shaped flat portion 19 of the suspension means which protrudes laterally from the wing 16 and perpendicularly from the region 18 with the circular diameter such a suspension means with the region 18 and the portion 19 can as fig2 and 3 also show be brought into a hole 12 of a side wall which is accessible from the top of a horizontally extending crossbar 2 in order thus to suspend the corresponding part of the anchoring system on the rear side of a closing formwork in the desired position in a reliable and stable manner the region 18 with the circular cross section is adapted to the cross section of a hole 12 and fills it by more than 50 in the suspended state the underside of each wing 16 is plane so that it is able as is shown in fig3 to rest flat on a side wall of a crossbar 2 the distance between the anchoring rod 4 with the threaded portion 17 and the suspension means with the region 18 corresponds to the distance of a hole 12 from the rear side 20 of the crossbar 2 so that an anchoring rod 4 with the thread 17 is adjacent to or rests on the crossbar 2 in the suspended state which stabilizes the position of the suspended anchoring rod 4 as a whole the part.
