Definitions

  • the invention relates to a ground anchor that can be driven into the ground for anchoring rod-shaped objects, such as anchoring pipes, posts or masts, in the area near the top edge of the terrain with an axially arranged receiving cavity for receiving the object to be anchored and with a section tapered in the driving-in direction, the foremost in the driving-in direction
  • the outer diameter of the tapered section essentially corresponds to the diameter of an anchoring rod that extends deeper into the ground and cooperates with the floor plug, but the larger outer diameter of the floor plug, which is in the driving-in direction, is several times larger than the diameter of the rod-shaped object to be anchored, and this is due to the outer lateral surface of the Volume enclosed by floor anchor corresponds to a multiple of the volume enclosed by the floor anchor of the object to be anchored.
  • a floor anchor with the features mentioned at the outset is described in CH-A-565 903 and serves in particular as an impact holder for road guide posts.
  • several chambers are provided which divide the hollow interior of the floor anchor by dividing walls and crumble the ground located inside the floor anchor when hammered in, so that after the hammering in, the soil can be easily removed from the hollow interior of the floor anchor.
  • the wall surrounding the partition walls and enclosing the interior of the floor anchor also extends like the dividing walls parallel to the direction of impact of the ground anchor to enable easy excavation of the enclosed soil. Radial displacement of the soil in the area of the ground anchor is neither achieved nor sought.
  • FIG. 1 Another such floor anchor is known from FR-A 2 290 552.
  • This consists essentially of a thin-walled, cylindrical metal sleeve for receiving the object to be anchored, on the outside of which at least two thin-plate, trapezoidal wings are welded to increase the anchoring stability against tensile and rotational forces.
  • the front section of the sleeve in the driving-in direction is tapered in a conical manner and opens into a steel mandrel starting from the floor dowel and reaching deeper into the ground and serving as anchoring rod. The steel mandrel is firmly connected to the floor anchor.
  • the floor anchor has unequal anchoring stabilities with respect to horizontally acting forces acting from different directions.
  • the floor plug essentially consists of an anchoring tube, on the rear end of which is arranged in the driving-in direction an anchoring pot which is open in the driving-in direction.
  • the diameter of the outer circumferential cup wall is larger than the diameter of the axially arranged anchoring tube.
  • the bottom of the pot is designed to be sufficiently stable so that both the anchoring tube and the pot can be driven into the ground by blows struck on the bottom.
  • the anchoring pipe By inserting the outer wall that cuts into the ground, the anchoring pipe can be loaded equally horizontally in all directions. However, since the wall is only in the top, relatively loose, no floor layer absorbing high floor pressure is cut, these floor layers break out at higher loads acting horizontally on the floor anchor, so that a secure and permanent anchoring cannot be achieved. If the floor anchor is subjected to torsional forces, an additional anti-rotation lock is necessary.
  • the invention is therefore based on the object of providing a floor dowel which can be driven into a multiplicity of different floor types using simple means and which ensures secure, permanent anchoring of a rod-shaped object held by the latter in the area near the top edge.
  • the floor plug has two sections tapered at different angles, the front section in the driving direction being tapered with a larger angle with respect to the longitudinal axis of the floor plug.
  • the floor dowel Since the floor dowel has two sections equipped with different tapering angles, the front section in the driving-in direction having the larger tapering angle, the anchoring surface of the object to be anchored and held by the floor dowel is considerably enlarged compared to forces acting from any direction.
  • the object anchored in this way is characterized by a high level of stability. Due to the conical taper, the floor anchor can also be driven into poorly sorted floors, since obstacles in the floor are pushed sideways away from the floor anchor. These then even have anchoring stabilizing effect.
  • the floor plug When driving into the ground, the floor plug displaces a multiple of the volume of the rod-shaped object enclosed by the floor plug and compresses it in the area adjacent to the floor plug, so that the floor plug is inserted on all sides in a floor that receives a high pressure.
  • the rear end face of the floor plug in the driving-in direction can be used as an anvil surface, so that the floor plug can be driven into the ground without damage without the aid of an additional setting tool.
  • holes can be made in the rear end face.
  • the cross-sectional area of the floor anchor increases from its front boundary in the driving direction essentially over its entire length intended for driving into the ground.
  • earth material is displaced on all sides in the entire conically tapered area, so that the ground anchor is therefore in direct contact with compacted soil material which absorbs a high ground pressure at all times.
  • the frictional connection formed in this way between the outer surface of the ground plug driven into the ground and the surrounding ground ensures permanent and non-rotatable ground connection of the ground plug as well as a favorable introduction of force into the surrounding ground. Due to its conical shape, the floor plug is slightly deeper after a possible enlargement of the set hole, for example after extreme floor drying Drive in again in a wedge-like manner and anchorable in the enlarged setting hole.
  • the receiving cavity is designed as a channel that axially traverses the floor plug and is open on both sides.
  • the front end of the object to be anchored in the driving direction extends deeper into the ground than the front boundary of the ground anchor.
  • the floor dowel surrounds the object to be anchored in its area near the top edge of the terrain, so that the rod-shaped object simultaneously represents the anchoring rod.
  • a rod-shaped object is directly attached to the floor plug, the section of the article which passes through the floor plug and extends deeper into the ground then constitutes the anchoring rod, or can be anchored indirectly in the ground, in which case, for example, an anchoring pipe is fixed directly by the floor plug.
  • grooves are introduced circumferentially into the floor dowel following the longitudinal extent thereof.
  • the grooves are notch-shaped, the deepest of the grooves having an increasingly greater radial distance from the longitudinal axis of the floor anchor, starting from its front end in the driving-in direction.
  • Providing the grooves increases the surface area of the ground anchor in contact with the ground.
  • certain groove flanks formed by the grooves represent essentially orthogonal surfaces with respect to acting horizontal forces, which additionally increase the anchoring stability.
  • guide slots are introduced circumferentially into the floor dowel following the longitudinal axis thereof, into which plate-like anchoring ribs can be inserted.
  • plate-like anchoring ribs can be inserted.
  • a fastening sleeve is provided in the area of its front section, which has circumferential hanging slots corresponding to the arrangement of the guide slots.
  • the suspension slots are in engagement with a gripper hook located on each anchoring rib and pointing against the driving direction.
  • the anchoring ribs can be suspended in a recessed fastening ring using conically tapered clamping nipples.
  • the floor anchor is expediently producible from an easily machinable material, for example from wood, or also from recycling materials, for example from plastic granulate or from shredded motor vehicle tires.
  • the floor dowel can also be manufactured as a hollow body, which in a steel version is preferably composed of three components, namely a rear anvil part, a front hollow tip and a sleeve connecting the anvil part and the hollow tip.

  • the longitudinal extension of the floor anchor 1 is a multiple of its largest outside diameter.
  • a short cylindrical section 5 is arranged behind the tapered section 4.
  • the rear end face 6 of the floor plug 1 is flat and thus designed as an anvil surface for driving in the floor plug 1.
  • the rear area of the cylindrical section 5 is reduced in diameter compared to the rest of the cylindrical area, so that a shoulder 7 is formed.
  • a protective cap (not shown) can be attached to the reduced-diameter cylindrical area, so that damage is avoided when driving in the floor anchor 1 by hammer blows.
  • a channel 8 serving as a receiving cavity extends axially through the floor dowel 1, the cross section of which is circular and the diameter of which essentially corresponds to the diameter of a rod-shaped object to be anchored.
  • a reinforcing metal ring designed as a cutting edge is provided on the front edge 9 in the driving-in direction, so that when the floor anchor 1 made of wood is driven into already highly compacted or gravelly soils, damage to the front edge 9 is prevented.
  • a plurality of notch-shaped grooves 10 are made in the floor dowel 1.
  • the radial distance of the deepest groove 11 of the grooves 10 with respect to the longitudinal axis of the floor anchor 1 increases increasingly starting from the front boundary of the grooves 10 with respect to the longitudinal axis in the driving-in direction.
  • the grooves 10 are closed at their rear end 13 in the driving direction. Since in this embodiment the material located between the flanks of the groove is also subjected to pressure when driving in the floor anchor and is also compressed, the floor anchor is particularly well secured against attacking rotational forces after driving in.
  • the deepest groove runs parallel to the longitudinal axis of the floor anchor, so that they deepen in accordance with the taper angle of the floor anchor. Since the driving-in resistance is reduced in this way, such a groove configuration is expedient when the floor anchor is used in already highly compacted soils.
  • bores 14 are made for fastening objects.
  • Fig. 2 shows a reduced cross-section of the floor anchor 1 along the line II-II of Fig. 1.
  • the substantially round cross-section of the floor anchor 1 can be seen as well as the notch-shaped design of the grooves 10 and the considerably larger compared to the diameter of the channel 8 Outer diameter of the floor anchor 1.

  • passages 22 are introduced into the protective cap 17 at corresponding points.
  • Fig. 4 shows a perspective exploded view of a first application example for the floor dowel 1.
  • the floor dowel 1 serves as anchoring near the top of the edge of an anchoring pipe 26 which extends deeper into the ground with its tip 25, so that an anchoring device for the indirect anchoring of rod-shaped, the anchoring tube 26 to be used Objects is created.

  • the collar 29 prevents the anchor pipe 26 from slipping through the channel 8 of the floor anchor 1.
  • the inner ring 21 of the protective cap 17 can be fitted, so that both the anchoring tube 26 and the ground dowel 1 can be driven into the ground by hammer blows applied to the protective cap 17.

If permanent protection of the rear region of the floor anchor in the driving-in direction is additionally desired, the protective cap 17 is then placed over the striking surface 6 on the rear end of the floor anchor 1 and fastened to it. By Hammer blows on the striking surface 6 or on the protective cap 17, the anchoring tube 26 and the ground dowel 1 are driven into the ground until the striking surface 6 or the upper edge of the protective cap 17 essentially end with the top edge of the terrain.

Since the anchoring tube 26 is also firmly anchored in the ground by its tip 25, it is clear that this two-point anchoring means that the anchoring tube 26 requires a much lower foundation depth to achieve a certain stability than an anchoring tube that has been driven into the ground without using the ground plug 1 is and can therefore only be understood as a one-point anchorage.
  • the actual object to be anchored in the ground for example a post 31, is to be inserted into the driven anchoring device consisting of anchoring tube 26 and floor dowel 1 for indirect anchoring and, if necessary, fastened to the floor dowel 1.
