Rear anchoring device of cantilever steel beam

The utility model discloses a rear anchoring device of a cantilever steel beam. The rear anchoring device comprises bearing plates attached to the front side and the rear side of a concrete column respectively. The left ends and the right ends of the bearing plates on the front side and the rear side exceed the concrete column, and split bolts are connected between the exceeding parts on the left side and the right side correspondingly. And the outer side surface of one of the four hoop plates is fixed with the end part of the cantilever steel beam. The four hoop plates surround the outer side of the concrete column, and the side edges are welded end to end. The lower side edge of at least one of the four hoop plates makes contact with the upper side edge of the bearing plate. The bending moment transmitted from the cantilever steel beam is ingeniously resisted by the extrusion force between the steel hoop and the concrete column. Compared with the traditional connection which depends on the bonding of anchor
