Box Steel Column/ Welded Structural Steel Fabricators / Box Type Metal Process

General:

Box Steel Column/ Welded Structural Steel Fabricators / Box Type Metal Process. Welded steel box beam and box column is widly used in the steel structure proejct,Since the H-shaped steel column has only one strong axis, in the case where the force is relatively complicated at the joint of the beam and column, the first is that the "node domain" cannot meet the requirements, and the second is according to the principle of "strongly connecting weak components". When the internal force of the seismic combination is elastically designed, the ultimate bearing capacity check cannot be satisfied. Because the box column is a strong axis in the X and Y directions, and a stiffening plate at the node, a strong node domain is formed, and the force condition is superior to that of the rolled H-beam.

We could fabricate it in many ways or as your request. Here we will show you one of the fabriation method.

One of the fabrication method of box beam & box column:

The box-shaped column is welded by four steel plates, and the manufacturing process is basically the same as that of the welded H-shaped steel. 

The box-shaped column is cut by the numerical control flame cutting machine for the column plate cutting. The opening method is carbon arc gouging and cutting the K-shaped groove. After the blanking is completed, the straightening correction is carried out. In order to ensure the accurate assembly of the column body, it is necessary to prepare the assembled tire. Membrane, the assembly sequence is as follows: firstly, the upper cover plate is used as a reference, then the assembly line of the transverse partition plate and the side web is discharged, U-shaped assembly is performed, and finally the lower assembly is assembled and welded, and the main body of the column is welded by submerged arc welding. The welding of the stiffening plate is manually welded by a welding machine, and finally the method of welding the electroslag pressure welding of the separator is carried out, and the arc runner is welded. After the box column is welded, the straightening correction is performed, and then the end milling machine is used for the end cutting. The box column coating is strictly rusted and brushed according to the standard. After the box column is finished, it will be inspected and numbered by the full-time quality inspectors. Box-type column fabrication and assembly is the key.
