FOAM REDUCING VIBRATOR AND FOAM REDUCING METHOD FOR CONCRETE

摘要

PROBLEM TO BE SOLVED: To provide a vibrator reducing air bubbles on the surface of concrete, adjusting the space between the spade board and the mold form with ease.;SOLUTION: The air bubble reducing vibrator on the concrete surface has a vibrator body connecting a motor or a built-in motor, a spade board, and a joint part connecting the vibrator and the spade board. The air bubble reducing vibrator is constituted to satisfy the following conditions; (1) The spade board is connected to the vibrator body through the joint which joints at the deviated position from the center shaft of the vibrator body. (2) The spade board approaches the center axis of the vibrator body than the joint position with the vibrator body of the joint part. (3) The spade board is substantially parallel to the center shaft of the vibration body. And further, the bubble reducing vibrator is favorable when it has a spacer.;COPYRIGHT: (C)2006,JPO&NCIPI
