Description
Bez.: Verfahren zur Herstellung von ein- und mehrlagigen Bewehrungskörben in Betonbalken Die Erfindung betrifft ein Verfahren zur Herstellung von ein- und mehrlagigen Bewehrungskörben in Betonbalken.Description: Process for the production of single and multi-layer reinforcement cages in concrete beams The invention relates to a method for producing one and multi-layer reinforcement cages in concrete beams.
Es ist bekannt, in Betonbalken einzelne gerade oder gebogene Rundeisen mit Rundstahlbügel unter Verwendung von Rödeidraht zu Bewehrungskörben zu verbinden. Es ist auch bekannt, schmale Baustahl-Mattenstreifen in beispielweise gebogene Bügelkörbe aus gebogenen Baustahlmatten zu legen und zu verdrahten, wodurch eine Beschleunigung der Bewehrungsarbeit erreicht wird.It is known to use individual straight or curved round bars in concrete beams to be connected with round steel stirrups using Rödeidraht to form reinforcement cages. It is also known to use narrow strips of structural steel mat in curved hanger baskets, for example to lay out and wire up bent welded wire mesh, thereby accelerating the reinforcement work is achieved.
Bei den beiden Verfahren können auch zwei oder drei Rundstahl-Lagen bei Verwendung von Abstandhaltern erzielt werden.With the two methods, two or three round steel layers can also be used can be achieved when using spacers.
:',e e Erfindung will die Rundstahlbewehrung von Stahlsetonbalken weiter verbessern, und erreicht dies durch ein Verfahren, bei welchem Rundstähle in Gruppen auf rechtwinklig liegende Verte'ilerstäbe zu einer ebenen Matte geschweißt werden, danach werden die Verteilerdrähte schlangenartig so gebogen, daß die Rundstahlgruppen in einem vorgegebenen Abstand waagerecht übereinander liegen. Bei dieser Anordnung sind die Rundstäbe in jeder Richtung unverschieblich gehalten, und die amtlich vorgeschriebenen Abstände untereinander sind ohne zusätzlichen Maßnahmen eingehalten. Mit RUcksicht auf die Normungen im Mauerwerksbau orientiert sich die Breite der horizontalen Schlangenlihienschenkel an den Mauerwerksstärken. Zur Erzielung gleichmäßiger Höhenabstände der Rundstahlgruppen wird in der ursprünglich ebenen Matte im Wechsel jeweils eine Rundstahlgruppe unter, und die folgende über die Verteilerstäbe geschweißt.: ', e invention wants the round steel reinforcement of steel seton beams further improve, and achieved this through a process in which round bars Welded in groups on right-angled distribution bars to form a flat mat after that the distributor wires so curved like a snake, that the round steel groups lie horizontally on top of each other at a predetermined distance. In this arrangement, the round bars are held immovable in every direction, and the officially prescribed distances between each other do not require any additional measures adhered to. Taking into account the standards in masonry construction, the Width of the horizontal serpentine line legs on the masonry thicknesses. To achieve uniform height spacing of the round steel groups is in the originally flat Mat alternately one round steel group under, and the following over the distributor bars welded.
Durch die schlangenartig übereinander gefalteten Rundstahlgruppen entsteht ein räumlich geordnetes Paket, dessen Breite, Höhe und Länge frei wählbar ist. Je nach den statischen und konstruktiven Erfordernissen werden einzelne Rundstahlgruppen abgetrennt und in die Bügelkörbe eingelegt.Through the serpentine groups of round steel bars the result is a spatially organized package whose width, height and length can be freely selected is. Depending on the static and structural requirements, individual round steel groups are used separated and placed in the hanger baskets.
Weitere Merkmale und Einzelheiten der Erfindung der durch dieselbe erzielten Vorteile ergeben sich aus der nachstehenden Beschreibung, von in der Zeichnung dargestellten Ausführungsbeispielen von Bewehrungsanordnungen zur Durchführung des erfindungsgemäßen Verfahrens.Further features and details of the invention are disclosed by the same The advantages achieved emerge from the following description of in the drawing illustrated embodiments of reinforcement arrangements for implementing the method according to the invention.
Fig.1 zeigt das räumlich geordnete Paket der übereinander gefalteten Rundstahlgruppen in der Ansicht und im Schnitt.Fig.1 shows the spatially ordered package of the folded one on top of the other Round steel groups in the view and in section.
Fig. 2 stellt einen Stahlbeton-Unterzug mit einer aus dem Paket Fig. 1 abgetrennten Rundstahlgruppe dar. Die Bügelbewehrung ist hierbei nicht gezeichnet.Fig. 2 shows a reinforced concrete beam with one from the package Fig. 1 separate round steel group. The stirrup reinforcement is not shown here.
Fig. 3 zeigt zwei übereinander liegende Rundstahlgruppen.Fig. 3 shows two groups of round steel bars lying one above the other.
Fig. 4 zeigt drei übereinander liegende Rundstahlgruppen.4 shows three groups of round steel bars lying one above the other.
Fig. 5 stellt die erfindungsemäße Anordnung dar, wenn die obere Rundstahlgruppe zur Aufnahme größerer Schubkräfte aufgebogen ist.Fig. 5 shows the inventive arrangement when the upper round steel group is bent up to absorb greater shear forces.
Fig. 6 demonstriert die Anordnung-, wenn bei drei Rundstahlgruppen dia oberen zwei in Anpassung an den Schubverlauf aufgebogen sind.Fig. 6 demonstrates the arrangement - if there are three groups of round steel bars the upper two are bent up to match the thrust course.
Fig. 7 zeigt schließlich die Anordnung über einer Hittelstütze.7 finally shows the arrangement above a central support.
Insbesondere bei den erfindungsgemäßen Anordnungen nach Abb. 3 - 7 ergeben sich Vorteile, weil den statischen Erfordernissen angepaßte Bewehrungselemente, aus geraden und aufgebogenen Stabgruppen, konstruiert werden können, die durch die schlangenartig gebogenen Verteilerstäbe im mittleren parallelen Bereich zu einem Ganzen verbunden bleiben Das Verfahren gestattet aber auch die Aufbiegung einzelner Stäbe, beispielsweise, wenn nur eine. Stabgruppe vorhanden ist.In particular with the arrangements according to the invention according to FIGS. 3-7 there are advantages because reinforcement elements adapted to the static requirements, can be constructed from straight and bent groups of rods, which by the serpentine curved distribution rods in the central area parallel to one Remaining connected as a whole The process also allows individual ones to be bent open Rods, for example, if only one. Member group exists.
Die Anpassung an den statisch erforderlichen Stahlquerschnitt erfolgt durch Anordnung einer, zweier oder dreier Stabgruppen, oder durch Kombinieren mit Stabgruppen anderer - Stabdurchmesser.The adjustment to the statically required steel cross-section takes place by arranging one, two or three groups of bars, or by combining them with Bar groups of others - bar diameter.
Wenn wegen der unterschiedlichen Länge der Unterzüge Reste im Bewehrungspaket Abb 1 entstehen, so werden diese für Tür- und kleine Fensterstürze verwendet.If there are remains in the reinforcement package because of the different lengths of the beams Fig. 1 arise, so these are used for door and small window lintels.
Bei der Durchführung des Verfahrens können die Rödelarbeiten mit Bindedraht ganz entfallen.When carrying out the process, the tying work can be done with binding wire completely omitted.
