Description

Bewehrung von Betonkonstruktionen Reinforcement of concrete structures
Die Erfindung betrifft eine Bewehrung von Betonkonstruktionen insbesondere im Brückenbau nach dem Oberbegriff des Anspruches 1.The invention relates to a reinforcement of concrete structures, in particular in bridge construction according to the preamble of claim 1.
Die bisher übliche Bauweise besteht darin, dass Litzenzugglieder in Hüllrohre verlegt und vorgespannt werden, wobei zum Korrosionsschutz die Rohre nachträglich mit Zement ausgepresst werden. Des Weiteren werden Spannglieder aus Monolitzen verwendet, wobei die Monolitzen bereits im Werk mit einem Korrosionsschutz aus Fett und Kunststoff versehen werden. Dabei werden die Monolitzen, wie z.B. in Fig. 1 gezeigt, als Einzelelemente verlegt. Des Weiteren können sie, wie in Fig. 2 gezeigt, zu einem Band zusam- mengefasst verlegt werden, und bei größeren Spanngliedern können sie nach Fig. 3 als Bänder mit einem Abstand von etwa 40 mm verlegt werden. Der Nachteil dieser Bauweise besteht darin, dass beim Verlegen der Monolitzen in Abständen voneinander gemäß Fig. 1 oder bei reihenweisem Verlegen nach Fig. 3 zwischen den Monolitzen bzw. den Reihen der Monolitzen Hohlräume bzw. tote Räume vorhanden waren, welche als Verlust gegolten haben.The hitherto customary construction is that Litzenzugglieder be laid in ducts and biased, the corrosion protection, the pipes are subsequently pressed out with cement. In addition, tendons made of monostrands are used, whereby the monostrands are provided already in the factory with a corrosion protection of grease and plastic. The monostrands, e.g. shown in Fig. 1, laid as single elements. Furthermore, as shown in FIG. 2, they can be laid down to form a band, and in the case of larger tendons they can be laid according to FIG. 3 as bands with a spacing of about 40 mm. The disadvantage of this design is that when laying the monostrands at intervals from each other as shown in FIG. 1 or in rows laying according to Fig. 3 between the monolayers and the rows of monolayers cavities or dead spaces were present, which have been considered as loss.
Eine Bewehrung der eingangs erwähnten Art ist durch die AT 4 023 Ul bekannt geworden und entspricht der Ausführungsform der Bewehrung nach Fig. 4.A reinforcement of the type mentioned above has become known from AT 4 023 Ul and corresponds to the embodiment of the reinforcement of FIG. 4th
Durch die EP 1 164 232 A2 ist bekannt geworden, Spannglieder als Bündel von einer Kunststoffhülle einzuschließen. Bei dieser Ausführungsform sind die Spannglieder des Bündels untereinander nicht verbunden. Diese Art der Bewehrung verfolgt einen anderen Zweck als die vorliegende Erfindung.From EP 1 164 232 A2 it has become known to include tendons as bundles of a plastic envelope. In this embodiment, the tendons of the bundle are not interconnected. This type of reinforcement has a different purpose than the present invention.
_Aufgabe der- -vorliegenden -Erfindung rsf, den Εereich dieser toten Räume noch weiter zu vermindern.The object of the present invention is to further reduce the area of these dead spaces.
Diese Aufgabe wird durch die Maßnahme nach dem kennzeichnenden Teil des Patentanspruches 1 gelöst.This object is achieved by the measure according to the characterizing part of claim 1.
Nach einem weiteren Merkmal der Erfindung sind die ummantelten Spannglieder bzw. Monolitzen um einen halben Durchmesser zuein- ander versetzt angeordnet, wodurch praktisch die weiteste Verdichtung der Lagen der ummantelten Spannglieder bzw. Monolitzen erzielt wird.According to a further feature of the invention, the sheathed tendons or monostrands are half a diameter in diameter. arranged staggered, which practically the widest compression of the layers of the sheathed tendons or monolayers is achieved.
Nach einem weiteren Merkmal der Erfindung können die ummantelten Spannglieder bzw. Monolitzen in einem Rohr verlegt werden* wodurch der Vorteil besteht, dass die ummantelten Spannglieder bzw. Monolitzen jederzeit aus dem Rohr herausgezogen werden können und man die Qualität des Korrosionsschutzes immer wieder kontrollieren kann.According to a further feature of the invention, the sheathed tendons or monolayers can be laid in a tube * which has the advantage that the sheathed tendons or monolayers can be pulled out of the tube at any time and you can check the quality of corrosion protection again and again.
Weitere Merkmale der Erfindung werden an Hand der Fig. 5 und 6 erläutert .Further features of the invention will be explained with reference to FIGS. 5 and 6.
Für den erfindungsgemäßen Verband werden die ummantelten Spannglieder 2 zu Bändern nach Fig. 2 untereinander verklebt bzw. verschweißt.For the dressing according to the invention, the sheathed tendons 2 are glued or welded together to form ribbons according to FIG. 2.
Die Fig. 5 und 6 zeigen je eine versetzte Anordnung der ummantelten Spannglieder- bzw. Monolitzenreihen um einen halben Durchmesser der Spannglieder bzw Monolitzen.5 and 6 each show an offset arrangement of the sheathed tendon or monoline rows by half the diameter of the tendons or monostrands.
Es wurde festgestellt, dass je dichter der Verband der Lagen der ummantelten Spannglieder bzw. Monolitzen ist, die Baukosten um so geringer im Hochbau für die Herstellung von Brücken der beschriebenen Bauart sind.It has been found that the denser the association of the layers of the sheathed tendons or monostrands, the construction costs are the lower in structural engineering for the production of bridges of the type described.
Eine dichte Bauart ergibt sich bereits bei einem Verband, bei welchem die Mittelpunkte 1 der ummantelten Spannglieder bzw. Monolitzen 2 einander versetzt angeordnet sind.A dense design already results in a dressing in which the centers 1 of the sheathed tendons or monolayers 2 are arranged offset from each other.
Um den toten Zwischenraum 6 zwischen den sich berührenden umman- _t,elten Spanngliede-r- bz-w-. -Monolithen "2'am 'weitesten zu verringern, ist nach einem weiteren Merkmal der Erfindung ein Verband nach Fig. 5 vorgesehen, bei welchem sich die Ummantelungen auf einer schrägen Linie 8 befinden, die zu der lotrechten Linie um einen Winkel von 45° verläuft. Diese Ausführungsform zeigt den dichtesten Verband der ummantelten Spannglieder.To the dead space 6 between the touching umman- _t, elten tendgliede-r- bz-w-. Monoliths "2 'am' to reduce furthest, there is provided a dressing according to FIG. 5, according to a further feature of the invention, in which the sheaths are located on an oblique line 8, which extends to the vertical line by an angle of 45 ° This embodiment shows the densest bond of the sheathed tendons.
Es besteht auch die Möglichkeit, die ummantelten Spannglieder 2 bzw. Monolitzen in ein weiteres Rohr 7 zu verlegen, wie beispielsweise die Fig. 6 zeigt. It is also possible, the sheathed tendons. 2 or to lay monolitzen in another tube 7, such as the Fig. 6 shows.
