Aus rechteckigen Faserbetonplatten bestehende verlorene SchalungLost formwork consisting of rectangular fibre concrete panels
Die Erfindung betrifft eine verlorene Schalung aus stoßend zu verlegenden rechteckigen Faserbetonplatten.The invention relates to a permanent formwork made of rectangular fiber-reinforced concrete panels that are to be laid end-to-end.
Bei der Erstellung von verlorenen Schalungen aus stoßend zu verlegenden, hochkant auf einer Unterlage aufsitzenden Faserbetonplatten bedarf es der Zusammenfassung der die Schalung ausbildenden Faserbetonplatten. Das geschieht bislang in recht primitiver Weise mit Hilfe von an den Faserbetonplatten stoßübergreifend anzusetzenden Klemmelementen, die nach dem Einbringen des Beton und/oder Estrichs wieder entfernt werden müssen.When creating permanent formwork from fiber-reinforced concrete panels that are to be laid end-to-end and sit upright on a base, the fiber-reinforced concrete panels that form the formwork must be joined together. This has so far been done in a rather primitive way using clamping elements that are attached to the fiber-reinforced concrete panels across the joints and that have to be removed again after the concrete and/or screed have been poured.
Ausgehend vom Stand der Technik liegt der Erfindung das Bedürfnis nach einer in einfacher Weise zu erstellenden dauerhaften Zusammenfassung von eine verlorene Schalung ausbildenden Faserbetonplatten zugrunde, die im Sinne der verlorenen Schalung dann auch nach dem Einbringen des Füllmaterials keiner Demontage mehr bedarf.Based on the state of the art, the invention is based on the need for a permanent combination of fiber-reinforced concrete panels that can be easily created and that form a permanent formwork, which, in the sense of the permanent formwork, no longer requires dismantling even after the filling material has been introduced.
Dem Bedürfnis wird mit einer aus hochkant auf einer Unterlage aufsitzenden, stoßend verlegten Faserbetonplatten bestehenden verlorenen Schalung mit folgenden Merkmalen Rechnung getragen:This need is met with a permanent formwork consisting of fiber-reinforced concrete panels that are laid vertically on a base and have the following features:
Faserbetonplatten mit einer in einer Flachseite der Platten, sich über die Länge derFibre-reinforced concrete panels with a flat side of the panels extending over the length of the
Platten erstreckend ausgebildeten hinterschnittenen NutPlates extending undercut groove
und sich in die Nut stoßüberbrückend form- und kraftschlüssig einfügende Federn,and springs that fit into the groove in a form-fitting and force-fitting manner,
die mit einem mittigen über die Faserbetonplatten vorspringenden Ansatz versehenwhich are provided with a central projection protruding over the fibre concrete slabs
sind.are.
Ausgestaltungen der Bestandteile der verlorenen Schalung, speziell der stoßende Faserbetonplatten zusammenfassenden Feder ergeben sich aus den Unteransprüchen 2 bis 5.Designs of the components of the permanent formwork, especially the spring that joins the abutting fiber concrete panels, are set out in subclaims 2 to 5.
Die die verlorene Schalung ausbildenden Faserbetonplatten, und zwar die aneinander angrenzenden Faserbetonplatten, werden hierbei durch die stoßüberbrückend in die in den Faserbetonplatten ausgebildeten Längsnuten die Faserbetonplatten lageorientiert zusammenfassend eingefügt, wobei die Flachseiten der Faserbetonplatten, in denen die die Federn aufnehmenden Längsnuten ausgebildet sind, die Innenseite der Schalung bilden. Der an den Federn ausgebildete, über die Faserbetonplatten vorspringende Ansatz an den Federn eröffnet die Möglichkeit, die Federn in den Längsnuten auch im nachhinein noch zur Erzielung einer hinreichenden Überdeckung des Stoßes zu verlagern. Die die Faserbetonplatten zusamamenfassenden Federn verbleiben einbetoniert an Ort und Stelle. Der aus den Platten vorspringende, an den Federn ausgebildete Ansatz wie auch die an der Innenseite der Faserbetonplatten ausgebildeten Längsnuten zur Aufnahme der Federn tragen dann auch in wünschenswerter Weise zur form- und stoffschlüssigen Zusammenfassung der die verlorene Schalung ausbildenden Faserbetonplatten mit dem eingebrachten Beton bei.The fiber concrete panels that form the permanent formwork, namely the fiber concrete panels that are adjacent to one another, are inserted in a position-oriented manner by bridging the joints in the longitudinal grooves formed in the fiber concrete panels, whereby the flat sides of the fiber concrete panels, in which the longitudinal grooves that accommodate the springs are formed, form the inside of the formwork. The projection on the springs that protrudes over the fiber concrete panels opens up the possibility of relocating the springs in the longitudinal grooves even later in order to achieve sufficient coverage of the joint. The springs that hold the fiber concrete panels together remain in place, set in concrete. The projection on the tongues protruding from the panels as well as the longitudinal grooves on the inside of the fiber-reinforced concrete panels to accommodate the tongues also contribute in a desirable way to the form-fitting and material-locking connection of the fiber-reinforced concrete panels forming the permanent formwork with the concrete that has been poured.

Die die verlorene Schalung ausbildenden Faserbetonplatten sind mit 11, 11' bezeichnet. In einer der Flachseiten der Faserbetonplatten 11, 11', nämlich der im verlegten Zustand die Innenseite der verlorenen Schalung ausbildenden Flachseite 111 ist eine sich über die Länge der Faserbetonplatten erstreckende Längsnut 112 ausgebildet.The fiber-reinforced concrete panels forming the permanent formwork are designated 11, 11'. In one of the flat sides of the fiber-reinforced concrete panels 11, 11', namely the flat side 111 forming the inside of the permanent formwork when laid, a longitudinal groove 112 extending over the length of the fiber-reinforced concrete panels is formed.
In die Längsnuten 112 der hochkant auf einer Unterlage 12 aufsitzenden, stoßend verlegten Faserbetonplatten 11, 11' (Fig. 3) wird eine Feder 16 stoßüberbrückend form- und kraftschlüssig eingefügt, wobei ein an der Feder 16 ausgebildeter Ansatz 161 aus der Plattenoberfläche 111 vorspringt (Fig. 4). Die Feder 16 erbringt die erforderliche Lageorientierung der die verlorene Schalung ausbildenden Faserbetonplatten 11,1&Ggr;... Der an der Feder 16 ausgebildete Ansatz 161 eröffnet noch nach dem Aufstellen der die verlorene Schalung bildenden Faserbetonplatten 11,1&Ggr;... eine Verlagerung der Federn 16 in den in den Faserbetonplatten 11,1&Ggr;... ausgebildeten Nuten 112, wenn sich das für eine hinreichende Überdeckung des Stoßbereichs (116) der stoßenden Faserbetonplatten 11, 1&Ggr;... als erforderlich erweisen sollte. Zur Erleichterung des Einfügens der Federn 16 in die in den Faserbetonplatten 11, 11'... ausgebildeten Längsnuten 112 erweist sich die Verwendung von sich an ihren Enden 162, 162' verjüngenden Federn 16 als zweckmäßig. Als zweckmäßig erweist sich dann auch eine eine Querschnittsreduzierung der Federn 16 ermöglichende Längsschlitzung 163 der Federn an deren Rückseite, womit sich Verarbeitungstoleranzen in den in den Faserbetonplatten 11.11'... ausgebildeten Längsnuten 112 überbrücken lassen.A spring 16 is inserted in a form-fitting and force-fitting manner into the longitudinal grooves 112 of the fiber-reinforced concrete panels 11, 11' (Fig. 3) that are laid edgewise on a base 12, bridging the joints, with a projection 161 formed on the spring 16 projecting from the panel surface 111 (Fig. 4). The spring 16 provides the required positional orientation of the fiber concrete panels 11,1&Ggr;... forming the permanent formwork. The projection 161 formed on the spring 16 allows for a displacement of the springs 16 in the grooves 112 formed in the fiber concrete panels 11,1&Ggr;... even after the fiber concrete panels 11,1&Ggr;... forming the permanent formwork have been set up, if this should prove necessary for sufficient coverage of the joint area (116) of the jointed fiber concrete panels 11, 1&Ggr;... To facilitate the insertion of the springs 16 into the longitudinal grooves 112 formed in the fiber concrete panels 11, 11'..., the use of springs 16 that taper at their ends 162, 162' proves to be expedient. It also proves to be useful to have longitudinal slots 163 on the back of the springs 16, which allow a reduction in the cross-section of the springs 16, whereby processing tolerances in the longitudinal grooves 112 formed in the fiber-reinforced concrete panels 11.11'... can be bridged.
Die die Faserbetonplatten 11, 11'... zusammenfassenden Federn 16 können aus einem geeigneten Kunststoff bestehen, dabei kann es sich dann auch um ein Blechformteil handeln.The springs 16 that hold the fiber-reinforced concrete panels 11, 11'... together can be made of a suitable plastic, and can also be a molded sheet metal part.
Aus fertigungstechnischen Gründen wird die in den Faserbetonplatten vorzusehende Längsnut in der Regel durchgängig, also sich über die Länge der Platten erstreckend ausgebildet werden, das schließt sich von den Stirnseiten der Platten ausgehend begrenzt in die Platten hinein erstreckende Längsnuten nicht aus.For manufacturing reasons, the longitudinal groove to be provided in the fiber-reinforced concrete panels is generally designed to be continuous, i.e. to extend over the length of the panels. This does not exclude longitudinal grooves extending into the panels starting from the front sides of the panels.
