Abstract

The invention relates to a stabilizer with an adjusting device for ground anchorages in the form of a ground anchor (1), for example a peg, flagpole, traffic pole, earth screw or Krinner anchor, characterized in that a stabilizer baseplate (10) is attached in an interlocking or frictional manner to the ground anchor (1) and rods (11, 12) which are connected to said stabilizer baseplate protrude through the latter and are anchorable in the ground. The problem is to attach an additional stabilizing device to a ground anchor already fitted in the ground, said stabilizing device being suitable for additionally stabilizing the ground anchor, substantially increasing the pull-out forces and improving the stability against tilting.

Description

Stabilizer with leveling device for ground anchors

The invention relates to a stabilizer with adjusting device for ground anchors according to the preamble of claim 1.

Ground anchors for the purposes of the present invention are all earth-anchored fasteners, as used in particular for traffic masts, flagpoles, carport foundations and the like.

Especially with traffic pylons there is the problem of straightening them up when damage has taken place that is so strong that the mast is no longer securely anchored to the ground. It is then extremely complicated to fix such, partially lifted from the ground or in the ground only loosely anchored ground anchorage again.

As a rule, this is repaired at great expense by excavating the entire ground anchoring, re-compacting the ground and then reinstalling the ground anchoring. Incidentally, all ground anchors engaging vertically in the ground have the disadvantage that they are only slightly loadable against tensile forces, ie. H. the pull-out forces in the vertical direction are relatively low, to solve such a ground anchor again.

Ground anchors of the type mentioned are known for example with the subject of AT 008142 U2.

The ground anchoring referred to there as an alpine anchor consists of a central peg, which is connected to a disc, which has distributed around the circumference arranged recesses are screwed through the transversely driven into the ground or screwed threaded rods.

Such an alpine anchor has proven itself, but is not suitable to be attached to already existing ground anchors. Incidentally, the same also applies to US Pat. No. 6,871,455 B1, which likewise shows a disk, on the underside of which a ground disk, which is screwed into the ground and can be pivoted, is present.

Also this disc is anchored by means of threaded rods in the ground.

Such a holder is also not suitable to form an additional stabilization in an already existing ground anchor.

The invention is therefore based on the object to cultivate an additional stabilizing device on a ground anchor already installed in the ground, which is suitable to stabilize the ground anchor in addition, to significantly increase the pull-out and to improve the tipping stability.

The object is achieved by the technical teaching according to the invention according to claim 1.

An essential feature of the invention is that on an existing ground anchor, the z. B. as peg, flagpole, traffic mast, earth screw or Krinneranker an additional stabilizer base plate is attached, which is positively and non-positively connected to the existing ground anchor and that project through the stabilizer base plate transversely extending and obliquely projecting into the soil rods and connected to the stabilizer base plate.

With the given technical teaching, there is the significant advantage that the invention provides that the conventional ground anchor (peg, flagpole, traffic mast, earth screw or Krinneranker) is now subsequently connected to an adapter system, which preferably in a first embodiment of a stabilizer base plate exists, which is positively and non-positively connected to the ground anchor. It is important that this stabilizer base plate in turn is connected to corresponding suitable rods which are transverse to each other and which are driven obliquely into the ground.

The invention is not limited to obliquely projecting into the ground elements such as screw or threaded rods or rods, but it can also be provided that said rods are driven or screwed vertically into the ground.

With the attachment of an additional, in the outer diameter much larger stabilizer base plate of the significant advantage is achieved that now a much higher bending moment load on the existing ground anchor can be transferred to the surrounding soil, because corresponding bending or torsional forces now in their diameter much larger and the ground anchor around comprehensive stabilizer base plate absorbs the corresponding forces.

This has the further advantage that the pull-out forces are substantially increased, because a corresponding tensile force is transmitted to the stabilizer base plate on the large base plate and anchored in the base plate rods low on the ground.

The shape of the stabilizer base plate surrounding the conventional ground anchor can be varied within free limits. It is preferably formed as a disc. However, the invention is not limited thereto.

Instead of training as a disc, the stabilizer base plate may also be oval, rectangular or square. It also does not need to be smooth, but may have additional tips or protrusions on its underside that allow additional burial into the ground.

Furthermore, their top must not be smooth. The top is adapted to the existing circumstances. It is important that about evenly distributed on the circumference in the stabilizer base plate recesses are provided, which are formed either as round or oval recesses or - in a further embodiment - as screw holes.

Through these recesses either round bars can be beaten, which engage so immediately in the form of herring in the ground.

However, instead of the rods, threaded rods can either be hammered or screwed into the ground.

If the recesses in the stabilizer base plate are formed as threaded bores, an additional strength results from the fact that the threaded rods are screwed into the thread of the recess and are subsequently screwed by means of threaded engagement in the ground.

In a preferred embodiment of the present invention, it is preferred if an additional adapter is arranged between the conventional ground anchoring and the stabilizer base plate according to the invention.

This adapter is intended on the one hand to provide the positive connection with the conventional, existing ground anchor and on the other hand, the positive connection of the adapter embracing stabilizer base plate.

The adapter can take a variety of forms. Its inner circumference depends on the shape of the conventional ground anchor.

The adapter can be connected to the ground anchor in various ways. On the one hand this is done by clamping means, on the other hand, screw elements can be used. It is also possible to press the adapter with the conventional ground anchor or screw. The outer circumference of the adapter is adapted to the inner circumference of the stabilizer base plate. In this case, in turn, a screw engagement can be provided or else a press fit or a clearance fit.

Likewise, corresponding clamping elements can be arranged in this transition region, which ensure a non-positive and positive connection of the inner circumference of the stabilizer base plate to the outer circumference of the adapter.

As already stated, it is not necessary to form the adapter as a disk. It can also be designed as a rectangular plate, as a square plate or as an oval plate.

Likewise, it can be provided that both the adapter and the stabilizer base plate surrounding the adapter are designed in at least two parts.

The two-part design is particularly suitable and intended for retrofitting to a conventional ground anchor.

It therefore requires no further assembly work, because the two mutually associated halves of adapter and stabilizer base plate are simply placed against each other placed on the ground and are connected to each other by appropriate transverse clamping elements frictionally. In this way, the ground anchor or ground anchor received in the interior of the adapter is positively and positively clamped by the adapter and the stabilizer base plate surrounding the adapter.

In another embodiment, it may also be provided that the adapter is omitted and the stabilizer base plate is connected directly with clamping elements (preferably screw spindles) with the ground-side ground anchor. In particular, it is preferred if a plurality of evenly distributed around the circumference arranged screw spindles have inwardly directed jaws, which create a positive and positive fit on the outer circumference of the ground anchor.

After each screw spindle is individually adjustable, an adjustment is possible. It is therefore an adjusting device, so that with the help of the setting of the screw spindles, the inclination of the ground anchor and thus possibly connected flagpole or traffic mast is infinitely adjustable.

In one embodiment of the invention, it is provided that the stabilizer base plate has a radially extending slot, so that this slot is adapted to push the stabilizer base laterally against the ground anchor and then with the aid of clamping elements to narrow the slot so that also a clamping connection between the stabilizer base plate and the ground anchor is given.

In another embodiment, it is provided that the stabilizer base plate is formed in two parts and the two parts are connected on one side with a pivot joint.

Again, a subsequent mounting on a conventional, already existing ground anchor possible because this simply the two parts of the base plate must be opened, they are then led around in the unfolded state around the ground anchor and folded back together and braced so that the ground anchor in Area of an inner recess of the stabilizer base plate is clamped and positively received.

The subject of the present invention results not only from the subject matter of the individual claims, but also from the combination of the individual claims with each other.

All information and features disclosed in the documents, including the abstract, in particular the spatial ones shown in the drawings Training, are claimed as essential to the invention, as far as they are new individually or in combination over the prior art.

In the following, the invention will be explained in more detail with reference to several Ausfϋhrungswege performing drawings. Here are from the drawings and their description further features essential to the invention and advantages of the invention.

Show it:

Figure 1: a first embodiment of a stabilizer device according to the invention

Figure 2: the top view of the arrangement of Figure 2 with representation of two different embodiments

Figure 3: a third embodiment of a stabilizer

Figure 4: a fourth embodiment of a stabilizer, which is designed as an adjusting device

Figure 5: a fifth embodiment of a stabilizer

Figure 6: a sixth embodiment of a stabilizer

It should be noted in advance that the embodiments described in the following drawings can also be combined with one another as desired, so that the description of a single exemplary embodiment also applies to the other exemplary embodiments, as far as they can be combined with one another.

FIG. 1 shows by way of example that on a conventional ground anchor 1, which is designed, for example, as a peg and has a head 2, whose screw member 3 is screwed into the ground, an adapter 5 is attached.

The head 2 of the ground anchor 1 may be extended, for example in the form of a mast 4 upwards. The mast 4 may be a flagpole or a traffic pole. Likewise, this may be a support column for a carport or for another structure.

In order to improve now the tipping stability and the pull-out strength of a conventional ground anchor 1, the invention provides that the ground anchor

1 is screwed through the inner recess of an adapter 5, wherein the adapter 5 may be formed, for example, as a disc body.

According to the invention it is further provided that the adapter 5 is positively and positively received with its outer periphery in the inner periphery of an associated stabilizer base plate 10.

On the stabilizer base plate 10 evenly distributed around the circumference recesses 9 are arranged, which may be formed either as through-openings or as threaded openings.

Through the recesses 9 in this case engage any number of rods 11, 12 therethrough, either round rods 12 or threaded rods 11 are present, whereby both rods 11, 12 can be used together on a stabilizer base plate 10.

The head 2 of the ground anchor 1 is screwed or pressed through a correspondingly suitable recess in the adapter 5. Here is the figure

2 two different embodiments. The left side of Figure 2 shows that an internal thread is provided on the adapter 5a, which is designed as a screw adapter.

The screw 3 has a corresponding external thread, so that the two types of threads are engaged with each other. The right side of Figure 2 shows that instead of the thread 7 and a fit 8 may be present, ie a simple cylindrical bore through which the screw 3 of the ground anchor 1 passes through and the head 2 hereby applies to the surface of the adapter 5.

In the same way, Figure 2 shows the transition between the outer circumference of the adapter 5 in the direction of the inner circumference of the stabilizer base plate 10 in two different embodiments.

On the left side of Figure 2 it is shown that the outer circumference of the adapter 5 is formed as an external thread 6, which is screwed into an associated thread on the inner periphery of the stabilizer base plate 10.

On the other hand, the right representation in Figure 2 shows that instead of the external thread 6 and a simple fit 8, z. B. may be provided as a cylinder liner, on which the smooth and cylindrical inner circumference of the stabilizer base plate 10 is placed and pressed.

FIGS. 1 and 2 show in an impressive manner that the tilting forces and the pull-out forces are thereby improved by arranging an adapter 5 and a stabilizer base plate 10 which is substantially larger in diameter.

This can not be subsequently stabilized in the ground anchored ground anchor 1 stabilized.

FIG. 3 shows a two-part construction of a stabilizer base plate 10 in conjunction with a two-part design of an adapter 5.

The two parts are therefore formed in half with respect to a parting line to each other, and the two halves are non-positively bolted together by corresponding clamping elements 14. Such clamping elements 14 are in particular threaded spindles or threaded screws.

The attachment of the stabilizer base plate 10 in the ground takes place in the same manner as described with reference to Figures 1 and 2.

FIG. 4 shows that either a one-piece or a two-part stabilizer base plate 10 can be present and that a number of radially extending clamping elements 15 are arranged on the stabilizer base plate, which are preferably designed as threaded spindles.

Each threaded spindle carries at its radially inwardly directed end a claw 16, which bears non-positively and positively on the outer periphery of the ground anchor 1.

By individual adjustment of the respective clamping element 15 thus an adjusting device is realized, so that the ground anchor 1 and a mast 4 attached thereto can be freely aligned, according to the setting of the clamping elements 15th

Figures 5 and 6 show again related embodiments, wherein in the embodiment of Figure 5 can be seen that both the adapter 5 and the stabilizer base plate 10 are provided with a transverse slot 18, so that the entire arrangement of the one side of the Ground anchor 1 can be pushed, under the head 2 of the ground anchor 1, which is thus set on the inner circumference of the cross section 18 in the region of the adapter 5.

The transverse slot 18 is again closed and clamped together by one or more clamping elements 14, so that a high-load-transmitting connection between the ground anchor 1 and the surrounding adapter 5 and the stabilizer base plate 10 is given. FIG. 6 shows that the parts shown in FIG. 5 can also be formed in half, with the two halves, however, being pivotably connected together by means of a joint 17.

The thus formed transverse slot 13 can in turn be closed and clamped non-positively by the previously described clamping elements 14.

Such a hinge 17, which connects the two parts pivotally with each other, can also be used in the embodiment of Figure 3.
