METHOD FOR JOINING MEMBER, JOIN STRUCTURE, CARGO TRANSPORT VEHICLE, AND CARGO TRANSPORT CONTAINER

摘要

PROBLEM TO BE SOLVED: To obtain high dimensional precision and secure flatness between members.SOLUTION: A joining method for joining first and second members each having plate parts formed on both sides and formed in a hollow planar shape by connecting and welding them along a plane direction includes: an abutment step for abutting an end section (tip of a ridge 37) of the second member (adjacent floor section 30) to the bottom of a concave section (concave groove 38) formed at the end of the first member (floor section 30); and a welding step for welding the plate sections of one of the both surfaces, and then welding the plate sections of the other surface. One of the plate sections is a thin plate section (bottom plate section 34), and the other plate section is a thick plate section (top plate section 33) thicker than the thin plate section (bottom plate section 34), and preferably in the welding step, after welding the thin plate sections (bottom plate sections 34), the thick plate sections (top plate sections 33) are welded.
