Abstract
The invention discloses a prefabricated reinforced concrete frame column and a frame structure. The prefabricated reinforced concrete frame column comprises a frame column body, a column wrapping steel pipe, a column steel end structure and a column steel connecting bracket. According to the connecting position of the external beam on the frame column main body, an inward annular groove is formed in the column reinforcement cage, the column outer wrapping steel pipe is arranged outside the annular groove of the column reinforcement cage in a sleeving mode, and the outer wall face of the column outer wrapping steel pipe is flush with the outer wall face of the column concrete main body; the column steel end head structure is embedded in the column concrete main body; every two adjacent frame columns are fixedly connected through a column steel end structure. The column steel connecting bracket is fixed between the column outer wrapping steel pipe and the outer beam. The frame structure comprises prefabricated reinforced concrete frame columns and main beams. A corresponding column steel connecting bracket is arranged on the outer wall of the column wrapping steel pipe of the prefabricated reinforced concrete frame column; and the end head of the main beam is fixed at the other end of the column steel connecting bracket. The structure and the construction process of the frame columns, the main beams and the secondary beams are simplified, the use of steel is reduced, and the construction efficiency is improved.
