Technically Superior: NCT rebar Couplers performs like continuous reinforcement, develops strength mechanically, independent of concrete. Therefore provides ductility in RCC structures independent of condition of concrete. Proven cyclic performance of rebar offers strength during man-made, seismic or other natural events. The continuity of rebar offers excellent provision for grounding electrical current.
Designer friendly & Cost Effective:
NCT RE-BAR couplers reduce rebar congestion and improve concrete flow & consolidation. Offer greater flexibility in design options. The simplicity in detailing of reinforcement, particularly in reinforcement congestion zones minimizes the reinforcement fixing errors, detailing and fixing of seismic reinforcement becomes effortless. Workability with higher steel-to-concrete ratio allows optimum sizing of RCC structural members.
NCT RE-BAR couplers increase production rates because of reduced installation time and simpler quality control requirements. Because of these differences, labour requirements and costs will be substantially reduced.
NCT Re-BAR coupler offers quality, cost and time saving. Fixing couplers requires no special skills or equipments. Simple mechanical ways in adopting mechanical splicing compared to lapping accelerates construction schedules for optimum cost and efficiency.
Handling the rebar in convenient sizes saves on valuable crane time. It is economical to use couplers for higher diameter rebar as it saves on considerable weight and rebar wastage. Special application for micro-piling, piling, slope protection, pre-cast concrete, slip-forming, formwork protection; top-down construction makes NCT coupler as a part of any major project.
NCT Standard Couplers are designed to join the reinforcement bars where at least one of the bars could be rotated. The threaded design of coupler helps easy engagement of the bar within the coupler with simple alignment.
The standard threaded coupler comprises of internally threaded sleeve with two right handed threads tapering mid length of coupler. The bar ends to be joined are saw cut and threading is provided on bar ends with proprietary branded threading equipment and thread cutting devices. The bars are connected initially by hand tightening and then with pipe wrench (torque wrench may be preferred)
The Re-BAR system provides butt joint when the bar threading is fully engaged with coupler by appropriate tightening. The Re-BAR Joining complies with BS-8110 Part 1, 1989 & BS-5400 Part 4, 1990 andACI-318.
The NCT re-bar couplers are supplied with internal thread protection plastic cap; The compact design of coupler ensures that no extra concrete cover is demanded for coupler protection.
