Taper Threaded Rebar Splicing Systems

- For many years, the traditional method of connecting reinforcing bars has been with lap splicing. But as many structural engineers, - I= architects andspecifien have discovered, lap splicing has very few advantages and quite a few disadvantages when compared to mechanical splicing. Read through the following pages and -I--- - --- u explore the reasons why you should consider mechanical couplers.

Lap splices depend on concrete for strength, and therefore lack structural integrity and continuity in concrete con5truct;on. J

LENTON mechanical splice - ideal balance of steel and concrete. rebar in the lap zone

Provides ConIinuitV in Economy of Design LENTON improves steel-to-concrete ratio by eliminating half of the bars necessary in the "lap zone" of a column. Use of lap splicing may exceed the concrete to steel ratio of many international standards.

With LENTON splices, you can design smaller columns and create maximum floor space, while reducing your form costs. Form sizes can also be established for more cost savings, and LENTON couplers are excellent for future extension applications.

LENTON taper threaded couplers are manufactured from htgh strength, htgh qualiTy steel. All ERICQe design and manufacturing facilities are I S 0 9001 -2000 registered.

Seismic Considerations Lap spltces may pull apart during seismic loads. LENTON couplers offer more strength than lap splices during sa~srnic, man-made blasts or other natural events as their uerformance is indeoendent of surrounding concret'e. LENTON c~u~lers'exceed AClmNBCIICC* Type I & Type 2 requirements.

LENTON splices prov~de you with the ability to design and build concrete struc- tures that meet or exceed today's strrngent constructton codes and federal reg- ulations regarding selsmic frame constructton. LENTON couplers are superior to other current methods of sulicin~ in withstandins setsmic, man-made blasts and other natural events by proidtng reinforcingspl~ces for rebar.

Test Conducted to ICC AC 133 Performed on Typical U.S. Rebar

LENTON provides superior performance in cyclic reversal appI~caf!ans

Provides Eontinuih! in Project Economics LENTON reduces the amount of additional rebar that is required in a lap syster- The system can be installed in a matter of seconds, with no special skills or bulky equipment required. Construction schedules can be accelerated to achieve optimum costs. The benefit-to-cost ratio using the LENTON system is often superior t o lap splicing.

Corrosion Considerations Corrosion increases the size of the rebar causing the concrete cover t o spall and crack. As lap splices depend on the "bond" between concrete and steel for strength, concrete degradation caused by corrosion results in lap splice failure. With LENTON couplers, structural integrity is maintained even with the loss of the concrete cover because mechanical couplers perform similar t o a continuous piece of rebar.

Lap splices transfer their load through the concrete and will fail as concrete cover degrades.

LENTON mechanical couplers perform amilar to a continuous length of rebar regardless of concrete cond~tion

LENTW Taper Threaded Mechanical Rebar Splidng System Provides:

A better way to design and build Continuity and structural integrity Compliance with international design codes Ease of installation Economy of design Many economic advantages Reduced shipping costs over other methods of splicing or anchoring Exceed Type 1 & Type 2 splice requiremen6

P8 and PI3 style couplers are designed to quickly splice two curved, bent, or straight bars, when neither bar can be rotated, and where the ongoing bar is restricted in its axial direction. Typical applications for these couplers are for the splicing of prefabricated cages.

The PI3 position coupler can be supplied in two pieces for application against form work. The female parallel thread is corrosion protected with a plastic screw-in pro- tection cap.

While all LENTON mechanical splices can be easily tightened with a standard pipe wrench in 4 t o 4-112 turns, ERICO' also supplies adjustable inspection wrenches. This wrench can be used to both install couplers and inspect torque values after installation.

Our recommended inspect~on wrench is engineered t o provide values of torque enabl~ng you t o achieve the best poss~ble splice.

The inspection wrench is intended for use on ALL types and styles of LENTON taper threaded couplers/products. This includes LENTON' FORM SAVER, LENTON TERMINATOR, LENTON Position Couplers and LENTON Half Couplers.
