Combined veneer structure and mounting method thereof

The invention discloses a combined veneer structure and a mounting method thereof.The combined veneer structure comprises a veneer and a connecting piece, the veneer and the connecting piece are connected in an inserted mode, the veneer comprises a veneer body, a set of milling grooves are formed in the back of the veneer body, the connecting piece comprises a connecting piece body, and a set of milling grooves are formed in the back of the connecting piece body. A milling groove is formed in the side, facing the wall surface, of the connecting piece body, a protrusion matched with the size of the milling groove is arranged on the side, matched with the veneer, of the connecting piece body, and the veneer and the connecting piece are inserted into the milling groove through the protrusion. The elastic cramps are arranged on the connecting grooves, so that the combined veneer can be directly connected with a preset vertical keel, the use amount of screws is reduced, the time required for installing the veneer
