mit einem Schaft, der im Bereich seines oberen Endes einen auf den Boden
aufsetzbaren Auflageteil und eine Handhabungsvorrichtung aufweist,
mit mehreren sich um den Schaft windenden Schraubenwindungsklingen aus
flächigem Material, die längs des Schaftes mit gegenseitigem Abstand versetzt
angeordnet sind und jeweils aus einer Schraubenwindung mit oberen und unteren
Klingenenden bestehen,
wobei die Windungslänge der einzelnen Klingen auf etwas mehr als 360° bemessen
ist, sodass sich die Klingenenden unter Ausbildung eines oben und unten flächig
begrenzten Schneidspaltes in Umfangsrichtung überlappen,
mit einem sich vom Auflageteil zum unteren Schaftende hin von Klinge zu Klinge
verringernden Außendurchmesser der Klingen.The invention relates to an earth anchor for screwing into the ground, with a shaft that has a support part that can be placed on the ground in the region of its upper end and a handling device, with a plurality of helical winding blades made of flat material that wind around the shaft and that run along the shaft are arranged offset from one another and each consist of a screw turn with upper and lower blade ends,
the winding length of the individual blades being dimensioned at a little more than 360 °, so that the blade ends overlap in the circumferential direction to form a cutting gap which is delimited at the top and bottom,
with an outer diameter of the blades that decreases from the support part to the lower shaft end from blade to blade.
Ein derartiger Erdanker ist aus der DE 44 24 339 C2 bekannt. Dieser Erdanker hat sich in der Praxis bewährt. Er hat eine gute Standfestigkeit auch in sandigen Böden.Such an earth anchor is known from DE 44 24 339 C2. This ground anchor has proven itself in practice. It has good stability even in sandy soils.
Es ist Aufgabe der Erfindung, die Standfestigkeit dieses Erdankers weiter zu erhöhen und ihn so zu verändern, dass er sich leichter in den Boden eindrehen lässt.It is an object of the invention to further increase the stability of this ground anchor and to change it so that it is easier to screw it into the ground.
Ausgehend vom Oberbegriff des Anspruchs 1, der sich auf die oben zitierte Fundstelle stützt, ist die gestellte Aufgabe erfindungsgemäß durch die weiteren Merkmale dieses Anspruchs gelöst Art eines Holzschraubenschaftes ausgebildet ist mit einem sich zum freien unteren Schaftende kegelig zuspitzenden Kern und einer sich um den Kern windenden.Starting from the preamble of claim 1, which is based on the above-mentioned reference, the object is achieved according to the invention by the further features of this claim Kind of a wood screw shank is formed with a free lower one Shanking tapered core and one winding around the core.
Ein Erdanker mit dieser Schaftspitze hat nach seinem Eindrehen in den Boden eine erhöhte Standfestigkeit. Von wesentlicher Bedeutung ist aber, dass er sich leichter in den Boden eindrehen lässt. Dies beruht darauf, dass die holzschraubenförmige Schaftspitze den Schaft mit den auf Abstand angeordneten Klingen nach unten zieht und damit die auf Abstand angeordneten Klingen beim Eindrehen oder Einschrauben nach unten auf Zug belastet sind. Sie schneiden sich damit nach unten gezogen in den Boden ein. An earth anchor with this shaft tip has one after screwing it into the ground increased stability. It is essential, however, that he is easier in lets the floor screw in. This is because the wood screw shaped Shaft tip pulls the shaft down with the spaced blades and thus the spaced blades when screwing in or screwing in are loaded down on train. They cut themselves down into the Bottom one.
Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, dass der Steigungswinkel der Schraubengangwindung im Bereich des Kernes der Schaftspitze größer ist als der Steigungswinkel der auf Abstand angeordneten Klingen. Mit diesem erhöhten Steigungswinkel belastet die Schaftspitze den Erdanker beim Einschrauben verstärkt nach unten.According to a further embodiment of the invention it is provided that the Helix turn angle in the area of the core of the shaft tip is greater than the pitch angle of the spaced blades. With this Increased pitch angle loads the shaft tip on the ground anchor when screwing in intensified down.
Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, dass die Schraubengangwindung im Bereich der Schaftspitze ein sich vom Kern nach außen hin keilförmig zuspitzendes Querschnittsprofil aufweist. Dieses sich keilförmig zuspitzende Querschnittsprofil macht die Schaftspitze zu einer Art Bohrer, der sich in den Boden eingräbt.According to a further embodiment of the invention it is provided that the Screw thread turn in the area of the shaft tip extends from the core to the outside has a wedge-shaped tapering cross-sectional profile. This is wedge-shaped tapering cross-sectional profile turns the shaft tip into a kind of drill that fits into digs the ground.
Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, dass die Höhe der Schraubengangwindung, abgesehen von dem Auslaufbereich am freien Ende der Schaftspitze, im wesentlichen gleichbleibend ist.According to a further embodiment of the invention it is provided that the height of the Screw thread turn, apart from the outlet area at the free end of the Shaft tip, is essentially constant.
Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, dass die Schaftspitze am Schaft genau zentriert angeordnet ist. Eine genaue Zentrierung ist wichtig für einen leichten und sauberen Einlauf in den Boden.According to a further embodiment of the invention, it is provided that the shaft tip is precisely centered on the shaft. Precise centering is important for easy and clean entry into the floor.
Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, dass die Kugelschale im Taumelkopf mittels einer Klemmschraube in einer eingestellten Taumelstellung arretierbar ist. Unbedachtes oder unerwünschtes Verstellen der vorgesehenen Stellung des Taumelkopfes lässt sich so vermeiden.According to a further embodiment of the invention it is provided that the Ball cup in the swash head by means of a clamping screw in a set Tumble position can be locked. Careless or unwanted adjustment of the intended position of the swash head can be avoided.
Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, dass die Klemmschraube eine Madenschraube ist.According to a further embodiment of the invention it is provided that the Clamping screw is a grub screw.
Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, dass die unterste der auf Abstand angeordneten Klingen an der unteren Endkante eine gegenüber den übrigen auf Abstand angeordneten Klingen verstärkte Kröpfung aufweist. Diese verstärkte Kröpfung der unteren Endkante fördert das erleichterte Einschrauben.According to a further embodiment of the invention it is provided that the bottom of the spaced blades at the lower end edge one opposite the remaining blades spaced apart has reinforced cranking. This Increased cranking of the lower end edge promotes easier screwing in.
Der Erdanker lockert beim Einschrauben in den Boden diesen auf. Es wurde vermutet, dass der Erdanker deshalb einen weniger festen Sitz hat. Dies ist aber ein Irrtum. The ground anchor loosens when screwing it into the ground. It was suspected that the ground anchor is therefore less secure. But this is a mistake.
Gerade durch das Auflockern werden die Sitzfestigkeiten und damit die Belastbarkeit erhöht.By loosening up the seat strength and thus the resilience elevated.
Der Erdanker wird in seiner Dimensionierung an die jeweiligen Einsatzverhältnisse angepasst. Er eignet sich von der kleinsten Dimension, beispielsweise bei der Zeltverankerung, bis zu großen Dimensionen beim Einsatz zur Fundamentsicherung im Gebäudebau.The dimensioning of the ground anchor depends on the particular application customized. It is suitable for the smallest dimension, for example the Tent anchorage, up to large dimensions when used to secure foundations in building construction.
Die Erfindung wird anhand der Zeichnung näher erläutert.The invention is explained in more detail with reference to the drawing.
Die Zeichnung zeigt einen Erdanker mit einem Schaft, an dessen oberem Ende ein Auflageteil und eine Handhabungsvorrichtung vorgesehen sind. Längs des Schaftes sind auf Abstand einzelne Schraubenwindungsklingen angeordnet. Die in den Boden eindringende, unten befindliche Schaftspitze ist als Holzschraubenschaft ausgebildet. Sie läuft kegelförmig zum freien Ende hin zu und ist an der Außenwand mit einer durchgehend umlaufenden, als Gewinderippe ausgebildeten Schraubenwindung versehen, deren Steigungswinkel größer ist als der der auf Abstand angeordneten einzelnen Schaubenwindungsklingen.The drawing shows an earth anchor with a shaft, at the top of which one Support part and a handling device are provided. Along the shaft individual screw winding blades are arranged at a distance. The one in the ground penetrating shaft tip located below is designed as a wood screw shaft. It runs conically towards the free end and is on the outer wall with one continuous screw thread formed as a thread rib provided, the pitch angle is greater than that of the spaced individual screw turn blades.
Der in der Zeichnung dargestellte Erdanker 1 besteht aus einem Schaft 3, der an
seinem oberen Ende mit einem Auflageteil 8 versehen ist. Das Auflageteil 8 besteht
aus einem Teller 8a und einem Kragen 8b, der sich völlig in sich geschlossen vom
Rand des Tellers 8a nach unten erstreckt. Der Durchmesser des Auflageteiles 8 ist
beispielsweise 4 cm größer als der von Schraubenwindungsklingen 5,6,7, die sich auf
gegenseitigem Abstand längs des Schaftes 3 verteilen und noch näher beschrieben
werden. Die Durchmesserdifferenz kann auch größer als 4 cm sein. An dem Teller 8a
ist eine Befestigungsvorrichtung 9 angebracht, vorzugsweise angeschweißt. Der Schaft
3 greift durch den Teller 8a bis in die Befestigungsvorrichtung 9 hinein.The ground anchor 1 shown in the drawing consists of a
Die Klingen 5.6.7 am Schaft 3 bestehen aus flachem Blechmaterial. Sie winden sich
einzeln um den Schaft 3 und haben eine Windungslänge, die etwas größer ist als die
Länge eines vollen Windungsganges von 360°. Auf diese Weise ergibt sich bei jeder
Klinge 5,6,7 jeweils zwischen dem oberen Klingenende 11 und dem unteren
Klingenende 12 im Überlappungsbereich ein Schneidspalt 11a. Die Überlappung kann
25 bis 55 Winkelgrade betragen. Vorzugsweise werden 35 bis 45 Winkelgrade
eingesetzt. Die Klingen 5,6,7 verlaufen in Ebenen radial zum Schaft 3. Während die
Klingen 5,6,7 an ihren oberen Endkanten 11b vorzugsweise in der Klingenebene 11c
auslaufen, sind die unteren Endkanten 12b nach unten abgekröpft. Die Abkröpfung an
der unteren Endkante 12b der untersten Klinge 7 ist dabei deutlicher ausgeprägt als die
der anderen Klingen 5,6. Die Abkröpfungen der Endkanten 12b haben einen positiven
Einfluss auf die Einschaubwirkung des Erdankers. Die Steigungen der Klingen 5,6,7
sind aneinander angepasst. Der Außendurchmesser der Klingen 5,6,7 verringert sich
vom Auflageteil 8 zur Schaftspitze 10 nach unten gleichmäßig. Die oberste Klinge 5
hat einen Abstand vom Auflageteil 8, der geringer sein kann als der gegenseitige
Abstand der Klingen 5,6,7.The blades 5.6.7 on the
Die Handhabungsvorrichtung 9 weist einen Taumelkopf 13 auf, der beispielsweise
durch Anschweißen an dem Teller 8 festgelegt ist. Dieser Taumelkopf 13 hat außen
eine vier- oder sechskantige Gestaltung zum Ansetzen eines nicht dargestellten
Drehwerkzeuges. Mit Hilfe eines solchen Werkzeuges lässt sich der Erdanker in den
Boden einschrauben. Der Taumelkopf 13 hat eine kugelschalenförmige Mulde 13a. In
diese Mulde 13a ist eine Kugelschale 14a eingelegt, an die beispielsweise ein Rohr 14
angeschweißt sein kann. Die Kugelschale 14a mit dem Rohr 14 lässt sich in Grenzen
in eine gewünschte Schwenklage einstellen. Die Kugelschale 14a ist, um schwenkbar
zu sein, am Boden mit einem Durchbruch 14b versehen. In die Kugelschale 14a wird
eine KLemmschale 15 eingelegt. Mittels einer durch die Klemmschale 15 und die
Kugelschale 14a in eine Gewindebohrung 13b des Taumelkopfes 13 geschraubten
Stellschraube 17 wird die Kugelschale 14a in der erwünschten Lage fest mit der
Klemmschale 15 verbunden. Dafür muss der Durchbruch 14b in der Kugelschale 14a
groß genug sein. An das Rohr 14 kann beispielsweise ein Zaunrohr 18 angesetzt
werden. Befestigungsschrauben 19 können die Rohre 14 und 18 verbinden.
In dem Taumelkopf 13 ist eine Madenschraube 20 vorgesehen, die nach dem
Ausrichten der Kugelschale 14a mit dem Rohr 14 eingedreht wird und dabei gegen die
Kugelschale 14a drückt; sie gräbt sich in diese ein und legt sie damit in der
vorgesehen Schwenklage fest.The
