I have 3 projects where I have to install B7 Anchor rods that are anchoring and telecommunications monopoles
First one 12 pcs 1.375 x 72" B7 Anchor rods, embedded 1145mm deep x 38mm diameter hole.
Second 18 pcs 1.375 x 66" B7 Anchor rods, embedded in a 1145mm deep x 45mm diameter hole.
Third10 pcs 2" x 88" B7 Anchor rods , embedded in a 1525mm deep x 54mm diameter hole.
These massive rods are anchors for 100m tall telecommunication towers.
My questions are, what epoxy is adequate for these applications? What are there limitations? And the amount of cartridges required?
The website and app volume calculator doesn't allow for these sizes. Furthermore the technical data sheet also maxes out at 1.25dia B7 rods with no information beyond. Posing the question of limitations.
Hi Greg,
Thank you for reaching out.
For anchoring into deep embedment, we recommend exploring the HILTI HIT-RE 500 V3 EPOXY as it has guidance for deep embedment based on rebar development theory.
To first explore our guidance and technical data, please see the Post-installed reinforcing bar guide and Technical bulletin for HIT-RE 500 V3 for deep embedment.
Additionally, our ICC-ES ESR 3814 and ICC-ES ELC 3814 for anchoring into concrete are excellent resources to review.
Similarly, when anchoring with large diameter elements, we also recommend exploring the HILTI HIT-RE 500 V3 EPOXY as it has additional testing for diameters up to 2-1/2”. Please see our Technical Bulletin for our published data.
Finally, if you have any further questions, please reach out to ca.engineeringtechnicalservices@hilti.com so we can better assist you.
Thank you.
