Abstract
The invention relates to a tension anchor (1) made of fiber-reinforced plastic material, comprising an anchor rod (2) which consists of fiber-reinforced plastic material and at least on a sub-region comprises an anchor thread (6), an anchor plate (5) which consists of fiber-reinforced plastic material and comprises an anchor hole bore (15) through which the anchor rod (2) is guided, and an anchor nut (3) which consists of fiber-reinforced plastic material and has an internal thread and which can be screwed onto the anchor thread (6) of the anchor rod (2) and can be supported against the anchor plate (5). The anchor plate (5) is provided with a curved support surface (14), which cooperates with a complementary contact surface (12) that is associated with the anchor nut (3) such that the anchor rod (2) can be tilted obliquely with respect to the anchor plate (5) in at least one direction by an angle (a). The anchor nut (3) engages with a through-hole (21) of a seat ring (4), which preferably consists of fiber-reinforced plastic material, and the anchor nut (3), on the outside, comprises a conical region (8) with which it rests against a complementary inner cone (11) of the seat ring (4). At least one, preferably axially parallel, slot (9) is provided in the conical region (8) of the anchor nut (3) and interrupts the nut wall at least over a sub-region of the conical region (8). The complementary contact surface (12) cooperating with the curved support surface (14) of the anchor plate (5) is designed on the seat ring (4).
