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.
Claims11
A formwork tie for connecting two formwork elements that are disposed opposite and at a distance from one another, comprising a tie rod including an external thread and a tie nut that is screwed onto the external thread, wherein the formwork tie comprises an anti-rotation element, which is non-rotatable and axially movable with respect to the tie rod, and the formwork tie comprises a releasable form fit coupling, by way of which the anti-rotation element can be releasably non-rotatably connected to the tie nut and be made to engage and disengage by an axial movement, wherein the anti-rotation element comprises a sleeve that is axially displaceable on the tie rod and that has an inner cross-section, corresponding to the cross-section of the tie rod, which holds the anti-rotation element non-rotatably on the tie rod by way of form fit.
A formwork tie for connecting two formwork elements that are disposed opposite and at a distance from one another, comprising a tie rod including an external thread and a tie nut that is screwed onto the external thread, wherein the formwork tie comprises an anti-rotation element, which is non-rotatable and axially movable with respect to the tie rod, and the formwork tie comprises a releasable form fit coupling, by way of which the anti-rotation element can be releasably non-rotatably connected to the tie nut and be made to engage and disengage by an axial movement, wherein the formwork tie comprises a releasable and/or rotatable securing element, by way of which the form fit coupling can be held releasably in engagement, and wherein the securing element can be rotated into a position on the tie nut in which no form fit exists in the axial direction between the tie nut and the anti-rotation element, so that the anti-rotation element can be released from the tie nut in the axial direction.
