Description

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung einer im Boden versenkt angeordneten Hebeeinrichtung für Kraftfahrzeuge od. dgl.. Des weiteren betrifft die vorliegende Erfindung die Verwendung wenigstens einer Stahlkassette für die Aufnahme einer Hebeeinrichtung.The present invention relates to a method for producing a countersunk in the ground arranged lifting device for motor vehicles od. Like .. Further, the present invention relates to the use of at least one steel cassette for receiving a lifting device.

Hebeeinrichtungen der genannten Art dienen zum Anheben von Kraftfahrzeugen in Kraftfahrzeug-Werkstätten, Tankstellen oder in Forschungsbetrieben, die sich mit Kraftfahrzeugen beschäftigen. Vorzugsweise werden Hebeeinrichtungen dieser Art versenkt im Boden, insbesondere Hallenboden angeordnet derart, dass sie in abgesenkter Position ohne weiteres von einem Fahrzeug überfahren werden können. Damit kann das Fahrzeug über der Hebeeinrichtung positioniert und durch die Hebeeinrichtung auf eine gewünschte Höhe angehoben werden. Beim Betrieb solcher Hebeeinrichtungen sind lediglich die Hubstangen bzw. Hubzylinder oberhalb des jeweiligen Bodens vorhanden, so dass ein maximal großer Freiraum zwischen dem angehobenen Kraftfahrzeug und dem Boden vorhanden ist. Eine derartige Hebeeinrichtung wird in der US 5,860,491 beschrieben.Lifting devices of the type mentioned are used for lifting motor vehicles in motor vehicle workshops, gas stations or in research companies that deal with motor vehicles. Preferably, lifting devices of this type are sunk in the ground, in particular hall floor arranged such that they can be easily run over by a vehicle in the lowered position. Thus, the vehicle can be positioned over the lifting device and lifted by the lifting device to a desired height. In the operation of such lifting devices, only the lifting rods or lifting cylinders are present above the respective floor, so that a maximum of large space between the raised motor vehicle and the ground is present. Such a lifting device is in the US 5,860,491 described.

Es ist auch bekannt, Hebeeinrichtungen der genannten Art innerhalb von quaderartigen Kassetten, insbesondere Stahlkassetten anzuordnen. Die Kassetten dienen zur Aufnahme der eigentlichen Hubaggregate, insbesondere der Hydraulik und/oder Elektromotorik. Die Kassetten sind beim Stand der Technik innerhalb vorgefertigter Betonschächte versenkt angeordnet. Der Aufwand dafür ist relativ hoch.It is also known to arrange lifting devices of the type mentioned within cuboidal cassettes, in particular steel cassettes. The cassettes are used to hold the actual lifting units, in particular the hydraulics and / or electromotive. The cassettes are arranged sunk in the prior art within prefabricated concrete shafts. The effort is relatively high.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren anzugeben, das hinsichtlich der Herstellung einer im Boden versenkt angeordneten Hebeeinrichtung erheblich einfacher ist, ohne dass die Funktionsfähigkeit darunter leidet. Des weiteren ist es Aufgabe, Aufnahmekassetten zur Verfügung zu stellen, die sich besonders leicht für den angegebenen Zweck handhaben lassen.The present invention is therefore based on the object of specifying a method which is considerably simpler in terms of the production of a sunk in the ground arranged lifting device without the functionality suffers. Furthermore, it is an object to provide recording cassettes that can be handled particularly easily for the stated purpose.

Hinsichtlich des Verfahrens wird die gestellte Aufgabe durch die Verfahrensschritte gemäß Anspruch 1 gelöst, wobei die Unteransprüche bevorzugte Details des erfindungsgemäßen Verfahrens angeben.With regard to the method, the stated object is achieved by the method steps according to claim 1, wherein the dependent claims indicate preferred details of the method according to the invention.

Das erfindungsgemäße Verfahren weist demnach folgende Verfahrensschritte auf:

  • Ausheben einer Bodenausnehmung bzw. Grube;
  • Errichten eines Bodenfundaments, vorzugsweise aus Beton;
  • Aufsetzen einer vorgefertigten Kassette, insbesondere Stahlkassette, zur Aufnahme einer Hebeeinrichtung auf das Bodenfundament;
  • Ausrichten der Kassette auf dem Bodenfundament, so dass die Kassette auf dem Bodenfundament aufrecht steht und der obere Rand der Kassette letztlich bündig mit einem Hallenboden od. dgl. abschließt;
  • Auffüllen der Grube mit verdichtungsfähigem Material, insbesondere bestehend aus Erdreich und Schotter, bis zu einer vorbestimmten "Installationshöhe";
  • Ausbilden einer Beton- oder Mörtelschicht auf dem Niveau der vorbestimmten Installationshöhe, wodurch die Grubenfüllung stabilisiert wird;
  • Anschluß von Installationsleitungen an wenigstens einer Seitenwand der Kassette und durch diese hindurch, und zwar oberhalb oder dauerhaft fixiert durch die vorgenannte Beton- oder Mörtelschicht;
  • Auffüllen der Grube mit verdichtungsfähigem Material, insbesondere bestehend aus Erdreich und Schotter, bis auf ein Niveau "Unterseite Arbeits- oder Hallenboden"; und
  • Errichten einer einen Arbeits- oder Hallenboden bildenden Betonschicht bis zum oberen Rand der Kassette.
The process according to the invention accordingly has the following process steps:
  • Excavating a floor recess or pit;
  • Building a foundation, preferably made of concrete;
  • Placing a prefabricated cassette, in particular a steel cassette, for receiving a lifting device on the base foundation;
  • Aligning the cassette on the bottom foundation, so that the cassette stands upright on the ground foundation and the upper edge of the cassette is ultimately flush with a hall floor or the like;
  • Filling the pit with compressible material, in particular consisting of earth and gravel, up to a predetermined "installation height";
  • Forming a concrete or mortar layer at the level of the predetermined installation height, thereby stabilizing the pit filling;
  • Connecting installation leads to and through at least one side wall of the cassette, above or permanently fixed by the aforesaid concrete or mortar layer;
  • Filling the pit with compressible material, in particular consisting of soil and gravel, up to a level "bottom work or hall floor"; and
  • Erection of a concrete layer forming a working or hall floor up to the upper edge of the cassette.

Die Grube zur Aufnahme der vorstehend genannten Kassette weist vorzugsweise die Form eines umgekehrten Pyramidenstumpfes auf. D.h. die Seitenwände der Grube sind vom Boden ausgehend in Richtung nach oben schräg nach außen geneigt. Damit ist eine seitliche Abstützung der Gruben-Seitenwände entbehrlich. Insbesondere sind keine Schalbretter für Betonstützwände erforderlich.The pit for receiving the above-mentioned cassette preferably has the shape of a reverse truncated pyramid. That The side walls of the pit are inclined from the ground in the upward direction obliquely outward. Thus, a lateral support of the pit sidewalls is unnecessary. In particular, no sheathing boards for concrete supporting walls are required.

Erfindungsgemäß ist es denkbar, in einer Grube zwei oder mehr Kassetten in vorbestimmtem Abstand und in vorbestimmter Zuordnung zueinander zu plazieren. Die Einbettung innerhalb der Grube erfolgt dann für alle Kassetten gleichermaßen bzw. gleichzeitig. Die Herstellungskosten sind dann für eine Gruppe von Kassetten bzw. entsprechenden Hebeeinrichtungen entsprechend niedrig. Es ist denkbar, bis zu 100 und mehr Hebeeinrichtungen in einem gemeinsamen Arbeitsgang im Boden zu verfestigen.According to the invention, it is conceivable to place two or more cassettes in a pit at a predetermined distance and in a predetermined association with each other. The embedding within the pit then takes place for all cassettes alike or simultaneously. The manufacturing costs are then correspondingly low for a group of cassettes or corresponding lifting devices. It is conceivable to consolidate up to 100 and more lifting devices in a common operation in the ground.

Sofern der Boden um die Hebeeinrichtung herum aus Beton hergestellt sein soll, wird am oberen Rand bzw. Kopf jeder Kassette vor der Errichtung des aus Beton bestehenden Bodens eine Stahlarmierung angeschlossen.If the floor around the lifting device is to be made of concrete, a steel reinforcement is connected to the top of each cassette prior to the erection of the concrete floor.

Wie bereits erwähnt, eignet sich das erfindungsgemäße Verfahren insbesondere zum Verbau von Stahlkassetten, vorzugsweise doppelwandigen Stahlkassetten, die an sich bekannt sind.As already mentioned, the method according to the invention is particularly suitable for the installation of steel cassettes, preferably double-walled steel cassettes, which are known per se.

Um die Justierung der Kassetten innerhalb der Baugrube zu erleichtern, sind die Kassetten mit höhenverstellbaren Stützfüßen versehen. Mittels dieser höhenverstellbaren Stützfüße lassen sich die Kassetten auf dem Betonfundament relativ einfach justieren, d.h. sowohl auf Lot bringen und auch auf Höhe nivellieren.In order to facilitate the adjustment of the cassettes within the pit, the cassettes are provided with height-adjustable support feet. By means of these height-adjustable support feet, the cassettes on the concrete foundation can be adjusted relatively easily, i. both bring to Lot and also level on height.

Nachstehend wird anhand der Figuren 1 bis 6 ein Ausführungsbeispiel für ein erfindungsgemäßes Verfahren näher dargestellt.The following is based on the FIGS. 1 to 6 an embodiment of a method according to the invention shown in more detail.

Fig. 7 zeigt eine Ausführungsform mit mehreren Hebeeinrichtungen nebeneinander angeordnet. Fig. 7 shows an embodiment with a plurality of lifting devices arranged side by side.

Sämtliche Abbildungen zeigen das Verfahren im schematischen Längsschnitt sowohl der Baugrube als auch der in dieser positionierten Hebeeinrichtung,All figures show the method in a schematic longitudinal section of both the excavation and the lifting device positioned in this,

In Fig. 1 ist der erste Verfahrensschritt zur Herstellung einer im Boden versenkt angeordneten Hebeeinrichtung für Kraftfahrzeuge od. dgl. dargestellt, nämlich der Aushub des Bodens unter Herstellung einer Bodenausnehmung bzw. Grube 10. Diese Grube weist z.B. eine Tiefe von 2,70 m auf. Die Seitenwände der Grube sind schräg nach außen geneigt, so dass eine seitliche Abstützung der Seitenwände nicht erforderlich ist.In Fig. 1 is the first step for producing a sunk in the ground arranged lifting device for motor vehicles od. Like., Namely the excavation of the soil to produce a bottom recess or pit 10. This pit has, for example, a depth of 2.70 m. The side walls of the pit are inclined obliquely outwards, so that a lateral support of the side walls is not required.

Es folgt dann die Errichtung eines Bodenfundaments entsprechend Fig. 2. Dieses Bodenfundament ist mit der Bezugsziffer 11 gekennzeichnet.It then follows the establishment of a foundation soil accordingly Fig. 2 , This ground foundation is identified by the reference numeral 11.

Auf diesem Fundament wird dann entsprechend Fig. 3 eine vorgefertigte Kassette, insbesondere Stahlkassette zur Aufnahme einer Hebeeinrichtung aufgesetzt bzw. positioniert. Diese Stahlkassette ist mit der Bezugsziffer 12 gekennzeichnet. Sie steht über Stützfüße 13 auf dem Betonfundament 11, wobei im vorliegenden Fall die Stützfüße 13 über Metalldübel am Betonfundament befestigt sind. Damit ist zum einen ein Potentialausgleich zwischen Stahlkassette und Betonfundament bzw. Erdreich hergestellt. Des Weiteren wird durch die beschriebene Anbindung der Kassette 12 am Betonfundament 11 verhindert, dass bei Eintritt von Beton zwischen Unterkante Kassette und Betonfundament die Kassette 12 nach oben "schwimmt" bzw. durch den Beton nach oben gedrängt wird. Dabei ist zu bedenken, dass der Raum zwischen Unterkante bzw. Boden der Kassette und Betonfundament vorzugsweise mit Beton ausgefüllt ist. Bei einer doppelwandigen Kassette gelangt der Beton in diesen unteren Bereich durch den Spaltraum zwischen seitlicher Innen- und seitlicher Außenwand der Kassette. Der Boden jeder Kassette erstreckt sich nur zwischen den seitlichen Innenwänden derselben. Der Spalt zwischen Innen- und Außenwand ist nach unten offen. Damit gelangt der Beton beim Ausfüllen dieses Spaltes in den Bereich unterhalb des Kassettenbodens. Für die beschriebene Betonverfüllung gibt es zwei Verfahrensausführungen, die weiter unten noch näher beschrieben werden.On this foundation then becomes appropriate Fig. 3 a prefabricated cassette, in particular steel cassette for receiving a lifting device placed or positioned. This steel cassette is identified by the reference numeral 12. It stands on support legs 13 on the concrete foundation 11, wherein in the present case, the support legs 13 are fastened via metal dowels on the concrete foundation. On the one hand, an equipotential bonding between the steel cassette and the concrete foundation or soil is produced. Furthermore, it is prevented by the described connection of the cassette 12 on the concrete foundation 11 that upon entry of concrete between the lower edge of the cassette and concrete foundation, the cassette 12 "floats" upwards or is pushed upwards by the concrete. It should be remembered that the space between the lower edge or bottom of the cassette and concrete foundation is preferably filled with concrete. In a double-walled cassette, the concrete passes into this lower area through the gap between the lateral inner and outer side wall of the cassette. The bottom of each cassette extends only between the lateral inner walls thereof. The gap between inner and outer wall is open at the bottom. Thus, the concrete passes in filling this gap in the area below the bottom of the cassette. For the concrete filling described, there are two process versions, which are described in more detail below.

Der Verfahrensschritt der Fixierung der Kassette am Betonfundament ist in Fig. 3 angedeutet. Vorzugsweise weist die Stahlkassette 12 an ihren vier Ecken höhenverstellbare Stützen auf, so dass die Stahlkassette auf dem Betonfundament 11 ausgerichtet und auch höhennivelliert werden kann. Die Höhenjustierung erfolgt so, dass der obere Rand 14 der Kassette 12 etwa bündig mit der Oberfläche des späteren Werkstatt- oder Hallenbodens abschließt. Das entsprechende Niveau ist in den anliegenden Figuren mit der Bezugsziffer 15 gekennzeichnet.The process step of fixing the cassette to the concrete foundation is in Fig. 3 indicated. The steel cassette 12 preferably has height-adjustable supports at its four corners, so that the steel cassette can be aligned on the concrete foundation 11 and can also be level-adjusted. The height adjustment is carried out so that the upper edge 14 of the cassette 12 is approximately flush with the surface of the later workshop or hall floor. The corresponding level is indicated by the reference numeral 15 in the accompanying figures.

Anschließend erfolgt entsprechend Fig. 4 ein Auffüllen der Grube 10 mit verdichtungsfähigem Material, insbesondere bestehend aus Erdreich und Schotter, bis zu einer Höhe unterhalb wenigstens eines seitlich an der Kassette 12 angeordneten Installationsrohres 16, durch das hindurch von außen her hydraulische und/oder elektrische Leitungen in das Kassetteninnere hinein verlegbar sind. Bei der dargestellten Ausführungsform sind an zwei gegenüberliegenden Seiten der Kassetten derartige Installationsrohre 16 angesetzt. Das Füllmaterial ist in Fig. 4 mit der Bezugsziffer 17 gekennzeichnet.Then follows accordingly Fig. 4 a filling of the pit 10 with compressible material, in particular consisting of soil and gravel, up to a level below at least one laterally arranged on the cartridge 12 installation tube 16 through which hydraulic and / or electrical lines from the outside are in the cassette inside laid , In the illustrated embodiment, such installation tubes 16 are attached to two opposite sides of the cassettes. The filling material is in Fig. 4 denoted by the reference numeral 17.

Danach erfolgt entsprechend Fig. 5 eine Stabilisierung des verdichtbaren Füllmaterials 17, welches im Übrigen schichtweise in die Grube eingefüllt und verdichtet wird, und zwar mittels einer Beton- oder Mörtelschicht 18 zwischen der Oberseite der Grubenfüllung 17 und der Unterkante des wenigstens einen Installationsrohres 16. Dann wird an das oder die Installationsrohre 16 noch ein Mantelrohr angesetzt, und zwar nach oben aus der Grube herausragend. Über dieses Mantelrohr 19 bleibt das Innere der Kassette von außen her für hydraulische und/oder elektrische Leitungen zugänglich. Es wird diesbezüglich auf Fig. 6 verwiesen.After that takes place accordingly Fig. 5 a stabilization of the compressible filling material 17, which is also filled in layers in the pit and compacted, by means of a concrete or mortar layer 18 between the top of the pit filling 17 and the lower edge of the at least one installation tube 16. Then, the or the installation tubes 16 still attached a jacket tube, and upstanding out of the pit. About this jacket tube 19, the interior of the cassette remains accessible from the outside for hydraulic and / or electrical lines. It gets up in this regard Fig. 6 directed.

Anschließend wird die Grube 10 mit verdichtungsfähigem Material vollständig aufgefüllt, und zwar bis auf Niveau "Unterseite Werkstatt- oder Hallenboden". Ein solcher Hallenboden wird dann errichtet, und zwar durch eine entsprechende Betonschicht 20.Subsequently, the pit 10 is completely filled with compaction-capable material, up to the level "bottom workshop or hall floor". Such a hall floor is then erected, through a corresponding concrete layer 20.

Bei Ausbildung des Hallenbodens aus Beton wird am oberen Rand 14 der Kassette 12 vor Errichtung des aus Beton bestehenden Bodens eine Stahlarmierung 21 angeschlossen. Durch diese wird die Tragfestigkeit des Werkstatt- bzw. Hallenbodens 20 in an sich bekannter Weise erhöht.When forming the hall floor made of concrete, a steel reinforcement 21 is connected to the upper edge 14 of the cassette 12 prior to the construction of the existing concrete floor. Through this, the bearing strength of the workshop or hall floor 20 is increased in a conventional manner.

Wie schon einleitend erwähnt, wird zur Aufnahme einer Hebeeinrichtung, d.h. der hydraulischen oder elektrohydraulischen oder elektromechanischen Hubaggregate eine Stahlkassette, insbesondere doppelwandige Stahlkassette verwendet, wobei der Zwischenraum zwischen Innen- und Außenwand der Stahlkassette mit Isoliermaterial oder Leichtbeton ausgefüllt sein kann. Es ist jedoch auch die Beibehaltung eines Hohlraums denkbar, in dem Leitungen verlegt sind. All dies kann herstellerseitig vorbereitet werden.As already mentioned in the introduction, a steel cassette, in particular double-walled steel cassette is used to accommodate a lifting device, ie the hydraulic or electro-hydraulic or electro-mechanical Hubaggregate, wherein the gap between the inner and outer wall of the steel cassette may be filled with insulating or lightweight concrete. However, it is also conceivable to maintain a cavity in which cables are laid. All this can be prepared by the manufacturer.

Des weiteren ist von Vorteil, wenn eine Kassette, insbesondere Stahlkassette verwendet wird, die mittels höhenverstellbarer Stützen auf dem Betonfundament 11 justierbar ist.Furthermore, it is advantageous if a cassette, in particular steel cassette is used, which is adjustable by means of height-adjustable supports on the concrete foundation 11.

In Fig. 7 ist eine Anordnung von mehreren, nämlich fünf Stahlkassetten jeweils zur Aufnahme einer Hebeeinrichtung innerhalb einer Grube 10 auf einem entsprechend groß bemessenen Betonfundament 11 dargestellt. Wie schon oben erwähnt, können statt einer mehrere, d.h. zwei und mehr Stahlkassetten mit entsprechenden Hebeeinrichtungen im Abstand voneinander und in vorbestimmtem Muster zueinander innerhalb einer entsprechend groß bemessenen Grube positioniert werden. Die Fixierung der Stahlkassetten erfolgt dann in gleicher Weise wie vorstehend anhand der Figuren 1 bis 6 beschrieben, wobei all dies gleichzeitig geschieht. Insofern ist die im Boden versenkte Anordnung von mehreren nebeneinander angeordneten Hebeeinrichtungen äußerst einfach und auch schnell durchführbar.In Fig. 7 an arrangement of several, namely five steel cassettes each for receiving a lifting device within a pit 10 on a correspondingly sized concrete foundation 11 is shown. As mentioned above, instead of a plurality, ie two and more steel cassettes with corresponding lifting devices at a distance from each other and in a predetermined pattern to each other within a correspondingly sized pit are positioned. The fixing of the steel cassettes is then in the same manner as above with reference to FIGS. 1 to 6 described, all of which happens simultaneously. In this respect, the sunken in the ground arrangement of several juxtaposed lifting devices is extremely simple and quick to carry out.

In Fig. 7 ist des Weiteren gut erkennbar die vorstehend erwähnte Stahlarmierung 21 für den Hallenboden, der in der Regel aus Beton hergestellt ist.In Fig. 7 Furthermore, it is well recognized the above-mentioned steel reinforcement 21 for the hall floor, which is usually made of concrete.

Bei Ausführung der Kassetten zur Aufnahme der Hebeeinrichtungen aus Stahl versteht es sich natürlich von selbst, dass es sich um rostfreien Stahl handelt oder um oberflächenverzinkten Stahl, der sich durch hohe Korrosionsbeständigkeit im Erdreich auszeichnet.When executing the cassettes for receiving the lifting devices made of steel, it goes without saying that it is stainless steel or surface galvanized steel, which is characterized by high corrosion resistance in the soil.

Bei Verwendung doppelwandiger Kassetten zur Aufnahme wenigstens einer Hebeeinrichtung wird in der Regel auch der Spaltraum zwischen Innen- und Außenwand mit Beton, insbesondere Leichtbeton ausgefüllt. In diesem Fall bieten sich zwei grundsätzliche Herstellungsverfahren an:When using double-walled cassettes for receiving at least one lifting device, the gap between the inner and outer walls is usually filled with concrete, in particular lightweight concrete. In this case, two basic production methods are available:

1. Ausführung:1st embodiment:

Nach dem Einsetzen einer oder mehrerer Kassetten in einer Grube 10 werden diese in der oben beschriebenen Weise einnivelliert, und zwar mittels höhenverstellbarer Stützfüße. Anschließend wird die Grube mit verdichtungsfähigem Material, insbesondere bestehend aus Erdreich und Schotter, bis zu einer Höhe unterhalb der seitlich angeordneten Installationsrohre 16 angeschüttet und verdichtet. Dann wird an das oder die Instaifationsrohr(e) jeweils ein Mantelrohr angeschlossen und mittels Beton oder Mörtel fixiert. Danach kann wiederum mit verdichtungsfähigem Material der vorgenannten Art bis zu einer Höhe unterhalb einer Hallenbodendecke angeschüttet und verdichtet werden. Auf dieser verdichteten Oberfläche wird die gesamte Hallenbodenarmierung mit Anschluß am Kopfteil jeder Kassette angebracht. Die Armierung wird mit dem Kopfteil jeder Kassette kraftschlüssig verbunden. Danach kann der Hallenboden in Verbindung mit der doppelwandigen Stahlkassette in einem einzigen Arbeitsgang mit Beton vergossen werden. Der Beton zwischen Hallenboden und Kassette muss nicht zwangsläufig über die gleiche Qualität verfügen. Die Kassette muss jedoch zumindest mit Beton der Qualität C20/25 F5-6 verfüllt werden.After inserting one or more cassettes in a pit 10 they are leveled in the manner described above, by means of height-adjustable support feet. Subsequently, the pit is compacted with compactable material, in particular consisting of soil and gravel, up to a level below the laterally arranged installation pipes 16 and compacted. Then, a jacket pipe is connected to the one or more Instaifationsrohr (s) and fixed by means of concrete or mortar. Thereafter, in turn, with compactable material of the aforementioned type can be poured up to a height below an indoor floor ceiling and be compacted. On this compacted surface, the entire hall floor reinforcement is attached to the top of each cassette. The reinforcement is frictionally connected to the head part of each cassette. Then the hall floor in conjunction with the double-walled steel cassette can be cast in a single operation with concrete. The concrete between the hall floor and the cassette does not necessarily have the same quality. However, the cassette must at least be filled with concrete of the quality C20 / 25 F5-6.

2. Ausführung:2nd version:

Die wenigstens eine Kassette zur Aufnahme wenigstens einer Hebeeinrichtung wird innerhalb der Grube 10 einnivelliert und am Betonfundament so befestigt, dass sie auch gegen Auftrieb nach oben gesichert ist. Unmittelbar danach wird der Zwischenraum zwischen Innen- und Außenwand der Kassette mit Beton zum Beispiel der Qualität C20/25 F5-6 bis Unterkannte Hallenboden vergossen. Hierbei ist darauf zu achten, dass der Freiraum zwischen Kassettenunterkante und Betonfundament mit Erdreich oder Beton ca. 15 bis 20 cm hoch um den Kassettenfuß herum angeschüttet ist, damit der in den Spaltraum zwischen Innenwand und Außenwand jeder Kassette eingefüllte Beton an der Unterseite der Kassette nicht seitlich nach Außen wegfließen kann.The at least one cassette for receiving at least one lifting device is leveled within the pit 10 and secured to the concrete foundation so that it is secured against buoyancy upwards. Immediately thereafter, the space between the inner and outer wall of the cassette with concrete, for example, the quality C20 / 25 F5-6 shed to unterkannte hall floor. It is important to ensure that the space between the lower edge of the cassette and the concrete foundation with soil or concrete is poured around 15 to 20 cm high around the cartridge foot, so that the filled in the gap between the inner wall and outer wall of each cassette concrete at the bottom of the cassette not can flow away laterally to the outside.

Der erwähnte Spalt zwischen der Unterseite jeder Kassette und der Oberfläche des Betonfundaments läßt sich nicht vermeiden, da das Betonfundament nicht immer maßhaltig und exakt horizontal sowie auf richtigem Niveau hergestellt werden kann. Daher wird jede Kassette bevorzugt über höhenverstellbare Stützen auf dem erwähnten Betonfundament 11 abgestellt und auf Lot und Höhe einnivelliert. Zu diesem Zweck ist der erwähnte untere Spalt erforderlich mit dem Nachteil, dass natürlich beim Einfüllen von Beton in den Zwischenraum zwischen seitlicher Innenwand und seitlicher Außenwand dann Beton auch durch den unteren Spalt zwischen Kassette und Betonfundament seitlich austreten kann. Dies gilt es zu verhindern.The mentioned gap between the bottom of each cassette and the surface of the concrete foundation can not be avoided, since the concrete foundation can not always be dimensionally accurate and exactly horizontal and at the right level can be produced. Therefore, each cassette is preferably parked on height-adjustable supports on the mentioned concrete foundation 11 and leveled to solder and height. For this purpose, the mentioned lower gap is required with the disadvantage that, of course, when pouring concrete in the space between the inner side wall and lateral outer wall then concrete can escape laterally through the lower gap between the cassette and concrete foundation. This must be prevented.

Das Anschütten der Grube 10 geschieht dann so wie oben im Zusammenhang mit der ersten Ausführung beschrieben.The pouring of the pit 10 then happens as described above in connection with the first embodiment.

Sämtliche in den Anmeldungsunterlagen offenbarten Merkmale werden als erfindungswesentlich beansprucht, soweit sie einzeln oder in Kombination gegenüber dem Stand der Technik neu sind.All disclosed in the application documents features are claimed as essential to the invention, as far as they are new individually or in combination over the prior art.
