Description

Die Erfindung betrifft eine Schalungszwinge, insbesondere zur Schalung eines Unterzugs einer Betondecke, mit einem Querträger und als Stützböcke zum Abstützen einer Seitenschalung des Unterzugs dienenden Zwingenschenkeln, von denen mindestens einer in Längsrichtung des Querträgers verstellbar ist, und mit mindestens einem Spannstab, der an dem Querträger befestigbar ist.The invention relates to a formwork clamp, in particular for formwork of a beam of a concrete ceiling, with a cross member and as support stands for supporting a side form of the beam serving clamp legs, of which at least one is adjustable in the longitudinal direction of the cross member, and with at least one tie rod which is attached to the cross member is attachable.

Eine bekannte Schalungszwinge der Firma Assco, 7958 Laupheim 5, weist einen Querträger mit Querbohrungen, zwei Stützböcke und zwei Spannstäbe mit querverlaufenden Durchstecköffnungen auf. Zum Festlegen der beiden Spannstäbe an dem Querträger wird jeweils ein Bolzen durch durch eine Querbohrung im Querträger und durch die Durchstecköffnung im Spannstabende gesteckt. Der Bolzen wird beispielsweise mittels eines Federsteckers gesichert. Eine Wirbelmutter auf dem Spannstab hält den Stützbock in Längsrichtung des Querträgers fest.A known formwork clamp from Assco, 7958 Laupheim 5, has a cross member with cross bores, two support frames and two tie rods with transverse through openings. To fix the two tie rods to the cross member, a bolt is inserted through a cross hole in the cross member and through the through hole in the end of the tie rod. The bolt is secured, for example, by means of a spring pin. A swivel nut on the tension rod holds the support frame in the longitudinal direction of the cross member.

Diese bekannte Schalungszwinge hat den Nachteil, daß das Befestigungsauge des Spannstabs fluchtend mit der Querbohrung im Querträger ausgerichtet und gehalten werden muß, damit der Bolzen hindurchgesteckt werden kann. Anschließend muß der Bolzen gesichert werden. Dies bedingt erheblichen Handhabungsaufwand. Außerdem können Verschmutzungen, beispielsweise durch Betonreste, in den Querbohrungen im Querträger und in den Durchstecköffnungen der Spannstäbe das Durchstecken des Bolzens verhindern.This known formwork clamp has the disadvantage that the fastening eye of the tie rod must be aligned and held in alignment with the transverse bore in the cross member so that the bolt can be inserted through it. Then the bolt must be secured. This requires considerable handling effort. In addition, contamination, for example from concrete residues, in the cross bores in the cross member and in the push-through openings of the tie rods can prevent the bolt from being pushed through.

Damit sich die Schalung der Unterseite des zu schalenden Unterzugs beim Einfüllen von Beton nicht durchbiegt, muß die Schalung in ausreichend kleinen Abständen unterstützt werden. Dazu kann entweder eine entsprechend große Anzahl von Querträgern verwendet werden. Dabei sind schwere Querträger von Nachteil, da sie schlecht handhabbar sind. Oder es werden Längsträger, beispielsweise herkömmliche Träger aus Holz, auf die Querträger aufgelegt. Es werden dann weniger Querträger in größerm Abstand voneinander benötigt, da die Längsträger ein Durchbiegen der Schalung der Unterseite des Unterzugs verhindern. Durch die auf die Querträger aufgelegten Längsträger ergibt sich ein Abstand zwischen der Unterseite des zu schalenden Unterzugs und den Querträgern. Die die Stützböcke bildenden Zwingenschenkel müssen höher und stabiler ausgeführt sein, um die Seitenschalung abstützen zu können.So that the formwork on the underside of the beam to be formwork does not bend when pouring concrete, the formwork must be supported at sufficiently small intervals. Either a correspondingly large number of cross beams can be used for this. Heavy cross members are disadvantageous because they are difficult to handle. Or longitudinal members, for example conventional wooden members, are placed on the cross members. Less crossbeams are then required at a greater distance from one another, since the longitudinal beams prevent the formwork on the underside of the beam from bending. The longitudinal beams placed on the cross beams result in a Distance between the underside of the beam to be formwork and the cross beams. The clamp legs that form the trestles must be higher and more stable in order to support the side formwork.

Aufgabe der Erfindung ist, eine einfach handhabbare Schalungszwinge zur Verfügung zu stellen.The object of the invention is to provide an easy-to-use formwork clamp.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Spannstab an dem Querträger einhakbar ist.This object is achieved in that the tie rod can be hooked onto the cross member.

Das bloße Einhaken ist ein sehr einfacher Vorgang. Die Befestigung durch einen Haken reicht aus, weil der Stützbock nur in einer Richtung, z. B. bei Unterzugschalungen in Richtung der Aufweitung des Zwingenmaules, beim Eingießen von Beton beansprucht wird.Simply hooking it up is a very simple process. The attachment by a hook is sufficient because the support frame only in one direction, e.g. B. in joist formwork in the direction of widening the clamp mouth when pouring concrete is claimed.

Bei einer Ausführungsform der Erfindung weist der Querträger eine Spannschiene auf, in die der Spannstab einhakbar ist. Dies hat den Vorteil, daß die Spannschiene einen Großteil der aufzubringenden Spannkraft aufnimmt. Dadurch kann als Querträger ein herkömmlicher Holzträger verwendet werden; dessen Festigkeit ausreichend ist. Lediglich die Spannschiene ist aus einem Werkstoff höherer Festigkeit zu fertigen, beispielsweise aus Metall, insbesondere aus Stahl. Das Gewicht der erfindungsgemäßen Schalungszwinge ist relativ gering. Zusätzlicher Vorteil der erfindungsgemäßen Schalungszwinge ist, daß die Spannschiene, und damit auch der Stützbock auch an einem geeigneten, für eine Schalung ohnehin benötigten Holz- oder sonstigen Träger befestigt werden kann. Ein speziell ausgebildeter Querträger für die Schalungszwinge entfällt. Dadurch ist die erfindungsgemäße Schalungszwinge einfach in verschiedene Schalungen integrierbar.In one embodiment of the invention, the cross member has a tensioning rail into which the tensioning rod can be hooked. This has the advantage that the tensioning rail absorbs a large part of the tensioning force to be applied. As a result, a conventional wooden beam can be used as a cross beam; the strength of which is sufficient. Only the tensioning rail is to be manufactured from a material of higher strength, for example from metal, in particular from steel. The weight of the formwork clamp according to the invention is relatively low. An additional advantage of the formwork clamp according to the invention is that the tensioning rail, and thus also the support frame, can also be fastened to a suitable wooden or other support that is required for formwork. A specially designed cross member for the formwork clamp is not required. As a result, the formwork clamp according to the invention can be easily integrated into different formwork.

Weiterer Vorteil der erfindungsgemäßen Schalungszwinge ist, daß der Spannstab einfach mit einer Hand in die Spannschiene einhakbar ist. Umständliches Ausrichten des Spannstabs zum Befestigen am Querträger entfällt; ebenso entfallen zusätzliche Befestigungs- und Sicherungsteile.Another advantage of the formwork clamp according to the invention is that the tensioning rod can be easily hooked into the tensioning rail with one hand. There is no need to laboriously align the tension rod to attach it to the crossmember; additional fastening and securing parts are also omitted.

Eine Ausführungsform der Erfindung weist zwei in Längsrichtung des Querträgers verstellbare Stützböcke zum Abstützen beider Seitenschalungen eines Unterzugs auf. Diese Ausführungsform der Erfindung hat den Vorteil, daß die Position beider Seitenschalungen einstellbar ist. Dies kann notwendig sein, wenn als Querträger ein Träger genutzt wird, der Bestandteil der übrigen Schalung ist. Auch wenn die Schalung des Unterzugs nicht am Boden vormontiert wird, sondern auf einer Stützkonstruktion zusammengesezt wird, ist vorteilhaft, wenn beide Stützböcke verstellbar sind.One embodiment of the invention has two support trestles which can be adjusted in the longitudinal direction of the cross member to support both side formwork of a beam. This embodiment of the invention has the advantage that the position of both side molds is adjustable. This may be necessary if a girder is used as a cross girder that is part of the rest of the formwork. Even if the formwork of the joist is not pre-assembled on the floor, but is put together on a support structure, it is advantageous if both support frames are adjustable.

Bei einer Ausführungsform der Erfindung ist jeder Spannstab an mehreren Stellen längs der Spannschiene einhakbar. Dadurch lassen sich die Stützböcke schnell innerhalb eines großen Bereichs einstellen. Bei Verwendung eines Gewindestabs als Spannstab sind die Stützböcke stufenlos einstellbar.In one embodiment of the invention, each tensioning rod can be hooked in several places along the tensioning rail. This means that the support frames can be quickly adjusted within a large range. When using a threaded rod as a tensioning rod, the support frames are infinitely adjustable.

Bei einer Ausführungsform der Erfindung weist die Spannschiene Aussparungen zum Einhaken des Spannstabs auf. Diese Aussparungen können jede geeignete Form aufweisen, sie können beispielsweise durch Fräsen hergestellt sein. Eine solche Spannschiene läßt sich einfach herstellen.In one embodiment of the invention, the tensioning rail has cutouts for hooking in the tensioning rod. These recesses can have any suitable shape, for example they can be produced by milling. Such a tensioning rail can be easily manufactured.

Bei einer Ausführungsform der Erfindung ist das Ende des Spannstabs hakenförmig ausgebildet. Ein solcher Spannstab ist einfach herstellbar und läßt sich in verschiedene Aussparungen oder Hinterschneidungen der Spannschiene einhaken, beispielsweise auch in kreisrunde Bohrungen.In one embodiment of the invention, the end of the tension rod is hook-shaped. Such a tie rod is simple producible and can be hooked into various recesses or undercuts of the tensioning rail, for example also in circular bores.

Bei einer anderen Ausführungsform der Erfindung ist ein Ende des Spannstabs T-förmig ausgebildet. Ein solcher Spannstab kann in geeignet geformte Aussparungen der Spannschiene eingeführt und durch Drehen um 90° um seine Längsachse gegen Herausziehen aus der Spannschiene gesichert werden. Ein solcher Spannstab kann, auch wenn er unbelastet ist, nicht aus der Aussparung austreten, solange er nicht um 90° um seine Längsachse gedreht wird.In another embodiment of the invention, one end of the tension rod is T-shaped. Such a tensioning rod can be inserted into suitably shaped recesses in the tensioning rail and secured against being pulled out of the tensioning rail by rotating through 90 ° about its longitudinal axis. Such a tie rod, even if it is not loaded, cannot emerge from the recess as long as it is not rotated through 90 ° about its longitudinal axis.

Bei einer bevorzugten Ausführungsform der Erfindung ist der Querträger ein aus zwei Trägern gebildeter Doppelträger. Als Träger eignen sich herkömmliche Holzträger. Hierdurch läßt sich eine statisch günstige Konstruktion der Schalungszwinge erzielen, wenn die Spannschiene zwischen den beiden Trägern angeordnet wird und die Spannstäbe zwischen die beiden Träger greifen. Darüberhinaus kann der Doppelträger als Führung für die Stützböcke dienen.In a preferred embodiment of the invention, the cross member is a double member formed from two members. Conventional wooden supports are suitable as supports. This allows a structurally favorable construction of the formwork clamp to be achieved if the tensioning rail is arranged between the two beams and the tensioning rods engage between the two beams. In addition, the double beam can serve as a guide for the trestles.

Bei einer Weiterbildung dieser Ausführungsform sind die beiden Träger durch Stege miteinander verbunden, die als Widerlager für den Spannstab dienen. Bei einer anderen Ausführungsform sind die beiden Träger durch die Spannschiene zu einem Doppelträger verbunden. Dadurch ergibt sich eine Einheit aus Spannschiene und Querträger. Die beiden Träger können noch an weiteren Stellen mit Abstand zueinander aneinander befestigt sein.In a further development of this embodiment, the two supports are connected to one another by webs which serve as abutments for the tensioning rod. In another embodiment, the two beams are connected to a double beam by the tensioning rail. This results in a unit consisting of a tensioning rail and cross member. The two supports can be fastened to one another at further points at a distance from one another.

Bei einer bevorzugten Ausführungsform der Erfindung ist an einer Spannschiene eine weitere Spannschiene befestigbar. Dadurch kann die Spannschiene beliebig verlängert werden und dementsprechend ist der Abstand zweier Stützböcke einer Schalungszwinge voneinander beliebig groß wählbar. Auch bei dieser Ausführungsform nehmen die aneinander befestigten Spannschienen einen Großteil der aufzubringenden Spannkraft auf. Die Belastung des Querträgers ist wesentlich verringert.In a preferred embodiment of the invention, a further clamping rail can be fastened to a clamping rail. Thereby the tensioning rail can be extended as required and accordingly the distance between two support frames of a formwork clamp can be chosen as large as required. In this embodiment, too, the clamping rails fastened to one another absorb a large part of the clamping force to be applied. The load on the cross member is significantly reduced.

Bei einer Weiterbildung dieser Ausführungsform sind die Spannschienen miteinander verhakbar. Solche Spannschienen sind einfach und ohne zusätzliche Verbindungsmittel aneinander zu befestigen.In a further development of this embodiment, the tensioning rails can be hooked together. Such tensioning rails are easy to attach to one another without additional connecting means.

Bei einer Ausführungsform der Erfindung ist der Spannstab in einen Anker einhakbar. Ein solcher Anker kann in einen bereits fertiggestellten Boden oder eine Decke einbetoniert sein. In diesem Fall entfallen Querträger und Spannschiene.

Der in Fig. 1 gezeigte Stützbock 1 besteht im wesentlichen aus zwei L-Profilstäben 2, 3, einem zu diesen senkrecht stehenden U-Profilstab 4 und zwei Stützstreben 5, 6. Die beiden L-Profilstäbe 2, 3 verlaufen parallel im Abstand zueinander. Die beiden L-Profilstäbe 2, 3 sind so zueinander ausgerichtet, daß zwei Schenkel in einer Ebene liegen und die beiden anderen Schenkel einander zugewandt sind, parallel zueinander verlaufen und nach unten weisen. Diese beiden Schenkel sind zur Führung vorgesehen. Der U-Profilstab 4 ist an einem Ende der beiden L-Profilstäbe 2, 3 senkrecht nach oben stehend befestigt. Die konkave Seite des U-Profilstabs 4 ist den beiden L-Profilstäben 2, 3 abgewandt. Die beiden Stützstreben 5, 6 verlaufen parallel mit Abstand zueinander zur Aussteifung des Winkels zwischen je einem L-Profilstab 2, 3 und dem U-Profilstab 4. Die Stützstreben 5, 6 bilden zusammen mit den Profilstäben 2, 3, 4 Stützdreiecke.The support bracket 1 shown in Fig. 1 consists essentially of two L-shaped bars 2, 3, a U-shaped bar 4 perpendicular to these and two supporting struts 5, 6. The two L-shaped bars 2, 3 run parallel to one another at a distance. The two L-profile bars 2, 3 are aligned with one another in such a way that two legs lie in one plane and the other two legs face one another, run parallel to one another and point downward. These two legs are intended for guidance. The U-section bar 4 is attached to one end of the two L-section bars 2, 3 standing vertically upwards. The concave side of the U-shaped bar 4 faces away from the two L-shaped bars 2, 3. The two support struts 5, 6 run parallel to each other at a distance from each other for stiffening the angle between an L-profile bar 2, 3 and the U-profile bar 4. The support struts 5, 6 together with the profile bars 2, 3, 4 form support triangles.

Ein Spannstab 7 befindet sich in der Mittelebene des Stützbocks 1; er ragt durch den Zwischenraum zwischen den beiden L-Profilstäben 2, 3 und zwischen den beiden Stützstreben 5, 6 des Stützbocks 1. Der Spannstab 7 weist ein Gewinde 8 auf, insbesondere ein sogenanntes Dywidag-Gewinde. Sein unteres Ende befindet sich unterhalb des Stützbocks 1, es ist mit einem Haken 9 versehen. Zum Spannen ist eine Wirbelmutter 10 auf den Spannstab 7 aufgeschraubt. Ihre Anlagefläche übergreift die beiden Stützstreben 5, 6 des Stützbocks 1 und stützt sich gegen diese ab.A tie rod 7 is located in the central plane of the support frame 1; it projects through the space between the two L-shaped bars 2, 3 and between the two support struts 5, 6 of the support frame 1. The tensioning bar 7 has a thread 8, in particular a so-called Dywidag thread. Its lower end is below the support frame 1, it is provided with a hook 9. For tensioning a vertebral nut 10 is on the tension rod 7 screwed on. Your contact surface engages over the two support struts 5, 6 of the support frame 1 and is supported against them.

Der Stützbock 1 ist in Stahl ausgeführt, die einzelnen Verbindungen sind geschweißt. Seine Länge in Richtung der beiden L-Profilstäbe 2, 3 ist 500 mm, seine Höhe in Richtung des U-Profilstabs 4 ist 430 mm. Der Stützbock 1 wiegt zusammen mit dem Spannstab 7 etwa 12,4 kg.The support frame 1 is made of steel, the individual connections are welded. Its length in the direction of the two L-profile bars 2, 3 is 500 mm, its height in the direction of the U-profile bar 4 is 430 mm. The support frame 1 weighs approximately 12.4 kg together with the tie rod 7.

Die in Fig. 2 gezeigte Spannschiene 11 besteht aus einem U-förmig gebogenen Blech. Als Aussparungen 12 zum Einhaken der Spannstäbe 7 sind ungefähr halbkreisförmige Löcher aus dem bogenförmigen Jochbereich des U-Profils ausgestanzt. An den beiden Rändern des U-Profils der Spannschiene 11 sind Befestigungslaschen 13 umgebogen oder angeschweißt. Diese Befestigungslaschen 13 sind zum Befestigen zweier herkömmlicher Holzträger beiderseits der Spannschiene 11 beispielsweise mittels Schrauben vorgesehen. Dadurch ergibt sich ein Doppelträger aus zwei voneinander beabstandeten Trägern, zwischen denen, an ihrer Unterseite, die Spannschiene 11 befestigt ist. Die beiden Träger können an weiteren Stellen mit Abstandshaltern aneinander befestigt sein. In den Zwischenraum zwischen den beiden Trägern können die Spannstäbe 7 hineingreifen und in die Aussparungen 12 in der Spannschiene 11 eingehakt werden. An beiden Enden der Spannschiene 11 sind Haken 14 zum Einhängen jeweils einer weiteren Spannschiene 11 angeordnet. Die Haken 14 sind einstückig mit der Spannschiene 11. Dadurch können beliebig viele Spannschienen 11 aneinander gehängt werden. Die beschriebene Spannschiene 11 ist ohne die Haken 14 800 mm lang, sie wiegt 7,6 kg. Zwischen den L-Profilstäben 2, 3 sind Stege 38 eingeschweißt, die das Befestigen der Spannstäbe 7 nicht behindern.The tensioning rail 11 shown in Fig. 2 consists of a U-shaped sheet. Approximately semicircular holes are punched out of the arcuate yoke area of the U-profile as recesses 12 for hooking in the tension rods 7. At the two edges of the U-profile of the tensioning rail 11, fastening tabs 13 are bent or welded. These fastening tabs 13 are provided for fastening two conventional wooden beams on both sides of the tensioning rail 11, for example by means of screws. This results in a double beam consisting of two spaced-apart beams, between which, on its underside, the tensioning rail 11 is fastened. The two supports can be fastened to one another at further points with spacers. The tension rods 7 can reach into the space between the two supports and can be hooked into the recesses 12 in the tension rail 11. At both ends of the tensioning rail 11, hooks 14 are arranged for hanging a further tensioning rail 11 each. The hooks 14 are in one piece with the tensioning rail 11. As a result, any number of tensioning rails 11 can be hung together. The tensioning rail 11 described is 800 mm long without the hooks 14, it weighs 7.6 kg. Between the L-profile bars 2, 3, webs 38 are welded in, which do not hinder the fastening of the tension bars 7.

Fig. 3 zeigt die Anwendung der erfindunggemäßen Schalungszwinge zur Schalung eines Unterzugs einer Betondecke. Auf ein Unterstellgerüst 15 sind vier Längsträger 16 aufgelegt. Auf diesen Längsträgern 16 stützt sich ein Querträger 17 ab. Der Querträger 17 ist als Doppelträger ausgebildet, er besteht aus zwei parallel mit Zwischenraum zueinander angeordneten herkömmlichen Holzträgern (Gitterträgern). Der besseren Darstellbarkeit wegen ist der vordere der beiden den Querträger 17 bildenden Holzträger nicht gezeichnet. Zwischen den beiden den Querträger 17 bildenden Holzträgern an deren Unterseite ist die Spannschiene 11 angebracht. Die Ebene ihrer Aussparungen 12 liegt im Bereich der unteren Gurte der Träger 17.Fig. 3 shows the application of the formwork clamp according to the invention for formwork of a beam of a concrete ceiling. Four side members 16 are placed on a support frame 15. A cross member 17 is supported on these longitudinal members 16. The cross member 17 is designed as a double girder, it consists of two conventional wooden girders (lattice girders) arranged parallel to one another with a space between them. For the sake of better representation, the front of the two wooden beams forming the cross beam 17 is not shown. The tensioning rail 11 is attached between the two wooden beams forming the cross beam 17 on the underside thereof. The level of their cutouts 12 lies in the region of the lower straps of the carrier 17th

Auf dem Querträger 17 befinden sich zwei Stützböcke 1. Die beiden senkrecht nach unten stehenden Schenkel der beiden L-Profilstäbe 2, 3 jedes Stützbocks 1 greifen in den Zwischenraum zwischen die beiden den Querträger 17 bildenden Holzträgern ein. Dadurch ist der Stützbock 1 auf dem Querträger 17 geführt.On the cross member 17 there are two support brackets 1. The two legs of the two L-shaped bars 2, 3 of each support bracket 1, which are positioned vertically downward, engage in the space between the two wooden beams forming the cross member 17. As a result, the support bracket 1 is guided on the cross member 17.

An dem senkrecht nach oben stehenden U-Profilstab 4 jedes Stützbocks 1 sind Schalelemente als Seitenschilde 18 befestigt. Ein Seitenschild 18 weist ein senkrecht stehendes stehendes Kantholz 19 auf, das vom U-Profilstab 4 aufgenommen und an diesem befestigt ist. An dem Kantholz 19 sind die zwei Längsträger 20, 21, und an diesen ist eine Schalhaut 22 befestigt.Formwork elements are attached as side shields 18 to the upright U-profile bar 4 of each support frame 1. A side plate 18 has a vertically standing squared timber 19 which is received by the U-shaped bar 4 and fastened to it. The two longitudinal beams 20, 21 are on the square timber 19, and a formwork skin 22 is fastened to these.

Zur Schalung der Unterseite des Unterzugs liegt eine Schalhaut 23 auf dem Querträger 17 auf. Jeder Stützbock 1 ist mit einem Spannstab 7 auf dem Querträger 17 festgespannt. Jeder Spannstab 7 ist in eine Aussparung 12 der Spannschiene 11 eingehakt; die auf den Spannstab 7 aufgeschraubte Wirbelmutter 10 stützt sich gegen die Stützstreben 5, 6 des Stützbocks 1 ab. Der Spannstab 7 verläuft in Bezug auf den zu schalenden Unterzug schräg nach unten innen. Gedachte Längsachsen der beiden Spannstäbe 7 einer Schalungszwinge schneiden sich unterhalb des Unterzugs.To formwork the underside of the beam, a formlining 23 lies on the cross member 17. Each support bracket 1 is clamped on the cross member 17 with a tie rod 7. Each tensioning rod 7 is hooked into a recess 12 in the tensioning rail 11; the vertebral nut 10 screwed onto the tie rod 7 is supported against the support struts 5, 6 of the support frame 1. The tie rod 7 runs obliquely downwards in relation to the beam to be shuttered. Imagined longitudinal axes of the two tie rods 7 of a formwork clamp intersect below the beam.

Die waagrechte Komponente der Spannkraft der beiden Stützböcke 1 einer Schalungszwinge wird über die Spannstäbe 7 in die Spannschiene 11 eingeleitet, wo sich diese Kraftkomponenten der beiden Spannkräfte gegeneinander aufheben. Der Querträger 17 braucht daher nur die senkrechte Komponente der Spannkräfte aufzunehmen.The horizontal component of the clamping force of the two support brackets 1 of a formwork clamp is introduced via the clamping rods 7 into the clamping rail 11, where these force components of the two clamping forces cancel each other out. The cross member 17 therefore only needs to absorb the vertical component of the clamping forces.

Am in Fig. 3 rechten Ende der Spannschiene 11 ist strichpunktiert eine weitere Spannschiene 11a angedeutet, die in die Spannschiene 11 eingehängt ist. Dadurch kann der Abstand der beiden Stützböcke 1 voneinander beliebig groß gewählt werden. Zum Befestigen der beiden Spannstäbe 7 an der Spannschiene 11 werden diese im Zwischenraum zwischen den beiden L-Profilstäben 2, 3 und den beiden Stützstreben 5, 6 des Stützbocks 1 schräg nach unten zwischen die beiden den Querträger 17 bildenden Holzträger geführt und in jeweils eine Aussparung 12 in der Spannschiene 11 eingehakt. Durch Festziehen der Wirbelmutter 10 auf dem Spannstab 7 wird der Stützbock 1 auf dem Querträger 17 festgespannt.At the right end of the tensioning rail 11 in FIG. 3, a further tensioning rail 11a is indicated by dash-dotted lines and is suspended in the tensioning rail 11. As a result, the distance between the two trestles 1 from one another can be chosen to be as large as desired. To attach the two tie rods 7 to the tensioning rail 11, these are guided in the space between the two L-shaped bars 2, 3 and the two support struts 5, 6 of the support bracket 1 obliquely downwards between the two wooden beams forming the cross member 17 and each in a recess 12 hooked into the tensioning rail 11. By tightening the vertebral nut 10 on the tie rod 7, the support bracket 1 is clamped on the cross member 17.

Die Spannstäbe 7 können so steil gestellt werden, daß die Stützböcke 1 auf dem Querträger 17 an ihrer jeweiligen Position auf dem Querträger 17 angepreßt werden. Die Spannstäbe 7 können jedoch auch so flach angeordnet werden, daß sie die beiden Stützböcke 1 auf dem Querträger 17 gegeneinander ziehen, bis die Seitenschilde 18 der Unterzugschalung gegen die Schalhaut 23 der Unterseite des Unterzugs stoßen und dadurch die Positionen der Stützböcke 1 in ihrer Stellung festlegen.The tie rods 7 can be set so steep that the support brackets 1 on the cross member 17 are pressed at their respective position on the cross member 17. The tie rods 7 can, however, also be arranged so flat that they pull the two support brackets 1 against one another on the cross member 17 until the side plates 18 of the girder formwork abut against the formlining 23 of the underside of the girder and thereby fix the positions of the support brackets 1 in their position .

Fig. 4 zeigt das Schalen eines freistehenden Randes einer Decke mit der erfindungsgemäßen Schalungszwinge. Die den Rand der Decke begrenzende Schalung 24 stützt sich gegen einen Stützbock 1 ab. Als Querträger 17 dienen wiederum zwei parallel zueinander verlaufende herkömmliche Holzträger, die einen Doppelträger bilden. Diese beiden Holzträger sind Teil der Deckenschalung. Ein separater Querträger 17 für die Schalungszwinge ist nicht notwendig. An der Unterseite der beiden den Querträger 17 bildenden Holzträger ist die Spannschiene 11 befestigt. Mittels der Wirbelmutter 10 wird der Stützbock 1 über den Spannstab 7 (in Fig. 4 als Strichpunktlinie angedeutet) auf dem Querträger 17 festgespannt. In Fig. 4 ist wie in Fig. 3 der besseren Darstellbarkeit wegen der vordere der beiden den Querträger 17 bildenden Holzträger nicht gezeichnet.Fig. 4 shows the formwork of a free-standing edge of a ceiling with the formwork clamp according to the invention. The formwork 24 delimiting the edge of the ceiling is supported against a support frame 1. In turn, two conventional wooden beams, which run parallel to one another and form a double beam, serve as cross beams 17. These two wooden beams are part of the slab formwork. A separate cross member 17 for the formwork clamp is not necessary. The tensioning rail 11 is fastened to the underside of the two wooden beams forming the cross beam 17. By means of the vertebral nut 10, the support bracket 1 is clamped on the cross member 17 via the tension rod 7 (indicated in FIG. 4 as a chain line). In FIG. 4, as in FIG. 3, for better illustration, the front of the two wooden beams forming the cross beam 17 is not shown.

Da bei dieser Anwendung in der Spannschiene 11 nur ein Stützbock 1 über den Spannstab 7 eingehakt ist, wird die Spannkraft des Stützbocks 1 vollständig in den Querträger 17 eingeleitet. Durch die Spannschiene 11 wird diese Krafteinleitung über deren Länge verteilt.Since in this application only one support bracket 1 is hooked in the tensioning rail 11 via the tension rod 7, the tensioning force of the support bracket 1 is completely introduced into the cross member 17. This introduction of force is distributed over its length by the tensioning rail 11.

Fig. 5 zeigt die Schalung eines Fundaments mit Hilfe der Erfindung. In eine bereits bestehende Bodenplatte 25 (Sauberkeitsschicht aus Magerbeton) aus Beton ist ein Anker 26 eingegossen. In ein aus der Bodenplatte 25 herausragendes Ende des Ankers 26 ist der Spannstab 7 eingehakt. Mittels der auf den Spannstab 7 aufgeschraubten Wirbelmutter 10 ist der Stützbock 1 auf der Bodenplatte 25 festgespannt. Der Stützbock 1 sitzt auf der Bodenplatte 25 auf.Fig. 5 shows the formwork of a foundation with the help of the invention. An anchor 26 is cast into an existing base plate 25 (clean layer made of lean concrete) made of concrete. The tie rod 7 is hooked into an end of the armature 26 protruding from the base plate 25. The support bracket 1 is clamped on the base plate 25 by means of the swivel nut 10 screwed onto the tension rod 7. The support frame 1 sits on the base plate 25.

Der U-Profilstab 4 des Stützbocks 1 nimmt ein senkrecht stehendes Kantholz 27 auf; an diesem ist eine aus zwei Dielen 28, 29 bestehende Schalhaut befestigt. Das Kantholz 27 und die beiden Dielen 28, 29 bilden den Seitenschild der Schalung eines aus Beton zu gießenden Fundaments 30.The U-section bar 4 of the support frame 1 receives a vertically standing square timber 27; a formwork skin consisting of two planks 28, 29 is fastened to this. The square timber 27 and the two planks 28, 29 form the side plate of the formwork of a foundation 30 to be cast from concrete.

Fig. 6 zeigt schematisch die Anwendung erfindungsgemäßen Schalungszwinge zur Schalung eines Kanals 31. Oberhalb des zu schalenden Kanals 31 ist quer zu diesem ein Doppelträger angeordnet, der aus zwei herkömmlichen Holzträgern besteht. Dieser Doppelträger bildet den Querträger 17 zweier Schalungszwingen zur Schalung der beiden Kanalwände 32, 33. Die Spannschiene 11 jeder Schalungszwinge befindet sich bei dieser Anwendung an der Oberseite des Querträgers 17. Die beiden Stützböcke 1 jeder Schalungszwinge sind über Spannstäbe 7 (in Fig. 6 durch Strichpunktlinien angedeutet) an der Unterseite des Querträgers 17 festgespannt. Die Stützböcke 1 ragen vom Querträger 17 nach unten. An ihnen sind die Seitenschilde 34 bis 37 zur Schalung der Außenseiten des Kanals 31 bzw. seiner Wände 32, 33 sowie zur Schalung der Innenseiten der Wände 32, 33 des Kanals 31 befestigt.Fig. 6 shows schematically the application of formwork clamp according to the invention for formwork of a channel 31. This double girder forms the crossbeam 17 of two formwork clamps for formworking the two channel walls 32, 33. In this application, the tensioning rail 11 of each formwork clamp is located on the top of the crossbeam 17. The two support brackets 1 of each formwork clamp are connected via tension rods 7 (in FIG. 6) Dashed lines indicated) clamped on the underside of the cross member 17. The support brackets 1 project downward from the cross member 17. The side shields 34 to 37 for formworking the outer sides of the channel 31 or its walls 32, 33 and for formworking the inner sides of the walls 32, 33 of the channel 31 are fastened to them.
