JOINT STRUCTURE OF RECTANGULAR STEEL PIPE COLUMN
To provide a joint structure preventing drop in strength by changing thickness on a column base side and a column head side at a rational place of a steel pipe column.SOLUTION: A joint structure of a steel pipe column includes a first diaphragm disposed on one end of a first steel pipe column, a flange connected to the first diaphragm so that a flange face is disposed in substantially parallel with a material axis direction of the first steel pipe column, a second diaphragm disposed on one end of a second steel pipe column, a flange connected to the second diaphragm so that a flange face is disposed in substantially parallel with a material axis of the second steel pipe column, and a doubling plate. The column diameter of the first steel pipe column is larger than the column diameter of the second steel pipe column. The second steel pipe column is disposed on the first steel pipe column so that the first diaphragm and the second diaphragm face each other. The first steel pipe column is connected to a first beam. The second steel pipe column is connected to a second beam. The flange connected to the first diaphragm and the flange connected to the second diaphragm have a bolt joint part at which these flanges are connected with bolts through the doubling plate. The bolt joint part is disposed between the first beam and the second beam.SELECTED DRAWING: Figure 1
【課題】鋼管柱の合理的な箇所で柱脚側と柱頭側の太さを変更し、強度を低下させない継手構造を提供する。【解決手段】鋼管柱の継手構造は、第１の鋼管柱の一端に設けられた第１のダイアフラムと、第１の鋼管柱の材軸方向と略平行にフランジ面が配置され、第１のダイアフラムと接合されたフランジと、第２の鋼管柱の一端に設けられた第２のダイアフラムと、第２の鋼管柱の材軸方向と略平行にフランジ面が配置され、第２のダイアフラムと接合されたフランジと、添え板とを含む。第１の鋼管柱の柱径が第２の鋼管柱の柱径より大きく、第１のダイアフラムと第２のダイアフラムとが対向するように、第１の鋼管柱の上に第２の鋼管柱が配置され、第１の鋼管柱が第１の梁に接合され、第２の鋼管柱が第２の梁に接合され、第１のダイアフラムに接合されたフランジと第２のダイアフラムに接合されたフランジとが、添え板を介してボルト接合されたボルト接合部を有し、ボルト接合部が、第１の梁と第２の梁との間に設けられている。【選択図】図１
