[0001] The invention relates to a fire limitation system for limiting the spread of a fire in a building, comprising at least one separation device which is designed to separate the interior of the building into at least two sub-areas in at least one operating state in order to at least delay the spread of a fire between the sub-areas.
[0002] A fire containment system for limiting the spread of a fire in a building has already been proposed, comprising at least one separating device designed to divide the interior of the building into at least two sub-areas in at least one operating state in order to at least delay the spread of a fire between the sub-areas.
[0003] In particular, separation devices are known in the prior art that are designed as fire-resistant masonry or other physical structural fire protection structures. These include, in particular, solid firewalls, fire-resistant partition walls, fire doors, or comparable permanently space-dividing components that are firmly anchored in the building plan and permanently determine the use and spatial division of the interior.
[0004] The object of the invention is, in particular, to provide a generic device with improved properties with regard to simplicity, especially ease of retrofitting, and cost-efficiency. This object is achieved according to the invention by the features of claim 1, while advantageous embodiments and further developments of the invention can be found in the dependent claims. Advantages of the invention
[0005] The invention relates to a fire limitation system for limiting the spread of a fire in a building, with at least one separating device which is designed to separate the interior of the building into at least two sub-areas in at least one operating state in order to at least delay the spread of a fire between the sub-areas.
[0006] It is proposed that the separation device comprise at least one hose with a longitudinally perforated structure, the hose being designed to be attached to a building support and, upon application of extinguishing water, to form a water curtain to separate the building sections. Advantageously, a system can be provided to prevent or at least delay the spread of a fire within a building. Advantageously, a space-saving alternative to conventional firewalls can be provided. Particularly advantageously, a particularly cost-effective fire protection system can be provided. Particularly advantageously, the water curtain can achieve a particularly efficient separation of building sections. Advantageously, a fire containment system that can be integrated particularly easily into an existing building can be provided.
[0007] The fire containment system is designed to provide a fire-resistant separation of sections of the building's interior in the event of a fire. During normal operation, the fire containment system does not constitute a separation of the building's interior, and the use of the interior is not hindered by the fire containment system during normal operation. The sections of the building can be designed as functionally separate areas. Furthermore, the sections can be defined in fixed volume units, for example, with a volume of approximately 10,000 cubic meters each. The sections can also be designed to comply with the legal requirements for fire protection subdivisions. The building can be used for industrial purposes, particularly agricultural purposes.For example, the building could be designed as an agricultural storage building. It could also be intended for wood processing or storage. Furthermore, it could be designed as a workshop, machine hall, production hall, warehouse or logistics hall, freight forwarding hall, garage, or parking structure. Additionally, it could be designed as an animal housing building, in particular as a cattle, pig, poultry, horse, or dairy barn, or as a riding arena. Moreover, the building could be any other commercially or industrially used building with increased fire safety requirements. In an inactive operating state, the separating device is designed as a passive component that does not provide any separation.In an active operating state, particularly in the event of a fire or test, the separation device is configured to provide separation between at least two sections of the building. The separation device is designed to provide functional and spatial separation, specifically fire-limiting separation, of building sections by means of a water curtain. The water curtain is configured to provide fire-limiting separation between at least two interior building areas, extending at least substantially from the support beam located in the roof area of the building to a floor within the building. A "fire-limiting separation" is understood to mean, in particular, that the spread of fire, heat radiation, and smoke gases is at least partially, preferably at least substantially, slowed down and, most preferably, prevented.
[0008] The disconnect device includes a hose designed to be filled with extinguishing water in at least one operating state, particularly in the event of a fire or during testing. In its unfilled state, the hose is loosely arranged as an elastic hose on the building support. The hose is preferably designed as a pressure hose, configured to fully expand only when filled with extinguishing water. The hose can be filled with compressed air for testing purposes. For example, it is conceivable that the hose could be pressurized with compressed air for regular testing and / or cleaning or initial commissioning. It is conceivable that the hose could have a compressed air connection for this purpose.
[0009] The hose has two ends, each equipped with a coupling element. Each coupling element is specifically designed as a fluidically conductive coupling element. One of the coupling elements may have a closure or be designed as a fluid-tight closure. The coupling elements are configured to be optionally coupled to another hose or to a connecting unit, or to be sealed fluid-tight with the closure. In particular, the coupling elements are designed such that different connecting elements, for example, fire service couplings, especially Storz couplings, can be detachably connected to the coupling elements.
[0010] The hose has a multitude of holes along its length. The holes are preferably arranged in a repeating pattern. The holes are preferably spaced equally apart. The holes are preferably arranged in a straight line. The holes are preferably spaced a maximum of 5 m apart, in particular a maximum of 2 m, and preferably less than 1 m apart. It is also conceivable that the holes are spaced 80 cm, 50 cm, or 40 cm apart. The water jets emerging from the holes in the hose are designed to form the water curtain. The water curtain is preferably formed by a multitude of water jets arranged parallel to one another.Alternatively or additionally, the water curtain can be formed by an arrangement of water jets that overlaps at least in sections, so that an essentially continuous water surface is formed.
[0011] The term "longitudinal extension direction" of an object is understood to mean, in particular, a direction that runs parallel to the longest edge of the smallest geometric cuboid that just completely encloses the object.
[0012] In this context, "removable" should be understood to mean in particular "separable without destruction".
[0013] In this context, "at least substantially" is to be understood in particular as meaning that a deviation from a given value is in particular less than 25%, preferably less than 10% and most preferably less than 5% of the given value.
[0014] The term "configured" should be understood to mean, in particular, "specifically designed and / or equipped". The fact that an object is configured for a specific function should be understood to mean, in particular, that the object fulfills and / or performs this specific function in at least one application and / or operating state.
[0015] Furthermore, it is proposed that the separating device have several retaining elements designed to attach the hose to the support. Advantageously, the multiple retaining elements ensure a reliable attachment of the hose to the support. Advantageously, the multiple retaining elements guarantee a defined position of the hose relative to the support. Advantageously, the multiple retaining elements ensure a stable arrangement of the hose, even during a fire. Advantageously, the multiple retaining elements allow the hose attachment to be adapted to different support areas. Advantageously, the multiple retaining elements distribute the holding forces along the hose. The retaining elements are designed to receive the hose and connect it to the support.The retaining elements can be designed as clamps or clamp holders that hold the hose to the support by friction. Alternatively, the retaining elements can be designed as clips or snap-in clips that hold the hose securely in a receiving contour. It is also conceivable that the retaining elements are designed as hooks or eyelets, with the hose being held to the hooks or eyelets by separate straps, in particular steel or wire straps. It is also conceivable that the retaining elements are designed as rails, profile rails, or mounting rails in or on which the hose is guided indirectly via further retaining means. Preferably, the retaining elements are designed as screw holders or holders equipped with screw bolts, which are attached to the support via screw connections. The retaining elements are preferably designed as hose clamps.The hose clamps are designed to be attached to the support, particularly a roof rack. The hose clamps are also designed to hold the hose in an empty, inactive state on the support. The retaining elements may be designed to prevent the hose from twisting. In particular, the retaining elements may be designed to at least assist in the correct positioning of the hose. Specifically, the retaining elements are designed such that the hose can only be mounted correctly. "Correct mounting" of the hose means, in particular, that the hose has no twists or kinks that could prevent or impede the supply of extinguishing water.Furthermore, "correct positioning" of the hose shall be understood in particular to mean that the hose is positioned such that the holes in the hose are arranged at least substantially, preferably completely, pointing downwards towards a building floor or an intermediate floor.
[0016] Furthermore, it is proposed that the hose has a nozzle element at each hole, each enabling the exit of a water jet. Advantageously, a particularly reliable and durable separation device can be provided. A water jet arrangement that can be individually adjusted during assembly is particularly advantageous. The nozzle elements are preferably made of metal and / or plastic. The nozzle elements are preferably arranged essentially congruently with the holes on the hose. The nozzle elements can be manually adjustable. The nozzle elements are designed such that different extinguishing water exit angles can be set, at least during one assembly of the hose, thereby enabling the creation of different water jet arrangements.In this way, different water jet configurations can be set depending on the building's height or width. The nozzle elements are further designed to ensure that at least a substantially similar amount of water, and in particular a substantially uniform water jet, emerges from each opening in the hose. The nozzle elements are preferably arranged on the hose such that the water jets exit the hose at an angle of 10 to 120 degrees, preferably 90 degrees, to the hose's longitudinal direction. The nozzle elements can have a locking or rotating mechanism, allowing multiple water jet angles to be set from a single nozzle element without tools.Furthermore, the nozzle elements can be designed such that different extinguishing water discharge angles can be set for different groups of nozzle elements along the longitudinal extent of the hose. For example, in an agricultural building, a first water jet component could preferably be directed towards an animal or feed area, and a second water jet component could preferably be directed towards a roof or wall area.
[0017] Furthermore, it is proposed that the hose, in at least one operating state, particularly when extinguishing water is being supplied, be configured to form a water curtain between the support structure, especially a roof truss, and the floor of the building. Advantageously, this provides a particularly efficient and safe division of the building. Particularly advantageously, the spread of smoke gases can be at least partially, and preferably at least substantially, delayed. Preferably, the separating device, especially the hose, extends substantially over the entire longitudinal extent of the support structure, particularly a support structure designed as a roof truss, purlin, girder, beam, or frame element, so that the resulting water curtain provides a substantially continuous barrier against flames and smoke gases along the support structure.It is intended that the hose is arranged along the longitudinal extent of a beam, the beam forming a boundary between two sections of the building, so that the water curtain acts as a fire-limiting barrier between these sections. Alternatively or additionally, the hose may be arranged not directly on a roof beam, but on another structural element of the building, in particular on a column, a wall section, a girder, a frame member, a separate support system, or a temporary support structure provided for this purpose, wherein the respective structural element defines a boundary between two sections of the building and the water curtain provides a fire-limiting barrier along this element. Alternatively, it is conceivable that the barrier device could be arranged transversely to a beam.Furthermore, it is conceivable that the separating device is arranged along an outer edge of a building, in particular along a horizontally running eaves edge or along a gable edge of a roof.
[0018] Furthermore, it is proposed that the fire containment system include at least one rigid deflection element designed to connect two hoses at an angle in a fluidically conductive manner. Advantageously, this allows for a fire containment system with high flexibility regarding different building configurations. Particularly advantageous is the ability to connect hoses without kinking. The deflection element is specifically designed to connect at least two hoses at an angle. The deflection element is specifically designed to prevent either hose from kinking. Furthermore, the deflection element is designed to prevent the connected hoses from twisting.Preferably, a deflection element is arranged at one end of a hose and a connecting unit at the other end, wherein the deflection element and the connecting unit are rigidly connected to the support, thus providing a twist-proof mechanism for the hose. In particular, deflection elements with different angles are conceivable. The deflection elements can be designed as rigid pipe bends, providing, for example, deflection angles of 45 degrees, 60 degrees, 90 degrees, or 120 degrees. Alternatively or additionally, deflection elements with adjustable angles can be provided. It is conceivable that at least one deflection element is designed as an articulated element with at least one pivotable section, thus providing an adjustable deflection angle.The deflector may be designed to have more than two connections, thus providing not only deflection but also the distribution of a fire-fighting water flow to multiple hoses. The deflector may have an integrated coupling system, in particular a standardized fire service coupling, allowing direct connection of a supply hose without an additional intermediate piece. It may be designed to have at least one deflector with a rotatable coupling, allowing the inlet or outlet hose to rotate relative to the deflector while maintaining the deflection angle of the deflector itself. It is conceivable that at least one deflector may be made of a corrosion-resistant material, in particular stainless steel and / or fiber-reinforced plastic, to enable its use in agricultural buildings with increased humidity and ammonia levels.
[0019] Furthermore, it is proposed that the fire containment system include a connection unit located outside the building, in particular a fire service water supply unit, preferably a Storz coupling, configured to provide a connection for a fire service water tender. Advantageously, the fire containment system can provide a system for attacking fires inside a building that can be operated from outside the building. Advantageously, it can provide a particularly quick and easy means of fire-limiting the separation of sections within a building. Advantageously, it can provide a particularly simple and reliable means of evacuating livestock, equipment, or people. The connection unit is configured to supply fire-fighting water to the separation device from outside the building.The connection unit is designed such that, in particular, a fire engine or pump truck can be directly connected to it. For this purpose, the connection unit has a connection element that is designed for a fluidically conductive connection with fire service equipment, especially hoses or pumps with a Storz coupling. Furthermore, the connection unit can be designed to supply extinguishing water from a connected water source or, alternatively, to supply extinguishing water from multiple water sources. For example, the connection unit can have two or more connection elements, each designed for connection to different water sources, such as two or more tank trucks. The connection unit is preferably designed to ensure straightforward connection of fire service equipment.Preferably, the connection element(s) is / are designed as a fire service coupling, in particular with a Storz coupling. Preferably, the fire limitation system has at least one further connection unit. Preferably, several connection units are arranged in different areas outside the building to provide a fire water supply to an area of the building farther from a fire. In particular, it can be provided that at least one connection unit is located near an area accessible to fire service vehicles.
[0020] Furthermore, it is proposed that the fire suppression system include a pump unit designed to supply extinguishing water to the separation device, particularly to the hose. Advantageously, a particularly rapid activation of the extinguishing water supply can be provided. Particularly advantageous is the immediate supply of extinguishing water, thereby at least partially bridging the waiting time for the arrival of emergency services. The fire suppression system includes, in particular, an external water reservoir, especially a rainwater cistern, fire water pit, or pond, or a connection to a water supply system. By means of the pump unit, water can be supplied from the water reservoir or the water supply system to the separation device as extinguishing water.It is particularly conceivable that the pump unit has several operating states, with fire-fighting water being supplied to the separation device only in one of these states. It is also conceivable that the pump unit is designed to pump water, liquid manure, or fertilizer in another operating state. For example, the pump unit could be integrated into an agricultural machine, especially a liquid manure tanker. Furthermore, the pump unit could be designed as a stationary pump permanently installed on the building and connected to the water reservoir and the separation device. Alternatively, the pump unit could be designed as a mobile unit mounted on a chassis or trailer and connected to the separation device in case of fire. Finally, the pump unit could be powered by a tractor's power take-off (PTO) shaft.
[0021] Furthermore, it is proposed that the fire containment system include a valve unit designed to regulate the supply of extinguishing water from outside the building. Advantageously, a quick and reliable connection of the isolation device to a water supply system can be provided. Advantageously, features for the rapid and reliable isolation of sections of a building in the event of a fire can be provided. The valve unit can be designed as a throttle valve configured to limit the maximum flow of extinguishing water into the isolation device. It can be provided that several valve units for supplying extinguishing water to the isolation device are arranged, each assigned to a section of the building and, for example, providing a sectional supply of extinguishing water to different sections of the isolation device.Furthermore, the valve unit can be designed to allow for test operation with a reduced extinguishing water flow or a limited supply duration. It is conceivable that the valve unit is designed as a manually operated valve. Preferably, the valve unit is configured to supply extinguishing water from a water supply system, in particular a continuously flowing water supply system, to the separating device. Preferably, the valve unit is positioned such that it can be actuated at a sufficient safety distance from a fire. It is also conceivable that the valve unit is coupled to a fire alarm system. For example, it is conceivable that the valve unit can be actuated automatically by means of a control unit when a fire alarm system, in particular a smoke detector, triggers an alarm.Additionally, the automatic valve unit can be equipped with a manual emergency operation, so that the valve unit can be opened or closed manually even if the automatic control fails.
