Rebar Couplers

The rebar couplers manufactured and supplied by Steeledge Steel Scaffolding LLC has earned international acclaim, thanks to the string of superior virtues displayed by them. We have already earned an unassailable reputation as trustworthy Manufacturers, Suppliers and Exporters of Rebar Couplers in Dubai (UAE) and are fast leaving our mark in the international arena as well.

SALIENT FEATURES

And what exactly are the merits of our couplers that we are talking about? Here’s a look!
  • Superior functionality
  • Long life
  • Thoroughly tested for quality (before delivery)
  • Backed by enviable technical competence
  • Customized as per client requirements
  • Procured from very high quality raw material

Rebar Splicing Couplers are available in two types :

  • Taper Thread Technology
  • Parallel Roll Thread Technology

INTRODUCTION OF REBAR COUPLER :

The traditional method of connecting reinforcement bars with lap joints continuity in reinforced concerete need not be always appropriate. Advantages of simplicity and economy in lap splicing is limited to smaller diameter bars, Taper Mechanical Couplers offer the solution for splicing when large diameter bars are involved.

TECHNICALLY SUPERIOR :

Spliced rebar performs like continuous reinforcement. Splicing develops strength mechanically, independent of concrete. Therefore provides ductility in RCC structures independent of condition of concrete. Proven cyclic performance of spliced rebar offers strength during man-made, seismic or other natural events. The continuity of spliced rebar offers excellent provision for grounding electrical current.

Unique Features :

  • Overall diameter reduces need for additional concrete cover
  • Re-Bar Splicing couplers are designed to with stand a breaking load of at least 700 N/mm2
  • Works like a continous bar when installed, no cranking required
  • Taper thead connections offers easy alignment, achieve full tightness with merly 4-5 turns
  • No lock nuts required.
  • Cross threading prevented.
  • No special tools for installation
  • Inspection of splice made easy with torque wrench
  • STEELEDGE Rebar Splicing Coupler, the universally approved product is desgined to cater for almost every conceivable application for joining of reinforcing bars. The taper thread syste provides easy alignment for engagement of the incoming rotating bar and develop full strength when hand tightened.
  • STEELEDGE Rebar Splicing Coupler consists of a High Tensile Carbon Steel Sleeve with identical threads at opposing ends tapering towards the middle.
  • Bar ends shall be square cut and taper threaded accordingly for connection. Both couplers and threaded bards are supplied with protective plastic caps.
  • STEELEDGE Rebar Splicing Coupler are usually located in RC Structures such as long columns, inclined columns long beams, cantilevered structures.

TAPERED THREAD :

The Tapered Thread coupler is designed to suit the majority of applications which require the joining of reinforcing bars. The ends of the rebar are cut square and a tapered thread is cut onto the bar to suit the tapered thread coupler. The sleeve is tightened onto the threaded bar end using a calibrated torque wrench. Rebar Splicing Couiplers are Taper threaded couplers with strength equivualent to the specified tensile strength of the rebars. Every installation, no forging or upseting of rebars required to achieve bar break. Slim size helps in reducing congestion.

TAPER THREAD TECHNOLOGY COUPLERS :

Taper Couplers are designed to splice the reinforcement bars where at least one of the bars could be rotated. The Taper Threaded design of Coupler helps easy engagement of the bar within the coupler with simple alignment. The standard Taper Threaded Coupler comprises of interally threaded sleeves with two right handed threads tapering mid length of coupler. The bar end to be spliced are saw-cut and taper threading is provided on bar ends with branded threading equipment and thread cutting devices. The bars are connected internally by hand tighting and then with Pipe Wrench [Torque Wrench may be preferred].

STEELEDGE Mechanical Splices are a taper-threaded splicing system that assures a positive locking connection, providing continuity and structural integrity to reinforced concrete construction. STEELEDGE spliced bars behave as continuous lengths of reinforcing steel bars by providing “full strength” in tension, compression and stress reversal applications.

The company offers the most accepted Taper Threaded Rebar Splicing System for meeting the diverse requirements of construction Projects. Our Taper Threaded Rebar Splicing System is designed specifically for ensuring efficient performance.

FEATURES :

  • Allows maximum bar cross-section to be used
  • Smallest diameter in the industry reduces need for concrete cover and eliminates rebar congestion
  • Short length and slim design ensure the least disturbance to uniform stiffness
  • Splice strength is independent of rebar deformation
  • Unique tapered thread requires no lock nuts and provides a positive locking, no-slip connection
  • Any length, shape, diameter or combination of bar sizes can be mechanically spliced.

INSTALLATION BENEFITS :

  • Takes approximately four turns to engage
  • Prevents cross-threading
  • Fastest system to install
  • No special tools or skills required
  • No power required for installation
  • Splice inspection is quick and easy
  • Reduces crane time
  • Bar threader is easy to use and can be set up on-site or at the fabricator
  • Because most of the work is done in the fabrication shop, construction schedules are accelerated
  • APPLICATION AREAS : Piles, Foundations, Columns,Beams

PRODUCT FEATURES :

This is a rolled-parallel threaded mechanical splicing system designed for the connection of concrete reinforcing bars 16 to 40 mm. STEELEDGE Couplers comply with ACI 318, IBC 2006, BS 8110, Eurocode 2, DIN 1045, CalTrans, ASME Sec III Div 2.

Benefits :

  • Simple process
  • Fast cycle time : less than 30 seconds per thread!
  • One standard coupler for all splicing requirements
  • Easy installation
  • Shortens construction cycle times
  • Manufactured under strict quality assurance plan.
