- the screws 22 are readjusted in terms of height over the entire circumference of the ring bed 19.
- a first annular tower member 24 is placed with its flanges on all threaded rods 3 of the anchor basket 1 and lowered to the top surfaces of the adjusting screws 22 of the leveling bolt 20.
- Fig. 8 shows the last step, the filling of the bedding 19 with grout 25, which includes the leveling bolts. After setting of the grout 25, the tower component 24 is fixed with nuts 26 on the threaded rods 3.
- FIG. 9 and FIG. 10 show in perspective view and in plan view a second embodiment of the invention.
- the anchor basket 30 here again has a multi-part anchor ring 31 lying below, from which threaded rods 32 arranged in pairs next to one another in the radial direction run upward.
- a ring template 33 is placed, which is composed of segments which are interconnected by connecting plates.
- Fig. 11 shows an enlarged section along the line XI-XI in Fig. 10
- the annular template 33 is also here about adjusting screws 35 with bar pieces 36, consisting of U-profiles with cover plates connected, which are spaced from each other on radially adjacent threaded rods 32 and there sit on nuts 37 ( Fig. 11 ).
- the load distribution ring 38 is lifted by means of adjusting screws 35 from the ring bed 43 produced in the concrete 18 upwards and the template parts 39, 40, 41 and 42 are removed.
- the load distribution ring 38 is again adjusted in terms of height and it is then placed in the annular bed 43 grout 44, which sets and then rests on the load distribution ring 38 aligned in height ( Fig. 12 ).
- the adjustment screws 35 are unscrewed from the load distribution ring 38 and the bar pieces 36 are removed with the nuts of the threaded rods 32.
- a circumferential annular flange 45 is pushed as the first component of the tube tower of the wind turbine on the threaded rods 32 until it is seated on the load distribution ring 38 and tightened with nuts.
- Fig. 13 shows this final state of the process with the idealized concrete foundation 46th
Abstract
