JOINT STRUCTURE OF SQUARE STEEL PIPE COLUMN
To form a square steel pipe column by axially butting an upper column member and a lower column member separated from each other and joining them without depending on welding, and to prevent loss of compressive force due to contact between corner members while generating compressive force acting on a corner member arranged inside an outer ring most effectively on the column.SOLUTION: Recessed grooves 22, 32 are formed in the circumferential direction at least in corner parts 21, 31 at positions spaced apart from the abutment surfaces 2a, 3a of an upper column member 2 and a lower column member 3, respectively; a corner members 4 in contact with the outer peripheral surfaces of the upper column member 2 and the lower column member 3 are arranged at the respective corner parts 21, 31 of the upper column member 2 and the lower column member 3 which are butted against each other, while axially straddling both recessed grooves 22, 32 of the upper column member 2 and the lower column member 3; an outer ring 5 continued in the circumferential direction of the upper column member 2 and the lower column member 3 and capable of bearing tensile force is arranged on the outer peripheral side of all the corner members 4.SELECTED DRAWING: Figure 1
【課題】互いに分離している上柱部材と下柱部材を軸方向に突き合わせ、溶接に依らずに接合して角形鋼管柱を構成する上で、外リングの内側に配置されるコーナー材に作用する圧縮力を最も有効に柱に生じさせながら、コーナー材同士の接触による圧縮力の損失を生じさせない。【解決手段】上柱部材２と下柱部材３の突き合わせ面２ａ、３ａからそれぞれ距離を置いた位置の、少なくとも各隅角部２１、３１に凹溝２２、３２を周方向に形成し、突き合わせられた上柱部材２と下柱部材３の各隅角部２１、３１に、上柱部材２と下柱部材３の両凹溝２２、３２に軸方向に跨りながら、上柱部材２と下柱部材３の外周面に接触するコーナー材４を配置し、全コーナー材４の外周側に、上柱部材２と下柱部材３の周方向に連続し、引張力を負担可能な外リング５を配置する。【選択図】図１
