The invention discloses an efficient concrete stirring device for a building. The efficient concrete stirring device for the building comprises a stirring box. A stirring cavity is formed in the stirring box. A rotating shaft is vertically arranged in the stirring cavity. The upper end of the rotating shaft is rotatably connected to the inner top of the stirring cavity. Multiple rows of stirring rods are arranged on the rotating shaft in a penetrating mode. The stirring rods are fixedly connected to the rotating shaft. Movable stirring rods are vertically and symmetrically arranged on two sides of the rotating shaft. The two movable stirring rods penetrate through the multiple rows of stirring rods, and the two movable stirring rods are connected with the multiple rows stirring rods in a sliding mode, and limiting rings are fixedly arranged on the side walls, located between every adjacent two rows of stirring rods, of the two movable stirring rods in a sleeving mode. According to theefficient concrete stirring device for the building, the structure is reasonable, the operation is convenient, a plurality of raw materials of concrete can be stirred fast, sufficiently and uniformlyto obtain high-quality concrete, the quality of the project is improved in a certain extent, the impact force produced by stirring can be dissolved, and the efficient concrete stirring device is not affected.
