HALFEN Cast-in channels HTA-CE
Dimensioning acc. to CEN/TS 1992-4:
2009 applying to European Technical
Approval ETA-09/0339
HALFEN Channels are supplied with a Combi strip filler and
with punched holes for nailing to the formwork. Possibly
overlapping Combi strip filler has to be cut flush at the
channel end. When fixing to the formwork, make sure that
the type of HALFEN Channel (profile, material, length) and
its position is in accordance with the drawing. Fix channels
securely so that they will not be displaced during the pou-
ring of the concrete and remain flush with the surface of
the formwork. If no formwork is available to nail, choose
other fixing method.

1. Type identification/ General information
!
To avoid any rust contamination on stainless
steel HALFEN Channels:
Remove steel packing ribbons immediately.
Store separately with sufficient distance to other
metals. Avoid damage of surface and contami-
nation due to contact with carbon steel.
Dry, roofed and well ventilated storage is recom-
mended.

A range of different short lengths is supplied.
HALFEN Channels can also be cut to length on
site. At both ends of the cut piece a projection of
25 - 35 mm must remain between the first/last an-
chor and the end of the channel piece. HALFEN
Channels must have at least 2 anchors.
HALFEN Cast-in channels with site applied
end anchors
ANK-E End anchors are officially approved under
approval no. Z-21.4-34 DIBt Germany. They are
not part of the European Technical Approval
ETA-09/0339.
ANK-E are not included in the delivery of HALFEN
Channels. Please order separately in same material
and finish as HALFEN channel.
Cut the HALFEN Channel as required. The cut
section must be perpendicular to the channel axis.
Maximum and minimum projections ”e” at the
ends of HALFEN Channel are 175/225 and 35
mm.
Select the type of ANK-E End anchor to fit to the
HALFEN Channel according table below. Push the
clamping element on the channel back until it
comes to full stop; press in the foam filler when
necessary.
Pull tight the hex head bolt to the torque indicated
in the table below.

4. Installation variants
4.1.1 Fixing by using the HALFEN T-head bolt through
formwork penetration.
4.1.2 Using aluminium rivets (by contractor) through the
nailing holes of the HALFEN Cast-in channel.
4.2.1 Fixing with nails:
Fixing to timber formwork with nails through the
punched holes in the back of the channel. When
fixing stainless steel channels, HALFEN recom-
mends the use of stainless steel nails.
HALFEN provides stainless steel nails in size
2.8/65 with order code „ENA“.
Steel formwork
Timber formwork
4.2.2 Fixing HALFEN channels 28/15 up to 52/34
with staples:
Nail HALFEN channel to timber formwork with a
sufficient number of staples.
Order code: „KRA“.
4.3.1 Fixing with auxiliary construction see adjacent pic-
ture. Concrete compaction has to be performed
very carefully with a vibrating cylinder (distance to
the HALFEN Channel closer than 5-times of the cy-
linder diameter), in order to prevent air bubbles
underneath the channel.
4.4.1 Fixing from above directly to the reinforcement:
attach the HALFEN channel by wire binding.

Accurate concrete compaction in the area of the HALFEN Channel is required!
Installation by placing the channel after casting in the wet concrete is not recommended!
If this kind of installation cannot be avoided, very careful concrete compaction after placement of the channel is
essential (minimum 10 seconds for short channels or 20 seconds per meter for long channels on either side with
a vibrating cylinder or 10 seconds total with a vibrating table).
For appropriate application of HALFEN
T-head bolts see bolt instructions

Application of T-head bolts
4.4.2 Fixing from above to the reinforcement, using
HALFEN ChanClip
Attach the HALFEN ChanClip to the HALFEN
Channel, the ribbed pin of the ChanClip must
be pushed into one of the nail holes in the
HALFEN Channel. At least 2 ChanClips per
channel are required.
Snap in auxiliary bars diam. 8 or 10 mm
(rebars B500 B, by contractor) at the required
position into the ChanClip. Apply the HALFEN
Channel mounted with the ChanClip and the
auxiliary bars to the reinforcement.
Check the appropriate height and attach the
bars by wire binding.
HALFEN ChanClip
Catch the combi strip filler at one end and pull it out by
hand with the simultaneously aid of a tool, e.g. screwdri-
ver.
