The invention discloses a laminated plate joint construction treating method and a structure thereof. The main technical scheme comprises the steps that before laminated plates are hoisted, a full-length double-faced adhesive is pasted to one side faces of the laminated plates; after the laminated plates are hoisted, a worker smears a layer of cement mortar with the small slump degree in a plate joint; and constructional steel bars are bound on the plate joint of the laminated plates, the transverse steel bars are located on the lower portion, and the longitudinal steel bars are located on the upper portion. The construction progress of the whole project is accelerated, input of building materials and construction workers is reduced, and the positive effects are achieved on the aspects such as the environmental influence, construction quality and construction progress.
