    摘要： A system for use with a post-tensioning concrete anchor may comprise a connector anchor including a bore therethrough, the bore including a first frustoconical portion, the connector anchor adapted to bear on the post-tensioning concrete anchor, and a coupler. The coupler may comprise a coupler body including a bore therethrough, the bore including a second frustoconical portion that is oriented oppositely to the first frustoconical portion, and a connector having a bore therethrough and configured to receive the coupler body therein, the connector adapted to mechanically engage the connector anchor such that a tensioning force can be transmitted from the coupler body to the connector anchor via the connector. A method of using the system may allow a second concrete section to be poured adjacent to a first concrete section before the first concrete section has been stressed.

    摘要： An anchor assembly for a post-tensioning tendon may include a compact anchor and wedge. The compact anchor may include a wedge extension having a frustoconical inner surface. The frustoconical inner surface may have a diameter of 0.95 inches or less. The compact wedge may have a length of 1.1 inches or less. The compact anchor and compact wedge may be formed from steel having no added lead. The compact anchor and wedge may be formed by cold heading.

    摘要： A barrier cable coupler (100) for coupling two lengths of barrier cable comprises a coupler body (101) including a threaded inner surface, a first end, and a second end; a fixed retaining collar (109) having an outer surface and being retained to the first end of the coupler body, the fixed retaining collar including a tapered inner surface; one or more fixed end wedges (117) positioned within the tapered inner surface of the fixed retaining collar; a tensioning retaining collar (127) having an outer surface, the tensioning retaining collar positioned at least partially within the second end of the coupler body and including a tapered inner surface; one or more tensioning end wedges (135) positioned within the tapered inner surface of the tensioning retaining collar; and a tensioning nut (129) including a threaded outer surface engaging the threaded inner surface of the second end of the coupler body and retaining the tensioning retaining collar therein.

    摘要： A permanent stressed end cap for a post tensioned concrete member includes a grout retention feature adapted to retain a filler material within a void formed by a pocket former. The grout retention feature may be a generally knob or mushroom shaped, hex-headed, or square body extending from the cap. The grout retention feature may include one or more protrusions extending from the exterior of the cap. The grout retention feature may include one or more surface textures on the exterior of the cap.

    摘要： The process includes forming a concrete form at least one end wall where the concrete form is adapted to receive concrete placed thereinto. The process also includes setting a fixed end anchor and a tensioning end anchor on at least one end wall where the fixed end anchor and tensioning end anchor are each adapted to receive a tendon. The process further includes threading the tendon through the fixed end anchor and tensioning end anchor such that a tensioning end portion of the tendon extends from the tensioning end anchor and placing concrete into the concrete form. The process includes installing a cap about the circumference of the tensioning end portion of the tendon. The cap includes a cap body. The cap body includes an inner bore, where the inner bore has a diameter corresponding to the outer diameter of the tendon.
