Abstract
Description
Die Erfindung betrifft eine Schaltafel zum Einschalen von Betonmassen mit einem aus Hohlprofilen zusammengesetzten Metallrahmen der einen Absatz aufweist, der den Außenrand einer Platte bündig aufnimmt und abstützt.The invention relates to a formwork panel for encasing concrete masses with a metal frame composed of hollow profiles, which has a shoulder that receives and supports the outer edge of a plate flush.
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 Oberfläche baucht im Schraubenbereich oft aus. Ohne besondere Spachtelmaßnahmen sind die Tafeln aus Holz oberflächenstrukturiert, was insbesondere bei der Herstellung von Sichtbeton unerwünscht ist.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 will 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. The properties of the plywood panels limit the life of the formwork panel, screws tear out easily and the surface often bulges in the area of the screws. Without special filling measures, the wooden panels are surface-structured, which is particularly undesirable in the production of exposed concrete.
Aus der EP-A-0 146 844 und der LU-A-66 654 ist es bekannt, Schaltafeln aus Kunststoff herzustellen. Diese bekannten Schaltafeln weisen keinen umlaufenden Metallrahmen auf, so daß sie trotz der evtl. Verwendung versteifenden Einlagen relativ Biegeweich sind und daher die Schaltafeln beim Einsatz vielfach abgestützt werden müssen, was für die Aufstellung der Schalung sehr aufwendig ist. Aus der LU-A-66 654 ist es ferner noch bekannt, im Abstand parallel zueinander und im Abstand von den Oberflächen verlaufende Kanäle vorzusehen, in denen wenigstens zum Teil Verstärkungsstäbe eingesetzt sind. Diese Kanäle haben einen quadratischen Querschnitt. Bei Belastung treten in den Eckbereichen hohe Spannungsspitzen auf, die zur Rißbildung im Kunststoff führen, verbunden mit dem Nachteil, daß dann durch diese Risse Wasser eindringen und die Tafeln zerstören kann.From EP-A-0 146 844 and LU-A-66 654 it is known to manufacture switchboards from plastic. These known formwork panels have no circumferential metal frame, so that despite the possible use of stiffening inserts, they are relatively flexible and therefore the formwork panels have to be supported many times during use, which is very complex for the installation of the formwork. From LU-A-66 654 it is also known to provide channels running parallel to one another and at a distance from the surfaces, in which reinforcing bars are at least partially inserted. These channels have a square cross section. When loaded, high stress peaks occur in the corner areas, which lead to the formation of cracks in the plastic, combined with the disadvantage that water can then penetrate through these cracks and destroy the panels.
Aus der EP-A3-l46 844 ist es bekannt, den Kunststoff durch Gewebe oder Fasern zu verstärken. Diese bekannten Kunststoffplatten werden durch Pressen hergestellt, was komplizierte und relativ teuere Formen und insbesondere große leistungsstarke Pressen erfordert.From EP-A3-146 844 it is known to reinforce the plastic with fabrics or fibers. These known plastic sheets are manufactured by pressing, which requires complicated and relatively expensive forms and in particular large, powerful presses.
In Vermeidung der geschilderten Nachteile liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Schaltafel der eingangs genannten Art so auszubilden, daß mit relativ einfachen Werkzeugen eine formbeständige Schaltafel hoher Belastbarkeit erhalten wird.In avoiding the disadvantages described, the present invention is based on the object of designing a formwork panel of the type mentioned at the outset in such a way that a form-stable formwork panel of high load-bearing capacity is obtained with relatively simple tools.
Zur Lösung dieser Aufgabe sieht die Erfindung vor, daß die Platte aus Kunststoff, vorzugsweise PVC besteht, daß der Kunststoff durch Naturfasern, Mineralfasern, Glasfasern und/oder Metallfasern in Form von Fäden, Fadenstücken, Geweben, Gewebestücken und/oder Vlies verstärkt ist, wobei die Länge der Fadenstücke zwischen etwa fünf und fünfzehn Millimeter liegt, daß ferner die Platte im Abstand parallel zueinander und im Abstand von der Plattenoberfläche verlaufende Kanäle aufweist, daß diese Kanäle etwa einen Kreis- oder Ellipsenquerschnitt haben, und daß wenigstens in einem Teil der Kanäle Verstärkungsstäbe vorgesehen sind und daß die Platte aus Plattenstreifen zusammengesetzt ist und daß diese Plattenstreifen durch Extrusion hergestellt sind, daß ferner die Plattenstreifen im Querschnitt seitliche Vorsprünge und Aussparungen aufweisen für eine nut- und federartige oder schwalbenschwanzartige Verbindung der Plattenstreifen.To achieve this object, the invention provides that the plate is made of plastic, preferably PVC, that the plastic is reinforced by natural fibers, mineral fibers, glass fibers and / or metal fibers in the form of threads, pieces of thread, fabrics, pieces of tissue and / or fleece, wherein the length of the thread pieces is between about five and fifteen millimeters, further that the plate has channels parallel to one another and at a distance from the surface of the plate, that these channels have approximately a circular or elliptical cross section, and that reinforcing bars are present in at least some of the channels are provided and that the plate is composed of plate strips and that these plate strips are produced by extrusion, that the plate strips also have cross-sectional projections and recesses for a tongue and groove or dovetail connection of the plate strips.
Eine Erhöhung der Biegefestigkeit und damit der möglichen Belastbarkeit kann dadurch erreicht werden, daß das Vlies oder Gewebe nahe unter den Oberflächen der Platte im Kunststoff eingebettet ist.An increase in the bending strength and thus the possible resilience can be achieved in that the fleece or fabric is embedded in the plastic near the surface of the plate.
Dadurch daß die Fasern- oder Gewebeschnitzel in den Kunststoff eingemischt und die Platten durch Extrudieren hergestellt werden, erfolgt eine gewisse Ausrichtung der Fasern oder Federn beim Extrudieren, so daß die mechanische Eigenschaften der Platten in Richtung der Extrusion anders sind, als quer dazu. Zum Ausgleich könnten die Gewebe ihn Extrusionsrichtung weniger oder dünnere Federn oder Drähte aufweisen als quer dazu, um hier wieder symmetrische Eigenschaften zu erreichen, bei Beibehaltung der besonders günstigen Extrusionsverfahrens.Because the fiber or fabric chips are mixed into the plastic and the plates are produced by extrusion, there is a certain alignment of the fibers or Springs during extrusion, so that the mechanical properties of the plates in the direction of the extrusion are different than in the transverse direction. To compensate for this, the fabrics could have fewer or thinner springs 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.
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 symmetrison zu ihrer Mittelebene ausgebildet, so daß durch Wenden der Platten eine weitere Ernohung der Gebrauchsdauer erzielbar ist. Die Plattendicke kann bei geringem Gewicht kleingehalten werden, wenn die Rahmen aus einem Honlprofil bestehen, wobei eine saubere Betonoberfläche ohne Randabdruck erzielt 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 symmetrical to their central plane, so that a further increase in the service life can be achieved by turning the plates. The panel thickness can be kept small with a low weight if the frames consist of a honing profile, whereby a clean concrete surface without an edge impression can be achieved if the hollow profile has a shoulder through which the outer edge of the panel is received flush. This also ensures particularly good protection of the softer plate edge against damage.

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
Zur Material- und Gewichtseinsparung sind in Extrusionsrichtung parallele Kanäle im Platteninneren vorgesehen, wie dies in Figur 4 angedeutet ist. Die Kanäle 13 können Kreisquerschnitt oder wie dargestellt, einen Elipsenquerschnitt aufweisen. Zur Erhöhung der Biegesteifigkeit sind in einzelne oder alle Kanäle 13 Verstärkungsstreben 14 in Form von Metallstäben oder Rohren eingesetzt. Die Verstärkungsstreben 14 können aber auch aus glasfaserverstärktem Material hergestellt sein.To save material and weight, parallel channels are provided in the interior of the plate in the direction of extrusion, as indicated in FIG. The
Um rationell Schaltafeln 1 verschiedener Abmessungen herstellen zu ist vorteilhaft die Platte 5 aus Plattenstreifen 15 zusammengesetzt. Diese weisen an ihren Längsseiten einerseits einen Vorsprung 16 und andererseits eine Aussparung 17 auf, 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 rationally produce formwork panels 1 of different dimensions, the
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
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
