Description
Die Erfindung bezieht sich auf ein Bewehrungsanschlusselement gemäß Anspruch 1.The invention relates to a reinforcement connection element according to claim 1.
Bewehrungsanschlüsse mit in einem Verwahrungskasten aufgenommenen Bewehrungselementen sind seit vielen Jahren bekannt und dienen zur Herstellung einer Anschlussbewehrung zwischen einem ersten, zuerst erstellten Betonbauteil und einem zweiten, nachfolgend erstellten Betonbauteil. Der Verwahrungskasten wird bei der Anwendung an die Innenseite einer Schalungswand genagelt, wobei die über den Boden des Verwahrungskastens herausragende Bewehrung in den Schalungsinnenraum zeigt. Nach dem ersten Betoniervorgang sind der Verwahrungskasten und die über den Boden des Verwahrungskastens vorstehenden Anschlusselemente in das zuerst erstellte Betonbauteil eingebunden. Nach dem Aushärten des Betons und Entfernen der Schalung kann der Deckel des Verwahrungskastens mit Hilfe eines Hammers entfernt werden, sodass die Bewehrungselemente offen liegen. Diese können dann nach oben gebogen werden und dienen als Bewehrung für das in einem zweiten Betonierabschnitt zu betonierende zweite Betonbauteil. Der Beton des zweiten Betonbauteils füllt auch den Innenraum des Verwahrungkastens aus, so dass dieser vollständig im Beton zwischen den beiden Betonbauteilen eingebettet ist.Reinforcement connections with reinforcement elements accommodated in a storage box have been known for many years and serve to produce a connection reinforcement between a first concrete component initially produced and a second subsequently produced concrete component. The storage box is nailed in use to the inside of a formwork wall, with the projecting beyond the bottom of the storage box reinforcement in the formwork interior shows. After the first concreting process, the storage box and the connection elements protruding beyond the bottom of the storage box are integrated into the first concrete component. After hardening of the concrete and removal of the formwork, the cover of the storage box can be removed with the aid of a hammer so that the reinforcement elements are exposed. These can then be bent upwards and serve as reinforcement for the second concrete component to be concreted in a second concreting section. The concrete of the second concrete component also fills the interior of the Verwahrungkastens so that it is completely embedded in the concrete between the two concrete components.
Aus der
Solche herkömmlichen Bewehrungsanschlüsse haben den Nachteil, dass keine Fugenabdichtung integriert ist und somit die Arbeitsfuge zwischen den beiden Betonbauteilen nicht druckwasserdicht ausgeführt werden kann. Einen Ansatz zur Lösung dieses Problems zeigt die
Solche Bewehrungsanschlüsse mit zwei schlittenartigen Verwahrungskästen sind aber gegenüber herkömmlichen Rückbiegeanschlüssen mit dem Nachteil verbunden, dass sie erst ab einer Bügelbreite von 16 cm verwendet werden können. Grund hierfür ist, dass für das Fugenblech eine Mindesteinbindetiefe in den Beton von 3 cm beachtet werden muss. Der Abstand zwischen Fugenblech und der jeweils dem Fugenblech zugewandten Wandung der beiden Verwahrungskästen muss also mindestens 3 cm betragen. Damit als Bewehrungselemente Bewehrungseisen mit dem üblichen Durchmesser von 12 mm in dem jeweiligen Verwahrungskasten untergebracht werden können, muss dessen Mindestbreite 5 cm betragen. Erfordern die zu erstellenden Betonbauteile einen größeren Bewehrungsdurchmesser, so müssen auch größere Verwahrungskästen benutzt werden, wodurch sich der Abstand der aus dem Boden der Verwahrungskästen herausragenden Bewehrungselemente erhöht. Trotz der aus dem Stand der Technik bekannten Lösungen bleibt daher der Einsatz wasserdichter, mit einem Fugenblech ausgestatteter Bewehrungsanschlüsse auf relativ geringe Bewehrungsdurchmesser und große Bügelbreiten beschränkt.Such rebar connections with two slide-like storage boxes, however, are associated with the disadvantage that they can only be used from a bracket width of 16 cm compared to conventional reverse bending connections. The reason for this is that a minimum embedment depth in the concrete of 3 cm must be taken into account for the joint plate. The distance between the joint plate and each of the joint plate facing wall of the two storage boxes must therefore be at least 3 cm. So that reinforcing bars with the usual diameter of 12 mm can be accommodated in the respective storage box as reinforcement elements, its minimum width must be 5 cm. Require the concrete components to be created a larger diameter reinforcement, so larger storage boxes must be used, which increases the distance of protruding from the bottom of the storage boxes reinforcing elements. Despite the solutions known from the prior art, therefore, the use of waterproof, equipped with a joint plate reinforcement connections remains limited to relatively small reinforcement diameter and large widths.
Aufgabe der vorliegenden Erfindung ist es daher ein mit einem Fugenblech ausgestattetes Bewehrungsanschlusselement zur Verfügung zu stellen, das auch für große Bewehrungsdurchmesser und geringe Bügelbreiten geeignet ist. Diese Aufgabe wird erfindungsgemäß durch das Bewehrungsanschlusselement gemäß unabhängigem Anspruch 1 gelöst. Weitere vorteilhafte Aspekte, Details und Ausgestaltungen der Erfindung ergeben sich aus den abhängigen Ansprüchen, der Beschreibung sowie den Zeichnungen.The object of the present invention is therefore to provide a reinforcing connection element equipped with a joint plate, which is also suitable for large reinforcing diameters and small ironing widths. This object is achieved by the reinforcement connection element according to independent claim 1. Further advantageous aspects, details and Embodiments of the invention will become apparent from the dependent claims, the description and the drawings.
Die vorliegende Erfindung offenbart ein Bewehrungsanschlusselement gemäß Anspruch 1.The present invention discloses a reinforcing connection element according to claim 1.
Bei dem erfindungsgemäßen Bewehrungsanschlusselement wird also an Stelle der aus dem Stand der Technik bekannten zwei separaten Verwahrungskästen ein einziger Verwahrungskasten in Verbindung mit einem Fugenblech eingesetzt. Im Innenraum dieses Verwahrungskastens ist der im eingebauten Zustand im zweiten Betonierabschnitt angeordnete Fugenblechabschnitt vollständig untergebracht, sodass der Deckel des Verwahrungskastens nach Erstellen des ersten Betonbauteils in einem Zug abgezogen werden kann um die Bewehrung freizulegen. Durch den Wegfall der dem Fugenblech zugewandten Wandung der beiden schlittenartigen Verwahrungskästen sind geringere Breiten des Bewehrungsanschlusselements möglich. Das erfindungsgemäße Bewehrungsanschlusselement mit Fugenblech kann daher auch für geringe Mauerstärken oder für große Bewehrungsdurchmesser verwendet werden, was für die aus dem Stand der Technik bekannten Bewehrungsanschlusselemente mit Fugenblech nicht gilt.In the case of the reinforcement connection element according to the invention, instead of the two separate storage boxes known from the prior art, a single storage box is used in conjunction with a joint plate. In the interior of this storage box the arranged in the installed state in the second concreting joint plate portion is completely housed, so that the lid of the storage box can be deducted after creating the first concrete component in one go to expose the reinforcement. Due to the omission of the joint plate facing wall of the two carriage-like storage boxes are smaller widths of Reinforcement connection element possible. The reinforcing connection element according to the invention with joint plate can therefore also be used for low wall thickness or for large reinforcement diameter, which does not apply to the known from the prior art reinforcement connection elements with joint plate.
Die Verbindung von Fugenblech und Boden des Verwahrungskastens erfolgt bevorzugt durch Schweißen oder Clinchen. Bevorzugt ist der Boden des Verwahrungskastens in den dem Fugenblech benachbarten Bereichen umgekantet, um so eine größere Anlagefläche auszubilden.The connection of joint plate and bottom of the storage box is preferably carried out by welding or clinching. Preferably, the bottom of the storage box is folded over in the areas adjacent to the joint plate, so as to form a larger contact surface.
Gemäß einer bevorzugten Ausführungsform ist das Fugenblech im Wesentlichen senkrecht zum Boden des Verwahrungskastens orientiert. Zur Abdichtung der Arbeitsfuge zwischen dem ersten und dem zweiten Betonbauteil ist eine im Wesentlichen senkrechte Anordnung des Fugenblechs relativ zum Boden des Verwahrungskastens von Vorteil, da in diesem Fall das Fugenblech maximal weit in das jeweilige Betonbauteil eindringt. Bei einer von dieser senkrechten Orientierung abweichenden Anordnung des Fugenblechs kann durch Verwendung eines großflächigeren Fugenblechs die selbe Eindringtiefe sichergestellt werden. Bei einer nicht-senkrechte Orientierung des Fugenblechs können in bestimmten Fällen beispielsweise Lufteinschlüsse beim Vergießen des Betons verhindert werden.According to a preferred embodiment, the joint plate is oriented substantially perpendicular to the bottom of the storage box. For sealing the working joint between the first and the second concrete component, a substantially vertical arrangement of the joint plate relative to the bottom of the storage box is advantageous, since in this case the joint plate penetrates as far as possible into the respective concrete component. In an arrangement deviating from this vertical orientation of the joint plate, the same penetration depth can be ensured by using a larger-area joint plate. In a non-vertical orientation of the joint plate, for example, air pockets can be prevented during the casting of the concrete in certain cases.
Die Seitenwände und der Deckel des Verwahrungskastens werden bevorzugt aus einem metallischen Flachmaterial, insbesondere aus einem Stahlblech und besonders bevorzugt aus Schwarzblech gefertigt.The side walls and the lid of the storage box are preferably made of a metallic flat material, in particular of a steel sheet and particularly preferably of black sheet metal.
Der Boden des Verwahrungskastens besteht bevorzugt ebenfalls aus einem metallischen Flachmaterial, insbesondere aus einem Stahlblech und besonders bevorzugt aus Schwarzblech, kann aber auch aus einem durchbrochenen metallischen Flachmaterial, bevorzugt aus einem Streckmetall gefertigt sein. Durch die Durchbrechungen des Streckmetalls kann Betonschlempe leicht auf die gegenüberliegende Seite quellen, wodurch es zu einer besonders guten gegenseitigen Anbindung der beiden Betonierabschnitte kommt.The bottom of the storage box preferably also consists of a metallic flat material, in particular of a sheet steel and particularly preferably of black plate, but can also be made of a perforated metallic flat material, preferably made of an expanded metal. Through the perforations of the expanded metal concrete vat can swell easily on the opposite side, resulting in a particularly good mutual connection of the two concreting sections.
Der Boden des Verwahrungskastens wird durch das Fugenblech durchdrungen, sodass der Boden in zwei Bodenabschnitte unterteilt ist, wobei diese Bodenabschnitte relativ zum Fugenblech auf einander gegenüberliegenden Seiten angeordnet sind. Der erste Bewehrungselementabschnitt kann aus einfachen Stäben, aus Stäben mit endständigen Haken und aus Stäben mit Abwinklungen bestehen. Gemäß einer besonders bevorzugten Ausführungsform der vorliegenden Erfindung ist der erste Bewehrungselementabschnitt U-förmig ausgebildet, wobei die beiden Schenkel des U-förmigen ersten Bewehrungselementabschnitts den Boden des Verwahrungskastens auf einander in Bezug auf das Fugenblech gegenüberliegenden Bodenabschnitten durchdringen. Jedes Bewehrungselement weist gemäß dieser Ausführungsform einen U-förmigen Abschnitt auf, wobei jeweils ein Schenkel des U-förmigen Abschnitts jeweils einen Bodenabschnitt durchdringt.
