Description

Die vorliegende Erfindung betrifft einen Abstandhalter für Schalungen gemäss Oberbegriff des Patentanspruches 1.The present invention relates to a spacer for Formwork according to the preamble of claim 1.

Bei der Erstellung von Betonwänden werden bekanntlich Abstandhalter zwischen den beidseitigen Schalungen angeordnet und die Schalungen mittels die Abstandhalter durchsetzende Gewindespindeln zusammengehalten. Nach der Erstellung der Betonwand werden die Schalungen entfernt und die Gewindestangen, die die Abstandhalter durchsetzen, herausgezogen. Die so verbleibenden Durchgangslöcher müssen nachträglich verschlossen werden.As is well known, spacers are used when creating concrete walls arranged between the formwork on both sides and the Formwork using threaded spindles passing through the spacers held together. After creating the concrete wall the formwork is removed and the threaded rods that the Push through spacer, pulled out. The remaining ones Through holes must be closed later.

Es sind auch Systeme bekannt, die mit in der Betonwand verbleibenden Schraubbolzen ausgestattet sind und endseitige Auflagekonen aufweisen. Solche, hier nicht interessierende Systeme, sind beispielsweise aus den EP-A-0'288'583 und EP-A-0'346'466 bekannt.Systems are also known which remain in the concrete wall Bolts are equipped and end Have support cones. Such, not of interest here Systems are, for example, from EP-A-0'288'583 and EP-A-0'346'466 known.

Die hier interessierenden Abstandhalter für Schalungen sind solche, die ein die zu erstellende Betonwand durchsetzendes Distanzrohr aufweisen, welches in der erstellten Betonwand verbleibt. Ein solcher Abstandhalter für Schalungen mit einem Distanzrohr ist beispielsweise aus der DE-A-34 33 575 bekannt. Der hier dargestellte Abstandhalter besteht lediglich aus einem als Distanzrohr dienenden Hüllrohr, in dem ein Kunststoffzapfen mit einem Kern aus vorzugsweise faserverstärktem Zement eingeschlagen wird.The spacers for formwork that are of interest here are those that penetrate the concrete wall to be created Have spacer tube, which in the created concrete wall remains. Such a spacer for formwork with one Spacer tube is known for example from DE-A-34 33 575. The spacer shown here only consists of a cladding tube serving as a spacer tube, in which a plastic pin with a core of preferably fiber-reinforced Cement is hammered in.

Ein den Oberbegriff des Anspruchs 1 bildender Abstandhalter für Schalungen ist aus der AT-A-371 877 bekannt. Es handelt sich hierbei um einen Abstandhalter für Schalungen mit einer Abdeckung, umfassend ein in der Betonwand verbleibendes Distanzrohr mit mindestens an der äusseren Sichtseite einer Betonwand an der Schalung zum Anliegen kommenden Auflagekonus und einer Abdeckung zum Verschliessen der Oeffnung in der Betonwand. Der Auflagekonus und das Distanzrohr sind zusammensteckbar ausgestaltet. Hierbei umgreift der Auflagekonus das Distanzrohr endseitig. Der Auflagekonus ist vorzugsweise aus Kunststoff gefertigt und weist zur Verankerung in der Wand nach aussen gerichtete radiale und axiale Rippen auf. Der Auflagekonus ist hohl und weist eine definierte innere Oeffnung auf, die dem Aussenmass einer nachträglich einsetzbaren Abdeckung entspricht.A spacer forming the preamble of claim 1 for formwork is known from AT-A-371 877. It is a spacer for formwork with a cover comprising one remaining in the concrete wall Spacer tube with at least one on the outer visible side Concrete wall on the formwork that comes to rest on the support cone and a cover for closing the opening in the Concrete wall. The support cone and the spacer tube can be plugged together designed. The support cone encompasses this Spacer tube at the end. The support cone is preferably off Made of plastic and has anchoring in the wall outward radial and axial ribs. The The support cone is hollow and has a defined inner opening that can be used retrospectively Cover corresponds.

Für viele Anwendungen, die nicht im Sichtbereich sind oder bei denen die Betonwand nachträglich mit einem Verputz abgedeckt wird, eignet sich diese Lösung. Für reine Sichtbetonwände vermag jedoch diese Lösung aus verschiedenen Gründen, insbesondere aus ästhetischen Gründen, nicht zu überzeugen. Sowohl der Auflagekonus, wie auch die Abdeckung in Form eines in den Konus einpressbaren Zapfens, sind aus Kunststoff und setzen sich optisch gegenüber der Sichtbetonwand stark ab. Auch als dekoratives Element mit entsprechender Farbgebung ist dieser Abstandhalter wenig geeignet, da sich bei einer Sichtbetonwand der Kunststoff unter Einfluss der UV-Strahlung verfärbt und trübe wird.For many applications that are not in the field of vision or for which the concrete wall subsequently covered with plaster this solution is suitable. For pure exposed concrete walls however, this solution is capable of several reasons, in particular for aesthetic reasons, not to convince. Either the support cone, as well as the cover in the form of a Cone press-in pin, are made of plastic and set visually compared to the exposed concrete wall. Also as decorative element with appropriate coloring is this Spacers are not very suitable, since there is an exposed concrete wall the plastic discolored under the influence of UV radiation and becomes cloudy.

Ein weiteres Problem, das auch bei der einen Stand der Technik nach Artikel 54(3) EPU bildenden Publikation WO 96/35 032 auftritt, besteht darin, dass die Auflagekonen unter dem Druck der Gewindespindeln, welche die Schalungen zusammenhalten, oftmals leicht deformiert werden. Dabei wird insbesondere das Innenmass des Konuses oft geringfügig verändert, was bereits dazu führt, dass die zapfenförmige Abdeckung nicht mehr in den Auflagekonus eingedrückt werden kann.Another problem that also occurs with publication WO 96/35 032, which forms part of the prior art according to Article 54 (3) EPU, is that the support cones under the pressure of the threaded spindles holding the formwork stick together, often easily deformed. Doing so especially the inner dimension of the cone often changed slightly, which already leads to the cone-shaped cover can no longer be pressed into the support cone.

Aufgrund dieser Erkenntnisse ist es die Aufgabe der vorliegenden Erfindung, einen Abstandhalter zu schaffen, der ästhetisch überzeugt und bei dem die obenerwähnten Probleme nicht mehr oder in erheblich geringerem Masse auftreten können.Based on this knowledge, it is the task of the present Invention to create a spacer that is aesthetic convinced and the above problems are not can occur more or to a much lesser extent.

Diese Aufgabe löst die Erfindung mittels eines Abstandhalters für Schalungen mit den Merkmalen des Patentanspruches 1.The invention achieves this object by means of a spacer for formwork with the features of claim 1.

Weitere vorteilhafte Ausgestaltungsformen gehen aus den abhängigen Patentansprüchen hervor und deren Bedeutung wird in der nachfolgenden Beschreibung dargelegt. Further advantageous embodiments come from dependent claims and their meaning is in the following description.

In der Zeichnung sind einige Ausführungsbeispiele des Erfindungsgegenstandes vereinfacht dargestellt und nachfolgend ausführlich beschrieben.

Zur Erläuterung des erfindungsgemässen Abstandhalters wird vorerst auf die Figuren 2 und 3 Bezug genommen. In der Figur 2 ist die fertig erstellte Betonwand B im Schnitt dargestellt. Vom eigentlichen Distanzhalter verbleibt lediglich das Distanzrohr 1 in der Betonwand B. Bei der Entfernung der Schalung S werden auch die Auflagekonen 2 entfernt. Sind die Auflagekonen mit der Schalung S direkt verbunden, wie dies in der Ausführung gemäss der Figur 3 der Fall ist, so lassen sie sich direkt aus dem Distanzrohr 1 beziehungsweise der Betonwand B herausziehen. Der Auflagekonus 2, der nachfolgend noch genauer beschrieben wird, dient somit als Formstück und in der Wand verbleibt eine Oeffnung 3 entsprechend der Aussenform des Auflagekonuses 2. Ein einsetzbarer Zapfen 4, der bis in das Distanzrohr 1 hineinreicht, wird danach eingepresst. Der einsetzbare Zapfen 4 ist mit der Abdeckung 5 verbunden. Die Abdeckung verschliesst formgenau die Oeffnung 3, welche mit dem Auflagekonus als Formteil in der Betonwand gebildet worden ist.To explain the spacer according to the invention initially referred to Figures 2 and 3. In FIG. 2 the finished concrete wall B is shown in section. All that remains of the actual spacer Spacer tube 1 in the concrete wall B. When removing the Formwork S, the support cones 2 are also removed. Are the Support cones directly connected to the formwork S, as shown in the embodiment according to FIG. 3 is the case, so leave it directly from the spacer tube 1 or the concrete wall B pull out. The support cone 2, the following is described in more detail, thus serves as a fitting and in the An opening 3 remains corresponding to the outer shape of the wall Support cones 2. An insertable pin 4, which into the Distance tube 1 reaches, is then pressed in. The insertable pin 4 is connected to the cover 5. The Cover closes the opening 3, which also with the support cone was formed as a molded part in the concrete wall is.

Der Auflagekonus 2 wird vorteilhafterweise aus Kunststoff gefertigt und weist eine glatte Aussenfläche ohne Hintergriffe und Ausnehmungen auf. Der Auflagekonus 2 besteht aus dem eigentlichen Konuskörper 20, an dessen Basis ein ringförmiger Kragen 21 angeformt ist. Dieser Kragen 21 definiert die Form und Grösse der eigentlichen Abdeckung 5. Auf der Deckfläche 22 des Konus' 20 ist ein zylindrischer Zapfen 23 aufgesetzt, dessen Durchmesser dem Innendurchmesser des Distanzrohres 1 entspricht. Der Durchmesser der Deckfläche 22 ist grösser als der Durchmesser des zylindrischen Zapfens 23 und entspricht mindestens annähernd dem Aussendurchmesser des Distanzrohres 1. So verbleibt von der Deckfläche 22 des Konuskörpers 20 lediglich eine konzentrisch um den zylindrischen Zapfen 23 verlaufende ringförmige Schulter 24.The support cone 2 is advantageously made of plastic manufactured and has a smooth outer surface without handles and recesses. The support cone 2 consists of the actual cone body 20, at the base of an annular Collar 21 is formed. This collar 21 defines the shape and size of the actual cover 5. On the cover surface 22 a conical pin 23 is placed on the cone 20, whose diameter is the inside diameter of the spacer tube 1 equivalent. The diameter of the top surface 22 is larger than the diameter of the cylindrical pin 23 and corresponds at least approximately the outer diameter of the spacer tube 1. So remains of the top surface 22 of the cone body 20th only one concentric around the cylindrical pin 23 extending annular shoulder 24.

Ein derartig gestalteter Auflagekonus 2 lässt sich beidseitig in das Distanzrohr 1 einsetzen und kann so auf dem Bau angeliefert werden. Dank dem ringförmigen Kragen 21 lässt sich der Auflagekonus 2 auch problemlos auf einer Schalung S befestigen. Vorzugsweise erfolgt dies, indem man den Auflagekonus 2 auf die Schalung S aufnagelt. Entsprechend kann der ringförmige Kragen 21 Durchführungslöcher für die Nägel aufweisen.A support cone 2 designed in this way can be used on both sides insert into the spacer tube 1 and can thus on the construction to be delivered. Thanks to the annular collar 21 the support cone 2 can also be easily attached to a formwork S. This is preferably done by using the support cone 2 nailed to the formwork S. Accordingly, the ring-shaped collar 21 through holes for the nails exhibit.

Da der Auflagekonus 2 lediglich als Formteil dient und nach der Erstellung der Betonwand B keine weitere Funktion mehr übernimmt, kann er auch als wiederverwendbares Teil gestaltet sein. Als wiederverwendbares Teil kann er besonders formfest und stabil gefertigt werden und somit äusserst dickwandig oder gar als voller Körper gefertigt werden. Ein solcher Auflagekonus ist besonders formstabil und wird auch unter hohen Druck nicht verformt. Entsprechend ist die Oeffnung 3 auch immer formgenau. Since the support cone 2 serves only as a molded part and after the creation of the concrete wall B no more function takes over, it can also be designed as a reusable part his. As a reusable part, it can be particularly dimensionally stable and be made stable and therefore extremely thick-walled or even be made as a full body. Such a support cone is particularly dimensionally stable and is also under high pressure not deformed. Accordingly, the opening 3 is always dimensionally accurate.

Die Gestaltung des einsetzbaren Zapfens 4 kann unterschiedlich sein. Eine erste Ausführungsform ist in den Figuren 1 und 2 ersichtlich. Die hier dargestellte Variante besteht im wesentlichen aus einem hohlzylindrischen Körper 40, der hier durch eine endständige Zwischenwand 41 abgeschlossen ist. Die Zwischenwand 41 wird von einem Gewindeloch 42 durchsetzt, in das eine Gewindestange 43 eingeschraubt ist. Die Gewindestange 43 ist einseitig durch eine Abplattung 44 zu einer Art Plättchen verbreitert, auf dem die eigentliche Abdeckung 5 aufgeschweisst ist. Der hohlzylindrische Zapfenkörper 40 ist vorzugsweise aus Kunststoff gefertigt und im Bereich, der in das Distanzrohr 1 hineinragt, mit umlaufenden Rückhalterippen 45 versehen. Die Abdeckung 5 wird man vorzugsweise aus einer nichtkorrodierenden Metallplatte fertigen. Zur Vermeidung der Korrosion kann die Metallplatte und die Gewindestange beispielsweise aus rostfreiem Stahl oder anderen, nichtkorrodierenden Metallegierungen bestehen. Die Korrosion kann aber auch durch entsprechende galvanische Beschichtung unterbunden werden. Die Aussenfläche der Abdeckung 5 kann zusätzlich mit einer entsprechend der gewünschten ästhetischen Wirkung farblich gestalteten Beschichtung versehen sein. Vorzugsweise kommt hier ein Kunstharzlack oder eine Emaillierung in Frage. Nicht ausgeschlossen ist jedoch auch ein Aufkleben eines mineralischen Plättchens, beispielsweise aus Marmor oder Granit. The design of the insertable pin 4 can be different his. A first embodiment is shown in FIGS. 1 and 2 seen. The variant shown here consists of essentially of a hollow cylindrical body 40, which here is completed by a terminal partition 41. The Partition wall 41 is penetrated by a threaded hole 42, in that a threaded rod 43 is screwed in. The threaded rod 43 is one-sided by a flattening 44 to a kind Broadened plate on which the actual cover 5 is welded on. The hollow cylindrical pin body 40 is preferably made of plastic and in the area in the spacer tube 1 protrudes with circumferential retaining ribs 45 provided. The cover 5 is preferably one Manufacture non-corroding metal plate. To avoid the Corrosion can, for example, the metal plate and the threaded rod stainless steel or other non-corroding Metal alloys exist. The corrosion can also prevented by appropriate galvanic coating become. The outer surface of the cover 5 can also with a corresponding to the desired aesthetic effect color-coated coating. Preferably a synthetic resin varnish or enamelling can be used here. However, sticking one is not excluded mineral platelets, for example made of marble or Granite.

Da eine Sichtbetonwand nicht unbedingt vollständig eben ist, sondern gewisse Unebenheiten aufweist, ist es sinnvoll, auf der Rückseite der Abdeckung 5 eine gummielastische Scheibe 46 zur Dichtung vorzusehen. Die gummielastische Scheibe 46 kann auf der Abdeckung 5 rückseitig aufgeklebt sein oder zwischen dem hohlzylindrischen Zapfenkörper 40 und der Abdeckung 5 lediglich eingeklemmt werden beim Zusammenschrauben des hohlzylindrischen Zapfenkörpers 40 auf der Gewindestange 43.Since a fair-faced concrete wall is not necessarily completely flat, but has certain bumps, it makes sense to the back of the cover 5 a rubber-elastic disc 46 to provide for the seal. The rubber-elastic disc 46 can be glued to the back of the cover 5 or between the hollow cylindrical pin body 40 and the cover 5 only be pinched when screwing the hollow cylindrical pin body 40 on the threaded rod 43.

In den Figuren 4 bis 6 ist eine Ausbildung des einsetzbaren Zapfens 4 gemäß der Erfindung dargestellt. Auch dieser einsetzbare Zapfen 4 weist einen holhlzylindischen Zapfenkörper 40 mit einer endständigen Zwischenwand 41 auf. Der Zapfenkörper 40 ist aussen wiederum mit radial abstehenden Rückhalterippen 45 versehen zur kraftschlüssigen Halterung des Zapfens im Distanzrohr 1. Auch dieser einsetzbare Zapfen 4 ist aus Kunststoff gefertigt. Im Gegensatz zur vorher beschriebenen Ausführung weist er jedoch keine fest über eine Gewindestange mit dem Zapfenkörper 40 verbundene Abdeckung auf. Vielmehr ist hier der Zapfenkörper 40 mit einer Aufnahme 50 verbunden. Im dargestellten Beispiel ist die Aufnahme 50 einstückig mit dem hohlzylindrischen Zapfenkörper 40 gefertigt. Die dichtende Zwischenwand 41 kann dabei von der Rückseite entfernt soweit nach innen verschoben angeordnet sein, dass der hohlzylindrische Zapfenkörper 40 auf der anderen Endseite verschlossen ist. In diesem Fall bildet die Aufnahme 50 zusammen mit der Zwischenwand 41 eine Art Teller 51. Dieser Teller 51 weist einen umlaufenden, aufstehenden Rand 52 auf, so dass in der Aufnahme 50 mindestens annähernd passgenau eine Abdeckung 5 in Form einer losen Platte 53 eingelegt werden kann. In der einfachsten Form gemäss der Figur 6 kann am aufstehenden Rand 52 eine radial nach innen gerichtete Haltelippe 54 vorgesehen sein. Auf diese Weise lässt sich die Abdeckung 5 als lose Platte 53 in die Aufnahme 50 einfach eindrücken.In Figures 4 to 6 is an embodiment of the usable Pin 4 shown according to the invention. This insertable pin 4 also has a hollow cylindrical pin body 40 with a terminal Partition 41 on. The pin body 40 is in turn on the outside provided with radially projecting retaining ribs 45 for non-positive mounting of the pin in the spacer tube 1. Also this insertable pin 4 is made of plastic. in the Contrary to the previously described version, however, it shows none fixed over a threaded rod with the pin body 40 connected cover. Rather, here is the cone body 40 connected to a receptacle 50. In the example shown is the receptacle 50 in one piece with the hollow cylindrical Pin body 40 made. The sealing partition 41 can removed from the back as far inward be arranged that the hollow cylindrical pin body 40 the other end is closed. In this case forms the receptacle 50 together with the partition 41 a kind Plate 51. This plate 51 has a circumferential, upstanding edge 52 so that in the receptacle 50 at least approximately a cover 5 in the form of a loose plate 53 can be inserted. In the simplest form According to FIG. 6, a radial can be formed on the upstanding edge 52 inward retaining lip 54 may be provided. To this In this way, the cover 5 can be used as a loose plate 53 in the Simply press in holder 50.

In einer bevorzugten Ausführungsform gemäss der Figur 5 ist die Aufnahme 50 zweiteilig gestaltet.
