- the invention relates to an earth anchor, which for anchoring a tension element can be screwed into the ground, with a Anchor part, on which a bottom end of the tension element is attachable and which has an anchor tip and at least has a screw wing.
- the invention further relates to a method for producing an earth anchor with a tension element and a method for anchoring a tension element in the Soil by means of an earth anchor, in which the tension element on one Anchor part of the anchor attached and by means of this in the ground is screwed in.
- U.S. 4,316,350 A generic state of the art goes out, for example U.S. 4,316,350.
- this known ground anchor is a one-piece anchor part provided with a threaded bore, in which can be screwed in a rod-shaped tension element.
- the Anchor part includes a tip with an adjoining one Helix.
- About a sleeve-shaped installation part the tension element together with the anchor part in the ground up to screwed in to a desired depth. Then that will bag-shaped installation part detached from the anchor parts and out of the Floor pulled out.
- the invention is based on the object of specifying an earth anchor and a method with which an inexpensive anchoring of tension elements is possible. Furthermore, it is an object of the invention to provide a manufacturing method for such an earth anchor.
- the respective task is carried out by an earth anchor with the characteristics of claim 1, a method of manufacturing an earth anchor according to claim 14 or a method for anchoring a Pulling element according to claim 15 solved.
- Anchor part is modular and an anchor tip module and has at least one separate screw module. Preferably several screw-wing modules are provided.
- a basic idea of the invention is the separation of the anchor part into individual function modules.
- For the firmness of a Screw anchoring is primarily the shape and length of the Screw sash decisive.
- a base wing segment provided which according to the requirement to the anchorage in almost any number an armature tip module can be arranged in series. It can easily use different types of ground anchors with a wide variety of anchoring properties as required can be assembled in a modular principle.
- the individual modules can be in large numbers and thus can be produced inexpensively.
- Screw anchor is achieved according to the invention in that between individual wing modules or groups of Screw-wing modules arranged sleeve-shaped spacing modules are.
- the additional use of distance modules is based based on the knowledge according to the invention that the largest possible Increase in anchorage strength when using several Wing modules are achieved when larger ones Floor sections between the individual screw-wing modules or from groups of screw-wing modules of two, three or more Wing modules remain.
- a particularly large increase in strength with the smallest possible axial length the anchor part is achieved according to the knowledge of the invention that the length of the distance module is about three times Outer diameter of the screw wing turn corresponds.
- This embodiment according to the invention is thereby preferred further developed that to form the module connection Side of a module has a first connection side, while the opposite side of the adjacent module is one has second connection side, which is positive and / or non-positive can be connected to the first connection side.
- the Wing modules can be used in any way with the distance module be combined and lined up.
- the anchor tip module points on the side opposite the anchor tip accordingly only one connection side to which a distance module or a wing module can be connected.
- there are also other module forms for example with injection openings or with special additional anchoring components possible.
- the module connection as an axial Plug connection is formed.
- the axial connector allows a torsionally rigid connection of the individual modules at least in the screw-in direction of rotation.
- the connector can, for example, from square or polygonal bolts on one Connection side and corresponding square receiving holes the other connection side of the module.
- a further simplification is achieved according to the invention in that that the first connection side and the second connection side are equally trained. This is preferably because of this achieved that recesses on both connection sides and claws are formed corresponding to each other.
- the non-rotatable connection of the individual modules is similar, so to speak a claw coupling manufactured.
- an installation part is provided which when screwing in for torque transmission with the anchor part is connected via a detachable connection that this at Reaching a predetermined position of the anchor part by the latter is detachable and removable from the ground and that the detachable Connection between the anchor part and the built-in part of the Module connection corresponds. It is therefore not a special coupling part required to remove the torque from the sleeve Installation part towards the anchor part during screwing transfer. Rather, the built-in part can be used directly with a Vane module or a distance module are connected.
- the built-in part is for a particularly good torque transmission formed as a tubular sleeve.
- the tension element is arranged, which itself extends from the anchor part to the floor surface.
- the wing module at least one wing with a quarter, half or entire screw turn. From these segments can also elements with several screw wing turns are put together be, with the screw wings of the individual modules in of the assembled arrangement connect flush. Modules with different sashes can also be used Form and number can be combined.
- the tension element can be a rigid pull rod or a so-called stranded wire, which can be rolled up on a drum. Through the canal but also basically a curable suspension or a other fluid medium can be introduced into the soil.
- the armature tip has an opening, in which the channel flows. In this way, a additionally injected medium in the area of the anchor tip exit the channel and thus an additional strengthening cause.
- a tension element is that a bottom-side End of the tension element attached to an anchor tip module and that the anchor tip module with at least one Screw wing module is connected.
- This manufacturing process is based in particular on the use of one previously described Ground anchor with the individual ground anchor modules.
- the Ground anchors can be assembled by the manufacturer and sold as a finished product or directly from that Users themselves can be composed of the individual modules. In both cases there is a corresponding cost advantage in the manufacture and thus in the use of the ground anchor.
- the method according to the invention for anchoring a Traction element in the floor characterized in that the anchor part according to the required strength of the anchor consisting of an anchor tip module and one or more screw wing modules is put together.
- the anchor part from the anchor tip module and the previously determined number of wing modules and possibly further modules, such as distance modules, composed composed.
- the so composed Ground anchor screwed into the ground using a built-in part.
- a fluid medium such as sand or a curable suspension is introduced.
- the ground anchor according to the invention shown in Figures 1 and 2 10 comprises a central, rod-shaped tension element 5, to the center axis of the bottom-side anchor part 12 and adjoining fitting 16 arranged coaxially are.
- the anchor part 12 is made of individual modules composed.
- An armature tip module 20 with a plate-like, anchor tip tapering downwards in a wedge shape 14 has a conical shape in a cylindrical base plate 24 Bore through which the bottom end of the tension element 5 protrudes.
- a clamping cone 7 that therein arranged bottom end of the tension element 5 in cooperation with the conical bore with the anchor tip module 20 can be wedged. This way, a reliable Connection between the armature tip module 20 and the tension element 5 be ensured in the event of a tensile load.
- Two anchor wing modules are connected to the armature tip module 20 30 each with a sleeve-shaped base body, two screw sashes on the outside 32a, 32b are formed offset from one another by 180 °.
- the Screw wings 32a, 32b each extend by half Winding along the sleeve-shaped base body 38.
- a sleeve-shaped spacing module 40 is provided, the axial length approximately three times the outer diameter of the Screw wing 32a, 32b corresponds to the screw wing module 30.
- the vane modules 30 serve both to generate the Propulsion when screwing the ground anchor into the ground by one Rotary drive, not shown, via the as a sleeve 18th trained mounting part 16 and for anchoring the ground anchor 10 in the bottom. It is a realization of the invention that a axial length of the distance module 40 of about three times the Outside diameter of the screw wing 32a, 32b both good Screw-in function and a firm anchoring guaranteed.
- a second group of identical screw wing modules 30 at the upper end of the distance module 40 is provided, with the upper Vane module 30 that only shown in sections sleeve-shaped mounting part 16 connects.
- the invention can also do other groups of wing modules 30 or individual vane modules 30 in the same or different shape and size to form the anchor part 12 be provided.
- the ground anchor 10 shown by means of a basically known rotating device screwed into the ground.
- the armature tip 14 serves as a drill tip, the soil material in the area of the bore essentially is displaced into the surrounding floor area.
- the screw wings 32a, 32b support the conversion of the rotary movement into one Feed so that the ground anchor resembles a auger can penetrate into the ground.
- Position of the anchor part 12 can be an internal one Channel 19 which through the built-in part 16 and the sleeve-shaped Modules 30, 40 sand or other fluid medium is injected into the ground anchor 10.
- the sand or the medium can have an opening or an opening 22 in the plate-shaped Anchor tip 14 in the area of the ground anchor tip in penetrate the surrounding soil and so for further consolidation the anchorage. Finally, the top Wedging solved by removing the clamping cone 7 and that Installation part 16 are withdrawn from the ground.
