Title:
EXCITING DEVICE FOR CONCRETE FORMWORK
Document Type and Number:
Japanese Patent JP3134051
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To widen a range in which an exciting force is increased and decreased.
SOLUTION: A timing belt 30 is hooked and stretched on a driving gear pulley 26 and a gear pulley 29, passing from the upper side of a first tension pulley 12 to the lower side of a second tension pulley 15 through the lower side of a first gear pulley 13 and the upper side of a second gear pulley 14 and at the same time, passing through the upper side of a third tension pulley 16 to the lower side of a fourth tension pulley 19 through the lower side of a third gear pulley 17 and the upper side of a fourth gear pulley 16. In addition, sliding bases 20, 21 are transferred into a parallel direction to the timing belt 30 with the help of a hydraulic cylinder 23. Further, an eccentric plumb bob is rotated by the first gear pulley 13 or the forth gear pulley 16 to vibrate a concrete formwork 40.
