Rapid fire protection duct

Product description
When mounted on a support system, ducts are screwed to support
profiles and fittings using the appropriate lock plates. In turn, these are
fastened to the ceiling using threaded rods. See also “6 Mounting on a
support system” on page 38.

Fastening base
The fastening substrate of PYROLINE
®
Rapid must possess a sufficient
load capacity and fulfil the fire resistance class required by the construc-
tion. The fastening material used must have been tested for fire protec-
tion and be suitable for the substrate (see “4.1 Fastening material” on
page 17).
For this reason, dry/lightweight construction walls are only partially suita-
ble for fastening the fire protection duct system. If they fulfil the required
fire resistance class, threaded rods can be used for fastening, e.g. with
push-through mounting. However, they can always be crossed using the
wall connection fitting (see “6.3.8 Mounting a wall/ceiling penetration” on
page 62).
Ceiling mounting may only take place on solid ceilings, or on such ceil-
ings (e.g. wooden beams or false ceilings) which have been classified by
a surveyor into a fire resistance class and for which a sufficient carrying
capacity has been guaranteed, e.g. through anchor extraction experi-
ments. Suspended ceilings are unsuitable for fastening.

Cable assignment/maximum load
The maximum approved total load is 30 kg per running duct metre. It may
not be exceeded, as otherwise the support and function capability is no
longer guaranteed.
