1 ReinforcingBar Couplersfor the Construction IndustryCI/SfB(29)Et6 March 200722 Ancon designs and manufactures high integrity steel products forthe construction industry. Through continuous programmes ofnew product development, inward investment and employeeadvancement, the company is committed to maintaining thehighest level of customer service within a dynamic andchallenging many years the use of mechanicalcouplers to join Reinforcing bars has beenregarded as a means of reducing the use oflong bars.

The strength of a mechanical splice isindependent of the concrete in which it islocated and will retain its strength despite lossof cover as a result of impact damage orseismic Ancon range of Reinforcing bar Couplers isthe most comprehensive available andincludes tapered threaded, parallel threadedand mechanically bolted Couplers .

6 Ancon Reinforcing bar Couplers are availablethrough major rebar stockists and ThreadThe Tapered Thread coupler is designed to suitthe majority of applications which require thejoining of Reinforcing bars. The ends of the rebar are cut square and a tapered thread is cutonto the bar to suit the tapered thread sleeve is tightened onto the threaded barend using a calibrated torque Couplers are suitable where it is notconvenient to have the bar ends prepared forBartec, or tapered thread Couplers . The barsare supported within the coupler on twoserrated saddles.

7 Bars are locked in place by aseries of special lockshear bolts, the heads ofwhich shear off when the predeterminedtightening torque is reached, providing a visualcheck of correct Bartec system is one of the smallest andthe most cost-effective coupler systems in ourrange, when used on large scale, high couplervolume projects. The ends of the bars areenlarged and a parallel thread is cut onto theends to suit the threaded coupler . The coupleris assembled using a pipe or chain wrenches are not SELECTION All Ancon Couplers are designed to exceedthe tensile strength for Reinforcing bars toBS4449: four types of Ancon Reinforcing barcouplers require different fixing methods.

8 This,together with the quantity to be fixed and thelocation, will determine which is the mostappropriate coupler for a particular X-LBar X-L Couplers provide a cost-effective, fullstrength joint and are the smallest Couplers in the Ancon range. They are particularlyappropriate for applications where fatigue is anissue. The ends of the bars are cut square andmarginally enlarged. A parallel thread is thenrolled onto the ends to suit the threadedsleeve. The coupler is installed using a pipe orchain wrench.
