Rebar connection, anchorage and termination solutions for control towers, supporting structures and car parks
We make it easier to achieve full strength for your reinforced concrete application, from airport control towers and supporting infrastructure to parking decks and car parks.
A Better Way
Mechanical couplers―typically threaded connections―are the preferred method for connecting reinforcing bars due to their efficiency in providing load path continuity through rebar, as well as the steel savings that result due to the elimination of overlap in bars.
nVent LENTON couplers are trusted to help ensure a positive locking connection and improve structural integrity in reinforced concrete slabs, beams and other building foundational elements. For tower and deck construction, nVent LENTON spliced bars behave as continuous lengths of reinforcing bar by providing “full strength” in tension, compression and stress reversal applications.
A critical aspect of extracting maximum value from your airfield concrete reinforcement project is having an efficient, reliable method of connecting, anchoring and terminating rebar in precast and cast-in-place concrete forms. Compared to lap splicing, mechanical splicing provides more advantages that can streamline your project timeline and budget.
Lap vs. Mechanical Splices
The benefits add up when you choose mechanical splicing connections for building reinforced concrete structures.
Lap Splices
- Tend to have poor cyclic performance. To prevent concrete splitting, additional rebar may be required for confinement.
- Present design constraints. Lap splices double the number of bars leading to rebar congestion, which can restrict the flow of aggregates.
- Have hidden costs. Lap splicing can involve time-consuming calculations and overestimating mistakes.
Mechanical splices:
- Are proven reliable. Mechanical splices behave similarly to a continuous piece of rebar and offer superior cyclic performance.
- Are design friendly. Reducing rebar congestion and improving concrete consolidation are easier with mechanical splices.
- Are economical. Mechanical splices require no special skills and reduce labor and material costs because less rebar is used.
