Foundation anchor and method for securing same to a foundation

A method for securing a foundation anchor to the foundation of a structure, wherein the foundation anchor comprises a plurality of elongated tension members, each of which has a free end and a fixed end, said fixed ends being secured in hardened grout embedded in foundation supporting earth, said free ends having threads formed thereon and being of sufficient length to extend through a foundation anchor hole and to be secured on one side of the foundation, comprising the steps of:

• (a) providing a first anchor plate of predetermined size, having upper and lower faces, and having holes therethrough matching in number said plurality of elongated tension members;
• (b) placing and centering said first anchor plate over a rim of said foundation anchor hole;
• (c) inserting said threaded free ends of said tension members through said holes in said first anchor plate;
• (d) threading first nuts onto said threaded free ends of a first group of tension members until pressure bearing contact is made between said first nuts and the said upper face of said first anchor plate;
• (e) continuing to thread said first nuts in pressure bearing contact with said upper face of said first anchor plate until said first group of tension members are tensioned;
• (f) providing a second anchor plate having upper and lower faces and having substantially the same dimensions as said first anchor plate, said second anchor plate having holes therethrough in equal number and diameter and alignable with said holes in said first anchor plate, and said second anchor plate having upper and lower faces;
• (g) aligning said second anchor plate over said first anchor plate;
• (h) concentrically aligning said holes in said second anchor plate with said holes in said first anchor plate;
• (i) inserting said threaded free ends of said tension members through said holes in said second anchor plate;
• (j) placing the said lower face of said second anchor plate in pressure bearing contact with said first nuts previously threaded into pressure bearing contact with said upper face of said first anchor plate;
• (k) threading second nuts onto the threaded free ends of a second group of tension members until pressure bearing contact is made between said second nuts and the said upper face of said second anchor plate;
• and
• (l) continuing to thread said second nuts into pressure bearing contact with said upper face of said second anchor plate until said second group of tension members are tensioned.
