The invention discloses a sand screening device for construction, and belongs to the field of architectural engineering. The sand screening device for construction comprises a screening box and a vibrating screen plate, wherein the drive end of a motor is connected with a third rotary shaft; one end, away from the inner side wall of a drive cavity, of a fourth rotary shaft passes through a partition, extends into a screening cavity, and the extending end is connected with a dispersing assembly; one end, away from the third rotary shaft, of a first linking assembly is connected to one end, inside a drive shaft, of a second rotary shaft; one end, away from a rotary rod, of a transmission assembly is connected to the rod wall, inside the drive cavity, of the fourth rotary shaft; and one end,away from a rotary rod, of a reciprocating mechanism is connected to the side wall of the vibrating screen plate. The motor works to drive a first pressure roller and a second pressure roller for pressing sand through the first linking assembly, the dispersing assembly disperses pressed sand onto the vibrating screen plate, and the reciprocating mechanism drives the vibrating screen plate to shakeback and forth to perform sand screening, so that sand screening speed is quickened, and working efficiency of the device is improved.
