Abstract

The invention relates to a concrete shuttering, e.g. floor-border shuttering or joist shuttering, having a shuttering angle which exhibits a vertical profile (2) and a horizontal profile (1) which can be laid on the upper surface (5, 7) of a load-bearing member (6, 8), and having a fastening device (9) for fastening the shuttering angle on the load-bearing member. The invention consists in the fact that the fastening device (9, 26) exhibits a clamping connection with two legs (10, 11, 26) which can be pressed in a frictionally locking manner, by means of a bracing device (17, 34), onto the two side surfaces (19, 29) of the load-bearing member (6, 8). <IMAGE>

Description

Die Erfindung bezieht sich auf eine Betonschalung, z.B. eine Deckenrandabschalung oder Unterzugschalung, mit einem Abschalwinkel, der ein Vertikalprofil und ein auf eine obere Fläche eines Trägers auflegbares Horizontalprofil sowie eine Befestigungsvorrichtung für den Abschalwinkel auf dem Träger aufweist.The invention relates to concrete formwork, e.g. a ceiling edge formwork or joist formwork, with a formwork angle, which has a vertical profile and a horizontal profile that can be placed on an upper surface of a beam, and a fastening device for the formwork angle on the beam.

Bei einer durch die DE 40 13 093 A1 bekannten Schalung dieser Art besteht die Befestigungsvorrichtung aus einem um eine senkrechte Achse im Horizontalprofil schwenkbar gelagerten Doppelarm, der an seinen Enden abwärts gerichtete Klauen aufweist, deren Enden wiederum mit nach innen weisenden Laschen versehen sind, die beim Verschwenken des Doppelarms eine am Träger vorhandene Kante, beispielsweise einen Obergurt eines Holzgitterträgers, untergreifen können. Ein die Achse bildender drehbarer Bolzen weist an seinem oberen Ende ein Schraubengewinde auf, auf das eine sich auf die obere Fläche des Horizontalprofils abstützende Flügelmutter aufgeschraubt ist. Soll der Abschalwinkel auf dem Träger befestigt werden, so wird der Doppelarm zunächst so verschwenkt, daß die Laschen unter eine Kante des Trägers zu liegen kommen. Dann wird die Flügelmutter angespannt, die das Horizontalprofil des Abschalwinkels über geeignete Stützelement auf die obere Fläche aufpreßt und so den Abschalwinkel auf dem Träger befestigt. Die Höhe der Klauen an dem Doppelarm ist jedoch konstruktiv begrenzt, so daß der Abschalwinkel nur an Holzträgern mit I-Querschnitt befestigt werden kann, deren Obergurt eine bestimmt Höhe nicht überschreitet.In a formwork known from DE 40 13 093 A1 Art consists of the fastening device of a double arm pivotally mounted about a vertical axis in the horizontal profile, the ends of which have downward-pointing claws, the ends of which are in turn provided with tabs which, when the double arm is pivoted, have an edge on the support, for example an upper chord of a wooden lattice girder. A rotatable bolt forming the axis has at its upper end a screw thread onto which a wing nut is screwed, which is supported on the upper surface of the horizontal profile. If the shuttering angle is to be attached to the carrier, the double arm is first pivoted so that the tabs come to rest under one edge of the carrier. Then the wing nut is tightened, which presses the horizontal profile of the shuttering angle onto the upper surface via a suitable support element and thus fastens the shuttering angle to the support. However, the height of the claws on the double arm is structurally limited, so that the shuttering angle can only be attached to wooden beams with an I cross-section, the upper flange of which does not exceed a certain height.

Es ist jedoch erwünscht, daß derartige Abschalwinkel nicht nur an Holzträgern befestigt werden können, deren Obergurt unterschiedliche Höhen aufweist, vielmehr sollen bekannte Abschalwinkel auch an aus Kantholz oder dergleichen bestehenden Träger befestigt werden können, bei denen der Abstand einer Kante, die untergriffen werden kann, von der oberen Fläche des Trägers relativ groß ist. Auch ist bei dieser bekannten Befestigungsvorrichtung umständlich, daß der Drehbolzen zusammen mit dem Doppelarm und den Klauen stets soweit angehoben werden muß, daß die Laschen am unteren Ende der Klauen eine untere Fläche am Träger hintergreifen können. Bei unterschiedlichen Trägern muß diese Höhe jeweils wieder eingestellt werden.However, it is desirable that such shuttering angles can not only be fastened to wooden beams, the upper chord of which has different heights, but rather known shuttering angles can also be fastened to beams made of squared timber or the like, in which the distance of an edge which can be undercut, from the top surface of the beam is relatively large. It is also cumbersome in this known fastening device that the pivot pin together with the double arm and the claws must always be raised to such an extent that the tabs at the lower end of the claws can engage behind a lower surface on the carrier. With different beams, this height must in each case can be set again.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Betonschalung, z.B. einer Deckenrandabschalung oder Unterzugschalung eine Befestigung für einen Abschalwinkel zu entwicklen, der bei vielen Trägern unterschiedlicher Höhe eines Obergurtes oder eines Vierkantholzes ohne größere Verstellung angewandt werden kann.The invention has for its object, in a concrete formwork, e.g. to develop a fastening for a shuttering angle that can be used for many beams of different heights of an upper chord or a square timber without major adjustment.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die Befestigungsvorrichtung eine Klemmverbindung mit zwei Schenkeln aufweist, die durch eine Spannvorrichtung kraftschlüssig an die beiden Seitenflächen des Trägers anpreßbar sind.This object is achieved according to the invention in that the fastening device has a clamp connection with two legs, which can be positively pressed onto the two side surfaces of the carrier by a tensioning device.

Die erfindungsgemäße Befestigungsvorrichtung weist daher kein zur Funktion nötiges Teil auf, mit dem eine untere Fläche oder eine entsprechende Kante des Trägers untergriffen werden muß, sie ist daher weitgehend unabhängig von der Höhe des Trägers ohne Verstellen einsetzbar, da sie lediglich an den Seitenflächen, nicht aber an der Unterfläche eines Trägers angreift. Versuche haben ergeben, daß eine solche, im wesentlichen kraftschlüssige Verbindung zwischen Abschalwinkel und Träger für die Funktion eines Abschalwinkel völlig ausreichend ist.The fastening device according to the invention therefore has no part necessary for function with which a lower surface or a corresponding edge of the carrier has to be gripped, it can therefore be used largely independently of the height of the carrier without adjustment, since it is only on the side surfaces, but not attacks on the lower surface of a carrier. Tests have shown that such an essentially non-positive connection between the shuttering angle and the beam is completely sufficient for the function of a shuttering angle.

Bei Ausführungsformen der Erfindung weisen die Schenkelenden an den den Seitenflächen des Trägers zugewandten Flächen Vorsprünge auf, die sich beispielsweise bei Verwendung von Trägern aus Holz in die Holzoberfläche der Seitenflächen des Trägers etwas eindrücken und so diese Verbindung zwischen Träger und Befestigungsvorrichtung besonders stabil gestalten. Wo dies nicht erforderlich ist, können solche Vorsprünge auch fehlen.In embodiments of the invention, the leg ends on the surfaces facing the side surfaces of the carrier have projections which, for example when using wooden carriers, are somewhat pressed into the wooden surface of the side surfaces of the carrier and thus make this connection between carrier and fastening device particularly stable. Where this is not necessary, such protrusions can be used also missing.

Bei einer zweckmäßigen Ausführungsform der Erfindung weist die Befestigungsvorrichtung zwei Schenkel und ein diese Schenkel verbindendes Joch auf, ist also im Prinzip etwa U-förmig, wobei aber die Schwenkpunkte der Schenkel am Joch in einem Abstand voneinander angeordnet sind. Ist dieser Abstand so groß wie der Abstand der beiden Seitenflächen des Träger voneinander, so legen sich beim Spannen der Klemmverbindung die Enden der Schenkel, parallele Seitenflächen vorausgesetzt, mit ihrer ganzen Fläche an den Seitenflächen an. Weicht dieser Abstand der Schwenkpunkte von dem Abstand der Seitenflächen des Trägers ab, so kann es zweckmäßig sein, die an den Seitenflächen des Träger angreifenden Flächen der Schenkel mit einer leichten Rundung zu versehen, so daß der erfindungsgemäße Abschalwinkel auch in Verbindung mit Trägern verwendet werden kann, bei denen nicht nur ihre Höhe unterschiedlich ist, sondern auch ihre Breite.In an expedient embodiment of the invention, the fastening device has two legs and a yoke connecting these legs, so it is in principle approximately U-shaped, but the pivot points of the legs are arranged at a distance from one another on the yoke. If this distance is as large as the distance between the two side surfaces of the carrier from one another, the ends of the legs, provided parallel side surfaces are provided, rest with their entire surface on the side surfaces when the clamping connection is tensioned. If this distance between the pivot points deviates from the distance between the side surfaces of the carrier, it may be expedient to provide the surfaces of the legs which engage on the side surfaces of the carrier with a slight curve, so that the shuttering angle according to the invention can also be used in connection with carriers , where not only their height is different, but also their width.

Die Befestigungsvorrichtung kann bei Ausführungsformen der Erfindung durch eine separate Klammer gebildet sein. Dies hat den Vorteil, daß für verschiedene Anwendungsfälle optimal hierauf abgestimmte Klammern bereitgehalten werden können. Für die häufigen Holzbreiten 8-10 cm ist nur eine Klammer erforderlich. Dabei kann diese Klammer ebenfalls eine U-Form aufweisen und bei Ausführungsformen der Erfindung das die beiden Schenkel verbindende Joch federnd ausgebildet sein, so daß die Schenkel der durch die Spannvorrichtung auferlegten Schwenkbewegung ohne weiteres folgen können. Diese Ausführungsform der Erfindung kann dahingehend weiter ausgebildet sein, daß diese Feder eine S-Form aufweist, so daß sie bei großer Festigkeit einen verhältnismäßig großen Federweg aufweist und damit den Schenkeln auch einen verhältnismäßig großen Schwenkwinkel, gegebenenfalls gegen Federwirkung, erlaubt. Bei anderen Ausführungsformen der Erfindung sind die Schenkel der Klammer selbst federnd ausgebildet. In diesem Falle ist das die beiden Schenkel verbindende Joch steif, so daß ein Spannen der Spannvorrichtung, die gegebenenfalls auf halber Länge der Schenkel angreifen kann, keine Veränderung der Jochlänge hervorruft, sondern nur eine Bewegung der Schenkelenden gegeneinander.In embodiments of the invention, the fastening device can be formed by a separate clip. This has the advantage that brackets optimally matched to this can be kept ready for different applications. Only one bracket is required for the common wood widths of 8-10 cm. This bracket can also have a U-shape and, in embodiments of the invention, the yoke connecting the two legs can be resilient, so that the legs can easily follow the pivoting movement imposed by the tensioning device. This embodiment of the invention can be further developed in such a way that this spring has an S-shape, so that it has a relatively large spring travel with great strength and thus a relatively large leg large swivel angle, possibly against spring action, allowed. In other embodiments of the invention, the legs of the clip are themselves resilient. In this case, the yoke connecting the two legs is stiff, so that tensioning the tensioning device, which can possibly act on half the length of the legs, does not cause a change in the length of the yoke, but only a movement of the leg ends against one another.

Bei anderen Ausführungsformen der Erfindung ist die Befestigungsvorrichtung jedoch in den Abschalwinkel integriert, dessen Vertikalprofil einen U-förmigen Querschnitt aufweist. Dabei sind die Schenkel des U-förmigen Querschnitts über die Ansatzstelle des Horizontalprofils hinaus nach unten verlängert und diese Schenkel sind zumindest auf ihrem verlängerten Abschnitt gegeneinander beweglich. Eine Spannvorrichtung preßt diese Verlängerungen an die Seitenflächen des Trägers an. Dabei üben die über die Ansatzstelle des Horitonzalprofils hinaus nach oben ragenden Schenkelabschnitte die übliche Funktion des Abschalwinkels aus, sie dienen nämlich zur Anlage der Schalungsbretter der Betonschalung oder der Abstützung eines anderen Teiles der Schalung wie z.B. eines Geländerpfostens und zur Auflage der Deckenschalung.In other embodiments of the invention, however, the fastening device is integrated in the shuttering angle, the vertical profile of which has a U-shaped cross section. The legs of the U-shaped cross section are extended downward beyond the point of attachment of the horizontal profile and these legs are movable against one another at least on their extended section. A tensioning device presses these extensions onto the side surfaces of the carrier. The leg sections projecting upwards beyond the attachment point of the horizontal profile perform the usual function of the shuttering angle, namely they serve to support the shuttering boards of the concrete shuttering or to support another part of the shuttering, e.g. a railing post and to support the slab formwork.

Die Verlängerung der Schenkel des Horizontalprofils nach unten kann so gewählt sein, daß ihre Länge für die meisten Anwendungsfälle geeignet ist. Bei Ausführungsformen der Erfindung sind jedoch diese Schenkel des Vertikalprofils gegenüber dem Horizontalprofil längs verschiebbar geführt, so daß die Länge der über die Ansatzstelle des Horizontalprofils hinaus nach unten und nach oben ragenden Verlängerungen einstellbar ist.The extension of the legs of the horizontal profile downwards can be chosen so that its length is suitable for most applications. In embodiments of the invention, however, these legs of the vertical profile are guided so as to be longitudinally displaceable relative to the horizontal profile, so that the length of the extensions projecting downward and upward beyond the attachment point of the horizontal profile can be adjusted.

Diese Führung der Schenkel des Horizontalprofils des Abschalwinkels kann auch so ausgebildet sein, daß die Schenkel zumindest unterhalb der Ansatzstelle des Horizontalprofils federnd ausgebildet sind, so daß sie beim Anziehen der Spannvorrichtung mit einer bestimmten Federkraft an den Seitenflächen des Trägers anliegen, wenn das für eine Bewegung z.B. erforderliche Spiel der Schenkel in ihrem oberen Abschnitt bereits erschöpft ist und dort ein starrer, im Querschnitt U-förmiger Verband des Vertikalprofils besteht.This leadership of the legs of the horizontal profile of the shuttering angle can also be designed so that the legs are resilient at least below the attachment point of the horizontal profile, so that they rest on the side surfaces of the carrier when tightening the clamping device with a certain spring force, if that for movement e.g. required play of the legs is already exhausted in its upper section and there is a rigid, cross-sectionally U-shaped association of the vertical profile.

Bei Ausführungsformen der Erfindung kann die Spannvorrichtung aus einer Schraubverbindung bestehen, die in einem vom Jochteil des U-Querschnitts des Vertikalprofils nach innen in den Querschnitt ragenden Vorsprung geführt ist.In embodiments of the invention, the tensioning device can consist of a screw connection which is guided in a projection projecting inwards from the yoke part of the U-cross section of the vertical profile into the cross section.

Diese Ausführungsform kann dann, wenn die Schenkel des U-förmigen Querschitts des Vertikalprofils höhenverschiebbar geführt sind, dahingehend weiter ausgebildet sein, daß die Schenkel oder der Vorsprung ein Langloch aufweisen, das von der Spannvorrichtung durchsetzt ist.This embodiment can then, when the legs of the U-shaped cross section of the vertical profile are guided so as to be vertically displaceable, that the legs or the projection have an elongated hole which is penetrated by the tensioning device.

Bei Ausführungsformen der Erfindung kann die erfindungsgemäße Schalung auch so ausgebildet sein, daß das Horizontalprofil aus einer auf die Trägeroberfläche auflegbaren Grundplatte gebildet ist, die mehrere Durchbrüche zur Aufnahme von Befestigungsmitteln aufweist, die im eingeschalten Zustand des Abschalwinkels die Grundplatte durchdringen und in die Oberfläche der darunter angeordneten Ebene eindringen. Dadurch kann der Abschalwinkel, nachdem er durch die erfindungsgemäße Befestigungsvorrichtung an die beiden Seitenflächen des Trägers angepreßt ist, zusätzlich noch durch Nägel, Schrauben oder dergleichen befestigt werden, wenn der Abschalwinkel so stark belastet ist, daß eine solche Maßnahme zweckmäßig erscheint. Das Anwendungsgebiet des erfindungsgemäßen Abschalwinkels ist daher durch diese zusätzlich Befestigungsmöglichkeit noch größer als bei den im vorangehenden beschriebenen Ausführungsformen.In embodiments of the invention, the formwork according to the invention can also be designed such that the horizontal profile is formed from a base plate which can be placed on the support surface and which has a plurality of openings for receiving fasteners which penetrate the base plate when the switching-off angle is switched on and into the surface thereof arranged level penetrate. As a result, the stripping angle, after it has been pressed against the two side surfaces of the carrier by the fastening device according to the invention, can additionally be fastened by nails, screws or the like if the stripping angle is so heavily loaded that such a measure seems appropriate. The field of application of the shuttering angle according to the invention is therefore even greater than in the embodiments described above due to this additional fastening possibility.

Diese Ausführungsform der Erfindung kann dahingehend weiterausgebildet sein, daß das Horizontalprofil an seiner Unterseite profiliert ist. Dadurch ergibt sich eine gute Auflage auf der Trägeroberfläche.This embodiment of the invention can be developed in such a way that the horizontal profile is profiled on its underside. This results in a good support on the carrier surface.

Bei Ausführungsformen der Erfindung weisen die äußeren Schenkelenden rechtwinklig abgewinkelte Randstreifen auf, die eine gute Auflage des Abschalwinkels an einer ebenen Fläche der Schalung begünstigen.In embodiments of the invention, the outer leg ends have edge strips angled at right angles, which favor a good support of the shuttering angle on a flat surface of the formwork.

Auch kann bei einer Ausführungsform der Erfindung der der Schalung zugewandte Rand des im Querschnitt U-förmig ausgebildeten Vertikalprofils gegebenenfalls einschließlich der Randstreifen auf der Innenoberfläche abgeschrägt sein, so daß dieser Abschalwinkel nicht nur als Stütze für einzelne ebene Schalungselemente, sondern auch für zwei eine Ecke bildende Schalungselemente eingesetzt werden kann. Die Ecke der winkelig aneinanderanstoßenden Schalelemente greift dann in den Innenraum des im Querschnitt U-förmigen Vertikalprofils ein.Also, in one embodiment of the invention, the edge of the formwork facing the formwork, which is U-shaped in cross-section, may be chamfered, including the edge strips on the inner surface, so that this formwork angle is not only a support for individual flat formwork elements, but also for two forming a corner Formwork elements can be used. The corner of the angularly abutting formwork elements then engages in the interior of the vertical profile, which is U-shaped in cross section.

Der Abschalwinkel und auch die Befestigungsvorrichtung sind aus Stahl oder einem anderen geeigneten Metall hergestellt, beispielsweise aus einer geeigneten Aluminiumlegierung.The shuttering angle and also the fastening device are made from steel or another suitable metal, for example from a suitable aluminum alloy.

Bei der in den Figuren 1 und 2 dargestellten Ausführungsform der Erfindung weist ein Abschalwinkel ein Horizontalprofil 1 und ein an dessen Ende starr verbundenes, vorzugsweise verschweißtes Vertikalprofil 2 auf. Diese beiden Profile sind durch einen Druckstab 3 miteinander verbunden. Diese Teile bestehen vorzugsweise aus Metall, die einzelnen Teile können miteinander verschweißt oder als Gußteil, vorzugsweise als Aluminiumguß, hergestellt sein. Das Horizontalprofil weist an seiner Unterseite Rippen 4 auf, mit denen es auf der oberen Fläche 5 eines Obergurtes eines Holzgitterträgers 6 oder auf der oberen Fläche 7 eines Kantholzes 8 aufliegt.In the embodiment of the invention shown in FIGS. 1 and 2, a shuttering angle has a horizontal profile 1 and a vertical profile 2 which is rigidly connected, preferably welded, at the end thereof. These two profiles are connected by a pressure rod 3. These parts are preferably made of metal, the individual parts can be welded together or produced as a cast part, preferably as cast aluminum. The horizontal profile has ribs 4 on its underside, with which it rests on the upper surface 5 of an upper flange of a wooden lattice girder 6 or on the upper surface 7 of a square timber 8.

Die Befestigung des Abschalwinkels 1, 2 an dem Holzgitterträgers 6 erfolgt durch eine Klammer 9, die zwei Schenkel 10 und 11 aufweist, die an ihrem von der Schalung abgewandten Ende durch eine S-förmige Feder 12 zusammengehalten werden und an ihrem vorderen Ende Platten 13 und 14 tragen, die an ihrer einander zugekehrten Fläche kleine Vorsprünge 15 aufweisen. An der Innenseite der Feder 12 ist ein Bolzen 16 befestigt, mit dem die ganze Klammer 9 in einer entsprechenden Öffnung im Druckstab 3 in den Abschalwinkel eingehängt werden kann.The fastening of the shuttering angle 1, 2 to the wooden lattice girder 6 is carried out by a clip 9 which has two legs 10 and 11 which are held together at their end facing away from the formwork by an S-shaped spring 12 and plates 13 and 14 wear, which have small projections 15 on their facing surface. On the inside of the spring 12, a bolt 16 is fastened, with which the whole clamp 9 can be hung in the corresponding opening in the pressure rod 3 in the shuttering angle.

Die beiden Schenkel 10 und 11 sind etwa in der Mitte ihrer Länge durch eine Schraubverbindung 17 miteinander verbunden, von der lediglich ihr Außenmantel dargestellt ist. Am äußeren Ende der Schraubspindel befindet sich eine Flügelmutter 18, mit der die Maulweite zwischen den Platten 13 und 14 eingestellt werden kann.The two legs 10 and 11 are connected to one another approximately in the middle of their length by a screw connection 17, of which only their outer jacket is shown. At the outer end of the screw spindle there is a wing nut 18 with which the mouth width between the plates 13 and 14 can be adjusted.

Wird die Schraubspindel 17 angezogen, so werden die Platten 13 und 14 an die Seitenflächen 19 des Obergurtes des Holzgitterträgers 6 angepreßt. Über den die Klammer mit dem Abschalwinkel verbindenden Bolzen 16 und/oder über Schrägflächen 40, 41 an den Schenkeln 10, 11 wird hierdurch der Abschalwinkel fest in seiner Position gehalten.If the screw 17 is tightened, the plates 13 and 14 are pressed against the side faces 19 of the upper chord of the wooden lattice girder 6. Via the bolt 16 connecting the clamp with the shuttering angle and / or via inclined surfaces 40, 41 on the legs 10, 11, the shuttering angle is hereby held firmly in its position.

In dem Horizontalprofil 2 befinden sich noch Löcher 20, durch die Nägel, Schrauben oder dergleichen Befestigungsmittel eingeschlagen werden können, um das Horizontalprofil 2 in den Ausnahmefällen, in denen man befürchtet, daß die Befestigung des Abschalwinkels durch die Klammer 9 die von der Schalung auf das Vertikalprofil 2 ausgeübte Kraft nicht ganz aufnehmen kann, zusätzlich noch mit dem Holzgitterträger 6 zu verbinden.In the horizontal profile 2 there are still holes 20 through which nails, screws or similar fasteners can be hammered in to the horizontal profile 2 in exceptional cases in which it is feared that the fastening of the shuttering angle by the clamp 9 will result from the formwork on the Vertical profile 2 cannot fully absorb the force exerted, additionally with the wooden lattice girder 6 connect to.

Das Vertikalprofil hat bei dieser Ausführungsform der Erfindung einen U-förmigen Querschnitt, das Joch 21 des Querschnitts ist starr mit den Schenkeln 22 des Querschnitts verbunden. An ihren der Schalung zugewandten Rändern weisen die Schenkel 22 rechtwinklig abgewinkelte Randstreifen 23 und 24 auf, die zur Anlage an eine ebene Schalung dienen. An der Innenfläche der Schenkel 22 und anschließend an die Randstreifen 23 und 24 sind an diesen Rändern Schrägflächen 25 vorgesehen, die zur Anlage an einer Schalungsecke dienen. Der erfindungsgemäße Abschalwinkel kann daher sowohl zur Abstützung einer ebenen Schalung als auch zur Abstützung einer Schalungsecke dienen, so daß ein zweiter Abschalwinkel an der Schalungsecke eingespart wird.In this embodiment of the invention, the vertical profile has a U-shaped cross section, the yoke 21 of the cross section is rigidly connected to the legs 22 of the cross section. At their edges facing the formwork, the legs 22 have edge strips 23 and 24 which are angled at right angles and which are used for contacting a flat formwork. On the inner surface of the legs 22 and then on the edge strips 23 and 24, inclined surfaces 25 are provided on these edges, which serve to abut a formwork corner. The shuttering angle according to the invention can therefore serve both to support a flat formwork and to support a formwork corner, so that a second shuttering angle on the formwork corner is saved.

Bei der in den Figuren 3 bis 5 dargestellten Ausführungsform der Erfindung ist die Befestigungsvorrichtung, mit der der Abschalwinkel an einem Träger befestigt wird, in den Abschalwinkel selbst integriert. Hierzu sind die Schenkel 26 über die Stelle 27 hinaus nach unten verlängert, an der das Horizontalprofil 1 mit dem Joch 28 des U-förmigen Querschnitts des Vertikalprofils verbunden, beispielsweise verschweißt, ist. Die Schenkel 26 erstrecken sich daher parallel zu den Seitenflächen 29 des als Träger dienenden Kantholzes 8 nach unten.In the embodiment of the invention shown in FIGS. 3 to 5, the fastening device with which the shuttering angle is fastened to a carrier is integrated into the shuttering angle itself. For this purpose, the legs 26 are extended downward beyond the point 27 at which the horizontal profile 1 is connected, for example welded, to the yoke 28 of the U-shaped cross section of the vertical profile. The legs 26 therefore extend parallel to the side surfaces 29 of the square timber 8 serving as a carrier downward.

Die Schenkel 26 sind an ihrem oberen Ende durch eine U-förmige Feder 30 miteinander verbunden und an dem Joch 28 mit etwas Spiel geführt. Vom Joch 28 erstreckt sich ein bei dieser Ausführungsform kastenförmiger Vorsprung 31 in den von dem U-förmigen Horizontalprofil umschlossenen Raum. Die Schenkel 26 sind mit Spiel an den Rändern des Jochs 28 so geführt, daß sie beim Anpressen an die Seitenflächen 29 eine gegeneinander gerichtete Bewegung ausführen können. In dem Vorsprung 31 ist eine Schraubspindel 34 gelagert, die an ihrem äußeren Ende eine Flügelmutter 32 trägt, mit der die Schenkel 26 gegen die Seitenflächen 29 des Trägers 8 angepreßt werden können, so daß hierdurch der Abschalwinkel fest mit dem Träger 8 verbunden ist. Auch in diesem Falle kann das Horizontalprofil noch Löcher aufweisen, durch die dieses Profil noch zusätzlich mit Hilfe von Nägeln oder dergleichen am Träger 8 befestigbar ist. Im Normalfall reicht jedoch die Kraft, mit der die Schenkel 26 an den Träger 8 angepreßt werden, vollständig aus, um eine übliche Schalung gegen den beim Einfüllen des Betons entstehenden Druck festzuhalten.The legs 26 are connected to one another at their upper end by a U-shaped spring 30 and are guided on the yoke 28 with some play. In this embodiment, a box-shaped projection 31 extends from the yoke 28 into the space enclosed by the U-shaped horizontal profile. The legs 26 are so with play on the edges of the yoke 28 performed that they can perform a counter-movement when pressed against the side surfaces 29. In the projection 31, a screw spindle 34 is mounted, which carries at its outer end a wing nut 32 with which the legs 26 can be pressed against the side surfaces 29 of the carrier 8, so that the shuttering angle is thereby firmly connected to the carrier 8. In this case too, the horizontal profile can still have holes through which this profile can additionally be fastened to the carrier 8 with the aid of nails or the like. In the normal case, however, the force with which the legs 26 are pressed against the support 8 is completely sufficient to hold a conventional formwork against the pressure which arises when the concrete is poured in.

Bei der in den Figuren 3 bis 5 dargestellten Ausführungsform der Erfindung sind die Schenkel 26 an dem Joch 28 höhenverschiebbar geführt, so daß die Länge des unter oder über die Anlagestelle 27 reichenden Abschnittes des Vertikalprofils eingestellt werden kann. Hierzu weisen die Schenkel 26 ein Langloch 33 auf, durch das die Enden der Schraubspindel 34 hindurchtreten.In the embodiment of the invention shown in FIGS. 3 to 5, the legs 26 are guided so as to be vertically displaceable on the yoke 28, so that the length of the section of the vertical profile reaching below or above the contact point 27 can be adjusted. For this purpose, the legs 26 have an elongated hole 33 through which the ends of the screw spindle 34 pass.

Die Feder 30 ist so steif, daß sie eine beim Anziehen der Schraubspindel auftretende Knicklast aufnehmen kann und daher der unter die Ansatzstelle 27 herunterreichende Abschnitt des Vertikalprofils bzw. der Schenkel 26 stets parallel und großflächig an der Fläche 29 angepreßt wird.The spring 30 is so stiff that it can absorb a buckling load occurring when the screw spindle is tightened, and therefore the section of the vertical profile or the leg 26 that extends below the attachment point 27 is always pressed parallel and over a large area on the surface 29.

In Fig. 4 ist dargestellt, wie eine durch Schalelemente 35 und 36 gebildete Schalungsecke durch den Abschalwinkel 1, 2, 3 mit Hilfe der Schrägflächen 25 abgestützt wird.4 shows how a formwork corner formed by formwork elements 35 and 36 is supported by the formwork angle 1, 2, 3 with the help of the inclined surfaces 25.

In Fig. 5 ist die in den Figuren 3 und 4 dargestellte Ausführungsform in ihrer Anwendung an einem Holzträger dargestellt, der einen Obergurt 37 und einen Untergurt 38 aufweist, die durch einen Steg 39 miteinander verbunden sind.5 is the embodiment shown in Figures 3 and 4 shown in their application on a wooden support which has an upper flange 37 and a lower flange 38, which are connected to one another by a web 39.

Bei der Ausführungsform nach Figuren 1 und 2 sind die Schenkel 10 und 11 über die S-förmige Feder 12 miteinander verbunden. Bei der Betätigung der Spannvorrichtung 17 liegen die Schwenkpunkte der Schenkel 10 und 11 in einem Abstand voneinander, nämlich an den Stellen, an denen die Feder 12 mit den Schenkeln 10 und 11 verbunden ist. Bei der Ausführungsform nach Figuren 3 bis 5 liegen die Schwenkachsen der Schenkel 26 ebenfalls an den Stellen, an denen die oberen Enden dieser Schenkel 26 mit der Feder 30 bzw. dem Joch der U-förmigen Feder 30 verbunden sind.In the embodiment according to FIGS. 1 and 2, the legs 10 and 11 are connected to one another via the S-shaped spring 12. When the tensioning device 17 is actuated, the pivot points of the legs 10 and 11 lie at a distance from one another, namely at the points at which the spring 12 is connected to the legs 10 and 11. In the embodiment according to FIGS. 3 to 5, the pivot axes of the legs 26 also lie at the points at which the upper ends of these legs 26 are connected to the spring 30 or the yoke of the U-shaped spring 30.

Die Schrägflächen 25 und die Befestigungslöcher 20 können auch bei Schalungen vorgesehen sein, bei denen die Abschalwinkel mit anderen Klammern oder anderen Befestigungsvorrichtungen an den Trägern aus Holz oder Metall oder auf anderen Unterlagen befestigt sind.The inclined surfaces 25 and the fastening holes 20 can also be provided in formwork in which the shuttering angles are fastened to the beams made of wood or metal or on other supports using other brackets or other fastening devices.

Die Schenkel 10, 11 in Fig. 2 können auch als Torsionsfedern ausgebildet sein und so eine möglichst ebene Anlage der Platten 13, 14 gewährleisten.The legs 10, 11 in FIG. 2 can also be designed as torsion springs and thus ensure that the plates 13, 14 are as level as possible.
