Title:
COOPERATION MECHANISM OF ANCHOR BOLT AND FRICTION-VIBRATION DAMPING DEVICE
Document Type and Number:
Japanese Patent JP2022185562
Kind Code:
A
Abstract:
To provide a cooperation mechanism of an anchor bolt and a friction-vibration damping device which dispenses with insertion of an anchor bolt into a friction-vibration damping device, has no restriction in an installation place, and has no limit of a behavior of the anchor bolt.SOLUTION: A cooperation mechanism has a nut with a round seat screwed in an anchor bolt and a through hole where the anchor bolt penetrates through a sill. The through hole has a first through hole and a second through hole in order from the surface of the sill. A diameter of the second through hole is larger than a diameter of the first through hole, and a length of the first through hole is longer than a long nut part of the nut with a round seat. A friction-vibration damping device has a first slipping flat plate which is positioned in the upper stage and comes in contact with the sill, and a second slipping flat plate which is positioned in the lower stage and comes in contact with the foundation. A surface where the first slipping flat plate and the second slipping flat plate overlap each other is smooth, and the anchor bolt fixed with the nut with a round seat and the friction-vibration damping device are cooperated with each other and resist earthquake.SELECTED DRAWING: Figure 1
