The invention discloses a construction method and a structure system of a prefabricated large plate filled wall concrete structure. The prefabricated large plate filled wall concrete structure systemcomprises a cast-in-place concrete structure and a prefabricated large plate filled wall, the cast-in-place concrete structure comprises a cast-in-place concrete column, wall and beam, and the insideof the cast-in-place concrete structure is filled with the prefabricated large plate filled wall. The construction method includes the steps: firstly, mounting the prefabricated large plate filled wall serving as a peripheral protective wall and an inner wall on a certain layer of a building once, and reserving a gap between the top of the filled wall and the bottom of the cast-in-place concrete beam; secondly, setting templates such as a main structure concrete column, a shear wall, a beam and a floor slab and binding reinforcement, taking the side face of a wall plate as part of a wall column side template and pouring main structure concrete; finally, reliably connecting the top of the filled wall with the bottom of the concrete beam to reliably connect the filled wall with a cast-in-place concrete main structure. The technical problems of low construction speed, poor quality and integrity, difficulty in hoisting and the like of a prefabricated large plate filled wall in a traditional construction mode are solved.
