The invention relates to an anchoring system for a wall formwork and to a method for an assembly of the anchoring system: • the two wall formworks (1, 2, 3, 40) are set up opposite from each other, • an anchoring rod (4) with a graduation (21) is pushed through anchoring rod bores of the two wall formworks (1, 2, 3, 40) in such a way that the end of the anchoring rod (4) that has not been pushed through has the graduation (21), • the pushed-through end of the anchoring rod (4) is connected to a locking device (41) present on the rear side of the one formwork (40), • the end of the anchoring rod (4) that has not been pushed through is connected to the locking device (5, 6, 7, 8, 13, 14, 15) provided here in such a manner that this connection is aligned with the selected graduation, • the locking device aligned with the graduation is connected to the adjacent wall formwork (1, 2, 3).
