Patent number: 9644392Abstract: A barrier cable anchor rail assembly is disclosed. The assembly is adapted to be encapsulated in a concrete column and engage a plurality of cables to provide a barrier between successive columns of concrete. The assembly includes a first rail member and a plurality of threaded connectors. The threaded connectors are adapted to be engaged by a chuck that includes cable grippers adapted to engage one of the cables. The threaded connectors can be attached to the first rail member in the same orientation with a predetermined spacing between the central axis of the plurality of threaded connectors. The first rail member maintains the orientation and predetermined spacing of the threaded connectors and provides support to the concrete column in which it is encapsulated. A barrier cable assembly adapted to form a barrier between a first concrete column and a second concrete column is also disclosed.Type: GrantFiled: October 20, 2015Date of Patent: May 9, 2017Assignee: Actuant CorporationInventor: Stanley A.

Publication number: 20150345142Abstract: A wedge for a concrete post-tension reinforcement anchorage system is shaped such that the compressive force on the tendon after tensioning of the anchorage system is substantially evenly distributed over a length of the outer surface of the tendon that is engaged by the internal surface of the wedge. The external surface of the wedge may have a first section with a first taper angle and a second section with a second taper angle, the second taper angle being larger than the first taper angle. The internal surface of the wedge may have a first section with a first taper angle and a second section with a second taper angle, the second taper angle being greater than the first taper angle. An anchor with a bore with two taper angles and tooth profiles of threading patterns on the internal surface of the wedge are also disclosed.Type: ApplicationFiled: July 28, 2015Publication date: December 3, 2015Applicant: ACTUANT CORPORATIONInventors: Thomas F.

Patent number: 8286309Abstract: In one form, the cable termination has a tubular body with an opening into which an end of the median barrier cable is inserted. A wedge gripper includes three sections for gripping the end of the median barrier cable within the tubular body. The wedge gripper has a tapering outer surface that mates with a tapered inner surface of the tubular body and has a toothed inner diameter. A threaded cap is screwed to an end of the tubular body opposite from the cable opening, such that the threaded cap forces the tapering outer surface of the wedge gripper axially against the tapered inner surface of the tubular body to force the toothed inner diameter of the wedge gripper to contract against three lobes of the median barrier cable to grip the median barrier cable.Type: GrantFiled: June 10, 2009Date of Patent: October 16, 2012Assignee: Actuant CorporationInventor: Stanley A.
