• VERSITILITY - For attachment of reinforcing bars to liner plates, structural steel shapes or for creating headed anchorage. Shop or field weldable, before or after bar placement.
• CERTIFIED LOW CARBON STEEL - Conforms to CC-2310 (c ) material requirements of ASME Section III, Division 2. Meets chemistry AISI Grade 1018 and ASTM A 36.
• WELDING BEVELS - For full penetration, provided for greater strength, convenience and quality assurance. Suited to E7018 electrode.
• LESS WELD STRESS - Compared direct butt welds because outside diameter of structural connector is larger than the reinforcing bar so the weld area is disposed over greater length.
•
*Welder qualification, weld procedure, integrity and strength are the responsibility of others.

Features

Bar sizes No.3 through 18 (dia.10-57mm) can be spliced by this method including bars of different sizes. BPI-Grip coupling sleeves are available for use with reinforcing bars that comply to ASTM A 615, ASTM A 706, ASTM A 996, or equal.

Epoxy-coated steel reinforcing bars that comply to ASTM A 775 can be spliced by suitable cold-swaged steel coupling sleeves with shielding or removing the epoxy coating from the bar.

Hot-dipped galvanized cold-swaged steel coupling sleeves can be ordered for mechanically splicing zinc-coated (galvanized) steel bars that comply to ASTM A 767.

The cold-swaged splicing method is suitable for new construcions, field repair applicatons, and the splicing of older types of reinforcing bars, provided such bars have suitable deformations for mechanical interlock.

No special bar end preparation is required so ends can be sheared, sawed, or flame cut; however, a bar-end check is recommended. Bars can be connected from any orientation because special positioning of the press around the bar is not required. In the structure, linear alignment is preserved across the splice by using reinforcing bars with straight ends and securing the loose continuation bar in the desired position at the time of swaging.

Benefits

Cold swaging technology for mechanical splicing of reinforcing bars is one of the most established, developed, and refined splicing methods worldwide. Key to cold swaging success is it simplicity, low cost, and adaptability. There is no loss of reinforcing bar cross-sectional area at the splice location so the BPI-Grip system is a natural choice when considering the objectives of seismic design, blast resistance and safety related nuclear applications.

• Lap splices are not recommended in locations where inelastic yielding could occur because such splices are not reliable under conditions of cyclic loading into the inelastic range.

Function

BPI-Grip cold-swaged coupling sleeves consist of seamless Steel sleeves that slip over the ends of reinforcing bars.
They are deformed onto the reinforcing bar profile to produce mechanical interlock.

Mechanical interlock with reinforcing bar deformations, lugs or protrusions is the basis of swaged splice strength. The "slip test" values of swaged mechanical splices are minimal due to the tight conformation of coupling sleeves to the profile of the bar. Best of al, rue structural continuity can be established in reinforcing systems because swaged splice strengths, unlike lap splices, are not dependent upon the compressive strength or cover requirements of the surrounding concrete.

• In comparison to manual arc welding, cold swaged splices are faster to install, require a lower skill level, do not require a chemistry determination of the reinforcing bar being splices, do not require bar pre-heat or post-heat and do not require radiographic examinations.

Installation

The reinforcing bar is marked and inserted halfway into the sleeve. A hydraulic press fitted with a removable two-piece die set is used for field installation. The die set deforms the first half of the coupling sleeve in a radial direction onto the reinforcing bar in a series of overlapping pressings. The coupling sleeve is slipped over the bar in-situ and the remaining unswaged portion of the sleeve is swaged. Field-type presses, including dies, weigh between 20 and 230 lb (9 and 105 kg) and can be supported for use in any orientation.

Bench presses with adjustable stops and insertion gauges are available for shop use. These machines efficiently half-swage a coupling sleeve onto the end of a reinforcing bar before shipping. Adapter kits allow the field presses to be used in the same way.

BPI-Grip swaging equipment is easy to use and may be leased or purchase. Splicing manuals provided with equipment explain step-by-step installation and safety information.
