5 HALFEN MOMENT WHY COUPLERS? Couplers or mechanical splices have been used as a method of splicing reinforcing bars for many decades. The reasons for using them are many and varied, but it is often localised congestion that is the biggest driver. The traditional method that it replaces is that of lap splicing the reinforcing bar. However, the lap splice relies on the concrete around it to transfer the load. Poor compaction of the concrete will then compromise the load carrying capacity and this has led to a number of best practice rules including: Do not use lap splices at areas of high moment. Always stagger lap splices However, the use of a mechanical splice is superior in its load transfer to lapped splicing as it creates a direct mechanical connection between the 2 bars that is similar in its behaviour to a continuous reinforcing bar. This means that the rules put in place for lap splicing are not applicable to mechanical splices. This then frees up the contractor to use mechanical splices in areas that will improve buildability and programme times such as beam to column connections in jump-form core walls. It also leads to reduced steel volumes that reduce the weight of the structure and lessens the amount of embodied CO 2. 4

6 COUPLER COUPLER TESTING Testing performed at DNV-GL s Laboratory with the 2500kN Dynamic UTM and Video Extensometer. Photo courtesy of DNV GL Singapore Pte Ltd To ensure fitness for purpose there are a number of tests that should be carried out and a wide variety of international standards that can be tested against. The tests that are generally covered are for strength, slip, high stress/low cycle (seismic), medium stress/ medium cycle and low stress/high cycle (vibration). However, impact toughness is an important part of seismic and blast resistant solutions, so Halfen Moment goes beyond the standards to ensure absolute suitability for applications by conducting Charpy impact tests on all its products. Each engineer, should take care to ensure that the specification on the project is written in order to ensure that the correct coupler is selected. The most widely accepted international standards are: i) ISO ii) AC133 (which defines test regimes for ACI318 compliance) However, there are a number of other national standards that stipulate mechanical splice requirements, such as: IS BS NZS NF EN Halfen Moment couplers are manufactured in accordance with the highest standards of quality and conformance to ensure their suitability regardless of the in service conditions. 5

7 HALFEN MOMENT MOMENT JOINTEC The JoinTec range is our most comprehensive system with solutions for every possible application. Its main advantage over a taper thread system is that it does not require a torque wrench, making installation much simpler. SEISMIC & IMPACT & IMPACT RESISTANT Made from a Quench and Tempered machined steel, it not only provides sufficient strength to resist an equivalent bar stress of more than 700MPa, but also provides excellent impact toughness to resist blast and earthquake loads. The process to create the bar end is as follows: Saw cut the end of the bar if the bar is uneven Cold forged upset end using high pressure cylinders Cut a standard metric thread on the end of the reinforcing bar MOMENT STANDARD JT We have carried out tests to comply with static, seismic and fatigue loads, but careful selection of reinforcing bar should always be carried out to ensure that the test are valid. These tests have been carried out in many different countries and include demonstration of compliances shown in ISO ; IS , AC133, EN and BS8110 amongst others. chamfered Length Thread 45.0 º A straight parallel thread to provide an absolute bar break system where the rebar remains the weakest point.

8 COUPLER The thread on the end of the rebar can be created as Type A, B or C. Type A has a single length thread on each of the bars to be coupled. This is ideal for starter bars or short lengths of straight bars where rotation of the second bar is possible. part turn will be necessary. Therefore, this system is ideal for longer, straight, large diameter bars being installed on site. Type B Type A HALF THREAD FULL THREAD HALF THREAD HALF THREAD Type B has a double thread on one of the bars to be coupled. This facilitates the installation of the system by allowing a coupler to be screwed fully on to one of the bars. When the second bar is ready for coupling, the coupler can now be rotated off one bar and on to the other. However, to ensure a tight connection, an additional Type C has an extended thread on one of the bars to accommodate a coupler and a lock nut. The lock nut is there to eliminate the need for a part turn of the bar. It is ideal for L Bars and prefabricated bar cages where the rotation of a bar is impossible.

It is a full strength system, capable of exceeding the nominal ultimate characteristic strength of the rebar. Whilst it does limit the installation flexibility offered by the JT Type B and C, the Moment Spearline system is the slimmest of all the couplers that we offer, with the outer diameter of the coupler being only fractionally larger than the ribs of the rebar. It is a taper thread system that utilised quench and tempered machined steel to provide the slimmest profile of all our coupler systems. MOMENT SPEARLINE PLUS The Moment Spearline Plus system, uses the Spearline coupler and a radially pressed & cut tapered thread. It is a bar break system, capable of exceeding the actual ultimate characteristic strength of the rebar. The radial pressing provides sufficient strength to resist an equivalent bar stress of more than 700 MPa, and the coupler material provides excellent impact toughness. The process to create the bar end for Spearline is as follows: Saw cut the end of the bar if the bar is uneven Cut a specially formulated taper thread on the end of the reinforcing bar The process to create the bar end for Spearline Plus is as follows: Saw cut the end of the bar if the bar is uneven Cold forge the bar by radially pressing the bar to flatten the ribs Cut a specially formulated taper thread on the end of the reinforcing bar 9

It can provide exceptional performance in high cycle elastic fatigue applications, whilst maintaining values in excess of the design strengths of the bar. The Moment Rolltec system, uses the Rolltec coupler and a rolled parallel thread. It is a full strength system, capable of exceeding the nominal ultimate characteristic strength of the rebar. MOMENT ROLLTEC PLUS The Moment Rolltec Plus system, uses the Rolltec coupler and a radially pressed & rolled parallel thread. It is a bar break system, capable of exceeding the actual ultimate characteristic strength of the rebar. The bar is radially pressed prior to skimming and rolling to provide a bar break system with excellent fatigue properties that is capable of resisting an equivalent bar stress of more than 700 MPa and the coupler material provides excellent impact toughness. The process to create the bar end for Rolltec is as follows: Saw cut the end of the bar if the bar is uneven Skim the ribs to cut away the excess material and leave a smooth surface Roll a metric thread on the end of the reinforcing bar The process to create the bar end for Rolltec Plus is as follows: Saw cut the end of the bar if the bar is uneven Cold forge the bar by radially pressing the bar to flatten the ribs Skim the ribs to cut away the excess material and leave a smooth surface Roll a metric thread on the end of the reinforcing bar 10

The Ancon MBT ET range of couplers provides a cost effective method of joining reinforcing bars, particularly when the fixed bar is already in place and there is insufficient space for a hydraulic swaging press. They are easy to install and achieve failure loads higher than 110% of the characteristic yield strength of grade 500 reinforcing bar. Neither bar end preparation to form threads, nor bar rotation are required. Ancon MBT ET couplers can also be used to join imperial or metric, plain, round or deformed reinforcing bars, making it ideal for alteration or refurbishment projects. The bar ends are supported within the coupler by two serrated saddles, and as the lockshear bolts are tightened, the conical ends embed themselves into the bar. As this happens the serrated saddles bite into both the bar and the shell of the coupler. The lockshear bolts of couplers up to and including the 20mm bar can be tightened using a wrench. For larger couplers a nut runner is recommended. In all cases heavy duty sockets should be used. When the pre-determined tightening torque for the bolts is reached, the heads shear off leaving the top of the installed bolt slightly proud of the coupler. This provides an instant visual check of correct installation. Note: Impact tools must not be used to tighten lockshear bolts. MOMENT ANCON MBT ET STANDARD COUPLERS The Ancon MBT ET Standard Couplers are used to connect reinforcing bars of the same size. MOMENT ANCON MBT ET TRANSITION COUPLERS The Ancon MBT ET Transition Coupler provides an effective solution for connecting bars of different diameters. Transition couplers have all the benefits of the standard coupler and are designed to achieve failure loads higher than 110% of the characteristic yield strength of grade 500 reinforcing bar. 12

14 COUPLER MOMENT ANCON MBT ET HEADED COUPLERS The Ancon MBT ET Headed Couplers are designed to provide dead end embedment for bars in concrete. This helps to reduce congestion and simplify the placement of rebars by removing the need for hooked ends. The anchor comprises half an MBT standard coupler with a plate welded to one end which carries the full tension load of the bar when it is bearing against the concrete. The MBT Headed Coupler also has the added advantage of requiring no special bar end preparation.

Using the principles seen in the post tensioning industry, the WedgeLok coupler uses a barrel and wedge principle to grip the reinforcing bar. No bar end preparation or bar rotation is necessary. The process to create the coupled connection is as follows: Loosen the system and place one end over the end of the first rebar to be connected Using a wrench, tighten the coupler on to the first bar Insert the second rebar in to the open end of the coupler Using a wrench, tighten the coupler on to the second bar 13

When used together with Moment s proprietary 100MPa grout, the coupler system is a bar break technology and is capable of carrying very high bar loads. It has also been tested and proven to meet the seismic requirements of ISO 15835:2009 meaning that it is safe to use in Earthquake prone areas or in post disaster structures. Made from machined carbon steel, the impact resistance is much higher than traditional cast iron grout couplers. This additional behaviour also means that it can safely resist the high accelerations associated with earthquakes, explosions or other impact loads at service temperatures down as low as zero degrees. 14
