Definitions

  • the invention relates to synchronfundament adopted for anchoring in the ground components according to the preamble of claim 1 and synchronfundamentsysteme according to the preamble of claim 28.
  • Foundation devices for anchoring components such as poles, posts for playground equipment, traffic signs, fences and similar lighter, but also for the founding of significantly heavier components to foundations for electricity pylons, bridge piers and the like, are known in varying degrees.
  • the retaining or plug-in section can be molded into the anchoring section for insertion of the component or can be molded for insertion or attachment or for other attachment ,
  • sleeve-shaped SSfundament that are pointed downwards as for example conical, tapered or frustoconical closed hollow body with the help of a screw provided at their screwed into the soil your firm hold in the receiving soil is improved by the fact that they penetrate into the Soil this displace.
  • the helix provides additional support in the soil.
  • Screw foundation devices which are designed sleeve-like open down, generally provide a good grip in the soil their sleeve shape but also brings with it certain weaknesses that adversely affect especially in foundation facilities for high loads. Although their lateral stability is usually good Even against a nightly twisting they are relatively well secured But since they have a substantially constant axial cross-section with relatively small cross-sectional area, they can - for soft ground or very high support weights - u A movement in the axial direction, in particular the sinking in the soil, oppose too little resistance likewise their resistance against upwardly directed forces, thus for example against the wanton tearing out from the ground, be insufficient.
  • the present application provides a first solution for utilizing the clear width of the sleeve to give the foundation additional support in the ground, in particular to increase the cross-sectional area of the foundation to prevent sinking in the case of a large contact pressure ,
  • this can be effected by providing a closure plug which, after anchoring the sleeve in the ground, can be inserted therethrough and pushed and / or non-rotatably anchored to its lower opening in the direction of the longitudinal axis is and closes this opening in the installed state.
  • the cross-sectional area of the foundation device is thereby increased by the clear inner width of the sleeve, which brings a significant additional securing the ground sleeve against further penetration into the soil with it.
  • the closure stopper is integrally formed with the sleeve and rotated after its screwing into the appropriate position, folded or placed in a similar manner in the sleeve opening and anchored there.
  • the stopper becomes formed in a structurally simple manner as a separate part, which is anchored after screwing the sleeve through the sleeve insertable in the lower opening.
  • the closure plug after installation at least in the direction of the longitudinal axis of the sleeve shear resistant to be connected to the sleeve to oppose by increasing the cross-sectional area of the foundation means their further sinking after their anchoring in the ground additional bearing surface.
  • the closure stopper should preferably at the same time tensile strength and / or rotatably formed on the sleeve anchored to be able to oppose additional resistance to a subsequent rotation of the sleeve or its movement up out of the ground.
  • the closure plug may be a simple plate which is suitably secured in the lower opening of the sleeve, such as screwed.
  • a closure stopper in the form of an upwardly open pot with side walls and a bottom plate, in which the side walls are anchored as a sleeve-like extension of the bottom sleeve at its lower state in the installed state, while the bottom plate so the extended foundation device in the direction of installation closes below.
  • Such a design facilitates the insertion of the closure plug in the bottom sleeve, especially since the side walls can then act as a guide in the sleeve but above all created by the cup-shaped design of the closure plug on the side walls of space for the placement of means for shear-resistant and / or tensile and / or non-rotatable anchoring of the closure plug in the ground.
  • closure plug Since the closure plug is anchored in an appropriate manner to the bottom sleeve, he stabilizes them in addition, by extending them in the result down, by closing the clear width of the sleeve, the footprint of the foundation device as a whole increased and by the rotating lamellae further enlargement of the Contact surfaces to the soil causes, thereby additionally counteracting both any further sinking of the device as well as their wandering or tearing out of the ground.
  • the lamellae when the closure plug with the foundation device in turn is rotatably connected, at the same time their non-rotatable mounting total and thus counteract a reverse rotational movement, which would bring a relaxation in the soil with it this applies all the more, as the lamellae in turn rotate radially and not helically, so that any rotation of the foundation means does not lead to any significant loosening of the plug in the soil, the plug does not follow in particular a screwing easily.
  • the torsional strength of the foundation device already improved by the lamellae as such, ie by their friction in the soil
  • This effect can by a suitable, a rotational movement of the closure plug in the ground further counteracting, the resistance-increasing shape of the slats or the side walls of the closure -Stopfens itself, for example, be improved by interruptions in the slats or by a friction-increasing surface design.
  • the closure plug is in turn screwed or preferably hammered after the insertion or insertion of the sleeve. He can at the same time in the sleeve in their hauling or screwing penetrate soil displaced, thereby causing a further hardening of the soil around the lower portion of the ground socket and thus contribute to a further stabilization of the foundation device in the ground.
  • the bottom plate may additionally comprise means for the non-rotatable anchoring of the closure plug in the ground. These may for example consist in a cross-shaped extension of the bottom plate down.
  • the bottom plate is formed with a downwardly facing in the direction of installation cone or truncated cone-shaped extension, which causes a lateral displacement of the soil and thus its solidification straight in the lateral direction.
  • the bottom plate can also have a direction of installation substantially conical or frustoconical extension with means for rotationally fixed anchoring of the closure plug in the ground.
  • the surface design may have the form of elevations or depressions. It also has a combination of surveys and depressions into account surveys have the disadvantage that they complicate the screwing but they have the advantage that they unfold their full anti-rotation effect immediately depressions have the advantage that they do not inhibit screwing Disadvantage, that they also unfold their full anti-twisting effect only gradually as the soil and, above all, the fouling (roots) are embedded in them.
  • the elevations and / or depressions can be configured, for example, as tooth-like knurls running in the circumferential direction of the sleeve, possibly also the helical coil. However, they can also be designed, for example, as scales running in the circumferential direction.
  • the scales will be counteracting the unscrewing They then stand, even if they protrude from the surface, the screwing of the foundation device barely.
  • the anti-twist device should be designed to be particularly effective if the scales are undercut, because then there root system and the like can anchor very well.
  • the surface design can be continued into the area of the foundation device into which the This would be in a foundation device in which the component is plugged, the remote part of the outer shell of the foundation device If the insertion of the component into the sleeve of the foundation device comes into consideration, could also its inner surface to secure a tight clamping fit be designed according to the component to be anchored.
  • a fferably a sleeve-like body having an anchoring of a component in the ground serving anchoring portion and the component receiving holding or plug portion
  • the anchoring portion as a displacement body formed with at least one conical region and at least over a part its upper part is provided with a helical screw for screwing into the soil, on the anchoring section above its conical area an upper part is formed, which in at least one cutting plane running through its longitudinal axis, at least outside, at least one zone of larger diameter than the diameter of the region acting as a clearing area Base of the conical region (which is the circular base of the cone), so that when screwing the foundation means by displacement of the soil in the region between the at least one zone of larger diameter and between the soil and the wall of the upper part at least one fillable gap is formed, can be reliably secured by the backfilling of the anchoring portion against subsequent rotation.
  • This embodiment is preferred over a hereinafter also claimed embodiment in which the cross section of the upper part of the anchoring portion has smaller dimensions than the (circular) cross section of the base of the conical region, for example because the upper part is polygonal in cross-section and the corners of the polygon In cross-section do not protrude beyond the diameter of the base of the conical area In such a form, when screwing into the soil, although one or more gaps between the soil and upper part also form .
  • the upper part of the anchoring section preferably has at least one zone of larger diameter than the diameter of the (circular) base of the conical section.
  • the zone of larger diameter may be a bulge in the simplest embodiment over the length of a substantially cylindrical extension of the (circular) cone base of the conical region, which when driving the foundation device by displacing the soil an almost all-round fillable gap between the upper part of the anchoring portion and forms the soil.
  • the upper part of the anchoring section will preferably have two or more zones of larger diameter distributed uniformly over its circumference. It will preferably be formed as a polygon, in which at least one of the edges, but preferably all edges lie in a zone of larger diameter.
  • the polygon can, for example, have two opposite edges or be formed in cross-section triangular, rectangular, square or with a different number of edges Er can then form a corresponding plurality of fillable columns when screwing.
  • the sides of the polygon can be deformed inwards.
  • At least one of the edges of the polygon can be sawtooth-deformed, preferably in counter to the insertion direction directed toothing.
  • this holding or plugging portion can in the simplest case on the anchoring portion itself, but here - because the anchoring portion is completely submerged in use in the ground - only as an inner contour for insertion of the component (rod, post, masts or the like.) Be formed in the upper part of the anchoring portion.
  • a holding or plugging section can also be provided integrally connected to the upper part of the anchoring portion or connectable holding part, which - if it is designed as a separate component - can also be plugged into a correspondingly shaped receptacle of the upper part, screwed o
  • the holding part can then in turn have a receptacle as an inner contour for insertion or as an outer contour for attaching the component.
  • the receptacle can be designed as an inner contour in its cross section, in particular the cross section of the outer contour, that is not only round, but also as polygonal (triangular, square, etc) for receiving a component with a corresponding cross section.
  • special designs of the wall such as a deformation the sides of the polygon inside at the same time as storage means, for example, as a clamping means for the component to be stored can be used.
  • the cross-section of the upper part of the anchoring portion has at most the same maximum maximum dimensions as the (circular) cross-section of the base of the conical region, whereby recesses cause corresponding gaps between soil and upper part when screwed in.
  • These foundation devices also have a sleeve-like body on, which in turn has an anchorage in the ground serving anchoring portion and a component receiving holding or plug-in portion.
  • the anchoring portion is designed as a displacement body with at least one conical region with a circular cross-section and is provided at least over part of its length with a thread for screwing into the soil.
  • an upper part is formed on the anchoring section above the conical region, whose cross-section has at least two separate regions, which are retracted relative to the circular cross-section of the base of the conical region in the direction of the longitudinal axis.
  • This causes the soil during the screwing of the foundation device is displaced by the conical region and thereby at least one fillable gap between the soil and the wall of the shell is formed at the retracted areas By filling these gaps, the anchoring portion is reliably secured against subsequent rotation.
  • the term drawn-in region should be understood to mean that, unlike the circular cross-section of the base of the conical region, ie the circular envelope, only certain regions in the form of noses, corners or protruding cam-like shapes are formed there, the remaining region, however, with respect to FIG Circular envelope is retracted, that is offset inward in the direction of the longitudinal axis, so that virtually one or more cavities arise in the ground.
  • a single nose on one side of the cross section may extend to the circular envelope, which is surrounded on both sides with retracted areas, which of course do not necessarily have to extend over half of the circumference, but for example, only over about a quarter of the circumference.
  • an asymmetrical profile would indeed arise, but such a profile could be important, for example, if, on the one hand, an anti-rotation device is used If, on the other hand, for example, wind pressure is to be absorbed on a device fastened in the fastening device of primarily one side.
  • the invention further relates to a foundation system for fastening components, in particular of rods, posts, masts or the like in the ground, consisting of an anchorage in the ground serving foundation device according to claims 17 to 27 and a filler for filling the screwing in the foundation device resulting fillable columns.
  • the filling material used depends on the type of pending substrate, the static requirements for the device, its dimensioning and the nature of the material. Suitable filling materials are, in particular, concrete or granular materials of uniform or different grain size, in particular sand or split, optionally with addition can be used by the PH value changing substances.
  • concrete as a more elaborate filling material with a suitable substrate ensures a particularly secure anchoring.
  • sufficient split is recommended, especially for medium requirements, because it is inexpensive, easy to access and easy to handle and by its good flowability a simple post consolidation of the environment Due to its structure, it creates, in particular in connection with the shaping of the anchoring section, by wedging a very good protection against undesired subsequent twisting, in particular a reverse rotation of the screwed device He also contributes to the corrosion protection of the foundation device, because he the PH value in the environment of the device in the soil favorably influenced, so that in itself possible additions to the PH value changing substances to the filler are usually unnecessary.
