The multi-layer frame steel structure is generally composed of beams,columns,supporting structures,etc.,and its construction characteristics are"high,heavy,large and difficult".The multi-layer frame steel structure has developed into a new type in the field of industrial construction,which is mostly used in various equipment frames in smelting and petrochemical projects,and the frame steel structure has the advantages of good safety and stability performance,short construction period and flexible building layout.Combined with the smelting projects involved,through the production of frame columns,the blanking of box columns,the assembly of box columns,the welding of box columns,the assembly and welding of box columns,the installation of frame structures is analyzed in detail,and the construction process of multi-layer frame steel structures is analyzed,so as to provide a theoretical reference for the construction of multi-layer frame steel structures in the future.
