Ultrathin externally-hung terrazzo-imitated plate and processing method thereof

The invention provides an ultrathin externally-hung terrazzo-imitated plate and a processing method thereof, and relates to the field of new building materials, the terrazzo-imitated plate comprises a surface layer and a structural layer, the structural layer is located on the back of the terrazzo-imitated plate, the structural layer is a reinforcing beam extending and protruding outwards, and at least three mounting sleeves are embedded in the reinforcing beam; different from a common waterstone-imitating plate pouring method, the method has the advantages that the structural layer is firstly poured, and then the fiber felt is used as the surface layer material for supporting, so that the colored stones of the surface layer material cannot sink into the structural material, the colored stone raw material is saved, and a waterstone surface layer with a better aesthetic effect can be made; the structural layer on the back face can be made into a complex installation structure according to a mold, compared with
