Multi-branch irregular box-type column and machining method

Abstract

The invention relates to a multi-branch irregular box-type column. The multi-branch irregular box-type column comprises a box-type body and a branch structure, wherein the box-type body is provided with multiple sections, each section of the box-type body is vertically arranged and is welded and fixed to the irregular branch structure, a support column is adopted to obliquely support the box-typebody, and the branch structure is obliquely intersected with the axis of the box-type body; and the branch structure comprises a flange, the flange is welded to the branch structure, and the multiplessections of the box-type body are welded to the branch structure and then sequentially connected to form the box-type column. The invention further provides a machining method of the multi-branch irregular box-type column. The machining method has the beneficial effects that the sectional automatic welding mode is adopted for machining, the machining method is simple, the time consumption is short, the machining cost and the labor cost are effectively saved, and the assembling quality of the box-type column is improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a multi-branch irregular box-shaped column and a processing method thereof. Background technique [0002] With the development of steel structure buildings, there are more and more steel structure projects with complex shapes and structures. The column nodes of this project are also particularly complicated. The column body is generally box-shaped, and the nodes are multi-branch structures, and the branch structure type There are many, including box beams and box supports, H-beams and H-supports, and buckling-restrained supports. The axes are mostly oblique axes, the branch structures intersect obliquely with the box-shaped columns, and the branch structures intersect with each other, with irregular shapes. The steel columns are thick plate box structures, and the branch structures are also thick plate structures. Such complex nodes are extremely difficult to proce...

Such complex nodes are extremely difficult to process

[0003] The traditional processing method is, after the butt welding of the box column box is completed, the box column is placed parallel to the ground, the branch structure of the first surface is assembled, and then rotated 90 degrees, the branch structure of the second surface is assembled, and then Rotate 90 degrees to assemble the branch structure of the third surface. When assembling the branch structure of the third surface, the branch structure of the first surface is under the box-shaped column, and a tire frame needs to be erected to lift the branch structure of the first surface In the same way, when assembling the branch structure on the fourth side, the branch structure on the second side needs to be raised with a tire frame, and the branch structure is not parallel to the ground during assembly, and the assembly accuracy depends on the space between the branch structure port and the box-shaped column. Dimensional control, poor assembly accuracy

When the branch structure is welded, because the groove of the weld seam is opened on the branch structure, manual welding can only be used for welding, and the welding workload is large and the efficiency is low
