Reinforcing pins (10) which pass through the head (3) and the anchor pile (2) project upwards from the head and are provided there with lateral anchors. The device is suitable for anchoring construction parts, such as high-tension-line towers, building foundations, etc., in the foundation soil.

Description

Die Erfindung betrifft eine Vorrichtung, die es gestattet, Bauteile wie Hochspannungsmasten, Gebäudefundamente etc. im Erdbereich zu verankern.The invention relates to a device that allows components such as high-voltage pylons, building foundations, etc. to be anchored in the earth.

Der zur Erstellung von Fundamenten im Bausektor und verwandten Gebieten erforderliche Aufwand ist im Vergleich zu den Gesamt-Erstellungskosten erheblich. Zur sicheren Verankerung von Bauteilen, wie Hochspannungsmasten, Gebäudefundamenten etc. sind tiefe Ausgrabungen erforderlich, die mit Beton und verstärkenden Stahleinlagen ausgefüllt werden. Besonders hoch ist der Aufwand naturgemäss in lockerem Boden, speziell in sandigem Terrain, doch bestand bisher das Vorurteil, dass stabile Fundamente nur durch den kombinierten Einsatz von Beton und Stahl erstellt werden können; so zielen die bisher bekannten Verankerungsvorschläge durchwegs darauf ab, im Untergrund des zu verankernden Bauteils einen schweren Unterbau zu schaffen, der schon durch sein Eigengewicht eine gewisse Sicherheit bieten soll.The effort required to create foundations in the construction sector and related areas is considerable compared to the total construction costs. To securely anchor components such as high-voltage pylons, building foundations, etc., deep excavations are required, which are filled with concrete and reinforcing steel inlays. The effort is naturally particularly high in loose soil, especially in sandy terrain, but previously there was a prejudice that stable foundations can only be created by the combined use of concrete and steel; Thus, the previously known anchoring proposals consistently aim to create a heavy substructure in the subsurface of the component to be anchored, which should already offer a certain amount of security due to its own weight.

Diese schweren Stahl-Beton-Konstruktionen durch eine wesentlich leichtere, dennoch aber sehr stabile und praktisch unausreissbar gesicherte Verankerung zu ersetzen, musste daher bisher als unmöglich erscheinen. Und doch ist es die der vorliegenden Erfindung zugrundeliegende Aufgabe, eine Einrichtung zur sicheren Verankerung bzw. Fundamentierung von Bauteilen vorzuschlagen, die sich nicht nur durch ihre unkomplizierte Montage, sondern auch durch ihr extrem geringes Gewicht und ihren geradezu verblüffend hohen Widerstand gegen deren Ausreissen und Einsinken auszeichnet.To replace these heavy steel-concrete constructions with a much lighter, but still very stable and practically unbreakable anchoring, had previously seemed impossible. And yet it is the object on which the present invention is based to propose a device for securely anchoring or foundation of components, which not only stands out due to its uncomplicated assembly, but also due to its extremely low weight and its amazingly high resistance to tearing and sinking distinguished.

Die in Fig. 1 gezeigte Vorrichtung, welche in ihrer Gesamtheit mit 1 bezeichnet ist, weist einen schraubenförmigen Ankerpfahl 2 auf, dessen aus einem Kunststoff hoher Festigkeit, z.B. glasfaserverstärktem Teflon, erstellter Grundkörper mit einem Kopf 3 einteilig, beispielsweise aus einem zähen Kunststoff, hergestellt ist. Der Ankerpfahl 2 weist an seiner Umfangsfläche ein Gewinde 4 auf, an das sich im unteren Teil eine Spitze 5 anschliesst. Letztere besteht vorzugsweise aus einem harten Werkstoff, z.B. Stahl oder Hartmetall, und ist mit dem restlichen Pfahlteil fest verbunden. Je nach Bedarfsfall lässt sich hier auch eine Bohrerspitze anbringen, wie sie beispielsweise für Gesteinsbohrungen verwendet wird.The device shown in Fig. 1, which is designated in its entirety by 1, has a helical anchor post 2, the post of which is made of a plastic of high strength, e.g. glass fiber reinforced Teflon, created body with a head 3 in one piece, for example made of a tough plastic. The anchor post 2 has a thread 4 on its peripheral surface, to which a tip 5 is connected in the lower part. The latter is preferably made of a hard material, e.g. Steel or hard metal, and is firmly connected to the rest of the pile part. Depending on the need, a drill tip can also be attached here, such as that used for rock drilling.

Der Kopf 3 besitzt in seinem Mittelteil eine Ausnehmung 5 in Form eines Sechskantloches und ist an seinem Oberteil durch eine Deckscheibe 6, an seiner nach unten weisenden Ringfläche durch zwei Halbringe 7 abgedeckt. Deckscheibe 6 und Halbringe 7 bestehen vorzugsweise aus Stahl und sind im Werkstoff des Kopfes 3 mittels Schrauben 8 bzw. 9 befestigt. Die Deckscheibe 6 weist im Bereich des Sechskantloches 5 eine ebenfalls sechskantförmige Ausnehmung auf, so dass hier der Sechskant einer Drehvorrichtung angesetzt werden kann.The head 3 has in its central part a recess 5 in the form of a hexagon hole and is on his Upper part covered by a cover plate 6, on its downward facing ring surface by two half rings 7. Cover plate 6 and half rings 7 are preferably made of steel and are fastened in the material of the head 3 by means of screws 8 and 9, respectively. The cover plate 6 has a hexagonal recess in the area of the hexagon hole 5, so that the hexagon of a turning device can be attached here.

Anstelle der im Ausführungsbeispiel dargestellten sechskantförmigen Vertiefung liessen sich selbstverständlich vom Fachmann eine Reihe anderer Organe anbringen, die das Ansetzen einer Drehvorrichtung gestatten.Instead of the hexagonal depression shown in the exemplary embodiment, a number of other organs could of course be made by a person skilled in the art which permit the attachment of a rotating device.

Durch den Kopf 3, einschliesslich der Deckscheibe 6 und der Halbringe 7, sind mehrere Ankerbolzen 10 ins Innere des Ankerpfahles 2 geführt, die an ihren nach oben aus dem Kopf 3 herausragenden Enden mit seitlichen Ankern 11 versehen sind. Je nach Art des vorgesehenen Anschlusses können die herausragenden Enden der Ankerbolzen 10 auch mit anderen Kupplungsteilen ausgebildet sein, die beispielsweise ein Anschrauben der zu verankernden Bauteile gestatten.Through the head 3, including the cover plate 6 and the half rings 7, a plurality of anchor bolts 10 are guided into the interior of the anchor post 2, which are provided with lateral anchors 11 at their ends projecting upward from the head 3. Depending on the type of connection provided, the projecting ends of the anchor bolts 10 can also be formed with other coupling parts which, for example, allow the components to be anchored to be screwed on.

Gemäss Fig. 2 kann der Ankerpfahl aus drei Abschnitten 12, 13, 14 bestehen, die beispielsweise durch Gewindezapfen 15 lösbar miteinander verbunden sind. Während die beiden aussenliegenden Abschnitte 12 und 14 konisch verjüngt sind, ist der Mittelabschnitt 13 in Form einer Zylinderschraube ausgebildet, so dass der beim Eindrehen des Ankerpfahles ins Erdreich zu überwindende Widerstand gegenüber einem über seine Gesamtlänge konischen Ankerpfahl erheblich reduziert ist. Sobald nämlich der Abschnitt 14 voll ins Erdreich eingedrungen ist, ist das für den zylindrischen Abschnitt 13 erforderliche Loch vorgebohrt, sodass erst beim Eindringen des Abschnitts 12 ein weiterer nennenswerter Widerstand auftritt. Dank dieser dreiteiligen Form lässt sich der mittlere, zylindrische Abschnitt 13 in unterschiedlichen Längen auf Lager halten und je nach Bedarfsfall auswechseln. Der Abschnitt 14 kann entweder insgesamt oder nur in seinem unteren, zur Spitze geformten Teil 5 aus einem im Vergleich zum Grundkörper härteren Werkstoff, z.B. Stahl, bestehen.2, the anchor pile can consist of three sections 12, 13, 14, which are detachably connected to one another, for example, by threaded pins 15. While the two outer sections 12 and 14 are tapered, the central section 13 is designed in the form of a cylinder screw, so that the resistance to be overcome when the anchor pile is screwed into the ground is considerably reduced compared to a conical anchor pile over its entire length. As soon as section 14 has penetrated fully into the ground, the hole required for cylindrical section 13 is pre-drilled, so that no further significant resistance occurs until section 12 penetrates. Thanks to this three-part shape, the central, cylindrical section 13 can be different Keep lengths in stock and replace if necessary. The section 14 can either consist entirely or only in its lower, tip-shaped part 5 made of a material that is harder than the base body, for example steel.

Eine Variante, die sich insbesondere zur Verankerung schwerer Bauteile in lockerem Baugrund, beispielsweise Sand, eignet, zeigt Fig. 3. Hier ist in den Ankerpfahl 2, der im übrigen mit der Ausführungsform nach Fig. 1 übereinstimmt, ein zentrales Sackloch 16 gebohrt, an das sich seitlich Austrittskanäle 17 anschliessen. Diese Ausbildung gestattet es, nach dem Eindrehen des Ankerpfahles 2 ins Erdreich von oben in Pfeilrichtung ein Erdreich-verfestigendes Mittel, z.B. ein Kunstharz oder ein Gemisch von Zement und Wasser (Zementmilch) einzugiessen, das das den Ankerpfahl umgebende Erdreich durchdringt und nach dem Aushärten eine verfestigte Zone Z bildet, die dem Ankerpfahl zusätzlichen Widerstand gegen das Ausreissen und Einsinken bzw. Kippen verleiht.FIG. 3 shows a variant which is particularly suitable for anchoring heavy components in loose subsoil, for example sand. Here, a central blind hole 16 is drilled in the anchor post 2, which otherwise corresponds to the embodiment according to FIG the outlet channels 17 connect laterally. This design allows, after screwing the anchor pile 2 into the ground from above in the direction of the arrow, a ground-strengthening agent, e.g. Pour in a synthetic resin or a mixture of cement and water (cement milk) that penetrates the soil surrounding the anchor post and, after hardening, forms a solidified zone Z, which gives the anchor post additional resistance to pulling out and sinking in or tipping over.

Die Wahl des Gewindes 4, das in jedem Falle als scharfgängiges Gewinde mit spitzen Flanken ausgebildet ist, kann den vorherrschenden Bodenbedingungen angepasst werden. So wird man, wie in Fig. 4 veranschaulicht, die Variante a mit grossem Flankenwinkel α von 25 bis 60° für harte Böden, die Variante b mit kleinem Flankenwinkel β zwischen 0 und 25° für leichte, sandige Böden wählen. Um ein unbeabsichtigtes Rückdrehen des einmal ins Erdreich eingedrehten Ankerpfahles zu verhindern, können die Gewindeflanken mit Widerhaken 18 versehen sein, wie dies die Variante c in Fig. 4 darstellt.The choice of thread 4, which is in any case designed as a sharp thread with pointed flanks, can be adapted to the prevailing soil conditions. Thus, as illustrated in FIG. 4, variant a with a large flank angle α of 25 to 60 ° for hard soils, variant b with a small flank angle β between 0 and 25 ° for light, sandy soils will be selected. In order to prevent an unintentional turning back of the anchor pile once screwed into the ground, the thread flanks can be provided with barbs 18, as shown by variant c in FIG. 4.

Auch wäre es möglich, den Ankerpfahl, wie Fig. 5 zeigt, in Form einer konisch zulaufenden archimedischen Schraube S auszubilden, die sich in leichte, sandige Böden eindrehen lässt. Die Schraube könnte aus einem Stahlblech geeigneten Zuschnitts mit scharfen Seitenkanten gedreht werden.It would also be possible to form the anchor pole, as shown in FIG. 5, in the form of a conically tapering Archimedean screw S which can be screwed into light, sandy soils. The screw could be turned from a sheet of steel with a suitable cut and sharp side edges.

Eine Anwendung der Vorrichtung, wie sie insbesondere in Fig. 1 dargestellt ist, zeigt Fig. 6. Ein auf vier Pfeilern 19 ruhender Hochspannungsmast stützt sich auf Betonelemente 20 ab, die ihrerseits mittels erfindungsgemässen Ankerpfählen 21 im Boden verankert sind. Die Verbindung der Ankerpfähle 21 mit den Betonelementen 20 erfolgt vorzugsweise dadurch, dass die Ankerpfähle 21 mit verzweigungsförmigen Ankern versehen sind, wie sie in Fig. 1 mit 11 bezeichnet wurden, über die dann ein Betonblock 20 gegossen wird. An den herausragenden Köpfen der Anker lassen sich dann die Pfeiler 19 in bekannter Weise verschrauben oder anschweissen.An application of the device, as shown in particular in FIG. 1, is shown in FIG. 6. A high-voltage pylon resting on four pillars 19 is supported on concrete elements 20, which in turn are anchored in the ground by means of anchor piles 21 according to the invention. The connection of the anchor piles 21 to the concrete elements 20 is preferably carried out in that the anchor piles 21 are provided with branched anchors, as they were designated in FIG. 1 by 11, over which a concrete block 20 is then poured. The pillars 19 can then be screwed or welded to the protruding heads of the anchors in a known manner.

Das Eindrehen kleiner Verankerungsvorrichtungen kann in lockerem Boden von Hand, gegebenenfalls unter Ausnutzung der Hebelwirkung, erfolgen. Bei grösseren Abmessungen der Ankerpfähle und schwereren Böden erfolgt das Eindrehen auf maschinellem Wege. Dafür kann beispielsweise ein Lastwagen oder Traktor 22 eingesetzt werden, an dessen Getriebe über eine Zapfwelle eine Drehvorrichtung 23 angeschlossen ist. Diese greift mit ihrem Sechskant in den Kopf 24 der einzudrehenden Ankervorrichtung 25 (Fig. 7).Small anchoring devices can be screwed in by hand in loose soil, possibly using leverage. With larger dimensions of the anchor piles and heavier floors, they are screwed in mechanically. For example, a truck or tractor 22 can be used for this purpose, to whose transmission a rotary device 23 is connected via a PTO shaft. This engages with its hexagon in the head 24 of the anchor device 25 to be screwed in (FIG. 7).

Die erfindungsgemässe Vorrichtung kann beispielsweise in der in Fig. 3 gezeigten Ausführung für die Verankerung von Gebäudefundamenten Verwendung finden. Die in Fig. 8 mit 26 bezeichneten Vorrichtungen werden zunächst in das Erdreich eingedreht, bis deren Köpfe 27 noch um ein gewisses Mass aus dem Erdreich herausragen, worauf die Anker 28 angebracht werden. Nun wird von oben in die Bohrungen 29 Zementmilch eingegeben, die das umgebende Erdreich durchtränkt und nach dem Aushärten eine Zone Z hoher Festigkeit bildet. Das Betonfundament 30 wird dann über die Ankerköpfe 27 gegossen und durch dieselben fest verankert. Je nach der angestrebten Stabilität der Verankerung lassen sich die Vorrichtungen auch ohne Zugabe von Zementmilch mit ausreichender Sicherheit montieren.The device according to the invention can be used, for example, in the embodiment shown in FIG. 3 for anchoring building foundations. The devices designated 26 in FIG. 8 are first screwed into the ground until their heads 27 still protrude from the ground to a certain extent, whereupon the anchors 28 are attached. Now cement milk is introduced into the holes 29 from above, which soaks the surrounding soil and forms a zone Z of high strength after hardening. The concrete foundation 30 is then poured over the anchor heads 27 and firmly anchored by the same. Depending on the desired stability of the anchoring, the devices can be assembled with sufficient security even without adding cement milk.

Die beschriebene Vorrichtung zeichnet sich, wie sich durch einfache Versuche nachweisen lässt, durch einen ausserordentlich hohen Widerstand gegen das Ausreissen und Einsinken in Richtung der Ankerpfahlachse aus, da die Summe der ins Erdreich eingedrehten Gewindeflanken eine sehr grosse Gesamtfläche bildet, auf der sich der Ankerpfahl einer Verschiebung widersetzt.The device described is characterized, as can be demonstrated by simple tests, by an extraordinarily high resistance to pulling out and sinking in the direction of the anchor pile axis, since the sum of the threaded flanks screwed into the ground forms a very large total area on which the anchor pile forms Resists displacement.

Die beschriebenen Ausführungsformen sind lediglich der Veranschaulichung dienende Beispiele, die vom Fachmann beliebig vermehrt werden können. So lassen sich mit der erfindungsgemässen Vorrichtung zweifellos auch Bojen im Seegrund, Spannseile von Zelten im Wüstensand etc. etc. auf relativ unkomplizierte Weise festmachen.The described embodiments are merely illustrative examples that can be expanded as desired by a person skilled in the art. Thus, with the device according to the invention, it is undoubtedly also possible to attach buoys in the lake bed, tension cables of tents in the desert sand etc. etc. in a relatively uncomplicated manner.

Im praktischen Einsatz hat die Vorrichtung eine Gesamtlänge zwischen beispielsweise 0,5 bis 5 m, doch kann sie in Sonderfällen sogar beträchtlich länger sein. Bei extremen Längen kann es von Vorteil sein, zuerst ein Kernloch vorzubohren und dann die Vorrichtung in das Kernloch, dessen Durchmesser etwa die Hälfte des mittleren Gewindedurchmessers betragen sollte, einzudrehen.In practical use, the device has a total length of between 0.5 to 5 m, for example, but in special cases it can even be considerably longer. In the case of extreme lengths, it may be advantageous to first predrill a core hole and then screw the device into the core hole, the diameter of which should be approximately half the average thread diameter.

Die in Fig. 9, 10 und 11 dargestellte Variante zeigt wiederum einen mit scharfgängigem Gewinde 30 versehenen Ankerpfahl 31 mit einer Kopfplatte 32. Der Grundkörper des Ankerpfahles 31 weist allerdings keine Spitze auf und ist bei dieser Ausführungsform mit einer zentralen Durchgangsbohrung 33 versehen. Ein Sondierstab 34 aus gehärtetem Stahl weist eine Sondierspitze 35, einen stabförmigen Mittelteil 36, einen Mitnehmer 37 und ein Anschlussstück 38 auf. Der Mitnehmer 37 von quadratischem Querschnitt ist in Form und Grösse dem oberen Abschnitt der Durchgangsbohrung 33 angepasst, so dass sich der Sondierstab 34 soweit in die Durchgangsbohrung 33 einschieben lässt, bis dessen Spitze 35 aus der unteren Oeffnung der Durchgangsbohrung 33 herausragt und damit die harte Spitze des Ankerpfahles bildet.The variant shown in FIGS. 9, 10 and 11 in turn shows an anchor post 31 provided with a sharp thread 30 with a head plate 32. However, the base body of the anchor post 31 has no tip and is provided with a central through hole 33 in this embodiment. A probing rod 34 made of hardened steel has a probing tip 35, a rod-shaped central part 36, a driver 37 and a connecting piece 38. The driver 37 of square cross-section is adapted in shape and size to the upper section of the through hole 33, so that the probing rod 34 can be inserted into the through hole 33 until its tip 35 protrudes from the lower opening of the through hole 33 and thus the hard tip of the anchor pile.

Bevor der Ankerpfahl nun in einen zunächst unbekannten Boden eingebracht wird, stösst man zunächst den Sondierstab 34 nach unten ins Erdreich, um festzustellen, ob sich die gewählte Stelle eignet bzw. mit Gestein durchzogen ist. Lässt sich der Sondierstab 34 ohne Schwierigkeiten nach unten stossen, so wird er herausgezogen, in den Ankerpfahl 31 eingeschoben und am Anschlussteil 38 an eine Drehvorrichtung angeschlossen. Nach dem Einbringen des Ankerpfahles kann der Sondierstab entweder herausgenommen werden oder auch im Erdreich verbleiben.Before the anchor post is now placed in an initially unknown soil, the probing rod 34 is first pushed downwards into the ground in order to determine whether the selected location is suitable or has been criss-crossed with rock. If the probing rod 34 can be pushed down without difficulty, it is pulled out, inserted into the anchor post 31 and connected to a rotating device on the connecting part 38. After the anchor post has been inserted, the probing rod can either be removed or can remain in the ground.
