Description

Palettencontainer  pallet container
Die Erfindung betrifft einen Palettencontainer zur Lagerung und zum Transport von insbesondere brennbaren oder leicht entzündlichen flüssigen Füllgütern mit einem dünnwandigen starren Innenbehälter aus thermoplastischem Kunststoff zur Aufnahme des flüssigen Füllgutes, mit einem den Kunststoff-Innenbehälter als Stützmantel dicht umschließenden Rohrgitterrahmen aus miteinander verschweißten Rohren und mit einer Bodenpalette, auf welcher der Kunststoffbehälter aufliegt und mit welcher der Rohrgitterrahmen fest verbunden ist, wobei der Kunststoff-Innenbehälter innerhalb des Rohrgitterrahmens von einer Feuerschutz-Isoliermatte umschlossen ist und die The invention relates to a pallet container for storage and transport of particular flammable or flammable liquid products with a thin-walled rigid inner container made of thermoplastic material for holding the liquid filling material, with a plastic inner container as a support jacket tightly enclosing tubular lattice frame of tubes welded together and with a Floor pallet on which the plastic container rests and with which the pipe grid frame is firmly connected, wherein the plastic inner container is enclosed within the pipe grid frame of a fire-resistant insulating mat and the
Bodenpalette als Composite-Palette aus Stahlblech-Rahmen mit Kunststoff-Füßen ausgestaltet ist. Floor pallet is designed as a composite pallet of sheet steel frame with plastic feet.
Stand der Technik : State of the art :
Ein ähnlicher Palettencontainer mit Stahlpalette ist aus der DE 197 47 690 A1 bekannt, der sich durch eine feuerhemmende Bauweise auszeichnen und eine hinreichende Feuerwiderstandsfähigkeit besitzen soll. Dazu ist bei diesem Palettencontainer zwischen Kunststoff-Innenbehälter und Gitterkäfig eine dünnwandige thermische Isolierung angeordnet, die aus Pappe und Aluminiumfolie besteht. Diese plattenförmige Isolierung soll auch zumindest bei Stahlpaletten zwischen Innenbehälter-Unterboden und Paletten- Oberboden eingesetzt sein. Nachteilig bei dieser bekannten Ausführung ist, dass die bodenseitige Entnahmearmatur und der gesamte Innenbehälter-Oberboden mit A similar pallet container with steel pallet is known from DE 197 47 690 A1, which is characterized by a fire-retardant construction and should have a sufficient fire resistance. For this purpose, a thin-walled thermal insulation is arranged in this pallet container between plastic inner container and lattice cage, which consists of cardboard and aluminum foil. This plate-shaped insulation should also be used at least in steel pallets between inner container subfloor and pallet topsoil. A disadvantage of this known design is that the bottom-side removal fitting and the entire inner container topsoil with
Einfüllstutzen und Schraubkappe frei und offen zugänglich bleibt und diese Bauteile somit völlig ungeschützt den Flammen eines angrenzenden Feuers ausgesetzt sind. Dadurch kann dieser Palettencontainer mit unzureichendem Flammenschutz nur sehr kurzzeitig den Einwirkungen eines von außen einwirkenden Feuers widerstehen. The filler neck and screw cap remain open and open and these components are thus exposed to the flames of an adjacent fire completely unprotected. As a result, this pallet container with insufficient flame protection can only very briefly withstand the effects of an externally acting fire.
In der DE 101 61 693 A1 wird ein anderer Palettenbehälter mit Feuerschutz-Ausstattung auf einer Stahlpalette offenbart, bei dem zwischen Innenbehälter und Gitterrahmen ein aus Blechtafeln bestehender Brandschutzmantel und eine zusätzliche Feuer- und Wärmeisolierung angeordnet ist, die auch den Ober- und Unterboden des Kunststoff- Innenbehälters bedeckt. Der Kunststoff-Innenbehälter ist zur Ableitung von elektrischen Ladungen zudem noch von einer gitterartigen Umhüllung aus dünnem Metalldraht umschlossen. Dieser bekannte Palettenbehälter mit verbesserter In DE 101 61 693 A1 another pallet container with fire protection equipment on a steel pallet is disclosed in which between inner container and lattice frame consisting of metal sheets fire protection jacket and an additional fire and heat insulation is arranged, which is also the top and bottom of the plastic - Inner container covered. The plastic inner container is for the derivation of electrical charges also still surrounded by a lattice-like envelope of thin metal wire. This known pallet container with improved
Feuerschutz-Ausstattung soll den Feuerschutzrichtlinien nach der US-Norm NFPA-30 zur Lagerung von brennbaren und leicht entzündlichen Flüssigkeiten, die von den Fire protection equipment shall comply with the fire safety regulations of the US NFPA-30 standard for the storage of flammable and highly flammable liquids used by the
Underwriters Laboratories (UL) überwacht werden, entsprechen und soll die Innenblase bei Feuer mindestens 20 Minuten lang bei Unterstützung durch eine Sprinkleranlage vor Beschädigung bzw. gegen Auslaufen des flüssigen Füllgutes schützen. Underwriters Laboratories (UL) shall comply with and shall protect the inner bladder against damage or leakage of the liquid contents during a fire for at least 20 minutes, assisted by a sprinkler system.
Bei einem aus der EP 1481918 A1 bekannten Palettencontainer mit Holzpalette ist zur Ableitung von elektrischen Ladungen an wenigstens einem Palettenfuß ein Ableitblech angebracht, das eine elektrische Verbindung vom Metallgitterkäfig zum Boden darstellen soll. Eine verbesserte Lösung für die gleiche Problematik wird in der EP 2433880 A1 beschrieben. Dort ist bei einem Palettenbehälter mit Kufen-Palette wenigstens ein In a known from EP 1481918 A1 pallet container with wooden pallet for discharging electrical charges on at least one Palettenfuß a deflector mounted, which is intended to represent an electrical connection from the metal grid cage to the ground. An improved solution to the same problem is described in EP 2433880 A1. There is at least one pallet container with runners palette

Weiterhin ist ein Plastic foot provided with a sheet metal part, which is arranged to dissipate an electrical charge in a recess within the plastic foot and having a stationary contact portion and a stack contact surface. Furthermore, a

Bei dem zuletzt genannten Stand der Technik geht es ausschließlich um die Verhinderung von elektrischen Aufladungen der corresponding plastic container with a metallic sheet metal part within a pallet Eckfußes for dissipation of electrical charges in the floor of the publication JPH11157535 (A) known. In the last-mentioned prior art, it is all about the prevention of electrical charges of

Problematik : Bei einem Einsatz von Composite-Paletten mit Kunststoff-Eckfüßen für UL- IBCs kann es vorkommen, dass im Fall eines länger andauernden Feuers mit starker Hitzeeinwirkung von außen eben diese Kunststoff-Eckfüße zu erweichen beginnen und danach zu brennen anfangen. Dadurch wird die Standfestigkeit von befüllten Problem: When using composite pallets with plastic corner feet for UL IBCs, it can happen that these plastic corner feet begin to soften and then start to burn in the event of a prolonged fire with strong external heat. This will increase the stability of filled
Palettencontainern stark beeinträchtigt und es kann bei übereinandergestapelten Pallet containers severely impaired and it can stacked on top of each other
Palettencontainern sogar zu einem Umstürzen eines solchen Stapels kommen. Diese besondere Problematik tritt bei reinen Stahlpaletten natürlicherweise nicht auf. Pallet containers even come to a toppling of such a stack. This particular problem naturally does not occur with pure steel pallets.
Es ist Aufgabe der vorliegenden Erfindung einen mit Composite-Palette aus Stahlblech- Rahmen und Kunststoff-Füßen ausgestatteten Palettencontainer mit Flammschutz- Ausrüstung derart weiter auszubilden, dass die bestehenden Nachteile des Standes der Technik überwunden werden, und dass durch eine besondere Bauweise desselben eine hinreichende Feuerwiderstandsfähigkeit mit beständiger Standfestigkeit auch bei erhöhter thermischer Belastung, wie z. B. bei direkter Einwirkung von Feuer gegeben ist. It is the object of the present invention to provide a pallet container equipped with a composite pallet made of sheet steel frame and plastic feet with flame retardant Equipment in such a way that the existing disadvantages of the prior art are overcome, and that by a special construction of the same a sufficient fire resistance with stable stability even at elevated thermal stress, such. B. is given in the direct action of fire.
Lösung: Diese Aufgabe wird mit den speziellen Merkmalen des Patentanspruchs 1 gelöst. Die Merkmale in den Unteransprüchen beschreiben weitere vorteilhafte Solution: This object is achieved with the special features of patent claim 1. The features in the subclaims describe further advantageous
Ausgestaltungs-möglichkeiten des erfindungsgenmäßen Palettencontainers. Die vorgeschlagene technische Lehre eröffnet einen Einsatz der Composite-Palette bei einem UL-IBC, wobei insbesondere für befüllte, übereinandergestapelte UL-IBCs die Standfestigkeit (Stapelbelastbarkeit) erhalten bleibt und ein Umstürzen der UL-IBC verhindert wird. Dies wird in effektiver Weise dadurch gelöst, dass jedem Kunststoff- Eckfuß wenigstens ein separates hitzebeständiges Stützelement zugeordnet ist, das derart ausgebildet ist, dass es auch bei hoher thermischer Belastung starke Druckkräfte in Vertikalrichtung überträgt. Dadurch kann ein Kunststoff-Eckfuß als solcher erweichen und sogar verbrennen, ohne dass - im Fall eines Feuers - die Standfestigkeit von befüllten, übereinandergestapelten UL-IBCs in nachteiliger weise beeinträchtigt wird. In vorteilhafter Weise ist das Stützelement von außen nicht sichtbar innerhalb des Design possibilities of erfindungsgenmäßen pallet container. The proposed technical teaching opens up a use of the composite pallet in a UL-IBC, wherein in particular for filled, stacked UL IBCs the stability (stack load capacity) is maintained and overturning of the UL IBC is prevented. This is effectively achieved in that each plastic corner foot is associated with at least one separate heat-resistant support element which is designed such that it transmits strong compressive forces in the vertical direction even under high thermal stress. As a result, a plastic corner foot as such can soften and even burn, without - in the case of a fire - the stability of filled, stacked UL IBCs is adversely affected. Advantageously, the support element is not visible from the outside within the
Kunststoff-Eckfußes der Composite-Palette angeordnet und stützt sich nach oben gegen eine obere, auf dem äußeren Rand der oberen Tragplatte verlaufende Winkelschiene und nach unten gegen das umlaufende Boden-Rohrgestänge ab. Plastic Eckfußes the composite pallet arranged and is supported upwards against an upper, running on the outer edge of the upper support plate angle rail and down against the rotating floor pipe string from.
Für das Stützelement können verschiedene hitzebeständige Materialien in Frage kommen (z. B. Keramikteile, Aluminiumteile oder dergleichen). Vorzugsweise ist das Stützelement jedoch aus einem stabilen länglichen Stahlblechstreifen gefertigt und in einem einfachen Stanz- und Biegeverfahren zu einem hohlen rohrförmigen Various heat-resistant materials may be suitable for the support element (eg ceramic parts, aluminum parts or the like). Preferably, however, the support element is made of a stable elongated sheet steel strip and in a simple punching and bending process to a hollow tubular

Da das Stützelement in der Praxis weniger durch Zugbelastung sondern viel mehr durch starke Druckbelastung beansprucht wird, ist das obere Deckelteil des hohlen Stützelements innerhalb des Kunststoff-Eckfußes nach oben fest mit der auf dem äußeren Rand der oberen Tragplatte verlaufenden Winkelschiene verbunden (z. B. vernietet oder verschraubt) und nach unten mit dem unteren Bodenteil auf dem bodenseitigen umlaufenden Rohrgestänge fixiert, wobei das Stützelement ansonsten frei von einer direkten festen Verbindung mit dem Kunststoff-Eckfuß ist und somit keine Spannungen auf diesen ausübt. support. Since the support element is stressed in practice less by tensile load but much more by strong pressure load, the upper cover part of the hollow support member within the plastic Eckfußes upwards firmly connected to the running on the outer edge of the upper support plate angle rail (eg. riveted or screwed) and fixed down to the lower bottom part on the bottom-side circumferential pipe string, the support element is otherwise free of a direct solid connection with the plastic Eckfuß and thus exerts no tension on this.

Erläuterung der vorliegenden Erfindung nicht von Bedeutung und wird von daher nicht weiter beschrieben. Die vorliegende Erfindung zielt vielmehr auf die Kunststoff- Eckfüße 22 mit den eingebauten Stützelementen 30 ab. Die Darstellung in Fig. 3 soll das Verständnis für den Aufbau der Composite-Palette erleichtern und letztendlich die Positionierung des Stützelements 30 verdeutlichen. Dazu ist die Composite- Palette in Figur 4 noch weiter "entblättert" und nun auch ohne die Kunststoff-Eckfüße in perspektivischer Ansicht dargestellt, so dass nun die Anordnung der vier Explanation of the present invention is not important and is therefore not further described. Rather, the present invention aims at the plastic corner feet 22 with the built-in support elements 30. The illustration in Fig. 3 is intended to facilitate understanding of the structure of the composite pallet and ultimately illustrate the positioning of the support member 30. For this purpose, the composite pallet in Figure 4 is still "defoliated" and now shown without the plastic corner feet in a perspective view, so now the arrangement of the four
Stützelemente 30 ersichtlich wird, was ja im Normalfall nicht gegeben ist, da die Support elements 30 can be seen, which is normally not given, since the
Stützelemente von außen nicht sichtbar innerhalb der Kunststoff-Eckfüße fixiert sind. Support elements are not visible from the outside fixed inside the plastic corner feet.
Die konstruktive Formgebung eines Stützelements 30 ist konkret in Figur 5 in perspektivischer Ansicht dargestellt. Hier wird deutlich, dass das Stützelement 30 aus einem stabilen länglichen Stahlblechstreifen besteht und zu einem hohlen rohrförmigen The constructive shaping of a support element 30 is shown concretely in FIG. 5 in a perspective view. Here it is clear that the support member 30 consists of a stable elongated sheet steel strip and a hollow tubular
Stützkörper eingeformt, bzw. eingefaltet und eingebogen ist. Durch wechselseitige Einbiegungen des länglichen Stahlblechstreifens ist das hohle Stützelement 30 derart ausgebildet, dass es eine ebene Seitenwandung 34 (rückwärtige Basis-Seitenwandung) und zwei gegenüberliegende V-förmig nach innen eingeformte Seitenwandungen 36 aufweist. Durch weitere Einbiegungen der ebenen Seitenwandung 34 wurde dem hohlen Stützelement 30 am oberen und unteren Ende jeweils ein oberes Deckelteil 38 und ein Bodenteil 40 angeformt, wobei das obere Deckelteil 38 und das untere Support body formed, or folded and inflected. By mutual bends of the elongated sheet steel strip, the hollow support member 30 is formed so as to have a flat side wall 34 (rear base side wall) and two opposite V-shaped inwardly molded side walls 36. By further inflections of the flat side wall 34, the hollow support member 30 at the upper and lower end in each case an upper cover part 38 and a bottom part 40 was formed, wherein the upper cover part 38 and the lower
Bodenteil 40 des Stützelements 30 jeweils die beiden V-förmig nach innen eingeformten Seitenwandungen 36 überdecken und sich gegen diese abstützen. Die Wanddicke des Stahlblechstreifens beträgt etwa 2 mm, die Abmessungen des Stützelements 30 betragen in der Höhe ca. 90 mm und für das Deckel- bzw. Bodenteil etwa 40 x 40 mm. Base part 40 of the support member 30 respectively cover the two V-shaped inwardly molded side walls 36 and are supported against them. The wall thickness of the Sheet steel strip is about 2 mm, the dimensions of the support member 30 are in height about 90 mm and for the lid or bottom part about 40 x 40 mm.
Die am linken Rand des Stützelements 30 erkennbare "Verzahnung" stellt die The recognizable at the left edge of the support member 30 "gearing" represents the
Verbindungs-linie zwischen linker eingewinkelter Seitenwandung 36 und ebener rückwärtiger Basis-Seitenwandung 34 dar. Es handelt sich hier um eine Vielzahl von Stanzlöchern, die das Einbiegen der beiden eingewinkelten Seitenwandungen 36 um einen Winkel von größer 90 ° (hier ca. 135 °) erleichtern. Connecting line between the left-angled side wall 36 and planar rearward base side wall 34. This is a variety of punched holes, which facilitate the bending of the two angled side walls 36 by an angle of greater than 90 ° (here about 135 °) ,
Figur 6 zeigt noch eine Bodenansicht auf das Stützelement 30 gemäß Fig. 5, mit Blick auf das untere Bodenteil 40, das um einen 90°-Winkel aus der oben ersichtlichen ebenen rückwärtigen Basis-Seitenwandung 34 heruntergebogen wurde. In gleicher Weise wurde das obere Deckelteil 38, von dem hier nur ein kurzes Stück ersichtlich ist, um 90° von der ebenen rückwärtigen Basis-Seitenwandung 34 umgebogen. Von den beiden eingewinkelten Seitenwandungen 36 ist hier auch nur jeweils ein Stück zu sehen. Im eingebauten Normalfall stützt sich das obere Deckelteil 38 von oben und das untere Bodenteil 40 von unten gegen die beiden eingewinkelten Seitenwandungen 36 ab. Das hier voll ersichtliche untere Bodenteil 40 weist eine etwas außermittig angebrachte Bohrung mit Seitenschlitz 44 und Gewindeeinformung für das FIG. 6 also shows a bottom view of the support element 30 according to FIG. 5, with a view of the lower floor part 40, which has been bent downwards by a 90 ° angle from the above-described planar rearward base side wall 34. In the same way, the upper cover part 38, of which only a short distance can be seen here, was bent by 90 ° from the flat rear base side wall 34. Of the two angled side walls 36 only one piece can be seen here. In the built-in normal case, the upper lid portion 38 is supported from above and the lower bottom portion 40 from below against the two angled side walls 36 from. The here fully apparent lower bottom portion 40 has a slightly eccentric mounted bore with side slot 44 and thread recess for the
Einschrauben einer Gewindeschraube auf. Wie gerade noch ersichtlich weist das obere Deckelteil 38 am Seitenrand eine einfache Bohrung 42 zum Einbringen einer Screw in a threaded screw. As can be seen, the upper lid portion 38 has a simple bore 42 for insertion at the side edge
Nietverbindung auf. Rivet connection on.
Schließlich ist in Figur 7 noch eine perspektivische Teilansicht außenseitig auf eine Ecke der Composite-Palette dargestellt, bei welcher der Kunststoff-Eckfuß 22 vorderseitig aufgeschnitten ist, so dass das fest eingebaute Stützelement 30 sichtbar wird, das oben mittels einer Nietverbindung (durch einfache Bohrung 42) fest gegen eine obere, auf dem äußeren Rand der oberen Tragplatte 20 verlaufende Finally, FIG. 7 also shows a perspective partial view on the outside on a corner of the composite pallet, in which the plastic corner foot 22 is cut open on the front, so that the fixedly installed support element 30 becomes visible, which by means of a riveted connection (by a simple bore 42 ) firmly against an upper, on the outer edge of the upper support plate 20 extending
Winkelschiene 32 vernietet ist und unten mittels einer von unten eingedrehten Bracket rail 32 is riveted and bottom by means of a screwed from below
Senkkopf-Gewindeschraube 46 (durch die etwas außermittig angebrachte Bohrung mit Seitenschlitz 44 und Gewindeeinformung) fest mit dem umlaufenden Boden- Rohrgestänge 26 verschraubt ist. Dabei ist der Kunststoff-Eckfuß 22 frei von einer direkten festen Verbindung mit dem Stützelement 30 oder dessen Verbindungsmitteln. Direkt in das Kunststoffmaterial der Kunststoff-Eck- und Mittelfüße (22, 24) eingedrehte Befestigungsschrauben, die bei Überbeanspruchung oftmals herausgerissen werden, entfallen an dieser Stelle. Countersunk screw 46 (through the slightly eccentrically mounted bore with side slot 44 and thread molding) is firmly bolted to the revolving floor pipe string 26. In this case, the plastic Eckfuß 22 is free of a direct solid connection with the support member 30 or its connection means. Fixing screws screwed directly into the plastic material of the plastic corner and middle feet (22, 24), which are often torn out in the event of overstress, are omitted here.
Die vorliegende erfindungsgemäße Lösung liefert sozusagen als Nebeneffekt den Vorteil, dass auf eine zusätzliche elektrische Ableitvorrichtung der üblicherweise nicht leitfähigen Kunststoff-Füße verzichtet werden kann. Bei UL-IBCs und deren Verwendung für leicht entzündliche oder explosionsgefährdete flüssige Füllgüter ist gemäß der erforderlichen Zulassungsverordnung eine Vorrichtung bzw. Maßnahme zur Ableitung elektrischer Ladungen in den Standboden zwingend vorgeschrieben. Die Stützelemente 30 in den vier Kunststoff-Eckfüßen 22 sind einerseits nach oben mit dem äußeren Rand der oberen Stahlblech-Tragplatte 20 verlaufenden Stahlblech-Winkelschiene 32 (sowie dem The present inventive solution provides as a side effect the advantage that can be dispensed with an additional electrical discharge of the usually non-conductive plastic feet. In the case of UL-IBCs and their use for highly flammable or potentially explosive liquid products, a device or measure for discharging electrical charges into the floor is mandatory in accordance with the required approval ordinance. The support members 30 in the four plastic corner feet 22 are on the one hand upwardly with the outer edge of the upper sheet steel support plate 20 extending sheet steel angle rail 32 (and the
Rohrgitterrahmen 12) und andererseits mit dem unten umlaufenden Boden-Rohrgestänge 26 verschraubt. Dadurch ist eine Erdung des ableitfähigen Blasteils = Kunststoff- Innenbehälters über die leitfähige Innenschicht zur Gewebeaußenseite der Feuerschutz- Isoliermatte 28 und damit zum Rohrgitterrahmen 12 bzw. der Bodenpalette 14 Rohrgitterrahmen 12) and on the other hand screwed to the bottom rotating bottom pipe frame 26. As a result, a grounding of the dissipative blow molding = plastic inner container via the conductive inner layer to the fabric outer side of the fire protection insulating mat 28 and thus to the pipe frame 12 and the bottom pallet 14th
gewährleistet. guaranteed.
Die zuvor aufgezeigten Merkmale der vorliegenden Erfindung ermöglichen es, einen besonderen Palettencontainer mit Flammschutz-Vorrichtung = UL-IBC auch mit einer Composite-Palette mit sonst hitzeempfindlichen Kunststoff-Palettenfüßen derart auszubilden, dass er wenigstens für eine Dauer von ca. 25 Minuten einer äußeren The above-mentioned features of the present invention make it possible to form a special pallet container with flame retardant device = UL-IBC also with a composite pallet with otherwise heat-sensitive plastic palette feet such that it at least for a duration of about 25 minutes of an outer

Durch diese erfindungsgemäßen Maßnahmen wird erreicht, dass bei Hitzeeinwirkung durch Feuer und beginnender Erweichung des thermoplastischen Kunststoffmaterials der Palettenfüße ein einseitiges Einknicken der Palettenfüße und ein nachfolgendes By these measures according to the invention it is achieved that when exposed to heat by fire and softening of the thermoplastic plastic material of the pallet feet a one-sided buckling of the pallet feet and a subsequent
Umstürzen von zwei befüllten übereinandergestapelten UL-IBCs verhindert wird. Overslipping of two filled stacked UL IBCs is prevented.
Fazit : Die Kunststoff-Eckfüße von "normalen" Composite-Paletten stellen bei einer Verwendung für UL-IBCs einen Schwachpunkt dar, der wie aus der vorherigen Conclusion: The plastic corner feet of "normal" composite pallets are a weak point when used for UL IBCs, as in the previous one
