2. Air-termination rods with concrete block
The isolated air-termination rods listed below (see Table 1) are supposed to protect roof su per struc tu res
and can be adjusted to roof inclinations up to max. 10 degrees.
2.1 Installation
When installing the concrete block, it has to be observed that the braces and the con ti nuous concrete
recess of the concrete blocks are aligned in a straight line. Thus, maximum stability of the brace frame
and the air-termination rod is achieved when driving in the wedges (see Figure 3 on page 5).
2.1.1 Concrete block
For mechanical stabilisation of the tubular air-termination rod / air-termination rod and protection
against possible wind load effects, a concrete block has to be installed on every bracing. Depending on
the total length of the relevant tubular air-termination rod / air-termination rod, a concrete block with
a weight of 8.5 kg or 17 kg is installed per brace (see Table 1 and Figure 3 on page 5).
Note:
For additional protection of roof sheetings, it is advisable to use support plates, Part No. 102 050 or 102
060, when installing the concrete blocks (see Figure 3 on page 5).
The air-termination system must not be installed on metal roofs!
