The invention discloses a torsion crossed welding intersected node of a steel component with the rectangular cross section, which comprises a vertical joint (1) and two transverse joints (3), wherein each transverse joint (3) consists of a first block body (3-1) and a second block body (3-2), the end surfaces (3-3) of the first block bodies (3-1) of the two transverse joints (3) are aligned and welded with the side surface of the vertical joint (1), the end surfaces (3-4) of the second block bodies (3-2) of the two transverse joints (3) are aligned and welded with the end surface of a transverse steel component (4), both ends of the vertical joint (1) are respectively connected with two vertical steel components (2), and the end surfaces (3-3) of the first block bodies (3-1) and the end surfaces (3-4) of the second block bodies (3-2) form a certain angle or are staggered. The invention adapts to a structure that the bidirectional steel component wing edges are out of plane and unparallel on the basis of less increase on manufacture cost and self gravity of the node and no change of the fixed connection characteristics of the intersected node, and has the advantages of simple process and easy mastering.
