Truss structure, structural members thereof, and a method of manufacture therefor

摘要

A joint having an improved rigidity realized by a shortened inter-joint distance and suitable for use in a truss structure is provided. A connection part is formed on the end of a pipe member to be used as a chord member. The connection part of the pipe for connecting with a parent plate for assembly of the truss structure is comprised of a tubular section formed by constrained pattern pressing of the pipe, and a flat section which is formed integral with and in close proximity to the tubular section.
