Applications
FIELD SPLICE OPTIONS FOR YOUR PROJECTS
BPI STANDARD BARSPLICER
COUPLER WITH STANDARD NATIOINAL COARSE THREADS AND FLANGE
• PRE-FABRICATED SETTING AND SPLICE BARS - Made to your dimensions, straight, hooked 90- 180°, single or double-ended connections and other configurations.
• STANDARD GRADE 60 REINFORCING BARS - Each heat lot from BPI is controlled, tested and certified, ASTM A 615 black deformed or ASTM A 775 epoxy coated reinforcing bars.
• DOWEL BAR REPLACEMENT - No drilling holes through forms - No protruding rebar when concrete is poured. Continuity across construction joint is established upon engaging spice bar..
• AASHTO Standard Specifications for Highway Bridges - Meets the full mechanical connection requirements of 8.32.2.3 (17th Ed) for 125% x specified yield Grade 60.
• DOT PROJECTS and COMMERCIAL APPLICATIONS - Bridge decks, piers, ramps, walls, mats, tanks, parking garages - where specifications are 125% x specified yield Grade 60. .
• ACI 318 Chapter 12 FULL MECHANICAL SPLICE - Standard BPI Barsplicers are pre-tested to develop at least 1.25 fy of the bar. For Xtra Performance, use the Barsplicer XP series.
BPI BARSPLICER POSITION
COUPLER WITH STANDARD NATIONAL COARSE THREADS
• NO ROTATION OF BARS - Assembly is completed in the field by unwindling a pre-assembled coupler from a long thread on the splice bar onto the adjoining thread on the setting bar..
• OPTIONAL LOCK NUT - To lock a pre-bent splice bar in a specific alignment or a specific orientation after engaging a position coupler onto the setting bar. (Extra thread length required).
• CONVENIENCE - position Couplers and optional lock nuts are pre-assembled to splice bars that have been fabricated to your dimensions. This results in saved-time in the field.
• GRADE 60 REINFORCING - Bars used for setting and positional splice bars are controlled and certified, ASTM A 615 black deformed or ASTM A 775 epoxy coated reinforcing bars.
• 125% x SPECIFIED YIELD - Position couplers are designed to meet the mechanical splice requirements of ACI 318 Chapter 12 and most DOT requirements for mechanical splice strength.
• SPECIALTY APPLICATIONS - When steel congestion is a problem and splice bars cannot be rotated to engage the threads, or when bar lengths are long and impractical to rotate.
BPI STRUCTURAL CONNECTOR
WELDABLE CONNECTOR WITH STANDARD NATIONAL COARSE THREADS
• STRENGTH RATING - Has capacity to exceed a minimum joint strength of 75,000 psi measured in the rebar; equal to 1.25 fy Grade 60.*.
• COMPATIBILITY - Black reinforcing bars ASTM A 615 grade 60 or epoxy coated ASTM A 775 Grade 60 from Barsplice Products, Inc. with threaded ends. .
• VERSATILITY - For attachment of reinforcing bars with threaded ends to plates, structural steel shapes or for creating headed anchorage. Shop or field weldable, before or after bar placement..
• CERTIFIED LOW CARBON STEEL - meets chemistry AISI Grade 1018 and ASTM A 36. Suited to E7018 electrode.
• WELDING BEVELS - For full penetration, provided for greater strength, convenience and quality assurance.
• LESS WELD STRESS - Compared to 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.
BPI BARSPLICER DoughNUTTM
NATIONAL COARSE THREADED BAR HEADED ANCHORAGE
• HEAD REINFORCING BAR MECHANICAL ANCHORAGE - Reduces development length of bars by transmitting a proportion of force from bar to bar to concrete via head bearing area.
• ACI 318 MECHANICAL ANCHORAGE - In accordance with section 12.6, BPI Barsplicer DoughNUTs develop at least the strength of the bar, fy Grade 60. In air tests exceed 1.25 fy Gr.60..
• HEAD VERSUS HOOK - while hook bars reduce development length compared to straight, they might bring about congestion. Doughnut's alleviate this problem and facilitate bar placement..
• APPLICATIONS - Replaces hook bars in beam-column joints, knee joints, pile caps and column roof slab connections. Replaces stirrup bars as confinement steel.
• BENEFITS - Preinstalled on Grade 60 by means of standard threads - saves field labor. Easy placement - no special bend directions, minimal detailing, saves space, more design flexibility.
• HEAD AREA - 5Ab full cross-sectional area with at least 4Ab projected bearing area in tension (Ab = area of reinforcement). Minimum recommended anchorage length = 12 db** (db = bar dia)/

Features
BPI® BARSPLICER setting and splice bars can be fabricatedto almost any shape...and BPI's small compact threaded couplers allow the system to be used in tight spaces such as walls, traffic barriers, corbels, and slabs. For DOT projects, BPI can supply you fully certified epoxy coated bars and couplers, threaded, processed and tested in accordance with BPI's quality system ISO 9001:2000.
Benefits
BPI® BARSPLICER dowel bar replacements have the advantage of permitting continuity of reinforcement across construction joints without formwork penetration. Because flanged couplers are typically fully embedded in concrete, their use eliminates projecting bars, thereby relieving constructability problems.
BPI SETTING BARS and SPLICE BARS are supplied to your dimensional specifications, straight or bent or can be headed with a Barsplicer DougNUTTM. When fully assembled, splices across construction joints achieve the full tension-compression requirements of ACI 318 Chapter 12.
Flanged couplers used on setting bars have holes that permit nailing them to the sides or ends of the formwork. BPI Barsplicer couplers have internal threads that permit the attachment of dowel splice bars or long lengths of reinforcing bar. These couplers are made from steel conforming to ASTM A 108. Although mostly used for splicing reinforcing bars to dowel splice bars, nothing precludes their use as standard tension-compression mechanical splices.
Bar sizes No. 4 though 11 (No. 12 through 36) Grade 60 (420) can be spliced by the BPI® Barsplicer method. The system uses standard Unified American national coarse threads - the same as those utilized in the familiar nuts and bolts you know and trust. Threaded couplers are used with bars that have matching exterior threads cut or rolled directly onto the ends of the reinforcing bars. There is no requirement for pre-forging or for a bar end upsizing operation so the system is simple and highly cost-effective. The thread length on the bars is controlled by BPI to ensure proper thread engagement. Precautions are taken BPI to protect the threaded ends of the bars during shipping and handling.
Function
Dowel bars at construction joints transfer tension and compression loads between reinforcing bars on both sides of the joint. A common headache for contractors and placers is that one - piece bars projecting from the concrete get damaged, interfer with other construction activities and can be a cause of accidents

Installation
In the field, reinforcing bars are cast in concrete with the flanged coupler attached to the form face. After the formwork is removed, straight or bent splice bars are installed into the coupler to extend the reinforcing bar. A simple pipe wrench can be used to snug and secure the splice assembly. No torque wrench is required for this operation.
