SCREW CONNECTION BETWEEN TUBULAR BARS AND ATTACHMENT CONNECTORS IN SPACE FRAMEWORKS

摘要

A bolt connection between tubular rods and junctions in three-dimensional frameworks wherein the tubular rods are of constant diameter along their entire length and it continues the same beyond the hook-up parts at the tubular rod ends as far as those ends of the hook-up parts which are assembled each with one drive sleeve, and the smallest outside diameter of the drive sleeves being equal to or exceeding that of the tubular rods and of the hook-up parts.
