<P>PROBLEM TO BE SOLVED: To provide an earthquake strengthening structure by an adhesive system anchor, capable of improving anchor construction to be affected by the leakage of an adhesive from a borehole and improving an earthquake strengthening performance by utilizing the leaking adhesive. <P>SOLUTION: In the earthquake strengthening structure, by crushing an adhesive enclosed capsule housed inside a borehole 3 formed in an existing concrete skeleton 2 by an anchor 5 inserted into the borehole, the anchor is projected from the existing concrete skeleton and fixed by an adhesive A filled inside the borehole, and an earthquake strengthening member 10 is joined to the existing concrete skeleton through the anchor. At a joint boundary B of the existing concrete skeleton and the earthquake strengthening member, by installing an adhesive receiver 1 for collecting the adhesive leaking out from the borehole around an opening hole portion 3a of the borehole to a surface of the existing concrete skeleton, it is accumulated and hardened on the inside, and a projection part 13 projected from the surface of the existing concrete skeleton is formed by the adhesive exposed by the removal of the adhesive receiver. <P>COPYRIGHT: (C)2012,JPO&INPIT |
