Definitions
- the invention relates to a wall component according to the preamble of claim 1 and a method for producing an anchor for use in a wall component according to claim 1.
- Such a wall component can be found, for example, in DE-A-2 003 174.
- EP 02 58 205 B1 shows a wall component with an anchor, which is used in particular to position the formwork panels of a lost formwork and to absorb the forces acting on the formwork panels during concreting.
- the anchor consists of a first steel part that has undercuts and is screwed onto the inside of a formwork plate by means of a base plate.
- a second steel part of the armature has two interconnected, freely projecting plate-like Legs that are screwed onto another base plate on the inside of the other formwork plate. At the free end of the legs, recesses are formed which can be locked with the undercuts of the first steel part.
- the invention has for its object to provide a wall component of the type mentioned, with which a safe mutual positioning of the plates is guaranteed in a simple manner, and to provide a method that allows a fast and inexpensive manufacture of an anchor used.
- the anchor of the wall component according to the invention thus has the shape of a spatial frame which has high stability, in particular tensile, compressive and torsional rigidity.
- a passage is formed between the web bodies and the spacer legs, which enables the insertion of reinforcing steel and at the same time serves to a certain extent for its positioning.
- wood or a wood-based material for the web bodies these can be produced and processed in a simple and cost-effective manner, if appropriate from waste material. Due to the inherent stability of the anchor, it can be prefabricated at the factory and easily attached to the panels as a compact component.
- the spacer legs serve essentially to determine the positions of the web bodies relative to one another and the Recording of the tensile forces that occur, for example, during concreting and act perpendicular to the plane of the slabs. If, however, in a preferred development of the invention, the length of the spacer legs corresponds to the mutual spacing of the plates, the spacer legs also act as spacers for the plates, so that they can be reliably aligned and held parallel to one another.
- a simple geometric shape for the anchor can be achieved if the spacer legs are plate-shaped. It is preferably provided that the end faces of the spacer legs and the outer sides of the respective web body form a flat surface. The anchor thus lies against a relatively large area on the inside of the plates and can hold them securely. Gluing of the web body to the plates can also be provided, if necessary also only as an auxiliary assembly measure.
- the side surfaces of the web body and the side surfaces of the spacer legs lie in one plane, with a simple manufacture of the armature, for example by means of cutting to length, being achieved by a prefabricated carrier.
- the anchors are arranged parallel to one another, the bending stiffness in certain directions may not be sufficient. It can therefore be provided that the anchors in different, each rotated by 90 ° Fix positions on the plates, which increases the spatial stability of the wall component.
- the spacer legs preferably also consist of a wood material, in particular of solid wood or chipboard. In this way, the whole anchor is made of wood, so that the individual parts can be joined together in a simple manner. However, it is also possible for the spacer legs to be formed from a sheet metal.
- a simple and quick connection of the individual components of the armature can be achieved if the web body is cuboidal made of solid wood, since in this way there are flat contact surfaces between the web body and the spacer legs.
- the spacer legs are attached to the web bodies with nails or clips.
- the nails or staples extend perpendicular to the grain of the wood. This can be ensured in that the end piece of the web body is essentially perpendicular to the plates and to the longitudinal extension of the spacer legs.
- the spacer legs and the web body are glued together.
- fasteners preferably nails or clamps
- the nails or staples are preferably introduced by means of NC-controlled nailing or stapling machines which fire the nails or staples into the components to be connected using compressed air in exact and reproducible positions. It has proven useful to coat the nails or staples with a resin before attaching them. The resin is liquefied by the frictional heat that is released when the shot is fired in, and can thus fill any cavities in the immediate vicinity of the nail or the clamp and provide additional gluing. The resin then solidifies again, resulting in great adhesion of the nails or staples in the wood. Additionally or alternatively, it is also possible to glue the anchors to the plates.
- a wall component is thus created from two spaced-apart panels, which can be filled with concrete, for example, as prefabricated formwork on the construction site.

Abstract
Description
Die Erfindung betrifft ein Wandbauelement nach dem Oberbegriff des Anspruchs 1sowie ein Verfahren zur Herstellung eines Ankers zur Verwendung in einem Wandbauelement nach Anspruch 1.The invention relates to a wall component according to the preamble of claim 1 and a method for producing an anchor for use in a wall component according to claim 1.
Ein derartiges Wandbauelement geht beispielsweise aus der DE-A-2 003 174 hervor.Such a wall component can be found, for example, in DE-A-2 003 174.
In der EP 02 58 205 B1 ist ein Wandbauelement mit einem Anker gezeigt, der insbesondere zur Positionierung der Schalplatten einer verlorenen Schalung und zur Aufnahme der beim Betonieren auf die Schalplatten einwirkenden Kräfte dient. Der Anker besteht aus einem ersten Stahlteil, das Hinterschneidungen aufweist und auf der Innenseite über eine Grundplatte auf eine der Schalplatten aufgeschraubt wird. Ein zweites Stahlteil des Ankers weist zwei miteinander verbundene, frei auskragende plattenartige Schenkel auf, die über eine weitere Grundplatte auf der Innenseite der anderen Schalplatte angeschraubt werden. Am freien Ende der Schenkel sind Ausnehmungen ausgebildet, die mit den Hinterschneidungen des ersten Stahlteils verrastbar sind.EP 02 58 205 B1 shows a wall component with an anchor, which is used in particular to position the formwork panels of a lost formwork and to absorb the forces acting on the formwork panels during concreting. The anchor consists of a first steel part that has undercuts and is screwed onto the inside of a formwork plate by means of a base plate. A second steel part of the armature has two interconnected, freely projecting plate-like Legs that are screwed onto another base plate on the inside of the other formwork plate. At the free end of the legs, recesses are formed which can be locked with the undercuts of the first steel part.
Um die beim Betonieren auftretenden Belastungen der Schalplatten zuverlässig aufnehmen zu können, ist es notwendig, die Schalplatten über eine Vielzahl von Ankern aneinander zu befestigen, wobei die Anker in einem engen Raster angeordnet sind. Um ein sicheres Verrasten der beiden Stahlteile jedes Ankers gewährleisten zu können, müssen die vorbestimmten Rastermaße mit sehr hoher Genauigkeit eingehalten werden. Da die einzelnen Stahlteile auf die Schalplatten aufgeschraubt werden, ist diese Forderung nur mit hohem zeitlichem und auch konstruktivem Aufwand erfüllbar. Darüber hinaus sind die Stahlteile aufwendig und kostenintensiv in ihrer Herstellung.In order to be able to reliably absorb the loads on the formwork panels that occur during concreting, it is necessary to fasten the formwork panels to one another via a large number of anchors, the anchors being arranged in a narrow grid. In order to ensure that the two steel parts of each anchor can be securely locked, the predetermined grid dimensions must be adhered to with very high accuracy. Since the individual steel parts are screwed onto the formwork panels, this requirement can only be met with great expenditure of time and construction. In addition, the steel parts are complex and costly to manufacture.
Es ist versucht worden, aus Kunststoff bestehende Anker der genannten Art mit den Schalplatten zu verkleben. Obwohl mit einer Klebeverbindung eine ausreichende Haltekraft zwischen der Schalplatte und den Ankern erzielbar ist, ist eine derartige Anbringung fertigungstechnisch ungünstig, da der Kleber relativ lange Abbindezeiten aufweist, so daß die Schalplatten mit den Ankern bis zu der Austrocknung des Klebers zwischengelagert werden müssen. Darüber hinaus ist es relativ schwierig und aufwendig, eine gleichmäßige und vollflächige Aufbringung des Klebers sicherzustellen. Desweiteren ist eine Klebverbindung von der Mikrostruktur der Oberfläche der zu verklebenden Bauteile abhängig, wodurch Klebverbindungen bestimmter Festigkeit nur schwierig reproduzierbar sind.Attempts have been made to bond plastic anchors of the type mentioned to the formwork panels. Although a sufficient holding force between the formwork plate and the anchors can be achieved with an adhesive connection, such an attachment is disadvantageous in terms of production technology, since the adhesive has relatively long setting times, so that the formwork plates with the anchors have to be temporarily stored until the adhesive dries out. In addition, it is relatively difficult and expensive to ensure that the adhesive is applied evenly and over the entire surface. Furthermore, an adhesive bond is dependent on the microstructure of the surface of the components to be bonded, as a result of which adhesive bonds of certain strength are difficult to reproduce.
Der Erfindung liegt die Aufgabe zugrunde, ein Wandbauelement der eingangs genannten Art zu schaffen, mit dem in einfacher Weise eine sichere gegenseitige Positionierung der Platten gewährleistet ist, sowie ein Verfahren vorzusehen, das eine schnelle und kostengünstige Herstellung eines dabei verwendeten Ankers erlaubt.The invention has for its object to provide a wall component of the type mentioned, with which a safe mutual positioning of the plates is guaranteed in a simple manner, and to provide a method that allows a fast and inexpensive manufacture of an anchor used.
Diese Aufgabe wird erfindungsgemäß hinsichtlich des Wandbauelementes mit den im kennzeichnenden Teil des Patentanspruchs 1 enthaltenen Merkmalen gelöst.This object is achieved with regard to the wall component with the features contained in the characterizing part of claim 1.
Der Anker des erfindungsgemäßen Wandbauelementes besitzt somit die Gestalt eines räumlichen Rahmens, der eine hohe Stabilität, insbesondere Zug-, Druck- und Torsionssteifigkeit aufweist. Dabei ist zwischen den Stegkörpern und den Distanzschenkeln ein Durchlaß gebildet, der das Einsetzen von Bewehrungsstahl ermöglicht und gleichzeitig in gewissem Grade dessen Positionierung dient. Durch die Verwendung von Holz oder einem Holzwerkstoff für die Stegkörper sind diese in einfacher und kostengünstiger Weise, gegebenenfalls aus Verschnittmaterial, herstellbar und verarbeitbar. Aufgrund der Eigenstabilität des Ankers kann dieser fabrikseitig vorgefertigt und in einfacher Weise als ein kompaktes Bauteil an den Platten befestigt werden.The anchor of the wall component according to the invention thus has the shape of a spatial frame which has high stability, in particular tensile, compressive and torsional rigidity. In this case, a passage is formed between the web bodies and the spacer legs, which enables the insertion of reinforcing steel and at the same time serves to a certain extent for its positioning. By using wood or a wood-based material for the web bodies, these can be produced and processed in a simple and cost-effective manner, if appropriate from waste material. Due to the inherent stability of the anchor, it can be prefabricated at the factory and easily attached to the panels as a compact component.
Die Distanzschenkel dienen im wesentlichen der Festlegung der Positionen der Stegkörper relativ zueinander sowie der Aufnahme der beispielsweise beim Betonieren auftretenden, senkrecht zur Ebene der Platten wirkenden Zugkräfte. Wenn jedoch in bevorzugter Weiterbildung der Erfindung die Länge der Distanzschenkel dem gegenseitigen Abstand der Platten entspricht, wirken die Distanzschenkel auch als Abstandshalter für die Platten, so daß diese in zuverlässiger Weise parallel zueinander ausgerichtet und gehalten werden können. Eine einfache geometrische Form für den Anker kann erreicht werden, wenn die Distanzschenkel plattenförmig ausgebildet sind. Vorzugsweise ist dabei vorgesehen, daß die Stirnseiten der Distanzschenkel und die Außenseiten des jeweiligen Stegkörpers eine ebene Fläche bilden. Somit liegt der Anker über eine relativ große Fläche an der Innenseite der Platten an und kann diese sicher halten. Auch kann eine Verleimung der Stegkörper mit den Platten, gegebenenfalls auch nur als Montagehilfsmaßnahme vorgesehen sein.The spacer legs serve essentially to determine the positions of the web bodies relative to one another and the Recording of the tensile forces that occur, for example, during concreting and act perpendicular to the plane of the slabs. If, however, in a preferred development of the invention, the length of the spacer legs corresponds to the mutual spacing of the plates, the spacer legs also act as spacers for the plates, so that they can be reliably aligned and held parallel to one another. A simple geometric shape for the anchor can be achieved if the spacer legs are plate-shaped. It is preferably provided that the end faces of the spacer legs and the outer sides of the respective web body form a flat surface. The anchor thus lies against a relatively large area on the inside of the plates and can hold them securely. Gluing of the web body to the plates can also be provided, if necessary also only as an auxiliary assembly measure.
Die Seitenflächen des Stegkörpers und die Seitenflächen der Distanzschenkel liegen in einer Ebene, wobei eine einfache Herstellung des Ankers, beispielsweise mittels Ablängen, von einem vorgefertigten Träger erreicht werden.The side surfaces of the web body and the side surfaces of the spacer legs lie in one plane, with a simple manufacture of the armature, for example by means of cutting to length, being achieved by a prefabricated carrier.
Wenn alle Anker parallel zueinander angeordnet sind, kann gegebenenfalls die Biegesteifigkeit in bestimmten Richtungen nicht ausreichend sein. Es kann deshalb vorgesehen sein, die Anker in verschiedenen, jeweils um 90° gedrehte Positionen an den Platten zu befestigen, wodurch die räumliche Stabilität des Wandbauelementes erhöht ist.If all anchors are arranged parallel to one another, the bending stiffness in certain directions may not be sufficient. It can therefore be provided that the anchors in different, each rotated by 90 ° Fix positions on the plates, which increases the spatial stability of the wall component.
Vorzugsweise bestehen auch die Distanzschenkel aus einem Holzwerkstoff, insbesondere aus Massivholz oder Spanplatten. Auf diese Weise besteht der ganze Anker aus Holz, so daß die einzelne Teile in einfacher Weise zusammengefügt werden können. Es ist jedoch auch möglich, daß die Distanzschenkel von einem Blech gebildet sind.The spacer legs preferably also consist of a wood material, in particular of solid wood or chipboard. In this way, the whole anchor is made of wood, so that the individual parts can be joined together in a simple manner. However, it is also possible for the spacer legs to be formed from a sheet metal.
Eine einfache und schnelle Verbindung der einzelnen Bauteile des Ankers läßt sich erreichen, wenn der Stegkörper quaderförmig aus Massivholz ausgebildet ist, da auf diese Weise zwischen dem Stegkörper und den Distanzschenkeln ebene Kontaktflächen gegeben sind.A simple and quick connection of the individual components of the armature can be achieved if the web body is cuboidal made of solid wood, since in this way there are flat contact surfaces between the web body and the spacer legs.
Dabei ist in bevorzugter Ausführung der Erfindung vorgesehen, daß die Distanzschenkel mit Nägeln oder Klammern an den Stegkörpern angebracht sind. In diesem Fall ist es sinnvoll, wenn die Nägel oder Klammern sich senkrecht zur Faserrichtung des Holzes erstrecken. Dies kann dadurch sichergestellt werden, daß das Stirnholz des Stegkörpers im wesentlichen senkrecht zu den Platten und zur Längserstreckung der Distanzschenkel liegt.It is provided in a preferred embodiment of the invention that the spacer legs are attached to the web bodies with nails or clips. In this case it makes sense if the nails or staples extend perpendicular to the grain of the wood. This can be ensured in that the end piece of the web body is essentially perpendicular to the plates and to the longitudinal extension of the spacer legs.
Zusätzlich oder alternativ dazu kann vorgesehen sein, daß die Distanzschenkel und die Stegkörper miteinander verleimt sind.Additionally or alternatively, it can be provided that the spacer legs and the web body are glued together.
Zur Montage der Anker an den Platten, die vorzugsweise von Spanplatten oder ähnlichen Holzwerkstoffplatten gebildet sind, werden von der Außenseite der Platte Befestigungsmittel, vorzugsweise Nägel oder Klammern, eingebracht und durch die Platte hindurch in die Stegkörper getrieben, wodurch die Anker fest an der Platte angebracht sind.To mount the anchors on the plates, which are preferably formed of chipboard or similar wood-based panels, fasteners, preferably nails or clamps, are introduced from the outside of the plate and driven through the plate into the web body, as a result of which the anchors are firmly attached to the plate are.
Vorzugsweise erfolgt das Einbringen der Nägel oder Klammern mittels NC-gesteuerter Nagel- bzw. Klammermaschinen, die die Nägel oder Klammern mittels Druckluft in exakten und reproduzierbaren Positionen in die zu verbindenden Bauteile schießen. Dabei hat es sich bewährt, die Nägel oder Klammern vor ihrer Anbringung mit einem Harz zu überziehen. Das Harz wird durch die beim Einschießen frei werdende Reibungswärme verflüssigt und kann dadurch eventuelle Hohlräume in unmittelbarer Umgebung des Nagels oder der Klammer ausfüllen und auf eine zusätzliche Verklebung sorgen. Anschließend verfestigt sich das Harz wieder, wodurch eine große Haftung der Nägel oder Klammern in dem Holz erreicht wird. Zusätzlich oder alternativ dazu ist jedoch auch möglich, die Anker mit den Platten zu verleimen.The nails or staples are preferably introduced by means of NC-controlled nailing or stapling machines which fire the nails or staples into the components to be connected using compressed air in exact and reproducible positions. It has proven useful to coat the nails or staples with a resin before attaching them. The resin is liquefied by the frictional heat that is released when the shot is fired in, and can thus fill any cavities in the immediate vicinity of the nail or the clamp and provide additional gluing. The resin then solidifies again, resulting in great adhesion of the nails or staples in the wood. Additionally or alternatively, it is also possible to glue the anchors to the plates.
Es ist somit ein Wandbauelement aus zwei in Abstand gehaltenen Platten geschaffen, das beispielsweise als vorgefertigte Schalung auf der Baustelle mit Beton verfüllt werden kann. Dabei kann bei der werkseitigen Anbringung der Anker gleichzeitig die für das Bauteil notwendige Bewehrung in dem Wandbauelement eingelegt werden. Desweiteren können auch die Heizungs- und/oder Elektro- und/ oder Sanitärinstallationen vorgenommen werden.A wall component is thus created from two spaced-apart panels, which can be filled with concrete, for example, as prefabricated formwork on the construction site. When the anchors are attached at the factory, the reinforcement required for the component can be inserted in the wall component at the same time. Furthermore, the heating and / or electrical and / or sanitary installations can also be carried out.
Alternativ dazu ist es auch möglich, das Wandbauelement als Trennwand ohne Lastabtragungsfunktion zu verwenden und den zwischen den Platten befindlichen Zwischenraum beispielsweise mit Isolier- oder Dämmaterial auszufüllen.Alternatively, it is also possible to use the wall component as a partition without a load transfer function and to fill the space between the plates with, for example, insulating or insulating material.
Zur erfindungsgemäßen Lösung der Aufgabe hinsichtlich des Verfahrens zur Herstellung eines Ankers zur Verwendung bei einem Wandbauelement nach Anspruch 1 sind folgende Schritte vorgesehen: Anordnen zweier Holzleisten im Abstand parallel zueinander, Aufbringen und Befestigen jeweils einer Platte an der Ober- und der Unterseite der Holzleisten zur Bildung eines Verbundträgers und Ablängen eines Ankers gewünschter Breite von dem Verbundträger senkrecht zur Längsrichtung der Holzleisten. In relativ kurzer Zeit kann somit eine Vielzahl von Ankern mit einem hohlen Rechteckprofil aus einem Verbundträger großer Länge gewonnen werden, wobei im Bedarfsfall die Breite der Anker leicht verändert werden kann.In order to achieve the object according to the invention with regard to the method for producing an anchor for use in a wall component according to claim 1, the following steps are provided: arranging two wooden strips at a distance from one another in parallel, applying and fastening one plate each to the top and bottom of the wooden strips for formation a composite beam and cutting an anchor of the desired width from the composite beam perpendicular to the longitudinal direction of the wooden strips. In a relatively short time, a large number of anchors with a hollow rectangular profile can thus be obtained from a composite girder of great length, and the width of the anchors can be easily changed if necessary.
