The invention provides a European style building space stone ground pattern integrated composite splicing structure. The structure comprises a plurality of stone panels which are provided with pattern patching parts in an inlaying mode; the pattern patching parts are inlaid in preformed grooves in the stone panels; a metal inlay is arranged in each groove; an inlay groove is formed in each metal inlay; the inner wall of each inlay groove is in camber-surface transition with the bottom of the inlay groove; a triangular cavity is formed in the position, where each metal inlay is located, of a corresponding camber surface; the camber surfaces right face the base angle parts of the pattern patching parts; and the pattern patching parts are inlaid in the grooves through the metal inlays. According to the European style building space stone ground pattern integrated composite splicing structure, the technical problems that in stone pattern patching structures in the prior art, the inlaying flatness is low, and patterns are prone to being deformed can be solved.
