STAND DER TECHNIKSTATE OF THE ART

Bei den bekannten Schalzwingen der eingangs genannten Art verläuft die Gewindespindel ober- oder unterhalb des Zwingenträgers. Dadurch kommt es häufig zu Verschmutzungen der Gewindespindel, beispielsweise durch angebackenes Betonmaterial, die eine dauerhaft zuverlässige Funktion beeinträchtigen. Das Entfernen derartiger Verschmutzungen ist aufwändig und zeitraubend. Dadurch, dass die Gewindespindel mehr oder weniger frei zugänglich ist, besteht die Gefahr, dass die Spindel infolge des rauen Baustellenbetriebes beschädigt wird und daher die Schalzwinge nicht mehr eingesetzt werden kann.In the known scarf clamps of the type mentioned above, the threaded spindle extends above or below the clamp carrier. This often leads to contamination of the threaded spindle, for example, by baked concrete material that affect a permanently reliable function. The removal of such contamination is complex and time consuming. The fact that the threaded spindle is more or less freely accessible, there is a risk that the spindle due to the rough Construction site operation is damaged and therefore the scarf clamp can not be used.

In der US 3,520,527 A als nächstliegender Stand der Technik ist eine Zwingeneinrichtung mit den eingangs genannten Merkmalen beschrieben. Diese Zwingeneinrichtung besitzt einen festen Schenkel und einen längsverschieblichen zweiten Schenkel, an dem ein Formschlusselement gelagert ist, das in dem Außengewinde der Gewindespindel kämmt. An dem zweiten Schenkel ist ein federbeaufschlagter Gelenkmechanismus vorhanden, mittels dem das Formschlusselement mit dem Gewinde der Gewindespindel außer Eingriff gebracht werden kann, so dass der zweite Schenkel ohne Drehung der Gewindespindel in Längsrichtung verschoben werden kann. Dadurch ergibt sich eine aufwendige Konstruktion mit vielen Einzelteilen.In the US 3,520,527 A As a closest prior art, a clamp device is described with the features mentioned. This clamp device has a fixed leg and a longitudinally displaceable second leg, on which a positive locking element is mounted, which meshes in the external thread of the threaded spindle. On the second leg, a spring-loaded hinge mechanism is provided by means of which the positive-locking element can be brought out of engagement with the thread of the threaded spindle, so that the second leg can be displaced in the longitudinal direction without rotation of the threaded spindle. This results in a complex construction with many items.

In der DE 44 43 333 A1 ist eine Schalungszwinge beschrieben, bei der beide Schenkel über querschnittskonforme Hülsen linear verschieblich auf einem Querjoch geführt sind, wobei eine Stellspindel für den die Feineinstellungen beziehungsweise den Schließdruck erzeugenden Schenkel stirnseitig am zugehörigen Ende des Querjochs angeordnet ist.In the DE 44 43 333 A1 is a formwork clamp described in which both legs are guided linearly displaceable on cross-section sleeves on a transverse yoke, wherein an adjusting spindle for the fine adjustments or the closing pressure generating leg is arranged frontally at the associated end of the transverse yoke.

WEGE ZUM AUSFÜHREN DER ERFINDUNGWAYS FOR CARRYING OUT THE INVENTION

Das in den Figuren dargestellte Ausführungsbeispiel einer Zwingeneinrichtung 10 wird bevorzugt zum Erstellen von Unterstützungskonstruktionen für Schalungen beim Betonieren von Bauwerken eingesetzt.The exemplary embodiment of a clamp device 10 shown in the figures is preferably used for constructing support structures for formworks when concreting structures.

Die Zwingeneinrichtung 10 weist einen Zwingenträger 12 auf, der als U-Profil ausgebildet ist. Innerhalb des U-Profilquerschnitts des Zwingenträgers 12 ist eine Gewindespindel 14 angeordnet. In den Figuren ist die Gewindespindel 14 lediglich als Rundprofil ohne Darstellung ihres Außengewindes gezeichnet.The clamp device 10 has a clamp carrier 12, which is designed as a U-profile. Within the U-profile cross section of the clamp carrier 12, a threaded spindle 14 is arranged. In the figures, the threaded spindle 14 is drawn only as a round profile without representation of its external thread.

In dem in Figur 1 rechten Endbereich des Zwingenträgers 12 ist eine Querscheibe 50 angeschweißt, die eine Ausnehmung aufweist, innerhalb derer die Gewindespindel 14 drehbar gelagert ist. In dem in Figur 1 rechten Endbereich der aus dem Zwingenträger 12 herausragenden Gewindespindel 14 ist eine Handkurbel 16 an die Gewindespindel 14 angeschlossen, mittels derer die Gewindespindel 14 in Drehung versetzt werden kann.In the in FIG. 1 right end portion of the clamp support 12 is a transverse plate 50 welded, which has a recess, within which the threaded spindle 14 is rotatably mounted. In the in FIG. 1 right end portion of protruding from the ferrule 12 threaded spindle 14 is a hand crank 16 connected to the threaded spindle 14, by means of which the threaded spindle 14 can be set in rotation.

Die Zwingeneinrichtung 10 weist einen ersten Schenkel 20 und einen zweiten Schenkel 22 auf. Beide Schenkel 20, 22 sind über ein erstes Anschlussprofilelement 26 beziehungsweise ein zweites Anschlussprofilelement 28 an den Zwingenträger 12 angeschlossen. Beide Anschlussprofilelemente 26, 28 sind dabei als Rechteckhohlprofilelemente ausgebildet, die den U-Profilquerschnitt des Zwingenträgers 12 umschließen, wobei die lichten Innenabmessungen der Anschlussprofilelemente 26, 28 geringfügig größer ausgebildet sind als die lichten Außenabmessungen des Zwingenträgers 12.The clamp device 10 has a first leg 20 and a second leg 22. Both legs 20, 22 are connected via a first connection profile element 26 and a second connection profile element 28 to the clamp carrier 12. Both connection profile elements 26, 28 are formed as rectangular hollow profile elements which enclose the U-profile cross section of the clamp carrier 12, wherein the clear inner dimensions of the connection profile elements 26, 28 are formed slightly larger than the clear outer dimensions of the clamp carrier 12th

Der der Handkurbel 16 nächststehende erste Schenkel 20 ist während des Spannvorgangs als fester Schenkel ausgebildet. Die Fixierung des ersten Schenkels 20 am Zwingenträger 12 erfolgt über einen Fixierstift 34, der einen Hakenbereich 46 und einen Stielbereich 48 aufweist. Der Stielbereich 48 ist in einer an dem ersten Anschlussprofilelement 26 angeschlossenen Haltehülse 38 längsverschieblich (Pfeil Z in Figur 4) gelagert. Der Hakenbereich 46 des Fixierstiftes 34 wird zum Fixieren des ersten Schenkels 20 durch eine oberseitig an dem ersten Anschlussprofilelement 26 vorhandene Ausnehmung 52 geführt, die mit einer jeweiligen am oberen Steg des U-Profils des Zwingenträgers 12 rastermäßig vorhandenen Rasterausnehmung 32 zur Deckung gebracht wird, wobei der Hakenbereich 46 des Fixierstiftes 34 zum Fixieren in eine jeweilige Rasterausnehmung 32 des Zwingenträgers 12 formschlüssig eingeführt wird.The hand crank 16 nearest first leg 20 is formed during the clamping process as a fixed leg. The fixation of the first leg 20 on the ferrule carrier 12 via a fixing pin 34 which has a hook portion 46 and a handle portion 48. The stem region 48 is longitudinally displaceable in a holding sleeve 38 connected to the first connection profile element 26 (arrow Z in FIG FIG. 4 ) stored. The hook area 46 of the fixing pin 34 is guided for fixing the first leg 20 by a recess 52 provided on the top side of the first connection profile element 26, which is brought into coincidence with a respective grid recess 32 arranged in a grid pattern on the upper web of the U-profile of the clamp support 12, wherein the hook portion 46 of the fixing pin 34 is inserted positively for fixing in a respective grid recess 32 of the clamp carrier 12.

Im unteren Endbereich des Stielbereiches 48 des Fixierstiftes 34 ist quer zur Längsachse ein Spannstift 44 angeordnet. Zwischen Spannstift 44 und Unterseite der Haltehülse 38 ist ein Federelement 36 angeordnet, das auf den Fixierstift 34 eine Kraft entgegen der Pfeilrichtung Z, das heißt in Formschlussrichtung mit der Rasterausnehmung 32 ausübt. Der obere Hakenbereich 46 des Fixierstiftes 34 wird von einem Ziehring 42 untergriffen, der ein einfaches Lösen des fixierten ersten Schenkels 20 erlaubt, indem in einfacher Art und Weise der Ziehring 42 in Pfeilrichtung Z nach oben gezogen wird. Mit dieser Ausgestaltung ist eine Schnellverstellung des "festen" Schenkels 20 problemlos möglich, was insgesamt zu kürzeren Montagezeiten führt.In the lower end region of the stem region 48 of the fixing pin 34, a clamping pin 44 is arranged transversely to the longitudinal axis. Between the clamping pin 44 and underside of the holding sleeve 38, a spring element 36 is arranged, which exerts on the fixing pin 34 a force against the direction of the arrow Z, that is in the form-locking direction with the grid recess 32. The upper hook portion 46 of the fixing pin 34 is engaged by a drawing ring 42, which allows a simple release of the fixed first leg 20 by pulling in a simple manner, the drawing ring 42 in the direction of arrow Z upwards. With this configuration, a quick adjustment of the "fixed" leg 20 is easily possible, resulting in a total of shorter assembly times.

Sowohl das erste Anschlussprofilelement 26 als auch das zweite Anschlussprofilelement 28 weisen zur Längsrichtung des Zwingenträgers 12 geneigte Stirnseitenkanten 40 auf, sodass in einer Seitenansicht gesehen die Anschlussprofilelemente 26, 28 eine parallelogrammartige Umfangskontur aufweisen. Dadurch ergeben sich bessere Hebelverhältnisse beim Spannen bei gleichzeitig optimaler Materialausnutzung. Weiterhin ergibt sich eine größere Führungslänge auf dem Zwingenträger 12 beim Bewegen der Schenkel 20, 22, was eine dauerhafte zuverlässige Funktion gewährleistet.Both the first connection profile element 26 and the second connection profile element 28 have 12 inclined end side edges 40 to the longitudinal direction of the clamp carrier, so seen in a side view, the connection profile elements 26, 28 have a parallelogram-like circumferential contour. This results in better leverage during clamping while optimally utilizing the material. Furthermore, there is a greater guide length on the ferrule carrier 12 when moving the legs 20, 22, which ensures a durable reliable function.

Der zweite Schenkel 22 ist längsverschieblich am Zwingenträger 12 gelagert. Die Verschiebung des zweiten Schenkels 22 wird durch Drehung der Handkurbel 16 und damit der Gewindespindel 14 bewirkt. Konstruktiv wird dies dadurch umgesetzt, dass in einer parallel zur offenen Seite des Zwingenträgers 12 in der Wandung des zweiten Anschlussprofilelements 28 eine rechteckförmige Ausnehmung 30 vorhanden ist, in die ein Innengewindeelement 24 im Querschnitt formschlüssig eingeschoben ist, das in das Innere des U-Profils des Zwingenträgers 12 ragt und in diesem Bereich ein Innengewinde 25 aufweist, in dem die Gewindespindel 14 kämmt. Durch die Lagerung in der Ausnehmung 30 ist das Innengewindeelement 24 gegen Verdrehung und Längsverschiebung gesichert.The second leg 22 is mounted longitudinally displaceable on the ferrule carrier 12. The displacement of the second leg 22 is effected by rotation of the hand crank 16 and thus the threaded spindle 14. This is implemented in a constructive manner in that in a parallel to the open side of the clamp carrier 12 in the wall of the second connection profile element 28, a rectangular recess 30 is provided, into which a female thread member 24 is inserted positively in cross-section, in the interior of the U-profile of Zwingenträgers 12 protrudes and in this area has an internal thread 25 in which the threaded spindle 14 meshes. Due to the bearing in the recess 30, the internal thread member 24 is secured against rotation and longitudinal displacement.

Bei der Herstellung der Zwingeneinrichtung 10 wird zunächst das erste Anschlussprofilelement 26 mit dem ersten Schenkel 20 auf den Zwingenträger 12 aufgeschoben. Daran anschließend wird das zweite Anschlussprofilelement 28 mit dem zweiten Schenkel 22 ebenfalls auf den Zwingenträger 12 aufgeschoben. Sodann wird von außen das Innengewindeelement 24 über die Ausnehmung 30 eingeschoben, wobei das Innengewindeelement 24 im eingeschobenen Zustand formschlüssig gegen Verdrehung in der Ausnehmung 30 gehalten ist. Daran anschließend wird die Gewindespindel 14 eingeführt und in das Innengewinde 25 des Innengewindeelements 24 eingeschraubt. Dadurch ist die Gewindespindel 14 innerhalb des Querschnitts des Zwingenträgers 12 in ihrer Querschnittslage fixiert.In the production of the clamp device 10, first the first connection profile element 26 with the first leg 20 is pushed onto the clamp carrier 12. Subsequently, the second connection profile element 28 with the second leg 22 is likewise pushed onto the ferrule carrier 12. Then, the female thread member 24 is inserted from the outside via the recess 30, wherein the female thread member 24 is held in the inserted state positively against rotation in the recess 30. Subsequently, the threaded spindle 14 is inserted and screwed into the internal thread 25 of the female thread member 24. As a result, the threaded spindle 14 is fixed within the cross section of the clamp carrier 12 in its cross-sectional position.

Durch einfaches Drehen der Handkurbel 16 wird der zweite Schenkel 22 im Einsatzfall in die entsprechende Position verschoben.By simply turning the hand crank 16, the second leg 22 is moved in the application in the appropriate position.

Wie in Figur 5 zu erkennen, ist im vorliegenden Ausführungsbeispiel das Innengewindeelement 24 als Vierkantmutter ausgebildet. Die Breite B des Innengewindeelements 24 ist dabei so bemessen, dass bei der Montage der Zwingeneinrichtung 10 nach dem Einführen des Innengewindeelements 24 in die Ausnehmung 30 des zweiten Anschlussprofilelements 28 dieses nicht in das Innere des U-Profils des Zwingenträgers 12 fallen kann, in dem es zuvor zur Anlage mit der Innenwandung des Stegs des U-Profils des Zwingenträgers 12 kommt. Die Höhe H des Innengewindeelements 24 ist daher geringfügig kleiner als die Höhe der rechteckförmigen Ausnehmung 30. Zusätzliche Befestigungsmaßnahmen des Innengewindeelements 24 sind nicht erforderlich. Nach dem Einschrauben der Gewindespindel 14 in das Innengewinde 25 des Innengewindeelements 24 ist eine eindeutige Lagefixierung der einzelnen Bauteile hinsichtlich einer dauerhaft zuverlässigen Funktion gewährleistet.As in FIG. 5 to recognize, in the present embodiment, the internal thread member 24 is formed as a square nut. The width B of the internal thread member 24 is dimensioned so that when installing the ferrule device 10 after insertion of the female thread member 24 into the recess 30 of the second terminal profile element 28 this can not fall into the interior of the U-profile of the clamp carrier 12 in which it previously comes to rest with the inner wall of the web of the U-profile of the clamp carrier 12. The height H of the female thread member 24 is therefore slightly smaller than the height of the rectangular recess 30. Additional attachment measures of the female thread member 24 are not required. After screwing the threaded spindle 14 into the internal thread 25 of the internal thread member 24 a clear positional fixation of the individual components is ensured in terms of a permanently reliable function.

In Figur 6 ist im Querschnitt eine Schalzwinge 10.1 dargestellt, die im Wesentlichen den gleichen Aufbau aufweist wie die Schalzwinge 10 gemäß Figur 5. Ein Unterschied besteht darin, dass als Zwingenträger 12.1 ein C-Profil eingesetzt wird, das nach innen weisende Umkantungen 54 aufweist, wobei der Abstand der Stirnendseiten der Umkantungen 54 geringfügig größer ist als die Höhe H des Innengewindeelements 24.In FIG. 6 is a shell clamp 10.1 shown in cross-section, which has substantially the same structure as the shutter clamp 10 according to FIG. 5 , One difference is that a C-profile is used as a clamp support 12.1, which has inwardly facing curbs 54, wherein the distance of the front end sides of the folded edges 54 is slightly greater than the height H of the female thread member 24th

Die Schnittdarstellung gemäß Figur 7 zeigt eine Schalzwinge 10.2 entsprechend dem Aufbau gemäß der Schalzwinge 10.1 von Figur 6. Jedoch wird bei der Schalzwinge 10.2 ein Innengewindeelement 24.1 eingesetzt, das eine Sechseckumfangskontur aufweist. Auch dieses Innengewindeelement 24.1 ist in der Ausnehmung 30 formschlüssig gegen Verdrehung und Längsverschiebung gelagert und weist eine Breite B auf, die verhindert, dass das Innengewindeelement 24.1 in das Innere des Zwingenträgers 12.2 fallen kann.The sectional view according to FIG. 7 shows a scarf clamp 10.2 according to the structure according to the scarf clamp 10.1 of FIG. 6 , However, in the scarf clamp 10.2 Inserted internal thread element 24.1, which has a hexagonal peripheral contour. Also, this internal thread member 24.1 is positively mounted in the recess 30 against rotation and longitudinal displacement and has a width B, which prevents the internal thread member 24.1 can fall into the interior of the clamp support 12.2.

Beim Herstellen der Schalzwinge 10.2 kann das Innengewindeelement 24.1 nicht von außen her durch die Ausnehmung 30 hindurch eingeführt werden. Vielmehr wird das Innengewindeelement 24.1 manuell seitlich in das zweite Anschlussprofilelement 28 eingeschoben, bis es sich auf Höhe der Ausnehmung 30 befindet, und dann quer zur Ausnehmung 30 ausgerichtet. Daran anschließend wird der Zwingenträger 12.2 in das zweite Anschlussprofilelement 28 eingeschoben bis er mit dem Innengewindeelement 24.1 zum Anschlag kommt. Dann wird das Innengewindeelement 24.1 in Richtung der Ausnehmung 30 manuell verschoben, sodass daran anschließend der Zwingenträger 12.2 weiter durch das zweite Anschlussprofilelement 28 hindurchgeschoben werden kann. Diese Position ist in Figur 7 dargestellt. Das Innengewindeelement 24.1 mit Sechseckumfangskontur greift bereichsweise in die Ausnehmung 30 ein, sodass es gegen Verdrehung und Längsverschiebung gesichert ist. Sobald die Gewindespindel 14 in das Innengewinde 25 des Innengewindeelements 24 eingedreht ist, ist eine Relativverschiebung zwischen Zwingenträger 12.2 und zweitem Anschlussprofilelement 28 möglich.When manufacturing the clamp 10.2, the internal thread member 24.1 can not be introduced from the outside through the recess 30 therethrough. Rather, the internal thread member 24.1 is manually inserted laterally into the second connection profile element 28 until it is at the height of the recess 30, and then aligned transversely to the recess 30. Subsequently, the ferrule carrier 12.2 is inserted into the second connection profile element 28 until it comes to the stop with the internal thread element 24.1. Then, the internal thread element 24.1 is manually displaced in the direction of the recess 30, so that subsequently the ferrule carrier 12.2 can be pushed further through the second connection profile element 28. This position is in FIG. 7 shown. The internal thread element 24.1 with hexagonal peripheral contour engages partially in the recess 30, so that it is secured against rotation and longitudinal displacement. Once the threaded spindle 14 is screwed into the internal thread 25 of the female thread member 24, a relative displacement between ferrule 12.2 and second terminal profile element 28 is possible.
