The invention relates to a method for volume and / or area-specific fighting fire with extinguishing agents in fire-prone areas of buildings and facilities, in which the extinguishing agent of a horizontally arranged in the building piping system with branches and shut-off valves in vertical hollow columns of the building of supplied to an extinguishing agent valve station, and in case of fire by extinguishing agent ejection devices under pressure in specific amount and duration finely atomized or sprayed, the check valves are opened after detecting a fire by detection means to release the extinguishing agent, a trigger signal generated and at the same time triggered an alarm by a control center, issued at least one fire message to a helping body, the extinguishing agent is unlocked and electrical and fire-promoting facilities are turned off,

The invention further relates to a device for carrying out the aforementioned method according to the preamble of claim 20.

State of the art

From DE 10 2006 024 688 B3 a method for volume and / or area-specific fighting fire with extinguishing agent in fire-prone areas of buildings and facilities is known in which the or the extinguishing agent kept a fixed in the building, the fire hazard Passing area piping system with branches and shut-off valves from a water valve station and finely atomized or sprayed in the event of fire by spray nozzles under pressure in specific amount and duration, the shutoff valves are opened after detecting a fire by detection means to release the extinguishing agent and at the same time by a control center Alarm triggered, at least one fire message issued to a helping body, the

Extinguishing agent is released and electrical and fire-promoting systems are switched off, with fire-prone areas surrounded by surveillance areas and self-sufficient control units from a logic matrix for Combating a fire by applying the extinguishing agent are controlled according to the fire. This known method runs in such a way that the area subject to fire is subdivided into individual volume and / or surface elements, the volume and / or surface elements combined into separate monitoring areas and / or zones with autonomous control units respectively assigned to these zones in the monitoring areas Approaching and distributing the extinguishing agent spray areas are formed within the monitoring zones, the fire is detected and located by a responsive to temperature and / or pressure changes, all volume and / or surface elements of a monitoring zone on at least one area enclosing Auslose- and detection means, the Transfers temperature and / or pressure change to the relevant control unit, those monitoring areas are determined, which envelop the fire area, wherein the corresponding control units are locked, the pressure and temperature changes in a control size to open the Loschmit telzufuhr implemented in the fire area and depending on the course of the detected pressure and temperature change those control units are activated, which envelop the fire area.

Although this known method is able to apply finely atomized extinguishing agent volume-specific at the point of origin of the fire with high penetration capacity of the affected room, however escape routes, Durchfahroffnungen in walls and existing technical device are not included in the enveloping areas of the fire and thus in the exposure to extinguishing agent, so that on the one hand the amount of auszubringendem Extinguishing agent is not optimally adapted to the actual needs and on the other hand damage to the goods or the technical device such as forklift o. The like. can not be excluded by the extinguishing agent.

From DE 24 57 061 C3 a shelf storage device with vertical supports and horizontal beams is known, of which at least the supporting vertical supports are formed as a water-filled steel hollow profile rails, which are connected to a water supply line and a water-discharge line, of which one at the top and the other at the bottom and means for generating a flow of water through the vertical supports in case of fire are present.

In the case of fire, the water-carrying horizontal beams are provided with sprinklers, which open in response to temperature increase and distribute the adjacent extinguishing water vertically down directly into the shelf. The issue of extinguishing agent is not adapted to the course of the fire and takes place in such an amount that damage to the stored goods and technical equipment can not be ruled out. This prior art makes the fire extinguishing system directly to the part of the rack system, which is characterized compact, material-intensive, easy to install and unfriendly with functional problems in the management of extinguishing agents such as leaks, susceptibility to corrosion, venting, clogging of the water pipes. Therefore, this known state of the art in the storage and shelving technology could not prevail so far.

Furthermore, this known solution does not contribute to increasing the fire resistance of the enclosure enclosing structure. Further, xst from DE 30 21 335 Al a fire protection system for buildings with sprinklers known that are set at a predeterminable temperature and / or smoke in action and are arranged on at least one medium supplying a fire extinguishing pipe. The sprinkler-carrying pipeline is connected to at least one air duct provided with openings for forming a static-carrying component for example a roof or a ceiling.

This prior art also uses sprinklers with all their disadvantages of uncontrolled release of water after opening for firefighting, wherein the supporting pipeline serves to support a roof or a ceiling. The vertical sockets of the building are not media-leading and are not protected against heat in case of fire.

It is also a structure with a structural member made of metal from DE 93 01 963 Ul known, which has a hollow profile, disposed in the cavity of a fire retardant, the cavity of the structural element liquid keits- and pressure-sealed, the cavity at least partially Water is filled in the liquid state and at least one steam outlet valve is provided on the structural element.

In this known state of the art, steam outlet valves with pivoting steam jet nozzles are arranged on particularly exposed, ie fire-exposed points, which in the event of fire discharge the steam arising from the overheating of the extinguishing agent in the cavity of the support elements and direct it to the supporting structure. However, the prerequisite is that a full fire of the building occurs, which is more likely unlikely, but the fire always emanating from localized places. Incidentally, this solution is not suitable in the building, for example, stored on shelves

Good, goods or the like. to protect effectively against incipient fires.

Another known solution provides a fireproof structure that has water outlet devices and these interconnecting and with a central water supply supply lines, the triggering of the water outlet devices and the central water supply via a fire alarm device. As water outlet spray nozzles are used and arranged along at least a part of the structure and designed so that the water exits as finely dispersed spray droplets or aerosol from them, the edge regions of the exit cone adjacent spray nozzles penetrate each other and in case of fire, lying within their reach parts of the Cover structure in fog.

Also in this known prior art, the fire extinguishing agent is discharged uncontrollably and independently of the fire. Escape routes, openings in walls and technical equipment are covered with extinguishing agent. The extinguishing agent consumption is correspondingly high and damage caused by extinguishing agent can not be prevented.

task

In this prior art, the present invention seeks to provide a method and devices of to improve the type mentioned above for structures such that the thermal load in case of fire can not spread to other areas and escape routes, driveways, openings in walls and parked technical equipment such as operator panels, forklifts, etc., with further minimization of extinguishing agent consumption and the reduction of damage in the event of a fire while at the same time increasing the efficiency of the influence of the extinguishing agent is largely kept free, at the same time a structural compensation between the building and the extinguishing system is achieved.

This object is achieved by a method having the features of claim 1 and the device having the features of claim 20.

Advantageous embodiments of the solution according to the invention can be taken from the subclaims

The solution according to the invention is based on the knowledge to connect the fire detection and / or fire fighting and / or fire control and / or fire control of individual industrial facilities, such as high-bay warehouse functionally with the fire protection safety concept of the plant enclosing structure and fire protection walls of extinguishing agent to the and / or in fire-prone areas.

This is achieved by the fact that at least one dense extinguishing agent wall of spray to prevent the and / or in the fire-prone areas, as they represent, for example, high-bay storage areas Overlap of the fire in areas adjacent to the fire along a spanned between loschmittelfύhrenden supports, monitored by detection spray level is laid within the so-sealed fire source known dynamically adapted to the fire fire fighting methods as described for example in DE 10 2006 024 688 B3 are, can be used. At least one more dense extinguishing agent wall of spray mist is used to protect escape routes, lanes or roads, openings in fire walls and technological equipment within the building along the associated vertical loschmittelfuhrenden supports generated so that an encroachment of the thermal load from the fire in other areas can be safely excluded. The vertical sockets of the building are arranged so that the loschmittelfuhrenden supports around and / or in the fire-prone areas or on the escape routes, lanes or roads, fire walls or technological equipment occupy such a position that the supports and the sockets positioned Lόschmittelauswurfeinrichtungen can span each other by detection means monitored spray levels in which dense in the case of dense and homogeneous Loschmittelwande be created between spray nozzles between the associated nozzle. This is associated with the extraordinary advantage that the extinguishing agent is brought specifically targeted volume-specific, whereby, for example, the escape route, the roads, etc. can be kept free of extinguishing agent. This leads to significant savings of extinguishing agent and to a significant reduction of damage caused by the Extinguishing agent use, at the same time the fire resistance of the building and the technical equipment is increased. Of very significant efficiency is that fixed fire walls can be discontinued, which significantly reduces the construction costs. At the same time, the building can be performed by the large number of vertical sockets used in lightweight construction.

The erfmdungsgemaße device is characterized by the fact that the vertical hollow neck to span the and / or in at least one of the fire protection sections vertical and / or horizontal spray levels, wherein at least the detection means and a control unit for switching on and off the Loschmittelauswurfemrichtungen the relevant Sprühbene and that all spray levels and control units have a common logic matrix for simultaneous draw the foreclosure of the fire or fire-prone area and for the protection and cooling of escape routes, openings m fire walls and technological facilities by Loschmittelwande. This allows, for example, the fire or the fire hazardous area and enclosing the fire areas enclosed by a closed ring of Loschmittelwanden between the nozzle of the adjacent areas of the structure, so that the thermal load from the fire can not get into the adjacent areas.

Further advantages and details will become apparent from the following description with reference to the accompanying drawings. embodiment

The invention will be explained in more detail below using an exemplary embodiment.

Fig. 10 is an illustration of the control unit as a wet variant and

Fig. 11 is a diagram of the inventive method.

Fig. 1 shows a plan view of a building 1, in which the inventive device is integrated. The structure 1 is divided into different fire protection sections. Thus, for example, in building 1, a block storage as fire protection section A and a curvy multi-user system as fire protection section B be placed at ground level, which can be reached by a extending through the building 1 roadway as a fire protection section C located in the building wall door areas as fire protection area D. This classification is exemplary and may well have a different subdivision. The supporting and non-load-bearing vertical pipe 2 of the building 1 are hollow and form lines 3 for the supply of extinguishing agent. With respect to the individual fire protection sections, the sockets 2 are aligned with each other so that they the fire protection sections A, B, C linearly at regular intervals from each other. However, it is also conceivable that the vertical supports 2 subdivide the individual fire protection sections themselves. It only has to be ensured that the supports 2 can form a regular rectilinear grid in and / or around the corresponding fire protection section.

The device according to the invention consists essentially of at least one extinguishing agent container for holding an extinguishing agent, for example water, at least one system for generating the required extinguishing agent pressure of 0.5 to 20 bar, a main valve and valves, all in all to the 4 designated extinguishing valve body belonging to a horizontally in any plane of the structure, for example near the roof, inserted pipe system 5 with parallel lines 6 for supplying extinguishing agent in the lines 3 of the vertical supports 2, control units 7, which are connected to the pipe system 5 and the vertical supports 2 , Extinguishing agent ejection means 8 for discharging extinguishing agent, detection means 9 and an unnamed fire alarm panel with an integrated logic matrix 10th

The extinguishing valve body 4 is connected via a main line 11 to the pipe system 5, which passes through the structure 1, for example, in the vicinity of the roof structure. The pipe system 5 may be formed as a ring or box line 12 which is meshed horizontally by the parallel lines 6.

To the ring or box line 12 and / or the parallel lines 6 are -wie Fig. 2 and 3 show- the vertical supports 2 connected. Each vertical support 2 is connected via a short horizontal branch line 13 to the control unit 7.1 ... 7.n, which connects via a vertical branch line 14 with pipe bend 15 in the ring or box line 12.

The vertical supports 2 are preferably made of steel pipe and are provided at regular intervals with sleeves 16 with internal thread, which are cohesively, for example, by welding, inserted into the tubular jacket of the supports. Into the sleeves 16 are the extinguishing agent ejection devices 8, preferably spray nozzles, liquid and pressure-tight screwed and aligned according to the desired spraying direction. Of course, it is also possible to use vertical supports 2 made of waterproof concrete, without departing from the invention.

In Figs. 4a to 4d is the distribution of the sleeves

16 shown on the circumference of the vertical supports 2, for example.

The screwed into the sleeves 16

Extinguishing agent ejection 8 throw out such an amount of extinguishing agent, which give a homogeneous and sufficiently thick extinguishing agent wall of extinguishing agent mist between the supports 2, to achieve the required fire resistance for the corresponding fire protection section A to D according to a fire wall. The distribution and the number of extinguishing agent ejection devices 8 are determined by the dimensions of the surface to be protected, the predetermined fire resistance time and the necessary volume of the extinguishing agent mist to be generated. For an area of For example, 100 m ² , a total of 4 Loschmittelauswurfeinπchtungen 8 have been found to produce a 1.5 m thick and homogeneous Loschmittelwand from Loschmittelnebel sufficient. It may, for example, only two or up to six Loschmittelauswurfemrichtungen 8 are provided, which are able to eject the extinguishing agent in different directions depending on the requirements. As Loschmittelauswurfemrichtungen 8 are Sprühwasserdusen, Femspruhdusen, Vollkegelusen with upstream filter or controllable nozzles equally suitable.

The vertical distance of the Loschmittelauswurfemrichtungen 8 is suitably matched with the dimensions of the shelf heights of erected in the fire protection section A or B rack warehouse.

5a and 5b show variants of the anchoring of the vertical support 2 on or in the

Bottom plate 17 of the structure 1. In the event that the vertical nozzle 2 has risen on the bottom plate 17, the support 2 is closed by a foot plate 18 liquid-tight, which is anchored by means of threaded rods 19 in a cage in the bottom plate 17. The vertical support 2 has near its base plate 18 a sleeve

20 for receiving a non-illustrated Entluftungs- and emptying device. If the vertical support 2 is anchored directly in the bottom plate 17, an emptying device 46 with drainage must be provided

(see Fig. 5b).

At each control unit 7.1 ... 7.n can be a detection means 9, for example, a hydrothermal Tubing with tissue reinforcement, be connected, which in the plane defined by the regularly spaced apart from each other stubs 2 vertical planes El. En zigzag formally laid. The hose is, for example, under a control pressure of 0.5 to 20, preferably 3.0 to

4.0 bar, which is generated by a foreign medium such as a gas, preferably compressed air, or a liquid, preferably water.

But it is also possible instead of the hydrothermal hose heat line detectors or, for example, directly use the line 3 of the nozzle 2 monitoring pressure monitor 47. The pressure monitors 47 are then connected to the logic matrix 10, which activates the corresponding control units 7.1... 7.n (see FIG. 3). FIG. 6 shows the laying of the hydrothermal hose in these vertical planes El ... E.nn spanning the fire protection sections.

The hydrothermal hose operates as a line-shaped thermo-detector, which is acted upon by a control pressure of 0.5 to 20 bar, here 4 bar. The control medium may be gaseous, preferably compressed air, or else liquid, preferably water.

As soon as a temperature increase due to thermal load due to flame action takes place in a plane E.L.E.n, this leads to the pressure increase of the control medium in the hose, which causes a bursting of the hose and thus a pressure drop of the control medium. This pressure drop affects the affected control unit

7.1 7.n, which triggers the opening of the extinguishing agent supply and the access of the extinguishing agent under pressure up to 16 bar in the vertical port 2 to the corresponding Loschmittelauswurfeinrichtungen 8 releases.

The control unit 7.1 ... 7.n is further connected to the logic array 10 of the fire panel and signals the draw of the Loschmittelauswurfeinrichtungen 8 for generating the water wall, for example in the plane El. The logic matrix 10 determines the further levels E.n associated with the corresponding fire protection section A and activates the control units 7.n belonging to these levels, which in turn cause the opening of the extinguishing agent supply to the affected planes E.n. The corresponding fire protection section is thus sealed off, so that the fire can not spread over the adjacent sections of the structure 1.

The fire resistance of the individual sections can be further increased if at least one further detection means connected to the logic matrix 10, such as a smoke detector, is provided within the fire protection sections. As soon as this detects a risk of fire, the logic matrix 10 controls the control units 7. N belonging to the fire source which trigger the extinguishing agent supply to generate the vertical and / or horizontal extinguishing agent walls in the spray levels surrounding the fire between the vertical connecting pieces 2. Expediently, the at least one further detection means can be fastened in the roof area of the building 1 above the head of the building, for example the block storage. Of course, there are others besides the smoke detector Detecting means such as mechanical, hydraulic, thermal, optical systems, such as sprinkler systems suitable.

But it also belongs to the invention, when the entire along the levels El ... E.n sealed by Loschmittelwande block storage is additionally monitored by a separate Loschanlage, which is connected to the pipe system 5. The structure of this extinguishing system can for example correspond to those according to DE 10 2006 024 088 B3 or else be a commercially available sprinkler system.

Figs. 7 and 8 show the structure of the control unit 7.1 to 7.n as a dry variant. The control unit 7.1..7.n consists essentially of a provided with an input and output line 21 and 22 diaphragm valve 23 and a pilot valve 24. The diaphragm valve 23 has a diaphragm chamber 25, in which a membrane 26 between the housing 27 of the diaphragm valve 23 and a diaphragm chamber 25 final lid 28 is fixed. In the closed state, the membrane 26 is full on the valve seat 29 of the diaphragm valve 23 and blocks the Loschmittelzutritt in the Abstromkammer 30 of the diaphragm valve 23rd

The lid 28 carries a port 31 for a compressed air hose 32 which is connected to a compressed air source, not shown, and the pilot valve 24. The compressed air source prints the diaphragm 26 on its valve seat 29 and acts on the connected to the pilot valve 24, end by an end piece 33 closed hydrothermal hose. Compressed air hose and Hydrothermal hose are secured by a check valve 34 from each other. The hose can be shut off by a ball valve 35 with respect to the pilot valve 24. Likewise, it is possible with a ball valve 36 to shut off the extinguishing agent supply to the diaphragm valve 23.

Once the pressure drop has occurred in the tube, the membrane 26 is relieved and dissolves due to the pending Löschmitteldruckes from its valve seat 29. Through the incorporated in the membrane 26 nozzle 37 and fluid channels

38 between pilot valve 24 and outflow chamber 30 escapes the still in the diaphragm chamber 25 and the pilot valve 24 located air, so that a rapid response of the

Diaphragm valve 23 is ensured.

The extinguishing agent passes through the diaphragm chamber 25 in the outflow chamber 30 and flows through the vertical supports 2 to the extinguishing agent ejection devices 8, from which the extinguishing agent can be misted in the planes El ... En to emerge to form the extinguishing agent wall.

In the pilot valve 24 or port 31, a pressure sensor 39 is mounted, which detects the pressure drop and via a connecting line 40 a converter 41 which communicates with the main water valve of the extinguishing valve body 4 via a control unit in communication. It opens the main water valve when the signal is present.

Instead of the diaphragm valve 23, a solenoid valve 42 (see Fig. 9) in the control unit 7.1 ... 7.n come to use. The control of the valve is detected in this case by a pressure drop detecting sensor 39 or initiated by the pressure switch 47, which causes the trigger mechanism 43 in the firing chamber 44 of the solenoid valve 42 to open the valve seat and release the pending extinguishing agent.

Fig. 10 shows the control unit 7.1 ... 7.n as a wet variant. In this case, no sensor 39 for detecting the pressure drop and driving the main water valve is required. The extinguishing agent is without additional shut-off in the diaphragm chamber 25 and presses the membrane sealingly on the valve seat 29. The further structure corresponds to the control unit 7.1. according to FIG. 7.

FIG. 11 illustrates the sequence of the method according to the invention. The structure 1 is subdivided into several fire protection sections A to D according to the present conditions. In the example there is a section A for a block storage, a section B for a curved multi-station system, a section C for the sections A and B connecting lane for the transport of storage goods and a section D for gates for the entrance and exit in and from the building 1.

The sections A to D are each surrounded by vertical spray levels El .... En, which are spanned between the vertical supports 2 of the structure 1. Each of these spray levels El..En is traversed by detection means 9 such as a heat line detector and is monitored for temperature and pressure change and controlled so that each section A to D separated by itself and to a certain extent by a virtual fire wall in the form of an extinguishing agent wall of spray is lockable. Each spray level is assigned to at least one control unit 7.1... 7.n, which is connected to the logic matrix 10 of the fire panel. If a pressure drop due to a fire in one of the sections A to D is detected by the detection means 9 in a spray level El..En, the pressure sensor 39 forwards this information to the logic matrix 10 after conversion into a digital signal. It processes the signal in which the planes El..En and supports 2 belonging to the affected section are determined. The logic matrix 10 opens via a control unit designed as a solenoid valve main valve of the extinguishing agent valve station 4 and controls the affected control units 7.1 ... 7.n for the purpose of generating vertical Loschmittelwänden in the levels El..En between the supports 2 automatically. The fire-endangered section is then surrounded on all sides by a homogeneous, dense medium wall of extinguishing agent mist, which fulfills the function of a fire protection wall.

If the fire does not start in the vicinity of one of the monitored levels El..En, but in the interior of the set up, for example in Section A block warehouse, the fire or the fire hazard is arranged by at least one further overhead of the block bearing, with the Logic matrix 10 connected detection means 45, such as smoke detectors detected and transmitted as a signal to the logic array 10. As previously described, the logic matrix 10 initiates the opening of the main valve of the extinguishing-agent valve station 4 and the activation of the corresponding control units 7.1... 7n for generating the extinguisher walls along the affected section. After the corresponding section is enclosed by extinguishing agent walls, of course, within the section, the fire or the fire hazard can be controlled volume-specific. It is of particular advantage if the volume-specific control of the fire is carried out according to the method of DE 10 2006 024 688 B3.

However, the logic matrix 10 can also be triggered by a hotline detector and / or automatic detectors. It can also be activated manually and can be reset by a reset. In addition to water, other extinguishing agents such as inert gases, chemical gases, powders or foams can be used as extinguishing agents. It is understood that the device according to the invention for carrying out the method is then adapted to the corresponding extinguishing agent.

The solution according to the invention leads to the extraordinary advantage that the structure 1 can be built by the large number of vertical supports 2 in lightweight construction, so that saves considerable amounts of building materials and at the same time the safety and fire resistance of the building are significantly increased.

In addition, the solution according to the invention makes it possible to involve classical firefighting methods, in which the vertical extinguishing agent-carrying supports 2, water extraction devices, such as fittings or hydrants, can be easily connected to the corresponding fire-fighting devices.

So that corrosion and aging in the device according to the invention can be prevented, is the Further envisaged that suitable means for reducing the corrosion are added to the extinguishing agent.
