Steel column with cross-shaped connecting section connected with round pipe and working method thereof

Abstract

The invention discloses a manufacturing method of a steel column with a cross-shaped connecting section connected with a round pipe. The manufacturing method comprises the steps that firstly, self gathering of a cross-shaped web plate is conducted at first; an upper opening annular plate is installed at an upper opening of a convex part of the cross-shaped web plate and the upper opening of a first convex part; a set of inner partition plates are arranged at the intersection of a first web plate and a second web plate, and one edge of each inner partition plate is fixed; square-connected-circular joint plates are subjected to splicing and assembling welding in a four-half splicing mode; assembling welding is conducted on a lower opening annular plate; assembling welding is conducted on the inner partition plates at the intersection of the cross-shaped web plates at the lower part of the lower opening annular plate; assembling welding is conducted on a box-shaped column; the other two edges of each inner partition plate are welded and fixed; and assembling welding is conducted on a round pipe column, a joint plate and stiffening plates are installed, and finally a lower-section joint and the box-shaped column at the lower portion of the cross-shaped web plate are subjected to assembling welding. According to the manufacturing method of the steel column with the cross-shaped connecting section connected with the round pipe, the structure is optimized, the construction process is optimized, the round pipe column, the cross-shaped connecting section and the lower-section joint are correspondingly folded, and the machining efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of steel structures, and in particular relates to a cross-rotating circular tubular steel column and a working method thereof. Background technique [0002] With the rapid development of social economy, all walks of life are constantly developing, and so is the construction industry. Steel structure buildings are favored by major venues and centers because of their short construction period, freedom from climate constraints, and their ability to meet the architectural needs of various special structures. [0003] Support nodes are necessary support components in steel structure buildings. However, many of the existing support nodes are hollow support columns, which have low support and bearing capacity, and their structural stability needs to be improved; [0004] And even if the structure of some supporting parts is relatively complicated, the manufacturing method is relatively cumbersome, and most of them...

Problems solved by technology

[0003] Support nodes are necessary support components in steel structure buildings. However, many of the existing support nodes are hollow support columns, which have low support and bearing capacity, and their structural stability needs to be improved;

[0004] And even if the structure of some supporting parts is relatively complicated, the manufacturing method is relatively cumbersome, and most of them are directly processed in order for each part during processing, which requires a lot of time and manpower, which affects its normal construction progress. ,

[0005] And due to the characteristics of its structure, one end of the square joint circle is square, and the other end is arc-shaped, especially at the square end, fracturing is prone to occur at the 90° rolling angle. This part needs to be pre-treated to avoid cracking Therefore, the processing of special-shaped gusset plates is difficult, and therefore the existing manufacturing methods of support nodes still need to be improved
