Abstract

The invention relates to a shear connector (3) which is used to link, in a rectangular reinforced concrete sandwich slab, the outer concrete slab with the inner concrete slab by way of an insulating layer.

Description

Nerbundanker für rechteckige Stahlbetonschichtenplatten Nerbund anchor for rectangular reinforced concrete slabs

Stand der TechnikState of the art

Die Erfindung betrifft einen Nerbundanker, der dazu dient, eine Betonaußenplatte (Norsatzschale) durch eine Isolationsschicht hindurch mit einer Betoninnenplatte (Tragschale) zu verbinden.The invention relates to a Nerbund anchor, which is used to connect an outer concrete slab (Norsatzschale) through an insulation layer with a concrete inner slab (support shell).

Solche Nerbundanker und deren Anordnung sind bereits aus den Druckschriften DE 2760190 sowie DE 278098 bekannt. In diesen Druckschriften werden Stahlbetonaußenplatte und Stahlbetoninnenplatte mit Hilfe von rechteckigen Ankern aus Blech oder aus rechteckigen Stabrahmen mit Fachwerksaussteifung vereinigt. Die dort beschriebenen Flachanker haben jedoch einen entscheidenden Nachteil, sie ragen über die im Bauteil vorhandene Bewehrung hinaus, um den Einbau der lasteinleitenden Rundstäbe unterhalb der Bauteilbewehrung zu gewährleisten (siehe Figur 4) . Deshalb muß wegen einer erforderlichen Betonüberdeckung des Flachankers im Bereich der Betonaußenplatte diese dicker ausgeführt werden als nötig.Such anchor bolts and their arrangement are already known from the documents DE 2760190 and DE 278098. In these publications, reinforced concrete outer plate and reinforced concrete inner plate are united with the help of rectangular anchors made of sheet metal or from rectangular bar frames with truss bracing. However, the flat anchors described there have a decisive disadvantage, they protrude beyond the reinforcement in the component to ensure the installation of the load-introducing round bars below the component reinforcement (see Figure 4). Therefore, because of the required concrete coverage of the flat anchor in the area of the concrete outer slab, it must be made thicker than necessary.

Die Aufgabe des erfindungsgemäßen Nerbundanker (Figur 1) ist es nun, Betonaußenplatte mit Betoninnenplatte durch eine Isolationsschicht hindurch zu verbinden, aber dabei die Ausführung dünnerer Außen- und Innenplatten zu ermöglichen sowie gleichzeitig Zeit und Geld zu sparen. Durch Erzielung einer dünneren Außenplatte kann das Gewicht und damit auch die Kosten für Herstellung und Transport erheblich reduziert werden. Ebenfalls soll der Einbau des Nerbundankers in die Schalung erleichtert werden . Diese Aufgabe löst der erfindungsgemäße Nerbundanker (Figur 1) durch die besonderen Ausführungsformen wie sie beispielhaft in Figur 1 bis Figur 3 dargestellt sind. Durch die hakenförmige Abbiegung (2) des Nerbundankerendes oder auch beider Enden ( s.a. Figur 3; 2 und 2'), ist es nicht mehr erforderlich, dass ein erheblicher größerer Überstand im Bewehrungsbereich der jeweiligen Betonplatte gegeben sein muß. Der Einbau des Verbundankers (Figur 1) erfolgt dabei nämlich durch Einhängen (6) in eine im Bauteil bereits vorhandene Bewehrungsmatte (7) bzw. einzelne,nachträglich ins Bauteil eingelegte Bewehrungstäbe (8). Ein mögliches Umkippen oder Umfallen des Nerbundankers wird durch entsprechend eingebrachte Rundstahllängsabschnitte (3) zum Beispiel auch Bewehrungsstählen verhindert. Damit ist die Lagesicherheit des Nerbundankers (1) beim Betoniervorgang der Vorsatzschale, sowie beim Einbringen der Isolationsschicht und des späteren betonieren der Tragschale gewährleistet.The task of the Nerbund anchor according to the invention (FIG. 1) is now to connect the concrete outer slab to the concrete inner slab through an insulation layer, but to enable the execution of thinner outer and inner slabs and at the same time to save time and money. By achieving a thinner outer panel, the weight and thus the costs for production and transportation can be significantly reduced. The installation of the Nerbund anchor in the formwork should also be made easier. The Nerbund anchor according to the invention (FIG. 1) solves this problem by means of the special embodiments as exemplified in FIGS. 1 to 3. Due to the hook-shaped bend (2) of the Nerbund anchor end or both ends (see also Figure 3; 2 and 2 '), it is no longer necessary that there is a significant larger protrusion in the reinforcement area of the respective concrete slab. The installation of the shear connector (Figure 1) takes place by hanging (6) into a reinforcement mat (7) already in the component or individual reinforcement bars (8) inserted into the component afterwards. A possible overturning or overturning of the Nerbund anchor is prevented by appropriately inserted round steel longitudinal sections (3), for example also reinforcing steel. This ensures the positional security of the Nerbund anchor (1) during the concreting process of the facing shell, as well as when installing the insulation layer and later concreting the supporting shell.

Besonders vorteilhaft ist hierbei, daß das Einbringen der Verdreh- und Verkippsicherung in Form von Rundstahlabschnitten (3) einfach möglich ist. Hierzu wird das hakenförmige (2;'2Λ) Ende des Verbundankers in die Bewehrung eingehängt und durch Rundstahllängsabschnitte (3) in Ihrer Lage fixiert. Es sind deshalb keine zusätzlichen Mittel mehr erforderlich um den Verbundanker (1) in oder an der Bewehrungsmatte bzw. einzelne durch einzelne ins Bauteil eingelegte Bewerhungsstäbe zu fixieren. Anstelle der Durchbrechungen (4) im Innenbereich des Verbundankers (1) sind auch Langlöcher (5) im Randbereich des Verbundankers (1) vorstellbar, die die Rundstahllängsabschnitte (3) zur Fixierung aufnehmen. Die Anordnung und Anzahl der Durchbrechungen (4) bzw. Langlöcher (5) im Verbundanker ist so vielfältig, dass auf die Anforderung der Durchbrechungen (4) bzw. Langlöcher (5) im Verbundanker zur Aufnahme verschiedenster Rundstahldurchmesser reagiert werden kann. Deshalb wurde auf eine zeichnerische Darstellung in entsprechenden Figuren verzichtet.It is particularly advantageous here that it is easy to introduce the anti-twist and tilt protection in the form of round steel sections (3). For this purpose, the hook-shaped (2; '2 Λ ) end of the composite anchor is hooked into the reinforcement and fixed in its position by round steel longitudinal sections (3). It is therefore no longer necessary to fix the composite anchor (1) in or on the reinforcement mat or individual reinforcement bars inserted into the component. Instead of the openings (4) in the inner region of the composite anchor (1), elongated holes (5) in the edge region of the composite anchor (1) are also conceivable, which receive the round steel longitudinal sections (3) for fixing. The arrangement and number of openings (4) or elongated holes (5) in the composite anchor is so varied that the request for openings (4) or elongated holes (5) in the composite anchor can be used to accommodate various round steel diameters. Therefore, a graphic representation in corresponding figures has been omitted.

Weiterhin ist es auf Grund der naßlichen Ausgestaltung des Verbundankers nicht mehr Erforderlich , einzelne Stäbe einer im Bauteil möglicherweise vorhandenen Bewehrungs- Matte (7) herauszuschneiden, um den Verbundanker einzubauen. Denn der Einbau ist Immer innerhalb eines handelsüblichen Baustahlmattenquadrates (10) möglich. Diese Lösung spart somit nicht nur Einbaumaterialen sondern reduziert auch erheblich die Arbeitszeit die erforderlich ist, um einen solchen Verbundanker einzubauen. ZeichnungenFurthermore, owing to the wet design of the composite anchor, it is no longer necessary to cut out individual bars of a reinforcement mat (7) which may be present in the component in order to install the composite anchor. Because installation is always possible within a standard construction steel mat square (10). This solution not only saves installation materials but also significantly reduces the working time required to install such a composite anchor. drawings
