Description

Characteristic of the known state of the art

Im Hoch- und Tiefbau werden Bewehrungskörbe für den Betonbau in der Weise hergestellt, daß die Sewehrungsbügel einzeln maschinell gebogen werden, in entsprechender Anzahl zueinander manuell ausgerichtet und an jeder Stelle, an denen sich die Bewehrungsbügel mit den statischen Betonstahlprofilen kreuzen bzw. berühren mit diesen durch Verdrahten verbunden werden.In building and civil engineering reinforcing baskets are made for concrete construction in such a way that the reinforcing bars are bent individually by machine, aligned manually in a corresponding number and at each point where the reinforcing bars with the static reinforcing steel profiles intersect or touch with this through Wiring be connected.

Das Fertigen der bekannten Bewehrungskörbe erfolgt im allgemeinen an den Baustellen, da sie für den Transport wegen der Verdrahtung der Bewehrungsbügel mit den statischen Betonstrahlprofilen zu instabil sind. Die Bewehrungskörbe werden nach dem Ausrichten auf der Baustelle zu dem fertigen Bauwerk in Beton eingegossen.The manufacturing of the known reinforcement baskets is generally carried out on the construction sites, as they are too unstable for transport because of the wiring of the reinforcing bar with the static concrete beam profiles. The reinforcement baskets are poured into the concrete after alignment at the construction site to the finished structure.

Dieses manuelle Fertigen der Bewehrungskörbe führt jedoch zu schwerwiegenden Nachteilen:However, this manual fabrication of the reinforcement cages leads to serious disadvantages:

Trotz großer Sorgfalt bei der manuellen Fertigung ist der Streubereich der Maßhaltigkeit sehr groß.Despite great care in manual production, the range of dimensional accuracy is very large.

Ungenauigkeiten treten bereits auf bei der Fertigung der einzelnen Bewehrungsbügel.Inaccuracies already occur during the production of the individual reinforcing bars.

Ungenauigkeiten treten weiterhin auf bei der Montage der Bewehrungsbügel und der statischen Betonstahlprofile zu den Bewehrungskörben.Inaccuracies continue to occur during assembly of the reinforcing bars and the static reinforcing steel profiles to the reinforcement cages.

Ungenauigkeiten treten zusätzlich auf bei Montage der Bewehrungskörbe in die Bewehrungssysteme.Inaccuracies also occur when mounting the reinforcement cages in the reinforcement systems.

Die Folgen sind, daß die vorgegebenen Betondeckungen ium Teil unter- bzw. überschritten werden und daß der rechnerische statische Querschnitt im allgemeinen an den verschiedenen Stellen unterschiedlich ist. Außerdem ist die Transportfähigkeit sehr begrenzt, daher ist eine Vormontage in geschlossenen Räumen fast unmöglich, so daß eine Fertigung in Schlechtwetterperioden ausfällt.The consequences are that the specified concrete coverings are in some cases under- or exceeded, and that the computational static cross section is generally different at the various points. In addition, the transportability is very limited, therefore, a pre-assembly in closed spaces is almost impossible, so that production fails in bad weather periods.

Der manuell gefertigte Korb ist sein instabil, da die Bewehrungsbügel mit den statischen Betonstahlprofilen verdrahtet sind. Es können deshalb Fehler durch unsachgemäßes Betonieren oder durch unsachgemäßen Umgang des Personals mit den Bewehrungskörben auftreten.The manually made basket is unstable because the reinforcing bars are wired to the static reinforcing steel profiles. Therefore, mistakes may occur due to improper concreting or improper handling of the personnel with the reinforcement baskets.

Die Folge ist, daß nach dem Vergießen des Betons der geforderte Betondeckungsabstand oft unterschritten wird, so daß Feuchtigkeit zu den Bewehrungsbügeln diffundieren kann und bei Kälteeinwirkung ein Abplatzen des Betons im Bereich der unterschrittenen Betondeckung vorkommt. Diese freiliegenden Abschnitte der Bewehrungsbügel lösen das Durchrosten des freiliegenden Bewehrungssystems aus, so daß die statische Tragfähigkeit dieser Bauwerke in Frage gestellt bzw. dann nicht mehr gegeben ist.The result is that after pouring the concrete, the required concrete cover distance is often below, so that moisture can diffuse to the reinforcing brackets and chipping occurs when exposed to cold concrete in the range of undercutting concrete cover. These exposed portions of the reinforcing bars trigger the rust through the exposed reinforcement system, so that the static load capacity of these structures in question or is no longer given.

Die aufwendigen und umfassenden Sanierungsmaßnahmen zeigen, daß man diese Probleme trotz der jahrzehntelangen Erfahrungen mit bewehrtem Beton bis heute noch nicht in den Griff bekommen hat.The complex and comprehensive remediation measures show that these problems have not been resolved to this day, despite decades of experience with reinforced concrete.

Die Montage der Bewehrungsbügel und der statischen Betonstahlprofile zu den Bewehrungskörben ist eine höchst lohnintensive und damit kostenaufwendige Arbeit.The installation of the reinforcing bars and the static reinforcing steel profiles to the reinforcement baskets is a highly labor-intensive and therefore costly work.

Weiterhin erfordern bereits die Ungenauigkeiten bei der Fertigung und bei der Montage einen erheblichen Sicherheitszuschlag.Furthermore, already require the inaccuracies in manufacturing and assembly a significant safety margin.

Ein weiterer Nachteil besteht darin, daß es aufgrund der Drahtverbindungen zwischen den Bewehrungsbügeln und den statischen Betonstahlprofilen kaum möglich ist, größere Bewehrungskörbe an Baustellen zu transportieren, da unter den Erschütterungen während des Transportes die Bewehrungsbügel untereinander und zu den statischen Betonstahlprofilen verkanten bzw. aus ihrer Lage gebracht werden und ein abschließendes zufriedenstellendes Richten auf der Baustelle vor dem Betonieren im allgemeinen nicht möglich ist.Another disadvantage is that it is hardly possible due to the wire connections between the reinforcing bars and the static reinforcing steel profiles to transport larger reinforcing baskets to construction sites, as under the vibrations during transport, the reinforcing bracket with each other and to the static reinforcing steel profiles tilt or out of their position be brought and a final satisfactory straightening on the site before concreting in general is not possible.

Object of the invention

Das Ziel der Erfindung besteht darin, einen Bewehrungskorb zur Verfügung zu stellen, der ökonomisch günstig ist, sowie ein Verfahren zum Herstellen des Bewehrungskorbes zur Verfügung zu stellen, mit welchem ökonomisch günstig und zuverlässig der Bewehrungskorb produziert werden kann.The object of the invention is to provide a reinforcing cage which is economically favorable as well as to provide a method for producing the reinforcing cage with which the reinforcing cage can be produced economically and reliably.

Darlegung des Wesens der ErfindungExplanation of the essence of the invention

De. Erfindung liegt die Aufgabe zugrunde, einen Bewehrungskorb zu schaffen, der maßhaltig ist, beim Betonieren die sichereDe. Invention is the object of the invention to provide a reinforcing cage that is dimensionally stable when concreting the safe

Due to the common centering and mounting profiles ensures that the reinforcement profiles of the finished 6ewehrungskorbes

zueinander ausgerichtet bzw. jntriert sind und bleiben und auch dem Modell des Statikers entsprechen, das dieser einenare aligned with each other and / or remain and also correspond to the model of the structural engineer, this one

Based on calculations. Through these measures is further achieved that the individual sections of the reinforcing bracket in defined levels

verlaufen und beim Betonieren der vorgegebene Mindestabstand der Betondeckung ohne weiteres eingehalten werden kann.run and when concreting the predetermined minimum distance of the concrete cover can be complied with easily.

Surprisingly, the centering and Montageprofilo and welded to them reinforcing bars form one

formstabilen Verbund, so daß es ohne weiteres möglich ist, die noch nicht mit den statischen Betonstahlprofilen verbundenenerfindungsgemäßen Bewehrungskörbe als vorgefertigte Baueinheiten zu den Baustellen zu transportieren und erst dort mitihnen zu verbinden. Dies ist insbesondere dann von Wichtigkeit, wenn die fertigen Bewehrungskörbe Abmessungen aufweisen,die ohne Sondergenehmigung nicht auf der Straße transportiert werden dürfen. Die vorgefertigten Baueinheiten könnenineinander geschachtelt platzsparend gelagert und platzsparend transportiert werden.dimensionally stable composite, so that it is readily possible to transport the invention not yet associated with the static reinforcing steel profiles inventive reinforcement cages as prefabricated units to the construction sites and only there to connect with them. This is particularly important if the finished reinforcement cages have dimensions that may not be transported on the street without special permission. The prefabricated units can be stored nested together to save space and transported in a space-saving manner.

In a further embodiment of the invention, the centering and mounting profiles outside the bending points with the Reinforcing bars welded. By these measures it is achieved that the bending performed accurately and easily

In yet another embodiment of the invention, the reinforcing bars are at predetermined locations with the static Reinforced steel profiles welded and / or wired. It turned out that it was without affecting the structural Safety is no longer necessary to connect the reinforcing bars at all points with the static reinforcing steel profiles. This is particularly the case when it is made by spot welding at the joints of the joint. It was found that even if the reinforcing cage according to the invention is not spot-welded at all points, he at Strains resumes its original shape or shape, provided that its elastic limit is not exceeded. In a still further embodiment of the invention, the mutual distances of the bracket correspond by the structural analysis
