Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] like Figure 1-6 Shown: a corrugated web cross-section steel column, including corrugated steel web 2 and flat steel plate flange 1, which is welded by one piece of corrugated steel web H-shaped steel and two pieces of corrugated steel web T-shaped steel or four pieces The corrugated steel web is welded by T-shaped steel or three pieces of corrugated steel web 2 and four pieces of flat steel plate flange 1 are welded and combined. The connection point of corrugated steel web 2 and flat steel plate flange 1 is located At the midpoint of the width, the form of the corrugated steel web 2 is curved, broken line or trapezoidal. The various forms of the corrugated steel web 2 require at least one wave width.

[0026] It should be pointed out that those skilled in the art can make some improvements and modifications without departing from the...

Abstract

The invention discloses a corrugated web steel column with a cross-shaped section. The corrugated web steel column comprises corrugated steel webs and plain plate flanges and is formed by welding an H-shaped corrugated web steel and two T-shaped corrugated web steel or welding four T-shaped corrugated web steel or welding three corrugated steel webs and four plain plate flanges, wherein the connection points of the corrugated steel webs and the plain plate flanges are in the middle of the width of the plain plate flanges, and the corrugated steel webs are curved, folded or trapezoidal. The steel column is reasonable in section composition, has good mechanical properties, high bearing capacity, good ductility, excellent anti-seismic property and simple structure, is convenient and fast to produce and process, saves steel and is low in cost.

Description

technical field [0001] The invention relates to a novel structure in construction engineering, in particular to a corrugated web cross-section steel column. Background technique [0002] The multi-high-rise steel structure is becoming more and more prominent in my country's modernization construction, and is more and more favored by people. In recent years, it has been highly valued by scholars and engineers at home and abroad, and has been widely used. [0003] In the actual project of multi-story steel structure, especially in the transitional layer project connecting the lower reinforced concrete basement and the upper steel structure, the traditional flat web cross-section steel column is usually used, and its cross-section size is usually large, especially is the web dimension. In order to ensure the local stability of the web and meet the web height-to-thickness ratio limit specified in the "Code for Design of Steel Structures", the web thickness is usually increased,...
