Abstract

See full text

The invention relates to a method and apparatus for securing an object to a support structure. The apparatus generally comprises a rod-shaped anchoring member provided with a longitudinal aperture therethrough. The anchoring member is externally threaded at a first end and at a second end is provided with a spiral groove adapted for receipt of a flexible wire. The anchoring member is also provided at the first end with a one-way valve. In practicing the method of the present invention, the anchoring member is positioned in an anchoring hole, or void, existing in the support structure. A hardenable and cementitious material is injected through the one-way valve until the anchoring hole is substantially filled with the hardenable and cementitious material. Thereafter the assembly is allowed to remain undisturbed until the hardenable and cementitious material sets and hardens.
