Installation
The fitness for use of the rebar connection can only be assumed if the rebar is installed as follows:
The installation of the post installed rebars respectively HZA-R shall be carried out according to the
manufacturer’s installation instructions and this European technical approval, annexes 1 to 19;
The installation
of
post-installed
rebars respectively
HZA-R
shall
be
done only by suitable
trained
installer and under supervision on site. The conditions under which an installer may be considered
as suitable trained and the conditions for supervision on site are up to the Member States in which
the installation is done.
Use of the system only as supplied by the manufacturer without exchanging the components of an
system;
Checks before placing the rebar to ensure that the strength class of the concrete in which the rebar
is to be placed is in the range;
The surface of the joint between
new and
existing concrete should be prepared (roughing, keying,
according to the envisaged intended use according to EN 1992-1-1;
Check of concrete being well compacted, e.
g.
without significant voids;
Keeping the anchorage depth as specified in the design drawings;
Keeping of the concrete cover and spacing as specified in the design drawings;
The drilling and cleaning of the hole and the installation shall be performed only with the equipment
as specified by the manufacturer given in annexes 9 to 17. It shall be ensured that this equipment
is available on site and is used;
Positioning of the drill holes without damaging the reinforcement;
In case of aborted drill hole: the drill hole shall be filled with mortar;
The post installed rebar connection must not be installed in flooded holes;
Rebar installation ensuring the specified embedment depth,
that
is the appropriate
depth marking
of the rebar not exceeding the concrete surface;
4.5
Responsibility of the manufacturer
It
is
the
manufacturer’s
responsibility
to
ensure
that
the
information
on
the
specific
conditions
according to 1 and 2 including Annexes referred to in § 4.3. is given to those who are concerned. This

installation
data
shall
be
shown
clearly
on
the
package
and/or
on
an
enclosed
instruction sheet, preferably using illustration(s).
The minimum data required are:
drill bit diameter,
rebar diameter,
admissible service temperature range
hole depth,
minimum effective anchorage depth,
information
on
the
installation
procedure,
including
cleaning
of
the
hole
with
the
cleaning
equipments, preferably by means of an illustration,
material and property class of metal parts acc.
to Annex 4 and Tables 1 and 2 of Annex 6,
anchor component installation temperature,
ambient temperature of the concrete during installation of the anchor,
admissible processing time (open time) of the mortar,
curing
time
until
the
anchor
may
be
loaded
as a
function
of
the
ambient
temperature
in
the
concrete during installation,
maximum torque moment, where applicable (HZA-R),
reference to any installation tool needed,
identification of the manufacturing batch,
All data shall be presented in a clear and explicit form.
