Abstract

Shear reinforcement is provided in the area of zones subject to shear force stress for increasing their support ability. The form of the thrust reinforcement component runs approximately like a screw line, the longitudinal axis of which runs at least approximately horizontally. The shear reinforcement components (1) are supported and/or fixed on the upper and/or lower bending reinforcement (4,7). The shear reinforcement components are of steel, preferably building steel. The shear reinforcement components, when viewed in the direction of their longitudinal axis, have straight line, and vertically extending side sections (9,10), of which two successive sections are joined to each other on the lower and upper ends by an arc-shaped section (11,12).

Description

Die Erfindung betrifft eine Bewehrung aus mindestens einer oberen und/oder unteren horizontalen Biegebewehrung und Schubbewehrungselementen für auf Stützen aufgelagerte Flachdecken aus Stahl- oder Spannbeton, welche zur Erhöhung der Tragfähigkeit querkraftbeanspruchter Zonen, insbesondere durchstanzgefährdeter Zonen, im Bereich dieser Zonen den Erfordernissen der Schubdeckung entsprechend mit im Innern der Flachdecke sich erstreckenden Schubbewehrungselementen versehen ist, ein Schubbewehrungselement für eine solche Schubbewehrung, sowie ein Verfahren zur Herstellung einer solchen Bewehrung.The invention relates to a reinforcement consisting of at least one upper and / or lower horizontal bending reinforcement and shear reinforcement elements for flat slabs made of reinforced or prestressed concrete supported on supports which, in order to increase the load-bearing capacity of zones subjected to shear forces, in particular zones prone to punching, meet the requirements of shear coverage in the area of these zones is provided in the interior of the flat slab extending shear reinforcement elements, a shear reinforcement element for such shear reinforcement, and a method for producing such reinforcement.

Es ist bereits bekannt, in Zonen der vorangehend erwähnten durchstanzgefährdeten Art Gruppen von mindestens annähernd senkrecht zur Deckenfläche verlaufenden, im Innern der Flachdecke sich erstreckenden Schubbewehrungsstäben vorzusehen, wobei die letzteren an ihren oberen und unteren Enden mit je einem sich verdickenden Kopf versehen, und zur Bildung von Schubbewehrungselementen gruppenweise über je einen Distanzhalter fest miteinander verbunden sind.It is already known to provide groups of shear reinforcing bars extending at least approximately perpendicular to the ceiling surface and extending in the interior of the flat ceiling in zones of the above-mentioned type of punching, the latter providing a thickening head at their upper and lower ends, and for formation of shear reinforcement elements are firmly connected to each other in groups via a spacer.

Solche Schubbewehrungselemente weisen den Nachteil auf, daß sie bei einer Ausbildung für den Einsatz im unteren Lastbereich fast gleich teuer in der Herstellung kommen, wie bei einer Ausbildung für den Einsatz im oberen Lastbereich, und daß ihre Schubbewehrungsstabdichte nach der Herstellung dieser Elemente nicht mehr veränderbar ist.Such shear reinforcement elements have the disadvantage that they are almost as expensive to manufacture if they are designed for use in the lower load range as if they are designed for use in the upper load range, and that their shear reinforcement bar density cannot be changed after the manufacture of these elements .

Aufgabe der vorliegenden Erfindung ist die Schaffung einer Bewehrung deren insbesondere für den unteren Lastbereich bestimmte Schubbewehrungselemente sehr einfach und kostengünstig, z.B. ab einer Draht- oder Bandrolle, kontinuierlich herstellbar und nach deren Herstellung auf einfache Weise durch Veränderung des Windungsabstandes bzw. der Schraubenliniensteigung an deren Einsatz in unterschiedlichen Lastbereichen anpassbar sind.The object of the present invention is to create a reinforcement whose shear reinforcement elements, in particular for the lower load range, are very simple and inexpensive, e.g. from a wire or tape reel, continuously producible and after their production can be easily adapted to their use in different load ranges by changing the winding spacing or the helix pitch.

Diese Aufgabe wird erfindungsgemäss nach Anspruch 1 gelöst.According to the invention, this object is achieved according to claim 1.

Zweckmäßige Weiterausgestaltungen der erfindungsgemässen Bewehrung sind Gegenstand der Ansprüche 2 bis 4.Advantageous further developments of the reinforcement according to the invention are the subject of claims 2 to 4.

Gegenstand der vorliegenden Erfindung ist ferner ein Schubbewehrungselement zum Einsetzen in eine Biegebewehrung, sowie ein Verfahren zur Herstellung einer Bewehrung nach Anspruch 1 mittels Schubbewehrungselementen nach Anspruch 5.The present invention furthermore relates to a shear reinforcement element for insertion into a bending reinforcement, and to a method for producing a reinforcement according to claim 1 by means of shear reinforcement elements according to claim 5.

Nachstehend wird die Erfindung anhand der Zeichnung beispielsweise erläutert. Es zeigen:

  • Fig.1 und 2 in Seitenansicht je eine beispielsweise Ausführungsform eines erfindungsgemässen Schubbewehrungselementes;
  • Fig. 3,4 und 5 im Grundriß beispielsweise Anordnungen von erfindungsgemässen Schubbewehrungselementen in auf Stützen aufgelagerten Flachdecken;
  • Fig.6 bis 14 im Grundriß, in Seiten- sowie in Stirnansicht drei weitere beispielsweise Ausführungsformen von erfindungsgemässen Schubbewehrungselementen.
The invention is explained below with reference to the drawing, for example. Show it:
  • 1 and 2 in side view each an example embodiment of a shear reinforcement element according to the invention;
  • 3, 4 and 5 in plan, for example, arrangements of shear reinforcement elements according to the invention in flat slabs supported on supports;
  • 6 to 14 in plan, in side and in front view three further examples of embodiments of shear reinforcement elements according to the invention.

In Fig. 1 ist in Seitenansicht eine aus Rundmaterial (Stahl) und in Figur 2 eine aus Flachstahl hergestellte Ausführungsform eines Schubbewehrungselementes 1 dargestellt. Die aus Flachstahl hergestellte Ausführungsform weist in einbetoniertem Zustand den Vorteil einer breiteren Abstützfläche im sie umgebenden Beton auf.1 shows a side view of an embodiment of a shear reinforcement element 1 made of round material (steel) and in FIG. 2 an embodiment made of flat steel. The embodiment made of flat steel has the advantage of a wider supporting surface in the concrete surrounding it when it is concreted in.

Bei den in den Figuren 3,4 und 5 im Grundriß dargestellten, auf Stützen 2 aufgelagerten, aus Stahl- oder Spannbeton hergestellten Flachdecken 3 sind zur Erhöhung der Tragfähigkeit querkraftbeanspruchter Zonen, insbesondere durchstanzgefährdeter Zonen, im Bereich dieser Zonen den Erfordernissen der Schubdeckung entsprechend im Innern der Flachdecke 3 angeordnete Schubbewehrungselemente 1 vorgesehen, die z.B. mittels Befestigungsdrähten an der Unterseite der oberen horizontalen Biegebewehrung 4 entsprechend befestigt sind.In the plan shown in FIGS. 3, 4 and 5, supported on supports 2 and made of reinforced or prestressed concrete, flat ceilings 3 are in the area of these zones in accordance with the requirements of the thrust cover in order to increase the load-bearing capacity of zones subjected to shear forces, in particular zones subject to punching shear the flat ceiling 3 arranged shear reinforcement elements 1 are provided, for example are attached accordingly by means of fastening wires on the underside of the upper horizontal bending reinforcement 4.

Bei entsprechender Ausbildung der schraubenlinienförmigen Schubbewehrungselementen 1 ist es auch möglich, diese von oben horizontal in die obere Biegebewehrung einzuhängen, wobei sie im Windungsdurchmesser derart bemessen sind, daß sie die untere Biegebewehrung nach unten nicht überragen.With a corresponding design of the helical shear reinforcement elements 1, it is also possible to hang them horizontally from above into the upper bending reinforcement, the dimensions of the winding diameter being such that that they do not protrude down the lower bending reinforcement.

In den Figuren 6 bis 14 sind drei weitere beispielsweise Ausführungsformen von mit je einem Montageeisen 5 fest verbundenen Schubbewehrungselementen 1 dargestellt.FIGS. 6 to 14 show three further exemplary embodiments of shear reinforcement elements 1, each of which is firmly connected to a mounting iron 5.

Die Montageeisen 5 dienen dabei zur Befestigung der einbaufertig vorfabrizierten Schubbewehrungselemente 1 mittels Drähten 6 an der oberen Biegebewehrung 4, wie dies z.B. aus den Figuren 13 und 14 ersichtlich ist. Die Bewehrung weist dabei noch eine untere Biegebewehrung 7 auf. Selbstverständlich ist es auch möglich, daß die Montageeisen 5 mit dem zugeordneten Schubbewehrungselement 1 verschweißt sind, und es ist auch denkbar, daß die Schubbewehrungselemente 1 zu ihrer besseren Verankerung im Beton mit zusätzlich mit ihnen verschweißten Verankerungseisen versehen sind.The assembly iron 5 serve to fasten the prefabricated shear reinforcement elements 1 by means of wires 6 to the upper bending reinforcement 4, as is e.g. 13 and 14 can be seen. The reinforcement also has a lower bending reinforcement 7. Of course, it is also possible that the assembly iron 5 are welded to the associated shear reinforcement element 1, and it is also conceivable that the shear reinforcement elements 1 are provided with anchoring irons additionally welded to them for better anchoring in the concrete.
