The invention provides a fabricated concrete floor system-plate surface joint and a joint connecting method, and relates to the floor system-plate surface joint and the joint connecting method. The fabricated concrete floor system-plate surface joint and the joint connecting method solves the problem that a structural system is destroyed caused by large in-plane deformation and out-of-plane deformation due to fastening invalidation of an existing fabricated concrete floor system connected by welding of conventional assembling cover plates under action of an earthquake. The fabricated concretefloor system-plate surface joint comprises a groove-shaped embedded piece and connecting cover plates; and the groove-shaped embedded piece is mainly composed of anchoring bars and groove-shaped steel, anchoring bars pre-embedded in a prefabricated floor slab are fixedly connected to the inner side faces of two web plates of the groove-shaped steel, the connecting cover plates are fixedly connected to the outer side faces
