Description

Die vorliegende Erfindung betrifft Armierungselemente gemäß dem Obergebriff des Anspruchs 1, zur Erstellung von Eisenbetonkonstruktionen, insbesondere zur Erstellung von Anschlüssen von Wänden an Boden-Deckenplatten und zur Verbindung zweier Wände, sowie zur Erstellung von Streifenfundamenten.The present invention relates to reinforcement elements according to the preamble of claim 1, for the creation of reinforced concrete structures, in particular for the creation of connections of walls to floor-ceiling slabs and for connecting two walls, and for the creation of strip foundations.

Herkömmlich wird häufig ein solches Armierungselement auf dem Bauplatz am Ort des Einbaus geformt und mit speziellen Drähten gebunden. Dies ist ausserordentlich arbeitsintensiv, hat jedoch den Vorteil, dass das Armierungselement leicht den jeweiligen bauspezifischen Gegebenheiten angepasst werden kann. Bei der vielzahl der verschiedenen Anwendungen von Armierungselementen müssen daher vorgefertigte Armierungselemente äusserst genau durchdacht sein. Trotz ihrer vorgegebenen Form soll ein Armierungselement möglichst vielfältig einsetzbar sein.Conventionally, such a reinforcement element is often formed on the building site at the place of installation and tied with special wires. This is extremely labor-intensive, but has the advantage that the reinforcement element can be easily adapted to the specific building conditions. With the large number of different applications of reinforcement elements, prefabricated reinforcement elements must therefore be very carefully thought out. In spite of their predetermined shape, a reinforcement element should be able to be used in as many ways as possible.

Zur Erstellung von Anschlüssen von Wänden an Boden-Deckenplatten und zur Verbindung zweier wände eignet sich insbesondere ein Armierungselement gemäss der CH-A 642 131. Dieses Armierungselement besteht aus einer Anzahl gleicher, parallel zu einander angeordneter, haarnadelförmig gebogener Bügel. Die Bügel sind durch mindestens drei in zwei zueinander rechtwinklig angeordneten Ebenen liegenden Stäben unlösbar untereinander verbunden. Dieses Armierungselement hat sich vielfach bewährt. Je nach der Dicke der zu erstellenden Wand, sowie nach der geforderten Festigkeit sind unterschiedlich dimensionierte Elemente erforderlich. Dies bedingt zwangsläufig eine relativ grosse Lagerhaltung.A reinforcement element according to CH-A 642 131 is particularly suitable for creating walls from floor-to-ceiling slabs and for connecting two walls. This reinforcement element consists of a number of identical, hairpin-shaped brackets arranged parallel to one another. The brackets are inseparably connected to one another by at least three bars lying in two planes arranged at right angles to one another. This reinforcement element has proven itself many times. Depending on the thickness of the wall to be created and the required strength, differently dimensioned elements are required. This inevitably requires a relatively large inventory.

Zur Erstellung von Streifenfundamenten ist das vorgenannte Armierungselement nur bedingt geeignet. Hier hat man sich bisher damit beholfen, einen Streifen aus einem herkömmlichen Armierungsnetz heraus zu schneiden. Dies führt jedoch zu relativ grossen, nicht mehr verwendbaren Resten.The aforementioned reinforcement element is only suitable to a limited extent for the creation of strip foundations. So far, people have managed to cut a strip out of a conventional reinforcement net. However, this leads to relatively large residues that can no longer be used.

Bedenkt man die relativ geringe Gewinnspanne, die bei Armierungselementen vorhanden ist, so erkennt man, dass auch der platzsparenden und einfachen Stapelung solcher Elemente Rechnung getragen werden muss. Bei ungünstiger Stapelungsdichte erhöhen sich nämlich nicht nur die Lagerkosten, sondern auch die Transportspesen.If you consider the relatively small profit margin that exists with reinforcement elements, you can see that the space-saving and simple stacking of such elements must also be taken into account. If the stacking density is unfavorable, not only the storage costs increase, but also the transport costs.

Es ist daher die Aufgabe der vorliegenden Erfindung, Armierungselemente der eingangs genannten Art zu schaffen, die vielfältig einsetzbar sind, mit einer geringeren Anzahl verschiedener Dimensionen auskommt und eine einfache und dichte Stapelung ermöglichen.It is therefore the object of the present invention to provide reinforcing elements of the type mentioned at the outset, which can be used in a variety of ways, manages with a smaller number of different dimensions and enables simple and dense stacking.

Diese vielschichtige Aufgabe löst ein Armierungselement wie eingangs beschrieben mit den Merkmalen des kennzeichnenden Teiles des Patentanspruches 1.This multi-layered task is solved by a reinforcing element as described in the introduction with the features of the characterizing part of patent claim 1.

In der Zeichnung ist ein bevorzugtes Ausführungsbeispiel des Erfindungsgegenstandes dargestellt und verschiedene Verwendungsbeispiele gezeigt.

  • Figur 1 eine perspektivische Darstellung eines Ausführungsbeispieles des Erfindungsgegenstandes und
  • Figur 2 denselben in der Seitenansicht
  • Figur 3 und 4 zeigen zwei Varianten der Zusammenfügung zweier Elemente für die Verbindung einer Wand mit einer Boden-Deckenplatte beziehungsweise zur Verbindung zweier Wände
  • Figur 5 stellt die Zusammenfassung zweier Elemente zu einer Armierung für Streifenfundamente dar.
In the drawing, a preferred embodiment of the subject matter of the invention is shown and various examples of use are shown.
  • Figure 1 is a perspective view of an embodiment of the subject matter of the invention and
  • Figure 2 the same in side view
  • Figures 3 and 4 show two variants of joining two elements for connecting a wall to a floor-ceiling plate or for connecting two walls
  • FIG. 5 shows the combination of two elements to form a reinforcement for strip foundations.

Die erfindungsgemässen Armierungselemente bestehen aus einer vielzahl von parallel zueinander verlaufenden Stäben, die so rechtwinklig abgebogen sind, dass sie Bügel 1 zwei unterschiedlich lange Schenkel bilden. Die kürzeren Schenkel 2 verlaufen in einer Ebene, während die längeren Schenkel 3 in einer zweiten rechtwinklig dazu verlaufenden Ebene liegen. Die längeren Schenkel 3 sind um ein mehrfaches länger als die kürzeren Schenkel 2. Die Längen der Schenkel verhalten sich etwa wie 1:4 bis 1:8. Eine etwa übliche Länge der kürzeren Schenkel beträgt 19 - 23 cm. Auf der Bügelinnenseite sind diese alle untereinander mittels Stäben verbunden. Auf den kürzeren Schenkeln 2 ist ein Stab 4 aufgeschweisst, der etwa 5 cm von der Biegungsstelle 5 entfernt verläuft. Diese Distanz ist so gewählt, dass beim Zusammenstellen zweier Elemente diese auf die dünnste noch übliche Wandstärke zusammenschiebbar sind.The reinforcing elements according to the invention consist of a large number of bars running parallel to one another, which are bent at right angles so that they form brackets 1 two legs of different lengths. The shorter legs 2 run in one plane, while the longer legs 3 lie in a second plane running at right angles to them. The longer legs 3 are several times longer than the shorter legs 2. The lengths of the legs behave approximately as 1: 4 to 1: 8. An approximately usual length of the shorter legs is 19-23 cm. On the inside of the bracket, these are all connected to one another by means of rods. A rod 4 is welded onto the shorter legs 2 and runs approximately 5 cm from the bending point 5. This distance is chosen so that when two elements are put together, they can be pushed together to the thinnest wall thickness still common.

Parallel zum Stab 4 sind die längeren Schenkel 3 der Bügel 1 mit einem zweiten Stab 6 untereinander verbunden. Der Abstand jenes Stabes 6 von der Biegestelle 5 entspricht der Summe des Durchmessers eines Stabes, äus dem die Bügel 1 geformt sind plus dem Durchmesser des Verbindungsstabes 4. Dies ist wiederum für das Zusammenfügen zweier Elemente, wie noch beschrieben wird, von Bedeutung. Für das erfindungsgemässe System nicht von Wichtigkeit, ist ein zweiter paralleler Verbindungsstab 7 an den langen Schenkeln 3. Er dient lediglich zur Versteifung des Elementes. Seine Distanz zur Biegestelle 5 ist nicht bestimmt. Es ist jedoch vorteilhaft, ihn relativ nahe dem Verbindungsstab 6 anzuschweissen, damit die Enden der langen Schenkel 3 möglichst frei bleiben. Zur Erstellung eines Armierungskorbes, wie er beispielsweise für die Verbindung einer Wand mit einer Boden-Deckenplatte benötigt wird, sind zwei erfindungsgemässe Armierungselemente erforderlich. Sie lassen sich auf zwei verschiedene Arten zusammenfügen. Die in der Figur 3 dargestellte Variante wird dann verwendet, wenn ein erstes Element bereits an der Armierung angeschlossen ist. Die Armierung der Boden-Deckenplatte üblicherweise ein einfaches Armierungsnetz, ist hier nicht dargestellt.Parallel to the rod 4, the longer legs 3 of the bracket 1 are connected to one another with a second rod 6. The distance of that rod 6 from the bending point 5 corresponds to the sum of the diameter of a rod, the brackets 1 are formed plus the diameter of the connecting rod 4. This in turn is important for the joining together of two elements, as will be described. A second parallel connecting rod 7 on the long legs 3 is not important for the system according to the invention. It only serves to stiffen the element. Its distance to the bending point 5 is not determined. However, it is advantageous to weld it relatively close to the connecting rod 6 so that the ends of the long legs 3 remain as free as possible. To create a reinforcement cage, as is required, for example, for connecting a wall to a floor-ceiling plate, two reinforcement elements according to the invention are required. They can be put together in two different ways. The variant shown in FIG. 3 is used when a first element is already connected to the reinforcement. The reinforcement of the floor-ceiling slab, usually a simple reinforcement network, is not shown here.

Das zweite Armierungselement lässt sich nun exakt in das erste Element einschieben. Hierbei sind die kurzen Schenkel 2 beider Elemente gegeneinandergerichtet. Die kürzeren Schenkel 2 des zweiten Elementes liegen auf dem Verbindungsstab 4 des ersten Elementes auf. Gleichzeitig untergreifen die Enden der kürzeren Schenkel den Verbindungsstab 6 an den längeren Schenkeln 3 des ersten Armierungselementes. Damit die längeren Schenkel 3 beider Elemente etwa parallel zu liegen kommen, muss der Abstand des Verbindungsstabes 6 zur Biegungsstelle 5 der Bügel 1 möglichst genau der Summe der Druchmesser eines kürzeren Schenkels 2 und des Verbindungsstabes 4 entsprechen. Der Durchmesser der Verbindungsstäbe wird üblicherweise geringer bemessen als der Durchmesser der Stäbe aus denen die Bügel 1 gebogen werden.The second reinforcement element can now be inserted exactly into the first element. Here, the short legs 2 of both elements are directed towards each other. The shorter legs 2 of the second element rest on the connecting rod 4 of the first element. At the same time, the ends of the shorter legs reach under the connector extension rod 6 on the longer legs 3 of the first reinforcing element. So that the longer legs 3 of both elements come to lie approximately parallel, the distance of the connecting rod 6 to the bending point 5 of the bracket 1 must correspond as closely as possible to the sum of the diameter of a shorter leg 2 and the connecting rod 4. The diameter of the connecting rods is usually dimensioned smaller than the diameter of the rods from which the brackets 1 are bent.

Neben dem bereits genannten Grund für die Einbaulage nach Figur 3 sei noch vermerkt, dass diese Art der Zusammenstellung zweier Elemente auch für extrem dünne Wände geeignet ist. Die längeren Schenkel beider Elemente lassen sich bis etwa auf den Abstand des Verbindungsstabes 4 von der Biegungsstelle 5 gegeneinander schieben, wie dies durch den Pfeil S angedeutet wird.In addition to the reason already mentioned for the installation position according to FIG. 3, it should also be noted that this type of combination of two elements is also suitable for extremely thin walls. The longer legs of both elements can be pushed against each other up to approximately the distance of the connecting rod 4 from the bending point 5, as is indicated by the arrow S.

In der zweiten Einbaulage wie in Figur 4 dargestellt wird, können die beiden Elemente bereits vor dem Einbringen in die Verschalung zusammengesteckt werden. Dies erfolgt wie durch die strichlinierte Zwischenlage illustriert, in dem man das eine Element gegenüber dem anderen etwas kippt und dann mit dem kürzeren Schenkel des einen Elementes unter den Verbindungsstab 4 des anderen Elementes durchfährt. Auch hier lassen sich die beiden Elemente zueinander verschieben und damit eine grosse Palette unterschiedlichster Weiten etwa von 9 - 27 cm erreichen.In the second installation position, as shown in FIG. 4, the two elements can be put together before being introduced into the casing. This is done as illustrated by the dash-lined intermediate layer in which one element is tilted slightly relative to the other and then passed through with the shorter leg of one element under the connecting rod 4 of the other element. Here, too, the two elements can be shifted towards each other and a wide range of different widths of around 9 - 27 cm can be achieved.

Vorteilhaft erweist sich bei dieser Zusammensteckweise, dass die kürzeren Schenkel beider Elemente in einer Ebene liegen.In this way of assembling, it proves advantageous that the shorter legs of both elements lie in one plane.

Vorteilhaft ist es auch, dass das Armierungselement sich zusätzlich zur Armierung von Streifenfundamenten eignet. Hierbei werden im Gegensatz zu den vorbeschriebenen Varianten nicht die küzeren, sondern die längeren Schenkel 3 in einer Ebene gegeneinander gerichtet verlegt. Die längeren Schenkel des einen Elementes werden dabei unter den Verbindungsstäben 6,7 des anderen Elementes hindurch geschoben. Je nach der benötigten Breite lassen sich die beiden Elemente beliebig ineinander schieben oder auseinander ziehen.It is also advantageous that the reinforcement element is also suitable for reinforcing strip foundations. In contrast to the variants described above, it is not the shorter, but rather the longer legs 3 that are laid in a plane directed towards each other. The longer legs of one element are pushed under the connecting rods 6, 7 of the other element. Depending on the required width, the two elements can be pushed or pulled apart as required.

Es bedarf keiner besonderen Erklärung, dass diese Armierungselemente in äusserst dichter Packung gestapelt werden können. Hierzu ist es nicht erforderlich, die Elemente kompliziert ineinander zu verschachteln.There is no need for a special explanation that these reinforcement elements can be stacked in an extremely tight package. It is not necessary for this to complicatedly nest the elements into one another.
