The present disclosure relates to a fabricated concrete connection structure and a construction method, the structure including shear wall members. Tops of the shear wall members are fixedly connected to a plurality of connection female heads, and the plurality of connection female heads are arranged at equal intervals along length directions of the shear wall members. Reinforcing cage pre-formed holes penetrate through the tops and bottoms of the shear wall members. A plurality of connection male heads are arranged at equal intervals along the length directions of the shear wall members, and the plurality of connection male heads are in one-to-one correspondence with the plurality of connection female heads. One sides of the bottoms of the shear wall members are fixedly connected to folding plates. The present disclosure can achieve the purpose of connecting the shear wall members conveniently and quickly, improving the efficiency and quality of construction.
