Claims (7)

1. Dehnschraube, mit einer in einem Loch eines Gegenstandes (8) eingeführten Schraube (4), welche an einem Ende einen Schaft (44) und einen sich daran anschließenden konischen Kopf (42) aufweist, welcher ausgehend von dem Schaft (44) in axialer Richtung einen kontinuierlich ansteigenden äußeren Durchmesser aufweist, mit einer Ummantelung (5), welche im Bereich des Schaftes (44) der Schraube (4) vorgesehen ist, und die Schraube (4) in dem Loch des Gegenstandes (8) zu befestigen, in dem die Schraube (4) eingeführt ist, wobei die Ummantelung (5) eine Vielzahl von axial verlaufenden Schlitzen (51) aufweist, welche in Richtung des konischen Kopfes (42) der Schraube (4) verlaufen, und mit einem Schraubenmutterelement (6), welches auf die Schraube (4) aufschraubbar ist, wobei beim Aufdrehen die Ummantelung (5) axial zum konischen Kopf (42) der Schraube (4) bewegt wird, sodass die in dem Loch eingeführte Schraube (4) an der Innenwand des Loches des Gegenstandes (8) gesichert wird.1. Expansion screw, with a screw ( 4 ) inserted into a hole of an object ( 8 ), which has a shaft ( 44 ) at one end and an adjoining conical head ( 42 ) which starts from the shaft ( 44 ) in Axial direction has a continuously increasing outer diameter, with a casing ( 5 ), which is provided in the region of the shaft ( 44 ) of the screw ( 4 ), and to fix the screw ( 4 ) in the hole of the object ( 8 ) in which the screw ( 4 ) is inserted, the casing ( 5 ) having a plurality of axially extending slots ( 51 ) which run in the direction of the conical head ( 42 ) of the screw ( 4 ), and with a screw nut element ( 6 ), which can be screwed onto the screw ( 4 ), the casing ( 5 ) being moved axially to the conical head ( 42 ) of the screw ( 4 ) when the screw is unscrewed, so that the screw ( 4 ) inserted into the hole on the inner wall of the hole d object ( 8 ) is secured. 2. Dehnschraube nach Anspruch 1, dadurch gekennzeichnet, dass die Schraube (4) an wenigstens einem dem konischen Kopf (42) abgewandten Ende eine Werkzeugaufnahme aufweist.2. Expansion screw according to claim 1, characterized in that the screw ( 4 ) has a tool holder on at least one end facing away from the conical head ( 42 ). 3. Dehnschraube nach Anspruch 1, dadurch gekennzeichnet, dass die Ummantelung (5) wenigstens eine Innenverzahnung (52) aufweist, welche in eine Richtung ausgerichtet ist, und dass der Schaft (44) der Schraube (4) eine Vielzahl von Zähnen (442) aufweist, welche in eine Richtung derart ausgerichtet sind, dass sie mit der Innenverzahnung (52) der Ummantelung (5) in Eingriff stehen, um eine Bewegung der Ummantelung (5) relativ zur Schraube (4) zu verhindern.3. Expansion screw according to claim 1, characterized in that the casing ( 5 ) has at least one internal toothing ( 52 ) which is aligned in one direction, and that the shaft ( 44 ) of the screw ( 4 ) has a plurality of teeth ( 442 ) which are aligned in one direction in such a way that they engage with the internal toothing ( 52 ) of the casing ( 5 ) in order to prevent movement of the casing ( 5 ) relative to the screw ( 4 ). 4. Dehnschraube nach Anspruch 3, dadurch gekennzeichnet, dass die Zähne (442) des Schaftes (44) der Schraube (4) nach außen hin in Richtung zu dem konischen Kopf (4) gerichtet sind.4. Expansion screw according to claim 3, characterized in that the teeth ( 442 ) of the shaft ( 44 ) of the screw ( 4 ) are directed outwards towards the conical head ( 4 ). 5. Dehnschraube nach Anspruch 1, dadurch gekennzeichnet, dass das Schraubenmutterelement (6) eine auf die Schraube (4) aufschraubbare Mutter (64) umfaßt und dass an einer Seite der Mutter (64) ein Hülsenelement (62) angeordnet ist, welche die Schraube (4) umhüllt und die Ummantelung (5) axial bei jeder Umdrehung der Mutter (64) auf der Schraube (4) axial vorwärts bewegt.5. Expansion screw according to claim 1, characterized in that the screw nut element ( 6 ) comprises a screw ( 4 ) screwable nut ( 64 ) and that on one side of the nut ( 64 ) a sleeve element ( 62 ) is arranged, which the screw ( 4 ) and the casing ( 5 ) moves axially forward with each rotation of the nut ( 64 ) on the screw ( 4 ). 6. Dehnschraube nach Anspruch 1, dadurch gekennzeichnet, dass der Außendurchmesser der Ummantelung (5) größer als der Außendurchmesser der Schraube (4) ist und dass der Innendurchmesser der Ummantelung (5) kleiner als der Außendurchmesser der Schraube (4), aber größer als der Außendurchmesser des Schaftes (44) ist.6. Expansion screw according to claim 1, characterized in that the outer diameter of the casing ( 5 ) is larger than the outer diameter of the screw ( 4 ) and that the inner diameter of the casing ( 5 ) is smaller than the outer diameter of the screw ( 4 ) but larger than the outer diameter of the shaft ( 44 ). 7. Dehnschraube nach Anspruch 5, dadurch gekennzeichnet, dass das Hülsenelement (62) des Schraubenmutterelementes (6) einen äußeren Durchmesser hat, der gleich dem äußeren Durchmesser der Ummantelung (5) ist und dass das Hülsenelement (62) an einem Ende der Ummantelung (5) anliegt.7. Expansion screw according to claim 5, characterized in that the sleeve element ( 62 ) of the nut element ( 6 ) has an outer diameter which is equal to the outer diameter of the casing ( 5 ) and that the sleeve element ( 62 ) at one end of the casing ( 5 ) is present.
