Steel components

It got its name because of its shape like a big iron box. Steel structures are generally used as beams or columns.

Structural features: The box-shaped column is composed of 4 plates (that is, 2 cover plates and 2 webs). According to the strength requirements, the four fillet welds are designed into full melting groove (CP) and partial melting groove (PP). Two forms.

The box-shaped column is provided with a transverse partition, the main transverse partition and the web are welded by electroslag welding nozzles, and the ordinary transverse partition and the cover web are welded on three sides. The outer side of the box-shaped column is provided with a column and an eye plate, which are connected with the main beam, the secondary beam and the vertical supports of each elevation. The connection between the column and the column adopts a combination of welding and jacking. Prefabricated building

The specific drawings will be different and changed. Some are like "#", all four sides come out, some are like "mouth", and of course some are semi-sealed. Therefore, the processing of the box-shaped column must have drawings, and sometimes some ribs are added to the column. Some people use large rectangular tubes instead of box columns. However, the production capacity is limited, and the thickness is often not up to the requirement. Most of the box columns are welded by submerged arc welding, and one of the joints requires special welding, which is more difficult. Generally domestic steel structure factories can do it, but each has a different price.
