Definitions
- the invention relates to a method and a device for anchoring ground anchors for rod-shaped objects, in particular posts and a ground dowel system for performing the same.
- a ground socket which serves for quickly exciting and interchangeable receiving posts for traffic signs. It is a concreting sleeve of a cast body. In its upper part there is a thread under which the seat of a sleeve-like clamping ring is located. After the seal is inserted, a kind of hollow plug is loosely screwed into the thread. After setting in concrete and drying, the post is inserted into the hole of the hollow stopper in abutment. The hollow stopper is then tightened with a wrench over the wrench flats, pressing the clamping ring against the post and securing it.
- ground dowels Apart from the attachment of a post in the ground dowel there is the problem that soil dowels of different lengths and shapes are needed. Furthermore, in a subsoil in which many supply lines run, a ground dowel should not damage them during insertion. Finally, since the ground dowels are cast in hardening material, such as concrete, the casting of viscous material promoting same configuration desired so that when introducing the anchor into the concrete no stability of the encapsulation affecting air bubbles remain in the concrete, but the concrete bubbles connects to the bottom tube of the anchor. In addition, the posts from the ground dowels should be reversibly removable - for example, if the post for work in the way or should be introduced only temporarily or damaged / kinked. Another problem is the orientation of a dowel, so that a post can be introduced vertically - this was previously problematic, as frequently deflecting objects prevented the vertical insertion when driving a dowel into the unpaved surface.
- the inventive method and the ground dowel system is an aligned introduction of ground dowels with the least amount of mortar-like material adapted to a variety of requirements - such as the surface texture - with an effective, cost-effective operation and a modular device, the anchor system, in a compact and flush construction ,
- a particular advantage of the invention is its aesthetically pleasing appearance, which is achieved by the use of pre-hole templates and excavation templates which avoid damaging the bore edge of the ceiling.
- the pot of the dowel closes in an appealing manner with the hole in the ceiling, because of the templates damage to the ceiling by pre-puncture or further spaces is avoided.
- the invention thus relates to a method for anchoring ground dowels for rod-shaped objects (4), in floors with a fixed surface (ceiling) (52) by means of a ground dowel system (1) with a bottom tube (2) for receiving a post portion, the cup-like Mounting flange (7) in the form of a pot open in the direction of the ground end of the ground anchor with a bottom (15) and a vertical annular wall (16), screw sleeves in the bottom of the pot (15), discharge openings (17) and has a closed end, with the steps : Making a defined circular cutout in the ceiling (52); Digging a shaft (51) in the bottom (50) below the circular section of the ceiling (52) whose cross section corresponds to the circular cutout in the ceiling (52) and whose length is sufficient for the bottom tube in the shaft is free to pivot; wherein the diameter of the circular section in the ceiling (52) by 1-10%, preferably 3- 6% greater than the diameter of the cup-like mounting flange (7), so that the dowel in the shaft (51) by 10
- the dowel can be cast with little hardening material, because it is no concrete / mortar excess necessary.
- the concrete / mortar often used as a viscous material is not an environmentally friendly material and should therefore be used as little as necessary, what the invention allows.
- the alignment of the anchor can be controlled in the usual way by means of a spirit level or a dragonfly on a rod inserted into the post opening.
- the dowel is pivoted in the manner of a self-aligning bearing against the inner wall of the ceiling circular cutout and so vertically aligned.
- the dowel can also be rotated within the guide formed by the ceiling circular cutout, if rectangular piles are to be fastened with a preferred direction - for example, in traffic signs.
- a circular cutout of defined size is made in the ceiling of the fixed floor, the is only slightly larger than the diameter of the dowel flange, the inner wall of the circular cutout can act as a fulcrum in aligning the bottom tube introduced into a well dug below the circular cutout and prevent sinking of the flange in the moist hardenable material.
- the floor pipe may be extended prior to insertion into the hoistway by at least one extension pipe having a bottom pipe earth end receiving opening and an extension pipe earth end is dug deeper according to the geometry of the extended bottom tube, wherein the shaft (51) is dug longer correspondingly longer than the extended bottom tube (2, 20).
- only a basic dowel of predetermined length needs to be made, which can be modularly extended by attachable extension tubes.
- the bottom tube (2) and / or the extension tube e (20) retaining means which make it difficult to move, twisting and pulling the ground anchor (1) against the soft material and prevent hardened material.
- posts After setting in / pouring in the ground anchor, posts can be fixed in the anchor.
- a post mounting with: a clamping ring (11) for the post and on the clamping ring (11) against the mounting flange (7) unscrewed clamping plate (8) with post opening and clamping screw holes (22); Inserting a post end through the clamping ring (11) and the clamping plate post opening (10) in the bottom tube opening, Tightening the clamping screws (9) against the screw sleeves in the mounting flange (7) under compression of the clamping ring (12) under adhesion to the post (30) instead.
- This tensioner allows easy replacement of the posts and is robust to rear-end collisions - i. only the clamping device is deformed - the anchor remains unharmed.
- a cover plate with screw holes (24) can be screwed onto the flange (7) while covering the post opening, if presently. no post is included in the dowel.
- a particular advantage of the invention is that now the introduction of the posts is repeatable and automatable possible.
- normative conditions of the post attachment can be created, as they are, for example, desired for participating in the road posts (eg traffic signs) or for uniform design of street furniture.
- the bottom tube earth termination end is integral with the tube (2) and has a streamlined taper which is closed by forming into a round closed end or bent, cut unshaped bottom tube sections, or by a separate, end-capped, streamlined cap (40) is formed.
- the at least one bottom pipe (2) and / or the extension pipe (20) can have flow-favorable anchoring elevations.
- ground anchors are placed under the least possible burden on the environment by a repeatable approach and easily adaptable to changing, to be absorbed by them post and similar rod-shaped objects or loads to be absorbed without consuming to store.
- floor pipes of a ground anchor can be provided with extension pipes of different lengths and possibly interchangeable tails, it is possible to provide a ground dowel system that can be easily adapted to local conditions and soil conditions.
- extension tube at the ground end with a protruding anchoring bead for improved anchoring.
- shaft 51 can be extended conically downward during its excavation, so that even the cured viscous material itself forms a second anchoring bead or cone and the overall system receives a high pull-out strength.
- Possible materials for the system are corrosion-resistant, elastic materials, i.a. Steel, cast iron, sintered metal, aluminum, brass and high-strength plastics.
- the shaft can be easily produced, as well as the cast-in anchors may also be easily removed together with the concrete from the ground - for example by means of a corresponding Drill bit or cup chisel.
- An alignment of the ground dowel against the inner wall of the ceiling circular cut is possible in wet concrete effortlessly and with little effort - both in terms of height, as well as the direction and orientation of the anchor, if rectangular profiles are to be used.
- Fig. 1 For example, there is schematically illustrated a method of aligning a ground anchor in a fixed ground. It is first made a circular cut from the ceiling 52 of a paved surface by means of a drill bit. In the next step, a slot 51 is dug under the circular cutout of approximately the same diameter as the circular cutout and approximately the length of the ground anchor. In the shaft then curable material - in this case, liquid concrete - filled. It is important to ensure that as much concrete is filled as it corresponds to the shaft volume minus the anchor volume. In this soft concrete Now a ground dowel 1 is pressed until its mounting flange 7 is in the ceiling 52.
- bottom tube 2 displaces the concrete in the shaft, which flows upwards in the shaft, fills the shaft 51 up to the ceiling 52 and optionally swells out somewhat over the ceiling.
- the concrete also flows around projections on the bottom tube 2, prevent the hardening of the concrete extraction and / or rotation of the bottom tube 2 and the bottom anchor 1.
- An excess amount of concrete can be removed or leak through any existing discharge openings 26 in the cup-like mounting flange 7 and removed there.
- the ground dowel 1 thus introduced into the moist concrete is now aligned perpendicularly in the shaft - for example by means of a known, in the bottom tube pluggable alignment with a circular level or spirit level (not shown).
- a circular level or spirit level not shown.
- the tough flowing concrete stabilizes the new position of the ground anchor 1 and is strengthened by the curing.
- 7 functional parts on the ground dowel flange such as a clamping device or a cover 60.

- the clamping plate 8 is slightly angled in this embodiment for stiffening. It has countersunk holes for screws, so that after screwing in the screws, a flat surface is created. Above this is the rod-shaped object 4, which is to be fastened.
- the clamping plate 8 is fixed with four screws 11 on the flange 7. In this case, the clamping ring 13 is activated and clamps the rod-shaped object.
- Fig. 2 shows a ground anchor for use in the process of the invention in an exploded view with flange and clamping plate lot and an extension tube with a tip.
- the clamping and reinforcing ring 13 is formed as a symmetrical double cone and is mounted in a conical shape of the flange inner opening.
- the expanded bottom tube 2 and the clamping and reinforcing ring 13 form in the uppermost region of the flange 7, ie where the greatest bending forces occur, a stable stiffening. This stiffening transfers to the area of Clamping plate 8, the passage only a few millimeters from the surface of the mounting flange 7, whereby the lever arm when bending the rod-shaped article 4 is kept as small as possible.
- the clamping plate 8 is stiffened by a bend and has the complete bottom cover and maximum stability the diameter of the outer contour of the flange 7. It clearly shows how the ending in a rounded tip ground anchor 1 in a widened in the upper region extension tube 20, in this embodiment also has a rounded tip produced by forming, can be introduced and thus extends the bottom tube 2.
- Fig. 3 shows a detail of the device for fixing rod-shaped objects 4 after Fig. 1 in the closed state on average.
- the biconical clamping and reinforcing ring 11 is approximately flush with the top of the clamping plate 8.
- the recessed screws 9 are as in Fig. 2 tightened so that the angled clamping plate 8 is seated on the flange, the clamping plate 8 receives a bias in itself by the tightened screw.
- Fig. 4 is shown a further embodiment of extension tubes - here with a separately formed streamlined cap 40 with a circumferential Anank ceremoniesswulst 42, which can be screwed onto the extension tube.
- Fig. 5 shows an extension tube with attached cap 40, wherein the connection to the extension tube should not be limited to screwing - it can be attached in any other way - eg. By welding, soldering, press fit.
- Fig. 5a 1 schematically shows the manufacture of an extension tube with molded cap 40, wherein a round closed end of the extension tube is made by cutting triangular cutouts and then forming by pressing the cut extension tube end against a mold.
- Fig. 6 represents another part of the ground dowel system 1 according to the invention, the cover plate 60.
- the embodiment of a cover plate 60 shown here by way of example is for secure covering of the ground dowel opening when the ground dowel 1 is not required for post 4, provided. It is slightly curved and has in this embodiment elevations on the surface that prevent slipping on the cover plate 60. Their holes with recesses allow the screwing of countersunk screws, which avoids stumbling over the dowel covered in this way and a visually appealing impression of the area equipped with the ground dowel with cover surface is achieved.

Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Verankern von Bodendübeln für stabförmige Gegenstände, insbesondere Pfosten sowie ein Bodendübelsystem zur Durchführung desselben.The invention relates to a method and a device for anchoring ground anchors for rod-shaped objects, in particular posts and a ground dowel system for performing the same.
Die Verwendung von Bodendübeln und Betonierhülsen ist weit verbreitet. Bekannt sind Bodendübel nach
Aus der
Ferner ist aus dem Prospekt der Firma Dambach, D-76571 Gaggenau eine Bodenhülse bekannt, die zur schnell spannenden und auswechselbaren Aufnahme von Pfosten für Verkehrszeichen dient. Es handelt sich dabei um eine Betonierhülse aus einem Gußkörper. In ihrem oberen Bereich befindet sich ein Gewinde, unter dem sich der Sitz eines manschettenartigen Spannrings befindet. Nach eingelegter Dichtung wird eine Art Hohlstopfen lose in das Gewinde eingeschraubt. Nach Einbetonieren und Austrocknen wird der Pfosten auf Anschlag in das Loch des Hohlstopfens eingeführt. Der Hohlstopfen wird dann mit einem Schraubenschlüssel über die Schlüsselflächen angezogen, wobei sich der Spannring an den Pfosten anpresst und diesen sichert.Furthermore, from the prospectus of the company Dambach, D-76571 Gaggenau a ground socket is known, which serves for quickly exciting and interchangeable receiving posts for traffic signs. It is a concreting sleeve of a cast body. In its upper part there is a thread under which the seat of a sleeve-like clamping ring is located. After the seal is inserted, a kind of hollow plug is loosely screwed into the thread. After setting in concrete and drying, the post is inserted into the hole of the hollow stopper in abutment. The hollow stopper is then tightened with a wrench over the wrench flats, pressing the clamping ring against the post and securing it.
Die Bodenfundamente und Betonierhülsen haben Nachteilelnsbesondere ist die Verwendung von unnötig viel Beton zu bemängeln, was den Boden versiegelt und zu Schwierigkeiten beim Entfernen der Einrichtung führt.The floor foundations and concreting sleeves have disadvantages. In particular, the use of unnecessarily much concrete is to be criticized, which seals the floor and leads to difficulties in removing the device.
Bei alten Vorrichtungen der Firma Gebr. Sträb nach
Bei der Bodenhülse von Dambach mit Kunststoff- bzw. Gummi-Spannring führt ein Aufprall zu einem Abplatzen des Randes der Stopfmutter und in schwereren Fällen zu einem Reißen des Gußkörpers. Ein weiterer Nachteil ist, daß Kunststoffe altern und fließen, ein Nachteil, der besonders dann auftritt, wenn Torsionskräfte auf den Pfosten einwirken oder große Temperaturschwankungen auftreten.In Dambach's ground sleeve with plastic or rubber tension ring, an impact will cause the edge of the stuffing nut to flake off and, in more severe cases, crack the cast body. Another disadvantage is that plastics age and flow, a disadvantage that occurs especially when torsional forces act on the posts or large temperature variations occur.
Abgesehen von der Befestigung eines Pfostens im Bodendübel besteht das Problem, dass Bodendübel unterschiedlicher Längen und Formen benötigt werden. Ferner soll bei einem Untergrund, in dem viele Versorgungsleitungen verlaufen, ein Bodendübel diese beim Einbringen nicht beschädigen. Schließlich ist, da die Bodendübel in aushärtendem Material, wie Beton, vergossen werden, eine das Vergießen mit viskosem Material fördernde Ausgestaltung desselben erwünscht, damit beim Einbringen des Dübels in den Beton keine die Stabilität des Vergusses beeinträchtigenden Luftblasen im Beton verbleiben, sondern der Beton blasenfrei am Bodenrohr des Dübels anschließt. Zudem sollen die Pfosten aus den Bodendübeln reversibel herausnehmbar sein - bspw. falls der Pfosten für Arbeiten im Wege ist oder nur temporär eingebracht werden soll oder beschädigt/abgeknickt ist. Ein weiteres Problem ist die Ausrichtung eines Dübels, damit ein Pfosten senkrecht eingebracht werden kann - dies war bisher problematisch, da beim Einschlagen eines Dübels in den unbefestigten Untergrund häufig ablenkende Gegenstände das senkrechte Einbringen verhinderten.Apart from the attachment of a post in the ground dowel there is the problem that soil dowels of different lengths and shapes are needed. Furthermore, in a subsoil in which many supply lines run, a ground dowel should not damage them during insertion. Finally, since the ground dowels are cast in hardening material, such as concrete, the casting of viscous material promoting same configuration desired so that when introducing the anchor into the concrete no stability of the encapsulation affecting air bubbles remain in the concrete, but the concrete bubbles connects to the bottom tube of the anchor. In addition, the posts from the ground dowels should be reversibly removable - for example, if the post for work in the way or should be introduced only temporarily or damaged / kinked. Another problem is the orientation of a dowel, so that a post can be introduced vertically - this was previously problematic, as frequently deflecting objects prevented the vertical insertion when driving a dowel into the unpaved surface.
Ein gerichtetes Einbringen der einschlagbaren Bodendübel war schwierig und erforderte lange Ausrichtvorgänge, da die bekannten Bodendübel aufgrund von Reibung im Untergrund schlecht exakt auszurichten waren.A directed introduction of the knock-down ground dowels was difficult and required long alignment operations, since the known ground dowels were difficult to align due to friction in the ground.
Diese Probleme wurden bisher mit Einzellösungen angegangen. Für jedes Teilproblem wurden spezielle Dübelgestaltungen vorgesehen, die von den Bauhöfen und Unternehmen auf Vorrat gehalten werden mußten.These problems have so far been tackled with individual solutions. For each sub-problem special dowel designs were provided, which had to be kept by the construction yards and companies in stock.
Es ist daher Aufgabe der Erfindung, ein Verfahren und ein dafür ausgelegtes Bodendübelsystem zum ausgerichteten Einbringen von Bodendübeln sowie dafür ein ausgelegtes Bodendübelsystem zu schaffen, welches die Nachteile des Standes der Technik vermeidet.It is therefore an object of the invention to provide a method and a designed ground anchor system for the aligned introduction of ground dowels and for a designed ground dowel system, which avoids the disadvantages of the prior art.
Die Aufgabe wird erfindungsgemäß durch das Verfahren nach Anspruch 1, die Vorrichtung nach Anspruch 10 , das System nach Patentanspruch 7 und die Vorrichtung nach Anspruch 11 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den abhängigen Ansprüchen.The object is achieved by the method according to
Durch das erfindungsgemäße Vorgehen kann nun eine quantifizierbare Menge aushärtenden viskosen Materials, wie Flüssigbeton verwendet werden und unnötiger Betoneinsatz vermieden werden. Durch den Auftrieb des Dübels im feuchten aushärtenden Material nach dem Archimedes'schen Prinzip des Auftriebes gleich dem Gewicht der verdrängten Flüssigkeitsenge kann der Dübel leicht mittels eines Stabes oder leichten Schlägen bündig zur Oberflache eingetrieben werden. Infolge der Führung des topfartigen Befestigungsflansches im Kreisausschnitt der Decke und dem sich dazwischen befindlichen viskosen Material, kann das Bodenrohr , analog der Funktion eines Pendellagers, hier mit viskosem Ausgleichsmaterial, leicht pendelartig schwenkausgerichtet und in die Vertikale gebracht werden. Besonders günstig ist es wenn dieses Eindrücken nach unten und das Ausrichten im Kreisausschnitt mit einen zentrierenden Stab mit einer Dosenlibelle am oberen Ende erfolgt und so des Eindrücken und das Ausrichten gleichzeitig erfolgt.. Dabei wirkt der Rand der aufgebohrten Decke als Drehpunkt und der Dübel verbleibt aufgrund des viskosen Materials bis zu dessen Aushärten in der einmal eingestellten Lage. Der Auftrieb des Dübels mit seinem Hohlraum und seiner Adhäsionskraft am Beton sind in einem solchen Verhältnis zum weichen Beton, daß des eingedrückte Dübel stets in der eingedrückten Lage verharrt, sich jedoch beim Ausrichten bewegt. Mit der Verwendung der Schablonen (56) und (57) kann der Aushub im unteren Bereich so gestaltet werden, daß Betonüberschuß vermieden wird und gleichzeitig der Aushub mit gängigem Werkzeug oder von Hand entnommen werden kann. Im oberen Bereich dienen die Vorrichtungen / Schablonenals hilfreiche Führungen.By virtue of the procedure according to the invention, a quantifiable amount of hardening viscous material, such as liquid concrete, can now be used and unnecessary use of concrete can be avoided. Due to the buoyancy of the plug in the moist curing material according to the Archimedes principle of buoyancy equal to the weight of the displaced Flüssigkeitssenge the dowel can be driven easily by means of a rod or light blows flush to the surface. As a result of the leadership of the pot-like mounting flange in the circular section of the ceiling and the intermediate viscous material, the bottom tube, analogous to the function of a self-aligning bearing, here with viscous compensating material, easily pendulum-like schwenkausrichtung and brought into the vertical. It is particularly advantageous if this impressions down and aligning in the circular section with a centering rod with a circular level bubble at the top and so the impressions and aligning takes place simultaneously .. The edge of the drilled ceiling acts as a fulcrum and the dowel remains due of the viscous material until its curing in the once set position. The buoyancy of the anchor with its cavity and its adhesion to the concrete are in such a relationship to the soft concrete that the depressed dowels always remains in the depressed position, but moves when aligning. With the use of the templates (56) and (57) the excavation in the lower area can be designed so that concrete surplus is avoided and at the same time the excavation can be removed with standard tools or by hand. At the top, the devices / templates serve as helpful guides.
Durch das erfindungsgemäße Verfahren und das Bodendübelsystem ist ein ausgerichtetes Einbringen von Bodendübeln bei geringstem Aufwand an mörtelartigem Material, angepasst an die verschiedensten Anforderungen - wie der Untergrundbeschaffenheit - mit einer effektiven, kostengünstigen Arbeitsweise und einer modularen Vorrichtung, dem Dübelsystem, in kompakter und bodenbündiger Bauweise möglich.The inventive method and the ground dowel system is an aligned introduction of ground dowels with the least amount of mortar-like material adapted to a variety of requirements - such as the surface texture - with an effective, cost-effective operation and a modular device, the anchor system, in a compact and flush construction ,
Ein besonderer Vorteil der Erfindung ist ihr ästhetisch ansprechender Eindruck, der durch die Verwendung von Vorlochschablonen und Aushubschablonen, welche eine Beschädigung des Bohrungsrandesder Decke vermeiden, zu ,Stande kommt. Der Topf des Dübels schließt in ansprechender Weise mit der Bohrung in der Decke ab, denn aufgrund der Schablonen wird eine Beschädigung der Decke durch Vorlochen oder weiteres Räumen vermieden.A particular advantage of the invention is its aesthetically pleasing appearance, which is achieved by the use of pre-hole templates and excavation templates which avoid damaging the bore edge of the ceiling. The pot of the dowel closes in an appealing manner with the hole in the ceiling, because of the templates damage to the ceiling by pre-puncture or further spaces is avoided.
Die Erfindung bezieht sich also auf ein Verfahren zur Verankerung von Bodendübeln für stabförmige Gegenstände (4), in Böden mit befestigter Oberfläche (Decke) (52) mittels eines Bodendübelsystems (1) mit einem Bodenrohr (2) zur Aufnahme eines Pfostenabschnitts, das einen topfartigen Befestigungsflansch (7) in Form eines in Richtung des Erdendes des Bodendübels geöffneten Topfes mit einem Boden (15) und einer vertikalen Ringwand (16), Schraubhülsen im Topfboden (15), Entlastungsöffnungen (17) trägt und ein geschlossenes Erdende besitzt, mit den Schritten: Herstellen eines definierten Kreisausschnitts in der Decke (52); Graben eines Schachts (51) im Boden (50) unter dem Kreisausschnitt der Decke (52) dessen Querschnitt dem Kreisausschnitt in der Decke (52) entspricht und dessen Länge ausreicht, dass das Bodenrohr im Schacht frei schwenkbar ist; wobei der Durchmesser des Kreisausschnitts in der Decke (52) um 1-10 %, bevorzugt 3- 6 % größer als der Durchmesser des topfartigen Befestigungsflansches (7) ist, damit der Dübel in im Schacht (51) um 10° bis 20° gegen die Bodenrohrachse schwenkbar ist;The invention thus relates to a method for anchoring ground dowels for rod-shaped objects (4), in floors with a fixed surface (ceiling) (52) by means of a ground dowel system (1) with a bottom tube (2) for receiving a post portion, the cup-like Mounting flange (7) in the form of a pot open in the direction of the ground end of the ground anchor with a bottom (15) and a vertical annular wall (16), screw sleeves in the bottom of the pot (15), discharge openings (17) and has a closed end, with the steps : Making a defined circular cutout in the ceiling (52); Digging a shaft (51) in the bottom (50) below the circular section of the ceiling (52) whose cross section corresponds to the circular cutout in the ceiling (52) and whose length is sufficient for the bottom tube in the shaft is free to pivot; wherein the diameter of the circular section in the ceiling (52) by 1-10%, preferably 3- 6% greater than the diameter of the cup-like mounting flange (7), so that the dowel in the shaft (51) by 10 ° to 20 ° against the bottom tube axis is pivotable;
Einbringen einer dem Schachtvolumen ohne Dübelvolumen vorbestimmten entsprechenden Menge viskosen aushärtenden Materials in den gegrabenen Schacht (51); Eindrücken des Bodendübels (1) in das aushärtende Material, so dass der topfartige Befestigungsflansch (7) innerhalb der Decke (52) zu liegen kommt, das aushärtende Material am geschlossenen Bodenrohr (2) im Schacht (51) bis zur Decke (52) in den topfartigen Flansch (7) hochgedrückt wird und den Schacht (51) sowie ggf. die Entlastungsöffnungen (26) füllt;
Ausrichten des Bodendübels (1) im aushärtenden Material durch Schwenken um die Mittelachse des Flansches (7) über einen Kontakt zwischen der Ringwand des Topfes (7) mit der Innenwand des Kreisausschnitts in der Decke (52) im noch weichen aushärtenden Material unter Nachfließen des viskosen Materials und Stabilisierung des Dübels der ausgerichteten Lage;
Aushärten lassen des Materials; und
Anschrauben einer Abdeckplatte (60) oder einer Spannring-/Spannplattenkombination (12, 8, 11) für Pfosten am Befestigungsflansch (7).Introducing into the excavated well (51) a quantity of viscous thermosetting material predetermined to the well volume without plug volume; Press the ground anchor (1) into the hardening material, leaving the pot-like Mounting flange (7) within the ceiling (52) comes to rest, the hardening material on the closed bottom tube (2) in the shaft (51) to the ceiling (52) in the cup-shaped flange (7) is pushed up and the shaft (51) and possibly filling the discharge openings (26);
Aligning the ground anchor (1) in the hardening material by pivoting about the central axis of the flange (7) via a contact between the annular wall of the pot (7) with the inner wall of the circular section in the ceiling (52) in the still soft curing material with subsequent flow of the viscous Material and stabilization of the anchor of the aligned layer;
Curing the material; and
Screwing on a cover plate (60) or a clamping ring / clamping plate combination (12, 8, 11) for posts on the mounting flange (7).
Durch das Vorsehen einer ausgewählten Schachtgeometrie kann der Dübel mit wenig aushärtendem Material vergossen werden, denn es wird kein Beton/Mörtelüberschuß notwendig. Der häufig als viskoses Material verwendete Beton/Mörtel ist kein umweltfreundliches Material und sollte daher so wenig wie nötig eingesetzt werden, was die Erfindung ermöglicht. Durch das Ausrichten des Dübels in Art eines Pendellagers, wobei der Kreisausschnitt in der Decke als Außen-Lager, der Rand des topfartigen Befestigungsflansches als Innenlager und das noch weiche viskose Material als Verbindungsglied dient, ist so eine unproblematische exakte Positionierung des Dübels möglich und das nachfließende viskose Material erhält diese und befestigt sie beim Aushärten.By providing a selected shaft geometry, the dowel can be cast with little hardening material, because it is no concrete / mortar excess necessary. The concrete / mortar often used as a viscous material is not an environmentally friendly material and should therefore be used as little as necessary, what the invention allows. By aligning the anchor in the manner of a self-aligning bearing, the circular section in the ceiling as an outer bearing, the edge of the pot-like mounting flange serves as a bottom bracket and the still soft viscous material as a link, so a problematic exact positioning of the anchor is possible and the nachfließende Viscous material receives this and attaches it during curing.
Das Ausrichten des Dübels kann in üblicher Weise mittels einer Wasserwaage oder einer Libelle an einem in die Pfostenöffnung eingesteckten Stab kontrolliert werden. Dabei wird der Dübel in Art eines Pendellagers gegen die Innenwand des Decken-Kreisausschnittes geschwenkt und so vertikal ausgerichtet. Der Dübel kann auch innerhalb der durch den Decken-Kreisausschnitt gebildeten Führung gedreht werden, falls rechteckige Pfähle mit einer Vorzugsrichtung befestigt werden sollen - bspw. bei Verkehrszeichen.The alignment of the anchor can be controlled in the usual way by means of a spirit level or a dragonfly on a rod inserted into the post opening. The dowel is pivoted in the manner of a self-aligning bearing against the inner wall of the ceiling circular cutout and so vertically aligned. The dowel can also be rotated within the guide formed by the ceiling circular cutout, if rectangular piles are to be fastened with a preferred direction - for example, in traffic signs.
Dadurch, dass mittels einer Bohrkrone oder einer Stanzeinrichtung ein kreisförmiger Ausschnitt definierter Größe in der Decke des befestigten Bodens hergestellt wird, der nur geringfügig größer als der Durchmesser des Dübelflansches ist, kann die Innenwand des kreisförmigen Ausschnitts beim Ausrichten des in einen unter dem kreisförmigen Ausschnitt gegrabenen Schachts eingebrachten Bodenrohrs als Drehpunkt wirken und ein Versinken des Flansches im feuchten aushärtbaren Material verhindern. Infolge dieser engen Führung des Dübelflansches sowie den Adhäsions- und Auftriebskräften entsteht ein Kräfte-Gleichgewicht, wonach der Dübel weder versinkt noch im viskosen Material aufsteigt. Indem nach Herstellung des Ausschnitts eine definierte Schachtgeometrie mittels eines Handbaggers, Stanzeinrichtung, Bohrkrone oder sonstiger Grabeinrichtung hergestellt wird, kann ohne Verwendung unnötig großer Mengen aushärtbaren Materials eine Befestigung des Bodenrohrs nach Ausrichtung erfolgen. Bisher war es problematisch, dass meist unnötig viel Beton in den ohne besondere geometrische Vorgabe ausgehobenen Hohlraum gegossen wurde - eine umweltschädliche Materialverschwendung, die auch zu Problemen beim Ausrichten des Dübels führte. Dadurch, dass der Dübel beim erfindungsgemäßen Verfahren aufgrund der definierten Schachtgeometrie und Geometrie des Deckenausschnitts nur begrenzte Bewegungsmöglichkeiten hat und gegen ein Auflager an der Innenwand des Kreisausschnittes in der Decke geschwenkt wird, ist seine Ausrichtung sowie seine Befestigung durch Aushärten des Materials leicht und materialsparend möglich.Characterized in that by means of a drill bit or a punching device, a circular cutout of defined size is made in the ceiling of the fixed floor, the is only slightly larger than the diameter of the dowel flange, the inner wall of the circular cutout can act as a fulcrum in aligning the bottom tube introduced into a well dug below the circular cutout and prevent sinking of the flange in the moist hardenable material. As a result of this tight guidance of the anchor flange and the adhesion and buoyancy forces creates a balance of forces, after which the dowel neither sinks nor rises in the viscous material. By producing a defined shaft geometry by means of a hand excavator, punching device, drill bit or other grave device after production of the cutout, attachment of the bottom tube to alignment can be carried out without using unnecessarily large quantities of curable material. Previously, it was problematic that mostly unnecessarily much concrete was poured into the excavated without special geometric specification cavity - an environmentally harmful waste of material, which also led to problems in aligning the anchor. Because the dowel in the method according to the invention due to the defined shaft geometry and geometry of the ceiling section has limited movement options and is pivoted against a support on the inner wall of the circular cut in the ceiling, its alignment and its attachment by curing the material is easy and save material possible.
Falls ein längeres Bodenrohr benötigt wird - bspw. wegen der Art des Untergrunds oder zwecks besserer Befestigung kann das Bodenrohr vor Einbringen in den Schacht durch mindestens ein Verlängerungsrohr mit einer Aufnahmeöffnung für das Bodenrohr-Erdende und einem Verlängerungsrohr-Erdende verlängert werden, wobei der Schacht dann entsprechend der Geometrie des verlängerten Bodenrohrs tiefer ausgehoben wird, wobei der Schacht (51) entsprechend länger als das verlängerte Bodenrohr (2, 20) ausgehoben wird.If a longer floor pipe is required - for example because of the type of substrate or for better fixing - the floor pipe may be extended prior to insertion into the hoistway by at least one extension pipe having a bottom pipe earth end receiving opening and an extension pipe earth end is dug deeper according to the geometry of the extended bottom tube, wherein the shaft (51) is dug longer correspondingly longer than the extended bottom tube (2, 20).
Bei einer Ausführungsform muss nur ein Grunddübel vorbestimmter Länge hergestellt werden, der modular durch aufsteckbare Verlängerungsrohre verlängert werden kann.In one embodiment, only a basic dowel of predetermined length needs to be made, which can be modularly extended by attachable extension tubes.
Vorteilhafterweise haben das Bodenrohr (2) und/oder die Verlängerungsrohr e (20) Rückhalteeinrichtungen, die das Verschieben, Verdrehen und Herausziehen des Bodendübels (1) gegen das weiche Material erschweren und bei ausgehärtetem Material verhindern. Es handelt sich dabei um strömungsgünstige Vorsprünge und/oder Vertiefungen, um die das aushärtbare Material ohne Blasen- und Taschen-bildung herum fließen kann und aushärtet. Diese Rückhalteeinrichtungen erschweren das Verschieben, Verdrehen und Herausziehen des Bodendübels (1) gegen das aushärtende Material und unterstützen die Aufrechterhaltung der ausgerichteten Position, bis das aushärtende Material/Beton fest ist.Advantageously, the bottom tube (2) and / or the extension tube e (20) retaining means which make it difficult to move, twisting and pulling the ground anchor (1) against the soft material and prevent hardened material. These are aerodynamic protrusions and / or depressions around which the curable material without bubble and pocket formation around can flow and harden. These restraints make it difficult to move, twist and pull the ground anchor (1) against the hardening material and help maintain the aligned position until the hardening material / concrete is strong.

Dazu findet Aufbringen einer Pfostenbefestigung mit: einem Spannring (11) für den Pfosten und einer auf den Spannring (11) gegen den Befestigungsflansch (7) aufschraubbaren Spannplatte (8) mit Pfostenöffnung und Spannschraubenbohrungen (22); Einbringen eines Pfostenendes durch den Spannring (11) und die Spannplatten-Pfostenöffnung (10) in die Bodenrohröffnung,
Anziehen der Spannschrauben (9) gegen die Schraubhülsen im Befestigungsflansch (7) unter Kompression des Spannrings (12) unter Kraftschluß mit dem Pfosten (30) statt.After setting in / pouring in the ground anchor, posts can be fixed in the anchor. For this purpose, applying a post mounting with: a clamping ring (11) for the post and on the clamping ring (11) against the mounting flange (7) unscrewed clamping plate (8) with post opening and clamping screw holes (22); Inserting a post end through the clamping ring (11) and the clamping plate post opening (10) in the bottom tube opening,
Tightening the clamping screws (9) against the screw sleeves in the mounting flange (7) under compression of the clamping ring (12) under adhesion to the post (30) instead.
Diese Spannvorrichtung ermöglicht leichten Austausch der Pfosten und ist gegenüber Auffahrunfällen robust - d.h. es wird nur die Spannvorrichtung deformiert - der Dübel bleibt unverletzt.This tensioner allows easy replacement of the posts and is robust to rear-end collisions - i. only the clamping device is deformed - the anchor remains unharmed.
Ggf. kann eine Abdeckplatte mit Schrauböffnungen (24) auf den Flansch (7) unter Bedeckung der Pfostenöffnung aufgeschraubt werden, wenn z.Zt. kein Pfosten im Dübel aufgenommen ist.Possibly. a cover plate with screw holes (24) can be screwed onto the flange (7) while covering the post opening, if presently. no post is included in the dowel.

Die Vorrichtung wird daher hergestellt durch:
- A: das exakte Aufbohren der Decke, deren Ausschachtung und Begrenzung nach unten, dadurch entsteht
- Ein Außengehäuse mit Boden, wobei die Decke des Flächenabschnitts mit Befestigung, bspw. eine Straße, sowie das Erdreich Bestandteil der Vorrichtung wird.
- B: durch den der Öffnung in der Decke entsprechenden Befestigungsflansch wird eine ausrichtbare Funktions-Oberfläche mit einem Überdruckventil für das aushärtbare Material und die Pfostenaufnahme geschaffen, somit:
- ein pendelausrichtbarer Dübelkörper
- C:
ein auf Plusminus 10% vorherbestimmbares Volumen an einzusetzendem viskosen aushärtendem Material, das in vorteilhafter Weise vorbereitet werden kann, bspw. in einem dafür- skalierten Meßbehälter für das aushärtende Material. So kann die Ressource "aushärtbares Material, wie Beton" minimisiert werden.
- A: the exact boring of the ceiling, whose excavation and limitation down, thereby arises
- An outer housing with floor, wherein the ceiling of the surface portion with attachment, eg. A road, and the soil is part of the device.
- B: the mounting flange corresponding to the opening in the ceiling creates an alignable functional surface with an overpressure valve for the hardenable material and the post support, thus:
- a pendulum alignable dowel body
- C: a predictable to plus minus 10% volume of viscous curing material to be used, which can be prepared in an advantageous manner, for example, in one for
- scaled measuring container for the hardening material. Thus, the resource "hardenable material, such as concrete" can be minimized.
Es handelt sich im weiteren Sinne um ein "Integriertes Verankerungssystem und Verfahren zu seiner Herstellung".It is in the broader sense an "integrated anchoring system and method for its production".
Ein besonderer Vorteil der Erfindung besteht darin, dass nun das Einbringen der Pfosten wiederholbar und automatisierbar möglich ist. Somit können normierbare Bedingungen der Pfostenbefestigung geschaffen werden, wie sie bspw. für am Straßenverkehr teilnehmende Pfosten (z. B. Verkehrszeichen) erwünscht sind oder aber für einheitliche Gestaltung einer Stadtmöblierung.A particular advantage of the invention is that now the introduction of the posts is repeatable and automatable possible. Thus, normative conditions of the post attachment can be created, as they are, for example, desired for participating in the road posts (eg traffic signs) or for uniform design of street furniture.
Es ist günstig, wenn das Bodenrohr-Erdabschlußende integral mit dem Rohr (2) ist und eine strömungsgünstige Verjüngung aufweist, die durch Umformen zu einer runden geschlossenen ENde oder umgebogene, ausgeschnittene ungeformte Bodenrohrabschnitte geschlossen ist oder durch eine separate, am Erdende befestigte strömungsgünstig geformte Kappe (40) gebildet ist.It is advantageous if the bottom tube earth termination end is integral with the tube (2) and has a streamlined taper which is closed by forming into a round closed end or bent, cut unshaped bottom tube sections, or by a separate, end-capped, streamlined cap (40) is formed.
Durch die strömungsgünstige Form kann das Entstehen von Hohlräumen und Blasen im ausgehärteten Material, was zu Festigkeitsverlusten führt, vermieden werden.Due to the streamlined shape, the formation of voids and bubbles in the cured material, resulting in strength losses can be avoided.
Zur verstärkten Befestigung des Bodendübelsystems im Untergrund können das mindestens eine Bodenrohr (2) und/oder das Verlängerungsrohr (20) strömungsgünstige Verankerungserhebungen aufweisen.For reinforced attachment of the ground dowel system in the ground, the at least one bottom pipe (2) and / or the extension pipe (20) can have flow-favorable anchoring elevations.
Durch das Bodendübelsystem kann eine ausgerichtete, reversible Befestigung von Pfosten unter umweltfreundlich geringem Einsatz an aushärtbarem Material erzielt werden, wobei der Dübel dann, wenn er keinen Pfosten trägt, in effektiver und ansprechender Weise durch eine aufgeschraubte Abdeckplatte geschützt wird und im Bedarfsfalle leicht freigelegt werden kann.Through the floor dowel system, an aligned, reversible attachment of posts under environmentally friendly use of low-curable material can be achieved, the dowel when he carries no post is protected in an effective and attractive way by a screwed cover plate and can be easily exposed if necessary ,
Der Grundgedanke besteht also darin, daß Bodendübel unter möglichst geringer Belastung der Umwelt durch ein wiederholbares Vorgehen ausgerichtet eingebracht werden und in einfacher Weise an wechselnde, von ihnen aufzunehmende Pfosten und ähnliche stabförmige Gegenstände bzw. aufzunehmende Lasten anpassbar sind, ohne aufwändige Lagerhaltung zu betreiben.The basic idea is therefore that ground anchors are placed under the least possible burden on the environment by a repeatable approach and easily adaptable to changing, to be absorbed by them post and similar rod-shaped objects or loads to be absorbed without consuming to store.
Da nun Bodenrohre eines Bodendübels mit Verlängerungsrohren unterschiedlicher Länge und ggf. wechselbaren Endstücken versehen werden können, ist es möglich, ein Bodendübelsystem zu schaffen, das leicht an die örtlichen Gegebenheiten und Bodenverhältnisse angepaßt werden kann.Now that floor pipes of a ground anchor can be provided with extension pipes of different lengths and possibly interchangeable tails, it is possible to provide a ground dowel system that can be easily adapted to local conditions and soil conditions.
Desweiteren ist es möglich nicht nur das Verlängerungsrohr am Erdende mit einerm überstehenden Verankerungswulst zur verbesserten Verankerung zu versehen. Auch der Schacht 51 kann während seinem Aushub konisch nach unten erweitert werden, sodaß auch das ausgehärtete viskose Material selbst einen zweiten Verankerungswulst oder Konus bildet und das Gesamtsystem eine hohe Ausreißfestigkeit erhält.Furthermore, it is possible not only to provide the extension tube at the ground end with a protruding anchoring bead for improved anchoring. Also, the
Aufgrund der Tatsache, dass nun vordefinierte Öffnungen in der Decke einer befestigten Oberfläche hergestellt werden, durch die ein Betonierschacht vorbestimmter Größe ausgehoben wird, kann ein Überschuß an Beton vermieden werden und der damit verbundene Aufwand reduziert werden.Due to the fact that now predefined openings are made in the ceiling of a fixed surface through which a concreting pit of predetermined size is excavated, an excess of concrete can be avoided and the associated expense can be reduced.
Da bspw. in noch viskosen feuchten Beton der Bodendübel - abgestützt durch die Kreisausschnittswand in der befestigten Decke - leicht senkrecht ausgerichtet werden kann, ist in einfacher Weise eine exakte Positionierung der Pfostenöffnung und damit des einzubringenden Pfosten gegeben.For example, in still viscous wet concrete of the ground anchors - supported by the circular cutout wall in the paved ceiling - are easily aligned vertically can, is given in a simple manner an exact positioning of the post opening and thus the post to be introduced.
Dadurch, dass an die Bodenrohre verschiedene Endstücke angefügt werden können, ist es möglich, die Dübel, falls notwendig, zu verlängern und auch ihre Form entsprechend den Anforderungen (Endspitze oder abgerundete Spitze) auszugestalten. So können, falls notwendig, mehr Rückhalteeinrichtungen für besseren Halt im Beton vorgesehen werden. Es können auch weiche Kappen als Abschlußstücke eingesetzt werden, falls eine Beschädigung empfindlicher Einrichtungen im Untergrund vermieden werden soll - aber es können aber auch Einschlagspitzen, die sich in harten Untergrund bohren, angeschlossen werden. Erfindungsgemäß ist es auch möglich, die Pfahlöffnung im Dübel reversibel mittels der Abdeckplatte zu verschließen, um Verschmutzung und Beschädigung des Flansches und der Pfahlöffnung zu vermeiden.The fact that different end pieces can be attached to the floor pipes, it is possible to extend the dowels, if necessary, and also to design their shape according to the requirements (end tip or rounded tip). Thus, if necessary, more retaining devices can be provided for better grip in the concrete. It is also soft caps can be used as terminators, if damage to sensitive equipment in the underground should be avoided - but it can also be impact tips that drill in hard ground, are connected. According to the invention it is also possible to reversibly close the pile opening in the dowel by means of the cover plate in order to avoid contamination and damage to the flange and the pile opening.
Mögliche Materialien für das System sind korrosionsfeste, elastische Materialien, u.a. Stahl, Guß, Sintermetall, Aluminium, Messing sowie hochfeste Kunststoffe.Possible materials for the system are corrosion-resistant, elastic materials, i.a. Steel, cast iron, sintered metal, aluminum, brass and high-strength plastics.
Dadurch, dass erfindungsgemäß nunmehr aufgrund der vorbestimmten Schachtmaße nur eine definierte Menge aushärtbaren Materials benötigt wird, kann der Schacht sowohl einfach hergestellt werden, als auch der einbetonierte Dübel ggf. auch leicht wieder mitsamt dem Beton aus dem Boden entfernt werden - bspw. mittels einer entsprechenden Bohrkrone oder Topfmeißels. Ein Ausrichten des Bodendübels gegen die Innenwand des Decken-Kreisausschnitts ist im feuchten Beton mühelos und mit geringem Kraftaufwand möglich - sowohl hinsichtlich der Höhe, als auch der Richtung und der Orientierung des Dübels, falls Rechteckprofile eingesetzt werden sollen.Due to the fact that according to the invention now only a defined amount of curable material is required due to the predetermined shaft dimensions, the shaft can be easily produced, as well as the cast-in anchors may also be easily removed together with the concrete from the ground - for example by means of a corresponding Drill bit or cup chisel. An alignment of the ground dowel against the inner wall of the ceiling circular cut is possible in wet concrete effortlessly and with little effort - both in terms of height, as well as the direction and orientation of the anchor, if rectangular profiles are to be used.
