Steel column assembly, prefabricated steel column module, steel structure, shear wall and modular building

Abstract

This application provides a steel column assembly, a prefabricated steel column module, an assembled steel structure, a prefabricated shear wall, and a modular building, relating to the field of modular prefabricated buildings. The steel column assembly includes a first steel column and a second steel column. The first steel column is a hollow columnar structure including multiple crossbeams extending along a predetermined direction. The second steel column is also a hollow columnar structure, with welding grooves extending along a predetermined direction formed on its sidewalls. The first steel column is embedded within the second steel column, and the welding grooves correspond to at least a portion of the crossbeams. The first and second steel columns are welded and fixed at the welding groove positions. After welding, the crossbeams of the first steel column protrude from the inner sidewall of the second steel column, thus forming a pull-out resistant structure, which is beneficial for improving the pull-out resistance between the end joints of the upper and lower steel structures after cement pouring. Furthermore, this structure is easy to operate, can improve welding speed and production efficiency, and is conducive to the automated production of modular buildings.
