Prestressed steel anchorage

Abstract

prestressing steel anchorage, with at least one, in particular hollow cylindrical, base body (12), with at least one first fixing unit (14) arranged on the base body (12), which has at least one sleeve element (16) with an at least partially inclined, in particular conical, inner surface (18) and at least two clamping jaws (20) arranged within the sleeve element (16) for clamping fixation of a prestressing steel (22), and with a second fixing unit (24) arranged at least partially within the base body (12).

Claims

[1] Prestressing steel anchorage, with at least one, in particular hollow-cylindrical, base body (12), with at least one first fixing unit (14) arranged on the base body (12), which has at least one sleeve element (16) with an at least partially oblique, in particular conical, inner surface (18) and at least two clamping jaws (20) arranged within the sleeve element (16) for clampingly fixing a prestressing steel (22), and with a second fixing unit (24) arranged at least partially within the base body (12). [2] Prestressing steel anchorage according to claim 1, characterized by that the second fixing unit (24) has at least one sleeve element (26) guided axially within the base body (12) with an at least partially oblique, in particular conical, inner surface (28) and at least two clamping jaws (30) arranged within the sleeve element (26) for clampingly fixing a prestressing steel (22). [3] Prestressing steel anchorage according to one of the preceding claims, characterized by that the first fixing unit (14) has a spring element (32) which is supported with a first end on the clamping jaws (20) of the first fixing unit (14). [4] Prestressing steel anchorage according to one of the preceding claims, characterized by that the second fixing unit (24) has an actuating element (34) which is guided with a first end in the base body (12) and which is provided for a direct axial displacement of the sleeve element (26) of the second fixing unit (24). [5] Prestressing steel anchorage according to one of the preceding claims, characterized by that the second fixing unit (24) has a spring element (36) which is supported with a first end on the clamping jaws (30) of the second fixing unit (24) and with a second end on the actuating element (34) of the second fixing unit (24). [6] Prestressing steel anchorage according to one of the preceding claims, characterized by at least one elastic element (38), in particular a further spring element, which is arranged between the first fixing unit (14) and the second fixing unit (24) within the base body (12) and which is supported with a first end on the base body (12), in particular on a radial shoulder (40) of the base body (12), and with a second end on the sleeve element (26) of the second fixing unit (14). [7] Prestressing steel anchorage according to claim 6, characterized by that the at least one elastic element (38) is formed by a screw field. [8] Prestressing steel anchorage at least according to claim 6, characterized by that the at least one elastic element (38) is formed by a disc spring, in particular by a disc spring assembly. [9] Prestressing steel anchorage at least according to claim 4, characterized byin that the actuating element (34) is provided for compressing the elastic element (38) in the axial direction with a, in particular defined, force, wherein the clamping jaws (30) of the second fixing unit (24) are provided for opening upon actuation of the actuating element (34) and for sliding forwards with the actuating element (34) on the prestressing steel (22). [10] Prestressing steel anchorage according to claim 9, characterized by that the elastic element (38) is provided to tension the second fixing unit (24) and to move the strand (22) relative to the base body (12) upon relaxation following the compression. [11] Prestressing steel anchorage at least according to claim 9, characterized bythat the first fixing unit (14) is provided during an actuation of the actuating element (34) to fix the prestressing steel anchorage (10) relative to the prestressing steel (22) and / or a support (44).
