PECIFICATION OF INTENDED USE
Anchorages subject to:
-
Static and quasi-static loading: rebar size
ϕ 8 to ϕ 32 mm.
Base material
-
Compacted reinforced or unreinforced normal weight concrete without fibres according to EN 206:2013+A1:2016.
-
Strength classes C20/25 to C50/60 according to EN 206:2013+A1:2016.
-
Maximum chloride content of 0,40 % (CL 0.40) related to the cement content according to EN 206:2013+A1:2016.
-
Non-carbonated concrete
.
Note: In case of a carbonated surface of the existing concrete structure the carbonated layer shall be removed in the area of the
post-installed rebar connection with a diameter of
ϕ + 60 mm prior to the installation of the new rebar. The depth of concrete to
be removed shall correspond at least to the minimum concrete cover in accordance with EN 1992-1-1. The foregoing may be
neglected if building components are new and not carbonated and if building components are in dry conditions.
Temperature in the base material
-
At installation:
-10 °C to +40 °C
-
In service
Temperature range I: -40 °C to +40 °C
(max. long term tempe24 °C and max. short term tempe40 °C)
Temperature range II: -40 °C to +80 °C
(max. long term tempe50 °C and max. short term tempe80 °C)
Temperature range III: -40 °C to +120 °C
(max. long term tempe72 °C and max. short term tempe120 °C)
Design
-
Anchorages are designed under the responsibility of an engineer experienced in anchorages and concrete work.
-
Verifiable calculation notes and drawings are prepared taking account of the forces to be transmitted.
-
Design under static or quasi-static loading in accordance with EOTA TR 069.
-
The actual position of the reinforcement in the existing structure shall be determined on the basis of the
construction documentation and taken into account when designing.
Installation
-
Use category: dry or wet concrete (not in flooded holes).
-
Drilling technique: hammer drilling (HD), hammer drilling with Hilti hollow drill bit TE-CD, TE-YD (HDB), or
diamond coring with roughening with Hilti roughening tool TE-YRT (RT).
-
Overhead installation is admissible.
-
Rebar installation carried out by appropriately qualified personnel and under the supervision of the person
responsible for technical matters of the site.
Check the position of the existing rebars (if the position of existing rebars is not known, it shall be determined
using a rebar detector suitable for this purpose as well as on the basis of the construction documentation and
then marked on the building component).
