Definitions

  • the invention relates to a device for anchoring tension members, such as ropes, chains or the like, in the grown or heaped up soil, consisting of an anchor body designed as a molded part with a small cross-sectional area relative to its length and from a longitudinally orientable on the anchor body and detachable therewith detachable driving and guide rod, the attachment point of the tension member being provided on the side of the anchor body at a distance from both ends thereof.
  • tension members such as ropes, chains or the like
  • ground or ground anchors Devices of the generic type are already known as so-called ground or ground anchors, as can be seen, for example, from US Pat. No. 972,306 and DE-PS 27 11 979.
  • an anchor body is used, which is cut at its rear end at an angle to the longitudinal axis and bent outward in a lip shape, and on the side opposite to the outward bend of the rear end between its center of gravity and its rear end the attachment point for the tension member is provided.
  • the anchor body consists of a substantially flat steel plate, which is cut at both ends in the manner of an arrowhead, and one on a flat side of the same by welded or riveted attachment shoe for the drive-in and guide rod, the latter also having an eyelet for fastening the tension member, is made according to DE-PS 27 11 979 the anchor body from a tubular section, the cavity for receiving the drive-in and Guide rod is suitable and has a molded taper in the front end to form an abutment shoulder for the drive rod.
  • the ground or ground anchor according to DE-PS 27 11 979 has compared to that according to US-PS 972 306 the advantage that it can be made in one piece without difficulty from a pipe section that does not have to be provided with any additional elements or attachments , because the attachment point for the tension member can consist of a cut-out tube part that is pressed out like a handle.
  • a disadvantage of both known ground or ground anchors is that, for the purpose of automatically swiveling in their anchoring position when force is exerted on the tension member, they must not only be cut obliquely to the longitudinal axis at their rear end and provided with a lip-shaped bend, but also also the Attachment point for the tension member must be provided so that it is on the opposite side of the downward bend of the rear end and between the center of gravity of the anchor body and its rear end.
  • ground or ground anchors Another disadvantage of the known ground or ground anchors is that they cannot be easily driven into stony ground.
  • the front tip of the steel plate is relatively easily bent sideways when it hits a flat, thicker stone, thereby preventing further penetration into a sufficient depth of the ground.
  • ground or ground anchor according to DE-PS 27 11 979 cannot pass through transverse stones because of its relatively large, annular end face and is thereby prevented from being driven in sufficiently deep.
  • the purpose of the invention is to remedy the shortcomings peculiar to the known ground or ground anchors.
  • the invention is therefore based on the object at the outset to improve the specified device for anchoring tension members, such as ropes, chains or the like, in the grown or also heaped up earth so that it can be pulled out and reused easily and not only in the event of a faulty driving in from the formed driving-in channel and enough tiege relieved even in stony soils, but at the same time brings about a significantly improved anchoring in the ground after proper driving.
  • tension members such as ropes, chains or the like
  • the anchor body is designed as a shaped piece with a tapered front end section and at the same time at its rear end with a profile for the non-rotatable positive engagement of the driver - And guide rod is provided that the attachment point of the tension member is provided between the center of gravity and the front end of the anchor body and that at the or in the area of the attachment point of the tension member is pivotally limited an arm whose rear end is assigned to the rear end of the anchor body is.
  • the splitting of such stones is facilitated because the anchor body can not only be rotated about its longitudinal axis during the driving-in process with the help of the driving-in and guide rod, but at the same time also by more or less strong inclination of the driving-in and guide rod from the area of the obstacle Stone can be distracted.
  • the spreading movement of the arm relative to the anchor body results in a barb or fan effect, which significantly improves the hold in the ground.
  • the arm can be swung out from a parallel position to the anchor body into an acute-angled inclined position relative to it.
  • the spreading of the arm relative to the anchor body is favored according to claim 3 in that the arm has blade-like deformations at its rear end which cut into the earth when a force is exerted on the tension member and force the lateral pivoting-out movement of the arm.
  • a structurally and functionally favorable design of the device according to the invention is achieved according to claim 4 in that both the anchor body and the arm have a T-shaped cross section and are articulated with each other via their T-web.
  • Another design of the device is characterized in that both the anchor body and the arm have a U-shaped cross-section and are articulated to one another via their U-legs. This configuration is suitable for use with particularly heavy-duty ground or ground anchors.
  • a particularly powerful design of the device according to the invention results if, according to claim 6, support stops are formed on the joint-side end of the arm to limit its pivoted-out inclination position.
  • anchor body and arm are detachably connected to one another and to the tension member via their common joint axis.
  • the spreading effect of the arm relative to the anchor body is finally further promoted by the fact that the tension member can be placed on the redistribution surfaces of the arm at least with its lower end section corresponding to its length.
  • the arm is forcibly pivoted out relative to the anchor body and thus advantageously supports the desirable spreading process.
  • tension members 31 for example ropes, chains or the like, in grown or also heaped-up soil with as little work as possible, but sufficiently secure for the respective application.
  • anchoring devices 32 which consist of an anchor element 33 with a small cross-sectional area relative to its length and of a drive-in and guide rod 34 which can be aligned longitudinally on this anchor element 33 and can be detachably coupled to it, as shown in FIG 1 of the drawing can be seen.
  • the anchor element 33 consists of an anchor body 33 a and an arm 33 b articulated to a limited extent at 35, the free or rear end of which is adjacent to the rear end of the anchor body 33 during the driving process into the soil 7, as is shown in FIGS , 3 and 4 is recognizable.
  • the tension member 31 engages, for example, a plastic-coated steel cable, a chain or the like.
  • the anchor element 33 can be driven into the grown soil 37 from above with the aid of the drive-in and guide rod 34 to form a drive-in channel 36.
  • more or less forceful hammer blows are applied to the upper end of the driving-in and guide rod 34 provided with a thickened head part 38.
  • the driving and guiding rod 34 and with it also the anchor element 33 during the driving process can be adjusted not only to the Rotate the longitudinal axis as desired, but it is also possible to influence the driving direction of the anchor element 33 into the soil 37.
  • the tension member 31 is also drawn into the drive channel 6 with the respective drive depth because it is connected to the anchor element 33.
  • the front end portion 40 of the anchor body 33 a is provided on all three profile sections of the T-cross section with bevels, so that it ends in a tip towards the free end.
  • the rear end 42 of the anchor body 33 a forms with its entire T-cross-section a flat support or stop surface for the front end of the driving and guide rod 34, as can be clearly seen in FIG. 3.
  • the arm 33 b of the anchor element 33 has at its end, which is adjacent to the joint 35 formed by a head pin, a stop surface 43 on its T-web, which limits its pivoting angle relative to the anchor body 33 a like that in a comparison of FIGS. 3 and 5 is immediately clear.
  • the rear end 44 of the arm 33 b is assigned to the rear end 42 of the anchor body 33 a, provided that the arm 33 b assumes a parallel position to the anchor body 33 a (FIGS. 1 and 3).
  • the free, lower end of the driving-in and guide rod 34 together encompasses the rear ends 42 and 44 of anchor body 33 a and arm 33 b, as is made clear by FIG. 3.
  • the drive-in and guide rod 34 with molded-in drive-in shoulders 45 rests on the rear end 42 of the anchor body 33 a and also encompasses this and the rear end 44 of the arm 33 b with a projecting edge 46 in a rotationally fixed manner. Rotation of the driving-in and guide rod 34 about its longitudinal axis thus also results in a corresponding rotation of the anchor element 33 about its longitudinal axis.
  • the articulation point 35 of the arm 33 b on the anchor body 33 a and thus also the point of attack of the tension member 31 on the anchor element 33 has a distance 48 from the tip 41 at the front end portion 40 of the anchor body 33 a, which corresponds to at most half the total length of the latter, preferably however, is smaller than this. It is hereby ensured that when a tensile force is applied, the tension member 30 inevitably results in a certain inclination of the anchor body 33 a in the drive-in channel 36, which leads to a lateral deflection of the anchor body 33 a from the drive-in channel and thus digging its ends 41 and 42 directed away from one another in the surrounding earth 37.
  • the arm 33 b Since during the deflection movement of the anchor body 33 a, the tension member 31 comes to rest on one of the two parallel profile legs of the arm 33 b and exerts a sideways force effect thereon, the arm 33 b is also pivoted about the articulation point 35 relative to the anchor body 33 a, while its blade-like deformations 37 dig in one direction into the surrounding soil 37, which leads away from the direction of burial of the end 42 of the anchor body 33 a. This results in a forced spreading apart of the arm 33 b relative to the anchor body 33 a until its support stop 43 abuts against the inside of a profile leg of the anchor body 33 a, as can be seen from FIG. 5. The spreading effect of the arm 33 b to the anchor body 33 a therefore has the result that the anchor element 33 enters into an optimal and high-strength connection with the soil 37.
  • the anchor body 33a and the arm 33b of the anchor element are detachably connected to one another and also to the tension member 31 via the joint bolt provided with a screw connection.
  • FIG. 6 shows a variant of the anchor element 33 according to FIGS. 3 to 5.
  • the anchor body 33 a and the arm 33 b do not have a T-shaped profile cross section, but rather each have a U-shaped profile cross section.
  • the U-profile cross-sections are provided with their open U-sides facing each other and the hinge pin 35 passes through both U-legs of both the anchor body 33 a and the arm 33 b.
  • the tension member 31 for example a wire rope, then acts on the hinge pin 35 by means of a rope thimble.
