Definitions
- These can be mechanically acting flaps or bulkheads, or also other types of closures, such as so-called fire protection plates, which have the property that they act on a multiple of their initial volume when exposed to high heat (eg from approx. 80 ° C) swelling.
- a large number of these plates, placed parallel to one another, are introduced into the cross section of the supply and exhaust air ducts by means of a frame, holder or suitable other constructions in such a way that the plate planes coincide with the flow direction or are parallel to it. In this way, the air in the channels between the plates can flow through unhindered in the initial state, ie when these fire protection plates are thin. In the event of fire or other heat, however, these fire protection plates swell so much that they touch each other and even fuse with each other, so that the flow cross-section is completely interrupted.
- the heat dissipation is sufficient to prevent the flames from breaking through at least for the time required by the fire protection plates to completely seal the closure . It is of course advisable to arrange the individual layers of the expanded metal transversely to the direction of flow through the ventilation ducts in order to ensure lateral heat dissipation, that is to say to the walls of the ventilation duct.
- a large number of such expanded metal layers is particularly advisable if there is a fear that fires occurring within such a short spatial distance will have such a large temperature gradient that the frontmost layer of expanded metal facing the source of the fire will already melt and become ineffective while the Layers facing away from the source of the fire are still fully functional with regard to their heat dissipation.
- packing elements could also be used, i.e. mostly spherical structures that consist of expanded metal and therefore only have a low mass and a large number of small cavities, with the possibly greater flow resistance compared to such a filling material packing a package of layered expanded metal of the same thickness must be taken into account.
- Packings should be preferred.
- one or more such inserts can be arranged in the flow direction of the duct in front of and / or behind the fire protection panels in the cross section of the ventilation duct, or such an insert is even made of fire panels between two existing closures used. Expanded material and fire protection panels can also be accommodated in a common frame.
- both the insert made of expanded metal and the package of fire protection plates or both together can be designed so that they completely fill the inner cross section of the uninterrupted channel or so that the channel for a corresponding Distance is completely interrupted, and in this gap the inserts or packages are inserted, which is therefore a larger cross-section than the one to be protected Have channel.
- the sealing of the duct cross-section from the environment is likely to be more difficult than when inserting the inserts and packages directly into the cross-section of the ventilation ducts.
- arranging the metal-filled insert in front of the fire protection panels has the advantage that the filter effect is reserved for the expanded metal-filled insert, with the result that primarily this metal-filled insert becomes dirty during normal operation, while the fire protection panels behind it remain relatively clean.
- This not only has the advantage that the fire protection panels are thermally insulated if necessary by a perhaps very thick layer of dirt, which results in the fire protection panels responding too late, but that these panels only have to be cleaned extremely rarely or not at all even in normal operation.
- Fig. 1 shows a longitudinal section through a ventilation duct, the wall of which is designated by 1 and whose, for example, rectangular cross section is to be indicated by the dashed lines. As indicated by the flow direction 6, air or another gas flows through this channel.
- both the insert 10 and the package 11 can be inserted into the ventilation duct through an opening in the wall 1 transversely to the flow direction, which is closed by a door 2 during normal operation of the ventilation duct.
- This door 2 is articulated on the wall 1 by means of a hinge 4 and is held tightly pressed against the wall 1 in the closed state by means of a locking mechanism (not shown), a circumferential seal 3 being arranged between the wall 1 and the edge of the door 2 to keep the interior of the ventilation duct sealed from the surroundings.
- a locking mechanism not shown
- a circumferential seal 3 being arranged between the wall 1 and the edge of the door 2 to keep the interior of the ventilation duct sealed from the surroundings.
- fire protection panels and expanded material can also get into the ventilation duct in another way.
- the package 11 consists in a known manner of a holder 13 into which the individual fire protection plates 12 can be inserted, so that a compact package 11 is formed, which is brought into the cross section of the ventilation duct.
- a holder 13 into which the individual fire protection plates 12 can be inserted, so that a compact package 11 is formed, which is brought into the cross section of the ventilation duct.
- insert 10 which contains individual layers 9 of expanded metal, lies in front of package 11 with fire protection plates 12.
- This insert 10 consists of pages 7, which form a closed profile corresponding to the inner contour of the ventilation duct.
- These sides 7 are supplemented by transverse reinforcements running transversely to the flow direction 6 of the ventilation duct, which hold the layers 9 of expanded metal in their position transversely to the flow direction 6 and are intended to prevent these layers from bending, which inevitably means that the edges of these layers 9 do not touch the sides 7 of the insert 10 and thus the wall 1 of the ventilation duct would result, which would greatly impair the heat dissipation to the outside.
- a layer of transverse reinforcements 8 is designed to be removable from the sides 7, so that after removing these transverse reinforcements 8 the layers 9 of expanded metal can be removed from the insert 10, cleaned or replaced without any problems.
