Abstract: A tie nut of a formwork tie for connecting two formwork elements is secured on a tie rod to prevent inadvertent rotation by way of a form fit coupling that can be axially made to engage therewith.

Abstract: A tie rod of a formwork tie for connecting two formwork elements, which are disposed opposite and at a distance from one another, is provided with two opposing flattened regions, and a tie nut is provided with a radial fixing screw, which can optionally be screwed against one of the two flattened regions for securing the tie nut on the tie rod, whereby the distance between the two formwork elements can be set in steps of one half a lead of an external thread of the tie rod.

Abstract: A seal for a lead-through for a tie rod through a panel formwork element. The seal includes a sleeve, a sealing element and a sliding tube, which are disposed on the tie rod and, together with the tie rod, are placed through the panel formwork element from a rear side, so that the sealing element exits the panel formwork element on a front side and, after brief pulling back of the tie rod, provides sealing between the sleeve and the panel formwork element, for one-sided anchoring.

Abstract: For one sided anchoring of two casing elements the invention proposes an anchor including an anchor rod with a thread and an anchor head that is rotationally fixed at the anchor rod to drive the anchor to rotate. A first reaction bearing is arranged at a fixed distance from the anchor head, wherein an enveloping tube that is arrangeable on the anchor rod is supported at the first reaction bearing, wherein a sleeve that forms a second reaction bearing for a casing element that is remote from the anchor head is arranged at another end of the enveloping tube. The invention facilitates one sided anchoring.
