摘要： An intermediate anchor assembly includes an encapsulated anchor having a front and rear encapsulation extensions. The assembly includes a cap with an outer surface and a front tube with an inside diameter that is greater than the outer diameter of a tension member. The assembly includes a front adapter that sealingly couples to the outer surface of the cap and sealingly couples to the outer surface of the front tube. The assembly includes a rear tube having an inside diameter that is greater than the outer diameter of the tension member. The assembly includes a rear adapter that sealingly couples to the rear encapsulation extension and sealingly couples to the outer surface of the rear tube. The assembly includes a first split seal sealingly fit between the tension member and the front tube and a second split seal sealingly fit between the tension member and the rear tube.

摘要： A method and system for forming a post-tensioned concrete slab using a post-tensioning concrete anchor. The system may comprise a connector anchor including a bore that includes a first frustoconical portion, and the connector anchor may be adapted to bear on the post-tensioning concrete anchor. The system may also comprise a coupler comprising a connector and a coupler body that includes a second frustoconical portion that is oriented oppositely to the first frustoconical portion. The connector may have a bore therethrough and may be configured to receive the coupler body and to engage the connector anchor. A pocket-forming cap may releasably engage the post-tensioning concrete anchor; the pocket-forming cap may include a frustoconical wall, a gripping head, and a connector-receiving portion. The method may include using the system to form a second concrete section adjacent to a first concrete section before stressing the first concrete section.

摘要： A sheathing repair assembly for a tension member of a post-tensioning tendon, the tension member including a strand and a sheathing layer is disclosed. The sheathing repair assembly includes a repair tube having first and second end portions and a first sealing assembly. The first sealing assembly includes a first nut having a first frustoconical surface and a first forcing element adapted to cooperate with the first frustoconical surface so as to compress the first end portion of the repair tube. The sheathing repair assembly also includes a second sealing assembly having a second nut having a second frustoconical surface and a second forcing element adapted to cooperate with the second frustoconical surface so as to compress the second end portion of the repair tube.

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.

摘要： A post-tensioning tendon may include a tension member including a strand and sheath, the sheath having an outer surface. The post-tensioning tendon may also include an anchor coupled to an end of the tension member, the anchor including a tubular extension through which the tension member is passed. The tubular extension may have an engaging surface. The post-tensioning tendon may additionally include a sheathing retention assembly. The sheathing retention assembly may include an outer cap, the outer cap having a forcing surface. The outer cap may be coupled to the tubular extension. The sheathing retention assembly also may include one or more holding elements positioned at least partially within the outer cap. The one or more holding elements may each have a tapered outer surface abutting the forcing surface. The one or more holding elements each may include an inner surface that engages the outer surface of the sheath.

摘要： A pocket former includes a pocket former body and a keyway former. The pocket former is adapted to form a void in a concrete member allowing access to the stressing end of a post-tensioning tendon. The keyway former is adapted to form a keyway in the concrete to allow grout to be more securely retained in the void.
