Abstract

A shear reinforcement for, in particular, screeds and the like comprises a round bar (1) which is encompassed by a separating layer (2), subdivided a number of times, and embedded in the screed (3) by means of spacers (4). The shear reinforcement effectively prevents the screed from bulging out at the expansion joints. <IMAGE>

Description

Die Erfindung betrifft eine Scherbewehrung für Bauteile mit hydraulischem Bindemittel, insbesondere für Estriche, Betondecken und Betonflächen, gemäß Oberbegriff des Anspruches 1.The invention relates to a shear reinforcement for components hydraulic binder, especially for screeds, concrete ceilings and concrete surfaces, according to the preamble of claim 1.

Um Bauteile, insbesondere Estriche, Betondecken und Betonoberflächen an Dehn-, Schnitt- und Tagesfugen gegen horizontale und vertikale Veränderungen aufzufangen, die zum Teil erhebliche Bauschäden verursachen, werden heute Dehn-, Schnitt- und Tagesfugen zum Teil mit PVC-Profilen, Kunststoff oder bituminösen Vergußmassen vergossen. Diese nehmen zwar die horizontalen Bewegungen auf, den vertikalen Bewegungen, halten diese Stoffe aus verschiedenen Gründen nicht stand.For components, especially screeds, concrete ceilings and concrete surfaces on expansion, cut and day joints against horizontal and to absorb vertical changes, some of which are significant Construction damage, expansion, cutting and Day joints, partly with PVC profiles, plastic or bituminous Potting compounds. These take the horizontal one Movements on, the vertical movements, hold these substances for various reasons.

Schnitt- und Tagesfugen werden heute gegen vertikale Veränderungen oder Verformungen nach dem Austrocknen mit Epoxitharz vergossen, aber auch diese Art der Verklebung haben in den meisten Fällen keinen Erfolg und führen ebenfalls zu Bauschäden, wie beispielsweise Absacken der einzelnen Beton-Platten, bei Fahrbahnen/Lagerhallen.Cut and day joints are used today against vertical changes or deformation after drying with epoxy resin shed, but also have this type of gluing in the mostly unsuccessful and also lead to structural damage, such as sagging of the individual concrete slabs Roadways / warehouses.

Bei Estrichen sind die Schäden noch gravierender. Ein Beispiel zeigt sich an Türschwellen, beim Austrocknen, verformen und schrumpfen naturgemäß die Estriche, so daß diese vor der Verlegung der Nutzbeläge heute entgegen der Regeln ebenfalls mit starren Kunststoffen vergossen werden müssen, da nichts Besseres auf dem Markt erhältlich ist. Ferner müssen durch die Verformungen die Estriche mit enormen Aufwand noch abgeschliffen werden.With screeds, the damage is even more serious. An example shows up on door thresholds, when drying out, deforming and naturally the screeds shrink, so that these before laying of the floor coverings today, contrary to the rules rigid plastics need to be potted as nothing better is available on the market. Furthermore, due to the deformations the screeds are still sanded down with enormous effort.

Der Erfindung liegt daher die Aufgabe zugrunde, zur Beseitigung der geschilderten Nachteile eine Scherbewehrung der gattungsgemäßen Art zu schaffen, das in einfacher Weise herzustellen und einzubauen ist, die statischen Grundsätze erfüllt, unabhängig von Belastungen und in Freiflächen von Temperaturschwankungen.The invention is therefore based on the object of elimination of the disadvantages described a shear reinforcement of the generic type Kind of creating that in a simple way and must be installed that meets the static principles, independently of loads and in open spaces of temperature fluctuations.

Diese Aufgabe wird durch die Merkmale des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen sind in den weiteren Ansprüchen der Erfindung beschrieben.This object is solved by the features of claim 1. Advantageous embodiments are in the further claims of the Invention described.

Die erfindungsgemäß ausgestattete Scherbewehrung, die sich insbesondere für Estriche-, Betondecken- und Betonflächen eignet, die bisher erhebliche Probleme hervorgerufen haben, eignet sich auch für jedes andere Bauteil, das mit hydraulischen oder synthetischen Bindemitteln hergestellt wird, in die die Schnitt- und Tagesfugen eingebaut werden müssen.The shear reinforcement equipped according to the invention, the especially for screed, concrete ceiling and concrete surfaces suitable, which have caused considerable problems so far, is also suitable for any other component with hydraulic or synthetic binders in which the Cut and day joints must be installed.

Die Scherbewehrung besteht je nach den Erfordernissen aus Rundstahl oder Rundeisen, sowie Stärke und Länge. Das Grundelement Eisen oder Stahl, ist mit einer Trennschicht, insbesondere mit einer Kunststoffhülle überzogen, die mehrmals in sich getrennt ist. Die Scherbewehrung ist zur besseren Plazierung mit zwei in der Höhe verstellbaren Kunststofffüßen ausgestattet. Depending on the requirements, the shear reinforcement consists of round steel or round bars, as well as strength and length. The basic element Iron or steel, is with a separation layer, especially with covered with a plastic cover that separated several times is. The shear reinforcement is for better placement with two adjustable plastic feet.  

Die erfindungsgemäß ausgestattete Scherbewehrung, kann daher nicht nur leicht hergestellt und eingebaut werden, sondern sie gewährleistet eine dauerhafte und bleibende Verbindung und horizontale, natürliche Bewegung der einzelnen Bauteile, insbesondere der Estriche-, Betondecken und Betonflächen.The shear reinforcement equipped according to the invention can therefore not only be easily manufactured and installed, but it ensures a permanent and lasting connection and horizontal, natural movement of the individual components, especially the screed, concrete ceilings and concrete surfaces.

Von besonderem Vorteil ist schließlich auch noch der entscheidend verringerte Herstellungspreis der erfindungsgemäßen Scherbewehrung, der gegenüber dem Preis der bisher verwendeten Materialien, aber auch der Einbaukosten, die sich um mindestens um die Hälfte verringern.After all, that is also of particular advantage reduced manufacturing price of the shear reinforcement according to the invention, compared to the price of the materials used so far, but also the installation costs, which are at least about Reduce half.

Die Erfindung wird in den folgenden anhängenden Zeichnungen näher erläutert. Diese zeigen in:The invention is illustrated in the following accompanying drawings explained. These show in:

Fig. 1 und 2 die Scherbewehrung erfindungsgemäß im uneingebauten Zustand. Fig. 1 and 2, the shear reinforcement according to the invention in the uninstalled state.

Fig. 3 die Scherbewehrung im eingebauten Zustand bei einem Estrich. Fig. 3 shows the shear reinforcement in the installed state with a screed.

Wie aus der Zeichnung ersichtlich, ist die dargestellte Scherbewehrung, eine dauerhafte, feste Verbindung zwischen zwei Bauteilen die horizontal das normale Dehn- und Schwindverhalten von Beton durch die Trennschicht gewährleistet.As can be seen from the drawing, the one shown Shear reinforcement, a permanent, firm connection between two components that horizontally show normal expansion and contraction behavior guaranteed by concrete through the interface.

Vertikale Bewegungen, die zu Schäden und Unfallgefahren bei Betonfahrbahnen, Lagerhallendecken, Estriche führen, werden durch die eingebaute Scherbewehrung verhindert. Wie beispielsweise durch den Einbau der Scherbewehrung verhindert wird, daß beim Austrocknen die Estriche, Betondecken, und Betonflächen an den Dehn- und Schnittfugen, Kanten hochgehen und schüsseln.Vertical movements that contribute to damage and accident hazards Concrete carriageways, warehouse ceilings and screeds run through the built-in shear reinforcement prevents. Like for example the installation of the shear reinforcement prevents when drying out the screeds, concrete ceilings and concrete surfaces at the expansion and kerf, edges and bowls.

Der in der Zeichnung dargestellte Abstandshalter, ist so konstruiert, daß gewährleistet ist, daß die Scherbewehrung funktionsgerecht für jede Betonstärke ohne besondere Schwierigkeit, in die Mitte eines Belages eingebaut werden kann.The spacer shown in the drawing is like this constructed to ensure that the shear reinforcement functional for any concrete thickness without any particular difficulty, can be installed in the middle of a covering.
