BATTER

PURPOSE:To eliminate a need for a vibrator during a work to assemble forms and to relieve a labor and a time by mounting eccentric members on the rotary shaft of a rockable motor arranged in a pipe member and generating vibration at the pipe member. CONSTITUTION:A rockable motor 22 is arranged in a pipe member 20 and around a transversal line, and eccentric members 26... are mounted on the rotary shaft of the motor 22 to form batter members 10 and 10. A plurality of the batter members 10 are laterally or longitudinally arranged such that the transversal line extends at right angles with a weir plate 12. When the motor 22 is run, the eccentric members are rotated together with the rotary shaft, and the eccentric members 26 are rocked around the transversal line together with the motor 22. The eccentric members is collided with the inner wall of the pipe member 20, and vibration in the direction of the transversal line is exerted on the pipe member 20. Vibration is transmitted to poured concrete through the weir plate 12.
