Embodiment

[0039] The steel structure steel column of Beijing Yintai Center adopts box-shaped column. The basic parameters of the box-shaped column: the cross-sectional size of the box-shaped column is 700*700, the thickness of the wing plate 2 and web plate 1 is 40mm, the thickness of the partition is 32mm, the length of the box-shaped column is 12m, There are three nodes in the full length of the column, and each node is equipped with two partitions 3. Since manual welding cannot enter the column to complete the welding of the partitions 3, electroslag welding is used to complete the welding of the partitions 3 and the flange 2. The electroslag welding seam is set between the partition plate 3 and the wing plate 2, and the welding process steps of the overall box-shaped column are as follows:

[0040] a) Blanking: According to the drawing size of the box-shaped column, use a CNC cutting machine to blank, among which, there are two pieces of web 2, two pieces of wing plate 2 and six piec...

Abstract

The invention discloses a method for welding a box-shaped column, which comprises a process for welding the box-shaped column and a method for welding a weld joint between a partition plate and a wing plate by electric slag welding. The box-shaped column comprises a web plate, the wing plate and the partition plate. The weld joint between the partition plate and the wing plate of the box-shaped column is welded by the electric slag welding method, and the overall welding process of the box-shaped column is analyzed and optimized based on the method. Thus, the process route is simple and accurate; and the method has the advantages of reducing manufacturing difficulty, improving processing precision, improving production efficiency and improving the quality of members.

Description

Background technique [0001] Box columns have been widely used as structural columns in high-rise buildings. In steel structures, box columns need to be connected with steel beams on each floor. The area where box columns are connected to steel beams is a node. The structural stability of the joints and the good stress state at the joints. The steel structure design code GB50017-2003 stipulates that transverse partitions should be installed at the joints inside the box columns, and the centerline of the transverse partitions should be aligned with the centerline of the beam flange. The penetration "T" type butt weld is used to connect the column flange, and when arc welding cannot be performed, electroslag welding shall be used for welding. The existing problem is that adopting different welding processes of box-shaped columns and different welding orders of partitions and flanges or partitions and webs will directly affect the processing accuracy, production efficiency and qua...
