Tie device for connecting two formwork panels, has formwork tie with pole having longitudinal areas with different diameters, where diameters from head to thread of pole are reduced from one longitudinal area to another area

摘要

The device has a formwork tie (2) with a pole (3) and a head (4). A tie nut (6) is screwed on a thread (5) of the pole at the end of the tie and rotated relative to the head, where the end lies opposite to the head. The pole has longitudinal areas (7, 8, 9) with different diameters, where the diameters of the areas from the head to the thread of the pole (3) are reduced from one longitudinal area to another area.
