Definitions

  • the invention relates to a frame formwork element for forming a solidifiable building material, with a frame and a multi-layer formwork facing attached to the frame according to the preamble of claim 1.
  • the invention also relates to a formwork system according to claim 12.
  • Frame formwork elements are used as parts of formwork systems, in particular for the production of concrete components.
  • the frame formwork elements are arranged in such a way that they form a mold into which a solidifiable building material, mostly a liquid concrete, is introduced for the production of a concrete component, for example a wall element. After the concrete has solidified, the frame formwork elements are usually removed.
  • the frame formwork elements have a frame to which the formwork skin is attached.
  • the frames of the frame formwork elements should be stable in order to be able to transfer the loads that occur when the formwork system is filled with solidifiable concrete.
  • the frame should be sufficiently rigid to ensure high dimensional accuracy and avoid undesirable deformation.
  • the structure of a surface of the concrete component facing the formwork skin is determined by the formwork skin attached to the frame.
  • a front side of the formlining faces the concrete to be filled, that is, the front side of the formwork skin forms the surface in contact with the concrete, while the rear side of the formwork skin is attached to the frame.
  • Damage to the front side of the formwork facing the concrete which can result, for example, from the transport or handling of the panel formwork element in construction site operation, is reflected accordingly on the visible surface of the concrete component to be produced from the concrete. Damage to the formlining must therefore be repaired, which is done, for example, by filling out minor damage or by implementing repair sheets in the case of larger-area damage.
  • the formwork skin is structured in its surface as a result, which is undesirable when producing concrete components.
  • Frame formwork elements made of wood are known from the prior art. These have the disadvantage that they swell due to penetrating moisture. In the event of heavy use, the protective impregnation layer is destroyed and the surface frays. Furthermore, nails that are hammered into the formwork element during use lead to damage to the veneer layer or the protective impregnation layer, so that water can penetrate at these points.
  • Frame formwork elements made of plastic are also known from the prior art. These do not show any swelling behavior due to penetrating water when they are damaged, but like wooden panels they have to be repaired in a complex and manual manner if they have been damaged during use, in particular on the surface of the formwork facing the concrete.
  • a frame formwork element of the generic type is known from DE 101 14 161 A1.
  • the generic frame formwork element has a frame and a multilayer formwork skin attached to the frame. It is provided that the surface of the formwork facing or touching the concrete is formed by a formwork foil.
  • DE 101 14 161 A1 is based on the idea of avoiding time-consuming repair and improvement work on the formwork facing for reuse by replacing a scratched or otherwise damaged surface of the formwork facing with a new formwork film.
  • DE 101 14 161 A1 provides for the surface of the formwork facing facing the concrete to be coated with a new formwork sheet in order to reuse the frame formwork element.
  • the framed formwork element known from DE 101 14 161 A1 is intended to have a formwork skin with a formwork film, which can be detached from the carrier system and exchanged without being destroyed.
  • the formwork foil is supposed to form the actual contact surface with the concrete and is responsible for the surface structure and the surface quality of the concrete.
  • the object of the present invention is therefore to improve the frame formwork elements known from the prior art for forming a solidifying building material, in particular to enable a repair if the surface of the formwork facing the building material is damaged, and to increase the static load-bearing capacity of the frame formwork element as much as possible to enhance.
  • Another object of the present invention is to improve the formwork systems known from the prior art, in particular to simplify their repair and to improve the static load-bearing capacity as far as possible.
  • the frame formwork element according to the invention for forming a solidifying building material has a frame and a multi-layer formwork skin attached to the frame.
  • the formwork skin has a support plate and a rigid wear plate.
  • the support plate is attached to the frame and the wear plate is releasably attached to the support plate.

  • the rigid wear plate thus forms a wear layer that can be changed if necessary.
  • the wear plate the front of which is facing the building material to be consolidated and thus the structure of the surface, d. H. the visible surface, the building material, especially concrete, can be replaced quickly and easily if the wear plate is damaged. This measure can be carried out in particular if the front side of the wear plate facing the building material should be damaged. It is easier to replace the rigid wear plate than to coat the formlining with a new formwork foil. Furthermore, a rigid wear plate is more robust than a shuttering foil, which is particularly advantageous in daily use on the construction site.
  • the feature that the wear plate is releasably attached to the support plate preferably also includes a conditionally releasable connection, i.e. H. if only the auxiliary joining parts have to be destroyed in order to detach the wear plate from the support plate.
  • the frame of the frame formwork element is preferably made of metal, in particular iron or steel.
  • the invention provides for the support plate of the formwork facing to be attached to the frame in a tensile and shear-proof manner in such a way that the support plate statically supports the frame improves the static load-bearing capacity of the entire panel formwork element.

  • the support plate is firmly connected to the frame or firmly installed in the frame, so that the support plate statically supports the frame.

Description

Rahmenschalunqselement und Schalunqssvstem Framed formwork element and formwork system
Die Erfindung betrifft ein Rahmenschalungselement zum Schalen eines verfestig baren Baustoffs, mit einem Rahmen und einer am Rahmen angebrachten mehrschichtigen Schalhaut nach dem Oberbegriff von Anspruch 1 . The invention relates to a frame formwork element for forming a solidifiable building material, with a frame and a multi-layer formwork facing attached to the frame according to the preamble of claim 1.
Die Erfindung betrifft ferner ein Schalungssystem nach Anspruch 12. The invention also relates to a formwork system according to claim 12.
Rahmenschalungselemente werden als Teile von Schalungssystemen insbesondere zur Herstellung von Betonbauteilen verwendet. Die Rahmenschalungselemente werden dabei derart angeordnet, dass diese eine Gussform bilden, in die ein verfestigbarer Baustoff, zumeist ein flüssiger Beton, zur Herstellung eines Betonbauteils, beispielsweise eines Wandelements, eingebracht wird. Nach dem Verfestigen des Betons werden die Rahmenschalungselemente im Regelfall entfernt. Frame formwork elements are used as parts of formwork systems, in particular for the production of concrete components. The frame formwork elements are arranged in such a way that they form a mold into which a solidifiable building material, mostly a liquid concrete, is introduced for the production of a concrete component, for example a wall element. After the concrete has solidified, the frame formwork elements are usually removed.
Die Rahmenschalungselemente weisen einen Rahmen auf, an dem die Schalhaut angebracht ist. The frame formwork elements have a frame to which the formwork skin is attached.
Die Rahmen der Rahmenschalungselemente sollen einerseits standsicher sein, um die beim Verfüllen des Schalungssystems mit verfestigbarem Beton auftretenden Lasten abtragen zu können. Andererseits soll der Rahmen ausreichend steif sind, um eine hohe Maßgenauigkeit zu gewährleisten und unerwünschte Verformung zu vermeiden. On the one hand, the frames of the frame formwork elements should be stable in order to be able to transfer the loads that occur when the formwork system is filled with solidifiable concrete. On the other hand, the frame should be sufficiently rigid to ensure high dimensional accuracy and avoid undesirable deformation.
Die Struktur einer der Schalhaut zugewandten Oberfläche des Betonbauteils, nachfolgend auch als "Sichtfläche" bezeichnet, wird durch die am Rahmen angebrachte Schalhaut bestimmt. Eine Vorderseite der Schalhaut ist dabei dem einzufüllenden Beton zugewandt, das heißt die Vorderseite der Schalhaut bildet die Beton berührende Oberfläche aus, während die Rückseite der Schalhaut an dem Rahmen angebracht ist. The structure of a surface of the concrete component facing the formwork skin, hereinafter also referred to as the "visible surface", is determined by the formwork skin attached to the frame. A front side of the formlining faces the concrete to be filled, that is, the front side of the formwork skin forms the surface in contact with the concrete, while the rear side of the formwork skin is attached to the frame.
Beschädigungen an der dem Beton zugewandten Vorderseite der Schalhaut, die sich beispielsweise durch den Transport oder das Handling des Rahmenschalungselements im Baustellenbetrieb ergeben können, bilden sich entsprechend an der Sichtfläche des aus dem Beton herzustellenden Betonbauteils ab. Beschädigungen an der Schalhaut müssen daher repariert werden, was beispielsweise durch Ausspachteln kleinerer Beschädigungen oder durch das Implementieren von Reparaturblättchen bei grö- ßerflächigen Beschädigungen erfolgt. Die Schalhaut wird hierdurch jedoch in ihrer Oberfläche strukturiert, was beim Herstellen von Betonbauteilen unerwünscht ist. Damage to the front side of the formwork facing the concrete, which can result, for example, from the transport or handling of the panel formwork element in construction site operation, is reflected accordingly on the visible surface of the concrete component to be produced from the concrete. Damage to the formlining must therefore be repaired, which is done, for example, by filling out minor damage or by implementing repair sheets in the case of larger-area damage. However, the formwork skin is structured in its surface as a result, which is undesirable when producing concrete components.
Aus dem Stand der Technik sind Rahmenschalungselemente aus Holz bekannt. Diese weisen den Nachteil auf, dass sie durch eindringende Feuchtigkeit aufquellen. Bei starker Beanspruchung wird die schützende Imprägnierschicht zerstört und die Oberfläche fasert auf. Des Weiteren führen Nägel, die bei Gebrauch in das Schalungselement eingeschlagen werden, zu Beschädigungen der Furnierschicht oder der schützenden Imprägnierschicht, so dass an diesen Stellen Wasser eindringen kann. Aus dem Stand der Technik sind auch Rahmenschalungselemente aus Kunststoff bekannt. Diese weisen zwar bei Beschädigungen kein Quellverhalten durch eindringendes Wasser auf, müssen aber ebenso wie Holzplatten aufwändig und manuell repariert werden, wenn diese im Gebrauch, insbesondere an der dem Beton zugewandten Oberfläche der Schalhaut, beschädigt wurden. Frame formwork elements made of wood are known from the prior art. These have the disadvantage that they swell due to penetrating moisture. In the event of heavy use, the protective impregnation layer is destroyed and the surface frays. Furthermore, nails that are hammered into the formwork element during use lead to damage to the veneer layer or the protective impregnation layer, so that water can penetrate at these points. Frame formwork elements made of plastic are also known from the prior art. These do not show any swelling behavior due to penetrating water when they are damaged, but like wooden panels they have to be repaired in a complex and manual manner if they have been damaged during use, in particular on the surface of the formwork facing the concrete.
Ein gattungsgemäßes Rahmenschalungselement ist aus der DE 101 14 161 A1 bekannt. Das gattungsgemäße Rahmenschalungselement weist einen Rahmen und eine am Rahmen angebrachte mehrschichtige Schalhaut auf. Dabei ist vorgesehen, dass die den Beton berührende bzw. zugewandte Oberfläche der Schalhaut, durch eine Schalfolie gebildet wird. Der DE 101 14 161 A1 liegt dabei der Gedanke zugrunde, zeitintensive Reparatur- und Ausbesserungsarbeiten der Schalhaut zur Wiederverwendung dadurch zu vermeiden, dass eine verkratzte oder anderweitig beschädigte Oberfläche der Schalhaut durch eine neue Schalfolie ersetzt wird. Es ist gemäß der DE 101 14 161 A1 vorgesehen, zur Wiederverwendung des Rahmenschalungselements die dem Beton zugewandte Oberfläche der Schalhaut mit einer neuen Schalfolie zu beschichten. Das aus der DE 101 14 161 A1 bekannte Rahmenschalungselement soll eine Schalhaut mit einer Schalfolie aufweisen, welche zerstörungsfrei vom Trägersystem gelöst und ausgetauscht werden kann. Die Schalfolie soll dabei die eigentliche Kontaktfläche zum Beton bilden und ist für die Oberflächenstrukturierung sowie die Oberflächenqualität des Betons verantwortlich. A frame formwork element of the generic type is known from DE 101 14 161 A1. The generic frame formwork element has a frame and a multilayer formwork skin attached to the frame. It is provided that the surface of the formwork facing or touching the concrete is formed by a formwork foil. DE 101 14 161 A1 is based on the idea of avoiding time-consuming repair and improvement work on the formwork facing for reuse by replacing a scratched or otherwise damaged surface of the formwork facing with a new formwork film. DE 101 14 161 A1 provides for the surface of the formwork facing facing the concrete to be coated with a new formwork sheet in order to reuse the frame formwork element. The framed formwork element known from DE 101 14 161 A1 is intended to have a formwork skin with a formwork film, which can be detached from the carrier system and exchanged without being destroyed. The formwork foil is supposed to form the actual contact surface with the concrete and is responsible for the surface structure and the surface quality of the concrete.
Die Verwendung einer Schalfolie, die nach Verschleiß von der Schalhaut gelöst und durch eine neue Schalfolie ersetzt wird, ist allerdings aufgrund des hierfür notwendigen Beschichtungsvorgangs nicht optimal. The use of a shuttering foil, which is detached from the formlining after wear and tear and replaced by a new shuttering foil, is, however, not optimal due to the coating process required for this.
Von Nachteil bei der Verwendung von Schalfolien ist zudem, dass sich die Schalfolie werfen kann und dadurch unbrauchbar wird. Another disadvantage when using formwork foils is that the formwork foil can throw itself and become unusable as a result.
Bei Rahmenschalungselementen ist es allgemein wünschenswert, wenn diese eine möglichst hohe statische Belastbarkeit aufweisen, auch diesbezüglich gilt es, die aus dem Stand der Technik bekannten Rahmenschalungselemente zu verbessern. In the case of framed formwork elements, it is generally desirable if they have the highest possible static load-bearing capacity; in this respect, too, it is important to improve the framed formwork elements known from the prior art.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, die aus dem Stand der Technik bekannten Rahmenschalungselemente zum Schalen eines verfestig baren Baustoffs zu verbessern, insbesondere bei einer Beschädigung der dem Baustoff zugewandten Oberfläche der Schalhaut eine Reparatur zu ermöglichen, und die statische Tragfähigkeit des Rahmenschalungselements möglichst zu verbessern. The object of the present invention is therefore to improve the frame formwork elements known from the prior art for forming a solidifying building material, in particular to enable a repair if the surface of the formwork facing the building material is damaged, and to increase the static load-bearing capacity of the frame formwork element as much as possible to enhance.
Der vorliegenden Erfindung liegt ferner die Aufgabe zugrunde, die aus dem Stand der Technik bekannten Schalungssysteme zu verbessern, insbesondere deren Reparatur zu vereinfachen und die statische Trägfähigkeit möglichst zu verbessern. Another object of the present invention is to improve the formwork systems known from the prior art, in particular to simplify their repair and to improve the static load-bearing capacity as far as possible.
Diese Aufgabe wird hinsichtlich des Rahmenschalungselements durch die Merkmale des Anspruchs 1 gelöst. Diese Aufgabe wird hinsichtlich des Schalungssystems durch die Merkmale des Anspruchs 12 gelöst. This object is achieved with regard to the panel formwork element by the features of claim 1. With regard to the formwork system, this object is achieved by the features of claim 12.
Insofern im Rahmen der Beschreibung der Erfindung nachfolgend anstelle des allgemeinen Begriffs "Baustoff der spezifische Begriff "Beton" verwendet wird, ist dies auch als Offenbarung für den allgemeinen Begriff "Baustoff zu verstehen. Insofar as the specific term “concrete” is used below in the context of the description of the invention instead of the general term “building material”, this is also to be understood as a disclosure for the general term “building material”.
Das erfindungsgemäße Rahmenschalungselement zum Schalen eines verfestig baren Baustoffs weist einen Rahmen und eine am Rahmen angebrachte mehrschichtige Schalhaut auf. Die Schalhaut weist erfindungsgemäß eine Tragplatte und eine starre Verschleißplatte auf. Die Tragplatte ist an dem Rahmen befestigt und die Verschleißplatte ist lösbar an der Tragplatte festgelegt. Eine von der Tragplatte abgewandte Vorderseite der Verschleißplatte ist als den Baustoff berührende Oberfläche ausgebildet. Die Tragplatte ist zug- und schubfest an dem Rahmen befestigt derart, dass die Tragplatte den Rahmen statisch unterstützt, wobei die Tragplatte unlösbar oder bedingt lösbar mit dem Rahmen verbunden ist. The frame formwork element according to the invention for forming a solidifying building material has a frame and a multi-layer formwork skin attached to the frame. According to the invention, the formwork skin has a support plate and a rigid wear plate. The support plate is attached to the frame and the wear plate is releasably attached to the support plate. A front side of the wear plate facing away from the support plate is designed as a surface in contact with the building material. The support plate is attached to the frame in a tensile and shear-proof manner in such a way that the support plate statically supports the frame, the support plate being permanently or partially releasably connected to the frame.
Dadurch, dass die Schalhaut erfindungsgemäß eine Tragplatte und eine starre Verschleißplatte aufweist, ergeben sich mehrere Vorteile. Zum einen hat der Erfinder erkannt, dass sich eine starre Verschleißplatte besonders einfach und vorteilhaft von der Tragplatte lösen lässt. The fact that the formlining according to the invention has a support plate and a rigid wear plate results in several advantages. On the one hand, the inventor has recognized that a rigid wear plate can be detached from the support plate in a particularly simple and advantageous manner.
Die starre Verschleißplatte bildet somit einen Verschleißbelag aus, der bei Bedarf gewechselt werden kann. The rigid wear plate thus forms a wear layer that can be changed if necessary.
Die Verschleißplatte, deren Vorderseite dem zu verfestigenden Baustoff zugewandt ist und die somit die Struktur der Oberfläche, d. h. der Sichtfläche, des Baustoffs, insbesondere eines Betons beeinflusst, kann schnell und einfach ausgetauscht werden, wenn die Verschleißplatte beschädigt ist. Diese Maßnahme kann insbesondere dann durchgeführt werden, wenn die dem Baustoff zugewandte Vorderseite der Verschleißplatte beschädigt sein sollte. Ein Austausch der starren Verschleißplatte ist einfacher möglich als die Schalhaut mit einer neuen Schalfolie zu beschichten. Ferner ist eine starre Verschleißplatte robuster als eine Schalfolie, was insbesondere im täglichen Einsatz auf der Baustelle von Vorteil ist. The wear plate, the front of which is facing the building material to be consolidated and thus the structure of the surface, d. H. the visible surface, the building material, especially concrete, can be replaced quickly and easily if the wear plate is damaged. This measure can be carried out in particular if the front side of the wear plate facing the building material should be damaged. It is easier to replace the rigid wear plate than to coat the formlining with a new formwork foil. Furthermore, a rigid wear plate is more robust than a shuttering foil, which is particularly advantageous in daily use on the construction site.
Das Merkmal, dass die Verschleißplatte lösbar an der Tragplatte festgelegt ist, umfasst vorzugsweise auch eine bedingt lösbare Verbindung, d. h. wenn nur die Hilfsfügeteile zerstört werden müssen, um die Verschleißplatte von der Tragplatte zu lösen. The feature that the wear plate is releasably attached to the support plate preferably also includes a conditionally releasable connection, i.e. H. if only the auxiliary joining parts have to be destroyed in order to detach the wear plate from the support plate.
Der Rahmen des Rahmenschalungselements ist vorzugsweise aus Metall, insbesondere aus Eisen bzw. Stahl ausgebildet. The frame of the frame formwork element is preferably made of metal, in particular iron or steel.
Dadurch, dass erfindungsgemäß vorgesehen ist, die Tragplatte der Schalhaut zug- und schubfest an dem Rahmen zu befestigen, derart, dass die Tragplatte den Rahmen statisch unterstützt, wird die statische Belastungsfähigkeit des gesamten Rahmenschalungselementes verbessert. Eine unlösbare Verbindung der Tragplatte mit dem Rahmen hat sich als besonders geeignet herausgestellt. Die Tragplatte kann somit den Rahmen in besonders vorteilhafter Weise statisch unterstützen. Auch eine bedingte Lösbarkeit der Tragplatte von dem Rahmen kann sich hierfür eignen. Eine bedingte Lösbarkeit liegt beispielsweise dann vor, wenn nur die Hilfsfügeteile zerstört werden müssen aber nicht die Tragplatte bzw. der Rahmen, um die Teile voneinander zu lösen. Hierunter fällt beispielsweise das Abschlagen der Niete bei einer Nietverbindung. The fact that the invention provides for the support plate of the formwork facing to be attached to the frame in a tensile and shear-proof manner in such a way that the support plate statically supports the frame improves the static load-bearing capacity of the entire panel formwork element. A permanent connection between the support plate and the frame has proven to be particularly suitable. The support plate can thus statically support the frame in a particularly advantageous manner. Conditional releasability of the support plate from the frame can also be suitable for this. Conditional releasability exists, for example, when only the auxiliary joining parts have to be destroyed but not the support plate or the frame in order to release the parts from one another. This includes, for example, knocking off the rivets in a riveted connection.
Vorzugsweise ist die Tragplatte fest mit dem Rahmen verbunden bzw. fest in den Rahmen eingebaut, so dass die Tragplatte den Rahmen statisch unterstützt. In die bisherigen Berechnungen zur statischen Tragfähigkeit eines Rahmenschalungselementes wurde die Schalhaut nicht einbezogen. Dadurch, dass die Schalhaut eine Tragplatte und eine starre Verschleißplatte aufweist, ist es nunmehr möglich, die Tragplatte dauerhaft, zug- und schubfest an dem Rahmen zu befestigen, so dass die Tragplatte den Rahmen statisch unterstützt und somit in die Berechnung zur statischen Tragfähigkeit einbezogen werden kann. Preferably, the support plate is firmly connected to the frame or firmly installed in the frame, so that the support plate statically supports the frame. The formwork facing was not included in the previous calculations for the static load-bearing capacity of a panel formwork element. Because the formlining has a support plate and a rigid wear plate, it is now possible to attach the support plate to the frame in a permanent, tensile and shear-proof manner, so that the support plate statically supports the frame and is thus included in the calculation of the static load-bearing capacity can.
Vorzugsweise ist vorgesehen, dass die Tragplatte derart ausgelegt ist, dass diese über die kalkulierte Lebensdauer des Rahmenschalungselements mit dem Rahmen verbunden bleibt bzw. Bestandteil des Rahmenschalungselementes bleibt. It is preferably provided that the support plate is designed in such a way that it remains connected to the frame or remains part of the frame formwork element over the calculated service life of the frame formwork element.
Es kann im Rahmen der Erfindung vorgesehen sein, dass die Tragplatte selbst mehrschichtig aufgebaut ist, wobei die Schichten der T ragplatte vorzugsweise miteinander verleimt, verklebt oder anderweitig stoffschlüssig und/oder kraftschlüssig und/oder formschlüssig miteinander verbunden sind. It can be provided within the scope of the invention that the support plate itself has a multi-layer structure, the layers of the support plate preferably being glued, glued or otherwise cohesively and / or non-positively and / or positively connected to one another.
In besonderer Weise eignet es sich jedoch, wenn die Tragplatte einteilig ausgebildet ist. However, it is particularly suitable if the support plate is made in one piece.
Ferner eignet es sich in besonderer Weise, wenn auch die starre Verschleißplatte einteilig ausgebildet ist. Furthermore, it is particularly suitable if the rigid wear plate is also made in one piece.
Die Tragplatte ist vorzugsweise derart ausgelegt, dass diese die Durchbiegung der starren Verschleißplatte verhindert. Die Trag platte ist vorzugsweise starr ausgebildet. Die Trag platte ist vorzugsweise witterungsbeständig ausgebildet. Des Weiteren ist die Tragplatte vorzugsweise nagelbar ausgebildet. Vorzugsweise weist die Tragplatte einen hohen Auszugswiderstand für die Nägel auf. Die Tragplatte ist vorzugsweise derart ausgebildet und/oder behandelt, dass diese resistent ist gegenüber den üblichen Schalmitteln. The support plate is preferably designed in such a way that it prevents the rigid wear plate from bending. The support plate is preferably rigid. The support plate is preferably weatherproof. Furthermore, the support plate is preferably designed to be nailable. The support plate preferably has a high pull-out resistance for the nails. The support plate is preferably designed and / or treated in such a way that it is resistant to the usual formwork elements.
Erfindungsgemäß kann vorgesehen sein, dass die Tragplatte 30 % bis 80 %, vorzugsweise 40 % bis 80 %, weiter bevorzugt 40 % bis 70 %, besonders bevorzugt 50 % bis 70 % und ganz besonders bevorzugt 50 % bis 60 %, der Stärke der Schalhaut aufweist. Die vorgenannten Werte haben sich als besonders geeignet herausgestellt, insbesondere damit die Tragplatte den Rahmen statisch unterstützt und eine Durchbiegung der Verschleißplatte zuverlässig verhindert wird. According to the invention, it can be provided that the support plate is 30% to 80%, preferably 40% to 80%, more preferably 40% to 70%, particularly preferably 50% to 70% and very particularly preferably 50% to 60%, of the thickness of the formlining having. The aforementioned values have proven to be particularly suitable, in particular so that the support plate statically supports the frame and a deflection of the wear plate is reliably prevented.
Von Vorteil ist es, wenn die Tragplatte eine Stärke von 6 bis 14 mm, vorzugsweise 7 bis 13 mm, weiter bevorzugt 8 bis 12 mm, besonders bevorzugt 8 bis 11 mm und ganz besonders bevorzugt 8 bis 10 mm, insbesondere 9 mm, aufweist. It is advantageous if the support plate has a thickness of 6 to 14 mm, preferably 7 to 13 mm, more preferably 8 to 12 mm, particularly preferably 8 to 11 mm and very particularly preferably 8 to 10 mm, in particular 9 mm.
Die vorgenannten Werte haben sich zur Ausbildung der Tragplatte als besonders geeignet herausgestellt. The aforementioned values have proven to be particularly suitable for designing the support plate.
Die vorgenannten Werte eignen sich insbesondere in Verbindung mit den vorgenannten %-Werten, die die Tragplatte bezüglich der Stärke der Schalhaut aufweisen kann. The aforementioned values are particularly suitable in connection with the aforementioned% values that the support plate can have with regard to the thickness of the formwork facing.
Erfindungsgemäß kann ferner vorgesehen sein, dass die Tragplatte kraftschlüssig und/oder stoffschlüssig und/oder formschlüssig mit dem Rahmen verbunden ist. According to the invention it can further be provided that the support plate is connected to the frame in a force-locking and / or material-locking and / or form-locking manner.
Erfindungsgemäß kann vorgesehen sein, dass die Tragplatte mit dem Rahmen verklebt und/oder verschweißt und/oder verlötet und/oder vernietet und/oder verschraubt und/oder vernagelt ist. Ferner kann der Rahmen auch Vorsprünge, beispielsweise einen umlaufenden vorspringenden Rand, aufweisen, so dass die Tragplatte formschlüssig in den umlaufenden Rand des Rahmens einlegbar ist. Der umlaufende Rand kann dabei auch Aussparungen bzw. Unterbrechungen aufweisen. According to the invention it can be provided that the support plate is glued and / or welded and / or soldered and / or riveted and / or screwed and / or nailed to the frame. Furthermore, the frame can also have projections, for example a circumferential protruding edge, so that the support plate can be inserted into the circumferential edge of the frame in a form-fitting manner. The circumferential edge can also have recesses or interruptions.
Es hat sich als besonders geeignet herausgestellt, die Tragplatte mit dem Rahmen durch Nieten zu verbinden, d. h. die Tragplatte an den Rahmen anzunieten. It has been found to be particularly suitable to connect the support plate to the frame by riveting, i. E. H. rivet the support plate to the frame.
Von Vorteil ist es, wenn die Tragplatte als Metallplatte, als Kunststoffplatte, als Platte aus einem Faserverbundwerkstoff, als Holzplatte oder als Verbundplatte ausgebildet ist. It is advantageous if the support plate is designed as a metal plate, a plastic plate, a plate made of a fiber composite material, a wooden plate or a composite plate.
Vorgesehen sein kann auch eine Herstellung der Tragplatte aus einer Kunststoff-Verbund-Konstruktion, z. B. eine Sandwichplatte bestehend aus Polypropylen und Aluminium bzw. Glasfaser vorzugsweise unter Verzicht auf Holz oder Holzteile. Eine derartige Tragplatte ist dabei nagelbar und reparaturfähig wie eine Holzplatte. A production of the support plate from a plastic composite construction, e.g. B. a sandwich panel consisting of polypropylene and aluminum or fiberglass, preferably without using wood or wooden parts. Such a support plate can be nailed and repaired like a wooden plate.
Es kann insbesondere vorgesehen sein, dass die Tragplatte als Kunststoffplatte aus Polyethylen oder Polypropylen ausgebildet ist. In particular, it can be provided that the support plate is designed as a plastic plate made of polyethylene or polypropylene.
Es kann im Rahmen der Erfindung auch vorgesehen sein, dass in die Tragplatte ein Streckmetall eingebracht, vorzugsweise eingeschweißt, ist. Das Einbringen bzw. Einschweißen eines Streckmetalls kann dabei die Tragfähigkeit der Tragplatte weiter erhöhen, wodurch der Rahmen statisch weiter unterstützt wird. Die starre Verschleißplatte kann grundsätzlich ebenfalls als Metallplatte, als Kunststoffplatte, als Platte aus einem Faserverbundwerkstoff, als Holzplatte oder als Verbundplatte ausgebildet sein. Von Vorteil kann es insbesondere sein, die starre Verschleißplatte aus Holz oder Kunststoff auszubilden. It can also be provided within the scope of the invention that an expanded metal is introduced, preferably welded, into the support plate. The introduction or welding in of an expanded metal can further increase the load-bearing capacity of the support plate, as a result of which the frame is further supported statically. The rigid wear plate can in principle also be designed as a metal plate, a plastic plate, a plate made of a fiber composite material, a wooden plate or a composite plate. It can be particularly advantageous to make the rigid wear plate out of wood or plastic.
Die Tragplatte soll vorzugsweise derart ausgebildet sein, dass diese nagelbar ist mit geringen Ausrissbeschädigungen, insbesondere auf der von der starren Verschleißplatte abgewandten Rückseite der Tragplatte. The support plate should preferably be designed in such a way that it can be nailed with little tear damage, in particular on the back of the support plate facing away from the rigid wear plate.
Erfindungsgemäß kann ferner vorgesehen sein, dass die Tragplatte Öffnungen zum Lösen und/oder Bohrungen zum Befestigen der Verschleißplatte aufweist. According to the invention it can further be provided that the support plate has openings for loosening and / or bores for fastening the wear plate.
Es hat sich als vorteilhaft herausgestellt, wenn die Tragplatte Öffnungen zum Lösen der Verschleißplatte aufweist. Die Öffnungen können dabei als Wartungsöffnungen ausgebildet sein, durch die die starre Verschleißplatte vorzugsweise ausgepresst werden kann. Von Vorteil ist es ferner, wenn die Tragplatte Bohrungen zum Befestigen der Verschleißplatte aufweist. Die Bohrungen können dabei beispielsweise zum Verschrauben und/oder zum Durchnieten der Verschleißplatte vorgesehen sein. Vorzugsweise kann vorgesehen sein, dass die Verschleißplatte von der Rückseite der Tragplatte her verschraubt bzw. vernietet wird. It has been found to be advantageous if the support plate has openings for releasing the wear plate. The openings can be designed as maintenance openings through which the rigid wear plate can preferably be pressed out. It is also advantageous if the support plate has bores for fastening the wear plate. The bores can be provided, for example, for screwing and / or riveting through the wear plate. It can preferably be provided that the wear plate is screwed or riveted from the rear of the support plate.
Die von der Verschleißplatte abgewandte Rückseite der Tragplatte ist vorzugsweise derart gestaltet, dass diese mit einem Hochdruckreiniger leicht zu reinigen ist. The rear side of the support plate facing away from the wear plate is preferably designed in such a way that it can be easily cleaned with a high-pressure cleaner.
Des Weiteren kann es von Vorteil sein, wenn die Rückseite der Tragplatte lichtbeständig ausgeführt ist, d. h. sich unter der Einwirkung von Licht nicht verändert.

Furthermore, it can be advantageous if the rear side of the support plate is made light-resistant, i. E. H. does not change when exposed to light. The rear side of the plate is preferably designed in such a way that it fulfills at least a lightfastness of 5 (good), preferably a lightfastness of 6 (very good), according to DIN 53952, which is no longer valid.
Vorzugsweise ist die Tragplatte derart gestaltet, dass, wenn die Streben bzw. die Rahmenquerteile einen Abstand von 300 mm sowie einer Breite von 40 mm aufweisen, die Durchbiegung der Tragplatte maximal 1 ,5 mm beträgt. The support plate is preferably designed in such a way that if the struts or the frame transverse parts have a spacing of 300 mm and a width of 40 mm, the maximum deflection of the support plate is 1.5 mm.
In einer alternativen Ausgestaltung der Erfindung kann ferner vorgesehen sein, dass die Tragplatte in mehrere Tragplattensegmente unterteilt ist, die jeweils korrespondierende Segmente des Rahmens abdecken. In an alternative embodiment of the invention, it can also be provided that the support plate is subdivided into several support plate segments, each of which covers corresponding segments of the frame.
Die Unterteilung der Tragplatte in mehrere Tragplattensegmente, die jeweils korrespondierende Segmente des Rahmens abdecken, hat sich für spezifische Anwendungen als vorteilhaft heraussteilen. Die Tragplattensegmente können kostengünstig hergestellt und innerhalb der korrespondierenden Segmente zug- und schubfest festgelegt werden, so dass die Tragplattensegmente den Rahmen jeweils statisch unterstützen. Vorgesehen sein kann dabei auch, dass die Tragplattensegmente in die jeweils korrespondierenden Segmente des Rahmens formschlüssig eingesetzt werden. Der Formschluss kann vorzugsweise derart erfolgen, dass der Formschluss eine Bewegung der Tragplattensegmente innerhalb der Ebene der Tragplattensegmente verhindert. The subdivision of the support plate into several support plate segments, each covering corresponding segments of the frame, has proven to be advantageous for specific applications. The support plate segments can be manufactured inexpensively and fixed within the corresponding segments in a tensile and shear-proof manner, so that the support plate segments each statically support the frame. It can also be provided that the support plate segments in the respective Corresponding segments of the frame are used in a form-fitting manner.

It is advantageous if the frame has on its front side facing the support plate in the direction of the support plate protruding projections that delimit the segments, wherein the support plate segments are inserted into the segments that each of the support plate segments with an edge on at least one of the projections and at least one edge region adjoining the edge of the rear side of the support plate segment facing the frame bears against a surface of the front side of the frame adjoining the projection.
Die vorgenannte Ausgestaltung hat sich als besonders geeignet herausgestellt um die Tragplattensegmente formschlüssig festzulegen. Vorzugsweise ist dabei zusätzlich auch eine kraftschlüssige und/oder eine stoffschlüssige Verbindung vorgesehen. Es kann dabei vorgesehen sein, dass die Trag platte nseg- mente mit dem Rahmen alternativ oder ergänzend zu dem Formschluss verklebt und/oder verschweißt und/oder verlötet und/oder vernietet und/oder verschraubt und/oder vernagelt sind. The aforementioned configuration has been found to be particularly suitable for securing the support plate segments in a form-fitting manner. Preferably, a non-positive and / or material connection is also provided. It can be provided that the support plate segments are glued and / or welded and / or soldered and / or riveted and / or screwed and / or nailed to the frame as an alternative or in addition to the form fit.
Erfindungsgemäß kann ferner vorgesehen sein, dass die Verschleißplatte mit der Tragplatte vernagelt und/oder verschraubt und/oder vernietet und/oder lösbar verklebt ist. According to the invention it can further be provided that the wear plate is nailed and / or screwed and / or riveted and / or releasably glued to the support plate.
Die vorgenannten Möglichkeiten, die Verschleißplatte mit der Trag platte zu verbinden, haben sich als besonders geeignet herausgestellt. Vorzugsweise wird die Verschleißplatte von hinten, d. h. von der Rückseite her mit der Tragplatte vernagelt und/oder verschraubt und/oder vernietet. The aforementioned options to connect the wear plate with the support plate have been found to be particularly suitable. Preferably, the wear plate is attached from the rear, i. H. nailed and / or screwed and / or riveted to the support plate from the rear.
Erfindungsgemäß kann vorgesehen sein, dass die Verschleißplatte eine Stärke von 4 bis 11 mm, vorzugsweise 5 bis 10 mm, weiter bevorzugt 6 bis 10 mm, besonders bevorzugt 7 bis 10 mm, insbesondere 8 mm, aufweist. According to the invention it can be provided that the wear plate has a thickness of 4 to 11 mm, preferably 5 to 10 mm, more preferably 6 to 10 mm, particularly preferably 7 to 10 mm, in particular 8 mm.
Die vorgenannten Werte haben sich als besonders geeignet herausgestellt, so dass die Verschleißplatte starr ausgebildet und robust ist. Die vorgenannten Werte haben sich insbesondere auch in Verbindung mit den bezüglich der Tragplatte genannten Werten als besonders geeignet herausgestellt. The aforementioned values have proven to be particularly suitable, so that the wear plate is rigid and robust. The aforementioned values have also proven to be particularly suitable in connection with the values mentioned with regard to the support plate.
Es eignet sich in besonderer Weise zudem, wenn die Verschleißplatte wenigstens 20 % der Stärke der Schalhaut aufweist. Ferner eignet es sich in besonderer Weise, wenn die Verschleißplatte höchstens 50 % der Stärke der Schalhaut aufweist. Vorzugsweise weist die Tragplatte eine Stärke auf, die größer ist als die Stärke der Verschleißplatte. D. h. ausgehend von den vorzugsweise genannten Werten der Tragplatte, weist die Verschleißplatte vorzugsweise eine geringere Stärke auf, vorzugsweise derart, dass die Verschleißplatte eine Stärke von mindestens 4 mm aufweist, die Stärke der Verschleißplatte vorzugsweise jedoch mindestens 1 mm geringer ist als die Stärke der Tragplatte. Die Tragplatte ist vorzugsweise derart ausgebildet, dass diese die Tragfunktion in Bezug auf den Betondruck voll bzw. mindestens zu 70%, vorzugsweise mindestens zu 80 %, besonders bevorzugt mindestens zu 90 %, insbesondere mindestens zu 95 % übernimmt. Da bei dieser Ausgestaltung die Verschleißplatte nur in geringem Umfang bzw. keinen Betondruck aufnehmen muss, kann diese verglichen mit der Tragplatte dünner, vorzugsweise wesentlich dünner ausgeführt werden, wodurch die Kosten für die Verschleißplatte sinken und dadurch auch die Reparaturkosten gesenkt sind. It is also particularly suitable when the wear plate has at least 20% of the thickness of the formlining. Furthermore, it is particularly suitable if the wear plate has a maximum of 50% of the thickness of the formlining. The support plate preferably has a thickness which is greater than the thickness of the wear plate. I. E. Based on the preferred values of the support plate, the wear plate preferably has a smaller thickness, preferably such that the wear plate has a thickness of at least 4 mm, but the thickness of the wear plate is preferably at least 1 mm less than the thickness of the support plate. The support plate is preferably designed in such a way that it takes over the support function in relation to the concrete pressure fully or at least 70%, preferably at least 80%, particularly preferably at least 90%, in particular at least 95%. Since in this embodiment the wear plate has to absorb only a small amount or no concrete pressure, it can be made thinner, preferably significantly thinner, compared to the support plate, which reduces the costs for the wear plate and thereby also lowers the repair costs.
Die Erfindung betrifft auch ein Rahmenschalungssystem nach Anspruch 12, welches wenigstens zwei Rahmenschalungselemente und eine Mehrzahl von Ankerstäben aufweist, um die Rahmenschalungselemente auf Abstand zueinander zu verspannen. The invention also relates to a frame formwork system according to claim 12, which has at least two frame formwork elements and a plurality of tie rods in order to brace the frame formwork elements at a distance from one another.
Im Regelfall weisen die beiden Enden eines Ankerstabs ein Gewinde auf, auf welche Schraubenmuttern als Ankerfixierungen aufgeschraubt werden. Der mittlere Bereich eines Ankerstabs, an den während des Betonierens Beton angrenzen kann, weist vorzugsweise entweder eine glatte Oberfläche auf oder wird von einer Hülse bzw. einem Hüllrohr mit glatter Oberfläche umhüllt. Durch die Ankerfixierungen wird die wirksame Länge des Ankerstabs und damit die Stärke (Dicke) des zu betonierenden Betonbauteils, zum Beispiel einer Wand, festgelegt. As a rule, the two ends of an anchor rod have a thread onto which screw nuts are screwed as anchor fixings. The middle area of an anchor rod, which concrete can adjoin during concreting, preferably either has a smooth surface or is encased by a sleeve or a cladding tube with a smooth surface. The anchor fixings determine the effective length of the anchor rod and thus the strength (thickness) of the concrete component to be concreted, for example a wall.

Schalungssysteme und Rahmenschalungselemente sowie Verfahren zum Schalen eines verfestigbaren Baustoffs sind aus dem allgemeinen Stand der Technik hinlänglich bekannt, wozu beispielsweise auf die DE 102018 203 764 A1 verwiesen wird. Nachfolgend wird daher nur auf die für die Erfindung relevanten Merkmale näher eingegangen. Formwork systems and frame formwork elements as well as methods for forming a solidifiable building material are sufficiently known from the general prior art, for which reference is made, for example, to DE 102018 203 764 A1. In the following, therefore, only the features relevant to the invention will be discussed in more detail.
Die Figuren 1 und 2 zeigen ein Rahmenschalungselement 1 zum Schalen eines verfestigbaren Baustoffs. Bei dem Baustoff handelt es sich im Ausführungsbeispiel vorzugsweise um Beton. Die Erfindung ist hierauf jedoch nicht beschränkt. Das Ausführungsbeispiel ist derart zu verstehen, dass anstelle von Beton auch ein anderer verfestigbarer Baustoff zum Schalen verwendet werden kann. Figures 1 and 2 show a frame formwork element 1 for forming a solidifiable building material. In the exemplary embodiment, the building material is preferably concrete. However, the invention is not restricted to this. The exemplary embodiment is to be understood in such a way that instead of concrete, another solidifiable building material can also be used for the shuttering.
Das in Figur 1 und Figur 2 dargestellte Rahmenschalungselement 1 weist einen Rahmen 2 und eine am Rahmen 2 angebrachte mehrschichtige Schalhaut 3 auf. Der Rahmen 2 weist eine Mehrzahl an Rahmenlängsteilen 2a sowie eine Mehrzahl an Rahmenquerteilen 2b auf. Die äußeren Umrisse des Rahmens 2 werden dabei jeweils durch zwei Rahmenlängsteile 2a, nämlich ein linkes und ein rechtes Rahmenlängsteil 2a, und zwei Rahmenquerteile 2b, nämlich ein oberes und ein unteres Rahmenquerteil 2b, gebildet, zwischen denen jeweils weitere Rahmenlängsteile 2a bzw. Rahmenquerteile 2b ausgebildet sein können. Eine derartige Gestaltung des Rahmens 2 ist besonders vorteilhaft, die Erfindung und die Ausführungsbeispiele sind hierauf jedoch nicht beschränkt. The frame formwork element 1 shown in FIG. 1 and FIG. 2 has a frame 2 and a multilayer formwork skin 3 attached to the frame 2. The frame 2 has a plurality of longitudinal frame parts 2a and a plurality of transverse frame parts 2b. The outer outlines of the frame 2 are each formed by two frame longitudinal parts 2a, namely a left and a right frame longitudinal part 2a, and two frame transverse parts 2b, namely an upper and a lower frame transverse part 2b, between which further frame longitudinal parts 2a and frame transverse parts 2b are formed could be. Such a design of the frame 2 is particularly advantageous, but the invention and the exemplary embodiments are not limited thereto.
Wie aus den Figuren 3, 6 und 7 erkennbar ist, weist die Schalhaut 3 eine Tragplatte 4 und eine starre Verschleißplatte 5 auf. Die Tragplatte 4 ist an dem Rahmen 2 befestigt. Im Ausführungsbeispiel ist vorgesehen, dass die Tragplatte 4 unlösbar oder bedingt lösbar mit dem Rahmen 2 verbunden ist. Die von der Tragplatte 4 abgewandte Vorderseite 5a der Verschleißplatte 5 ist dabei als die den Baustoff berührende Oberfläche ausgebildet. Die Vorderseite 5a der Verschleißplatte 5 kann dabei gegebenenfalls derart gestaltet werden, dass sich eine gewünschte Struktur in der Sichtseite der zu erstellenden Betonkonstruktion, beispielsweise einer Wand, abbildet. As can be seen from FIGS. 3, 6 and 7, the formwork skin 3 has a support plate 4 and a rigid wear plate 5. The support plate 4 is attached to the frame 2. In the exemplary embodiment it is provided that the support plate 4 is connected to the frame 2 in a non-detachable or conditionally detachable manner. The front side 5a of the wear plate 5 facing away from the support plate 4 is designed as the surface in contact with the building material. The front side 5a of the wear plate 5 can optionally be designed in such a way that a desired structure is depicted in the visible side of the concrete structure to be created, for example a wall.
Im Ausführungsbeispiel ist vorgesehen, dass die Tragplatte 4 derart mit dem Rahmen 2 verbunden ist, dass die Tragplatte 4 über die vorgesehene Lebensdauer mit dem Rahmen 2 verbunden ist bzw. eine Einheit mit dem Rahmen 2 bildet und im Regelfall nicht gelöst werden muss. In the exemplary embodiment it is provided that the support plate 4 is connected to the frame 2 in such a way that the support plate 4 is connected to the frame 2 over the intended service life or forms a unit with the frame 2 and does not usually have to be detached.
Im Ausführungsbeispiel kann vorgesehen sein, dass die Tragplatte 4 kraftschlüssig und/oder stoffschlüssig und/oder formschlüssig mit dem Rahmen 2 verbunden ist. In the exemplary embodiment, it can be provided that the support plate 4 is connected to the frame 2 in a force-locking and / or material-locking and / or form-locking manner.
Die Tragplatte 4 ist an dem Rahmen 2 zug- und schubfest derart befestigt, dass die Tragplatte 4 den Rahmen 2 statisch unterstützt. Die Tragplatte 3 kann hierzu in nicht näher dargestellter Weise mit dem Rahmen 2 verklebt und/oder verschweißt und/oder verlötet und/oder vernietet und/oder verschraubt und/oder vernagelt sein. The support plate 4 is attached to the frame 2 in a tensile and shear-proof manner in such a way that the support plate 4 statically supports the frame 2. For this purpose, the support plate 3 can be glued and / or welded and / or soldered and / or riveted and / or screwed and / or nailed to the frame 2 in a manner not shown in detail.
Die Tragplatte 2 ist im Ausführungsbeispiel derart ausgelegt, dass diese den Betondruck vollständig bzw. zum größten Teil aufnimmt, so dass die Verschleißplatte 5 kostengünstig ausgeführt werden kann. In the exemplary embodiment, the support plate 2 is designed in such a way that it absorbs the concrete pressure completely or for the most part, so that the wear plate 5 can be made inexpensive.
Zur Ausbildung der Tragplatte 4 bieten sich verschiedene Werkstoffe an, wobei sich insbesondere Werkstoffe eignen, die den Betondruck aufnehmen können und dabei nur eine geringe Durchbiegung aufweisen. Ferner sollte der für die Tragplatte 4 verwendete Werkstoff witterungsbeständig sein. Various materials can be used to form the support plate 4, materials that can absorb the concrete pressure and thereby have only a slight deflection are particularly suitable. Furthermore, the material used for the support plate 4 should be weatherproof.
Im Ausführungsbeispiel kann vorgesehen sein, dass die Tragplatte 4 als Metallplatte, als Kunststoffplatte, als Platte aus einem Faserverbundwerkstoff, als Holzplatte oder als Verbundplatte ausgebildet ist. Die Tragplatte 4 kann insbesondere auch als geschäumte Kunststoffplatte ausgebildet sein. In the exemplary embodiment it can be provided that the support plate 4 is designed as a metal plate, as a plastic plate, as a plate made of a fiber composite material, as a wooden plate or as a composite plate. The support plate 4 can in particular also be designed as a foamed plastic plate.
Im Ausführungsbeispiel kann in nicht näher dargestellter Weise vorgesehen sein, dass in die Tragplatte 4 ein Streckmetall eingebracht, vorzugsweise eingeschweißt, ist, um die Tragfähigkeit der Tragplatte 4 zu steigern. In the exemplary embodiment, it can be provided, in a manner not shown in detail, that an expanded metal is introduced, preferably welded, into the support plate 4 in order to increase the load-bearing capacity of the support plate 4.
Die Verschleißplatte 5 ist im Ausführungsbeispiel vorzugsweise aus Kunststoff, Holz oder einem Verbundwerkstoff, insbesondere einem Faserverbundwerkstoff, ausgebildet. In the exemplary embodiment, the wear plate 5 is preferably made of plastic, wood or a composite material, in particular a fiber composite material.
Die Tragplatte 4 ist im Ausführungsbeispiel einstückig ausgebildet. Es ist jedoch auch möglich, die Tragplatte 4 mehrschichtig, zum Beispiel zwei- oder dreischichtig, auszubilden, das heißt, dass die Tragplatte 4 aus mehreren aufeinandergelegten Platten gebildet ist, die dann die Gesamtstärke der Tragplatte 4 bilden. Bei einer mehrschichtigen Ausbildung der Tragplatte 4 kann beispielsweise vorgesehen sein, dass die einzelnen Platten miteinander verleimt, verklebt oder vernietet sind. Im Ausführungsbeispiel ist vorgesehen, dass die Tragplatte 4 30 % bis 80 %, vorzugsweise 40 % bis 80 %, weiter bevorzugt 40 % bis 70 %, besonders bevorzugt 50 % bis 70 % und ganz besonders bevorzugt 50 % bis 60 %, der Stärke der Schalhaut 3 aufweist. The support plate 4 is formed in one piece in the exemplary embodiment. However, it is also possible to design the support plate 4 in multiple layers, for example two or three layers, that is to say that the support plate 4 is formed from several plates placed one on top of the other, which then form the total thickness of the support plate 4. In the case of a multi-layer design of the support plate 4, it can be provided, for example, that the individual plates are glued, glued or riveted to one another. In the exemplary embodiment it is provided that the support plate 4 is 30% to 80%, preferably 40% to 80%, more preferably 40% to 70%, particularly preferably 50% to 70% and very particularly preferably 50% to 60%, of the thickness of the Has formwork skin 3.
Im Ausführungsbeispiel ist ferner vorgesehen, dass die Tragplatte 4 eine Stärke von 6 bis 14 mm, vorzugsweise 7 bis 13 mm, weiter bevorzugt 8 bis 12 mm, besonders bevorzugt 8 bis 11 mm und ganz besonders bevorzugt 8 bis 10 mm, insbesondere 9 mm, aufweist.

Es hat sich als vorteilhaft herausgestellt, wenn die Tragplatte 4 eine Stärke aufweist, die größer ist als die Stärke der Verschleißplatte 5, so dass die Tragplatte 4 die Durchbiegung der starren Verschleißplatte 5 verhindert. Es ist jedoch beispielsweise auch möglich, dass die Tragplatte 4 und die Verschleißplatte 5 eine identische Stärke aufweisen, insbesondere derart, dass die Tragplatte 4 eine Stärke von 9 mm und auch die Verschleißplatte 5 eine Stärke von 9 mm aufweist. It has been found to be advantageous if the support plate 4 has a thickness which is greater than the thickness of the wear plate 5, so that the support plate 4 prevents the rigid wear plate 5 from bending. However, it is also possible, for example, that the support plate 4 and the wear plate 5 have an identical thickness, in particular such that the support plate 4 has a thickness of 9 mm and the wear plate 5 also has a thickness of 9 mm.
Die Verschleißplatte 5 weist im Ausführungsbeispiel eine Stärke von 4 bis 11 mm, vorzugsweise 5 bis 10 mm, weiter bevorzugt 6 bis 10 mm, besonders bevorzugt 7 bis 10 mm, insbesondere 8 mm, auf.

Im Ausführungsbeispiel ist vorgesehen, dass die Stärke der Schalhaut 3, die sich aus der Tragplatte 4 und der Verschleißplatte 5 zusammensetzt, zwischen 10 und 25 mm, vorzugsweise zwischen 12 und 23 mm, weiter bevorzugt zwischen 14 und 22 mm, besonders bevorzugt zwischen 15 und 21 mm, insbesondere zwischen 16 und 20 mm beträgt. In the exemplary embodiment it is provided that the thickness of the formwork skin 3, which is composed of the support plate 4 and the wear plate 5, is between 10 and 25 mm, preferably between 12 and 23 mm, more preferably between 14 and 22 mm, particularly preferably between 15 and 21 mm, in particular between 16 and 20 mm.
Im Ausführungsbeispiel ist vorgesehen, die Verschleißplatte 5 lösbar an der Tragplatte 4 festzulegen. Die Verschleißplatte 5 kann hierzu mit der Tragplatte 4 vorzugsweise vernagelt und/oder verschraubt und/oder vernietet und/oder lösbar verklebt sein. In the exemplary embodiment, it is provided that the wear plate 5 is detachably fixed on the support plate 4. For this purpose, the wear plate 5 can preferably be nailed and / or screwed and / or riveted and / or releasably glued to the support plate 4.
Zum Verkleben der Verschleißplatte 5 mit der Tragplatte 4 ist vorzugsweise ein lösbarer Klebstoff vorgesehen. A releasable adhesive is preferably provided for gluing the wear plate 5 to the support plate 4.
Die Tragplatte 4 weist Öffnungen 6a zum Lösen, insbesondere zum Auspressen der Verschleißplatte 5 auf. Ferner weist die Tragplatte 4 im Ausführungsbeispiel Bohrungen 6b zum Befestigen der Verschleißplatte 5, vorzugsweise um die Verschleißplatte 5 von hinten zu verschrauben bzw. durchzunieten, auf.The support plate 4 has openings 6a for releasing, in particular for pressing out the wear plate 5. Furthermore, in the exemplary embodiment, the support plate 4 has bores 6b for fastening the wear plate 5, preferably in order to screw or rivet through the wear plate 5 from behind.
Die Öffnungen 6a zum Lösen und die Bohrungen 6b zum Befestigen der Verschleißplatte 5 sind beispielhaft in der Figur 4 dargestellt. The openings 6a for releasing and the bores 6b for fastening the wear plate 5 are shown by way of example in FIG.
Die Tragplatte 4, insbesondere die Rückseite der Tragplatte 4, so wie diese in Figur 4 dargestellt ist, ist vorzugsweise lichtbeständig ausgeführt. Die Rückseite der Tragplatte 4 ist vorzugsweise derart gestaltet, dass sich diese zum Aufbringen eines Werbedrucks eignet und die Rückseite mit einem Hochdruckreiniger gereinigt werden kann, ohne dass es zu einer Beschädigung der Tragplatte 4 kommt. Figur 5 zeigt prinzipmäßig die Rückseite der Verschleißplatte 5. Die Verschleißplatte 5 weist vorzugsweise dieselbe Höhe und dieselbe Breite auf wie die Tragplatte 4. Die Verschleißplatte 5 kann in nicht näher dargestellter Weise Bohrungen aufweisen, um ein Verschrauben oder Vernieten mit der Trag platte 4 zu unterstützen. The support plate 4, in particular the rear side of the support plate 4, as shown in FIG. 4, is preferably designed to be light-resistant. The back of the support plate 4 is preferably designed in such a way that it is suitable for applying an advertising print and the back can be cleaned with a high-pressure cleaner without the support plate 4 being damaged. Figure 5 shows in principle the back of the wear plate 5. The wear plate 5 preferably has the same height and the same width as the support plate 4. The wear plate 5 can have holes in a manner not shown in order to support screwing or riveting with the support plate 4 .
In der Figur 6 ist eine spezifische Ausgestaltung der Tragplatte 4 dargestellt. Hierbei ist vorgesehen, dass die Tragplatte 4 in mehrere Tragplattensegmente 40, 41 , 42 unterteilt ist, die jeweils korrespondierende Segmente 7 des Rahmens 2 abdecken. Dargestellt sind in der Figur 6 drei Tragplattensegmente 40, 41 , 42, es können jedoch auch nur zwei Tragplattensegmente oder mehr als drei Trag platte nseg- mente vorgesehen sein. In the figure 6 a specific embodiment of the support plate 4 is shown. It is provided here that the support plate 4 is subdivided into several support plate segments 40, 41, 42, each of which covers corresponding segments 7 of the frame 2. Three support plate segments 40, 41, 42 are shown in FIG. 6, but only two support plate segments or more than three support plate segments can be provided.
Im Ausführungsbeispiel nach der Figur 6 ist vorgesehen, dass der Rahmen 2 an seiner der Tragplatte 4 zugewandten Vorderseite in Richtung auf die Tragplatte 4 hervorstehende Vorsprünge 8 aufweist, die die Segmente 7 des Rahmens 2 eingrenzen, wobei die Trag plattenseg mente 40, 41 , 42 derart in die Segmente 7 eingesetzt sind, dass jedes der Tragplattensegmente 40, 41 , 42 mit einer Kante 9 an wenigstens einem der Vorsprünge 8 anliegt und wenigstens ein an die Kante 9 angrenzender Randbereich der dem Rahmen 2 zugewandten Rückseite des Tragplattensegments 40, 41 , 42 an einer an den Vorsprung 8 angrenzenden Fläche der Vorderseite des Rahmens 2 anliegt. Dies ist in Figur 6 prinzipmäßig dargestellt. In the exemplary embodiment according to FIG. 6 it is provided that the frame 2 has on its front side facing the support plate 4 in the direction of the support plate 4 protruding projections 8 which delimit the segments 7 of the frame 2, the support plate segments 40, 41, 42 are inserted into the segments 7 in such a way that each of the support plate segments 40, 41, 42 rests with an edge 9 on at least one of the projections 8 and at least one edge region adjoining the edge 9 of the rear side of the support plate segment 40, 41, 42 facing the frame 2 rests against a surface of the front side of the frame 2 adjoining the projection 8. This is shown in principle in FIG.
Der Rahmen 2 mit den Vorsprüngen 8 ist somit derart gestaltet, dass eine Bewegung der Tragplattensegmente 40, 41 , 42 in der Ebene der Tragplattensegmente 40, 41 , 42 durch die Vorsprünge 8 begrenzt wird, wobei durch den Rahmen 2 bzw. durch die Gestaltung der Vorsprünge 8 ein Absatz ausgebildet wird, auf dem die Tragplattensegmente 40, 41 , 42 mit einem Randbereich ihrer Rückseite aufliegen können, so dass ein orthogonal zu der Ebene der Tragplattensegmente 40, 41 , 42 wirkender Betondruck von der Rückseite der Tragplattensegmente 40, 41 , 42 in den Absatz bzw. den Rahmen 2 eingeleitet werden kann. The frame 2 with the projections 8 is thus designed such that a movement of the support plate segments 40, 41, 42 in the plane of the support plate segments 40, 41, 42 is limited by the projections 8, whereby the frame 2 or the design of the Projections 8 a shoulder is formed on which the support plate segments 40, 41, 42 can rest with an edge region of their rear side, so that a concrete pressure acting orthogonally to the plane of the support plate segments 40, 41, 42 from the rear side of the support plate segments 40, 41, 42 can be introduced into the paragraph or the frame 2.
In Figur 6 ist ein Längsschnitt durch ein Rahmenschalungselement 1 dargestellt, das heißt ein Schnitt durch das Rahmenschalungselement 1 von dem oberen Rahmenquerteil 2b zum unteren Rahmenquerteil 2b. Die Tragplattensegmente 40, 41 , 42 sind somit übereinander angeordnet. Grundsätzlich kann jedoch auch vorgesehen sein, dass die Tragplattensegmente 40, 41 , 42 seitlich nebeneinander angeordnet sind, das heißt, dass die Tragplattensegmente 40, 41 , 42 nicht horizontal übereinander, sondern vertikal nebeneinander angeordnet sind. Grundsätzlich ist es auch möglich, dass die Tragplattensegmente 40,FIG. 6 shows a longitudinal section through a frame formwork element 1, that is to say a section through the frame formwork element 1 from the upper frame transverse part 2b to the lower frame transverse part 2b. The support plate segments 40, 41, 42 are thus arranged one above the other. In principle, however, it can also be provided that the support plate segments 40, 41, 42 are arranged laterally next to one another, that is, that the support plate segments 40, 41, 42 are not arranged horizontally one above the other, but vertically next to one another. In principle, it is also possible that the support plate segments 40,
41 , 42 sowohl seitlich nebeneinander als auch übereinander angeordnet sind, so dass die Tragplattensegmente 40, 41 , 42 ähnlich wie bei einem Schachbrett angeordnet sind und jeweils Segmente 7 des Rahmens 2 abdecken. 41, 42 are arranged both laterally next to one another and one above the other, so that the support plate segments 40, 41, 42 are arranged similarly to a chessboard and each cover segments 7 of the frame 2.
In Figur 7 ist prinzipmäßig ein Schalungssystem 11 mit (wenigstens) zwei Rahmenschalungselementen 1 und einer Mehrzahl von Ankerstäben 12, um die Rahmenschalungselemente 1 auf Abstand zueinander zu verspannen, dargestellt. Nach diesem Prinzip können in grundsätzlich bekannterWeise eine Mehrzahl von Rahmenschalungselementen 1 derart miteinander verbunden werden, dass diese gemeinsam eine Schalung zum Schalen eines verfestigbaren Baustoffs, insbesondere eines Betons, ausbilden. In Figur 7 ist examplarisch dargestellt, dass das Schalungssystem 11 durch zwei erfindungsgemäße Rahmenschalungselemente 1 gebildet ist. In Figure 7, a formwork system 11 is shown in principle with (at least) two frame formwork elements 1 and a plurality of tie rods 12 to brace the frame formwork elements 1 at a distance from one another. According to this principle, a plurality of frame formwork elements 1 can be connected to one another in a manner which is basically known in such a way that they together form a formwork for forming a solidifiable building material, in particular a concrete. In FIG. 7 it is shown by way of example that the formwork system 11 is formed by two frame formwork elements 1 according to the invention.
Grundsätzlich kann vorgesehen sein, dass nur ein Teil der Rahmenschalungselemente 1 erfindungsgemäß ausgerüstet ist. Es bietet sich jedoch an, alle Rahmenschalungselemente 1 erfindungsgemäß aus- zubilden, das heißt derart, dass die Schalhaut 3 durch eine Tragplatte 4 und eine Verschleißplatte 5 gebildet ist. Die Ankerstäbe 12 sind in Figur 7 nur prinzipmäßig dargestellt. Vorzugsweise ist dabei, wie dargestellt, vorgesehen, dass die Ankerstäbe 12 jeweils zwei Ankerkonen 13 aufweisen. Ferner sind in Figur 7 Ankerfixierungen in Form von Muttern 14 dargestellt, von denen jeweils zwei auf einen Ankerstab 12 aufgeschraubt sind, um die Rahmenschalungselemente 1 zu verspannen. Diese Darstellung ist rein exemplarisch. In principle, it can be provided that only some of the panel formwork elements 1 are equipped according to the invention. However, it is advisable to design all frame formwork elements 1 according to the invention, that is to say in such a way that the formwork skin 3 is formed by a support plate 4 and a wear plate 5. The anchor rods 12 are only shown in principle in FIG. Preferably, as shown, it is provided that the anchor rods 12 each have two anchor cones 13. Furthermore, anchor fixings in the form of nuts 14 are shown in FIG. 7, two of which are screwed onto an anchor rod 12 in order to brace the frame formwork elements 1. This representation is purely exemplary.
Zum Verspannen der Rahmenschalungselemente 1 kann eine einseitig oder zweiseitig bedienbare Ankertechnik eingesetzt werden, ferner kann auch die Verwendung von Distanzrohren bzw. Hüllrohren vorgesehen sein. An anchor technology that can be operated on one or both sides can be used to brace the frame formwork elements 1, and spacer tubes or jacket tubes can also be used.
