| Zusammenfassung: | The invention provides a steel structure box-type steel column. The steel structure box-type steel column comprises a box-type steel column body, wherein the box-type steel column body is fixedly connected with a keel; the keel is filled with fireproof rock wool; the outer surface of the keel is fixedly connected with a fiber-reinforced calcium silicate board; a self-tapping screw penetrates through the outer surface of the fiber-reinforced calcium silicate board; the self-tapping screw sequentially penetrates through the fiber-reinforced calcium silicate board and the keel, so that the fiber-reinforced calcium silicate board is fixedly connected with the keel; and fireproof cement and water glass are arranged at the joint of the self-tapping screw and the fiber-reinforced calcium silicateboard and the joint of the self-tapping screw and the keel. The invention provides a fireproof wrapping method for the steel structure box-type steel column. The fire endurance of the box-type steelcolumn is improved, the co |
