JB-9 REBAR COUPLERS – BAR LOCK
Rebar couplers are used in reinforced concrete structures to replace normal Rebar lap joints. The couplers are also suitable for use in reinforced concrete columns and walls. Each rebar coupler consists of a piece of rebar equipped with thread and coupler sleeve at the right end as viewed in the direction of installation. In construction joints, Rebar Couplers can be used to replace all pieces of rebar going through the formwork.
Jb Rebar Couplers are used for joining rebars with full tension capacity. The ends of bars to be joined are provided with threads, and the bars are joined using a coupler sleeve that transfers the force on the rebar across the connection.
Types of Rebar Couplers :
Weldable couplers provide a quick and easy solution for connecting reinforcing steel bar (rebar) to structural steel sections or plates. The coupler is internally taper threaded on one end with the other end or exterior surface prepared for welding.
Steel Rebar Coupler
A Steel Rebar Coupler is used to couple or joins two pieces of steel together in the building. Steel coupler consists of a sleeve that is threaded into which the bars to be joined can be screwed into. The coupler is built as screw connection reinforcement on a framework of working joints in concrete
Tapered Thread Rebar Couplers
Tapered Thread Rebar Couplers are suitable for the majority of applications which require the joining of rebars.
They are normally supplied fitted to the end of the threaded bar and require only the engagement and tightening of the adjoining bar on site using a calibrated torque wrench.
MBT Rebar couplers
MBT Rbar Couplers require neither bar end preparation to form threads nor bar rotation to effect installation. The bars are supported within the coupler by two serrated saddles. As a series of lockshear bolts are tightened to a predetermined torque, they are embedded into the bar.
