| 摘要 |
The present invention relates to an anchor structure and, specifically, to an anchor structure with an improved structure to secure a stable mounting force by preventing rotation blades embedded into the inner wall of a drilled hole from rotating beyond the elastic supporting limit of a spring member using a rotation prevention unit when a tension member applies a tensile force. The purpose of the present invention is to provide an anchor structure having a simple structure which improves a fixating force towards the drilled hole and secures a sufficient supporting force when an anchor body is mounted on a mounting part. |
