Fabricated steel structure node

The invention discloses a fabricated steel structure node. The fabricated steel structure node comprises a node short column and box type columns, wherein node flanges are connected to the node short column, a column flange is connected to each box type column, a kidney-shaped hole is formed in each node flange, a bolt is arranged on each node flange, and a rod part of each bolt is arranged in the corresponding kidney-shaped hole in a sliding mode; and a nut is in threaded connection to the rod part of each bolt, each nut is located on the side, away from the head of the corresponding bolt, of the corresponding node flange, and a connecting groove allowing the rod part of the corresponding bolt to stretch into is formed in the side wall of each column flange. The fabricated steel structure node has the effect of improving the safety performance of the steel structure node during mounting. 本申请公开了一种装配式钢结构节点，其包括节点短柱以及箱型柱，所述节点短柱上连接有节点法兰，所述箱型柱上连接有柱法兰，所述节点法兰上开设有腰型孔，所述节点法兰上设置有螺栓，所述螺栓的杆部滑动设置在腰型孔中，所述螺栓的杆部上螺纹连接有螺母，所述螺母
