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 . 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.

4 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. 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 .

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.

9 Available to suit bar sizes 12mm to 50mm, the Couplers areinstalled quickly and easily on site without the need for specially trained personnel or specialised,expensive machinery. The compact design of each coupler ensures suitability for use in confinedsituations where space is restricted or where the loss of cover must be Couplers are normally supplied fitted to the end of threaded bar, requiring only theengagement and tightening of the adjoining bar on site. In order to ensure correct installation,Ancon Building Products specifies the use of a torque range of Tapered Thread Couplers is available through major rebar suppliers. Please contactAncon for further COUPLERThe Standard Tapered Thread coupler is suitable for connecting two bars of the same diameter,where one bar can be rotated.

10 It comprises an internally threaded sleeve with two right handthreads which are tapered towards the middle of the coupler . The bar ends are square cut and atapered thread is cut onto the bar. A nominal allowance of +25mm should be allowed perthreaded bar end for square cutting the bar Couplers are generally torqued onto the Reinforcing bar in the bar threading shop, the internalthreads protected by plastic end caps. The threaded ends of the continuation bar are protectedby plastic thread of the bar within the coupler is simplified by the tapered thread design which aidsalignment. When the bar is fully engaged within the coupler , the continuation bar is tightened usinga torque wrench. The Ancon Standard Tapered Thread coupler is designed to meet the requirements of BS 8110and to achieve failure loads in excess of 115% of the characteristic strength of grade 500 rebar.
