Description

Vorrichtung zum Befestigen von stabförmigen Device for fastening rod-shaped
Gegenständen, insbesondere Pfosten, im ErdreichObjects, especially posts, in the ground
Die Erfindung betrifft eine Vorrichtung zum Befestigen von stabförmigen Gegenständen, insbesondere Pfosten, im Erdreich, mit einem einen Kanal für den stabförmigen Gegenstand aufweisenden Rohr.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.
Derartige Vorrichtungen in Gestalt eines einfachen Rohres zum Einsetzen von Pfosten oder dergleichen sind bereits bekannt. Meistens werden jedoch Pfosten und andere stabförmige Gegenstände einfach in den Erdboden eingeschlagen oder im Erdboden betoniert. Beim Einbe- tonieren wird jedoch die Flora und Fauna im Boden be¬ sonders stark geschädigt.Such devices in the form of a simple tube for inserting posts or the like are already known. Most of the time, however, posts and other rod-shaped objects are simply hammered into the ground or concreted in the ground. When concreting in, however, the flora and fauna in the soil are particularly severely damaged.
Ausgehend von diesem Stand der Technik liegt der Erfin¬ dung die Aufgabe zugrunde, eine Vorrichtung der ein- gangs genannten Art zu schaffen, die schnell und ein¬ fach zu setzen ist und die natürlichen Bedingungen im Boden so wenig wie möglich stört.On the basis of this prior art, the object of the invention is to create a device of the type mentioned at the outset which can be set quickly and easily and disturbs the natural conditions in the soil as little as possible.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Rohr an seinem in Einschlagrichtung weisenden vor¬ deren Ende mit einer Spitze versehen ist und im Bereich des hinteren Endes des Rohres konzentrisch ein Ring mit einem größeren Durchmesser als dem Rohrdurchmesser befestigt ist.This object is achieved according to the invention in that the tube is provided with a tip at its front end pointing in the direction of impact and in the region of the rear end of the tube a ring with a larger diameter than the tube diameter is concentrically attached.
Die am vorderen Ende vorgesehene Spitze gestattet das leichte Eintreiben in den Boden und verhindert außer¬ dem, daß sich das Rohr mit Erdreich füllt. Der am hinteren Ende konzentrisch befestigte Ring gestattet eine Arretierung und Stabilisierung des hinteren Endes an der Stelle im Boden, wo das Biegemoment am größten ist. Bei einem zweckmäßigen Ausführungsbeispiel hat der Ring die Gestalt eines umlaufenden Flacheisens, das bei¬ spielsweise mit Speichen oder mit einer Scheibe am Rohrende befestigt ist. Besonders einfache konstruktive Verhältnisse ergeben sich, wenn als Stabilisierungsring ein in Richtung auf die Spitze des Rohres geöffneter Topf vorgesehen ist, dessen umlaufende Wand den Ring darstellt, der mit dem eine konzentrische, mit dem Innendurchmesser des Rohres fluchtende Öffnung auf- weisenden Boden am Rohr befestigt ist. Um den Wurzel¬ wuchs so wenig wie möglich zu stören, sind am Boden und an den Wänden des Topfes Durchbrüche vorgesehen. Durch diese können Pflanzen hindurchwachsen und dabei eine zusätzliche Befestigung und Verankerung bewirken. Außerdem verringern die am Boden des Topfes vorgesehe¬ nen Durchbrüche den Eindringwiderstand beim Einschlagen des Topfes in den oberen Bodenbereich.The tip provided at the front end permits easy driving into the ground and also prevents the pipe from filling with soil. The ring, which is concentrically attached at the rear end, allows the rear end to be locked and stabilized at the point in the floor where the bending moment is greatest. In an expedient embodiment, the ring has the shape of a circumferential flat iron, which is fastened, for example, with spokes or with a washer to the end of the tube. Particularly simple structural conditions result if a pot is provided as the stabilization ring which is open in the direction of the tip of the tube, the circumferential wall of which represents the ring which is fastened to the tube by means of the bottom having a concentric opening which is flush with the inside diameter of the tube is. In order to disturb the root growth as little as possible, openings are 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 Vor¬ richtung, 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 fastening 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 the floor dowel, is provided overall with the reference symbol 1 in FIG. 1.
Der Bodendübel 1 besteht aus einem Rohr 2 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 Einschla¬ gen des Bodendübels 1 in das Rohr 2 eingesteckt. 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.The floor plug 1 consists of a tube 2 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 floor anchor 1 has been hammered in. 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 herge¬ stellte 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 Ein¬ faltungen 4 sowie die zwischen den Einfaltungen 4 ent¬ standenen 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 the tip 3 produced by four folds 4 can be seen in a side view in FIG. 1, FIG. 2 shows the tip 3 in a view towards 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 on the front tube end. The tip 3 formed in this way from the tube is easy to manufacture 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 Ein¬ schlagen des Bodendübels 1 Pflanzenwurzeln hindurchge¬ hen 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, there are a number in the wall 9 of openings 10 are provided, through which plant roots can pass after the ground dowel 1 has been knocked in, thus allowing 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 Biegemomen¬ tes noch ausreichend sein muß. Das Biegemoment des ein¬ gesetzten 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 öff- nung 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 catch a bending moment. The bending moment of the inserted floor anchor 1 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 base 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 Innen¬ durchmesser 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. Fig. 4 zeigt die am vorderen Ende des Rohres 2 ausge¬ bildete 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.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 pipe 2 at the enlarged area 14 corresponds to 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 shows the tip 3 formed at the front end of the tube 2 in an enlarged view compared to FIG. 1. It can be clearly seen in FIG. 4 how the ribs 6, due to the converging folds 4 in the direction of 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 zylin¬ drischen Rohrmantel gebildete Spitze 3 zeigt. Bei dem in den Figuren 1 , 4 und 5 gezeigten Ausführungsbeispiel sind vier Einfaltugnen 4 vorgesehen, um eine sternför- mige 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 Sternquer¬ schnitt 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 einge¬ drückt. 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 Kraft¬ aufwand möglich, bis der Topf 7 beginnt, in das Erd¬ reich 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 hin- durchwachsen, 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 eingetrie¬ ben werden, um auf diese Weise eine schnelle und siche- re Befestigung des Gegenstandes im Erdreich , zu er¬ zielen.The floor plug 1 is first pressed somewhat into the ground with its tip 3 in order to secure a rod-shaped object in the ground at the intended location. Subsequently, the floor plug 1 is driven into the floor with the help of a sledgehammer. During the driving in of the floor anchor 1 is an alignment, in particular for Adherence to a solder, as long as possible without any special effort, until the pot 7 begins to penetrate the soil and compact it. It is expedient to hammer 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 dowel 1 has been driven in, the object to be fastened can be driven into the pipe 2 from above through the pipe socket 13, 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 Ausbuch¬ tungen 42 vorgesehen, so daß die Wand 29 einen schlan- genförmigen 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 zylinder¬ förmigen Topf 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.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 differs 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 corrugated 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. 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 wellen¬ förmig oder schlangenförmig verlaufenden Wand 29.11 shows a side view of a pot 27 cut along the line XI-XI. As can be seen in FIG. 11, the pot 27 has, in addition to the openings 32, 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, in accordance with 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 er¬ streckenden 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 sägezahnför igen Ausnehmungen 40 wird eine besonders große Torsionsfestigkeit erreicht. Gegebenenfalls durch die Öffnungen 30 und 32 eindrin¬ gendes Wurzelwerk erhöht das von der Vorrichtung auf¬ nehmbare 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 rather has 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, root penetration through openings 30 and 32 increases the torque that can be absorbed by the device.
