Die Erfindung bezieht sich auf eine Stahlbeton-Bewehrung für hochbeanspruchte Baukörper, z.B. Tunnelgewölbe, bei der die Bewehrungsstähle lagenweise angeordnet und die vorgefertigten Lagen nach Erhärten des Betons schubfest miteinander verbunden sind.The invention relates to reinforced concrete reinforcement for highly stressed structures, e.g. tunnel vaults, in which the reinforcing steel is arranged in layers and the prefabricated layers are shear-proof after the concrete has hardened are connected to each other.
Bekannte Bewehrungen dieser Art leiden unter dem Mangel, daß sie lediglich in einer einzigen Ebene, entweder einer geraden Ebene oder einer gebogenen Ebene, verlegt werden können. Eine Verlegung in einer räumlich gekrümmten Ebene, z.B. in einer Kuppel, ist nicht möglich. Der Grund dafür liegt darin, daß zum mindesten eine Lage bei den bekannten Bewehrungen mit den übrigen Lagen fest verbunden ist.Well-known reinforcements of this type suffer from this Lack that they are only in a single plane, either a straight plane or a curved plane, can be laid. A laying in a spatially curved Level, e.g. in a dome, is not possible. The reason for this is that at least one location in the known reinforcement is firmly connected to the other layers.
Der Erfindung liegt die Aufgabe zugrunde, die Lagen der Bewehrung so zueinander anzuordnen, daß eine Verlegung der Bewehrung auch in räumlich gekrümmten Ebenen möglich ist.The invention is based on the object of arranging the layers of the reinforcement in relation to one another so that laying reinforcement is also possible in spatially curved planes.
co Wach der Erfindung ist diese Aufgabe dadurch gelöst,According to the invention, this object is achieved by
^ daß alle Lagen während der Montage für sich allein verwin-0^ dungsfähig und zueinander lose angeordnet sind. Auf diese ο Weise ist während der Montage jede Freiheit der ^iegung ο nach allen Richtungen hin gewährleistet,^ That all of the layers during assembly to 0 for ^ dung and capable of mutually loosely arranged alone torsion. In this way ο every freedom of movement ο in all directions is guaranteed during assembly,

Bei einer anderen Ausführungsform der Erfindung ist die schubfeste Verbindung zwischen den Lagen bei erhärtetem Beton durch vorgefertigte gebogene Bewehrungsstähle ge-. bildet. Dabei können korbartig zusammengesetzte Bewehtungsstäbe oder auch bandartig gebogene Bewehrungsstäbe Verwendung finden.In another embodiment of the invention is the shear-proof connection between the layers of hardened concrete is made by prefabricated bent reinforcing steel. forms. Reinforcement bars that are composed in the manner of a basket or reinforcement bars that are bent in the manner of a strip can be used Find use.
Die erfindungsgemäßen Bewehrungen können allen Unregelmäßigkeiten im Tunnel oder in einer sonstigen Baustelle, die sich aus dem Ausbruch des Tunnels oder aus dem ' vorher eingebrachten vorläufigen Tunnelausbau ergeben, angepaßt werden.The reinforcements according to the invention can all irregularities in the tunnel or in another construction site, resulting from the excavation of the tunnel or from the preliminary tunnel lining, be adjusted.
