Torsion crossed welding intersected node of steel component with rectangular cross section

Abstract

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.

Description

technical field [0001] The invention relates to a connection node of a space steel structure, in particular to a welded intersecting node where steel members with rectangular cross-sections are twisted and intersected. Background technique [0002] In steel buildings, steel members meet to form joints. Nodes play a role in coordinating the force and deformation of components, which is of great significance to ensure the safety of structures. In modern space steel structure engineering, joints formed by direct intersecting welding of steel members are often used because of their simple appearance and clear force transmission. [0003] The cross-section forms of steel members often used in steel structure buildings are mostly closed or open formed by steel plates, and the outer contour of the cross-section is a rectangular (including square, H-shaped, etc.) cross-section. [0004] In buildings with regular shapes, it is not difficult to directly intersect rectangular cross-s...

AI Technical Summary

Problems solved by technology

Using this method, the disconnected steel members become hinged at the joints, which reduces the stiffness of the structure, and the structure deforms greatly under the load, and if the deformation is to be controlled, the amount of steel used in the structure will be increased.
