wherein the dismantling tool (1) comprises a dismantling bracket (20) which is formed in one piece from an upper horizontal strut (4), a lower horizontal strut (5) and a vertical strut (6),
wherein the struts (4, 5, 6) of the dismantling bracket (20) are arranged in a C-shape, so that the dismantling bracket (1) can be arranged around the shaped body (11, 12, 13) in such a way that the shaped body (11, 12, 13 ) comes to lie between the upper horizontal strut (4) and the lower horizontal strut (5),
so that the dismantling tool can be raised, as a result of which the shaped body is at least partially lifted out of the ground.

Description

The present invention relates to a dismantling tool with which, in particular, borders of graves, curbs and paving stones can be dismantled.

technical field

In gardening and landscaping, partial areas are often separated from one another by means of enclosures. Graves are provided with a border, which usually delimits the grave all around. Furthermore, z. B. also terraces or paved areas separated by boundary stones from the surrounding lawn or beds opposite to adjacent areas. In addition to the optical effect of borders or enclosures, the boundary stones hold back the often loose soil of graves or beds. Enclosures or enclosures are often formed by means of elongate stones, some of which protrude above the ground and are either loosely buried along their underside, or firmly concreted onto a foundation. Grave borders are most often formed with several stones fixed on a common foundation. The terms enclosure, boundary and enclosure are usually not differentiated and used synonymously.

Elongated boundary stones are also used in road construction to separate different traffic areas. Probably the best-known example is the curb that separates sidewalks from driveways. Curbs are also called curbs or curbs in many places.

While the individual stones can be brought and arranged separately when separating areas formed by stones when assembling, this is no longer possible when dismantling, since the individual stones together with their foundation or together with the neighboring stones form a connected structure, which also largely dug or buried. Unlike assembly, dismantling therefore requires the use of heavy equipment or a great deal of perseverance when excavating.

State of the art

With regard to edging graves, borders in gardening and landscaping and when laying sidewalks with curbs, the state of the art can be divided into the areas of "transport and assembly" and "dismantling".

A number of solutions are known from the prior art for the “transport and assembly” area.

From the DE 43 03 944 A1 (Publication date: August 11, 1994, inventor: Probst, Greif und Fördertechnik GmbH) is a lifting device for laying curbs known, with the curbs can be spent hanging on a boom to a desired installation site and can be sold at the installation site. The curbs are gripped from the top.

In the DE 83 03 676 U1 (Announcement date: June 16, 1983, inventor: Konrad Wolfgang Maier) a crane and transport device for transporting gravestones and gravestone slabs is specified, which has a chassis and a crane, the crane with a trolley can be moved along the direction of travel to the To transport crane hooks with the tombstone or stone over a desired location. The load is gripped from the top with a crane hook.

From the DE 10 2012 112 757 A1 (Publication date: July 10, 2014, inventor: Gerhard Greßbach) a curb lifter is known, which is designed in several pieces and in which curbs can be clamped between a connecting element and a hold-down device. The connecting element grips the curb from the underside. Lifting is done by a handle placed on the top side opposite the connecting element.

the DE 20 2007 002 564 U1 (Announcement date: July 12, 2007, inventor: Dieter Roßner) specifies a device for holding and lifting incorrectly seated or damaged boundary stones, in particular curbs, in which two clamps grip a boundary stone from the top and the stone is raised via a threaded connection , and can be spent on a chassis.

From the DE 10 2016 120 030 A1 (Publication date: December 7th, 2017, inventor: Herbert Hartnagel) a lifting device for a load is known, in particular for a curb, in which the load can be enclosed between two underpinning struts and a safety device and lifted using a transport hook. To lift the load, the lower braces are placed under the load, much like the forks of an industrial truck, whereupon the safety device is placed on top of the load to grip the load.

While the publications mentioned above cover the area of "transport and assembly" concern, it is known from the general prior art to dismantle enclosures using spades and hoes. The borders of graves are dismantled, for example, by driving a pickaxe under the construction of foundation and border stone and then levering it out manually. It is often no longer possible to grasp the edging stone from above after assembly, which is due, among other things, to the increased mass of several connected edging stones and their foundations.

The aforementioned documents are considered to be incorporated in their entirety in the present description of the invention by their naming. This is to avoid re-discussing, rather than by reference, well-known relationships between bordering and bordering material and equipment used to transport or erect the material, and between the installation and removal of bordering, curbs and bordering in general to the references or reference as also defined for the present invention.

task

While the state of the art provides suitable means for transporting and assembling grave edging stones, curbs or, generally speaking, elongated shaped bodies that are at least partially embedded in the ground, suitable means for dismantling the structures mentioned in gardening and landscaping are almost unknown. The object of this invention is therefore to specify an improved tool for dismantling borders, curbs or, to put it in general terms, elongated shaped bodies that are at least partially embedded in the ground.

In other words, it would be desirable to be as easy as possible to dismantle edgings from graves, curbs and borders in gardening and landscaping, since dismantling, unlike assembly, has hitherto been carried out predominantly with human power and increased workload.

invention description

The object of the invention is achieved by a dismantling tool according to claim 1.

Advantageous developments of the dismantling tool can be found in the dependent claims.

In the following, borders of graves, kerbstones, boundary stones, border stones and other elongated boundary bodies that separate two areas of an area from one another are subsumed under the generic term “form body”. Shaped bodies can consist of different materials, in particular natural stone, concrete, wood or metals. A shaped body can also consist of several parts, in particular a foundation with a boundary stone resting on it or a foundation with several boundary stones arranged one behind the other and resting on it.

According to the invention, a dismantling tool is provided for dismantling molded bodies that are at least partially embedded in a substrate, the dismantling tool comprising a dismantling bracket which is formed in one piece from an upper horizontal strut, a lower horizontal strut and a vertical strut, the struts of the dismantling bracket being arranged in a C-shape, so that the dismantling bracket can be arranged around the shaped body in such a way that the shaped body comes to lie between the upper horizontal strut and the lower horizontal strut.

The bracket, which is produced in one piece from a continuous base material, thus has the shape of the letter C in its side view. Accordingly, a space for later accommodating a shaped body is bordered by an upper horizontal strut, a lower horizontal strut and a vertical strut and is open in one direction so that the dismantling bracket can be arranged around the shaped body. Steel and reinforced plastics are particularly suitable as the base material. In particular, the dismantling bracket of the dismantling tool can be made of rebar steel, as is used to reinforce concrete structures. This base material is easy to process, inexpensive and readily available, but at the same time, if a suitable material thickness is selected, it is stable enough to detach the molded body from its assembly position without bending or breaking itself.

In their usual position of use, the horizontal struts lie essentially within a plane essentially parallel to the surface of the earth. Likewise, the vertical strut runs essentially vertically to the surface of the earth. Alternatively, the struts or individual struts, ie the upper and lower horizontal struts and the vertical strut, can also form an angle to the earth's surface. It is particularly advantageous if the lower horizontal strut forms an acute angle to the vertically running vertical strut, so that molded bodies are secured against slipping out of the C-shape during disassembly in the disassembly bracket.

In the context of this invention, one-piece means that the struts are either made from a continuous material, for example from a continuous rebar, or that the struts were produced by complete material connection or in a joint casting. The one-piece design offers advantages in the production of the dismantling tool, as will be described in relation to this method, but the one-piece design also offers very high strength, since there are no connection areas, for example spot welds, which often represent weak points.

According to a preferred embodiment, a loop is arranged on the upper horizontal strut, by means of which the dismantling tool can be lifted for dismantling the shaped body.

The loop on the upper horizontal strut can be designed as an eyelet for a crane hook, as a belt loop or as a handle. It points away from the upper horizontal strut in the vertical direction and is designed with regard to its material thickness in such a way that the shaped body can also be lifted out of a concreted structure of several shaped bodies.

The loop can also be designed as a handle, so that operators can manually pull out or lever out the disassembly tool if the assembly situation of the shaped body allows it.

Although the loop is usually present on the upper horizontal strut, it is arranged over the middle of the lower horizontal strut, so that the shaped body is kept in balance within the dismantling bracket and no torques are generated. Alternatively, the loop can be arranged off-centre, so that torques can be deliberately generated, which have a supporting effect when the shaped body is detached from its structure. For this purpose, the loop can be arranged, for example, in the area of the free end of the upper horizontal strut.

In other words, the dismantling tool according to the invention is a material shaped into a C-frame, preferably round material, which has a strength that makes it possible to use the dismantling tool to lift shaped bodies, such as grave edging stones, that are partially embedded in the ground can become. Unlike assembly, which is about the aesthetically pleasing, precise laying, disassembly is about the easy and quick levering out of shaped bodies.

The use of the dismantling tool according to the invention is explained using the example of a grave that is to be cleared and in which the fence has to be removed. The procedure is as follows: First, the lower horizontal strut of the C-shaped dismantling bracket is pushed under the enclosure from the side of the grave with its free end in front. Pushing in from the side of the grave has the advantage that the soil inside the grave is often looser and therefore more easily accessible than the outside of the subsoil in which the grave edging is embedded. After insertion, the lower horizontal strut is located under the grave border and, if present, also under the foundation of the grave border. In other words, the dismantling bracket encloses the frame in cross section from three sides, with the lower and upper horizontal brace and the vertical brace. The dismantling tool is then pulled upwards, which pulls up the bezel and thus releases it. For example, a tripod with a block and tackle, a crane or, if necessary, purely human strength can be used to pull it up. When the dismantling tool is moved upwards, the fence or at least a part of the fence is released upwards from the ground and can then be easily transported away. If there are several sections of an enclosure, the process is repeated accordingly.

The clear distance between the upper and the lower horizontal strut is advantageously greater than 45 cm, in particular 60 cm. The length of the upper or lower horizontal strut, measured from the side of the vertical strut pointing towards the free ends, is advantageously more than 30 cm, in particular 50 cm. The upper and lower horizontal struts can be of different lengths, in particular such that the lower horizontal strut is longer to exert a torque.

Advantageous refinements and developments are set out below, which, viewed individually, both individually and in combination, can also reveal inventive aspects.

In an alternative embodiment, bracing angles are arranged between the upper horizontal strut and the vertical strut and between the lower horizontal strut and the vertical strut, which increase the dimensional stability of the C-shaped dismantling bracket.

The bending elasticity in the vertical direction is accordingly reduced by means of the stiffening angle, so that forces exerted when lifting or levering the dismantling bracket are directed towards the dismantling moldings are transferred. The stiffening brackets can be welded to the dismantling bracket. The stiffening angles can have a flat shape or alternatively be designed as rods.

In an alternative embodiment, the lower horizontal strut of the dismantling bracket is pointed on its side pointing towards the open side of the C-profile of the dismantling bracket. A pointed free end of the lower horizontal strut is advantageous when pushing it into the ground.

The open side is the free end of the horizontal strut, which does not merge into the adjacent vertical strut. Sharpening can be done by removing material from the lower horizontal strut in a rotationally symmetrical manner or by cutting off part of the strut at an acute angle. The tip at the free end of the lower horizontal strut enables the lower horizontal strut to be driven into the ground below the shaped body in a simple and less forceful manner.

Alternatively or additionally, the vertical strut can be provided with a head surface in the area of the transition to the lower horizontal strut, via which the dismantling bracket can be driven into the ground using a hammer. The head surface sits on the vertical strut in the area of the longitudinal axis of the lower horizontal strut, so that the direction of force of the hammer blows acts in the direction of the longitudinal axis of the lower horizontal strut.

In an alternative embodiment, the lower horizontal strut is longer than the upper horizontal strut.

Accordingly, the free end of the lower horizontal strut, pointed or blunt, protrudes beyond the free end of the upper horizontal strut, so that the C-shape is not symmetrical with respect to the horizontal struts. Conversely, with a longer lower horizontal strut, which can be used as a lever arm, a greater torque can be applied with the same force, so that shaped bodies can be easily released.

In an alternative embodiment, the upper horizontal strut has a vertically running extension at its free end, which is shorter than the vertical strut and is formed in one piece from the same basic material as the rest of the dismantling bracket.

Accordingly, the free end of the upper horizontal strut is bent in the direction of the lower horizontal strut, so that the extension runs vertically or at least essentially vertically. One advantage of the extension is that a loop designed as a sling cannot slip over the free end of the upper horizontal strut, which increases operational safety. Also, the tab helps prevent the enclosed enclosure from slipping out when the dismantling bracket is lifted.

The term vertical, as previously defined for vertical brace and horizontal braces, means that the longitudinal axis of the section referred to is in a direction towards the surface of the earth. For this purpose, the section, for example the appendage, need not be parallel to the vector of gravity, but an angle of, for example, 45 degrees between the section and the earth's surface would also be referred to as vertical.

In an alternative embodiment, the upper horizontal brace has a plurality of loops spaced along the longitudinal axis of the upper horizontal brace.

This enables the lifting device, for example the block and tackle or the crane, to be able to be gripped at a desired point on the dismantling bracket. If you want no or only low torques to be generated, you choose a loop that lies as precisely as possible over the shaped body along the longitudinal axis of the upper horizontal strut. Torques can consequently be generated if a loop is selected which is offset in the horizontal direction to the shaped body.

Using a sling for lifting has the advantage that the point of application of the lifting force can be chosen at will along the longitudinal axis of the upper horizontal strut.

In an alternative embodiment, the dismantling bracket of the dismantling tool is formed from a reinforcing steel bar that has been bent into a C-profile, optionally with the extension described above.

Rebars are commonly available in diameters of 6, 8, 10, 12, 14, 16, 20, 25, 28, 32 and 40mm, with all diameters suitable for forming the dismantling tool. The selection of the diameter results, among other things, from the lifting force that is likely to be exerted and that is necessary to detach a shaped body from the ground or from the assembled assembly. In particular, a selection of several dismantling tools with different diameters can be provided, so that a road builder, gardener or landscaper can select the appropriate dismantling tool in each case.

Reinforcing steel is usually ribbed, which has the advantage that the shaped body slips less on the lower horizontal strut when it is lifted.

As an alternative to reinforcing bars, metal bars with any profile and cross-sectional shape can be used - not only round steel but also steel with other shapes such as e.g. B. square are well suited.

The invention also relates to a method for producing a dismantling tool, in particular a dismantling tool according to one of the aforementioned embodiments. According to the invention, a reinforcing steel bar is first provided, on which the lengths for the upper horizontal strut, for the vertical strut, for the lower horizontal strut and optionally for the extension are marked out starting from one end. The rebar is then bent in a bending machine at the marked points by a desired angle, which is usually around 90 degrees, so that a C-shaped dismantling bracket is created. Finally, if desired, one or more loops are placed on the top horizontal brace.

The loop can either be in the form of a sling and is then placed around the upper horizontal strut by means of a tie-stitch knot, or it can be in the form of an eyelet which can be welded to the upper horizontal strut.

For bending, the rebar can be heated locally at the bending points, which makes bending easier. Overbends, which allow for springback of the reinforcing steel bar after bending, can be calculated and carried out using standard methods depending on the choice of material.

In principle, all elongated profile bars made of metal can be used instead of rebars. However, particular attention is paid to the fatigue strength and bending elasticity of the selected material.

In an alternative embodiment of the manufacturing process, the free end of the lower horizontal strut is sharpened.

Sharpening can be done either by removing material radially symmetrically or by cutting off a section at an acute angle.

In an alternative embodiment of the manufacturing method, stiffening brackets are provided, the leg angles of which correspond to the bending angles of the dismantling bracket, which are arranged between the upper horizontal strut and the vertical strut and between the lower horizontal strut and the vertical strut.

character description

All representations are only to be understood as schematic; they are not true to scale, but an attempt was made to show the parts relevant to the invention particularly well.

1 shows the removal tool 1 in a side view. A vertical strut 6 is arranged between an upper horizontal strut 4 and a lower horizontal strut 5 . The struts 4, 5 and 6 together form a one-piece dismantling bracket 20 which has a C-shape. On the side of the upper horizontal strut 4 pointing vertically upwards there is a loop 2 by which the dismantling tool can be lifted.

2 shows an alternative embodiment of the dismantling tool 1 from 1 in a side view, wherein the upper horizontal strut 4 has an extension 7 which is formed at an approximately right angle to the upper horizontal strut 4. The extension has its longitudinal axis in the vertical direction and has a length that makes it impossible for a loop 2 designed as a sling to slip off. Alternatively or additionally, the length of the extension 7 can be dimensioned in such a way that operators can use the extension 7 as a handle for inserting the dismantling tool 1 under the mount. By grasping the extension 7, the operator pushes and pulls the lower horizontal strut 5 under the molding to be lifted off. The extension 7, the upper horizontal strut 4, the vertical strut 6 and the lower horizontal strut are formed in one piece from a continuous rod, for example a rebar, which was bent at the transitions.

In 2 a sling was used as the loop 2, which was placed around the upper horizontal strut 4 with an anchor stitch. Because of the extension, the sling cannot slip past the free end of the upper horizontal strut.

Despite the extension 7, the shape of the dismantling bracket 20 is made 2 referred to as C-shaped.

For the sake of simplicity, only almost right angles between the individual struts are shown in the figures, although other angles are conceivable and, as explained above in the description, are sometimes also technically advantageous.

3 shows an embodiment of the dismantling tool 1 in which stiffening angles 8 are arranged between the upper horizontal strut 4 and the vertical strut 6 and between the lower horizontal strut 5 and the vertical strut 6 . In addition, the lower horizontal strut 5 is longer than the upper horizontal strut 4 and is pointed.

The pointed area of the lower horizontal strut 4, the mandrel 3, makes it easier to drive the dismantling tool 1 into the ground below a shaped body to be dismantled.

Likewise, in 3 an alternative form of the loop 2 is shown, which is attached to the upper horizontal brace 4, for example by welding.

4 shows an embodiment of the dismantling tool 1 with a plurality of loops 2, which are arranged next to one another and spaced apart from one another on the upper horizontal strut 4 along the longitudinal axis of the upper horizontal strut 4.

5 shows the removal tool 1 3 in a side view during use for dismantling a shaped body 15, which comprises an enclosing stone 11 and a foundation stone 13, which are connected by means of a mortar 12. It should be noted that the illustration is not to scale.

The dismantling tool 1 was locked with the dismantling bracket 20 from an area rem soil 9 starting around the shaped body 15 arranged around that the lower horizontal strut 5 undermined the shaped body 15. On the other side of the loose soil 9 there is an area with firmer soil 10 into which the dismantling tool 1 could easily be driven due to the sharpened lower horizontal strut 5 .

Into the loop 2 of the removal tool 1 5 a pulley block or crane (not shown) can be hooked in, by means of which the dismantling tool 1 can be raised for dismantling the shaped body 15 . When it is lifted, the shaped body is transported above the ground so that it can then be transported away easily and conveniently.

In the 5 shown assembly situation of the shaped body 15 is typical for graves, which are to be resolved. There, the grave area enclosed by a fence is usually filled with loose soil, while the area around the grave, outside the fence, consists of mostly dense or compacted soil.

The design options shown in the individual figures can also be connected to one another in any form. In the figures, components that are the same or have the same effect are provided with the same reference symbols.
