2.3 Installation
The spacer with EB element is installed into a 17 kg concrete base.
Move the spacer closer to the concrete base from above and insert it into the hole of the concrete
base. To mechanically fix the spacer, insert a wedge into the hole of the concrete base. Mount the
MV clamp in the lower part of the spacer. Observe the releva
nt tightening torques (see Fig. 2.3).
2.4 Adjusting the height of the spacer with EB element according to the separation
distance „
s
air
“
The height of the spacer can be adjusted according to the calculated separation distance
„
s
air
“
.
The length L of the spacer must be at least equal to the separation distance
„
s
air
“
. L is the length
between the lower edge of the EB element and the top edge of the concrete base (see Fig. 2.3).
Note:
To protect roof sheetings or sensitive roof surfaces, it is advisable to position concrete bases on
support plates (Part No. 102 050) (see Fig. 2.3).
