发明名称 Anchor head and anchor nut for a tension anchor
摘要 The invention relates to an anchor head (1) for anchoring a tension anchor (2) on the air side of an anchor bore (5), comprising an anchor nut (3) with a threaded bore (17) for screwing onto an anchor thread (19) of a tension anchor (2) and comprising an anchor plate (4) which interacts with the anchor nut (3) and comprises an anchor plate opening (8), said anchor plate being designed to transmit the tensile forces which can be exerted onto the anchor nut (3) by a screwed-in tension anchor (2) to a sub-surface (6) surrounding the anchor bore (5). The anchor nut (3) has a conical bearing region (7) which engages into the opening (8) of the anchor plate (4) in the assembled state and rests against a complementary inner cone (9) in the anchor plate opening, said anchor plate (4) having the inner cone at least in the region of the anchor plate opening (8). The anchor nut (3) has at least one slot (12) which runs preferably in an axially parallel manner and interrupts the nut wall over a sub-region of the axial extension of the wall. The at least one slot (12) opens into the air-side end (13) of the anchor nut (3) and from there extends over a length which equals between 25% and 90% of the total axial length of the anchor nut (3). The invention further relates to anchor nut (3) for such an anchor head (1).
