Definitions

  • the invention relates to a concrete formwork panel.
  • frame formwork panels used today are designed as frame formwork panels. They consist essentially of a plate-like formlining, which is often designed as a chipboard with a smooth surface, and a stiffening frame made of metal profiles on the back.
  • the manufacture of the profile frame in particular is complex because the metal profiles have to be cut to length, welded together and color-coated.
  • frame formwork panels have a relatively high weight per unit area of formwork skin, so that the formwork panels, apart from very small formwork panel sizes, have to be moved by crane.
  • the invention has for its object to provide a concreting formwork panel that weighs less formwork per unit area than conventional formwork panels. As a result, larger formwork panels can be moved and set up by hand than before. Transport to the construction site is made easier. There are also opportunities for significantly more rational and cost-effective production.
  • the formwork panel preferably has edge components that are connected to the support structure at least along two opposite edges.
  • the components mentioned including the conventionally non-existent, plate-like back component or back area, are included in the static load-bearing function of the entire panel structure, so that optimized static conditions and material utilization result. This results in weight savings.
  • the struts formed by the intermediate area or spacing component are preferably diagonal struts of alternating direction of inclination.
  • the control panel like conventional control panels, is preferably rectangular or square in plan view. The components mentioned need not necessarily be in one piece, although this is preferred for each of the components.
  • Edge components and / or rear grooves are preferably provided for attaching connecting locks along four edges of the formwork panel.
  • the formwork panel consists predominantly or entirely of plastic.
  • other materials are also possible, in particular wood, metal, etc.
  • a construction is very particularly preferred in which the formwork panel - having no pronounced edge components or without the edge components or including the edge components on two opposite edges - is integrally made of extruded plastic. It is possible to attach two or four edge components, in particular made of metal, to this integral, extruded plastic part, for example by gluing, riveting or the like. Alternatively, it is possible to manufacture the components mentioned at the beginning and then to connect them to one another by gluing, riveting, plastic welding or the like. Another preferred alternative is to manufacture the front component and the rear component from a sheet metal plate and to produce the spacer component from a zigzag-shaped sheet metal plate; these components are then firmly connected to one another, in particular by spot welding or riveting.
  • edge regions of the formwork panel can be formed by parts of the front component, the rear component and / or the spacer component.
  • edge components in particular from thicker sheet metal, and to connect them to the other components.
  • the formwork can be produced by extrusion in spite of the cross section in the manner of a lattice girder, since the cross section does not change along the formwork panel. This also simplifies production in the metal construction of the formwork panel.
  • the static structure of a box girder is obtained in a second section at right angles to the cross section mentioned.
  • the front component, the rear component and the spacer component are formed by a, preferably integral, composite plate. Suitable composite panels can be produced very efficiently.
  • the described edge components can preferably be attached to the composite panel.
  • the rear channels mentioned above are designed in such a way that connecting locks for aligned, aligned clamping of adjacent formwork panels can be attached.
  • the channels have undercuts, the channels are preferably undercut on their sides facing the edge.
  • the undercuts are preferably V-shaped.
  • the channels can also be used to manually grip the formwork panel.
  • Outer, longitudinal grooves are preferably provided on at least two opposite side surfaces. In this way, defined, mutual contact areas are created between two neighboring formwork panels, namely an investment area in the area of the front and another investment area in the area of the back.
  • the support structure has cavities
  • the cavities can preferably be foamed, at least in the area adjacent to the formwork panel front.
  • the material walls of the spacing component can be provided closer together there.
  • the formwork panel has half holes in its edge area, which are open to its rear and to its front side, so that when formwork panels are placed next to one another, complete holes result through the mutual addition of half holes, through which rods can be inserted.
  • These are primarily fixing bars for fixing the spatial position of the formwork panels for concreting and spacer bars for fixing the mutual spacing of opposing formwork panels when concreting walls or the like.
  • the formwork panels can have an overall angular shape, in particular for concreting square columns or concreting walls that converge at an angle or at right angles.
  • Suitable plastics for producing the formwork panel are familiar to the person skilled in the art.
  • PVC and fiber-reinforced plastics are just a few examples among many possible ones. If the material aluminum has been mentioned above, this obviously does not only mean pure aluminum, but also includes suitable aluminum alloys.
  • the invention also relates to a concrete formwork which has a plurality of formwork panels according to the invention which are clamped together by means of connecting locks attached on the rear.
  • the shuttering panel 2 shown in FIG. 1 is made of extruded plastic, the direction of extrusion being perpendicular to the plane of the drawing.
  • the formwork panel 2 consists essentially of a front component 4 in the form of a plane-parallel plate, a back component 6 in the form of a plane-parallel plate, a spacer component 8 in the form of walls placed in a zigzag shape, and two edge components 10 on two opposite formwork panel edges. Because of the shape of the edge components 10, reference is expressly made to FIG. 1 and also to the remaining figures.
  • the back component 6 is less wide than the front component 4, so that a groove 12 is formed on the back of the formwork panel 2 between an edge component 10 and the back component 6, which extends in the longitudinal direction of the formwork panel 2.
  • Each of the two channels 12 is undercut V-shaped on its side facing the edge, because the rear, widened foot of the edge component 10 merges into a narrower cross section there.
  • each of the two edge components 10 has a longitudinal groove 14 on its outside.
  • FIG. 2 the details described can be seen even more clearly because of the enlarged scale.
  • An inclined wall 18 (which can be attributed to the edge component 10 or the spacing component 8) leads obliquely from the V-shaped, bead-like undercut 16 to the next wall of the spacing component 8.
  • the formwork panel 2 can also be formed without a pronounced edge component 10.

Description

Die Erfindung bezieht sich auf eine Betonierungs-Schaltafel.The invention relates to a concrete formwork panel.

Die meisten heute eingesetzten Betonierungs-Schaltafeln sind als Rahmenschalungstafeln ausgebildet. Sie bestehen im wesentlichen aus einer plattenartigen Schalhaut, die häufig als Preßspanplatte mit glatter Oberfläche ausgebildet ist, und einem rückseitigen, versteifenden Gerippe aus Metallprofilen. Die Fertigung insbesondere des Profilgerippes ist aufwendig, weil die Metallprofile auf Länge geschnitten, miteinander verschweißt und farbbeschichtet werden müssen. Außerdem haben derartige Rahmenschalungstafeln ein relativ hohes Gewicht pro Flächeneinheit Schalhaut, so daß die Schalungstafeln, abgesehen von sehr kleinen Schalungstafelgrößen, mit dem Kran bewegt werden müssen.Most concrete formwork panels used today are designed as frame formwork panels. They consist essentially of a plate-like formlining, which is often designed as a chipboard with a smooth surface, and a stiffening frame made of metal profiles on the back. The manufacture of the profile frame in particular is complex because the metal profiles have to be cut to length, welded together and color-coated. In addition, such frame formwork panels have a relatively high weight per unit area of formwork skin, so that the formwork panels, apart from very small formwork panel sizes, have to be moved by crane.

Der Erfindung liegt die Aufgabe zugrunde, eine Betonierungs-Schaltafel zu schaffen, die pro Flächeneinheit Schalhaut weniger wiegt als herkömmliche Schaltafeln. Infolgedessen können größere Schaltafeln als bisher von Hand bewegt und aufgestellt werden. Der Transport zur Baustelle erleichtert sich. Außerdem ergeben sich Möglichkeiten für eine deutlich rationellere und kostengünstigere Herstellung.The invention has for its object to provide a concreting formwork panel that weighs less formwork per unit area than conventional formwork panels. As a result, larger formwork panels can be moved and set up by hand than before. Transport to the construction site is made easier. There are also opportunities for significantly more rational and cost-effective production.

Zur Lösung dieser Aufgabe weist die Betonierungs-Schaltafel erfindungsgemäß auf:

  • a) eine Schaltafel-Tragstruktur mit einem plattenartigen Vorderbereich bzw. Vorderbestandteil als Schalhaut, einem plattenartigen Rückbereich bzw. Rückbestandteil und einem den Abstand zwischen dem Vorderbereich und dem Rückbereich überbrückenden Zwischenbereich bzw. Abstandsbestandteil, wobei die Tragstruktur einen Querschnitt nach Art eines Gitterträgers mit schräg verlaufenden, durch den Zwischenbereich gebildeten Streben hat; und
  • b) für das Ansetzen von benachbarte Schaltafeln verklammernden Verbindungsschlössern ausgebildete, rückseitige Rinnen, die in der Nähe von mindestens zwei gegenüberliegenden Rändern der Schaltafel vorgesehen sind.
To solve this task, the concrete formwork panel according to the invention has:
  • a) a formwork support structure with a plate-like front area or front component as formwork skin, a plate-like back area or rear component and an intermediate area or spacing element bridging the distance between the front area and the rear area, the support structure having a cross section in the manner of a lattice girder with an inclined profile , struts formed by the intermediate area; and
  • b) rear gutters designed for the attachment of connecting locks which clamp adjacent formwork panels and which are in the vicinity of at least two opposite edges of the formwork panel are provided.

Vorzugsweise weist die Schaltafel mindestens entlang von zwei gegenüberliegenden Rändern Randbestandteile auf, die mit der Tragstruktur verbunden sind.The formwork panel preferably has edge components that are connected to the support structure at least along two opposite edges.

Bei der erfindungsgemäßen Schaltafel sind die genannten Bestandteile, darunter auch der herkömmlicherweise nicht vorhandene, plattenartige Rückbestandteil bzw. Rückbereich, in die statische Tragfunktion des gesamten Schaltafelgebildes einbezogen, so daß sich optimierte statische Verhältnisse und Materialausnutzung ergeben. Hieraus resultiert Gewichtsersparnis. Die durch den Zwischenbereich bzw. Abstandsbestandteil gebildeten Streben sind vorzugsweise diagonale Streben wechselnder Schrägungsrichtung. Die Schalttafel ist, wie herkömmliche Schaltafeln, in Draufsicht vorzugsweise rechteckig oder quadratisch. Die genannten Bestandteile müssen jeweils für sich nicht unbedingt einstückig sein, wiewohl dies für jeden der Bestandteile bevorzugt ist.In the formwork panel according to the invention, the components mentioned, including the conventionally non-existent, plate-like back component or back area, are included in the static load-bearing function of the entire panel structure, so that optimized static conditions and material utilization result. This results in weight savings. The struts formed by the intermediate area or spacing component are preferably diagonal struts of alternating direction of inclination. The control panel, like conventional control panels, is preferably rectangular or square in plan view. The components mentioned need not necessarily be in one piece, although this is preferred for each of the components.

Vorzugsweise sind Randbestandteile und/oder rückseitige Rinnen für das Ansetzen von Verbindungsschlössern entlang von vier Rändern der Schaltafel vorgesehen.Edge components and / or rear grooves are preferably provided for attaching connecting locks along four edges of the formwork panel.

Nach einer ganz besonders bevorzugten Ausgestaltung der Erfindung besteht die Schaltafel überwiegend oder vollständig aus Kunststoff. Es sind aber auch andere Materialien möglich, insbesondere Holz, Metall etc. Insbesondere bei größeren Schaltafeln oder hohen Anforderungen an die Kraftübertragungsfähigkeit von Verklammerungen zwischen benachbarten Schaltafeln ist es bevorzugt, insbesondere die Randbestandteile aus Metall, vorzugsweise aus stranggepreßten Aluminiumprofilen oder aus Stahlblechprofilen, zu machen.According to a very particularly preferred embodiment of the invention, the formwork panel consists predominantly or entirely of plastic. However, other materials are also possible, in particular wood, metal, etc. In particular in the case of larger formwork panels or high demands on the force transmission capability of brackets between adjacent formwork panels, it is preferred in particular to make the edge components from metal, preferably from extruded aluminum profiles or from sheet steel profiles.

Ganz besonders bevorzugt ist eine Bauweise, bei der die Schaltafel - keine ausgeprägten Randbestandteile aufweisend oder ohne die Randbestandteile oder einschließlich der Randbestandteile an zwei gegenüberliegenden Rändern - integral aus extrudiertem Kunststoff besteht. Es ist möglich, an diesem integralen, extrudierten Kunststoffteil zwei oder vier Randbestandteile, insbesondere aus Metall, zu befestigen, beispielsweise durch Kleben, Nieten oder dergleichen. Alternativ ist es möglich, die eingangs genannten Bestandteile jeweils für sich herzustellen und anschließend durch Kleben, Nieten, Kunststoffschweißen oder dergleichen miteinander zu verbinden. Eine ebenfalls bevorzugte Alternative besteht darin, den Vorderbestandteil und den Rückbestandteil jeweils aus einer Blechplatte zu fertigen und den Abstandsbestandteil aus einer zick-zack-förmig gebogenen Blechplatte zu fertigen; diese Bestandteile werden dann fest miteinander verbunden, insbesondere durch Punktschweißungen oder Nieten. Diese Variante kann ohne ausgeprägte Randbestandteile ausgebildet sein, wobei Randbereiche der Schaltafel von Teilen des Vorderbestandteils, des Rückbestandteils und/oder des Abstandsbestandteils gebildet sein können. Es ist aber auch möglich, gesonderte Randbestandteile, insbesondere aus dickerem Blech, zu fertigen und mit den anderen Bestandteilen zu verbinden.A construction is very particularly preferred in which the formwork panel - having no pronounced edge components or without the edge components or including the edge components on two opposite edges - is integrally made of extruded plastic. It is possible to attach two or four edge components, in particular made of metal, to this integral, extruded plastic part, for example by gluing, riveting or the like. Alternatively, it is possible to manufacture the components mentioned at the beginning and then to connect them to one another by gluing, riveting, plastic welding or the like. Another preferred alternative is to manufacture the front component and the rear component from a sheet metal plate and to produce the spacer component from a zigzag-shaped sheet metal plate; these components are then firmly connected to one another, in particular by spot welding or riveting. This variant can be designed without pronounced edge components, wherein edge regions of the formwork panel can be formed by parts of the front component, the rear component and / or the spacer component. However, it is also possible to manufacture separate edge components, in particular from thicker sheet metal, and to connect them to the other components.

Wenn wie bevorzugt, die im Querschnitt als Streben erscheinenden Komponenten in Längsrichtung der Schaltafel durchgehende Wände sind, läßt sich die Schaltafel trotz des Querschnitts nach Art eines Gitterträgers durch Extrudieren herstellen, da sich der Querschnitt längs der Schaltafel nicht ändert. Auch bei der Metallbauweise der Schaltafel ergibt sich hiermit eine Herstellungsvereinfachung. In einem zweiten Schnitt rechtwinklig zu dem genannten Querschnitt ergibt sich der statische Aufbau eines Kastenträgers.If, as is preferred, the components which appear as struts in the cross section in the longitudinal direction of the formwork are continuous walls, the formwork can be produced by extrusion in spite of the cross section in the manner of a lattice girder, since the cross section does not change along the formwork panel. This also simplifies production in the metal construction of the formwork panel. The static structure of a box girder is obtained in a second section at right angles to the cross section mentioned.

Es ist ferner eine bevorzugte Möglichkeit, daß der Vorderbestandteil, der Rückbestandteil und der Abstandsbestandteil durch eine, vorzugsweise integrale, Verbundplatte gebildet sind. Geeignete Verbundplatten sind sehr rationell herstellbar. Vorzugsweise können an der Verbundplatte die geschilderten Randbestandteile befestigt werden.It is also a preferred possibility that the front component, the rear component and the spacer component are formed by a, preferably integral, composite plate. Suitable composite panels can be produced very efficiently. The described edge components can preferably be attached to the composite panel.

Die weiter vorn angesprochenen, rückseitigen Rinnen sind so ausgebildet, daß dort Verbindungsschlösser zum ausgerichteten, fluchtenden Verklammern benachbarter Schaltafeln angesetzt werden können. Sofern die Rinnen Hinterschneidungen aufweisen, sind die Rinnen vorzugsweise an ihren randzugewandten Seiten hinterschnitten. Die Hinterschneidungen haben vorzugsweise V-Form. Außerdem können die Rinnen zum manuellen Greifen der Schaltafel benutzt werden.The rear channels mentioned above are designed in such a way that connecting locks for aligned, aligned clamping of adjacent formwork panels can be attached. If the channels have undercuts, the channels are preferably undercut on their sides facing the edge. The undercuts are preferably V-shaped. The channels can also be used to manually grip the formwork panel.

Vorzugsweise sind an mindestens zwei gegenüberliegenden Seitenflächen äußere, längsverlaufende Rinnen vorgesehen. Auf diese Weise entstehen definierte, gegenseitige Anlagebereiche zwischen zwei benachbarten Schaltafeln, und zwar ein Anlagebereich im Bereich der Vorderseite und ein weiterer Anlagebereich im Bereich der Rückseite.Outer, longitudinal grooves are preferably provided on at least two opposite side surfaces. In this way, defined, mutual contact areas are created between two neighboring formwork panels, namely an investment area in the area of the front and another investment area in the area of the back.

Wenn, wie bevorzugt, die Tragstruktur Hohlräume aufweist, können - mindestens in dem der Schaltafel-Vorderseite benachbarten Bereich - die Hohlräume vorzugsweise ausgeschäumt sein. Alternativ können die Materialwände des Abstandsbestandteils dort dichter beeinander vorgesehen sein. Diese Weiterbildungen erbringen den Vorteil, daß die Schaltafel insbesondere von der Vorderseite her durch die Schalhaut hindurch nagelbar ist. Außerdem läßt sich mit diesem Aufbau verhindern, daß flüssiger Beton in die Hohlräume der Schaltafel hineinläuft.If, as preferred, the support structure has cavities, the cavities can preferably be foamed, at least in the area adjacent to the formwork panel front. Alternatively, the material walls of the spacing component can be provided closer together there. These developments have the advantage that the formwork panel can be nailed through the formlining, in particular from the front. This structure also prevents liquid concrete from running into the cavities in the formwork panel.

Vorzugsweise weist die Schaltafel in ihrem Randbereich Halblöcher auf, die zu ihrer Rückseite und zu ihrer Vorderseite offen sind, so daß sich bei nebeneinander gesetzten Schaltafeln durch gegenseitige Ergänzung von Halblöchern vollständige Löcher ergeben, durch die Stäbe gesteckt werden können. Dabei handelt es sich in erster Linie um Fixierungsstäbe zum Fixieren der räumlichen Lage der Schaltafeln für das Betonieren und um Abstandsstäbe zum Fixieren des gegenseitigen Abstands von gegenüberliegenden Schaltafeln beim Betonieren von Wänden oder dergleichen.Preferably, the formwork panel has half holes in its edge area, which are open to its rear and to its front side, so that when formwork panels are placed next to one another, complete holes result through the mutual addition of half holes, through which rods can be inserted. These are primarily fixing bars for fixing the spatial position of the formwork panels for concreting and spacer bars for fixing the mutual spacing of opposing formwork panels when concreting walls or the like.

Die Schaltafeln können insgesamt eine Winkelgestalt haben, insbesondere für das Betonieren von eckigen Säulen oder das Betonieren von winklig bzw. rechtwinklig zusammenlaufenden Wänden.The formwork panels can have an overall angular shape, in particular for concreting square columns or concreting walls that converge at an angle or at right angles.

Geeignete Kunststoffe zum Herstellen der Schaltafel sind dem Fachmann geläufig. Als wenige Beispiele unter vielen möglichen seien PVC und faserverstärkte Kunststoffe genannt. Wenn vorstehend von dem Material Aluminium gesprochen worden ist, bedeutet dies selbstverständlich nicht nur Reinaluminium, sondern schließt auch geeignete Aluminiumlegierungen ein.Suitable plastics for producing the formwork panel are familiar to the person skilled in the art. PVC and fiber-reinforced plastics are just a few examples among many possible ones. If the material aluminum has been mentioned above, this obviously does not only mean pure aluminum, but also includes suitable aluminum alloys.

Gegenstand der Erfindung ist ferner eine Betonierungs-Schalung, die mehrere erfindungsgemäße Schaltafeln aufweist, die mittels rückseitig angesetzter Verbindungsschlösser miteinander verklammert sind.The invention also relates to a concrete formwork which has a plurality of formwork panels according to the invention which are clamped together by means of connecting locks attached on the rear.

Die in Fig. 1 gezeichnete Schaltafel 2 besteht integral aus extrudiertem Kunststoff, wobei die Extrusionsrichtung senkrecht zur Zeichnungsebene liegt. Die Schaltafel 2 besteht im wesentlichen aus einem Vorderbestandteil 4 in Form einer planparallelen Platte, einem Rückbestandteil 6 in Form einer planparallelen Platte, einem Abstandsbestandteil 8 in Form von zick-zack-förmig gestellten Wänden, und zwei Randbestandteilen 10 an zwei gegenüberliegenden Schaltafelrändern. Wegen der Gestalt der Randbestandteile 10 wird ausdrücklich auf Fig. 1 sowie auch die restlichen Figuren hingewiesen.The shuttering panel 2 shown in FIG. 1 is made of extruded plastic, the direction of extrusion being perpendicular to the plane of the drawing. The formwork panel 2 consists essentially of a front component 4 in the form of a plane-parallel plate, a back component 6 in the form of a plane-parallel plate, a spacer component 8 in the form of walls placed in a zigzag shape, and two edge components 10 on two opposite formwork panel edges. Because of the shape of the edge components 10, reference is expressly made to FIG. 1 and also to the remaining figures.

Der Rückbestandteil 6 ist weniger breit als der Vorderbestandteil 4, so daß an der Rückseite der Schaltafel 2 jeweils zwischen einem Randbestandteil 10 und dem Rückbestandteil 6 eine Rinne 12 gebildet ist, die sich in Längsrichtung der Schaltafel 2 erstreckt. Jede der beiden Rinnen 12 ist an ihrer randzugewandten Seite V-förmig hinterschnitten, weil der rückwärtige, verbreiterte Fuß des Randbestandteils 10 dort in einen schmaleren Querschnitt übergeht.The back component 6 is less wide than the front component 4, so that a groove 12 is formed on the back of the formwork panel 2 between an edge component 10 and the back component 6, which extends in the longitudinal direction of the formwork panel 2. Each of the two channels 12 is undercut V-shaped on its side facing the edge, because the rear, widened foot of the edge component 10 merges into a narrower cross section there.

Ferner erkennt man, daß jeder der beiden Randbestandteile 10 an seiner Außenseite eine längsverlaufende Rinne 14 aufweist.It can also be seen that each of the two edge components 10 has a longitudinal groove 14 on its outside.

In Fig. 2 erkennt man die beschriebenen Details wegen des vergrößerten Maßstabs noch deutlicher. Von der V-förmigen, sickenartigen Hinterschneidung 16 führt eine Schrägwand 18 (die man dem Randbestandteil 10 oder dem Abstandsbestandteil 8 zurechnen kann) schräg zu der nächsten Wand des Abstandsbestandteils 8.In Fig. 2 the details described can be seen even more clearly because of the enlarged scale. An inclined wall 18 (which can be attributed to the edge component 10 or the spacing component 8) leads obliquely from the V-shaped, bead-like undercut 16 to the next wall of the spacing component 8.

An dieser Stelle wird darauf hingewiesen, daß die Schaltafel 2 auch ohne ausgeprägten Randbestandteil 10 ausgebildet sein kann. Man kann beispielsweise die beiden Randbestandteile 10 mit den beiden Schrägwänden 18 insgesamt weglassen. Oder man kann die randnächste Wand des Abstandsbestandteils 8 rechtwinklig zu dem Vorderbestandteil 4 und dem Rückbestandteil 6 verlaufen lassen.At this point it is pointed out that the formwork panel 2 can also be formed without a pronounced edge component 10. For example, the two edge components 10 with the two inclined walls 18 can be omitted altogether. Or one can let the wall of the spacer component 8 closest to the edge run at right angles to the front component 4 and the rear component 6.

Durch Fig. 3 wird die geschilderte Ausbildung der Schaltafel 2 mittels perspektivischer Darstellung nochmals veranschaulicht. Man erkennt außerdem ein Loch 20, welches durch gegenseitige Ergänzung aus zwei Halblöchern gebildet ist. Das Loch 20 ist zur Vorderseite der Schaltafel 2 und zur Rückseite der Schaltafel 2 offen und erstreckt sich rechtwinklig zur Ebene der Schaltafel 2.The illustrated design of the formwork panel 2 is illustrated again by means of a perspective illustration by FIG. 3. A hole 20 can also be seen, which is formed from two half-holes by mutual addition. The hole 20 is open to the front of the panel 2 and to the rear of the panel 2 and extends at right angles to the level of the panel 2.

In Fig. 4, links, ist eine bevorzugte Ausgestaltung dargestellt, bei der der gezeichnete Randbestandteil 10 aus einem Aluminiumprofil besteht. Das Aluminiumprofil weist im wesentlichen eine erste Wand 22, die mit etwas Abstand von dem Rand der Schaltafel 2 von deren Vorderbestandteil 4 zu deren Rückbestandteil 6 rechtwinklig verläuft, eine zweite Wand, die diagonal von dem vorderseitigen Rand der Schaltafel 2 zur Rückseite der Schaltafel 2 im Abstand von deren Rand verläuft, eine dritte Wand 26, die etwa von der Mitte der zweiten Wand 24 zu dem rückseitigen, verbreiterten Fuß 28 verläuft, sowie diesen rückseitigen, verbreiterten Fuß 28 auf. Die weiter vorn beschriebenen, geometrischen Verhältnisse, insbesondere rückseitige Rinne 12, Hinterschneidung 16 und seitliche, äußere Rinne 14 sind erhalten geblieben. Der Randbestandteil 10 ist vorzugsweise dadurch mit der restlichen Schaltafel 2 verbunden, daß seine zweite Wand 24 mit einer flächig anliegenden Schrägwand des Abstandsbestandteils 8 verklebt oder vernietet ist.In Fig. 4, left, a preferred embodiment is shown in which the drawn edge component 10 consists of an aluminum profile. The aluminum profile essentially has a first wall 22, which runs at a certain distance from the edge of the formwork panel 2 from its front component 4 to its back component 6, a second wall that diagonally from the front edge of the formwork panel 2 to the rear of the formwork panel 2 in Distance from the edge thereof, a third wall 26, which extends approximately from the center of the second wall 24 to the rear, widened foot 28, and this rear, widened foot 28. The geometric relationships described above, in particular the rear groove 12, the undercut 16 and the lateral outer groove 14 have been retained. The edge component 10 is preferably connected to the rest of the formwork panel 2 in that its second Wall 24 is glued or riveted to a flat inclined wall of the spacing component 8.

Wenn man eine Schaltafel 2 mit vier Randbestandteilen 10 und/oder mit einem allseitigen Verschluß der Hohlräume haben will, kann man insbesondere Randbestandteile 10 der in Fig. 4 gezeichneten Art auch an den beiden Stirnseiten der Schaltafel 2, nämlich hinter der Zeichnungsebene und vor der Zeichnungsebene, anbringen. Hierfür muß lediglich das extrudierte Gebilde aus Vorderbestandteil 4, Rückbestandteil 6 und Abstandsbestandteil 8 an beiden Stirnseiten schräg abgeschnitten werden.If you want to have a formwork panel 2 with four edge components 10 and / or with an all-round closure of the cavities, you can in particular edge components 10 of the type shown in FIG. 4 also on the two end faces of the formwork panel 2, namely behind the drawing plane and in front of the drawing plane , attach. For this purpose, only the extruded structure of front component 4, rear component 6 and spacer component 8 must be cut off obliquely on both end faces.

Fig. 5 veranschaulicht, wie zwei benachbarte Schaltafeln 2 durch ein Verbindungsschloß bzw. eine Verbindungsklammer fluchtend ausgerichtet stabil miteinander verklammert werden können. Das Verbindungsschloß 30 besteht im wesentlichen aus einem länglichen Basisteil 32 mit hohlrechteckigem Querschnitt, einem in dem Basisteil 32 aufgenommenen, länglichen, längs des Basisteils 32 verschiebbaren Keilelement 34 und zwei Klammerbacken 36 und 38. Der eine Klammerbacken 36 ist an dem Basisteil 32 starr befestigt. Der andere Klammerbacken 38 ist um eine Achse 40 schwenkbar, die sich zwischen den beiden Seitenwänden des Basisteils 32 erstreckt. Eine hintere Nase 42 des zweiten Klammerbackens 38 ist in Kontakt mit einer Schrägfläche 44 des Keilelements 34. Je weiter das Keilelement 34 in Fig. 5 nach rechts verschoben wird, desto stärker wird die zweite Klammerbacke 38 im Gegenuhrzeigersinn verschwenkt. Im in Fig. 5 dargestellten Schließzustand greift die vordere Nase des linken Klammerbackens 36 in die Hinterschneidung der linken Schaltafel 2 und greift die vordere Nase der zweiten Klammerbacke 38 in die Hinterschneidung der rechten Schaltafel 2. Wenn das Keilelement 34 in Fig. 5 weit nach links verschoben wird, kommt ein Vorsprung 46 des Keilelements 34 in Kontakt mit der rückseitigen Nase 42 der zweiten Klammerbacke 38 und schwenkt die zweite Klammerbacke 38 im Uhrzeigersinn in ihre völlig geöffnete Stellung.FIG. 5 illustrates how two adjacent formwork panels 2 can be stably aligned with one another by means of a connecting lock or a connecting bracket. The connecting lock 30 essentially consists of an elongated base part 32 with a hollow rectangular cross section, an elongated wedge element 34 accommodated in the base part 32 and displaceable along the base part 32, and two clamp jaws 36 and 38. The one clamp jaw 36 is rigidly attached to the base part 32. The other clamp jaw 38 is pivotable about an axis 40 which extends between the two side walls of the base part 32. A rear lug 42 of the second clamp jaw 38 is in contact with an inclined surface 44 of the wedge element 34. The further the wedge element 34 is displaced to the right in FIG. 5, the more the second clamp jaw 38 is pivoted counterclockwise. In the closed state shown in Fig. 5, the front nose of the left clamp jaw 36 engages in the undercut of the left panel 2 and engages the front nose of the second clamp jaw 38 in the undercut of the right panel 2. When the wedge element 34 is displaced far to the left in FIG. 5, a projection 46 of the wedge element 34 comes into contact with the rear nose 42 of the second Clamp jaw 38 and pivots the second clamp jaw 38 clockwise to its fully open position.

Das beschriebene Verbindungsschloß 30 stellt eine eigene Erfindung dar. Es kann auch zusammen mit nicht-erfindungsgemäßen Schaltafeln 2 technisch sinnvoll eingesetzt werden.The connection lock 30 described is a separate invention. It can also be used in a technically meaningful manner together with switch panels 2 not according to the invention.

Es wird darauf hingewiesen, daß die in Fig. 5 dargestellte Art der Verklammerung benachbarter Schaltafeln 2 keineswegs die einzig mögliche ist. Man kann beispielsweise auch mit konventionellen Verbindungsriegeln arbeiten, die an der Rückseite zweier benachbarter Schaltafeln auf beliebige Weise angesetzt und daran befestigt werden können. In diesem Fall ist es auch nicht erforderlich, daß die Schaltafeln 2 die Rinnen 12 und die Hinterschneidungen 16 aufweisen. Ferner wird darauf hingewiesen, daß bei entsprechender Ausbildung der Schaltafeln 2 Verbindungsschlösser, vorzugsweise Verbindungsschlösser 30 wie das in Fig. 5 gezeigte, an allen vier Rändern zur allseitigen Verklammerung benachbarter Schaltafeln 2 eingesetzt sein können.It is pointed out that the type of clamping of adjacent formwork panels 2 shown in FIG. 5 is by no means the only possible one. You can also work with conventional connecting bolts, for example, which can be attached to and attached to the back of two adjacent formwork panels in any way. In this case, it is also not necessary for the formwork panels 2 to have the channels 12 and the undercuts 16. Furthermore, it is pointed out that if the formwork panels are designed appropriately, 2 connection locks, preferably connection locks 30 such as that shown in FIG. 5, can be used on all four edges for all-round clamping of adjacent formwork panels 2.

In Fig. 6 ist veranschaulicht, wie ein mit Außengewinde versehener Stab 50 in ein vorstehend angesprochenes Loch 20 eingesetzt sein kann. Die Außenrinnen 14 geben genug Platz für den Stab 50 zwischen den rückseitigen Füßen 28 der Randbestandteile 10 und den vorderseitigen Materialverbreiterungen 52 der Randbestandteile 10. Ferner ist eine Flügelmutter 54 eingezeichnet, die mit dem Gewinde des Stabs 50 in Eingriff ist und sich an der Rückseite der beiden Füße 28 abstützt.FIG. 6 illustrates how an externally threaded rod 50 can be inserted into a hole 20 mentioned above. The outer channels 14 give enough space for the rod 50 between the rear Feet 28 of the edge components 10 and the front material broadening 52 of the edge components 10. Furthermore, a wing nut 54 is shown, which engages with the thread of the rod 50 and is supported on the back of the two feet 28.

In Fig. 7 ist eine Variante veranschaulicht, bei der der randnächste Hohlraum des Abstandsbestandteils 8 zusätzliche, längs verlaufende Wände 56 aufweist. Die Wände 56 erbringen dort eine zusätzliche Versteifung. Außerdem wird die Schaltafel 2 besser nagelbar.A variant is illustrated in FIG. 7, in which the cavity of the spacing component 8 closest to the edge has additional, longitudinal walls 56. The walls 56 provide additional stiffening there. In addition, the formwork panel 2 is easier to nail.

Fig. 8 veranschaulicht, daß erfindungsgemäße Schaltafeln 2 in unterschiedlicher Breite hergestellt werden können. Hierbei kann man nach einem Rastersystem vorgehen, indem der Abstandbestandteil 8 für die nächstbreitere Schaltafel 2 beispielsweise um zwei Hohlräume verbreitert wird und der Vorderbestandteil 4 sowie der Rückbestandteil 6 ebenfalls entsprechend verbreitert werden. Fig. 8 unten veranschaulicht eine Schaltafel 2 mit Winkelgestalt zum Betonieren einer rechtwinkligen Innenecke. Analog läßt sich eine Schaltafel 2 mit Winkelgestalt zum Betonieren einer Außenecke erstellen.Fig. 8 illustrates that formwork panels 2 according to the invention can be produced in different widths. Here, one can proceed according to a grid system in that the spacing component 8 for the next wider formwork panel 2 is widened, for example, by two cavities and the front component 4 and the rear component 6 are likewise widened accordingly. Fig. 8 below illustrates a formwork panel 2 with an angular shape for concreting a rectangular inner corner. Similarly, a formwork panel 2 with an angular shape can be created for concreting an outside corner.

Es wird darauf hingewiesen, daß die Vorderbestandteil-Wände, die Rückbestandteil-Wände und die Abstandsbestandteil-Wände nicht alle die gleiche Materialstärke haben müssen, wie es zeichnerisch dargestellt ist. Man kann zum Beispiel dem Vorderbestandteil 4 eine größere Wandstärke geben als dem Rückbestandteil 6 und dem Abstandsbestandteil 8. Außerdem ist es möglich, die Wandstärke innerhalb des jeweiligen Bestandteils zu variieren, beispielsweise im mittleren Bereich der Schaltafel 2 größere Wandstärken zu wählen als mehr zum Rand. Die gezeichneten Hohlräume 58 der Tragstruktur können mit Schaumkunststoff ausgeschäumt sein.It is pointed out that the front component walls, the rear component walls and the spacer component walls do not all have to have the same material thickness as shown in the drawing. For example, the front component 4 can be given a greater wall thickness than the rear component 6 and the spacing component 8. It is also possible to vary the wall thickness within the respective component, for example in the middle area of the formwork panel 2 choose larger wall thicknesses than more to the edge. The drawn cavities 58 of the support structure can be foamed with foam plastic.

Die Zeichnungsfiguren zeigen, daß die Randbestandteile 10 rückseitig mit dem Rückbestandteil 6 fluchten. Die erfindungsgemäßen Schaltafeln können gut parallelliegend aufeinander gestapelt werden, weil auch ihre Rückseite, gegebenenfalls mit Ausnahme der Rinnen 12, geschlossen ist. Wenn die Hohlräume 58 ausgeschäumt sind oder die beschriebenen Stirnseiten der Schaltafel 2 ebenfalls geschlossen sind, kann kein Beton in die Hohlräume 58 laufen.The drawing figures show that the edge components 10 are aligned on the back with the rear component 6. The formwork panels according to the invention can be stacked on top of one another in a good parallel manner, because their rear side is also closed, possibly with the exception of the channels 12. If the cavities 58 are foamed or the described end faces of the formwork panel 2 are also closed, no concrete can run into the cavities 58.

Wenn Randbestandteile 10 vorhanden sind, erbringen diese eine zusätzliche Versteifungswirkung. Deshalb ist es am sinnvollsten, wenn die Randbestandteile 10 mindestens in der Richtung verlaufend vorgesehen sind, in der die Schaltafel 2 länger ist als in der in den Zeichnungsfiguren erkennbaren Querrichtung. Übliche Abmessungen der Schaltafel 2 sind eine Breite bis 1 m oder sogar bis 1,5 m uns eine Dicke von 5 bis 10 cm. Die Länge der Schaltafel 2 ist praktisch beliebig wählbar, wobei in der Regel Längen bis etwa 3 oder 4 m in Frage kommen.If edge components 10 are present, these provide an additional stiffening effect. Therefore, it makes most sense if the edge components 10 are provided running at least in the direction in which the formwork panel 2 is longer than in the transverse direction which can be seen in the drawing figures. Usual dimensions of the formwork panel 2 are a width of up to 1 m or even up to 1.5 m and a thickness of 5 to 10 cm. The length of the formwork panel 2 can be chosen practically as desired, with lengths of up to approximately 3 or 4 m generally being considered.

Statt der gezeichneten und beschriebenen Längshohlkammerstruktur der Schaltafel 2 kann auch eine Struktur aus einer entsprechend dicken Verbundplatte bzw. Sandwichplatte gewählt werden, an der vorzugsweise zwei oder vier Randbestandteile 10 befestigt sind.Instead of the drawn and described longitudinal hollow chamber structure of the formwork panel 2, a structure can also be selected from a correspondingly thick composite panel or sandwich panel, to which two or four edge components 10 are preferably attached.
