(57) The invention provides a connecting structure and method for a prefabricated veneer and a prefabricated concrete external wall panel, belongs to the technical field of prefabricated veneer construction, and aims to solve the problems of environmental pollution of a construction site and low construction efficiency as the number of construction steps of external wall decoration of old buildings is great, the efficiency is low and all dry and wet operations are directly completed on a wall operating surface. The structure comprises a prefabricated veneer, a prefabricated concrete external wall panel and a clamping piece, wherein a plurality of grooves are formed in the two butt-joint panels of the prefabricated veneer and the prefabricated concrete external wall panel in the thickness direction, and the grooves are formed at intervals in the length direction of the panel; after the prefabricated veneer and the prefabricated concrete external wall panel are in butt joint and clamped, the grooves are in one-to-one correspondence in the length direction of the panel surface, a clamping piece is embedded in each pair of grooves, one end of each clamping piece is fixedly embedded in the groove of the prefabricated veneer, and the other end of each clamping piece is fixedly embedded in the groove of the prefabricated concrete external wall panel. A gap between the prefabricated veneer and the prefabricated concrete external wall panel is filled with a bonding material.
