Definitions

  • the invention relates to a frame part made of wood, plastic and the like according to the preamble of claim 1, an arched window according to claim 10 and a method for producing a frame part according to claim 11.
  • Arched window sashes and arched window frames are composed of several trapezoidal milled segments.
  • the segments are milled with miniature teeth on their inclined faces.
  • the other sides of the segments are planed smooth.
  • the segments are put together with their front sides and glued together to form a polygon.
  • the glued polygon is then provided on the outside and inside with the respective profile of the window sash or window frame on surface processing machines, whereby the arch shape is achieved. Since the glued polygon is still being processed to produce the arch shape, the glued edge does not have to be carried out precisely, as the accuracy is only generated after the last work step. The production of such frame parts is complex and difficult, however.
  • the invention is based on the object of designing the generic frame part, the arched window and the method in such a way that simple, inexpensive and yet precise manufacture is possible.
  • the segments are first completely manufactured, in particular milled, and then firmly connected to one another with the aid of the at least one mechanical connector.
  • the mechanical connector is designed in such a way that it generates a pressing force which acts on the end faces of the segments lying against one another and under which the segments rest against one another with their end faces.
  • the connector is embedded in the segments.
  • the connector forms a pressing unit which is integrated into the frame part and is at a sufficient distance from the outer sides of the segments.
  • the connector preferably extends through the end faces of the segments lying against one another. As a result, the necessary contact pressure is reliably achieved on the end faces, which ensures that the segments lying against one another are firmly pressed against one another.
  • the connector is provided with a pulling part, at least one end of which can be connected to an eccentric. It is housed in the segment in such a way that it can be operated from the outside with a tool. By turning the eccentric, the suspended tension part of the connector is loaded so that the segment connected to the tension part is pulled with its end face firmly against the other segment containing the eccentric.
  • the eccentric can be easily operated with the tool, it is rotatably mounted in a bore in the segments. It extends across the pulling part of the connector. The eccentric is via this hole from the outside easy to reach with the tool. The hole is located at a point on the segments that is not visible from the outside after the frame part has been installed. It is therefore not necessary, for example, to cover the bore after the segments have been pressed together.
  • the tension part of the connector is advantageously located in a longitudinal bore which opens into the end face of the segments and into the bore receiving the eccentric.
  • the pulling part can thus simply be inserted into the longitudinal bore and then connected to the eccentric in the other segment.
  • the end faces of the segments can be flat.
  • the integrated connector ensures that the segments connected to one another lie flat against one another with their end faces under a high pressing force.
  • Such a connection has the advantage that the segments can be detached from one another. For this it is only necessary to turn the eccentric in the opposite direction.
  • a simple alignment of the segments with respect to one another is possible if the end faces are provided with at least one fitting milling in the form of a fitting groove and a feather key to align the segments transversely to their longitudinal direction.
  • the milled fit can be made with a tool sitting on a vertical spindle. The use of the vertical spindle allows a high level of manufacturing precision. With the milled fit, the adjacent segments can be braced against each other without any problems in such a way that no offset and no protrusions or cracks occur in the area of the end faces. In this way, the segments can be joined together seamlessly.
  • the segments are to be permanently connected to one another, it is advantageous if at least one end face of the adjacent segments is provided with an application of adhesive. It can be used for segments with flat faces or with finger teeth.
  • the segments are curved. Such segments are used to manufacture window sashes or window frames for arched windows.
  • the arched window according to the invention is characterized in that it is manufactured with at least one frame part according to the invention. With these frame parts, the arched window can be manufactured inexpensively with high precision.
  • the segments to be assembled are subjected to the required pressing force with at least one connector across their abutting end faces.
  • the connectors thus form pressing units, the pressing force of which ensures that the end faces lying against one another are firmly pressed against one another.
  • the pressing force can be applied optimally when the connector interacts with the segments in the area of the adjacent end faces.
  • the connector is integrated into the segments, a pulling part of the connector being subjected to a pulling force by at least one externally actuatable eccentric, by which the adjacent segments are firmly pressed against each other at their end faces. With this procedure, the connector remains within the frame part.
  • the segments are provided with transverse bores into which the connectors engage from the outside. They are designed in such a way that their connector parts engaging in the transverse bore can be moved towards one another, as a result of which the segments are pressed firmly against one another with their end faces.
  • the segments are provided with an adhesive on their end faces before they are pressed together. With the connector acting from the outside, the segments are pressed firmly against each other. At the latest when the adhesive has set, the connector can be removed.
  • the connectors form small, inexpensive pressing units that can be attached to the segments before the pressing process and removed from them again after the pressing process.
  • the segments have already been completely machined before they are joined. It is therefore no longer necessary to rework the frame part formed from the segments after it has been manufactured.
  • the connector is advantageously removed from the frame part after the adhesive has hardened.
  • Fig. 1 shows part of a round arch which is formed from three arch segments 1 to 3.
  • the round arch forms a frame part of a window sash and has a corresponding sash profile.
  • the round arch can be made from further arch segments.
  • the arc segments 1 to 3 can have the same or unequal length.
  • the arc segments 1 to 3 lie against one another with their end faces.
  • the end faces 4, 5 of the curved sides are each provided with a finger-jointing 6, 7, with which the curved segments 1 to 3 which lie against one another mesh with one another.
  • the finger-joint teeth 6, 7 extend only over part of the height of the arc segments 1 to 3.
  • the finger-joint teeth 6, 7 extend over the thickness of the arc segment 1 to 3. How from Fig.
  • the finger teeth 6, 7 are each spaced from the inside 8 and the outside 9 of the arc segments 1 to 3.
  • the end faces 4, 5 of the arc segments 1 to 3 are provided with an adhesive, so that the arc segments lying against one another are glued to one another.
  • the surface sections 10, 11 ensure that there are clean joints 14, 15 between the arc segments 1 to 3 in the inside 8 as well as in the outside 9 of the round arch.
  • the arc segments 1 to 3 can, however, also be designed in such a way that they have only one of the surface sections or no surface section at all.
  • the finger-joint teeth 6, 7 can be designed in such a way that they are provided over the entire height of the end faces 4, 5. They extend parallel to the inside 8 or outside 9.
  • the adjacent arch segments are each pulled tightly against one another with their end faces 4, 5 by at least one connector.
  • Very high pressing forces can be achieved with the connectors, so that the curved segments 1 to 3 are pressed firmly against one another with their end faces 4, 5. Press forces of over 1000 N are possible.
  • the arch segments 1 to 3 are drawn against each other by two connectors. These connectors are arranged within the arch segments, with a part protruding beyond the end faces 4 and 5, respectively.
  • Fig. 1 pull parts 18, 18 'of two connectors 16, 17 lying one above the other protrude over the end face 5 of the arch segment. They are inserted into the arc segments in such a way that they are in the out of the arc segments formed arches are not visible from the outside.
  • the connectors are spaced from all sides of the arc segments 1 to 3.

  • the two eccentrics 21, 22 are designed identically and have a partially cylindrical jacket 24, 25. Noses 26, 27 protrude from its edge, the partially cylindrical inner surface of which extends eccentrically to the jacket.

Then, as shown in Fig. 1 for the arc segment 1 is indicated, the eccentric is rotated by means of the tool 23 so that the arc segment containing the tension parts 18, 18 'is pulled with its end face firmly against the end face of the adjacent arc segment 3.

The segments are milled with miniature teeth on their inclined faces.

Die anderen Seiten der Segmente sind glatt gehobelt. Die Segmente werden mit ihren Stirnseiten aneinandergesetzt und miteinander zu einem Polygon verleimt. Das verleimte Polygon wird anschließend auf Flächenbearbeitungsmaschinen außen- und innenseitig mit dem jeweiligen Profil des Fensterflügels bzw. Fensterrahmens versehen, wodurch die Bogenform erreicht wird. Da das verleimte Polygon zur Herstellung der Bogenform noch bearbeitet wird, muss die Verleimkante nicht genau ausgeführt werden, da die Genauigkeit erst nach dem letzten Arbeitsschritt erzeugt wird. Die Herstellung solcher Rahmenteile ist allerdings aufwändig und schwierig.The other sides of the segments are planed smooth. The segments are put together with their front sides and glued together to form a polygon. The glued polygon is then provided on the outside and inside with the respective profile of the window sash or window frame on surface processing machines, whereby the arch shape is achieved. Since the glued polygon is still being processed to produce the arch shape, the glued edge does not have to be carried out precisely, as the accuracy is only generated after the last work step. The production of such frame parts is complex and difficult, however.

Aus der FR 2 790 280 A1 ist es bekannt, einen Rundbogen-Rahmenteil über Eckverbinder mit vertikalen Pfosten zu verbinden. Der Rundbogen-Rahmenteil ist einstückig ausgebildet.From the FR 2 790 280 A1 it is known to connect a round arch frame part via corner connectors with vertical posts. The arched frame part is formed in one piece.

Der Erfindung liegt die Aufgabe zugrunde, das gattungsgemäße Rahmenteil, das Rundbogenfenster und das Verfahren so auszubilden, dass eine einfache, kostengünstige und dennoch präzise Herstellung möglich ist.The invention is based on the object of designing the generic frame part, the arched window and the method in such a way that simple, inexpensive and yet precise manufacture is possible.

Diese Aufgabe wird beim gattungsgemäßen Rahmenteil erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruches 1, beim Rundbogenfenster mit den Merkmalen des Anspruches 10 und beim gattungsgemäßen Verfahren erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruches 11 gelöst.This object is achieved in the generic frame part according to the invention with the characterizing features of claim 1, in the arched window with the features of claim 10 and in the generic method according to the invention with the characterizing features of claim 11.

Beim erfindungsgemäßen Rahmenteil werden die Segmente zunächst komplett gefertigt, insbesondere gefräst, und anschließend mit Hilfe des wenigstens einen mechanischen Verbinders fest miteinander verbunden. Der mechanische Verbinder ist so ausgebildet, dass er eine Presskraft erzeugt, die auf die Stirnseiten der aneinander liegenden Segmente wirkt und unter der die Segmente mit ihren Stirnseiten aneinander liegen.In the frame part according to the invention, the segments are first completely manufactured, in particular milled, and then firmly connected to one another with the aid of the at least one mechanical connector. The mechanical connector is designed in such a way that it generates a pressing force which acts on the end faces of the segments lying against one another and under which the segments rest against one another with their end faces.

Von Vorteil ist, wenn der Verbinder in die Segmente eingebettet ist. Der Verbinder bildet eine Presseinheit, die in das Rahmenteil integriert ist und von den Außenseiten der Segmente ausreichenden Abstand hat.It is advantageous if the connector is embedded in the segments. The connector forms a pressing unit which is integrated into the frame part and is at a sufficient distance from the outer sides of the segments.

Bevorzugt erstreckt sich der Verbinder durch die Stirnseiten der aneinander liegenden Segmente hindurch. Dadurch wird auf die Stirnseiten zuverlässig der notwendige Anpressdruck erreicht, durch den sichergestellt ist, dass die aneinander liegenden Segmente fest gegeneinander gedrückt werden.The connector preferably extends through the end faces of the segments lying against one another. As a result, the necessary contact pressure is reliably achieved on the end faces, which ensures that the segments lying against one another are firmly pressed against one another.

Bei einer bevorzugten Ausführungsform ist der Verbinder mit einem Zugteil versehen, von dem mindestens ein Ende mit einem Exzenter verbunden werden kann. Er ist so im Segment untergebracht, dass er von außen mit einem Werkzeug betätigt werden kann. Durch Drehen des Exzenters wird der eingehängte Zugteil des Verbinders so belastet, dass das mit dem Zugteil verbundene Segment mit seiner Stirnfläche fest gegen das andere, den Exzenter enthaltende Segment gezogen wird.In a preferred embodiment, the connector is provided with a pulling part, at least one end of which can be connected to an eccentric. It is housed in the segment in such a way that it can be operated from the outside with a tool. By turning the eccentric, the suspended tension part of the connector is loaded so that the segment connected to the tension part is pulled with its end face firmly against the other segment containing the eccentric.

Damit der Exzenter einfach mit dem Werkzeug betätigt werden kann, ist er in einer Bohrung der Segmente drehbar gelagert. Sie erstreckt sich quer zum Zugteil des Verbinders. Über diese Bohrung ist der Exzenter von außen leicht mit dem Werkzeug zu erreichen. Die Bohrung befindet sich an einer Stelle der Segmente, die nach dem Einbau des Rahmenteiles von außen nicht sichtbar ist. Es ist darum nicht erforderlich, die Bohrung nach dem Zusammenpressen der Segmente beispielsweise abzudecken.So that the eccentric can be easily operated with the tool, it is rotatably mounted in a bore in the segments. It extends across the pulling part of the connector. The eccentric is via this hole from the outside easy to reach with the tool. The hole is located at a point on the segments that is not visible from the outside after the frame part has been installed. It is therefore not necessary, for example, to cover the bore after the segments have been pressed together.

Der Zugteil des Verbinders liegt vorteilhaft in einer Längsbohrung, die in die Stirnseite der Segmente sowie in die den Exzenter aufnehmenden Bohrung mündet. Der Zugteil kann somit einfach in die Längsbohrung eingesetzt und anschließend mit dem Exzenter im anderen Segment verbunden werden.The tension part of the connector is advantageously located in a longitudinal bore which opens into the end face of the segments and into the bore receiving the eccentric. The pulling part can thus simply be inserted into the longitudinal bore and then connected to the eccentric in the other segment.

Die Stirnseiten der Segmente können bei einer einfachen Ausführungsform eben ausgebildet sein. Der integrierte Verbinder stellt hierbei sicher, dass die miteinander verbundenen Segmente mit ihren Stirnseiten unter einer hohen Presskraft flächig aneinander liegen. Eine solche Verbindung hat den Vorteil, dass die Segmente voneinander gelöst werden können. Hierzu ist es lediglich notwendig, den Exzenter in die umgekehrte Richtung zu drehen.In a simple embodiment, the end faces of the segments can be flat. The integrated connector ensures that the segments connected to one another lie flat against one another with their end faces under a high pressing force. Such a connection has the advantage that the segments can be detached from one another. For this it is only necessary to turn the eccentric in the opposite direction.

Es ist auch möglich, die Stirnseiten der Segmente mit einer Keilzinkenverzahnung zu versehen. Benachbarte Segmente greifen dann mit ihren Keilzinkenverzahnungen ineinander. Durch die Keilzinkenverzahnungen ergibt sich eine größere Klebemittelfläche. Auch tragen die Keilzinkenverzahnungen zu einer genauen Fixierung der aneinander liegenden Segmente bei.It is also possible to provide the end faces of the segments with finger teeth. Adjacent segments then mesh with their finger teeth. The finger-joint teeth result in a larger adhesive surface. The finger-joint teeth also contribute to the precise fixation of the adjacent segments.

Eine einfache Ausrichtung der Segmente zueinander ist möglich, wenn die Stirnseiten zur Ausrichtung der Segmente quer zu ihrer Längsrichtung mit mindestens einer Passfräsung in Form einer Passnut und einer Passfeder versehen sind. Die Passfräsung lässt sich mit einem auf einer vertikalen Spindel sitzenden Werkzeug herstellen. Der Einsatz der vertikalen Spindel erlaubt eine hohe Fertigungspräzision. Mit der Passfräsung lassen sich die aneinander liegenden Segmente problemlos so gegeneinander verspannen, dass im Bereich der Stirnseiten kein Versatz und keine Vorsprünge oder Sprünge entstehen. Die Segmente lassen sich auf diese Weise übergangslos zusammenfügen.A simple alignment of the segments with respect to one another is possible if the end faces are provided with at least one fitting milling in the form of a fitting groove and a feather key to align the segments transversely to their longitudinal direction. The milled fit can be made with a tool sitting on a vertical spindle. The use of the vertical spindle allows a high level of manufacturing precision. With the milled fit, the adjacent segments can be braced against each other without any problems in such a way that no offset and no protrusions or cracks occur in the area of the end faces. In this way, the segments can be joined together seamlessly.

Falls die Segmente unlösbar miteinander verbunden werden sollen, ist es vorteilhaft, wenn zumindest die eine Stirnseite der aneinander liegenden Segmente mit einem Klebemittelauftrag versehen ist. Er kann bei Segmenten verwendet werden, deren Stirnseiten eben sind oder mit einer Keilzinkenverzahnung versehen sind.If the segments are to be permanently connected to one another, it is advantageous if at least one end face of the adjacent segments is provided with an application of adhesive. It can be used for segments with flat faces or with finger teeth.

Erfindungsgemäß sind die Segmente gekrümmt ausgebildet. Solche Segmente werden zur Herstellung von Fensterflügeln bzw. Fensterrahmen von Rundbogenfenstern eingesetzt.According to the invention, the segments are curved. Such segments are used to manufacture window sashes or window frames for arched windows.

Das erfindungsgemäße Rundbogenfenster zeichnet sich dadurch aus, dass es mit mindestens einem erfindungsgemäßen Rahmenteil hergestellt ist. Mit diesen Rahmenteilen lässt sich das Rundbogenfenster kostengünstig mit hoher Präzision herstellen.The arched window according to the invention is characterized in that it is manufactured with at least one frame part according to the invention. With these frame parts, the arched window can be manufactured inexpensively with high precision.

Beim erfindungsgemäßen Verfahren werden die zusammenzusetzenden Segmente mit wenigstens einem Verbinder quer zu ihren aneinander liegenden Stirnseiten mit der erforderlichen Presskraft beaufschlagt. Die Verbinder bilden somit Presseinheiten, deren Presskraft sicherstellt, dass die aneinander liegenden Stirnseiten fest gegeneinander gedrückt werden.In the method according to the invention, the segments to be assembled are subjected to the required pressing force with at least one connector across their abutting end faces. The connectors thus form pressing units, the pressing force of which ensures that the end faces lying against one another are firmly pressed against one another.

Die Presskraft lässt sich optimal aufbringen, wenn der Verbinder im Bereich der aneinander liegenden Stirnseiten mit den Segmenten zusammenwirkt. Bei einer vorteilhaften Vorgehensweise wird der Verbinder in die Segmente integriert, wobei durch wenigstens einen von außen betätigbaren Exzenter ein Zugteil des Verbinders einer Zugkraft unterworfen wird, durch welche die aneinander liegenden Segmente an ihren Stirnseiten fest gegeneinander gedrückt werden. Bei dieser Vorgehensweise verbleibt der Verbinder innerhalb des Rahmenteiles.The pressing force can be applied optimally when the connector interacts with the segments in the area of the adjacent end faces. In an advantageous procedure, the connector is integrated into the segments, a pulling part of the connector being subjected to a pulling force by at least one externally actuatable eccentric, by which the adjacent segments are firmly pressed against each other at their end faces. With this procedure, the connector remains within the frame part.

Bei einer anderen vorteilhaften Vorgehensweise sind die Segmente mit Querbohrungen versehen, in die die Verbinder von außen eingreifen. Sie sind so ausgebildet, dass ihre in die Querbohrung eingreifenden Verbinderteile gegeneinander bewegt werden können, wodurch die Segmente mit ihren Stirnseiten fest gegeneinander gedrückt werden.In another advantageous procedure, the segments are provided with transverse bores into which the connectors engage from the outside. They are designed in such a way that their connector parts engaging in the transverse bore can be moved towards one another, as a result of which the segments are pressed firmly against one another with their end faces.

In diesen Fällen werden die Segmente vor dem Zusammenpressen an ihren Stirnseiten mit einem Klebemittel versehen. Mit dem von außen angreifenden Verbinder werden die Segmente fest gegeneinander gepresst. Spätestens wenn das Klebemittel abgebunden hat, kann der Verbinder abgenommen werden.In these cases, the segments are provided with an adhesive on their end faces before they are pressed together. With the connector acting from the outside, the segments are pressed firmly against each other. At the latest when the adhesive has set, the connector can be removed.

Bei einer solchen Verfahrensweise bilden die Verbinder kleine, kostengünstige Presseinheiten, die vor dem Pressvorgang an die Segmente angesetzt und nach dem Pressvorgang von ihnen wieder abgenommen werden können.With such a procedure, the connectors form small, inexpensive pressing units that can be attached to the segments before the pressing process and removed from them again after the pressing process.

Beim erfindungsgemäßen Verfahren können mehrere Segmente unmittelbar nacheinander miteinander verbunden werden. Es ist nicht notwendig, das Abtrocknen des Klebemittels an der einen Verbindungsstelle abzuwarten und erst dann die nächste Verbindungsstelle herzustellen. Mit den Verbindern können alle Segmente des Rahmenteiles gleichzeitig mittels der Verbinder unter hoher Presskraft gegeneinander gedrückt werden.In the method according to the invention, several segments can be connected to one another in direct succession. It is not necessary to wait for the adhesive to dry at one connection point and only then make the next connection point. With the connectors, all segments of the frame part can be pressed against each other at the same time by means of the connectors with high pressing force.

Bei einer bevorzugten Ausführungsform sind die Segmente vor dem Zusammenfügen bereits fertig bearbeitet. Es ist darum nicht mehr notwendig, das aus den Segmenten gebildete Rahmenteil nach seiner Herstellung noch nachzubearbeiten.In a preferred embodiment, the segments have already been completely machined before they are joined. It is therefore no longer necessary to rework the frame part formed from the segments after it has been manufactured.

Vorteilhaft wird der Verbinder nach dem Aushärten des Klebemittels vom Rahmenteil abgenommen.The connector is advantageously removed from the frame part after the adhesive has hardened.

Fig. 1 zeigt einen Teil eines Rundbogens, der aus drei Bogensegmenten 1 bis 3 gebildet ist. Der Rundbogen bildet einen Rahmenteil eines Fensterflügels und hat ein entsprechendes Flügelprofil. Der Rundbogen kann aus weiteren Bogensegmenten hergestellt sein. Die Bogensegmente 1 bis 3 können gleiche, aber auch ungleiche Länge haben. Die Bogensegmente 1 bis 3 liegen mit ihren Stirnseiten aneinander. Im dargestellten Ausführungsbeispiel sind die Stirnseiten 4, 5 der Bogenseiten jeweils mit einer Keilzinkenverzahnung 6, 7 versehen, mit denen die aneinanderliegenden Bogensegmente 1 bis 3 ineinandergreifen. Die Keilzinkenverzahnungen 6, 7 erstrecken sich nur über einen Teil der Höhe der Bogensegmente 1 bis 3. Die Keilzinkenverzahnungen 6, 7 erstrecken sich über die Dicke des Bogensegmentes 1 bis 3. Wie aus Fig. 1 hervorgeht, haben die Keilzinkenverzahnungen 6, 7 jeweils Abstand von der Innenseite 8 und der Außenseite 9 der Bogensegmente 1 bis 3. Dadurch werden ebene Flächenabschnitte 10, 11 gebildet, die sich zwischen der Unterseite 12 und der Oberseite 13 der Bogensegmente 1 bis 3 erstrecken. Die Stirnseiten 4, 5 der Bogensegmente 1 bis 3 werden mit einem Klebemittel versehen, so dass die aneinanderliegenden Bogensegmente miteinander verklebt werden. Durch die Flächenabschnitte 10, 11 wird sichergestellt, dass sich in der Innenseite 8 sowie in der Außenseite 9 des Rundbogens saubere Fugen 14, 15 zwischen den Bogensegmenten 1 bis 3 ergeben. Fig. 1 shows part of a round arch which is formed from three arch segments 1 to 3. The round arch forms a frame part of a window sash and has a corresponding sash profile. The round arch can be made from further arch segments. The arc segments 1 to 3 can have the same or unequal length. The arc segments 1 to 3 lie against one another with their end faces. In the exemplary embodiment shown, the end faces 4, 5 of the curved sides are each provided with a finger-jointing 6, 7, with which the curved segments 1 to 3 which lie against one another mesh with one another. The finger-joint teeth 6, 7 extend only over part of the height of the arc segments 1 to 3. The finger-joint teeth 6, 7 extend over the thickness of the arc segment 1 to 3. How from Fig. 1 As can be seen, the finger teeth 6, 7 are each spaced from the inside 8 and the outside 9 of the arc segments 1 to 3. This creates flat surface sections 10, 11 which extend between the bottom 12 and the top 13 of the arc segments 1 to 3. The end faces 4, 5 of the arc segments 1 to 3 are provided with an adhesive, so that the arc segments lying against one another are glued to one another. The surface sections 10, 11 ensure that there are clean joints 14, 15 between the arc segments 1 to 3 in the inside 8 as well as in the outside 9 of the round arch.

Die Bogensegmente 1 bis 3 können aber auch so gestaltet sein, dass sie nur einen der Flächenabschnitte oder gar keinen Flächensabschnitt aufweisen. Die Keilzinkenverzahnungen 6, 7 können so gestaltet sein, dass sie über die gesamte Höhe der Stirnseiten 4, 5 vorgesehen sind. Sie erstrecken sich parallel zur Innenseite 8 bzw. Außenseite 9.The arc segments 1 to 3 can, however, also be designed in such a way that they have only one of the surface sections or no surface section at all. The finger-joint teeth 6, 7 can be designed in such a way that they are provided over the entire height of the end faces 4, 5. They extend parallel to the inside 8 or outside 9.

Damit die Bogensegmente 1 bis 3 einwandfrei über das Klebemittel miteinander verbunden werden können, werden die benachbarte Bogensegmente durch jeweils mindestens einen Verbinder mit ihren Stirnseiten 4, 5 fest gegeneinander gezogen. Mit den Verbindern lassen sich sehr hohe Presskräfte erzielen, so dass die Bogensegmente 1 bis 3 mit ihren Stirnseiten 4, 5 fest gegeneinander gedrückt werden. Es sind Presskräfte bis über 1000 N möglich.So that the arch segments 1 to 3 can be connected to one another properly via the adhesive, the adjacent arch segments are each pulled tightly against one another with their end faces 4, 5 by at least one connector. Very high pressing forces can be achieved with the connectors, so that the curved segments 1 to 3 are pressed firmly against one another with their end faces 4, 5. Press forces of over 1000 N are possible.

Beim Ausführungsbeispiel gemäß Fig. 1 werden die Bogensegmente 1 bis 3 durch jeweils zwei Verbinder gegeneinander gezogen. Diese Verbinder sind innerhalb der Bogensegmente angeordnet, wobei ein Teil über die Stirnseiten 4 bzw. 5 vorsteht. In Fig. 1 stehen über die Stirnseite 5 des Bogensegmentes Zugteile 18, 18' zweier übereinander liegender Verbinder 16, 17 vor. Sie sind so in die Bogensegmente eingesetzt, dass sie in dem aus den Bogensegmenten gebildeten Rundbogen von außen nicht sichtbar sind. Die Verbinder haben Abstand von allen Seiten der Bogensegmente 1 bis 3.In the embodiment according to Fig. 1 the arch segments 1 to 3 are drawn against each other by two connectors. These connectors are arranged within the arch segments, with a part protruding beyond the end faces 4 and 5, respectively. In Fig. 1 pull parts 18, 18 'of two connectors 16, 17 lying one above the other protrude over the end face 5 of the arch segment. They are inserted into the arc segments in such a way that they are in the out of the arc segments formed arches are not visible from the outside. The connectors are spaced from all sides of the arc segments 1 to 3.

Anhand von Fig. 2 wird das Funktionsprinzip des Verbinders 16, 17 erläutert. Er hat einen Zugteil 18, der mit beiden Enden 19, 20 in jeweils einen Exzenter 21, 22 eingehängt ist. Die Exzenter 21, 22 sind so in den Bogensegmenten 1 bis 3 angeordnet, dass sie mit einem Werkzeug 23, im Ausführungsbeispiel mit einem Schraubendreher, betätigt werden können. Die beiden Exzenter 21, 22 sind gleich ausgebildet und haben einen teilzylindrischen Mantel 24, 25. Von seinem Rand stehen Nasen 26, 27 ab, deren teilzylindrische Innenfläche zum Mantel exzentrisch verläuft. Die Nasen begrenzen eine Einhängeöffnung für das Ende 19, 20 des Zugteils 18. Die Enden 19, 20 sind vorteilhaft kegelförmig bzw. kugelförmig ausgebildet und erweitern sich in Richtung auf ihr freies Ende. Der Abstand der beiden Zungen 26, 27, in Achsrichtung des Exzenters 21, 22 gesehen, ist kleiner als der maximale Durchmesser der Enden 19, 20 des Zugteiles 18.Based on Fig. 2 the functional principle of the connector 16, 17 is explained. It has a pulling part 18, which is hung with both ends 19, 20 in an eccentric 21, 22 each. The eccentrics 21, 22 are arranged in the arc segments 1 to 3 in such a way that they can be actuated with a tool 23, in the exemplary embodiment with a screwdriver. The two eccentrics 21, 22 are designed identically and have a partially cylindrical jacket 24, 25. Noses 26, 27 protrude from its edge, the partially cylindrical inner surface of which extends eccentrically to the jacket. The noses delimit a suspension opening for the end 19, 20 of the pulling part 18. The ends 19, 20 are advantageously conical or spherical and widen in the direction of their free end. The distance between the two tongues 26, 27, seen in the axial direction of the eccentric 21, 22, is smaller than the maximum diameter of the ends 19, 20 of the pulling part 18.

Die Exzenter 21, 22 sind so an den Bogensegmenten 1 bis 3 vorgesehen, dass ihre durch eine Scheibe gebildete Stirnseite 28, 29 in der Unterseite 12 der Bogensegmente 1 bis 3 liegt. Die Stirnseiten 28, 29 sind mit einer Eingriffsvertiefung 30, 31 für das Werkzeug 23 versehen.The eccentrics 21, 22 are provided on the arc segments 1 to 3 in such a way that their end face 28, 29 formed by a disk lies in the underside 12 of the arc segments 1 to 3. The end faces 28, 29 are provided with an engagement recess 30, 31 for the tool 23.

Wird in Fig. 2 der Exzenter 21 mittels des Werkzeuges 23 in Richtung des Pfeils gedreht, wird der Zugteil 18 infolge des Eingriffes des Endes 19 in die exzentrischen Naseninnenflächen des Exzenters 21 entsprechend verschoben, weil die Nasen 26, 27 mit dem Exzenter 21 bewegt werden. Da die beiden Exzenter in benachbarten Bogensegmenten vorgesehen sind, wird durch Drehen des Exzenters 21 das den Exzenter 20 enthaltende Bogensegment mit seiner Stirnseite fest gegen das den Exzenter 21 enthaltende Bogenelement gezogen.Is in Fig. 2 If the eccentric 21 is rotated by means of the tool 23 in the direction of the arrow, the pulling part 18 is displaced accordingly as a result of the engagement of the end 19 in the eccentric inner nose surfaces of the eccentric 21, because the lugs 26, 27 are moved with the eccentric 21. Since the two eccentrics are provided in adjacent arc segments, the arc segment containing the eccentric 20 is pulled with its end face firmly against the arc element containing the eccentric 21 by rotating the eccentric 21.

Bei der Ausführungsform nach Fig. 1 haben die beiden Verbinder 16, 17 jeweils nur einen Exzenter 21, 22. Die Zugteile 18, 18' der beiden Verbinder 16, 17 sind in den benachbarten Bogensegmenten befestigt, beispielsweise eingeschraubt. Wie Fig. 1 für das Bogensegment 1 zeigt, stehen die Zugteile 18, 18' der beiden Verbinder 16, 17 über die Stirnseite 5 des Bogensegmentes 1 vor. Die gegenüberliegende Stirnseite 6 des anzuschließenden Bogensegmentes hat in die Stirnseite mündende Bohrungen 32, 33, wie dies für das Bogensegment 3 dargestellt ist. Die Bohrungen 32, 33 liegen senkrecht zur Stirnseite 4 des Bogensegmentes 3. In die Bohrungen 32, 33 münden Querbohrungen 34, 35, die in die Unterseite 12 des Bogensegmentes 3 münden. Durch die Querbohrungen 34, 35 wird der Exzenter 22 gesteckt. Er wird hierbei so in der Querbohrung 34, 35 gedreht, dass die Zugteile 18, 18' mit ihren Enden 20 zwischen die Nasen 26, 27 der Exzenter 22 gelangen können. Anschließend wird, wie dies in Fig. 1 für das Bogensegment 1 angedeutet ist, der Exzenter mittels des Werkzeuges 23 so gedreht, dass das die Zugteile 18, 18' enthaltende Bogensegment mit seiner Stirnseite fest gegen die Stirnseite des benachbarten Bogensegmentes 3 gezogen wird. Werden die Exzenter des Bogensegmentes 1 entsprechend betätigt, wird auf diese Weise das Bogensegment 2 mit seiner Stirnseite 5 gegen die Stirnseite 4 des Bogensegmentes 1 gezogen. In gleicher Weise wird durch Betätigung der Exzenter im Bogensegment 2 das Bogensegment 3 gegen das Bogensegment 2 gezogen. Auf diese Weise können die Bogensegmente 1 bis 3 nacheinander mit hoher Kraft gegeneinander gepresst werden, so dass eine zuverlässige Verklebung der Bogensegmente 1 bis 3 an ihren Stirnseiten 4, 5 gewährleistet ist. Die Stirnseiten 4, 5 der Bogensegmente 1 bis 3 werden vor dem Zusammenziehen der Bogensegmente mit dem entsprechenden Klebemittel beaufschlagt. Die Bogensegmente 1 bis 3 werden passgenau zusammengefügt und mit Hilfe des Werkzeuges 23 in der beschriebenen Weise stirnseitig zusammengepresst.In the embodiment according to Fig. 1 the two connectors 16, 17 each have only one eccentric 21, 22. The pulling parts 18, 18 'of the two connectors 16, 17 are fastened, for example screwed, in the adjacent arch segments. How Fig. 1 for the arch segment 1 shows, the tension parts 18, 18 'of the two connectors 16, 17 protrude beyond the end face 5 of the arch segment 1. The opposite end face 6 of the arc segment to be connected has bores 32, 33 opening into the end face, as is shown for the arc segment 3. The bores 32, 33 are perpendicular to the end face 4 of the arc segment 3. Transverse bores 34, 35 which open into the underside 12 of the arc segment 3 open into the bores 32, 33. The eccentric 22 is inserted through the transverse bores 34, 35. It is rotated in the transverse bore 34, 35 in such a way that the ends 20 of the pulling parts 18, 18 ′ can get between the lugs 26, 27 of the eccentrics 22. Then, as shown in Fig. 1 for the arc segment 1 is indicated, the eccentric is rotated by means of the tool 23 so that the arc segment containing the tension parts 18, 18 'is pulled with its end face firmly against the end face of the adjacent arc segment 3. If the eccentrics of the arc segment 1 are actuated accordingly, the arc segment 2 is pulled with its end face 5 against the end face 4 of the arc segment 1. In the same way, by actuating the eccentric in the arc segment 2, the arc segment 3 is drawn against the arc segment 2. In this way, the arch segments 1 to 3 can be pressed against one another with great force, one after the other, so that reliable gluing of the arch segments 1 to 3 on their end faces 4, 5 is ensured. The end faces 4, 5 of the arc segments 1 to 3 are acted upon with the appropriate adhesive before the arc segments are drawn together. The arc segments 1 to 3 are fitted together with an exact fit and the end faces are pressed together with the aid of the tool 23 in the manner described.

Die Bohrungen 32, 33 werden mittels eines Winkelkopfes in die Stirnseiten 4, 5 der Bogensegmente eingebracht. Der Durchmesser der Bohrungen 32, 33 ist größer als der Durchmesser der Zugteile 18, 18', so dass sie einfach eingesetzt werden können. Aufgrund des größeren Durchmessers der Bohrungen 32, 33 ist es nicht von Bedeutung, dass der Winkelkopf nur eine geringe Fertigungstoleranz erlaubt.The bores 32, 33 are made in the end faces 4, 5 of the arc segments by means of an angle head. The diameter of the bores 32, 33 is larger than the diameter of the pulling parts 18, 18 ', so that they can be easily inserted. Due to the larger diameter of the holes 32, 33 it is not important that the angle head allows only a small manufacturing tolerance.

Zudem hat der größere Bohrungsdurchmesser den Vorteil, dass vor dem Zusammenpressen die Bogensegmente von Hand so gegeneinander ausgerichtet werden können, dass sie lückenlos und ohne Sprung oder Versatz aneinander liegen. Dann werden die Bogensegmente gegeneinander verpresst.In addition, the larger bore diameter has the advantage that, prior to being pressed together, the arc segments can be aligned with one another by hand so that they lie against one another without any gaps and without any cracks or misalignments. Then the arch segments are pressed against each other.

Aufgrund der Verspannung der Bogensegmente 1 bis 3 nacheinander muss nicht gewartet werden, bis das Klebemittel der letzten Verbindungsstelle getrocknet ist. Auch wenn das Klebemittel noch nicht abgebunden hat, kann bereits das nächste Bogensegment angefügt und mit Hilfe der Verbinder 16, 17 gegen das benachbarte Bogensegment verspannt werden.Due to the tensioning of the arch segments 1 to 3 one after the other, there is no need to wait until the adhesive of the last connection point has dried. Even if the adhesive has not yet set, the next arch segment can already be attached and braced against the adjacent arch segment with the aid of the connectors 16, 17.

Da die Verbinder 16, 17 in dem durch die Bogensegmente 1 bis 3 gebildeten Rundbogen verbleiben, ist ein Klebemittelauftrag auf die Stirnseiten 4, 5 nicht zwingend notwendig. Die Verbinder 16, 17 gewährleisten durch die hohen Presskräfte, die über 1000 N betragen können, dass die Bogensegmente 1 bis 3 auch ohne Klebmittel fest miteinander verbunden sind. Der Einsatz des Klebemittels hat allerdings den Vorteil, dass benachbarte Bogensegmente 1 bis 3 fest miteinander verbunden bleiben, selbst wenn die von den Verbindern 16, 17 ausgeübte Presskraft nachlassen oder sogar gegen Null gehen sollte.Since the connectors 16, 17 remain in the round arch formed by the arch segments 1 to 3, an application of adhesive to the end faces 4, 5 is not absolutely necessary. The connectors 16, 17 ensure through the high pressing forces, which can be over 1000 N, that the arch segments 1 to 3 are firmly connected to one another even without adhesive. The use of the adhesive, however, has the advantage that adjacent arc segments 1 to 3 remain firmly connected to one another, even if the pressing force exerted by the connectors 16, 17 should decrease or even approach zero.

Die die Exzenter aufnehmenden Querbohrungen 34, 35 haben ausreichenden Abstand von der Stirnseite 4 der Bogensegmente 1 bis 3, so dass eine Beeinträchtigung oder Beschädigung der Stirnseiten bzw. der dort vorgesehenen Keilzinkenverzahnungen vermieden wird.The transverse bores 34, 35 accommodating the eccentrics are at a sufficient distance from the end face 4 of the arc segments 1 to 3, so that impairment or damage to the end faces or the finger teeth provided there is avoided.

Die Bogensegmente 1 bis 3 sind in ihren beiden Seiten 12, 13 profiliert, je nach gewünschtem Endprofil des Rundbogens.The arch segments 1 to 3 are profiled in their two sides 12, 13, depending on the desired end profile of the arch.

Die in Fig. 2 dargestellten Verbinder werden bei der Ausführungsform gemäß den Fig. 3 und 4 eingesetzt. Benachbarte Bogensegmente 1, 2 werden durch zwei übereinanderliegende Verbinder 16, 17 in der beschriebenen Weise gegeneinander gezogen. Jeder Verbinder hat den Zugteil 18, der mit seinen Enden 19, 20 in die Exzenter 21, 22 eingehängt ist. Mit dem Werkzeug 23 werden beide Exzenter 21, 22 des jeweiligen Verbinders 16, 17 so mit dem Werkzeug 23 gedreht, dass über den Zugteil 18 die beiden aneinanderliegenden Bogensegmente 1, 2 mit hoher Presskraft gegeneinander gedrückt werden. Die beiden Exzenter 21, 22 der Verbinder 16, 17 haben jeweils ausreichenden Abstand von den Stirnseiten 4, 5 der Bogensegmente 1, 2. Die Zugteile 18 der Verbinder 16, 17 liegen in Vertiefungen 36, 37, 38, 39, die in den Unterseiten 12 der Bogensegmente 1, 2 vorgesehen sind. Die Vertiefungen 36, 38 und 37, 39 liegen mit Abstand übereinander. Da die Vertiefungen 36 bis 39 zur Außenseite 12 offen sind, lassen sich die Verbinder 16, 17 mit den Zugteilen 18, 18' problemlos montieren. Die Exzenter 21, 22 werden in die Querbohrungen 34, 35 eingesetzt, in welche die Vertiefungen münden. Die Querbohrungen 34, 35 sind tiefer als die Vertiefungen 36 bis 39 (Fig. 4), so dass die Exzenter 21, 22 ausreichend tief in die Bogensegmente 1, 2 eingesetzt werden können. Mit dem Werkzeug 23 wird einer der beiden Exzenter jedes Verbinders 16, 17 in der jeweiligen Richtung so gedreht, dass die Bogensegmente 1, 2 mit ihren Stirnseiten 4, 5 fest gegeneinander gezogen werden. Sobald die Klebeverbindung ausgehärtet ist, können die Verbinder 16, 17 aus den Vertiefungen 36 bis 39 sowie den Querbohrungen 34, 35 entfernt werden.In the Fig. 2 The connectors shown are in the embodiment according to FIGS Figs. 3 and 4 used. Adjacent arc segments 1, 2 are drawn towards one another in the manner described by two connectors 16, 17 lying one above the other. Each connector has the pulling part 18, which is suspended with its ends 19, 20 in the eccentrics 21, 22. With the tool 23, both eccentrics 21, 22 of the respective connector 16, 17 are rotated with the tool 23 that the two adjacent arc segments 1, 2 are pressed against one another with a high pressing force via the pulling part 18. The two eccentrics 21, 22 of the connectors 16, 17 each have a sufficient distance from the end faces 4, 5 of the arc segments 1, 2. The pulling parts 18 of the connectors 16, 17 lie in recesses 36, 37, 38, 39 in the undersides 12 of the arc segments 1, 2 are provided. The recesses 36, 38 and 37, 39 are spaced one above the other. Since the recesses 36 to 39 are open to the outside 12, the connectors 16, 17 can be assembled with the pulling parts 18, 18 'without any problems. The eccentrics 21, 22 are inserted into the transverse bores 34, 35 into which the depressions open. The transverse bores 34, 35 are deeper than the recesses 36 to 39 ( Fig. 4 ), so that the eccentrics 21, 22 can be inserted sufficiently deep into the arc segments 1, 2. With the tool 23, one of the two eccentrics of each connector 16, 17 is rotated in the respective direction so that the curved segments 1, 2 with their end faces 4, 5 are pulled tightly against one another. As soon as the adhesive connection has hardened, the connectors 16, 17 can be removed from the recesses 36 to 39 and the transverse bores 34, 35.

Wie bei der vorigen Ausführungsform sind die Verbinder 16, 17 so angeordnet, dass ein gleichmäßiger Anpressdruck über die gesamte Fläche der Stirnseiten 4, 5 gewährleistet ist.As in the previous embodiment, the connectors 16, 17 are arranged in such a way that a uniform contact pressure is ensured over the entire surface of the end faces 4, 5.

Abweichend von der dargestellten Ausführungsform ist es auch möglich, die beiden Verbinder 16, 17 versenkt in den Bogensegmenten 1, 2 unterzubringen, wie dies beispielhaft bei der Ausführungsform gemäß Fig. 1 vorgesehen ist. In diesem Falle können die Exzenter 21, 22 von außen durch die Querbohrungen 34, 35 der beiden Bogensegmente 1, 2 eingesteckt und dann so gedreht werden, dass sich die Zugteile 18 in die Nasen 26, 27 der Exzenter einhängen lassen.Deviating from the embodiment shown, it is also possible to accommodate the two connectors 16, 17 sunk in the arch segments 1, 2, as is done by way of example in the embodiment according to FIG Fig. 1 is provided. In this case, the eccentrics 21, 22 from the outside through the Transverse bores 34, 35 of the two curved segments 1, 2 are inserted and then rotated so that the pulling parts 18 can be hooked into the lugs 26, 27 of the eccentric.

Abweichend vom dargestellten Ausführungsbeispiel kann der Verbinder nur den Exzenter 22 aufweisen. Anstelle des Exzenters 21 wird ein Halteteil verwendet, der lösbar, aber auch fest mit dem Zugteil 18 verbunden sein kann, so dass der Zugteil 18 und der Halteteil zusammen in das Bogensegment 2 eingesetzt werden können. Durch Drehen des Exzenters 22 wird der Zugteil 18 verschoben und über seinen Halteteil das Bogensegment 2 gegen das Bogensegment 1 gedrückt.In a departure from the exemplary embodiment shown, the connector can only have the eccentric 22. Instead of the eccentric 21, a holding part is used which can be detachably but also firmly connected to the pulling part 18, so that the pulling part 18 and the holding part can be inserted together into the arch segment 2. By rotating the eccentric 22, the pulling part 18 is displaced and the arched segment 2 is pressed against the arched segment 1 via its holding part.

Beim Ausführungsbeispiel nach den Fig. 5 und 6 wird zum Verspannen der Bogensegmente 1, 2 gegeneinander ein Verbinder 40 eingesetzt, der als Hebelverbinder ausgebildet ist. Der Verbinder 40 hat zwei gegeneinander verschwenkbare L-förmige Hebelteile 41, 42, die über einen Bolzen 43 gelenkig miteinander verbunden sind. Sie haben jeweils einen Schenkel 44, 45, der am freien Ende von einem Bolzen 46, 47 durchsetzt ist. Die überstehenden Bolzenteile ragen in Vertiefungen 48, 49, die in den Unterseiten 12 der Bogensegmente 1, 2 benachbart zu den Stirnflächen 4, 5 der Bogensegmente 1, 2 vorgesehen sind. Im Schenkel 50 des Hebelteils 42 befindet sich eine Gewindebohrung 51, in die eine Sechskantschraube 52 geschraubt ist. Er durchsetzt den Schenkel 50 und liegt mit seinem freien Ende auf einer Schulterfläche 53 des Schenkels 44 des Hebelteiles 41 auf (Fig. 5).In the embodiment according to the Figures 5 and 6 a connector 40, which is designed as a lever connector, is used to brace the arch segments 1, 2 against one another. The connector 40 has two L-shaped lever parts 41, 42 which can be pivoted relative to one another and which are connected to one another in an articulated manner via a bolt 43. They each have a leg 44, 45 through which a bolt 46, 47 passes at the free end. The protruding bolt parts protrude into recesses 48, 49, which are provided in the undersides 12 of the arc segments 1, 2 adjacent to the end faces 4, 5 of the arc segments 1, 2. In the leg 50 of the lever part 42 there is a threaded bore 51 into which a hexagon screw 52 is screwed. It passes through the leg 50 and rests with its free end on a shoulder surface 53 of the leg 44 of the lever part 41 ( Fig. 5 ).

Der Gewindebolzen 52 steht über die beiden Hebelteile 41, 42 vor, so dass auf den Bolzenkopf 54 das Werkzeug 23 aufgesetzt werden kann, das in diesem Falle ein Gabelschlüssel (Schraubenschlüssel) ist, der auf den sechseckigen Bolzenkopf 54 aufgesetzt wird, um den Gewindebolzen 52 zu verdrehen. Er wird mit dem Steckschlüssel 23 so gedreht, dass die beiden Hebelteile 41, 42 um die Achse des Bolzens 43 so geschwenkt werden, dass die Bogensegmente 1, 2 mit ihren Stirnseiten 4, 5 gegeneinander gedrückt werden. Der Verbinder 40 stützt sich mit den Bolzen 46, 47 in den Vertiefungen 48, 49 der Bogensegmente 1, 2 zuverlässig ab. Sobald das Klebemittel ausgehärtet ist, lässt sich der Verbinder 40 einfach abnehmen. Gegebenenfalls muss der Gewindebolzen 52 mit dem Werkzeug 23 geringfügig zurückgedreht werden, um den Verbinder 40 einfach abnehmen zu können.The threaded bolt 52 protrudes over the two lever parts 41, 42, so that the tool 23 can be placed on the bolt head 54, which in this case is an open-ended spanner (wrench) that is placed on the hexagonal bolt head 54 in order to move the threaded bolt 52 to twist. It is rotated with the socket wrench 23 in such a way that the two lever parts 41, 42 are pivoted about the axis of the bolt 43 in such a way that the end faces 4, 5 of the curved segments 1, 2 are pressed against one another become. The connector 40 is reliably supported with the bolts 46, 47 in the recesses 48, 49 of the arch segments 1, 2. Once the adhesive has cured, the connector 40 can be easily removed. If necessary, the threaded bolt 52 must be turned back slightly with the tool 23 in order to be able to easily remove the connector 40.

Die beiden Hebelteile 41, 42 haben ausreichenden Abstand von der gekrümmten Unterseite 12, so dass sie beim Pressvorgang ungehindert gegeneinander geschwenkt werden können. Auch der die Schwenkachse bildende Bolzen 43 befindet sich in ausreichendem Abstand zur Unterseite 12 und zur Außenseite 8.The two lever parts 41, 42 are at a sufficient distance from the curved underside 12 so that they can be pivoted against one another without hindrance during the pressing process. The bolt 43 forming the pivot axis is also located at a sufficient distance from the underside 12 and from the outside 8.

Die beiden Hebelteile 41, 42 können auch eine andere Form haben. Wesentlich ist nur, dass durch eine Schwenkbewegung zumindest des einen Hebelteiles eine Presskraft erzeugt wird.The two lever parts 41, 42 can also have a different shape. It is only essential that a pressing force is generated by a pivoting movement of at least one lever part.

Beim Ausführungsbeispiel nach den Fig. 7 und 8 wird als Verbinder 55 ein Getriebeverbinder eingesetzt. Er hat den Zugteil 18, der über eine Getriebeeinheit 56 um seine Längsachse gedreht werden kann. Mit dem Werkzeug 23 lässt sich die Getriebeeinheit 56 betätigen.In the embodiment according to the Figures 7 and 8 a gear connector is used as connector 55. It has the pulling part 18, which can be rotated about its longitudinal axis via a gear unit 56. The gear unit 56 can be actuated with the tool 23.

Das freie Ende des Zugteiles 18 ragt durch ein Abstützteil 57, das gekrümmt verläuft und so ausgebildet ist, dass es sich an die Wandung der Querbohrung 34 in dem Bogensegment 2 anlegen kann. Die Getriebeeinheit 56 liegt in der Querbohrung 34' des Bogensegmentes 1. Der Zugteil 18 greift in das Gewinde des Abstützteiles 57 ein.The free end of the pulling part 18 protrudes through a support part 57, which is curved and is designed so that it can rest against the wall of the transverse bore 34 in the arched segment 2. The gear unit 56 lies in the transverse bore 34 ′ of the arch segment 1. The tension part 18 engages in the thread of the support part 57.

Der Zugteil 18 liegt in miteinander fluchtenden Vertiefungen 58, 59 der Bogensegmente 1, 2. Die Vertiefungen 58, 59 sind zur Unterseite 12 der Bogensegmente sowie zu den Stirnseiten 4, 5 offen. Die Vertiefungen 58, 59 münden in die Querbohrungen 34, 34' der beiden Bogensegmente 1, 2. Dadurch kann der Verbinder 55 wie die Verbinder 16, 17 beim Ausführungsbeispiel gemäß den Fig. 3 und 4 von der Unterseite 12 aus eingesetzt werden. Der Durchmesser der Querbohrungen 34, 34' ist größer als die Querschnittsbreite der Vertiefungen 58, 59, so dass die Getriebeeinheit 56 und der Abstützteil 57 sich während des Pressvorganges zuverlässig abstützen können. Mit dem Werkzeug 23 wird die Getriebeeinheit 56 so gedreht, dass der Zugteil 18 in Fig. 7 in das Abstützteil 57 geschraubt wird. Über den Abstützteil 57 wird dadurch das Bogensegment 2 fest gegen das Bogensegment 1 gepresst. Sobald das Klebemittel in der Verbindungsstelle zwischen den beiden Bogensegmenten 1, 2 ausgehärtet ist, wird die Getriebeeinheit 56 mit dem Werkzeug 23 zurückgedreht, so dass der Zugteil 18 gelöst wird. Dann lässt sich der Verbinder 55 einfach abnehmen. Der Verbinder 55 kann aber auch im Rahmenteil verbleiben und ständig den Pressdruck auf die Bogensegmente 1, 2 ausüben.The pulling part 18 lies in recesses 58, 59 of the arc segments 1, 2 that are aligned with one another. The recesses 58, 59 are open to the underside 12 of the arc segments and to the end faces 4, 5. The depressions 58, 59 open into the transverse bores 34, 34 'of the two arc segments 1, 2. As a result, the connector 55, like the connectors 16, 17 in the exemplary embodiment according to the Figs. 3 and 4 can be used from the underside 12. The diameter of the transverse bores 34, 34 'is greater than the cross-sectional width of the depressions 58, 59, so that the gear unit 56 and the support part 57 can be reliably supported during the pressing process. With the tool 23, the gear unit 56 is rotated so that the pulling part 18 in Fig. 7 is screwed into the support part 57. As a result, the arch segment 2 is pressed firmly against the arch segment 1 via the support part 57. As soon as the adhesive has hardened in the connection point between the two arch segments 1, 2, the gear unit 56 is rotated back with the tool 23, so that the pulling part 18 is released. Then the connector 55 can easily be removed. The connector 55 can, however, also remain in the frame part and constantly exert the pressure on the arch segments 1, 2.

Der Verbinder 60 der Ausführungsform gemäß den Fig. 9 und 10 ist prinzipiell gleich ausgebildet wie der Verbinder 40 der Ausführungsform gemäß den Fig. 5 und 6. Der Verbinder 60 hat zwei Pressteile 61, 62, die spiegelbildlich zueinander angeordnet und durch einen Spannteil 63 miteinander verbunden sind. Die beiden Pressteile 61, 62 ragen in die Querbohrungen 34 der Bogensegmente 1, 2. Die mit Abstand von der Unterseite 12 der Bogensegmente 1, 2 liegenden Enden 64, 65 der Pressteile 61, 62 sind in Richtung zueinander abgewinkelt und mit jeweils einer Gewindebohrung versehen, in die der Spannteil 63 eingreift. Auf dem Spannteil 63 sitzt drehfest ein Mehrkantkopf 66, der mit dem Werkzeug 23 gedreht werden kann, das als Gabelschlüssel ausgebildet ist. Die beiderseits des Mehrkantkopfes 66 liegenden Teile des Spannteils 63 haben gegenläufiges Gewinde. Diese greifen in die Enden 64, 65 der Pressteile 61, 62 ein.The connector 60 of the embodiment according to FIGS Figures 9 and 10 is designed in principle the same as the connector 40 of the embodiment according to FIG Figures 5 and 6 . The connector 60 has two pressed parts 61, 62 which are arranged in mirror image to one another and are connected to one another by a clamping part 63. The two pressed parts 61, 62 protrude into the transverse bores 34 of the arch segments 1, 2. The ends 64, 65 of the pressed parts 61, 62 at a distance from the underside 12 of the arch segments 1, 2 are angled towards each other and each provided with a threaded hole , in which the clamping part 63 engages. A polygonal head 66 is non-rotatably seated on the clamping part 63 and can be rotated with the tool 23, which is designed as an open-ended wrench. The parts of the clamping part 63 lying on both sides of the polygonal head 66 have opposing threads. These engage in the ends 64, 65 of the pressed parts 61, 62.

Um die beiden Bogensegmente 1, 2 mit ihren Stirnseiten 4, 5 gegeneinander zu pressen, wird der Spannteil 63 über den Mehrkantkopf 66 mit dem Werkzeug 23 so gedreht, dass die Pressteile 61, 62 die Bogensegmente 1, 2 gegeneinander drücken. Die Pressteile 61, 62 legen sich mit ihren in die Querbohrungen 34 eingreifenden Enden so an die Bohrungswandung an, dass die Bogensegmente 1, 2 zuverlässig gegeneinander gepresst werden. Aufgrund der gegenläufig erfolgenden Bewegung können die Enden der Pressteile 61, 62 kleineren Querschnitt haben als die Querbohrungen 34. Die Pressteile 61, 62 legen sich an die Wandung der Querbohrungen 34 an, so dass die Bogensegmente 1, 2 fest gegeneinander gedrückt werden.In order to press the two curved segments 1, 2 with their end faces 4, 5 against one another, the clamping part 63 is rotated over the polygonal head 66 with the tool 23 in such a way that the pressed parts 61, 62 press the arched segments 1, 2 against one another. The pressed parts 61, 62 lay with their ends engaging in the transverse bores 34 against the wall of the bore, that the arc segments 1, 2 are reliably pressed against each other. Due to the opposing movement, the ends of the pressed parts 61, 62 can have a smaller cross-section than the transverse bores 34. The pressed parts 61, 62 lie against the wall of the transverse bores 34 so that the arch segments 1, 2 are pressed firmly against each other.

Die Pressteile 61, 62 ragen ausreichend weit aus den Querbohrungen 34, so dass der Spannteil 63 ausreichenden Abstand von der Unterseite 12 der Bogensegmente 1, 2 hat. Dadurch lässt sich der Spannteil 63 mit dem Werkzeug 23 einfach drehen.The pressed parts 61, 62 protrude sufficiently far from the transverse bores 34 so that the clamping part 63 has a sufficient distance from the underside 12 of the arch segments 1, 2. As a result, the clamping part 63 can easily be rotated with the tool 23.

Sobald das Klebemittel ausgehärtet ist, wird der Spannteil 63 zurückgedreht, so dass die Pressteile 61, 62 sich voneinander entfernen. Der Verbinder 60 lässt sich dann einfach von den Bogensegmenten 1, 2 abnehmen.As soon as the adhesive has hardened, the clamping part 63 is turned back so that the pressing parts 61, 62 move away from one another. The connector 60 can then be easily removed from the arch segments 1, 2.

Fig. 11 zeigt, dass die Bogensegmente 1, 2 im Bereich ihrer Stirnseiten mit einer Passfräsung 67, 68 versehen sein können. Sind an den Stirnseiten der Bogensegmente 1, 2 die Keilzinkenverzahnungen 6, 7 vorgesehen, dann sind die Passfräsungen 67, 68 zusätzlich vorgesehen. Im Ausführungsbeispiel wird die eine Passfräsung 67 durch eine über die Stirnseite 4 vorstehende Zunge gebildet, die in halber Breite der Bogensegmente vorgesehen ist und teilkreisförmigen Umriss hat. Die Zunge 67 steht vorteilhaft über die Keilzinkenverzahnung 7 über. Fig. 11 shows that the arc segments 1, 2 can be provided with a milled cut 67, 68 in the area of their end faces. If the finger-joint teeth 6, 7 are provided on the end faces of the arch segments 1, 2, then the milled-fit grooves 67, 68 are also provided. In the exemplary embodiment, the one fitting milled recess 67 is formed by a tongue projecting beyond the end face 4, which is provided at half the width of the arc segments and has a partially circular outline. The tongue 67 advantageously protrudes beyond the finger teeth 7.

An der anderen Stirnseite 5 der Bogensegmente 1, 2 ist die Passfräsung 68 durch eine der Zunge 67 entsprechende Vertiefung gebildet. Die Passfräsungen 67, 68 dienen als Radialpositionierhilfen beim Zusammenfügen der Bogensegmente 1, 2. Es ist dadurch einfach möglich, die miteinander zu verbindenden Bogensegmente so in Radialrichtung gegeneinander auszurichten, dass ihre Unterseiten 12 und Oberseiten 13 stufenlos aneinander schließen.On the other end face 5 of the arc segments 1, 2, the milled fit 68 is formed by a recess corresponding to the tongue 67. The milled-fit grooves 67, 68 serve as radial positioning aids when joining the arc segments 1, 2. It is thus easily possible to align the arc segments to be connected to one another in the radial direction so that their lower sides 12 and upper sides 13 close one another steplessly.

Die Passfräsung 67, 68 kann mit einem Werkzeug hergestellt werden, das auf einer vertikalen Spindel der Maschine sitzt. Mit solchen vertikalen Spindeln lassen sich sehr hohe Fertigungsgenauigkeiten erzielen, so dass die Passfräsung mit hoher Präzision erzeugt werden kann.The milled cut 67, 68 can be produced with a tool that sits on a vertical spindle of the machine. With such vertical spindles, very high manufacturing accuracies can be achieved, so that the milled fit can be produced with high precision.

Die Fig. 12 und 13 zeigen einen Verbinder 69, der dem Verbinder in Fig. 1 entspricht und im Wesentlichen gleich ausgebildet ist wie die Verbinder 16, 17 gemäß Fig. 2. Der einzige Unterschied zu dem Verbinder nach Fig. 2 besteht darin, dass der Zugteil 18 als Einschraubbolzen ausgebildet ist, der in die Stirnseite 5 des Bogensegmentes 1, 2 so geschraubt wird, dass das andere Ende 20 über die Stirnseite 5 vorsteht. In der gegenüberliegenden Stirnseite 4 befinden sich die Bohrungen 32, 33 (Fig. 1), in welche die Querbohrungen 34, 35 münden. Wie anhand von Fig. 1 beschrieben worden ist, nehmen die Querbohrungen 34, 35 die Exzenter 22 auf. Sie werden mittels des Werkzeuges 23 in der Querbohrung 34, 35 so gedreht, dass das verbreiterte Ende 20 des Zugteils 18 der Verbinder 16, 17 in die Nasen 26, 27 des Exzenters 22 eingehängt werden kann. Mit dem Werkzeug 23 wird der Exzenter 22 so gedreht, dass der eingehängte Zugteil 18 das Bogensegment 2 gegen das Bogensegment 1 drückt.The Figures 12 and 13 show a connector 69 similar to the connector in FIG Fig. 1 corresponds and is formed essentially the same as the connectors 16, 17 according to Fig. 2 . The only difference to the connector after Fig. 2 consists in the fact that the pulling part 18 is designed as a screw-in bolt which is screwed into the end face 5 of the arch segment 1, 2 in such a way that the other end 20 protrudes beyond the end face 5. The holes 32, 33 ( Fig. 1 ) into which the transverse bores 34, 35 open. As with Fig. 1 has been described, the transverse bores 34, 35 accommodate the eccentrics 22. They are rotated by means of the tool 23 in the transverse bore 34, 35 such that the widened end 20 of the pulling part 18 of the connectors 16, 17 can be hooked into the lugs 26, 27 of the eccentric 22. The eccentric 22 is rotated with the tool 23 in such a way that the suspended tension part 18 presses the arch segment 2 against the arch segment 1.

Fig. 14 zeigt die Möglichkeit, die Querbohrungen 34, 35 an der Oberseite 13 der Bogensegmente 1, 2 vorzusehen, wenn das Rahmenteil Bestand eines Fensterrahmens ist. Nach dem Einbau des Fensterrahmens sind die Querbohrungen durch das Mauerwerk verdeckt und darum nicht mehr sichtbar. Fig. 14 shows the possibility of providing the transverse bores 34, 35 on the upper side 13 of the arch segments 1, 2 if the frame part is part of a window frame. After installing the window frame, the cross holes are covered by the masonry and are therefore no longer visible.

Bei den verschiedenen Ausführungsbeispielen werden bogenförmige Segmente 1, 2 eingesetzt, mit denen vorzugsweise bogenförmige Fensterrahmen- und Fensterflügelteile hergestellt werden. Die eingesetzten Bogensegmente 1 bis 3 werden mit ihren Stirnseiten aufeinander gepresst. Die Verbindung der aneinander anschließenden Bogensegmente 1 bis 3 erfolgt durch ein Klebemittel, das auf zumindest eine Stirnseite der aneinander liegenden Bogensegmente 1 bis 3 aufgebracht wird. Die Verbinder dienen hierbei als Verleimpresse, die sicherstellt, dass die Bogensegmente 1 bis 3 mit hoher Presskraft gegeneinander gedrückt werden. Die Presskräfte sind sehr hoch und können über 1000 N liegen. In der Regel reicht ein Verbinder aus, um zwei Bogensegmente gegeneinander zu drücken. Sollte die Zugkraft des eingesetzten Verbinders nicht ausreichen und/oder die Zugkraft auf der Stirnfläche 4, 5 der Bogensegmente 1 bis 3 gleichmäßiger verteilt werden, können auch zwei oder mehr Verbinder pro Stirnfläche der Bogensegmente 1 bis 3 zum Einsatz kommen. Die Rundbögen können rational mit minimiertem Eingriff in der beschriebenen Weise gefertigt werden. Zur Verbindung der einzelnen Bogensegmente 1 bis 3 sind keine Dübel erforderlich, die aufgrund ungenügender Fertigungsgenauigkeiten den Nachteil haben, dass unbefriedigende Verleimgenauigkeiten und größere Toleranzen der zusammengesetzten Bogensegmente auftreten können. Solange das Klebemittel noch nicht abgebunden hat, kann die Verbindung noch gelöst werden, indem die Verbinder so zurückgestellt werden, dass die Rundbogensegmente 1 bis 3 voneinander gelöst werden können. Sind die Verbinder innerhalb der Rundbogensegmente 1 bis 3 untergebracht (Fig. 1, 3, 4, 7, 8 und 11 bis 13), dann ist zur dauerhaften festen Verbindung der Bogensegmente 1 bis 3 ein Klebemittel nicht unbedingt erforderlich.In the various exemplary embodiments, arcuate segments 1, 2 are used, with which arcuate window frame and window sash parts are preferably produced. The curved segments 1 to 3 used are pressed onto one another with their end faces. The connection of the adjoining arc segments 1 to 3 takes place by means of an adhesive which is applied to at least one end face of the arc segments 1 to 3 lying next to one another. The connectors serve as a gluing press, which ensures that the curved segments 1 to 3 are pressed against each other with high pressing force. The pressing forces are very high and can be over 1000 N. Usually one connector is sufficient to press two arch segments against each other. If the tensile force of the connector used is insufficient and / or the tensile force on the end face 4, 5 of the arc segments 1 to 3 is more evenly distributed, two or more connectors per end face of the arc segments 1 to 3 can also be used. The round arches can be manufactured rationally with minimal intervention in the manner described. To connect the individual arch segments 1 to 3, no dowels are required which, due to insufficient manufacturing accuracy, have the disadvantage that unsatisfactory gluing accuracy and greater tolerances of the assembled arch segments can occur. As long as the adhesive has not yet set, the connection can still be released by repositioning the connectors in such a way that the arched segments 1 to 3 can be detached from one another. Are the connectors housed within the arch segments 1 to 3 ( Fig. 1 , 3 , 4th , 7th , 8th and 11 to 13 ), then an adhesive is not absolutely necessary for a permanent, fixed connection of the arch segments 1 to 3.

Die Rundbogensegmente 1 bis 3 können an der Baustelle zum Rundbogen zusammengesetzt werden, wodurch der Transport erheblich vereinfacht wird, da keine fertigen Rundbögen transportiert werden müssen. Zum Verbinden der Bogensegmente 1 bis 3 sind keine Sondervorrichtungen auf Rahmenpressen erforderlich. Die Verbinder selbst bilden die Verleimpressen, mit denen die einzelnen Bogensegmente einzeln nacheinander miteinander verbunden werden können. Dadurch wird die Rahmenpresse, wie sie zum Verpressen von rechteckigen Standardfensterrahmen benötigt wird, nicht blockiert.The round arch segments 1 to 3 can be put together to form a round arch at the construction site, which considerably simplifies transport since no finished round arches have to be transported. No special devices on frame presses are required to connect the arch segments 1 to 3. The connectors themselves form the glue presses with which the individual arch segments can be connected to one another one after the other. As a result, the frame press, as it is required for pressing rectangular standard window frames, is not blocked.

Die Querbohrungen 34, 35 bzw. die Vertiefungen 38, 39; 48, 49; 58, 59 beeinflussen das Rundbogenfenster funktionell oder optisch nicht. Diese Querbohrungen bzw. Vertiefungen sitzen bei einem Flügel beispielsweise im Glasfalz und sind nach der Montage des Fensterglases unsichtbar. Werden die Bogensegmente für einen Fensterrahmen verwendet, befinden sich die Querbohrungen bzw. Vertiefungen außen und sind nach dem Einbau des Fensterrahmens im Mauerwerk nicht mehr sichtbar. Es ist auch möglich, die Verbinder oder die Bohrungen für die Verbinder nach dem Verbinden der Bogensegmente durch Abdeckungen, wie zum Beispiel Stopfen, Abdecckappen oder Ähnliches, zu verschließen.The transverse bores 34, 35 or the depressions 38, 39; 48, 49; 58, 59 do not affect the arched window functionally or optically. In the case of a sash, for example, these cross bores or depressions are located in the glass rebate and are invisible after the window glass has been installed. Become If the arch segments are used for a window frame, the cross bores or depressions are on the outside and are no longer visible in the masonry after the window frame has been installed. It is also possible to close the connectors or the bores for the connectors after connecting the arch segments by means of covers, such as stoppers, caps or the like.

Die Verbinder können bei einem Rahmenteil für einen Fensterflügel (Fig. 1) nicht nur an der Unterseite 12, sondern auch an einer der drei anderen Seiten 13, 8, 9 vorgesehen sein. Wird das Rahmenteil für einen Fensterrahmen eingesetzt (Fig. 14), dann kann der Verbinder auch an einer der anderen drei Seiten vorgesehen sein. Werden zwei oder mehr Verbinder eingesetzt, können diese in verschiedenen Seiten der Bogensegmente vorgesehen sein.In the case of a frame part for a window sash ( Fig. 1 ) not only be provided on the underside 12, but also on one of the three other sides 13, 8, 9. If the frame part is used for a window frame ( Fig. 14 ), then the connector can also be provided on one of the other three sides. If two or more connectors are used, they can be provided in different sides of the arch segments.

Die beschriebenen Vorteile gelten in gleicher Weise auch für das Längskoppeln von geraden Segmenten, die auf die gleiche Weise fest miteinander stirnseitig verbunden werden können.The advantages described also apply in the same way to the longitudinal coupling of straight segments which can be firmly connected to one another at the end in the same way.

Die einzelnen Segmente können nacheinander in der beschriebenen Weise miteinander verbunden werden. Werden in die Segmente 1 bis 3 integrierte Verbinder eingesetzt, dann können die Segmente 1 bis 3 nacheinander verbunden werden, ohne dass, sofern Klebemittel verwendet wird, abgewartet werden muss, bis das Klebemittel abgebunden hat. Bei als Verleimpressen wirkenden Verbindern können die Segmente ebenso nacheinander verbunden werden, ohne dass abgewartet werden muss, bis das Klebemittel abgebunden hat. Allerdings dürfen die Verbinder erst nach dem Abbinden des Klebemittels bzw. Leims gelöst und entfernt werden.The individual segments can be connected to one another one after the other in the manner described. If integrated connectors are used in segments 1 to 3, segments 1 to 3 can be connected one after the other without having to wait until the adhesive has set, if adhesive is used. In the case of connectors acting as glue presses, the segments can also be connected one after the other without having to wait for the adhesive to set. However, the connectors may only be loosened and removed after the adhesive or glue has set.

Die Werkzeuge 23 können auch angetriebene Werkzeuge sein, wie Ackuschrauber, pneumatisch oder hydraulisch oder elektrisch angetriebene Werkzeuge. Die Verbinder, die nach dem Verpressen abgenommen werden können, können einen integrierten Antrieb enthalten, beispielsweise in Form eines Pneumatik-, eines Hydraulik- oder eines Elektroantriebes. Auch ein mechanischer Antrieb, der beispielsweise mittels eines Federantriebes arbeitet, kann in die Verbinder integriert sein.The tools 23 can also be driven tools, such as screwdrivers, pneumatically or hydraulically or electrically driven tools. The connectors, which can be removed after pressing, can contain an integrated drive, for example in form a pneumatic, hydraulic or electric drive. A mechanical drive, which works for example by means of a spring drive, can also be integrated into the connector.

Mit den Bogensegmenten 1 bis 3 können je nach ihrer Ausbildung unterschiedlichste Formen von Rundbogenfenstern hergestellt werden. Die einzelnen Segmente werden jeweils auf die gleiche Art und Weise miteinander verbunden, wie anhand der Ausführungsbeispiele erläutert worden ist.With the arch segments 1 to 3, depending on their design, a wide variety of shapes of arched windows can be produced. The individual segments are each connected to one another in the same way as has been explained with reference to the exemplary embodiments.
