Definitions

  • the invention relates to a ground anchor anchored in the soil according to the preamble of claim 1 or 2.
  • Ground dowel in particular in the soil einfitbare ground dowel with downwardly conically tapered cross-section and a spiral on its outer surface extending downward, radially projecting ribs, which serve for holding and supporting objects, in particular of pile or tubular objects are known in a variety of embodiments for a relatively long time. So is such a ground dowel example of the DE-OS 3303919 (Disclosure: 09.08.84) previously known, in which a ball joint is provided between the object to be held and the ground anchor anchored in the ground. This ball joint serves for adjusting and in particular vertical alignment of the object relative to the ground dowel longitudinal axis and is locked in the aligned position, for example by an adhesive or mechanical fastening means.
  • the ball or the spherical joint part of this ball joint is firmly connected to the upper end of the ground dowel and protrudes into a bearing cup, which is provided on the underside of a support and receiving part.
  • This support and receiving part is placed on top of the ball and serves to receive the lower end of the objects to be held. Since in this known construction, the ball or the spherical joint part of the ball joint is rigidly connected to the ground dowel, the object to be held, while vertically aligned, but can not be adjusted in height.
  • DE-OS 4002830 (Disclosure: 20.09.90), as there also held by the ground dowel object is rigidly connected to the ground dowel.
  • a support for posts and the like using a ball joint is also the DE-GM-8809142.2 font (notice in the patent: 22.12.88) refer.
  • the housing of the ball joint accommodating the ball or the spherical joint part is firmly anchored directly on the earth surface and has an opening at the top through which a cylindrical pin part formed on the ball or the spherical joint part extends upward.
  • This pin member protrudes into the lower inner end of the tubular article to be held and is firmly bolted to the same.
  • the tubular article itself rests on the upper end of the housing receiving the ball or spherical joint member and can be vertically aligned by twisting the ball or spherical joint member due to the rigid connection between the pin member and its lower end.
  • the housing is in two parts and can be clamped by a screw connection with the ball or the spherical joint part, it is also possible here to set and lock the tubular article in its vertically oriented position.
  • a height adjustment of this object is also not possible in this prior art, since the tubular article must sit on the ball housing and is firmly connected to the pin part of this ball or the spherical joint part.
  • a similar construction as the one according to DE-GM-8809142.2 is from the figure 4 and the associated description text of DE-OS 3912064 (Disclosure: 18.10.90) removed, in which also a firmly anchored to the surface of the earth holding member using a ball joint supports a tubular object.
  • the ball or the spherical joint part consists here of a firmly anchored on the surface of the soil base part as a holding part of one piece and protrudes upward in a bearing cup, in the lower end of the tubular to holding object is formed.
  • the lower end of the article is tightened by screwing firmly with the ball or the spherical joint part here, too. Due to the immovably stuck in the lower end of the tubular article bearing cup height adjustment of the object to be held can not be realized even in this prior art.
  • This rod-shaped extension can be inserted into a tube attached to the upper end of the ground anchor and can be clamped to the pipe by means of a screw in a threaded hole provided in the pipe vertically to the pipe axis.
  • the ball or the spherical joint part which is taken up by this bearing cup, is firmly connected to the lower end of the object to be held, such as a fence post, or consists of one piece with this lower end.
  • the present invention is based on the object to provide a novel ground anchors anchored in the ground, which allows both a height adjustment of the ground dowel to be held object and a setting or vertical orientation of this object relative to the ground dowel axis with a simple structure.
  • Claim 2 is an independent ancillary claim with an identical to claim 1 generic term, the subject of this claim 2 differs from that of claim 1 only in that omitted in the subject of claim 2 in the ball or the spherical joint part of the ball joint used the longitudinal slot is and only the diametrical opening channel is present.
  • the material of the slit-free ball or of the slit-free spherical joint part must be chosen to be so resilient that, despite this lack of longitudinal slot, the object projecting into the opening channel is firmly clamped to the ball joint when a corresponding clamping pressure is exerted.
  • the material of the slot-free ball or the slot-free spherical joint part may be chosen to be more flexible than that of the ball or the spherical joint part with slot.
  • this measure is not an unconditional prerequisite for the feasibility of the two characterized in the claims 1 and 2 objects, since even with the use of the same material with a correspondingly chosen flexibility in both cases, a sufficient clamping force can be developed, but with a slightly different size.
  • the ball joint can then be locked by exerting a corresponding clamping pressure on the ball or the spherical joint part, wherein by reducing the slot width in the ball or the spherical joint part or by the flexibility of the material from which the ball or the spherical joint part is, the cross-section of the opening channel are reduced so that the object to be held firmly with the ground dowel connected is.
  • the diameter of the opening channel is equal to or slightly larger compared to that of the lower end portion of the article chosen, of course in the latter Trap when exercising the clamping pressure still a sufficiently large clamping action must be achieved.
  • the measure according to the current claim 8 ensures that the width of the longitudinal slot in the upper dowel end portion and associated with the bearing cup cross section in the direction transverse to the dowel axis can be reduced by applying a relatively low clamping force to the subject in question within the ball or clamp the opening provided in the spherical joint part.
  • the longitudinal slot with the bracing device is provided on the upper plug end section and thus on the earth's surface, the object inserted into the ground anchor and aligned, such as a fence post, can be used by the operator be held one hand while the operator operates with the other hand, the bracing and thus determines the object in its aligned position and clamps. This ensures a very convenient handling of the anchor construction according to the invention.
  • the measures, as characterized in the claims 11 and 12, describe a convenient and practical manufacturing form of a ground anchor according to the invention, wherein extending to the lower dowel end hollow chamber height adjustment of the object to be held in a relatively large area while secure anchoring this Ensures article within the ground anchor, as the force exerted by the ball or the spherical joint part clamping force is generated on the object at a distance from its lower end face and the hollow chamber inner wall can additionally serve as a stop or abutment surface for the lower end portion of the article.
  • a support member cooperating with the ground dowel will usefully accommodate the lower end of the stem to be retained An article of use as claimed in claim 14.
  • Such support members are in themselves from the above cited above DE-GM-document 29922142 and Figures 3 and 4 of DE-OS 4428028 previously known.
  • the support plate of the support member according to the invention is smaller than the cross section of the supported object, it is ensured that rainwater can not collect on the support plate and damage the object resting on it, but runs down into the soil.

  • the spherical joint part 3a has a slot 3d extending radially outward from the opening channel 3c over its entire axial length as far as the lateral surface of the spherical joint part 3a, whose width can be reduced by exerting a correspondingly large clamping pressure on the spherical joint part 3a in the direction transverse to the plane of the two slot walls 3e and 3f. In this way, the lower end portion 2a of the article 2 can be clamped by reducing the cross section of the opening channel 3c therein.
