Description
Doppellasche für Schalungszwingen Die Erfindung betrifft eine aus einem- Stück bestehende Doppellasche- für- Schalungszwingen mit den außerhalb der Kreuzungsstelle der Zwingenenden liegenden Laschenschenkeln.Double tab for formwork clamps The invention relates to a one-piece existing double flap for formwork clamps with the outside of the Crossing point of the clamp ends lying flap legs.
Das Neue besteht darin, daß die Laschenschenkel durch eine aus der Mittelebene des einen Schenkels in die des anderen gebogene Versteifungsrippe miteinander verbunden sind. Durch die Verbindung der beiden Laschenschenkel mit einer Versteifungsrippe wird eine gleichmäßige Kräfteverteilung und bei ebenso starker Ausbildung der Lasche, wie bisher üblich, eineweit größere Festigkeit, Widerstandsfähigkeit und damit Lebensdauer der Lasche erreicht. Außerdem kann die Rippe infolge ihrer besonderen Form im Querschnitt schwächer bemessen und dadurch das Gewicht und die Haltbarkeit der Lasche günstig beeinflußt werden.The new thing is that the flap legs are replaced by one of the Central plane of one leg in the other bent stiffening rib with each other are connected. By connecting the two flap legs with a stiffening rib an even distribution of forces and with an equally strong formation of the tab, as usual, far greater strength, resistance and thus service life reached the tab. In addition, due to its special shape in cross section, the rib can dimensioned weaker and therefore the weight and durability of the flap favorable to be influenced.
Die Zeichnungen stellen eine Ausführung einer Doppellasche gemäß der Erfindung beispielsweise dar.The drawings represent an embodiment of a double flap according to FIG Invention, for example.
Abb. 1 veranschaulicht die Verwendung der Doppellasche für eine Betonform.Fig. 1 illustrates the use of the double link for a concrete form.
Abb. z zeigt die Doppellasche schaubildlich. Abb. 3 und q. veranschaulichen die besondere Form der Versteifungsrippe.Fig. Z shows a diagram of the double flap. Fig. 3 and q. illustrate the special shape of the stiffening rib.
Zur Herstellung einer z. B. im Querschnitt geviertigen Säule aus Beton wird die Form für diese Säule aus Brettern 11 zusammengesetzt und um die Bretter die Schalungszwinge gelegt. Diese besteht im wesentlichen aus gelenkig miteinander verbundenen Armen 12,13 bzw. 15, 16, die so an die Form angelegt werden, daß ihre Gelenkpunkte an gegenüberliegenden Ecken liegen. Auf die sich kreuzenden Enden der beiden Stangenpaare wird dann je eine Doppellasche 18 aufgeschoben und durch Einschlagen je eines Feiles 34 in schlitzförmige Öffnungen 33 der Laschenschenkel 1g, 23 und schlitzförmige Öffnungen 32 der Arme 12, 13, 15, 16 fest angezogen.To produce a z. B. in cross-section quartered concrete column the form for this column is assembled from boards 11 and around the boards the formwork clamp placed. This consists essentially of articulated with each other connected arms 12,13 or 15, 16, which are applied to the form that their Articulation points are at opposite corners. On the crossing ends of the A double flap 18 is then pushed on each of the two pairs of rods and knocked in one file 34 each in slot-shaped openings 33 of the tab legs 1g, 23 and slot-shaped openings 32 of the arms 12, 13, 15, 16 are tightened.
Wie- Abb: 2 veranschaulicht, ist die Doppellasche so ausgebildet, daß die Laschenschenkel lg und 23 vom Kreuzungspunkt der Arme 12 und 16 bzw. 13 -und 15 nach außen liegen und durch eine Versteifungsrippe 30 miteinander verbunden sind. Diese Rippe ist aus der Mittelebene des einen Schenkels 1g in die des anderen Schenkels 23 gebogen, - da ja die Mittelebenen der beiden Schenkel den über- bzw. untereinanderliegenden Zwingenarmen entsprechend nicht in einer Ebene liegen. Die Höhenlage der beiden Laschenschenkel gegeneinander sowie die Form der Versteifungsrippe 3o lassen besonders deutlich Abb. 3 und q. erkennen.As illustrated in Fig. 2, the double flap is designed so that the flap legs 1g and 23 lie outward from the point of intersection of the arms 12 and 16 or 13 and 15 and are connected to one another by a stiffening rib 30. This rib is bent out of the center plane of one leg 1g into that of the other leg 23, - since the center planes of the two legs do not lie in one plane corresponding to the clamp arms lying above or below one another. The height of the two flap legs relative to one another and the shape of the stiffening rib 3o are particularly clear in Fig. 3 and q. recognize.
Bei der dargestellten Ausführung ist der Schenkel 1g an der äußeren Langseite vollständig offen, so daß er auch seitlich auf den ihm zugehörigen Zwingenarm aufgeschoben und deshalb die ganze Doppellasche auch dann auf die Arme aufgebracht werden kann, wenn diese bereits im wesentlichen in die Lage gebracht sind, in welcher sie die Formbretter 1i zusammenhalten.In the embodiment shown, the leg 1g is on the outer side Long side completely open, so that it is also laterally on the clamp arm belonging to it pushed open and therefore the whole double flap is also applied to the arms can be, if these are already essentially brought into the position in which they hold the molding boards 1i together.
