Through the connection assembly 200, the steel column member 100 can be inserted into the connection cylinder 210 from the insertion hole 220, and then the outer side is fixed by using the angle plates 230. At this time, the end of the steel column member 100 is located between the clamping plate 250 and the inner fixing plate 270. After tightening the bolt 260, the steel column member 100 is fixed by using the clamping plate 250 and the inner fixing plate 270. Compared with the traditional connection method, this solution not only has higher connection strength, but also the inner connection and fixation can reduce the corrosion of the steel column member 100 and improve the service life of the steel column member 100.
