2. Air-termination rods with concrete block<br />
The air-termination rods listed below (see table 2) are supposed to protect roof superstructures<br />
and can be adjusted to roof inclinations up to max. 10 degrees.<br />
The air-termination rods are dimensioned for wind speeds up to 145 km/h and 161 km/h<br />
(wind load zone II + III in accordance with DIN 4131).<br />
2.1Installation<br />
When installing the concrete block, it has to be observed that the braces and the continuous<br />
concrete recess of the concrete blocks are aligned in a straight line. Thus, maximum stability<br />
of the brace frame and the air-termination rod is achieved when driving in the wedges (see<br />
Fig. 2, page 4).<br />
2.1.1 Concrete block<br />
For mechanical stabilisation of the air-termination rod and protection against possible wind<br />
load effects, a concrete block has to be installed on every bracing.<br />
Depending on the total length of the relevant air-termination rod, a concrete block with a<br />
weight of 8.5 kg or 17 kg is installed per brace (see table 2 and Fig. 2, page 4).<br />
Note:<br />
For additional protection of roof sheetings it is advisable to use ground plates, Part No. 102<br />
050 or 102 060, when installing the concrete blocks (see Fig. 2, page 4).<br />
The air-termination system may not be installed on sheet metal roofs!<br />
