Specifications of intended use
Anchorages subject to:
Static and quasi static loading.
Base material:
Reinforced or unreinforced normal weight concrete according to EN 206.
Strength classes C12/15 to C50/60 according to EN 206.
Maximum chloride content of 0,40 % (CL 0.40) related to the cement content according to EN 206-1.
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 to at least 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
-40 °C to +80 °C (max. long term temperature +50 °C and max. short term temperature +80 °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 EN 1992-1-1, Annex B2 and Annex B4.
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),
compressed air drilling (CA)
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 for the overlap joint).
Injection system Hilti HIT-HY 150 MAX
