The invention discloses a core-through type pillar base slate, drum step stone, reinforced concrete upright column structure, which comprises a pillar base slate, a drum step stone and a reinforced concrete column body. The utility model is characterized in: the pillar base slate and the drum step stone are formed with a core through hole; the reinforced concrete column is passed through the core through hole, and is combined with the plinth to form an integrated structure. The construction method comprise includes forming core though holes on the pillar base slate and the drum step stone, has the following construction processes: measuring and setting line, forming the core through hole on the pillar base slate, positioning the drum step stone and fixing, binding column steel bars, supporting moulds, pouring column concrete, removing moulds, maintaining, and machining and modifying the reinforced concrete column surface, the pillar base slate and the drum step stone. By integrating the column body, the drum step stone and the pillar base slate, the invention improves the integrity and spatial aesthetic feeling of the great wooden framework in archaize building, achieves great environment benefit, increases machining efficiency greatly, saves material, and protects environment.
