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.

Embodiment 1

[0036] Such as figure 1 , 2 , 3 and 4, a rectangular cross-section steel member torsionally meets and welds intersecting joints, including a longitudinal joint 1 and two transverse joints 3, the transverse joints 3 are composed of folded plates and flat plates, which can be structurally It is divided into a first block 3-1 and a second block 3-2. The folded plate means that the upper surfaces of the first block 3-1 and the second block 3-2 are formed by a folded plate. The flat plate means that the sides of the first block 3-1 and the second block 3-2 are respectively two flat plates. The plane projections of the first block 3-1 and the second block 3-2 are triangular or quadrilateral, the end face 3-3 of the first block 3-1 is welded in alignment with the side of the longitudinal joint 1, and the second block 3-2 The end face 3-4 of the first block is aligned and welded with the end face of the transverse steel member 4; the two ends of the longitudinal joint 1 are connect...

Embodiment 2

[0043] Rectangular cross-section steel members are twisted, intersected and welded intersecting joints. The transverse steel member 4 is H-shaped steel, and the longitudinal steel member 1 is square steel pipe. The folded plate is the longitudinal joint of the node.

[0044] According to the method of the present invention, a series of embodiments can also be developed. For example, the transverse steel member 4 can adopt rectangular steel pipes, square steel pipes or steel members with other cross-sectional forms according to design requirements. The longitudinal steel member 2 can also adopt rectangular steel pipes, square steel pipes or other cross-sectional steel members according to design requirements. The longitudinal steel member 2 and the transverse steel member 4 do not necessarily have the same width, nor do they necessarily need to have the same section height. The components that meet together do not have to be bidirectional, but can be in multiple directions.

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...
