Among various prefabricated structures, steel structures offer numerous advantages, including rapid construction, minimal on-site wet work, ease of industrialization and standardization, easy quality control, and environmental friendliness. These inherent advantages hold significant promise for future development in the prefabricated building sector. Existing steel structure beam-column connections are typically welded. However, welded beams and columns require destructive disassembly using cutting machines and other equipment, making them difficult to reuse and resulting in a waste of resources.

[0003] According to the authorization announcement number CN 220035699 U, a prefabricated beam-column structure is disclosed, comprising an upper steel column, a lower steel column, and crossbeams located on both sides of the upper steel column.

Several sets of auxiliary support plates 6 are symmetrically installed inside the connecting steel plate 5. A set of cross support frames 10 are welded inside each set of auxiliary support plates 6. The auxiliary support plates 6 on each side of the connecting steel plate 5 are used to auxiliary connect the load-bearing H-steel 3 on the outer sides of the upper steel column 1 and the lower steel column 2. After the upper steel column 1 and the lower steel column 2 are plugged in and stabilized, the connection is strengthened.

[0027] The pressure-sharing assembly includes four groups of outer jacket protection plates 12 attached to the outside of the upper steel column 1 or the lower steel column 2.
