Problems solved by technology

[0003] And with the continuous change of architectural design and shape, in high-rise buildings, the steel structure of the ground part presents a variety of shapes, no longer a single box-shaped structure, but a cylindrical shape, and if the underground part adopts the same shape as Steel columns with the same section above the ground will greatly waste the amount of steel used

Embodiment

[0033] Such as figure 1 A cross-section steel column with variable cross-section shown includes: an upper circular column 1, a middle conical column 2, a lower circular cross column 3 and a steel corbel 4; the overall shape of the upper circular column 1 is A cylindrical shape; the conical column 2 is a truncated cone; the outer part of the circular cross column is cylindrical as a whole.

[0034] The connection relationship between the above-mentioned main components is: the top of the conical column 2 is assembled and welded together with the lower end of the upper cylindrical column 1, and the bottom end of the conical column 2 is assembled and welded with the upper end of the circular cross column 3; The steel corbel 4 is assembled and welded on the outer surface of the upper circular pipe column 1 .

[0035] In the present embodiment, the upper cylindrical pipe column 1 is divided into an upper section 11, a middle section 12 and a lower section 13; the lower section 13...

Abstract

The invention discloses a section-variable crossed circular tube switching steel column. The section-variable crossed circular tube switching steel column comprises an upper circular tube column, a middle conical column, a lower circular crossed column and a steel bracket, wherein the top end of the conical column is welded to the upper circular tube column and the bottom end of the conical column is welded to the circular crossed column; and the steel bracket is welded to the outer surface of the upper circular tube column. The invention also discloses a manufacturing method for the section-variable crossed circular tube switching steel column. By the invention, switching of steel column structural styles on underground and aboveground parts of high buildings is realized; a large quantity of steel materials are saved for the steel structures on the underground parts; and aims of minimizing the section and maximizing the bearing capacity are fulfilled.

Description

technical field [0001] The invention belongs to a composite steel column and a manufacturing method thereof, in particular to a composite column composed of a cross-shaped steel column, a circular tube column and a tapered column and a manufacturing method thereof. Background technique [0002] With the rapid development of China's economy, high-rise buildings have sprung up all over the country. As the buildings are getting taller and larger, considering the structural strength and safety performance, the structural form It is also shifted from reinforced concrete structure to steel reinforced concrete structure or steel structure. Reinforced concrete columns in high-rise buildings can no longer meet the requirements of high-rise buildings and have been replaced by concrete steel columns. In high-rise buildings, the force on the underground part is relatively small. If the cross-section of the steel column is designed from the bottom to the top, the material will be wasted...
