Definitions

  • the invention relates to a device for anchoring tensile members, such as ropes, chains or the like, in grown or also heaped-up soil, consisting of an anchor body designed as a molded part with a cross-sectional area that is small in relation to its length and of a longitudinally alignable and detachable on the anchor body 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.
  • ground or ground anchors are already known as so-called ground or ground anchors, as can be seen, for example, from US-PS 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 a slip-on shoe fastened on a flat side thereof by a welded or riveted connection for the drive rod, the latter also having an eyelet for fastening the tension member
  • the anchor body is made according to DE-PS 27 11 979 from a tube section, the cavity of which is suitable for receiving the drive rod and a molded taper in the front end to form a Has contact 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 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 deflection, but at the same time also Attachment point for the tension member must be provided so that it must be on the opposite side of the outward bend of the rear end and between the center of gravity of the anchor body and its rear end.
  • ground or ground anchor according to DE-PS 27 11 979 cannot pass 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 overcome the shortcomings peculiar to the known ground or ground anchors.
  • the object of the invention is therefore a device for anchoring tension specified in more detail at the outset structure such as ropes, chains or the like, in the grown or heaped up soil so that they can be easily pulled out of the formed driving channel and reused even in the event of a faulty driving in, but also considerably facilitates deep enough driving into stony ground layers .
  • the anchor body is designed as a shaped piece with a tapered front end section and at the same time provided at its rear end with a profile for the non-rotatable positive engagement of the drive-in and guide rod is and that the attachment point of the tension member is provided between the center of gravity and the front end of the anchor body and consists of a shekel, a ring loop or a chain link which articulates in transverse bores.
  • the aforementioned innovation measures not only facilitate the correct driving in of the anchor bodies to the desired depth even on stony soils, but also ensure that an anchor body that is inadvertently incorrectly set is pulled out of the input channel again by means of the drive-in and guide rod used and subsequently can then be reused.
  • the front end of the anchor body which is tapered like a blade, not only facilitates penetration into normal soils, but also contributes to the splitting of stones that are located in the area of the driving channel in the soil.
  • 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 aid 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 rods the area of the stone acting as an obstacle can be deflected.
  • a design of the anchor body has proven itself according to the invention, in which, according to claim 2, the front end section thereof has an approximately semicircular channel cross section. Apart from the fact that this gives the front end section of the anchor body, which is tapered in the manner of a blade, high dimensional stability, the anchor body can also act like a drill by rotating about its longitudinal axis and either penetrate stones protruding into the driving channel or are deflected by them and guided past them.
  • the channel cross-section runs out in the direction of the fastening point on the circumference of the anchor body.
  • both the driving in and the pulling out of an inadvertently incorrectly placed ground or ground anchor is favored if, according to the invention, the profiling for the rotationally fixed positive engagement of the driving and guide rod at the rear end of the anchor body has a cross-sectional dimension that has the largest cross-sectional dimensions falls below it.
  • the profiling for the rotationally fixed form engagement of the drive-in and guide rod can stand from an axially parallel recess in the rear end of the anchor body, which is assigned a correspondingly profiled engagement pin at the front end of the drive-in and guide rod.
  • the profiling for the non-rotatable positive engagement of the driving and guide rod consists of an axially parallel pin at the rear end of the anchor body, which is assigned a correspondingly profiled recess at the front end of the driving and guide rod.
  • a particularly advantageous mode of operation of the ground or ground anchor is achieved according to the invention if, according to the teaching of claim 6, the attachment point of the tension member on the anchor piece is in an area that is approximately one third of the total length of the front End and consequently about two thirds of the total length of its rear end is provided.
  • the shekel, the ring loop or the chain link with its free end can be assigned to the side of the anchor piece corresponding to the rear or the front of the channel profile, the shekel preferably being detachable, e.g. screwed axle bolt is connected to the anchor piece, which is formed by a molding from solid and tubular material.
  • An earth or ground anchor according to the invention fulfills optimal conditions if, according to the proposal of claim 8, the channel cross-section at the front end section of the anchor body has a greatest wall thickness, approximately in a ratio of 0.25: 1 to the largest channel width and approximately to the largest channel height is in a ratio of 0.38: 1.
  • the drive-in and guide rod is provided below its top end, which is provided with a head-like thickening, with two holding, guiding and rotary drive handles directed radially and on opposite sides.
  • the anchor body can also be formed from a cross-sectionally T-shaped or + -shaped profile section, in which two parallel flanges are deformed in the region of the front end section to form the channel profile, while there the one or the transverse teten flanges are cut away to the attachment point for the traction device.
  • tension members for example ropes, chains or the like
  • tension members for example ropes, chains or the like
  • anchoring devices 2 which consist of an anchor body 3 designed as a molded part with a small cross-sectional area relative to its length and of an insertion and guide rod 4 that can be aligned in the longitudinal direction on this anchor body 3 and detachably coupled to it, as is the case here overall from Fig. 7 of the drawing is apparent.
  • the tension member 1 is also drawn into the driving channel 6 in accordance with the respective driving depth because it is connected to the anchor body 3.
  • the anchor body 3 consists of a shaped piece which is either made from a solid rod material or from a tube section as a molded part.
  • the front end section 10 of the anchor body is shaped into an approximately semicircular channel cross section, which tapers to a cutting edge 11 towards the lower end, while at the rear end 12 it has, for example, a long round or deviating from the circular pipe cross section according to FIG. 5 has oval profiling, as can be clearly seen from FIG. 6.
  • the anchor body 3 is provided with a circumferential deformation 13 lying essentially on the plane of symmetry with respect to the channel cross section, the smallest cross-sectional dimension of which lies on the longitudinal axis of transverse bores 14 which receive a bolt 15, which, for example, has a leg 16 carries on which the tension member 1 is attached.
  • the long round or oval profile at the rear end 12 of the anchor body 3 serves for the releasable but non-rotatable positive engagement of a pin 17 fastened to the front end of the driving-in and guide rod 4, such that rotation of the driving-in and guide rod about its longitudinal axis also results in a corresponding rotation of the anchor body 3 within the driving channel 6.
  • the engagement of the pin 17 in the end 12 of the armature body 3 is also sufficiently stable to ensure that an inclination shift of the driving and guide rod 4 in the driving channel 6 forces a corresponding inclination shift of the armature body 3 while the driving-in process is being carried out.
  • the anchor body 3 can be driven into the soil 7 according to the respective needs and if necessary, can also be guided past stones located in the area of the driving channel 6, provided that these are not destroyed by the cutting edge 11 at the front end section 10.
  • An important training criterion of the anchor body 3 also lies in the fact that the fastening point 5 for the tension member 1, i.e. the transverse bores 14 for receiving the bolt 15 or a ring loop or a chain link, have a distance 18 from the cutting edge 11 of the front end section 10, the corresponds to approximately one third of the total length of the anchor body 3 and thus has a distance 19 from the rear end 12 thereof, which makes up approximately two thirds of the total length.
  • This configuration ensures that the fastening point 5 for the tension member 1 on the anchor body 3 lies between its center of gravity and the cutting edge 11 formed at the front end.
  • the profiling for the non-rotatable positive engagement of the pin 17 of the driving and guide rod 4 at the rear end 12 of the anchor body 3 has a cross-sectional dimension which is less than the larger cross-sectional dimensions thereof, so that the part of the bolt 17 adjoining it Driving-in and guide rod 4 can receive cross-sectional dimensions that nowhere exceed the largest cross-section of the anchor body 3.
  • the drive-in shoulders 20 of the drive-in and guide rod 4. therefore complete everywhere flush with the rear end 12 of the armature body 3, so that a perfect interaction of the driving and guide rod 4 with the armature body 3 is ensured at all times.
  • the upper end 12 of the anchor body 3 cannot claw in the soil 7 surrounding the driving-in channel 6, as long as the driving-in and guide rod 4 is still in engagement with it and takes over the leadership within the driving-in channel 6. it is therefore easily possible to inadvertently incorrectly drive anchor body 3 driven into the ground 7 together with the one drive and guide rod 4 again to be lifted out of the drive channel 6, simply by pulling on the tension member 1.
  • the armature body 3 removed from the driving channel 6 can thus be reused without great difficulty.
  • the anchor body 3 As soon as, after the anchor body 3 has been properly driven in, the drive-in and guide rod 4 is pulled out of its upper end 12, when the tensile force acts on the tension member 1, the anchor body is inclined under the action of its center of gravity located above the fastening point 5 in the drive-in channel 6 and penetrates with its upper one End 12 with simultaneous pivoting about the fastening point 15 transversely into the surrounding soil 7, while the front end section 10 also penetrates sideways into the surrounding soil with pivoting to the opposite side and a certain upward displacement. In the position shown in FIG. 8, the anchor body 3 has reached its end position and holds the tension member 1 securely in the ground.
  • an embodiment of an anchor body 3 which is modified compared to FIGS. 1 to 8 is shown.
  • This anchor body 3 is made from a profile section which is approximately T-shaped in cross section, for example a rolled profile, in which two parallel flanges 21 ′, 21 ′′ are bent in the region of the front end section 10 to form the channel profile, while there the flange directed transversely thereto is cut away to the attachment point 5 for the tension member 1 with a beveled end edge so that the channel profile with its cutting edge 11 can penetrate more easily into the grown soil.
  • the driving and guiding rod for the anchor body 3 according to FIGS. 9 to 11 can be slotted at its lower end according to the position of the flanges 21 ', 21 ", 21"' in order to bring about a non-rotatable positive engagement with the anchor body 3.
  • the anchor body 3 according to FIGS. 12 to 15 is a direct modification of the embodiment shown in FIGS. 1 to 6.
  • the circumferential deformation 13 is also formed in the area of the fastening point 5 for the tension member 1. It also consists of two surfaces 13 'constricting the round material cross section, which lie parallel to one another and to the surfaces 12 "of the profiling 12'.
  • the guide rod 4 must have a cavity instead of the pin 17, which can positively encompass the profile 12 'at the rear end 12 of the anchor body 3.
  • the anchor body 3 according to FIG. 16 is formed from a solid round wire section.
  • the front end having the cutting edge 11 and the rear end 12 carrying the profiling 12 ' have the same design as in FIGS. 12 to 15.
  • the fastening point 5 for the tension member 1 is, however, simply created here by forming a wire winding loop 5' .
  • the tension member 1 can optionally be passed directly through the latter.
