• WELDING BEVELS- For full penetrations, provided for greater strength, convenience and quality assurance.
• 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.

Features

When making splices between fixed points, a coupler sleeve without a center stop can be slipped entirely onto one bar and subsequently repositioned over the two bar ends being spliced.

Mechanical butt splices and connectors are available for reinforcing bar sizes No. 3 through 18 (dia. 10 through 57mm)
per BPI's Dimensions and Data charts. Transition splices are used to connect rebars of different sizes.

Mechanical lap splices are available for bar sizes No. 3 though 7 (dia. 10 through 22mm).

Headed Anchorage suitable for Grade 60 reinforcing can be created by welding Zap Structural Connectors and structural steel plates*. For simplicity, locally-sourced plate that has been cut square has a cross sectional area equal to 10-times the nominal area of reinforcing bar will be more than adequate for many applications; but other sizes and shapes of plate can be attached to suit structural demands.

Benefits

Benefits to using ZAP SCREWLOK® include positive mechanical splicing, choices for Type 1 Type 2 applications, splices for black or galvanized or epoxy coated bars, easy visual inspection, no specialized equipment, minimal clearance requirements and positive center-stop. Zap SCREWLOK® is ideal in remote areas and tight access areas; it is suitable for new construction repair or retrofit and compatible with sheared, flame-cut or saw-cut bars.

Function

Force from the screws causes rebar deformations to interlock within the coupler wedge. At the same time, the screws embed themselves into the rebar surface and then the heads TWIST OFF.

During mechanical splice assembly, as screws are tightened, they embed themselves into the rebar surface and then the heads twist off at a prescribed tightening torque. Force from the screws causes rebar deformations to interlock within the coupler wedge. The DUAL mechanical action, results in a full positive connection for transferring tension or compression forces from bar-to-bar. Screws can be tightened using suitable impact wrenches or hand-held ratchet wrenches. Linear alignment is preserved across the splice by using reinforcing bars with straight ends and securing the continuation bar in the desired position at the time of assembly.

Installation

Depending upon the size, assemble manually with socket wrench or for quickest installation, use a standard air impact wrench. By following the instructions supplied with your order, tighten the screws until the heads twist off at a prescribed value. The force from the screws causes the rebar deformations to interlock within the coupler. The screws embed themselves into the rebar surface. This dual mechanical action results in a full positive connection for transferring tension or compression force from bar-to-bar.
