The invention relates to the field of building curtain plate assembly, in particular to a device for efficiently laying a curtain plate in a building field. The device comprises a double-layer base, a feeding assembly, a stabilizing assembly, a driving assembly and a laying assembly; the feeding assembly is arranged on the side of the double-layer base; the stabilizing assembly comprises four pressing mechanisms; the driving assembly comprises a lifting mechanism and a first translation mechanism used for transverse movement; and the laying assembly comprises a laying mechanism, a rolling mechanism, a second translation mechanism and a rotating mechanism. According to the device, through the arrangement of the driving assembly, the device can be precisely moved to an area where the curtain plate needs to be laid, so that the laying precision is improved; through cooperative operation of the paving mechanism, the rotating mechanism, the second translation mechanism and the rolling mechanism, the curtain plate can be efficiently paved, and meanwhile, the paved curtain plate can be rolled, so that the firmness between the curtain plate and a wall is improved; and through operation of the feeding assembly and the paving mechanism, the automatic transportation is achieved, the investment of labor force is reduced, and then the economic expenditure is reduced.
