Definitions

  • the present invention relates to a device for ground anchoring of stay wires, for example as used for the anchoring of steel wires utilized in connection with power pylons.
  • Such ground anchoring is today normally achieved using a support member, having an eye-shaped member at one end portion, facilitating attachment of the stay wire, and having an externally threaded part at the opposed end portion for engagement with a nut.
  • a support member may, for example, be used together with railway sleepers, in which a through hole has been taken up. The support member is inserted through said hole with the threaded portion as a first part, whereafter a washer-shaped member, and the nut, are attached at the opposed side of the sleeper. The sleeper with attached support member can thereafter be lowered into a hole taken up for this purpose, which thereafter is filled up again.
  • the above described known type of ground anchor has a number of disadvantages.
  • Use of support members comprising a threaded end portion means that today existing standards relating to the thickness of galvanization below ground surface (215 ⁇ m) require galvanization of the threaded portion in two steps. This involves more work and thus higher costs, but also that existing standard can not always be fulfilled.
  • a further disadvantage is that the screw thread constitutes the weak part of the support member, and that the support member must be dimensioned based on the tensile properties of the screw thread.
  • Handling support members with screw thread during winter conditions also involve problems, since same often lie outside before use and the screw thread can be filled with ice.
  • the nut attached to the support member may thus be difficult to remove, and the ice can not be removed, e.g. by blows directed towards the ice from a hammer, since the screw thread may be damaged.
  • Sometimes may also the nut, for example during transport. work itself loose and disappear with associated washer.
  • the object of the present invention is to disclose a device for ground anchoring which removes the disadvantages discussed above. Similar to the above discussed prior arrangement, it is intended to be dug down under the ground level, and the anchoring member may comprise of a sheet metal piece, a lump of concrete or a sleeper (railway sleeper).
  • the support member used lacks a threaded end portion, intended to co-act with a nut, which makes it possible to obtain desired thickness of the galvanization in one operation only. Since the tensile properties of the anchoring is no longer related to the tensile properties of previously used screw thread, the support member can also be manufactured having smaller dimensions than previously possible.
  • the device for ground anchoring of stay wires according to the present invention for example used for anchoring steel wires utilized in connection with power pylons, which are attachable to a substantially eye-shaped member arranged adjacent to an end portion of a support member, is mainly characterized in that the support member also adjacent to the end portion intended to be located below a ground surface is arranged having an eyeshaped member, co-acting with and attachable to a substantially washer shaped lock means having an area exceeding the cross-sectional area of a through hole or groove taken up in an anchoring element through which the support member is intended to extend and be attached.
  • the lock means is advantageously arranged with a groove shaped part open in one direction, having a width facilitating insertion of the support member but which is smaller than the external dimensions of the eyeshaped member.
  • a preferably substantially L-shaped member be arranged having a free part extending over at least a portion of the groove shaped part in a substantially parallel relationship to the lock means and in direction towards the open end portion of the groove shaped part, said free end portion being arranged having a width and a distance from the lock means facilitating that same is inserted into the through hole of the eyeshaped member, and that a portion extending out from said hole is bent over towards or away from the lock means, thereby locking together the eyeshaped member and the lock means to an internally joined condition.
  • FIG. 1 shows a cross-sectional view of an anchoring member 1 indicated with broken lines, e.g. a railway sleeper, through which a support member 2 extends.
  • the support member 2 is moved through the anchoring member 1 until a threaded end portion 3 protrudes from the side opposed to the side from which insertion is performed, whereafter at least one washer 4 and a nut are applied.
  • a larger washer-shaped member 6 has also been included between the washer 4 and the anchoring member 1, intended to result in a larger pressure contact surface, but same can be excluded in many cases.
  • a stay wire can be attached in a conventional fashion to an eyeshaped member 7, arranged at the free end portion of the support member 2 (opposed to the threaded end portion 3).
  • Said support member 2 advantageously is modified according to the present invention.
  • Said support member 2 has, as previously known, a first end portion with an eyeshaped member 7 for the attachment of a stay wire, but in difference to known techniques, an eyeshaped member 8 is also arranged at the second end portion. It is obvious, that such an arrangement in a simple way can be surface treated, e.g. by means of galvanization, and with desired thickness of coating. There are also other advantages, which will become apparent from the following description.
  • the support member 2 described with reference to Fig. 2 can be used in conjunction with, for example, a plate shaped anchoring member 9 and an associated lock washer 10, which in a speedy and simple fashion facilitate connection with the eyeshaped member 8 of the support member 2.
  • a plate shaped anchoring member 9 and an associated lock washer 10 which in a speedy and simple fashion facilitate connection with the eyeshaped member 8 of the support member 2.
  • Said lock washer in its entirety denominated 10, is shown in Figs. 3A - 3C, and includes four tongues 11, 11', 11", 11"' extending as pairs in a first direction away from two in relation to each other opposed edge portions at an originally substantially square sheet metal member. Furthermore, a substantially L-shaped and central member 12 is also formed from said sheet metal member, thereby creating a through groove, extending slightly passed the centre of the member. As disclosed in the figures, both the tongues 11, 11', 11", 11"' and the L-shaped member 12 are thus created by a punching operation from the sheet metal member, i.e. by use of suitably designed press tools, the lock washer 10 can be completely manufactured by one or two press operations.
  • FIG. 4 A basic example of a plate shaped anchoring member 9 is shown in Figs. 4 and 5, the outer configuration of which may obviously be arranged as desired.
  • the plate shaped anchoring member 9 is arranged having four holes 13, 13', 13", 13"' having an internal relationship adapted to the tongues 11, 11', 11", 11"'.
  • a centrally located through groove 14 is also arranged, having an extension exceeding the width of the eyeshaped member 8.
  • the groove 14 is arranged longitudinally displaced towards one side in relation to the centre of the as pairs arranged holes 13, 13', 13", 13"'.
  • the shorter extension of the groove 14 from said centre is arranged to correspond, or slightly exceed, the outer diameter of the support member 2, whereby same can be located substantially central in the groove 14 when the eyeshaped member 8 has been moved through the groove 14.
  • the eyeshaped member 8 is moved through the groove 14 in the plate shaped anchoring member 9, as illustrated in Fig. 6, in which the direction of travel is indicated by an arrow.
  • the support member 2 is thereafter moved in the groove 14 to a substantially central position in relation to the surrounding holes 13, 13', 13", 13"', and the support member 2 is simultaneously rotated approximately 90° in relation to the position taken up during the movement of the eyeshaped member 8 through the groove.
  • the eyeshaped member 8 should now be located at such a distance from the anchoring member 9 that the lock washer 10 can be moved to the position shown in Fig. 7 (with the direction of movement indicated by an arrow). In this position, the portion of the support member 2 adjacent to the eyeshaped member 8 is located in the groove 14, and the free end portion of the L-shaped member 12 is arranged extending through the hole of the eyeshaped member 8.
  • the tongues 11, 11', 11", 11"' will take up a position extending through the holes 13, 13', 13", 13"', whereafter the tongues 11, 11', 11'', 11''' and the free end portion of the L-shaped member 12 by means of strokes from a hammer, a small sledge hammer or similar are bent to positions locking the anchoring member 9 and the lock washer 10 together, and also locking the eyeshaped member 8 to the lock washer (Fig. 8).
  • the unit thus joined can thereafter be lowered into a hole taken up for this purposes and extending below the ground surface, which thereafter is refilled with the free end portion of the support member 2 with associated eyeshaped member 7 located extending upwards from the ground surface, utilized for conventional attachment of a stay wire.
  • the above described embodiment utilizes a plate shaped anchoring member 9, which obviously can be adapted with regard to configuration and size to existing load demands.
  • such a hole in utilized anchoring member may also be arranged as a through groove, whereby a member co-acting with the lock washer can be excluded.
  • a member co-acting with the lock washer can be excluded.
  • a support member 2 having an eyeshaped member 7, 8 adjacent to each end portion, and the interaction of same with a lock washer 10 having a groove shaped part with a width which preferably slightly exceeds the cross-sectional diameter of the support member 2.
  • the lock washer 10 arranged having a preferably L-shaped member 12, having the free and in relation to the plane of the lock washer 10 substantially parallel part arranged to extend through an eyeshaped member 8 when same is arranged extending across the groove shaped part.
  • the free end of the part extending through the eyeshaped member 8 can hereby when made subject to, for example, strokes, be bent over and thereby prevent separation of lock washer 10 and support member 2.
  • the lock washer 10 may also include means 11, 11', 11", 11"' extending towards a utilized anchoring member, said means 11, 11', 11", 11"' arranged to grip into, or facilitate interlocking with, the anchoring member.
  • the anchoring member may alternatively include a through groove or a substantially cylindrical hole through which the eyeshaped member 8, intended to be joined to the lock washer, can pass through.
  • the groove shaped part of the lock washer 10 is advantageously arranged in a crosswisely extending relationship when in mounted position.
  • the possibility to arrange the eyeshaped member 8 having a width exceeding the width of the groove can be mentioned, and such a modification facilitates a different extension for the free end portion of the L-shaped member 12 in relation to the groove.
  • Such a width for the eyeshaped member 8 may also facilitate that said L-shaped member 12 is excluded, e.g. by arranging means fixing the lock washer 10 and the support member 2 in a joined condition in relation to the anchoring member, for example by means of previously described co-acting means 11, 11', 11", 11"' and 13, 13', 13", 13"' respectively.
