Description

Die Erfindung bezieht sich auf ein Schalungselement für eine Stirnabschalung.The invention relates to a formwork element for a Stirnabschalung.

Schalungselemente für Stirnabschalungen werden zur Abschalung von Stirnflächen von Betonbauteilen, insbesondere zur Trennung von nacheinander zu vergießenden Betonierabschnitten eingesetzt. Derartige Schalungselemente erzeugen je nach Ausgestaltung z. B. eine Arbeitsfuge oder eine Dehnfuge und sind häufig als verlorenes Schalungselement (siehe beispielsweise DE 20 2005 019 397 U1 ) ausgebildet, das im fertigen Betonteil verbleibt. Das Schalungselement wird quer zu den die Betonierabschnitte begrenzenden, seitlichen Schalungselementen eingebaut, hat jedoch eine Breite, die geringer ist als der Abstand zwischen den beiden Seitenschalungen. In den verbleibenden Zwischenraum zwischen dem Schalungselement und den Seitenschalungen wird eine sogenannte Betondeckungs- oder Dichtleiste eingebaut, die für einen Hohlraum beidseitig des Schalungselementes sorgt, der anschließend in geeigneter Weise und mit geeignetem Material, wie beispielsweise Beton oder Dichtungsmaterial oder dgl. verfüllt wird. Dadurch wird einerseits das Eindringen und Durchtreten von Feuchtigkeit an der durch das Schalungselement bewirkten Fuge verhindert und andererseits ein Abstand zwischen dem meist nicht korrosionsbeständigen Material des Schalungselementes und der Oberfläche des Betonteiles geschaffen, der dafür sorgt, dass beispielsweise ein aus nichtlegiertem Stahl bestehendes Schalungselement nicht rostet. Diese Betondeckungsleisten wurden bislang immer an den Seitenschalungen befestigt, insbesondere angenagelt. Dies konnte jedoch erst geschehen, nachdem die Seitenschalungen aufgebaut waren. Als Seitenschalungen werden jedoch häufig sogenannte Rahmenschalungen eingesetzt, die hochwertig und teuer sind. Diese Rahmenschalung wird durch das Annageln der Leisten beschädigt und muss nach jedem Einsatz ausgebessert werden, was wiederum sehr teuer und zeitaufwendig ist.Shuttering elements for Stirnabschalungen be used for shuttering of faces of concrete components, in particular for the separation of successive pouring concrete sections. Such formwork elements produce depending on the design z. As a construction joint or an expansion joint and are often as lost formwork element (see, for example DE 20 2005 019 397 U1 ), which remains in the finished concrete part. The formwork element is installed transversely to the concreting limiting lateral formwork elements, but has a width which is less than the distance between the two side molds. In the remaining space between the formwork element and the side molds a so-called Betondeckungs- or sealing strip is installed, which provides a cavity on both sides of the formwork element, which is then filled in a suitable manner and with suitable material, such as concrete or sealing material or the like. As a result, on the one hand prevents the penetration and passage of moisture to the joint caused by the formwork joint and on the other hand creates a distance between the usually non-corrosion resistant material of the formwork element and the surface of the concrete part, which ensures that, for example, a non-alloy steel formwork element does not rust , These concrete cover strips have always been attached to the side molds, especially nailed. However, this could happen only after the side molds were built. As a side formwork, however, so-called frame formwork is often used, which are high quality and expensive. This frame formwork is damaged by the nailing of the strips and must be repaired after each use, which in turn is very expensive and time-consuming.

Aus der DE 199 05 691 A1 (Fig. 8) ist ein Schalungselement bekannt, dessen Schalungstafel in seinen äußeren Randabschnitten von den Schenkeln U-förmiger Bügel durchdrungen wird, die Teil einer Korbstruktur des Schalungselements sind. Dadurch wird ein nach außen offener Befestigungswinkel gebildet, etwa zur Befestigung an Schalungsholzteilen.From the DE 199 05 691 A1 (Fig. 8), a formwork element is known, the formwork panel is penetrated in its outer edge portions of the legs U-shaped bracket, which are part of a basket structure of the formwork element. As a result, an outwardly open mounting bracket is formed, such as for attachment to formwork wood parts.

Der Erfindung liegt die Aufgabe zugrunde, ein Schalungselement bereitzustellen, dass einfach und schnell montierbar ist und keine Beschädigung der Rahmenschalung erfordert.The invention has for its object to provide a formwork element that is easy and quick to install and requires no damage to the frame formwork.

Die Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale gelöst.The object is solved by the features specified in claim 1.

Durch die erfindungsgemäße Ausgestaltung kann die Betondeckungsleiste an der Stirnabschalung befestigt werden, so dass die Rahmenschalung geschont wird, und was ggf. auch außerhalb des Schalungshohlraumes geschehen kann, da sich die Betondeckungsleisten immer im Bereich der Stirnabschalung befinden müssen. Die Abstütz- und Befestigungseinrichtung sorgt dafür, dass die Betondeckungsleiste ihre korrekte Lage erhält und diese beim Einbau der Stirnabschalung beibehält.The inventive design, the concrete cover strip can be attached to the Stirnabschalung, so that the frame formwork is spared, and what may possibly happen outside of the formwork cavity, since the Betondeckungsleisten must always be in the range of Stirnabschalung. The support and fastening device ensures that the Betondeckungsleiste receives its correct position and maintains this during installation of Stirnabschalung.

Vorteilhafte Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.Advantageous developments of the invention can be found in the dependent claims.

Die erfindungsgemäße Stirnabschalung ist auf einfache Weise als Halterung für eine durch beide Betonierabschnitte durchlaufende Bewehrung ausgebildet, da hier randseitig offene Aufnahmevertiefungen für die Bewehrung ausgebildet sind. Diese Aufnahmevertiefungen werden durch die Betondeckungsleiste verschlossen, so dass dadurch eine Lagesicherung für die Bewehrung erreicht wird.The invention Stirnabschalung is formed in a simple manner as a holder for a continuous through both concreting reinforcements, since here edge open receiving recesses are formed for the reinforcement. These receiving recesses are closed by the concrete cover strip, so that a position securing for the reinforcement is achieved.

Diese Lagesicherung wird noch verbessert, wenn die Aufnahmevertiefung als Passvertiefung ausgebildet, d.h. derart an die Abmessungen der üblichen, genormten Bewehrungsstäbe angepasst ist, dass der Bewehrungsstab fest oder nur mit minimalem Spiel in der Aufnahmevertiefung sitzt.This position assurance is further improved if the receiving recess formed as a fitting recess, i. adapted to the dimensions of the usual, standardized reinforcing bars, that the reinforcing rod sits firmly or only with minimal play in the receiving recess.

Aus den Fig. 1 bis 5 ist ein Schalungselement 1 ersichtlich, das als verlorene Stirnabschalung ausgebildet ist, d.h. im fertigen Beton verbleibt. Das Schalungselement 1 enthält eine Schalungswandung 2, die bevorzugt aus einem selektiv betondurchlässigen, d.h. durchbrochenen Material besteht, bevorzugt aus Streckmetall der unterschiedlichsten, auf dem Markt befindlichen Ausgestaltungen. Durch die Öffnungen der Schalungswandung 2 quillt beim Vergießen eines Betonierabschnittes der fließfähige Beton in begrenztem Maße hindurch, und zwar derart, dass er nach dem Aushärten auf der gegenüberliegenden Seite eine raue, gut anbindende Oberfläche hinterlässt.From the Fig. 1 to 5 is a formwork element 1 can be seen, which is designed as a lost Stirnabschalung, ie remains in the finished concrete. The formwork element 1 includes a formwork wall 2, which preferably consists of a selectively concrete permeable, ie perforated material, preferably made of expanded metal of different, located on the market embodiments. Through the openings of the formwork wall 2, when pouring a concreting section, the flowable concrete swells to a limited extent, in such a way that it leaves a rough, well-bonded surface after hardening on the opposite side.

Die Schalungswandung 2 enthält ebene Bereiche 2a bzw. 2b, die fluchtend zueinander ausgerichtet sind und eine Ebene E definieren, die die hauptsächliche Ebene der späteren Arbeitsfuge darstellt. Die übrige Ausgestaltung des Schalungselementes 1 ist nicht kritisch, sondern es hängt vom Anwendungszweck ab, ob das Schalungselement 1 beispielsweise mit einer trapezförmig aus der Ebene E herausgebogenen, mittleren Verzahnungsrippe 2c versehen ist, wie dies in Fig. 1 dargestellt ist, oder eine Halterung für eine Fugen- bzw. Wassersperre aufweist oder an andere Einsatzzwecke angepasst ist.The shuttering wall 2 includes planar portions 2a and 2b, respectively, which are aligned with each other and define a plane E which represents the principal plane of the later working joint. The remaining design of the formwork element 1 is not critical, but it depends on the application, whether the formwork element 1 is provided, for example, with a trapezoidal out of the plane E bent, central toothing rib 2c, as shown in Fig. 1 is shown, or has a holder for a joint or water barrier or adapted to other purposes.

Wenigstens ein, bevorzugt zwei gegenüberliegende Randbereiche der Schalungswandung 2 sind mit einer Abstütz- und Befestigungseinrichtung 3 für eine Betondeckungsleiste 4 versehen, die quer, bevorzugt rechtwinklig, zur Ebene E verlaufen und über die Ebene E vorstehen. In Fig. 1 ist, der besseren Übersicht halber, nur der in Fig. 1 hintere Randbereich 2e mit der Betondeckungsleiste 4 versehen, während die Betondeckungsleiste 4 am vorderen Randbereich 2d weggelassen wurde.At least one, preferably two opposite edge regions of the formwork wall 2 are provided with a supporting and fastening device 3 for a concrete cover strip 4, which extend transversely, preferably at right angles, to the plane E and protrude beyond the plane E. In Fig. 1 is, for better clarity, only in Fig. 1 Rear edge region 2e provided with the concrete cover strip 4, while the concrete cover strip 4 was omitted at the front edge portion 2d.

Die Abstütz- und Befestigungseinrichtung 3 für die Betondeckungsleiste 4 ist im dargestellten Ausführungsbeispiel als Abwinkelung des Randbereiches 2d bzw. 2e der Schalungswandung 2 ausgebildet, wobei die Ränder des biegbaren Streckmetallgitters der Schalungswandung 2 im Wesentlichen rechtwinklig zur Ebene E abgebogen wurden. Die abgewinkelten Randbereiche 2d bilden dadurch eine Auflagefläche 5 für die Betondeckungsleiste 4, die die Lage der Betondeckungsleiste 4 exakt vorgibt. Bevorzugt entspricht die Breite b des abgewinkelten Randbereiches 2d, 2e etwa der Breite B der Betondeckungsleiste 4. Die Abstütz- und Befestigungseinrichtung 3 enthält weiterhin Befestigungsmittel, die hier in wenigstens einer Öffnung 6 bestehen, die sich an geeigneter Stelle durch die Auflagefläche 5 erstreckt und die ein Befestigungsmittel, vorzugsweise eine Schraube 7 aufnehmen kann. Besteht das Schalungsmaterial der Schalungswandung 2 aus einem Streckmetall oder einem anderen durchbrochenen Material, wie beispielsweise einem Lochblech oder dgl., so können die dort bereits vorhandenen Löcher zum Einschrauben der Schrauben 7 verwendet werden.The support and fastening device 3 for the concrete cover strip 4 is formed in the illustrated embodiment as a bend of the edge region 2d or 2e of the formwork wall 2, wherein the edges of the bendable expanded metal mesh of the formwork wall 2 were bent substantially perpendicular to the plane E. The angled edge regions 2d thereby form a supporting surface 5 for the concrete cover strip 4, which specifies the position of the concrete cover strip 4 exactly. Preferably, the width b of the angled edge region 2d, 2e corresponds approximately to the width B of the concrete cover strip 4. The supporting and fastening device 3 further contains fastening means, which in this case consist in at least one opening 6 which extends at a suitable location through the support surface 5 extends and which can receive a fastening means, preferably a screw 7. If the formwork material of the formwork wall 2 consists of an expanded metal or another perforated material, such as a perforated plate or the like., The already existing there holes for screwing the screws 7 can be used.

Das erfindungsgemäße Schalungselement 1 enthält weiterhin Aufnahmevertiefungen 8, die zum Aufnehmen und Positionieren von Bewehrungsstäben 9 ausgebildet sind. Die Aufnahmevertiefungen 8 werden als Schlitze ausgeführt, die sich vom Randbereich 2d, 2e der Schalungswandung 2 in diese, im Wesentlichen senkrecht zur äußeren Kante, hineinerstrecken. Die Tiefe der Aufnahmevertiefungen 8 entspricht der Breite b der Auflagefläche 5 plus dem Durchmesser des Bewehrungsstabes 9. Die Höhe h der Aufnahmevertiefung 8 entspricht dem Durchmesser des Bewehrungsstabes 9. Zusätzlich ist der Grund bzw. die untere Begrenzung 8a jeder Aufnahmevertiefung 8 kreisförmig ausgerundet, wobei diese Maßnahme und die Abmessungen dazu führen, dass der Bewehrungsstab 9 in der Aufnahmevertiefung wie in einer Passvertiefung sitzt und dort lagefixiert ist. Je nach Dicke des Materials der Schalungswandung 2 im Bereich der abgewinkelten Ränder 2d, 2e kann auch die Materialdicke in die Abmessungen mit eingerechnet werden, so dass eine noch bessere Anpassung an die Abmessungen des Bewehrungsstabes, der genormt ist, möglich ist.The formwork element 1 according to the invention further comprises receiving recesses 8, which are designed for receiving and positioning of reinforcing bars 9. The receiving recesses 8 are designed as slots which extend from the edge region 2d, 2e of the shuttering wall 2 into this, substantially perpendicular to the outer edge. The depth of the receiving recesses 8 corresponds to the width b of the support surface 5 plus the diameter of the reinforcing rod 9. The height h of the receiving recess 8 corresponds to the diameter of the reinforcing rod 9. In addition, the bottom or lower boundary 8a of each receiving recess 8 is circularly rounded, this Measure and the dimensions cause the reinforcing rod 9 is seated in the receiving recess as in a fitting recess and is fixed in position there. Depending on the thickness of the material of the formwork wall 2 in the region of the angled edges 2d, 2e, the material thickness can also be included in the dimensions, so that an even better adaptation to the dimensions of the reinforcing rod, which is standardized, is possible.

Besteht die Schalungswandung 2 aus einem schneidbaren Material, so werden die Aufnahmevertiefungen 8 zweckmäßigerweise in das Material eingeschnitten.If the shuttering wall 2 consists of a cuttable material, the receiving recesses 8 are expediently cut into the material.

Das erfindungsgemäße Schalungselement wird bereits ab Werk vorgefertigt, wobei die Schalungswandung 2 zugeschnitten, mit den mittleren Strukturen, beispielsweise der trapezförmigen Verzahnungsrippe 2c durch Biegen versehen, die Aufnahmevertiefungen 8 eingeschnitten und die Randbereiche 2d, 2e im Wesentlichen senkrecht zur Ebene E derart hochgebogen werden, dass sie an derjenigen Seite der Ebene E, und nur an dieser Seite, vorstehen, an der die Betondeckungsleiste 4 angebracht werden soll. Sollte es jedoch erforderlich sein, die Betondeckungsleiste mittig zur Ebene E auszurichten, so kann dies entweder geschehen, indem die Betondeckungsleiste an den Abstütz- und Befestigungseinrichtungen 3 der Fig. 1 bezüglich der Ebene E mittig befestigt wird, oder die Randbereiche 2d, 2e zick-zack-förmig oder zwischen den Aufnahmevertiefungen abwechselnd zur einen oder zur anderen Seite abgebogen oder in anderer Weise ausgebildet werden. Nach dem Einlegen der Bewehrungsstäbe 9 werden die Betondeckungsleisten 4 mit Hilfe der Schrauben 7 an den Anlageflächen 5 festgeschraubt.The formwork element according to the invention is prefabricated from the factory, wherein the formwork wall 2 tailored, provided with the central structures, for example, the trapezoidal toothed rib 2c by bending, the receiving recesses 8 cut and the edge regions 2d, 2e are bent up substantially perpendicular to the plane E, that they project on that side of the plane E, and only on this side, to which the concrete cover strip 4 is to be attached. However, if it should be necessary to align the concrete cover strip centrally to the plane E, this can either be done by the concrete cover strip on the supporting and fastening devices 3 of Fig. 1 is fixed centrally with respect to the plane E, or the edge regions 2d, 2e zigzag-shaped or between the receiving recesses alternately bent to one or the other side or formed in any other way. After inserting the reinforcing bars 9, the concrete cover strips 4 are screwed by means of screws 7 to the contact surfaces 5.

Fig. 5 zeigt das erfindungsgemäße Schalungselement 1 eingebaut in eine Hauptschalung 10 zum Herstellen einer Wand. Die Hauptschalung 10 enthält Seitenschalungen 10a, 10b, dargestellt sind die üblichen Rahmenschalungen. An derjenigen Stelle, wo eine Trennung zwischen nacheinander zu vergießenden Betonierabschnitten stattfindet, wird das erfindungsgemäße Schalungselement eingebaut. Das Schalungselement 1 wird, insbesondere wenn es keine Aufnahmevertiefungen für die Bewehrung enthält, außerhalb der Hauptschalung 10 bereits mit den Betondeckungsleisten 4 versehen und als Einheit eingebaut. Enthält das erfindungsgemäße Schalungselement 1 die dargestellten, randseitigen offenen Aufnahmevertiefungen 8, so kann das Schalungselement 1 gleichzeitig als Lehre für die korrekte Positionierung der Bewehrung 9 dienen, das heißt durch die Aufnahmevertiefungen wird Lage und Abstand der Bewehrungsstäbe 9 der Längsbewehrung sowie der Stäbe 11 der Querbewehrung 11 festgelegt. Anschließend wird die Betondeckungsleiste an der Abstütz- und Befestigungseinrichtung 3 befestigt, beispielsweise durch die Schrauben 7 angeschraubt. Die Stellung der Schalung umfasst somit die folgenden Schritte:

  1. 1. Stellen der Rahmenschalung 10 - Hauptschalung (Außenseite)
  2. 2. Binden der Bewehrung 9 und 11 (Außenseite)
  3. 3. Einlegen und Einbinden des Abschalelementes 2
  4. 4. Anschrauben der Dichtleiste 4 (Außenseite)
  5. 5. Binden der Bewehrung 9 und 11 (Innenseite)
  6. 6. Anschrauben der Dichtleiste 4 (Innenseite)
  7. 7. Stellen der Rahmenschaltung 10 - Hauptschalung (Innenseite)
  8. 8. Bauseitige Abstützung der Stirnabschalung
Fig. 5 shows the formwork element 1 according to the invention installed in a main formwork 10 for producing a wall. The main formwork 10 includes side molds 10a, 10b, shown are the usual frame formwork. At the point where separation takes place between successive pouring concrete sections, the formwork element according to the invention is installed. The formwork element 1, in particular if it does not contain receiving recesses for the reinforcement, already provided outside the main formwork 10 with the concrete cover strips 4 and installed as a unit. Contains the formwork element 1 of the invention, the illustrated, edge-side open receiving recesses 8, the formwork element 1 can simultaneously serve as a teaching for the correct positioning of the reinforcement 9, that is by the receiving recesses position and distance of the reinforcing bars 9 of the longitudinal reinforcement and the rods 11 of the transverse reinforcement 11 set. Subsequently, the concrete cover strip is attached to the support and fastening device 3, for example, screwed by the screws 7. The position of the formwork thus comprises the following steps:
  1. 1. Setting the frame formwork 10 - main formwork (outside)
  2. 2. binding of reinforcement 9 and 11 (outside)
  3. 3. Inserting and integrating the Abschalelementes 2
  4. 4. Screw on the sealing strip 4 (outside)

In Abwandlung des beschriebenen und gezeichneten Ausführungsbeispiels ist die Erfindung auch bei Schalungselementen einsetzbar, die nicht von vorneherein mit Aufnahmevertiefungen für eine durchgehende Bewehrung versehen sind. Die Abstütz- und Befestigungseinrichtung kann weiterhin nur durch bereichsweise abgewinkelte oder bereichsweise vorgesehene Auflager gebildet werden. Bei nicht biegbarem Schalungsmaterial könnte die Abstütz- und Befestigungseinrichtung auch nachträglich angebracht werden.In a modification of the described and illustrated embodiment, the invention can also be used in formwork elements that are not provided from the outset with receiving recesses for a continuous reinforcement. The support and fastening device can continue to be formed only by partially angled or partially provided support. For non-flexible formwork material, the support and fastening device could also be retrofitted.
