  • the anchor points known from the prior art with a lead-through element or a receiving element with an internal thread for screwing in a front end of the anchor rod must each be brought into the appropriate position before the anchor rod is inserted, depending on whether the respective frame formwork element is used as a closing formwork element or used as a formwork element.
  • a disadvantage of the prior art is that the corresponding preparatory measures are not always taken, so that it is often only when the anchoring process is carried out that it is determined that, particularly in the case of the formwork element, the receiving element necessary for screwing the tip of the anchor rod is not in the working position. In this case, it is necessary for the operator to move to the rear of the formwork element in order to move the receiving element with the internal thread into the working position or to insert a joint nut. Particularly if the formwork element is in an elevated position, this process can be complex or require scaffolding or a ladder.
