The box section has good bidirectional bending resistance and torsion resistance, can better meet the strength and the overall structural stability of the steel column, and is commonly used for multi-high-rise steel structure buildings.

Due to the need of the stress of the box column structure, the horizontal stiffening partition inside the box column must use a welded butt weld. Because of the limitation of the cross-sectional size of the general box column, a welder cannot enter the box column for welding, so that the box column cannot be manufactured by adopting square tube profiles, and a steel plate assembling and assembling manufacturing process with complex process, labor and material consumption and poor accuracy has to be adopted.
The specific manufacturing method comprises the following steps: the method comprises the steps of cutting four strip steel plates to serve as the wall plates of the box column, firstly assembling three strip-shaped wall plates into a U shape, then placing a stiffening partition plate, welding three welding seams between the partition plate and the wall plates, covering the rest strip-shaped wall plates to form the box, carrying out submerged arc welding on the long groove plate seams on four edges of the box column, and finally welding the last welding seam on the stiffening partition plate by using an electroslag welder. The manufacturing method has the defects of complex process, large welding amount, high consumption of materials, high processing cost, serious stress concentration phenomenon, easy deformation of the box column and difficult correction.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The embodiment of the invention provides a manufacturing method of a box column, which comprises a square tube section bar (shown in figure 1) with a certain specification, a stiffening baffle plate and a lining plate (shown in figure 3) which are positioned in the square tube section bar; a round hole is formed in the center of the stiffening partition plate (shown in fig. 2), a single-sided groove is formed in four sides of the stiffening partition plate, and a lining plate is assembled on the back face of the single-sided groove of the stiffening partition plate as shown in fig. 3 by way of example. The manufacturing method comprises the following steps:

Step S102, welding a stiffening baffle in a square tube section, specifically comprising the following steps:
And S1021, pushing the stiffening partition plate and the lining plate to a preset position in the square tube section, wherein a single-sided groove of the stiffening partition plate faces to a welding side, and the welding side is the side where welding equipment is located during welding.
Step S1022, pushing the lining plate away to push the inner wall of the square tube section. In particular, part of the components of the welding equipment can pass through a round hole in the center of the stiffening partition plate so as to push away the lining plate on the other side of the stiffening partition plate.
In order to facilitate the subsequent welding of the stiffening baffles, the stiffening baffles are not offset in position, and optionally, step S1023, fixing the stiffening baffles and the lining plate in the square tube section by arc spot welding. Illustratively, at least one weld is formed between the stiffening baffles and each inner wall of the square tube profile by arc spot welding to secure the stiffening baffles and the square tube profile together.
Step S1024, as shown in FIG. 5, welding the welding seams between the stiffening partition plates and the inner walls of the square tube sections in sequence. When the stiffening partition plates are welded, single-sided grooves are formed in four sides of the stiffening partition plates, so that single-sided full penetration welding is easy to realize; and when the stiffening partition plate is welded, the welding rod is melted, filled and solidified to form a welding line between the stiffening partition plate and the inner wall of the square rectangular tube section, and the lining plate on the back of the single-sided groove assists in forming the single-sided welding line, so that the welding effect of the stiffening partition plate is ensured.
When the inclined angle of the square tube section is smaller than 30 degrees, the square tube section is placed too flat, the phenomena of partial welding and undercut easily occur during welding, and the welding effect of the stiffening partition is poor. When the oblique angle of the square tube section bar is larger than 45 degrees, one end of the square tube section bar, which is high, is too high, so that the operation difficulty in welding the stiffening partition plate is increased.

On the other hand, when the stiffening partition plates are welded in the square tube section bar, all welding of four welding seams of the partition plates is completed, so that electroslag welding is not needed, welding quantity and welding consumable consumption are reduced, and manufacturing cost of the box column is further reduced.
After the stiffening partition plate and the lining plate are pushed to the preset position in the square tube section, two horizontal welding seams and two vertical welding seams are formed between the stiffening partition plate and the inner wall of the square tube section. In order to facilitate the welding of the respective welds in sequence, step S1024 may optionally include: and the horizontal weld joints positioned below the two horizontal weld joints are welded, and the single-sided groove on the side of the stiffening partition plate is upward turned up, so that the single-sided full penetration effect is easier to realize: and rotating the square tube section by 90 degrees in sequence so as to weld the stiffening baffle and the other three welding seams between the inner walls of the square tube section, thereby completing the welding operation of one stiffening baffle.

Because the square tube profile is generally longer, if the welding position of the stiffening partition is too deep, the difficulty of welding the stiffening partition is increased, and based on this, the step S103 preferably includes:
Step 1031, repeating the step S102 for a plurality of times according to the sequence from far to near, so as to sequentially weld a stiffening baffle required by one end of the square tube section bar which is high after being obliquely placed in the square tube section bar; step 1032, turning the square tube section bar so that the other end of the square tube section bar is at the high end, repeating the above step S102 for a plurality of times according to the sequence from far to near, so as to sequentially weld the stiffening baffle required by the other end of the square tube section bar in the square tube section bar.
