At its rear end, the tube (2) is provided with a pot (7), the opening (8) of which is turned towards the point (3) and the diameter of which is larger than the diameter of the tube.

Description

Die Erfindung betrifft eine Vorrichtung zum Befestigen von stabförmigen Gegenständen, insbesondere Pfosten, im Erdreich, mit einem einen Kanal für den stabförmigen Gegenstand aufweisenden Rohr, das an seinem in Einschlagrichtung weisenden vorderen Ende mit einer Spitze versehen ist und im Bereich seines hinteren Endes konzentrisch von einem Ring in Gestalt eines umlaufenden Flacheisens mit einem größeren Durchmesser als dem Rohrdurchmesser umgeben ist.The invention relates to a device for fastening rod-shaped objects, in particular posts, in the ground, with a tube having a channel for the rod-shaped object, which is provided with a tip at its front end pointing in the direction of impact and concentrically from one in the region of its rear end Ring in the form of a circumferential flat iron with a larger diameter than the pipe diameter is surrounded.

Eine derartige Vorrichtung ist aus der GB-A-2 138 048 bekannt und verfügt über einen Ring, der die Peripherie mehrerer fachwerkartig angeordneter Stabilisierungsarme bildet. Die Stabilisierungsarme bestehen dabei aus Blechen oder Metallplatten, die in Ebenen angeordnet sind, welche parallel zur Längsachse des Rohres verlaufen. Die Stabilisierungsarme sind an ihren zum Rohr weisenden Enden mit einem Kragen verbunden, der es gestattet, die Stabilisierungsarmanordnung nach dem Einschlagen des Rohres auf das hintere Rohrende aufzuschieben.Such a device is known from GB-A-2 138 048 and has a ring which forms the periphery of a plurality of stabilizing arms arranged in the manner of a framework. The stabilizing arms consist of sheets or metal plates that are arranged in planes that run parallel to the longitudinal axis of the tube. The stabilizing arms are connected at their ends facing the tube with a collar, which allows the stabilizing arm arrangement to be pushed onto the rear tube end after the tube has been driven in.

In der LU-A-84 389 ist ebenfalls eine Vorrichtung der eingangs genannten Art beschrieben, bei der die Länge des innerhalb eines Ringmantels verlaufenden Rohres gleich oder kleiner als die Höhe des Ringmantels ist. Die Befestigung des Ringmantels am Rohr erfolgt mit mehreren radial ausgerichteten Blechen. Der durch den Ringmantel gebildete Hohlraum ist an den Stirnseiten offen und läßt sich zusammen mit dem gänzlich in ihm enthaltenen Rohr in den Boden schlagen, wobei jedoch eine Metalloder Holzplatte zum Abdecken der Öffnung des Ringmantels erforderlich ist, damit sich der Ringmantel mit Hilfe eines Hammers in den Boden einschlagen läßt. Da das vom Ringmantel umgebene Rohr nicht länger ist als die axiale Länge des Ringmantels, sind die erzielbaren Haltekräfte klein oder aber die Einschlagwege für den Ringmantel sehr groß wenn zur Erzielung höherer Auszugswerte eine große Baulänge vorgesehen wird.LU-A-84 389 also describes a device of the type mentioned at the outset, in which the length of the tube running within a ring jacket is equal to or less than the height of the ring jacket. The ring jacket is fastened to the tube with several radially aligned metal sheets. The cavity formed by the ring jacket is open at the end faces and can be knocked into the ground together with the pipe entirely contained in it, but a metal or wooden plate is required to cover the opening of the ring jacket so that the ring jacket can be hammered in with a hammer leaves the ground. Since the pipe surrounded by the ring jacket is no longer than the axial length of the ring jacket, the achievable holding forces are small or the impact distances for the ring jacket are very long if a large overall length is provided to achieve higher pull-out values.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, die schnell und einfach zu setzen ist und trotz einer guten Befestigung im Boden die natürlichen Bedingungen im Boden so wenig wie möglich stört.Based on this prior art, the invention has for its object to provide a device of the type mentioned, which is quick and easy to set and disturbs the natural conditions in the soil as little as possible despite good fastening in the ground.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der flacheisenförmige Ring mit dem Rohrende durch eine Scheibe befestigt ist, wobei der Ring die Wand und die Scheibe den Boden eines in Richtung auf das vordere Ende des Rohres geöffneten Topfes bilden.This object is achieved in that the flat iron ring is attached to the tube end by a disc, the ring, the wall and the disc form the bottom of a pot open towards the front end of the tube.

Dadurch, daß statt einzelner Stabilisierungsarme ein keine radiale Arme aufweisender umgestülpter Topf zum Stabilisieren des oberen Endes des Rohres dient, ergibt sich eine besonders einfache Handhabung sowie eine günstige Verankerung im Boden. Um den Wurzelwuchs so wenig wie möglich zu stören, können am Boden und an den Wänden des Topfes Durchbrüche vorgesehen sein. Durch diese können Pflanzen hindurchwachsen und dabei eine zusätzliche Befestigung und Verankerung bewirken. Außerdem verringern die am Boden des Topfes vorgesehenen Durchbrüche den Eindringwiderstand beim Einschlagen des Topfes in den oberen Bodenbereich.The fact that, instead of individual stabilizing arms, an upturned pot which has no radial arms serves to stabilize the upper end of the tube, this results in particularly simple handling and favorable anchoring in the ground. In order to disturb the root growth as little as possible, openings can be provided on the bottom and on the walls of the pot. Plants can grow through them and thereby cause additional fastening and anchoring. In addition, the openings provided at the bottom of the pot reduce the resistance to penetration when the pot is knocked into the upper area of the bottom.

In Fig. 1 erkennt man eine Vorrichtung zum Befestigen von stabförmigen Gegenständen, insbesondere Pfosten, Stangen, Masten, Zaunpfählen und dergleichen, die im Boden oder Erdreich verankert werden sollen. Die Vorrichtung, die nachfolgend als Bodendübel bezeichnet wird, ist in Fig. 1 insgesamt mit dem Bezugszeichen 1 versehen.In Fig. 1 you can see a device for attaching rod-shaped objects, in particular posts, rods, masts, fence posts and the like, which are to be anchored in the ground or soil. The device, which is referred to below as floor dowel, is provided with the reference number 1 overall in FIG. 1.

Der Bodendübel 1 besteht aus einem Rohr mit einer Länge von beispielsweise 60 cm und einem Durchmesser von 40 mm. Der in Fig. 1 nicht dargestellte Gegenstand, beispielsweise ein Zaunpfosten, wird nach dem Einschlagen des Bodendübels 1 in das Rohr 2 eingesteckt.The floor anchor 1 consists of a tube with a length of, for example, 60 cm and a diameter of 40 mm. The object, not shown in FIG. 1, for example a fence post, is inserted into the pipe 2 after the ground plug 1 has been hammered in.

Wie man in Fig. 1 erkennt, ist das Rohr 2 an dem in Fig. 1 nach unten weisenden Ende mit einer Spitze 3 versehen. Die Spitze ist einstückig aus dem vorderen Ende des Rohres hergestellt indem zum vorderen Ende zusammenlaufende Einfaltungen 4 angeformt worden sind. Die Einfaltungen 4 beginnen am Rohrumfang und laufen konisch auf einen Mittelpunkt 5 der Spitze 3 zusammen. Zwischen den einzelnen Einfaltungen 4 befinden sich Rippen 6, die beim Erstellen der Einfaltungen 4 aus dem Rohrmantelmaterial gebildet werden.As can be seen in FIG. 1, the tube 2 is provided with a tip 3 at the end pointing downward in FIG. 1. The tip is made in one piece from the front end of the tube by integrally folding folds 4 have been formed to the front end. The folds 4 begin at the tube circumference and converge conically to a center 5 of the tip 3. Between the individual folds 4 there are ribs 6 which are formed from the tubular casing material when the folds 4 are created.

Während in Fig. 1 die durch vier Einfaltungen 4 hergestellte Spitze 3 in einer Seitenansicht zu erkennen ist, zeigt Fig. 2 die Spitze 3 in einer Ansicht auf die Spitze 3 zu. In Fig. 2 erkennt man dabei die vier Einfaltungen 4 sowie die zwischen den Einfaltungen 4 entstandenen Rippen 6, deren Querschnitt zum vorderen Ende des Rohres hin kontinuierlich abnimmt bis am vorderen Rohrende durch die Rippen 6 eine sternförmige Schneide gebildet ist. Die in dieser Weise aus dem Rohr geformte Spitze 3 ist leicht herstellbar und hat neben dem Vorzug einen geringen Einschlagwiderstand aufzuweisen noch den Vorzug, daß eine Verletzungsgefahr bei der sternförmig zulaufenden Spitze 3 geringer ist als bei einer zu einem Punkt zulaufenden konischen Spitze.While in Fig. 1, the tip 3 made by four folds 4 in a side view 2 shows the tip 3 in a view of the tip 3. 2 shows the four folds 4 and the ribs 6 formed between the folds 4, the cross-section of which decreases continuously towards the front end of the tube until a star-shaped cutting edge is formed by the ribs 6 at the front tube end. The tip 3 formed in this way from the tube is easy to produce and, in addition to the advantage of having a low impact resistance, also has the advantage that the risk of injury with the star-shaped tip 3 is lower than with a conical tip tapering to a point.

Wie man in Fig. 1 weiterhin erkennt, ist am hinteren Ende des Rohres 2 ein Topf 7 ausgebildet, der mit seiner Öffnung 8 in Richtung auf die Spitze 3 weist. Der Topf 7 verfügt über eine Wand 9, die das hintere Ende des Rohres 2 in einem Abstand umgibt, der ein Vielfaches des Durchmessers des Rohres 2 beträgt. Wie man in Fig. 1 erkennt, sind in der Wand 9 eine Reihe von Öffnungen 10 vorgesehen, durch die nach dem Einschlagen des Bodendübels 1 Pflanzenwurzeln hindurchgehen können und so ein Verwachsen des Bodendübels 1 mit dem Boden ermöglichen.As can also be seen in FIG. 1, a pot 7 is formed at the rear end of the tube 2, which has an opening 8 in the direction of the tip 3. The pot 7 has a wall 9 which surrounds the rear end of the tube 2 at a distance which is a multiple of the diameter of the tube 2. As can be seen in FIG. 1, a series of openings 10 are provided in the wall 9, through which plant roots can pass through after the ground dowel 1 has been driven in and thus allow the ground dowel 1 to grow together with the ground.

Auch der Boden 11 des Topfes 7 ist mit Öffnungen 12 versehen, die ein leichteres Eindringen ins Erdreich sowie ein Verwachsen mit dem Pflanzenbewuchs gestatten. Die Öffnungen 10, 12 können eine beliebige Gestalt haben. Vorzugsweise sind sie groß, wobei jedoch die Stabilität des Topfes 7 zum Auffangen eines Biegemomentes noch ausreichend sein muß. Das Biegemoment des eingesetzten Bodendübels 1 ist im Bereich des Topfes 7 als Einspannstelle am größten. Gegenüber einem normalen Rohr ergibt sich durch den Einsatz des Topfes 7 am hinteren Ende des Rohres 2 ein Erdwiderstand, der ein Vielfaches gegenüber einem normalen Rohr beträgt. Selbstverständlich weist der Boden 11 eine zentrale, mit dem Innendurchmesser des Rohres 2 fluchtende Öffnung auf, die in den Figuren 1 und 2 nicht zu erkennen ist.The bottom 11 of the pot 7 is also provided with openings 12, which allow easier penetration into the soil and an overgrowth with the vegetation. The openings 10, 12 can have any shape. They are preferably large, but the stability of the pot 7 must still be sufficient to absorb a bending moment. The bending moment of the floor anchor 1 used is greatest in the area of the pot 7 as a clamping point. Compared to a normal pipe, the use of the pot 7 at the rear end of the pipe 2 results in an earth resistance which is a multiple of that of a normal pipe. Of course, the bottom 11 has a central opening which is flush with the inside diameter of the tube 2 and which cannot be seen in FIGS. 1 and 2.

In Fig. 3 erkennt man einen am Boden 11 ausgebildeten in das Innere des Topfes 7 hineinragenden Rohrstutzen 13 zur Befestigung des Topfes 7 mit dem hinteren Ende des Rohres 2. Der Rohrstutzen 13 greift in das Innere des Rohres 2 ein, das an seinem hinteren Ende über einen erweiterten Bereich 14 verfügt, so daß der Innendurchmesser des Rohres 2 am erweiterten Bereich 14 mit dem Außendurchmesser des Rohrstutzens 13 übereinstimmt und der Innendurchmesser des Rohrstutzens 13 mit dem Innendurchmesser des Rohres 2 möglichst weitgehend identisch ist.In Fig. 3 you can see a formed on the bottom 11 in the interior of the pot 7 protruding pipe socket 13 for fastening the pot 7 with the rear end of the tube 2. The pipe socket 13 engages in the interior of the tube 2, which at its rear end has an enlarged area 14, so that the inside diameter of the tube 2 at the enlarged area 14 matches the outside diameter of the pipe socket 13 and the inside diameter of the pipe socket 13 is as largely as possible identical to the inside diameter of the pipe 2.

Fig. 4 zeigt die am vorderen Ende des Rohres 2 ausgebildete Spitze 3 in einer gegenüber Fig. 1 vergrößerten Darstellung. Man erkennt in Fig. 4 deutlich, wie die Rippen 6 infolge der zusammenlaufenden Einfaltungen 4 in Richtung auf das vordere Ende des Rohres bezüglich ihrer Breite sich konisch verjüngen und bezüglich ihrer Höhe gegenüber den Einfaltungen 4 vergrößern.FIG. 4 shows the tip 3 formed at the front end of the tube 2 in an enlarged view compared to FIG. 1. 4 clearly shows how the ribs 6, due to the converging folds 4 towards the front end of the tube, taper conically in terms of their width and increase in height compared to the folds 4.

Die sich durch die Einfaltungen 4 ergebende Form am Rohrende ergibt sich auch aus Fig. 5, die einen Schnitt durch die mit Hilfe von Einfaltungen 4 aus dem zylindrischen Rohrmantel gebildete Spitze 3 zeigt. Bei dem in den Figuren 1,4 und 5 gezeigten Ausführungsbeispiel sind vier Einfaltugnen 4 vorgesehen, um eine sternförmige Spitze 3 mit vier Zacken oder Armen entstehen zu lassen.The shape resulting from the folds 4 at the tube end also results from FIG. 5, which shows a section through the tip 3 formed with the aid of folds 4 from the cylindrical tube jacket. In the exemplary embodiment shown in FIGS. 1, 4 and 5, four folding troughs 4 are provided in order to create a star-shaped tip 3 with four teeth or arms.

Die Darstellungen der Figuren 6 bis 9 entsprechen im wesentlichen den Darstellungen der Figuren 4 und 5, wobei jedoch die Figuren 6 und 7 eine Spitze 3 mit einem sechsarmigen Sternquerschnitt und die Figuren 8 und 9 eine Spitze mit einem dreiarmigen Sternquerschnitf zeigen. Für gleichartige Teile wurden dabei in den Figuren 6 bis 9 dieselben Bezugszeichen verwendet.The representations of FIGS. 6 to 9 essentially correspond to the representations of FIGS. 4 and 5, but FIGS. 6 and 7 show a tip 3 with a six-armed star cross section and FIGS. 8 and 9 show a tip with a three-armed star cross section. The same reference numerals have been used in FIGS. 6 to 9 for similar parts.

Der Bodendübel 1 wird zum Befestigen eines stabförmigen Gegenstandes im Erdreich an der vorgesehenen Stelle mit seiner Spitze 3 zunächst etwas in den Boden eingedrückt. Anschließend wird der Bodendübel 1 mit Hilfe eines Vorschlaghammers in den Boden eingetrieben, wobei es zweckmäßig ist, auf den nach oben weisenden Boden 11 des Topfes 7 einen in seinen Abmessungen abgestimmten Holzklotz aufzulegen. Während des Eintreibens des Bodendübels 1 ist ein Ausrichten, insbesondere zur Einhaltung eines Lotes, so lange ohne besonderen Kraftaufwand möglich, bis der Topf 7 beginnt, in das Erdreich einzudringen und dieses zu verdichten. Es ist zweckmäßig, den Bodendübel 1 so weit in das Erdreich einzuschlagen, bis der Boden 11 einige Zentimeter, beispielsweise 5 cm, unter der Erdoberfläche oder der Grasnarbe zu liegen kommt. Infolge der Öffnungen 10 in der Wand 9 des Topfes 7 und der Öffnungen 12 im Boden 11 des Topfes 7 können Pflanzen durch den Topf 7 hindurchwachsen, wodurch ein Verwachsen des Bodendübels 1 mit dem Erdreich erfolgt. Nach dem Einschlagen des Bodendübels 1 kann der zu befestigende Gegenstand von oben durch den Rohrstutzen 13 in das Rohr 2 eingetrieben werden, um auf diese Weise eine schnelle und sichere Befestigung des Gegenstandes im Erdreich zu erzielen.The floor plug 1 is first pressed somewhat into the ground with its tip 3 in order to fasten a rod-shaped object in the ground at the intended location. Subsequently, the floor plug 1 is driven into the ground with the help of a sledgehammer, it being expedient to place a block of wood that is matched in its dimensions on the upwardly pointing floor 11 of the pot 7. While driving in the ground plug 1, alignment, in particular to maintain a solder, is possible without any special effort until the pot 7 begins to penetrate the soil and compact it. It is expedient to drive the ground plug 1 into the ground until the ground 11 comes to lie a few centimeters, for example 5 cm, below the surface of the earth or the turf. As a result of the openings 10 in the wall 9 of the pot 7 and the openings 12 in the base 11 of the pot 7, plants can grow through the pot 7, as a result of which the base plug 1 grows together with the ground. After the ground anchor 1 has been driven in, the object to be fastened can be driven from above through the pipe socket 13 into the pipe 2, in order in this way to achieve a fast and secure fastening of the object in the ground.

Bei dem in Fig. 10 dargestellten Ausführungsbeispiel verfügt die Vorrichtung zum Befestigen von stabförmigen Gegenständen, insbesondere Pfosten, im Erdreich über einen Topf 27, dessen Gestalt von einer bei Töpfen üblichen zylinderförmigen Gestalt abweicht. Wie man in Fig. 10 erkennt, sind Einbuchtungen 41 und Ausbuchtungen 42 vorgesehen, so daß die Wand 29 einen schlangenförmigen oder welligen Verlauf hat. Durch einen solchen von der Kreisform nach innen und nach außen abweichenden Verlauf der Wand 29 wird erreicht, daß ein Verdrehen des Topfes 27 um die Längsachse des Rohres 2 oder um das in Fig. 11 mit seinem Ende dargestellte Rohr 22 ein größeres Drehmoment erfordert. Das in Fig. 10 dargestellte Ausführungsbeispiel zeichnet sich somit dadurch aus, daß die Vorrichtung höhere Torsionskräfte aufnehmen kann als eine Vorrichtung mit einem zylinderförmigen Topf 7.In the exemplary embodiment shown in FIG. 10, the device for fastening rod-shaped objects, in particular posts, has a pot 27 in the ground, the shape of which deviates from a cylindrical shape which is customary in pots. As can be seen in Fig. 10, indentations 41 and bulges 42 are provided so that the wall 29 has a serpentine or wavy course. Such a course of the wall 29 which deviates from the circular shape inwards and outwards means that a rotation of the pot 27 about the longitudinal axis of the tube 2 or about the tube 22 shown in FIG. 11 with its end requires a greater torque. The exemplary embodiment shown in FIG. 10 is thus characterized in that the device can absorb higher torsional forces than a device with a cylindrical pot 7.

Wie man in Fig. 10 erkennt, sind im Boden 31 des Topfes 27 mehrere Öffnungen 32 vorgesehen, die auf einem Kreis um eine zentrale Öffnung 20 angeordnet sind.As can be seen in FIG. 10, a plurality of openings 32 are provided in the bottom 31 of the pot 27, which are arranged in a circle around a central opening 20.

In Fig. 11 ist eine Seitenansicht auf einen entlang der Linie XI-XI geschnittenen Topf 27 dargestellt. Der Topf 27 verfügt, wie man in Fig. 11 erkennt, zusätzlich zu den Öffnungen 32 über Öffnungen 30 in seiner wellenförmig oder schlangenförmig verlaufenden Wand 29.11 shows a side view of a pot 27 cut along the line XI-XI. 11, in addition to the openings 32, the pot 27 has openings 30 in its wavy or serpentine wall 29.

Man erkennt in Fig. 11, daß entsprechend der in Fig. 3 dargestellten Ausführungsform am Boden 31 ein in das Innere des Topfes 27 hineinragender Rohrstutzen 33 zur Befestigung des Topfes 27 mit dem hinteren Ende des Rohres 22 vorgesehen ist. Der Rohrstutzen 33 greift in das Innere des Rohres 22 ein, das an seinem hinteren Ende über einen erweiterten Bereich 34 verfügt.It can be seen in FIG. 11 that, according to the embodiment shown in FIG. 3, a pipe socket 33 protruding into the interior of the pot 27 is provided on the bottom 31 for fastening the pot 27 to the rear end of the pipe 22. The pipe socket 33 engages in the interior of the pipe 22, which has an enlarged area 34 at its rear end.

Wie man in Fig. 11 weiter erkennt, verläuft der untere Rand der Wand 29 nicht in einer sich horizontal erstreckenden Ebene, sondern sägezahnförmig. Am unteren Rand sind in der Wand 29 entlang dem Umfang des Topfes 27 mehrere sägezahnförmige Ausnehmungen 40 vorgesehen. Diese Ausnehmungen 40 führen dazu, daß der untere Rand der Wand 29 bei Einwirken von Torsionskräften auf die Vorrichtung einen größeren Drehwiderstand erzeugt. Durch die Kombination des schlangenförmigen Verlaufs der Wand 29 und der sägezahnförmigen Ausnehmungen 40 wird eine besonders große Torsionsfestigkeit erreicht. Gegebenenfalls durch die Öffnungen 30 und 32 eindringendes Wurzelwerk erhöht das von der Vorrichtung aufnehmbare Drehmoment.As can also be seen in FIG. 11, the lower edge of the wall 29 does not run in a horizontally extending plane, but in a sawtooth shape. At the lower edge, a plurality of sawtooth-shaped recesses 40 are provided in the wall 29 along the circumference of the pot 27. These recesses 40 lead to the fact that the lower edge of the wall 29 generates a greater rotational resistance when torsional forces act on the device. The combination of the serpentine course of the wall 29 and the sawtooth-shaped recesses 40 results in a particularly high torsional strength. If necessary, roots penetrating through the openings 30 and 32 increase the torque that can be absorbed by the device.
