Definitions

  • a ground anchoring system in which a generally flat anchor plate includes transverse slots for receiving and retaining one end of a flexible anchoring web or strap, the plate being driven edge-first into the ground by a driving tool with the other end of the web or strap connected to the object being anchored.
  • the plate When the driving tool is removed and a lifting force is subsequently applied to the flexible web or strap, the plate tends to skew across the hole and thereby resist extraction from the ground.
  • An object of the present invention is to provide an anchor plate which overcomes the above problem but without substantially increasing the resistance of the plate when being driven downwardly into the ground.
  • a ground anchoring system comprising an anchor plate which, in use, is driven edge-first into the ground by a driving tool, the plate having a projecting tail flap and transverse slot means for receiving and retaining one end of a flexible anchoring strap or web, characterised by an elongate socket for receiving the driving tool, the socket being disposed toward the leading edge of the plate beneath the transverse slot means such that the plate is aligned with the tool while being driven into the ground, the tail flap being retained by a cooperating portion of the tool in a first cocked position offering minimum drag resistance when the tool is located in the socket but being biased for movement into a second position inclined at a greater angle to the plate when the tool is withdrawn from the socket.
  • the tail flap In its cocked position (i.e. the position from which it can be released) the tail flap is generally aligned with the plate, the angle being generally in the range of 0 to 15° and preferably less than 10°. It therefore offers minimal resistance to the downward movement of the plate into the ground.
  • the angle In its released position, on the other hand, the angle increases and generally lies in the range of 20° to 60° with a preferred range of 30° to 45°.
  • the increased angle brings the trailing edge of the tail flap into contact with the side of the channel cut by the plate when driving it into the ground.
  • the flap therefore provides a fulcrum about which the plate pivots into a skew position across the channel when the anchor line is tensioned.
  • the tail flap is preferably resiliently biased but may alternatively fall freely into the released position under the force of gravity when the driving tool is removed from its socket. It may comprise a deformable strip projecting from the trailing edge of the plate, or it may be hinged to the trailing edge.
  • a generally flat, wedge-shaped anchor plate 10 includes a pair of slots 11, 12 for receiving a flexible anchoring strap or web 13.
  • a looped end 13a of the strap 13 is inserted through the lower slot 12 from the rear side (as viewed in Fig. 1), and is then fed back through the upper slot 11.
  • a split elongate retaining ring 14 receives the looped end and prevents the strap being withdrawn from the slots.
  • An elongate socket 15 is welded to the front side of the plate 10 for receiving an extended driving rod 22 (Fig. 3) of an hydraulic hammer tool (not shown) such that the leading edge 30 of the plate can be driven downwardly into the ground.
  • the rod 22 fits into the socket with a loose push fit and maintains the plate 10 aligned with the rod in a substantially vertical orientation when driving the plate into the ground.
  • a flap 17 projects rearwardly from the trailing edge 18 of the plate 10.
  • a longitudinally split hollow tube 19 is welded to the trailing edge 18 and pivotally mounts a spindle 20 secured to a central portion 21 of the flap.
  • the flap 17 is thereby hinged to the trailing edge 18 and is movable through an angle determined by the width of the slit in the tube 19. It is resiliently biased by springs 23 into the position shown in full outline in Fig. 2, the angle 6 2 being approximately 40°. The other extreme position is shown by the chain-dot outline in Fig. 2, the angle 6, being approximately 5°.
  • Figs. 3 and 4 The operation of the system is illustrated in Figs. 3 and 4.
  • the object being anchored (not shown) is attached to the top end of the strap 13.
  • the driving rod 22 of the hammer tool is then inserted into the socket 15.
  • the hinged flap 17 To insert the rod into the socket, the hinged flap 17 must first be moved back against its resilient bias into the cocked position shown in full outline in Fig. 3.
  • the rod 22 once inserted in socket 15 then holds the flap 17 in its cocked position against the bias of spring 23, the rod being accommodated by the recess 31 (Fig. 1) in the rear edge of the flap.
  • the hammer is then actuated to drive the plate 10, strap 13 and rod 22 into the ground, the location of rod 22 in socket 15 maintaining the plate aligned in the rod with a generally vertical orientation as shown in Fig. 3.
  • the rod 22 is withdrawn from socket 15 and the flap 17 automatically springs into the position shown in chain-dot outline in Fig. 3.
  • the serrated rear edge 24 of the flap digs into the side of the hole 25 and thereby resists reverse upward movement of the plate.
  • it immediately provides a fulcrum about which the plate 10 is forced to pivot to a skew position as shown in Fig. 4 when the strap 13 is subsequently tensioned by lifting forces applied to the object being anchored. This action ensures that the plate is immediately locked in its skew position and cannot be pulled back up the hole.
  • the centre of gravity of the plate 10 is positioned above the lower slot 12 so that the plate will tend to rotate in the direction shown by the arrows in Fig. 4 when the rod 22 is withdrawn from socket 15. This further assists in urging the serrated edge 24 of flap 17 into engagement with the side of the hole 25.
  • a short bar 26 welded to the ring 14 spaces the strap 13 from the rear face of the plate 10 so that an additional turning moment is applied in the direction of the arrows shown in Fig. 4 when the strap 13 is tensioned.
  • the forces on the plate are such that it continues to rotate into a generally horizontal locked position as the rear edge 24 of the flap 17 digs further into the side of the hole.
