HOT-ROLLED ANGLE STEEL, SQUARE STEEL TUBE FOR BEAM-COLUMN JOINT CORE, BEAM-COLUMN JOINT CORE, AND BEAM-COLUMN JOINT STRUCTURE

摘要

PROBLEM TO BE SOLVED: To easily manufacture a square steel tube for a non-diaphragm type beam-column joint core by steel double-welding without use of channel steel.;SOLUTION: Hot-rolled angle steel 11 is used to manufacture the square steel tube 1 for the non-diaphragm type beam-column joint core 1 serving as a beam-column joint for being joined to an H-shaped steel beam, by angle steel double-welding. One flange 11b is shorter by the plate thickness (t) of the angle steel than the other flange 11a. A leading end of the short flange 11b has a single bevel face 11c (or a K bevel face). The two pieces of angle steel 11 are temporarily assembled in a square shape, and the leading ends of the flanges butting against each other in a temporarily-assembled state are welded and joined to each other, so that the square steel tube 1 for the square beam-column joint core 1' can be obtained. The square steel tube for the square beam-column joint core can be manufactured by the double-welding using the hot-rolled angle steel 11 as-is.;COPYRIGHT: (C)2010,JPO&INPIT
