Definitions

  • the invention relates to a fastening system for fastening a rod or post-shaped object in the ground with a screwed into the ground sleeve-like receiving part, which is provided at least over part of its length with an external thread on its outer periphery and in the attached state, an end portion of the rod or receives post-shaped object and surrounds its circumference at least in sections, with a screw-in, which has a dimensionally stable fitting core on which the receiving part for the purpose of screwing into the ground rotationally attachable, according to the preamble of claim 1.
  • the invention further relates to an optionally required filling material and corresponding fastening methods.
  • Such a fastening system show, for example, the DE 199 60 854 A1 and DE 102 14 083 A1 , It is used for permanent or temporary installation of posts, poles and the like, as they are required for fences, information signs and boards, spin dryers in gardens and buildings of any kind made of wood.
  • Such fastening systems are suitable for soils of all kinds, including scree floors, gravel beds, sandy and loamy soils, not only in the plane but also on dams and embankments.
  • the sleeve-like receiving part may be (an impact sleeve or) a threaded sleeve, which is also referred to as a ground dowel or ground screw and is meant exclusively in the present case, when it is spoken of the "receiving part".
  • This ground dowel / ground screw (hereinafter: “receiving part") has in example mentioned a cup-shaped filling section. After screwing the female part into the ground the rod-shaped object is inserted into the filling portion, which surrounds the lower end portion of the rod-shaped object at a distance. The rod-shaped object can then be aligned vertically, whereby directional deviations that have arisen during insertion of the receiving part into the ground, can be compensated. Then, the annulus between the lower end of the rod-shaped article and the cup-shaped filling portion is filled with the filling material.
  • the filler may be granular, such as granules, hard sand, split or rock material. But also an elastic plastic material comes into question, as well as a solidifying liquid mass, especially concrete.
  • the use of a granular material has the advantage that the entire fastening device can be quickly removed again, for. For example, for temporary structures at exhibitions and fairs.
  • Said, designed as a screw sleeve fastening system corresponds with its cup-shaped filling portion in the receiving part in its design largely the well-known ground dowels with own receiving section at the top, in which the rod-shaped object is used directly, without interposition of a filling material in the receiving portion and secured there.
  • ground anchors are known in many embodiments; an example shows the DE 93 13 258 U1 , They usually consist of a lower threaded portion and the upper receiving portion, between which there may be a conical displacement portion. But there are also two parts in the sense that a retaining part (to be screwed into the ground anchoring part ( DE 202 20 515 U1 ; DE 203 04 257 U1 ) or an extension sleeve ( DE 200 00 183 U 1 ) can be attached as a separate component for receiving the rod, post etc. or the anchoring part itself can be divided ( DE 203 12 771 U1 ).
  • ground anchors are relatively solid. In fact, they must not only absorb the forces which the mast or post impinges on them when directly attached to them. she are especially heavily loaded when screwing into the ground. This is especially true when a manually or mechanically operated screwing tool engages at its upper end, for example with a bolt inserted transversely through the receiving portion, as is often suggested ( DE 93 13 258 U1 ). The high local load when initiating the torque can lead to a deformation of the ground dowel or receiving part, if their execution is not massive enough.
  • the cited document also proposes to provide the insertion tool for screwing this receiving part with a dimensionally stable fitting core, which rests largely or completely on the inner contour of the receiving part and thus largely fills and supports during screwing and thus by positive, in particular frictional adjustment in the Sense of Einfens the forces required for screwing and / or torque over a large area on the receiving part and so the only serving as formwork receiving part granted only its required for introduction into the ground dimensional stability.
  • the receiving part then serves only in the form of a formwork to hold the filler together, to diffuse into the surrounding soil and thus to prevent loosening of the anchorage and to support a consolidating setting of the filling material.
  • the receiving part is supported even in this installed state to the outside of the solidifying soil, which in turn can not compress the receiving part, because its interior is then filled and stiffened by the filling material and the lower end of the rod-shaped part.
  • Object of the present invention is therefore to provide a fastening system and the associated items as well as a method that avoids unnecessary costs that it with one or a small number of Einschraubtechnikmaschineen or passport cores and a few different receiving parts the widest possible range of Covering options.
  • the invention provides the solution in the modular construction of the fastening system by offering a plurality of different sleeve-shaped receiving elements, of which a smaller or larger number can be put together to the receiving part of the required dimensioning (length) depending on the requirements made in the individual case.
  • these will be interchangeable receiving elements of a single same cross section, in which different load specifications only by juxtaposing a correspondingly larger number of receiving elements and correspondingly longer design of the receiving part can be taken into account.
  • different load specifications only by juxtaposing a correspondingly larger number of receiving elements and correspondingly longer design of the receiving part can be taken into account.
  • groups of each combinable holding elements of different cross sections can be made available.
  • the design according to the invention is based on the finding that the modular design of such a fastening system allows this a broader field of application while saving storage and transport costs.
  • the invention is based on the finding that even those by itself less stable receiving elements, if they are fitted accurately or substantially accurately to a common mating core and screwed into the ground, thereby supported and held in the same way as a single , contiguous receiving part, so they can be designed just as material-saving as a larger, coherent receiving part.
  • the receiving elements are connected to each other. Because they are after their screwing into the soil, in which they are fixed by the mating core in position to each other after the removal of the mating core and the setting of the rod or post and filling the filler in the once occupied position sustainable determined.
  • each receiving element will be equipped with an external thread.
  • receiving elements it can be dispensed with in individual, such as a placed between two receiving elements with threaded receiving element, even on an external thread. This is conceivable in the same way for a receiving element which is provided only as an upper closing element to the earth's surface, in particular when it is connected to the adjacent receiving element.
  • the modular design of the receiving part is suitable for all known forms of screw foundations, regardless of whether they are cylindrical open at the bottom, tapered towards the lower end tapered or truncated cone shaped with lower opening.
  • the simplest is the downwardly open, cylindrical shape, since it requires only one, namely a cylindrical sleeve-like receiving element, which can be assembled in the necessary majority to the correspondingly sized holding part.
  • the receiving part can also be formed from at least one sleeve-like receiving element cylindrical contour and a receiving element with at least partially tapered or frusto-conical contour in the installation direction with external thread, which requires that a corresponding module is provided.
  • the receiving part can be formed from a sleeve-like receiving element cylindrical contour and / or a receiving element cone or frusto-conical contour and a receiving element as the upper closing element with or without external thread, which requires a corresponding element as a further element.
  • the fastening system according to the invention requires a single (cylindrical) receiving element and, with a maximum of five different receiving elements (cylindrical receiving element with and without external thread, pointed conical, frustoconical receiving element and upper closing element) of the same cross section, provides a broad spectrum for a wide range of load specifications of possible combinations.
  • the receiving elements are plugged for screwing into the soil on the common mating core, and are firmly anchored in their position after screwing in the ground, no connection of the receiving elements with each other.
  • a non-rotatable or a tensile and shear-resistant connection of the receiving elements with each other if desired, to achieve with simple means.
  • the non-rotatable connection results, for example, without further ado, when the receiving elements in the positive connection, approximately in cross-section as a polygon, are plugged into each other.
  • the tensile and shear-resistant connection can be realized in a simple manner by clip connections in the region of the connector.
  • the non-rotatable attachability of the sleeve-like receiving elements on the passport core can be accomplished in different ways.
  • a frictional connection which can also be generated or reinforced by a hydraulic expansion of the dowel core, in particular a form fit comes into consideration.
  • ribs may be formed on the inside of the receiving elements, which extend in the longitudinal direction of the receiving elements and engage in corresponding longitudinal grooves of the fitting core.
  • these two variants assume that the receiving elements have a sufficient inherent rigidity, that is, that they do not require the more or less full-surface support through the fitting core when screwing. Then, however, they also have the advantage that by appropriate different dimensioning of the ribs or passages under certain circumstances also receiving parts / receiving elements of different dimensions (different outer diameter) can be operated with one and the same Einschraubtechnikmaschine.
  • the receiving elements themselves may have an at least inwardly polygonal or a similar cross section, which corresponds to the outer cross section of the fitting core.
  • This variant has the advantage that the fitting core can support the correspondingly lightly constructed receiving part / receiving element over its entire surface.
  • the wall of the receiving element itself forms the inner cross-section of the receiving element corresponding to the outer cross-section of the fitting core, this full-surface contact should be ensured by the receiving parts - be they plugged together or loose - at least for receiving elements which require a full contact of the fitting core for screwing mounted on the dowel core - over the entire length of the formed receiving part (with the exception of one area tapered inner contour in a cone or truncated cone-shaped receiving element) have a substantially continuous inner cross-section. Only then can it be ensured that a screwing-in tool with a dimensionally stable fitting core corresponding outer contour can bring about a screwing of the receiving parts placed thereon into the ground with the greatest possible uniform distribution of the forces acting thereon.
  • an area of tapered inner contour in a conical or frusto-conical receiving element merely takes into account the fact that, in the conical region, there is naturally no “continuously variable cross-section".
  • the screwing-in tool or its mating core should, of course, also be adapted as far as possible in its outer contour to the inner contour of the cone-shaped or truncated-cone-shaped receiving element in this area, so that this part of a receiving element also contacts the mating core as fully as possible can be brought, the opposing shapes are to be avoided in any case.
  • receiving elements and fitting core For the corresponding positive interpretation of receiving elements and fitting core, of course, other than the previously described designs come into consideration. In any case, it must be ensured with them, however, that the receiving elements in the desired type, number and order on the fitting core are plugged so that the fitting core passes through each of the receiving elements, they coaxially aligned rotationally fixed, possibly even with the largest possible transmission of the Screwing forces occurring holds, and that the dowel core can be withdrawn after screwing the receiving elements in a simple manner from the screw foundation.
  • the outer contour of the dimensionally stable fitting core of the screw-in tool corresponds to the inner contour of the receiving elements or their passages.
  • the coupling between the sleeve-like receiving elements and the dowel core can then be carried out, for example, in such a way that - as in DE 10 2005 023 465 B3 described in more detail - formed on the outer circumference of the sleeve-like receiving elements threads to the interior of the receiving element are open and form a helical profiling, which is adapted to an external thread, which is formed on the outer circumference of the dowel core, wherein the engagement and disengagement of receiving elements and Pass core is made by oppositely directed rotational movements.
  • the fastening system according to the invention can only develop its full benefits if the dimensionally stable fitting core has a length corresponding to the maximum number or the total length of the maximum number of receiving elements to be combined in a practical use to a receiving part.
  • a thin-walled receiving element is naturally mechanically most endangered when it is introduced into the ground in the region of its penetrating into the ground tip. Therefore, it can further be provided that the sleeve-like receiving elements form an insert body with inserted fitting core together with this insert body which ends in its direction of the ground facing in a cone which is partially or completely formed by the sleeve-like receiving elements in the direction of insertion passport core. After insertion of the insert body in the ground of the fitting core is removed again, so that only serve as formwork receiving elements remain in the ground.
  • the dowel core of the insertion tool thus engages through the hollow sleeve-like receiving element until it projects with the tip of its cone down from the lower in the screw-in receiving element.
  • the insert body consisting of the fitting core and the receiving elements penetrates into the ground with the tip of the fitting core first. Since the receiving part or its elements is usually a mass portion that can only be used once or are, however, the insertion tool can be used over and over again, it is worthwhile to form this insertion tool of a resistant material in high quality, so that it with its tip can serve many times as an indenter into the ground.
  • the lower sleeve-like receiving element in the direction of screwing in its direction of engagement facing the ground ends in a cone whose tip region consists of a reinforced material.
  • the closed tip of the sleeve-like receiving element may be made of a different plastic than the rest of the receiving element, or the tip may be reinforced by a fiber material. Even a tip made of metal on an otherwise plastic receiving element is conceivable. Since the sleeve-like receiving element due to its lower thickness in total is cheaper in any case, the associated with this somewhat more effort can be more than justified.
  • the materials suitable for the receiving elements and the fitting core of the insertion tool are based on the particular application.
  • the fitting core of the insertion tool consists of a metal material, preferably of steel, while for the sleeve-like receiving elements in each case a plastic comes into question.
  • Suitable plastics are, for example, polyamides, polypropylenes, polyethylenes and polystyrenes, which are listed in the here Sequence at the same time mean an increasing life of the receiving elements in the ground.
  • a filling material is part of the fastening system
  • free-flowing materials such as sand, split or quarry stone, but also granules, for example of plastic, are particularly suitable for this purpose.
  • concrete can also be used.
  • the invention is also the formable from a plurality of receiving elements, screwed into the ground, sleeve-like receiving part for attaching a rod or post-shaped object in the ground and the associated Einschraubtechnikmaschine for such a fastening system and finally the fastening method to be used in the application of the fastening system, characterized in the case of mounting elements of sufficient inherent rigidity, which require no filling material, by the method steps according to claim 19, otherwise by the method steps according to claim 20:
