Abstract

Anchoring and coupling for fiber plates comprises clamping one or more plates (3) between two steel sheets (1) serving for further anchoring, e.g. with pegs in concrete. The clamping effect in the middle region in the transverse direction of the plates is reinforced by additional measures. Preferred Features: The plates are additionally adhered one on top of the other over a particular length. The plates are additionally adhered to the clamping plates over a particular length. The additional clamping effect is achieved by a screw (7) pressing on an additional sheet (4).

Description

Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und werden im folgenden näher beschrieben.Embodiments of the invention are shown in the drawings and are described in more detail below.

Für eine Lamellenkopplung kann eine Ausführung gemäß Fig. 1 gewählt werden. Die beiden CFK-Lamellen (3) und das Klemmblech (6) werden untereinander mittels eines gefüllten Epoxydharzklebers (8) verbunden. Nach Erhärten des Systems werden die Klemmplatten (4) mittels seitlich der Lamellen (3) angeord­ neten vorgespannter hochfester Klemmschrauben (6) zusammengespannt. Die Mittelschraube (7) wird im Anschluss daran kontrolliert angezogen, bis die Pressung in der Mitte der Lamelle und am Rand annähernd gleich ist.An embodiment according to FIG. 1 can be selected for a multi-plate coupling. The two CFRP slats ( 3 ) and the clamping plate ( 6 ) are connected to each other by means of a filled epoxy resin adhesive ( 8 ). After the system has hardened, the clamping plates ( 4 ) are clamped together by means of prestressed high-strength clamping screws ( 6 ) arranged on the side of the lamellae ( 3 ). The center screw ( 7 ) is then tightened in a controlled manner until the pressure in the middle of the lamella and at the edge is approximately the same.

In einer nicht dargestellten Ausführung ist die Mittelschraube (7) durch ein Federelement ersetzt, das zwischen den Klemmschrauben (6) montiert, in deren Mitte mit der erforderlichen Kraft auf die Klemmplatte (1) drückt.In an embodiment not shown, the central screw ( 7 ) is replaced by a spring element which is mounted between the clamping screws ( 6 ), in the middle of which presses the clamping plate ( 1 ) with the required force.

Für den Einsatz als Endverankerung wird die untere Klemmplatte (1) durch eine Grundplatte (2) ersetzt, die durch Dübel in den Löchern oder angeschweißte Kopfbolzendübel eine Eintragung der Vorspannkräfte in das vorzuspannende Bauteil sicherstellen.For use as end anchoring, the lower clamping plate ( 1 ) is replaced by a base plate ( 2 ), which ensures entry of the prestressing forces into the component to be prestressed by means of dowels in the holes or welded-on stud bolts.

Sollen mehrere Lamellen (3) verankert werden, so ist zwischen den einzelnen Lamellen (3) jeweils ein Zugblech (5) einzukleben, das die Lasten der einzelnen Lagen lokal über ein Aussteifungsblech (9) zur Grundplatte (2) weiterleitet. If several lamellae ( 3 ) are to be anchored, a tension plate ( 5 ) must be glued between the individual lamellae ( 3 ), which transmits the loads of the individual layers locally via a stiffening plate ( 9 ) to the base plate ( 2 ).
