Title:
OSCILLATION PREVENTIVE TOOL OF HANGING AND SUPPORTING DEVICE AND OSCILLATION PREVENTIVE STRUCTURE USING OSCILLATION PREVENTIVE TOOL
Document Type and Number:
Japanese Patent JP2015175490
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an oscillation preventive tool of hanging and supporting device capable of effectively absorbing oscillation of the hanging and supporting device and preventing breakage loss of a hanger bolt even when oscillation caused by fine vibration occurs as well as substantial oscillation of the hanging and supporting device due to earthquake.SOLUTION: An oscillation preventive tool 10 is constituted by a frame 12 and an attenuation member 14. A hanger bolt B vertically arranged from a ceiling T of a building is inserted into the frame 12 and fixed to a screwing base part Z of the hanger bolt B into the ceiling T while being contacted with the ceiling T of the building. The attenuation member 14 is cylindrical in its shape, fixed in the frame 12 to its bottom part, a bolt insertion hole for inserting the hanger bolt is formed and it is resiliently abutted against the hanger bolt B at the bolt insertion hole when the hanger bolt B is oscillated around a fulcrum point of the screwing base part Z for the ceiling T. An upper horizontal piece constituting the ceiling surface part of the frame 12 contacted with the ceiling T is provided with a frame fixing part 18 fixed to the screwing base part Z.
