Barrier connection

Abstract

A barrier connector for a concrete structure includes a base plate having a plurality of spaced apart openings. A plurality of anchor bolts is disposed through respective ones of the plurality of openings. Each of the anchor bolts has a feature at one longitudinal end extending away from a longitudinal axis of the anchor bolt. A lock nut disposed on a threaded portion of each anchor bolt on one side of the base plate. A threaded coupling is attached to the threaded portion of each anchor bolt on an opposed side of the base plate to the anchor nut, wherein the anchor bolts are affixed to the base plate without welding.

What is claimed is: 
     
         1 . A barrier connector for a concrete structure, comprising:
 a base plate having a plurality of spaced apart openings;   a plurality of anchor bolts disposed through respective ones of the plurality of openings, each of the anchor bolts having a feature at one longitudinal end extending away from a longitudinal axis of the anchor bolt;   a lock nut disposed on a threaded portion of each anchor bolt on one side of the base plate; and   a threaded coupling attached to the threaded portion of each anchor bolt on an opposed side of the base plate to the lock nut, wherein the anchor bolts are affixed to the base plate without welding.   
     
     
         2 . The barrier connector of  claim 1  wherein the features comprise at least one of L-extensions, J-extensions, corkscrews and closed eyes. 
     
     
         3 . The barrier connector of  claim 1  further comprising an adjustable anchor threadedly coupled to each of the threaded couplings, each adjustable anchor comprising a threaded connection and a gripping coupling for receiving a barrier element, the barrier element comprising at least one of a cable, a strand tendon, wire and a rod. 
     
     
         4 . A method for connecting a barrier to a concrete structure, comprising:
 placing a barrier connector in uncured concrete for the concrete structure, the barrier connector comprising a base plate having a plurality of spaced apart openings, a plurality of anchor bolts disposed through respective ones of the plurality of openings, each of the anchor bolts having a feature at one longitudinal end extending away from a longitudinal axis of the anchor bolt, a lock nut disposed on a threaded portion of each anchor bolt on one side of the base plate, and a threaded coupling attached to the threaded portion of each anchor bolt on an opposed side of the base plate to the lock nut, wherein the anchor bolts are affixed to the base plate without welding;   allowing the uncured concrete to cure;   coupling an adjustable anchor into each of the threaded couplings;   attaching a barrier element to each of the adjustable anchors; and   adjusting each of the adjustable anchors to impart a predetermined stress on each barrier element.   
     
     
         5 . The method of  claim 4  wherein the features comprise at least one of L-extensions, J-extensions, corkscrews and closed eyes. 
     
     
         6 . The method of  claim 4  wherein the barrier element comprises at least one of a cable, a strand tendon, wire and a rod.
