Plugs are required for a fire resistance period of 90
minutes.
The following can be used for the various materials:
•
Concrete:
Fischer bolt anchor FAZ - II 8
•
Aerated concrete:
Fischer anchor M8 FPX - I
•
Concrete, aerated concrete, masonry:
Fischer injection mortar systems FIS V, VW, VS
together with the anchor rods FIS A – M8
Shims should be used if required.
Example
:

connected smoke extraction ducts.
Weights of EK90 smoke control dampers
⇒
see page 17
Example
EK90 smoke control dampers
between vertical smoke extraction
ducts are generally supported by
the lower sections of the smoke
extraction duct.
Fastenings for the smoke control
dampers must therefore match
the fastenings for the smoke
extraction ducts.
The specifications of the smoke
extraction duct manufacturer must
be observed.
•
Beams must fit tightly against the walls of the smoke
extraction ducts or on the casing of the smoke
control dampers. Otherwise, they will need to be
clad. This also applies to beams that are larger than
1.5 m in length.
•
Traverses should be at least U50 according to
DIN 1026.
•
Shims should be used as required.
Dowels must be suitable
and approved for fire
protection, and installed
accordingly.
Example
EK90 smoke control dampers in versions NL or NR
directly underneath ceilings.

The specifications of the smoke extraction duct manu-
facturer must be observed.
