CONCRETE:
•
Can be used for all types of soil and rock
•
Dig a hole for the concrete foundation 111
•
Drill the rear anchoring 07 ; the project engineer calculates the
lengths of the anchors
•
Prepare the concrete foundation 111 ; the concrete foundation 111 is
dimensioned and reinforced in accordance with the information from
the project engineer
•
Mortar in the rear anchoring 07 with the fastening nuts 10 and spac-
ers 09
•
Install both anchors 08 with the help of the base plate 29 . Spacers
09 and fastening nuts 10 must be fixed on both sides of the
base plate ;
length of anchor 08 L = 500 mm
•
Fill in the concrete foundation 111
•
Tighten the fastening nuts 10 to approx.
30 kN pretensioning force
ROCK:
•
Remove rock around the base plate 29 at 0
– 30° to the horizontal
•
Drill holes for the anchor 08 that are vertical to the base plate 29 in-
to the rock 112
•
Mortar in the anchor 08 ; the project engineer calculates the lengths
of the anchors
•
Position the base plate 29 in the levelling layer of mortar
•
Tighten the fastening nuts 10 with the spacers 09 to approx. 30 kN
pretensioning force after the mortar has fully hardened
Tightening torque of the fastening nut for an anchor pretensioning force of approx. 30 kN:
Swiss-GEWI NG 20 Swiss-GEWI NG 25 Swiss-GEWI NG 28 Swiss-GEWI NG 32
Tightening torque 200 Nm 300 Nm 400 Nm 400 Nm
You must use mortar that is resistant to both frost and de-icing salt.
Reinforcement: 12 mm rebar diameter, 150 mm apart
An installation template can be supplied on request.
Please ensure the anchors have sufficient contact with the mortar, create a good bond, and that enough of the sur-
face makes contact with the surrounding material.
You can find more information about anchoring the base plate in the anchor data sheet.
The forces that may occur in the event of a rockfall event must not be underestimated. Civil engineering and installa-
tion work must therefore be carried out by experts.
