The invention discloses a fabricated box-shaped structure and a connecting joint thereof. The fabricated box-shaped structure comprises a box-shaped structure body, an outer flange, an inner flange and a corrugated web. According to the fabricated box-shaped structure, the outer flange is not provided with a protruding edge of a flat flange plate like H steel, and edge fibers cannot be plasticized when the outer flange is subjected to normal stress; meanwhile, through a cold-bending forming piece and due to the cold-bending strengthening effect, the bearing capacity of material of the outer flange is improved; a full-fabricated structure is achieved, and a traditional welding beam column structure is replaced; in consideration of the stability problem of the corrugated web, planes on the two sides of the corrugated web are restrained; connection is carried out through a bolt instead of a self-tapping screw, and the situations that the hole diameter of a connected piece is larger than the outer diameter of the bolt, the connecting piece can generate relative slippage to dissipate a part of energy when large external force is borne, and the external force cannot generate shear damage to the bolt in the first time are fully considered; the inner flange and the outer flange are connected into a whole in the mode that the two ends of the inner flange and the outer flange are welded to end plates, and the middle parts of the inner flange and the outer flange are perforated and spot-welded.
本发明公开了一种装配式箱形结构及其连接节点，包括箱形结构、外翼缘、内翼缘、波纹腹板。本发明的外翼缘没有像H钢的那种平翼缘板的突出边缘，在受到正应力时不会产生边缘纤维的塑化，同时外翼缘是通过冷弯成型件，因冷弯强化作用，提高了材料的承载能力。本发明实现了全装配式结构，代替传统焊接梁柱结构。考虑到波形腹板的稳定性问题，对波纹腹板的两侧平面均进行了约束。通过螺栓而不是自攻螺钉进行连接，充分考虑到被连接件的孔径比螺栓外径大，在受到较大外力时，连接件会产生相对滑移而耗散掉一部分能量，外力不会在第一时间对螺栓产生剪切破坏。内、外翼缘之间的连接通过两端与端板焊接，中间部位开孔点焊的方式将内外翼缘板连成一体。
