BRANCH PART STRUCTURE OF STEEL PIPE TRUSS

摘要

PROBLEM TO BE SOLVED: To obtain the branch part structure of a steel pipe truss that easily copes with change in the installation angle between main and branch pipes at a branch part. SOLUTION: A spherical body is installed on the external surface of the main pipe, and the end part of the branch pipe is installed at the outer periphery of the spherical body thus easily coping with the change in the installation angle between the main and branch pipes without changing the circular end part of the branch pipe.
