Anchor plate assembly

A method of mounting a coupling element cap to a post tensioning mounting plate of the type used for anchoring a post tensioning tendon to a concrete formation, comprising the steps of:

• forming said mounting plate with a mounting member of generally cylindrical construction disposed on the side of the mounting plate facing away from the concrete formation;
• forming a groove in the outer surface of said mounting member;
• forming an inwardly projecting lip within said cap;
• forming a groove in the outer surface of said cap;
• mounting said cap over said mounting member with said inwardly projecting lip of said cap engaging said groove in said mounting member;
• and
• providing a compression ring and receiving said compression ring in said groove of said cap.

An improved anchor plate assembly of the type in which a plate for placement in a concrete formation includes an aperture for a tendon to pass therethrough, a first side facing away from the concrete formation, and a second side facing the concrete formation, the improvement comprising:

• a mounting member mounted to the first side of the plate, said mounting member having an aperture sized for the passing of the tendon therethrough and aligned with the aperture in the plate, an outer surface extending from the plate, and a continuous groove in the outer surface which surrounds said mounting member;
• a cap having an open end with an interior for receiving the outer surface of said mounting member and a lip for engaging the groove of said mounting member, and with an exterior having a groove located sufficiently close to the lip of the interior region that force applied to the groove will cause pressure between the lip of the interior region and the groove of said mounting member, and having a closed end;
• and
• a ring for mounting within the groove of said cap and applying force thereon, thereby causing pressure between the lip of said cap and the groove of said mounting member.

• a ring for mounting within the groove of said tubular adaptor and applying force thereon, thereby causing pressure between the lip of said tubular adaptor and the groove of said mounting member.
