摘要： A sealing connector cover for a tendon in an encapsulated post-tensioning reinforcement system includes a plurality of circumferential cover segments each comprising a circumferential part of a female connector housing at one longitudinal end, and a male connector housing at another longitudinal end. Each segment has a locking element to engage a corresponding locking element on a longitudinally corresponding segment. Each circumferential segment comprises a circumferential part of a locking element in the female connector housing configured to engage the male connector housing of a longitudinally adjacent sealing connector cover or a connector on an encapsulated anchor.

摘要： A pre-compression system for pre-compressing a concrete structure, the system comprising a first tubular element (31) that is expandable in a longitudinal direction and interposed between the first and the second head (21, 22). The first tubular element (31) is movable between a longitudinally elongated configuration, in which a pressurized fluid is placed inside the first tubular element (31), and a contracted configuration, in which said fluid is at least partly removed, the passage from the elongated configuration to the contracted configuration bringing about a compression on the concrete which at least partly envelops the first tubular element (31).

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.

In some aspects, a duct coupling device includes a hollow body, at least one coupler seal disposed about an outer surface of the body, and a plurality of apertures extending through the body for facilitating the passage of a fluid and/or any other medium therethrough. A duct coupling system includes a duct coupling device with a sealing member, coupler transitions adapted to receive the duct coupling device, and a sealing member. The sealing member is configured to seal an annular space disposed between a first surface of the duct coupling device and a surface of one of the first and second ducts. A method of coupling ducts includes providing a first coupler transition on a first duct, providing a second coupler transition on a second duct, and providing a duct coupling device between the first and second coupler transitions.

摘要： An embodiment is directed to a duct coupler for joining two segments of conduit. The duct coupler includes a coupler body. The coupler body is generally tubular and has an inner diameter generally corresponding to the outer diameter of a section of conduit measured at an annular locking rib positioned on the section of conduit. The duct coupler further includes one or more protrusions formed on the interior surface of the coupler body. Each protrusion is generally wedge shaped. The one or more protrusions are positioned to engage with at least one annular locking rib to retain the section of conduit within the coupler body. The duct coupler further includes a body gasket. The body gasket is generally tubular and positioned on the interior surface of the coupler body. The body gasket is positioned to form a seal between the inner wall of the coupler body and the outer wall of the section of conduit.

摘要： A coupler apparatus for use with precast concrete segmental construction having a first duct, a first coupler member extending over and around the first duct, a second duct, a second coupler member extending over and around the second duct and a gasket received at the ends of the first and second coupler members so as to prevent liquid from passing between the coupler members into an interior of either of the ducts. The ducts extend at a non-transverse acute angle with respect to the ends of the coupler members. Heat shrink seals are affixed to the opposite ends of the coupler member so as to secure the coupler members to the ducts in liquid-tight relationship. The ends of the coupler member have generally V-shaped grooves facing each other. The gasket is received in compressive relationship within the V-shaped grooves.

摘要： A coupler apparatus for use with ducts is used on a multi-strand post-tensioning system. The coupler includes a tubular body with an interior passageway between a first open end and a second open end. A shoulder is formed within the tubular body between the open ends. A seal is connected to the shoulder so as to form a liquid-tight seal with a duct received within one of the open ends. A compression device is hingedly connected to the tubular body for urging the duct into compressive contact with the seal. The compression device has a portion extending exterior of the tubular body. The compression device includes an arm with an end hingedly connected to the tubular body and having an abutment surface adjacent the end. The arm is movable between a first position extending outwardly of an exterior of the tubular body and a second position aligned with an exterior surface of the tubular body. A latching member is connected to an opposite end of the arm to affixing the arm in the second position. The abutment surface of the arm serves to push a corrugation of the duct against the seal and against the shoulder so as to form a liquid-tight seal between the duct and the interior of the coupler.
