Definitions
- the present invention relates to a pallet-like base frame for a transport and storage container for liquids, as well as a transport and storage container with such a base frame, wherein the base frame has a base for supporting an inner container accommodated in an outer casing made of metal, preferably designed as a grid, as well as corner feet and center feet.
- EP 2 426 067 A1 discloses a pallet-like base frame for a transport and storage container, which has a base for supporting an inner container of the transport and storage container, which is connected via corner and center feet to a base frame, which forms a support surface for the transport and storage container.
- all components are made of metal, so that the base frame is characterized by particular stability.
- the known pallet-like base frame serves as a base frame for transport and storage containers, which have an inner container accommodated in an outer casing on the floor of the base frame and can be arranged on top of one another in a stack arrangement, whereby the The base frame, designed as a tubular frame, enables easy access to the spaces between the stacked transport and storage containers despite the stacking arrangement.
- Such a composite pallet is known from WO 2007/087857 A1, in which a base made of metal is provided, which is connected to a base frame or runners made of plastic via corner and center feet made of plastic.
- the use of plastic enables low-wear contact between the pallet-like base frame and a conveyor device.
- the known pallet-like base frame has reduced robustness due to the plastic material used. It has also been found that contact between the plastic material and a conveyor device can easily cause the plastic material to be abraded as a result of friction, so that the pallet-like base frame is subject to progressive wear when used in conveyor devices.
- the removed plastic material can contaminate the environment of the respective conveyor device in an undesirable manner, for example in the form of so-called microplastics.
- the present invention is therefore based on the object of providing a pallet-like underframe and a transport and storage container with a to propose such a subframe which, on the one hand, has a high level of stability and robustness and, on the other hand, enables conveying on a conveyor system with as little wear as possible.
- the pallet-like base frame for a transport and storage container for liquids has a base for supporting an inner container accommodated in an outer casing made of metal, preferably designed as a grid, as well as corner feet and center feet, wherein the corner feet and the center feet are arranged on runners and connect the runners to the base, wherein the runners each form a contact surface and are made of sheet metal.
- the support surface of the base frame is therefore made of metal or sheet metal. Because the pallet-like base frame rests on a base via runners, the support surface of the base frame is many times larger than would be the case with a base frame with a surrounding metal tube or a frame profile. The weight of the transport and storage container is then distributed over a large area of the support surface, resulting in a comparatively lower support force per unit area and enabling the pallet-like base frame to be conveyed with a conveyor device with little wear. In addition, undesirable abrasion of plastic material on the pallet-like base frame can be avoided.
- the corner feet, center feet and/or the base can in principle be made of any suitable material, such as wood, plastic or the like.
- the runners can be designed with stiffening beads running along the runners, whereby the stiffening beads form lower chords. which form the contact surface.
- the stiffening beads can in principle be designed with any shape relative to a cross-section of the respective runner and can run along the runners or in the direction of a longitudinal axis of the respective runner.
- One or a plurality of stiffening beads, for example three stiffening beads, can be formed.
- the stiffening beads can essentially run along the entire length of the respective runner or only in sections on the respective runner.
- the lower chords can run flat or parallel to a substrate or the floor of the underframe, so that the contact surface formed by the lower chords of the runners is as large as possible.
- the stiffening beads can be designed with webs that run between the upper chords and the lower chords of the stiffening beads.
- the cross-sectional shape of the upper chords is in principle arbitrary, since they are not primarily used to rest on a surface.
- the webs can be designed to run straight or curved between the upper chords and the lower chords.
- the upper chords and the lower chords together with the webs can be designed to be trapezoidal, curved or wave-shaped relative to a cross-section of the respective runner.
- a transition between the webs, the upper chords and the lower chords can be designed with a radius. This type of shape allows the runners to be made particularly light and bend-stable from a comparatively thin metal sheet.
- the runners can be designed with an edge web at least in sections. Longitudinal edges of the runners can be formed by bottom chords, whereby it can also be provided that an edge web is formed on the bottom chords.
- the edge web can run along the entire length of a runner or only in sections. It can also be provided that the edge web is interrupted in sections.
- the runners can be equipped, at least in sections, with a reduced threshold at a height of the respective runner above the contact surface. le and/or an approach slope.
- the height of the respective runner above the ground can then be reduced so that the runner can easily be driven over by a conveyor, for example a pallet truck. If the runners are designed with an edge web, this can be interrupted in the area of the crossing threshold. Alternatively or additionally, an approach slope can be designed on the runner so that the conveyor can be moved more easily over the runner.
- the crossing threshold can also be designed, among other things, by making any stiffening beads that may be present in an area of the crossing threshold comparatively low. For example, stiffening beads can be provided which have a reduced height in the area of the crossing threshold.
- the corner feet, center feet and/or the base can be made of metal. If the corner feet and center feet are also made of metal, the pallet-like base frame is particularly robust and stable. The pallet-like base frame can also be made free of plastic material.
- the runners can each be designed with weld bosses and/or with through holes for a screw connection to the corner feet and the center feet.
- Each of the runners can have a plurality of weld bosses.
- the weld bosses can be embossed into the metal sheet of the runners.
- the weld bosses are designed at the respective ends of the runners and, if necessary, in a central region of the runners, for example for connection to corner feet and/or center feet. This then makes it possible to easily weld the runners, in particular to the corner feet and/or center feet.
- the corner feet, center feet and/or the runners can be designed as one-piece deep-drawn bodies made of sheet metal. This means that the number of parts of the base frame can be reduced as much as possible.
- the corner feet, center feet and/or the runners can also be produced cost-effectively in large quantities by deep-drawing metal sheets.
- the runners can be designed symmetrically. This makes it possible to further reduce the number of different parts of the base frame and to simplify assembly of the base frame.
- the runners can be designed to be axially symmetrical or point symmetrical, so that the positioning of a runner in relation to a central foot or a corner foot is arbitrary. This means that runners can also be designed in the same way, regardless of whether the respective runner is mounted on a specific side of the base frame. Alternatively, the runners can also be designed asymmetrically.
- the underframe can be designed with just two outer runners or with one middle runner and two outer runners.
- the middle runner and the two outer runners can be arranged parallel to each other.
- the middle runner can then be arranged between the two outer runners. If the runners are designed symmetrically, the two outer runners can be designed identically. This simplifies the manufacture of the underframe.
- the middle skid can form a central foot of the underframe.
- the central foot can be formed, for example, by the central foot being embossed into the middle skid.
- the middle skid can then be formed with an arched or roof-shaped central foot in its middle.
- the central foot can be formed by two legs that are formed differently from a longitudinal extension of the middle skid and thus form a U- or V-shaped elevation of the middle skid.
- Two opposing center feet can be connected to one another via a floor cross member, or the floor cross member can form the two opposing center feet.
- the floor cross member can be designed in the manner of a runner as a one-piece deep-drawn body made of sheet metal and have stiffening beads.
- the floor cross member can be designed such that it connects two opposing center feet, which in turn are designed as one-piece deep-drawn bodies made of sheet metal.
- the floor cross member is then comparatively flat.
- the floor cross member can form the two opposing center feet in that the floor cross member has center foot bodies at their respective longitudinal ends, which in turn have a U-shaped or V-shaped cross-section relative to a longitudinal axis of the center runner.
- the respective center foot can then be designed with a base wall, an outer leg wall, and an inner leg wall.
- the base wall and the leg walls can be formed at axial end regions of the metatarsal in a plane transverse to a longitudinal axis of the metatarsal and form a U-shaped edge web.
- a central foot of the base frame can be connected directly to the floor cross member by means of a detachable connection.
- a bowl-like depression can be formed in the floor cross member, which extends in the direction of the central foot. This allows a weight force of the inner container to be advantageously introduced into the central foot via the floor cross member.
- the detachable connection can be a screw connection, for example. The screw connection can be easily formed using a single, central sheet metal screw.
- a positive locking device is formed between the central foot and the floor crossbeam. This can prevent the middle skid screwed to the floor crossbeam from moving or twisting relative to the floor crossbeam. The position of the middle skid relative to the floor crossbeam can then be securely fixed so that the middle skid is in contact with the floor crossbeam. can be mounted.
- the anti-twisting device can be created inexpensively, for example, by means of tabs formed in the middle skid that engage in holes in the base cross member or vice versa. The tabs can be created by embossing and the holes by punching. If the middle skid and the base cross member are made by deep drawing, the tabs or the holes can be created without any further work step during the deep drawing.
- the central runner can be welded to a central foot and directly screwed to a cup-shaped central foot formed by the floor opposite this.
- the central runner can be welded to the central foot using resistance butt welding, for example.
- the central foot can then be firmly fixed to one end of the central runner, so that the central runner and the central foot together form an assembly of the base frame. If the floor is formed with a cup-shaped central foot, i.e. the central foot is formed into the floor, the floor or the central foot formed in it can simply be screwed to the central runner when assembling the base frame.
- the outer runners can be welded to the corner feet and/or the center feet.
- the outer runners can be welded by resistance butt welding.
- the outer runners can be connected to the corner feet using, for example, two, preferably four welding points.
- the corner feet can thus be securely attached to the outer runners so that they cannot move.
- the center feet can also be welded to the outer runners using at least two welding points. If the center feet are formed by a floor crossbeam, a component group consisting of corner feet, center feet and outer runners can be formed, which can be formed and handled in just a few work steps as part of a manufacturing process for the base frame. Furthermore, the connections of the floor to the corner feet and the center feet can be designed as detachable connections.
- the subframe can then be made up of two or three assemblies which are brought together to form the subframe in a final assembly step.
- One assembly can, for example, be made up of outer runners with corner feet, center feet and a floor cross member, another assembly can be made up of a center runner with a center foot, and a third assembly can be made up of the floor, whereby the floor can also form a center foot. If the connections between the corner feet, center feet and runners are made by welding, the corner feet and center feet can be precisely positioned or fixed in the position intended for connection to the floor. In this way, it is then easy to screw the floor to the corner feet and the center feet in a final assembly step. This screw connection can also be made in such a way that an outer shell of a transport and storage container is screwed together with these screws at the same time.
- the runners can form the corner feet and/or the middle feet of the base frame. Then it is no longer necessary to connect the corner feet and/or the middle feet to the runners.
- the corner feet and/or the middle feet can be formed, for example, by the corner feet and/or the middle feet being embossed into outer runners.
- the respective runner can then be formed with an arched or roof-shaped middle foot in its middle.
- the corner feet can each be formed by two legs that are formed deviating from a longitudinal extension of the runner and thus form a U- or V-shaped elevation of the runner.
- Outer edges of the contact surface of the runners can be designed in such a way that the outer edges are at least partially overhanged by the corner feet and the undercarriage with the outer edges is within an inner edge of an upper frame profile of the outer casing of the transport and storage container.

Abstract
Description
Palettenartiges Untergestell für einen Transport- und Lagerbehälter sowie Transport- und Lagerbehälter mit einem derartigen Untergestell Pallet-like underframe for a transport and storage container as well as transport and storage containers with such an underframe
Die vorliegende Erfindung betrifft ein palettenartiges Untergestell für einen Transport- und Lagerbehälter für Flüssigkeiten, sowie einen Transport- und Lagerbehälter mit einem derartigen Untergestell, wobei das Untergestell einen Boden zur Abstützung eines in einem vorzugsweise als Gitter ausgeführten Außenmantel aus Metall aufgenommenen Innenbehälter sowie Eckfüße und Mittelfüße aufweist. The present invention relates to a pallet-like base frame for a transport and storage container for liquids, as well as a transport and storage container with such a base frame, wherein the base frame has a base for supporting an inner container accommodated in an outer casing made of metal, preferably designed as a grid, as well as corner feet and center feet.
Aus der EP 2 426 067 Al ist ein palettenartiges Untergestell für einen Transport- und Lagerbehälter bekannt, das einen Boden zur Abstützung eines Innenbehälters des Transport- und Lagerbehälters aufweist, der über Eck- und Mittelfüße mit einem Grundrahmen verbunden ist, welcher eine Aufstandsfläche des Transport- und Lagerbehälters ausbildet. Bei dem bekannten palettenartigen Untergestell sind sämtliche Bestandteile aus Metall gefertigt, so dass sich das Untergestell durch eine besondere Stabilität auszeichnet. EP 2 426 067 A1 discloses a pallet-like base frame for a transport and storage container, which has a base for supporting an inner container of the transport and storage container, which is connected via corner and center feet to a base frame, which forms a support surface for the transport and storage container. In the known pallet-like base frame, all components are made of metal, so that the base frame is characterized by particular stability.
Weiter dient das bekannte palettenartige Untergestell als Untergestell für Transport- und Lagerbehälter, die auf dem Boden des Untergestells einen in einem Außenmantel aufgenommenen Innenbehälter aufweisen und in einer Stapelanordnung aufeinander angeordnet werden können, wobei der als Rohrrahmen ausgebildete Grundrahmen trotz der Stapelanordnung eine einfache Zugänglichkeit der zwischen den aufgestapelten Transport- und Lagerbehältern ausgebildeten Zwischenräume ermöglicht. Furthermore, the known pallet-like base frame serves as a base frame for transport and storage containers, which have an inner container accommodated in an outer casing on the floor of the base frame and can be arranged on top of one another in a stack arrangement, whereby the The base frame, designed as a tubular frame, enables easy access to the spaces between the stacked transport and storage containers despite the stacking arrangement.
Die besondere Robustheit des bekannten Untergestells, die sich insbesondere hinsichtlich einer hohen Lebensdauer des bekannten palettenartigen Untergestells als vorteilhaft erweist, kann j edoch in Kontakt mit Fördereinrichtungen dazu führen, dass es bei den Fördereinrichtung die häufig als Förderrollen, Förderbänder oder dergleichen ausgeführt sind, zu einem erhöhten Verschleiß kommt, so dass man zur Verschleißminderung mittlerweile dazu übergegangen ist, vollständig aus Kunststoff gefertigte Untergestelle oder Untergestelle zu verwenden, die sowohl Komponenten aus einem Kunststoffmaterial als auch Komponenten aus Metall aufweisen. The particular robustness of the known base frame, which proves to be advantageous in particular with regard to a long service life of the known pallet-like base frame, can, however, lead to increased wear in the conveyor devices, which are often designed as conveyor rollers, conveyor belts or the like, when in contact with conveyor devices, so that in order to reduce wear, it has now become the case to use base frames made entirely of plastic or base frames which have both components made of a plastic material and components made of metal.
Eine derartige Composite-Palette ist aus der WO 2007/087857 A l bekannt, bei der ein aus Metall gefertigter Boden vorgesehen ist, der über aus Kunststoff gefertigte Eck- und Mittelfüße mit einem Grundrahmen oder Kufen aus Kunststoff verbunden ist. Durch die Verwendung des Kunststoffs wird ein verschleißarmer Kontakt des palettenartigen Untergestells zu einer Fördereinrichtung ermöglicht. Gleichwohl weist das bekannte palettenartige Untergestell aufgrund des verwendeten Kunststoffmaterials eine verminderte Robustheit auf. Weiter hat sich herausgestellt, dass durch einen Kontakt des Kunststoffmaterials mit einer Fördereinrichtung das Kunststoffmaterial in Folge von Reibung leicht abrasiv abgetragen werden kann, so dass das palettenartige Untergestell bei einer Verwendung in Fördereinrichtungen einem fortschreitenden Verschleiß unterworfen ist. Darüber hinaus kann das abgetragene Kunststoffmaterial eine Umgebung der j eweiligen Fördereinrichtung, beispiel sweise in Form von sogenanntem Mikroplastik, in unerwünschter Weise kontaminieren. Such a composite pallet is known from WO 2007/087857 A1, in which a base made of metal is provided, which is connected to a base frame or runners made of plastic via corner and center feet made of plastic. The use of plastic enables low-wear contact between the pallet-like base frame and a conveyor device. Nevertheless, the known pallet-like base frame has reduced robustness due to the plastic material used. It has also been found that contact between the plastic material and a conveyor device can easily cause the plastic material to be abraded as a result of friction, so that the pallet-like base frame is subject to progressive wear when used in conveyor devices. In addition, the removed plastic material can contaminate the environment of the respective conveyor device in an undesirable manner, for example in the form of so-called microplastics.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein palettenartiges Untergestell sowie einen Transport- und Lagerbehälter mit ei- nem derartigen Untergestell vorzuschlagen, das bzw. der einerseits eine hohe Stabilität bzw. große Robustheit aufweist, und andererseits eine möglichst verschleißarme Förderung auf einer Fördereinrichtung ermöglicht. The present invention is therefore based on the object of providing a pallet-like underframe and a transport and storage container with a to propose such a subframe which, on the one hand, has a high level of stability and robustness and, on the other hand, enables conveying on a conveyor system with as little wear as possible.
Diese Aufgabe wird durch ein palettenartiges Untergestell mit den Merkmalen des Anspruchs 1 und einen Transport- und Lagerbehälter mit den Merkmalen des Anspruchs 20 gelöst. This object is achieved by a pallet-like underframe having the features of claim 1 and a transport and storage container having the features of claim 20.
Das palettenartige Untergestell für einen Transport- und Lagerbehälter für Flüssigkeiten weist einen Boden zur Ab stützung eines in einem vorzugsweise als Gitter ausgeführten Außenmantel aus Metall aufgenommenen Innenbehälters sowie Eckfüße und Mittelfüße auf, wobei die Eckfüße und die Mittelfüße auf Kufen angeordnet sind und die Kufen mit dem Boden verbinden, wobei die Kufen j eweils eine Aufstandsfläche ausbilden und aus Metallblech gefertigt sind. The pallet-like base frame for a transport and storage container for liquids has a base for supporting an inner container accommodated in an outer casing made of metal, preferably designed as a grid, as well as corner feet and center feet, wherein the corner feet and the center feet are arranged on runners and connect the runners to the base, wherein the runners each form a contact surface and are made of sheet metal.
Erfindungsgemäß ist daher vorgesehen, die Aufstandsfläche des Untergestells aus Metall bzw. Metallblech auszubilden. Dadurch, dass das palettenartige Untergestell über Kufen auf einem Untergrund aufliegt, ist die Aufstandsfläche des Untergestells um ein Vielfaches größer, als dies bei einem Grundrahmen mit einem umlaufenden Metallrohr bzw. einem Rahmenprofil der Fall wäre. Ein Gewicht des Transport- und Lagerbehälters ist dann großflächig über die Aufstandsfläche verteilt, so dass sich eine vergleichsweise geringere Auflagekraft pro Flächeneinheit ergibt und eine verschleißarme Förderung des palettenartigen Untergestells mit einer Fördereinrichtung ermöglicht wird. Darüber hinaus kann ein unerwünschter Abrieb von Kunststoffmaterial an dem palettenartigen Untergestell vermieden werden. Die Eckfüße, Mittelfüße und/oder der Boden können prinzipiell aus einem beliebigen, geeigneten Material, wie Holz, Kunststoff oder dergleichen gefertigt sein. According to the invention, the support surface of the base frame is therefore made of metal or sheet metal. Because the pallet-like base frame rests on a base via runners, the support surface of the base frame is many times larger than would be the case with a base frame with a surrounding metal tube or a frame profile. The weight of the transport and storage container is then distributed over a large area of the support surface, resulting in a comparatively lower support force per unit area and enabling the pallet-like base frame to be conveyed with a conveyor device with little wear. In addition, undesirable abrasion of plastic material on the pallet-like base frame can be avoided. The corner feet, center feet and/or the base can in principle be made of any suitable material, such as wood, plastic or the like.
Die Kufen können mit entlang der Kufen verlaufenden Versteifungssicken ausgebildet sein, wobei die Versteifungssicken Untergurte ausbil- den können, die die Aufstandsfläche ausbilden. Die Versteifungssicken können relativ bezogen auf einen Querschnitt der jeweiligen Kufe, prinzipiell mit einer beliebigen Form ausgebildet sein und längs der Kufen bzw. in Richtung einer Längsachse der j eweiligen Kufe verlaufen. Dabei können eine oder eine Mehrzahl von Versteifungssicken, beispielsweise drei Versteifungssicken, ausgebildet sein. Die Versteifungssicken können im Wesentlichen entlang einer Gesamtlänge der j eweiligen Kufe oder nur ab schnittsweise an der j eweiligen Kufe verlaufen. Die Untergurte können flach bzw. parallel zu einem Untergrund bzw. dem Boden des Untergestells verlaufen, so dass sich eine möglichst große Aufstandsfläche ergibt, die durch die Untergurte der Kufen ausgebildet i st. The runners can be designed with stiffening beads running along the runners, whereby the stiffening beads form lower chords. which form the contact surface. The stiffening beads can in principle be designed with any shape relative to a cross-section of the respective runner and can run along the runners or in the direction of a longitudinal axis of the respective runner. One or a plurality of stiffening beads, for example three stiffening beads, can be formed. The stiffening beads can essentially run along the entire length of the respective runner or only in sections on the respective runner. The lower chords can run flat or parallel to a substrate or the floor of the underframe, so that the contact surface formed by the lower chords of the runners is as large as possible.
Die Versteifungssicken können mit Stegen ausgebildet sein, die zwischen Obergurten und den Untergurten der Versteifungssicken verlaufen. Eine Querschnittsform der Obergurte i st prinzipiell beliebig, da diese nicht primär zur Auflage an einer Fläche dienen. Die Stege können gerade oder gebogen zwischen den Obergurten und den Untergurten verlaufend ausgebildet sein. Die Obergurte und die Untergurte können zusammen mit den Stegen relativ bezogen auf einen Querschnitt der j eweiligen Kufe trapezförmig, bogenförmig oder wellenförmig ausgebildet sein. Ein Übergang zwi schen den Stegen, den Obergurten und den Untergurten kann mit einem Radius ausgebildet sein. Durch eine derartige Formgebung können die Kufen aus einem vergleichsweise dünnen Metallblech besonders leicht und biegestabil ausgebildet werden. The stiffening beads can be designed with webs that run between the upper chords and the lower chords of the stiffening beads. The cross-sectional shape of the upper chords is in principle arbitrary, since they are not primarily used to rest on a surface. The webs can be designed to run straight or curved between the upper chords and the lower chords. The upper chords and the lower chords together with the webs can be designed to be trapezoidal, curved or wave-shaped relative to a cross-section of the respective runner. A transition between the webs, the upper chords and the lower chords can be designed with a radius. This type of shape allows the runners to be made particularly light and bend-stable from a comparatively thin metal sheet.
Die Kufen können zumindest abschnittsweise mit einem Randsteg ausgebildet sein. Längsränder der Kufen können durch Untergurte ausgebildet sein, wobei auch vorgesehen sein kann, dass hier ein Randsteg an den Untergurten ausgebildet ist. Der Randsteg kann entlang einer gesamten Länge einer Kufe verlaufen oder auch nur abschnittsweise. Auch kann vorgesehen sein, dass der Randsteg ab schnittsweise unterbrochen ist. The runners can be designed with an edge web at least in sections. Longitudinal edges of the runners can be formed by bottom chords, whereby it can also be provided that an edge web is formed on the bottom chords. The edge web can run along the entire length of a runner or only in sections. It can also be provided that the edge web is interrupted in sections.
Die Kufen können zumindest ab schnittswei se mit einer in einer Höhe der j eweiligen Kufe über der Aufstandsfläche verminderten Überfahrschwel- le und/oder einer Anfahrschräge ausgebildet sein. Die Höhe der j eweiligen Kufe über einem Untergrund kann dann so vermindert sein, dass die Kufe leicht von einem Fördermittel, beispielsweise mit einem Hubwagen, überfahren werden kann. Sofern die Kufen mit einem Randsteg ausgebildet sind, kann dieser im Bereich der Überfahrschwelle unterbrochen sein. Alternativ oder ergänzend kann an der Kufe ein Anfahrschräge ausgebildet sein, so dass das Fördermittel leichter über die Kufe hinwegbewegt werden kann. Die Überfahrschwelle kann unter anderem auch dadurch ausgebildet sein, dass in einem Bereich der Überfahrschwelle eventuell vorhandene Versteifungssicken vergleichsweise niedrig ausgebildet sind. So können Versteifungssicken vorgesehen sein, die im Bereich der Überfahrschwelle eine verminderte Höhe aufweisen. The runners can be equipped, at least in sections, with a reduced threshold at a height of the respective runner above the contact surface. le and/or an approach slope. The height of the respective runner above the ground can then be reduced so that the runner can easily be driven over by a conveyor, for example a pallet truck. If the runners are designed with an edge web, this can be interrupted in the area of the crossing threshold. Alternatively or additionally, an approach slope can be designed on the runner so that the conveyor can be moved more easily over the runner. The crossing threshold can also be designed, among other things, by making any stiffening beads that may be present in an area of the crossing threshold comparatively low. For example, stiffening beads can be provided which have a reduced height in the area of the crossing threshold.
Die Eckfüße, Mittelfüße und/oder der Boden können aus Metall gefertigt sein. Wenn die Eckfüße und die Mittelfüße ebenfall s aus Metall ausgebildet sind, ist das palettenartige Untergestell besonders robust und stabil . So kann das palettenartige Untergestell auch frei von Kunststoffmaterial ausgebildet sein. The corner feet, center feet and/or the base can be made of metal. If the corner feet and center feet are also made of metal, the pallet-like base frame is particularly robust and stable. The pallet-like base frame can also be made free of plastic material.
Die Kufen können j eweils mit Schweißbuckeln und/oder mit Durchgangsöffnungen einer Schraubverbindung mit den Eckfüßen und den Mittelfüßen ausgebildet sein. Jede der Kufen kann eine Mehrzahl von Schweißbuckeln aufweisen. Die Schweißbuckel können in das Metallblech der Kufen eingeprägt sein. Insbesondere kann vorgesehen sein, dass die Schweißbuckel an den j eweiligen Enden der Kufen, und wenn erforderlich in einem Mittelbereich der Kufen, beispielsweise zur Verbindung mit Eckfüßen und/oder Mittelfüßen, ausgebildet sein. So wird es dann auch möglich die Kufen insbesondere mit den Eckfüßen und/oder Mittelfüßen einfach zu verschweißen. Alternativ oder ergänzend ist es auch möglich die Eckfüße und die Mittelfüße mit den Kufen mittels Schrauben zu verbinden. Dies ist besonders vorteilhaft, wenn die Eckfüße und die Mittelfüße nicht aus Metall ausgebildet sind. Die Eckfüße, Mittelfüße und/oder die Kufen können als einstückige Tiefziehkörper aus Metallblech ausgebildet sein. Dadurch kann eine Teileanzahl des Untergestells soweit als möglich zu vermindert werden. Auch können durch Tiefziehen von Metallblechen die Eckfüße, die Mittelfüße bzw. die Kufen in großer Stückzahl kostengünstig hergestellt werden. The runners can each be designed with weld bosses and/or with through holes for a screw connection to the corner feet and the center feet. Each of the runners can have a plurality of weld bosses. The weld bosses can be embossed into the metal sheet of the runners. In particular, it can be provided that the weld bosses are designed at the respective ends of the runners and, if necessary, in a central region of the runners, for example for connection to corner feet and/or center feet. This then makes it possible to easily weld the runners, in particular to the corner feet and/or center feet. Alternatively or additionally, it is also possible to connect the corner feet and the center feet to the runners using screws. This is particularly advantageous if the corner feet and the center feet are not made of metal. The corner feet, center feet and/or the runners can be designed as one-piece deep-drawn bodies made of sheet metal. This means that the number of parts of the base frame can be reduced as much as possible. The corner feet, center feet and/or the runners can also be produced cost-effectively in large quantities by deep-drawing metal sheets.
Die Kufen können symmetrisch ausgebildet sein. Hierdurch ist es möglich eine Anzahl unterschiedlicher Teile des Untergestells weiter zu vermindern und einen Zusammenbau des Untergestells zu vereinfachen. Die Kufen können j eweils achsensymmetrisch oder punktsymmetrisch ausgebildet sein, so dass eine Positionierung einer Kufe zu beispielsweise einem Mittelfuß oder einem Eckfuß beliebig ist. So können Kufen dann auch gleichartig ausgebildet sein, unabhängig davon, ob die j eweilige Kufe an einer bestimmten Seite des Untergestell s montiert ist. Alternativ können die Kufen auch unsymmetrisch ausgebildet sein. The runners can be designed symmetrically. This makes it possible to further reduce the number of different parts of the base frame and to simplify assembly of the base frame. The runners can be designed to be axially symmetrical or point symmetrical, so that the positioning of a runner in relation to a central foot or a corner foot is arbitrary. This means that runners can also be designed in the same way, regardless of whether the respective runner is mounted on a specific side of the base frame. Alternatively, the runners can also be designed asymmetrically.
Das Untergestell kann mit alleine zwei Außenkufen oder mit einer Mittelkufe und zwei Außenkufen ausgebildet sein. Die Mittelkufe und die zwei Außenkufen können relativ zueinander parallel angeordnet sein. Die Mittelkufe kann dann zwischenliegend den beiden Außenkufen angeordnet sein. Wenn die Kufen symmetrisch ausgebildet sind, können die beiden Außenkufen identisch ausgebildet sein. Hierdurch wird eine Herstellung des Untergestells vereinfacht. The underframe can be designed with just two outer runners or with one middle runner and two outer runners. The middle runner and the two outer runners can be arranged parallel to each other. The middle runner can then be arranged between the two outer runners. If the runners are designed symmetrically, the two outer runners can be designed identically. This simplifies the manufacture of the underframe.
Die Mittelkufe kann einen Zentralfuß des Untergestells ausbilden. Der Zentralfuß kann beispielsweise dadurch ausgebildet sein, dass der Zentralfuß in die Mittelkufe eingeprägt ist. Die Mittelkufe kann dann in ihrer Mitte mit einem bogen- oder dachförmigen Zentralfuß ausgebildet sein. Beispielsweise kann der Zentralfuß durch zwei Schenkel ausgebildet sein, die abweichend von einer Längserstreckung der Mittelkufe ausgebildet sind und so eine U- oder V-förmige Erhebung der Mittelkufe ausbilden. Zwei gegenüberliegende Mittelfüße können über eine Bodentraverse miteinander verbunden sein oder die Bodentraverse kann die zwei gegenüberliegenden Mittelfüße ausbilden. Die Bodentraverse kann in Art einer Kufe als einstückiger Tiefziehkörper aus Metallblech ausgebildet sein und Versteifungssicken aufweisen. Die Bodentraverse kann so ausgebildet sein, dass sie zwei gegenüberliegende Mittelfüße, die ihrerseits als einstückige Tiefziehkörper aus Metallblech ausgebildet sind, verbindet. Die Bodentraverse ist dann vergleichsweise flach ausgebildet. Alternativ kann die Bodentraverse die zwei gegenüberliegenden Mittelfüße ausbilden, dadurch, dass die Bodentraverse an ihren j eweiligen Längsenden Mittelfußkörper aufweist, die ihrerseits einen U-förmigen oder V- förmigen Querschnitt relativ bezogen auf eine Längsachse der Mittelkufe aufweisen. Der j eweilige Mittelfuß kann dann mit einer Basiswand, einer äußeren Schenkelwand und einer inneren Schenkelwand ausgebildet sein. Die Basiswand und die Schenkelwände können an axialen Endbereichen des Mittelfußes in einer Ebene quer zu einer Längsachse des Mittelfußes ausgebildet sein und einen U-förmigen Randsteg ausbilden. The middle skid can form a central foot of the underframe. The central foot can be formed, for example, by the central foot being embossed into the middle skid. The middle skid can then be formed with an arched or roof-shaped central foot in its middle. For example, the central foot can be formed by two legs that are formed differently from a longitudinal extension of the middle skid and thus form a U- or V-shaped elevation of the middle skid. Two opposing center feet can be connected to one another via a floor cross member, or the floor cross member can form the two opposing center feet. The floor cross member can be designed in the manner of a runner as a one-piece deep-drawn body made of sheet metal and have stiffening beads. The floor cross member can be designed such that it connects two opposing center feet, which in turn are designed as one-piece deep-drawn bodies made of sheet metal. The floor cross member is then comparatively flat. Alternatively, the floor cross member can form the two opposing center feet in that the floor cross member has center foot bodies at their respective longitudinal ends, which in turn have a U-shaped or V-shaped cross-section relative to a longitudinal axis of the center runner. The respective center foot can then be designed with a base wall, an outer leg wall, and an inner leg wall. The base wall and the leg walls can be formed at axial end regions of the metatarsal in a plane transverse to a longitudinal axis of the metatarsal and form a U-shaped edge web.
Ein Zentralfuß des Untergestells kann unmittelbar mit der Bodentraverse mittels einer lösbaren Verbindung verbunden sein. In der Bodentraverse kann eine napfartige Vertiefung ausgebildet sein, die sich in Richtung des Zentralfußes erstreckt. Hierdurch kann eine Gewichtskraft des Innenbehälters vorteilhaft über die Bodentraverse in den Mittelfuß eingeleitet werden. Die lösbare Verbindung kann beispielsweise eine Schraubverbindung sein. Die Schraubverbindung kann durch eine einzelne, zentrale Blechschraube einfach ausgebildet werden. A central foot of the base frame can be connected directly to the floor cross member by means of a detachable connection. A bowl-like depression can be formed in the floor cross member, which extends in the direction of the central foot. This allows a weight force of the inner container to be advantageously introduced into the central foot via the floor cross member. The detachable connection can be a screw connection, for example. The screw connection can be easily formed using a single, central sheet metal screw.
Somit ist es dann auch vorteilhaft, wenn zwischen dem Zentralfuß und der Bodentraverse eine formschlüssige Verdrehsicherung ausgebildet ist. Es kann dann verhindert werden, dass die mit der Bodentraverse ve- schraubte Mittelkufe sich relativ zur Bodentraverse bewegt bzw. verdreht. Eine Lage der Mittelkufe relativ zur Bodentraverse kann dann sicher fixiert werden, so dass die Mittelkufe mit der Bodentraverse vor- montiert werden kann. Die Verdrehsicherung kann beispielsweise durch in der Mittelkufe ausgebildete Laschen, die in Bohrungen der Bodentraverse eingreifen oder umgekehrt, kostengünstig ausgebildet werden. Die Laschen können durch Prägen und die Bohrungen durch Stanzen ausgebildet sein. Sofern die Mittelkufe und die Bodentraverse durch Tiefziehen hergestellt werden, können die Laschen bzw. die Bohrungen ohne einen weiteren Arbeitsgang bei dem Tiefziehen ausgebildet werden. It is therefore also advantageous if a positive locking device is formed between the central foot and the floor crossbeam. This can prevent the middle skid screwed to the floor crossbeam from moving or twisting relative to the floor crossbeam. The position of the middle skid relative to the floor crossbeam can then be securely fixed so that the middle skid is in contact with the floor crossbeam. can be mounted. The anti-twisting device can be created inexpensively, for example, by means of tabs formed in the middle skid that engage in holes in the base cross member or vice versa. The tabs can be created by embossing and the holes by punching. If the middle skid and the base cross member are made by deep drawing, the tabs or the holes can be created without any further work step during the deep drawing.
Die Mittelkufe kann mit einem Mittelfuß verschweißt und mit einem diesem gegenüberliegenden von dem Boden ausgebildeten napfförmigen Mittelfuß unmittelbar verschraubt sein. Das Verschweißen der Mittelkufe mit dem Mittelfuß kann beispielsweise mittels Widerstandsstumpfschweißen erfolgen. Der Mittelfuß kann dann an einem Ende der Mittelkufe fest fixiert sein, so dass die Mittelkufe zusammen mit dem Mittelfuß eine Baugruppe des Untergestells ausbildet. Wenn der Boden mit einem napfförmigen Mittelfuß ausgebildet ist, d. h. der Mittelfuß in den Boden eingeformt ist, kann bei einer Montage des Untergestells der Boden bzw. der darin ausgebildete Mittelfuß einfach mit der Mittelkufe verschraubt sein. The central runner can be welded to a central foot and directly screwed to a cup-shaped central foot formed by the floor opposite this. The central runner can be welded to the central foot using resistance butt welding, for example. The central foot can then be firmly fixed to one end of the central runner, so that the central runner and the central foot together form an assembly of the base frame. If the floor is formed with a cup-shaped central foot, i.e. the central foot is formed into the floor, the floor or the central foot formed in it can simply be screwed to the central runner when assembling the base frame.
Die Außenkufen können mit den Eckfüßen und/oder den Mittelfüßen verschweißt sein. Beispielsweise kann vorgesehen sein, die Außenkufen durch Widerstandsstumpfschweißen zu verschweißen. Die Außenkufen können mittels beispielsweise zwei, vorzugsweise vier Schweißpunkten mit den Eckfüßen verbunden sein. Die Eckfüße können so an den Außenkufen sicher und nicht mehr bewegbar angeordnet werden. Weiter können auch die Mittelfüße an den Außenkufen mittels zumindest zwei Schweißpunkten verschweißt sein. Wenn die Mittelfüße durch eine Bodentraverse ausgebildet werden, kann eine Bauteilgruppe aus Eckfüßen, Mittelfüßen und Außenkufen ausgebildet werden, die im Rahmen eines Herstellungsprozesses des Untergestells mit nur wenigen Arbeitsschritten ausgebildet und gehandhabt werden kann. Weiter können die Verbindungen des Bodens zu den Eckfüßen und den Mittelfüßen al s lösbare Verbindungen ausgeführt sein. Das Untergestell kann dann aus zwei bis drei Baugruppen ausgebildet sein, die in einem ab schließenden Montageschritt zu dem Untergestell zusammengeführt werden. Eine Baugruppe kann beispielsweise aus Außenkufen mit Eckfüßen, Mittelfüßen und einer Bodentraverse gebildet sein, eine weitere Baugruppe kann aus einer Mittelkufe mit einem Mittelfuß gebildet sein, und eine dritte Baugruppe aus dem Boden, wobei der Boden ebenfalls einen Mittelfuß ausbilden kann. Wenn die Verbindungen zwischen Eckfüßen, Mittelfüßen und Kufen durch Schweißen ausgebildet sind, können die Eckfüße und Mittelfüße in ihrer für eine Verbindung mit dem Boden vorgesehenen Lage genau positioniert bzw. fixiert werden. So ist es dann in einem abschließenden Montageschritt einfach möglich den Boden mit den Eckfüßen und den Mittelfüßen zu verschrauben. Diese Verschraubung kann auch derart erfolgen, dass ein Außenmantel eines Transport- und Lagerbehälters dabei gleichzeitig mit diesen Schrauben verschraubt wird. The outer runners can be welded to the corner feet and/or the center feet. For example, the outer runners can be welded by resistance butt welding. The outer runners can be connected to the corner feet using, for example, two, preferably four welding points. The corner feet can thus be securely attached to the outer runners so that they cannot move. The center feet can also be welded to the outer runners using at least two welding points. If the center feet are formed by a floor crossbeam, a component group consisting of corner feet, center feet and outer runners can be formed, which can be formed and handled in just a few work steps as part of a manufacturing process for the base frame. Furthermore, the connections of the floor to the corner feet and the center feet can be designed as detachable connections. The subframe can then be made up of two or three assemblies which are brought together to form the subframe in a final assembly step. One assembly can, for example, be made up of outer runners with corner feet, center feet and a floor cross member, another assembly can be made up of a center runner with a center foot, and a third assembly can be made up of the floor, whereby the floor can also form a center foot. If the connections between the corner feet, center feet and runners are made by welding, the corner feet and center feet can be precisely positioned or fixed in the position intended for connection to the floor. In this way, it is then easy to screw the floor to the corner feet and the center feet in a final assembly step. This screw connection can also be made in such a way that an outer shell of a transport and storage container is screwed together with these screws at the same time.
Die Kufen können die Eckfüße und/oder die Mittelfüße des Untergestells ausbilden. Dann ist es nicht mehr erforderlich die die Eckfüße und/oder die Mittelfüße mit den Kufen zu verbinden. Die Eckfüße und/oder die Mittelfüße können beispielsweise dadurch ausgebildet sein, dass die Eckfüße und/oder die Mittelfüße in Außenkufen eingeprägt sind. Die j eweilige Kufe kann dann in ihrer Mitte mit einem bogen- oder dachförmigen Mittelfuß ausgebildet sein. Beispiel sweise können die Eckfuße j eweils durch zwei Schenkel ausgebildet sein, die abweichend von einer Längserstreckung der Kufe ausgebildet sind und so eine U- oder V- förmige Erhebung der Kufe ausbilden. The runners can form the corner feet and/or the middle feet of the base frame. Then it is no longer necessary to connect the corner feet and/or the middle feet to the runners. The corner feet and/or the middle feet can be formed, for example, by the corner feet and/or the middle feet being embossed into outer runners. The respective runner can then be formed with an arched or roof-shaped middle foot in its middle. For example, the corner feet can each be formed by two legs that are formed deviating from a longitudinal extension of the runner and thus form a U- or V-shaped elevation of the runner.
Außenkanten der Aufstandsfläche der Kufen können derart ausgebildet sein, dass die Außenkanten zumindest ab schnittsweise von den Eckfüßen seitlich überragt werden und das Untergestell mit den Außenkanten innerhalb einer Innenkante eines oberen Rahmenprofils des Außenmantels des Transport- und Lagerbehälters eingesetzt werden kann. Das Untergestell ist dann so ausgebildet, dass ein mit dem Untergestell versehener Transport- und Lagerbehälter mit weiteren im Wesentlichen gleichartigen Transport- und Lagerbehältern gestapelt werden kann. Die Kufen können dabei so ausgebildet sein, dass ein oberer Transport- und Lagerbehälter auf einem unteren Transport- und Lagerbehälter bzw. das Untergestell des oberen Transport- und Lagerbehälters auf einem oberen Rahmenprofil des unteren Transport- und Lagerbehälters zentriert wird. Dadurch, dass die Kufen dann zumindest abschnittsweise innerhalb der Innenkante des oberen Rahmenprofils einsetzbar sind, kann eine horizontale Bewegung des oberen Transport- und Lagerbehälters auf dem unteren Transport- und Lagerbehälter im Wesentlichen verhindert werden. Die Kufen fügen sich demnach so innerhalb der Innenkanten mit ihren Außenkanten ein, dass in einer horizontalen Richtung ein Formschluss erzielt werden kann. Outer edges of the contact surface of the runners can be designed in such a way that the outer edges are at least partially overhanged by the corner feet and the undercarriage with the outer edges is within an inner edge of an upper frame profile of the outer casing of the transport and storage container. The underframe is then designed in such a way that a transport and storage container provided with the underframe can be stacked with other essentially similar transport and storage containers. The runners can be designed in such a way that an upper transport and storage container is centered on a lower transport and storage container or the underframe of the upper transport and storage container is centered on an upper frame profile of the lower transport and storage container. Because the runners can then be used at least in sections within the inner edge of the upper frame profile, horizontal movement of the upper transport and storage container on the lower transport and storage container can be essentially prevented. The runners therefore fit within the inner edges with their outer edges in such a way that a positive connection can be achieved in a horizontal direction.
Der erfindungsgemäße Transport- und Lagerbehälter für Flüssigkeiten ist mit einem Innenbehälter aus Kunststoff mit vier Seitenwänden, einem unteren und einem oberen Boden, einem am oberen Boden angeformten, verschließbaren Einfüllstutzen und einem am unteren Abschnitt einer Seitenwand angeformten Auslaufstutzen mit einer Entnahmearmatur sowie einem vorzugsweise als Gitter ausgeführten Außenmantel aus Metall zur Aufnahme des Innenbehälters sowie einem erfindungsgemäßen palettenartigen Untergestell ausgebildet.

Eine Zusammenschau der Fig. 1 bis 14 zeigt einen Transport- und Lagerbehälter 10 für Flüssigkeiten mit einem palettenartigen Untergestell 1 1. Der Transport- und Lagerbehälter 10 ist mit einem Innenbehälter 12 aus Kunststoff mit vier Seitenwänden 13 , 14, 15, 16, einem unteren Boden 17 und einem oberen Boden 18, einem am oberen Boden 18 angeformten, verschließbaren Einfüllstutzen 19 und einem am unteren Abschnitt einer Seitenwand 13 angeformten Auslaufstutzen 20 mit einer Entnahmearma- tur 21 sowie einem als Gitter 22 ausgeführten Außenmantel 23 aus Metall zur Aufnahme des Innenbehälters 12 sowie dem palettenartigen Untergestell 1 1 ausgebildet. Der Außenmantel 23 ist mit einem oberen Rahmenprofil 24 und einem unteren Rahmenprofil 25 ausgebildet, welches mit dem palettenartigen Untergestell 1 1 verschraubt ist. A summary of Figs. 1 to 14 shows a transport and storage container 10 for liquids with a pallet-like base frame 11. The transport and storage container 10 is provided with an inner container 12 made of plastic with four side walls 13, 14, 15, 16, a lower base 17 and an upper base 18, a closable filler neck 19 formed on the upper base 18 and an outlet neck 20 formed on the lower section of a side wall 13 with a removal arm. ture 21 and an outer casing 23 made of metal in the form of a grid 22 for receiving the inner container 12 and the pallet-like base frame 1 1. The outer casing 23 is formed with an upper frame profile 24 and a lower frame profile 25, which is screwed to the pallet-like base frame 1 1.
Die Fig. 3 zeigt eine Unteransicht des Untergestells 1 1 , welches aus einem Boden 26 zur Abstützung des in dem Außenmantel 23 aufgenommenen Innenbehälters 12 dient, und aus Eckfüßen 27, Mittelfüßen 28, 29, 30, einem Zentralfuß 3 1 , zwei Außenkufen 32, einer Mittelkufe 33 und einer Bodentraverse 34 gebildet ist. Das Untergestell 1 1 ist hier vollständig aus Metall ausgebildet. Die Fig. 2 zeigt eine Montagebaugruppe 35, welche nicht den Boden 26 aufweist. Fig. 3 shows a bottom view of the base frame 11, which is made up of a base 26 for supporting the inner container 12 accommodated in the outer casing 23, and of corner feet 27, middle feet 28, 29, 30, a central foot 31, two outer skids 32, a middle skid 33 and a base cross member 34. The base frame 11 is made entirely of metal here. Fig. 2 shows an assembly unit 35, which does not have the base 26.
Eine Zusammenschau der Fig- 4 und 8 zeigt eine der Außenkufen 32 die mit Versteifungssicken 36 mit Stegen 27 ausgebildet ist. Die Stege 37 verlaufen zwischen Obergurten 38 und Untergurten 39 der Versteifungssicken 36. Die Untergurte 39 bilden dabei j eweils eine Aufstandsfläche 40 des Untergestells 1 1 aus, die üblicherweise auf einem hier nicht dargestellten Untergrund zur Anlage gelangt. Weiter ist die Außenkufe 32 ab schnittsweise mit einem Randsteg 41 ausgebildet. Eine Höhe der Außenkufe 32 über der Aufstandsfläche 40 ist in einem Abschnitt 42 vermindert. In dem Abschnitt 42 ist weiter der Randsteg 41 unterbrochen ausgebildet. Der Ab schnitt 42 bildet so eine Überfahrschwelle 43 für z. B . einen Hubwagen aus. Weiter sind in der Außenkufe 32 Schweißbuckel 44 und 45 zur Ausbildung einer Schweißverbindung mit den Eckfüßen 27 bzw. den Mittelfüßen 28 ausgebildet. A combination of Figures 4 and 8 shows one of the outer skids 32 which is designed with stiffening beads 36 with webs 27. The webs 37 run between upper chords 38 and lower chords 39 of the stiffening beads 36. The lower chords 39 each form a contact surface 40 of the underframe 11, which usually comes to rest on a surface not shown here. Furthermore, the outer skid 32 is designed in sections with an edge web 41. A height of the outer skid 32 above the contact surface 40 is reduced in a section 42. In section 42, the edge web 41 is also interrupted. Section 42 thus forms a threshold 43 for a forklift truck, for example. Furthermore, welding bosses 44 and 45 are formed in the outer runner 32 to form a welded connection with the corner feet 27 and the center feet 28, respectively.
Eine Zusammenschau der Fig- 5, 6 und 7 zeigt die Mittelkufe 33 , die ebenfalls mit Versteifungssicken 46 ausgebildet ist. Auch hier verlaufen Stege 47 zwischen Obergurten 48 und Untergurten 49, die ihrerseits die Aufstandsfläche 40 des Untergestells 1 1 ausbilden. In einem Abschnitt 50 ist eine Höhe der Mittelkufe 33 gegenüber der Aufstandsfläche 40 vermindert ausgebildet, so dass eine Überfahrschwelle 51 ausgebildet ist. Weiter weist die Mittelkufe 33 Schweißbuckel 52 auf, die zum Verschweißen der Mittelkufe 33 mit dem Mittelfuß 29 dienen. Die Mittelkufe 33 bildet darüber hinaus den U-förmigen Zentralfuß 3 1 aus. Der Zentralfuß 3 1 ist durch zwei Schenkel 53 der Mittelkufe 33 ausgebildet, die sich zu einem horizontalen Abschnitt 54 hin erstrecken. In dem horizontalen Ab schnitt 54 bzw. den Obergurten 48 sind Laschen 55 und eine zentrale Durchgangsöffnung 56 ausgebildet. A summary of Figures 5, 6 and 7 shows the central skid 33, which is also designed with stiffening beads 46. Here too, webs 47 run between upper chords 48 and lower chords 49, which in turn form the contact surface 40 of the underframe 11. In a section 50, the height of the central skid 33 is reduced compared to the contact surface 40, so that a drive-over threshold 51 is formed. The central runner 33 also has welding bosses 52 which serve to weld the central runner 33 to the central foot 29. The central runner 33 also forms the U-shaped central foot 31. The central foot 31 is formed by two legs 53 of the central runner 33 which extend to a horizontal section 54. In the horizontal section 54 or the upper chords 48, tabs 55 and a central through-opening 56 are formed.
Die Fig. 9 zeigt den Eckfuß 27 mit der Außenkufe 32 in einer Montagekonfiguration mit an den Schweißbuckeln 44 ausgebildeten Schweißpunkten 57. Fig. 9 shows the corner foot 27 with the outer skid 32 in an assembly configuration with welding points 57 formed on the welding projections 44.
Die Fig. 10 zeigt die Außenkufe 32 mit einem Mittelfuß 28, der wie der gegenüberliegende Mittelfuß 28 von der Bodentraverse 34 einstückig ausgebildet ist. Hier sind Schweißbuckel 45 mit dem Mittelfuß 28 durch Schweißpunkte 58 verbunden. Fig. 10 shows the outer runner 32 with a center foot 28, which, like the opposite center foot 28, is formed in one piece from the floor cross member 34. Here, welding bosses 45 are connected to the center foot 28 by welding points 58.
Die Fig. 11 zeigt die Mittelkufe 33 in einer Montagekonfiguration mit dem Mittelfuß 29, der hier einstückig ausgebildet ist. Hier sind Schweißbuckel 52 der Mittelkufe 33 über Schweißpunkte 59 mit dem Mittelfuß 29 verbunden. Fig. 11 shows the center skid 33 in an assembly configuration with the center foot 29, which is formed in one piece here. Here, welding bosses 52 of the center skid 33 are connected to the center foot 29 via welding points 59.
Die Fig. 12 zeigt eine Montagekonfiguration der Mittelkufe 33 mit dem Boden 26, wobei der Boden 26 mit dem napfförmig in den Boden 26 eingeprägten Mittelfuß 30 ausgebildet ist. Hier ist zwischen der Mittelkufe 33 und dem Mittelfuß 30 eine Schraubverbindung 60 mit einer nicht näher dargestellten Schraube ausgebildet. Im Übrigen ist der Boden 26 auch mit den Eckfüßen 27 und den Mittelfüßen 28 und 29 verschraubt. Fig. 12 shows an assembly configuration of the central runner 33 with the base 26, wherein the base 26 is formed with the central foot 30 embossed in the shape of a cup into the base 26. Here, a screw connection 60 with a screw (not shown in detail) is formed between the central runner 33 and the central foot 30. The base 26 is also screwed to the corner feet 27 and the central feet 28 and 29.
Die Fig. 13 zeigt die Mittelkufe 33 in einer Querschnittansicht an dem horizontalen Ab schnitt 54 zusammen mit der Bodentraverse 34 in einer Montagekonfiguration. Die Bodentraverse 34 ist mit einem von dem Boden 26 abgewandten Bogen 61 ausgebildet. In der Bodentraverse 34 sind zwei Durchgangsöffnungen 62 ausgebildet, in die die Laschen 55 einge- setzt sind. Weiter ist durch die Durchgangsöffnung 56 der Mittelkufe 33 eine Schraube 63 in eine Tulpung 64 in einem Zentrum der Bodentraverse 34 eingeschraubt. Dadurch, dass die Laschen 55 in die Durchgangsöffnungen 62 eingesetzt sind, wird eine formschlüssige Verdrehsicherung 65 ausgebildet. Fig. 13 shows the central skid 33 in a cross-sectional view at the horizontal section 54 together with the floor cross member 34 in an assembly configuration. The floor cross member 34 is formed with a curve 61 facing away from the floor 26. Two through-openings 62 are formed in the floor cross member 34, into which the tabs 55 are inserted. Furthermore, a screw 63 is screwed through the through opening 56 of the central skid 33 into a tulip 64 in a center of the floor cross member 34. Because the tabs 55 are inserted into the through openings 62, a positive anti-twist device 65 is formed.
Die Fig. 14 zeigt in Teilen eine Schnittansicht einer Stapelanordnung 66 von Transport- und Lagerbehältern 10. Insbesondere sind hier Außenkanten 67 der Aufstandsfläche 40 so ausgebildet, dass diese innerhalb einer Innenkante 68 des oberen Rahmenprofils 24 eingesetzt ist. Das obere Rahmenprofil 24 bzw. dessen abgeflachte Oberseite 69 dient hier zurFig. 14 shows a partial sectional view of a stack arrangement 66 of transport and storage containers 10. In particular, outer edges 67 of the support surface 40 are designed such that it is inserted within an inner edge 68 of the upper frame profile 24. The upper frame profile 24 or its flattened upper side 69 serves here for
Auflage einer Unterseite 70 der Eckfüße 27 bzw. der Mittelfüße 28 und 29. Support of a bottom side 70 of the corner feet 27 or the middle feet 28 and 29.
