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 2,711,979.
  • 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 a slip-on shoe for the drive-in and guide rod, which is fastened by welding or riveting on a flat side thereof, the latter also having an eyelet for fastening the tension member has, according to DE-PS 2 711 979, the anchor body is made from a tubular section, the cavity of which is suitable for receiving the drive-in and guide rod and has a molded-in taper in the front end to form an abutment shoulder for the drive rod.
  • the ground or ground anchor according to DE-PS 2 711 979 has the advantage over that according to US-PS 972 306 that it can be made in one piece without difficulty from a pipe section which 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 previously known ground or ground anchors is that, for the purpose of automatically pivoting into 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.
  • 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 of improving an initially specified device for anchoring tension members, such as ropes, chains or the like, in the grown or also heaped-up soil so that it is not only easily formed in the event of incorrect driving Pull out the driving channel and reuse it, making it easier to drive into stony soils from a sufficient depth, but at the same time, after proper driving, it brings about a significantly improved anchoring in the ground.
  • 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 drive-in and guide rod is provided that the attachment point of the tension member between the center of gravity and the front end of the anchor body is provided and that at the or in the area of the attachment point of the tension member is pivotally limited articulated an arm, the rear end of which is assigned to the rear end of the anchor body, and which, together with the anchor body, forms an expandable anchor element.
  • 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 ground when a force is exerted on the tension member and force the arm to pivot out to the side.
  • 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 armature 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.
  • 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 heaped-up soil with as little work as possible, but sufficiently secure for the respective application.
  • anchoring devices 32 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 that can be aligned longitudinally on this anchor element 33 and detachably coupled to it, as is shown in FIG 1 of the drawing can be seen.
  • the anchor element 33 consists of an anchor body 33a and an arm 33b 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 shown in FIGS. 1, 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.
  • the ei nem thickened head part 38 provided, upper end of the driving and guide rod 34 more or less powerful hammer blows.
  • the driving and guiding rod 34 and with it also the anchor element 33 during the driving process can be made not only by 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 36 with the respective drive depth because it is connected to the anchor element 33.
  • the front end section 40 of the anchor body 33a is provided with bevels on all three profile sections of the T cross section, so that it tapers into a tip toward the free end.
  • the rear end 42 of the anchor body 33a forms with its entire T cross-section a flat support or stop surface for the front end of the driving-in and guide rod 34, as can be clearly seen in FIG. 3.
  • the arm 33b 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 33a as in a comparison of FIGS. 3 and 5 is readily apparent.
  • the rear end 44 of the arm 33b is assigned to the rear end 42 of the armature body 33a, provided that the arm 33b assumes a parallel position to the armature body 33a (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 the armature body 33a and arm 33b, as shown in FIG. 3.
  • the drive-in and guide rod 34 rests with molded-in drive-in shoulders 45 on the rear end 42 of the armature body 33a and encompasses this as well as the rear end 44 of the arm 33b 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 two T-legs lying in the same plane are provided with deformations 47 which are bent out like a shovel, as can be clearly seen in FIGS. 3 to 5.
  • the articulation point 35 of the arm 33b on the anchor body 33a and thus also the point of engagement of the tension member 31 on the anchor element 33 has a distance 48 from the tip 41 at the front end section 40 of the anchor body 33a, which corresponds to at most half the total length of the latter, but preferably less than this is measured. It is hereby ensured that when a tensile force acts, the tension member 30 inevitably results in a certain inclination of the anchor body 33a in the drive-in channel 36, which leads to a lateral deflection of the anchor body 33a out of the drive-in channel and thus a digging in of its ends 41 and 42 directed away from one another in the surrounding area Soil 37 enforces.
  • the arm 33b Since, during the deflection movement of the anchor body 33a, the tension member 31 comes to rest on one of the two parallel profile legs of the arm 33b and exerts a sideways force effect thereon, the arm 33b is also pivoted about the articulation point 35 relative to the anchor body 33a while its blade-like Digging deformations 37 into the surrounding soil 37 in a direction away from the digging direction of the end 42 of the anchor body 33a.
  • the spreading effect of the arm 33b to the anchor body 33a therefore has the consequence 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 33a and the arm 33b 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 33a and the arm 33b.
  • the tension member 31 for example a wire rope, then acts on the hinge pin 35 by means of a rope thimble.
