Description

Die Erfindung betrifft eine Schaltafel mit einer von einem Rahmen aus Holz und/oder Metall abgestützten und/oder verstärkten Platte, die dem Einschalen von Betonmassen dient.The invention relates to a formwork panel with a plate which is supported and / or reinforced by a frame made of wood and / or metal and which is used for formwork encasing.

Bei einer aus der DE-PS 28 48 154 bekannten Schaltafel besteht die Platte aus Sperrholz. Neben dem relativ hohen Preis hat Sperrholz den Nachteil des Aufquellens bei eindringender Feuchtigkeit. Bei starker Beanspruchung fasert die Oberfläche der Platten auf. Durch eventuell notwendig werdende Bohrungen kann in das Platteninnere Feuchtigkeit eindringen, was zum Aufquellen der Platte führen kann, so daß keine sauberen Betonflächen mehr erreicht werden können. Durch die Eigenschaften der Platten aus Sperrholz ist die Lebensdauer der Schaltafel beschränkt, Schrauben reißen leicht aus und die Oberfäche baucht im Schraubenbereich oft aus.In a formwork panel known from DE-PS 28 48 154, the plate consists of plywood. In addition to the relatively high price, plywood has the disadvantage of swelling when moisture penetrates. In the case of heavy use, the surface of the panels fray. Any holes that may become necessary can allow moisture to penetrate the inside of the slab, which can cause the slab to swell, so that clean concrete surfaces can no longer be reached. Due to the properties of the plywood panels, the life of the formwork panel is limited, screws tear out easily and the surface often bulges in the screw area.

Es ist bekannt, Schaltafeln vollständig aus Metall herzustellen, dann ist aber kein Nageln mehr möglich, so daß Schalungseinsätze für eventuelle Aussparungen und Durchbrüche nicht mehr mit vertretbarem Aufwand ordnungsgemäß befestigt werden können. Auch lassen sich Metalloberflächen relativ schlecht von Betonrückständen reinigen wenn diese ausgehärtet sind.It is known to produce formwork panels completely from metal, but then nailing is no longer possible, so that formwork inserts for possible recesses and openings can no longer be properly attached with reasonable effort. Metal surfaces are also relatively difficult to clean from concrete residues once they have hardened.

In Vermeidung der geschilderten Nachteile liegt der vorliegenden Erfindung die Aufgabe zugrunde eine Schaltafel der eingangs genannten Art so zu verbessern, daß bei langer Lebensdauer Feuchtigkeit praktisch ohne Einfluß auf die Maßhaltigkeit ist, wobei die Möglichkeit des Nagelns und Schraubens im Bereich der Platten erhalten bleiben soll und die Schaltafel beim Entschalen leicht ablosbar, schmutzabweisend und damit leicht reinigbar sein sollen.In avoiding the disadvantages, the object underlying the present invention is based, a formwork panel of the aforementioned type to improve so that a long service life moisture is practically without influence on the dimensional accuracy, the possibility of nailing and screwing to be retained in the area of the plates and the formwork panel should be easy to remove, dirt-repellent and therefore easy to clean when demoulding.

Zus Lösung dieser Aufgabe sieht die Erfindung vor, daß die Platte aus Kunststoff vorzugsweise aus PVC besteht. Auch Polyäthylen wäre zur Verwendung geeignet, ist aber gegenüber PVC wesentlich teurer, aber verschleißfester.To achieve this object, the invention provides that the plate made of plastic preferably consists of PVC. Polyethylene would also be suitable for use, but is much more expensive than PVC, but more wear-resistant.

Zur Erhöhung der Festigkeit, insbesondere der Langzeitstandfestigkeit kann in besonders vorteilhafter Weise der Kunststoff durch Fasern verstärkt sein. Hierzu können Fadenstücke und/oder Gewebeschnitzel dienen, wobei die Fadenstücke zur Erleichterung der Verarbeitung etwa zwischen 5 und 15 mm lang sein können.To increase the strength, in particular the long-term stability, the plastic can be reinforced with fibers in a particularly advantageous manner. Thread pieces and / or tissue chips can be used for this purpose, the thread pieces being able to be approximately between 5 and 15 mm long to facilitate processing.

Als Faserverstärkung können in vorteilhafter Weise auch Gewebe aus Natur-, Mineral-, insbesondere Glas-, Kunststoff- und/oder Metall-Fasern oder Fäden dienen. Anstelle der Verwebung können auch Vliesmatten aus den genannten Materialien verwendet werden. Eine besonders hohe Belastbarkeit kann bei geringem Gewicht durch die Verwendung von Kohlefasern erreicht werden. Bei möglichst geringem Werkstoffaufwand kann eine optimale Festigkeitserhöhung dadurch erreicht werden, daß das Vlies oder die Gewebe nahe unter den Oberflächen der Platten im Kunststoff eingebettet sind, so daß durch die geschlossene Kunststoffoberfläche eine glatte, leicht reinigbare, schmutzabweisende Fläche erhalten bleibt, so daß kein Schalöl oder Trennmittel zur Erleichterung des Ausschalens verwendet werden muß und damit ein umweltschonender Einsatz ermöglicht wird.Fabrics made from natural, mineral, in particular glass, plastic and / or metal fibers or threads can also advantageously serve as fiber reinforcement. Instead of weaving, you can also use fleece mats from the mentioned materials are used. A particularly high load capacity can be achieved with low weight by using carbon fibers. With as little material expenditure as possible, an optimal increase in strength can be achieved in that the fleece or the fabric is embedded in the plastic near the surface of the plates, so that the smooth plastic surface maintains a smooth, easy-to-clean, dirt-repellent surface, so that no formwork oil or release agents must be used to make it easier to remove formwork and thus enable environmentally friendly use.

Zur einfachen Herstellung können die Fasern oder Gewebeschnitzel in den Kunststoff eingemischt und die Platten durch Extrudieren hergestellt sein. Durch das Extrudiern erfolgt eine gewisse Ausrichtung der Fasern oder Fäden, so daß die mechanischen Eigenschaften der Platte in Richtung der Extrusion anders sind als quer dazu. Zum Ausgleich können die Gewebe in Extrusionsrichtung weniger oder dünnere Fäden oder Drähte aufweisen als quer dazu, um hier wieder symmetrische Eigenschaften zu erreichen bei Beibehaltung des besonders günstigen Extrusionsverfahrens.For easy production, the fibers or tissue chips can be mixed into the plastic and the plates can be produced by extrusion. The extrusion results in a certain orientation of the fibers or threads, so that the mechanical properties of the plate in the direction of the extrusion are different than at right angles to it. To compensate, the fabrics can have fewer or thinner threads or wires in the direction of extrusion than transversely to them, in order to achieve symmetrical properties again while maintaining the particularly favorable extrusion process.

Vorteilhaft ist noch, daß Beschädigungen der Plattenoberfläche durch Spachteln leicht an Ort und Stelle reparierbar sind und daß ferner unbrauchbar gewordene Platten nach einer Zerkleinerung zur Herstellung neuer Platten wieder verwendet werden können.Another advantage is that damage to the The surface of the plate can be easily repaired on the spot by filling and that plates which have become unusable can also be reused after being shredded to produce new plates.

Zur rationalen Herstellung von Schaltafeln unterschiedlicher Abmessungen können die Platten aus Plattenstreifen zusammengesetzt sein, wobei dann die Plattenstreifen durch Extrusion hergestellt sind. Zur einfachen maßgenauen Verbindung können die Plattenstreifen im Querschnitt seitlich Vorsprünge und Aussparungen aufweisen für eine nut- und federartige oder schwalbenschwanzartige Verbindung der Plattenstreifen. Die Plattenstreifen können bei einer nut- und federartigen Verbindung einfach durch Zusammensetzen miteinander verklebt und verschweißt werden, während bei einer schwalbenschwanzartigen Verbindung das Zusammensetzen zu Platten durch das erforderliche Einschieben, etwas aufwendiger ist, aber nicht unbedingt eine Verklebung oder Verschweißung erforderlich macht.For the rational production of formwork panels of different dimensions, the panels can be composed of panel strips, the panel strips then being produced by extrusion. For a simple, dimensionally accurate connection, the plate strips can have lateral projections and recesses in cross section for a tongue and groove or dovetail-like connection of the plate strips. The plate strips can be glued and welded together simply by assembling a tongue and groove connection, while assembling to plates by a required dovetail connection is somewhat more complex, but does not necessarily require gluing or welding.

Zur Gewichts- und Materialeinsparung können die Platten im Abstand parallel zueinander und im Abstand von den Plattenoberflächen verlaufende Kanäle aufweisen, die vorzugsweise einen Kreis- oder Elipsenquerschnitt haben können. Zur Erhöhung der Belastbarkeit können wenigstens in einem Teil der Kanäle Verstärkungstäbe eingesetzt sein. Die Verstärkungsstäbe selbst können wiederum Hohlprofile sein.To save weight and material, the plates can have channels running parallel to one another and at a distance from the plate surfaces, which can preferably have a circular or elliptical cross section. To increase the load capacity, reinforcing bars can be used in at least some of the channels. The reinforcing bars themselves can in turn be hollow profiles.

In vorteilhafter Weise kann zur Erleichterung des Ausschalens und zum Reinigen der Schaltafeln die Oberflächen der Platten mit einer Schicht aus Polytetraflouräthylen (Teflon) versehen sein.The surfaces of the plates can advantageously be provided with a layer of polytetrafluoroethylene (Teflon) in order to make it easier to remove formwork and to clean the formwork panels.

Die Platten sind vorzugsweise symmetrisch zu ihrer Mittelebene ausgebildet, so daß durch Wenden der Platten eine weitere Erhohung der Gebrauchsdauer erzielbar ist. Die Plattendicke kann bei geringem Gewicht kleingehalten werden, wenn die Rahmen aus einem Hohlprofil bestehen, wobei eine saubere Betonoberfläche ohne Randabdruck erzeilt werden kann, wenn das Hohlprofil einen Absatz aufweist, durch den der Außenrand der Platte bündig aufgenommen ist. Hierdurch erfolgt gleichzeitig ein besonders guter Schutz der weicheren Plattenkante gegen Beschädigungen.The plates are preferably formed symmetrically to their central plane, so that a further increase in the service life can be achieved by turning the plates. The plate thickness can be kept small with a low weight if the frames consist of a hollow profile, and a clean concrete surface can be achieved without an edge impression if the hollow profile has a shoulder through which the outer edge of the plate is received flush. This also ensures particularly good protection of the softer plate edge against damage.

Weitere erfindungsgemäße Ausbildungen sind den Unteransprüchen zu entnehmen und werden mit ihren Vorteilen in der nachstehenden Beschreibung näher erläutert. In den beigefügten Zeichnungen zeigt

  • Figuren 2 bis 6 Teilschnitte durch verschiedene Ausführungen von Platten der Schaltafel.
Further designs according to the invention can be found in the subclaims and their advantages are explained in more detail in the description below. In the accompanying drawings
  • 1 shows a partial section through a formwork panel
  • Figures 2 to 6 partial sections through different versions of panels of the formwork panel.

Die in Figure 1 im Teilquerschnitt dargestellte Schaltafel 1 besteht aus einem Metallrahmen 2, einem Hohlprofil 3, das einen Absatz 4 aufweist, in dem eine Platte 5 bündig zu ihrer Oberfläche 6 eingesetzt ist. Dabei liegt der Außenrand 7 der Platte 5 am Vorsprung 8 des Absatzes 4 dicht an, wobei zur Überbrückung eventueller Toleranzen der Absatz 4 etwas nach unten und seitlich, einen L-förmigen Freiraum 9 bildend, ausgeformt ist. Die Dicke der Platte 5 entspricht dabei der Höhe des Vorsprungs 8, so daß die Oberfläche 6ʹ mindestens auf dem Kantenbereich 10 des Absatzes voll aufliegt.The panel 1 shown in Figure 1 in partial cross section consists of a metal frame 2, a hollow profile 3, which has a shoulder 4, in which a plate 5 is inserted flush with its surface 6. The outer edge 7 of the plate 5 lies tightly against the projection 8 of the shoulder 4, the shoulder 4 being formed somewhat downward and laterally to bridge any tolerances, forming an L-shaped free space 9. The thickness of the plate 5 corresponds to the height of the projection 8, so that the surface 6ʹ at least fully rests on the edge region 10 of the paragraph.

Die Platte 5 selbst ist in bekannter Weise an nicht dargestellten Querstreben des Metallrahmens 2 über Schrauben befestigt.The plate 5 itself is fastened in a known manner to cross struts, not shown, of the metal frame 2 by means of screws.

Die in Figur 1 dargestellte Platte 5 besteht aus Kunststoff und zwar aus PVC (Polyvenylchlorid). Zur Erhöhung der Standzeit bei Dauerbeanspruchung sind dem Kunststoff Fasern 11 beigemischt, bspw. Textilfasern, Glasfasern oder zur besonderen Erhöhung der Festigkeit Kohlefasern. Es können aber auch Metallfasern oder auch Fäden verwendet werden.The plate 5 shown in Figure 1 is made of plastic, namely PVC (polyvinyl chloride). Fibers 11 are mixed into the plastic, for example textile fibers, glass fibers or, to increase the strength in particular, carbon fibers to increase the service life in the event of continuous use. However, metal fibers or threads can also be used.

Zur Erleichterung der Herstellung der Platten 5, insbesondere durch Extrudieren, sind die Fasern oder Fäden von begrenzter Länge. Faser- bzw. Fädenlängen zwischen etwa 5 und 15 mm haben ein Optimum zwischen Verarbeitbarkeit und Festigkeitssteigerung ergeben.In order to facilitate the production of the plates 5, in particular by extrusion, the fibers or threads are of limited length. Fiber or thread lengths between about 5 and 15 mm have resulted in an optimum between workability and strength increase.

Zur weiteren Erhöhung der Belastbarkeit der Platten 5 können nahe unter den Oberflächen 6, 6ʹ Gewebe 12 aus textilen Werkstoffen Glasfasern oder auch Metalldrähten eingebettet sein, wie dies in Figur 2 dargestellt ist.In order to further increase the load-bearing capacity of the plates 5, glass fibers or metal wires can be embedded close to the surfaces 6, 6ʹ, fabric 12 made of textile materials, as shown in FIG. 2.

Bei der Herstellung der Platten 5 durch Extrusion erfolgt eine gewisse Ausrichtung der in das Material eingebetteten Fasern, so daß bei einer Plattenbelastung der Verformung abhängig von der Extrusionsrichtung ist. Um hier in allen Richtungen gleiche Durchbiegeverformungen bei Plattenbelastung zu erreichen, können asymmetrische Gewebe verwendet werden, bei denen quer zur Extrusionsrichtung mehr Fäden vorgesehen sind als in Extrusionsrichtung, wie dies in Figur 3 angedeutet ist. Hier kommen auf jeden Kettfaden zwei Schußfäden. Ein Ausgleich kann aber auch durch Verwendung unterschiedlicher Faden- oder Drahtstärken erreicht werden.When the plates 5 are produced by extrusion, there is a certain alignment of the fibers embedded in the material, so that when the plates are loaded, the deformation depends on the direction of extrusion. In order to achieve the same bending deformations in all directions when loading the plate, asymmetrical fabrics can be used in which more threads are provided transversely to the direction of extrusion than in the direction of extrusion, as indicated in FIG. 3. Here there are two weft threads on each warp thread. Compensation can also be achieved by using different thread or wire sizes.

Zur Material- und Gewichtseinsparung können in Extrusionsrichtung parallele Kanäle im Platteninneren vorgesehen sein, wie dies in Figur 4 angedeutet ist. Die Kanäle 13 können Kreisquerschnitt oder wie dargestellt, einen Elipsenquerschnitt aufweisen. Zur Erhöhung der Biegesteifigkeit können in einzelne oder alle Kanäle 13 Verstärkungsstreben 14 in Form von Metallstäben oder Rohren eingesetzt sein. Die Verstärkungsstreben 14 können aber auch aus glasfaserverstärktem Material hergestellt sein.In order to save material and weight, parallel channels can be provided in the interior of the plate in the direction of extrusion, as indicated in FIG. The channels 13 can have a circular cross section or, as shown, an elliptical cross section. To increase the bending stiffness, reinforcing struts 14 in the form of metal rods or can be placed in individual or all channels 13 Tubes may be used. The reinforcing struts 14 can also be made of glass fiber reinforced material.

Um rationell Schaltafeln 1 verschiedener Abmessungen herstellen zu können kann besonders vorteilhaft die Platte 5 aus Plattenstreifen 15 zusammengesetzt sein. Diese können dann an ihren Längsseiten einerseits einen Vorsprung 16 und andererseits eine Aussparung 17 aufweisen, bspw. wie in Figur 4 dargestellt in Schwalbenschwanzform oder wie in Figur 5 dargestellt in Form einer Feder 16ʹ und einer Nut 17ʹ.In order to be able to produce formwork panels 1 of different dimensions efficiently, the panel 5 can be composed of panel strips 15 in a particularly advantageous manner. These can then have on their long sides on the one hand a projection 16 and on the other hand a recess 17, for example. As shown in FIG. 4 in the form of a dovetail or as shown in FIG. 5 in the form of a tongue 16ʹ and a groove 17ʹ.

Die Verbindung kann aber auch gemäß Figur 6 durch zwei Längsnuten 18 und einen eingelegten im Querschnitt etwa rechteckförmigen Materialstreifen 19 gebildet sein.However, the connection can also be formed according to FIG. 6 by two longitudinal grooves 18 and an inserted material strip 19 which is approximately rectangular in cross section.

Zur Verbesserung der Verbindung kann die Feder 16ʹ mit der Nut 17ʹ bzw. der Materialstreifen 19 in den Längsnuten 18 verklebt sein.To improve the connection, the spring 16ʹ can be glued to the groove 17ʹ or the material strip 19 in the longitudinal grooves 18.

Zur Erleichterung der Entschalung und auch der Reinigung können die Oberflächen 6, 6ʹ mit einer Teflonbeschichtung versehen sein, so daß kein Schalöl verwendet werden muß.To facilitate the formwork removal and cleaning, the surfaces 6, 6ʹ can be provided with a Teflon coating, so that no formwork oil has to be used.

Die Härte des Kunststoffwerkstoff ist so eingestellt, daß in die Platten 5 Nägel oder Schrauben eingetrieben werden können.The hardness of the plastic material is set so that 5 nails or screws can be driven into the plates.
