The tie rod comprises a screwing disc (3) and a hollow anchoring rod (2) pointed at one end (5) and having an attachment device (6) with a support plate (7) at its upper end (4). The support plate (7) is slidingly mounted and coaxially to the anchoring rod (2). On the anchoring rod (2) there is mounted a moving foot (15) between the screwing disc (3) and a stop (29). The foot (15) has a sleeve (16) movable on the anchoring rod (2); on the sleeve (16), supports (17a, 17b, 17c) are arranged radially. The support surfaces (18a, 18b, 18c) of the supports (17a, 17b, 17c) are directed towards the screwing disc (3) and go beyond said disc in the radial direction. An outer thread (32) is formed on the anchoring rod (2); a nut (31) is screwed on this threading. The nut (31) may be secured on the upper surface (33) of the sleeve (16) of the foot (15). A threaded sleeve (8) is arranged at the upper end (4); within this sleeve, a threaded bolt (9) is introduced. The support plate (7) is fixed at the free end (10) of the threaded bolt (9). |
