본 연구에서는 기계식 후설치앵커 중 비틀림 제어 확장 앵커를 비균열콘크리트에 설치한 것으로 연구범위를 국한하고, 슬리브와 헤더를 개선한 국내 A사의 앵커를 시험대상으로 선정하여 콘크리트 강도와 앵커의 유효 묻힘깊이에 따른 단일앵커에 대한 인발시험을 수행하였다. 시험결과를 나타낸 것으로 모든 시험체 군에서 변동계수 15%이내의 성능을 나타내었고 이러한 결과로 볼 때 후설치앵커의 성능은 만족하고 있는 것으로 판단된다.

Anchors used in concrete structures are classified into cast-in-place anchors and post-installed anchors. At post-installed anchors, the effective embedment depth, measured from the concrete surface to the deepest point, is an important variable to grasp the performance of anchors. Because effective embedment depth is depth to transmit force to the concrete. In this study, we conducted pull-out test of M12 and M16 post-installed anchors, evaluated the performance of anchors.
