Retaining Walls

This type of splice can resist compression stress merely. The compressive stress is transferred by vertical bearing from one bar to another one. Compression only mechanical splices can be used when tension stress does not occur.

Coupler for Thread-Deformed Bar-

This type of deformed bars comes with special bars with thread-like rolled deformations. These are assembled with lock nuts and threaded couplers, then the nuts are tightened to the specified torque.

Upset Straight Thread Coupler-

This type of coupler is used to produce a full-length mechanical joint between reinforcing bars with upsetting ends. It can connect rebars of the same or different diameters laterally, vertically and slantingly. The coupler consists of a coupler with internal straight threads at each end that joins two upset end reinforcing bars with matching external threads.

Non- upset thread Coupler-

The $4 million project was successfully completed in two separate phases with both phases coming in on schedule and the overall costs coming in under budget. Emergency repairs to the facility were completed on December 11th, 2014 which allowed for the facility to operate through the critical winter months. Permanent electrical repairs along with less critical site deficiencies were completed in April and May of 2016 when a longer facility shut-down could be tolerated. In order to meet the required schedule, TransGas delegated procurement and construction management services to WSP.

Cold-Swaged Threaded Coupler-

This type of sleeve is used for the connection of ribbed rebar. It is made of carbon structural steel and can connect reinforcing bars with a diameter of 16 to 40 mm. The sleeve uses a hydraulic swaging press with a special dye to deform the sleeve around the ends of the spliced reinforcing bars. This produces a positive mechanical interlock with the reinforcing bars.

Taper-Threaded Coupler-

This type of coupler is designed for applications that require the joining of reinforcing bars. The compact design of each coupler ensures suitability for use in confined situations where space is restricted or where the loss of cover must be minimised. The couplers are normally supplied fitted to the end of the threaded bar, requiring only the engagement and tightening of the adjoining bar on site.

Straight Threaded Coupler with Upset Rebar Ends-

This type of coupler consists of forming heads on the ends of the bars that are connected using a hydraulic machine. It is designed to fit between closely-spaced bars. 

Grout-Filled Coupling Sleeve-

The $4 million projThis type of sleeve is filled with grout that provides a mechanical bond between rebar deformations and grooves on the inside of the sleeve. This is filled with a cement-based, non-shrink, high-early strength grout. The range comprises two standard coupler types: Full-grout sleeves and Half-grout sleeves. ect was successfully completed in two separate phases with both phases coming in on schedule and the overall costs coming in under budget. Emergency repairs to the facility were completed on December 11th, 2014 which allowed for the facility to operate through the critical winter months. Permanent electrical repairs along with less critical site deficiencies were completed in April and May of 2016 when a longer facility shut-down could be tolerated. In order to meet the required schedule, TransGas delegated procurement and construction management services to WSP.

Combo Grout-Filled/Threaded Sleeve–

This type of sleeve is designed for the connection of precast elements. Each sleeve features a threaded end that is used for the connection to reinforcement at the precast element and a wide cavity to perform a grout connection at site. The wide mouth opening of the sleeve allows for minor bar misalignment during erection. The wide mouth also allows for transitioning between different bar sizes.

Metal-filled coupling Sleeve-

This type of sleeve is placed end to end in the metal sleeve with a molten metal filler in the tap hole. The filler material flows between the bars and the sleeve, solidifying in the deformations of the rebar and the internal ribs of the sleeve, forming a mechanical interlock.  

Cold-Swaged Coupling Sleeve-

This type of sleeve is used for the connection of ribbed rebar. It is made of carbon structural steel and can connect reinforcing bars with a diameter of 16 to 40 mm. The sleeve uses a hydraulic swaging press with a special dye to deform the sleeve around the ends of the spliced reinforcing bars. This produces a positive mechanical interlock with the reinforcing bars.

Shear Screw Coupling Sleeve-

This type of sleeve consists of a coupling sleeve with shear head screws which are designed to shear off at a specified torque. 

Extruded Coupling Sleeve-

This is a cold extruding coupling sleeve that connects two reinforcing bars by extruding a coupler onto the reinforcing bars.  

Coupling Sleeve with Double Wedge-

This type of sleeve is made of a ductile iron sleeve that consists of two internal wedges. Two series of cone-pointed screws are arranged along the sleeve length.

Upset Straight Thread Coupler-

This type of coupler is used to produce a full-length mechanical joint between reinforcing bars with upsetting ends. It can connect rebars of the same or different diameters laterally, vertically and slantingly. The coupler consists of a coupler with internal straight threads at each end that joins two upset end reinforcing bars with matching external threads.

Coupling Sleeve with Shear Bolt/Wedge-

This type of sleeve is designed to deliver a quick and simple method of splicing of 12 mm – 20 mm bar. Installation is made in seconds by overlapping the rebar in the steel sleeve and driving the wedge pin between the bars with a portable hydraulic hand tool. The coupling sleeve is oval in cross-section permitting the overlapping of two reinforcing bars of the same diameter in the sleeve.

Dowel Bar Mechanical Splice-

This is a two-piece, upsized parallel threaded, mechanical splice that eliminates protruding dowels. No welding or machining is required for the installation of this splice and the threading operation does not reduce the nominal cross-sectional area of the bar.

Compression-only Mechanical Splice–

This type of splice can resist compression stress merely. The compressive stress is transferred by vertical bearing from one bar to another one. Compression only mechanical splices can be used when tension stress does not occur.
