected spatially separated from each other by bars ( 30 ). The tube bodies ( 10 ) are provided or at least can be provided at opposite outer ends with coupling means ( 20 ) for a releasable coupling to a tube body of a further truss device. The bars ( 30 ) have a polygonal cross-section and at their end surfaces are connected substantially along at least one side of a periphery of this cross-section to an adjacent tube body along an at least in projection linear connection.
