2.2.16 HAC-T EDGE LITE, HAC-T EDGE, AND HAC-T S EDGE
Hilti Anchor Channels with serrated channel lips and rebar
edge confinement plate (HAC-T EDGE Lite and HAC EDGE) and
HAC-T EDGE with superior steel performance (HAC-T S EDGE)
are offered in HAC-T50 profiles. The anchor channel is identical
to its matching HAC-T, except the rebar edge confinement plate
(EDGE Lite or EDGE plate) is incorporated for superior concrete
performance in shear.
The standard portfolio consists of HAC-T50 with two defined
nominal anchor heights; 4.31” (109.50 mm) and 3.84” (97.50
mm). Moreover, defined channel length, EDGE Plate geometry,
rebar lengths, anchor and rebar diameter, and number of rebar
are also defined. The number of anchors per channels is pre-
defined and can be modified and ordered upon request. Refer
to section 2.4 for additional information about standard items
and lead times.

The concrete edge shear confinement plate (EDGE plate) is
fixed to the form work or pour stop. The EDGE plate comes with
installation holes. As an added value, the product comes with
the specified edge distance (c a1 ).
*For all-lightweight concrete, c a1 = c a2 = 2.95” (75 mm)

These anchor channel systems consist of HAC-T and the new rebar edge confinement plate (EDGE plate). The EDGE plate is not
structurally attached to the anchor channel. This allows decoupling of the tension and shear forces. HAC-T50 EDGE C comes with
an offset rebar and increased height of the front plate.

The minimum corner distances for pair of HAC-T in top of slab
corners (c a2 ) are consistent with table 2.2.15.1. These minimum
distances are based on installation requirements. Both HAC-T at
Additional measurements shall be taken into consideration
to account for the negative influence of the adjacent anchor
channel, if both channels are to be loaded simultaneously. See
chapter 9, Special Anchor Channel Design for additional design
information.
This anchor channel is equal to its matching HAC-T EDGE, except the "S" bracket is added. The "S" bracket offers superior steel
performance. The S bracket is structurally attached to the anchor channel. The S-bracket has a similar geometry to the connected
channel profile to ensure direct bearing of the S bracket on the channel profile
AC232 does not include provisions to account for the influence
of an adjacent and/or corner channel. Technically, HAC-T can be
used in both sides of the corner.

Hilti has developed a model to account for the influence
of adjacent and corner channels. The model follows the
fundamentals of AC232 and allows analysis of more complex
but typical applications encountered in a project such as the
conditions shown in Figure 2.2.15.3. See chapter 9, Special
Anchor Channel Design for additional design information.

required based on the structural adequacy of the concrete at

However, two HAC can be installed next to each other in a
corner configuration where the anchor channels are installed
perpendicular to each other.

AC232 provides design guidelines to account for the influence of
corners where only one anchor channel is present. The design
of this type of application is covered in ESR-3520. Table 2.2.15.1
provides the minimum edge and corner distances for and HAC-
30. HAC-T and HAC-30 requirements for top and bottom of slab
corners are equal.
corners cannot be installed at the minimum corner distance due
to physical constraints (clashing of HAC-T will occur).
