Description

Schalungselement  An element
Die vorliegende Erfindung betrifft ein Schalungselement für Betonbauten, mit einem Grundkörper in Hohlprofilbauweise, der eine als Schalhaut ausgebildete Außenseite aufweist. The present invention relates to a formwork element for concrete structures, with a base body in hollow profile construction, which has a formwork facing outer side.
Stand der Technik State of the art
Einsatzbereite Schalungselemente weisen einen Grundkörper auf, an welchem in der Regel weitere Anbauelemente, wie beispielsweise Dichtelemente, angeordnet sind und werden für Schalungen verwendet, in die Frischbeton zur Herstellung von Betonbauteilen, wie etwa Wänden, Decken und dergl., eingebracht wird. Für diese Arbeiten müssen die Schalungselemente insbesondere in unterschiedlichen Breiten zur Verfügung stehen, was zu insgesamt hohen Fertigungskosten führt. Ready-to-use formwork elements have a base body, on which usually other attachments, such as sealing elements, are arranged and are used for formwork, in the fresh concrete for the production of concrete components, such as walls, ceilings and the like., Is introduced. For this work, the formwork elements must be available in particular in different widths, resulting in high overall manufacturing costs.
Die Aufgabe der Erfindung besteht darin, ein Schalungselement der eingangs genannten Art derart weiterzubilden, dass sich dessen Herstellung auf kostengünstigere Weise bewerkstelligen lässt. Vorteile der Erfindung The object of the invention is to develop a formwork element of the type mentioned in such a way that its manufacture can be accomplished in a cost effective manner. Advantages of the invention
Diese Aufgabe wird erfindungsgemäß durch ein Schalungselement mit den Merkmaien von Anspruch 1 gelöst. This object is achieved by a formwork element with the Merkmaien of claim 1.
Erfindungsgemäß ist der Grundkörper des Schalungselements zumindest aus zwei ineinandergreifenden Teilsegmenten gebildet, die an ihren ineinandergreifenden Randbereichen dauerhaft miteinander verbunden sind. According to the invention, the main body of the formwork element is formed at least from two intermeshing subsegments, which are permanently connected to one another at their intermeshing edge regions.
Der mit der Erfindung verbundene Vorteil besteht im Wesentlichen darin, dass eine Vielzahl unterschiedlich breiter Schalungselemente mit nur wenigen standardisierten Teilsegmenten auf einfache und kostengünstige Weise gefertigt werden kann. Die Hohlprofilbauweise des Grundkörpers erlaubt zudem bei entsprechender Auslegung der Verbindung der einzelnen Teilsegmente, die beispielsweise durch Niete erfolgen kann, einen derart robusten Aufbau des Schalungselements, dass insbesondere auch hohe angreifende Querkräfte weitgehend verformungsfrei aufgenommen werden können. The advantage associated with the invention consists essentially in the fact that a plurality of differently wide shuttering elements can be manufactured with only a few standardized sub-segments in a simple and cost-effective manner. The hollow profile construction of the body also allows, with appropriate design of the connection of the individual sub-segments, which can be done for example by rivets, such a robust construction of the formwork element that in particular high high transverse forces can be absorbed largely free of deformation.
Der Grundkörper des Schaiungselements ist vorzugsweise aus stranggepresstem Leichtmetall gefertigt, wodurch eine Herstellung auch komplizierter Hohlprofilformen in nur einem Verfahrensschritt auf kostengünstige Weise ermöglicht ist. Die im Verhältnis zur Gesamtbreite des Schalungselements bzw. des Grundkörpers geringere Breite der Teilsegmente erlaubt dabei eine Fertigung auf den am Markt in großer Anzahl verfügbaren Strangpresseinrichtungen, so dass die Notwendigkeit einer Fertigung auf kostenintensiven Sonderstrangpressen ersatzlos entfällt. The main body of the lining element is preferably made of extruded light metal, whereby a production of even complicated hollow profile shapes in only one step in a cost-effective manner is possible. The smaller width of the subsegments in relation to the overall width of the formwork element or of the base body permits production on the large number of available extrusion presses on the market, so that the need for production on costly special extruders is eliminated without replacement.
Aufgrund des sortenreinen Leichtmetall-Aufbaus des Grundkörpers kann dieser zudem problemlos in den Wertstoffkreislauf rückgeführt werden, womit insbesondere umweltbezogenen sowie wirtschaftlichen Aspekten Rechnung getragen ist. Due to the unmixed light metal structure of the body this can also be easily recycled into the recycling cycle, which is particularly environmental and economic aspects taken into account.
Die Teilsegmente sind nach einer besonders bevorzugten Ausführungsform der Erfindung miteinander verhakt, wodurch nicht nur eine einfache und schnelle The sub-segments are hooked together according to a particularly preferred embodiment of the invention, whereby not only a simple and fast
Montage des Schaiungselements, sondern auch ein hohes Maß an Bediensicherheit über die gesamte Lebensdauer des Schalungselements gewährleistet ist. Die Teilsegmente können als Rand- und/oder als Zwischensegmente ausgebildet sein. Dadurch kann der Grundkörper des Schalungselements lediglich zwei jeweils als Randsegment ausgebildete Teilsegmente aufweisen oder aber wenigstens ein zusätzliches Zwischensegment aufweisen, das zwischen den Randsegmenten angeordnet ist. Die Randsegmente weisen dabei nur einen Randbereich auf, der mit einem anderen Teilsegment, d.h. einem anderen Rand- oder einem Assembly of the Schaiungselements, but also a high degree of operating safety over the entire life of the formwork element is ensured. The sub-segments may be formed as edge and / or as intermediate segments. As a result, the basic body of the formwork element can have only two subsegments each formed as an edge segment or at least have an additional intermediate segment which is arranged between the edge segments. The edge segments in this case have only one edge region, which with another sub-segment, ie another edge or a
Zwischensegment, zu einem Schalungseiement (Grundkörper) dauerhaft verbindbar bzw. verhakbar ist. Intermediate segment, permanently connectable or hookable to a shuttering element (base body).
Die Randsegmente weisen zur lösbaren Verbindung des Schalungselements mit einem anderen Schalungssegment in ihrem Außenrandbereich insbesondere Schlossstreben und/oder halbkreisförmige Ankerlöcher auf. The edge segments have for releasable connection of the formwork element with another formwork segment in its outer edge region in particular struts struts and / or semicircular anchor holes.
Zwecks eines möglichst großen Einsatzspektrums des Schalungselements können die Rand- und/oder Zwischensegmente insbesondere eine unterschiedliche Breite aufweisen. Dadurch können Schalungselemente mit fein abgestuften Breitenmaßen kostengünstig zur Verfügung gestellt werden, wobei die Schalungselemente in Abhängigkeit von den zur Verfügung stehenden Breiten der Rand- und For the purpose of the widest possible range of use of the shuttering element, the edge and / or intermediate segments may in particular have a different width. As a result, formwork elements with finely graduated width dimensions can be provided inexpensively, wherein the formwork elements in dependence on the available widths of the edge and
Zwischensegmente entweder aus einer geringen oder aber aus einer höheren Anzahl von Teilsegmenten aufgebaut sein können. Intermediate segments can be constructed either of a low or of a higher number of sub-segments.
Nach einer besonders bevorzugten Weiterbildung der Erfindung weist die According to a particularly preferred embodiment of the invention, the
Hakverbindung Hakelemente auf, die an den Teilsegmenten ausgeformt sind. Hakverbindung hooking elements, which are formed on the sub-segments.
Hierdurch werden die Fertigungskosten des Teilsegments insgesamt verringert und die Montage der Teilsegmente vereinfacht. As a result, the manufacturing costs of the sub-segment are reduced overall and simplifies the assembly of the sub-segments.
Die Oberflächengüte sowie die Maßhaltigkeit des herzustellenden Betonelements hängen in entscheidender Weise von einer möglichst geringen relativen The surface quality and the dimensional stability of the concrete element to be produced depend in a decisive manner on the lowest possible relative
Verschiebung der Teilsegmente des Schalungselements bzw. von dem Grad der Verformung des Schalungselements unter den Frischbetonlasten ab. So können bereits kleine Relativbewegungen der Teüsegmente in ihrem Stoßbereich der Schalhaut zu einem schlechten, optischen Ergebnis der Oberflächenstruktur des Betonbauteils führen und eine aufwändige Nachbearbeitung des Betonbauteils erforderlich machen. Die Hakverbindung ist daher vorzugsweise an der Außen- und an einer Innenseite des Grundkörpers ausgebildet. Dadurch können einerseits die von dem Frischbeton auf das Schalelement ausgeübten Kräfte bevorzugt in diejenigen Bereiche der Teilsegmente eingeleitet werden, die im Hinblick auf das Lastaufnahmevermögen des Schalungselements eine ohnehin ausreichend große Materialstärke aufweisen müssen. Andererseits kann die Hakverbindung auf besonders einfache Weise auf eine Übertragung von Kraftkomponenten zwischen den miteinander verhakten Teilsegmenten ausgerichtet werden, die parallel und senkrecht zur Schalhaut des Schalungssegments wirken. Displacement of the sub-segments of the formwork element or from the degree of deformation of the formwork element under the fresh concrete loads. Thus even small relative movements of the Teüsegmente in their joint area of the formwork skin can lead to a poor, optical result of the surface structure of the concrete component and make a costly reworking of the concrete component required. The Hakverbindung is therefore preferably on the outside and formed on an inner side of the main body. As a result, on the one hand, the forces exerted by the fresh concrete on the formwork element can preferably be introduced into those regions of the subsegments which, in view of the load-bearing capacity of the formwork element, must have an already sufficiently large material thickness. On the other hand, the Hakverbindung can be aligned in a particularly simple manner to a transfer of force components between the interlocked sub-segments, which act parallel and perpendicular to the formwork skin of the shuttering segment.
Die Hakverbindung weist dabei vorzugsweise wenigstens einen, vorzugsweise im Bereich der Außenseite des Grundkörpers, an dem einen Teilsegment angeordneten Schnapphaken auf, der mit einem an dem anderen Teilsegment angeordneten Rastelement verrastet ist. In this case, the hook connection preferably has at least one snap hook, which is preferably arranged in the region of the outside of the base body, on the snap-in hook arranged on one subsegment and which is latched with a latching element arranged on the other subsegment.
Zwecks einer möglichst hohen Stabilität der Hakverbindung gegenüber orthogonal auf die Schalfläche einwirkenden Kräften stützt sich das den Schnapphaken aufweisende Teilsegment vorzugsweise mit seinem Innen- und/oder For the purpose of the highest possible stability of the hook connection with respect to orthogonal forces acting on the scarf surface, the sub-segment having the snap hook is preferably supported by its inside and / or outside

Außenwandabschnitt des jeweilig anderen Teilsegments ab. Dadurch wird der Schnapphaken auf einfache Weise gegenüber einem Abrutschen aus seiner verrasteten Position geschützt, wobei zugleich eine Flächenpressung zwischen einer Haltefläche des Schnapphakens und einer Hintergriffsfläche des Rastelements bei orthogonal zur Schalhaut wirkenden Kräften bewirkt wird. Diesbezüglich weist das eine Teilsegment nach einer Weiterbildung der Erfindung insbesondere eine Outside wall section of the respective other subsegment from. As a result, the snap hook is easily protected against slipping out of its locked position, wherein at the same time a surface pressure between a holding surface of the snap hook and a rear grip surface of the locking element is effected at orthogonal to the formwork facing forces. In this regard, the one sub-segment according to a development of the invention in particular one

Supporting surface, which is at least partially positively brought to bear on a support surface of the other subsegment, wherein the support surface has an undercut, which is engaged behind by the support surface.

angeordnete Sperrnut aufweisen, in der ein Innenwandabschnitt des jeweilig anderen Teilsegments angeordnet bzw. festgelegt ist. Have arranged locking groove, in which an inner wall portion of the respective other subsegment is arranged or fixed.
Zwecks einer möglichst einfachen Montage des Schalungselement ist die Hakverbindung insbesondere durch ein relatives Verschwenken der zu verbindenden Teüsegmente zueinander herstellbar. Dadurch können die For the simplest possible assembly of the formwork element the hook connection is in particular produced by a relative pivoting of the Teüsegmente to be joined to each other. This allows the
Teilsegmente als Hebel zum Schließen der Hakverbindung ausgenutzt werden, was insbesondere auch ein Schließen der Hakverbindung gegen eine Vorspannung der Teilsegmente ermöglicht. Sofern die Hakverbindung ein als Sperrelement und ein als Schnapphaken ausgebildetes Hakelemente aufweist, kann das in der Sperrnut geführte Sperrelement zudem einer scharnierartigen Führung der Teilsegmente beim Herstellen der Hakverbindung dienen. Partial segments are used as a lever for closing the Hakverbindung, which in particular allows a closing of the Hakverbindung against a bias of the sub-segments. If the hooked connection has a hooking element designed as a blocking element and a hooking hook, the blocking element guided in the blocking groove can also serve for a hinge-like guiding of the subsegments during the production of the hooked connection.
Die Hakverbindung erstreckt sich zwecks einer möglichst stabilen Verbindung der Teilsegmente vorzugsweise über einen Großteil der gesamten Länge, insbesondere die gesamte Länge, der Außen- und/oder Innenseite des Grundkörpers. For the purpose of the most stable possible connection of the sub-segments, the hook connection preferably extends over a large part of the entire length, in particular the entire length, of the outer and / or inner side of the main body.
Die Hohlprofilöffnungen des Schalungselements sind zwecks einer einfachen Reinigung hinsichtlich eines Eindringens von Verschmutzungen, wie etwa The hollow profile openings of the formwork element are for ease of cleaning in terms of penetration of contaminants, such as
Frischbeton, mittels Dichtelementen abgedichtet. Fresh concrete, sealed by means of sealing elements.
Hinsichtlich einer möglichst planen Schalhaut hat es sich überdies bewährt, dass die Teilsegmente bzw. der Grundkörper des Schalungselements an zumindest einer Stirnseite mit einem Richtprofil verbunden sind. With regard to a planning as possible facing, it has also proven that the sub-segments or the main body of the formwork element are connected at least one end face with a straightening profile.
Zwecks einer weiter optimierten Oberflächengüte der herzustellenden Betonbauteile und eines möglichst geringen Reinigungsaufwand des Schalungselements kann die als Schalhaut ausgebildete Außenseite des Schalelements bzw. der Teilsegmente zusätzlich eine Beschichtung aufweisen, die einem Anhaften von Frischbeton bzw. von abgebundenem Beton entgegenwirkt. Diese Beschichtung kann insbesondere eine Kunststoffbeschichtung bzw. eine Pulverlackbeschichtung sein. For the purpose of a further optimized surface quality of the concrete components to be produced and the lowest possible cleaning of the formwork element, the outside of the formwork element or the subsegments designed as formwork skin can additionally have a coating which counteracts the adhesion of fresh concrete or hardened concrete. This coating may in particular be a plastic coating or a powder coating.
Das Schalungselement weist erfindungsgemäß eine Breite von unter 1000 mm, eine Dicke von 20 bis 80 mm und eine Länge von weniger als 4000mm, vorzugsweise von weniger als 3600 mm, auf. Zwecks einer besonders einfachen und sicheren According to the invention, the formwork element has a width of less than 1000 mm, a thickness of 20 to 80 mm and a length of less than 4000 mm, preferably less than 3600 mm. For the purpose of a particularly simple and safe
Handhabbarkeit in Bezug auf das Gewicht und die Außenmaße des Handling in relation to the weight and the external dimensions of the
Schalungselements hat es sich dabei in der Praxis als besonders vorteilhaft erwiesen, wenn das Schalungselement nicht breiter als 600 mm ist. Die Rippen bzw. Seitenwände des Hohlprofils (Teilsegment) sind zwischen der Innenseite und der Außenseite des Schalelements geneigt und dies in einem Winkel von kleiner 90°. Die Querkraftaufnahme lässt sich noch dadurch weiter verbessern, wenn die Winkel zwischen 30° und 70° ausgebildet sind. Besonders bevorzugt ist dabei ein Winkel der Rippen bzw. Seitenwände von etwa 45° zur Außenseite, weil sich dadurch das Hohiprofil einerseits sehr kostengünstig fertigen lässt und andererseits derartige Zwischensegmente oder Randsegmente die auf sie wirkenden Querkräfte verformungsfrei aufnehmen können. Shuttering it has proven to be particularly advantageous in practice, when the formwork element is not wider than 600 mm. The ribs or side walls of the hollow profile (sub-segment) are inclined between the inside and the outside of the shell element and this at an angle of less than 90 °. The transverse force absorption can still be further improved if the angles are formed between 30 ° and 70 °. In this case, an angle of the ribs or side walls of approximately 45 ° to the outside is particularly preferred, because thereby the Hohiprofil on the one hand very cost-effectively finished and on the other hand such intermediate segments or edge segments can absorb the transverse forces acting on them deformation-free.
