Reinforcement Couplers New_Layout 1 07/02/2017 15:41 Page 3 www.euroacc.co.uk Introduction The Terwa Parallel Threaded Coupler is a full bar strength system (the coupling is stronger than the associated rebar, sometimes referred to as a Bar Break connection) allowing a safe, reliable and efficient method of providing continuity of reinforcement through stop ends and element intersections. The adoption of a metric parallel thread on an enlarged bar diameter provides sufficient cross sectional area of material at the joint to outweigh the tensile capabilities of the equivalent diameter reinforcing bar. This attribute means the performance of the coupling at the joint can be ignored in any structural assessment, in turn this makes the adoption of the Terwa couplers over the standard detailed bars a simple exchange. The Terwa Parallel Threaded Coupler System has a full CARES Technical approval. This not only verifies the performance of the system in accordance with BS8110 and EC2 it also provides assurance that the components are manufactured and assembled in a fully audited ISO9001 facility. The female coupler (PSA) is supplied to the customer ready assembled on the reinforcing bar. The length of the bar is generally supplied as a full tension lap length in accordance with EC2, however, where the couplers are being used as a means of removing splicing laps the bars can be manufactured with any available and transportable length of reinforcing bar. There is no requirement for any threading of the corresponding male bars (TSE) as these are supplied prefabricated with the corresponding metric parallel thread. There are no specialist tools required to complete the connection, this can be carried out using a simple open jawed pipe wrench. Euro Accessories can supply a calibrated wrench to ensure the correct torque settings are achieved. Benefits 1 Full CARES Technical Approval. Simplifies shutter design. Reduces damage to formwork. Makes stripping shuttering system easier. Ideal for use in continuous pour processes utilising climbing shutters. Eliminates the need for dangerous projecting reinforcement. No drilling of shuttering materials. Reduces the congestion of rebar at laps. Lack of congestion facilitates easier concrete placement, reducing the risk of voids. No post drilling of concrete in order to epoxy resin fix continuity bars. Provides a full bar strength coupling. Connection made utilising standard metric threads. Accelerates the production process. No requirement for thread cutting or assembling of products. Full tension lap bar lengths available from stock. Fabricated components can be bolted directly to the structure using standard metric fixings. No specialist tools required. Increasing the diameter of the bar to cut the male thread. Swaging the female threaded sleeve onto the reinforcement steel.

The Position coupler is a simple method of connecting male and female bars without rotating any of the reinforcement steel. They are especially useful for connecting cranked starter bars, long lengths or large diameter reinforcement steel that can prove cumbersome to rotate or connecting prefabricated reinforcement cages in piles or columns.

Reinforcement Couplers New_Layout 1 07/02/2017 15:42 Page 8 Introduction The Alligator Couplers are used for splicing any grade or profile of reinforcing bar. These couplers are made for reinforcement steel with diameters in the range of 10mm to 40mm. Connection is made by inserting bars into both ends of the coupler. The shear bolts are then screwed by hand and tightened with either our electric or pneumatic impact wrench until bolts shear off. These couplers can be used in particular cases to replace the damaged reinforcement with full connection to the existing structure. Alligator Splicing Couplers Bar Dia.
