Description
Titel:Title:
Elementschalung zur Herstellung von Arbeits- und Dehnfugen im Beton
und Stahlbetonbau.
Stand der Technik: Element formwork for the production of working and expansion joints in concrete and reinforced concrete construction.
State of the art:
Bei der Herstellung von Arbeitsfugen in Betonwänden oder Platten wird
üblicherweise ein auf die jeweilige Wandstärke zugeschnittenes starkes Brett, an der vorgesehenen Stelle der Arbeitsfuge, zwischen
die äußere und innere Wandschalung eingestellt, und mit Drängbrettern etc. gegen den auftretenden Betondruck gesichert. Eine Durchführung
der Bewehrungsstähle durch oben genanntes Brett ist nur mit hohem Aufwand möglich, welcher beim Ausschalen meist die Zerstörung des
Brettes zur Folge hat.
Problem: When creating construction joints in concrete walls or slabs, a strong board cut to the respective wall thickness is usually placed between the outer and inner wall formwork at the intended location of the construction joint and secured against the concrete pressure using pressure boards, etc. It is only possible to pass the reinforcing steel through the above-mentioned board with great effort, which usually results in the board being destroyed when the formwork is removed.
Problem:
Der im Schutzanspruch 1-4 angegebenen Erfindung liegt das Problem zugrunde, ein Schalungselement herzustellen, welches universell für verschiedene Wandstärken und praktisch unbegrenzt oft einsetzbar ist. Weiterhin soll an der Arbeitsfuge eine Nut entstehen und eine Durchführung der Bewehrungsstähle möglich sein.The invention specified in claims 1-4 is based on the problem of producing a formwork element that is universally applicable for different wall thicknesses and can be used practically unlimitedly. Furthermore, a groove should be created at the construction joint and it should be possible to pass through the reinforcing steel.
Diese Probleme werden mit den in den Schutzansprüchen 1-4 beschriebenen
Merkmalen gelöst.
Erreichte Vorteile: These problems are solved with the features described in claims 1-4.
Benefits achieved:
Mit der Erfindung lassen sich problemlos Arbeits- und Dehnfugen im Beton- und Stahlbetonbau herstellen. Das Schalelement ist universell für verschiedene Wand- oder Plattenstärken einsetzbar. Es ist gegenüber herkömmlichen Ausführungen mehrfach, praktisch unbegrenzt oft, einsetzbar. Die Durchführung der Bewehrungsstähle an der Arbeitsfuge ist problemlos möglich. Die Kosten für vorgefertigte Bewehrungsanschlüsse entfallen.The invention makes it easy to create construction and expansion joints in concrete and reinforced concrete construction. The formwork element can be used universally for different wall or slab thicknesses. It can be used multiple times, practically unlimitedly, compared to conventional designs. The reinforcing steel can be installed in the construction joint without any problems. The costs for prefabricated reinforcement connections are eliminated.
Weitere Ausgestaltung der Erci.-Beim
Herstellen von wasserdichtem Beton wird in der Arbeitsfuge Bodenplatte - Wand meist ein Fugenblech oder ein Elastomerefugenband
eingebaut. In diesem Fall kann das Schalelement im unteren Bereich mit einer Auskerbung für das Fugenband versehen werden,
und in die trapezförmige Nut ein auf voller Wandhohe durchgehendes
Quellfugenband eingeklebt werden.
Darstellung der Erfindung Further design of the Erci.- When producing waterproof concrete, a joint sheet or an elastomer joint tape is usually installed in the construction joint between the floor slab and the wall. In this case, the formwork element can be provided with a notch for the joint tape in the lower area, and an expansion joint tape can be glued into the trapezoidal groove that runs the full height of the wall.
Description of the invention
Ein Ausführungsbeispiel wird anhand der Figur 1 bis 4 erläutert.
Es zeigen

Das Schalelement besteht aus einem Stahlblechprofil (1) u-förmig abgekantet ca. 14 cm breit und ca. 2,50 cm lang, je nach bauseits vorhandener Wandschalungshöhe. Zur Aussteifung sind zwei Rohre (6) eingeschweißt, welche auch als Tragegriff dienen.The formwork element consists of a sheet steel profile (1) bent in a U-shape, approx. 14 cm wide and approx. 2.50 cm long, depending on the existing wall formwork height on site. Two tubes (6) are welded in for reinforcement, which also serve as a carrying handle.
In Fig. 1 ist das. Element für eine Wandstärke von 24 cm montiert dargestellt. Am Stahlblechprofil (1) (evtl. alt. Alu) ist rechts und links je ein Kantholz 8/5 cm (2) mit je 3 Grobgewindeschrauben (3) befestigt, welches mit Auskerbungen (4) zum Durchführen der Bewehrungsstäbe (5) versehen ist. Das montierte Element wird wie in Fig. 2 dargestellt am gewünschten Platz der Arbeitsfuge zwischen den Wandschalungstafeln (7) mittels Drängbrett (14) fixiert.In Fig. 1, the element is shown assembled for a wall thickness of 24 cm. On the right and left of the sheet steel profile (1) (possibly old aluminum), an 8/5 cm squared timber (2) is attached with 3 coarse thread screws (3) each, which is provided with notches (4) for the reinforcing bars (5) to pass through. The assembled element is fixed at the desired location of the construction joint between the wall formwork panels (7) using a pressure board (14), as shown in Fig. 2.
In Fig. 2 sieht man die Hüemenciächalung für eine Wandstäke von 30 cm montiert in eingebautem Zustand. Hierfür wird zwischen Kantholz (2) und Blechprofil (1) ein 3 cm starkes Brett (2.1) mit eingebaut. Die Bewehrungseisen (5) können nach der Montage des Schalelements zwischen den beiden Wandschalungstafeln (7) eingeführt werden. Nach Betonieren bzw. Abbinden des Betons werden die Wandschalungen entfernt. Danach löst man die Grobgewindeschrauben (3) und kann die beiden äußeren Kanthölzer (2) abnehmen. Nach leichtem Auseinanderdrücken der Bewehrungsstäbe läßt sich das Stahlblechprofil (1) herausnehmen. Als Ergebnis sieht man It. Fig. 4 den ersten Betonierabschnitt mit trapezförmiger Nut (12) und vorstehenden Bewehrungsstählen (5). Damit die Betonwand bzw. die Arbeitsfuge wasserdicht wird, ist in die Nut (12) ein Quellband (13) einzukleben. Nun können die Wandschalungen (7) zum zweiten Betonierabschnitt montiert werden.In Fig. 2 you can see the roof formwork for a wall thickness of 30 cm installed in the installed state. For this purpose, a 3 cm thick board (2.1) is installed between the squared timber (2) and the sheet metal profile (1). The reinforcing iron (5) can be inserted between the two wall formwork panels (7) after the formwork element has been installed. After the concrete has been poured or the concrete has set, the wall formwork is removed. Then the coarse thread screws (3) are loosened and the two outer squared timbers (2) can be removed. After slightly pushing the reinforcing bars apart, the sheet steel profile (1) can be removed. The result is the first concreting section with a trapezoidal groove (12) and protruding reinforcing steel (5) in Fig. 4. In order to make the concrete wall or the construction joint watertight, an expansion band (13) must be glued into the groove (12). The wall formwork (7) can now be assembled for the second concreting section.
