ROCK:
•
Level the rock 0° - 30° from horizontal underneath the base
plate 29
•
Drill into rock 112 the two holes perpendicular to the base
plate 29
•
Grout in the anchors 08 , the calculation of the anchor length
is set by the project engineer
•
A thin levelling layer ensure a stable placement of the base
plate
•
Position base plate 29 into levelling layer
•
Fasten the nuts 10 until an initial tensile force of approx. 30
kN is reached
Tightening torque for nuts to reach an initial tensile force of approx. 30 kN:
Swiss GEWI NG 28 Swiss GEWI NG 32
Tightening torque 400 Nm 400 Nm
Frost and icing-salt resistant mortar has to be used
Reinforcement: 12 mm-rod diameter in distance of 150 mm
If requested an installation template can be supplied.
It is important to ensure that the anchors have sufficient contact with the mortar and make good bond,
and a sufficient area to the surrounding material.
Further information about the anchoring of the base plate can be found on the anchor forces date sheet.
The forces that occur during a rockfall event are not to be underestimated. The civil engineering and in-
stallation work must therefore be carried out by professionals.
