Method and apparatus for securing an object to a support structure

A method for securing an object to a structure provided with an anchoring hole, comprising the steps of:

• a. inserting into said anchoring hole a rod-shaped anchoring member provided with an aperture longitudinally therethrough, said anchoring member being externally threaded at a first end thereof and having at the second end thereof a spiral groove, one end of which is positioned adjacent said second end and the other end of which terminates at a point less than or equal to the midpoint of said anchoring member when measured from said second end of said member to said first end thereof, with said spiral groove having a flexible wire member disposed therewithin, said wire member including an outwardly projecting lip at the end thereof located adjacent said second end of said anchoring member, said anchoring member having at the first end thereof a one-way valve for communication from said first end to said second end, with said second end being provided with a groove disposed perpendicular to the longitudinal axis of said aperture and in communication with said aperture;
• b. injecting under pressure a hardenable and cementitious material through said one-way valve until said anchoring hole is substantially filled with hardenable and cementitious material;
• and
• c. permitting said hardenable and cementitious material to harden and set.
