JOINT STRUCTURE OF SQUARE STEEL PIPE COLUMN AND H-SHAPED STEEL BEAM
To provide a joint structure between a square steel pipe column and an H-shaped steel beam, in which the strength of the outer diaphragm against the tensile force in the direction outside the steel pipe column surface is not reduced and that does not hinder the soundness inspection of the beam flange-outer diaphragm welding by ultrasonic flaw detection.SOLUTION: A joining structure 1 of a square steel pipe column and an H-shaped steel beam according to the present invention joins a square steel pipe column 3 and an H-shaped steel beam 7 via an outer diaphragm 9, and the outer diaphragm 9 is formed by abutting the ends of two L-shaped steel pieces 11 having the same shape into a rectangular ring shape, and the inner peripheral surface of the rectangular ring is welded to the skin plate 5 of the square steel pipe column 3, two joint surfaces 13 between the L-shaped steel pieces 11 are located at the corners of the square steel pipe column 3, the angle formed by the extension surface of each orthogonal skin plate 5a, b, c, d of the rectangular steel pipe column 3 and the joining surface 13 is set to be 25 degrees or more and 65 degrees or less, and the joining surface 13 is joined by fillet welding, and the length of the welded portion is 10% or more of the projected dimension of the outer diaphragm 9.SELECTED DRAWING: Figure 1
【課題】鋼管柱面外方向の引張力に対する外ダイアフラムの耐力が低減することなく、また梁フランジ−外ダイアフラム溶接の健全性検証を超音波探傷検査で行うことに支障が生ずることのない角形鋼管柱とＨ形鋼梁の接合構造を提供する。【解決手段】本発明に係る角形鋼管柱とＨ形鋼梁の接合構造１は、角形鋼管柱３とＨ形鋼梁７とを外ダイアフラム９を介して接合するものであって、外ダイアフラム９は、同一形状の２枚のＬ字形鋼片１１の端部を突き合わせて矩形リング状にして、該矩形リングの内周面が角形鋼管柱３のスキンプレート５に溶接接合されてなり、Ｌ字形鋼片１１同士の２か所の接合面１３が角形鋼管柱３の角部に位置し、角形鋼管柱３の直交する各スキンプレート５ａ、ｂ、ｃ、ｄの延長面と接合面１３とが成す角度がいずれも２５度以上６５度以下となるように設定され、かつ接合面１３が隅肉溶接によって接合されて、その溶接部の長さが外ダイアフラム９の出寸法の１０％増し以上となっていることを特徴とするものである。【選択図】 図１
