II SPECIFIC CONDITIONS OF THE EUROPEAN TECHNICAL
APPROV
AL
1 Definition of product and intended use
1.1
Definition of product
The
Hilti
HIT-CT
1
is
used
for
the
connection,
by
anchoring
or
overlap
joint,
of
reinforcing
bars
(rebars)
in
existing
structures
made
of
ordinary
non-carbonated
concrete
C12/15
to
C50/60.
The
design
of the post-installed rebar connections
is done in accordance with
EN 1992-1-1 October 2005
(EN 1992-1-1).
Covered
are
rebar
anchoring
systems
consisting
of
Hilti
HIT-CT
1
bonding
material
and
the
Hilti
tension
anchor
HZA-R
sizes M12,
M16
and
M20
or
an
embedded
straight
deformed
reinforcing bar
diameter,
d,
from
8
to
25
mm
with
properties according to
Annex
C
of EN 1992-1-1
and
EN
10080.
The classes B and C of the rebar are recommended.
1.2
Intended use
The ETA covers applications in non-carbonated concrete
C 12/15 to
C 50/60 (EN 206-1) only, which
are
also
allowed
with
straight
deformed
cast-in
bars
according
to
EN
1992-1-1,
e.
g.
those
in
the
following applications:
overlapping joints with existing reinforcement in a building component, Figure 1 and 2 in annex 2.
anchoring of the reinforcement at an end support/bearing of a slab or a beam designed as simply
supported as well as its reinforcement for restraint forces, Figure 3 in annex 2.
anchoring of reinforcement of building components stressed primarily in compression, Figure 4 in
annex 2.
anchoring of reinforcement to cover the line of acting tensile force, Figure 5 in annex 2.
Rebar
connections with
the
Hilti
HZA-R may be
used
for
the
transmission
of
tensile
forces in
the
direction of
the bar axis
only.
The transmission
of shear forces has to
be ensured by appropriate
measures, Figure 6, 7 and 8 in annex 3.
The Hilti HIT-CT 1anchoring systems can be used with the following limitations:
9
The
rebars
can
be
placed
in
holes
made
with
hammer
drilling,
hollow
drilling
Hilti
TE-CD/TE-YD or compress air drilling only
9
The rebars may be used in the following temperature range :
-40°C to +80°C (max short term
temperature +80°C and max long term temperature +50°C)
9
According
to
EN
206-1
the
allowable
chloride
content
in
concrete
is
limited
to
0.40%
(Cl 0,40) related to cement content.
9
The rebars may be installed in dry or wet concrete, but must not be installed in flooded holes.
9
The rebar connections may be used for predominantly static loads.
The fire resistance of post-installed rebar connections is not covered by this ETA.
Fatigue, dynamic or seismic loading of post-installed rebar connections are not covered by this ETA.
The provisions made in this European Technical Approval are based on an assumed intended
working life of the rebar connections of 50 years.
The indications given on the working life cannot be
interpreted as a guarantee given by the producer, but are to be regarded only as a means for
choosing the right products in relation to the expected economically reasonable working life of the
works.
