JOINT SECTION OF HOLLOW TITANIUM STRUCTURE MATERIAL

摘要

A technical field for a joint section, used for on-site joining of titanium structure materials when titanium structure materials (including titanium alloy structure materials, the same in the followings) are used for columns and beams of a building. A stress (load) on a titanium structure material used for a building column and beam is dividedly burdened by a bolt joint and a welding joint so as to downsize a bolt joint structure to an inconspicuous level on one side, and to overcome a difficulty in weld-joining a titanium structure material on the other side to thereby ensure stable quality and strength, whereby a joint section for a hollow titanium structure material, high in quality and joint strength reliability, can be provided.
