<br />Structural
<br />2.0 USES
<br />The Hilti HIT-HY 270 Adhesive Anchor System is used to
<br />anchor building components to hollow (ungrouted) and fully
<br />grouted concrete masonry walls, and hollow (ungrouted)
<br />brick masonry walls. Threaded rods, steel reinforcing bars,
<br />and internally threaded inserts installed with Hilti HIT-HY
<br />270 can resist static, wind, and earthquake loads, as noted
<br />in Section 4.0 of this evaluation report. The anchor system
<br />is an alternative to Section 8.1.3 (2016 or 2013 editions) or
<br />Section 2.1.4 (2011, 2008 or 2005 editions) of TMS 402/ ACI
<br />530/ ASCE 5, as applicable, as referenced in Section 2107
<br />of the IBC. The anchor system may also be used where an
<br />engineered design is submitted in accordance with Section
<br />R301.1.3 of the IRC.
<br />3.0 DESCRIPTION
<br />3.1 General:
<br />The Hilti HIT-HY 270 Adhesive Anchor System is comprised
<br />of the following components:
<br />• Hilti HIT-HY 270 adhesive
<br />• All -threaded steel rods, steel reinforcing bars, or Hilti HIS
<br />steel internally threaded inserts (grout -filled concrete
<br />masonry)
<br />• All -threaded rods, bolts, cap screws, studs, Hilti HIT -IC
<br />internally threaded inserts, and Hilti HIT -SC
<br />plastic -mesh screen tubes (hollow concrete masonry and
<br />hollow brick masonry)
<br />3.2 Materials:
<br />3.2.1 Hilti HIT-HY 270 Adhesive: The Hilti HIT-HY 270 is
<br />an injectable hybrid adhesive mortar consisting of urethane
<br />methacrylate resin, hardener, cement and water. The resin
<br />and cement are separated from the hardener and water by
<br />means of a dual -cylinder foil pack attached to a manifold.
<br />An injection nozzle with an internal mixing element is
<br />attached to the manifold, and the adhesive components are
<br />dispensed through the injection nozzle to ensure their
<br />proper mixing. The injection nozzle may be replaced to
<br />permit interruptions in the use of the cartridges. Available
<br />cartridge sizes include total mixed volumes of 11.1 ounces
<br />(330 mL) and 16.9 ounces (500 mL).
<br />The adhesive expiration date is printed on the manifold of
<br />each foil pack (month/year). The shelf life, as indicated by
<br />the expiration date, is for an unopened foil pack stored in a
<br />cool, dry, dark environment at temperatures between 41 °F
<br />and 77°F (5°C and 25°C). Gel and curing times for the Hilti
<br />HIT-HY 270 adhesive, and the respective masonry
<br />temperature during installation and cure, are shown in
<br />Tables 1A and 1B.
<br />3.2.2 Hole Cleaning Equipment:
<br />3.2.2.1 Standard Equipment: Standard hole cleaning
<br />equipment, comprised of steel wire brushes and air nozzles
<br />is described in Figure 5 of this report.
<br />3.2.2.2 Hilti Safe -Set TM System: When the Hilti TE-CD or
<br />TE-YD hollow carbide drill with a carbide drilling head
<br />conforming to ANSI B212.15 is used in conjunction with a
<br />Hilti vacuum with a minimum value for the maximum
<br />volumetric flow rate of 129 CFM (61 t/s), the Hilti TE-CD or
<br />TE-YD drill bit will remove drilling dust, automatically
<br />cleaning the hole.
<br />3.2.3 Threaded Steel Rods (For Use in Fully Grouted
<br />Concrete Masonry and with Plastic Mesh Screen Tubes
<br />in Hollow Masonry): Threaded rods, having diameters
<br />described in Tables 3A through 10 of this report, must be
<br />clean, continuously threaded rods (all -thread). Carbon steel
<br />threaded rods must be in accordance with ASTM A36,
<br />ASTM A307, ASTM A193 Grade B7, ISO 898 Class 5.8.
<br />Stainless steel threaded rods must conform to ASTM F593
