Description

Die Erfindung bezieht sich auf eine Schalung für den Betonbau gemäß Oberbegriff Patentanspruch 1 sowie auf eine Vorrichtung zum Herstellen dieser Schalung.The invention relates to a formwork for concrete construction according to the preamble of claim 1 and to a device for producing this formwork.

Bekannt sind Schalungselemente, insbes. auch solche für Köcherschalungen (DE-GM 90 01 890.7), die aus einem Schalungsmaterial hergestellt sind, welche eine schwalbenschwanzförmige Profilierung aufweist.Formwork elements are known, in particular also those for quiver formwork (DE-GM 90 01 890.7), which are made from a formwork material which has a dovetail-shaped profile.

Dieses Schalungsmaterial, welches als Flachmaterial, vorzugsweise als Stahlblech mit der Profilierung ausgebildet ist, hat u.a. den Vorteil, daß sich dieses Schalungsmaterial trotz einer ausreichenden Steifigkeit für die Herstellung der Schalung bzw. eines Schalungselementes auch um eine quer bzw. senkrecht zur Profilierung verlaufende Biegelinie biegen bzw. abwinkeln läßt, ohne daß eine Verbreiterung des Materials beim Biegen oder Knicken im Bereich der Biegelinie auftritt, wie dies bei einer anderen Profilierung, beispielsweise bei einer wellenförmigen Profilierung, d.h. bei einer wellenblechartigen Ausbildung des Schalungsmaterials der Fall wäre.This formwork material, which is designed as a flat material, preferably as a steel sheet with the profiling, has, among other things. the advantage that this formwork material can be bent or angled about a transverse or perpendicular to the profile bending line despite sufficient rigidity for the production of the formwork or a formwork element without widening the material when bending or kinking in the area of Bending line occurs, as is the case with another profiling, for example with a wavy profiling, ie would be the case with a corrugated sheet-like design of the formwork material.

Durch die schwalbenschwanzförmige Profilierung des Schalungsmaterials hat dieses darüberhinaus auch den Vorteil einer verbesserten Einbindung im Beton, so daß bei im Beton verbleibendem Schalungsmaterial zwischen zwei im Bereich dieses Schalungsmaterials aneinander anschließenden Betonbauteilen ein in statischer und in dynamischer Hinsicht wesentlich verbesserter Übergang erreicht wird.Due to the dovetail-shaped profiling of the formwork material, this also has the advantage of an improved integration in the concrete, so that in the formwork material remaining in the concrete between two adjoining concrete components in the area of this formwork material, a transition that is significantly improved in static and dynamic terms is achieved.

Der Erfindung liegt die Aufgabe zugrunde, unter Beibehaltung der vorgenannten Vorteile eine Schalung so auszubilden, daß im Bedarfsfall auch ein einfaches und unproblematisches Anschließen zweier Enden des Schalungsmaterials möglich ist.The invention is based on the object, while maintaining the aforementioned advantages, form a formwork so that, if necessary, a simple and unproblematic connection of two ends of the formwork material is possible.

Zur Lösung dieser Aufgabe ist eine Schalung entsprechend dem kennzeichnenden Teil des Patentanspruches 1 ausgebildet.To solve this problem, a formwork is formed according to the characterizing part of claim 1.

Bei der erfindungsgemäßen Schalung ist das Schalungsmaterial im Bereich eines von zwei miteinander zu verbindenden Enden derart umgeformt, daß das nach der Umformung im Bereich dieses Endes erhaltene Profil in die schwalbenschwanzförmigen Profilabschnitte des anderen Endes paßt, d.h. ein Verbinden der beiden Enden durch Aufeinanderlegen bzw. Aufeinanderdrücken dieser Enden möglich ist. Im Verbindungsbereich überlappen sich die beiden Enden mit den ursprünglichen, unveränderten schwalbenschwanzförmigen Profilabschnitten sowie mit den umgeformten Profilabschnitten. Auch im Bereich dieser Verbindung bleibt somit letztlich zumindest an einer Seite der Schalung die besonders vorteilhafte schwalbenschwanzförmige Profilierung voll erhalten.In the formwork according to the invention, the formwork material is reshaped in the area of one of two ends to be connected to one another such that the profile obtained after reshaping in the area of this end fits into the dovetail-shaped profile sections of the other end, i.e. a connection of the two ends is possible by placing these ends on or pushing them together. In the connection area, the two ends overlap with the original, unchanged dovetail-shaped profile sections and with the reshaped profile sections. In the area of this connection, the particularly advantageous dovetail-shaped profiling ultimately remains fully retained at least on one side of the formwork.

Die Umformung ist vorzugsweise so gewählt, daß das umgeformte Ende auf das nicht umgeformte Ende leicht klemmend oder druckknopfartig aufgedrückt werden kann.The reshaping is preferably chosen so that the reshaped end can be pressed onto the non-reshaped end in a slightly clamping or push-button manner.

Das umgeformte Profil ist beispielsweise ein dreieckförmiges, trapezförmiges oder dergleichen hinterschneidungsloses Profil, bevorzugt ein zumindest annähernd rechteckförmiges oder quadratisches Profil.The reshaped profile is, for example, a triangular, trapezoidal or similar undercut-free profile, preferably an at least approximately rectangular or square profile.

Bevorzug ist die erfindungsgemäße Schalung so ausgebildet, daß das Schalungsmaterial wenigstens einmal oder aber mehrfach abgewinkelt bzw. abgebogen ist, und zwar entsprechend einer senkrecht zur Profilierung verlaufenden Knicklinie, wobei im umgeformten Bereich des Schalungsmaterials keine Abwinklung vorgesehen ist.The formwork according to the invention is preferably designed in such a way that the formwork material is angled or bent at least once or several times, in accordance with a crease line running perpendicular to the profile, with no bending being provided in the deformed area of the formwork material.

In den Figuren ist 1 ein Schalungsmaterial, welches von mehreren, miteinander verbundenen Streifen 2 eines profilierten Stahlbleches gebildet sind. In der Figur 1 sind nur zwei Streifen 2 wiedergegeben. Die Streifen 2 sind an ihren Längskanten durch speziell geformte, formschlüssig ineinandergreifende Profilabschnitte 3 und 4 aneinander gehalten bzw. miteinander verbunden. Ansonsten sind die Streifen 2 mit einer schwalbenschwanzförmigen Profilierung versehen, d.h. jeder Streifen 2 besitzt bei der dargestellten Ausführungsform zwei schwalbenschwanzförmige Profilabschnitte 5, die bei der für die Figuren 1 - 3 gewählten Darstellung über eine Ebene E, in deren Bereich die Profilabschnitte 3 und 4 vorgesehen sind, vorstehen und sich in Längsrichtung der Streifen 2, d.h. parallel zu den Profilabschnitten 3 und 4 und damit senkrecht zu der Zeichenebene der Figuren 1 - 3 erstrecken.In the figures, 1 is a formwork material which is formed by a plurality of strips 2 of a profiled steel sheet which are connected to one another. In Figure 1, only two strips 2 are shown. The strips 2 are held together or connected to one another at their longitudinal edges by specially shaped, form-fitting interlocking profile sections 3 and 4. Otherwise, the strips 2 are provided with a dovetail-shaped profile, i.e. in the embodiment shown, each strip 2 has two dovetail-shaped profile sections 5 which, in the illustration selected for FIGS. 1-3, protrude over a plane E, in the area of which the profile sections 3 and 4 are provided, and which extend in the longitudinal direction of the strips 2, i.e. extend parallel to the profile sections 3 and 4 and thus perpendicular to the drawing plane of FIGS. 1-3.

An ihrer der Ebene E entfernt liegenden Seite besitzen die Profilabschnitte 5 eine größere Breite a. Im Bereich der Ebene E besitzen die Profilabschnitte 5 eine kleinere Breite b. Der Zwischenraum 6 zwischen den Profilabschnitten 5 bildet ebenfalls ein Schwalbenschwanzprofil, welches mit dem Profil der Profilabschnitte 5 identisch ist, d.h. im Bereich der Ebene E die größere Breite A und im Abstand von dieser Ebene die kleinere Breite b besitzt.On its side remote from plane E, the profile sections 5 have a greater width a. In the area of level E, the Profilab cuts 5 a smaller width b. The space 6 between the profile sections 5 likewise forms a dovetail profile which is identical to the profile of the profile sections 5, ie has the greater width A in the region of the plane E and the smaller width b at a distance from this plane.

Durch das Schwalbenschwanzprofil läßt sich das Schalungsmaterial 1 ohne Schwierigkeiten senkrecht zur Längserstreckung der Streifen 2 bzw. der Profilabschnitte 5 knicken, insbesondere auch ohne daß eine Verbreiterung des Materials. Hierdurch ist es möglich, geschlossene Schalungselemente, beispielsweise das Schalungselement 7 der Fig. 5 für Köcherschalungen herzustellen. Hierfür wird beispielsweise entsprechend der Fig. 4 eine Länge eines Schalungsmaterials 1 verwendet, welches insgesamt vier über die Profilabschnitte 3 und 4 miteinander verbundene Streifen 2 aufweist. Das Schalungsmaterial wird dann an insgesamt vier Bereichen 8 senkrecht zur Profilierung geknickt, was durch das Schwalbenschwanzprofil ohne weiteres möglich ist, da sich beim Knicken die schrägen Seiten dieses Profils der Ebene E annähern können. Um den in der Fig. 7 dargestellten Rohling 7' an den beiden Enden des geknickten Schalungsmaterials 1 zu der Schalung 7 verbinden zu können, ist das Profil des Schalungsmaterial an dem einen Ende des Rohlings 7', d.h. im Bereich des dortigen Endes 9 entsprechend der Fig. 2 derart umgeformt, daß das Schalungsmaterial an diesem Ende 9 anstelle der schwalbenschwanzförmigen Profilierung eine rechteckförmige Profilierung aufweist, und zwar mit Rechteckprofilabschnitten 10 dort, wo ursprünglich die Profilabschnitte 5 vorgesehen waren, wobei die Rechteckprofilabschnitte 10 in der Ebene E eine Breite b besitzen, die in etwa gleich der Breite b ist. Die Zwischenräume 11 zwischen den Profilabschnitten besitzen eine Breite a', die in etwa gleich der Breite a ist. Durch diese Umformung des Schalungsmaterials am Ende 9 ist es möglich, das Ende 9 mit dem anderen Ende des geknickten Schalungsmaterials bzw. des Rohlings 7' zu dem Schalungselement 7 zu verbinden, und zwar dadurch, daß jeder Profilabschnitt 10 in einen Profilabschnitt 5 eingeschoben wird, wie dies auch in der Fig. 3 im Detail dargestellt ist. Die beiden Enden 9 und 12 sind dabei bereits mit Klemmsitz aneinander gehalten. Zur Fixierung werden noch Nieten oder andere Befestigungselemente 13 verwendet.Due to the dovetail profile, the formwork material 1 can easily be bent perpendicularly to the longitudinal extent of the strips 2 or the profile sections 5, in particular without the material being widened. This makes it possible to produce closed formwork elements, for example the formwork element 7 of FIG. 5 for quiver formwork. For this purpose, for example, according to FIG. 4, a length of formwork material 1 is used which has a total of four strips 2 connected to one another via the profile sections 3 and 4. The formwork material is then bent at a total of four areas 8 perpendicular to the profiling, which is easily possible due to the dovetail profile, since the inclined sides of this profile can approach plane E when buckling. In order to be able to connect the blank 7 'shown in Fig. 7 to the formwork 7 at both ends of the bent formwork material 1, the profile of the formwork material is to be attached to one end of the blank 7', i.e. 2 such that the formwork material at this end 9 has a rectangular profile instead of the dovetail-shaped profile, with rectangular profile sections 10 where the profile sections 5 were originally provided, the rectangular profile sections 10 in the plane E has a width b which is approximately equal to the width b. The spaces 11 between the profile sections have a width a 'which is approximately equal to the width a. This reshaping of the formwork material at the end 9 makes it possible to connect the end 9 to the other end of the bent formwork material or the blank 7 'to form the formwork element 7, namely by inserting each profile section 10 into a profile section 5, as is also shown in detail in FIG. 3. The two ends 9 and 12 are already held together with a clamp fit. Rivets or other fastening elements 13 are also used for fixing.

Bei geringem, notwendigem Transportvolumen kann das Schalungselement 7 bevorzugt in Form des Rohlings 7' mit bereits umgeformten Ende 9 vom Hersteller an den Verwendungsort geliefert werden.With a small, necessary transport volume, the formwork element 7 can preferably be supplied to the place of use by the manufacturer in the form of the blank 7 'with the end 9 already formed.

Zum Umformen des Endes 9 dient ein Formwerkzeug, welches aus einem stempelartigen Werkzeugteil 15 und einer passenden Matrize besteht. Das Umformwerkzeug 14 ist so ausgeführt, daß mit ihm jeweils das Ende eines Streifens 2 umgeformt werden kann. Hierfür wird das Material zwischen die beiden Werkzeugteile 15 und 16 eingelegt. Durch das Schließen des Werkzeugs erfolgt das Umformen. Bevorzugt ist das Umformwerkzeug 14 gleichzeitig als Schneid- und Stanzwerkzeug ausgebildet, mit dem das das Schalungselement 7 bzw. den Rohling 7' bildende Material auf die erforderliche Länge abgeschnitten bzw. getrennt und Öffnungen für die Befestigungsmittel 13 eingestanzt werden.A shaping tool, which consists of a stamp-like tool part 15 and a suitable die, is used to deform the end 9. The forming tool 14 is designed so that the end of a strip 2 can be formed with it. For this purpose, the material is inserted between the two tool parts 15 and 16. Forming takes place by closing the tool. The forming tool 14 is preferably designed at the same time as a cutting and punching tool, with which the material forming the formwork element 7 or the blank 7 ′ is cut or separated to the required length and openings for the fastening means 13 are punched in.

Dadurch, daß das Schalungsmaterial 1 von mehreren, miteinander verbundenen relativ schmalen Streifen 2 gebildet ist, sind die für das Umform- werkzeug 14 beim Umformen notwendigen Kräfte relativ klein.Because the formwork material 1 is formed by a plurality of relatively narrow strips 2 which are connected to one another, the forces required for the forming tool 14 during the forming are relatively small.

Wie in der Fig. 1 bei 17 angedeutet ist, weisen das Schalungsmaterial 1 bzw. die Streifen 2 jeweils in den von der schwalbenschwanzförmigen Profilierung gebildeten Ecken bzw. in den Ecken der Profilabschnitte 5 Öffnungen 17 auf, die in Längsrichtung der Streifen 2, d.h. in der Achsrichtung senkrecht zur Zeichenebene der Fig. 1 aufeinanderfolgend vorgesehen sind und einen effektiven Querschnitt aufweisen, der so gewählt ist, daß beim Betonieren zwar in den Profilabschnitten 5 oder einem Teil dieser Profilabschnitte eingeschlossene Luft entweichen kann, ein nennenswerter bzw. störender Durchtritt von Beton an diesen Öffnungen 17 aber nicht auftritt.As indicated in Fig. 1 at 17, the formwork material 1 or the strips 2 each have openings 17 in the corners formed by the dovetail-shaped profile or in the corners of the profile sections 5, which in the longitudinal direction of the strips 2, i.e. 1 are provided in succession in the axial direction perpendicular to the plane of the drawing in FIG. 1 and have an effective cross section which is selected such that air enclosed in profile sections 5 or part of these profile sections can escape during concreting, a noteworthy or disruptive passage of concrete but does not occur at these openings 17.

Die Erfindung wurde voranstehend an einem Ausführungsbeispiel beschrieben. Es versteht sich, daß Änderungen sowie Abwandlungen möglich sind, ohne daß dadurch der der Erfindung zugrundeliegende Erfindungsgedanke verlassen wird.The invention has been described above using an exemplary embodiment. It goes without saying that changes and modifications are possible without thereby departing from the inventive idea on which the invention is based.
