STEEL FRAME MEMBER MANUFACTURING METHOD
PROBLEM TO BE SOLVED: To provide a steel frame member manufacturing method that can reduce manufacturing costs by decreasing the man-hours needed to form a plurality of through holes and to secure strength of a web.SOLUTION: A first intermediate body 13 and a second intermediate body 14 are manufactured by cutting a web 11 of blank shaped steel 10 along a line 12 extending in a longer direction L of the web 11 of the blank shaped steel 10. The line 12 for cutting the line 11 is a line which passes a first position Pbetween a center position Win a width direction Wof the web 11 and a lower flange 3, and a second position Pbetween the center position WC and an upper flange 4. While first and second cut pieces 111, 112 are shifted in a width direction Wof the lower flange 3 and upper flange 4, a tip of the first cut piece 111 is joined to the upper flange 4 and a tip of the second cut piece 112 is joined to the lower flange 3 with cut parts 21b, 22b of the first and second cut pieces 111, 112 put one over the other.SELECTED DRAWING: Figure 3
【課題】複数の貫通孔の形成とウェブの強度確保とに要する工数を削減し、製造コストを低減できる鉄骨部材製作方法を提供する。【解決手段】素材形鋼１０のウェブ１１の長手方向Ｌに延びる線１２に沿って素材形鋼１０のウェブ１１を切断し、第１中間体１３及び第２中間体１４を製作する。ウェブ１１を切断する線１２は、ウェブ１１の幅方向ＷＷの中央位置ＷＣと下フランジ３との間の第１位置Ｐ１と、中央位置ＷＣと上フランジ４との間の第２位置Ｐ２とをそれぞれ複数回通る線である。第１及び第２切断片１１１，１１２を下フランジ３及び上フランジ４の幅方向ＷＦにずらしつつ、第１及び第２切断片１１１，１１２の切欠部分２１ｂ，２２ｂを互いに重ねた状態で、第１切断片１１１の先端を上フランジ４に接合するとともに、第２切断片１１２の先端を下フランジ３に接合する。【選択図】図３
