The invention relates to a system comprising a composite anchor bolt (10) and glue (12), wherein the bolt (10) can be screwed directly into a bore (14) that is at least partially provided with the glue (12) and is introduced in a fixed anchoring base (16), wherein the bolt (10) has a bolt head (18)
The invention relates to a system comprising a composite anchor bolt (10) and glue (12), wherein the bolt (10) can be screwed directly into a bore (14) that is at least partially provided with the glue (12) and is introduced in a fixed anchoring base (16), wherein the bolt (10) has a bolt head (18) having a tool application element, a substantially cylindrical shaft (20), and two or more, however, preferably three thread turns (22, 24, 26), which are disposed parallel to each other and extend helically at least partially across the length of the shaft (20), wherein the respective distance (p1, p2, p3) between the thread turns (22, 24, 26) is selected such that the glue (12) present in the bore (14) is evenly distributed between the wall (32) of the bore (14) and the bolt (10) upon screwing the bolt (10) into the bore (14).

1. A system comprising: a composite anchor bolt having: a bolt head with a tool application element;a substantially cylindrical shaft; andtwo or more thread turns arranged parallel to each other and extending helically at least partially along a length of the substantially cylindrical shaft;glue; anda fixed anchoring base having a borehole, the borehole having a wall and being at least partially provided with the glue; andwherein the composite anchor bolt is screwed directly into the borehole such that the composite anchor bolt is introduced into the fixed anchoring base;wherein via a respective distance between the two or more thread turns the glue present in the borehole is evenly distributed between the wall of the borehole and the composite anchor bolt after the composite anchor bolt is screwed into the borehole,wherein the two or more thread turns comprises a first thread turn, a second thread turn, and a third thread turn, andwherein a distance between the first thread turn and the second thread turn is different from a distance between the second thread turn and the third thread turn. 2. The system according to claim 1, wherein the first thread turn has a diameter different from a diameter of the second thread turn. 3. The system according to claim 1, wherein an outside diameter of the first thread turn is larger than an outside diameter of the second thread turn, the second thread turn following the first thread turn in a setting direction, and wherein the outside diameter of the second thread turn is larger than an outside diameter of the third thread turn, the third thread turn following the second thread turn in the setting direction. 4. The system according to claim 1, wherein the two or more thread turns form a threaded band and the threaded band helically extends at least partially across the length of the substantially cylindrical shaft. 5. The system according to claim 4, wherein via a pitch of the threaded band a threadless region between the substantially cylindrical shaft and wall of the borehole is present and is large enough to ensure optimal adhesion between the glue and the composite anchor bolt, as well as between the glue and the wall of the borehole. 6. The system according to claim 1, wherein the first thread turn has a flank angle different from a flank angle of the second thread turn. 7. The system according to claim 1, wherein outside diameters of the two or more thread turns are dimensioned in such a way that the two or more thread turns dig and furrow into the wall of the borehole while the composite anchor bolt is screwed into the borehole. 8. The system according to claim 1, wherein the glue is a chemically hardening glue. 9. The system according to claim 1, wherein a distance between the wall of the borehole and an outside of the substantially cylindrical shaft of the composite anchor bolt screwed into the borehole measures 0.1 to 1 mm.
