Abstract
PURPOSE: To improve compaction effect and quality and achieve labor saving by providing linear or helical projected and recessed surfaces on the surface of a vibrator body of the bar-shaped concrete vibrator or forming the outer shape of the vibrating body to a conical shape. CONSTITUTION: A straight or helical cut trench 12 is provided on the surface of a vibrating body section 11 of a bar-shaped concrete vibrator, or the outer shape of vibrating body section 11 is formed to a conical shape and a plurality of lines of cut trenches 12 are provided as required. In this way, it specially acts effectively to the compaction of stiff-consistency concrete and also for ordinary concrete, it is effective for enlarging effective compaction range, reducing vibration time by quick liquefaction effect, rationalization of workability and labor saving by reducing the number of places for inserting the vibrator, and also the enhancement of the quality of concrete.
