description | Post-installed anchors are used in many existing concrete structures to construct additional members. The purpose of this study is to investigate the pull-out behavior of a post-installed adhesive anchor under pull-out load. The post-installed adhesive anchor, which is employed with the epoxy resin to obtain the chemical bonding, has been newly developed. In this study, the single adhesive anchor was installed into concrete which was cast in steel pipes and into concrete slabs. The test parameters were the embedment length and concrete strength. From the results of the pull-out test, the bond strength related to the concrete strength without the embedment length. As the mechanical and chemical resistances of the adhesive anchor, the bond strength was highly obtained in comparison with the common adhesive anchors. Furthermore, the pull-out and torque tests were carried out on concrete slabs. From the test results, the ultimate tensile load linearly related to the torque. This relation can be employed for the inspection of the post-installed adhesive anchor after construction. |
