Description

The present invention relates to a stabilization device for position stabilization of a rod-shaped article or a ground anchor, a method for producing a stabilization device and a driving tool for driving a stabilization device into the ground.

It is well known to collect rod-shaped objects, such as posts, poles or masts in the ground. Due to weather conditions, however, these loosen over time.

To stabilize such a rod-shaped article, e.g. To make a post, in the simplest case this is embedded in the ground in the driven state, which is disadvantageous from an environmental point of view. In addition, cast-in posts are difficult to remove from the ground again. Another possibility is to densify posts by stamping filler or hammering wood wedges for position stabilization.

A disadvantage of the ramming and compacting of filling material is that the soil around the post reduces the water permeability, which leads to the accumulation of moisture .. When driving wood wedges has the disadvantage that an accurate positioning of the vertical position of the post can be made only insufficient and that the wood material has only a limited life.

In order to overcome these disadvantages, ground anchors for receiving rod-shaped objects are generally known. Such a ground anchor, which is widely used, is for example from the European patent EP 0 243 376 B1 known.

Even with the use of ground anchors, the problem may arise that a loosening of the ground anchor with it picked up post by severe weather or vandalism can occur through leverage over the post.

The invention is therefore an object of the invention to provide a stabilizing device which is simple in construction and in the ground driven state has a long life, to provide a method for producing a stabilizing device and to provide a driving tool for a stabilizing device.

This object is achieved by the features specified in claim 1, 13 and 14.

A stabilizing device formed according to the invention can easily stabilize a rod-shaped object or a ground anchor in the ground both subsequently in the loosened state and during the driving operation of the rod-shaped object or ground anchor in its position over a longer period of time. Since the base part is formed inclined to the support member or the support area and the base portion is formed wider than the support member or the support area, there is a large area support of the rod-shaped object or ground anchor in the ground, so that a secure position even under the influence of weather or mechanical forces can be guaranteed. By a distance between the base part of the stabilizing device and the rod-shaped object or ground anchor moisture in this area can be discharged into the soil.

Further developments of the invention are specified in the subclaims.

In one embodiment of the invention, I taper a portion of the support member or support region continuously from an upper edge to the lower edge. Thereby, the stabilizing device can be easily applied to the rod-shaped object or ground anchor and driven, wherein during the driving operation, the stabilization device uniformly slides along the rod-shaped object or ground anchor along.

In a further embodiment of the invention, the base part has the shape of a semicircle or a circle segment or has a V-shape. A stabilizing device with such a base part can be produced easily.

In a further embodiment of the invention, at least the base part is made of a material with rigid elastic properties. This has the advantage that the outer regions of the base part rest under a bias on the rod-shaped object or ground anchor and thus ensure a good position stabilization over a long period of time.

If an upper edge of the support member or support portion protrudes upward over an upper edge of the base member, in another embodiment of the invention has the advantage that when driving the stabilizing device, the risk of damage to the base member is largely avoided.

In a further embodiment according to the invention, in which the support region is produced by forming the base part, there is the advantage of simple production with low material expenditure.

In a further embodiment according to the invention, the base part and / or the support part and / or the support region have openings. This has the advantage that root braid can grow through these breakthroughs, which leads to a further solidification of the stabilization device in the ground.

If according to a further embodiment of the invention, the lower edge of the base part is curved or pointed in the central region, the driving of the stabilizing device is facilitated in the soil.

In a further embodiment of the invention, the stabilization device is divided into two parts, each of which has a base part and a support part. This has the advantage of easier production.

If a plurality of supporting parts or supporting regions are used in another stabilizing device according to the invention, the stability behavior can be further improved.

According to a further embodiment of the invention, since the stabilizing device is made of metal or plastic, the life span may be reduced compared with e.g. made of wood existing wedges can be improved.

If according to a further embodiment of the invention, the end face of the support member or support region is convex or wavy, the sliding effect when driving into the soil can be further improved.

According to a method of the invention, the stabilizing device is made by cutting a metal sheet and forming the metal sheet into an arcuate or wedge shape. Simultaneously with the forming process or chronologically following a bead is pressed into the base part, which serves as a support area. As a result, a particularly simple and material-saving production possibility of the stabilization device is given.

An inventive driving tool is in the form of a hollow cylinder half formed with a circular arc-shaped inner wall and a circular arc-shaped outer wall. As a result, the process of driving a stabilizing device is facilitated. To further improve the handling, the driving tool on a handle.

In a further embodiment, a driving tool according to the invention has two hollow-cylinder halves, which are connected to one another via a hinge. This allows the driving tool to be positioned around the rod-shaped object or ground anchor. In order to further improve the handling of the driving operation, a vertically extending rod is disposed on each hollow cylinder half to which a handle is mounted.

Fig. 1 shows a perspective view of a stabilization device 10, which has a base part 12 and a support member 14. The base part 12 is in the form of a half tube formed with a diameter D, a height H and a wall thickness W. Along one in the direction of Height H extending center line M, the support member 14 is arranged with a length L, a width BS and a depth T at an upper edge 12a of the base member 12. The support member 14 extends from the upper edge 12a of the base member 12 to a lower edge 12b of Base part 12, wherein the depth T tapers continuously from the upper edge 12a in the direction of the lower edge 12b. The diameter D of the base part 12 and the width BS of the support part 14 extend in the width direction B.

In the embodiment shown, the support member 14 terminates at a predetermined distance from the lower edge 12b. In another embodiment, not shown, the support member 14 extends over the entire height H of the base member 12. In another embodiment, not shown, the support member 14 starts at a predetermined distance from the upper edge 12a.

In the preferred embodiment of Fig. 1 the diameter D is 56mm, the height H 220mm, the wall thickness of the base 12 12mm, the length L of the support member 14 180mm, the depth T of the support member 14 at the top edge 12 18mm and the thickness D of the support member 14 5mm. These dimensions refer to the use for stabilizing the position of a post with a diameter of 60mm or a ground anchor with a diameter of 67mm. The dimensions mentioned are to be interpreted as illustrative and not restrictive.

The stabilizing device 10, in particular the base part 12, consists of a rigid elastic material, e.g. rigid elastic polypropylene. The term "rigid elastic" is to be understood as meaning that the material has the property that the base part 12 is deformed on both sides in the upper region under a certain expenditure of force, e.g. of at least a few Newton, preferably in a range above 20N, can be spread in the width direction B and returns to its initial position after discharge.

In the embodiment shown, the base part 12 and the support part 14 are integrally formed and e.g. produced by an injection molding process.

The material of the stabilization device 10 is not limited to plastic.

In other embodiments, the stabilizer 10 is made of a metal material, e.g. Steel or aluminum. In the use of steel, the base member 12 and the support member 14 in one embodiment are fabricated as separate parts and added to the stabilizer 10 by a suitable joining method, such as a method described in US Pat. Welding or brazing connected together. To improve corrosion resistance, the steel stabilizer 10 is galvanized or otherwise corrosion protected in other known ways.

For producing the stabilizing device 10 from an aluminum material, a die-casting method can be used.

In another modified embodiment, the base part 12 and the support part 14 are made of different materials and are connected together by a suitable joining method.

Fig. 2 shows a perspective view of an embodiment of a stabilizing device 20, which is similar to the embodiment of Fig. 1 is formed and has a base part 22 and a support member 24. The base member 22 has the shape of a circle segment unlike the first embodiment explained. The support member 24 is also arranged along a center line M extending in the direction of the height H, the depth T of which tapers continuously from an upper edge 22a of the base part 20 to a lower edge 22b of the base part 20.

In Fig. 3 is a modified embodiment of Fig. 2 shown. The stabilizer 20A is formed in two parts 20A1, 20A2, the part 20A1 having a first base part 22A1 and a first support part 24A1 and the part 20A2 having a second base part 22A2 and a second support part 24A2.

The first support part 24A1 tapers from an upper edge 22A1a of the base part 22A1 toward a lower edge 22A1b. Likewise, the second support member 24A2 tapers from an upper edge 22A2a of the base member 22A2 toward a lower edge 22A2b

The two parts 20A1, 20A2 are removed by a suitable joining method, such as Gluing in the use of plastic, or welding in the use of steel, along the outer surfaces of the support members 24A1, 24A2 connected to each other.

In another embodiment, the two parts 20A1, 20A2 remain separate and are placed against each other on the outer surfaces of the support parts 24A1, 24A2 together in the soil E (see Fig. 5 ).

This embodiment is advantageous in terms of ease of manufacture, especially when the stabilizing device is made of sheet steel.

Fig. 4 shows a stabilizing device 30 with a base portion 32 having a molded support portion 34 in the form of a bead whose depth T tapers from an upper edge 32a toward the lower edge 32b, so that it has a wedge shape.

The stabilizing device 30 is preferably made of steel, wherein the molded support portion 34 is made by a forming process. In another embodiment, the stabilizer 300 is made by a primary molding process

In another embodiment, the stabilizing device 30 is made of plastic and is manufactured by injection molding or a hot forming process.

Fig. 5 shows two driven into the soil E stabilization devices 10, which include a post 100 on its outer periphery and make a position stabilization of the same.

In the driven state of the stabilizer 10 is therefore due to the rigid elastic material properties, the base member 12 under a bias on both sides of the post 100, so that a good positional stabilization of the post 100 can be achieved over a long period.

In Fig. 6 a driving tool 50 is shown, which is in the form of a two halves 52, 54 existing hollow cylinder with a circular arc-shaped inner wall and a circular arc-shaped outer wall, wherein the hollow cylinder halves 52, 54 are pivotally connected to each other via a hinge 55. Each hollow cylinder half 52; 54 is provided with a bow-shaped handle 56, which ensures easy handling of the driving tool 50.

The hinge 55 offers the possibility of laying the driving tool 50 around the post 100 in a simple manner and the stabilizing device 10; 20; 20A; 30 into the ground E to march. The driving tool 50 has a predetermined mass, e.g. 5kg or higher to make the drive effective.

In a modified embodiment, as in Fig. 6 shown with dashed lines, on each hollow cylinder half 52; 54 a vertically extending in the direction of the height H extending bar 58, on which the bow-shaped handle 56 is mounted. As a result, the handling of the driving tool 50 is improved so that a standing user can work ergonomically with the driving tool 50.

In another embodiment, a not shown driving tool is used, which has only a hollow cylinder half, so that a hinge is eliminated. In a modification of the embodiments, the hinge is easily separable, so that a hollow cylinder half is posted as needed and is used only for driving alone.

As in Fig. 5 can be shown, two, the post 100 comprehensive stabilization devices 10; 30 be driven into the soil E. Depending on the size of the circle segment, it is also possible to use 3, 4 or more stabilizing devices 20; 30 into the earth E around the circumference of the post 100 or a ground anchor, not shown, are driven into the earth E to stabilize the post 100 or the ground anchor around the circumference in its vertical position.

Furthermore, there is the possibility of only one stabilizing device 10; 20; 20A; 30 for stabilizing the position of an inclined post 100 or ground anchor in the soil E collect. In addition, two or more stabilizing devices 10; 20; 30 in a row be driven into the soil E.

When using the stabilization device 10; 20; 20A; In a region near the surface of the earth E, the rod-shaped article or ground anchor is stably supported in the lateral direction. Since a cavity is formed between the rod-shaped object or ground anchor, unimpeded drainage of accumulating moisture can be ensured. In one embodiment, the cavity is filled with a water-permeable granules. In certain applications, hardening material, such as mortar, is introduced into the cavity.

When using at least one stabilizing device 10; 20; 20A; 30 for the position stabilization of a ground anchor, as he eg from the EP 0 243 376 B1 is known, the at least one stabilizing device 10; 20; 20A; 30 are used in a loose ground anchor, or the at least one stabilizing device 10; 20; 20A; 30 can be rammed into the soil E before driving the ground anchor. Furthermore, it is possible to pull a loose ground anchor from the earth E, the at least one stabilizing device 10; 20; 20A; 30 in the soil E and then collect the ground anchor in the soil E.

In addition, the at least one stabilizing device 10; 20; 20A; 30 be attached to the rod-shaped object or ground anchor before driving into the soil E. The attachment is made in the preferred embodiment by means of cable ties or tape.

Although in described embodiments, the entire stabilization device 10; 20; 20A; 30 consists of a rigid elastic material, consists in a modified embodiment in which the base part 12; 22; 22A1, 22A2 and the support member 14; 24; 24A1, 24A2 made separately and then firmly connected to each other, the possibility of only the base member 12; 2; 22A1, 22A2 produce a rigid elastic material.

In another modified embodiment, the stabilization device 10; 20; 20A; 30; 40 or at least the base part 12; 22; 22A1, 22A2, 32; 42 made of a plastically deformable material.

The stabilization device 10; 20; 20A; 30; In the preferred embodiments, 40 is plastic, such as polypropylene, or metal, such as polypropylene. Sheet steel. However, the invention is not limited thereto, but any other material may be used, which is suitable.

Further modifications of or modifications of the illustrated embodiments are possible.

In an in Fig. 7 embodiment shown based on the embodiment of Fig. 2 the base part 22 has a V-shape in cross-section instead of the shape of a circle segment.

In one embodiment of Fig. 8 the base part 22 has apertures 26. This has the advantage that root braid can grow through these openings 26, which leads to a further solidification of the stabilization device 20 in the soil E. The openings 26 may be circular, square, rectangular, oval or have another geometric shape.

In a modified embodiment, the support member 24 has openings 26.

In the in Fig. 9 In the embodiment shown, the lower edge 22b is arched or pointed in the central region in order to facilitate the driving-in process.

Fig. 10 shows an embodiment in which the support member 24 has no uniform wedge shape, but is convex curved. In a modified embodiment, the support member 24 is formed wave-shaped at its end face, wherein the amplitudes of the waves decrease in size to the lower edge 22b. Also by these measures the driving operation is facilitated.

Fig. 11 shows an embodiment in which an upper edge 24a of the support member 24 is disposed higher than the upper edge 22a of the base part 22a, that is, the upper edge 24a of the support member 24 protrudes beyond the upper edge 22a of the base part 22a. Thus, the risk of damage to the base member 22 is largely avoided when driving the stabilizing device.

Fig. 12 shows an embodiment of a stabilization device 40 with a base part 42, in which a vertical row of a plurality of support portions 44a, 44b, 44c are formed along a center line M of the base part 32 by punching and bending. The height HB of the support area 44a; 44b; 44c decreases from the upper edge 42a of the base 42 to the lower edge 42b of the base 42. The support portions 44a, 44b, 44c may have a convex curvature.

All embodiments are dimensioned such that the curvature of the half tube, the base part in the form of a circle segment or the base part in V-shape is adapted to the diameter or width dimension of the rod-shaped object or ground anchor.

Although only a vertically extending support portion, a vertically extending support portion or a vertical row of support portions are shown in the illustrated embodiments, a plurality of vertically extending support members, support portions or rows of support portions are also arranged in modified embodiments. The support parts or support areas are arranged parallel to each other or extending at an angle to each other.

Preferably, the diameter D of the base part is smaller than the diameter of the rod-shaped object or ground anchor, so that they are spread out when it is applied to the rod-shaped object or ground anchor and when driving. This results in a particularly good positional stability of the rod-shaped object or ground anchor.

The in the FIGS. 7 to 12 disclosed features can also be combined for the embodiments of the other figures. It is expressly stated that similar to the embodiment of Fig. 11 also in the embodiment of Fig. 4 the support region 34 can be made higher than the upper edge 32 a of the base part 32.

Other hybrid forms between the described embodiments, such as the others in the FIGS. 7 to 12 illustrated features and their modifications with the embodiments of Fig. 1 to 4 and their modifications are therefore to be regarded as expressly belonging to the scope of the present invention.
