- EP-A-0 560 308 for example, the wall panel made of expanded metal.
- Expanded metal as such is less expensive than Perforated sheet and also has the advantage that better interlocking between the blackboard and the concrete is reached.
- the disadvantage is that blackboards, which are made entirely of expanded metal and have only low inherent rigidity and therefore have to be additionally stiffened. Also through profiling the expanded metal panels can hardly achieve the required rigidity. For this reason, the expanded metal panels in the known formwork elements stiffened by welded metal round rods. However, this leads at a considerably higher production cost and thus at higher costs.
- a steel / concrete composite structure in which the Steel element is a profiled plate, which is made of alternating strips of solid sheet metal and expanded metal.

- Expanded metal sheets are usually produced in one cycle working machine, which has a series of slots in it every working cycle Sheet metal punches and the material then stretches so that a row of stitches is formed becomes. The material is then transported on until the next cycle begins.
- the wall panel of the formwork element according to the invention can just create yourself, each time after a certain number of steps the material is transported further without punching and stretching, so that you get a solid sheet strip in the desired width. With that The panel made of expanded metal and solid sheet run as a result perpendicular to the direction of stretch of the expanded metal.
- a wall panel profiled in the running direction of the strips can be used with a suitable one Select the profile in the direction perpendicular to the running direction.
- the wall panel has an approximately trapezoidal profile which the solid sheet strips are not or only weakly profiled and the base sides of the trapezoids form, while the expanded metal the oblique flanks of the Trapeze forms. If the blackboard is then bent perpendicular to the direction of the profile or is folded, the solid sheet strips only set one relative to the deformation little resistance.
- the inside with respect to the bending curvature Solid sheet strips are subjected to pressure when bending or edging and dodge outwards so that they are bent relatively sharply, while the outer solid sheet strips are bent more gently.
- the Expanded metal allows the balance between the different deformations the solid sheet strip. In this way, the blackboard can be added to the bend quiver according to the invention.
- the quiver points out that recesses must be provided on the bending lines high stability at the edges.

Description
Die Erfindung betrifft ein Schalungselement in der Form eines Köchers mit einer Wandtafel aus durchbrochenem Metall. Solche Schalungselemente werden für verlorene Betonschalungen eingesetzt, beispielsweise als Köcherschalungen, wie in DE-U-94 06 373 beschrieben wird.The invention relates to a formwork element in the form of a quiver with a Openwork metal wall panel. Such formwork elements are used for lost concrete formwork used, for example as quiver formwork, such as is described in DE-U-94 06 373.
Bei den in der oben genannten Druckschrift beschriebenen Schalungselementen wird die Wandtafel durch vorzugsweise profiliertes Lochblech gebildet.In the formwork elements described in the above-mentioned document the wall panel is formed by preferably profiled perforated plate.
Andererseits ist es beispielsweise aus EP-A-0 560 308 bekannt, die Wandtafel aus Streckmetall herzustellen. Streckmetall als solches ist kostengünstiger als Lochblech und hat zudem den Vorteil, daß eine bessere Verzahnung zwischen der Wandtafel und dem Beton erreicht wird. Nachteilig ist jedoch, daß Wandtafeln, die ganz aus Streckmetall bestehen, nur eine geringe Eigensteifheit aufweisen und deshalb zusätzlich versteift werden müssen. Auch durch eine Profilierung der Streckmetalltafeln läßt sich die notwendige Steifheit kaum erreichen. Aus diesem Grund werden die Streckmetalltafeln bei den bekannten Schalungselementen durch aufgeschweißte Metall-Rundstäbe versteift. Dies führt jedoch zu einem beträchtlich größeren Herstellungsaufwand und damit zu höheren Kosten.On the other hand, it is known from EP-A-0 560 308, for example, the wall panel made of expanded metal. Expanded metal as such is less expensive than Perforated sheet and also has the advantage that better interlocking between the blackboard and the concrete is reached. The disadvantage, however, is that blackboards, which are made entirely of expanded metal and have only low inherent rigidity and therefore have to be additionally stiffened. Also through profiling the expanded metal panels can hardly achieve the required rigidity. For this reason, the expanded metal panels in the known formwork elements stiffened by welded metal round rods. However, this leads at a considerably higher production cost and thus at higher costs.
Aus WO-A-9105121 ist eine Stahl/Beton-Verbundstruktur bekannt, bei der das Stahlelement eine profilierte Platte ist, die aus abwechselnden Steifen aus Vollblech und Streckmetall besteht. Dabei sind die Vollblechstreifen als rippenartige Versteifungsprofile geformt, die der Platte in der Richtung quer zur Laufrichtung der Streifen eine hohe Biegesteifheit geben.From WO-A-9105121 a steel / concrete composite structure is known, in which the Steel element is a profiled plate, which is made of alternating strips of solid sheet metal and expanded metal. The solid sheet strips are rib-like Stiffening profiles shaped that the plate in the direction transverse to the direction of travel the strips give a high degree of flexural rigidity.
Aufgabe der Erfindung ist es, ein Schalungselement, insbesondere in der Form eines Köchers für Köcherschalungen, zu schaffen, das kostengünstig herstellbar ist. eine gute Verzahnung mit dem Beton ergibt und dennoch eine hohe Stabilität aufweist.The object of the invention is to provide a formwork element, in particular in the form of a quiver for quiver formwork, which is inexpensive to manufacture. results in good interlocking with the concrete and is still very stable.
Diese Aufgabe wird mit den in Patentanspruch 1 angegebenen Merkmalen gelöst.This object is achieved with the features specified in claim 1.
Bei dieser Lösung wird die Wandtafel des Schalungselements durch eine abwechselnde Folge paralleler, einstückig miteinander verbundener Streifen aus Streckmetall und Vollblech gebildet.With this solution, the wall panel of the formwork element is replaced by an alternating one Follow parallel, one-piece strips Expanded metal and solid sheet formed.
Die Herstellung von Streckmetalltafeln erfolgt üblicherweise mit einer taktweise arbeitenden Maschine, die in jedem Arbeitstakt eine Reihe von Schlitzen in das Blech stanzt und das Material dann streckt, so daß eine Maschenreihe gebildet wird. Anschließend wird das Material weiter transportiert, bis der nächste Taktzyklus beginnt. Die Wandtafel des erfindungsgemäßen Schalungselements läßt sich einfach herstellen, indem jeweils nach einer bestimmten Anzahl von Taktschritten ein Weitertransport des Materials ohne Stanzen und Strecken erfolgt, so daß man einen Vollblechstreifen in der gewünschten Breite erhält. Bei der so hergestellten Wandtafel verlaufen folglich die Streifen aus Streckmetall und Vollblech senkrecht zur Streckrichtung des Streckmetalls.Expanded metal sheets are usually produced in one cycle working machine, which has a series of slots in it every working cycle Sheet metal punches and the material then stretches so that a row of stitches is formed becomes. The material is then transported on until the next cycle begins. The wall panel of the formwork element according to the invention can just create yourself, each time after a certain number of steps the material is transported further without punching and stretching, so that you get a solid sheet strip in the desired width. With that The panel made of expanded metal and solid sheet run as a result perpendicular to the direction of stretch of the expanded metal.
Die auf diese Weise in die Wandtafel eingearbeiteten Streifen aus Vollblech bilden eine integrierte Versteifung, durch die die Stabilität der Wandtafel erhöht wird, ohne daß zusätzliche Versteifungselemente angeschweißt werden müssen. Die zwischen den Vollblechstreifen vorhandenen Streifen aus Streckmetall gewährleisten eine gute Verzahnung mit dem Beton.Form the strips of solid sheet that are worked into the wall panel in this way an integrated stiffening which increases the stability of the wall panel without additional stiffening elements having to be welded on. Ensure the strips of expanded metal between the solid sheet strips good interlocking with the concrete.
Selbst eine in Laufrichtung der Streifen profilierte Wandtafel kann bei geeigneter Wahl des Profils in der zur Laufrichtung senkrechten Richtung gebogen werden. Erfindungsgemäß hat die Wandtafel ein annähernd trapezförmiges Profil, bei dem die Vollblechstreifen nicht oder nur schwach profiliert sind und die Grundseiten der Trapeze bilden, während das Streckmetall die schrägen Flanken der Trapeze bildet. Wenn die Wandtafel dann senkrecht zur Profilrichtung gebogen oder gekantet wird, setzen die Vollblechstreifen der Verformung nur einen relativ geringen Widerstand entgegen. Die in bezug auf die Biegekrümmung innen liegenden Vollblechstreifen werden beim Biegen oder Kanten auf Druck beansprucht und weichen nach außen aus, so daß sie relativ scharf abgeknickt werden, während die außenliegenden Vollblechstreifen sanfter gebogen werden. Das Streckmetall gestattet den Ausgleich zwischen den unterschiedlichen Verformungen der Vollblechstreifen. Auf diese Weise läßt sich die Wandtafel zu dem erfindungsgemäßen Köcher biegen.Even a wall panel profiled in the running direction of the strips can be used with a suitable one Select the profile in the direction perpendicular to the running direction. According to the wall panel has an approximately trapezoidal profile which the solid sheet strips are not or only weakly profiled and the base sides of the trapezoids form, while the expanded metal the oblique flanks of the Trapeze forms. If the blackboard is then bent perpendicular to the direction of the profile or is folded, the solid sheet strips only set one relative to the deformation little resistance. The inside with respect to the bending curvature Solid sheet strips are subjected to pressure when bending or edging and dodge outwards so that they are bent relatively sharply, while the outer solid sheet strips are bent more gently. The Expanded metal allows the balance between the different deformations the solid sheet strip. In this way, the blackboard can be added to the bend quiver according to the invention.
Da das Wandmaterial trotz der Profilierung gekantet werden kann, ohne daß Aussparungen an den Biegelinien vorgesehen werden müssen, weist der Köcher an den Kanten eine hohe Stabilität auf. Es ist deshalb problemlos möglich, den Köcher zu Transportzwecken in einen flachen Zustand zu überführen, indem er rautenförmig von zwei diagonal gegenüberliegenden Ecken aus zusammengedrückt wird. Auf der Baustelle lädt sich der Köcher dann wieder in den gebrauchsfertigen Zustand zurückverformen. Dieser Vorgang kann sogar mehrfach wiederholt werden, ohne daß es zu einer übermäßigen Materialermüdung an den Biegelinien kommt.Since the wall material can be folded despite the profiling without The quiver points out that recesses must be provided on the bending lines high stability at the edges. It is therefore easily possible To bring quiver into a flat state for transportation purposes by diamond-shaped pressed together from two diagonally opposite corners becomes. At the construction site, the quiver is then loaded back into the ready-to-use Reshape condition. This process can even be repeated can be repeated without causing excessive material fatigue comes at the bend lines.

Das in Figur 1 gezeigte Schalungselement hat die Form einer flachen Wandtafel
10, die in einem Stück aus einem einlagigen Stahlblech hergestellt ist, das eine
Dicke von beispielsweise 1 mm aufweist. Das Blech ist abschnittsweise geschlitzt
und verstreckt, so daß mehrere parallele Streifen 12 aus Vollblech gebildet
werden, die durch dazwischenliegende Streifen 14 aus Streckmetall miteinander
verbunden sind. Die Streckrichtung des Streckmetalls ist senkrecht zur
Laufrichtung der Streifen 12, 14.The formwork element shown in Figure 1 has the shape of a
Im gezeigten Beispiel haben die Streifen 12, 14 annähernd dieselbe Breite. Das
Breitenverhältnis kann je nach Stabilitätsanforderungen variiert werden. Vorzugsweise
sollten jedoch die Streckmetallstreifen jeweils eine Breite von mindestens
drei oder vier Maschen haben.In the example shown, the
Figur 2 zeigt ein Schalungselement in der Form eines Köchers 16, dessen Wände
18 in einem Stück aus einer Wandtafel 10 der in Figur 1 gezeigten Art hergestellt
sind. Hierzu wird die Wandtafel 10 zunächst in Laufrichtung der Streifen
12, 14 profiliert, wie beispielsweise in Figur 3 oder 4 gezeigt ist. Das
Vollblech bildet dann zwei Scharen miteinander abwechselnder und annähernd
in zwei versetzten Ebenen liegender Streifen 12, 12', die die Kämme
und Täler des Profils bilden, während die Streifen 14 aus Streckmetall im
wesentlichen die Profilflanken bilden. Die so profilierte Wandtafel wird dann
an vier senkrecht zur Laufrichtung des Profils verlaufenden Biegelinien 20 gebogen,
und die freien Enden werden miteinander verschweißt, so daß man
den in Figur 2 gezeigten Köcher erhält, der die Form einer quadratischen
oder rechteckigen Säule hat.Figure 2 shows a formwork element in the form of a
Die Streifen 12, die in bezug auf den Köcher weiter außen liegen, werden
beim Biegen an den Biegelinien 20 sanft gerundet. Durch diese Rundungen
wird die Stabilität des Köchers gegenüber dem von außen anstehenden Druck
des Betons beträchtlich erhöht. Die weiter innen liegenden Streifen 12 werden
dagegen an den Biegezonen auf Druck beansprucht, und stülpen sich unter
Bildung relativ scharfer Knickstellen 22 nach außen. Die Streifen 12' liegen
somit in der Fläche der Wände 18 gegenüber den Streifen 12 nach innen
zurück, sind jedoch zu den Biegelinien 20 hin leicht nach außen geschwungen,
so daß die Knickstellen 22 im wesentlichen mit den gerundeten Bereichen
der Streifen 12 bündig sind. Auf diese Weise werden im wesentlichen
geradlinig durchgehende Biegelinien gebildet, die eine relativ leichte Verformung
des Materials gestatten. Die unterschiedlichen Verformungen der
Streifen 12 und 12' werden im Bereich der Biegelinien durch das relativ
leicht dehnbare und stauchbare Streckmetall 14 ausgeglichen.The
Das Profil der Wandtafel 10 bzw. der Wände 18 des Köchers 16 kann auf vielfältige
Weise variiert werden. Während bei dem in Figur 3 gezeigten Beispiel
die Streifen 12, 12' flach sind, kann es aus Stabilitätsgründen zweckmäßig
sein, diese Steifen aus Vollmetall ihrerseits leicht zu profilieren. Figur 4 zeigt
als Beispiel ein leicht gerundetes Profil der Streifen 12, 12'. Wahlweise können
diese Streifen auch ein dreieckiges oder trapezförmiges Profil haben, so
daß sie auch Teile der in der Hauptsache durch das Streckmetall gebildeten
Profilflanken bilden.The profile of the
Grundsätzlich ist es auch möglich, das Profil umzukehren, so daß die Streifen
14 aus Streckmetall die Kämme und Täler bilden, während die Profilflanken
durch Vollblech gebildet werden. Basically, it is also possible to reverse the profile so that the
Bei einem Köcher kann für die Wände 18 auch das in Figur 5 gezeigte Profil
verwendet werden. Hier sind die Streifen 14 Teile einer durchgehenden
Streckmetalltafel, auf die einzelne Streifen 12, 12' aus Vollblech aufgeschweißt
sind. Die Streifen 12, 12' können profiliert oder unprofiliert sein.
Im gezeigten Beispiel sind sie abwechselnd auf entgegengesetzten Seiten der
Streckmetalltafel angebracht. Sie können jedoch auch auf derselben Seite der
Streckmetalltafel angeordnet sein. Bei der Herstellung werden vorzugsweise
die Streifen aus Vollmetall zunächst in flachem Zustand auf die flache Streckmetalltafel
aufgeschweißt, und anschließend werden das Streckmetall und
das Vollblech in einem Arbeitsgang profiliert. Das Profil kann dann in ähnlicher
Weise wie die Profile nach Figuren 3 und 4 zu dem Köcher 16 gebogen
werden.In the case of a quiver, the profile shown in FIG. 5 can also be used for the
Da bei dieser Ausführungsform auf der dem Beton zugewandten Außenseite des Köchers eine größere Oberfläche durch das Streckmetall gebildet wird (bei Anordnung der Vollblechstreifen auf der Innenseite sogar die gesamte Oberfläche), läßt sich eine noch bessere Verzahnung mit dem Beton erreichen.Because in this embodiment on the outside facing the concrete of the quiver a larger surface is formed by the expanded metal (If the solid sheet strips are arranged on the inside, even the entire one Surface), an even better interlocking with the concrete can be achieved.
Aufgrund der großen Biegsamkeit an den Biegelinien 20 ist es auch möglich,
den Köcher 16 während des Transports rautenförmig zusammenzudrücken,
wie in Figur 6 gezeigt ist. Hierdurch lassen sich das Transportvolumen und
die Transportkosten beträchtlich reduzieren. Auf der Baustelle kann der Köcher
wieder problemlos in den gebrauchsfertigen Zustand gemäß Figur 2 zurückverformt
werden.Because of the great flexibility at the bending lines 20, it is also possible to
press the
Es besteht auch die Möglichkeit, in den Köcher 16 einen nicht gezeigten Boden
einzulegen, der gleichfalls aus einer Wandtafel mit einem Profil der in Figuren
3 bis 5 gezeigten Art versehen sein kann. Der Boden kann mit zwei gegenüberliegenden
Rändern in das Profil der Wände 18 eingreifen oder auf
einwärts gekröpften Abwinklungen an den unteren Enden der Wände 18 aufliegen.
Aufgrund der durch das Streckmetall gebildeten Durchbrüche ist der
Boden in wünschenswerter Weise für Wasser durchlässig.There is also the possibility of a bottom, not shown, in the
