Description

Die Erfindung betrifft eine Schalungsverbindungsvorrichtung gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a formwork connection device according to the preamble of claim 1.

Eine Schalung ist eine Gussform in welche beispielsweise Frischbeton eingebracht werden kann, um die Form eines Betonkörpers vorzugeben. Es handelt sich hierbei um eine weit verbreitete Technik, welche auf viele verschiedene Arten ausgebildet sein kann.A formwork is a mold in which, for example, fresh concrete can be introduced to specify the shape of a concrete body. It is a widely used technique that can be designed in many different ways.

Eine besondere Herausforderung für die Schalungstechnik sind Rundbauten, also Bauten die im Wesentlichen rund, beispielsweise kreisförmig, ausgebildet sind. Solche Bauten können beispielsweise Silos, Becken oder runde Pfeiler sein. Für solche Bauten muss eine aufwendige Schalung konstruiert werden, welche beispielsweise aus flexiblen Schalungsplatten besteht, welche durch einen geeigneten Hinterbau in die richtige Form gebracht werden.A special challenge for the formwork technology are round constructions, ie buildings which are essentially round, for example circular. Such structures can be for example silos, basins or round pillars. For such buildings a complex formwork must be constructed, which consists for example of flexible shuttering panels, which are brought by a suitable rear triangle in the right shape.

Aus der US 5 044 601 A ist ein Schalungsverbinder bekannt, mit welchem eine Schalung für eine 45° Ecke aufgebaut werden kann. Das Dokument eine Schalungsverbindungsvorrichtung gemäß dem Oberbegriff des Anspruchs 1 offenbart.From the US 5 044 601 A is a formwork connector known with which a formwork for a 45 ° corner can be constructed. The document discloses a formwork connection device according to the preamble of claim 1.

Aus der DE 85 02 232 U1 ist eine Schalungsverbindungsvorrichtung für Rundschalungen mit einem im Wesentlichen U-förmigen Grundkörper bekannt, dessen zwischen zwei seitlichen Flanken befindlicher Quersteg biegsam ausgebildet ist.From the DE 85 02 232 U1 is a formwork connection device for circular formwork with a substantially U-shaped base body is known, which is formed between two lateral flanks crossbar is flexible.

Aus der DE 27 30 542 A1 ist ein Verfahren zur Herstellung einer Schalung bekannt, wobei zwischen zwei Stoßflächen von Schalungselementen ein kalthärtender 2-Komponenten-Elastomer eingefügt wird, welcher im erhärteten Zustand den Schalungsverbinder ausbildet.From the DE 27 30 542 A1 a method for producing a formwork is known, wherein between two abutting surfaces of formwork elements, a cold-curing 2-component elastomer is inserted, which forms the formwork connector in the hardened state.

Aus der US 6 322 046 B1 ist eine Schalungszwinge für den Einsatz bei Ecken bekannt.From the US Pat. No. 6,302,046 B1 is a formwork clamp known for use at corners.

Aus der EP 0 138 196 A2 ist ein Verfahren zur Herstellung einer Rundung mit einer Schalung bekannt.From the EP 0 138 196 A2 is a method for making a rounding with a formwork known.

Aus der US 2006/0156675 A1 ist ein System zur Erzeugung einer im Wesentlichen runden Schalungen bekannt.From the US 2006/0156675 A1 is a system for generating a substantially known round formwork.

Aus der US 4 553 729 A ist ebenfalls ein System zur Erzeugung einer im Wesentlichen runden Schalungen bekannt.From the US 4,553,729 A Also, a system for producing a substantially round formwork is known.

Nachteilig daran ist dass eine derartige Schalung nur mit einem hohen Zeitaufwand konstruiert werden kann, wobei die Konstruktion der Schalung auf die spezielle Anwendung und Form hin ausgelegt werden muss. Eine derartige Schalung ist oft nicht wiederverwertbar und teuer, da qualifiziertes Fachpersonal erforderlich ist.The disadvantage of this is that such a formwork can be constructed only with a great deal of time, the design of the formwork must be designed for the specific application and shape. Such a formwork is often not recyclable and expensive, since qualified specialist personnel is required.

Aufgabe der Erfindung ist es daher eine Schalungsverbindungsvorrichtung der eingangs genannten Art anzugeben, mit welcher die genannten Nachteile vermieden werden können, mit welcher eine Schalung für Rundbauten auf einfache Weise zur Verfügung gestellt werden kann.The object of the invention is therefore to provide a formwork connection device of the type mentioned above, with which the mentioned disadvantages can be avoided, with which a formwork for round buildings can be provided in a simple manner.

Erfindungsgemäß wird dies durch die Merkmale des Patentanspruches 1 erreicht.This is achieved by the features of claim 1 according to the invention.

Dadurch ergibt sich der Vorteil, dass Rahmenschalungselemente zu einer im Wesentlichen runden Schalung zusammengefügt werden können, wodurch ein Aufbau einer Schalung für einen im Wesentlichen runden Betonkörper wesentlich vereinfacht wird. Hierbei bildet die Schalungsverbindungsvorrichtung selber einen Teil der Schalhaut, wodurch verhindert werden kann, dass der noch flüssige Beton durch den Spalt zwischen zwei zueinander verschwenkten Rahmenschalungselementen austritt. Durch die Verbindung mit den Rahmenschalungselementen durch die erste Kopplungsfläche und die zweite Kopplungsfläche kann eine gute stabile Verbindung mit den für eine Rahmenschalung üblichen Verbindungsmitteln erreicht werden. Weiters kann eine derart ausgebildete Schalung gut wiederverwendet werden, im Gegensatz zu einer runden Schalung, welche lediglich für einen bestimmten Einsatzzweck gefertigt wird. Weiters kann eine derartige Schalung schnell von ungeschulten Arbeitern aufgebaut werden.This results in the advantage that frame formwork elements can be assembled to a substantially round formwork, whereby a structure of a formwork for a substantially round concrete body is substantially simplified. Here, the formwork connection device itself forms part of the formwork skin, whereby it can be prevented that the still liquid concrete emerges through the gap between two mutually pivoted frame formwork elements. By connecting with the Frame formwork elements through the first coupling surface and the second coupling surface, a good stable connection can be achieved with the usual formwork for a formwork connection means. Furthermore, such a formwork can be well reused, in contrast to a round formwork, which is made only for a specific purpose. Furthermore, such a formwork can be quickly built by untrained workers.

Eine Schalungsverbindungsvorrichtung 1 dient insbesondere zur Verbindung zweier Rahmenschalungselemente 4, wobei ein erstes Rahmenschalungselement 4 an der ersten Kopplungsfläche 2, und ein zweites Rahmenschalungselement 4 an der zweiten Kopplungsfläche 3 koppelbar ist.The Fig. 1 to 14 show preferred embodiments of a formwork connection device 1, wherein the formwork connection device 1 comprises a first coupling surface 2 and a second coupling surface 3 for coupling with Rahmenschatungselementen 4. A formwork connection device 1 is used in particular for connecting two frame formwork elements 4, wherein a first frame formwork element 4 on the first coupling surface 2, and a second frame formwork element 4 on the second coupling surface 3 can be coupled.

Rahmenschalungselemente 4 sind insbesondere gerade und flächige Elemente eines Rahmenschalungssystems. Solche Rahmenschalungselemente 4 können insbesondere eine ebene Schalhaut aufweisen, welche bevorzugt durch eine ebene Platte ausgebildet ist, welche insbesondere bereits werkseitig fest mit einem Rahmen verbunden, insbesondere verschweißt oder vernietet, ist. Die Schalhaut bezeichnet hierbei jene Fläche, welche dazu vorgesehen ist mit dem Beton in Kontakt zu sein, und welche die Form und Oberflächenstruktur eines Betonkörpers vorgibt. Rahmenschalungssysteme funktionieren nach dem Baukastenprinzip und weisen daher den Vorteil auf, dass diese schnell und von wenigen Personen aufstellbar sind.Frame formwork elements 4 are in particular straight and planar elements of a frame formwork system. Such frame formwork elements 4 may in particular have a flat formwork skin, which is preferably formed by a flat plate, which in particular already factory fixed to a frame, in particular welded or riveted, is. The formwork skin here refers to that surface which is intended to be in contact with the concrete and which defines the shape and surface structure of a concrete body. Frame formwork systems work on the modular principle and therefore have the advantage that they can be set up quickly and by a few people.

Solche Rahmenschalungselemente 4 können insbesondere derart ausgebildet sein, dass mehrere miteinander gekoppelte Rahmenschalungselemente 4 eine ebene Schalhaut bilden. Um solche Rahmenschalungselemente 4 miteinander zu koppeln weisen die Rahmenschalungselemente 4 insbesondere ebene Gegenkopptungsflächen 10 auf, welche normal zu der Fläche der Schalhaut der Rahmenschalungselemente 4 orientiert sein. Um zwei Rahmenschalungselemente 4 miteinander zu koppeln werden die Gegenkopplungsflächen 10 der Rahmenschalungselemente 4 in flächigen Kontakt gebracht, und miteinander verbunden.Such frame formwork elements 4 may in particular be designed such that a plurality of mutually coupled frame formwork elements 4 form a flat formwork skin. In order to couple such frame formwork elements 4 to one another, the frame formwork elements 4 have, in particular, planar countercoupling surfaces 10 which are oriented normal to the surface of the formwork skin of the formwork elements 4. In order to couple two frame formwork elements 4 with each other, the negative feedback surfaces 10 of the frame formwork elements 4 are brought into surface contact, and connected to each other.

Insbesondere können die erste Kopplungsfläche 2 und/oder die zweite Kopplungsfläche 3 eben ausgebildet, und/oder bevorzugt gegengleich zu einer Gegenkopplungsfläche 10 eines Rahmenschalungselementes 4 ausgebildet sein.In particular, the first coupling surface 2 and / or the second coupling surface 3 may be planar, and / or preferably designed to be identical to a counter coupling surface 10 of a frame form element 4.

Es ist vorgesehen, dass die Schalungsverbindungsvorrichtung 1 eine an der ersten Kopplungsfläche 2 und der zweiten Kopplungsfläche 3 angrenzende Schalungsfläche 5 umfasst. Die Schalungsfläche 5 bildet hierbei insbesondere ebenfalls einen Teil der Schalhaut und ist bevorzugt dazu vorgesehen mit dem Beton im direkten Kontakt zu kommen. Insbesondere kann vorgesehen sein, dass die erste Kupplungsfläche 2 und die Schalungsfläche 5, und oder die zweite Kopplungsfläche 3 mit der Schatungsfläche 5 unter Ausbildung einer Kante angrenzen, also dass jeweils ein Ende der ersten Kopplungsfläche 2 und/oder der zweiten Kopplungsfläche 3 an jeweils einem Ende der Schalungsfläche 5 stößt.It is provided that the formwork connection device 1 comprises a formwork surface 5 adjoining the first coupling surface 2 and the second coupling surface 3. The formwork surface 5 forms in this case also in particular a part of the formwork skin and is preferably intended to come into direct contact with the concrete. In particular, it may be provided that the first coupling surface 2 and the shuttering surface 5, and / or the second coupling surface 3 with the shading surface 5 adjacent to form an edge, so that in each case one end of the first coupling surface 2 and / or the second coupling surface 3 at one End of the formwork surface 5 abuts.

Weiters ist vorgesehen, dass die erste Kopplungsfläche 2 und die zweite Kopplungsfläche 3 einen Winkel α einschließen, und dass der Winkel α ein spitzer Winkel ist. Der Winkel α ist dabei jener Winkel, den die Ebenen, in welche die erste Kopplungsfläche 2 oder die zweite Kopplungsfläche 3 angeordnet sind, am Schnittpunkt einschließen. Diese Ebenen können auch als Kopplungsflächenebenen 18 bezeichnet werden.Furthermore, it is provided that the first coupling surface 2 and the second coupling surface 3 enclose an angle α, and that the angle α is an acute angle. The angle α is the angle which the planes in which the first coupling surface 2 or the second coupling surface 3 are arranged enclose at the point of intersection. These planes may also be referred to as coupling surface planes 18.

Dadurch sind zwei Rahmenschatungselemente 4, welche mit der ersten Kopplungsfläche 2 und der zweiten Kopplungsfläche 3 gekoppelt sind, ebenfalls um den Winkel α zueinander verschwenkt. Mit anderen Worten können dadurch die Ebenen, in welchen die Schatungshäute der an der ersten Kopplungsfläche 2 und der zweiten Kopplungsfläche 3 gekoppelten Rahmenschalungselemente 4 angeordnet sind, um den Winkel α zueinander verschwenkt sein.As a result, two Rahmenschatungselemente 4, which are coupled to the first coupling surface 2 and the second coupling surface 3, also pivoted by the angle α to each other. In other words, thereby the planes in which the skins of the at the first coupling surface 2 and the second coupling surface 3 coupled frame formwork elements 4 are arranged to be the angle α pivoted to each other.

Dadurch ergibt sich der Vorteil, dass Rahmenschalungselemente 4 zu einer im Wesentlichen runden Schalung 12 zusammengefügt werden können, wodurch ein Aufbau einer Schalung 12 für einen im Wesentlichen runden Betonkörper wesentlich vereinfacht wird. Hierbei bildet die Schalungsverbindungsvorrichtung 1 selber einen Teil der Schalhaut, wodurch verhindert werden kann, dass der noch flüssige Beton durch den Spalt zwischen zwei zueinander verschwenkten Rahmenschalungselementen 4 austritt. Durch die Verbindung mit den Rahmenschalungselementen 4 durch die erste Kopplungsfläche 2 und die zweite Kopplungsfläche 3 kann eine gute stabile Verbindung mit den für eine Rahmenschalung üblichen Verbindungsmitteln 11 erreicht werden. Weiters kann eine derart ausgebildete Schalung 12 gut wiederverwendet werden, im Gegensatz zu einer runden Schalung, welche lediglich für einen bestimmten Einsatzzweck gefertigt wird. Weiters kann eine derartige Schalung 12 schnell von ungeschulten Arbeitern aufgebaut werden.This results in the advantage that frame formwork elements 4 can be assembled to a substantially round formwork 12, whereby a structure of a formwork 12 is substantially simplified for a substantially round concrete body. Here, the formwork connection device 1 itself forms part of the formwork, whereby it can be prevented that the still liquid concrete exits through the gap between two mutually pivoted frame formwork elements 4. By the connection with the frame formwork elements 4 by the first coupling surface 2 and the second coupling surface 3, a good stable connection with the usual for a frame formwork connection means 11 can be achieved. Furthermore, such a trained formwork 12 can be reused well, in contrast to a round formwork, which is made only for a specific purpose. Furthermore, such a formwork 12 can be constructed quickly by untrained workers.

Insbesondere kann vorgesehen sein, dass die Schalungsverbindungsvorrichtung 1 starr ist, und der Winkel α insbesondere ein fixer Winkel ist, welcher bevorzugt bei der Herstellung der Schalungsverbindungsvorrichtung 1 vorgebbar ist.In particular, it can be provided that the formwork connection device 1 is rigid, and the angle α is in particular a fixed angle, which is preferably predetermined during the production of the formwork connection device 1.

Weiters kann bevorzugt vorgesehen sein, dass die Schalungsverbindungsvorrichtung 1 frei von Spannungen ist, also nicht gespannt oder gebogen werden muss, um den Winkel α zu erreichen, sondern dieser Winkel α bereits vorgegeben ist. Mit anderen Worten kann die Schalungsverbindungsvorrichtung 1 frei von Spannelementen sein, welche den Winkel α vorgeben, indem die Schalungsverbindungsvorrichtung 1 von den Spannelementen in die richtige Form gespannt wird.Furthermore, it can preferably be provided that the formwork connection device 1 is free of stresses, so it does not have to be stretched or bent in order to achieve the angle α, but this angle α is already predetermined. In other words, the formwork connection device 1 can be free of tensioning elements which predetermine the angle α by tensioning the formwork connection device 1 into the correct form by the tensioning elements.

Die Schalungsverbindungsvorrichtung 1 kann generell im Wesentlichen aus jeglichen Material bestehen, welche die statischen Anforderungen genügen, beispielweise Holz oder Kunststoff.The formwork connection device 1 can generally consist essentially of any material that meets the static requirements, such as wood or plastic.

Die Schalungsverbindungsvorrichtung 1 kann insbesondere umfassend Metall, insbesondere Stahl oder Aluminium, ausgebildet sein.

Show these materials particularly preferred mechanical properties.

Besonders bevorzugt kann vorgesehen sein, dass die Schalungsverbindungsvorrichtung 1 als Profilträger ausgebildet ist. Ein Profilträger weist einen über die Länge im Wesentlichen gleichbleibenden Querschnitt auf. Dadurch kann die Schalungsverbindungsvorrichtung 1 besonders einfach ausgebildet und leicht zu handhaben sein.Particularly preferably, it can be provided that the formwork connection device 1 is designed as a profile carrier. A profile carrier has a cross section which is substantially constant over the length. Thereby, the formwork connection device 1 can be particularly simple and easy to handle.

Besonders bevorzugt kann vorgesehn sein, dass die Schalungsverbindungsvorrichtung 1 einstückig ausgebildet ist.Particularly preferred may be provided that the formwork connection device 1 is integrally formed.

Weiters kann bevorzugt vorgesehen sein, dass die Schalungsverbindungsvorrichtung 1 als Hohlkörper ausgebildet ist. Hierbei kann die Schalungsverbindungsvorrichtung 1 eine der Schalungsfläche 5 gegenüber angeordnete Stützwand 17 umfassen. Insbesondere kann die Schalungsverbindungsvorrichtung 1 als Hohlprofil ausgebildet sein. Dadurch kann die Schalungsverbindungsvorrichtung 1 wesentlich stabiler gegenüber einem Verwinden ausgebildet sein.Furthermore, it can preferably be provided that the formwork connection device 1 is formed as a hollow body. Here, the formwork connection device 1 may comprise a formwork surface 5 opposite support wall 17. In particular, the formwork connection device 1 may be formed as a hollow profile. As a result, the formwork connection device 1 can be formed much more stable against twisting.

Alternativ kann vorgesehen sein, dass die Schalungsverbindungsvorrichtung 1 im Wesentlichen hohlraumfrei ausgebildet ist, also beispielsweise als Vollprofil. Im Wesentlichen hohlraumfrei bedeutet in dem Sinne, dass die Schalungsverbindungsvorrichtung 1 bis auf etwaige Aufnahmen frei von Hohlräumen ist.Alternatively it can be provided that the formwork connection device 1 is formed substantially free of cavities, so for example as a solid profile. Substantially cavity-free means in the sense that the formwork connection device 1 is free from any voids except for any receptacles.

Insbesondere kann vorgesehen sein, dass die Schalungsverbindungsvorrichtung 1 als Strangpressprofil ausgebildet ist. Dadurch kann die Schalungsverbindungsvorrichtung 1 besonders einfach mit gleichbleibender Qualität und konstanten Winkel α ausgebildet werden. Weiters können dadurch die Schalungsverbindungsvorrichtung 1 besonders einfach auch als Hohlprofil ausgebildet sein.In particular, it can be provided that the formwork connection device 1 is formed as an extruded profile. As a result, the formwork connection device 1 can be formed in a particularly simple manner with constant quality and constant angle α. Furthermore, the formwork connection device 1 can thereby be designed particularly simply as a hollow profile.

Alternativ kann vorgesehen sein, dass die Schalungsverbindungsvorrichtung 1 als mehrfach abgewinkelte Platte ausgebildet ist. Diese Platte kann beispielsweise aus einer ebenen Platte vorgeformt sein, oder die Schalungsverbindungsvorrichtung 1 kann aus mehreren ebenen Platten zusammengesetzt, insbesondere zusammengeschweißt, sein.Alternatively it can be provided that the formwork connection device 1 is formed as a multi-angled plate. This plate may for example be preformed from a flat plate, or the formwork connection device 1 may be composed of a plurality of flat plates, in particular welded together, be.

Es kann bevorzugt vorgesehen sein, dass die erste Kopplungsfläche 2, und/oder die zweite Kopplungsfläche 3 und/oder die Schalungsfläche 5 rechteckig ausgebildet sind.It can preferably be provided that the first coupling surface 2, and / or the second coupling surface 3 and / or the shuttering surface 5 are rectangular.

Weiters kann vorgesehen sein, dass die Schalungsverbindungsvorrichtung 1 im Bereich der ersten Kopplungsfläche 2, und/oder der zweiten Kopplungsfläche 3 und/oder der Schalungsfläche 5 eine Dicke zwischen 0,2 cm und 3 cm, insbesondere zwischen 0,5 cm und 2 cm, aufweist.Furthermore, it can be provided that the formwork connection device 1 in the region of the first coupling surface 2, and / or the second coupling surface 3 and / or the shuttering surface 5 has a thickness between 0.2 cm and 3 cm, in particular between 0.5 cm and 2 cm, having.

Es kann vorgesehen sein, dass die Schalungsverbindungsvorrichtung 1 eine Höhe zwischen 0,5 m und 6 m, insbesondere zischen 0,75 m und 3 m, aufweist. Weiters kann vorgesehen sein, dass die erste Kopplungsfläche 2, und/oder die zweite Kopplungsfläche 3 eine Breite zwischen 2 cm und 50 cm, insbesondere zwischen 2,5 cm und 20 cm, aufweist.It can be provided that the formwork connection device 1 has a height between 0.5 m and 6 m, in particular between 0.75 m and 3 m. Furthermore, it can be provided that the first coupling surface 2, and / or the second coupling surface 3 has a width between 2 cm and 50 cm, in particular between 2.5 cm and 20 cm.

Besonders bevorzugt kann weiters vorgesehen sein, dass die Schalungsfläche 5 eine Breite zwischen 3 cm und 150 cm aufweist.Particularly preferably, it can further be provided that the shuttering surface 5 has a width between 3 cm and 150 cm.

Hierbei kann die gemäß den bevorzugten Ausführungsformen in Fig. 1 bis Fig. 14 vorgesehen sein, dass die Schalungsfläche 5 eine Breite zwischen 3 cm und 25 cm aufweist, insbesondere zwischen 4 cm und 15 cm, aufweist. Dadurch bildet die Schalungsverbindungsvorrichtung 1 eine Staffel, welche primär dazu dient zwei Rahmenschalungselemente 4 zu verbinden.Here, in accordance with the preferred embodiments in Fig. 1 to Fig. 14 be provided that the shuttering surface 5 has a width between 3 cm and 25 cm, in particular between 4 cm and 15 cm. As a result, the formwork connection device 1 forms a squadron, which serves primarily to connect two frame formwork elements 4.

Alternativ kann vorgesehen sein, dass die Schalungsfläche 5 eine Breite zwischen 20 cm und 150 cm aufweist, insbesondere zwischen 50 cm und 100 cm, aufweist. Dadurch kann die Schalungsverbindungsvorrichtung 1 bereits einen signifikanten Teil Schalhaut bilden.Alternatively it can be provided that the shuttering surface 5 has a width between 20 cm and 150 cm, in particular between 50 cm and 100 cm, has. As a result, the formwork connection device 1 can already form a significant part of formwork skin.

Weiters kann besonders bevorzugt vorgesehen sein, dass der Winkel α kleiner als 30°, insbesondere kleiner als 20°, besonders bevorzugt kleiner als 10°, ist. Durch diesen kleinen Winkel α kann eine kreisrunde Form durch ein Polygon mit vielen Ecken gut angenähert werden, wobei die Annäherung an die Kreisform besser wird, je kleiner der Winkel α ist.Furthermore, it can be particularly preferably provided that the angle α is less than 30 °, in particular less than 20 °, particularly preferably less than 10 °. By this small angle α, a circular shape can be approximated well by a polygon with many corners, the approximation to the circular shape getting better, the smaller the angle α.

Insbesondere kann weiters vorgesehen sein, dass der Winkel α größer als 1°, insbesondere größer als 2°, ist. Dadurch kann die Anzahl der benötigten Schalungsverbindungsvorrichtungen 1 in vorteilhafter Weise gering gehalten werden.In particular, it may further be provided that the angle α is greater than 1 °, especially greater than 2 °, is. Thereby, the number of required formwork connection devices 1 can be kept low in an advantageous manner.

Besonders bevorzugt kann vorgesehen sein, dass der Winkel α ein Bruch von 360° durch eine natürliche Zahl ist. Dadurch können durch eine Mehrzahl gleichartiger Schalungsverbindungsvorrichtung 1 Schalungen 12 gebildet werden, welche eine geschlossene und im Wesentliche runde Form aufweisen. Hierbei kann insbesondere vorgesehen sein, dass diese natürliche Zahl größer als 10, insbesondere größer als 36, besonders bevorzugt größer als 72 ist.Particularly preferably it can be provided that the angle α is a fraction of 360 ° by a natural number. As a result, formworks 12 can be formed by a plurality of similar formwork connection device 1, which have a closed and essentially round shape. In this case, it may in particular be provided that this natural number is greater than 10, in particular greater than 36, particularly preferably greater than 72.

Weiters kann vorgesehen sein, dass ein Winkel zwischen der ersten Kopplungsfläche 2 und der Schalungsfläche 5 gleich ist einem Winkel zwischen der zweiten Kopplungsfläche 3 und der Schalungsfläche 5. Mit anderen Worten, dass die Schalungsverbindungsvorrichtung 1 symmetrisch ist. Dadurch können Fehler beim Aufbau der Schalung 12 vermieden werden, und die Anzahl der verschiedenen Formen der Schalungsverbindungsvorrichtung 1 gering gehalten werden.Furthermore, it can be provided that an angle between the first coupling surface 2 and the shuttering surface 5 is equal to an angle between the second coupling surface 3 and the shuttering surface 5. In other words, the shuttering connection device 1 is symmetrical. As a result, errors in the construction of the formwork 12 can be avoided, and the number of different forms of formwork connection device 1 are kept low.

Die Profile der ersten sechs bevorzugten Ausführungsformen sind in den Fig. 1 bis Fig. 6 dargestellt, wobei in den Fig. 1 bis Fig. 6 die endliche Wandstärke der Schalungsverbindungsvorrichtung 1 lediglich als Strich dargestellt wird.The profiles of the first six preferred embodiments are in FIGS Fig. 1 to Fig. 6 shown, wherein in the Fig. 1 to Fig. 6 the finite wall thickness of the formwork connection device 1 is shown only as a dash.

Die erste und die zweite bevorzugte Ausführungsform, welche in Fig. 1 und Fig. 2 dargestellt sind, weisen ein trapezförmiges geschlossenes Hohlprofil auf. Die erste bevorzugte Ausführungsform unterscheidet sich von der zweiten bevorzugten Ausführungsform durch die Breite der Schalungsfläche 5, und dadurch, dass der Schnittpunkt der Kopplungsflächenebene 18 der ersten Kopplungsfläche 2 und der zweiten Kupplungsfläche 3 in der ersten bevorzugten Ausführungsform an einer der Schalungsfläche 5 zugewandten Seite schneiden, während sich in der zweiten bevorzugten Ausführungsform die Kopplungsflächenebene 18 sich an einer der Schalungsfläche 5 abgewandten Seite schneiden.The first and the second preferred embodiment, which in Fig. 1 and Fig. 2 are shown, have a trapezoidal closed hollow profile. The first preferred embodiment differs from the second preferred embodiment by the width of the shuttering surface 5, and in that the intersection of the coupling surface plane 18 of the first coupling surface 2 and the second coupling surface 3 in the first preferred embodiment intersect on a side facing the shuttering surface 5, while in the second preferred embodiment, the coupling surface plane 18 intersect at a side facing away from the shuttering surface 5.

Die dritte und vierte bevorzugte Ausführungsform in Fig. 3 und Fig. 4 sind im Gegensatz zu der ersten und zweiten bevorzugten Ausführungsform als offenes Hohlprofil ausgebildet.The third and fourth preferred embodiments in FIG. 3 and FIG. 4 are formed as an open hollow profile in contrast to the first and second preferred embodiment.

Die Schalungsfläche 5 ist gemäß den ersten vier bevorzugten Ausführungsformen als ebene Fläche ausgebildet. Dadurch weist die Schalungsverbindungsvorrichtung 1 ein einfaches und leicht zu fertigendes Profil auf.The shuttering surface 5 is formed according to the first four preferred embodiments as a flat surface. As a result, the formwork connection device 1 has a simple and easy-to-manufacture profile.

Alternativ dazu kann vorgesehen sein, dass die Schalungsfläche 5 derart geformt ist, insbesondere durch Knicke und/oder einer Krümmung, dass die Schalungsfläche 5 an der ersten Kopplungsfläche 2 und/oder der zweite Kopplungsfläche 3 rechtwinkelig angrenzt. Mit anderen Worten kann vorgesehen sein, dass die Tangente der Schalungsfläche 5 im Kontaktbereich von Schalungsfläche 5 und Rahmenschalungselement 4 mit der Ebene der Schalhaut des Rahmenschalungselement 4 übereinstimmt. Die fünfte und sechste bevorzugte Ausführungsform, welche in Fig. 5 und 6 dargestellt wird, weist eine derartig ausgebildete Schalungsfläche 5 mit zwei Knicken auf. Dadurch kann der durch eine derartige Schalung 12 hergestellte Betonbauteil eine vorteilhafte Form aufweisen, weil die Kanten nicht an jenen Stellen sind, wo die erste Kopplungsfläche 2 und/oder die zweite Kopplungsfläche 3 mit den Gegenkopplungsflächen 10 gekoppelt waren.Alternatively, it can be provided that the shuttering surface 5 is formed in such a way, in particular by kinks and / or a curvature that the shuttering surface 5 at the first coupling surface 2 and / or the second coupling surface 3 is perpendicular. In other words, it can be provided that the tangent of the shuttering surface 5 in the contact region of the shuttering surface 5 and the frame formwork element 4 coincides with the plane of the shuttering skin of the frame shuttering element 4. The fifth and sixth preferred embodiments, which in FIGS. 5 and 6 is shown, has such a trained formwork surface 5 with two kinks. As a result, the concrete component produced by such a formwork 12 can have an advantageous shape because the edges are not in those locations where the first coupling surface 2 and / or the second coupling surface 3 were coupled to the negative-feedback surfaces 10.

Weiters kann vorgesehen sein, dass die Schalungsfläche 5 an der ersten Kopplungsfläche 2 und/oder der zweite Kopplungsfläche 3 rechtwinkelig angrenzt, und dass die Schalungsfläche 5 eine, insbesondere im Wesentlichen gleichmäßige, Krümmung aufweist. Durch diese, in den Figuren nicht dargestellte, Ausführungsform mit einer gekrümmten Schalungsfläche 5 kann in besonders vorteilhafter Weise ein Betonkörper ohne Kanten an der Rundfläche hergestellt werden.Furthermore, it can be provided that the shuttering surface 5 is perpendicular to the first coupling surface 2 and / or the second coupling surface 3, and that the shuttering surface 5 has a, in particular substantially uniform, curvature. By this, not shown in the figures, embodiment with a curved formwork surface 5, a concrete body without edges on the round surface can be produced in a particularly advantageous manner.

Bevorzugt kann weiters vorgesehen sein, die erste Kopplungsfläche 2 und/oder die zweite Kopplungsfläche 3 Verbindungsmittelaufnahmen 6 aufweisen. Diese Verbindungsmittelaufnahmen 6 können insbesondere als Bohrungen, Durchbrechungen oder Sacklöcher mit oder ohne Gewinde ausgebildet sein. Dadurch kann die Schalungsverbindungsvorrichtung 1 zuverlässig mit Rahmenschalungselementen 4, welche ähnliche Verbindungsmittelaufnahmen 6 aufweisen, gekoppelt werden.Preferably, it can further be provided that the first coupling surface 2 and / or the second coupling surface 3 have connection means receptacles 6. These connecting means receptacles 6 may be formed in particular as holes, openings or blind holes with or without thread. As a result, the formwork connection device 1 can be reliably coupled to frame formwork elements 4 which have similar connection means receptacles 6.

Weiters kann vorgesehen sein, an einer der Schalungsfläche 5 gegenüberliegenden Seite der Schalungsverbindungsvorrichtung 1, also insbesondere an der Stützwand 17, Begrenzungsfortsätze 8 angeordnet sind, zur lagerichtigen Positionierung der Rahmenschalungselemente 4. Diese die Begrenzungsfortsätze 8 ragen hierbei über die erste Kopplungsfläche 2 und/oder die zweite Kopplungsfläche 3 hinaus, wodurch das Rahmenschalungselementen 4 nicht durch den hydrostatischen Druck des Frischbetons weggedrückt werden kann. Dadurch kann die Koppelung von Schalungsverbindungsvorrichtung 1 und Rahmenschalungselementen 4 auch durch Schalungszwingen erfolgen, wobei die Begrenzungsfortsätze 8 insbesondere auch als Anschläge für die Schalungszwingen verwendet werden können.Furthermore, it can be provided on one of the shuttering surface 5 opposite The boundary extensions 8 protrude beyond the first coupling surface 2 and / or the second coupling surface 3, whereby the frame formwork elements 4 not through the hydrostatic pressure of the fresh concrete can be pushed away. As a result, the coupling of formwork connection device 1 and frame formwork elements 4 can also take place by formwork clamps, wherein the boundary extensions 8 can be used in particular as stops for the formwork clamps.

Weiters kann vorgesehen sein, dass die Schalungsverbindungsvorrichtung 1 Ankermittelaufnahmen 7 aufweist. Diese Ankermittelaufnahmen 7 können insbesondere als Durchbrechung, besonders bevorzugt als Bohrung durch die Schalungsfläche 5 ausgebildet sein. Dadurch können zwei Schalungswände 9 mit derartigen Schalungsverbindungsvorrichtung 1 mittels Ankerstangen 16 verbunden werden.Furthermore, it can be provided that the formwork connection device 1 has anchoring means receptacles 7. These anchoring means receptacles 7 may be formed in particular as an opening, particularly preferably as a bore through the formwork surface 5. As a result, two formwork walls 9 can be connected to such formwork connection device 1 by means of anchor rods 16.

Weiters kann insbesondere eine Schalungswand 9 umfassend wenigstens ein Rahmenschalungselement 4 vorgesehen sein, wobei das wenigstens eine Rahmenschalungselement 4 Gegenkopplungsflächen 10 umfasst, wobei die Schalungswand 9 wenigstens eine Schalungsverbindungsvorrichtung 1 gemäß der hier beschriebenen vorteilhaften Art umfasst, und wobei eine der Kopplungsflächen 2,3 der wenigstens einen Schalungsverbindungsvorrichtung 1, also die erste Kopplungsfläche 2 oder die zweite Kopplungsfläche 3, mit einer Gegenkopplungsfläche 10 des wenigstens einen Rahmenschalungselementes 4 verbunden ist.Furthermore, in particular a shuttering wall 9 comprising at least one frame formwork element 4 may be provided, wherein the at least one frame formwork element 4 comprises negative feedback surfaces 10, wherein the shuttering wall 9 comprises at least one formwork connection device 1 according to the advantageous manner described herein, and wherein one of the coupling surfaces 2,3 of the at least a formwork connection device 1, that is, the first coupling surface 2 or the second coupling surface 3, with a negative feedback surface 10 of the at least one frame formwork element 4 is connected.

Insbesondere kann vorgesehen sein, dass die Schalungswand 9 eine vorgebbare Mehrzahl gleicher Schalungsverbindungsvorrichtungen 1 und gleicher Rahmenschalungselementen 4 aufweist, wobei bevorzugt die Anzahl der Schalungsverbindungsvorrichtungen 1 und der Rahmenschalungselemente 4 gleich ist. Dadurch kann eine Schalungswand 9 für im Wesentlichen kreisrunde Rundbauten ausgebildet werden, welche im Wesentlichen aus zwei verschiedenen Elementen besteht, und dementsprechend einfach aufzubauen ist.In particular, it can be provided that the shuttering wall 9 has a predeterminable plurality of identical formwork connection devices 1 and the same frame formwork elements 4, wherein preferably the number of formwork connection devices 1 and the frame formwork elements 4 is the same. As a result, a formwork wall 9 can be formed for substantially circular round structures, which consists essentially of two different elements, and is correspondingly easy to construct.

Alternativ kann vorgesehen sein, dass die Schalungswand 9 wenigstens zwei verschieden geformte Schalungsverbindungsvorrichtung 1 und/oder Rahmenschalungselemente 4 aufweist. Beispielsweise kann durch die Verwendung von Schalungsverbindungsvorrichtung 1 mit unterschiedlichem Winkel α auch eine ovale oder im Wesentlichen parabelförmige Schalungswand 9 ausgebildet sein. Weiters kann, beispielsweise durch die Verwendung einer Schalungsverbindungsvorrichtung 1 der ersten bevorzugten Ausführungsform und der zweiten bevorzugten Ausführungsform in einer Schalungswand 9 eine wellenförmige Schalungswand 9 ausgebildet sein. Auch kann durch die Verwendung von Rahmenschalungselementen 4 mit unterschiedlichen Längen komplexere Formen erreicht werden. Dadurch können generell gekrümmte Flächen durch eine Kombination von unterschiedlich ausgebildeten Schalungsverbindungsvorrichtungen 1 und/oder Rahmenschalungselementen 4 auf einfache Weise angenähert werden.Alternatively it can be provided that the formwork wall 9 at least two differently shaped formwork connection device 1 and / or frame formwork elements 4 has. For example, by the use of formwork connection device 1 with different angles α and an oval or substantially parabolic formwork wall 9 may be formed. Furthermore, for example, by using a formwork connection device 1 of the first preferred embodiment and the second preferred embodiment in a shuttering wall 9, a wave-shaped shuttering wall 9 may be formed. Also, more complex shapes can be achieved by using frame formwork elements 4 of different lengths. As a result, generally curved surfaces can be approximated in a simple manner by a combination of differently configured formwork connection devices 1 and / or frame formwork elements 4.

Weiters kann vorgesehen sein, dass die Schalungswand 9 die Form eines Kreissegmentes aufweist. Dadurch kann beispielsweise ein Betonkörper mit im Wesentlichen rechtwinkeliger Grundriss aber mit abgerundeten Ecken hergestellt werden.Furthermore, it can be provided that the formwork wall 9 has the shape of a circle segment. As a result, for example, a concrete body having a substantially rectangular floor plan but can be made with rounded corners.

Bevorzugt kann weiters vorgesehen sein, dass die wenigstens eine Schalungsverbindungsvorrichtung 1 mit dem wenigstens einen Rahmenschalungselement 4 mittels Verbindungsmitteln 11 lösbar verbunden ist.Preferably, it may further be provided that the at least one formwork connection device 1 is releasably connected to the at least one frame formwork element 4 by means of connecting means 11.

Solche Verbindungsmittel 11 können insbesondere als Schalungszwinge ausgebildet sein.Such connecting means 11 may be formed in particular as a formwork clamp.

Gemäß Fig. 11 und Fig. 12 kann besonders bevorzugt vorgesehen sein, dass das Verbindungsmittel 11 als Gewindestange 19 ausgebildet ist. Gemäß der bevorzugten Ausführungsform in Fig. 11, welche einen Schnitt durch ein Verbindungsmittel 11 darstellt, weisen die Gegenkopplungsflächen 10 der Rahmenschalungselemente 4, sowie die erste Kopplungsfläche 2 und die zweite Kopplungsfläche 3 Bohrungen auf, durch welche die Gewindestange 19 durchragt. Die Gewindestange 19 ist an deren äußeren Ende bevorzugt mittels Schraubmuttern 20 verspannt, wobei die Schraubmuttern 20 die Gegenkopplungsflächen 10 an die erste Kopplungsfläche 2 und die zweite Kopplungsfläche 3 pressen. Weiters können noch Unterlegscheiben 21 vorgesehen sein. Alternativ kann gemäß einer nicht dargestellten Ausführungsform die Gewindestange 19 lediglich an einem Ende mit einer Schraubmutter 20 verspannt, wobei das andere Ende mittels einem Keil fixiert ist. Die Gewindestangen 19, Schraubmuttern 20 und Unterlegscheiben 21 sind zur besseren Übersichtlichkeit in Fig. 12 nicht überall mit Bezugszeichen versehen.According to 11 and FIG. 12 may be particularly preferably provided that the connecting means 11 is formed as a threaded rod 19.
