Anchor bolt
Prior to tensioning the anchor bolts, the finegrout concrete must have set for at
least 28 days.
•
Keep anchor bolts in their position by tightening the nut with your fingers.
•
Place the protective sleeve.
•
Place hydraulic tensioning device in position.
•
Initially tension the bolts alternately (for initialtensioning forces, see item 6.17).
•
Using a suitable tool, screw hexagon nuts on as far as the stop.
To ensure correct handling and setting of the initialtensioning tool the manufacturer’s
operating instructions must be adhered to.
The tensioning pressures and/or the initialtensioning forces should be recorded, see also item 7.2.10.
