Description

Die Erfindung betrifft einen Anschlaghalter mit einem Anschlag für eine Wandschalung zum Errichten einer Betonwand auf einem betonierten Untergrund, wobei der Anschlaghalter über ein Feststellmittel an einem aufragenden Armierungsanschlusseisen festlegbar ist.The invention relates to a stop holder with a stop for a wall formwork for erecting a concrete wall on a concrete surface, using the stop bracket via a locking device on a towering reinforcement connection iron is definable.

Aus der DE-A-4439959 ist eine Klemmvorrichtung zur Festlegung eines als Querstab mit Endanschlägen ausgebildeten Distanzhalters bekannt. Beim Errichten einer zweihäuptigen Wandschalung dient der Distanzhalter zur Einstellung eines definierten Abstandes zwischen zwei gegen die Endanschläge verspannte Schalwände. Die vorbekannte Klemmvorrichtung besteht aus einem U-förmigen Profilstück, an dessen Stirnseite zwei diametral gegenüberliegende Ausnehmungen zum Einsetzen des Distanzhalters vorgesehen sind. Zur Montage des Distanzhalters wird das Profilstück an das Anschlusseisen angelegt und der Distanzhalter in die Ausnehmungen eingesetzt. Nach dem Ausrichten des Distanzhalters auf eine Richtschnur wird zur Fixierung zwischen Distanzhalter und Anschlusseisen ein Keil eingetrieben. Die Handhabung der aus den drei Teilen Profilstück, Klemmkeil und Distanzhalter bestehenden Anordnung erweist sich jedoch im praktischen Einsatz als umständlich. Zudem erfordert das präzise Ausrichten des Distanzhalters wegen der Dreiteiligkeit der Anordnung ein hohes Mass an Geschicklichkeit. Als nachteilig erweist sich auch die Verwendung des Profilstücks bei unterschiedlich dicken Anschlusseisen. Die Ausnehmungen an jeder Stirnseite sind in unterschiedlicher Distanz zur Profilrückwand angeordnet. Vor dem Anlegen des Profilstücks an das Anschlusseisen muss jeweils überlegt werden, welche der beiden Stirnseiten bei vorgegebener Dicke des Anschlusseisens zum Einsetzen des Distanzhalters verwendet werden muss, da der Keil bei falscher Wahl praktisch versenkt wird und nur umständlich wieder entfernt werden kann. Ein weiterer Nachteil ergibt sich auch bei Falschzentrierung des Distanzhalters, da das Lösen eines einmal eingeschlagenen Keils praktisch nicht mehr möglich ist. Hinzu kommt, dass herkömmliche Distanzhalter die beiden Schalwände einer zweihäuptigen Wandschalung miteinander verbinden, d.h. die Distanzhalter sind von Wand zu Wand durchgehend. Dies hat zur Folge, dass eine auf diese Weise erstellte Betonwand nicht wasserdicht ist, was den Einsatz der Distanzhalter bei gewissen Anwendungen wie Wänden von Reservoirs einschränkt.From DE-A-4439959 is a clamping device for fixing a spacer designed as a crossbar with end stops known. When building a two-sided The wall form is used to set a spacer defined distance between two against the end stops tensioned formwork walls. The known clamping device consists of a U-shaped profile piece on the front side two diametrically opposite recesses for Insertion of the spacer are provided. For assembly the spacer is the profile piece to the connecting iron and the spacer in the recesses used. After aligning the spacer on one The guideline is used to fix between the spacer and Connection iron driven a wedge. The handling of the the three parts profile piece, clamping wedge and spacer existing arrangement, however, proves to be practical Use as cumbersome. This also requires precise alignment of the spacer because of the three-part arrangement a high level of skill. As a disadvantage the use of the profile piece also proves to be different thick connecting iron. The recesses on everyone The end face is at different distances from the profile rear wall arranged. Before placing the profile piece on the Connection iron must be considered which of the two End faces with a given thickness of the connecting iron must be used to insert the spacer because if the wrong choice is made, the wedge is practically sunk and only cumbersome to remove. Another disadvantage results even if the spacer is incorrectly centered, because loosening a wedge once practically is no longer possible. Add to that conventional Spacers the two formwork walls of a two-sided Connect the wall formwork together, i.e. the spacers are continuous from wall to wall. As a result, a concrete wall created in this way is not waterproof is what the use of spacers in certain applications like walls of reservoirs.

Angesichts dieser Gegebenheiten hat sich der Erfinder die Aufgabe gestellt, einen Anschlaghalter der eingangs genannten Art zu schaffen, der bei einfacher Handhabung ein rasches Setzen mit hoher Richtgenauigkeit ermöglicht. Zudem soll der Anschlaghalter auch zum Erstellen wasserdichter Betonmauern eingesetzt werden können.In view of these circumstances, the inventor has the Task given a stop holder of the aforementioned Art to create a quick with easy handling Allows setting with high accuracy. In addition, the Stop bracket also for creating waterproof concrete walls can be used.

Zur erfindungsgemässen Lösung der Aufgabe führt, dass der Anschlaghalter eine Aufnahmeöffnung für das Anschlusseisen aufweist und vor seiner Fixierung um die Achse des Anschlusseisens drehbar ist, wobei der Anschlag als gekrümmte Anschlagfläche mit zur Achse des Anschlusseisens sich stetig veränderndem Abstand ausgebildet ist.To achieve the object according to the invention, that the stop holder has a receiving opening for the connecting iron has and before its fixation around the axis of the connecting iron is rotatable, the stop being curved Stop surface with to the axis of the connecting iron constantly changing distance is formed.

Im Gegensatz zu herkömmlichen Distanzhaltern mit in einem Halterungsteil verschiebbar geführtem Querstab mit Endanschlägen ist beim erfindungsgemässen Anschlaghalter der Anschlag integriert, d.h. der am Anschlusseisen festzulegende Teil ist unmittelbar mit einem Anschlag versehen. Damit ergibt sich zusammen mit dem Feststellmittel eine zweiteilige Anordnung, die durch einfaches Drehen des Anschlaghalters eine präzise Ausrichtung des Anschlages auf die Richtschnur ermöglicht.In contrast to conventional spacers with in one Bracket slidably guided cross bar with end stops is the stop holder according to the invention Integrated stop, i.e. the one to be determined on the connecting iron Part is immediately provided with a stop. In order to results in a two-part together with the locking means Arrangement by simply turning the stop holder a precise alignment of the stop on the Guideline enables.

Der erfindungsgemässe Anschlaghalter ist nicht mehr von Wand zu Wand durchgehend, sondern bildet jeweils einen Einzelanschlag zur angrenzenden Schalwand. Demzufolge kann entlang des Anschlaghalters eindringendes Wasser im Gegensatz zu herkömmlichen Distanzhaltern nur noch geringfügig in die Betonmauer eindringen und diese insbesondere nicht mehr vollständig durchdringen. Demzufolge ist der erfindungsgemässe Anschlaghalter auch zum Bau von wasserdichten Betonwänden geeignet.The stop holder according to the invention is no longer off the wall continuous to the wall, but forms a single stop to the adjacent formwork wall. As a result, along penetrating water as opposed to conventional spacers only slightly into the Penetrate concrete wall and especially not anymore penetrate completely. Accordingly, the is according to the invention Stop bracket also for the construction of waterproof concrete walls suitable.

Dank seinem nur einseitigen Anschlag kann der erfindungsgemässe Anschlaghalter problemlos auch dort verwendet werden, wo zur Verhinderung des Eindringens von Sickerwasser am Boden der zu erstellenden Wand ein umlaufendes Gummiband eingesetzt wird.Thanks to its one-sided stop, the inventive Stop brackets can also be used there without any problems, where to prevent the infiltration of leachate on the ground a circumferential rubber band is used for the wall to be created becomes.

Bei einer bevorzugten Ausführungsform des erfindungsgemässen Anschlaghalters ist die Krümmung der Anschlagfläche kreis- oder ellipsenförmig ausgebildet. Mit der Ellipsenform ergibt sich eine grössere Variation der Einstellmöglichkeiten für die Anschlagdistanz. Bei einer zylindrischen Anschlagfläche liegt die Achse des Anschlusseisens exzentrisch zur Zylinderachse. Bei ellipsenförmiger Anschlagfläche kann sie sowohl in einer Ellipsenachse als auch exzentrisch dazu liegen.In a preferred embodiment of the inventive Stop bracket is the curvature of the stop surface circular or elliptical. With the ellipse shape there is a greater variation in the setting options for the stroke distance. With a cylindrical The axis of the connecting iron is eccentric to the cylinder axis. With an elliptical stop surface it can be both in an elliptical axis and eccentric to be.

Als Feststellmittel zur Fixierung des Anschlaghalters an einem Anschlusseisen können allgemein bekannte Mittel eingesetzt werden, so z.B. eine den Anschlaghalter gegen das Anschlusseisen verspannende Stellschraube.As a locking device for fixing the stop bracket a connecting iron, generally known means can be used become, e.g. one the stop holder against that Set screw tightening connecting iron.

Bei einer besonders bevorzugten Ausführungsform ist die Aufnahmeöffnung für das Anschlusseisen als hinterschnittene Nut zur Aufnahme eines zwischen Anschlusseisen und Gegenflächen der Nut eintreibbaren Keilelementes ausgebildet.In a particularly preferred embodiment, the receiving opening is for the connecting iron as undercut Groove for receiving one between connecting iron and counter surfaces the groove-driven wedge element is formed.

Der Anschlaghalter kann beispielsweise einstückig aus Metall oder aus einem ggf. faserverstärkten Kunststoff gefertigt sein. Eine weitere Möglichkeit wird darin gesehen, dass der Anschlaghalter aus einem die Anschlagfläche aufweisenden Anschlagteil und einem mit diesem starr verbundenen, die hinterschnittene Nut aufweisenden Befestigungsteil besteht.The stop holder can, for example, be made in one piece from metal or made of a possibly fiber-reinforced plastic his. Another possibility is seen in that the stop holder from one having the stop surface Stop part and a rigidly connected to this, the undercut groove having fastening part.

Bei der besonders bevorzugten Ausführungsform ist der Befestigungsteil als Profilstück mit im wesentlichen U-förmigem Querschnitt ausgebildet, wobei die freien Enden der U-Schenkel unter Bildung der Gegenflächen nach innen abgewinkelt sind. Zur vereinfachten Zentrierung des Profilstücks am Anschlusseisen können die U-Schenkel eine oder auch mehrere Knickstellen aufweisen.In the particularly preferred embodiment, the fastening part as a profile piece with a substantially U-shaped Cross-section formed, the free ends of the U-legs angled inwards to form the counter surfaces are. For simplified centering of the profile piece on the connecting iron can the U-legs one or more Have kinks.

Bei einer weiter bevorzugten Ausführungsform sind die freien Enden der U-Schenkel derart abgewinkelt, dass sie mit entsprechenden Längsnuten im Keilelement in Eingriff bringbar sind. Dadurch erhöht sich die Stabilität der gesamten Anordnung.In a further preferred embodiment, the free ones Angled ends of the U-legs in such a way that they correspond with the corresponding Longitudinal grooves in the key element can be engaged are. This increases the stability of the entire arrangement.

Das Profilstück kann beispielsweise aus Metall gefertigt und in ein Anschlagteil aus Kunststoff eingesetzt sein. Es ist auch denkbar, dass das Anschlagteil aus Metall besteht und mit Kunststoff ummantelt bzw. beschichtet ist.The profile piece can be made of metal, for example be inserted into a plastic stop part. It is also conceivable that the stop part is made of metal and is coated or coated with plastic.

Zur Erhöhung der Stabilität der Anordnung kann das Keilelement in eingesetzter Lage über einen abgewinkelten Kopfteil am Anschlusseisen anliegen. Weiter kann der Kopfteil eine Quernut zur Aufnahme eines herkömmlichen Distanzhalters aufweisen. Bei einer anderen möglichen Ausgestaltung des Keilelementes kann dieses direkt als Halterungsteil für einen Distanzhalter ausgebildet sein. The wedge element can be used to increase the stability of the arrangement in the inserted position over an angled headboard rest on the connecting iron. The head part can also be a Cross groove to accommodate a conventional spacer exhibit. In another possible embodiment of the Wedge element can this directly as a mounting part for a spacer may be formed.

Von einem Betonboden 10 ragt gemäss Fig. 1 ein Armierungsanschlusseisen 12 mit einem an diesem festgelegten Anschlaghalter 14 auf. Der Anschlaghalter 14 besteht aus einem zylinderförmigen Anschlagteil 16 mit der Zylindermantelfläche als Anschlagfläche 18 sowie einem mit dem Anschlagteil 16 starr verbundenen Profilstück 20 als Befestigungsteil zur Festlegung des Anschlaghalters 14 am Anschlusseisen 12. Die Achse z des Anschlusseisens 12 liegt gegenüber der Achse t des zylinderförmigen Anschlagteils 16 exzentrisch. Demzufolge verändert sich der Abstand r von der Achse z zur Anschlagfläche 18 kontinuierlich. Selbstverständlich können, in Abweichung zur dargestellten Ausführungsform, das Anschlagteil 16 und das Profilstück 20 in bezug auf die Achse z des Anschlusseisens 12 gleich hoch ausgebildet sein.According to FIG. 1, a reinforcing connecting iron protrudes from a concrete floor 10 12 with a stop bracket attached to it 14 on. The stop holder 14 consists of a cylindrical one Stop part 16 with the cylindrical surface as a stop surface 18 and one with the stop part 16 rigidly connected profile piece 20 as a fastening part for Fixing the stop bracket 14 on the connecting iron 12. Die Axis z of the connecting iron 12 lies opposite the axis t of the cylindrical stop part 16 eccentrically. As a result, the distance r changes from the axis z to the stop surface 18 continuous. Of course, in deviation from the illustrated embodiment, the stop part 16 and the profile piece 20 with respect to the axis z of the connecting iron 12 be of the same height.

Das Profilstück 20 weist gemäss Fig. 2 einen im wesentlichen U-förmigen Querschnitt auf. Die Schenkelteile 22 gehen bei einer schwachen Knickstelle 24 in untere Schenkelteile 26 über und bilden im Profilgrund 28 einen verhältnismässig engen Radius. Durch die besondere Querschnittsausbildung des Profilstücks 20 erfolgt eine selbsttätige Zentrierung beim Anlegen des Anschlaghalters an das Anschlusseisen. Die freien Enden der Schenkelteile 22 sind unter Bildung von Gegenflächen 30 nach innen abgewinkelt.According to FIG. 2, the profile piece 20 essentially has one U-shaped cross section. The leg parts 22 go along a weak kink 24 in lower leg parts 26 about and form a proportion in the base 28 narrow radius. Due to the special cross-sectional training the profile piece 20 is automatically centered when placing the stop holder on the connecting iron. The free ends of the leg parts 22 are forming counter surfaces 30 angled inwards.

Das Profilstück 20 hat die Gestalt einer hinterschnittenen Nut 32 mit einer Aufnahmeöffnung 34 für das Anschlusseisen 12. In die hinterschnittene Nut 32 ist ein Keil 36 eingesetzt, der einerseits dem Armierungseisen 12 und andererseits dem Profilstück 20 über dessen Gegenflächen 30 anliegt.The profile piece 20 has the shape of an undercut Groove 32 with a receiving opening 34 for the connecting iron 12. A wedge 36 is inserted into the undercut groove 32, on the one hand the reinforcing iron 12 and on the other hand the profile piece 20 rests on its counter surfaces 30.

Der Keil 36 weist einen eine Schlagfläche 40 für einen Hammer bildenden Kopfteil 38 auf, der abgewinkelt ist und über eine Anlagefläche 44 dem Anschlusseisen 12 anliegt. Durch diesen vom Profilstück 20 entfernten zweiten Auflagepunkt ergibt sich eine erhöhte Stabilität der Verbindung. Im Kopfteil 38 des Keils 36 ist eine Quernut 42 für den zusätzlichen Einsatz eines herkömmlichen Distanzhalters vorgesehen.The wedge 36 has a striking surface 40 for a hammer forming head part 38, which is angled and over a Contact surface 44 abuts the connecting iron 12. Through this results from the profile piece 20 second support point increased stability of the connection. In the head part 38 the key 36 is a transverse groove 42 for additional use a conventional spacer provided.

Das Richten des Anschlaghalters 14 auf eine Richtschnur 46 ergibt sich ohne weiteres aus der Betrachtung von Fig. 4. Nach dem Anlegen des Anschlaghalters 14 an ein Anschlusseisen 12 wird der Keil 36 locker von oben in das Profilstück 20 zwischen Anschlusseisen 12 und Gegenflächen 30 eingesetzt. Dabei bleibt die freie Drehbarkeit um die Achse z des Anschlusseisens 12 vorerst erhalten. Der Anschlaghalter 14 wird sodann bis zur Berührung mit der Richtschnur 46 gedreht und in seiner endgültigen Lage durch Eintreiben des Keils 36 fixiert. Aus den drei beispielhaften Stellungen des Anschlaghalters 14 ist die Bedeutung der gegenüber der Achse t des Anschlagteils 16 exzentrisch liegenden Achse z des Anschlusseisens 12 klar ersichtlich. Die in drei verschiedenen Abständen angeordnete Richtschnur 46a,b,c berührt die Anschlagfläche 18 jeweils in einem Punkt 48a,b,c. Durch Drehen des Anschlaghalters 14 verändert sich der Abstand ra'b'c von der Achse z des Anschlusseisens 12 zum jeweiligen Anschlagpunkt 48a,b,c entsprechend.The direction of the stop holder 14 on a guide line 46 is readily apparent from the consideration of FIG. The free rotatability about the axis z of the connecting iron 12 is maintained for the time being. The stop holder 14 is then rotated until it touches the alignment line 46 and is fixed in its final position by driving in the wedge 36. The meaning of the axis z of the connecting iron 12 which is eccentric with respect to the axis t of the stop part 16 is clearly evident from the three exemplary positions of the stop holder 14. The alignment line 46a, b, c arranged at three different distances touches the stop surface 18 at a point 48a, b, c. By turning the stop holder 14, the distance r a'b'c from the axis z of the connecting iron 12 to the respective stop point 48a, b, c changes accordingly.

Die Fig. 5 bis 8 zeigen weitere Einsatzmöglichkeiten des Anschlaghalters 14.5 to 8 show further possible uses of the stop holder 14th

Gemäss Fig. 5 und 6 ist das Keilelement als Halterungsteil 50 für einen herkömmlichen Distanzhalter 52 mit Querstab 53 sowie Endanschlägen 54 aus Kunststoff ausgebildet. Das Halterungsteil 50 ist mit einem U-förmigen Blechband 56 aus Federstahl ausgestattet. Der in gegenüberliegenden Durchführungen 58 im Blechband 56 geführte Querstab 53 lässt sich durch Zusammendrücken des Blechbandes 56 frei verschieben und auf eine Richtschnur ausrichten. Durch die Vorspannung des Blechbandes 56 bleibt der Distanzhalter 52 in jeder Verschiebungslage selbsttätig fixiert. 5 and 6, the wedge element is a holding part 50 for a conventional spacer 52 with cross bar 53 and end stops 54 made of plastic. The bracket part 50 is with a U-shaped sheet metal strip 56 made of spring steel fitted. The one in opposite bushings 58 cross bar 53 guided in the sheet metal strip 56 can be move freely by compressing the metal strip 56 and align it with a guideline. By the preload the sheet metal strip 56, the spacer 52 remains in any displacement position fixed automatically.

Fig. 7 und 8 zeigen eine weitere Möglichkeit zum Festlegen eines Distanzhalters 52. Der Querstab 53 des Distanzhalters 52 wird in die Quernut 42 des in Fig. 1 gezeigten Keils 36 klemmend eingesetzt und beim Eintreiben des Keils 36 in das Profilstück 20 am Anschlusseisen 12 fixiert. Hierbei bildet der Querstab 53 an Stelle des Kopfteils 38 den zweiten Auflagepunkt des Keils 36 am Anschlusseisen 12.7 and 8 show another way of setting a spacer 52. The cross bar 53 of the spacer 52 is in the transverse groove 42 of the key 36 shown in FIG. 1 used clamping and when driving the wedge 36 into it Profile piece 20 fixed to the connecting iron 12.
