Problems solved by technology

The support column of the whole plant has the characteristics of small load but relatively long
When steel is used as the main material for design, the strength requirements of the cantilever steel support column can often be met with a small cross-section, but it takes a lot of money to meet the stability requirements of the component, especially the out-of-plane stability of the component sexual demands

Embodiment 1

[0013] Embodiment 1 of the present invention: such as figure 1 As shown, the steel support column for a factory building of the present invention includes a web 1 of the steel support column. Three or more braces 2 are welded on both sides of the web 1, and the braces 2 on both sides are symmetrical with the web 1. And perpendicular to the plane where the web 1 is located; a pre-stressed member 3 is connected between the struts 2 located at the uppermost end and the lowermost end on each side of the web 1, that is, the two ends of the pre-stressed member 3 are anchored at the most by anchors. On the upper and lower struts 2.

[0014] A triangular steel plate 4 is fixed on the inner side of the uppermost and lowermost struts 2 to make the anchoring of the prestressed member 3 more stable.

[0015] The length of the struts 2 located between the uppermost end and the lowermost end is shortened from the middle to the two ends in turn, and their ends are all pressed against the prestre...

Abstract

The invention discloses a steel bracket column used for a factory. The two sides of a web plate of the steel bracket column are respectively fixedly provided with a row of brace rods (2), the brace rods (2) at the two sides of the web plate are symmetrical to the web plate (1) and are vertical to the plane on which the web plate (1) is located; and prestress construction members (3) are connected between the uppermost brace rod (2) and the bottommost brace rod (2) at each side of the web plate (1). Compared with the prior art, a certain amount of brace rods are fixed on the web plate of the steel bracket column, and prestress is applied to the prestress construction members, thus the effect of reducing out-plane calculated length of the construction member, and finally the out-plane stability of the construction member is guaranteed, thus the construction member is required to meet the in-plane stability only. Besides, the structural design in the invention is reasonable, not only is the structure simple, but also the design section is greatly reduced, and the economic cost is saved.

Description

Technical field [0001] The invention relates to a steel support column, in particular to a steel support column used in a large-scale workshop. Background technique [0002] During the construction of modern industrial plants, the application of steel is more and more extensive. In order to speed up the construction progress, the whole plant's brackets are slowly using steel as the main material. The support columns of the whole plant have the characteristics of small load-bearing but relatively long. When steel is used as the main material for the design, a small cross-section can often meet the strength requirements of the cantilever steel support column, but it will cost a lot to meet the stability requirements of the component, especially the out-of-plane stability of the component Sexual requirements. Because the radius of gyration of our commonly used component sections in the plane is generally 2 to 3 times the out-of-plane, and the calculated length of the support colu...
