Aus der DE 10 2006 024 688 B3 ist ein Verfahren zum volumen- und/oder flächenspezifischen Bekämpfen von Feuer mit Löschmittel in brandgefährdeten Bereichen von Bauten und Anlagen bekannt, bei dem die oder das Löschmittel bereitgehalten, einem im Bauwerk festinstallierten, den brandgefährdeten Bereich durchziehenden Rohrleitungssystem mit Abzweigungen und Absperrventilen von einer Wasserventilstation zugeführt und im Brandfall durch Sprühdüsen unter Druck in spezifischer Menge und Dauer fein vernebelt oder versprüht wird, wobei die Absperrventile nach Detektieren eines Feuers durch Detektionsmittel zur Freigabe des Löschmittels geöffnet werden und zugleich durch eine Steuerzentrale ein Alarm ausgelöst, mindestens eine Brandmeldung an eine Hilfe leistende Stelle ausgegeben, das Löschmittel freigeschaltet wird sowie elektrische und brandfördernde Anlagen abgeschaltet werden, wobei brandgefährdete Bereiche durch Überwachungsbereiche umhüllt und autarke Steuereinheiten von einer Logikmatrix zur Bekämpfung eines Feuers durch Ausbringen des Löschmittels entsprechend dem Brandverlauf angesteuert werden.
Dieses bekannte Verfahren läuft so ab, dass der brandgefährdete Bereich in einzelne Volumen- und/oder Flächenelemente aufgeteilt, die Volumen- und/oder Flächenelemente zu separaten Überwachungsbereiche und/oder - zonen mit jeweils diesen Zonen getrennt zugeordneten autarken Steuereinheiten zusammengefasst, in den Überwachungsbereichen durch Heranführen und Verteilen des Löschmittels Sprühbereiche ausgebildet werden, innerhalb der Überwachungszonen das Feuer erfasst und geortet wird durch ein auf Temperatur- und/oder Druckänderungen ansprechbares, alle Volumen- und/oder:Flächenelemente einer Überwachungszone an wenigstens einer Fläche umschließendes Auslöse- und Detektionsmittel, das die Temperatur- und/oder Druckänderung an die betreffende Steuereinheit weiterleitet, diejenigen Überwachungsbereiche bestimmt werden, die den Brandbereich umhüllen, wobei die entsprechenden Steuereinheiten verriegelt werden, die Druck- und Temperaturänderungen in eine Steuergröße zum Öffnen der Löschmittelzufuhr in den Brandbereich umgesetzt und je nach Verlauf der festgestellten Druck- und Temperaturänderung diejenigen Steuereinheiten aktiviert werden, die den Brandbereich umhüllen.From the DE 10 2006 024 688 B3 is a method for volume and / or surface specific fighting fire with extinguishing agent in fire-prone areas of buildings and facilities is known in which the or the extinguishing kept ready fed to a permanently installed in the building, the fire-prone area by pulling piping with branches and shut-off valves from a water valve station and in the case of fire is atomized or sprayed by spray nozzles under pressure in specific quantity and duration, the shut-off valves being released after detection of a fire by detection means opened at the same time by a control center an alarm, issued at least one fire message to a helping body, the extinguishing agent is unlocked and electrical and fire-promoting facilities are switched off, fire-prone areas surrounded by surveillance areas and self-sufficient control units of a logic matrix to combat a Fire are triggered by applying the extinguishing agent according to the fire.
This known method proceeds in such a way that the fire-endangered area is subdivided into individual volume and / or area elements, the volume and / or area elements combined into separate monitoring areas and / or zones with autonomous control units respectively assigned to these zones in the monitoring areas In the monitoring zones, the fire is detected and located by a temperature-sensitive and / or pressure-responsive, all volume and / or surface elements of a surveillance zone on at least one area enclosing triggering and detection means, the the temperature and / or pressure change to the relevant control unit passes, 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 variable for Opening the extinguishing agent supply 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.

Dieses bekannte Verfahren vermag zwar feinvernebeltes Löschmittel volumenspezifisch am Entstehungsort des Brandes mit hohem Durchdringungsvermögen des betroffenen Raumes auszubringen, jedoch werden Fluchtwege, Durchfahröffnungen in Wänden und vorhandenes technisches Gerät in die umhüllenden Bereiche des Brandherdes und damit in die Beaufschlagung mit Löschmittel nicht einbezogen, so dass einerseits die Menge an auszubringendem Löschmittel nicht optimal an den wirklichen Bedarf angepasst ist und andererseits Schäden an den Waren bzw. am technischen Gerät wie Stapler o. dgl. durch das Löschmittel nicht auszuschließen sind.Although this known method is able to apply finely atomized extinguishing agent volume-specific at the place of fire with high penetration capacity of the affected room, however, escape routes, passage openings in walls and existing technical equipment are not included in the enveloping areas of the fire and thus in the exposure to extinguishing agents, so that on the one hand the amount of extinguishing agent to be applied is not optimally adapted to the actual requirements and, on the other hand, damage to the goods or to the technical equipment such as forklifts or the like can not be ruled out by the extinguishing agent.

Aus der DE 24 57 061 C3 ist eine Regallagereinrichtung mit Vertikalstützen und Horizontalträgern bekannt, von denen mindestens die tragenden Vertikalstützen als wassergefüllte Stahl-Hohlprofilschienen ausgebildet sind, die an eine Wasser-Zuflussleitung sowie eine Wasser-Abflussleitung angeschlossen sind, von denen die eine oben und die andere unten einmünden und Mittel zur Erzeugung eines Wasserdurchflusses durch die Vertikalstützen im Brandfall vorhanden sind.
Für den Brandfall sind die wasserführenden Horizontalträger mit Sprinklern versehen, die bei Ansprechen infolge Temperaturerhöhung öffnen und das anliegende Löschwasser senkrecht nach unten direkt in das Regal verteilen. Die Löschmittelausgabe wird nicht an den Brandverlauf angepasst und erfolgt in einer solchen Menge, dass Schäden am Lagergut und technischem Gerät nicht auszuschließen sind.
Dieser bekannte Stand der Technik macht die Feuerlöschanlage direkt zum Bestandteil der Regalanlage, die dadurch kompakter, materialintensiver, montageunfreundlicher und mit funktionellen Problemen im Löschmittelmanagement wie Dichtheit, Korrosionsanfälligkeit, Entlüftung, Verstopfungen der wasserführenden Leitungen usw. behaftet ist. Deshalb konnte sich dieser bekannte Stand der Technik in der Lager-und Regaltechnik bisher nicht durchsetzen.
Des Weiteren trägt diese bekannte Lösung nicht zur Erhöhung des Brandwiderstandes des die Regalanlage umhüllenden Bauwerks bei.From the 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 water-filled steel hollow profile rails, which are connected to a water supply line and a water-discharge line, one of which open at the top and the other bottom and means for Generation of a water flow 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 known prior art makes the fire extinguishing system directly to the part of the rack system, which thereby compact, material-intensive, easy to install and with functional problems in the management of extinguishing agents such as tightness, susceptibility to corrosion, ventilation, blockages of the water-carrying lines, etc. is affected. Therefore, this known state of the art in the storage and shelf technology could not prevail so far.
Furthermore, this known solution does not contribute to increasing the fire resistance of the enclosure enclosing structure.

Die die Sprinkler tragende Rohrleitung ist mindestens einer mit Öffnungen versehenen Luftleitung zur Ausbildung eines statisch tragenden Bauelements für z.B. ein Dach oder eine Decke verbunden.
Auch dieser bekannte Stand der Technik setzt Sprinkler mit all ihren Nachteilen einer unkontrollierten Wasserabgabe nach dem Öffnen zur Brandbekämpfung ein, wobei die tragende Rohrleitung zur Auflagerung eines Daches oder einer Decke dient. Die Vertikalstützen des Bauwerks sind nicht medienführend und werden auch nicht gegen Hitze bei Brand geschützt.Furthermore, from the DE 30 21 335 A1 a fire protection system for buildings with sprinklers, which 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 pipeline carrying the sprinklers is connected to at least one air duct provided with openings for forming a statically supporting component for eg a roof or a ceiling.
Also, this known prior art uses sprinklers with all their disadvantages of uncontrolled release of water after opening for fire fighting, the supporting pipe is used to support a roof or a ceiling. The vertical supports of the structure are not media leading and are not protected against heat in case of fire.

Es ist auch ein Tragwerk mit einem Tragwerkselement aus Metall aus der DE 93 01 963 U1 bekannt, welches ein Hohlprofil aufweist, in dessen Hohlraum ein Brandschutzmittel angeordnet, wobei der Hohlraum des Tragwerkselements flüssigkeits- und druckdicht abgeschlossen, der Hohlraum zumindest teilweise mit Wasser im flüssigem Zustand gefüllt und an dem Tragwerkselement wenigstens ein Dampfauslassventil vorgesehen ist.
Bei diesem bekannten Stand der Technik werden an besonders exponierten, d.h. brandgefährdeten Stellen Dampfauslassventile mit schwenkbaren Dampfstrahldüsen angeordnet, die im Brandfall den aus der Überhitzung des Löschmittels im Hohlraum der Tragelemente entstehenden Dampf ablassen und auf das Tragwerk richten. Voraussetzung ist aber, dass ein Vollbrand des Gebäudes eintritt, was eher unwahrscheinlich ist, sondern der Brand immer von örtlich begrenzten Stellen ausgeht. Im Übrigen ist diese Lösung nicht geeignet, im Bauwerk, beispielsweise in Regalen gelagertes Gut, Waren o.dgl. wirksam vor Entstehungsbränden zu schützen.It is also a structure with a structural element made of metal from the DE 93 01 963 U1 known, which has a hollow profile, arranged in the cavity of a fire retardant, wherein the cavity of the structural member liquid and pressure sealed completed, the cavity at least partially filled with water 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-prone areas, which in case 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 rather unlikely, but the fire always emanating from localized places. Incidentally, this solution is not suitable in the building, for example, shelves stored goods, goods or the like. to protect effectively against incipient fires.

Eine weitere bekannte Lösung sieht ein brandschutzgerechtes Tragwerk vor, das Wasseraustrittsvorrichtungen und diese untereinander und mit einer zentralen Wasserzuführeinrichtung verbindenden Versorgungsleitungen aufweist, wobei die Auslösung der Wasseraustrittsvorrichtungen und der zentralen Wasserzuführeinrichtung über eine Brandmeldeeinrichtung erfolgt. Als Wasseraustrittsvorrichtungen werden Sprühdüsen verwendet und diese entlang zumindest eines Teils des Tragwerks so angeordnet und ausgelegt, dass das Wasser als fein verteilte Sprühtröpfchen oder Aerosol aus ihnen austritt, die Randbereiche der Austrittskegel benachbarter Sprühdüsen sich gegenseitig durchdringen und im Brandfall die in ihrer Reichweite liegenden Teile des Tragwerks in Nebel einhüllen.
Auch bei diesem bekannten Stand der Technik wird das Feuerlöschmittel unkontrolliert und unabhängig vom Brandverlauf ausgebracht. Fluchtwege, Öffnungen in Wänden und technisches Gerät werden flächendeckend mit Löschmittel beaufschlagt. Der Löschmittelverbrauch ist entsprechend hoch und durch Löschmittel verursachte Schäden können nicht verhindert werden.
Des Weiteren sind aus der CN 2 535 468 Y und FR 2 336 641 A1 hohle Tragmetallkonstruktionen in einem Bauwerk bekannt, in denen Wasser zum Kühlen, Heizen und zur Feuerbekämpfung geführt wird.Another known solution provides a fire-resistant structure that has water outlet devices and these with each other and with a central water supply connecting 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 device are applied to surface-wide with extinguishing agent. The extinguishing agent consumption is correspondingly high and damage caused by extinguishing agent can not be prevented.
Furthermore, from the CN 2 535 468 Y and FR 2 336 641 A1 hollow Tragmetallkonstruktionen known in a building in which water for cooling, heating and fire fighting is performed.

Aufgabenstellungtask

Bei diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Verfahren und Vorrichtungen der eingangs genannten Art für bauliche Anlagen derart zu verbessern, dass die thermische Belastung im Brandfall nicht auf andere Bereiche übergreifen kann und Fluchtwege, Fahrwege, Öffnungen in Wänden und abgestelltes technisches Gerät wie Bediengeräte, Stapler usw. unter weiterer Minimierung des Löschmittelverbrauchs und der Herabsetzung von Schäden im Brandfall bei gleichzeitiger Erhöhung der Wirtschaftlichkeit vom Einfluss des Löschmittels weitgehend freigehalten wird, wobei zugleich eine bautechnische Kompensation zwischen dem Bauwerk und der Löschanlage erreicht wird.In this prior art, the present invention seeks to improve a method and devices of 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 Device such as control panels, forklifts, etc., while further minimizing the consumption of extinguishing agents and reducing the damage in case of fire while increasing the efficiency largely exempt from the influence of the extinguishing agent, at the same time a structural compensation between the building and the extinguishing system is achieved.

Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 1 und der Vorrichtung mit den Merkmalen des Anspruches 15 gelöst.This object is achieved by a method having the features of claim 1 and the device having the features of claim 15.

Vorteilhafte Ausgestaltungen der erfindungsgemäßen Lösung sind den Unteransprüchen entnehmbar.Advantageous embodiments of the solution according to the invention can be taken from the subclaims.

Die erfindungsgemäße Lösung geht von der Erkenntnis aus, die Branderkennung und/oder Brandbekämpfung und/oder Brandniederhaltung und/oder Brandkontrolle einzelner industrieller Anlagen, beispielsweise Hochregallager funktionell mit dem brandschutztechnischen Sicherheitskonzept des die Anlage umhüllenden Bauwerks zu verbinden und Brandschutzwände aus Löschmittel um die und/oder in den brandgefährdenden Bereich/e zu errichten.The solution according to the invention is based on the knowledge of fire detection and / or fire fighting and / or fire control and / or fire control of individual industrial facilities, such as high-bay warehouse functionally connected to the fire protection safety concept of the plant enclosing structure and fire protection walls of extinguishing agent to and / or into the fire-endangered area / s.

Dies wird dadurch erreicht, dass mindestens eine weitere dichte Löschmittelwand aus Sprühnebel zum Schutz von Fluchtwegen, Fahrbahnen oder -wegen, Öffnungen in Brandschutzwänden und um technologischen Einrichtungen innerhalb des Bauwerks entlang der diesen zugeordneten vertikalen löschmittelführenden Stützen erzeugt wird, wobei folgende Schritte ausgeführt werden:

  1. a) Aufteilen der löschmittelführenden Stützen des Bauwerks auf die brandgefährdeten Bereiche, Fluchtwege, Fahrbahnen oder -wege, Öffnungen in Brandschutzwänden und technischem Gerät,
  2. b) Zusammenfassen der brandgefährdeten Bereiche und löschmittelführende Stützen zu großvolumigen Überwachungssektionen mit jeweils diesen Sektionen zugeordneten Löschmittelauswurfeinrichtungen,
  3. c) Ausbilden der Ebenen E1...En für Löschmittelwände zwischen den zum Brandherd bzw. brandgefährdeten Bereich gehörenden vertikalen Stützen durch Ansteuern der zur jeweiligen Überwachungssektion gehörenden Löschmittelauswurfeinrichtungen mit einer Steuereinheit,
  4. d) Erfassen und Orten des Feuers innerhalb der Überwachungssektion durch Detektionsmittel, die eine Temperatur-, Rauch- und/oder Druckänderung an die auslösenden Steuereinheiten und die Logikmatrix weiterleiten,
  5. e) Bestimmen der vertikalen Stützen, zwischen denen die vertikale und/oder horizontale Löschmittelwand erzeugt werden soll, wobei die entsprechenden Steuereinheiten verriegelt werden,
  6. f) Umsetzen der Temperatur-, Rauch- und/oder Druckänderung gemäß Schritt d) in eine Steuergröße und Aktivieren der den vertikalen Stützen zugeordneten Steuereinheiten zum Öffnen und/oder Schließen der Löschmittelauswurfeinrichtungen für das Erzeugen der Löschmittelwand.
Die vertikalen lasttragenden oder nichtlasttragenden Stützen des Bauwerks werden dabei so angeordnet, dass dieselben an den Fluchtwegen, Fahrbahnen- oder -wegen, Brandschutzwänden oder technologischen Einrichtungen solch eine Lage einnehmen, dass die Stützen und die an den Stützen positionierten Löschmittelauswurfeinrichtungen untereinander durch Detektionsmittel überwachte Sprühebenen aufspannen können, in denen im Auslösungsfall dichte und homogene Löschmittelwände aus Sprühnebel zwischen den zugeordneten Stützen erzeugt werden.
Dies ist mit dem außerordentlichen Vorteil verbunden, dass das Löschmittel volumenspezifisch gezielt zum Einsatz gebracht wird, wodurch beispielsweise der Fluchtweg, die Fahrbahnen usw. frei von Löschmittel gehalten werden können. Dies führt zu erheblichen Einsparungen an Löschmittel und zu einer maßgeblichen Reduzierung von Schäden durch den Löschmitteleinsatz, wobei zugleich der Brandwiderstand des Gebäudes und der technischen Anlagen erhöht wird.
Von ganz wesentlicher Effizienz ist, dass feste Brandschutzwände in Fortfall gebracht werden können, was die Baukosten erheblich senkt. Gleichzeitig kann auch das Bauwerk durch die Vielzahl der eingesetzten vertikalen Stützen in Leichtbauweise ausgeführt werden.This is accomplished by providing at least one further dense extinguishing wall of spray to protect escape routes, lanes or roads, openings in fire walls, and technological equipment within the structure along its associated vertical extinguishing means-carrying columns, the following steps being carried out:
  1. a) dividing the extinguishing agent-carrying supports of the structure into fire-endangered areas, escape routes, carriageways or lanes, openings in fire-protection walls and technical equipment,
  2. b) combining the fire-prone areas and extinguishing agent-carrying columns to large-volume monitoring sections with extinguishing agent ejection devices assigned to each of these sections,
  3. c) forming the planes E1 ... En for extinguishing agent walls between the vertical supports belonging to the fire area or fire-endangered area by activating the extinguishing agent ejection devices belonging to the respective monitoring section with a control unit,
  4. d) detecting and locating the fire within the monitoring section by detection means comprising a Forward temperature, smoke and / or pressure change to the triggering control units and the logic matrix,
  5. e) determining the vertical supports between which the vertical and / or horizontal extinguishing agent wall is to be created, whereby the corresponding control units are locked,
  6. f) converting the temperature, smoke and / or pressure change according to step d) into a control variable and activating the vertical supports associated control units for opening and / or closing the extinguishing agent ejection devices for generating the extinguishing agent wall.
The vertical load-bearing or non-load-bearing columns of the structure are arranged so that they occupy such a position on escape routes, lanes or paths, fire walls or technological equipment that the columns and the extinguishing agent ejection devices positioned on the columns span spray levels monitored by detection means can be generated in which, in the event of triggering dense and homogeneous extinguishing agent walls of spray between the associated columns.
This is associated with the extraordinary advantage that the extinguishing agent is brought specifically targeted volume-specific, whereby, for example, the escape route, the lanes, 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 use of extinguishing agents, at the same time increasing the fire resistance of the building and the technical equipment.
It is very important that fixed fire protection walls can be eliminated, which considerably reduces the construction costs. At the same time, the building can be carried out by the large number of vertical supports used in lightweight construction.

Die erfindungsgemäße Vorrichtung zeichnet sich dadurch aus, dass die vertikalen löschmittelführenden Stützen, Löschmittelauswurfeinrichtungen und Detektionsmittel an Fluchtwegen, Fahrbahnen oder -wegen, Öffnungen an Brandschutzwänden oder technologischen Einrichtungen des Bauwerkes positioniert sind, wobei die Logikmatrix so konfiguriert ist, dass sie unter Durchführung der Schritte a) bis f) des Anspruches 1 eine weitere Löschmittelwand aus Sprühnebel zum Schutz und Kühlen der Fluchtwege, Fahrbahnen oder -wegen, Öffnungen an Brandschutzwänden oder technologischen Einrichtungen innerhalb des Bauwerkes zwischen den zugeordneten Stützen legt.The device according to the invention is characterized in that the vertical extinguishing agent-carrying supports, extinguishing agent ejection means and detection means are positioned on escape routes, lanes or paths, openings on fire walls or technological equipment of the building, wherein the logic matrix is configured to perform the steps a ) to f) of claim 1 another extinguishing agent wall of spray to protect and cool the escape routes, lanes or roads, openings on fire walls or technological equipment within the building between the associated supports sets.

Weitere Vorteile und Einzelheiten ergeben sich aus der nachfolgenden Beschreibung unter Bezugnahme auf die beigefügten Zeichnungen.Further advantages and details will become apparent from the following description with reference to the accompanying drawings.

Die Fig. 1 zeigt einen Grundriss eines Bauwerks 1, in das die erfindungsgemäße Vorrichtung integriert ist. Das Bauwerk 1 ist in unterschiedliche Brandschutzsektionen eingeteilt. So kann beispielsweise im Bauwerk 1 ein Blocklager als Brandschutzsektion A und ein kurvengängiges Mehrplatzsystem als Brandschutzsektion B ebenerdig aufgestellt sein, die von einer sich durch das Gebäude 1 erstreckenden Fahrbahn als Brandschutzsektion C über in der Bauwerkswand befindliche Torbereiche als Brandschutzbereich D erreichbar sind. Diese Einteilung ist beispielhaft und kann durchaus eine andere Unterteilung aufweisen.
Die tragenden und nichttragenden vertikalen Stützen 2 des Bauwerks 1 sind hohl ausgeführt und bilden Leitungen 3 zur Zuführung von Löschmittel. In Bezug auf die einzelnen Brandschutzsektionen sind die Stützen 2 so zueinander ausgerichtet, dass sie die Brandschutzsektionen A, B, C geradlinig in regelmäßigen Abständen voneinander umgrenzen.
Es ist aber auch denkbar, dass die vertikalen Stützen 2 die einzelnen Brandschutzsektiönen selbst unterteilen. Es muss nur gewährleistet sein, dass die Stützen 2 untereinander ein regelmäßiges geradliniges Raster in und/oder um die entsprechende Brandschutzsektion bilden können.The Fig. 1 shows a plan of a building 1, in which the device according to the invention is integrated. The structure 1 is divided into different fire protection sections. Thus, for example, in the building 1, a block storage as fire protection section A and a curved multi-user system 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 load-bearing and non-structural vertical supports 2 of the structure 1 are hollow and form lines 3 for the supply of extinguishing agent. With respect to the individual fire protection sections, the supports 2 are aligned with each other such that they circumscribe the fire protection sections A, B, C in a straight line at regular intervals.
However, it is also conceivable that the vertical supports 2 subdivide the individual fire protection sectiones 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.

Die erfindungsgemäße Vorrichtung besteht im Wesentlichen aus mindestens einem Löschmittelbehälter zum Vorhalten eines Löschmittels, beispielsweise Wasser, mindestens einem System zum Erzeugen des erforderlichen Löschmitteldruckes von 0,5 bis 20 bar, einem Hauptventil und Ventilen, die insgesamt zu der mit 4 bezeichneten Löschmittelventilstation gehören, einem horizontal in eine beliebige Ebene des Bauwerks, beispielsweise nahe des Daches, eingefügten Rohrsystems 5 mit Parallelleitungen 6 zum Zuführen von Löschmittel in die Leitungen 3 der vertikalen Stützen 2, Steuereinheiten 7, die am Rohrsystem 5 und an den vertikalen Stützen 2 angeschlossen sind, Löschmittelauswurfeinrichtungen 8 zum Ausbringen von Löschmittel, Detektionsmitteln 9 und einer nichtbezeichneten Brandmeldezentrale mit einer integrierten Logikmatrix 10.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 medium pressure of 0.5 to 20 bar, a main valve and valves, which belong to the total designated 4 extinguishing valve body, a Horizontally in any plane of the structure, such as 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 8th for discharging extinguishing agent, detection means 9 and an unnamed fire control panel with an integrated logic matrix 10.

Die Löschmittelventilstation 4 ist über eine Hauptleitung 11 mit dem Rohrsystem 5 verbunden, das das Bauwerk 1, beispielsweise in Nähe der Dachkonstruktion durchzieht. Das Rohrsystem 5 kann als Ring- oder Kastenleitung 12 ausgebildet sein, die durch die Parallelleitungen 6 horizontal vermascht ist.The extinguishing agent valve station 4 is connected via a main line 11 with 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.

An die Ring- oder Kastenleitung 12 und/oder die Parallelleitungen 6 sind -wie Fig. 2 und 3 zeigen- die vertikalen Stützen 2 angeschlossen. Jede vertikale Stütze 2 ist über eine kurze horizontale Abzweigleitung 13 mit der Steuereinheit 7.1...7.n verbunden, die über eine vertikale Abzweigleitung 14 mit Rohrbogen 15 in die Ring- oder Kastenleitung 12 einbindet.To the ring or box line 12 and / or the parallel lines 6 are-like 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.

Die vertikalen Stützen 2 bestehen vorzugsweise aus Stahlrohr und sind in regelmäßigen Abständen mit Muffen 16 mit Innengewinde versehen, die in den Rohrmantel der Stützen stoffschlüssig, beispielsweise durch Schweißen, eingesetzt sind. In die Muffen 16 sind die Löschmittelauswurfeinrichtungen 8, vorzugsweise Sprühdüsen, flüssigkeits- und druckdicht eingeschraubt und entsprechend der gewünschten Sprührichtung ausgerichtet. Natürlich ist es auch möglich, vertikale Stützen 2 aus wasserdichtem Beton einzusetzen, ohne die Erfindung zu verlassen.The vertical supports 2 are preferably made of steel tube 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 den Fig. 4a bis 4d ist die Verteilung der Muffen 16 am Umfang der vertikalen Stützen 2 beispielsweise gezeigt. Die in die Muffen 16 eingeschraubten Löschmittelauswurfeinrichtungen 8 werfen eine solche Löschmittelmenge aus, die eine homogene und ausreichend dicke Löschmittelwand aus Löschmittelnebel zwischen den Stützen 2 ergeben, um den geforderten Feuerwiderstand für die entsprechende Brandschutzsektion A bis D entsprechend einer Brandschutzwand zu erreichen.
Die Verteilung und die Anzahl der Löschmittelauswurfeinrichtungen 8 bemessen sich nach den Abmessungen der zu schützenden Fläche, der vorgegebenen Feuerwiderstandszeit und dem notwendigen Volumen des zu erzeugenden Löschmittelnebels. Für eine Fläche von beispielsweise 100 m2 haben sich insgesamt 4 Löschmittelauswurfeinrichtungen 8 zur Erzeugung einer 1,5 m dicken und homogen Löschmittelwand aus Löschmittelnebel als ausreichend erwiesen. Es können z.B. auch nur zwei oder bis zu sechs Löschmittelauswurfeinrichtungen 8 vorgesehen werden, die in der Lage das Löschmittel in unterschiedliche Richtungen je nach den Erfordernissen auszuwerfen.
Als Löschmittelauswurfeinrichtungen 8 sind Sprühwasserdüsen, Feinsprühdüsen, Vollkegeldüsen mit vorgeschaltetem Filter oder steuerbare Düsen gleichermaßen geeignet.In the Fig. 4a to 4d For example, the distribution of the sleeves 16 at the periphery of the vertical supports 2 is shown. The screwed into the sockets 16 Löschmittelauswurfeinrichtungen 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 columns 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 extinguishing agent ejection devices 8 for producing a 1.5 m thick and homogeneous extinguishing agent wall from extinguishing agent mist have proven sufficient. For example, it is also possible to provide only two or up to six extinguishing agent ejection devices 8, which are able to eject the extinguishing agent in different directions depending on the requirements.
As extinguishing agent ejection devices 8 spray water nozzles, fine spray nozzles, full cone nozzles with upstream filter or controllable nozzles are equally suitable.

Der vertikale Abstand der Löschmittelauswurfeinrichtungen 8 ist zweckmäßig mit den Abmessungen der Regalhöhen des in der Brandschutzsektion A oder B aufgestellten Regallagers abgestimmt.The vertical distance of the extinguishing agent ejection devices 8 is suitably matched with the dimensions of the shelf heights of the erected in the fire protection section A or B shelf storage.

Die Fig. 5a und 5b zeigen Varianten der Verankerung der vertikalen Stütze 2 auf bzw. in der Bodenplatte 17 des Bauwerks 1. Für den Fall, dass die vertikalen Stützen 2 auf der Bodenplatte 17 aufgeständert ist, ist die Stütze 2 durch eine Fußplatte 18 flüssigkeitsdicht abgeschlossen, die mittels Gewindestangen 19 in einem Käfig in der Bodenplatte 17 verankert ist. Die vertikale Stütze 2 besitzt nahe ihrer Fußplatte 18 eine Muffe 20 zur Aufnahme einer nicht weiter dargestellten Entlüftungs-und Entleerungseinrichtung. Wenn die vertikale Stütze 2 direkt in der Bodenplatte 17 verankert ist, muss eine Entleerungseinrichtung 46 mit Drainage vorgesehen werden (siehe Fig. 5b).The Fig. 5a and 5b In the case that the vertical supports 2 is elevated on the bottom plate 17, the support 2 is liquid-tightly closed by a foot plate 18, which by means of threaded rods 19 is anchored in a cage in the bottom plate 17. The vertical support 2 has near its base plate 18 a sleeve 20 for receiving a not shown venting and emptying device. If the vertical support 2 is anchored directly in the bottom plate 17, a draining device 46 with drainage must be provided (see Fig. 5b ).

An jede Steuereinheit 7.1...7.n kann ein Detektionsmittel 9, beispielsweise ein hydrothermischer Schlauch mit Gewebearmierung, angeschlossen sein, welcher in den durch die in regelmäßigen Abständen voneinander entfernten Stützen 2 aufgespannten vertikalen Ebenen E1...En zickzackförmig verlegt ist. Der Schlauch wird beispielsweise unter einem Steuerdruck von 0,5 bis 20, vorzugsweise 3,0 bis 4,0 bar gehalten, der durch ein Fremdmedium wie ein Gas, vorzugsweise Druckluft, oder eine Flüssigkeit, vorzugsweise Wasser, erzeugt wird.
Es ist aber auch möglich, anstelle des hydrothermischen Schlauches Wärmelinienmelder oder beispielsweise direkt die Leitung 3 der Stützen 2 überwachende Druckwächter 47 einzusetzen. Die Druckwächter 47 sind dann mit der Logikmatrix 10 verbunden, die die entsprechenden Steuereinheiten 7.1...7.n aktiviert (siehe Fig. 3).
Die Fig. 6 zeigt die Verlegung des hydrothermischen Schlauches in diesen die Brandschutzsektionen umspannenden vertikalen Ebenen El...E.n.To each control unit 7.1 ... 7.n may be a detection means 9, for example, a hydrothermal hose with fabric reinforcement, connected, which is laid in the plane defined by the regularly spaced apart supports 2 vertical planes E1 ... En zigzag. The hose is maintained, for example, under a control pressure of 0.5 to 20, preferably 3.0 to 4.0, bar, which is replaced by a foreign medium such as a gas, preferably compressed air, or a liquid, preferably water, is generated.
But it is also possible, instead of the hydrothermal hose heat detectors or, for example, directly use the line 3 of the supports 2 monitoring pressure switch 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 ).
The Fig. 6 shows the laying of the hydrothermal hose in these vertical sections El ... En

Der hydrothermische Schlauch arbeitet als linienförmiger Thermomelder, der mit einem Steuerdruck von 0,5 bis 20 bar, hier 4 bar, beaufschlagt wird. Das Steuermedium kann gasförmig, vorzugsweise Druckluft, oder auch flüssig, vorzugsweise Wasser sein.The hydrothermal hose operates as a linear thermo-detector, which is supplied with 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.

Sobald in einer Ebene E.1...E.n eine Temperaturerhöhung durch thermische Belastung infolge Flammeneinwirkung stattfindet, führt das zum Druckanstieg des Steuermediums im Schlauch, wodurch ein Platzen des Schlauches und somit ein Druckabfall des Steuermediums verursacht wird.
Dieser Druckabfall wirkt auf die betroffene Steuereinheit 7.1...7.n, die die Öffnung der Löschmittelzufuhr auslöst und den Zutritt des unter Druck bis zu 16 bar stehenden Löschmittels in die vertikalen Stützen 2 zu den entsprechenden Löschmittelauswurfeinrichtungen 8 freigibt.As soon as a temperature increase due to thermal load due to the action of flame takes place in a plane E.1... En, this leads to an increase in pressure 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 acts on the affected control unit 7.1 ... 7.n, which triggers the opening of the extinguishing agent supply and the access of the pressurized up to 16 bar extinguishing agent releases into the vertical supports 2 to the corresponding extinguishing agent ejection devices 8.

Die Steuereinheit 7.1...7.n ist weiterhin mit der Logikmatrix 10 der Brandmeldezentrale verbunden und signalisiert die Auslösung der Löschmittelauswurfeinrichtungen 8 zur Erzeugung der Wasserwand beispielsweise in der Ebene E1. Die Logikmatrix 10 ermittelt die zur entsprechenden Brandschutzsektion A gehörenden weiteren Ebenen E.n und aktiviert die zu diesen Ebenen gehörenden Steuereinheiten 7.n, die ihrerseits die Öffnung der Löschmittelzufuhr in die betroffenen Ebenen E.n veranlassen. Die entsprechende Brandschutzsektion ist somit abgeschottet, so dass das Feuer nicht in die angrenzenden Sektionen des Bauwerks 1 übergreifen kann.The control unit 7.1 ... 7.n is further connected to the logic array 10 of the fire panel and signals the release of the extinguishing agent ejection devices 8 for generating the water wall, for example in the plane E1. The logic matrix 10 determines the further levels En belonging to 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 En. The corresponding fire protection section is thus sealed off, so that the fire can not spread over the adjacent sections of the structure 1.

Der Brandwiderstand der einzelnen Sektionen kann weiter dadurch erhöht werden, wenn innerhalb der Brandschutzsektionen mindestens ein weiteres mit der Logikmatrix 10 verbundenes Detektionsmittel wie beispielsweise ein Rauchmelder vorgesehen ist. Sobald dies eine Brandgefährdung detektiert, steuert die Logikmatrix 10 die zum Brandherd gehörenden Steuereinheiten 7.n an, die die Löschmittelzufuhr zur Erzeugung der vertikalen und/oder horizontalen Löschmittelwände in den den Brandherd umgebenden Sprühebenen zwischen den vertikalen Stützen 2 auslösen. Zweckmäßigerweise kann das mindestens eine weitere Detektionsmittel über Kopf der baulichen Anlage, beispielsweise des Blocklagers, im Dachbereich des Bauwerks 1 befestigt werden.
Natürlich sind neben dem Rauchmelder auch andere Detektionsmittel wie mechanische, hydraulische, thermische, optische Systeme, beispielsweise Sprinklersysteme geeignet.The fire resistance of the individual sections can be further increased if within the fire protection sections at least one further connected to the logic matrix 10 detection means such as a smoke detector is provided. Once this detects a fire hazard, controls the logic matrix 10 belonging to the fire control units 7.n, which trigger the extinguishing agent supply for generating the vertical and / or horizontal extinguishing agent walls in the fire surrounding the spray levels between the vertical supports 2. The at least one further detection means can expediently be fastened in the roof area of the building 1 above the head of the building, for example the block storage.
Of course, other detection means such as mechanical, hydraulic, thermal, optical systems, such as sprinkler systems are suitable in addition to the smoke detector.

Es gehört aber auch zu der Erfindung, wenn das gesamte entlang der Ebenen El...E.n durch Löschmittelwände abgeschottete Blocklager zusätzlich von einer separaten Löschanlage überwacht wird, die an das Rohrsystem 5 angeschlossen ist. Der Aufbau dieser Löschanlage kann beispielsweise derjenigen nach der DE 10 2006 024 088 B3 entsprechen oder aber auch eine handelsübliche Sprinkleranlage sein.But it also belongs to the invention, if the entire along the planes El ... En sealed by extinguishing agent walls block storage in addition of a separate Extinguishing system is monitored, which is connected to the pipe system 5. The structure of this extinguishing system, for example, those of the DE 10 2006 024 088 B3 or be a commercial sprinkler system.

Die Fig. 7 und 8 zeigen den Aufbau der Steuereinheit 7.1 bis 7.n als Trockenvariante. Die Steuereinheit 7.1...7.n besteht im Wesentlichen aus einem mit einer Ein- und Ausgangsleitung 21 bzw. 22 versehenen Membranventil 23 und einem Pilotventil 24. Das Membranventil 23 besitzt eine Membrankammer 25, in der eine Membran 26 zwischen dem Gehäuse 27 des Membranventils 23 und einem die Membrankammer 25 abschließenden Deckel 28 festgelegt ist. Im geschlossenen Zustand liegt die Membran 26 satt auf dem Ventilsitz 29 des Membranventils 23 auf und sperrt den Löschmittelzutritt in die Abströmkammer 30 des Membranventils 23.The Fig. 7 and 8th 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, a 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 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 Löschmittelzutritt in the outflow chamber 30 of the diaphragm valve 23rd

Der Deckel 28 trägt einen Anschluss 31 für einen Druckluftschlauch 32, der mit einer nicht dargestellten Druckluftquelle verbunden ist, sowie das Pilotventil 24. Die Druckluftquelle drückt die Membran 26 auf ihren Ventilsitz 29 und beaufschlagt den an das Pilotventil 24 angeschlossenen, endseitig durch ein Endstück 33 geschlossenen hydrothermischen Schlauch. Druckluftschlauch und hydrothermischer Schlauch sind durch ein Rückschlagventil 34 voreinander gesichert. Der Schlauch kann durch einen Kugelhahn 35 gegenüber dem Pilotventil 24 abgesperrt werden. Ebenso ist es mit einem Kugelhahn 36 möglich, die Löschmittelzufuhr zum Membranventil 23 abzusperren.The cover 28 carries a connection 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 presses the diaphragm 26 on its valve seat 29 and acts on the connected to the pilot valve 24, end by an end 33rd 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.

Sobald der Druckabfall im Schlauch eingetreten ist, wird die Membran 26 entlastet und löst sich infolge des anstehenden Löschmitteldruckes von ihrem Ventilsitz 29. Durch die in die Membran 26 eingearbeitete Düse 37 und Fluidkanäle 38 zwischen Pilotventil 24 und Abströmkammer 30 entweicht die noch in der Membrankammer 25 und im Pilotventil 24 befindliche Luft, so dass ein schnelles Ansprechen des Membranventils 23 gewährleistet ist.As soon as the pressure drop in the tube has occurred, the membrane 26 is relieved and released from its valve seat 29 due to the pending Löschmitteldruckes from the valve seat 29 through the membrane 26 incorporated in the nozzle 37 and fluid channels 38 between pilot valve 24 and outflow chamber 30 escapes in the membrane chamber 25th and in the pilot valve 24 located air, so that a rapid response of the diaphragm valve 23 is ensured.

Das Löschmittel gelangt über die Membrankammer 25 in die Abströmkammer 30 und strömt durch die vertikalen Stützen 2 den Löschmittelauswurfeinrichtungen 8 zu, aus denen das Löschmittel vernebelt in die Ebenen E1...En zur Ausbildung der Löschmittelwand austreten kann.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 atomized in the planes E1 ... En to emerge to form the extinguishing agent wall.

Im Pilotventil 24 oder Anschluss 31 ist ein Drucksensor 39 angebracht, der den Druckabfall detektiert und über eine Verbindungsleitung 40 einem Wandler 41 zuführt, der mit dem Hauptwasserventil der Löschmittelventilstation 4 über eine Regeleinheit in Verbindung steht. Dieselbe öffnet bei Anliegen des Signals das Hauptwasserventil.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 to a converter 41 which is in communication with the main water valve of the extinguishing valve body 4 via a control unit. It opens the main water valve when the signal is present.

Anstelle des Membranventils 23 kann auch ein Magnetventil 42 (siehe Fig. 9) in der Steuereinheit 7.1...7.n zum Einsatz kommen. Die Ansteuerung des Ventils wird in diesem Fall durch einen Druckabfall detektierenden Sensor 39 oder auch durch den Druckwächter 47 initiiert, der den Auslösemechanismus 43 in der Auslösekammer 44 des Magnetventils 42 veranlasst, den Ventilsitz zu öffnen und das anstehende Löschmittel freizugeben.Instead of the diaphragm valve 23 may also be a solenoid valve 42 (see Fig. 9 ) are used in the control unit 7.1 ... 7.n. The control of the valve is initiated in this case by a pressure drop detecting sensor 39 or by the pressure switch 47, which causes the trigger mechanism 43 in the trigger chamber 44 of the solenoid valve 42 to open the valve seat and release the pending extinguishing agent.

Die Fig. 10 zeigt die Steuereinheit 7.1...7.n als Nass-Variante. Für diesen Fall ist kein Sensor 39 zum Erfassen des Druckabfalls und Ansteuern des Hauptwasserventils erforderlich. Das Löschmittel steht ohne zusätzliche Absperrung bis in die Membrankammer 25 an und drückt die Membran dichtend auf den Ventilsitz 29. Der weitere Aufbau entspricht der Steuereinheit 7.1. gemäß Fig. 7.The 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 ,

Die Fig. 11 verdeutlicht den Ablauf des erfindungsgemäßen Verfahrens. Das Bauwerk 1 ist entsprechend den vorliegenden Gegebenheiten in mehrere Brandschutzsektionen A bis D untergliedert. Im Beispiel gibt es eine Sektion A für ein Blocklager, eine Sektion B für ein kurvengängiges Mehrplatzsystem, eine Sektion C für die die Sektionen A und B verbindende Fahrbahn zum Transport von Einlagerungsgut und eine Sektion D für Tore für die Zu- und Ausfahrt in das und aus dem Bauwerk 1.
Die Sektionen A bis D sind jeweils von vertikalen Sprühebenen E1....E.n umgeben, die zwischen den vertikalen Stützen 2 des Bauwerks 1 aufgespannt werden.
Jede dieser Sprühebenen E.1...E.n ist von Detektionsmitteln 9 wie einem Wärmelinienmelder durchzogen und wird auf Temperatur- und Druckänderung überwacht und kontrolliert, so dass jede Sektion A bis D für sich allein separiert ist und gewissermaßen von einer virtuellen Brandschutzwand in Form einer Löschmittelwand aus Sprühnebel einschließbar ist.
Jeder Sprühebene ist mindestens eine Steuereinheit 7.1...7.n zugeordnet, die mit der Logikmatrix 10 der Brandmeldezentrale verbunden ist. Wird durch das Detektionsmittel 9 in einer Sprühebene E.1...E.n ein Druckabfall infolge eines Feuers in einer der Sektionen A bis D detektiert, leitet der Drucksensor 39 diese Information nach Wandlung in ein digitales Signal an die Logikmatrix 10 weiter. Dieselbe verarbeitet das Signal, in dem die zur betroffenen Sektion gehörigen Ebenen E.1...E.n und Stützen 2 ermittelt werden. Die Logikmatrix 10 öffnet über eine Regeleinheit das als Magnetventil ausgeführte Hauptventil der Löschmittelventilstation 4 und steuert die betroffenen Steuereinheiten 7.1...7.n zwecks Erzeugung von vertikalen Löschmittelwänden in den Ebenen E.1...E.n zwischen den Stützen 2 automatisch an. Die brandgefährdete Sektion ist dann allseitig von einer homogenen, dichten Löschmittelwand aus Löschmittelnebel umgeben, die die Funktion einer Brandschutzwand erfüllt.The Fig. 11 illustrates the course 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 E1 .... En, which are spanned between the vertical supports 2 of the structure 1.
Each of these spray levels E.1 ... En is traversed by detection means 9 such as a heat line detector and is monitored for temperature and pressure changes and controlled so that each section A to D is separated on its own and to a certain extent from a virtual fire wall in the form of a Extinguishing agent wall is enclosed by spray.
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 E.1.. Pressure sensor 39 this information after conversion into a digital signal to the logic array 10 on. It processes the signal in which the planes E.1 ... En and columns 2 belonging to the section concerned are determined. The logic matrix 10 opens via a control unit designed as a solenoid valve main valve of the extinguishing valve body 4 and controls the affected control units 7.1 ... 7.n for the purpose of generating vertical extinguishing agent walls in the planes E.1 ... En between the supports 2 automatically. The fire-prone section is then surrounded on all sides by a homogeneous, dense extinguishing agent wall of extinguishing agent mist, which fulfills the function of a fire protection wall.

Sofern der Brand nicht in der Nähe einer der überwachten Ebenen E.1...E.n, sondern im Inneren des beispielsweise in der Sektion A aufgestellten Blocklagers ausgeht, wird das Feuer oder die Brandgefährdung durch mindestens ein weiteres über Kopf des Blocklagers angeordnetes, mit der Logikmatrix 10 verbundenes Detektionsmittel 45, beispielsweise Rauchmelder, detektiert und als Signal an die Logikmatrix 10 übertragen.
Die Logikmatrix 10 veranlasst wie bereits zuvor beschrieben die Öffnung des Hauptventils der Löschmittelventilstation 4 und die Ansteuerung der entsprechenden Steuereinheiten 7.1...7.n zur Erzeugung der Löschmittelwände entlang der betroffenen Sektion.If the fire does not start in the vicinity of one of the supervised levels E.1 ... En, but inside the block warehouse set up, for example, in section A, the fire or the fire hazard will be caused by at least one further head above the block bearing Logic matrix 10 connected detection means 45, such as smoke detectors detected and transmitted as a signal to the logic array 10.
As already described above, 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 extinguishing agent walls along the affected section.

Nachdem die entsprechende Sektion durch Löschmittelwände umschlossen ist, kann natürlich auch innerhalb der Sektion das Feuer oder die Brandgefährdung volumenspezifisch bekämpft werden. Von besonderem Vorteil ist, wenn die volumenspezifische Bekämpfung des Feuers nach dem Verfahren der DE 10 2006 024 688 B3 durchgeführt wird.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. Of particular advantage is, if the volume-specific fight of the fire after the procedure of the DE 10 2006 024 688 B3 is carried out.

Die Logikmatrix 10 kann aber auch durch einen Wärmelinienmelder und/oder automatische Melder ausgelöst werden. Sie ist ebenso von Hand aktivierbar und durch ein Reset rückstellbar.
Als Löschmittel sind neben Wasser auch andere Löschmittel wie Inertgase, chemische Gase, Pulver oder Schäume einsetzbar. Es versteht sich, dass die erfindungsgemäße Vorrichtung zur Durchführung des Verfahrens dann an das entsprechende Löschmittel anzupassen ist.The logic matrix 10 can also be triggered by a heat line detector and / or automatic detector. It can also be activated manually and reset by a reset.
Apart from 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.

Die erfindungsgemäße Lösung führt zu dem außerordentlichen Vorteil, dass das Bauwerk 1 durch die Vielzahl der vertikalen Stützen 2 in Leichtbauweise errichtet werden kann, so dass erhebliche Mengen an Baustoffen eingespart und zugleich auch die Sicherheit und der Brandwiderstand des Bauwerks maßgeblich erhöht werden.
Außerdem ermöglicht es die erfindungsgemäße Lösung, klassische Brandbekämpfungsmethoden zu involvieren, in dem die vertikalen löschmittelführenden Stützen 2, Wasserentnahmeeinrichtungen, wie Armaturen oder Hydranten besitzen, an die entsprechende Feuerbekämpfungsvorrichtungen problemlos anschließbar sind.The solution according to the invention leads to the extraordinary advantage that the structure 1 can be constructed by the plurality 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.

Damit der Korrosion und der Alterung in der erfindungsgemäßen Vorrichtung vorgebeugt werden kann, ist des Weiteren vorgesehen, dass dem Löschmittel entsprechende geeignete Mittel zur Verringerung der Korrosion beigemischt werden.
