1 DIVISION: 03 CONCRETE Section: Reinforcing Steel REPORT HOLDER: HEADED REINFORCEMENT CORP CONDOR AVE. FOUNTAIN VALLEY, CA (800) HRC EVALUATION SUBJECT: XTENDER HRC 500/510 POSITIONAL COUPLERS 1.0 EVALUATION SCOPE 1.1 Compliance with the following codes! 2006 International Building Code (IBC)! 2006 International Residential Code (IRC)! 2003 International Building Code (IBC)! 2003 International Residential Code (IRC) 1.2 Evaluated in accordance with! ICC AC 133, Effective June Properties evaluated! Structural 2.0 USES The Xtender HRC 500/510 positional couplers are mechanical couplers used for splicing deformed, uncoated steel reinforcing bars for the purpose of resisting tensile and compressive forces in reinforced concrete structural members. The Xtender HRC 500/510 system complies with the requirements of ACI section for use as a tension and compression Type 1 or Type 2 mechanical splice of deformed steel reinforcing bar as defined in ACI 318 Section DESCRIPTION 3.1 General Xtender HRC 500/510 positional coupler assembly and dimensions are shown in Table 1. The minimum upset head dimensions can be found in Table 2. The angle of the upset head is 30 from the longitudinal axis of the steel reinforcing bar. ASTM A706 grade 60 reinforcement is permitted in bar sizes No.: 4, 5, 6, 7, 8, 9, 10, 11 and 14. ASTM A615 grade 40 and 60 reinforcement is permitted in bar sizes No.: 4, 5, 6, 7, 8, 9, 10, 11 and 14. ASTM A615 grade 75 reinforcement is permitted in sizes No.: 8, 11, and Materials The Xtender HRC 500/510 position couplers are manufactured from steel complying with ASTM A grade 1141 or equivalent for reinforcement size No. 4 through No The steel reinforcing bar shall be of material designated by ASTM A706 Grade 60, or ASTM A615 Grade 75, Grade 60, or Grade INSTALLATION 4.1 General The HRC couplers are to be installed in accordance with the applicable code, this evaluation report, and HRC s installation instructions. Installation instructions are supplied with the product and are available on HRC s website ( Splice locations must comply with applicable code requirements and be noted on plans approved by the code official. All required distances, spacing, and coverage should be per applicable code. Cover shall be measured from the outside of the connecting device. Fabricators, fabrication facilities, and field installers shall be qualified and approved to the specifications of HRC.

2 4.2 Approved Fabricators Specially prepared ends of reinforcing bars shall be prepared in either the report applicant s facility or the facility of a fabricator approved by the code official per IBC section and HRC. The fabricator shall provide test data to the satisfaction of the code official for each coupler model, type, and steel reinforcing bar size: The fabricator prepares the ends of the steel reinforcing bar as required by HRC in a manner consistent with the requirements of this evaluation report and the qualifying test specimens The method of preparing the reinforcing bars ends is shown in attachment Type 2 splice: for Type 2 connections under the IBC each steel reinforcing bars tested in static tension shall develop 100 percent of the specified tensile strength of the steel reinforcing bar and 125 percent of the specified yield strength of the reinforcing bar Type 1 splice: for type 1 connection under the IBC each steel reinforcing bar shall be tested in static tension and develop 125 percent of the specified yield strength of the reinforcing bar. 4.3 Field Fabrication Where the ends of the reinforcing bars are prepared at the jobsite, the testing laboratory shall witness the portions of the preparation and assembly of the test specimens representing the field applications. Additionally: The jobsite fabricator must be approved by HRC For each reinforcing bar size the jobsite fabricator must demonstrate the following items to the satisfaction of the special inspector: The fabricator prepares the ends of the steel reinforcing bar as required by the evaluation report applicant in a manner consistent with the qualifying test specimens See attachment 1 for the detailed description of the method of preparing the reinforcing bar ends and dimensional requirements of upset ends For field fabricated Type 2 splices: For connections under the IBC each steel reinforcing bar shall be tested in static tension and develop 100 percent of the specified tensile strength and 125 percent of the specified yield strength of the steel reinforcing bar For field fabricated bar ends tests shall be conducted prior to the start, periodically throughout the job, and submitted to the building official to demonstrate the requirements of and For field fabricated Type 1 splices: For connections under the IBC each steel reinforcing bar shall be tested in static tension and develop 125 percent of the specified yield strength of the reinforcing bar For field fabricated bar ends, tests shall be conducted prior to the start, periodically throughout the job, and submitted to the building official to demonstrate the requirements of CONDITIONS OF USE Special inspection shall be provided at the jobsite as required by IBC Section 1704, as applicable. In addition to verifying placement of reinforcing bar splices, the special inspector shall verify field preparation of components (including field preparation of reinforcing bar ends) and assembly of the components resulting in spliced reinforcing bars. 6.0 EVIDENCE SUBMITTED Data in accordance with ICC-ES Acceptance Criteria for Mechanical Connector Systems for Steel Reinforcing Bars (AC 133), Effective June Page 2 of 6

3 7.0 IDENTIFICATION All couplers shall be packaged with a label bearing the manufacturer s name (HRC), address, model (500/510), bar size, and the IAPMO ES Mark of Conformity. Each HRC component is permanently marked with the product designator (HRC ), bar size, heat number, and T2 for Type 2 splice type.

Quality Control When properly fabricated and installed, the HRC 500/510 series can be visually inspected after installation to ensure proper fabrication. See Figure 2 for illustration of visual inspection. If heads are too thick, threads are visible. If heads are too thin, the coupler will not tighten the bars before bottoming out. HRC Go/ No Go gauges may be used to verify proper fabrication. Standard head dimensions used with coupler system are listed in Table 2. FIGURE 2 500/510 VISUAL INSPECTIONS Page 4 of 6

L min! 6d b or min of 6 Step 2: Heat about 2 bar diameters around the head of the steel Step 5: If the Xtension bars are already prefabricated and cooled the connection can be assembled by hand, but a torque-wrench should be applied to ensure the connection is tight. Tighten the connection to the torque values listed in Table 1. L min! 2d b Step 3: Slide the Xtender machine all the way over the bar end and lock the grips by tightening the wheel. Page 6 of 6
