Sprinkler system covering is within the scope of the invention z. B. to understand a sprinkler-compatible false ceiling, d. H. a Suspended ceiling, which by its function for covering sprinkler systems serves, these suspended ceilings horizontally below sprinkler systems be attached, which are in or on the ceiling of a room, they are also to understand fabrics that are attached to walls of rooms, in such a case the coverings are arranged vertically and Cover sprinkler systems that move sideways in rooms, i.e. H. in or on the walls are attached.
Textile Unterhängdecken, auch Deckenbespannungen für Sprinkleranlagen genannt, sind bereits bekannt. Für Wände oder Decken von Räumen werden vielfach textile Flächengebilde eingesetzt, die dazu dienen, die häufig sehr nüchtern und technisch ausschauende Sprinkleranlagen abzudecken, so daß sie den Blicken des Betrachters entzogen sind. Abgesehen davon, daß sie die Sprinkleranlage den Blicken des Betrachters entziehen sollen, ist auch gewünscht, daß sie den Wänden und Räumen einen ästhetisches Bild verleihen; darüber hinaus sollen derartige Decken natürlich auch in der Lage sein, im Falle eines Brandes das Ingangsetzen der Sprinkleranlage schnellstens zu ermöglichen und Wasser so schnell wie möglich zur Brandstelle durchzulassen.Textile suspended ceilings, including ceiling coverings for sprinkler systems are already known. For walls or ceilings of rooms often used textile fabrics that serve the very often sober and technically looking sprinkler systems to cover them are out of sight of the beholder. Aside from being the Sprinkler system should be hidden from viewers' eyes is also desirable that they give the walls and rooms an aesthetic picture; about that In addition, such blankets should of course also be able to, in the event of a Fire to enable the sprinkler system to be started as quickly as possible and let water through to the fire site as quickly as possible.
So wird in der DE 198 59 550 A1 ein flexibles Flächengebilde aus sich kreuzenden fadenartigen Gebilden für die Bespannung von Unterdecken, die über eine Sprinkleranlage angeordnet ist, beschrieben, bei dem die fadenartigen Gebilde als Spannfäden ausgebildet sind.

Es ist auch möglich, den Kunststoff in fester Form, z. B. in Form von Pulver, Granulaten usw. aufzubringen und durch eine Wärmebehandlung aufzuschmelzen, so daß er sich entsprechend im Gewebe verteilt.It is also possible to use the plastic in solid form, e.g. B. in the form of powder, To apply granules etc. and to melt them by means of a heat treatment, so that it is distributed accordingly in the tissue.
Eine weitere sehr vorteilhafte Möglichkeit besteht darin, daß man das Gewebe aus Fäden oder Garnen aufbaut, bei denen die Fasern bzw. Fäden bereits mit dem Kunststoffmaterial umhüllt sind.Another very advantageous possibility is that the fabric is made of Builds threads or yarns in which the fibers or threads already with the Plastic material are encased.
Dazu gehören sog. Bikomponenten- oder Mehrkomponentenfasern des Kernmanteltyps, wobei der Kern aus Polyester oder Glasfaser besteht und der Mantel aus dem Kunststoff.These include so-called bicomponent or multicomponent fibers of Kernmanteltyps, where the core is made of polyester or glass fiber and the Sheath made of plastic.
Bei Glasfasern kann der Kunststoff durch Behandlung der Glasfasern oder Glasfilamente mit einer Kunststoffschmelze oder einer Kunststoffdispersion oder Kunststofflösung aufgebracht werden. Bei Polyesterfasern wird der Kunststoff bevorzugt bei der Faserherstellung durch Einsatz einer Mehrkomponentendüse aufgebracht, durch die der Polyester als Kernkomponente und der Kunststoff als Mantelkomponente extrudiert wird.In the case of glass fibers, the plastic can be treated by treating the glass fibers or Glass filaments with a plastic melt or a plastic dispersion or Plastic solution are applied. With polyester fibers, the plastic preferred for fiber production using a multi-component nozzle applied through which the polyester as the core component and the plastic as Sheath component is extruded.
Die flammhemmenden Additive werden bevorzugt zusammen mit dem Kunststoff aufgebracht. Hier ist es vorteilhaft, wenn das oder die flammhemmenden Additive bereits in dem Kunststoff dispergiert oder gelöst sind und entweder mit Beschichtung auf das Gewebe aufgebracht wird oder bei der Herstellung der Bikomponentenfaser- oder filamente als Mantelkomponente eingesetzt wird, die die Additive bereits enthält. The flame retardant additives are preferred together with the plastic applied. Here it is advantageous if the flame retardant or additives are already dispersed or dissolved in the plastic and either with Coating is applied to the fabric or in the manufacture of the Bicomponent fiber or filament is used as a sheath component that which already contains additives.
Die Herstellung der Sprinkleranlagen-Bespannung unter der Verwendung von Polyestermonofilamenten mit einem Polyesterkern kann z. B. auf folgende Weise geschehen: Zunächst werden Kernmantelfilamente auf an sich bekannte Weise hergestellt, dabei wird als Kernmaterial insbesondere ein schmelzverspinnbares Polymer verwendet, das ganz oder teilweise aus Polyester insbesondere Polyethylenterephthalat besteht. Als Mantelkomponente wird bevorzugt Polyvinylchlorid verwendet. Das Polyvinylchlorid enthält ein oder mehrere flammhemmende Additive, welche möglichst homogen in dem Polyvinylchlorid verteilt sind. Als Additive eignen sich übliche flammhemmende Zusätze.The production of the sprinkler system covering using Polyester monofilaments with a polyester core can e.g. B. in the following way happen: First, core sheath filaments are made in a manner known per se is produced, in particular a melt-spinnable core material Polymer used, made entirely or partially of polyester in particular There is polyethylene terephthalate. Preferred is the jacket component Polyvinyl chloride used. The polyvinyl chloride contains one or more flame retardant additives that are as homogeneous as possible in the polyvinyl chloride are distributed. Common flame retardant additives are suitable as additives.
Bevorzugt wird das Gewebe nach der Fertigstellung einer thermischen Behandlung unterzogen, so daß die Filamente an ihren Kreuzungspunkten durch An- oder Aufschmelzen des Mantels mit einander verbunden und fixiert werden. Dadurch wird eine gute Flächenstabilität des Gewebes erhalten.The fabric is preferred after the completion of a thermal Treated so that the filaments pass through at their crossing points Melting or melting of the jacket can be connected to each other and fixed. This gives the fabric good surface stability.
Anschließend wird das Gewebe entsprechend dem Einsatzgebiet für die Sprinkleranlage konfektioniert. Dazu eignen sich u. a. das Hochfrequenzschweißverfahren oder auch das Heizkeilschweißverfahren. Auch durch Nähen können die Gewebe entsprechend konfektioniert werden.Then the fabric is used according to the area of application Sprinkler system assembled. To do this, u. a. the High frequency welding process or the hot wedge welding process. Also the fabrics can be made up accordingly by sewing.
Die Dichte der Schuß- und Kettfäden wird so eingestellt, daß der Flächenbedeckungsgrad 15 bis 80 % beträgt. Unter Flächenbedeckungsgrad im Rahmen der Erfindung ist zu verstehen das Verhältnis Anteil bedeckter Fläche zu Gesamtfläche des Gewebes.The density of the weft and warp threads is adjusted so that the Area coverage is 15 to 80%. Under area coverage in The ratio of covered area to area is to be understood within the scope of the invention Total area of the fabric.
Dies bedeutet beispielsweise, wenn bei einer Gewebefläche von 1 m2 0,2 m2 von den Filamenten des Gewebes eingenommen werden und 0,8 m2 offen sind, dann beträgt der Flächenbedeckungsgrad 20 %. This means, for example, if 0.2 m 2 of the filaments of the fabric are taken up with a fabric area of 1 m 2 and 0.8 m 2 are open, then the area coverage is 20%.
Der Titer der verwendeten Monofile kann in verhältnismäßig weiten Bereichen variiert werden, beispielsweise zwischen 1 000 bis 2 000 dtex. Ein Titer von 1 300 bis 1 500 insbesondere ein 1 400 ist besonders vorteilhaft. Ein sehr vorteilhafte Zusammensetzung ist, Kern mit einem Titer von 550 dtex und Mantel mit einem Titer von 850 dtex.The titer of the monofilaments used can be in relatively wide ranges can be varied, for example between 1,000 and 2,000 dtex. A titer of 1,300 up to 1,500, in particular a 1,400, is particularly advantageous. A very beneficial one Composition is, core with a titer of 550 dtex and coat with a Titer of 850 dtex.
Die Flächenbedeckung kann einerseits durch die Bindungstechnik beeinflußt werden, d. h. durch die Anzahl der Kett- und/oder Schußfäden pro cm oder auch durch den Titer des Garns aus Kern-/Mantel-Filamenten.The area coverage can be influenced on the one hand by the binding technique become, d. H. by the number of warp and / or weft threads per cm or by the titer of the yarn from core / sheath filaments.
Nach dem Konfektionieren oder auch bereits davor können die Gewebe direkt bedruckt, insbesondere digital bedruckt werden, d. h. ohne eine Endveredelung wie z. B. durch Lackierung. Es ist jedoch auch möglich, eine Lackierung des Gewebes mit speziellen Lacken durchzuführen, um die digitale Bedruckbarkeit noch positiv zu beeinflussen oder in bestimmte Richtung zu verändern oder zu erhöhen.After assembly or even before, the fabrics can be used directly printed, in particular digitally printed, d. H. without a finishing such as B. by painting. However, it is also possible to paint the Fabric with special varnishes to ensure digital printability to influence positively or to change or to move in a certain direction increase.
Die Flächenstabilität kann im Rahmen der Erfindung durch die beim Binden und Fixieren der Garne gewählte Temperatur und die Verweilzeiten während der thermischen Behandlung variiert werden.The surface stability can within the scope of the invention by the binding and Fix the selected temperature and the dwell times during the yarn thermal treatment can be varied.
Es ist möglich, die Gewebe zu verwenden, ohne daß sie an den Kreuzungspunkten fixiert sind. Es ist aber auch möglich, die Bedingungen so zu wählen, daß lediglich ein leichtes Anschmelzen stattfindet, ferner kann man durch entsprechende Temperaturverweilzeiten die Verschmelzung auch so weit treiben, daß eine quasi vollständige Verschmelzung an den Kreuzungspunkten stattfindet.It is possible to use the tissues without them at the crossing points are fixed. But it is also possible to choose the conditions so that only a slight melting takes place, further you can by appropriate temperature dwell times drive the fusion so far, that a quasi complete fusion takes place at the crossing points.
Die Sprinkleranlagen-Bespannungen gemäß der Erfindung lassen sich sowohl als sog. Unterhängdecken einsetzten, d. h. bei Sprinkleranlagen verwenden, die in oder an der Decke von Räumen oder Hallen usw. angebracht sind. The sprinkler system coverings according to the invention can be used both as use so-called suspended ceilings, d. H. use with sprinkler systems that are in or are attached to the ceiling of rooms or halls, etc.
Dabei werden die Bespannungen horizontal unterhalb der Sprinkleranlage angebracht. Sie können direkt unterhalb der Sprinkleranlage an der Decke befestigt werden. Es ist aber auch möglich, sie in Rahmen einzuspannen und in Form von Rahmen an der Decke zu befestigen.The coverings are horizontal below the sprinkler system appropriate. You can directly below the sprinkler system on the ceiling be attached. But it is also possible to clamp them in frames and in Form of frame to attach to the ceiling.
Die Bespannungen weisen ein ruhiges und geschlossenes Bild auf und lassen nicht erkennen, daß sie eigentlich nur zum Abdecken der Sprinkleranlagen verwendet werden. Sie bieten somit ein textiles oder tapetenartiges Bild. Sie können mit den üblichen lösungsmittelhaltigen Farben gemäß der Digitaldrucktechnik bedruckt werden und bieten somit die Möglichkeit der Decke ein sehr ansprechendes ästhetisches Gepräge zu verleihen.The fabrics have a calm and closed picture and do not leave recognize that it is actually only used to cover the sprinkler systems become. They therefore offer a textile or wallpaper-like image. You can use the customary solvent-based colors printed according to digital printing technology and thus offer the possibility of a very attractive ceiling to give aesthetic character.
In gleicher Weise können die Bespannungen auch vertikal bei Sprinkleranlagen, die in Wänden von Räumen integriert sind, angebracht werden.In the same way, the coverings can also be used vertically in sprinkler systems, which are integrated in the walls of rooms.
Die Bespannungen bieten im Falle eines Brandes der beim Brand entstehenden Wärmestrahlung kein Hindernis, so daß die Sprinkleranlage bei Entstehen eines Brandes unmittelbar in Funktion treten kann. Aufgrund der gewählten Flächenbedeckung bieten die Bespannungen bei Ausstoßen des Wassers durch die Sprinkleranlage auch keinen ernsthaften Widerstand, so daß das Wasser bei Betrieb der Sprinkleranlage sofort ungehindert auf die Brandstelle gespritzt werden kann. Dies gilt sowohl bei horizontaler als auch bei vertikaler Anbringung.In the event of a fire, the coverings offer those created during the fire Heat radiation is not an obstacle, so that the sprinkler system when a Fire can function immediately. Because of the chosen Coverage is provided by the coverings when the water is expelled through the Sprinkler system also has no serious resistance, so the water at Sprinkler system operation immediately sprayed onto the fire site unhindered can be. This applies to both horizontal and vertical installation.
Die erfindungsgemäßen Sprinkleranlagen-Bespannungen können deshalb auch vorteilhaft auch als Deckenabspannmaterial zur Messestandbespannung verwendet werden. Es können dabei Flächen bis zu beispielsweise 30 m2 frei überspannt werden. Durch ein entsprechend starkes Verspannen kann ein störendes Durchhängen vermieden werden. The sprinkler system coverings according to the invention can therefore also advantageously be used as ceiling covering material for covering the exhibition stand. Areas of up to 30 m 2, for example, can be freely spanned. A disturbing sagging can be avoided by appropriately strong tensioning.
Die Konfektionierung ist ohne weiteres mit den üblichen Methoden möglich, z. B. mittels Hochfrequenzschweißverfahren, Heißkeilschweißverfahren oder mittels Nähtechnologien. Dabei können in den Randbereichen Ösen mit einkonfektioniert werden oder Rahmenvorrichtungen konfektioniert werden, so daß die textile Bespannung verspannt werden kann. Mit Ösen wird direkt vor Ort verspannt, Rahmenkonstruktionen werden vorher verspannt und dann als gesamter Rahmen angebracht.The assembly is easily possible with the usual methods, e.g. B. by means of high frequency welding processes, hot wedge welding processes or by means of Sewing technologies. Eyelets can be assembled in the edge areas be or frame devices are assembled so that the textile Can be tensioned. With eyelets, tensioning is carried out on site, Frame structures are braced beforehand and then as an entire frame appropriate.
Durch die Verwendung von brandhemmenden Additiven in dem Mantel entsprechen die Bespannungen gemäß der Erfindung auch der im Innenbereich erforderlichen Brandklasse nach DIN 4102 B1 und/oder nach der französischen Norm M1 oder M2.Through the use of fire-retardant additives in the jacket, the coverings according to the invention also correspond to the fire class required in the interior according to DIN 4102 B1 and / or according to the French standard M 1 or M 2 .
Es war besonders überraschend, daß gemäß der Erfindung Sprinkleranlagen-Bespannungen zur Verfügung gestellt werden können, die hervorragend arbeiten, die den erforderlichen Brandvorschriften entsprechen und die darüber hinaus ein angenehmes ästhetisches Bild dem Beobachter vermitteln.It was particularly surprising that sprinkler system coverings according to the invention can be made available that work excellently, which correspond to the required fire regulations and which also convey a pleasant aesthetic image to the observer.
Besonders vorteilhaft ist auch die hohe Luftdurchlässigkeit der Sprinkleranlagen-Bespannung gemäß der Erfindung. Dies hat u. a. den Vorteil, daß für eine gute Luftzirkulation Sorge getragen wird und verbrauchte und überhitzte Luft in Entlüftungsanlagen, die direkt an der Decke angebracht sind, abgeführt werden kann. Ein Ansammeln von überhitzter Luft, die dann ohne daß ein Brand entstanden ist, die Sprinkleranlage auslösen könnte, wird dadurch vermieden. Rauchgase und heiße Luft, die im Brandfalle entstehen, können unverzögert den Sprinkleralarm auslösen.The high air permeability of the sprinkler system covering is also particularly advantageous according to the invention. This has u. a. the advantage that for good Air circulation is taken care of and used and overheated air in Ventilation systems that are attached directly to the ceiling are discharged can. An accumulation of superheated air, which is then without a fire is created, which could trigger the sprinkler system, is avoided. Smoke gases and hot air that arise in the event of a fire can Trigger sprinkler alarm.
Die Erfindung wird durch folgendes Beispiel näher erläutert: The invention is illustrated by the following example:
Aus einem Kernmantelfilament mit einem Titer von 1400 dtex, das aufgebaut ist aus einem Kernmaterial 550 dtex Polyester hochfest und einem Mantelmaterial 850 dtex Polyvinylchlorid schwerbrennbar, wird ein Gewebe in Panama 22 Bindung hergestellt. Einstellung Kette: 6 Fäden pro cm, Schußeinstellung: ebenfalls 6 Fäden pro cm. Das erhaltene Gewebe hat ein Flächengewicht von ca. 165 g/m2 und weist einen Flächenbedeckungsgrad von ca. 48 % auf. Das Gewebe wird mit einem steigenden Temperaturprofil von 150° C aufwärts bis 170° C während einer Verweilzeit von ca. 3 Min. thermo fixiert. Anschließend wird das Gewebe zu einer Sprinkleranlagenbespannung konfektioniert.A Panama 22 weave is made from a core sheath filament with a titer of 1400 dtex, which is made up of a core material 550 dtex polyester high-strength and a sheath material 850 dtex polyvinyl chloride. Chain setting: 6 threads per cm, weft setting: also 6 threads per cm. The fabric obtained has a weight per unit area of approximately 165 g / m 2 and a degree of surface coverage of approximately 48%. The tissue is thermally fixed with an increasing temperature profile from 150 ° C up to 170 ° C for a dwell time of approx. 3 min. The fabric is then assembled into a sprinkler system covering.
