Steel column connecting joint and prefabricated building

Abstract

The application relates to a steel column connecting joint and a prefabricated building, and the steel column connecting joint comprises a first connecting piece and a second connecting piece. The first connecting piece comprises a first steel hoop and a positioning tenon, the first steel hoop is fixedly connected with a first column body, the positioning tenon is fixedly arranged on the inner wall of the first steel hoop, and the positioning tenon is partially exposed to the outside of the first steel hoop. The second connecting piece comprises a second steel hoop and an inner lining barge, the second steel hoop is fixedly connected with a second column body, the inner lining barge is fixedly arranged on the inner wall of the second steel hoop, and the inner lining barge has a preset distance from the opening end of the second steel hoop. In the connecting state, the first connecting piece is located above the second connecting piece, the positioning tenon is at least partially inserted into the second steel hoop, and the end of the positioning tenon abuts against the inner lining barge. The steel column connecting joint can effectively guide the accurate alignment of the upper steel column and the lower steel column, is convenient for on-site assembly, and thus the installation quality and the installation efficiency are improved.
