Embodiment 1

[0050] Such as Figure 1-12 As shown, in the embodiment of the present invention, a special-shaped column of an internally supported steel structure includes a central column 1, a side column 6 and a corner column 12, and a plurality of central columns 1 are connected around the central column 1, and multiple columns are arranged at the edge of the building. A side column 6, between the side column 6 and the side column 6 is provided with a corner column 12 for connecting the middle column 1 and the side column 6, between the middle column and the middle column, between the center column and the side column and the middle column side column and the side column. The corner columns are connected by H-shaped steel beams and reinforced by scissors support. The center column support assembly is provided in the center column 1, the side column support assembly is provided in the side column 6, and the corner column support assembly is provided in the corner column 12.

Embodiment 2

[0053] Such as Figure 1-12 As shown, in the embodiment of the present invention, the manufacturing method of the special-shaped column of the inner support steel structure, the steps are as follows:

[0054] S1. The production and assembly of each column in the special-shaped column of the inner support steel structure;

[0055] S2, the production and assembly of the central column 1;

[0056] S201. First, according to the cross column process method and manufacturing steps, the inner support web 4 of the material column and the center column flange plate 3 are assembled and welded to form a cross column member;

[0057] S202. Cutting the center column flange restraint plate 2 and the center column inner horizontal support stiffener plate 5, weld the center column inner horizontal support stiffener plate 5 at the corresponding position in the cross column member, and fill the cavity of the center column 1 with light weight After the concrete 7 is completely dried, the cente...

Embodiment 3

[0071] Such as Figure 1-12 As shown, in the embodiment of the present invention, the manufacturing method of the special-shaped column with eccentric inner support steel structure, the steps are as follows:

[0072] S1. The production and assembly of each column in the special-shaped column of eccentric inner support steel structure;

Abstract

The invention discloses a manufacturing method of an inner support steel structure special-shaped column, belongs to the technical field of steel structure engineering, and well solves the problem of poorer torsional deformation resistance of an existing steel structure column at a high axial compression ratio by utilizing a self complete inner support and outer sealed structure form. The manufacturing method is technically characterized by comprising the following manufacturing steps that each column body in the inner support steel structure special-shaped column is assembled; the inner support steel structure special-shaped column comprises a middle column, side columns and corner columns; and a plurality of side columns are horizontally arranged in edge positions of a building. A building structure using the inner support steel structure special-shaped column in the embodiment of the invention realizes more reasonable stress and force transmission; the safety, stability and reliability of the whole building can be guaranteed to the maximum extent; the damage to the building under various load and natural disaster conditions is reduced and eliminated; the life and property safety of people is guaranteed; and the method is more suitable for assembled high-rise and super high-rise civil and public buildings.

Description

technical field [0001] The invention relates to the technical field of steel structure engineering, in particular to a method for manufacturing special-shaped columns of internally supported steel structures. Background technique [0002] At present, the commonly used cross-shaped steel structure column has no weak axis, and its flexural bearing capacity, ductility and seismic bearing capacity are better; but compared with the circular tube and box-shaped steel structure column, its torsional performance is poor, especially in high axial compression Deformation is faster than the next. [0003] Therefore, the cross-shaped steel structure column generally needs to be combined with reinforced concrete to have better mechanical performance (improving the strength of the outsourcing concrete of the cross-shaped steel structure column, increasing the reinforcement ratio of the stirrup, and improving the strength of the stirrup can all make the cross-shaped steel structure column ...
