Abstract

Reinforcement for reinforcing layers crossing over one another, in the form of a reinforcing cross or of a lattice with connecting devices (22, 23; 31 ..., 41 ...) for continuing reinforcing rods (49). Gaps (21) in the reinforcing cross serve for anchoring in concrete and for passing through vertical reinforcing rods. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Bewehrung für sich überkreuzende Bewehrungslagen.The invention relates to a reinforcement for crossing reinforcement layers.

Bei der Herstellung von Gebäuden kommen sich kreuzende Bewehrungen vor, deren ordentliche Ausführung für die Belastbarkeit von Stahlbetonbalkenkreuzungen äußerst wichtig ist. Diese Bewehrungen sind häufig schwierig auszuführen, insbesondere wenn die Baustähle mehrlagig verarbeitet werden müssen und wenn außerdem noch senkrecht laufende Bewehrungsstäbe durch die Kreuzungsbereiche hindurchgeführt werden müssen, weil Säulen oder Pfeiler zu erstellen sind. Die Durchführung dieser Arbeiten ist lohnintensiv und zeitraubend. In der Praxis kommen Fälle vor, daß die berechneten Bewehrungszulagen nicht untergebracht werden können.In the manufacture of buildings, crossing reinforcements occur, the proper execution of which is extremely important for the resilience of reinforced concrete beam crossings. These reinforcements are often difficult to carry out, especially if the structural steels have to be processed in multiple layers and if vertical reinforcement bars also have to be led through the crossing areas because columns or pillars have to be created. Performing this work is costly and time consuming. In practice there are cases where the calculated reinforcement allowances cannot be accommodated.

Durch die FR-A-1 522 516 ist es bekannt, daß erste und zweite Bewehrungsstäbe sich unter Bildung von Knotenpunkten überschneiden, wobei Abstände zwischen den Bewehrungsstäben freigelassen sind, die zur Aufnahme von weiteren Bewehrungsstäben ausreichend groß sind.From FR-A-1 522 516 it is known that first and second reinforcing bars overlap to form nodes, leaving spaces between the reinforcing bars that are sufficiently large to accommodate further reinforcing bars.

Der Erfindung liegt die Aufgabe zugrunde, den Bewehrungseinbau wesentlich zu erleichtern.The invention is based, to facilitate the installation of reinforcement significantly.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Bewehrungsstäbe sich an den Knotenpunkten durchdringen und ein Bewehrungskreuz bilden.This object is achieved in that the reinforcement bars penetrate at the nodes and form a reinforcement cross.

Weitere Merkmale der Erfindung sind in den Unteransprüchen gekennzeichnet.Further features of the invention are characterized in the subclaims.

Dieses Bewehrungskreuz hat den besonderen Vorteil, daß die statische Höhe für die sich kreuzenden Bewehrungen gleich bleibt und daß dadurch Stahl eingespart werden kann. Die Eisenabstände bleiben gewahrt, und es ist genügend Platz für eventuell durchgehende Säuleneisen vorhanden. Wegen der größeren Freiräume ist es nunmehr einfacher, den Beton in den Balkenkreuzungsbereich einzubringen und die Voraussetzungen nach den DIN-Normen zu erfüllen. Der maximal zulässige Bewehrungsgehalt im Balkenkreuzungsbereich wird überschaubar und läßt sich besser kontrollieren.This reinforcement cross has the particular advantage that the static height for the crossing reinforcements remains the same and that steel can be saved. The Iron spacing is maintained and there is enough space for any column iron that may go through. Because of the larger free spaces, it is now easier to pour the concrete into the area where the beams cross and to meet the requirements of the DIN standards. The maximum permissible reinforcement content in the area of the bar crossing becomes manageable and can be better controlled.

Das Bewehrungskreuz nach Fig. 1 und 2 enthält zwei Serien von Bewehrungsstäben 1 bis 6 und 7 bis 12, die sich im rechten Winkel schneiden und ein Gitter bilden. Die Überschneidungsstellen sind als Knotenpunkte 20 ausgebildet. Zwischen den Stäben sind Lücken 21 freigelassen, die jeweils von vier Knotenpunkten 20 umgeben sind. Die Abstände benachbarter Stäbe voneinander und damit die Weite der Lücken 21 sind genügend groß, um gegebenenfalls weitere Bewehrungsstäbe senkrecht durch die Gitterebene des Bewehrungskreuzes hindurchführen zu können. An ihren Enden sind die Stäbe 1 bis 12 mit Gewinde 22 versehen, welches hier als konisches Gewinde ausgebildet ist und zum Aufschrauben je einer Verbindungsmuffe 23 dient. Die Verbindungsmuffen 23 weisen zwei Innengewinde 24 auf, wovon eines zum Anschluß eines weiterführenden Bewehrungsstabes dient. Wie dargestellt, sind die Stäbe 1, 3, 5, 7, 9, 11 gegenüber den Stäben 2, 4, 6, 8, 10, 12 um den Mindestbetrag der Länge der Verbindungsmuffen 23 versetzt, so daß sich die Verbindungsmuffen 23 gegeneinander nicht stören. Bei einem Durchmesser von 28 mm der Stäbe 1 bis 12 wird beispielsweise ein Versatz von 100 mm eingehalten, wodurch sich eine Überkraglänge der Stäbe 1, 3, 5, 7, 9, 11 von 155 mm und eine Überkraglänge der Stäbe 2, 4, 6, 8, 10, 12 von 55 mm ergibt, wenn die obere und rechte Seite des Gitters betrachtet wird. Bei dem angegebenen Durchmesser der Stäbe von 28 mm ergibt sich eine Gitterkantenlänge von 308 mm und eine Gesamtabmessung des Bewehrungskreuzes von 618 x 618 mm. Mit diesen Maßen kann eine Balkenbreite von 35 cm und mehr hergestellt werden.1 and 2 contains two series of reinforcing bars 1 to 6 and 7 to 12, which intersect at right angles and form a grid. The intersection points are designed as nodes 20. Gaps 21 are left between the bars, each of which is surrounded by four nodes 20. The spacing of adjacent bars from one another and thus the width of the gaps 21 are large enough to be able to pass further reinforcement bars perpendicularly through the lattice plane of the reinforcement cross if necessary. At their ends, the rods 1 to 12 are provided with a thread 22, which is designed here as a conical thread and is used for screwing on a connecting sleeve 23 each. The connecting sleeves 23 have two internal threads 24, one of which serves to connect a further reinforcing bar. As shown, the rods 1, 3, 5, 7, 9, 11 are offset from the rods 2, 4, 6, 8, 10, 12 by the minimum amount of the length of the connecting sleeves 23, so that the connecting sleeves 23 do not interfere with each other . With a diameter of 28 mm of rods 1 to 12, an offset of 100 mm is maintained, for example, which results in an overhanging length of rods 1, 3, 5, 7, 9, 11 of 155 mm and a cantilever length of the bars 2, 4, 6, 8, 10, 12 of 55 mm results when the upper and right side of the grid is viewed. With the specified diameter of the bars of 28 mm, this results in a lattice edge length of 308 mm and a total dimension of the reinforcement cross of 618 x 618 mm. With these dimensions, a beam width of 35 cm and more can be produced.

Das in Fig. 1 und 2 dargestellte Bewehrungskreuz ist aus Gußstahl hergestellt, der die Qualität GS 20 MN5 St. 520 aufweisen kann.The reinforcement cross shown in Fig. 1 and 2 is made of cast steel, which can have the quality GS 20 MN5 St. 520.

In Fig. 3 ist eine zweite Ausführungsform des Bewehrungskreuzes dargestellt, für die angenommen wird, daß die Gitterstäbe einen Durchmesser von 14 mm haben. Im dargestellten Ausführungsbeispiel sind jeweils acht Stäbe pro Serie vorgesehen, so daß sich 64 Knotenpunkte und 49 Lücken ergeben. Wegen des geringeren Durchmessers von 14 mm der Stäbe genügt ein Versatz von 58 mm der jeweiligen Enden voneinander. Gesehen vom Gitternetz aus, wird eine Überkraglänge der Stäbe von 34 bzw. 92 mm eingehalten. Die Gesamtabmessung des Elements beträgt 436 x 436 mm. Die Herstellung des Gitterkreuzes kann in gleicher Weise aus Gußstahl erfolgen wie beim ersten Ausführungsbeispiel.In Fig. 3 a second embodiment of the reinforcement cross is shown, for which it is assumed that the bars have a diameter of 14 mm. In the illustrated embodiment, eight rods per series are provided, so that there are 64 nodes and 49 gaps. Because of the smaller diameter of 14 mm of the rods, an offset of 58 mm between the respective ends is sufficient. Seen from the grid, the cantilever length of the bars is 34 or 92 mm. The overall dimension of the element is 436 x 436 mm. The cross can be made from cast steel in the same way as in the first embodiment.

Fig. 4 zeigt eine Variante des Bewehrungskreuzes hinsichtlich seiner Herstellungsart. Es wird von einer Stahlplatte entsprechender Dicke ausgegangen, und die Form wird durch mechanische Bearbeitung, insbesondere Stanzen, Bohren oder Lochen, hergestellt. Die Lücken 21 sind in diesem Fall rund, und die Übergänge zwischen den Gitterstäben sind abgerundet. Derartige Abrundungen können übrigens auch bei der Herstellungsart durch Gießen eingehalten werden.Fig. 4 shows a variant of the reinforcement cross with regard to its type of manufacture. A steel plate of appropriate thickness is assumed and the shape is produced by mechanical processing, in particular stamping, drilling or punching. The gaps 21 are round in this case and the transitions between the bars are rounded. Incidentally, such roundings can also be maintained in the type of manufacture by casting.

Anstelle der konischen Enden der Gitterstäbe sind auch zylindrische Enden mit entsprechendem Gewinde brauchbar. Wenn der Anschluß der weiterführenden Bewehrungsstäbe durch Schweißen erfolgen soll, wird man kein Gewinde vorsehen. Bei dieser Verbindungsart ist es im übrigen nicht immer notwendig, einen Versatz der Enden der Gitterstäbe einzuhalten.Instead of the conical ends of the bars, cylindrical ends with a corresponding thread can also be used. If the additional reinforcement bars are to be connected by welding, no thread will be provided. At this type of connection, it is not always necessary to maintain an offset of the ends of the bars.

Fig. 5 und 6 zeigen ein plattenförmiges Bewehrungskreuz, welches aus einer Stahlplatte von beispielsweise 22 mm Stärke und 320 mm Länge bzw. Breite hergestellt worden ist. In die Platte sind 7 x 7 Bohrungen 21 von beispielsweise 20 mm Durchmesser angebracht, zwischen denen Knotenpunkte 20 stehenbleiben. Die Knotenpunkte 20 ergänzen sich entlang der horizontalen Linien bzw. der vertikalen Spalten zu jeweiligen Serien von Bewehrungsstäben, deren Enden jeweils ein Innengewinde 31 bis 38 bzw. 41 bis 48 aufweist, welches zylindrisch oder konisch ausgebildet sein kann und zum Anschluß von weiterführenden Bewehrungsstäben 49 ausgebildet ist, wie dies in Fig. 6 angedeutet ist. Die Gewindebohrungen 31 bis 38 bzw. 41 bis 48 haben in dem Ausführungsbeispiel ein Maß von M14 und einen Abstand voneinander von 34 mm sowie einen Randabstand von 41 mm.5 and 6 show a plate-shaped reinforcement cross which has been produced from a steel plate, for example 22 mm thick and 320 mm long or wide. In the plate 7 x 7 holes 21 are made, for example 20 mm in diameter, between which nodes 20 remain. The nodes 20 complement each other along the horizontal lines or the vertical columns to form a respective series of reinforcing bars, the ends of which each have an internal thread 31 to 38 or 41 to 48, which can be cylindrical or conical, and are designed to connect additional reinforcing bars 49 is, as indicated in Fig. 6. In the exemplary embodiment, the threaded bores 31 to 38 or 41 to 48 have a dimension of M14 and a distance from one another of 34 mm and an edge distance of 41 mm.

Es versteht sich, daß die angegebene Anzahl der Bewehrungsstäbe und die Abmaße des Bewehrungskreuzes je nach den statischen Erfordernissen abgewandelt werden kann.It is understood that the specified number of reinforcement bars and the dimensions of the reinforcement cross can be modified depending on the structural requirements.

Fig. 7 zeigt ein stark reduziertes Bewehrungskreuz, bei dem zwei erste Bewehrungsstäbe 1 und 5 sowie ein zweiter Bewehrungsstab 7 gegenüber der Ausführungsform nach Fig. 1 übriggeblieben sind. Die Lücke 21 ist demnach besonders weit. Am Ende tragen die Stäbe 1, 5 und 7 jeweilige Gewinde 22, so daß jeder Stab über eine zugehörige Gewindemuffe 23 mit einem weiterführenden Bewehrungsstab verbunden werden kann.FIG. 7 shows a greatly reduced reinforcement cross, in which two first reinforcement bars 1 and 5 and a second reinforcement bar 7 are left in comparison with the embodiment according to FIG. 1. The gap 21 is therefore particularly wide. At the end, the bars 1, 5 and 7 carry respective threads 22, so that each bar can be connected to a further reinforcing bar via an associated threaded sleeve 23.

Fig. 8 zeigt die Verwendung des Bewehrungskreuzes nach Fig. 7. In Baukonstruktionen kommen senkrechte Pfeiler 50 und davon abzweigende Balken 51 vor. In dem Pfeiler ist eine Anzahl von Bewehrungsstäben einzubauen, und hiervon seien die Bewehrungsstäbe 52, 53, 54, 55 herausgegriffen. Diese Bewehrungsstäbe werden mit den Stäben 1 und 5 des Bewehrungskreuzes über Muffen 23 verbunden, so daß sich jeweils durchgehende Bewehrungsstäbe für den Pfeiler 50 ergeben. Durch entsprechende Bemessung der Längen der Bewehrungsstäbe 52 bis 55 wird die richtige Höhe für den Bewehrungsstab 7 erzielt, an den über eine Muffe 23 ein horizontaler Bewehrungsstab 57 anzuschließen ist. Es sei angenommen, daß in bestimmtem Abstand von diesem Bewehrungsstab 57 ein weiterer Bewehrungsstab 58 angeordnet werden soll. Dieser wird an der Schalung gestützt oder am oberen Stab 57 angehängt, wie es dem Fachmann bekannt ist. Das nach oben gebogene Ende des Stabes 58 hat in der Lücke 21 des Bewehrungskreuzes ausreichend Platz, um sich im Beton zu verankern, wie es den statischen Voraussetzungen entspricht. In gleicher Weise können weitere Stäbe des Pfeilers 50 und des Balkens 51 miteinander verbunden werden, so daß problemlos die richtigen Abstände eingehalten werden.FIG. 8 shows the use of the reinforcement cross according to FIG. 7. Vertical pillars 50 and beams 51 branching therefrom occur in building constructions. A number of reinforcing bars are to be installed in the pillar, of which the reinforcing bars 52, 53, 54, 55 are selected. These reinforcement bars are connected to bars 1 and 5 of the reinforcement cross via sleeves 23, so that there are continuous reinforcement bars for the pillar 50 surrender. By appropriate dimensioning of the lengths of the reinforcing bars 52 to 55, the correct height for the reinforcing bar 7 is achieved, to which a horizontal reinforcing bar 57 is to be connected via a sleeve 23. It is assumed that a further reinforcing bar 58 is to be arranged at a certain distance from this reinforcing bar 57. This is supported on the formwork or attached to the upper rod 57, as is known to those skilled in the art. The upwardly bent end of the rod 58 has enough space in the gap 21 of the reinforcement cross to anchor itself in the concrete, as it corresponds to the static requirements. In the same way, further rods of the pillar 50 and the beam 51 can be connected to one another, so that the correct distances are easily maintained.

Es versteht sich, daß außer den dargestellten Ausführungsbeispielen noch andere Bewehrungskreuze hergestellt werden können, bei denen sich die Anzahl der gewählten Gitterstäbe sowie ihr Durchmesser nach der beabsichtigten Anwendung richtet. Auch die Abstände der Gitterstäbe voneinander können von den zuvor erläuterten Ausführungsbeispielen abweichen. Wichtig ist, daß der Beton genügend Platz hat, durch die Lücken 21 hindurchzutreten, um einen festen Verbund zwischen dem Betonbereich oberhalb und unterhalb des Gitterkreuzes zu schaffen.It goes without saying that, in addition to the exemplary embodiments shown, other reinforcement crosses can also be produced in which the number of selected bars and their diameter depend on the intended application. The spacing of the lattice bars from one another can also differ from the exemplary embodiments explained above. It is important that the concrete has enough space to pass through the gaps 21 in order to create a firm bond between the concrete area above and below the cross.

Während sich im allgemeinen die Stäbe unter einem Winkel von 90° schneiden, können für Sonderfälle auch andere Winkel gewählt werden.While the bars generally intersect at an angle of 90 °, other angles can also be selected for special cases.
