The present invention relates to the technical field of construction measures for existing buildings, and discloses a method for reconstructing rows of small-section buildings that fully utilizes old buildings. In the present invention, the door and window holes that need to be opened for the reconstruction of old buildings are gathered together to form vertical strip-shaped construction holes with lintels and hidden columns, which does not affect the vertical bearing capacity and overcomes the interference caused by the exterior walls of the old buildings to the internal major renovation construction. After overcoming the interference, a new set of load-bearing walls can be implanted to carry the newly added floors, avoiding the problem of relying solely on the old load-bearing walls to carry the newly added load. Then, the previously non-interference columns are implanted and together with the frame beams, a stable three-dimensional beam-column grid is formed. After the construction on the exterior wall of the old building is completed, the previously non-interference columns are expanded horizontally outward to form plate-shaped composite columns. When overcoming the influence of the opening on the lateral force resistance of the old building, it will not interfere with the construction on the exterior wall of the building, and after the cantilevered corridors are installed on the plate-shaped composite columns, the old buildings can be connected without side effects. Finally, the excess vertical bearing capacity is fully utilized by the top board house.
