1 All values are for anchor installed in hollow core concrete with minimum compressive strength of 7,000 psi. Due to variations in materials and dimensional congurations, on-site testing is required to
determine the actual performance of the anchor. Allowable loads are calculated using a safety factor of 5.
2 Tabulated embedment depth is limited by the plastic HIT-SC 16x50 mm screens. See gure 5.
3 The required concrete thickness is the thickness for which values are available and installation is recommended. Anchors shall be installed along the centerline of the hollow core or along the line of
minimum thickness. Verify these requirements with the hollow core plank supplier before installation. The required thickness is measured from the inner to the outer side of hollow core panel. See
gure 5.
4 Tabulated allowable loads must be the lesser of the adjusted bond values tabulated and the steel values in table 3 of Section 3.2.5 of Hilti Product Technical Guide Volume 2, Ed. 19.
5 Allowable loads shall be adjusted for increased base material temperature in accordance with Figure 6.
6 The adhesive gel and cure times shall be identical to the values adopted for masonry.
7 For combined loading: (T
