Technical Approval
ETA - 11/0390
Injection System Hilti HIT-CT 1 for rebar connection
Figure 9
:
Reinforcing bar “rebar” according to EC2
Refer to EOTA TR 023:
This Technical Report covers post-installed rebar connections in non-carbonated concrete under
the
assumption
only
that
the
design
of
post-installed
rebar
connections
is
done
in
accordance
with EN 1992-1-1.
Covered are rebar
anchoring systems
consisting
of bonding material
and
an embedded
straight
deformed reinforcing bar with
properties according to Annex C of
EN 1992-1-1; classes B and
C
of the rebar are recommended.
Refer to EN 1992-1-1 Annex C Table C.1 and C.
