Beam-to-column joints intersect method of building steel structure

摘要

PROBLEM TO BE SOLVED: To solve problems that a column-beam joint part has a complicated structure, there are dangers of the occurrence of a stress concentration and distortion, increase of the manufacturing man-hours, and the like in the column-beam joint part of a building steel frame heretofore manufactured by jointing a column and a beam by welding to a square mortar block manufactured by combining short steel pipes with diaphragms.;SOLUTION: A rectangular steel pipe column and H-shape steel beams are passed through each other, or using two parallel steel plates as a substitute beam instead of the H-shape steel beam, the rectangular steel pipe column and the beams are passed through each other to intersect the beams inside the column. A backing strip is supplied from the outer surface, and taking large welding throat depth, the column and the beam are directly welded and jointed. The die including a diaphragm of small assembly is thereby omitted, and intermediate assembly of jointing the square mortar block and beams can be omitted to sharply reduce applied material and the amount of welding the column and further to reduce the occurrence of stress concentration and distortion and the embrittlement of a thermally affected part.;COPYRIGHT: (C)2004,JPO
