UK & Ireland Edition CI/SfB Compliant with Reinforcing Bar Couplers for the Construction Industry

Lapped joints are not always an appropriate means of connecting reinforcing bars. The use of laps can be time consuming in terms of design and installation and can lead to greater congestion within the concrete because of the increased amount of rebar used. the concrete could significantly affect the performance of the joint. The strength of a mechanical splice is independent of the concrete in which it is located and will retain its strength despite loss of cover as a result of impact damage or seismic event. Ancon couplers can simplify the design and construction of reinforced concrete...

Characteristic Strengths of High Yield Reinforcing Bar Grade Grade Grade Diameter Area B500 B500B B500C For many years the use of mechanical couplers to join reinforcing bars has been regarded as a means of reducing the use of long bars. Engineers and contractors now recognise the benefits of using couplers to accelerate the speed of construction, increase productivity and simplify design details. Sales Support Ancon’s ‘Products for Structural Concrete’ Division provides assistance for clients who require products which are used in concrete construction. These include, but are not...

Cryogenic Couplers The Ancon CTT range of tapered-thread couplers has been designed for use where cryogenic-grade reinforcing bar is being used. Typical construction projects include liquefied natural gas (LNG) and liquefied petroleum gas (LPG) storage tanks to EN 14620-3.

Reinforcing Bar Couplers Tapered Thread The Ancon range of Tapered Thread couplers is designed to suit the majority of applications which call for the joining of reinforcing bars. Available to suit bar sizes 12mm to 40mm, the couplers are installed 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 confined situations where space is restricted or where the loss of cover must be minimised. The couplers are normally supplied fitted to the end of threaded bar,...

Installation Tapered Thread Standard Series 1 The coupler is normally supplied fixed to the reinforcing bar, ready to be installed and cast in concrete. Continue to screw the bar into the coupler until tight. After casting the concrete and when ready to extend, remove the plastic end cap from the coupler. Position the continuation bar in the sleeve and rotate the bar into the coupler. To ensure correct installation, tighten the joint to the specified torque using a calibrated torque wrench on the continuation bar. Tightening torques are shown in the table opposite.

Reinforcing Bar Couplers Positional Coupler The Ancon Tapered Thread Positional coupler is designed to be used in applications in which neither bar can be rotated. Having a degree of adjustability, the Positional coupler can also be used as a closer between two fixed bars. Installation Tapered Thread Positional Series 1 The Positional coupler comprises three components, a male section, a female section and a locking nut. The male component has an internal tapered thread and an extended external parallel thread. The female component has a parallel thread and a tapered thread, both of which...

Using a torque wrench tighten the male component on the continuation bar to the specified torque, whilst holding the continuation bar with a second wrench. 5 Run the locknut along the threaded barrel of the male component to abut the female section. Using the torque wrench, tighten the locknut to the specified torque. Tightening torques are shown in the table opposite. At this point the groove in the parallel threaded section of the male component must be completely covered by the locknut. If any part of the groove is visible beyond the locknut, the degree of adjustability has been exceeded...

Reinforcing Bar Couplers Transition Coupler The Ancon Tapered Thread Transition coupler is used to join reinforcing bars of different diameters where one coupler can be rotated. With all the benefits of the Standard range, Transition couplers are designed to achieve failure loads greater than 115% of the characteristic strength of the smaller diameter grade 500 reinforcing bar. The Transition coupler comprises an internally threaded sleeve with two right hand threads both of which are tapered towards the middle of the coupler. The diameter of each thread corresponds to the appropriate bar...

Tapered Thread Weldable Couplers Ancon Tapered Thread Weldable couplers provide a convenient means of connecting reinforcing bars to structural steel plates or sections. Shorter than the standard coupler, it has a tapered thread at one end. The other end is welded directly to the steel. The couplers are manufactured from either Steel Grade 1045 to ASTM A576 or Steel Grade C45R to EN10083. The Tapered Thread Weldable coupler is suitable for welding to structural steels, Grade S275 or Grade S355. The load conditions at the connection must be determined by the designer along with the type and...

Tapered Thread Headed Anchors The Tapered Thread Headed Anchor provides an effective method of achieving rebar end anchorage within concrete. Anchorage of rebars within a concrete section is traditionally achieved by means of creating a long hooked end on the rebar. This can lead to problems when positioning the bar and can increase congestion. It can ultimately result in larger than necessary concrete sections at the location of the hooked ends. Bar Diameters 32mm and 40mm Tapered Thread Headed Anchor Dimensions Consisting of an oversized coupler, the Tapered Thread Headed Anchor...
