Steel box column Structure, so named because of its shape like a large iron box. Generally, steel structures are used as beams or columns. Steel column box, corrosion resistance and high strength. The main structure of the box column adopts a steel frame-support system. The load-bearing frame is a box-section column and an H-beam. The processing and production of the box column is mainly made of steel plate, which is produced through batching, assembly, welding and other processes, and finally shot blasting and rust removal, and painting is completed.

Introduction of Box Column Steel Structure
Box Column Steel Structure is a composite column, which is assembled from steel plates. The circular steel pipe column generally bears the axial force or the parts with less eccentric force, while the box-shaped steel pipe column can have a larger cross-section in one direction, which determines that it can be used in places with a large eccentric force. From the point of view of production, the production of round steel pipe columns is relatively simple, while the production of Box Column Steel Structure is relatively difficult to produce due to the relatively large amount of welding and easy deformation, etc. As a box-type steel pipe column, the wall square tube has the advantages of direct molding, low material cost, good material performance, high strength and easy installation.
Box Column Steel Structure Craft
Box Column Steel Structure is blanked by CNC flame cutting machine to cut the column plate. The beveling method is carbon arc gouging to cut the K-shaped bevel. After the blanking is completed, it is straightened and corrected. In order to make the column body plate assembly accurate, it is necessary to prepare and assemble The fetal membrane, the assembly sequence is: first the upper cover plate is the benchmark, then the assembly line of the diaphragm and the side web plate is released, and the U-shaped assembly is carried out, and then the lower cover is assembled and then welded. The main body of the column is welded by submerged arc automatic Welding, stiffening plate welding is carried out by manual welding of electric welding machine, and then one side of the clapboard is welded by electroslag pressure welding, and the arc-starting plate is set for welding. After the box column is welded, it is straightened and corrected, and then the end is cut with an end milling machine. The box-shaped column is painted in strict accordance with the standard rust removal and oiling. After the box-shaped column is made, it will be inspected and numbered by full-time quality inspectors.
Assembly Process of Box Column Steel Structure
The Production and Assembly of the Box Column Steel Structure is the Key, and the Assembly Process is As Follows
First, the upper cover plate is used as the assembly reference, and the assembly lines of the partition plate and the side web plate are respectively released on the assembly surface according to the requirements of the construction drawing, and marked with a sample punch.
Assemble the upper cover plate and the partition plate first, and then assemble them on the tire mold. After the assembly is completed, the welding must be completed before the next process.
Before assembling the web, check the straightness of the web. When assembling, use one direction to assemble, first locate the middle stiffener, and then locate the web.
The overall assembly of the Box Column Steel Structure is carried out after the U-shaped structure is completed. First, correct the edge of the U-shaped structure web to make its unevenness <L/1000, and then release the web assembly positioning line on the lower cover. Type structure assembly, using one direction assembly, positioning spot welding using symmetrical welding method.
Then one side of the separator is welded by electroslag pressure welding, and the equipment is welded by electroslag pressure welding.
