| 摘要 |
The invention concerns a process for installation of an expansion anchor device, which is used to secure a part to the surface of a structural support member. The anchor device comprises an expandable sleeve (1), mainly extending along a longitudinal axis (X-X) with a proximal end (2) and a distal end (3), which is designed to be placed within a hole formed in the structural member that is designed to have the anchor applied thereto. In the process, once the hole has been formed in the support member and said anchor device has been placed in the hole, a step of orienting the sleeve (1) is carried out, such that the expansion of the latter occurs along the highest-resistance direction of the structural support member. The invention also relates to an apparatus for carrying out the process, which comprises a cylindrical bushing (26) having an axial through hole (27), front coupling means (28) located at the end (29) of the bushing facing the sleeve (1) of the anchor device, said means (28) being adapted for engagement with front counter-coupling means (30) placed on the proximal end (2) of the sleeve (1) of the anchor device as well as a handle (31) connected to said bushing (26). |
