Title:
VIBRATION SUPPRESSION BODY OF HANGING BOLT
Document Type and Number:
Japanese Patent JP2016169751
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To restrict vibration of a hanging bolt, prevent deformation or damage of the hanging bolt and at the same time restrict oscillation of a hanging structure.SOLUTION: This invention has a constitution that is fixed to a hanging bolt 3 from a ceiling body 2 and fixed for hanging a hanging structure so as to reduce vibration load acted on the hanging bolt 3 and restrict vibration, a vibration restricting body 1 forms a conical shape having a resilient plate-like material wound around it, a top point portion of this conical shape is positioned low and at the same time this top point portion is formed with a through-pass hole 11 through which the hanging bolt 3 is inserted and passed under a close-contacted state. Further, a conical-shaped expanded end part 12 is fixed under an inserted state in the hanging bolt 3 while being abutted against the lower surface of the ceiling body. When vibration energy is inputted against the hanging bolt 3, a resiliency of a slant portion of the conical shape realizes a biasing force in a direction opposite to a vibrating direction of the inputted vibration energy so as to restrict or diminish the vibration energy.SELECTED DRAWING: Figure 1
