Earthquake-resistant anchor bolt, mounting structure using the same and post-processing for the anchor bolt

摘要

In an earthquake-resistant anchor bolt, a mounting structure using the same and a post-processing method for the anchor bolt, not only the vibration absorbing characteristics in the horizontal and vertical (lift) direction are superior but also the mounting strength of the object to be mounted to the base may be enhanced without curvature even if the structure is subjected to large lateral load due to the earthquakes. In the earthquake-resistant anchor bolt, a first support member (82) having a high compression elasticity is fixed to an outer circumference of a neck portion of a bolt body to be embedded in the base. A second support member (83) having a lower compression elasticity than that of the first support member is fixed to an outer circumference of a base portion inward of the neck portion of the bolt body. A fastening member has a threaded portion around which the fastening member is screwed at the bolt end portion.
