A turnbuckle device (12, 13, 14; 20; 35a, 35b, 35c; 44a, 44b, 44c) for clamping concrete shell elements (1, 2), having two claws (15a, 15b, 15c, 16a, 16b, 16c; 21, 22) and a wedge (17a, 17b, 17c; 23; 37a, 37b, 37c; 46a, 46b, 46c), the claws being displaceable toward one another in a clamping direction (34), the wedge being guided in the clamping device along a wedge guiding direction (33), and the scale of the propulsion of the wedge in the turnbuckle device determining the displacement of the claws, is characterized in that the wedge guiding direction and the clamping direction enclose an angle less than 90°. Mutual obstruction of the turnbuckle devices neighboring wedges is thus avoided. |
