Description

Device for supplying extinguishing agent

The invention relates to a device for supplying extinguishing agent, e.g. Water, to a building part, with at least one transverse line, which has along its course outlet openings for the extinguishing agent.

From DE 32 02 467 AI an arrangement for fire protection of exterior walls is known in which on the outer wall in the upper region is a generally horizontal, ie transverse, extending channel, a transverse line, is arranged for water. The channel is connected to a supply line for water and has directed to the outer wall openings for discharging the water. The openings are arranged in a row in the longitudinal direction of the channel. The channel can also be an open-topped channel to record what ^¬ water, which flows down the outer wall, and can forward to other parts of the outer wall. At the bottom of the outer wall, the water is collected and pumped back into the pipes with a pump.

In DE 199 09 494 AI further a fire extinguishing system is geof ^¬ disclosed, in which a nozzle is attached to an extendable by extinguishing agent pressure tube. At rest, the tube is arranged with the fire extinguisher behind a façade wall, which has an opening with an openable cover. If the fire-fighting system is triggered, pushing the driving out fire ^¬ extinguishing nozzle against the cover, which opens this way, so that the fire hose nozzle reaches its deletion position. The fire extinguishing nozzle ^¬, a sprinkler or a facade element, such as a trim, be.

FR 2 270 402 AI discloses a fire fighting system for tall buildings with a water tank provided on the roof of the building and delivery pipes for water and the like. to the outside of the windows and the facade of the building.

In DE 20 2014 105 974 Ul a portable on wheels wagons is shown as a mobile Löhneheit with a Löschmittelzusatzbehäl- ter to extinguishing water, which is mixed with an extinguishing agent additive in the form of an F-500 Encapsulator Agent, on a Burnout issue.

In the above-described prior art fire extinguishing water is released in a fire more or less uncontrolled, which is clearly in areas with scarce water resources is disadvantageous, since in case of fire more water than actually not ^¬ handy can be delivered.

It is therefore an object of the invention to propose a device as stated at the beginning, with which firefighting water can be controlled in a fire and thus economical, nevertheless efficiently discharged.

The inventive device of the type mentioned is characterized by a pressure limiter or -regier and or or a flow regulator to achieve a controlled extinguishing agent delivery at a site. Preferably, a single pressure limiter or regulator and / or a single flow rate regulator is provided for a plurality of outlet openings. Particularly preferred is a single pressure limiter or -regier and or or a single flow rate controller for each transverse line or for a plurality of transverse lines provided. The transverse line is intended for mounting on an outer wall, in particular a facade of a building. In this case, the transverse line can extend horizontally or obliquely on the outer wall or facade. On the outer wall or facade a plurality of transverse lines, in particular one above the other and / or next to each other can be provided. The outlet opening may be a bore, in particular a cylindrical bore in the transverse line.

With such a pressure or volume control, which can be mechanically adjusted, it is possible to ensure that a controlled amount of extinguishing agent (amount of extinguishing water) can be delivered at the ent ^¬ speaking points with a suitable pressure. Of particular importance is the fact that an optimal amount of water can be discharged, so that in water-poor areas water can be applied only in the absolutely necessary amount. It should be remembered that in

low-water areas, water as extinguishing water is usually available in water tanks with limited capacity, in which case this water should then be used optimally. in the With regard to installations away from densely populated residential areas, in zones where electricity is not necessarily available, a current-independent pressure control is of particular importance, this regulation being operated exclusively by water.

Furthermore, it is also important to check the pressure in the system and to avoid excessive pressure as a pressure in the system may affect the functionality and thus the optimal Beimi ^¬ research a fire-retardant substance (in this case should also be noted that current for a Regulation or control of the admixture often will not be available, and in particular in case of fire, a power failure is to be overcome.

In view of the fact that electric current may not be available, it is also advantageously provided to adjust the regulator (s) simply mechanically or manually, i. to refrain from electronic control. Of course, in situations where electrical power is reliably available, it would be possible to have an automatic, i. to install electronic control.

An advantageous embodiment is further characterized by a pressure gauge in the extinguishing agent supply, for their visual function test.

In order to achieve an improved functionality of the device, a preferred embodiment can be provided, which is characterized by a supply unit for an additive, for example a fire-extinguishing agent and / or a descaling agent, in water provided as extinguishing agent. It is also of particular ^¬ alia advantageous if the or the controller, as seen in the main flow direction of the extinguishing agent, is disposed in front of the additional feed unit or are.

In order to avoid any blockage in the line system, in particular bores or small openings (also in the transverse line), and to ensure longevity and freedom from maintenance of the ^device , it is favorable if a filter is arranged in the extinguishing agent supply is. Such a filter integrated in the system prevents clogging of holes by particles in the water. An increased calcification Depending on the quality of the water, it is prevented by adding a lime-dissolving substance. It should always be noted that the holes in the transverse line may have a diameter in the range of 1 to 2 mm, for example 1.5 mm, with such diameters a priori clogging will occur less frequently. This also favors the fact that the present device can be largely maintenance-free; gege ^¬ appropriate, is carried out by a simple operation of the water system without the addition of fire-retardant substances, a "purge" and can be done in this case, a simple "visual inspection".

The outlet openings or holes can also be protected against contamination when the transverse line is attached to a strip-shaped cover. In this case, the strip-shaped cover can be sealed on one longitudinal side, namely opposite the extinguishing agent outlet side, that is to say generally on the upper side, so that contamination from this side is prevented or at least made more difficult.

To protect the transverse line, also in mechanical terms, it is also advantageous if the transverse line is disposed within a channel formed on the back of the cover. The channel may be closed to the back of the cover through a channel back wall. In particular, the channel extends in the longitudinal direction of the strip-shaped cover. Here, it is favorable for easier access to the transverse line, if the channel is closed by a separate end ^strip on the front ^¬ side of the cover. The access to the channel is particularly easy here, if the end strip is geson ^¬ dert solvable, for example, is attached by means of a plug connection.

Due to the special design of the transverse duct with the bores facing downwards, which are defined by e.g. Protected nose-shaped covers can be achieved in an efficient manner protection against external environmental influences, such as wind, hail, but also sandstorm, etc., in contrast to conventional spray nozzles. It is further possible in the present device, that such usual per se

Components, such as pipes, solenoid valves, thermal sensors and water system components, inside least under overhanging ceilings, etc .; In this way they can be easily checked at any time inside the building and without any effort and if necessary maintained or replaced. There is then no work after installation - on the outside of the building - required, which makes a significant contribution to the safety of persons, in particular the service personal ^¬ nals, is made.

In modern facade constructions, so-called elemental facades, fire extinguisher strips can already be installed or integrated in the factory during production, so that on site only a connection to a routed water supply, without complex additional work from inside, is required. The water can be taken from an existing water supply system, but also from artificial water reservoirs such as basins or cisterns.

Finally, as far as the function is concerned, as a result of the arrangement and design of the bores or outlet openings at suitable small distances along the transverse line, a sufficient, full-surface wetting of a respective

(Building) wall can be achieved with liquid (water) and fire-retardant substance ^¬ , wherein by the fire-retardant substance, moreover, a low surface tension of the liquid can be ensured. The leakage of the liquid under pressure through the holes ensures direct adhesion of the liquid to the surface of the façade, unlike in the case of

Spray nozzles, which must be fixed at a predetermined distance from the façade outer surface and are exposed directly to environmental influences and weather-related circumstances, such as a wind drift through the wind, in the case of skyscrapers also by the thermal etc ..

The invention will be further explained with reference to preferred embodiments illustrated in the drawing, to which, however, it should not be restricted. In detail show:

Fig. 2 in relation to Figure 1 on an enlarged scale in detail the supply of extinguishing water in an area of a facade, behind a cover. and Fig. 3 shows schematically a perspective view of a facade with irrigation provided for cross pipes with lower, not closer apparent outlet openings from which schematically indicated water jets escape to the facade.

Fig. 1 shows, as mentioned, a scheme of a device for supplying extinguishing liquid, namely water, to sites on unspecified walls of a building or the like .. The device is connected to a water supply system, as indicated by an arrow A in Fig. 1 is. The connection is made via a manually operable shut-off valve 1, wherein a hand lever 1A is illustrated in an open position. Via a connector 2, a filter 3 connects to the shut-off valve 1, wherein this filter 3 may be of conventional design and is not explained here. By way of a reducing piece 4 and a distributor or a T-piece 5, on the one hand, an outlet stub 5A and, on the other hand, a manometer 6 with, for example, a pressure regulating valve 7 are connected. 8 in flow direction ^¬ seen immediately after the pressure gauge 6 follows an extinguishing agent supply means for supplying a per se conventional, suitable for the desired purpose extinguishing agent to the extinguishing water. With 9 is then another

Shut-off valve referred to the via a reducing nipple 10, a connecting piece 11 and to this then a T-piece 12, so another distributor, are connected. This T-piece 12 allows on the one hand the connection of a separate outlet 13 and the other part of a pipe fitting 14 to a T-manifold 15, the pipe connector 14, on the one hand, as indicated by an arrow 15A, leading to not further illustrated further solenoid valves, and on the other hand a reducer 16 allows the connection of a pipe 17 to a smaller cross-section port 18 of a solenoid valve 19, which is connected via an adapter 20 and a connection port 21 and a straight pipe section 22 to another T-piece 23 as a distributor, to different Water dispensing units 24, an example of which is shown in Fig. 2. To the corresponding T-connector 23 also includes another straight pipe section 25, to which a pipe elbow 26 and over this another branch with pipes to extinguishing water-discharge units 24 - as shown in FIG. 2 - leads. The Extinguishing water discharge units 24 have the transverse lines 36.

In Fig. 2, such an extinguishing water dispensing unit 24 is shown in Ver ^¬ bond with a wall 30, wherein the dispensing unit 24 with a support structure 31 to the wall 30, with a curtain wall 32, for example made of aluminum composite material, verbun ^¬ is , By way of example only, an attachment of this facade 32 to the supporting structure 31 via a sheet metal bracket 33, for example made of aluminum, is shown.

The water discharge unit 24 is shown in Fig. 2 in a cross section, and in itself strip-shaped, wherein it ih ^¬ rer the water ^discharge side (bottom) opposite upper ^¬ side has a seal 34 for sealing against the facade 32.

The water dispensing unit 24 is ^¬ closed, to a pipe 35 which extends through the wall 30, and water discharge unit 24 performs the interior of the (strip-shaped) via a toggle 35 to a transverse line 36 with at least one discharge nozzle or hole, wherein, moreover, in Fig. 2, a water jet 37 discharged from this transverse line 36 through the dispensing nozzle or bore can also be seen. The transverse line 36 is received within a behind the cover 24 A, ie in the water discharge unit 24, formed channel 38 which is closed at the left in Fig. 2 facing the outside with the help of a ^¬ closing bar 39, which in case of need, for about Service work, etc., can be removed to gain access to the interior of the channel 38.

From Fig. 3, the operation of such a device with generally transversely, but also as shown obliquely arranged transverse lines 36 results on a facade 32, with some of these transverse lines 36 exiting water jets 37 are illustrated schematically.

Of course, in the case of use, if a fire breaks out on a facade 32, only the transverse ducts 36 situated above this fire are to be activated with regard to the discharge of water in order to achieve efficient extinguishment of the fire.

The pressure control valve 7 allows a controlled release of extinguishing water in case of fire. It is in the interest of a particular ^¬ DERS simple design also possible, instead of the pressure control 7 easy to install a pressure limiter to limit the pressure of the water (or more generally the extinguishing liquid) upwards. It is advantageous in many cases may be, instead of limiting the pressure limiting or generally control the flow rate of the extinguishing medium (water) vorzuse ^¬ hen.

The invention also relates to a combination of a building part, in particular an outer wall of a building, particularly preferably a facade, with a device according to the above definition, in particular a device for supplying

Extinguishing agent, eg water, to the building part, in particular for Au ^¬ ßenwand, particularly preferably to the facade, with at least one transverse line, which has along its course, outlet openings for the extinguishing agent. The combination according to the invention is characterized by a pressure limiter and / or a flow rate regulator for achieving a controlled release of extinguishing agent at a place of use.
