Manufacturing process of box type combination column

Abstract

The invention discloses a manufacturing process of a box type combination column, and relates to the technical field manufacturing of combination columns. The process includes the following steps of S1, pre-combining, wherein an arbitrary box type column is erected on a bed-jig, and the bed-jig or another box type column is moved, so that edges of the two box type columns are adjacent; S2, pre-welding, wherein two side plates of angle iron are sequentially welded and connected to two side walls of an angle groove through a spot welding mode, and therefore the combination column is formed; S3,welding supporting, wherein the combination column is moved out of the bed-jig, supporting steel is welded to the included-angle position between the two box type columns through turning, and the twoends of the supporting steel are welded and connected to the two box type columns correspondingly; and S4, welding operation, wherein the combination column is turned, the adjacent edges of the two box type columns are welded and connected from the outside, and the joints of the angle iron and the angle groove are welded and connected from the outside. The manufacturing process has the advantagesthat the situations of deformation of welding points and dislocation between the two box type columns in turning of the L-shaped combination column are reduced, and the production quality of the L-shaped combination column can be easily ensured.

Description

technical field [0001] The invention relates to the technical field of manufacturing composite columns, in particular to a manufacturing process of a box-shaped composite column. Background technique [0002] At present, in the current construction process, a large number of steel structure projects are often covered, and in the construction process of these steel structure projects, the box-type composite column has achieved good application results because it can meet the structural requirements of all directions in space. , so it has been widely used in building construction. [0003] In the prior art, there is an L-shaped composite column, which includes two box-shaped columns 6 and an angle steel 7 for reinforcing the two box-shaped columns. In actual production, one of the box-shaped columns is often raised through the frame body, and then the other box-shaped column is moved so that the edges of the two box-shaped columns are close to each other; after that, the two ...
