Abstract

PCT No. PCT/DE88/00440 Sec. 371 Date Jan. 29, 1990 Sec. 102(e) Date Jan. 29, 1990 PCT Filed Jul. 16, 1988 PCT Pub. No. WO89/01083 PCT Pub. Date Feb. 9, 1989.A form for the pouring of concrete has first and second panels which are disposed edge-to-edge. Each of the panels has a flange projecting from the major surface of the respective panel and the flanges have confronting first surfaces which are perpendicular to the major surfaces of the panels and are designed to abut one another. The flanges have second surfaces which face away from the first surfaces and the second surfaces are inclined to the major surfaces of the panels so that the flanges narrow in a direction away from the panels. A clamping element designed to embrace the flanges is pivotally mounted on the first panel and is movable between a released position and a clamping position in which it embraces the flanges. The second panel carries an abutment and the clamping element has a free end which is located between the abutment and the flange of the second panel in the clamping position. A wedge-like slide is mounted on the free end of the clamping element for movement between a retracted position and an extended position. The arrangement is such that, when the clamping element is in its clamping position and the slide is moved to its extended position, the slide pushes against the abutment thereby causing the clamping element to urge the flanges into engagement with one another.

Description

Die Erfindung betrifft eine Verbindungsvorrichtung mit einem Klemmbügel für Schaltafeln, die an ihren Rändern rechtwinklig zur Schalhaut abstehende Randstege aufweisen, welche in Gebrauchsstellung von dem Klemmbügel umgriffen sind, wobei der Klemmbügel um eine Achse parallel zu einem der Randstege in eine Löseposition und in eine Gebrauchsstellung schwenkbar ist und in Gebrauchsstellung mit einem der Schwenklagerung abgewandten freiem Bügelarm an einem parallel zu dem zweiten Randsteg verlaufenden Stab od.dgl. befestigbar und derart spannbar ist, daß die beiden aneinanderliegenden Randstege zusammengedrückt, sind und wobei die Achse und der Stab jeweils mit einer der zu verbindenden Schaltafeln fest verbunden und parallel zur Längsrichtung der zu verbindenden Randstege angeordnet sind.The invention relates to a connecting device with a clamping bracket for formwork panels which have edge webs projecting at their edges at right angles to the formlining, which are encompassed by the clamping bracket in the use position, the clamping bracket being pivotable about an axis parallel to one of the edge webs into a release position and into a use position is and in the use position with a free bracket arm facing away from the pivot bearing on a parallel to the second edge web rod or the like. can be fastened and tensioned in such a way that the two adjoining edge webs are pressed together, and the axis and the rod are each firmly connected to one of the formwork panels to be connected and are arranged parallel to the longitudinal direction of the edge webs to be connected.

Eine vergleichbare Verbindungsvorrichtung ist aus der US-PS 3 550 898 bekannt. Der schwenkbare Klemmbügel ist dabei zweiteilig ausgebildet., wobei der freie Bügelarm relativ zu dem. schwenkbar gelagerten Bügelarm verschiebbar geführt sein muß und in eine Spannstellung zurückgezogen wird. Die Zurückziehung erfolgt dabei mittels eines Keiles, der Langschlitze an den beiden zusammengehörenden Bügelteilen durchsetzt. Der freie Bügelarm. ist dabei hakenartig ausgebildet und übergreift einen Stab oder Bolzen in Gebrauchsstellung. Dadurch können zwar die Randstege zweier Schaltafeln zusammengezogen werden, jedoch besteht aufgrund des nicht zu vermeidenden Spieles innerhalb der einzelnen zu dieser Verbindungsvorrichtung gehörenden Teile die Gefahr, daß sie gegeneinander versetzt zusammengespannt werden und später im Beton Abstufungen entstehen.A comparable connecting device is known from US Pat. No. 3,550,898. The pivotable clamp bracket is formed in two parts, the free bracket arm relative to the. pivoting bracket arm must be slidably guided and withdrawn into a clamping position. The retraction takes place by means of a wedge, which passes through elongated slots on the two bracket parts belonging together. The free arm. is designed like a hook and overlaps a rod or bolt in Position of use. As a result, the edge webs of two formwork panels can be pulled together, but due to the unavoidable play within the individual parts belonging to this connecting device, there is a risk that they will be clamped together offset and later gradations will occur in the concrete.

Es besteht deshalb die Aufgabe, eine Verbindungsvorrichtung der eingangs erwähnten Art zu schaffen, mit welcher gleichzeitig ein Ausrichten der zu verbindenden Schaltafeln ermöglicht wird. Ein separater, eventuell verlorengehender Keil soll vermieden werden.The object is therefore to create a connecting device of the type mentioned at the outset, with which an alignment of the formwork panels to be connected is made possible at the same time. A separate, possibly lost wedge should be avoided.

Zur Lösung dieser Aufgabe ist die Verbindungsvorrichtung der eingangs erwähnten Art dadurch gekennzeichnet, daß der Klemmbügel in Gebrauchsstellung die voneinander abgewandten Flächen der Randstege zumindest bereichsweise formschlüssig umgreift und daß zum Verspannen des freien Bügelarmes an dem Stab ein etwa in Richtung des Bügelendes verschiebbares Verlängerungsstück vorgesehen ist, welches nach dem Verschieben den Stab klemmend untergreift. Durch den Formschluß wird beim Verspannen auch ein Ausrichten der Schalung ermöglicht bzw. eine ausgerichtete Schaltafel in dieser Position festgelegt. Das verschiebbare Verlängerungsstück macht einen separaten Spannkeil überflüssig.To solve this problem, the connecting device of the type mentioned is characterized in that the clamping bracket in the position of use at least partially positively engages around the surfaces of the edge webs facing away from one another and that an extension piece which can be displaced approximately in the direction of the bracket end is provided for bracing the free bracket arm, which clamps under the rod after moving. Alignment of the formwork is also made possible by the positive connection when bracing or an aligned formwork panel is fixed in this position. The sliding extension piece makes a separate wedge unnecessary.

Besonders gut und sicher kann eine Ausrichtung der zu verbindenden Schaltafeln in Flucht miteinander erzielt werden, wenn die freien Ränder der Randstege in Gebrauchsstellung an der Bügelinnenseite anliegen. Durch das Verspannen und Festlegen des Klemmbügels können dadurch eventuell geringfügige Versetzungen der Randstege noch beseitigt werden.Alignment of the formwork panels to be connected in alignment with one another can be achieved particularly well and safely if the free edges of the edge webs bear against the inside of the bracket in the use position. By tightening and fixing the clamp, any slight dislocations of the edge webs can still be eliminated.

Das Verlängerungsstück kann bevorzugt an einem Vorsprung des freien Bügelarmes angeordnet sein, welcher an dem Stab vorbeischwenkbar ist und in Gebrauchsstellung einen Abstand zu dem Stab hat. Somit kann der Bügelarm bei zurückgezogenem Verlängerungsstück bequem an dem Stab vorbei in seine Gebrauchslage verschwenkt oder nach dem Zurückziehen des Verlängerungsstückes wieder in Lösestellung gebracht werden und in Gebrauchsstellung kann dann die Festlegung und Verspannung durch das Ausschieben des Verlängerungsstückes auf einfache Weise erfolgen. Dabei ist es besonders zweckmäßig, wenn das verschiebbare Verlängerungsstück mit seiner dem Stab zugewandten Oberseite schräg zu seiner Verschieberichtung und der untergriffenen Stabseite verläuft, wobei die Schrägung entgegen der Schieberichtung ansteigt. Dadurch kann beim Festlegen des Klemmbügels in seiner Gebrauchsstellung mit Hilfe des verschiebbaren Verlängerungsstückes von diesem gleichzeitig eine Spannwirkung aufgrund der erwähnten Schrägung erzielt werden. Ebenso kann dadurch später das Lösen begünstigt werden.The extension piece can preferably be arranged on a projection of the free bracket arm, which can be swiveled past the rod and is at a distance from the rod in the use position. Thus, when the extension piece is withdrawn, the bow arm can be pivoted conveniently past the rod into its position of use or, after the extension piece has been pulled back, can be brought back into the release position and in the use position, the fixing and tensioning can then be carried out in a simple manner by pushing out the extension piece. It is particularly expedient if the displaceable extension piece, with its upper side facing the rod, runs obliquely to its direction of displacement and the underneath rod side, the inclination increasing counter to the direction of displacement. As a result, when the clamp is set in its position of use with the aid of the displaceable extension piece, a tensioning effect can be achieved on the basis of the aforementioned inclination. Likewise, the release can be promoted later.

Eine einfache Konstruktion ergibt sich, wenn das Verlängerungsstück auf einer etwa parallel zur Stabunterseite verlaufenden Abstützung verschiebbar ist und als Keil ausgebildet ist. Dadurch ergibt sich bei der erwähnten gleichbleibenden Verschiebung des Verlängerungsstückes in seine Spannstellung die erwünschte Verkeilung und Verspannung, die auch als Festlegung ausreicht und die erwünschten Klemmkräfte schnell und einfach erzeugen kann. Dabei kann der Befestigungs- und Spannkeil - zusätzlich zu der Führung an seiner dem Stab abgewandten Unterseite - mittels eines Querstiftes od.dgl. unverlierbar in einem Langschlitz geführt sein. Ferner kann der Klemmbügel auf der insbesondere fest installierten Schwenkachse unverlierbar gelagert sein, so daß die gesamte Befestigungsvorrichtung in vorteilhafter Weise mit der jeweiligen Schaltafel verbunden ist und bleibt und gewissermaßen der Schalung integriert ist.A simple construction results if the extension piece is displaceable on a support running approximately parallel to the underside of the rod and is designed as a wedge. This results in the aforementioned constant displacement of the extension piece into its clamping position, the desired wedging and bracing, which is also sufficient as a fixation and can generate the desired clamping forces quickly and easily. The fastening and clamping wedge - in addition to the guide on its underside facing away from the rod - or the like by means of a cross pin. be captively guided in a long slot. Furthermore, the clamping bracket can be mounted so that it cannot be lost on the, in particular, permanently installed pivot axis, so that the entire fastening device is and remains connected to the respective formwork panel in an advantageous manner and to a certain extent the formwork is integrated.

Eine besonders günstige Kraftübertragung ergibt sich, wenn der freie Bügelarm mit dem Verlängerungsstück zwischen dem Randsteg und dem Verankerungsstab in seine Gebrauchsstellung einschwenkbar ist. Wird dann zwischen dem freien Bügelarm und dem Stab das Verlängerungsstück eingeschoben und verkeilt, ergibt sich die gewünschte Andrückung an den zu haltenden Randsteg.A particularly favorable power transmission results if the free bracket arm with the extension piece between the edge web and the anchoring rod can be pivoted into its position of use. If the extension piece is then inserted and wedged between the free bracket arm and the rod, the desired pressure results on the edge web to be held.

Für eine einfache und dennoch wirkungsvolle Verschiebung des Verlängerungsstückes kann dieses an seinem dem Befestigungsende abgewandten Ende einen gegenüber der Führung und dem Bügelarm vorstehenden Vorsprung für den Angriff eines Werkzeuges, insbesondere eines Hammers aufweisen. Dies begünstigt nicht nur das Einschlagen des Verlängerungsstückes in seine Gebrauchsstellung sondern auch das Lösen, wobei dann gegen die Unterseite dieses Vorsprunges geschlagen oder daran gezogen werden kann.For a simple yet effective displacement of the extension piece, the extension piece can have at its end facing away from the fastening end a protrusion protruding from the guide and the bracket arm for the attack of a tool, in particular a hammer. This not only favors the turning of the extension piece into its position of use but also the loosening, which can then be struck or pulled against the underside of this projection.

Die Innenkontur des Klemmbügels kann der Außenkontur der beiden aneinanderliegenden Randstege weitgehend entsprechen, wobei der freie Bügelarm zweckmäßigerweise einen in das Bügelinnere gerichteten Vorsprung als Anschlag gegen den stabseitigen Randsteg hat. Somit liegt an diesem stabseitigen Randsteg der Bügelarm nicht unbedingt über seine gesamte Länge an, so daß gewisse Maßunterschiede, Toleranzen und Spannwege ausgeglichen und das Ende des Bügelarmes mit Sicherheit in Anschlag mit dem entsprechenden Randsteg gebracht werden kann, da der erwähnte Vorsprung zweckmäßigerweise am Ende des Bügelarmes vorgesehen ist. Um durch das Verschwenken des Klemmbügels in seine Gebrauchsstellung schon eine gewisse Bewegung der beiden Randstege aufeinanderzu zu bewirken, können die beiden Randstege an ihren ihren Berührflächen abgewandten Oberseiten von der Schalhaut zu ihren freien Rändern im Querschnitt schräg verlaufen und zusammen etwa ein Trapez bilden und die Bügelöffnung kann dementsprechend im wesentlichen trapezförmig sein.The inner contour of the clamping bracket can largely correspond to the outer contour of the two adjoining edge webs, the free bracket arm expediently having a projection directed into the interior of the bracket as a stop against the rod-side edge web. Thus, on this rod-side edge web, the bow arm does not necessarily lie over its entire length, so that certain dimensional differences, tolerances and clamping paths can be compensated for and the end of the bow arm can be brought into contact with the corresponding edge web with certainty, since the aforementioned projection is expediently at the end of the Arm is provided. In order to bring about a certain movement of the two edge webs towards one another by pivoting the clamping bracket into its position of use, the two edge webs on their upper surfaces facing away from their contact surfaces can run obliquely in cross-section from the formlining to their free edges and together form approximately a trapezoid and the bracket opening can accordingly be substantially trapezoidal.

Um eine wirkungsvolle Anlage des Klemmbügels auch an dem lagerseitigen Randsteg der .mit dem Bügel versehenen Schaltafel zu erreichen, kann das Lagerauge des Schwenklagers des Klemmbügels als Exzenter ausgebildet sein und in Offenstellung einen etwa dem Doppelten der Exzentrizität entsprechenden lichten Abstand von dem ihm benachbarten Randsteg haben und in Schließstellung mit der Bügelinnenseite an den Randsteg angedrückt sein. Dadurch wird dann die von dem Bügel auf den Randsteg der anderen Schaltafel zu übertragende Kraft nicht ausschließlich über das Lager, sondern auch in erwünschter Weise über den lagerseitigen Randsteg übertragen.In order to achieve an effective contact of the clamping bracket also on the bearing-side edge web of the formwork panel provided with the bracket, the bearing eye of the pivot bearing of the clamping bracket can be designed as an eccentric and, in the open position, have a clear distance approximately twice the eccentricity from the adjacent edge web and be pressed against the edge web with the inside of the bow in the closed position. As a result, the force to be transmitted from the bracket to the edge web of the other formwork panel is then transmitted not only via the bearing but also in a desired manner via the edge web on the bearing side.

Der Stab zur Verankerung des Klemmbügels in seiner Gebrauchsstellung kann eine im Querschnitt ebene Unterseite für die Anlage der Verlängerung haben, vorzugsweise als Vierkantrohr od.dgl. ausgebildet sein, wobei der Querschnitt seiner Unterseite etwa parallel zur Schieberichtung des Verlängerungsstückes orientiert sein kann. Dabei kann die Schieberichtung des Verlängerungsstückes unter einem weniger spitzen Winkel zu einer Senkrechten zur Schalhaut stehen als der freie Bügelarm und seine an dem Randsteg anlegbare Innenseite. Somit kann durch das Ausschieben des Verlängerungsstückes nicht nur eine Klemmwirkung, sondern gleichzeitig ein gewisser Formschluß in Gebrauchsstellung erzielt werden, weil dann das Verlängerungsstück den Stab so untergreift, daß ein Aufschwenken nicht mehr möglich ist. Es wird also gleichzeitig eine Verriegelung erzielt und das Verlängerungsstück wirktnicht nur als Spannelement sondern auch als Sperriegel.The rod for anchoring the clamping bracket in its position of use can have an underside which is flat in cross section for the attachment of the extension, preferably as a square tube or the like. be formed, the cross section of its underside can be oriented approximately parallel to the sliding direction of the extension piece. The sliding direction of the extension piece can be at a less acute angle to a perpendicular to the formlining than the free bracket arm and its inside that can be placed on the edge web. Thus, by pushing out the extension piece, not only a clamping effect, but at the same time a certain form fit can be achieved in the position of use, because then the extension piece engages under the rod in such a way that pivoting open is no longer possible. A lock is thus achieved at the same time and the extension piece acts not only as a tensioning element but also as a locking bolt.

Es sei noch erwähnt, daß die Schwenkachse für den Bügel und vorzugsweise der Befestigungsstab zwischen rechtwinklig zu den verbindenden Randstegen angeordneten Stegen der Schaltafel verlaufen und/oder an diesen Stegen verankert sein können, so daß es spezieller Gehäuse oder Lagerungen nicht bedarf, sondern Aussteifungsstege der Schaltafeln zur Verankerung der gesamten Befestigungsvorrichtung ausgenutzt werden können. Weitere Ausgestaltungen der erfindungsgemäßen Vorrichtung und dabei Möglichkeiten, den Klemmbügel unverlierbar zu gestalten, ihn aber evtl. trotzdem leicht demontieren und umsetzen zu können sowie Ausgestaltungen, die eine symmetrische und somit beliebige Anordnung ergeben, sind Gegenstand der Ansprüche 15 bis 22. Vor allem die Kombination einer spiegelsymmetrischen Anordnung und Ausgestaltung der Schwenkachsen und Stäbe mit der Möglichkeit, den Klemmbügel aufgrund einer verschließbaren Unterbrechung seiner Durchtrittsöffnung für die Schwenkachse trotz seiner Unverlierbarkeit auch demontieren zu können, erlaubt es, eine in einem Anwendungsfall die Schwenkachse bildenden Stab im anderen Fall als Befestigungsstab für das verschiebbare Verlängerungsstück zu verwenden und den Klemmbügel an dem vorher zur Verankerung des Verlängerungsstückes dienenden Stab schwenkbar zu befestigen. Somit können Klemmbügel und Schaltafeln in nahezu beliebiger Form kombiniert werden und es muß beim Verbinden der Schaltafeln nicht streng darauf geachtet werden, daß jeweils an dem Verbindungsbereich auf der einen Seite eine Schwenkachse und auf der anderen Seite ein Befestigungsstab zu liegen kommen.It should also be mentioned that the pivot axis for the bracket and preferably the fastening rod run between webs of the formwork panel arranged at right angles to the connecting edge webs and / or anchored to these webs can be, so that there is no need for special housings or bearings, but stiffening webs of the formwork panels can be used to anchor the entire fastening device. Further refinements of the device according to the invention and possibilities to make the clamping bracket captive, but possibly still easy to disassemble and implement, as well as refinements which result in a symmetrical and thus any arrangement, are the subject of claims 15 to 22. Above all, the combination A mirror-symmetrical arrangement and design of the swivel axes and rods with the possibility of also being able to dismantle the clamping bracket due to a lockable interruption of its passage opening for the swivel axis, despite its captivity, allows a rod that forms the swivel axis in one application case as a fastening rod for the other to use slidable extension piece and to pivotally attach the clamp to the rod previously used to anchor the extension piece. Thus, clamps and formwork panels can be combined in almost any shape and it is not necessary to pay strict attention when connecting the formwork panels that a swivel axis and a fastening rod come to rest on the connection area on the one side.

Die Anordnung solcher Schwenkachsen bzw. Stäbe auch entlang den kürzeren Schmalseiten und Rändern der Schaltafeln erlaubt außerdem eine beliebige Anordnung dieser Schaltafeln auch in um 90° gedrehter Posititon und dies in Kombination mit nicht in dieser gedrehten Position angeordneten Schaltafeln. Beispielsweise lassen sich dadurch Schalungswände, die von mit den längeren Rändern vertikal angeordneten Schaltafeln gebildet sind, aufstocken, weil nun um 90° gedrehte Schaltafeln auf die oberen Ränder solcher Schaltafeln aufgesetzt und mit dem Klemmbügel fixiert werden können.The arrangement of such swivel axes or rods also along the shorter narrow sides and edges of the formwork panels also allows any arrangement of these formwork panels in a position rotated by 90 ° and this in combination with formwork panels not arranged in this rotated position. For example, this enables formwork walls, which are formed by formwork panels arranged vertically with the longer edges, because formwork panels rotated by 90 ° can now be placed on the upper edges of such formwork panels and fixed with the clamping bracket.

Nachstehend ist die Erfindung mit ihren ihr als wesentlich zugehörenden Einzelheiten in mehreren Ausführungsbeispielen anhand der Zeichnung noch näher beschrieben.The invention is described in more detail in several exemplary embodiments with the aid of the drawing, with the details that belong to it.

Eine im ganzen mit 1 bezeichnete Verbindungsvorrichtung für Schaltafeln 2, die an ihren Rändern rechtwinklig zur Schalhaut 3 abstehende Randstege 4 aufweisen, umfaßt vor allem einen Klemmbügel 5, der in der mit durchgezogenen Strichen dargestellten Gebrauchsstellung die beiden Randstege 4 von in Flucht miteinander zu verbindenden Schaltafeln 2 umgreift.A generally designated 1 connecting device for formwork panels 2, which have edge webs 4 projecting at their edges at right angles to the formlining 3, comprises in particular a clamping bracket 5 which, in the position of use shown with solid lines, the two edge webs 4 of formwork panels to be connected in alignment 2 embraces.

Der Klemmbügel 5 ist dabei um eine Achse 6 parallel zu dem ihm benachbarten Randsteg 4 in eine mit strichpunktierten Linien dargestellte Löseposition und aus dieser Löseposition umgekehrt in die Gebrauchsstellung schwenkbar.The clamping bracket 5 can be pivoted about an axis 6 parallel to the edge web 4 adjacent to it into a release position shown in dash-dotted lines and vice versa into the use position.

In der Gebrauchsstellung ist der Klemmbügel 5 mit seinem der Schwenklagerung und der Schwenkachse 6 abgewandten freien Bügelarm 7 an einem parallel zu dem zweiten Randsteg verlaufenden Stab 8 in noch zu beschreibender Weise befestigbar und derart spannbar, daß die beiden aneinanderliegenden Randstege 4 in der dargestellten Weise zusammengedrückt werden.In the position of use, the clamping bracket 5 with its free bracket arm 7 facing away from the pivot bearing and the pivot axis 6 can be fastened to a rod 8 running parallel to the second edge web in a manner to be described and can be tensioned such that the two adjoining edge webs 4 are compressed in the manner shown will.

Um die beiden Schaltafeln 2 in einer fluchtenden Position zusammenzuhalten und gegebenenfalls beim Verspannen noch etwas auszurichten, umgreift der Klemmbügel 5 in Gebrauchsstellung die voneinander abgewandten Oberflächen 9 der Randstege 4 zumindest bereichsweise formschlüssig. Ferner liegen in dieser Gebrauchsstellung für eine gute Ausrichtung die freien Ränder 4a der Randstege 4 an der entsprechenden Bügelinnenseite an. Zum Verspannen des freien Bügelarmes 7 an dem Stab 8 ist ein etwa in Richtung des freien Bügelendes verschiebbares Verlängerungsstück 10 vorgesehen, welches nach dem Verschieben den Stab 8 - wie in der Zeichnung dargestellt - klemmend untergreift. Man erkennt anhand der Fig. 1 u. 2 deutlich, daß in dieser Position des Verlängerungsstückes 10 ein Zurückschwenken des Bügels 5 gesperrt, also nicht möglich ist.In order to hold the two formwork panels 2 together in an aligned position and, if necessary, to align them somewhat when bracing, the clamping bracket 5 in the position of use grips the surfaces 9 of the edge webs 4 facing away from one another, at least in regions, in a form-fitting manner. Furthermore, in this position of use, for a good alignment, the free edges 4a of the edge webs 4 rest on the corresponding inside of the frame. For bracing the free bracket arm 7 on the rod 8, an extension piece 10 is provided which is displaceable approximately in the direction of the free bracket end and which, after being displaced, engages under the rod 8 - as shown in the drawing - in a clamping manner. It can be seen from FIGS. 1 u. 2 clearly shows that in this position of the extension piece 10, pivoting back of the bracket 5 is blocked, that is to say is not possible.

Das Verlängerungsstück 10 ist dabei an einem Vorsprung 11 an der Außenseite des freien Bügelarmes 7 angeordnet, welcher Vorsprung 11 an dem Stab 8 vorbeischwenkbar ist und auch in Gebrauchsstellung einen Abstand zu dem Stab 8 hat, den das Verlängerungsstück 10 überbrückt. Im Ausführungsbeispiel ist dabei der freie Bügelarm 7 zwischen dem Randsteg 4 und dem Verankerungsstab 8 in seine Gebrauchsstellung einschwenkbar, d.h. er wird nicht über die dem Randsteg 4 abgewandte Seite des Stabes 8 geschwenkt und dort eingehängt.The extension piece 10 is arranged on a projection 11 on the outside of the free bracket arm 7, which projection 11 can be pivoted past the rod 8 and is also at a distance from the rod 8 in the use position, which the extension piece 10 bridges. In the exemplary embodiment, the free bracket arm 7 can be swiveled into its use position between the edge web 4 and the anchoring rod 8, i.e. it is not pivoted over the side of the rod 8 facing away from the edge web 4 and hung there.

Das verschiebbare Verlängerungsstück 10 verläuft mit seiner dem Stab 8 zugewandten Oberseite 10a schräg zu seiner Verschieberichtung und Führung, wobei diese Schrägung entgegen der Richtung ansteigt, in welcher das Verlängerungsstück 10 zum Erreichen der in Figur dargestellten Verriegelungsposition verschoben wird. Somit ergibt sich nach einem ersten Berührkontakt dieser Oberseite 10a mit der entsprechenden Unterseite 8a des Stabes 8 bei der weiteren Verschiebung des Verlängerungsstückes 10 in erwünschter Weise eine Verklemmung und Andrückung des Bügels 5 an beide Randstege 4.The displaceable extension piece 10 extends with its upper side 10a facing the rod 8 obliquely to its direction of displacement and guidance, this inclination increasing against the direction in which the extension piece 10 is displaced to reach the locking position shown in the figure. This results after a first contact of this upper side 10a with the corresponding lower side 8a of the rod 8 in the further one Displacement of the extension piece 10 in the desired manner a jamming and pressing the bracket 5 against both edge webs 4th

Um dabei ausreichend hohe Kräfte übertragen zu können, ist das Verlängerungsstück 10 auf einer etwa parallel zur Stabunterseite 8a verlaufenden, gestrichelt dargestellten Abstützung 12 verschiebbar und im Hinblick auf die Schrägung der Oberseite 10a praktisch als Spannkeil ausgebildet. Zusätzlich zu dieser Führung an der Abstützung 12 kann das Verlängerungsstück mittels eines Querstiftes 13 außerdem noch unverlierbar in einem Langschlitz 14 eines Flansches oder einer Nutenwand od.dgl. an der Bügelaußenseite geführt sein, wie man es im Ausführungsbeispiel deutlich erkennt.In order to be able to transmit sufficiently high forces, the extension piece 10 is displaceable on a support 12, which is shown in dashed lines and runs approximately parallel to the underside 8a of the rod, and is designed practically as a wedge with regard to the inclination of the top 10a. In addition to this guide on the support 12, the extension piece by means of a cross pin 13 can also be captive or the like in an elongated slot 14 of a flange or a groove wall. be guided on the outside of the bracket, as can be clearly seen in the exemplary embodiment.

Im Ausführungsbeispiel hat das Verlängerungsstück 10 an seinem dem Befestigungsende abgewandten Ende einen gegenüber der Führung 12 und dem Bügelarm 7 bzw. dem Vorsprung 11 vorstehenden eigenen Vorsprung 15 für den Angriff eines Werkzeuges, z.B. eines Hammers. Dabei kann mit diesem Werkzeug entweder dieses Verlängerungsstück 10 in seiner Gebrauchsstellung festgeschlagen oder bei entgegengesetzter Beaufschlagung des Vorsprunges 15 gelockert werden. Praktisch ergibt sich dadurch ein Verlängerungsstück 10, welches wie ein Schub- und Zugriegel bedient werden kann und auch so wirkt, zusätzlich aber auch noch die schon beschriebene Keilwirkung hat.In the exemplary embodiment, the extension piece 10 has, at its end facing away from the fastening end, a projection 15 of its own that protrudes from the guide 12 and the bracket arm 7 or the projection 11 for the attack of a tool, e.g. a hammer. This tool can either be used to fix this extension piece 10 in its position of use or to loosen it when the projection 15 is acted upon in the opposite direction. In practice, this results in an extension piece 10, which can be operated and acts like a push and pull bolt, but additionally also has the wedge effect already described.

Es wurde schon erwähnt, daß die Innenkontur des Klemmbügels 5 der Außenkontur der beiden aneinanderliegenden Randstege 4 weitgehend entspricht, wobei im Ausführungsbeispiel allerdings der freie Bügelarm 7 nahe seinem freien Ende einen in das Bügelinnere gerichteten Anschlagvorsprung 16 als Anschlag gegen den stabseitigen Randsteg hat. Die restliche Oberseite 9 dieses Randsteges 4 bleibt also frei, so daß Maßunterschiede und Toleranzen sich nicht negativ auswirken, sondern wirklich die am weitesten beabstandeten Bügelbereiche jeweils an den Oberseiten 9 der Randstege 4 zur Anlage kommen und unter bestmöglichen Hebelarmen die gewünschte Verspannung und Verbindung herstellen. Dabei verlaufen die beiden Randstege 4 an ihren ihren Berührflächen abgewandten Oberseiten 9 von der Schalhaut 2 zu den freien Rändern 4a im Querschnitt schräg und bilden zusammen etwa ein Trapez; demgemäß ist auch die Bügelöffnung im wesentlichen trapezförmig. Somit läßt sich selbst bei noch etwas beabstandeten Randstegen 4 der Bügel 5 in seine Gebrauchsstellung schwenken und kann dabei bereits die beiden Randstege 4 einander annähern und auch ausrichten.It has already been mentioned that the inner contour of the clamping bracket 5 largely corresponds to the outer contour of the two adjoining edge webs 4, although in the exemplary embodiment the free bracket arm 7 near its free end has a stop projection 16 directed into the interior of the bracket as a stop against the rod-side edge web. The rest of Top 9 of this edge web 4 thus remains free, so that dimensional differences and tolerances do not have a negative effect, but rather the most widely spaced bracket areas come into contact with the top sides 9 of the edge webs 4 and produce the desired tensioning and connection with the best possible lever arms. The two edge webs 4 run obliquely in cross-section on their upper sides 9 facing away from their contact surfaces from the formlining 2 to the free edges 4a and together form approximately a trapezoid; accordingly, the bow opening is also substantially trapezoidal. Thus, the bracket 5 can be pivoted into its position of use even when the edge webs 4 are still somewhat spaced and can already bring the two edge webs 4 closer to one another and also align them.

Um bei geöffnetem Bügel 5 diesen völlig frei schwenken zu können, ihn aber in Schließstellung auch an dem lagerseitigen Randsteg 4 fest zur Anlage zu bringen, ist das Lagerauge 18 des Schwenklagers 19 als Exzenter ausgebildet und hat in der strichpunktiert dargestellten Offenstellung des Bügels 5 einen etwa dem Doppelten der Exzentrizität entsprechenden lichten Abstand von dem ihm benachbarten Randsteg 4, während es in Schließstellung mit der Bügelinnenseite an dem Randsteg 4 angedrückt ist.In order to be able to pivot it completely freely when the bracket 5 is open, but also to bring it firmly into contact with the bearing-side edge web 4 in the closed position, the bearing eye 18 of the pivot bearing 19 is designed as an eccentric and has an approximately in the open position of the bracket 5 shown in phantom twice the eccentricity of the clear distance from the adjacent edge web 4, while in the closed position it is pressed against the edge web 4 with the inside of the bracket.

Der Stab 8 hat für eine gute Anlage des Verlängerungsstükkes 10 eine im querschnitt ebene Unterseite 8a und ist im Ausführungsbeispiel als Vierkantrohr ausgebildet, wobei der querschnitt seiner Unterseite etwa parallel zur Schieberichtung des Verlängerungsstückes 10 orientiert ist. Dabei erkennt man anhand der Orientierung des Langschlitzes 14 und der Führungs-Abstützung 12, daß die Schieberichtung des Verlängerungsstückes 10 unter einem weniger spitzen Winkel zu einer Senkrechten zur Schalhaut 3 als der freie Bügelarm 7 und seiner an dem Randsteg 4 anlegbare Innenseite liegt. Dies erlaubt nicht nur das klemmende Anpressen des Bügelarmes 7 an dem von ihm beaufschlagten Randsteg 4, sondern ergibt in erwünschter Weise in der dargestellten Gebrauchsstellung gleichzeitig eine Verriegelung des Bügels 5 gegen ein ungewolltes Aufschwenken.The rod 8 has for a good contact of the extension piece 10 a cross-sectionally flat underside 8a and is designed in the exemplary embodiment as a square tube, the cross section of its underside being oriented approximately parallel to the sliding direction of the extension piece 10. It can be seen from the orientation of the elongated slot 14 and the guide support 12 that the sliding direction of the extension piece 10 at a less acute angle to a perpendicular to the formlining 3 than the free bracket arm 7 and its inner side which can be placed on the edge web 4 lies. This not only allows the clamp arm 7 to be clamped against the edge web 4 acted upon by it, but also, in the desired position of use, results in a locking of the bracket 5 against unwanted swinging open.

Die Schwenkachse 6 für den Bügel 5 und auch der Befestigungsstab 8 können in vorteilhafter und zweckmäßiger Weise zwischen rechtwinklig zu den zu verbindenden Randstegen 4 angeordneten Stegen 20 der jeweiligen Schaltafel 2 verlaufen und an diesen Stegen 20 verankert sein. Somit ergibt sich insgesamt eine unverlierbare Befestigungsvorrichtung, wobei selbstverständlich bei relativ großen Abständen der Stege 20 auf einer Achse 6 auch mehrere Bügel 5 sich mit Abstand zueinander befinden können.The pivot axis 6 for the bracket 5 and also the fastening rod 8 can run in an advantageous and expedient manner between webs 20 of the respective formwork panel 2 arranged at right angles to the edge webs 4 to be connected and can be anchored to these webs 20. Overall, this results in a captive fastening device, wherein, of course, with relatively large distances between the webs 20 on an axis 6, a plurality of brackets 5 can also be located at a distance from one another.

Die Bedienung dieser Befestigungsvorrichtung 1 ist äußerst einfach, weil nach dem Zusammenstellen der beiden Schaltafeln 2 lediglich der oder die Bügel 5 in Schließstellung geschwenkt und durch das Verschieben des Verlängerungsstückes 10 verankert werden müssen, um eine Verbindung der beiden Schaltafeln 2 mit hohen Kräften zu erreichen. Ebenso einfach ist das Öffnen dieser Vorrichtung und somit das Ausschalen.The operation of this fastening device 1 is extremely simple, because after the two formwork panels 2 have been put together, only the bracket or brackets 5 have to be pivoted into the closed position and anchored by moving the extension piece 10 in order to achieve a connection of the two formwork panels 2 with high forces. Opening this device and thus stripping it is just as easy.

Ein insbesondere bezüglich des Klemmbügels 5, aber auch des Befestigungsstabes 8 abgewandeltes Ausführungsbeispiel ist in den Figuren 2 bis 5 dargestellt. Trotz der dabei vorgesehenen Abänderungen und Abwandlungen erhalten dabei die dem vorbeschriebenen Ausführungsbeispiel entsprechenden Teile übereinstimmende Bezugszahlen.An exemplary embodiment modified in particular with regard to the clamping bracket 5 but also the fastening rod 8 is shown in FIGS. 2 to 5. Despite the proposed changes and modifications, the parts corresponding to the previously described exemplary embodiment are given the same reference numbers.

In diesem zweiten Ausführungsbeispiel hat der KLemmbügel 5 für seine Schwenkachse 6 als Schwenklager 19 eine Durchtrittsöffnung 19a, deren Randverlauf eine wenigstens teilweise verschließbare Unterbrechung 21 mit solcher Länge aufweist, die dem Querschnitt der Schwenkachse 6 entspricht. Wird die Unterbrechung 21 also geöffnet, kann der Klemmbügel 5 von der Schwenkachse 6 abgenommen werden, indem er mit seiner Unterbrechung 21 quer zum Verlauf der Schwenkachse 6 von dieser wegbewegt wird.In this second exemplary embodiment, the clamping bracket 5 has a through opening 19a for its pivot axis 6 as pivot bearing 19, the edge profile of which has an interruption 21 which can be at least partially closed and has a length which corresponds to the cross section of the pivot axis 6. If the interruption 21 is thus opened, the clamping bracket 5 can be removed from the pivot axis 6 by moving it with its interruption 21 transversely to the course of the pivot axis 6.

Dabei ist die Durchtrittsöffnung 19a für die Schwenkachse 6 eine in Gebrauchsstellung des Klemmbügels 5 quer zur Schalhaut 3, im Ausführungsbeispiel etwa rechtwinklig zur Schalhaut 3 von dieser wegverlaufende Langlochung und die Unterbrechung 21 des Randes dieses Langloches befindet sich nahe dem der Schalhaut 3 abgewandten Ende dieser Langlochung. Man erkennt in Fig. 2 und 3, daß die Unterbrechung dabei noch im Bereich der Längswand des Langloches und nicht etwa unmittelbar an deren Ende angeordnet ist und zwar auf der dem eigentlichen Klemmbügel abgewandten Seite. Somit kann der Klemmbügel nach seinem Aufschwenken leicht an der Rückseite der Schaltafel 2 von dieser wegbewegt werden,wobei dann die Schwenkachse 6 durch die Unterbrechung 21 freigegeben ist.The through opening 19a for the pivot axis 6 is a in the use position of the clamping bracket 5 transverse to the formlining 3, in the exemplary embodiment approximately at right angles to the formwork 3 from this elongated perforation and the interruption 21 of the edge of this elongated hole is near the end of this elongated hole facing away from the formwork 3 . 2 and 3 that the interruption is still arranged in the region of the longitudinal wall of the elongated hole and not approximately directly at its end, on the side facing away from the actual clamping bracket. Thus, the clamping bracket can be easily moved away from the rear of the formwork panel 2 after it has been swung open, the pivot axis 6 then being released by the interruption 21.

Der Verschluß für die Unterbrechung 21 ist im Ausführungsbeispiel durch einen gegen eine Rückstellkraft bzw. eine Rückstellfeder 22 versenkbaren Stift 23 gebildet. Es könnte aber auch ähnlich einer Öse an einem Schmuck-Verschluß ein federbelasteter Bügel die Unterbrechung überbrücken oder es könnte ein quer zu der Unterbrechung ausfedernder Wandbereich ähnlich wie bei einem Karabinerhaken vorgesehen sein. Da jedoch der Verschluß nicht die gesamte Unterberechung 21 überbrücken muß, genügt ein in die Unterbrechung 21 ragender und aus ihr zurückschiebbarer Stift 23.In the exemplary embodiment, the closure for the interruption 21 is formed by a pin 23 which can be lowered against a restoring force or a restoring spring 22. However, a spring-loaded clip could also bridge the interruption, similar to an eyelet on a jewelry clasp, or a wall area resiliently extending transversely to the interruption could be provided, similarly to a snap hook. However, since the closure does not have to bridge the entire sub-calculation 21, a pin 23 which projects into the interruption 21 and can be pushed back out of it is sufficient.

In diesem Ausführungsbeispiel sind die Schwenkachse 6 und der von dem verschiebbaren Verlängerungs- oder Verriegelungsstück 10 zu untergreifende Befestigungsstab 8 auf gleicher Höhe und in übereinstimmendem Abstand relativ zu den Randstegen 4 der zu verbindenden Schaltafeln 2 angeordnet. Dabei haben sie einen übereinstimmenden, im Ausführungsbeispiel kreisrunden Querschnitt, so daß die Schwenkachse 6 und der Stab 8 zweier mit dem Klemmbügel 5 verbundener Schaltafeln spiegelsymmetrisch zu einer durch die Berührungsfuge der beiden Schaltafeln zwischen deren Randstegen 4 verlaufende Ebene angeordnet sind. Da der Klemmbügel 5 durch die vorbeschriebene öffenbare Unterbrechung 21 seines Langloches trotz einer in der Regel unverlierbaren Halterung demontiert werden kann, können also Schwenkachse 6 und Befestigungsstab 8 gewissermaßen gegeneinander ausgetauscht werden. Während bei dem Ausführungsbeispiel nach Fig. 1 beim Zusammenfügen der Schaltafeln immer darauf geachtet werden muß, daß an der zu verbindenden Fuge auf der einen Seite eine Schwenkachse und auf der gegenüberliegenden Seite ein Befestigungsstab zu liegen kommen, braucht dies bei diesem Ausführungsbeispiel nicht mehr berücksichtigt zu werden.In this exemplary embodiment, the pivot axis 6 and the fastening rod 8 to be gripped by the displaceable extension or locking piece 10 are arranged at the same height and at a corresponding distance relative to the edge webs 4 of the formwork panels 2 to be connected. They have a matching cross section, which is circular in the exemplary embodiment, so that the pivot axis 6 and the rod 8 of two formwork panels connected to the clamping bracket 5 are arranged mirror-symmetrically to a plane running through the contact joint of the two formwork panels between their edge webs 4. Since the clamping bracket 5 can be dismantled by the above-described openable interruption 21 of its elongated hole in spite of a generally captive holder, pivot axis 6 and fastening rod 8 can be exchanged with one another to a certain extent. While in the embodiment according to FIG. 1, when assembling the formwork panels, care must always be taken to ensure that a swivel axis and a fastening rod come to rest on the joint to be connected on the one side, this embodiment no longer needs to be taken into account will.

In Fig. 4 erkennt man, daß Schwenkachsen 6 und/oder Stäbe 8 entlang allen vier Randstegen 4 einer rechteckigen Schaltafel 2 jeweils mit übereinstimmendem Abstand vorgesehen sind. Somit kann auch auf eine Schalwand aus mit ihren längeren Rändern vertikal stehenden Schaltafeln 2 zur Aufstockung eine Schaltafel befestigt werden, die demgegenüber um 90° gedreht ist, so daß sie mit ihrer längeren Seite auf den kürzeren Seiten der erstgenannten Schaltafeln zu liegen kommt. Auch an dieser Stelle ist dann eine Verbindung mit einem Klemmbügel 5 durchführbar.In Fig. 4 it can be seen that pivot axes 6 and / or rods 8 are provided along all four edge webs 4 of a rectangular formwork panel 2 each with the same distance. Thus, a formwork panel can also be fastened to a formwork wall from vertical formwork panels 2 with its longer edges, which, on the other hand, is rotated by 90 ° so that its longer side comes to rest on the shorter sides of the former formwork panels. A connection to a clamping bracket 5 can then also be carried out at this point.

Selbstverständlich erlauben diese Schaltafeln auch einen gegenseitigen Höhenversatz, weil die Klemmbügel jeweils an beliebigen Stellen der Schwenkachsen 6 und Befestigungsstäbe 8 angreifen können.Of course, these formwork panels also allow a mutual height offset, because the clamping bracket each can attack at any point of the pivot axes 6 and 8 mounting rods.

In Fig. 4 erkennt man ferner, daß die parallel zu den kürzeren Rändern und Randstegen der rechteckigen Schaltafel 2 verlaufenden Schwenkachsen 6 und Stäbe 8 jeweils stumpf auf die rechtwinklig zu ihnen angeordneten Schwenkachsen 6 und Stäbe 8 der anderen Längsseiten der Schaltafel 2 stoßen und vorzugsweise mit ihnen verbunden, z.B. verschweißt sind. Es ergibt sich dadurch eine zustäzliche Aussteifung der gesamten Schaltafel 2, so daß auch die über die Klemmbügel 5 auftretenden Kräfte gut übernommen und in die Aussteifungen und Stege der Schaltafeln 2 eingeleitet werden können. Dabei zeigt Fig. 4 ferner, daß die Schwenkachsen 6 und Stäbe 8 jeweils zwischen Aussteifungsrippen 20 der Schaltafel 2 angeordnet sind und diese dabei evtl. sogar quer zu ihrem Verlauf durchsetzen und daß die parallel zu solchen Aussteifungsrippen 20 und parallel zu den kürzeren Rändern einer Schaltafel 2 verlaufenden Stäbe 8 und Schwenkachsen 6 wenigstens eine Abstützung 24, im Ausführungsbeispiel jeweils drei solche Abstützungen 24 gegenüber dem Randsteg 4 haben. Auch eine Abstützung 24 gegenüber einer Aussteifungsrippe 20 wäre möglich aber, wie Fig. 4 zeigt, entsprechend länger auszubilden.In Fig. 4 it can also be seen that the pivot axes 6 and rods 8 running parallel to the shorter edges and edge webs of the rectangular formwork panel 2 each abut the pivot axes 6 and rods 8 of the other longitudinal sides of the formwork panel 2 arranged at right angles to them and preferably with connected to them, e.g. are welded. This results in an additional stiffening of the entire formwork panel 2, so that the forces occurring via the clamping bracket 5 can be well accepted and introduced into the stiffeners and webs of the formwork panels 2. Fig. 4 also shows that the pivot axes 6 and rods 8 are each arranged between stiffening ribs 20 of the formwork panel 2 and possibly even pass through transversely to their course and that the parallel to such stiffening ribs 20 and parallel to the shorter edges of a formwork panel 2 extending rods 8 and pivot axes 6 have at least one support 24, in the exemplary embodiment three such supports 24 each with respect to the edge web 4. A support 24 with respect to a stiffening rib 20 would also be possible, however, as shown in FIG. 4, to be made correspondingly longer.

Insgesamt ergibt sich eine Schaltafel 2, die für die Verbindung mit einer Nachbarschaltafel an einem beliebigen Rand und mit beliebigem Höhenversatz sie zusätzlich aussteifende Stäbe und Achsen aufweist, an denen einfach bedienbare und leicht zu verriegelnde und zu verankernde Klemmbügel 5 angreifen, die beim Ausführungsbeispiel gemäß den Figuren 2 und 3 trotz ihrer unverlierbaren Halterung auch umsetzbar sind, so daß die Montage der Schaltafeln erleichtert wird.Overall, there is a formwork panel 2 which, for the connection to a neighboring formwork panel at any edge and with any height offset, additionally has stiffening rods and axles on which easy-to-use and easily lockable and anchored clamping brackets 5 act, which in the exemplary embodiment according to FIGS Figures 2 and 3 can also be implemented despite their captive bracket, so that the assembly of the formwork panels is facilitated.
