Title:
VIBRATION SUPPRESSION BODY FOR HANGER BOLT
Document Type and Number:
Japanese Patent JP2016194345
Kind Code:
A
Abstract:
PURPOSE: To provide a vibration suppression body for a hanger bolt capable of restricting vibration of the hanger bolt, preventing deformation or damage of the hanger bolt and at the same time suppressing oscillation of a hanging structure.CONSTITUTION: This invention relates to a vibration suppression body for a hanger bolt that is fixed to the hanger bolt hung from a ceiling body to hung down a hanging structure, reduces vibration load acted on the hanger bolt, and suppresses vibration. Lower ends of three or more rod-like resilient bodies are bundled, expanded to open in a radial manner from the bundled portions in an upward direction, hanger bolts are inserted and passed inside the bundled fixing part of the rod-like resilient bodies to cause the inner surfaces of the bundled fixed portions to be closely contacted with the outer periphery of the hanger bolt and at the same time the vibration suppression body is fitted and fixed to the hanger bolt under a state in which each of the upper ends of the rod-like resilient bodies is abutted against the lower surface of the ceiling body. When vibration energy is inputted against the hanger bolt, resilient characteristics of the rod-like bodies realize a biasing force in a direction opposite to a vibrating direction of the inputted vibration energy to cause the vibration energy to be restricted or diminished.SELECTED DRAWING: Figure 1
