MANUFACTURE OF JUNCTION PART OF BEAM MEMBER FOR BUILDING STRUCTURE, AND BEAM MEMBER FOR BUILDING STRUCTURE PROVIDED THEREBY

摘要

PROBLEM TO BE SOLVED: To provide a method for fabricating a novel junction part which is free of dust and noise generation and a junction part fabricated according to the method. SOLUTION: A bolt fastening hole 7 is furnished in a junction part of a beam member 1 for architectural structure, and the joining surface in the periphery of this hole 7 is provided with a plurality of ruling lines 9 by the laser processing so that the friction factor of the joining surface is increased. Also a bolt fastening hole 7 is furnished in a junction part of a beam member 1 for architectural structure, and the joining surface in the periphery of this hole 7 is provided with a plurality of ruling lines 9 by the laser processing so that the friction factor of the joining surface is increased.
