Each double-steel tube column includes an internal steel tube and an external steel tube. The joint connector includes an internal connecting tube and an external connecting sleeve which are both circular steel tubes. The internal support member is a columnar structure and has two ends regularly formed with bolt holes in a circumferential direction. Each external ring plate comprises a horizontal portion and an annular portion perpendicular to the horizontal portion.
