The invention relates to a construction method of a bearing platform-beam column joint replacement advance reinforcement hoop structure. Shortcomings that the existing bearing platform becomes a joint weak region in a basement storey adding project, and large potential safety hazards of the project are easily caused are overcome. The construction method comprises the following steps of A, manufacturing a first-stage hoop structure; B, manufacturing a second-stage hoop structure; and C, dismounting the first-stage hoop structure and chiseling off bearing platform concrete on the outer side of an anchor rod of the second-stage hoop structure. Through stretching of the anchor rods and slip casing by pressure, mechanical performance of the hoop structures is controlled accurately, and joint load carrying of concrete of original core regions of the closed hoop structures and a bearing platform is guaranteed. In whole construction, safety and adaptation are high, bearing platform-beam column core region structure replacement can be finished under the condition that functions of an upper structure are not affected, and various detailing requirements on beam column joints and actual stress requirements in a basement storey-adding projection in Chinese standards can be met.
