CONNECTION STRUCTURE OF SQUARE STEEL PIPE COLUMN AND WIDE FLANGE-SHAPED STEEL BEAM

摘要

PROBLEM TO BE SOLVED: To increase the connection strength, by chamfering the front end of the extended part stretched outward and integrally formed at the protruded part of a diaphragm and welding it with the flange end of the wide flange- shaped steel beam butted against each other. ;SOLUTION: The protruded part 21 at the periphery of the upper side diaphragm 2 of a square steel pipe column 1 is integrally formed with the extended part 22 stretched outward from the protruded part 21. And the protruded part 31 stretched at the periphery of the lower side diaphragm 3 of the square steel pipe column 1 is integrally formed with the extended part 32 stretched outward. The front end of the extended parts 22, 32 is cut diagonally to form a chamfered end 23, 33 which is sharpened as it goes to the end, respectively. Rib plates 4 with bolt holes 43 are welded and fixed between the extended parts 22, 32. And further, the rib plates 4 and the web of the flange of the wide flange-shaped steel beam are connected with splice plates, bolts, and nuts and the ends of flange are arranged to butt the extended parts 22, 23 and welded to fix them.;COPYRIGHT: (C)1997,JPO
