What is steel structure assembly? Be specific!

Steel structure assembly is a field hoisting process and its preparation steps. It is to assemble and shape the components of large components on the flat ground, or to transport simple components to the site and hoist them in place. For example, the solid column of a light steel portal frame is hoisted in place, even if the anchor bolt is put on, the assembly is completed, excluding the adjustment and correction of the column and the stability of the column foot.

Submerged arc welding was carried out in the previous factory, which belongs to production and assembly belongs to installation.

The word zuli first appeared in Japan, which means the same as assembly, but it is more vivid.

For example, the assembly of H-shaped steel columns can be divided into primary assembly and secondary assembly.

One-time assembly: three-piece positioning welding of H-beam is considered as one-time assembly. Then, after submerged arc welding completes the main weld, the secondary assembly begins. Secondary assembly is to assemble other small parts, such as connecting plates and brackets, onto H-beam and fix them by positioning welding, which is the completion of secondary assembly.
