Description
Die Erfindung betrifft ein Schaluugselem@ent zum Herstellen von Betondecken unter Verwendung von Fertigträgern. Bei ,der Herstellung solcher Diecken werden die Zwischenräume zwischen den Trägern häu%g in der Weise mit Beton ;ausgefüllt" da.ß zwischen diesen Trägern besondere gewölbte Schalungsblecheeingebracht werden. Bei feinem. solchen Verfahren ist vorgesehen, daß die Gewölbieschalungselem,ente, welche die Zwischenräume zwischen den Trägern überbrücken, unmittelbar auf die Deckenträger aufgelegt werden und daß ihre Schenkel so weist beweglich sind, daß @ nach dem Abbinden des Dieckenbetons die Schalungselemente durch Zusammenbiegen ,der Schenkel und durch leinte S chwe'nkhewegung um ihre reine Auflagekante aus dein Zwischenraum ,entfernt werden könnten.The invention relates to a Schaluugselem @ ent for producing concrete ceilings using prefabricated beams. At, the manufacture of such a die will be the spaces between the girders are often filled with concrete like this " da.ß special arched shuttering sheets are introduced between these beams. With fine. such method is provided that the vaulted formwork elements, duck, which bridge the gaps between the girders, directly onto the ceiling girders be placed and that their legs are movable so that @ after setting dieckenbetons the formwork elements by bending together, the legs and through Leashed swivel walk around its pure support edge from your space, removed could become.
Um solche Elemente auch für unterschiedliche Trägerabstände verwendbar zu machen, ist gemäß der Erfindung vorgesehen, daß die Auflagerenden der Schalungseliernente, unter gleichzeitiger Vergrößerung der Gewölbehöhe, in siolch,em, Maße gegeneinander beweglich sind, daß ein und dasselbe Element für verschiedene Trägerabstände verwendbar ist.Around such elements can also be used for different carrier spacings to make, it is provided according to the invention that the support ends of the formwork elements, with a simultaneous increase in the height of the vault, in siolch, em, dimensions against each other are movable that one and the same element can be used for different carrier distances is.
Zweckmäßig ist res, ,die Schalungselemente so auszubilden, daß die S:chalungsschenkel gegeneinander bewegbar sind. Brei starren Schalungen kann dies z. B. durch gelenkige Anbringung der Schenkel geschehen; biet -der Herstellung der Schalungselemienbe ,aus Blech lassen sich bierentsprechender Blechstärke jedoch die Schenkelenden unter elastischer Verformung -der Schalungsielemente und Vergrößerung ihrer Bogenhöhe so biegen, ,daß ein tmd dasselbe Element für verschiedene Trägerabstände verwendbar ist. Eine; besonders günstige Ausführungsform ,der Erfindung ist in der Zeichnung schematisch wiedergegeben. In ihr zeigt Fig. i ,den Querschnitt der Träger und der ,darauf aufgesetzten Suhalungsbleche, Fig. 2 ,denselben Schnitt nach Einfüllen des Dieckenbetons, Fig.3 nochmals ,den gleichen Querschnitt ,nach dein, Abbinden des Dieckenbetons im Augenblick des Entfernens :einfies Schalungs,elem,entes durch Einwärtsbiiegen des :einen Schenkels und Abwärtsschwenken der Schalung um die Auflagekante des anderen.It is useful res, to form the formwork elements so that the S: chalung legs are movable against each other. Pulp rigid formwork can do this z. B. done by articulated attachment of the legs; offer the production of Formwork elements made of sheet metal, however, can be made of sheet metal thickness that corresponds to beer the leg ends under elastic deformation -the formwork elements and enlargement Bend their arch height so that one tmd the same element for different beam distances is usable. One; particularly favorable embodiment, the invention is in the Drawing shown schematically. In it Fig. I shows the cross section of the carrier and the Suhalungsbleche placed thereon, Fig. 2, the same section after filling of the diecken concrete, Fig. 3 again, the same cross-section, after you have set the diecken concrete at the moment of removal: Einfies formwork, elem, duck through Inward bending of the: one leg and downward pivoting of the formwork around the support edge of the other.
In ,dem Ausführungsbeispiel sind Träger dargestellt, bei denen nur der Trägerfuß i mit den, Zugeisen 2 in Bieton vorgeformt ist, während die übrige Trägerbewehrung mit dem Druckeisen 3 und den Strebten 4 noch frei liegt. Zwischen je zwei. solchen Trägerfüßen i ist ein gewölbtes S.chalungsbl,ech 5 ,eingesetzt, dessen Auflagekanten bei 51 zweifach winkelförmig abgekantet ,sind, damit fier eine Schenkel .der Abkantung satt auf der Obersieitd des Trägerfußes i aufliegt, während der anderq Schenkel an ,der Seitenfläche der Trägerfüße i anliegt, um ein weiteres Aufspreizen des elastischen, Schalungsielementes zu verhindern. In den an der Seitenfläche der Träger i anliegenden Schenkeln der Abkröpfungen 51 sind dabei in gewissen Abständen Ausbuchtungen 52 vorgesehen (Fig. 2), in welche ein Hebeleisen beingesteckt werden kann, um den Schalungsschenkel .so weit einwärts zu biegen, ,daß ier, wie in Fig. 3 gezeigt, an ,dem Trägerfuß vorbei nach abwärts geschwenkt werden kann. An Stelle der Ausbuchtungen 52 könnten auch beliebige andere Ansätze, wie ösien usw., am S:cbalungs,blech angebracht stein, die res gestatten, mit irgendwelchen Werkzeugen die Sachenkel der Gewölbeschalung ,einander so weit elastisch zu nähern, daß nach dem Abbinden des Betons die Schalung aus. ,dem Zwischenraum zwischen den Trägern entfernt werden kann.In, the embodiment, carriers are shown in which only the support foot i is preformed with the pull bar 2 in bid clay, while the rest Beam reinforcement with the pressure iron 3 and the struts 4 is still exposed. Between two each. such girder feet i an arched formwork bl, ech 5, is used, the support edges of which at 51 are bent twice at an angle, thus fier one Leg .der the fold rests fully on the Obersieitd of the support foot i, while the other leg on, the side surface of the support feet i rests to another To prevent spreading of the elastic, formwork element. In the one on the side face the legs of the bends 51 resting against the carrier i are at certain intervals Bulges 52 are provided (FIG. 2) into which a pry bar can be inserted can to bend the formwork leg inward so far that it, as shown in Fig. 3, the carrier foot can be pivoted downward past. Instead of of the bulges 52 could also be any other desired approaches, such as ösien, etc., on the bellows, sheet metal attached stone, the res allow, with any tools, the object legs the vault formwork to approach each other so elastically that after setting the concrete from the formwork. , the space between the beams must be removed can.
Die biesehriebene Ausführungsform ,der Erfindung mit biegsamen Einsahalungselernenten ist nun in der Weisse anzuwenden, daß ein und dasselbe Elemient für unterschiedliche Trägerabstände verwendet wird. Jte näher die Träger an,einandergerückt sind, desto höher wölbt sich die Schalung und desto stärker wird biet igleichbleibender Überdeckung der Schalung mit Beton,die Drecke.The two-level embodiment of the invention with flexible enclosure elements is now to be applied in the white that one and the same element for different Beam spacing is used. The closer the carriers are, the closer they are to one another The higher the formwork arches and the stronger the constant cover becomes the formwork with concrete, the dirt.
