Description

Die Erfindung betrifft eine Säulenschalung mit Schaltafeln, die jeweils an der Stirnseite einer über Eck benachbarten Schaltafel vorbeigeschalt sind, wobei eine zur Veränderung des Säulenquerschnittes verstellbare Verbindungskupplung jeweils an der einen Schaltafel im vorbeigeschalten Bereich und an der anderen Schaltafel auf deren Außenseite angreift und diese Verbindungskupplung dabei einerseits an Aussteifungsstegen od.dgl. der Außenseite der Schaltafeln nahe ihrer Stirnseite angreift und andererseits mit Hilfe eines parallel zu dieser Schaltafel verlaufenden, quer zu der vorbeigeschalten Schaltafel orientierten, mittelbar oder unmittelbar an der vorbeigeschalten Schaltafel verankerbaren Befestigungsbolzens in der jeweiligen Position festlegbar ist, wobei der Befestigungsbolzen einen Langschlitz od.dgl. an der Verbindungskupplung quer zur Orientierung dieses Langschlitzes durchsetzt und auf der der vorbeigeschalten Schaltafel abliegenden Seite mit Hilfe eines Widerlagers übergreift, welches durch eine Verankerung des Befestigungsbolzens vorzugsweise mittels einer Mutter od. dgl. gegen die Verbindungskupplung zur Anlage bringbar ist.The invention relates to a column formwork with formwork panels, each of which is connected to the front of a formwork panel adjacent to a corner, a connection coupling that can be adjusted to change the column cross-section engages on the outside of one formwork panel and the other formwork panel on the outside thereof, and this connection coupling on the one hand on stiffening webs or the like. engages the outside of the formwork panels near its end face and, on the other hand, can be fixed in the respective position with the aid of a fastening bolt that runs parallel to this formwork panel and is oriented transversely to the formwork panel that is anchored, directly or indirectly or directly anchored to the formwork panel, whereby the fastening bolt has an elongated slot or the like . interspersed on the connection coupling transversely to the orientation of this elongated slot and overlaps on the side remote from the switching panel by means of an abutment, which can be brought to bear against the connection coupling by anchoring the fastening bolt preferably by means of a nut or the like.

Eine derartige Säulenschalung ist aus der GB-PS 907 377 bekannt. Als Verbindungskupplung sind dabei zwei parallele vorzugsweise zu Winkelprofilen ausgesteifte Flacheisen vorgesehen, die etwa parallel zueinander mit Abstand zweier einander zugewandter Flachseiten angeordnet sind. Dieser Abstand zwischen den Flacheisen bildet einen Langschlitz, der von einem Verbindungsbolzen durchsetzt ist. Dieser Verbindungsbolzen ist einerseits in einer Verlängerung der vorbeigeschalten Schaltafel verankert, während er andererseits die der vorbeigeschalten Schalung abliegende Seite des Langschlitzes mit einem überstehenden Widerlager übergreift. Dieser Verbindungsbolzen kann dabei mit Hilfe einer dem Widerlager gegenüberliegenden Mutter an einem Gewinde verspannt werden.Such column formwork is known from GB-PS 907 377. Two parallel flat bars, preferably stiffened to form angle profiles, are provided as the connecting coupling, which are arranged approximately parallel to one another at a distance from two flat sides facing one another. This distance between the flat bars forms a long slot, which is penetrated by a connecting bolt. This connecting bolt is anchored on the one hand in an extension of the formwork panel which has passed, while on the other hand it overlaps the side of the elongated slot which is located away from the formwork with a protruding abutment. This connecting bolt can be clamped to a thread using a nut opposite the abutment.

Die eigentliche Festlegung des Verbindungsbolzens in seiner jeweiligen Position erfolgt mit Hilfe wenigstens eines ihn gegenüber den auftretenden Kräften hintergreifenden Keiles. Zu diesem Zweck haben die als Verbindungskupplung dienenden Flacheisen eine Vielzahl von in ihrer Orientierungsrichtung verlaufenden Langschlitzen, die in Reihen nebeneinanderliegen und gegeneinander versetzt sind, so daß je nach Lage des Befestigungsbolzens ein entsprechender Einsteckschlitz für den Keil gewählt werden kann. Aufgrund der Keilwirkung ist so eine stufenlose Anpassung an unterschiedliche Abmessungen im Rahmen der Länge der Verbindungskupplung und der Ausdehnung des mit solchen Keil-Schlitzen versehenen Feldes möglich. Nachteilig ist jedoch, daß die Verbindungskupplung aufgrund der beiden getrennt verlaufenden Flacheisen fest an der einen Schaltafel angebracht sein muß. Ferner ist die Verankerung des Verbindungsbolzens aufwendig, weil er nicht nur mit Hilfe einer Spannmutter gegenüber der Verbindungskupplung verspannt, sondern zusätzlich mit Hilfe eines weiteren Teiles, nämlich eines Keiles, abgestützt werden muß. Dabei ist nicht nur dieses zusätzliche Verankerungsteil und die Notwendigkeit seiner Montage eine zusätzliche Schwierigkeit, sondern es besteht auch die Gefahr, daß bei der Vielzahl von Keil-Schlitzen der falsche Schlitz gewählt werden könnte, so daß der Keil zu locker oder zu wenig tief sitzt und somit die Verankerung der Kupplung ungenügend ist.The actual fixing of the connecting bolt in its respective position takes place with the help of at least one wedge engaging behind it with respect to the forces that occur. For this purpose, the flat bars serving as a connecting coupling have a large number of elongated slots which run in their orientation direction and which are adjacent to one another in rows and offset from one another, so that a corresponding insertion slot for the wedge can be selected depending on the position of the fastening bolt. Because of the wedge effect, a continuous adjustment to different dimensions is possible within the scope of the length of the connecting coupling and the expansion of the field provided with such wedge slots. The disadvantage, however, is that the connection coupling must be firmly attached to one formwork panel due to the two separate flat irons. Furthermore, the anchoring of the connecting bolt is complex because it not only has to be braced with respect to the connecting coupling with the aid of a clamping nut, but also has to be supported with the aid of another part, namely a wedge. Not only is this additional anchoring part and the necessity of its assembly an additional difficulty, but there is also the risk that the wrong slot could be chosen in the case of the large number of wedge slots, so that the wedge sits too loosely or too little and thus the anchorage of the coupling is insufficient.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Säulenschalung der eingangs erwähnten Art mit einer Verbindungskupplung zu schaffen, bei welcher für deren sichere und kraftschlüssige Verbindung das Verankern des Befestigungsbolzens in der der jeweiligen Abmessung entsprechenden Lage ausreicht, um eine sichere Verbindung der über Eck benachbarten Schaltafeln zu erreichen.The invention is therefore based on the object of providing a column formwork of the type mentioned at the outset with a connecting coupling in which, for its secure and non-positive connection, the anchoring of the fastening bolt in the position corresponding to the respective dimension is sufficient to ensure a secure connection of the formwork panels adjacent around the corner to reach.

Die Lösung dieser Aufgabe besteht im wesentlichen darin, daß wenigstens ein von dem Widerlager des Befestigungsbolzens beaufschlagter Rand des Langschlitzes mit in seiner Orientierungsrichtung nebeneinanderliegenden Raststellen oder Vertiefungen versehen ist, in welche das Widerlager wenigstens teilweise formschlüssig eingreift. Auf diese Weise genügt es, den Befestigungsbolzen mit seinem Widerlager an einer der jeweiligen Abmessung der Säulenschalung entsprechenden Stelle formschlüssig am Rand des Langschlitzes anzusetzen und beispielsweise mit Hilfe einer Mutter od.dgl. an dem entgegengesetzten Ende zu verspannen. Dadurch ist der Befestigungsbolzen bereits in allen Richtungen formschlüssig festgelegt und kann entsprechende Kräfte ohne die zusätzliche Verwendung von Stützkeilen od.dgl. aufnehmen. Entsprechend einfach ist die Montage.The solution to this problem consists essentially in the fact that at least one edge of the elongated slot acted upon by the abutment of the fastening bolt is provided with latching points or depressions lying next to one another in its orientation direction, into which the abutment engages at least partially in a form-fitting manner. In this way, it is sufficient to positively attach the fastening bolt with its abutment at a location corresponding to the respective dimension of the column formwork at the edge of the elongated slot and, for example, with the aid of a nut or the like. to brace at the opposite end. As a result, the fastening bolt is already positively fixed in all directions and the like or corresponding forces without the additional use of support wedges or the like. record, tape. Installation is correspondingly simple.

Die Stabilität der Verbindung kann dadurch vergrößert sein, daß die Verbindungskupplung einen Kupplungsklotz mit dem Langschlitz aufweist, welcher über eine Verbindungslasche mit der Außenseite der einen Schaltafel verbunden ist und sich außerdem gegen die vorbeigeschalte Fortsetzung der Schalhaut der vorbeigeschalten Schaltafel abstützt. Dadurch können die von dem verspannten Bolzen übertragenen Kräfte besser aufgenommen werden, als wenn die Verbindungskupplung von zwei im wesentlichen unabhängigen parallelen Flacheisen gebildet ist.The stability of the connection can be increased in that the connection coupling has a coupling block with the elongated slot, which is connected via a connecting strap to the outside of the formwork panel and is also supported against the continuation of the formwork skin of the formwork panel that is switched over. As a result, the forces transmitted by the braced bolt can be absorbed better than if the connecting coupling is formed by two essentially independent parallel flat irons.

Die Enden des Langschlitzes können innerhalb der Abmessung des Kupplungsklotzes angeordnet sein, so daß eine gegenseitige Verformung der Langschlitzränder praktisch ausgeschlossen ist.The ends of the long slot can be arranged within the dimensions of the coupling block, so that mutual deformation of the long slot edges is practically impossible.

Besonders zweckmäßig ist es, wenn der vorbeigeschalte Bereich der Schaltafel in Reihe nebeneinanderliegende Haltelochungen für den Durchtritt des Befestigungsbolzens aufweist, die auf der Höhe des Langschlitzes der Verbindungskupplung angeordnet sind, und wenn der Langschlitz länger als der Abstand zwischen den nebeneinanderliegenden Haltelochungen ist. Dadurch wird eine spezielle, an der Stirnseite des vorbeigeschalten Bereiches angreifende Halterung für den Befestigungsbolzen vermieden. Darüber hinaus kann der Befestigungsbolzen im vorbeigeschalten Bereich jeweils möglichst nahe zu der auftreffenden Schaltafel angeordnet werden, um Hebelarme und Biegemomente möglichst klein zu halten.It is particularly useful if the switched-over area of the formwork panel has, in series, adjacent holding holes for the passage of the fastening bolt, which are arranged at the level of the elongated slot of the connecting coupling, and if the elongated slot is longer than the distance between the adjacent retaining holes. This avoids a special holder for the fastening bolt, which engages on the end face of the area switched past. In addition, the fastening bolt can be arranged as close as possible to the impacting panel in the shifted area in order to keep lever arms and bending moments as small as possible.

Eine besonders zweckmäßige Ausgestaltung der Erfindung, die eine nahezu stufenlose Verstellung des Säulenquerschnittes innerhalb der üblichen Bautoleranzen ermöglichen kann, kann darin bestehen, daß als Raststellen nebeneinanderliegende Zahnlücken einer Verzahnung am Rand des Langloches vorgesehen sind und der Befestigungsbolzen als Widerlager einen schneidenförmigen, über seinen Querschnitt ragenden Kopf hat, wobei die Schneide auf der Bolzenseite angeordnet ist und in Gebrauchsstellung in die Zahnlücken am Rand des Langloches paßt. Dabei können beide Längsränder des Langloches mit sich fortsetzenden Ausnehmungen, Zahnungen und Zahnlücken versehen sein und der schneidenförmige Kopf kann den Bolzen beidseitig überragen, damit ein symmetrischer Kraftangriff an den Rändern des Langloches und insbesondere auch eine Vergrößerung des Formschlusses erreicht wird. Denkbar wäre aber auch, daß die Verzahnung od.dgl. nur an einem Längsrand des Langloches mit einem entsprechenden schneidenförmigen Widerlager-Teil zusammenwirkt, während der andere Rand des Langloches glatt ist und das Widerlager sich dort dennoch zusätzlich abstützt.A particularly expedient embodiment of the invention, which can enable an almost infinitely variable adjustment of the column cross-section within the usual construction tolerances, can consist in that tooth gaps of toothing lying alongside one another are provided as rest points and the fastening bolt as an abutment has a cutting-shaped protrusion over its cross-section Has head, the cutting edge is arranged on the bolt side and in the position of use fits into the tooth gaps at the edge of the slot. Both longitudinal edges of the elongated hole can be provided with continuous recesses, serrations and tooth gaps and the cutting-shaped head can protrude from the bolt on both sides, so that a symmetrical force attack on the edges of the elongated hole and in particular also an increase in the form fit is achieved. But it would also be conceivable that the toothing or the like. only cooperates with a corresponding cutting-shaped abutment part on one longitudinal edge of the elongated hole, while the other edge of the elongated hole is smooth and the abutment is nevertheless additionally supported there.

Die Zahnlücken oder Rastausnehmungen können im Querschnitt etwa rechtwinklige Einschnitte sein, wobei die Winkelhalbierenden der rechten Winkel senkrecht zur verzahnten Oberfläche des Kupplungsklotzes verlaufen, und der Querschnitt der Schneide des Widerlagers des Verankerungsbolzens kann dem der Zahnlücken entsprechen. Dadurch ergibt sich beim Verspannen des Bolzens eine Selbstzentrierung und Ausrichtung, da die Schneide in jedem Fall in die entsprechend geformte Rastausnehmung hineingezogen wird. Darüber hinaus können Querkräfte auf den Bolzen nach beiden Seiten in gleicher Weise sicher übertragen bzw. aufgenommen werden.The tooth gaps or locking recesses can be approximately rectangular incisions in cross section, the bisector of the right angles being perpendicular to the toothed surface of the coupling block, and the cross section of the cutting edge of the abutment of the anchoring bolt can correspond to that of the tooth gaps. This results in self-centering and alignment when the bolt is clamped, since the cutting edge is always drawn into the correspondingly shaped locking recess. In addition, lateral forces on the bolt can be safely transmitted or absorbed on both sides in the same way.

Ausgestaltungen der Erfindung und insb esondere der Verbindungskupplung und ihres Verbindungsklotzes sind Gegenstand der Ansprüche 8 bis 12.Embodiments of the invention and in particular the connecting coupling and its connecting block are the subject of claims 8 to 12.

Vor allem bei Kombination der vorerwähnten und in den Ansprüchen enthaltenen Merkmale und Maßnahmen ergibt sich insgesamt eine Säulenschalung, bei welcher der Querschnitt der zu schalenden Säule praktisch beliebig innerhalb der Bautoleranzen gewählt werden kann, dennoch aber die Verbindung zwischen den jeweils über Eck benachbarten Schaltafeln einfach und schnell herstellbar ist, aber große Kräfte übertragen kann. Aufwendige zusätzliche Haltekeile und die Gefahr von zu großen Verformungen im Kupplungsbereich werden ebenso wie eine ständige feste Verbindung der Kupplung mit einer Schaltafel vermieden, so daß die Benutzung beliebiger Schaltafeln, wie sie auch für die Verschalung von Wänden benutzbar sind, möglich ist.Especially when combining the above-mentioned features and measures contained in the claims, there is overall a column formwork in which the cross-section of the column to be formed can be chosen practically as desired within the construction tolerances, but nevertheless the connection between the formwork panels neighboring each other is simple and can be produced quickly, but can transmit large forces. Elaborate additional holding wedges and the risk of excessive deformations in the coupling area are avoided, as is a permanent, permanent connection of the coupling to a formwork panel, so that the use of any formwork panels, such as can also be used for the formwork of walls, is possible.

Dies ermöglicht in bekannter Weise eine Veränderung des Querschnittes der zu erstellenden Säule dadurch, daß die Stirnseite 3 an unterschiedlichen Stellen der benachbarten Schaltafel auftreffen kann. Dadurch läßt sich nicht nur der Querschnitt quadratischer Säulen verändern, sondern es können auch rechteckige Säulen und diese wiederum mit praktisch beliebigen Querschnitt geschalt werden.A column formwork designated as a whole with 1 for columns to be concreted in cross-section in the exemplary embodiment has four formwork panels 2, each of which is connected past the end face 3 of a formwork panel adjacent to a corner. This enables the cross-section of the column to be created to be changed in a known manner in that the end face 3 can strike at different locations on the adjacent formwork panel. Not only can this change the cross-section of square columns, it can also be used to form rectangular columns, which in turn can be formed with practically any cross-section.

Zur Veränderung des Säulenquerschnittes ist jeweils eine im ganzen mit 4 bezeichnete Verbindungskupplung vorgesehen, die an der einen Schaltafel 2 im vorbeigeschalten Bereich 2a und an der anderen Schaltafel 2 auf deren Außenseite 2b angreift. Dabei greift diese Verbindungskupplung 4 einerseits an Aussteifungsstegen 5 der Außenseite 2b der Schaltafel 2 nahe ihrer Stirnseite 3 an, während sie andererseits mit Hilfe eines parallel zu dieser Schaltafel 2 verlaufenden, quer zu der vorbeigeschalten Schaltafel 2 orientierten, an der vorbeigeschalten Schaltafel 2 in dem vorbeigeschalten Bereich 2a verankerbaren Befestigungsbolzens 6 in der jeweiligen Position festlegbar ist.To change the column cross-section, a connection coupling, generally designated 4, is provided, which engages on one panel 2 in the area 2a switched past and on the other panel 2 on the outside 2b thereof. This connection coupling 4 engages on the one hand on stiffening webs 5 on the outside 2b of the formwork panel 2 near its end face 3, while on the other hand it shifts past the formwork panel 2 in the past with the help of a formwork 2 parallel to this formwork panel 2 and oriented transversely to the formwork panel 2 Area 2a of anchored fastening bolt 6 can be fixed in the respective position.

Vor allem in den Figuren 2 und 4 erkennt man dabei, daß der Befestigungsbolzen 6 einen Langschlitz 7 an der Verbindungskupplung 4 quer zur Orientierung dieses Langschlitzes 7 durchsetzt und auf der der vorbeigeschalten Schaltafel abliegenden Seite mit Hilfe eines Widerlagers 8 übergreift (vgl. auch Fig. 1 und 5), welches durch eine Verankerung des Befestigungsbolzen 6 im Ausführungsbeispiel mittels einer Mutter 9 gegen die Verbindungskupplung 4 zur Anlage bringbar und verspannbar ist. Durch diese Verbindung ist die Stirnseite der stumpf auftreffenden Schaltafel fest gegen die vorbeigeschalte Schaltafel anziehbar.Especially in Figures 2 and 4, it can be seen that the fastening bolt 6 passes through an elongated slot 7 on the connecting coupling 4 transversely to the orientation of this elongated slot 7 and overlaps on the side remote from the switching panel with the aid of an abutment 8 (cf. also FIG. 1 and 5), which can be brought into contact and braced against the connection coupling 4 by anchoring the fastening bolt 6 in the exemplary embodiment by means of a nut 9. Through this connection, the face of the butt-hitting formwork panel can be tightened firmly against the formwork panel that has passed.

Um eine formschlüssige Verbindung herzustellen und zu verhindern, daß der Betonierdruck oder sonstige Kräfte die stumpf auftreffende Schaltafel 2 gegenüber der vorbeigeschalten Schaltafel in irgend einer Weise verschieben können, ist der von dem Widerlager 8 des Befestigungsbolzens 6 beaufschlagte Rand 10 des Langschlitzes 7 mit in seiner Orientierungsrichtung nebeneinanderliegenden Raststellen oder -vertiefungen 11 versehen, in welche das Widerlager 8 formschlüssig teilweise eingreifen kann. Dadurch kann die Verbindungskupplung 4 über den Befestigungsbolzen 6 in Orientierungsrichtung der vorbeigeschalten Schaltafel auftretende Kräfte formschlüssig und damit mit großer Sicherheit übertragen, ohne daß es für diese formschlüssige Verbindung zusätzlicher Verankerungsteile an dem Befestigungsbolzen 6 bedarf.In order to establish a positive connection and to prevent the concreting pressure or other forces from shifting the butt-impacting panel 2 in any way relative to the panel that is switched past, the edge 10 of the elongated slot 7 which is acted upon by the abutment 8 of the fastening bolt 6 is in its orientation direction adjacent resting points or depressions 11 are provided, in which the abutment 8 can interlock partially. As a result, the connection coupling 4 can be oriented via the fastening bolt 6 The direction of the switched-over formwork panel forces are transmitted positively and thus with great certainty without the need for additional anchoring parts on the fastening bolt 6 for this positive connection.

Im Ausführungsbeispiel weist die Verbindungskupplung 4 einen Kupplungsklotz 11 a mit dem Langschlitz 7 auf, welcher über eine Verbindungslasche 12 mit der Außenseite 2b der einen Schaltafel 2 lösbar verbindbar ist, so daß diese Schaltafel 2 auch für andere Schalungszwecke zur Verfügung steht. Außerdem stützt sich der Kupplungsklotz 11 gemäßIn the exemplary embodiment, the connecting coupling 4 has a coupling block 11 a with the elongated slot 7, which can be releasably connected to the outside 2 b of the one formwork panel 2 via a connecting strap 12, so that this formwork panel 2 is also available for other formwork purposes. In addition, the clutch block 11 is supported according to

Fig. 1 und 2 gegen die vorbeigeschalte Fortsetzung 2a der Schalhaut 13 der vorbeigeschalten Schaltafel 2 ab. Diese Abstützung wird durch die am Befestigungsbolzen 6 mit Hilfe der Mutter 9 aufgebrachte Zugkraft verstärkt und gesichert. Dabei sind die Enden des Langschlitzes 7 innerhalb der Abmessung des Kupplungsklotzes 11a angeordnet, so daß auch die Form des Langschlitzes 7 stabil ist gegenüber einem Langschlitz, der zwischen zwei separaten Flacheisen oder Profilen verlaufen würde.1 and 2 against the pasted continuation 2a of the formwork skin 13 of the pasted formwork panel 2. This support is reinforced and secured by the tensile force applied to the fastening bolt 6 with the aid of the nut 9. The ends of the elongated slot 7 are arranged within the dimension of the coupling block 11a, so that the shape of the elongated slot 7 is also stable with respect to an elongated slot which would run between two separate flat bars or profiles.

Gemäß Fig. 1 hat der vorbeigeschalte Bereich 2a der Schaltafel 2 in Reihe nebeneinanderliegende Haltelochungen 14 für den Durchtritt des Befestigungsbolzens 6 und auch dessen Verankerung mit Hilfe der Mutter 9, die auf der Höhe des Langschlitzes 7 der Verbindungskupplung 4 angeordnet sind. Der Langschlitz 7 ist dabei vorzugsweise etwas länger als der Abstand zwischen den nebeneinanderliegenden Haltelochungen 14 oder könnte auch in seiner Länge gerade genau diesem Abstand entsprechen. Somit können die Abmessungen der zu schalenden Säule stufenförmig dadurch verändert werden, daß der Befestigungsbolzen 6 jeweils an einer anderen Haltelochung 14 der erwähnten Reihe von solchen Haltelochungen 14 angesetzt werden kann. Der Zwischenabstand zwischen jeweils benachbarten Haltelochungen 14 kann dann mit Hilfe des Langschlitzes 7 praktisch stufenlos überbrückt und gewählt werden, so daß eine praktisch stufenlose Querschnittsänderung einer zu schalenden Säule möglich ist. Es verbleiben lediglich geringfügige Sprünge von einer Rastvertiefung 11 zur benachbarten. Dabei können als Rastvertiefungen 11 nebeneinanderliegende Zahnlücken einer Verzahnung am Rand 10 des Langloches 7 vorgesehen sein, wie man es in Fig. 3 gut erkennt. Der Befestigungsbolzen 6 hat als dazu passendes Widerlager 8 einen schneidenförmigen, über seinen Querschnitt ragenden Kopf, wobei die Schneide 15 gemäß Fig. 5 auf der Bolzenseite dieses Widerlagers 8 angeordnet ist und in Gebrauchsstellung in die Zahnlücken am Rand 10 des Langloches 7 paßt, wie es vor allem in Fig. 1 angedeutet ist. Dabei sind gemäß Fig. 2 und 4 beide Längsränder 10 des Langschlitzes 7 mit sich fortsetzenden Zahnungen und Zahnlücken als Rastvertiefungen 11 versehen und der schneidenförmige Kopf des Bolzens überragt diesen beidseitig.1, the switched-over region 2a of the formwork panel 2 has holding holes 14 lying next to one another in series for the passage of the fastening bolt 6 and also for anchoring it with the aid of the nut 9, which are arranged at the height of the elongated slot 7 of the connecting coupling 4. The elongated slot 7 is preferably somewhat longer than the distance between the holding holes 14 lying next to one another or could also correspond exactly to this distance in terms of its length. Thus, the dimensions of the column to be shuttered can be changed stepwise in that the fastening bolt 6 can each be attached to a different holding hole 14 of the aforementioned series of such holding holes 14. The intermediate distance between adjacent holding holes 14 can then be bridged and selected practically infinitely with the aid of the elongated slot 7, so that a practically infinitely variable change in cross-section of a column to be formed is possible. There are only slight jumps from a locking recess 11 to the neighboring one. In this case, adjacent tooth gaps of a toothing at the edge 10 of the elongated hole 7 can be provided as locking recesses 11, as can be seen well in FIG. 3. The fastening bolt 6 has as a matching abutment 8 a cutting-shaped head that projects beyond its cross section, the cutting edge 15 according to FIG. 5 being arranged on the bolt side of this abutment 8 and in the use position in the tooth gaps at the edge 10 of the elongated hole 7, as it fits is particularly indicated in Fig. 1. 2 and 4, both longitudinal edges 10 of the elongated slot 7 are provided with continuous serrations and tooth gaps as locking recesses 11 and the blade-shaped head of the bolt projects beyond it on both sides.

Im Ausführungsbeispiel sind die Zahnlücken oder Rastausnehmungen 11 gemäß Fig. 3 im Querschnitt etwa rechtwinklige Einschnitte, wobei die Winkelhalbierenden der rechten Winkel senkrecht zur verzahnten Oberfläche des Kupplungsklotzes 11a verlaufen. Der Querschnitt der Schneide 15 des Widerlagers 8 des Verankerungsbolzens 6 entspricht dabei dem der Zahnlücken 11. Somit können viele derartige Rastausnehmungen 11 einander unmittelbar benachbart angeordnet werden, so daß sehr geringe Abstände von Ausnehmung 11 zu Ausnehmung 11 entstehen, die noch innerhalb der auf dem Bau üblichen Toleranzen liegen können, so daß unterschiedliche Abmessungen einer zu schalenden Säule praktisch stufenlos vergrößert oder verkleinert gewählt werden können. Dabei kann die Tiefe der Rastausnehmung 11 etwa 1 bis 3 mm, vorzugsweise etwa 2 mm betragen. Entsprechen nah können diese Ausnehmungen 11 zueinander angeordnet sein.In the exemplary embodiment, the tooth gaps or locking recesses 11 according to FIG. 3 are approximately rectangular incisions in cross section, the bisectors of the right angles being perpendicular to the toothed surface of the coupling block 11a. The cross section of the cutting edge 15 of the abutment 8 of the anchoring bolt 6 corresponds to that of the tooth spaces 11. Thus, many such recesses 11 can be arranged directly adjacent to one another, so that very small distances from recess 11 to recess 11 arise, which are still within the construction usual tolerances can be, so that different dimensions of a column to be shuttered can be selected practically continuously enlarged or reduced. The depth of the recess 11 can be about 1 to 3 mm, preferably about 2 mm. Correspondingly, these recesses 11 can be arranged in relation to one another.

Gemäß Fig. 3 ist die der Verzahnung gegenüberliegende Oberfläche des Kupplungsklotzes 11 a als glatte Anschlagfläche zum Anlegen an die Schalhaut 13 des vorbeigeschalten Bereiches 2a der Schaltafel 2 ausgebildet. Dabei ist im Ausführungsbeispiel der Kupplungsklotz 11 a auf einer ihn in seiner quer zu Erstreckung des Langloches 7 verlaufenden Breite übertreffenden Anlageplatte 16 befestigt, insbesondere aufgeschweißt. Dadurch können die durch das Verspannen des Bolzens 6 erzeugten Anlagekräfte des Kupplungsklotzes 11a besser auf die empfindliche Schalhaut 13 verteilt werden.According to FIG. 3, the surface of the coupling block 11a opposite the toothing is designed as a smooth abutment surface for contacting the formwork skin 13 of the area 2a of the formwork panel 2 switched past. In the exemplary embodiment, the coupling block 11a is fastened, in particular welded, to an abutment plate 16 which exceeds its width, which extends transversely to the elongated hole 7. As a result, the contact forces of the coupling block 11a generated by the bracing of the bolt 6 can be better distributed to the sensitive formwork skin 13.

Um einen sicheren Angriff an der stumpf auftreffenden Schaltafel innerhalb von Randstegen zu erlauben, ist es vorteilhaft, wenn die in Richtung des Befestigungsbolzens 6 verlaufende Dicke des Kupplungsklotzes 11a zwischen Anlagefläche und Verzahnung wenigstens etwa einem Fünftel oder Viertel bis einem Drittel der Länge des Bolzens 6 entspricht. Darüber hinaus wird so der den Langschlitz 7 enthaltende Kupplungsklotz 11a entsprechend stabil, so daß ungewünschte Verformungen des Langschlitzes 7 praktisch ausgeschlossen sind.In order to allow a secure attack on the formwork plate which bluntly meets within edge webs, it is advantageous if the thickness of the coupling block 11a in the direction of the fastening bolt 6 between the contact surface and the toothing corresponds to at least about a fifth or a quarter to a third of the length of the bolt 6 . In addition, the coupling block 11a containing the elongated slot 7 becomes correspondingly stable, so that undesired deformations of the elongated slot 7 are practically excluded.

Es sei noch erwähnt, daß die Verbindungslasche 12 zum Verbinden mit der stumpf auf die vorbeigeschalte Schaltafel 2 stoßenden Schaltafel 2 an einer quer zur Erstreckung des Langschlitzes 7 angeordneten Schmalseite des Kupplungsklotzes 11a befestigt, im Ausführungsbeispiel angeschweißt ist und mit ihrem Querschnitt gegenüber dieser Seite vorsteht, mit ihrer Längserstreckung aber den verzahnten Bereich des Kupplungsklotzes 11 a überragt und vorzugsweise mehrere Kupplungsstellen, insbesondere Lochungen 17 zum Verbinden mit entsprechenden Lochungen 18 an einem Aussteifungssteg 5 der Schaltafel 2 hat. Man erkennt diese zu der Verbindungskupplung 4 gehörende Verbindungslasche 12 gut in Fig. 1 und 2 und erkennt dort auch, daß sie zwei schlüssellochartige Lochungen 18 eines Aussteifungssteges 5 übergreifen kann, so daß eine entsprechend stabile und auch schwenkfeste Verbindung möglich ist.It should also be mentioned that the connecting tab 12 for connecting to the formwork panel 2 butting past the formwork panel 2 is fastened to a narrow side of the coupling block 11a arranged transversely to the extension of the elongated slot 7, is welded in the exemplary embodiment and projects with its cross section opposite this side, with its longitudinal extent, however, projects beyond the toothed area of the coupling block 11 a and preferably has a plurality of coupling points, in particular perforations 17 for connecting to corresponding perforations 18 on a stiffening web 5 of the formwork panel 2. You can see this belonging to the connecting coupling 4 connecting tab 12 well in Fig. 1 and 2 and there you can also see that it can overlap two keyhole-like holes 18 of a stiffening web 5, so that a correspondingly stable and swivel-resistant connection is possible.
