Title:
SUSPENDED VIBRATION CONTROL DEVICE
Document Type and Number:
Japanese Patent JP3234819
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a suspended vibration control device capable of preventing the drop of an interior ceiling material even without a steel cord for the drop prevention.
SOLUTION: The upper end of drop prevention hardware 28 is fixed to a ceiling slab 12 by use of a nut 26 and an anchor bolt 24. Also, a circular hole 38 is drilled through a horizontal part 28B at the lower end of the drop prevention hardware 28, and a hanger bolt 34 for suspending an interior ceiling material 16 is led through the circular hole 38. As a result, a support plate 20 for supporting the hanger bolt 34 is suspended from the horizontal part 28B of the drop prevention hardware 28, even when a large load acts on the interior ceiling material 16 and vibration control rubber is broken. Thus, the interior ceiling material 16 does not fall at all.
