Loading 1.2.1 HILTI ANCHOR CHANNEL PORTFOLIO AT A GLANCE Hilti’s simplified and value engineered cast-in anchor channel system portfolio, in conjunction with PROFIS Anchor Channel, helps designers to easily provide model code compliant and cost-effective anchor channel system solutions. HAC's standard portfolio covers most of the extreme project conditions. For a broader application coverage range, custom solutions are offered upon request. The Hilti Channel Bolts (HBC), commonly known as t-bolts are part of the HAC system. HBC have proprietary bolt head geometry compatible with HAC profiles. HBC are offered in different types, diameters, steel grades, finishing, and lengths. Although serrated t-bolts cannot be used with smooth lip channel profile or vise-versa, t-bolts for each profile type (smooth or serrated) can be used in all corresponding channel profile sizes. Numerical simulations allowed Hilti to design a range of channel profiles with different anchor configurations, resulting in a synergized steel to concrete performance. Hilti Anchor Channels with smooth lips (HAC) and serrated lips (HAC-T) are covered by ICC ESR-3520. The geometry of HAC versus its matching HAC-T profile (i.e. HAC-50 vs HAC-T50) is identical, with the main difference of the lip type. Generally, HAC and its equivalent HAC-T offer similar performance. The 11. Best Practices 12. Instructions for Use 13. Field Fixes 14. Design Example main advantage of HAC-T is that it offers higher slip resistance at a lower installation torque. HAC profiles (40, 50, 60, and 70) and HAC-T profiles (50 and 70) are the backbones of the Hilti’s anchor channel portfolio. Such profiles are utilized in all different anchor channel types. It is only the type of anchor and connection that changes or additional accessories are incorporated. For instance, HAC- 50 with rounded head anchors has the same channel profile as HAC-50 with reinforcing bar anchors (HAC-50 CRFoS U). The innovative manufacturing channel technology allows different channel profiles to have a relative constant channel width, permitting one t-bolt head size to be used in all different channel sizes, streamlining product portfolio and simplifying installation on the job site. This means more cost-effective t-bolts via economy of scale. HBC-C-N HAC-50 HAC-60 HBC-C HAC-70 T-bolts for HAC (smooth lips) and HAC-T (serrated lips) are not interchangeable. HAC HAC-T (smooth profile) (serrated profile) HAC-40, HAC-50, HAC-60, & HAC-70 HAC-T50 and HAC-T70 Seismic approved All Hilti channels come with end caps, filler foam, and a tear-out strip for a smooth and clean installation. The product comes with special identification marks to minimize the probability of confusion on the jobsite. The standard HAC portfolio consists of predetermined anchor channel configurations which allow for shorter lead time. The standard portfolio consists of fixed channel lengths, number of anchors per channel, anchor type (rounded headed anchors, reinforcing bar anchors, and/or EDGE plate), anchor diameter, and anchor length. Seismic approved Optimized design Lower installation torque for seismic applications Filler, tear-out band, and end caps Optimized design Filler, tear-out band, and end caps Note: Hilti Anchor Channels are a value engineered solution that in addition of preserving the high product performance, they have improved the function and features of the traditional anchor channel system, creating differentiated and innovative solutions that bring added value to the cast-in industry. 22 10. Design Software 1.2.2 HILTI ANCHOR CHANNEL PROFILES HAC-40 The Hilti Anchor Channel (HAC) portfolio consists of two different V-shape channel profile types; smooth and serrated lips. To feasibly cope with the typical and non-typical conditions encountered in a project, different channel profiles sizes (HAC-40, 50, 60, and 70), channel lengths, and a versatile configuration of anchors have been integrated into the standard HAC portfolio. 9. Special Anchor Channel Design Hilti Anchor Channel (HAC) design models are based on state-of-the-art compliance with International Council Code Evaluation Service Report 3520 (ICC ESR-3520). Design models of anchor channels not explicitly covered by ICC Acceptance Criteria 232 (AC232) are based on applicable provisions of U.S. Concrete Standard ACI 318 and AC232, and ESR-3520, as applicable. Moreover, all Hilti Anchor Channel have been tested following applicable AC232 testing protocols. 8. Reinforcing Bar Anchorage 1.2 HAC OVERVIEW 7. Anchor Channel Design Code HAC-30 has been added to the Hilti Anchor Channel portfolio. Although its channel profile does not have "-T", HAC-30 comes with serrated lips.
